Since the threaded rod 303 is threadedly and rotatably connected with the threaded hole, when the threaded rod 303 rotates, the support plate 301 can slide in the support frame 302, so that the height of the support assembly 3 can be adjusted.
[0027] Please refer to Figures 1-3A screening assembly 4 is movably mounted on the sludge discharge trough 1. The screening assembly 4 includes a screening trough 401 movably mounted on the top of the sludge discharge trough 1. A limiting frame 402 is fixedly mounted on the bottom of the screening trough 401, covering the bottom of the screening trough 401. A connecting cover 403 is movably mounted on the top of the screening trough 401. The screening trough 401 and the connecting cover 403 are connected by several screws 404 and nuts 405. The screws 404 are fixedly mounted on the screening trough 401 and movably pass through the connecting cover 403. The cover 403 has a through hole for the screw 404 to pass through. The internal structure of the screening tank 401 and the connecting cover 403 is cylindrical. Sealing strips are provided at the joints of the screening tank 401 and the connecting cover 403. A drain pipe 406 is fixedly and continuously provided at the bottom of the screening tank 401. The drain pipe 406 is bent. An inlet pipe 407 is fixedly and continuously provided at the top of the connecting cover 403. Several screen holes 408 are provided at the bottom of the screening tank 401, directly opposite the limiting frame 402, which can filter out solid impurities.
[0028] Please see Figure 2 A stirring assembly 5 is installed inside the screening tank 401. The stirring assembly 5 includes a rotating rod 501 rotatably installed inside the screening tank 401, a spiral guide plate 502 fixedly sleeved on the rotating rod 501, and several stirring rods 503 fixedly installed on the rotating rod 501.

The rotation of the rotating rod 501 drives the spiral guide plate 502 and several stirring rods 503 to rotate, thereby dispersing the sludge and discharging the filtered solid impurities.
[0029] The working principle of this utility model:
[0030] When sludge discharge is required, the sludge is first added into the inlet pipe 407, and the motor 504 is started, which drives the rotating rod 501 to rotate, causing the spiral guide plate 502 and several stirring rods 503 to rotate. This guides the sludge from the direction of the inlet pipe 407 to the direction of the outlet pipe 406. The stirring rods 503 can disperse the sludge. Since the bottom of the screening tank 401 is provided with a screen hole 408, the sludge enters the sludge discharge tank 1 through the screen hole 408. Solid impurities are filtered in the screening tank 401 and then guided to the outlet pipe 406 by the rotation of the spiral guide plate 502 and discharged. After the sludge enters the sludge discharge tank 1, it can be discharged from the sludge discharge pipe 2.
[0031] If it is necessary to adjust the height of the mud discharge pipe 2, two motors can be started at the same time, which can drive the corresponding threaded rods 303 to rotate, so that the support plate 301 moves on the support frame 302, thereby adjusting the height of the support assembly 3, and thus the height of the mud discharge pipe 2 is also adjusted.
[0032] If it is necessary to clean the inside of the device, the screening assembly 4 is first removed from the sludge channel 1, so that the limiting frame 402 is away from the sludge channel 1, then the screw nut 405 can be rotated, so that the screw nut 405 is removed from the screw rod 404, then the connecting cover 403 can be removed from the screening groove 401, so that the inside of the device can be opened, so as to clean the inside of the device.
[0033] The above describes the utility model and its implementation mode, this kind of description is not restrictive, the embodiment of the utility model shown in the drawing is only one, actual structure is not limited to this. In general, if the ordinary skilled person in the art is inspired, without departing from the utility model creation tenet, not creative design is similar to the structure mode and the embodiment of this technical solution, all should belong to the protection scope of the utility model.
