Description
The application relates to the technical field of dry sorting, for example, to an intelligent photoelectric sorting machine and a product separation method.
The intelligent dry separation technology is widely applied to the fields of coal, minerals, food, garbage, building materials and the like, and the separation mode is divided into two processes of identification and separation. The execution process is that the materials are flatly laid on the moving distributor, and the identification mechanism identifies each material in the modes of images, colors, X-ray transmission, X-ray fluorescence and the like. After the materials are identified, the falling tracks of the materials are changed through sorting, or through hitting of an elastic part or instantaneous high-pressure air blowing in the process that the materials are dropped from the tail end of the distributing device, so that the separation of the materials is realized.
In the related technology, the intelligent dry separation can only separate two products, and the separation of subsequent products is influenced due to the fact that the identification mechanism cannot effectively define the products after identification.
In addition, the X-ray sorting machine carries out detection based on the transmission high-low dual-energy X-ray detection principle, and due to the adoption of continuous spectrum X-rays, the high energy and the low energy are not clearly distinguished, and the overlapping influence is serious; and the thickness of the detection substance is not uniform. Although the influence caused by the thickness difference of part of detected materials is eliminated through an algorithm according to the information of two dimensions of high energy and low energy, the detection error caused by nonuniform material thickness is still very large, and especially the materials with similar atomic numbers cannot be effectively identified.
