Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention will be further described:

[0012] 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.

[0013] 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, t...

Abstract

The invention relates to a spring-loaded screen. The spring-loaded screen is characterized by comprising at least three ribbed rings. The tip and tail at the two ends of each ribbed ring are not located on the same horizontal plane. Except for the ribbed rings at the two ends of the screen, the tip of one of the rest of the ribbed rings is connected with the tail of the ribbed ring adjacent to the former ribbed ring, and screen holes are formed between the adjacent ribbed rings. Due to the fact that the sizes of the screen holes of an existing screen differ very much according to different screening grades, the diameter of the screen holes is only dozens of micrometers particularly for high-precision screening, the screen holes of the structure are most likely to be blocked and cannot be easily cleaned, the screen holes are difficultly and thoroughly cleaned even after the screen is detached, and the biggest difference between the spring-loaded screen and the existing screen is that the spring-loaded screen has the certain deformation capability.

Description

technical field [0001] The invention relates to a spring screen. 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] Aiming at the problems existing in the prior art, the object of the present invention is to provide...
