Construction waste cyclic crushing device

Abstract

The invention discloses a construction waste cyclic crushing device, and relates to the field of construction waste treatment. The construction waste cyclic crushing device comprises a treatment main box, a falling hopper is horizontally welded to the top surface of the treatment main box, outer cover bodies are symmetrically welded to the two side edges of the falling hopper, and a supporting vertical rod is vertically and downwards welded to the bottom surface of the treatment main box; and a discharging bottom hopper is horizontally welded to the bottom face of the treatment main box, a control panel is embedded at one side edge of the treatment main box, treatment side boxes are symmetrically connected to the two side edges of the treatment main box through bolts, outer conveying rollers are horizontally inserted into the inner side edges of the treatment side boxes, and ventilation grooves are horizontally and evenly formed at one side edge of each treatment side box. A guide hopper is welded on the bottom surface of each treatment side box. According to the device, the design is integrated, the structure is simple, operation is easy and convenient, the crushing and screening integrated design is adopted, so that construction waste treatment is faster and more efficient, meanwhile, the abrasion condition can be controlled through classification treatment, and the device can circularly work for a long time.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a construction waste recycling crushing 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. With the increase in the amount of urban construction waste, the number of garbage dumps is also increasing, and the area of ​​the garbage dump is also gradually expanding. The phenomenon of garbage and people competing for land has reached a very serious level. Most of the suburban garbage dumps are mainly piled in the open air. After long-term exposure to the sun and rain, harmful substances in the garbage (including urban construction waste) Polycyclic aromatic hydrocarbons released from paints, coatings and aspha...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of construction waste circulation crushing device, to solve the above-mentioned background technology when processing the current construction waste, it is centralized stacking or landfill treatment, so that the construction waste cannot be rationally processed. The separation of the construction waste makes it impossible to effectively use the construction waste, resulting in the random dumping of the construction waste and forming a waste situation, and the current crushing equipment is only for crushing, so that after a long period of crushing, the internal parts will be relatively large. A large degree of wear and tear requires replacement of internal parts, which causes a certain amount of trouble and waste of money, and the pulverization is not thorough enough to require repeated pulverization, which affects work efficiency.
