Building waste crushing and recycling device

Abstract

The invention discloses a device for crushing and recycling construction waste, which comprises a box body, a crushing chamber is arranged on the upper part of the inner cavity of the box body, a grinding chamber is arranged on the lower part of the inner cavity of the box body, and lifting chambers are arranged on both sides of the lower inner cavity of the box body The crushing chamber and the grinding chamber are separated by a partition. The movable jaw plate, the first connecting rod, the second connecting rod and the No. 1 motor are arranged symmetrically on the top plate of the box body. The fixed seat, the top fixed frame of the fixed seat is provided with a No. 1 material guide slant plate, and the No. 2 motor is symmetrically fixed on the two side walls of the fixed seat. The output shaft of the No. 2 motor is driven and connected with a rotating shaft. The outer ring of the rotating shaft is uniform Several crushing blades are fixedly installed, and the inner turret of the grinding chamber is equipped with No. 1 grinding roller and No. 2 grinding roller. The invention has simple structure, convenient use, can fully crush and grind construction waste, has good effect and high efficiency, and is beneficial to the recycling of construction waste.

Description

technical field [0001] The invention relates to the field of construction waste recycling, in particular to a construction waste crushing and recycling device. Background technique [0002] With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly, and the accompanying construction waste is increasing. The amount of construction waste in China has accounted for more than 1 / 3 of the total urban waste. Construction waste refers to the collective name of muck, waste concrete, waste masonry and other waste produced in the production activities of people engaged in demolition, construction, decoration, repair and other construction industries. According to the source of production, construction waste can be divided into engineering dregs, decoration waste, demolition waste, engineering mud, etc. The vast majority of construction waste is transported to the outskirts or villages by the construction unit without any treatment...

AI Technical Summary

Problems solved by technology

The vast majority of construction waste is transported to the outskirts or villages by the construction unit without any treatment, and is piled up in the open air or landfilled, which consumes a lot of construction funds such as land acquisition fees, waste clearance and transportation fees, and pollutes the environment

[0003] The crushing effect of the construction waste crusher in the prior art is poor, and its crushing efficiency is low, which is not conducive to the recycling of construction waste
