Cylindrical cartridge filter with improved filtering capacity

摘要

Cylindrical cartridge filter of the present invention is a filter with improved filtration capability, and when the synthetic resin melted, extruded, and spun by an extruder is wound into the winding rod in the form of a nonwoven fabric, the irregular groove is simultaneously formed by the shape groove provided in the shape roller do.;The cartridge filter thus manufactured has a uniform pore inside which determines the degree of filtration, and the portion pressed by the protrusion of the shape roller improves the adhesion state of the spun resin to maintain the mechanical strength of the cartridge filter. The cylindrical shape of the cylindrical roller has improved filtration capability by increasing the holding capacity of the cartridge filter by forming a portion formed by the recessed portion of the shape roller while increasing the filtration surface area and making the density smaller than the inside. It is about a filter.;Cylindrical cartridge filter manufactured in this way does not require a separate lathe machining or additional cost to form a concave-convex groove at the same time of molding and improve the filtration capacity, and also prevent the destruction of the fibrous material by preventing the destruction of the fibrous structure, The mechanical strength peculiar to the resin, which is a material, is maintained, and production and production cost reductions are achieved, which is economical.
