Particle material classification sorting device

Abstract

The invention relates to a particle material classification sorting device. The particle material classification sorting device consists of a screening box, an upper sieve plate, a lower sieve plate, spring vibrators and a console. The screening box is in a cuboid shape and formed by welding steel plates; the upper sieve plate is obliquely installed inside the screening box, and sieve holes are uniformly distributed in the upper sieve plate; the inclination direction of the lower sieve plate is opposite to that of the upper sieve plate in installation, and the diameter of each sieve hole of the lower sieve plate is smaller than that of each sieve hole of the upper sieve plate so as to realize a classification sorting effect; the spring vibrators are arranged on the bottom of the screening box and used for controlling the entire screening box to move up and down in a reciprocating manner so as to enhance the screening speed and improve the screening quality; a motor is installed in the console and used for controlling the vibrating frequency and amplitude of the spring vibrators. Particle raw materials enter the screening box to be sorted in a classification manner sequentially through twice screening processes of the upper sieve plate and the lower sieve plate. The particle material classification sorting device can be used for realizing the continuous and stable classification sorting operation, is simple in structure and high in efficiency, and can be widely used for sorting particles in a classification manner in the fields of food, medicines, chemical industry, light industry and the like.

Description

technical field [0001] The invention relates to a grading and screening device for granular materials, in particular to a device for completing material grading and screening by setting two sieve plates with different sieve hole diameters according to the particle size of the material, and belongs to the field of particle classification. Background technique [0002] The screening device is a device that distinguishes materials according to the size of the particle diameter. It mainly compares the diameter of the sieve hole on the sieve plate with the size of the particle diameter of the material, so as to achieve the purpose of distinguishing and selecting the required particles. At present, in chemical operations, certain crystal particles are often needed, but some crystal particles are of different sizes, so it is necessary to select and separate particles of different sizes; and in other industries, it is necessary to strictly ensure the size uniformity of particle produ...

Problems solved by technology

Manual screening mainly relies on the manual use of sieves to select granular materials. This method is labor-intensive and the production efficiency is not high; mechanical screening often uses material screening machines with complex structures. Although the efficiency is high, the mechanical structure is complicated. Large space, not suitable for screening tasks with different processing volumes

And the above method can only complete the screening of materials with one particle diameter at a time, and the operation is relatively simple
