The roller screen mainly completes the conveying of materials on the screen through the friction force between the screen discs and the materials, and the materials smaller than the gaps between the screen discs complete the passing through of the screen and enter the screen below. When the materials fall to the lower roller through the upper roller, a certain fall exists, the materials can complete layer turning, and screening of light materials is facilitated.
The sieve tray form of upper screen axle is the triangle dish, peculiar triangle dish structure not only makes screening aperture size keep invariable, the screening in-process can produce very effectual "wave type and mix the effect", can obtain very good dispersion when the material keeps forward rapid motion, the load factor of sifter has not only been reduced, the adhesion of tiny material on the sifter has also been reduced effectively, eliminate the probability that the sieve mesh is blockked up and rectangular material gets into the sieve mesh by the bold material, realize the best screening effect, in addition, special triangle dish structure, can effectively reduce the winding of rectangular material, simultaneously still have certain crushing effect to glass.
The synchronous rotation of triangle dish and the size rectangle sieve mesh that remains unchanged throughout make upper screen shaft have the efficient from the cleaning function, can effectively prevent the winding and the jam of material. When the plate point of a triangular plate rotates downwards, the plate point of another interactive triangular plate can clean and remove the materials adhered to the surface of the plate, and the probability of winding of the long-strip flexible materials on the sieve surface is reduced.
The screen disc of the lower screen shaft is in a disc shape or is provided with small teeth on the periphery, and the central line of the adjacent teeth of the gear disc forms an angle with the central point of the screen disc, wherein the angle is 20-40 degrees; preferably 30 deg., especially 30 deg., it can separate large-sized materials from film, plastic and other metal material flows, maintain the optimum state of separation and the highest purity of separated materials. In practical engineering application, separation of the yellow board paper is generally referred to, and a unique sieve tray type and tray distance design can be designed according to requirements, so that the purity of required materials (such as the yellow board paper) can be ensured, and the processing load and difficulty of a subsequent flow distribution system can be obviously reduced.
The roller screen adopts a two-section design, so that the material can generate a turning and throwing effect, and the two sections of screen surfaces are designed in a negative angle, so that the screening efficiency is high; due to the special structural design, timely material conveying is guaranteed, and the handling capacity is high; the special sieve tray structure can fully prevent materials from winding and provide the working stability of the equipment; the special sieve tray structure can make the material in the wavy transmission of sifter side, improves screening efficiency.
In the invention, each roller is driven by one driving device independently, and one or more driving devices can drive the rollers to rotate through chain transmission, belt transmission or the like to complete screening work.
It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
