Multistage flexible support screening machine

Abstract

The invention discloses a multi-stage flexible support screening machine, which comprises a frame, on which a filter sieve groove is installed horizontally, and on the frame is two A supporting beam, a flexible supporting spring is arranged between the supporting beam and the filter sieve; the frame is also provided with a vibration excitation mechanism for driving the vibration of the filter sieve; the filter sieve is equipped with There are at least two layers of sieves, and among the two adjacent layers of sieves, the sieve of the upper layer of sieve is larger than the sieve of the lower layer of sieve; An installation and fixing structure is provided corresponding to each layer of the screen mesh. The multi-stage flexible support screening machine of the present invention can not only meet the screening requirements of granular materials, but also can perform multi-stage screening at one time according to the granularity requirements, and has the advantages of high screening efficiency and low noise.

Description

technical field [0001] The invention relates to a screening machine, in particular to a multi-stage flexible support screening machine. Background technique [0002] The main purpose of the screening machine is to screen granular substances. It is applicable to a wide range of industries, such as: chemical industry, ceramics, food, electronic industry, etc. The screening machine is used to filter and screen the raw materials in advance to facilitate the next processing procedure. Therefore, the application of the screening machine can be described as quite extensive. Although the existing screening machines can meet the screening requirements of granular materials to a certain extent, they often have the problems of low screening efficiency and high vibration noise. In addition, most of the existing screening machines can only screen materials of one particle size at a time, and for the requirement of grading and screening according to the particle size, it is necessary to ...

Problems solved by technology

Although the existing screening machines can meet the screening requirements of granular materials to a certain extent, they often have the problems of low screening efficiency and high vibration noise.

In addition, most of the existing screening machines can only screen materials of one particle size at a time, and for the requirement of grading and screening according to the particle size, it is necessary to replace the sieve plate for multiple screenings, which is inefficient
