When the resistance slider 32 moves up along the conductive slider 31, the current of the power supply circuit of the third motor 33 will decrease, which will reduce the power supply current of the third motor 33 and the speed of the third motor 33.

[0039] The linkage mechanism includes a connecting plate 37 fixedly connected to the side wall of the sleeve rod 10, and the connecting plate 37 is sleeved on the outer side of the vertical pipe 22.

When the pressure touch switch 34 contacts the extrusion block 36, the pressure touch switch 34 is triggered and the second motor 28 starts.

[0040] When the present invention is used, the aquaculture sewage is introduced into the interception box 4 through the feed hopper 6, the first motor 5 is started, the belt roller 45 is driven to rotate, and the conveyor belt 12 is driven to rotate through the belt roller 45. The conveyor belts 12 are arranged at intervals, and the larger impurities in the aquaculture sewage are first intercepted by the conveyor belt 12, and the larger impurities can be directly transported by the movement of the conveyor belt 12, so that the larger impurities directly fall into the slag discharge box 3 for discharge, thereby effectively reducing the load pressure of subsequent sewage filtration;

[0041] The intercepted sewage will enter the filter cylinder 25 through the second telescopic tube 23, and the smaller impurities in the sewage can be filtered through the flexible filter 39. The filtered sewage will flow down to the sedimentation tank 1, and the flocculant will be added to the sedimentation tank 1 through the flocculant adding tube 46, and then the third motor 33 will be started to drive the rotating rod 42 to rotate, and the rotating rod 42 will drive the stirring rod 43 to rotate, and the stirring rod 43 will stir the flocculant and the sewage to mix more fully;

[0042] As the amount of sewage in the sedimentation tank 1 increases, the floating plate 44 moves upward due to the buoyancy of the sewage, thereby driving the sleeve rod 10 to move upward, and the stirring rod 43 can move upward while stirring. When the sleeve rod 10 moves upward, it can drive the resistance slider 32 to move upward along the conductive slider 31, thereby increasing the resistance, reducing the power supply current of the third motor 33, and reducing the speed of the third motor 33. During the upward movement of the sleeve rod 10, the speed of the stirring rod 43 will slow down, which can reduce the damage to the flocculent body and improve the flocculation effect.

[0043] When the sleeve rod 10 moves upward, it will drive the connecting plate 37 to move upward, thereby compressing the second spring 21. Due to the magnetic attraction of the scraper 24 and the magnetic rotating sleeve 38, the scraper 24 and the vertical pipe 22 will not move upward at this time. When the amount of sewage in the sedimentation tank 1 rises and reaches a preset amount, that is, when the connecting plate 37 moves up to the limit position, the third motor 33 is turned off. At this time, the pressure touch switch 34 contacts the extrusion block 36, the pressure touch switch 34 is triggered, and the second motor 28 is started to drive the vertical pipe 22 to rotate, and then the electric telescopic rod 13 is started to extend, driving the baffle 14 to rotate and close, so that sewage is no longer fed, and at the same time, the elastic force of the second spring 21 breaks through the adsorption force of the scraper 24 and the magnetic rotating sleeve 38, and then the second spring 21 is extended to drive the vertical pipe 22 to move upward. When the vertical pipe 22 moves upward, it drives the scraper 24 to move upward and flips the flexible filter screen 39 upward to the top of the filter cylinder 25. The rotation of the vertical pipe 22 can drive the flexible filter screen 39 to rotate , and during the extension of the second spring 21, the first spring 16 will be compressed. When the second spring 21 is fully extended, that is, when the vertical pipe 22 moves up to the limit position, the block 27 blocks the lower end of the filter cylinder 25, thereby forming a closed space between the flexible filter screen 39 and the lower end of the filter cylinder 25, and at the same time, the elastic force of the compressed first spring 16 breaks through the magnetic attraction force of the sliding plug 41 and the magnetic ring 47, and the sliding plug 41 moves up inside the sliding plug cylinder 7, thereby squeezing the space inside the sliding plug cylinder 7, so that the gas inside the sliding plug cylinder 7 is squeezed into the vertical pipe 22 through the first telescopic tube 15 and the rotary joint 17, and reversely blows air from the inner side of the flexible filter screen 39 through the one-way air nozzle 40, so that impurities adhering to the flexible filter screen 39 are easier to detach. At the same time, when the flexible filter screen 39 rotates, the impurities can be thrown away from the flexible filter screen 39 by the action of centrifugal force, thereby realizing automatic cleaning of the flexible filter screen 39, and the cleaned impurities are discharged from the filter box 2 through the slag discharge box 3;

[0044] Then the sewage in the sedimentation tank 1 is discharged through the sewage pipe 11. When the amount of sewage decreases, the sleeve rod 10 moves down and resets, and the connecting plate 37 can drive the vertical pipe 22, the scraper 24, the flexible filter 39, the sliding plug 41 and other components to move down and reset.

[0048] S3, the sewage enters the sedimentation tank 1 and undergoes flocculation and sedimentation treatment

[0049] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto.
