Multi-stage treatment device for building waste and using method

Abstract

The invention provides a multi-stage treatment device for building waste and a using method. The multi-stage treatment device for the building waste comprises a tank body, two crushing rollers, two first motors, an annular groove and a guide ring, wherein the two crushing rollers are rotationally installed in the tank body and are meshed with each other; the two first motors are fixedly installed on the same side of the tank body, and output shafts of the two first motors are fixedly connected with output shafts of the two crushing rollers correspondingly; the annular groove is formed in the inner wall of the tank body; and the guide ring is rotationally installed in the annular groove, and the inner ring of the guide ring is located in the tank body and is located below the two crushing rollers. The multi-stage treatment device for the building waste and the using method have the advantages that bamboo and wood can be crushed, meanwhile, iron nails in the bamboo and wood can be screened, moreover, the bamboo and wood can be dried, and the recovery difficulty can be reduced.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a multi-stage treatment device for construction waste and a method for using it. Background technique [0002] Construction waste refers to the general designation 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 classification of generation sources, construction waste can be divided into engineering slag Soil, decoration waste, demolition waste, engineering mud, etc.; classified by composition, construction waste can be divided into muck, concrete blocks, crushed stones, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste Metal, waste bamboo and wood, etc., with the rapid development of the construction industry, more and more construction wastes are produced during the cons...

[0002] Construction waste refers to the general designation 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 classification of generation sources, construction waste can be divided into engineering slag Soil, decoration waste, demolition waste, engineering mud, etc.; classified by composition, construction waste can be divided into muck, concrete blocks, crushed stones, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste Metal, waste bamboo and wood, etc., with the rapid development of the construction industry, more and more construction wastes are produced during the construction process. If these construction wastes are discarded directly, it will not only cause a waste of resources, but also affect the social environment. Therefore, people gradually began to study how to recycle construction waste, and on this basis, more and more waste treatment devices were developed.

[0003] However, because most of the waste in construction waste is concrete, masonry and steel bars, etc., most of the waste treatment devices that have been developed are aimed at such materials, and they are relatively weak in recycling waste bamboo and wood. During construction, people often use iron nails to fix bamboo and wood, which makes it easy to hurt people when they are screened after treatment, and bamboo and wood absorb water more seriously after becoming waste, and it is more difficult for people to recycle.
