[0026] In this embodiment, a discharge port 5 is provided at the bottom of the housing 1 , and a baffle 6 is rotatably connected to the inner side of the discharge port 5 .

[0027] By rotating the baffle 6, the material falling from the discharge port 5 can be guided to different directions for dropping, which can be adjusted according to the usage.

[0028] In this embodiment, tubular protrusions are provided on both sides of the discharge port 5, and the baffle 6 has an elliptical shape.

[0029] The discharge port 5 discharges slag and water respectively through two tubular protrusions, thereby achieving slag-water separation.

[0030] In this embodiment, three circular holes are formed at the bottom of the rocker 7, and a circular protrusion is formed at one end of the latch pin 12.

[0031] The latch 12 can fix the rotating shaft 11 by inserting the circular protrusion into the circular hole of the rocker 7 .

[0032] In this embodiment, a groove is formed on the top of the rotating shaft 11 , and round holes are formed on both sides of the groove. Two round protrusions are formed on the other end of the latch 12 .

[0033] The rotating shaft 11 is connected to the latch 12 through a groove at the top, and the latch 12 can rotate around the connection point with the rotating shaft 11.

[0034] In this embodiment, a circular hole is formed on the top of the shaft sleeve 13 and extends to the bottom thereof, and a cavity is formed on the inner side of the fixing block 14 .

[0035] The rotating shaft 11 can rotate inside the shaft sleeve 13, and the cavity of the fixing block 14 can accommodate the driving wheel 15 and the driven wheel 16 inside and provide protection.

[0036] In this embodiment, a plurality of circular holes are opened on the outer circumference of the net cylinder 9, and a plurality of circular holes are opened on the top of the bottom plate 10 and penetrate to the bottom.

[0037] The mesh tube 9 and the bottom plate 10 cooperate to intercept the coal slag and allow water to flow through the circular holes to separate the coal slag and water.

[0038] It should be noted that the utility model is a U-shaped ventilation working face goaf sliding alternating buried pipe gas extraction device, which can collect coal slag and separate it from water when in use, and can also increase its dehydration effect. The specific implementation method is that the gas pipe 4 transports the extracted gas and the coal slag and water carried therein to the inside of the shell 1;

[0039] After the gas enters the housing 1, it is discharged through another gas pipe 4 on the top of the housing 1. The water and coal slag carried in the gas will fall under the action of gravity. The coal slag will be intercepted by the mesh tube 9 and the bottom plate 10 and stay in the cylindrical space formed by the bottom plate 10 and the mesh tube 9. The water carried in the gas will fall into the discharge port 5 through the circular holes of the bottom plate 10 and the mesh tube 9 and accumulate. It can be discharged through one of the pipes on the discharge port 5 under the guidance of the baffle 6, so as to achieve the separation of water and coal slag.

[0040] When the coal slag accumulates more, by rotating the rocker 7, the rocker 7 rotates and drives the fixed block 14 to rotate, the fixed block 14 drives the driven wheel 16 and the connecting rod 17 to rotate, the connecting rod 17 drives the net cylinder 9 and the bottom plate 10 to rotate, and the bottom plate 10 and the net cylinder 9 rotate and drive the internal coal slag to rotate together, and through the centrifugal force, the moisture in the coal slag is thrown out through the circular holes of the net cylinder 9 and the bottom plate 10, so that the coal slag is more fully dehydrated, which is convenient for subsequent utilization;

[0041] After the water in the shell 1 is drained, the baffle plate 6 is rotated to close the water outlet pipe and connect the other pipe. The connection between the latch 12 and the rocker 7 is released by lifting one end of the latch 12, and the rocker 7 is rotated. When the rocker 7 rotates, the shaft 11 can be driven to rotate. The shaft 11 drives the driving wheel 15 to rotate. When the driving wheel 15 rotates, the driven wheel 16 connected thereto is driven to rotate. The driven wheel 16 drives the connecting rod 17 and the bottom plate 10 to rotate. By controlling the bottom plate 10 to rotate downward to a vertical state, the coal slag on the bottom plate 10 falls into the discharge port 5, and the coal slag is discharged through another pipe on the discharge port 5, thereby completing the dehydration and discharge of the coal slag.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
