[0024] Through the rotary filtering structure, the rotating turntable 405 is used to drive the transmission rod 401 to rotate, so that the physical filter screen 402 installed on the outer side of the transmission rod 401 rotates synchronously, and the auger-type physical filter screen 402 that continuously rotates upward rotates in the opposite direction to the liquid to be filtered flowing down from the top. The liquid to be filtered is input through the water inlet top plate 3 at the top, and can be processed by the unfolded buckle plate 301 or the water inlet port 302 so that the liquid to be filtered enters the primary filter cartridge body 1. The rotational force generated when the physical filter screen 402 is driven to rotate can buffer the falling flow rate of the liquid to be filtered, prolong its duration on the filter screen, and improve the filtering efficiency. The upper and lower multiple layers of the physical filter screen 402, as well as the filter cotton and fiber ball filter materials that constitute the physical filter screen 402, also ensure the filtering effect well.

[0025] The filtered water after deep filtration will enter the precision filter cartridge, and the nanofiltration membrane layer inside it will be used to perform the final deep filtration treatment on the filtered water to ensure that the filtered water meets the filtration standards and is easy to recycle.

[0026] Working principle: For this type of sewage deceleration and filtering device, firstly, the transmission pipe of the washing water to be filtered is connected to the water inlet port 302 at the top of the water inlet top plate 3, and the washing water to be filtered will contact the physical filter screen 402. As part of the water passes through the physical filter screen 402 and enters the physical filter screen 402 of the next layer, the remaining washing water will flow gradually downward along the slope of the physical filter screen 402, and the filtering process will be continuously carried out during the flow. The filtered impurities will remain on the surface of the physical filter screen 402, or be adsorbed in the inner layer of the physical filter screen 402, and will be filtered. During the operation, by starting the rotating turntable 405, the transmission rod 401 can be driven to cause the physical filter net 402 on its outer side to rotate upward, forming a torque force to transport the water upward, thereby alleviating the downward flow rate of the water to be filtered and extending its duration on the filter net. The filtered water will gather at the bottom of the primary filter cartridge body 1 and be transported to the precision filter cartridge body 2 through the water inlet pipe 201 for the final filtration treatment. After the multi-layer filtration treatment in the precision filter cartridge body 2, the filtered water can be recovered from the drain pipe 202 at the bottom of the precision filter cartridge body 2.

Any changes or substitutions that can be thought of by any technician familiar with the field within the technical scope disclosed by the utility model without creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
