Description

Technical Field

[0001] This utility model relates to the field of flotation machine technology, specifically a flotation machine for gold ore beneficiation. Background Technology

[0002] A stirred flotation machine consists of a body, a mixing shaft inside the body, an impeller, an air inlet pipe, a motor, flotation blades, and a discharge port. After the minerals and reagents are mixed, the centrifugal force generated by the rotation of the impeller draws the liquid minerals into the mixing shaft. The liquid minerals are mixed with the air drawn in through the air inlet pipe to generate foam. The foam is then scraped off by the flotation blades to produce a foam product, which is used in the mining industry to screen tailings.

[0003] A search revealed a Chinese patent publication number, CN218796539U, which discloses a stirred flotation machine. The machine includes a body, a mixing shaft mounted on the inner wall of the body, an impeller mounted on the lower surface of the mixing shaft, an air inlet pipe fixedly connected to the arc surface of the mixing shaft, a motor mounted on one side of the body, flotation blades fixedly connected to the output end of the motor, the arc surface of the flotation blades rotatably connected to the body, a discharge port mounted on one side of the body, and a cleaning structure provided inside the body.

[0004] Although the aforementioned patent can clean residual slag on the inner wall, the flotation machine still has the following problems: In existing flotation machines, the thickness of the froth layer fluctuates due to changes in reagent dosage or process parameters. The fixed-height flotation blades are difficult to adapt to changes in the froth layer. When the froth layer is too thin, the flotation blades may not be able to effectively scrape the froth, resulting in a decrease in the recovery rate of useful minerals. When the froth layer is too thick, the flotation blades are prone to scraping below the liquid surface, carrying out too much slurry, affecting the grade and dewatering efficiency of the froth product. This limits the adaptability of the flotation machine to different working conditions and reduces the overall flotation effect. In view of the above, technological innovation is carried out on the basis of existing equipment. Utility Model Content

[0005] The purpose of this invention is to provide a flotation machine for gold ore beneficiation to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flotation machine for gold ore beneficiation, comprising a flotation machine, a fixed block fixedly connected to the top of the flotation machine, and sliding grooves respectively opened on both sides inside the fixed block. Sliding blocks are slidably connected inside the two sliding grooves, and rotating shafts are rotatably connected to the opposite sides of the two sliding blocks. A second motor is installed inside the sliding blocks, and the output end of the sliding blocks is fixedly connected to one end of the flotation blades. Flotation blades are fixedly connected to the surface of the rotating shafts. First threaded rods are rotatably connected inside the two sliding grooves, and the surface of the first threaded rods is threadedly connected to the inside of the sliding blocks.

[0007] Preferably, the fixed block has a transmission groove inside, and two sprockets are rotatably connected inside the transmission groove. A chain is driven to the surface of the sprockets, and the two sprockets are synchronously driven by the chain. The bottom of the two sprockets is fixedly connected to the top of the first threaded rod.

[0008] Preferably, a first motor is fixedly connected to the top of the fixing block, and the output end of the first motor is fixedly connected to one side of the sprocket.

[0009] Preferably, a filter frame is fixedly connected to one side of the flotation machine, and a filter screen is provided inside the filter frame.

[0010] Preferably, a second threaded rod is rotatably connected inside the filter frame, and a scraper is slidably connected inside the filter frame, with the interior of the scraper threadedly connected to the surface of the second threaded rod.

[0011] Preferably, a third motor is fixedly connected to one side of the filter frame, and the output end of the third motor is fixedly connected to one end of the second threaded rod.

[0012] Preferably, corrugated tubes sleeved on the surface of the second threaded rod are fixedly connected to both sides of the scraper, and the side of the corrugated tube away from the scraper is fixedly connected to the inside of the filter frame. Collection frames are provided on both sides of the filter frame.

[0013] Preferably, a connecting pipe is fixedly connected to the bottom of the filter frame, and a pump body is fixedly connected to one side of the connecting pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This flotation machine for gold ore beneficiation flexibly adjusts the relative position of the flotation blades and the slurry surface through the cooperation of the first threaded rod and the slider. For thick froth layers, the flotation blades can be raised appropriately to allow more time for the water and gangue to be removed from the froth, thereby obtaining a drier and higher-grade concentrate. For thin froth layers, the flotation blades can be lowered to ensure that the useful minerals attached to the bubbles can be recovered as soon as possible, improving the recovery rate and preventing them from falling off due to excessive foam residence time. At the same time, it enhances the versatility of the equipment and reduces user costs.

[0015] 2. This flotation machine for gold ore beneficiation effectively intercepts mineral particles in the froth through the combination of filter screen and scraper, preventing them from being directly discharged with the liquid, thus significantly improving the mineral recovery rate. At the same time, the collection frames on both sides collect the mineral particles, simplifying the mineral transfer process, improving production efficiency, reducing manual intervention, and lowering labor intensity and maintenance costs.

The surface of the first threaded rod 12 is threadedly connected to the inside of the slide block 10. By rotating the first threaded rod 12, the slide block 10 on the surface is driven to slide inside the slide groove 9. At the same time, by starting the second motor 11, the flotation leaf 6 on the surface of the rotating shaft 5 can float the foam while controlling the flotation height, making the flotation of foam more precise and effective.

[0019] The fixed block 2 has a transmission groove 13 inside, and two sprockets 14 are rotatably connected inside the transmission groove 13. The surface of the sprockets 14 is connected to a chain 15, and the two sprockets 14 are synchronously driven by the chain 15.

The top of the fixed block 2 is fixedly connected to the first motor 4, and the output end of the first motor 4 is fixedly connected to one side of the sprocket 14. By starting the first motor 4, the bottom sprocket 14 is driven to rotate, and at the same time, the two sprockets 14 are synchronously driven by the chain 15 on the surface.

[0020] A filter frame 3 is fixedly connected to one side of the flotation machine 1. A filter screen 21 is installed inside the filter frame 3. The filter screen 21 separates foam and mineral particles, allowing the liquid adhering to the foam to fall to the bottom of the filter screen 21. A second threaded rod 17 is rotatably connected inside the filter frame 3. A third motor 16 is fixedly connected to one side of the filter frame 3, and the output end of the third motor 16 is fixedly connected to one end of the second threaded rod 17. A scraper 19 is slidably connected inside the filter frame 3, and the interior of the scraper 19 is threadedly connected to the surface of the second threaded rod 17. Sleeves fitted onto the second threaded rod 17 are fixedly connected to both sides of the scraper 19. The corrugated tube 18 on the surface of the threaded rod 17 is fixedly connected to the inside of the filter frame 3 on the side away from the scraper 19. The corrugated tube 18 can protect the second threaded rod 17 and prevent it from being contaminated with foam and liquid, which would prevent it from being driven.

[0022] Working principle: For this type of gold ore beneficiation flotation machine, the grade of gold concentrate and the recovery rate of gold flotation are increased by adjusting the type and amount of reagents. Then, the first motor 4 is started, which drives the bottom sprocket 14 to rotate. At the same time, the two sprockets 14 are synchronously driven by the chain 15 on the surface, which drives the two first threaded rods 12 at the bottom to rotate. The sliders 10 on the surface of the first threaded rods 12 slide inside the chute 9 to control the flotation height. At the same time, the second motor 11 is started, which makes the flotation blades 6 on the surface of the rotating shaft 5 float the foam, making the flotation of foam more precise and effective.

[0023] After flotation, the foam falls onto the filter screen 21 inside the filter frame 3. Then, the third motor 16 is started, causing the second threaded rod 17 to drive the scraper 19 on the surface of the filter screen 21 to slide and collect the mineral particles on both sides of the scraper inside the collection frame 20. The slurry carried by the foam is then transported back to the bottom of the filter frame 3 through the connecting pipe 7 to the inside of the flotation machine 1 for re-flotation.
