[0057] A gas flow beneficiation method for protecting large scale graphite, including a gas flow beneficiation device for protecting large scale graphite as above, the processing steps are as follows:

[0058] Step one: a certain amount of ore is conveyed into the pulverizer 5 through the feeding port 6 for crushing, and the crushed ore falls onto the upper side of the sieve disc 17 through the discharge port 7;

[0059] Step two: start the motor 12 to drive the disc 13 to rotate, and through the fixed shaft 14 on one side of the disc 13 to slide in the through slot 16, make the connecting shaft 15 as a whole to make circular motion to drive the lower sieve disc 17 to reciprocate in the placing frame 11, screen the crushed ore, screen the ore that does not meet the sorting adjustment to the bottom of the bearing box 9 and through the discharge pipe 10 to collect, at the same time, the electric telescopic rod 22 is retracted, the placing frame 11 on one side is inclined as a whole, and the screened ore above the sieve disc 17 is transported into the rectangular cylinder 23;

[0060] Step three: start the motor 48, the motor 48 drives the pulley two 47 to rotate and drives the pulley one 45 to rotate through the belt 46, so that the conveyor belt 25 works in the rectangular cylinder 23, and the conveying frame 42 works at the same time, at this time, the ore of the previous process will fall on the wear-resistant rubber plate 26 on one side of the conveyor belt 25, the movement of the conveyor belt 25 will drive the ore to move downward, in this process, the booster pump 49 and the air extractor 40 will work at the same time, so that a continuous airflow space is formed in the rectangular cylinder 23, the ore on one side of the conveyor belt 25 is air flow sorted, and finally the ore falls above the conveying frame 42 and is conveyed to the outside of the equipment through the discharge plate 43.

[0061] The specific embodiments of the application are shown as follows: Figures 1-9

[0062] 1, by putting the ore into the feeding port 6, at this time, the ore is crushed by the crusher 5 and discharged from the discharge port 7 and falls into the sieve disc 17 below, at this time, the motor 12 drives the disc 13 to rotate, the disc 13 drives the fixed shaft 14 above to slide along the through slot 16, so that the connecting shaft 15 makes circular motion along one side of the disc 13, so that the connecting shaft 15 drives the sieve disc 17 to reciprocate as a whole in the bearing box 9 to screen, at the same time, the guide block 18 slides along the guide slot 19, which ensures the stability of the operation of the sieve disc 17, at this time, the ore above will screen the ore that does not meet the requirements and separate into the bearing box 9 below and be conveyed to the outside of the equipment through the discharge pipe 10 for collection, when the screening is completed, the electric telescopic rod 22 can be retracted to drive the sliding block 21 to slide along the sliding rail 20, so that the angle of the placing frame 11 is inclined, and the ore in the sieve disc 17 is poured and transported to the next process.

[0063] ​2、Through the last process, the ore is transported to the top of the rectangular cylinder 23, and the ore will fall to the top of the wear-resistant rubber plate 26 on one side of the conveying belt 25. At this time, the motor 48 drives the pulley two 47 to rotate and drives the pulley one 45 to rotate through the belt 46, so that the roller two 44 rotates and the conveying frame 42 works at the same time, so that the conveying belt 25 drives the wear-resistant rubber plate 26 to move downward, drives the ore to move to one side of the dust absorption plate 37, and forms a relatively sealed space. At this time, the air extractor 40 drives the dust collection cover 38 to absorb dust through the hose two 39, and the booster pump 49 blows air into the blowing cover 28 through the hose one 30 to increase the pressure, and the airflow is transported into the relatively sealed space formed by the wear-resistant rubber plate 26 and the dust absorption plate 37 through the filter screen 27. Through air extraction and internal airflow transportation, a flowing airflow is formed inside, and the internal fine scales can be transported into the dust collection box 41 by the air extractor 40. Because the spring 33 pushes the push rod 31 to slide in the sleeve 32, and the limiting block 36 slides in the limiting groove 35, the blowing cover 28 drives the wear-resistant rubber ring 29 to firmly adhere to one side of the conveying belt 25, so that the airflow can be concentrated through the filter screen 27. Finally, through the movement of the conveying belt 25, the ore can be continuously sorted by airflow, and because the conveying belt 25 continuously moves, the ore can slightly contact the surface of the dust absorption plate 37, so that the ore is turned inside, and finally falls onto the conveying frame 42 below and is transported to the outside of the equipment through the discharge plate 43 after the sorting is completed.
