Technical field
The present invention relates to the separation equipment of solid material in chemical process, more particularly to one kind to be applied to a variety of particle diameters
The multistage sieve with blower material equipment of raw material separation.
Background technology
The solid product of Chemical Manufacture includes a variety of particle diameters, and typically two kinds of operative employees are used for the product of different-grain diameter
Skill, a kind of is to be crushed the particle of wherein big particle diameter, and the material of all particle diameters is all ground into short grained material,
Carry out unified collection and discharging；Another kind is that the product of different-grain diameter is carried out into screening with screen cloth to come, by the production of different-grain diameter
Product are collected respectively, with suitable for different supply of material demands.
Worked for the category filter of different-grain diameter material, generally require and it is screened using multilevel screen, still
Normal practice on the market is to need repeatedly to screen material, and the screen cloth from different-grain diameter carries out sieve material operation respectively,
And then the product of different-grain diameter is collected, and it is cumbersome, waste time and energy；There are some to also have the sieve material of multilayer screen cloth simultaneously on the market
Equipment, although these equipment can disposably sieve material and complete, the operation of its feeding needs to dismantle and remove mesh structure respectively, grasps
It is also inconvenient to make to get up, while during sieve is expected, the material of bulky grain easily blocks mesh structure, causes short grained material
It can not pass through, sieve material efficiency is low, it is necessary to coordinate the structure of other mechanical oscillation could complete sieve material operation.
The content of the invention
For above-mentioned problem, convenient with rewinding present invention aims at a kind of sieve material is provided, sieve material efficiency is high, full
The a variety of particle diameter materials of foot are screened and collected simultaneously the multistage sieve with blower material equipment of operation.
