[0029] Specifically, two support plates 210 are fixedly mounted on the surface of the base 1, and an electric telescopic rod 211 is fixedly mounted on the surface of the support plate 210, and the output end of the electric telescopic rod 211 is fixedly connected to the movable block 208. The setting of the electric telescopic rod 211 has the effect of driving the movable block 208 to move inside the slide groove 207.

[0030] In this embodiment: a diversion device 3 is provided on the inner wall surface of one side of the filter tower body 5, and the diversion device 3 includes two round rods 301, and the two round rods 301 are fixedly installed on the inner wall surface of one side of the filter tower body 5, and a diversion box 302 is fixedly installed on the end surface of the two round rods 301 away from the filter tower body 5. When the device needs to be used, first open the sealing door 6, and then rotate the rotating wheel 308. The rotation of the rotating wheel 308 drives the threaded rod 307 to rotate. The rotation of the threaded rod 307 drives the movable plate 310 to move inside the groove 309. The movable plate 310 moves inside the groove 309 and drives the connecting rod 311 to move. The connecting rod 311 moves and drives the baffle 305 to move upward inside the vertical groove 304.

The two electric telescopic rods 211 are started to drive the two movable blocks 208 to move away from each other inside the slide groove 207. The two movable blocks 208 move away from each other inside the slide groove 207 to drive the hinged plate 209 to move. The hinged plate 209 moves and pulls the tower bottom 203 to move downward. The downward movement of the tower bottom 203 drives the slide plate 202 to move downward on the surface of the U-shaped rod 201. At the same time, the downward movement of the tower bottom 203 also separates itself from the filter tower body 5. At this time, under the separation effect of the filter tower body 5 and the tower bottom 203, it is convenient to clean the remaining debris inside the tower bottom 203 and reduce the occurrence of sedimentation. Through the cooperation of the above-mentioned structure, the purpose of cleaning the device is achieved, the occurrence of bottom sedimentation is reduced, and the treatment effect when it is used again is guaranteed. When the device needs to be used, first open the sealing door 6, and then rotate the rotating wheel 308. The rotation of the rotating wheel 308 drives the threaded rod 307 to rotate. The rotation of the threaded rod 307 drives the movable plate 310 to move inside the groove 309. The movable plate 310 moves inside the groove 309 and drives the connecting rod 311 to move. The connecting rod 311 moves and drives the baffle 305 to move upward inside the vertical groove 304. When the baffle 305 moves upward inside the vertical groove 304 to a suitable height, stop rotating the rotating wheel 308, and then close the sealing door 6. Then, the sewage is introduced into the separation box through the water inlet pipe 7. At this time, the incoming sewage can be diverted and flow into the filter screen 8 under the action of the notches 303 on the four sides of the separation box. The sewage is effectively treated by filtering through the filter screen 8. Through the cooperation of the above-mentioned structure, the incoming sewage can be diverted and flow into the filter screen 8 to avoid damage to the filter screen 8 due to excessive impact force.
