Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0027] Such as Figure 1-Figure 6 As shown, a coal gangue material sorting device based on terahertz identification according to the present invention includes a feed inlet 1, a sorting water tank 2, an identification mechanism 3, a scrubbing mechanism 5, a water outlet hole 7, and a coal storage bin 10. One end of the water selection tank 2 is provided with a feed port 1, and the bottom of the feed port 1 is connected with a scrubbing mechanism 5, which can wash off the coal mixed on the gangue, and a discharge hole 7 is installed on the top side of the feed port 1, which can discharge water. Coal is washed and sorted. The other end of the sorting water tank 2 is provided with a coal storage bunker 10, which can temporarily store coal lumps, and ...

Abstract

The invention relates to the technical field of coal gangue sorting, in particular to a coal gangue material sorting device based on terahertz recognition. The coal gangue material sorting device comprises a feeding port, a sorting water tank, a recognition mechanism, a washing mechanism, water outlet holes and a coal storage bin. The feeding port is formed in one end of the sorting water tank. The bottom of the feeding port is connected with the washing mechanism. A row of water outlet holes are formed in one side of the top of the feeding port. The coal storage bin is arranged at the other end of the sorting water tank. A coal and water mixing bin is arranged at the end, close to the coal storage bin, in the sorting water tank. One side of the sorting water tank is connected with the recognition mechanism. According to the coal gangue material sorting device, gangue with coal is conveyed and screened out through the recognition mechanism, then through usage of the washing mechanism and a washing push plate, a rotating plate reciprocates to sufficiently extrude and wash the gangue, coal waste is reduced, the tedious steps of manual operation are avoided, the workload of operators is relieved, repeated operation is conducted in cooperation with the washing mechanism, and coal and dust attached to the surface of the gangue can be cleaned away.

Description

technical field [0001] The invention relates to the technical field of coal gangue sorting, in particular to a coal gangue material sorting device based on terahertz identification. Background technique [0002] Coal gangue is solid waste discharged during the coal mining process and coal washing process. It is a black-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal formation process. Including the excavation gangue during the roadway excavation, the gangue extracted from the roof, floor and interlayer during the mining process, and the gangue picked out during the coal washing process. Coal washing is an indispensable process for deep coal processing. It is directly mined from the mine Raw coal is called raw coal. Raw coal is mixed with many impurities during the mining process, and the quality of coal is also different. Coal with small internal ash content and large internal ash content are mixed together. Coal was...
