[0002] Coal flotation equipment is a mechanical device that realizes the froth flotation process and selects the target minerals from the ore. It mainly generates negative pressure through the centrifugal effect of the rotation of the impeller. On the one hand, it inhales sufficient air to mix with the slurry, and on the other hand, it stirs the slurry and mixes the drug. At the same time, it refines the foam, makes the minerals adhere to the foam, float to the surface of the slurry, and then form mineralized foam.

[0003] The existing coal flotation equipment has the following points that need to be improved when in use: 1. The existing stirring structure and aeration device of the coal flotation equipment cannot be adapted, so that when the coal is stirred, the air cannot be fully mixed with the slurry, affecting the efficiency of coal flotation;

[0004] 2. After the minerals in the existing coal flotation equipment are adhered to the foam, although it can be discharged, in actual use, it is not convenient to automatically push the foam floating on the surface of the slurry into the coal flotation collection box, which is relatively inconvenient to operate;

[0005] 3.

[0018] Furthermore, a method of coal flotation equipment comprises the following steps:

[0019] S1: When flotating coal, first turn on the motor 1, which drives the threaded rod to rotate through the output end. The rotation of the threaded rod drives the cover plate to drop to contact with the annular plate. The sealing gasket on the upper end of the annular plate can ensure the reliability of the cover plate after being fixed. At this time, the material is poured into the flotation box through the feed pipe. At this time, the driving structure drives the hollow stirring shaft to rotate, and the hollow stirring shaft drives the hollow stirring plate to rotate, so as to stir the material. At the same time, gas is injected into the hollow stirring shaft until it is discharged through the air outlet on the side of the hollow stirring plate, so that the air and the slurry are fully mixed. On the other hand, the slurry is stirred and mixed with the drug, and the foam is refined at the same time, so that the minerals are bonded to the foam and float to the surface of the slurry to form mineralized foam;

[0020] S2: Clamp the fixing sleeve on the upper end of the hollow rotating block, and then fix the fixing sleeve with the flange and bolts. At this time, inject air through the air inlet pipe, and the air will enter the hollow stirring shaft along the hollow rotating block. At the same time, turn on the motor 2 in the installation box 1. The motor 2 drives the driving gear to rotate through the output end, and the driving gear drives the driven gear to rotate. The driven gear drives the hollow stirring shaft to rotate. The hollow stirring shaft drives the hollow rotating block to rotate inside the fixing sleeve, thereby avoiding the problem of the hollow stirring shaft being stuck.

[0021] S3: In order to facilitate the scraping of coal flotation materials into the coal flotation collection box body, the electric cylinder is turned on at this time, and the electric cylinder drives the push rod to rise, and the rise of the push rod drives the top plate to rise. At this time, the coal flotation materials will exceed the upper end of the flotation box body, and then the motor three is turned on, and the motor three drives the screw rod one to rotate through the output end, and the rotation of the screw rod one drives the slide plate to slide, and the sliding of the slide plate drives the sliding of the L-shaped connecting rod, and the sliding of the L-shaped connecting rod drives the scraper to slide, so that the coal flotation materials are scraped into the coal flotation collection box body;

[0022] S4: When the screw rod 1 rotates, it drives the connecting gear 1 to rotate, the connecting gear 1 rotates and drives the flexible toothed belt to rotate, the flexible toothed belt rotates and drives the connecting gear 2 to rotate, the connecting gear 2 rotates and drives the screw rod 2 to rotate, thereby improving the stability of the sliding process of the skateboard;

[0023] S5: When the coal flotation collection box body is used, the universal wheel drives the coal flotation collection box body to move, the coal flotation collection box body drives the connecting block to slide, the connecting block slides and drives the card block to insert into the card slot inside the card seat, and then cooperates with the fixing component 1 and the card hole to realize the connection and fixation of the coal flotation collection box body and the flotation box body;

[0024] S6: When the card block is inserted into the card slot, the card block drives the card pin to slide, and the card pin squeezes the square limit plate, and the square limit plate drives the spring to compress and make the card pin embedded in the square slot. When the card hole is aligned with the card pin, the spring rebounds, thereby driving the card pin to insert into the card hole, thereby realizing the connection and fixation between the coal flotation collection box body and the flotation box body. When the coal flotation collection box body needs to be disassembled, the adjustment block inside the adjustment slot is slid, and the adjustment block drives the card pin from the inside of the card hole, so that the coal flotation collection box body can be disassembled;

[0025] S7: When installing the filter box, place the filter box inside the coal flotation collection box body until the filter box is placed on the upper end of the annular partition, and then cooperate with the fixing component 2 and the fixing hole to achieve the installation and fixation of the filter box;

[0026] S8: Before installing the filter box, pull the handle, the handle pulls the pull rod, the pull rod pulls the circular limit plate and the fixing rod, and drives the second spring to compress. At this time, the filter box is placed on the upper end of the annular partition, and then the handle is released, and the second spring rebounds, thereby driving the fixing rod to be inserted into the fixing hole to achieve the installation and fixation of the filter box. At this time, the coal flotation product can be filtered through the filter net at the lower end of the filter box.

[0029] 2. The present invention is provided with an automatic scraping mechanism for coal flotation materials. The setting of the mechanism can automatically scrape the coal flotation materials in the flotation box to the inside of the coal flotation collection box, thereby completing the collection of the coal flotation materials.
