Description

Technical Field

[0001] This utility model relates to slag removal and water discharge equipment for underground drainage pipelines, and particularly to a slag removal and water discharge device for mining. Background Technology

[0002] During the gas drainage process, the coal dust, rock dust, drilling water, and coal and rock seepage water that are broken during drilling inevitably enter the drainage pipeline through the pre-drainage borehole by their own weight and negative pressure. In particular, the drilling water introduced into the coal seam during the hydraulic permeability enhancement of the drainage borehole, mixed with a large amount of coal and rock dust, enters the drainage pipeline, which will cause local pipeline blockage and seriously affect the negative pressure drainage effect of gas. Therefore, it is particularly important to use a water drainer to discharge the accumulated water and slag in the drainage pipeline.

[0003] Existing mine slag removal and water discharge devices, such as the "Intelligent Mine Slag Removal and Water Discharge Device" disclosed in Chinese Patent CN116906115A, include a connecting pipe and a slag box and a storage water tank connected by the connecting pipe. A radar level sensor is installed at the top of the storage water tank, and a water outlet is installed at the bottom of the storage water tank. A slag box outlet is installed at the bottom of the slag box. In use, the slag removal and water discharge device is connected to a gas extraction pipeline. Water and accumulated slag in the gas extraction pipeline enter the storage water tank and the slag box. The lower end of the radar level sensor extends into the storage water tank to detect the water level. When the liquid level in the storage tank reaches a designated height, the water outlet opens to discharge water.

[0004] The existing slag removal and water discharge device has the following problems: The radar level detector in the current technology is a contact-type detector, with its lower sensing end extending into the storage tank. It detects the water level by contact with the water. Since the storage tank contains methane gas, static electricity may occur at the sensing end of the radar level detector, potentially causing a gas explosion. Therefore, the existing slag removal and water discharge device poses a significant safety hazard. Furthermore, the storage tank is under negative pressure. When the water tank outlet is opened, the negative pressure causes the drainage from the outlet to be less than smooth, affecting drainage efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a mine slag removal and water discharge device to solve the technical problems of safety hazards in existing contact radar level detectors and poor drainage at the water tank outlet under negative pressure.

[0006] To solve the above-mentioned technical problems, the technical solution of the mine slag removal and water discharge device of this utility model is as follows:

[0007] A mine slag removal and water discharge device includes a vertically arranged storage tank. The bottom of the storage tank has a water outlet, and an outlet valve is provided at the water outlet. The tank wall is connected to a water inlet for connecting to a corresponding gas extraction pipe. The mine slag removal and water discharge device also includes a two-position three-way valve with a first valve port, a second valve port, and a third valve port. The first valve port is used to communicate with the atmosphere, the second valve port is used to connect to the corresponding gas extraction pipe, and the third valve port is connected to the upper end of the storage tank. A non-contact liquid level sensor for detecting the liquid level in the storage tank is fixed to the upper end of the storage tank.

[0008] Furthermore, the upper end of the storage tank is provided with an upward-open detection port, and a non-contact liquid level sensor is detachably connected to the upper end of the detection port via a flange bolt connection structure.

[0009] Furthermore, an insulating pad is provided between the non-contact liquid level sensor and the detection port.

[0010] Furthermore, the non-contact liquid level sensor is a radar non-contact liquid level sensor.

[0011] Furthermore, the outlet valve is an outlet solenoid valve.

[0012] Furthermore, a feed switch valve is installed at the inlet of the water storage tank, and the feed switch valve is a solenoid valve.

[0013] Furthermore, the mine slag remover and water discharge device also includes a left support leg and a right support leg arranged at intervals. The right support leg is fixed to the bottom of the storage tank. The left side wall of the storage tank is connected to the inlet of the storage tank through a horizontal tank body. The left support leg is fixed to the left end of the horizontal tank body.

[0014] The beneficial effects of this utility model are as follows: In this utility model, the third valve port of the two-position three-way valve is connected to the upper end of the storage tank. During the normal slag and water removal process, the second valve port is connected to the third valve port, the first valve port is closed, the inlet of the water storage tank is connected to the gas extraction pipe, and the non-contact liquid level sensor is used to detect the liquid level in the storage tank in real time. When the liquid level reaches the set height, the second valve port is closed, the first valve port is connected to the third valve port, and the outlet valve is opened. In this way, the upper end of the storage tank is connected to the atmosphere through the first valve port. Under the action of atmospheric pressure, the water in the storage tank can be discharged quickly and efficiently through the outlet of the storage tank. In addition, the detection unit of the non-contact liquid level sensor is not connected to the inner cavity of the storage tank. Therefore, the safety hazards caused by the contact between electrical components and gas can be avoided. Attached Figure Description
