[0002] Most of the existing fluorite purification requires the use of flotation machines, which are short for flotation concentrators and refer to mechanical equipment that completes the flotation process. In the flotation machine, the pulp treated with reagents is stirred and aerated so that some of the mineral particles are selectively fixed on the bubbles; the particles that float to the surface of the pulp are scraped out to form foam products, and the rest are retained in the pulp to achieve the purpose of separating minerals. There are many structural forms of flotation machines, and the most commonly used is the mechanical stirring flotation machine.

[0016] Preferably, the spiral scraping plate is on the inner side of the processing barrel, and the height of the spiral scraping plate from the bottom surface of the processing barrel is 1.1 times the height of the upper end surface of the processing barrel from its bottom surface.

[0017] Preferably, the method for using the processing equipment for fluorite purification comprises the following steps:

[0018] S1: The ground raw materials are transported into the processing barrel through the feed pipe, and gas is transported to the inside of the rotating tube through the air intake pipe. Then, the transmission motor drives the transmission gear to rotate so that the inner gear ring drives the rotating ring to rotate on the outside of the frame. Under the action of the connecting rod, the rotating tube is driven to rotate counterclockwise. The telescopic rod on the side of the rotating tube deflects away from the central axis of the rotating tube under the action of centrifugal force, pulling the plug plate to move to the outside of the rotating tube. The opening amount between the four plug plates in the rotating tube is regulated according to the rotation speed of the rotating tube, and the deflection angle of the telescopic rod corresponds to the rotation speed of the rotating tube. The deflection of the telescopic rod pulls the folding frame to unfold, and the spiral groove rod moves to the outside of the through groove. The spiral groove rod drives the folding frame to deflect under the limit of the protrusion, thereby increasing the area of ​​the folding frame stirring the raw materials in the processing barrel;

[0019] S2: The rotating tube rotates counterclockwise to drive the driven gear to rotate clockwise, so that the inner ring gear drives the outlet pipe to rotate clockwise to stir the raw materials transported to the processing barrel. At the same time, the gas in the rotating tube is discharged through the one-way air valve on the outlet pipe. The bubbles blown out of the outlet pipe are broken up with the help of the rotating folding frame and evenly dispersed in the raw materials in the processing barrel. The spiral scraper plate rotates counterclockwise to push the fluorite powder floating on the surface of the raw material to the surrounding areas in a ring-shaped divergent manner, and push the fluorite powder floating on the raw material into the filtering track;

[0020] Fluorite powder flows in the filter track, and the excess water in the fluorite powder is filtered out into the receiving track through the filter track;

[0021] S3: When the rotating ring rotates, the slider on the side of the plug rod slides in the ring groove, driving the plug rod to move up and down on the rotating ring, and the scraping ball fits inside the filter track and slides.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In the present invention, the rotating tube is driven to rotate counterclockwise by a transmission motor, and the telescopic rod on the side of the rotating tube is driven to deflect away from the central axis of the rotating tube under the action of centrifugal force, and the plug plate is pulled to move to the outside of the rotating tube. The opening amount between the four plug plates in the rotating tube is regulated according to the rotation speed of the rotating tube. When the telescopic rod is deflected and the folding frame is pulled to fold and unfold, when the spiral groove rod moves to the outside of the through groove, the spiral groove rod drives the folding frame to deflect under the limitation of the protrusion, thereby increasing the area of ​​the folding frame stirring the raw materials in the processing barrel, better breaking up the bubbles blown out of the air outlet pipe, increasing the area where the bubbles adhere to the fluorite powder in the raw material, making the fluorite powder better float to the surface of the raw material, and ensuring the flotation efficiency of the device.

[0024] In the present invention, the rotating tube rotates counterclockwise to drive the driven gear to rotate clockwise, so that the inner ring gear drives the air outlet pipe to rotate clockwise to stir the raw materials transported to the processing barrel. At the same time, the gas in the rotating tube is discharged through the one-way air valve on the air outlet pipe, ensuring that the gas is more evenly dispersed in the raw materials in the processing barrel, so that the fluorite powder in the raw materials can better follow the bubbles to float on the surface of the raw materials. At this time, the spiral scraper plate rotates counterclockwise to push the fluorite powder floating on the surface of the raw materials to the surrounding areas in a ring-shaped divergent manner, and push the fluorite powder floating on the raw materials into the filtering track.

[0025] In the present invention, since the filter track is spiral, the fluorite powder will flow in the filter track, which is convenient for users to collect the fluorite powder, and the excess water in the fluorite powder can be filtered out into the receiving track through the filter track, reducing the time required for subsequent devices to dry the fluorite powder.

[0026] In the present invention, when the rotating ring rotates, the slider on the side of the insertion rod is driven to slide in the ring groove, and the insertion rod is driven to move up and down on the rotating ring, ensuring that the scraping ball is stably fitted and slid inside the filter track, avoiding the fluorite powder after flotation purification from adhering to the filter track, thereby ensuring the convenience of users in collecting fluorite powder.
