Novel screen plate with composite structure

Abstract

The invention relates to a novel screen plate with a composite structure. A compound screen surface and a metal screen bottom are integrally fixed, wherein the compound screen surface is arranged on the upper side, the metal screen bottom is arranged on the lower side, and the compound screen surface and the metal screen bottom are provided with corresponding screen holes. The screen surface is made of high-wear-resistant polyurethane materials, the service life of the screen plate is prolonged by more than 3-5 times, and the screen plate is light in specific weight, light in dead weight and obvious in energy-saving effect, and is economical and practicable. The screen bottom is made of metal materials, and the metal materials for the lower screen bottom only need to have proper bearing capacity and integral strength as frictional loss in use is borne by the upper screen surface. Therefore, materials for an original metal screen plate can be saved by 60%, the dead weight is reduced, energy is saved, and manufacturing cost is low. The novel screen plate is simple in manufacturing process, excellent in quality and reasonable in price, has obvious comprehensive advantages, realizes energy conservation and consumption reduction, and is uniformly well received by users after a large quantity of trial.

Description

technical field [0001] The invention relates to a sieve plate used for screening and sieving, in particular to a sieve plate that utilizes the combination of two or more materials and the characteristics of various materials to achieve wear resistance, corrosion resistance, low noise, impact resistance, New sieve deck with light weight composite material structure with excellent performance. Background technique [0002] The sieve plate is a key part used for screening and screening in some machinery, and its main purpose is the classification and separation of materials. At present, metal sieve plates and some non-metal sieve plates are widely used in grain processing, material crushing, mineral processing, coal, chemical industry, construction and other industries at home and abroad. The former has heavy weight, high consumables, and is easy to corrode and wear; energy consumption Disadvantages such as height and noise. The latter is improved compared with the former, bu...

AI Technical Summary

Problems solved by technology

At present, metal sieve plates and some non-metal sieve plates are widely used in grain processing, material crushing, mineral processing, coal, chemical industry, construction and other industries at home and abroad. The former has heavy weight, high consumables, and is easy to corrode and wear; energy consumption Disadvantages such as height and noise

The latter is improved compared with the former, but there are problems such as poor load resistance, low overall strength, and easy expansion and deformation.
