通水抵抗を低減化することが望まれている。However, the invention described in Japanese Patent Publication No. 35-9668 has a drawback of high water flow resistance. Therefore, Japanese Patent Application Laid-Open No. 8-33231
No. 6 and JP-A-9-38430, in order to reduce water flow resistance, a suction-molded support tube having a plurality of grooves along the cylinder direction is used, and at least the inner surface or outer surface of the cylindrical portion of the cartridge filter is used. It has been proposed to increase the surface area by providing a plurality of grooves along one cylinder direction. However, even with these, it is desired to further reduce water flow resistance.

実用化には至っていない。Therefore, in order to further increase the surface area,
It is easily conceivable to make the filter layer thinner, narrow the interval between the irregularities, and increase the number of irregularities. However, although this method can reduce the water flow resistance to a certain extent, the narrowing of the unevenness causes uneven lamination of the fibers in the concave portions, which causes a decrease in filtration accuracy. Also,
Because the filter layer is thin and the cross-sectional shape in the direction perpendicular to the cylinder direction is not circular, insufficient pressure resistance occurs during filtration,
It has not been put to practical use.

問題があった。In the invention described in Japanese Patent Publication No. 53-43709, there is proposed a cartridge filter having grooves on the inner and outer surfaces in a cylindrical direction, or a direction perpendicular to the cylindrical direction, or spirally. However, since the cartridge filter is manufactured by filling the gap between the inner cylinder and the outer cylinder having irregularities with the fiber containing the heat-fused fiber and heat-treating the same, the dense and dense layer caused by suction molding as in the present invention is used. And
A uniform filtration layer was not formed in each layer constituting the entire filtration layer, and thus there was a problem that the water flow resistance was high and the filtration life was short.

ルターである。SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention proposes a reinforced laminated filter cartridge having the following structure. That is, in a filtration cartridge filter manufactured by sucking the slurry liquid through a porous suction support tube, forming a laminate on the surface of the porous suction support tube, and then heat-curing the laminate to produce a cured product. By using a suction support tube in which concave and convex grooves are continuously formed in a direction perpendicular to the cylindrical direction, a laminate according to the concave and convex grooves is formed on the outer surface of the suction molded support tube, and the laminate is thermally cured. After that, there is provided a laminated filtration cartridge filter comprising a hollow cylindrical deep filter medium and a support, wherein the suction support tube is provided as a support while being integrated with the filter medium.

Further, the resistance to the pressure in the vertical direction at the time of filtration can be enhanced more than the conventional star or petal shape.

的である。In the present invention, as the slurry liquid for forming the laminate, inorganic fibers such as wood pulp and glass and chemical fibers such as acrylic and rayon can be used. In addition, a thermosetting resin such as a phenol resin, a melamine resin, or an epoxy resin, or a heat-fusible fiber can be added in order to enhance the filtration performance and the molding strength. Further, in order to further achieve low pressure loss and high filtration accuracy, it is more effective to add a resin such as polyamide epichlorohydrin or polyamine epichlorohydrin, which imparts adsorption ability by zeta potential.
