Dry-type sorting system for construction waste

Abstract

The invention discloses a dry-type sorting system for construction waste. The dry-type sorting system includes a vibrating feeding sorting machine, a first sorting mechanism, a crushing machine, an iron removing device and a second sorting mechanism. The vibrating feeding sorting machine is provided with a small waste separation mechanism. The first sorting mechanism includes a first sorting platform, a soft and light waste grabbing mechanism and a first sorting centralization mechanism, and the soft and light waste grabbing device is transversely placed above the first sorting mechanism. Thecrushing machine is arranged behind the first sorting mechanism, waste falling from the first sorting mechanism is carried through a first transportation belt, and a second transportation belt is arranged below a crushing outlet. The iron removing device is arranged above the second transportation belt. The second sorting mechanism is arranged at the tail end of the second transportation belt, thesecond sorting mechanism comprises a second sorting platform, a second sorting centralization mechanism and a light waste secondary sorting mechanism, a discharging belt is connected to the tail endof the second sorting mechanism, and the second sorting centralization mechanism is separately connected with the light waste secondary sorting mechanism and the discharging belt in a butting mode. The dry-type sorting system for the construction waste has the advantages that separation of different waste is realized on each mechanism of the system, and the efficiency of the sorting system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of garbage disposal, in particular to a construction garbage dry sorting system. Background technique [0002] With the rapid development of urban construction, the process of demolition and reconstruction has brought a large amount of construction waste, which can be divided into: old building demolition waste, construction site waste, decoration waste and building material production waste. The types of these construction waste Various, including sandstone blocks, concrete fragments, steel bars, waste wood and waste decoration materials. Due to the inclusion of various types of materials with different volumes and textures, their recycling often suffers from poor screening separation. [0003] For garbage such as soft packaging materials and small wooden boards that are entangled in sand, stones, concrete fragments, etc., the current sorting methods are mainly winnowing or water sorting. Sewage, causing ...

Due to the inclusion of various types of materials, varying in size and texture, their recycling often suffers from poor screening separation

[0003] For garbage such as soft packaging materials and small wooden boards that are entangled in sand, stones, concrete fragments, etc., the current sorting methods are mainly winnowing or water sorting. Sewage, causing additional sewage pollution. For example, in the patent: Mixed urban domestic waste resource treatment method (public number: CN1022319722), for light objects, plastic bags, paper, wood, leather, etc., manual sorting and classification are carried out. However, the efficiency of manual sorting is too low, the working environment is poor, and with the increase of workers' wages, the cost is gradually increasing
