The rotating shaft 3 is driven to rotate by the motor 202, and the rotating shaft 3 simultaneously drives the spiral conveying blades 301 and the conical spiral conveying blades 302 to rotate. After the impurities are preliminarily filtered through the semicircular water filter net 203 at the lower end of the filter device 2, the spiral conveying blades 301 convey the filtered impurities to the inside of the conical filter press 4, and the impurities are conveyed to the circular tube 402 through the conical spiral conveying blades 302.
