Crushing device for recycled concrete production

Abstract

The invention discloses a crushing device for recycled concrete production. The device comprises a feeding box and a processing box, the bottom of the feeding box communicates with the left side at the top of the processing box, and a first crushing roller set is rotationally connected between the front side and the rear side of an inner cavity of the processing box through bearings. A conveying plate is rotationally connected to the top of the left side of the inner cavity of the processing box through a rotating block, and a transverse plate is fixedly connected to the position, located below the conveying plate, at the left side of the inner cavity of the processing box. The crushing device for recycled concrete production relates to the recycled concrete production technical field, after the preliminary crushing, the waste concrete is directly subjected to spray washing treatment, and the impurities are screened out, so that the treatment capacity of the device on the waste concrete can be reduced, the gaps on the surface of the waste concrete can be looser, the crushing is facilitated, and then the crushing treatment is conducted, and accordingly the crushing effect of the device on the waste concrete can be guaranteed, and the later-period reuse machining quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of recycled concrete production, in particular to a crushing device for recycled concrete production. Background technique [0002] Recycled concrete means that waste concrete blocks are crushed, cleaned and graded, mixed with gradation in a certain proportion, partially or completely replaced by natural aggregates (mainly coarse aggregates) such as sand and gravel, and then added with cement, water, etc. According to the combination of aggregates, recycled concrete can have the following situations: all aggregates are recycled aggregates; coarse aggregates are recycled aggregates, fine aggregates are natural sand; coarse aggregates are natural crushed Stones or pebbles and fine aggregates are recycled aggregates; recycled aggregates replace part of coarse aggregates or fine aggregates. [0003] In the process of processing waste gas concrete blocks, it is necessary to undergo multiple crushing and cleaning...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a crushing device for recycled concrete production, which solves the problem of cleaning waste concrete after the crushing is completed, which increases the processing capacity of the waste concrete by the device. At the same time, due to the large surface gap of the crushed aggregate, it is easy to absorb water and saturate, and the looseness is high. The existing crushing technology cannot crush the waste concrete strongly, which affects the quality of reuse.
