PL123781B2 - Screen for sieving of loose, granular and lump materials - Google Patents

Description

The subject of the invention is a sieve for screening loose, granular and lumpy materials. The so far used rotating sieves in oscillating motion required periodic cleaning with mechanically compressed air, water or manually. The aim of the invention was to develop such a construction of the sieve that does not require cleaning during operation. with walls and guides. A sliding weight is placed in the guide or on it, which during the sieve operation falls by gravity causing vibrations that disappear from the walls. An advantage of the solution according to the invention is that the induced vibrations of the opposing screens of the screen cause an intensification of sowing on the side provided with the screened material, and on the opposite side, it is cleaned by slapping. in the operating plane of the device, and Fig. 2 shows a cross-section of the oscillating wire in the operating plane of the device. A guide 2 is mounted in the housing of the screen 4, in which the weight 1 slides loosely. The weight moves in the guide by gravity when the screen rotates or oscillates, hitting the resistance 3, causing the vibration phenomenon of both sides of the screen, connected with the guide. granular and piece pieces with a circular or other cross-section, characterized by the fact that a guide (2) is mounted between the opposite walls of the screen (4), in which a sliding weight (1) is placed. 123 781 Pracownia Poligraficzna UP PRL.
