Combined device capable of achieving virtual multichannel parallel sorting of coal and gangue

Abstract

The invention discloses a combined device capable of achieving virtual multichannel parallel sorting of coal and gangue. The combined device is composed of multiple independent sorting devices. Each sorting device corresponds one part of area of a conveying belt. The multiple sorting devices are jointed in parallel to cover the whole conveying belt. A recognition device mounted at the front end ofthe conveying belt recognizes the coal and the gangue distributed on the conveying belt, and position coordinate signals of the gangue are sent to a controller of the device. The device is mounted atthe tail of the conveying belt. When the gangue falls down, the device stretches out of moving supporting plates in the gangue corresponding area to receive the falling gangue, and the gangue rolls down to a gangue belt along the moving supporting plates. If coal briquettes fall down, the moving supporting plate returns to the initial position, and the coal briquettes fall down to a coal briquette conveying belt. In this way, parallel sorting of multiple coal briquettes and gangue blocks on the conveying belt is achieved.

Description

technical field [0001] The invention relates to a combination device for virtual multi-channel parallel sorting of coal and gangue, which sorts coal lumps and gangue lumps mixed and distributed on a conveyor belt, sorts the coal lumps to an independent coal lump belt for transportation, and sorts the gangue lumps. Pick up on another gangue transport belt. Background technique [0002] A large amount of gangue is entrained in the process of coal mining, and the separation of gangue is an important link in coal mine production. In the dry sorting method of coal gangue, there are many ways to separate mixed gangue blocks from coal blocks. Some use nozzles to blow off gangue, and some use electromagnets to separate mechanisms. [0003] The patent CN201610818861.X is an automatic coal gangue sorting system and method. The description is that the controller controls the first high-speed solenoid valve or the second high-speed solenoid valve to open when the gangue passes through ...

AI Technical Summary

Problems solved by technology

[0005] The above two technologies can only divide one conveyor belt into two regional passages on the left and right at most. For coal mines, the size of most coal and gangue is between 10 and 300, and more than 5 belts will be distributed on a 1-meter-wide belt at the same time. The coal stones in the middle will not be able to use the above two methods for effective sorting

Therefore, in actual production, the sorting efficiency will be greatly reduced by using the above two methods
