Problems solved by technology

This method is difficult to sort construction waste with similar size, color, and shape with high precision. It can only sort them in a coarse-grained manner. At the same time, the work of manual sorting is messy and dangerous, and the rational use of construction waste cannot be realized. and recycling purposes

Embodiment

[0023] The present invention provides an optical sorting and processing system for construction waste, which includes a conveyor belt 100, a detection device, a sorting device and a collection device.

[0024] The conveyor belt 100 is used to transport materials, which are unscreened construction waste, including mixed aggregates mainly composed of red bricks and concrete blocks, with a particle size of 20-60 mm, wherein the proportion of red bricks is 20-60 mm. 40%.

[0025] In addition, a drive motor 110 is also installed below the conveyor belt 100 to drive the conveyor belt 100 to be transported. In this embodiment, the material is conveyed from the left side of the conveyor belt 100, driven clockwise along the conveyor belt 100, and falls freely at the right end of the conveyor belt 100. whereabouts.

[0026] The detection device includes a line-scan camera 200 and an industrial computer 300. In this embodiment, the line-scan camera 200 is arranged on the upper right sid...

Abstract

The invention discloses an optical sorting processing system and a processing method for construction waste. The optical sorting processing system for construction waste comprise a conveyor belt, a detection device, a sorting device and a collection device, wherein the conveyor belt is used for conveying materials; the detection device comprises a linear array camera and an industrial personal computer; the linear array camera is arranged above one side of the conveyor belt; the industrial personal computer is connected with the linear array camera; the sorting device comprises a PLC system, an air pump and a blowing valve group; the PLC system is connected with the air pump and the blowing valve group; the blowing valve group is arranged below one side of the conveyor belt; the collectiondevice comprises a plurality of recovery boxes; the recovery boxes are arranged at one side of the blowing valve group; and the industrial personal computer is connected with the PLC system. According to the optical sorting processing system for construction waste, the linear array camera is matched with the industrial personal computer, the PLC system and the blowing valve group to sort and process the construction waste, the linear array camera collects picture information and feeds back the picture information to the industrial personal computer, the industrial personal computer analyzes and processes the picture information and sends an instruction to the PLC system, and the PLC system controls the blowing valve group to blow the falling materials into the corresponding recycling boxes, so that the sorting efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of construction waste sorting, in particular to an optical sorting system and processing method for construction waste. Background technique [0002] my country is the largest construction market in the world. The current construction volume exceeds half of the world's total. The amount of waste generated and discharged in urban construction is also growing rapidly. Among them, construction waste accounts for about 30%-40% of the total waste. However, the resource utilization rate of construction waste in my country is only about 5%. my country's construction waste treatment and resource utilization technology is lagging behind, and urban construction waste treatment mostly adopts direct landfill, which not only occupies land but also pollutes the environment, which is far behind developed countries. After sorting, removing or crushing many wastes in construction waste, such as concrete, steel, wood, etc., can be reus...
