Building waste crushing device for building engineering management

Abstract

The invention discloses a building waste crushing device for building engineering management. A roller crusher is included. The left side of the roller crusher is obliquely provided with a first conveyor, and the bottom discharging port position is horizontally provided with a second conveyor. A metal separator is arranged at the middle portion of the second conveyor, and the tail end is providedwith a sorting conveyor. A material guiding funnel is arranged on the right side of the metal separator. The sorting conveyor is of a three-layer structure and sequentially comprises a metal conveyor,a stone conveyor and a sand stone conveyor from top to bottom. A plurality of supporting rods are evenly arranged among the metal conveyor, the stone conveyor and the sand stone conveyor. The left end of the metal conveyor is symmetrically provided with two connecting rods located under the material guiding funnel. According to the building waste crushing device, after waste crushing is finished,a special conveying sorting mechanism is designed, the purpose of automatic classification can be achieved in the conveying process, regenerated material classified recycling is facilitated, and thewaste treatment effect and the automation degree are greatly improved.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a construction waste crushing device for construction project management. Background technique [0002] Construction waste refers to the general designation of muck, waste concrete, waste masonry and other waste generated in the production activities of people engaged in demolition, construction, decoration, repair and other construction industries. Classified by source, construction waste can be divided into engineering dregs, decoration waste, demolition waste, engineering mud, etc.; classified by composition, construction waste can be divided into muck, concrete blocks, crushed stones, brick fragments, Waste mortar, mud, asphalt blocks, waste plastics, waste metal, waste bamboo and wood, etc. The common construction waste in construction is waste concrete stones, which need to be crushed by special crushing equipment for waste reuse to achieve sustainable ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing concrete stones have the following problems in the process of crushing: (1) The existing method for crushing concrete stones in construction waste is relatively simple, and there is no special classification mechanism after the crushing is completed , causing stones, gravel and metals to be classified unreasonably, secondary treatment is required, and the degree of automation is low; (2) The treatment method of the construction waste damage device for concrete stones is unreasonable, which affects the treatment effect
