Sorting device for treating construction waste, and recycling system and method for construction waste

Abstract

The invention discloses a sorting device for treating construction waste, and a recycling system and method for the construction waste. The sorting device includes a machine frame, a belt disposed onthe machine frame and carrying and transporting the construction waste, a driving mechanism for driving the belt to rotate, and a magnetic assembly disposed on the machine frame, located between an upstream belt section and a downstream belt section, arranged near one end of the belt that outputs the construction waste, and adsorbing ferromagnetic substances in the construction waste to the uppersurface of the upstream belt section and the lower surface of the downstream belt section, wherein the belt includes the upstream belt section and the downstream belt section, and during a process that the downstream belt section drives the ferromagnetic substances to move away from the end of the belt that outputs the construction waste, the ferromagnetic substances gradually fall under the action of gravity. A purpose of replacing a manual sorting manner and efficiently removing the ferromagnetic substances from the construction waste is achieved.

Description

technical field [0001] The invention relates to the field of resource regeneration treatment of construction waste, in particular to a sorting device for processing construction waste, a system and a method for recycling construction waste. 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. [0003] There are mainly three types of traditional treatment methods for construction waste in my country. One is direct landfill, which is used for land reclamation in coastal cities, but excessive land reclamation seriously damages the marine ecological environment and is strictly restricted; the other is direct paving, which leads to road construction. The quality has declined, there is a huge potential safety hazard, and it is prohibited to use; the third is la...

Problems solved by technology

[0005] However, people usually use crushers to crush construction waste. Although the crusher has high efficiency, it is still difficult to completely separate the concrete and steel bars, resulting in the technical problem of "rebar hanging blocks". Manual sorting is required, which is cumbersome, costly, inefficient and unsafe, which is not conducive to achieving large-scale and efficient processing of construction waste
