Construction waste treatment device

Abstract

The invention discloses a construction waste treatment device, and belongs to the field of construction waste. The construction waste treatment device comprises a preliminary crushing chamber, a feeding bin is arranged on the right side of the preliminary crushing chamber, a drainage pipe is arranged at the position, close to the bottom side, of the rear side of the preliminary crushing chamber, a filter plate is fixedly connected to the front end of the drainage pipe, an inverted U-shaped base is fixedly connected to the top of the preliminary crushing chamber, sliding grooves are formed in the inner walls of the two opposite sides of the inverted-U-shaped base, the bottom sides of the sliding grooves extend to the positions close to the inner wall of the bottom side of the preliminary crushing chamber, a preliminary crushing plate is connected between the two sliding grooves in a sliding mode, and preliminary crushing teeth which are evenly distributed are arranged on the bottom side of the preliminary crushing plate. The construction waste treatment device has the advantages that concrete blocks containing iron nails and reinforcing steel bars generated by removal can be separated, in addition, the iron nails and the reinforcing steel bars are separated from the concrete blocks, and therefore the situation that a crushing device is jammed by the iron nails and the reinforcing steel bars or the crushing device is quickly worn when the concrete blocks are crushed can be effectively reduced.

Description

technical field [0001] The invention relates to the field of construction waste, more specifically, to a construction waste treatment device. 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 block, waste plastic, waste metal, waste bamboo and wood, etc. [0003] The construction waste generated from demolition often contains a large number of iron nails and steel bars. These iron nails and steel bars are generally fixed together with concrete and it is difficult to s...

AI Technical Summary

Problems solved by technology

[0003]Construction waste generated from demolition often contains a large number of iron nails and steel bars, which are generally fixed with concrete and difficult to separate separately. When recycling and crushing this part of construction waste, the iron nails, steel bars, and concrete blocks are all crushed together, but the iron nails and steel bars have high hardness and are difficult to crush, which is easy to jam the crushing device or cause rapid wear of the crushing device
