The invention discloses a construction waste brick and concrete aggregate sorting device and a construction waste brick and concrete aggregate sorting method. By adopting the powerful parallel computing capability of a field programmable gate array (FPGA) and a rapid image acquisition technology of a color image sensor, using image recognition and high-pressure nozzle blowing methods and combiningthe characteristics of construction waste aggregate, a constant light source system, a feeding buffer structure and a dust-removing design are organically combined together so as to form a novel construction aggregate sorting system. The device and the method which are provided by the invention solve the problem that the existing construction waste aggregate cannot be sorted and change the traditional construction waste treatment mode; furthermore, the device and the method enable large-scale promotion of a construction waste aggregate treatment process to be possible based on the principlesof low cost and high efficiency.
Description
technical field [0001] The invention relates to the field of environmental protection machinery and equipment, in particular to the technical field of construction waste resource utilization equipment, in particular to a construction waste brick and concrete aggregate sorting device and method. Background technique [0002] Construction waste is solid waste generated during the process of new building, renovation, expansion or demolition of buildings. With the rapid development of urbanization in our country, a large amount of construction waste is produced. At present, the comprehensive utilization rate of construction waste in my country is low, which has caused enormous pressure on resources and the environment. [0003] In construction waste, a considerable part of the product is a mixture of brick aggregate and concrete aggregate. Since the performance indexes of brick aggregate and concrete aggregate are very different, they are mixed together, and the utilization va...
