[0039] In this embodiment, when in use, the external power supply is turned on, and the sewage to be filtered is poured from the opening at the top of the shell 1. The sewage will pass through the two groups of guide plates 7 in sequence. The gap between the group of guide plates 7 near the top of the shell 1 is wider, and the gap between the group of guide plates 7 near the bottom of the shell 1 is narrower, which is convenient for filtering debris of different volumes. The filtered debris slides from the guide plates 7 to the inside of the temporary storage box 3 under the action of gravity. Whenever debris falls on the guide plates 7, the impact force will be transmitted to the two groups of mounting rods 6 and the elastic member 10. The elastic member 10 is forced to be compressed and rebound after compression, so that the guide plate 7 vibrates to prevent debris from staying on the guide plate 7. The debris in the temporary storage box 3 is piled on the bearing rod 301. The bottom of the temporary storage box 3 is connected to the filter tube 2, and the gap between the bearing rods 301 is small, which is convenient for leaking sewage on the debris into the filter tube 2. The staff controls the two electric push rods 5 to work, pushes the sealing door 4 to drive the sealing ring 9 to rotate on the shell 1, so as to open the temporary storage box 3 and centrally clean the debris from the bearing rod 301.

The round beads 204 are made of activated carbon. The sediment accumulation height inside the sedimentation box 210 is observed through the transparent plate 203. The threaded rod 209 is rotated to drive the baffle plate 201 to retract the filter tube 2, and the filter tube 2 and the sedimentation box 210 are blocked. The baffle plate 201 squeezes the sealing gasket 208, which greatly reduces the gap between the two. The electromagnet 207 is closed, and the electromagnet 207 no longer adsorbs one end of the sealing plate 205. Then the sealing plate 205 is opened. When the sealing plate 205 is opened, it drives the sealing ring 206 to leave the sedimentation box 210, so that the staff can centrally clean the sediment inside the sedimentation box 210. At the same time, the filter tube 2 can still continue to filter sewage, which is beneficial to improve the working efficiency of the filtering device.

The gap between the guide plates 7 near the top of the shell 1 is wider, and the gap between the guide plates 7 near the bottom of the shell 1 is narrower, which is convenient for filtering debris of different volumes. The filtered debris slides from the guide plates 7 to the inside of the temporary storage box 3 under the action of gravity. Whenever debris falls on the guide plates 7, the impact force will be transmitted to the two groups of mounting rods 6 and the elastic member 10, forcing the elastic member 10 to be compressed and rebound after compression, so that the guide plates 7 vibrate to prevent the debris from staying on the guide plates 7. The debris in the temporary storage box 3 is piled on the bearing rod 301 through the pulley. The bottom of the temporary storage box 3 is connected to the filter tube 2, and the gap between the bearing rods 301 is small, which is convenient for leaking the sewage on the debris into the filter tube 2.

When in use, the sewage is discharged after passing through the filter screen 202 and the round ball 204 inside the filter tube 2. The round ball 204 is made of activated carbon. The sediment accumulation height inside the sedimentation box 210 is observed through the transparent plate 203. The threaded rod 209 is rotated to drive the baffle plate 201 to retract the filter tube 2, and the filter tube 2 and the sedimentation box 210 are blocked. The baffle plate 201 squeezes the sealing gasket 208, which greatly reduces the gap between the two, and closes the electromagnet 2 07, the electromagnet 207 no longer adsorbs one end of the sealing plate 205, and then opens the sealing plate 205. When the sealing plate 205 is opened, it drives the sealing ring 206 to leave the sedimentation box 210, so that the staff can centrally clean the sediment inside the sedimentation box 210. At the same time, the filter tube 2 can still continue to filter sewage, which is beneficial to improve the working efficiency of the filtering device.
