Filtering lamination and lamination type filter comprising same

Abstract

The present invention relates to a filter laminate comprising: a laminate body which is an annular sheet-like body; a first-stage filtering bulges and a second-stage filtering bulges, which are arranged on the upper surface of the lamination body, wherein the first-stage filtering bulges and the second-stage filtering bulges are arranged at intervals from outside to inside in the radial direction;first-stage filtering grooves and second-stage filtering grooves, which are arranged on the lower surface of the lamination body, and the first-stage filtering grooves and the second-stage filteringgrooves are arranged at intervals from outside to inside in the radial direction; and the positions of the first-stage filtering grooves and the second-stage filtering grooves respectively correspondto the positions of the first-stage filtering bulges and the second-stage filtering bulges on the upper surface of the lamination body. The invention also relates to a laminated filter comprising a plurality of filter laminations stacked together in alignment. According to the filter lamination and the laminated filter, two-stage filtration is realized, the structure is simple, the filtering effect is good, and the filtering efficiency is high.

Description

technical field [0001] The invention relates to a filter laminate and a filter device, in particular to a filter laminate and a laminate filter. Background technique [0002] The laminated filter is used to filter the liquid containing impurities. It can filter out impurities such as sediment, rust, microorganisms, suspended solids, colloids, etc. It is mainly used in chemical, petrochemical, smelting, pharmaceutical, food, irrigation and other industries. [0003] The laminated filter mainly includes components such as a shell, laminated sheets, and laminated brackets, among which the laminated sheet is the most important part of the laminated filter. The structure of the laminations plays a decisive role in the filtering effect. [0004] The laminations in the existing lamination filters are filtered through the filter channels provided on the laminations, see for example Chinese Patent Application Publication No. CN107777741A. The size of the filter channel determines t...
