[0022] like Figure 1 、 Figure 2 and Figure 4 As shown, the cleaning assembly includes a pressure gauge 3, a drain pipe 1, a drain pipe 2 and a drain butterfly valve 4. The bottom of the air-water separator body 5 is connected and communicated with the drain pipe 2. The bottom of the drain pipe 2 is connected to the drain pipe 1 for discharging accumulated water. The upper end of the drain pipe 1 is equipped with a drain butterfly valve 4 for controlling the drain switch through bolts. A pressure gauge 3 for detecting the pressure of accumulated water is installed on the front side of the drain pipe 2, and the probe of the pressure gauge 3 is inserted into the drain pipe 2.

[0023] As Figure 2 , Figure 4 and Figure 5 shown, also includes a grooved plate 18, electric push rod 19, push plate 20, four corner frame 21, gasket 22, spring 23 and cover plate 24, the air-water separator body 5 bottom connected with grooved plate 18, drain pipe 2 through the grooved plate 18, the top surface of the grooved plate 18 is high on both sides and low in the middle, showing a large V-shaped, air-water separator body 5 lower side symmetry through bolt installation of electric push rod 19, electric push rod 19 telescopic rod into the air-water separator body 5, and the telescopic rod is connected with push plate 20, push plate 20 bottom surface with the shape of the grooved plate 18, and with the grooved plate 18, the upper side of the drain pipe 2 is connected with four corner frame 21, four corner frame 21 top surface four corners are connected with gasket 22, gasket 22 is used for sealing the contact surface between cover plate 24 and four corners of four corner frame 21, four corner frame 21 is connected with cover plate 24 slidingly, cover plate 24 and four corner frame 21 are connected with spring 23, cover plate 24 and drain pipe 2 are connected with sliding, cover plate 24 edge is circular arc, push plate 20 and cover plate 24 contact fit.

[0024] The device is used for processing gas extracted from mine environment and its accompanying water, coal slag and other impurities. The main purpose of the air-water separator body 5 is to separate the gas from liquid or solid impurities to ensure the efficient operation of the gas drainage system. In normal use, the first bypass butterfly valve 16 and the second bypass butterfly valve 17 in the bypass pipe 15 should be kept closed, the gas enters the air-water separator body 5 through the inlet pipe 9, after separation, it enters the next processing link through the outlet pipe 12. In daily use, the pressure of the water accumulated in the air-water separator body 5 can be understood by observing the pressure gauge 3.

[0025] The water separator body 5 is used for a long time, and water is accumulated inside. The groove-shaped plate 18 is arranged to enable the water to be accumulated in the middle. When the cover plate 24 is opened, the water flows to the drain pipe 2 through the four-corner frame 21. When the water needs to be cleaned, the electric push rod 19 is started first, the telescopic rod of the electric push rod 19 is extended to drive the push plate 20 to move inward, the push plate 20 pushes the accumulated water to the middle, and the accumulated water flows to the drain pipe 2. When the push plate 20 moves to contact the cover plate 24, the cover plate 24 is pushed to move downward, and the spring 23 is compressed, so that the cover plate 24 is in sealing contact with the four corners of the four-corner frame 21, thereby sealing the communication between the water separator body 5 and the drain pipe 2. The telescopic rod of the electric push rod 19 stops moving, and then the drain butterfly valve 4 is opened, so that the accumulated water in the drain pipe 2 is discharged through the drain pipe 1. In this way, the water separator body 5 can normally operate without the need to shut down the equipment. After the accumulated water is discharged, the drain butterfly valve 4 is closed, the telescopic rod of the electric push rod 19 is shortened to reset, the push plate 20 is driven to move outward to reset, and the push plate 20 is separated from the cover plate 24. The spring 23 rebounds to drive the cover plate 24 to move upward and separate from the four corners of the four-corner frame 21. The electric push rod 19 is automatically closed after resetting, and the accumulated water can normally flow to the drain pipe 2.

[0026] If the slag inside the water separator body 5 needs to be cleaned, the first bypass butterfly valve 16 and the second bypass butterfly valve 17 are opened first, and then the first butterfly valve 11 and the second butterfly valve 13 are closed. At this time, the gas will no longer enter the water separator body 5, but will directly pass through the bypass pipe 15 and be discharged to the next channel through the gas outlet pipe 12 for subsequent treatment, so as to ensure the normal operation of the equipment. Then, the fixed flange 8 is removed, and the impurities in the water separator body 5 can be cleaned through the slag removal port 7. After the cleaning is completed, the fixed flange 8 is reinstalled, and finally the first butterfly valve 11 and the second butterfly valve 13 are opened, and the first bypass butterfly valve 16 and the second bypass butterfly valve 17 are closed, so that the gas returns to the initial flow path.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the scope of protection of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the essence and scope of the technical solutions of the present application.
