Concrete crushing and recycling device

Abstract

The invention discloses a concrete crushing and recycling device. The concrete crushing and recycling device comprises a crushing mechanism, a dust channel and a mud generating mechanism, wherein thedust channel is formed in one side of the crushing mechanism; and the mud generating mechanism is arranged on one side of the dust channel. According to the concrete crushing and recycling device, a crushing roller adjusting mechanism is additionally arranged, and the distance between crushing rollers can be adjusted in real time according to concrete of different sizes, so that the crushing effect is better, jamming is prevented, and the crushing efficiency is improved; and dust generated in the crushing process is collected and made to form mud under the action of an atomization spraying mechanism, and the mud is discharged under the combined action of a mud settling mechanism and a discharge box, so that the dust is effectively controlled, and the environmental pollution is prevented; and meanwhile, the dust can be reprocessed and reutilized, so that raw materials are saved, and waste is prevented.

Description

technical field [0001] The invention belongs to the technical field of environmental protection energy regeneration, and in particular relates to a device based on recovery and reuse of broken concrete. Background technique [0002] After the concrete structure used in the building is discarded, it can be recycled and reused after treatment. After crushing, it can produce coarse and fine aggregates and a large amount of dust, which can be directly used as raw materials for cement. At the same time, the aggregates produced It can also be used to replace stones in the production of insulation bricks, blind holes, etc., so that energy can be recycled; [0003] After searching the patent application publication number CN111632667A, an environmentally friendly crushing device for recycling and reuse of concrete blocks in buildings, including a fixed frame, the grinding cylinder is provided with a translation mechanism for driving the grinding mechanism to move laterally, and the ...

AI Technical Summary

Problems solved by technology

[0004] It has the following disadvantages: 1) when crushing by crushing rollers, since the distance of the crushing rollers is a fixed distance, it cannot be adjusted in real time according to the size of the concrete block, and it is easy to cause jamming when crushing some larger concrete blocks. And the crushing is not thorough enough, which leads to relatively low efficiency in the crushing process; 2) When dealing with a large amount of dust generated in the crushing process, only the dust is absorbed by the vacuum cleaner, which cannot completely and effectively achieve the effect of environmentally friendly crushing At the same time, the crushed dust can be used as raw materials for cement production, and the direct absorption operation will lead to waste of raw materials
