A multi-degree-of-freedom rotatable vibrating screening device

Abstract

The invention discloses a multi-degree-of-freedom rotatable vibration screening device. The multi-degree-of-freedom rotatable vibration screening device comprises a base device, a vibration device I,a vibration device II, a collection device, a rotating screen device and a controller, wherein the controller is used for controlling starting, stopping and operation of the entire device; the vibration device I is mounted on the base device and is used for providing a plane degree of freedom; the vibration device II is mounted on the vibration device I and is used for providing a plane degree offreedom; the rotating screen device is mounted on the vibration device II and provides a space rotation degree of freedom; and the collection device is mounted on the base device, and is used for collecting screened materials and separated impurities after screening. According to the multi-degree-of-freedom rotatable vibration screening device, multi-degree-of-freedom vibration can be achieved, screening efficiency is improved, the uniformity degree of screening can be effectively improved through the rotating screen device, and meshes of the screen are prevented from being blocked.

Description

technical field [0001] The invention belongs to the technical field of vibration screening machinery, in particular to a multi-degree-of-freedom rotatable vibration screening device. Background technique [0002] Screening machinery is widely used in many industries such as coal, metallurgy, mining, chemical industry, food, etc. The current screening operation equipment uses the relative movement between bulk materials and the screen surface to make some particles pass through the screen holes, and sand, gravel, etc. Materials such as gravel and gravel are divided into different levels of vibrating screening machinery and equipment according to particle size. The particle level of sieving depends on the sieve surface, and the sieve surface is divided into three types: grate, plate sieve and mesh sieve. The grate is suitable for sieving large-grained materials, and the gap between the grate is 1.1 to 1.2 times the particle size of the underscreen, generally not less than 50m...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the mainstream screening devices on the market are mainly vibrating screens, supplemented by fixed screens; but as far as the existing vibrating screens are concerned, there is still a large room for improvement in vibration efficiency, so it is necessary to invent a stable A multi-degree-of-freedom rotatable vibrating screening device with the advantages of reliability, low consumption, low noise, long life, stable vibration shape, and high screening efficiency
