Material separation method and device, controller and storage medium

Abstract

The invention provides a material separation method and device, a controller and a storage medium and relates to the technical field of material separation. The material separation method comprises the steps of obtaining a material characteristic of a material to be separated, recognized by a recognition system and positioned in a preset position on a material conveying device; according to the material characteristic of the material to be separated, determining a target spray-blowing device from a first spray-blowing device and a second spray-blowing and determining a target separation area from corresponding separation areas of the target spray-blowing device; and controlling gas supply equipment to provide a spray-blowing force, corresponding to the target separation area, for the target spray-blowing device so that the target spray-blowing device sprays and blows the material to be separated, conveyed to the edge position of the material conveying device, to the target separation area. As the first spray-blowing device and the second spray-blowing device have reverse spray-blowing directions, the materials can be accurately separated only by controlling the gas supply equipmentto provide the spray-blowing force, corresponding to the target separation area, for the target spray-blowing device; and therefore, the adaptability of the gas supply equipment to performance degradation or gas supply pressure change is improved.

Description

technical field [0001] The present invention relates to the technical field of material sorting, in particular to a material sorting method, device, controller and storage medium. Background technique [0002] As minerals continue to be mined, it is also essential to sort the mined minerals. For example, coal can be sorted manually, but this method wastes a lot of human resources and the sorting efficiency is low. Minerals are therefore also increasingly sorted by means of sorting devices. [0003] In the related technology, the sorting device can be equipped with a blowing mechanism on one side to precisely control the blowing force of the blowing mechanism, and the material is blown through the blowing mechanism so that the material enters different sorting areas. Realized the sorting of materials. [0004] However, in related technologies, it is necessary to accurately control the blowing force. When the performance of the blowing mechanism decreases or the air supply ...

Problems solved by technology

[0005] The object of the present invention is to provide a material sorting method, device, controller and storage medium for the deficiencies in the above-mentioned prior art, so as to solve the problem of accurate and error-free control of the blowing force in the related art, when the blowing mechanism When the performance drops or the air supply pressure fluctuates, it is easy for the injected material to enter other sorting areas, resulting in wrong sorting of the material and reducing the accuracy of the material sorting
