Description

Technical Field

[0001] The present invention relates to the technical field of mineral processing, in particular to a magnetic levitation combined ore dressing machine and an ore dressing method. Background Art

[0002] Common mineral separation methods in the mineral processing process include magnetic separation and flotation. Usually, flotation and magnetic separation are carried out separately, first physical separation and then chemical separation, which does not make full use of time. Combining the two processes can save time and improve efficiency.

[0003] Conventional flotation and magnetic separation are carried out separately. Generally, magnetic separation is carried out first and then flotation. A lot of time is wasted in between and they cannot be carried out in parallel. Generally, the tailings after magnetic separation by magnetic separators need to be collected centrally. If flotation is required, they need to be transferred to the mineral processing device, which consumes a lot of energy and occupies a lot of space. Under normal circumstances, the two devices are not continuous, which is labor-intensive and time-consuming. Summary of the invention

[0071] The flotation scraper 5 includes a left flotation scraper and a right flotation scraper;

[0072] The top of the feeding top 3 is connected with the lifting device.

[0073] The lifting device drives the feeding top 3 to lift the inner tube 2 through the bracket 9;

[0074] The scrapers on the left and right sides of the scraper 5 are used for scraping. The gap between the scraper 5 and the tube 2 is set according to the pulp concentration and the foam thickness. The bottom end of the flotation scraper 5 is higher than the top end of the inner tube 2.

[0075] Preferably, the outer end of the flotation scraper 5 is connected to the bracket 9, and the bracket 9 drives the flotation scraper 5 to rotate around the connection point of the bracket 9 to scrape out the foam.

[0076] Preferably, a cavity is provided on the inner wall of the inner tube 2 , a magnetic pole 10 is provided in the cavity, and a coil 11 is wound around the magnetic pole 10 .

[0077] In order to achieve the purpose of adsorbing magnetic minerals, the outer wall of the tube 2 is uniformly magnetic by evenly installing magnetic poles and coils inside the tube 2.

[0089] Preferably, the belt is inclined downward;

[0090] The front end of the belt is arranged above the outer tube 1 .

[0091] A ore dressing method combining magnetic levitation and ore dressing machine, the ore dressing process is as follows:

[0092] The material is fed from the upper end of the feed top 3 and enters evenly through the feed port. The magnetic minerals are adsorbed by the outer wall of the tube 2, and the non-magnetic minerals fall into the storage tank; the storage tank is the gap between the outer tube 1 and the inner tube 2 and the lower part of the outer tube 1 and the inner tube 2. As the material increases, it enters the inner tube 2 for flotation.

[0093] The flotation reagent enters the inner tube through the pipeline to participate in flotation;

[0094] Since the ore is fed in stages, the time difference can be used to realize the discharge of magnetic concentrate. The lifting device is used to drive the feed top 3 to lift the tube 2 through the bracket 9. At this time, the magnetic minerals are adsorbed on the outer wall of the inner tube 2, and the magnetic minerals accumulate on the inner tube 2 to a certain thickness.

[0095] The front end of the conveyor belt 6 moves radially inward;

[0096] The support driving motor drives the support driving rack 12 to rotate through the support reducer;

[0097] The bracket 9 drives the inner tube 2 to rotate and pass through the magnetic separation scraper 4, and the magnetic separation scraper 4 above is used to scrape out the magnetic minerals and send them to the conveyor belt 6 to realize the recovery of the magnetic separation concentrate;

[0098] After the inner tube 2 is lifted up, the inner tube 2 rotates, and the magnetic separation scraper 4 moves inward; the magnetic separation scraper 4 moves toward the center and approaches the inner tube 2 to reduce the gap between the magnetic separation scraper 4 and the inner tube 2, thereby scraping out the magnetic concentrate adhering to the inner tube 2, and scraping out the magnetic concentrate at the position of the magnetic separation scraper 4, and the scraped magnetic concentrate directly falls onto the belt 6, and the magnetic concentrate is transported out by the belt 6.

[0099] The inner tube 2 stops rotating;

[0100] The feed top 3 is driven by the elevator to lower the barrel 2 to the initial position through the bracket 9;

[0101] The driving sleeve motor drives the driving sleeve rack 15 to rotate through the driving sleeve reducer;

[0102] The drive sleeve rack 15 drives the drive sleeve to rotate;

[0103] The driving sleeve 14 drives the flotation scraper 5 to rotate;

[0104] The froth of the flotation concentrate is located on the surface of the flotation machine, and the flotation scraper 5 rotates to scrape the froth outwards;

[0105] The flotation concentrate storage tank is arranged outside the outer tube; the flotation concentrate storage tank is connected with the conveying pipeline.

[0106] One end of the flotation scraper 5 is connected to the bracket 9 and is located above the inner tube 2, and is used to scrape out the flotation concentrate in the inner tube 2. The connection end of the scraper 5 is narrower, and the other end is wider. The narrower side is connected to the bracket 9, and the connection can drive the scraper 5 to rotate; the wider side can scrape out as much flotation concentrate as possible.

[0107] The left flotation scraper 5 moves counterclockwise;

[0108] The right flotation scraper 5 moves clockwise;

[0109] After the magnetic separation scraper 4 scrapes off the magnetic concentrate, the magnetic concentrate falls freely. The belt 6 plays the role of receiving the magnetic concentrate falling freely. After the magnetic concentrate falls on the belt 6, the belt rotates to transport the magnetic concentrate out. After the inner tube 2 is lifted up, the magnetic separation scraper 4 moves to the right and stops after scraping the magnetic minerals on the outer wall of the inner tube 2. The inner tube 2 rotates to the position of the magnetic separation scraper 4, and the magnetic minerals are scraped off.

[0110] The invention combines the magnetic levitation and ore dressing machine. After magnetic separation, the tailings directly enter the flotation tank and can directly carry out the next flotation. The time difference is well utilized, time is saved, the ore dressing cost is reduced, and the ore dressing efficiency is improved.

[0111] The above is only a preferred embodiment of the present invention, and does not limit the structure of the present invention in any form. Any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention are within the scope of the technical solution of the present invention.
