Abstract
Description
Technical Field
[0001] This utility model relates to the field of mineral processing technology, and in particular to a clean flotation device for mineral processing. Background Technology
[0002] In gold ore beneficiation, flotation has become one of the mainstream processes for gold ore beneficiation due to its excellent collection ability for fine and micro-fine gold ore and strong mineral selectivity. During flotation, after the slurry is adjusted with reagents and aerated, the useful minerals adhere to the bubbles to form mineralized foam that floats to the surface of the liquid. Then, the foam is collected and enriched by the foam scraping mechanism. Therefore, the performance of the flotation machine is directly related to the gold recovery index and the economic benefits of beneficiation.
[0003] Existing flotation machines typically include flotation cells, agitation mechanisms, aeration devices, and froth scraping mechanisms. The froth scraping mechanism consists of a rotating shaft and scrapers fixed on both sides. Through the continuous rotation of the scrapers, the mineralized foam on the surface of the slurry is scraped into the concentrate tank, thereby achieving the collection of foam products.
[0004] However, since the slurry often contains sticky minerals or residual reagents, after a long period of scraping and foaming operations, minerals are easily adhered and accumulated on the surface of the scraper. This not only reduces the effective working area of the scraper and decreases the scraping efficiency, but may also increase the operating load of the scraper and affect the stability of the equipment due to the hardening of the adhering substances. Utility Model Content
[0005] To address the aforementioned problems, this invention provides a clean flotation device for mineral processing that enables online high-pressure cleaning of the scraper. This design allows for periodic automated rinsing of the scraper surface without shutting down the machine or disassembling the scraper, effectively removing adhering minerals, keeping the scraper clean, ensuring continuous and stable scraping efficiency, and significantly improving the continuity and cleanliness of flotation operations.
[0006] The technical solution adopted to solve the above-mentioned technical problems is: a clean mineral processing flotation device, including a flotation machine, a scraper, a rotating tube, a water guide pipe, water spray holes and nozzles. The rotating tube is rotatably connected to the upper side of the flotation machine. The scraper is connected to both sides of the rotating tube.

The electric push rod is connected to the side wall of the flotation machine, and the output end of the electric push rod is connected to the rotary joint.
[0009] Furthermore, it also includes a connector, a locking component, a positioning component, and a clamping plane. The connector is fixedly connected to the output end of the electric push rod.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0021] like Figures 1-7 As shown in the figure, this embodiment provides a clean flotation device for mineral processing, including a flotation machine 1, a scraper 2, a rotating tube 3, a water guide pipe 4, water spray holes 5, and nozzles 6. The rotating tube 3 is rotatably connected to the upper part of the flotation machine 1. The scraper 2 is connected to both sides of the rotating tube 3. The water guide pipe 4 is slidably connected inside the rotating tube 3. One end of the water guide pipe 4 is open and the other end is closed. The water guide pipe 4 rotates with the rotating tube 3. Water spray holes 5 are opened on both sides of the rotating tube 3. The water spray holes 5 are aligned with the scraper 2. Nozzles 6 are evenly connected to the water guide pipe 4. The nozzles 6 cooperate with the water spray holes 5.
[0022] In the above embodiments, by connecting the scraper 2 to both sides of the rotating tube 3 and setting an axially sliding water guide pipe 4 inside the rotating tube 3, and in conjunction with the structure of the nozzle 6 and the water spray hole 5, online high-pressure cleaning of the scraper 2 is achieved. This design can automatically wash the surface of the scraper 2 periodically without stopping the machine or disassembling the scraper 2, effectively removing adhering minerals, keeping the scraper 2 clean, ensuring the continuous and stable scraping efficiency, extending the service life of the scraper 2, reducing the frequency of manual maintenance, and significantly improving the continuity and cleanliness of the flotation operation.
[0023] Specifically, it also includes a sealing block 7. The sealing block 7 is evenly connected to the water guide pipe 4. The sealing block 7 slides with the water guide pipe 4 and is used to seal and block the spray hole 5. The nozzle 6 is located inside the sealing block 7. The sealing block 7 has holes for the nozzle 6 to be installed.
[0024] In the above embodiments, the sealing block 7 is made of rubber. By setting the sealing block 7, during normal operation, the sealing block 7 just blocks the water spray hole 5, preventing the slurry from entering the rotating pipe 3 through the water spray hole 5 to the greatest extent. During cleaning, the sealing block 7 is moved away with the water guide pipe 4, and the nozzle 6 is aligned with the water spray hole 5 to spray water. This structure protects the cleanliness of the nozzle 6 when it is not in operation.
[0025] Specifically, it also includes a splined shaft 8, an electric push rod 12, a water pump 9, a hose 10, a rotary joint 11, and an electric push rod 12. The splined shaft 8 is fixedly connected to the closed end of the water guide pipe 4, and the splined shaft 8 is splinedly matched with the rotating pipe 3. The water pump 9 is connected to the side wall of the flotation machine 1. The first end of the hose 10 is connected to the water outlet end of the water pump 9. The rotary joint 11 is connected to the second end of the hose 10 and the open end of the water guide pipe 4. The electric push rod 12 is connected to the side wall of the flotation machine 1, and the output end of the electric push rod 12 is connected to the rotary joint 11.
[0026] In the above embodiments, by setting the spline shaft 8, the water guide pipe 4 can rotate with the rotating pipe 3. The water pump 9 pumps the cleaning water to the hose 10, which is then sent to the water guide pipe 4 by the rotary joint 11 and finally sprayed out by the nozzle 6. The electric push rod 12 drives the rotary joint 11 to move forward and backward, thereby making the water guide pipe 4 move axially in the rotating pipe 3, realizing the switching of the cleaning mode. The structure is simple and reliable, and the control is precise.
[0027] Specifically, it also includes a connector 13, a clip 14, a positioning element 16, and a clamping plane 17. The connector 13 is fixedly connected to the output end of the electric push rod 12. The clip 14 is slidably connected to the connector 13 through a spring 15. The positioning element 16 is fixedly sleeved on the rotary joint 11. The positioning element 16 has clamping planes 17 on both sides, and the clip 14 is clamped in the position of the clamping plane 17.
[0028] In the above embodiments, the positioning member 16 is fixed on the rotary joint 11, and clamping planes 17 are opened on both sides of it. The locking member 14 is slidably connected to the connecting member 13 through the spring 15 and is locked in the clamping plane 17 to prevent the rotary joint 11 from rotating with the water pipe 4. This quick-release structure facilitates the installation and disassembly of the rotary joint 11 and is convenient for daily maintenance and replacement.
[0029] Specifically, it also includes a motor 18 and a pulley set 19. The motor 18 is connected to the upper side of the flotation machine 1, and the pulley set 19 links the output shaft of the motor 18 with the rotating tube 3.
[0030] In the above embodiments, the rotation of the rotating tube 3 is achieved by the motor 18 driving the pulley group 19.
[0031] The working principle of this utility model is as follows: When the flotation operation is carried out, the motor 18 starts and drives the rotating tube 3 to rotate through the belt pulley group 19. The rotating tube 3 drives the scrapers 2 on both sides to rotate continuously, scraping the foam on the surface of the flotation tank into the concentrate tank. At this time, the water guide pipe 4 rotates synchronously with the rotating tube 3 through the spline shaft 8. The sealing block 7 on the water guide pipe 4 blocks the water spray hole 5 of the rotating tube 3. The nozzle 6 and the water spray hole 5 are misaligned, the water path is blocked, and the slurry will not enter the interior of the rotating tube 3. When the surface of scraper 2 needs to be cleaned, the electric push rod 12 is activated, pushing the connector 13, the clamp 14, the positioning member 16 and the rotary joint 11 to move axially. The rotary joint 11 drives the water guide pipe 4 to slide synchronously in the rotating pipe 3, so that the sealing block 7 on the water guide pipe 4 moves, the nozzle 6 is aligned with the water spray hole 5, and at the same time, the hose 10 is adaptively bent to accommodate the displacement. When the water pump 9 is started, the cleaning water is sent into the water pipe 4 through the hose 10 and the rotary joint 11, and then sprayed out at high speed through the nozzle 6 and the spray hole 5. The water flow is directed at the surface of the scraper 2 for high-pressure rinsing, effectively removing the adhering minerals on the scraper 2. After cleaning, the electric push rod 12 reverses its direction, causing the water guide pipe 4 to reset, the sealing block 7 to re-seal the spray hole 5, the water circuit is closed, and the equipment returns to normal foam scraping state. The entire process does not require manual intervention or shutdown.
[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
