AI Technical Summary

Technical Problem

The prior art is difficult to achieve uniform laying of the filter membrane in a large diameter powder-covered filter, resulting in poor filtration effect and degradation of equipment performance.

Method used

A large-diameter powder-covering filter including a water dispenser is designed. The water dispenser is composed of a water inlet distribution pipe and a multi-porous plate. The liquid is guided to the porous plate through the water inlet distribution pipe. The pore diameter on the porous plate is small, and the liquid diffuses evenly thereon, achieving uniform distribution of liquid and uniform laying of the filter membrane.

Benefits of technology

Through this design, the uniform laying of the filter membrane can be achieved in a large diameter filter, avoiding the defect of the filter element not being distributed in the edge area, and ensuring the quality of the effluent water quality.

Abstract

The utility model discloses a large-diameter powder covering filter, and particularly relates to the field of precision filtration, the large-diameter powder covering filter comprises a tank body, a filter element assembly and a water distributor, a water inlet pipe and a water outlet pipe are arranged at the bottom of the tank body, and the filter element assembly and the water distributor are arranged in the tank body; the water distributor comprises a water inlet distribution pipe and a porous plate; the water inlet distribution pipe is positioned in the middle of the filter element assembly and is coaxial with the water inlet pipe; the perforated plate is mounted at the top of the water inlet distribution pipe and is positioned above the filter element assembly; the periphery of the perforated plate is connected with the inner wall of the tank body. When liquid flows to the upper part of the perforated plate through the water inlet distribution pipe, the liquid is subjected to certain resistance when flowing out of the perforated plate due to relatively small apertures in the perforated plate, so that the liquid is promoted to be quickly diffused on the perforated plate, the liquid is uniformly distributed on the perforated plate, and then the liquid is downwards conveyed to the filter element assembly through the apertures in the perforated plate; the defect that feed liquid cannot be distributed to a filter element in an edge zone due to too large diameter of equipment can be avoided, and uniform film laying is ensured.
