Garbage harmless treatment equipment for urban construction

Abstract

The invention belongs to the technical field of garbage treatment, and particularly relates to harmless garbage treatment equipment for urban construction, which comprises a rack, and a crushing assembly for crushing bricks and stones and a slow discharging assembly for slowly discharging crushed bricks and stones are mounted at the top of the rack; the same iron removal assembly capable of adsorbing steel and iron scraps is connected between the crushing assembly and the slow discharging assembly, a feeding hopper used for feeding is installed at the top of the crushing assembly, and two symmetrically-distributed buffering protection assemblies for slowing down the falling speed of bricks and stones and preventing crushed bricks and stones from splashing are rotationally installed in the feeding hopper; air curtains for preventing dust from escaping are symmetrically installed on the inner walls of the two sides of the feeding hopper, and air blown out by the air curtains forms an eddy current capable of gathering dust below the buffering protection assembly. The dust-proof and protection device has good dust-proof and protection effects, and metal resources in garbage can be recycled.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a harmless treatment equipment for urban construction garbage. Background technique [0002] With the development of social economy, my country continues to deepen urban construction, because my country's modern urban construction is mainly based on concrete buildings, concrete buildings have a certain service life limit due to aging problems, and the service life of concrete buildings in my country is mostly designed to be 70 Around 2000, these old buildings continued to be demolished and rebuilt. A large amount of construction waste will be generated after the demolition of concrete buildings. The amount of construction waste is the largest. Most of the construction waste is transported to the outskirts or villages by the construction unit without any treatment, and is piled in the open air or landfilled, which consumes a lot of construction funds such as land acquisiti...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing crushing devices usually use water spray to suppress the generation of dust when crushing waste masonry, but the dust will produce a large amount of mud after the rain, and the leakage of these mud will also cause environmental pollution. At the same time, it also consumes a lot of water resources; and in the process of breaking masonry, it is easy to cause masonry particles to splash and hurt people;

[0005] 2. At the same time, some of the crushed masonry will carry steel bars and iron wires. If these metal resources can be recycled, it will save some costs; at the same time, the direct discharge of crushed masonry particles will also generate a lot of dust, and The masonry particles with sharp edges can easily scratch the packaging bag or even cause accidents of brushing and hurting people
