Description

Technical Field

[0001] This utility model belongs to the field of concentrate flotation technology, specifically relating to a concentrate flotation device. Background Technology

[0002] A flotation machine is a mechanical device that completes the flotation process. In a flotation machine, after the slurry has been treated with reagents, it is agitated and aerated, causing some mineral particles to selectively adhere to the air bubbles and float to the surface of the slurry to be scraped off to form a froth product. The rest remain in the slurry, thus achieving the purpose of separating minerals.

[0003] After multi-stage flotation, the concentrate flows into the concentrate pool through different pipelines. Because the grade of the concentrate varies after each stage of flotation, the analytical test results are prone to large errors compared with the actual results, which is not conducive to the adjustment and optimization of reagents, processes, and procedures. Utility Model Content

[0004] This utility model provides a concentrate flotation device, which can restrict the position of settling solids by means of anti-impact columns and protruding blocking balls. After three mixing stages, the concentrate is uniformly mixed. The concentrate after each stage of flotation flows into the mixing tank from different pipelines, resulting in more uniform mixing, improved sampling accuracy, and benefits from reagent saving and improved recovery rate.

[0005] This utility model provides the following technical solution: a concentrate flotation device, including a buffer mixing tank, two partition plates are fixedly connected inside the buffer mixing tank, the two partition plates are distributed vertically, and there is a mixing tank, an intermediate tank and a feeding tank between the two partition plates and the buffer mixing tank. After the concentrate flows into the mixing tank, it flows into the intermediate tank from the lower gap. When the liquid level in the intermediate tank is higher than the lower partition plate, it flows into the feeding tank from above the partition plate. A number of baffle anti-impact columns are fixedly connected to the bottom of the buffer mixing tank, and the baffle anti-impact columns and the bottom of the inner side of the buffer mixing tank have a bottom cavity.

[0006] The upper partition plate has a space for buffering and mixing of the concentrate within the space.

[0007] Among them, several of the partition anti-impact columns are evenly distributed, and there is a gap between every two partition anti-impact columns.

[0008] The partition anti-impact column is slidably connected with several protruding position limiting balls, and the outer end face of the protruding position limiting balls is located outside the partition anti-impact column.

[0009] The partition anti-impact post has an installation hole, and the protruding position restricts the ball from slidingly connecting within the installation hole.

[0010] The protruding position restricts the outer wall of the ball to be fixedly connected with a spring, one end of which is fixed in the mounting hole.

[0011] The bottom cavity is connected to the mixing tank, the intermediate tank and the feeding tank, and coarse particles are deposited in the bottom cavity.

[0012] The beneficial effects of this utility model are: Two partition plates are fixedly connected inside the buffer mixing tank. The two partition plates are distributed vertically. Between the two partition plates and the buffer mixing tank, there are mixing tanks, intermediate tanks, and discharge tanks. After the concentrate flows into the mixing tank, it is first buffered and mixed in the upper partition tank. It then flows into the intermediate tank from the lower gap. When the liquid level in the intermediate tank is higher than the lower partition plate, it flows into the discharge tank from above the partition plate. At the same time, the position of the settling solids can be restricted by the baffle anti-impact column and the protruding position limiting ball. After three mixing stages, the concentrate is uniformly mixed. The concentrate after each flotation stage flows into the mixing tank from different pipelines, making the mixing more uniform, improving the sampling accuracy, and facilitating reagent saving and improved recovery rate.

[0015] Please see Figures 1-4 The present invention provides the following technical solution: it includes a buffer mixing tank 1, and two partition plates 11 are fixedly connected inside the buffer mixing tank 1. The two partition plates 11 are distributed vertically. Between the two partition plates 11 and the buffer mixing tank 1, there is a mixing tank 14, an intermediate tank 13 and a discharge tank 12. After the concentrate flows into the mixing tank 14, it flows into the intermediate tank 13 from the lower gap. When the liquid level in the intermediate tank 13 is higher than the lower partition plate, it flows into the discharge tank 12 from the top of the partition plate. Several baffle anti-impact columns 2 are fixedly connected to the bottom of the buffer mixing tank 1. The baffle anti-impact columns 2 and the bottom of the inner side of the buffer mixing tank 1 have a bottom cavity 15.

[0016] In this embodiment: the buffer mixing tank 1 is open-topped, with two iron plates 11 separating the upper and lower parts, dividing the buffer mixing tank 1 into three parts. Two partition plates 11 are fixedly connected inside the buffer mixing tank 1, positioned vertically. Between the two partition plates 11 and the buffer mixing tank 1 are a mixing tank 14, an intermediate tank 13, and a discharge tank 12. The upper partition plate 11 has a partitioned space where the concentrate is buffered and mixed. After the concentrate flows into the mixing tank 14, it is first buffered and mixed in the upper partitioned tank, and then flows into the intermediate tank 13 through the lower gap. When the liquid level in the intermediate tank 13 is higher than the lower partition plate 11, it flows into the discharge tank 12 from above the partition plate 11. The position of the settling solids can be restricted by the action of the baffle anti-impact column 2 and the protruding position limiting baffle ball 21. Under the action of the protruding position limiting baffle ball 21, the settled fixed particles can come into contact with the protruding position limiting baffle ball 21, compressing the position of the protruding position limiting baffle ball 21, which is conducive to passing between the two baffle anti-impact columns 2. The material located in the bottom cavity 15 is restricted by the space and the baffle anti-impact column 2 and the protruding position limiting baffle ball 21, which slows down the flow rate and impact of the incoming material and prevents the bottom settling solids from being directly stirred up. After three mixing, the concentrate is uniformly mixed. The concentrate after each stage of flotation flows into the mixing tank 14 from different pipelines, making the mixing more uniform, improving the sampling accuracy, and facilitating reagent saving and improved recovery rate.

[0017] Several baffle columns 2 are evenly distributed, with a gap between each pair of baffle columns 2; coarser and heavier particles can pass through the gap between two baffle columns 2 and settle in the bottom cavity 15.

[0018] Several protruding position limiting balls 21 are slidably connected inside the anti-impact column 2. The outer end face of the protruding position limiting balls 21 is located outside the anti-impact column 2. The anti-impact column 2 has a mounting hole 22. The protruding position limiting balls 21 are slidably connected in the mounting hole 22. A spring 23 is fixedly connected to the outer wall of the protruding position limiting balls 21. One end of the spring 23 is fixed in the mounting hole 22. The spring 23 limits the position of the protruding position limiting balls 21. When the particles falling from the upper space do not come into contact with the particles, they can remain in their original position. The settled fixed particles can come into contact with the protruding position limiting balls 21, compressing the position of the protruding position limiting balls 21, which is conducive to the passage between the two anti-impact columns 2.

[0019] The bottom cavity 15 is connected to the mixing tank 14, the intermediate tank 13 and the discharge tank 12. Coarse particles are deposited in the bottom cavity 15. The material in the bottom cavity 15 is restricted by space and the baffle anti-impact column 2 and the protruding position limiting ball 21, which slows down the flow rate and impact of the incoming material and prevents the solids that have settled at the bottom from being directly stirred up.

[0020] The working principle and usage process of this utility model are as follows: Two partition plates 11 are distributed vertically. Between the two partition plates 11 and the buffer mixing tank 1, there is a mixing tank 14, an intermediate tank 13, and a discharge tank 12. The upper partition plate 11 has a partitioned space. The concentrate is buffered and mixed in the partitioned space. After the concentrate flows into the mixing tank 14, it is first buffered and mixed in the upper partitioned tank, and then flows into the intermediate tank 13 from the lower gap. When the liquid level in the intermediate tank 13 is higher than that of the lower partition plate 11, it flows into the discharge tank 12 from above the partition plate 11. At the same time, the sedimentation and solidification can be restricted by the action of the baffle anti-impact column 2 and the protruding limiting baffle ball 21. Under the influence of the protruding position limiting ball 21, the fixed particles of the sediment can contact the protruding position limiting ball 21, compressing the position of the protruding position limiting ball 21, which facilitates the passage between the two baffle anti-impact columns 2. The material located in the bottom cavity 15 is restricted by the space and the baffle anti-impact columns 2 and the protruding position limiting ball 21, which slows down the flow rate and impact of the incoming material and prevents the direct flushing of the solids that have settled at the bottom. After three mixing stages, the concentrate is uniformly mixed. The concentrate after each stage of flotation flows into the mixing tank 14 from different pipelines, making the mixing more uniform, improving the sampling accuracy, and facilitating reagent saving and improved recovery rate.
