Multistage screening system capable of treating construction and decoration waste

Abstract

The invention provides a multistage screening system capable of treating construction and decoration waste. The multistage screening system capable of treating the construction and decoration waste comprises a motor, a screening box, an auger delivery device, screen clearing belts, screens and screen barrels. The multistage screening system is characterized in that the auger delivery device is horizontally placed in the screening box; the position of a center shaft of the screening box is connected with a driving shaft; the driving shaft is sleeved with a belt pulley; the belt pulley is connected with the motor; the screens comprise the narrow-meshed screen, the medium-meshed screen and the wide-meshed screen and are arranged in the screen barrels in the advancing direction of materials sequentially; a fine material outlet, a medium-sized outlet and a rough material outlet are formed in the bottoms, corresponding to the narrow-meshed screen, the medium-meshed screen and the wide-meshedscreen, of the screen barrels sequentially; the shaft end of a rotating shaft is sleeved with a screen clearing belt pulley; the screen clearing belt pulley is connected with a belt pulley belt; andthe screen clearing belt is located above the screens and advances from left to right. The auger delivery device of the multistage screening system grinds and delivers the materials through unceasingrotation, so that stage treatment on the materials is realized; and the multistage screening system is simple to assemble, so that the assembling intensity of technical personnel is not increased.

Description

technical field [0001] The invention relates to a multi-stage screening device for garbage, which belongs to the field of mechanical equipment, in particular to a multi-stage screening system for processing construction and decoration waste. Background technique [0002] In the construction industry, waste disposal after completion has always been a problem, and materials need to be screened according to their size. At present, there are vibrating screens that use vibrating motors to vibrate as a vibration source, so that materials are thrown up on the screen and move forward in a straight line at the same time. The upper material and the lower material are discharged from their respective outlets; the single vibrating screen used can only screen the raw material into two specifications. If it is to be screened into multiple specifications, multiple vibrating screens need to be arranged according to the size of the screen. The vibrating screen takes up a lot of space and is...

Problems solved by technology

At present, there are vibrating screens that use vibrating motors to vibrate as a vibration source, so that materials are thrown up on the screen and move forward in a straight line at the same time. The upper material and the lower material are discharged from their respective outlets; the single vibrating screen used can only screen the raw material into two specifications. If it is to be screened into multiple specifications, multiple vibrating screens need to be arranged according to the size of the screen. In the form of vibrating screen, it takes up a lot of space and is noisy. It needs to be screened many times, and the efficiency is low.
