Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The following describes in detail the specific technical scheme provided by the embodiment of the invention with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of the construction principle of a first embodiment of the electromagnetic valve emergency power supply apparatus according to the present invention, and as shown in fig. 1, the electromagnetic valve emergency power supply apparatus according to the embodiment of the present invention may include a power supply 10, a first switch 11, an inverter 12, a rectifier 13, a conversion part 14, and an electromagnetic valve interface part 15. The first output terminal 101 of the power supply 10 is electrically connected to the inverter 12 through the first switch 11, the input terminal of the rectifier 13 is electrically connected to the first output terminal 121 of the inverter 12, the output terminal of the rectifier 13 is electrically connected to the first input terminal 141 of the conversion component 14, and the output terminal of the conversion component 14 is electrically connected to the solenoid valve interface component 15. In addition, the second input 142 of the conversion element 14 may be directly electrically connected to the second output 122 of the inverter 12, and the third input 143 of the conversion element 14 may be directly electrically connected to the second output 102 of the power supply 10.
In the embodiment of the present invention, the power supply 10 mainly provides power for the electromagnetic valve emergency power supply device, which may include, but is not limited to, a storage battery or a lithium battery. In practical applications, the supply voltage of the power supply 10 may be set according to the input voltage of the inverter 12. When the first switch 11 is closed, the inverter 12 may invert the dc power provided by the power supply 10 to convert it into ac power. The rectifier 13 may perform voltage reduction, rectification, filtering and other processes on the ac power output by the inverter 12 to obtain dc power having a plurality of different voltage levels, and the output terminal of the rectifier 13 includes ports having a plurality of voltage levels, where the ports having a plurality of voltage levels respectively correspond to the dc power having a plurality of different voltage levels. Specifically, according to the voltage level of the solenoid valve, the switching part 14 selects a port of the output terminal of the rectifier 13 corresponding to the voltage level of the solenoid valve through the first input terminal 141 thereof, and outputs a corresponding direct current to the solenoid valve interface part 15, thereby supplying power to the solenoid valve.
In the case where the power supply voltage of the solenoid valve is alternating current, the conversion section 14 may directly select the second output terminal 122 of the inverter 12 through the second output terminal 122 thereof, thereby outputting alternating current inverter-converted via the inverter 12 to the solenoid valve interface section 15, thereby supplying power to the solenoid valve.
For example, in the embodiment of the present invention, the output voltage of the power supply 10 may be 12V dc, and after being processed by the inverter 12, the first output end 121 and the second output end 122 of the inverter 12 output 220V ac. The rectifier 13 steps down, rectifies, and filters the 220V ac power output from the first output terminal 121 of the inverter 12 to obtain dc power including, but not limited to, a voltage level of 12V and a voltage level of 24V. Accordingly, the output of rectifier 13 includes, but is not limited to, ports having 12V voltage levels and 24V voltage levels, corresponding to direct current having 12V voltage levels and 24V voltage levels, respectively. Thus, when the voltage level of the solenoid valve is 12V direct current, the switching part 14 selects the port of the rectifier 13 corresponding to the output end of the 12V direct current through the first input end 141 thereof, and outputs the 12V direct current to the solenoid valve interface part 15, thereby supplying power to the solenoid valve; when the voltage level of the solenoid valve is 24V direct current, the switching part 14 selects a port of the rectifier 13 corresponding to the output end of the 24V direct current through the first input end 141 thereof, and outputs the 24V direct current to the solenoid valve interface part 15, thereby supplying power to the solenoid valve. Of course, in the case of a direct current with a voltage level of 12V for the solenoid valve, the switching unit 14 may directly select the second output terminal 102 of the power supply 10 through the third input terminal 143 thereof and output the direct current with a voltage level of 12V to the solenoid valve interface unit 15, thereby supplying power to the solenoid valve. In addition, when the power supply voltage of the solenoid valve is ac, the conversion part 14 may directly select the second output terminal 122 of the inverter 12 through the second input terminal 142 thereof, and output 220V ac power output from the second output terminal 122 of the inverter 12 to the solenoid valve interface part 15, thereby supplying power to the solenoid valve.
In a specific implementation process, if a control circuit of an electromagnetic valve for controlling a feeding valve in a feeding system of a blast furnace smelting furnace fails, at this time, the electromagnetic valve cannot control the opening or closing of the feeding valve of the feeding system of the blast furnace smelting furnace because the electromagnetic valve cannot be provided with power, so that the blast furnace smelting furnace cannot normally smelt. In order to ensure that the electromagnetic valve can normally act without affecting the working efficiency of the blast furnace smelting furnace feeding system, an electromagnetic valve plug on a control line with faults can be pulled out, an electromagnetic valve interface part 15 of the electromagnetic valve emergency power supply device provided by the embodiment of the invention is connected to the electromagnetic valve, a first switch 11 is closed, the voltage level of the electromagnetic valve is confirmed, and then the electromagnetic valve plug on the control line is connected to the electromagnetic valve in an inserting way by utilizing a conversion part 14 to select the output ends of a power supply 10, an inverter 12 and a rectifier 13 corresponding to the proper voltage level, so that the electromagnetic valve is powered by the electromagnetic valve emergency power supply device provided by the embodiment of the invention, the blast furnace smelting furnace feeding system can normally work, and an overhauling personnel overhauls the control line of the electromagnetic valve at the same time.
If control lines of a plurality of electromagnetic valves in the feeding system of the blast furnace smelting furnace fail, a plurality of electromagnetic valve emergency power supply devices can be correspondingly and electrically connected with a plurality of failed electromagnetic valves so as to supply power to the electromagnetic valves. In general, the types of the electromagnetic valves in the feeding system of the blast furnace smelting furnace are the same, and if the types of the electromagnetic valves in the feeding system of the blast furnace smelting furnace are different, in the embodiment of the present invention, the electromagnetic valve interface members 15 may be plural.
According to the electromagnetic valve emergency power supply equipment provided by the embodiment of the invention, the power supply 10, the first switch 11, the inverter 12, the rectifier 13, the conversion part 14 and the electromagnetic valve interface part 15 are arranged, when a control circuit of the electromagnetic valve fails, the electromagnetic valve interface part 15 is electrically connected with the electromagnetic valve with failure, the first switch 11 is closed, and the conversion part 14 is used for selecting proper working voltage from the output ends of the power supply 10, the inverter 12 or the rectifier 13 and outputting the working voltage to the electromagnetic valve, so that the electromagnetic valve can normally act, and the continuous smelting of the blast furnace smelting furnace charging system is maintained. The electromagnetic valve emergency power supply equipment provided by the embodiment of the invention can ensure continuous smelting when the control circuit of the electromagnetic valve in the feeding system of the blast furnace smelting furnace fails, and improves the smelting efficiency of the blast furnace smelting furnace.
Fig. 2 is a schematic diagram of the construction principle of a second embodiment of the electromagnetic valve emergency power supply device according to the present invention, as shown in fig. 2, and the electromagnetic valve emergency power supply device according to the embodiment of the present invention may further include a first controller 16 on the basis of the embodiment shown in fig. 1. Wherein the first controller 16 is electrically connected between the switching member 14 and the solenoid valve interface member 15, whereby the output of the switching member 14 can be electrically connected with the solenoid valve interface member 15 through the first controller 16.
In a specific implementation, the types of solenoid valves may be different, and the power supply modes required may be different, so the power supply modes of the solenoid valves may be controlled by the first controller 16 in the embodiment of the present invention. For example, if the solenoid valve is a one-way solenoid valve, the first controller 16 may be a first relay, the output end of the conversion component 14 is electrically connected to the solenoid valve interface component 15 through the first relay, and the solenoid valve is continuously powered by the self-locking mode of the first relay, for example, the power taking mode may be that the power is directly taken from the second output end 102 of the power supply 10 through the third input end 143 of the conversion component 14 as described above. Alternatively, if the solenoid valve is a reversing solenoid valve, the first controller 16 may be a button controller, and the output end of the switching unit 14 is electrically connected to the solenoid valve interface unit 15 through the button controller. Specifically, the button controller is implemented in a button electric mode, so that the power output by the conversion component 14 can be output in a pulse form, and the power can be disconnected after the electromagnetic valve finishes corresponding actions.
In practical applications, the switching unit 14 of the embodiment of the present invention may be a second relay, where an output end of the second relay is electrically connected to the electromagnetic valve interface unit 15, and the second relay may directly take power from the second output end 102 of the power supply 10 as described above. For example, the output of the second relay is electrically connected to the solenoid valve interface 15 via a first control 16 in the form of a first relay or a push button control. Alternatively, the switching unit 14 of the embodiment of the present invention may be a switch, and an output end of the switch is electrically connected to the solenoid valve interface unit 15. The output of the change-over switch is electrically connected to the solenoid valve interface 15, for example, via a first control 16 in the form of a first relay or a push-button control.
In order to further improve the smelting efficiency of the feeding system of the blast furnace smelting furnace, as shown in fig. 2, the electromagnetic valve emergency power supply device of the embodiment of the invention may further comprise an external power interface part 17 and a second controller 18, wherein the external power interface part 17 is electrically connected to the electromagnetic valve interface part 15 and the second controller 18 respectively, and the second controller 18 is electrically connected to the first switch 10.
In a specific implementation process, a control circuit of the electromagnetic valve is electrically connected with the external power interface component 17 in the electromagnetic valve emergency power supply device according to the embodiment of the invention, and the electromagnetic valve interface component 15 is electrically connected with the electromagnetic valve. The second controller 18 is able to detect whether the control line is normal and the voltage level on the control line. If the control circuit is detected to be normal, the second controller 18 controls the first switch 10 to be turned off, the electromagnetic valve emergency power supply device of the embodiment of the invention is in an inactive state, an external power supply, the control circuit, the external power supply interface part 17, the second controller 18, the electromagnetic valve interface part 15 and the electromagnetic valve form a loop, and the electromagnetic valve normally works. If an abnormality of the control circuit is detected, the second controller 18 controls the first switch 10 to be turned on, and the electromagnetic valve emergency power supply device in the embodiment of the present invention enters a working state and performs emergency power supply on the electromagnetic valve according to the power supply principle described above, which is not described herein.
By utilizing the electromagnetic valve emergency power supply equipment provided by the embodiment of the invention, whether the control circuit of the electromagnetic valve is normal or not can be automatically judged, and when the control circuit of the electromagnetic valve is abnormal, the electromagnetic valve emergency power supply equipment is automatically controlled to enter the working state, so that the smelting efficiency of a blast furnace smelting furnace feeding system is further improved.
On the other hand, when the control circuit of the electromagnetic valve fails, the electromagnetic valve emergency power supply equipment can automatically enter a working state to maintain continuous operation of the blast furnace smelting furnace charging system, so that an operator does not know that the control circuit fails, the power supply of the electromagnetic valve emergency power supply equipment is limited, and the situation of failure can be known only when the power supply electric quantity of the electromagnetic valve emergency power supply equipment is exhausted, and therefore, as shown in fig. 2, the electromagnetic valve emergency power supply equipment of the embodiment of the invention can further comprise an alarm 19. The second controller 18 is also electrically connected to the alarm 19 and the power supply 10, respectively. If the second controller 18 detects that the external power interface part 17 has an abnormal condition, the second controller 18 controls the alarm 19 to send out a first alarm signal to prompt an operator to overhaul a control line with a fault. Or, in order to avoid the exhaustion of the power supply 10, if the second controller 18 detects that the power supply 10 has a power level less than the first preset threshold, the second controller 18 controls the alarm 19 to send out a second alarm signal to prompt the operator that the power supply of the solenoid valve emergency power supply device is low, and take relevant measures.
For example, the first alarm signal and the second alarm signal in the embodiments of the present invention may include, but are not limited to, a light signal and/or a sound signal. In order to be able to distinguish the reason why the alarm 19 is sent out, in the embodiment of the present invention, it is preferable that the first alarm signal and the second alarm signal are different, or a plurality of different alarms may be provided.
In practical application, the power supply 10 may be a charging power supply or a disposable power supply, and if the power supply 10 is a disposable power supply, an operator can replace the power supply 10 when knowing that the electric quantity of the power supply 10 is low through the alarm 19, so as to ensure that the electromagnetic valve emergency power supply device can normally supply power. If the power supply 10 is a charging power supply, an operator can charge the power supply 10 when knowing that the electric quantity of the power supply 10 is low through the alarm 19, so as to ensure that the electromagnetic valve emergency power supply equipment can normally supply power.
Fig. 3 is a schematic view illustrating the construction principle of a third embodiment of the solenoid valve emergency power supply apparatus according to the present invention, in which the power supply 10 is preferably a charging power supply for reducing the cost. In order to timely charge the electromagnetic valve emergency power supply device and reasonably utilize an external power supply, as shown in fig. 3, the electromagnetic valve emergency power supply device according to the embodiment of the present invention further may further include a charger 20 and a second switch 21 on the basis of the embodiment shown in fig. 2, where the external power supply interface part 17 is electrically connected with the charger 20 through the second switch 21, and the charger 20 is electrically connected with the power supply 10 through the second controller 18. Under normal conditions of the control circuit, the second controller 18 controls the second switch 21 to be closed, and the external power source can charge the power supply 10, so as to ensure that the electric quantity of the power supply of the electromagnetic valve emergency power supply device is sufficient in emergency. Considering that the service life of the power supply 10 is affected by the overcharge or overdischarge of the power supply 10, in the embodiment of the present invention, when the second controller 18 detects that the electric quantity of the power supply 10 is less than the first preset threshold value in the electrically connected state of the external power interface unit 17 and the external power supply, the second switch 21 is controlled to be closed, so that the external power supply charges the power supply 10; if the second controller 18 detects that the power of the power supply 10 is greater than the second preset threshold, the second switch 21 is controlled to be turned off, so that the external power supply stops charging the power supply 10.
In a specific implementation process, in order to facilitate carrying the electromagnetic valve emergency power supply device according to the embodiment of the present invention, as shown in fig. 3, the electromagnetic valve emergency power supply device may further include a case 22, where the power supply 10, the first switch 11, the inverter 12, the rectifier 13, the conversion component 14, the first controller 16, the second controller 18, the alarm 19, the charger 20, and the second switch 21 are disposed in the case 22, and the electromagnetic valve interface component 15 and the external power supply interface component 17 are disposed outside the case 22. Any one of the power supply 10, the first switch 11, the inverter 12, the rectifier 13, the conversion component 14, the first controller 16, the second controller 18, the alarm 19, the charger 20 and the second switch 21 may be detached, so that after a certain device fails, the device is replaced independently, thereby reducing maintenance cost.
It should be noted that, because the number of solenoid valves in the feeding system of the blast furnace smelting furnace is large, if each solenoid valve is provided with a solenoid valve emergency power supply device, the cost is high and the occupied space is large. Therefore, in practical application, an operator can select at least one important electromagnetic valve to correspondingly set an electromagnetic valve emergency power supply device according to the importance of each electromagnetic valve in the blast furnace smelting furnace feeding system, and other electromagnetic valves can carry the electromagnetic valve emergency power supply device to carry out emergency power supply on the corresponding electromagnetic valve on the failed control line when the control line of the electromagnetic valve fails.
The embodiment of the invention also provides a blast furnace smelting furnace feeding system which can comprise a charging tank, a feeding valve, an electromagnetic valve for controlling the feeding valve and the electromagnetic valve emergency power supply equipment provided by the invention, wherein the feeding valve is electrically connected with the electromagnetic valve, and an electromagnetic valve interface component of the electromagnetic valve emergency power supply equipment is connected with the electromagnetic valve in a pluggable manner.
In the blast furnace smelting furnace feeding system provided by the embodiment of the invention, when the control circuit of the electromagnetic valve fails, the electromagnetic valve emergency power supply equipment can supply power for the electromagnetic valve in an emergency manner as described above.
