Multistage flexible support screening machine

Abstract

The invention discloses a multistage flexible support screening machine. The machine comprises a frame; a filter screen groove is horizontally mounted on the frame; the frame is provided with two support cross beams respectively supported at two ends of the filter screen groove; flexible support springs are respectively arranged between the support cross beams and the filter screen groove; the frame is also provided with a vibration exciting mechanism for driving the filter screen groove to vibrate; at least two layers of filter screens are arranged in the filter screen groove; in two adjacent layers of filter screens, meshes of the upper layer of filter screen are larger than meshes of the lower layer of filter screen; and a mounting fixed structure is arranged in the filter screen groove corresponding to each layer of filter screen. The multistage flexible support screening machine not only can satisfy the screening requirements of granular substances, but also can once perform multistage screening according to the particle size 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
