Description

Technical Field

[0001] This invention relates to the field of mineral processing technology, specifically to a magnetic levitation combined mineral processing machine and mineral processing method. Background Technology

[0002] Common mineral processing beneficiation methods include magnetic separation and flotation. Typically, flotation and magnetic separation are carried out separately, with physical beneficiation followed by chemical beneficiation. This process is not efficient in terms of time utilization. Combining the two processes can save time and improve efficiency.

[0003] Conventional flotation and magnetic separation are performed separately, usually with magnetic separation preceding flotation. This process wastes considerable time and cannot be done in parallel. Tailings from magnetic separation typically need to be collected centrally. If flotation is required before transferring the tailings to the mineral processing unit, it consumes a lot of energy and occupies a large area. Normally, the two processes are not conducted continuously, resulting in significant labor, time, and labor costs. Summary of the Invention

[0069] The magnetic separator scraper 4 is used to scrape the magnetic concentrate adhering to the outer wall of the outer cylinder 2.

[0070] A flotation scraper 5 is provided above the inner cylinder 2;

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

[0072] The top of the feeder is connected to the lifting device.

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

[0074] Both scrapers on the left and right sides of scraper 5 scrape ore. The gap between scraper 5 and cylinder 2 is set according to the slurry concentration and foam thickness. The bottom of flotation scraper 5 is higher than the top of inner cylinder 2.

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

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

[0077] To achieve the purpose of adsorbing magnetic minerals, the outer wall of cylinder 2 is uniformly magnetic by uniformly installing magnetic poles and coils inside cylinder 2.

[0078] The outer cylinder 1 prevents material spillage and also allows for thorough magnetic separation. This device enables simultaneous magnetic separation and flotation.

[0079] Preferably, the bracket 9 includes a left connecting bracket and a right connecting bracket;

[0080] The top of the bracket 9 is provided with a bracket drive rack 12, which is connected to the bracket drive gear 13;

[0085] A drive sleeve rack 15 is provided on the upper surface of the drive sleeve 13;

[0086] The drive sleeve rack 15 is connected to the drive sleeve gear 16;

[0087] The drive sleeve gear is mounted on the output shaft of the drive sleeve reducer;

[0088] The drive sleeve reducer is connected to the drive sleeve motor.

[0089] Preferably, the belt is inclined downwards;

[0090] The front end of the belt is positioned above the outer cylinder 1.

[0091] A mineral processing method combining magnetic levitation and a mineral processing machine, the mineral processing process is as follows:

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

[0093] Flotation reagents enter the inner cylinder through pipes to participate in flotation;

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

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

[0096] The bracket drive motor drives the bracket drive rack 12 to rotate through the bracket reducer;

[0097] The support 9 drives the inner cylinder 2 to rotate and pass through the magnetic separation scraper 4. The magnetic minerals are scraped out by the magnetic separation scraper 4 above and sent to the conveyor belt 6 to realize the recovery of magnetic separation concentrate.

[0098] After the inner cylinder 2 is lifted up, the inner cylinder 2 rotates, and the magnetic separation scraper 4 moves inward. The magnetic separation scraper 4 moves towards the center and approaches the inner cylinder 2, making the gap between the magnetic separation scraper 4 and the inner cylinder 2 smaller, thereby scraping off the magnetic concentrate adhering to the inner cylinder 2. The magnetic concentrate is scraped off at the position of the magnetic separation scraper 4 and falls directly onto the belt 6, which then transports it out.

[0099] Inner cylinder 2 stops rotating;

[0100] The elevator is used to lower the feed top 3 to the initial position via the bracket 9;

[0101] The drive sleeve motor drives the drive sleeve rack 15 to rotate via the drive sleeve reducer;

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

[0103] Drive sleeve 14 drives flotation scraper 5 to rotate;

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

[0105] The flotation concentrate storage tank is located outside the outer cylinder; the flotation concentrate storage tank is connected to the conveying pipeline.

[0106] One end of the flotation scraper 5 is connected to the support 9 and is located above the inner cylinder 2. It is used to scrape out the flotation concentrate in the inner cylinder 2. The connecting end of the scraper 5 is narrower and the other end is wider. The narrower side is connected to the support 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-side flotation scraper 5 rotates counterclockwise.

[0108] The right-side flotation scraper 5 rotates clockwise.

[0109] After the magnetic separator scrapes off the magnetic concentrate, it falls freely. The conveyor belt 6 serves to catch the falling magnetic concentrate. Once the magnetic concentrate lands on the conveyor belt 6, the belt rotates, transporting the magnetic concentrate out. After the inner cylinder 2 is lifted, the magnetic separator scrapes off to the right, scraping the magnetic minerals on the outer wall of the inner cylinder 2 before stopping. The inner cylinder 2 then rotates to the position of the magnetic separator scrapes off, and the magnetic minerals are scraped off.

[0110] The present invention is a magnetic levitation combined mineral processing machine. After magnetic separation, the tailings directly enter the flotation cell and can be directly subjected to subsequent flotation. This makes good use of the time difference, saves time, reduces mineral processing costs, and improves mineral processing efficiency.

[0111] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the structure of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the scope of the technical solution of the present invention.
