The slide groove 43 functions as a limit function, so that the two sand-stone filter cartridges 5 can be rotated conveniently.

The working principle is as follows:

the effluent of the waste water pipe 1 is beaten on the dispersion plate 18, so that the waste water is dispersed and beaten on the conical filter screen 14, under the action of the shape of the conical filter screen 14, the waste water moves downwards along the inner wall of the conical filter screen 14, the conical filter screen 14 separates impurities and water, the impurities remained on the inner wall of the conical filter screen 14 enter the waste pipe 16 through the slag discharge hole 19 under the action of water flow and finally flow into the waste collection box, the water separated by the conical filter screen 14 enters the screen filter barrel 13 and is guided onto the rotary wheel 34 through the water guide pipe 15, the rotary wheel 34 is driven to rotate and then enters the sand filter barrel 5 through the water inlet 32 for filtering, the filtered clear water is guided into the culture pond through the clear water outlet pipe 21, the rotary wheel 34 rotates to drive the first rotary shaft 33 and the first gear 35 to rotate, under the action of the chain 39, the second gear 38 drives the cam 37 to rotate, when the cam 37 contacts the cover plate 28, the cover plate 28 drives the long rod 29 to move downwards, when the cam 37 does not contact the cover plate 28, the cover plate 28 is reset under the action of the compression spring 31, the cover plate 28 drives the stirring rod 30 to stir the quartz sandstone layer 40, clean water in the water supply tank 27 enters the sandstone filtration cylinder 5 through the clean water inlet pipe 26, and wastewater obtained by cleaning the quartz sandstone layer 40 is guided into the wastewater collection tank 25 through the wastewater outlet pipe 24.

After treatment facility operation a period, start driving motor 8, driving motor 8 drives bull stick 10 and rotates, thereby bull stick 10 drives rotor plate 11 and drives two grit cartridge filter 5 rotations for the transform takes place for the position of two grit cartridge filter 5.
