Filtering screen with adjustable screen hole mesh number

Abstract

The invention discloses a filtering screen with the adjustable screen hole mesh number, and belongs to the field of a filtering screen. In order to solve the problem that the existing filtering screenmesh number cannot change after the production completion, the quantity of the filtering screens used in the filtering is reduced; the filtering process is simplified. The filtering screen with the adjustable screen hole mesh number comprises a screen frame, screen wires arranged on the screen frame, two slide ways parallelly arranged on the screen frame, first slide strips arranged on the slideways, second slide strips arranged on the slide ways, upright posts arranged on the first slide strips and the second slide strips and wire passing balls arranged at the end part of the upright posts,wherein wire passing holes are formed in wire passing balls. The problem that the existing filtering screen mesh number cannot change after the production completion is solved; the mesh number can bechanged according to the filtering requirements; the effect of multipurpose of one screen is achieved; the number of filtering screens used in the filtering process is reduced; the filtering processis simplified.

Description

technical field [0001] The invention belongs to the technical field of filter nets, and relates to a filter net, in particular to a filter net with an adjustable mesh number. Background technique [0002] The filter screen is referred to as the filter screen, which is processed by different mesh meshes. Its function is to filter the molten material flow and increase the resistance of the material flow, so as to filter out mechanical impurities and improve the effect of mixing or plasticizing. [0003] It has the properties of acid resistance, alkali resistance, temperature resistance and wear resistance; it is mainly used in mining, petroleum, chemical, food, medicine, machinery manufacturing and other industries. The filter screen is divided into textile fiber filter screen and metal filter screen. A machine with a filter installed is called a filter and is used to filter natural water and food. [0004] The mesh size of the existing filter mesh cannot be changed after th...
