Through the mutual cooperation between multiple groups of structures, the utility model can drive the gear to rotate. The rotation of the gear drives the rotation of the first filtering chamber fixedly connected to the tooth groove belt. The rotation of the first filtering chamber causes the sewage to be thrown out from the mesh holes in the first filter screen, and the impurities are intercepted in the first filtering chamber. The intercepted impurities gather at the bottom of the first filtering chamber under the action of centrifugal force, and the impurities will not accumulate on the first filter screen to block the first filter screen. The setting of the first filtering chamber can effectively prevent the first filter screen from being blocked and facilitate the filtering of sewage.

[0003] In the prior art, during the sewage treatment process, workers often use filtering devices to treat sewage. However, after the internal filter layer of some existing filtering devices has been used for a long time, when workers need to regularly disassemble and replace it, they need to disassemble the entire filtering device. This process has many operation steps, is time-consuming and laborious, prolongs the disassembly time of the filter layer by workers, and is not convenient for workers to quickly disassemble and replace the filter layer inside the filtering device.

By controlling the connecting block 17, the limiting rod 18 can be indirectly driven to move inward until the limiting rod 18 moves out of the inside of the limiting hole 12, releasing the fixation of the fixing block 11. Subsequently, control the fixing block 11 to drive the baffle 9 and the sealing layer 8 to move out of the inside of the tank body 1, so that the baffle 9 releases the shielding of the filter layer 6, and then move it out of the inside of the limiting ring 5 to complete the disassembly of the filter layer 6. This process has fewer operating steps, saves time and effort, shortens the disassembly time of the filter layer 6 by the staff, and facilitates the staff to quickly disassemble and replace the filter layer 6 inside the device. A limiting rod 18 is fixedly connected to the outer side surface of the connecting block 17, the limiting rod 18 is movably inserted into the limiting hole 12, a short rod 19 is fixedly connected to the inner side surface of the moving block 15, and a return spring 20 is sleeved on the outer surface of the short rod 19.

[0026] In order to improve the connection stability between the water inlet pipe 3 and the tank body 1, a connection ring is fixedly sleeved on the right side of the outer surface of the water inlet pipe 3, and the right side surface of the connection ring is fixedly connected to the outer surface of the tank body 1. The connection ring increases the connection area between the water inlet pipe 3 and the tank body 1 and improves the connection stability between the water inlet pipe 3 and the tank body 1.

[0027] In order to extend the service life of the two groups of return springs 20, the number of the return springs 20 is set to two groups. The manufacturing materials of the two groups of return springs 20 are both set to silicon manganese spring steel.

Stainless steel has a high hardness and is not easy to deform, ensuring that the fixing block 11, the moving block 15, the limiting block 16, the connecting block 17, the limiting rod 18 and the short rod 19 are not easily damaged during use.

[0031] The electrical components appearing in this text are all electrically connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device such as a computer for control.

[0032] During use, sewage enters the interior of the tank body 1 through the water inlet pipe 3. Subsequently, the sewage passes through the two groups of filter layers 6 from top to bottom. At the same time, the filter layer 6 can effectively filter the sewage, intercepting the impurities in the sewage above the filter layer 6. Then, the filtered sewage is discharged through the water outlet pipe 4. Thus, the filtration of the sewage begins. When the staff needs to replace the filter layer 6, the staff controls the connecting block 17 to drive the moving block 15 and the limiting block 16 to move inward along the inside of the sliding groove 13 and the limiting groove 14 respectively. At the same time, the connecting block 17 drives the limiting rod 18 to move inward, causing the moving block 15 to drive the short rod 19 to move inward to squeeze the return spring 20 until the limiting rod 18 moves out of the inside of the limiting hole 12, releasing the fixation of the fixed block 11. Subsequently, the fixed block 11 is controlled to drive the baffle 9 and the sealing layer 8 to move forward out of the interior of the tank body 1. At the same time, the baffle 9 drives the insertion rod 10 to move out of the inside of the insertion hole 7, causing the baffle 9 to release the shielding of the filter layer 6. Then, the filter layer 6 is moved forward out of the inside of the limiting ring 5. Thus, the disassembly of the filter layer 6 is completed. Conversely, the staff can install a new filter layer 6. Thus, the replacement of the filter layer 6 is completed.
