[0020] The filter paper conveying and applying structure 2 includes a rectangular placing table 2-1, a supporting groove 2-2 is provided on the side of the rectangular placing table 2-1 close to the first rotating motor 1-6, a filter paper placing rack 2-3 is extended on the side away from the supporting groove 2-2, a cutting mechanism 3 is provided between the supporting groove 2-2 and the filter paper placing rack 2-3, a hollow rectangular sliding rack 2-5 is provided above the rectangular placing table 2-1, and a second screw parallel to the long side of the rectangular sliding rack 2-5 is installed in the middle of the hollow rectangular sliding rack 2-5 The second threaded rod 2-6 has one end connected to a second rotating motor 2-7, and a movable suspension rod 2-8 penetrated by the second screw rod 2-6 is also slidably installed on the rectangular sliding frame 2-5, and the movable suspension rod 2-8 includes two third threaded rods 2-9 which are perpendicular to the rectangular placing platform 2-1 and distributed on both sides of the second threaded rod 2-6, and the lower ends of the third threaded rods 2-9 are fixedly connected with a pneumatic adsorption device 2-10, and the upper ends of the third threaded rods 2-9 are respectively connected with third rotating motors 2-11.

[0021] Furthermore, the water outlet baffle 1-1, the filter cylinder 1-2 and the filter element 1-3 are provided with filter holes in an array, the filter holes on the filter cylinder 1-2 are 1.2-1.5 times the number of the filter element 1-3, and the filter holes on the water outlet baffle 1-1 are 8-10 times the number of the filter element 1-3.

[0022] Furthermore, the cutting mechanism 3 comprises a knife receiving groove 3-1, a driving cylinder 3-2 is installed on the inner bottom surface of the knife receiving groove 3-1, and a cutting knife 3-3 is connected to the driving shaft of the driving cylinder 3-2.

[0023] Furthermore, a water level sensing device is provided at the bottom of the return water tank 1, and a photosensor is provided inside the filter cylinder.

[0024] Furthermore, a water-leakage-proof rubber ring 1-4-1 is provided on the sealing cover 1-4.

[0025] The working principle of the utility model is as follows: polluted water enters the return water tank 1 from the water inlet, and after passing through the filter cylinder 1-2, the pollutants adhere to the filter paper and the filter cylinder 1-2, and the treated water flows into the recovery water storage device through the water outlet baffle 1-1. When the sensor in the filter cylinder 1-2 senses a certain thickness of the pollutant accumulation layer, the water inlet is controlled to stop water intake. After the treated water in the return water tank 1 flows into the water storage device, when the water level sensing device at the bottom of the return water tank 1 detects that the water level is low, the telescopic cylinder 1-5 is driven to make the filter element 1-3 move horizontally out of the filter cylinder 1-2 and be placed at the support groove 2-2 of the rectangular placement table 2-1.

At this time, the pressure inside the air pressure adsorption device 2-10 is reduced so that the filter paper can be adsorbed on the air pressure adsorption device 2-10, and then the second rotating motor 2-7 operates in the opposite direction to make the movable boom 2-8 move horizontally with the filter paper to the top of the filter element 1-3, and drive the third rotating motor 2-11 to make the air pressure adsorption device 2-10 descend until it is attached to the surface of the filter element 1-3, and drive the cylinder 3-2 to drive the cutting knife 3-3 to rise and cut the filter paper, and then the internal pressure of the air pressure adsorption device 2-10 is increased to be flush with the outside world, and the adsorption force disappears. Since the filter element 1-3 is wet, the filter paper is adsorbed on the surface of the filter element 1-3 by the adsorption force of water. At this time, the first rotating motor 1-6 is driven to make the filter element 1-3 rotate itself, and the filter paper also rotates and adheres to the surface of the filter element 1-3. Then the air pressure adsorption device 2-10 leaves the filter element 1-3, and the telescopic cylinder 1-5 works to move the filter element 1-3 back into the filter cylinder 1-2, and the filter paper replacement work is immediately completed.
