AI Technical Summary
The existing underground drilling truck water supply valves cannot effectively filter impurities in the water during the water supply process, resulting in damage to the water components of the drilling truck, shortening the service life and increasing maintenance costs.
By modifying the three-way valve, an obliquely arranged bypass pipe and filter plate are added, and combined with the water inlet pipe, drain pipe and sewage pipe, a system with filtering and sewage discharge functions is formed. After the water is inlet, it is filtered through the filter plate, and the impurities are isolated and stored in the bypass pipe. The filtered water is supplied to the equipment and impurities are discharged through the sewage pipe when necessary.
Effectively filter impurities in the water used for underground drilling vehicles, protect water components, extend the service life of the equipment, and reduce maintenance costs through regular sewage discharge.

Description
Technical Field
[0001] The utility model relates to the technical field of valves for mine pipelines, in particular to a sewage valve for purifying water used for rock drilling in underground mines. Background Art
[0002] An underground drilling vehicle is a piece of mechanical equipment used for drilling operations in mines. It is efficient, fast, flexible, and durable, and is an indispensable tool for mining. During its use, it will be connected to a water supply pipeline, which will be used for cooling and dust removal during operation.
[0003] The existing water supply pipeline for underground drilling vehicles has the following disadvantages in the water supply process: the water supply valve of underground drilling vehicles in mines usually adopts a direct connection type, that is, it is directly connected to the water inlet valve of the underground drilling vehicle in the mine through a water pipe, and the water for the drilling vehicle is directly supplied. In this way, various impurities in the water can easily enter the water-using equipment directly, damage the water-related parts of the drilling vehicle, reduce the service life of the drilling vehicle parts, and increase the maintenance cost. For this reason, we propose a drain valve for purifying water used in underground rock drilling in mines. Utility Model Content
[0004] The main purpose of the utility model is to provide a drain valve for purifying water used for rock drilling in underground mines. By modifying the three-way valve, it has good water supply, filtering and draining functions, can play a good filtering role on the water used for equipment, and can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A sewage valve for purifying water used for rock drilling in underground mines comprises a three-way valve, wherein the three-way valve comprises a bypass pipe arranged obliquely at the bottom, a water inlet pipe is installed at one end of the three-way valve, and a drainage pipe connected to the water supply pipeline of an underground drilling vehicle is installed at the other end of the three-way valve, a sewage pipe is arranged at the end of the bypass pipe, and a filter plate inserted into the three-way valve is installed obliquely inside the bypass pipe.
[0007] Furthermore, a water inlet valve for controlling the opening and closing of the water inlet end is installed at the end of the water inlet pipe, and a drain valve for controlling the opening and closing of the drain end is installed at the end of the drain pipe; the opening and closing of the water inlet pipe is controlled by the water inlet valve, and the opening and closing of the drain pipe is controlled by the drain valve.
[0008] Furthermore, a sewage valve for controlling sewage discharge is installed at the end of the sewage pipe; the isolated impurities will be retained inside the bypass pipe, and the sewage valve can be opened when necessary to discharge the impurities through the sewage pipe.
[0009] Furthermore, the bypass pipe and the three-way valve are at an angle of 45°; the bypass pipe and the three-way pipe are arranged obliquely, so that the filter plate can also be installed obliquely, which not only ensures the filtering of impurities but also reduces the impact on water supply.
[0010] Compared with the prior art, the utility model has the following beneficial effects: a modified three-way valve is connected to the water supply pipeline of the underground drilling vehicle, the bypass pipe on the surface of the three-way valve is facing the bottom when the three-way valve is installed, the water inlet pipe is connected to the water supply pipeline, the drainage pipe is connected to the water end of the equipment, and a filter plate structure is obliquely provided inside the bypass pipe. The water source supplied by the water inlet pipe will be filtered by the filter plate, and the impurities are isolated and stored in the gap between the filter plate and the bypass pipe. The filtered water is then supplied to the equipment to avoid damage to the water-related parts of the drilling vehicle and extend the service life of the drilling vehicle parts. When needed, the impurities trapped in the three-way valve can be discharged from the sewage pipe by regularly opening the sewage valve. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0014] like Figure 1 As shown, a sewage valve for purifying water used for rock drilling in underground mines comprises a three-way valve 1, wherein the three-way valve 1 comprises a bypass pipe 101 arranged obliquely at the bottom, a water inlet pipe 2 is installed at one end of the three-way valve 1, and a drainage pipe 3 connected to the water supply pipeline of the underground drilling vehicle is installed at the other end of the three-way valve 1, a sewage pipe 4 is arranged at the end of the bypass pipe 101, and a filter plate 402 inserted into the three-way valve 1 is installed obliquely inside the bypass pipe 101.
[0015] Among them, an inlet valve 201 for controlling the opening and closing of the water inlet end is installed at the end of the water inlet pipe 2, a drain valve 301 for controlling the opening and closing of the drain end is installed at the end of the drain pipe 3, and a drain valve 401 for controlling the discharge of sewage is installed at the end of the sewage pipe 4; the opening and closing of the water inlet pipe 2 is controlled by the water inlet valve, and the opening and closing of the drainage pipe 3 is controlled by the drain valve 301, and the isolated impurities will be retained inside the bypass pipe 101. When needed, the sewage valve 401 can be opened to discharge the impurities through the sewage pipe 4.
[0016] The bypass pipe 101 and the three-way valve 1 are at an angle of 45°; the bypass pipe 101 and the three-way pipe are arranged obliquely, so that the filter plate 402 can also be installed obliquely, which ensures the filtering of impurities and reduces the impact on water supply.
[0017] It should be noted that the utility model is a drain valve for purifying water used for rock drilling in underground mines. When in use, a modified three-way valve 1 is connected to the water supply pipeline of the underground drilling vehicle. When the three-way valve 1 is installed, the bypass pipe 101 on its surface faces the bottom, the water inlet pipe 2 is connected to the water supply pipeline, and the drain pipe 3 is connected to the water end of the equipment. A filter plate 402 structure is obliquely arranged inside the bypass pipe 101. The water source supplied by the water inlet pipe 2 will be filtered by the filter plate 402, and impurities are isolated and stored in the gap between the filter plate 402 and the bypass pipe 101. The filtered water is then supplied to the equipment to avoid damage to the water-related water-using components of the drilling vehicle and extend the service life of the drilling vehicle components. When needed, the drain valve 401 only needs to be opened regularly to discharge the impurities trapped in the three-way valve 1 from the drain pipe 4.
