Polypropylene-microporous-membrane folded filter core

Abstract

The invention discloses a polypropylene-microporous-membrane folded filter core. The polypropylene-microporous-membrane folded filter core comprises two flat pressed openings, a shell, center rods, folded filter cores, flow guiding support layers and filter membranes, wherein the two flat pressed openings are formed in the two ends of the shell, the flow guiding support layers are arranged below the shell, the filter membranes are arranged below the flow guiding support layers, the center rods are arranged at the centers of the filter membranes, and the folded filter cores are arranged in the center rods. Membrane cores are placed in membrane piles, and water flow needing treatment is communicated, passes through one end of the two flat pressed openings, enters the flow guiding support layers from the shell, then, enters the center rods through the filter membranes and then flows out of the other end of the two flat pressed openings after folded filter membranes at the centers of the center rods operate repeatedly; the filter core is provided with micropores; the polypropylene-microporous-membrane folded filter core is made from polypropylene.

Description

technical field [0001] The invention relates to a filter core, in particular to a polypropylene microporous membrane folded filter core.
