Description

A kind of screen classifying equipoment that high production capacity is easy to maintain

Technical field

The invention belongs to the technical fields of mechanical equipment, are more specifically related to a kind of screen that high production capacity is easy to maintain classification and set It is standby, it is widely used in powder or particulate material in the industries such as flour processing, food, pharmacy, feed, chemical industry, mine, alcohol, starch Screen, classification and removal of impurities.

Background technique

In powder processed and feedstuff industry, usually by screen classifying equipoment to powder or particulate material carry out screen, classification and Removal of impurities, to meet the material requirement of multi items.The yield of screen classifying equipoment, efficiency, grading effect are whole process lines Emphasis performance indicator, if yield is inadequate or grading effect is bad, will seriously affect following process manufacture craft it is smooth into Row, and then influence the usage experience of client.

Currently, screen classifying equipoment in the market mostly has the following disadvantages:

(1) sieve lattice difficulty changes, is not easy to safeguard and clear up: conventional screen lattice usually use whole storehouse stacked structure, are compressed by level It is fixed on sieve nest or in sieve nest with the form that vertical compression combines, if there is paste sieve, putty, blowby material or damage etc. Failure, it is necessary to sieve lattice all be dismantled, clear up or carry out in layers exclusion inspection, the maintenance cost of equipment in layers Height, production efficiency are low, also seriously constrain the normal operation of whole production line.

(2) built-in transmission device occupies sieve nest inner space big, fluctuation of service, difficult in maintenance: traditional screen classification Equipment is essentially all using a set of built-in transmission device, and transmission device is usually placed in the inside of sieve nest.On the one hand, it is driven Device occupies a large amount of sieve nest inner space, influences the design of the arrangement on the road Shai Geheshai and sieve nest discharge port in sieve nest, Also affect the raising of production efficiency of equipment and production capacity；On the other hand, due to there was only a set of transmission device, thus equipment is operating Shi Yingli is concentrated in sieve nest side, causes equipment stress raisers, is easy to be destroyed, there are larger security risks；Meanwhile When transmission device needs repairing and maintains, it is necessary to equipment is opened, related components is removed and just can be carried out, cumbersome, work Amount is big, maintenance period is long, and frequently disassembles and installs also the precision and service life that will affect transmission parts.

(3) material is uneven along single channel one direction or multichannel one way flow, sub-material: in traditional screen equipment, object Material enters sieve nest generally along single channel one direction or multichannel one way flow from feed inlet, is assigned on every road compass screen surface in this way Material is more and uneven, and screening effect is poor, screening efficiency is low.

Summary of the invention

A kind of high production capacity that the purpose of the present invention exactly provides in view of the deficiencies of the prior art screen easy to maintain Classifying equipoment.External transmission in the present invention can be realized sieve nest inner space big, sieve road layout optimization, easy to repair With maintain, run smoothly, use the technical effects such as safe, production efficiency is high；Meanwhile using the layered arrangement of sieve lattice in the present invention It arranges with zigzag, is equipped with reasonable foodstuff refiner, material may be implemented and sieved evenly along multichannel mutual entry difference The material sendout of the compass screen surface of lattice, reduction and balanced every layer of sieve lattice, improves screening efficiency and production capacity；Pull knot in the present invention The screen frame of structure, the sieve door for sieving lattice and rotating folding, not only facilitate the cleaning of sieve lattice and screen frame, but also are able to achieve sealing and compression, operate Simply, using flexible.
