Problems solved by technology

There are some problems that need to be solved in the existing sorting equipment: the stacking of bricks and concrete makes the sensor unable to judge correctly; the equipment requires that the identification process and the sorting process be carried out at the same time, but the sorting process is often due to the processing speed of the processor. Slower than the recognition time, it is difficult to accurately control the time; high equipment cost, not durable, etc.

Embodiment Construction

[0039] The present invention will be further described below through specific embodiments.

[0040] A sorting system for construction waste, capable of quickly sorting bricks and concrete. refer to figure 1 , figure 2 , including silo 1, baffle plate 2, feeding conveyor belt 3, dispersion conveyor belt 4, image acquisition device, pneumatic nozzle device 6, host computer 7, brick conveyor belt 8 and concrete conveyor belt 9. The silo 1 is used to store the mixture of crushed concrete and bricks to be sorted. The particle size range of the broken concrete and bricks is 30-50mm, the bricks are red, and the concrete is gray. The feeding conveyor belt 3 is inclined upwards, its starting end is below the outlet of the feed bin 1, and its end is positioned above the starting point of the dispersion conveyor belt 4, and the speed of the feeding conveyor belt 3 is slower than that of the dispersion conveyor belt 4, so as to A unit volume of material is dispersed over a larger area...

Abstract

The invention provides a construction waste sorting method and system. The construction waste storing method comprises the following steps: conveying a mishmash through a dispersing conveying belt; acquiring an image of the mishmash conveyed by the dispersing conveying belt, and processing to obtain the content of bricks in the mishmash as well as the position of each brick; and conveying the bricks arriving at the tail end of the dispersing conveying belt to a brick conveyor belt, and conveying the rest particles to another conveyor belt, thus realizing waste sorting. With the adoption of the method and the system, the bricks and concrete can be quickly automatically sorted; the recognizing process is performed earlier than the separating process, so that the sorting time can be accurately controlled; the cost is low; in addition, additional maintenance is avoided; the method and the system are applicable to the actual production environment.

Description

technical field [0001] The invention relates to the field of image detection and recognition, in particular to a sorting method and system for construction waste. Background technique [0002] With the development of urban construction in our country, construction waste disposal has become a severe environmental problem. At present, the level of resource utilization of construction waste in my country is low, and the reuse of construction waste is limited to simple treatment, resulting in resource waste, soil and groundwater pollution and other environmental problems. Vigorously promoting the resource utilization of construction waste is an inevitable choice for my country's sustainable development. Developed countries in Europe and the United States have long-term experience and technical reserves in domestic and industrial waste sorting technologies: electromagnetic sensors can distinguish whether they contain metal elements, near-infrared spectroscopy can distinguish dif...
