Standard rail chair type elastic rod sieve plate

Abstract

The invention discloses a standard rail chair type elastic rod sieve plate which comprises rail chairs and an elastic sieve surface. The elastic sieve surface comprises a sieve frame, an elastic support body and sieve rods, the elastic support body is fixed in a containing body of the sieve frame, the two ends of each sieve rod are fixed in the elastic support body, and the elastic sieve surface is connected with the rail chairs through buckle devices. According to the standard rail chair type elastic rod sieve plate, the elastic support body can enable the sieve rods to be located in a resonant state in the working process of a vibrating sieve, the vibration intensity of the sieve surface is improved, and by means of the autoroatation and movement in the axial direction of the sieve rods, the problems of material stacking, bonding and mesh blocking are well solved, and the screening efficiency of the vibrating sieve is improved; due to the fact that the rail chairs are connected with the elastic sieve surface through the buckle devices, the structure is compact, assembly and disassembly are convenient, the practicability is strong, and the labor intensity of workers is reduced; according to the standard rail chair type elastic rod sieve plate, the modular design is adopted, and scale production and market promotion are facilitated.

Description

Technical field [0001] The invention relates to the field of vibrating screening machinery, in particular to a standard rail seat type elastic rod screen plate, which is suitable for various large-scale vibrating screens or vibrating screens for screening viscous and wet materials. Background technique [0002] An ideal material is screened under normal conditions, and the screening efficiency is generally required to reach 96%, which means that 96% of the particles with a particle size smaller than the specified screening size pass through the sieve holes on the screen. However, because the vibrating screen realizes the screening of materials through the vibration of the screen surface, there are the following problems in the screening process: Considering the influence of the rigidity and strength of the screen body itself, the vibration intensity is generally maintained in a relatively low interval (3~ 5g). The traditional sieve plate only moves rigidly with the sieve body wit...

AI Technical Summary

Problems solved by technology

However, since the vibrating screen realizes material screening through the vibration of the screen surface, there are the following problems in the screening process: Considering the influence of factors such as the stiffness and strength of the screen body itself, the vibration intensity is generally kept at a low interval (3~ 5g), the traditional sieve plate only moves with the sieve body as a rigid body, and has no additional movement itself. At the same time, because of the uneven material and uneven humidity of the material, these reasons will affect the rapid layering and sieving of the material, and even cause piles. The problem of material and hole plugging seriously affects the screening efficiency

By increasing the vibration strength of the sieve plate, it puts forward high requirements on the structural strength of the sieve body, resulting in high production cost of the screening equipment; using a chain or ball cleaning device, although the cleaning of the screen surface can be completed to a certain extent , but it is easy to cause chain wear and tear and frequent drop of the ball disc, resulting in the danger of downtime
