Problems solved by technology

[0002] Generally speaking, metal screens are often used in filtration, refining, screening and other processes in many fields such as chemical industry, food, plastic manufacturing, mining and metallurgy, etc., which can quickly separate solid particles according to the pore size. There are two main types of screens: one is a plate-shaped screen formed by drilling or punching on a metal plate structure, but this plate-shaped screen has a solid metal structure between holes and solid materials It is easy to block when passing through,

Embodiment Construction

[0012] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0013] see figure 1 , figure 2 The long-life high wear-resistant screen and the traditional screen both include the sieve column 2 and the screen frame 1. figure 1 In the long-life and high wear-resistant screen structure, there is a cylindrical structure with a length L on the upper part of the screen column 2, and its equal width gap is h. The wear of the screen during use, as long as the wear does not exceed L, the screen Keeping the mesh gap h unchanged can ensure the normal use of the screen.

[0014] figure 2 It is a screen structure widely used at present, and the screen gap is h. When the screen is worn out during use, the screen gap will gradually expand, thus losing its use value.

[0015] The basic principles, main features and ...

Abstract

The invention discloses a high wear-resistant screen with a long service life, which comprises screen columns and a screen frame, wherein the screen columns are processed by using a milling cutter and a special-shaped die and a way of laser cutting or linear cutting and are uniformly fixed on the screen frame to form gaps with equal widths, meanwhile the each screen column comprises two parts, wherein the upper part is a column-shaped structure with uniform upper and lower surfaces; and the lower part is a wedge-shaped structure with narrow bottom and wide top. The high wear-resistant screen with long service life is simple and convenient for process; the screening efficiency can be improved in the condition of guaranteeing the screening quality; and the service life of the screen can be prolonged effectively at the same time.

Description

technical field [0001] The invention relates to a wear-resistant screen, in particular to a long-life and highly wear-resistant screen used for intercepting solid phases in the solid-liquid separation process. Background technique [0002] Generally speaking, metal screens are often used in filtration, refining, screening and other processes in many fields such as chemical industry, food, plastic manufacturing, mining and metallurgy, etc., which can quickly separate solid particles according to the pore size. There are two main types of screens: one is a plate-shaped screen formed by drilling or punching on a metal plate structure, but this plate-shaped screen has a solid metal structure between holes and solid materials It is easy to block when passing through, and the screening efficiency per unit time is low; therefore, another mesh type screen is used in the usual processing process. However, after using this screen for a period of time, the middle part of the screen...
