Composite multi-stage bag breaking screening machine in friction drive mode

Abstract

The invention relates to a composite multi-stage bag breaking screening machine in a friction drive mode. The composite multi-stage bag breaking screening machine is used for disposing municipal solid waste, and structurally comprises a screen drum arranged inside a sealing cover; the sealing cover is fixed onto a height-adjustable support assembly by a tray assembly, the screen drum is obliquely arranged in such a manner that a feed end of the screen drum is higher than a discharge end of the screen drum, driving devices are fixedly arranged on the support assembly and comprise driving motors and supporting wheels connected with the driving motors, the supporting wheels are in close contact with the screen drum, and the screen drum is driven by friction force generated among the supporting wheels and the screen drum to rotate; and the screen drum comprises screen plates, the screen plates are provided with screen openings with different apertures, are axially and sequentially connected with one another and encircle a steel framework to form a drum body, and a plurality of bag breaking knives and a plurality of tearing knives are mounted on inner sides of the screen plates. The friction drive mode and a finite element analysis technology are creatively adopted, functions of bag breaking and multi-stage screening are integrated, the composite multi-stage bag breaking screening machine is provided with a unique non-drive automatic cleaner, stepless speed changing is realized, and problems of blockage of screen openings, twining of knives, distortion and damage of transmission bearings and the like during running of equipment are solved.

Description

technical field [0001] The invention relates to a sorting device for bag breaking and screening of urban living garbage, in particular to a friction-driven compound multi-stage bag breaking and screening machine capable of breaking bags for processing urban living garbage. Background technique [0002] With the acceleration of urbanization, the phenomenon of garbage siege is becoming more and more serious. At the same time, resources and energy are gradually scarce. Waste recycling technology can solve the above two problems to a certain extent. Waste resource treatment first needs to carry out pretreatment such as bag breaking and screening of garbage. At present, most of the domestic bag breaking and screening processes are completed in two sets of equipment, and most of them use direct bearing or chain transmission to prolong the process. Also increased equipment maintenance cost simultaneously. Contents of the invention [0003] The purpose of the present invention is...
