Building waste crushing and screening comprehensive treatment device for building construction

Abstract

The invention discloses a building waste crushing and screening comprehensive treatment device for building construction, and relates to the technical field of building waste treatment. The building waste crushing and screening comprehensive treatment device comprises a crushing box body, a feeding hopper is arranged at the top of the crushing box body, crushing rollers are arranged in the crushing box body, crushing teeth are arranged on the crushing rollers, a partition plate is arranged in the crushing box body, a dust removal pipe is arranged on the lower surface of the partition plate, a rotating shaft is rotationally arranged in the dust removal pipe and provided with a spiral blade, a conveying pipeline is arranged on one side of the dust removal pipe and penetrates through the crushing box body to extend into a screening box body of a screening mechanism, supporting columns are arranged in the screening box body at intervals, conveying rollers are arranged in the supporting columns, and a conveying belt is arranged on the outer surfaces of the conveying rollers in a conveying mode. According to the building waste crushing and screening comprehensive treatment device for building construction, the requirement for crushing treatment of a large batch of construction waste can be met, dust pollution to the surrounding working environment and workers is avoided, meanwhile, iron impurities in the construction waste can be screened, and thus the phenomenon that the construction waste covers the iron impurities so that the iron impurities cannot be adsorbed out can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a construction waste crushing and screening comprehensive treatment device for construction. 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] With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly at the same time, and the...

Problems solved by technology

If it is not processed and utilized in time, it will definitely have adverse effects on society, the environment and resources

[0004] At present, there are the following technical problems in the existing construction waste disposal: 1. Construction waste is often mixed with a large number of concrete blocks and scrap metal, which occupies a large area. 2. Some existing crushing devices, when crushing construction waste, will cause dust to fly around, causing serious damage to the surrounding environment and staff. The dust generated during the crushing process has not been collected centrally, and the health of the staff who have been in the dusty working environment for a long time has been greatly threatened, and it is difficult to meet the actual needs of the large-scale construction waste crushing and treatment of enterprises. 3. The broken construction waste often contains a large amount of iron impurities, which need to be recycled and reused, because the construction impurities will cover or block the iron impurities. Some existing conventional electromagnet adsorption devices There is a situation that it is difficult to completely absorb iron impurities, which will bring huge losses to enterprises and society in terms of large-scale iron recycling of construction waste. Therefore, how to completely screen out iron impurities in construction waste , is an important technical problem that our company needs to solve
