Description
Technical field
The utility model relates to a kind of sieving machine, especially a kind of sieve nest structure of sieving machine.
Background technology
Screening plant is widely used in the industries such as agricultural byproducts, food, medicine, feed, chemical industry, the energy and uses.Traditional screening plant involving vibrations screening machine, cylinder round sifter, airflow shifting machine; its shortcoming is in screening process; material easily stops up sieve aperture; be difficult for sieve thoroughly; therefore screening efficiency is lower; especially the less solid particle of screen cloth oscillatory type sieve diameter; be subject to sometimes the moisture of particle and the restriction of viscosity in material; moisture is crossed conference makes material produce granulationization tendency; make the particle that originally can be used as screenings because uniting as oversize; and discharged by the upper outlet of sieve, cause waste.More seriously, the conference of solid particle material viscosity makes solarization face knot layer, and then causes screening machine can not normally complete screening task.
At present, in to the preparation of different powders and application, a lot of multi-form sieve powder devices have been there are.In existing sieving machine conducting powder grain screening process, common employing wind send or helical feed mode is carried powder, and employing wind is sent the sieving machine of row conveying to because wind regime affects, and can cause some impurity to enter into material with wind regime, cause product impure, thereby reduced the quality of screening product.
Utility model content
The purpose of this utility model is to provide a kind of by the sieve nest structure of the centrifugal sieving machine combining with vibratory sieve principle, is applicable to screening more sticky material and superfine material, thoroughly sieves effectively, and screening efficiency is high.
The utility model is achieved by the following technical solution:
The sieve nest structure of sieving machine, comprise sieve nest, screen drum and motor, described sieve nest is provided with feed hopper and discharge bucket, discharge bucket is comprised of thick discharge bucket and thin discharge bucket, in sieve nest, be provided with screen drum, the top of screen drum one end is provided with feed hopper, screen drum other end bottom is provided with thick discharge bucket, below screen drum, be provided with thin discharge bucket, above described sieve nest, be provided with gas outlet, in sieve nest, be provided with the screen drum of horizontal setting, the both sides of screen drum central shaft are respectively equipped with bearing bracket, bearing bracket is located at the outside of described sieve nest, bearing bracket is respectively equipped with outside framework oil seal near a side of screen drum, the inner side of outside framework oil seal is respectively equipped with baffle plate.
As optimal technical scheme of the present utility model, above described sieve nest, be provided with at least two gas outlets, gas outlet is provided with wire screen.
As optimal technical scheme of the present utility model, the order number of described wire screen is 80 order to 120 orders.
As optimal technical scheme of the present utility model, the two ends of described sieve nest are respectively equipped with sieve plate, and sieve plate is connected with sieve nest by embedded mode, between sieve plate and sieve nest, are provided with sealing gasket.
As optimal technical scheme of the present utility model, described sieve plate is provided with open slot, and sieve plate is made as easy-to-dismount movable connection method by the screw rod with star-like handle and sieve nest.
The beneficial effects of the utility model are: with respect to prior art, the utility model is rational in infrastructure, good seal performance, and material is difficult for contaminated.Screen drum and while re-packing High Rotation Speed, on sieve nest, two gas outlets that are covered with wire screen can the inside and outside pressure of balance sieve nest, is conducive to material and moves in order, avoids disorderly interference in air flow material movement in sieve nest, thereby raising screening efficiency, and can effectively reduce excessive Dust Capacity.The utility model not only can be saved raw material, and screening efficiency is high, and the quality of material after screening is better, pollutes still less, is specially adapted to amino film plastics and other sieves exigent material.
