The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, according to an embodiment of the present application, an automatic charging control device is provided. The automatic liquid feeding control device comprises a liquid tank 2, a water level sensor 3, a controller 4 and a valve 6. Wherein, the liquid tank 2 is provided with a liquid inlet 22 and a liquid outlet 22, the liquid inlet 22 is arranged at the upper part of the liquid tank 2, and the liquid outlet 22 is arranged at the lower part of the liquid tank 2; the water level sensor 3 is at least partially arranged in the liquid tank 2, and the water level sensor 3 is provided with a low water level sensing point 32 capable of sensing the low water level in the liquid tank and a high water level sensing point 31 capable of sensing the high water level in the liquid tank; the controller 4 is in communication connection with the water level sensor 3; the valve 6 is arranged on the liquid inlet side and is in communication connection with the controller 4; the controller 4 controls the on-off state of the liquid inlet 22 and the liquid supply source by controlling the on-off state of the valve 6.
In the above embodiment, under the condition that the liquid tank 2 is in a normal use process, as the liquid in the liquid tank 2 continuously flows out from the liquid outlet 21, when the liquid level in the liquid tank 2 drops to the low water level sensing point 32 of the water level sensor 3, the water level sensor 3 will generate a voltage change signal and send the voltage change signal to the controller 4, and the controller 4 further opens the valve 6 to enable the liquid inlet 22 of the liquid tank 2 to be in a communication state with the liquid supply source, so as to add liquid; along with liquid continuously flows into the liquid tank 2 from the liquid inlet 22 of the liquid tank 2, when the liquid level in the liquid tank 2 rises to the high water level sensing point 31 of the water level sensor 3, the water level sensor 3 generates a voltage change signal again and sends the voltage change signal to the controller 4, and the controller 4 closes the valve 6 so that the liquid inlet 22 of the liquid tank 2 and a liquid supply source are in a disconnected state, thereby stopping liquid adding.
Specifically, the controller 4 may be a huaning remote controller, which may be installed between the water level sensor 3 and the valve 6, and connect the controller 4, the sensor 3, and the valve 6 with a 12v intrinsically safe control cable (the intrinsically safe control cable has a rated voltage value of 12 v).
Further, the liquid inlet 22 may be provided at an upper portion of a side surface of the liquid tank 2, and the liquid outlet 21 may be provided at a lower portion of the side surface of the liquid tank 3. More specifically, as shown in fig. 1, in the present embodiment, the liquid tank may have a square or rectangular parallelepiped structure, the liquid inlet 22 may be disposed at an upper portion of a first side surface of the liquid tank 2, and the liquid outlet 21 may be disposed at a lower portion of a second side surface of the liquid tank 3, where the first side surface is opposite to the second side surface.
Further, the low water level sensing point 32 of the water level sensor 3 may be disposed to be flush with the upper end of the liquid outlet 21; the high water level sensing point 31 of the water level sensor 3 may be disposed flush with the lower end of the liquid inlet 22. Therefore, when the water level in the liquid tank 2 drops to the upper end of the liquid outlet 21, the controller 4 opens the valve 6 to add liquid; when the water level in the liquid tank 2 rises to the lower end of the liquid inlet 22, the controller 4 closes the valve 6 to stop filling.
In the present embodiment, a part of the water level sensor 3 is disposed outside the liquid tank 2, and the controller 4 is connected to the part of the water level sensor 3 disposed outside the liquid tank 2 through a cable 5. For example, in fig. 1, the exposed end of the water level sensor 3 is connected to the left end of the controller 4 by a 12v intrinsically safe control cable.
In the present embodiment, the water level sensor may be an 800mm stroke water level sensor.
In this embodiment, the automatic liquid feeding control device further comprises a liquid inlet pipe 7 communicated with the liquid inlet 22, the valve 6 is fixed on the liquid inlet pipe 7, and the liquid inlet pipe 7 is further communicated with the liquid supply source. For example, the liquid inlet pipe 7 may further communicate with a pump station facility, the valve 6 is fixed with the liquid inlet pipe 7 using bolts, and the valve 6 is connected with the right side of the controller 4 through a 12v intrinsically safe control cable.
Specifically, the valve 6 may be an electric ball valve, so that the controller 4 controls the on/off of the electric ball valve to change the on/off state between the liquid inlet 22 and the liquid supply source.
In this embodiment, the water level sensor 3 may be inserted vertically into the liquid tank 2 from 1/4 near the top surface of the liquid outlet port downward. In practical application, a small hole slightly larger than the diameter of the water level sensor 3 is formed at the top of the liquid tank 2 close to the liquid outlet side 1/4, and the difference range between the diameter of the small hole and the diameter of the water level sensor 3 can be 1-5 mm; then, the water level sensor 3 is extended into the liquid tank from a small hole at the top of the liquid outlet side 1/4 of the liquid tank 2 to a position 4/5, so that the low water level sensing point 32 of the water level sensor 3 is flush with the upper end of the liquid outlet 21, and the water level sensor 3 is fixed to the top of the liquid tank 2, and the water level sensor 3 can be fixed to the top of the liquid tank 2 by adopting a welding process.
In this embodiment, after the water level sensor 3 and the valve 6 are fixed, the controller 4 is connected to the controller 4 by the 12v intrinsic safety control cable, and then the controller 4 is fixed to the top of the liquid tank between the water level sensor 3 and the valve 6 by bolts.
Due to the adoption of the technical scheme, the automatic liquid feeding control device can realize automatic liquid feeding control. When the liquid level of the liquid tank is reduced to the lowest water level sensing position of the water level sensor, the water level sensor transmits a signal to the remote controller, and the remote controller further controls a valve (such as an electric ball valve) to be opened to add liquid; when the liquid level of the liquid tank rises to the highest water level sensing position of the water level sensor, the water level sensor transmits a signal to the remote controller, and the remote controller further controls the valve (for example, an electric ball valve) to be closed to stop liquid adding. In field use, the device not only reduces the labor intensity of manually controlling the liquid feeding stop valve, saves time, but also effectively avoids the problems of damaging equipment due to the fact that the liquid feeding stop valve is not opened or closed timely, or wasting materials due to excessive liquid feeding and polluting the environment.
In order to meet the requirements of emulsion and clear water which are used in a large amount in the production and maintenance process of the underground working face, the personnel at the post are required to pay attention to the condition of the residual liquid amount in the liquid tank all the time, liquid is added to the liquid tank in time, and automatic liquid adding control devices are installed on the liquid tank, so that automatic liquid adding and liquid adding stopping of the liquid tank can be realized. Through utilizing automatic control liquid feeding device, replaced personnel to survey liquid tank liquid level and manual switch feed liquor stop valve, not only reduced post personnel's intensity of labour, but also effectual avoided the liquid feeding untimely, lead to the liquid tank to manage to find time and damage equipment, or close the stop valve untimely, the liquid feeding is excessive, leads to liquid to leak, causes the material extravagant, environmental pollution's risk, and easy operation is practical, the effect of acquireing is obvious, has produced huge safety and productivity effect.
In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.
