Large-flow composite filter element assembly

Abstract

The utility model provides a large-flow composite filter element assembly, and relates to the technical field of filter element assemblies, the large-flow composite filter element assembly comprises a tank body, an extension tank, a first drain valve and a second drain valve, one side of the top of the tank body is communicated with a liquid inlet pipe, and a filter mechanism is arranged in the tank body; sewage flows into the composite filter element through the liquid inlet pipe, impurities contained in the sewage can be intercepted in the composite filter element by the composite filter element, and water penetrates through the sieve pores of the composite filter element to enter the bottom of the tank body and is discharged to the outer side of the tank body through the first drain valve, so that the water is separated from the impurities, and the sewage is purified; a flocculating agent can be put into the composite filter element through the liquid inlet pipe, the self-locking motor drives the stirring rod to rotate on the inner side of the composite filter element through the rotating shaft, the stirring rod drives the flocculating agent to be mixed with water, impurities adhered to the composite filter element are gathered, the cleaning of the composite filter element is assisted, and the service life of the composite filter element is prolonged.
