Embodiment Construction

[0014] The sieve of the present invention can be made by winding a metal wire, metal strip, plastic strip or plastic wire into a compression spring type structure, and then processing the sieve hole 2 in the middle of the adjacent rib ring 1; It is also possible to set concave holes of the same specification on the corresponding two sides of a metal wire, metal strip, plastic strip or plastic wire respectively, and the distance between adjacent concave holes is equal, and then the metal wire, metal with concave holes Strips, plastic strips or plastic wires are wound into a compressed spring structure, and in the middle of adjacent rib rings 1, two concave holes can form a screen hole 2.

[0015] combine Figures 1 to 3 , the screen mesh of the present invention is made up of several rib rings 1, the ends and end tails of the two ends of the rib ring 1 are not connected, the ends and the end tails of the two ends are not on the same horizontal plane, the ends and end ends of th...

Abstract

The invention relates to a spring-type screen. The screen consists of at least three rib rings, wherein the heads and the tails of two ends of each rib ring are not positioned on the same horizontal plane; the head of the end of one of the other rib rings is connected with the tail of the end of an adjacent rib ring, except for the rib rings at two ends of the screen; and sieve meshes are formed between adjacent rib rings. Compared with a conventional screen, the screen disclosed by the invention has the greatest difference, namely the screen has the certain deformability. According to the screen disclosed by the invention, after the sieve mesh is blocked, only certain force is applied to the screen, so that a certain gap is formed between the two adjacent rib rings of the screen of a pressed spring type structure or the sieve meshes generate certain displacement, and attached stubborn attachments can be easily removed by matching with backwashing or scrubbing. Because the screen wholly deforms, the structure of the sieve meshes changes, so that the stable structure of the attachments is torn, and the screen can be easily cleaned.

Description

technical field [0001] The invention relates to a main part of a filter element, in particular to a screen of the filter element. Background technique [0002] There are many types of existing filter elements, but the overall structure of the filter elements is basically similar. Basically, screens with different precisions are set on a cavity, and the screens are also similar in composition, generally welded or welded. Fabricated mesh. These sieves have a common feature, that is, the mesh size of the sieve is fixed. When water is filtered, a layer of dirt is formed on the inner wall of the screen. Although most of the dirt can be removed by backwashing and brushing, as the use time increases, stubborn attachments will inevitably form on some meshes. Backwashing and brushing can no longer effectively remove it, and as time increases, the filtering effect of the entire screen will be greatly affected. Contents of the invention [0003] The technical problem to be solved...
