Building garbage color sorting system

Abstract

The invention relates to a building garbage color sorting system, which comprises a material discharging buffer storage bin, a vibration feeder, a belt conveyor, an image acquisition system, a jet trace change system and an information processing and control system, wherein the observation area of the image acquisition system is arranged on a material moving trace limited outside the belt conveyor and is used for obtaining the image of a material in the observation area and converting into image digital information, and the information processing and control system respectively forms signal connections with the image acquisition system and the jet trace change system, and is used for receiving the image digital signal output by the image acquisition system and analyzing, recognizing the material having the color set by the image acquisition system, generating a control signal for the jet trace change system, and transmitting into the control device of the jet trace change system to control the jet trace change system to perform the corresponding jet action so as to achieve the sorting. The building garbage color sorting system of the present invention has advantages of simple structure, high yield, and accurate material judgment.

Description

technical field [0001] The invention relates to a color sorting system for construction waste, which can effectively sort out color materials set by an image collection system in construction waste, and is mainly used for color separation of construction waste. Background technique [0002] The main components of construction waste are gravel, debris, brick soil, concrete blocks, steel bars, door and window frames, etc. caused by building demolition, including a small amount of debris such as wood chips, rags, and plastics. To recycle these construction wastes, it is necessary to classify and select according to the surface color of the waste, so as to separate them for recycling. At present, the color sorting methods widely used are manual color sorting and photoelectric color sorting machine color sorting. The disadvantages of manual color sorting are slow speed, low efficiency, unstable quality, and high cost; photoelectric color sorters usually use Si photodiodes as lig...

AI Technical Summary

Problems solved by technology

The disadvantages of manual color sorting are slow speed, low efficiency, unstable quality, and high cost; photoelectric color sorters usually use Si photodiodes as light sensors to receive the reflected light of granular materials during the movement of granular materials, forming According to the electrical signal corresponding to the light intensity, the color of the granular material is judged according to the strength of the electrical signal, and then the air blowing device is controlled by the control system to blow out the airflow in the flow path of the granular material to blow off the unnecessary foreign matter. Compared with manual color sorting, this kind of color sorter has made great progress in efficiency and reliability

However, when a photoelectric color sorter is used, the dust interference in the construction waste will also affect the sorting accuracy of the color sorter.

In addition, limited by the structure of the color sorter, each feeding is limited, which also makes the sorting speed slower
