Massive solid building waste sorting system based on multiple detection modes

Abstract

The invention relates to a massive solid building waste sorting system based on multiple detection modes. A sensor detection and recognition mechanism is composed of a conveyor belt and a sensor array with multiple detection functions; an industrial robot sorting mechanism is composed of a plurality of industrial robots and a plurality of sorting boxes; and a control system is connected with the sensor array and the industrial robots respectively, the sensor array carries out real-time detection, and the control system analyzes information collected by the sensor array and controls the industrial robots to sort massive solid building wastes in different types into corresponding sorting boxes. As for the massive solid building waste sorting system based on multiple detection modes, as a mechanical arm of each industrial robot is provided with a clamp, the massive solid building wastes on the conveyor belt are grabbed by the clamps and moved above the corresponding sorting boxes through movement of the mechanical arms, the clamps release the massive solid building wastes, and the sorted massive solid building wastes fall into the corresponding sorting boxes, so that effective sorting of the massive solid building wastes is realized.

Description

technical field [0001] The invention relates to a sorting technology for blocky solid construction waste, more specifically, to a sorting system for blocky solid construction waste based on multiple detection methods. Background technique [0002] Construction waste refers to solid waste generated during the construction process or during the maintenance and demolition of old buildings, including soil, stones, concrete blocks, broken bricks, wood, metal, pipes and electrical waste. Construction waste is considered as a misplaced resource, accounting for more than 90% of stones, concrete blocks, broken bricks, has stable physical and chemical properties, and is highly recyclable and circular. Professor Ma Baoguo of Wuhan University of Technology has proved that the main components of solid construction waste powder are silica, calcium oxide (calcium hydroxide, calcium silicate hydrate, calcium aluminate hydrate, calcium carbonate or anorthite in crushed stone, etc.) The cont...

AI Technical Summary

Problems solved by technology

The existing domestic construction waste sorting equipment has problems such as difficulty in separating different materials, especially technical problems such as high difficulty and high cost of different materials with similar specific gravity (typically, the specific gravity of concrete is 1.6, while the specific gravity of fired bricks is 1.3, Concrete and brick have similar specific gravity)

It is difficult and costly to achieve fine sorting of construction waste. How to effectively separate different materials such as bricks and concrete blocks from sand and gravel aggregates is a key technical difficulty that needs to be solved to improve the quality of resource reuse.

Moreover, construction waste wastes usually need to adjust the particle size to become uniform after passing through multiple mechanical stages before they can be effectively sorted. It is achieved by crushers or pulverizers, which consumes a lot of energy
