Description

Technical Field

[0001] This utility model relates to the field of flotation machine technology, and more specifically, to a flotation machine with adjustable liquid level. Background Technology

[0002] Flotation machine is short for flotation mineral processing machine. It refers to mechanical equipment that completes the flotation process. In the flotation machine, after the slurry is treated with reagents, it is stirred and aerated, so that some mineral particles are selectively fixed on 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, so as to achieve the purpose of separating minerals.

[0003] Based on the above, the inventors have discovered that existing flotation machines are not convenient for rapid and stable liquid level adjustment. When the liquid level is too high, the froth layer becomes thin, the secondary enrichment effect is poor, and unmineralized gangue particles easily enter the concentrate, leading to a decrease in concentrate grade. When the liquid level is too low, the froth layer becomes thick, and mineralized bubbles cannot be scraped out in time, resulting in concentrate loss. Therefore, in view of this, the inventors have studied and improved the existing structure to provide a flotation machine with adjustable liquid level, aiming to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a flotation machine with adjustable liquid level. This solution is equipped with an adjustment component with a cleaning function to clean the impurities filtered during the adjustment process, reduce the occurrence of clogging problems, and ensure the smooth operation of liquid level adjustment. In addition, a meshing component is set up so that the cleaning component rotates during the cleaning process, which improves the cleaning and anti-clogging effect. At the same time, the cleaning component has a simple structure and is easy to maintain and replace later.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A flotation machine with adjustable liquid level includes a flotation cell and a water tank. Two air guide pipes are fixedly connected to the middle of the flotation cell, and scrapers are fixedly connected to both sides of the flotation cell. A water inlet and a water outlet are opened at one end of the flotation cell, and a support frame is provided on the inner side of one end of the flotation cell. An adjustment motor is fixedly connected to the inner side of one end of the flotation cell, and a water inlet pump and a water outlet pump are fixedly connected to the top of the water tank.

[0009] The output end of the regulating motor is fixedly connected to a reciprocating lead screw, and a ball slider is sleeved on the outer side of the reciprocating lead screw. Both ends of the support frame are provided with toothed rings on their inner sides, and a cleaning roller is centrally engaged on the opposite surfaces of the two toothed rings.

[0010] Furthermore, the water tank is located outside the flotation cell, and a screen is fixedly connected to one end of both the water inlet and the water outlet, with the water inlet located above the water outlet.

[0011] Furthermore, the output end of the water inlet pump is fixedly connected to the water inlet hole, and the input end of the drain pump is fixedly connected to the drain hole.

[0012] Furthermore, the lower part of the ball slider is fixedly connected to the top of the support frame, and the connection between the ball slider and the support frame is slidably connected to one end of the flotation cell.

[0013] Furthermore, a movable ring is fixedly connected to one end of the toothed ring on the outer side, and the movable ring is movably connected to the support frame.

[0016] 3. Beneficial Effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This solution adjusts the flotation liquid level by using the water inlet and the drain hole. At the same time, the reciprocating screw of the motor is adjusted to rotate. The rotation of the reciprocating screw, in conjunction with the ball slider, causes the support frame to slide back and forth at one end of the flotation cell, thereby driving the cleaning roller to clean the screen outside the water inlet and the drain hole. Compared with the prior art, the adjustment component with cleaning function is set up to clean the impurities filtered during the adjustment process, reduce the occurrence of clogging problems, and ensure the smooth progress of the liquid level adjustment work.

[0019] (2) During the movement of the support frame, the two toothed rings mesh with the toothed blocks at both ends, and the toothed rings drive the cleaning roller to rotate, which improves the cleaning effect of the cleaning roller. Finally, the bolts facilitate the installation and removal of the cleaning roller and the toothed rings, and facilitate the replacement of the cleaning roller in the later stage. Compared with the existing technology, the meshing component is set up so that the cleaning component rotates during the moving cleaning process, which improves the cleaning and anti-clogging effect. At the same time, the cleaning component has a simple structure, which is convenient for later maintenance and replacement. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1-4 A flotation machine with adjustable liquid level includes a flotation cell 1 and a water tank 2. Two air guide pipes 3 are fixedly connected to the middle of the flotation cell 1, and scrapers 4 are fixedly connected to both sides of the flotation cell 1. A water inlet hole 5 and a drain hole 6 are opened at one end of the flotation cell 1, and a support frame 7 is provided on the inner side of one end of the flotation cell 1. An adjustment motor 9 is fixedly connected to the inner side of one end of the flotation cell 1, and a water inlet pump 10 and a drain pump 11 are fixedly connected to the top of the water tank 2.

[0028] The output end of the regulating motor 9 is fixedly connected to a reciprocating screw 13. A ball slider 14 is sleeved on the outer side of the reciprocating screw 13. Both ends of the support frame 7 are provided with toothed rings 15 on the inner side. A cleaning roller 16 is clamped in the center of the opposite face of the two toothed rings 15. When the regulating motor 9 is started, the reciprocating screw 13 is driven to rotate.

[0029] See Figure 1 The water tank 2 is located outside the flotation cell 1. A screen is fixedly connected to one end of the water inlet 5 and the drain hole 6. The water inlet 5 is located above the drain hole 6. The slurry is fed into the flotation cell 1 and aerated through the air pipe 3, so that some mineral particles selectively attach to the air bubbles and float to the top of the flotation cell 1. At the same time, the scraper 4 rotates to scrape off the foam product above the flotation cell 1, while the rest is retained in the slurry to achieve the purpose of separating minerals.

[0030] See Figure 1The output end of the water inlet pump 10 is fixedly connected to the water inlet hole 5, and the input end of the drain pump 11 is fixedly connected to the drain hole 6. The water inlet pump 10, in conjunction with the water inlet hole 5, delivers water into the flotation cell 1 to raise the liquid level. The drain pump 11, in conjunction with the drain hole 6, delivers the water inside the flotation cell 1 to the water tank 2 to lower the liquid level, thereby adapting to different flotation conditions.

[0031] See Figure 2 The lower part of the ball slider 14 is fixedly connected to the top of the support frame 7, and the connection between the ball slider 14 and the support frame 7 is slidably connected to one end of the flotation cell 1. The rotation of the reciprocating screw 13, in conjunction with the ball slider 14, causes the support frame 7 to slide back and forth at one end of the flotation cell 1, thereby driving the cleaning roller 16 to clean the screen outside the water inlet hole 5 and the drain hole 6, reducing the occurrence of clogging problems and ensuring the stability of liquid level adjustment.

[0032] See Figure 4 One end of the toothed ring 15 is fixedly connected to a movable ring, which is movably connected to the support frame 7. The movable ring acts as a limit to ensure the rotational stability of the toothed ring 15.

[0033] See Figure 3 Two sets of toothed blocks 8 are fixedly connected to the inner surface of one end of the flotation cell 1. Two toothed rings 15 are respectively engaged with the two sets of toothed blocks 8. During the movement of the support frame 7, the two toothed rings 15 are engaged with the toothed blocks 8 at both ends, and the toothed rings 15 drive the cleaning roller 16 to rotate.

[0034] See Figure 4 The toothed ring 15 and the cleaning roller 16 are connected by a threaded bolt 12. One side of the cleaning roller 16 is in contact with the water inlet 5. The bolt 12 facilitates the installation and removal of the cleaning roller 16 and the toothed ring 15, and makes it easy to replace the cleaning roller 16 later.

[0035] In operation: The slurry is fed into flotation cell 1, and agitated and aerated through the air pipe 3, causing some mineral particles to selectively adhere to the air bubbles and float to the top of flotation cell 1. Simultaneously, the scraper 4 rotates to scrape off the foam product above flotation cell 1, while the remainder remains in the slurry, achieving mineral separation. When liquid level adjustment is required, water is supplied to flotation cell 1 through water inlet pump 10 and water inlet 5 to raise the liquid level. Conversely, water is supplied to water tank 2 through drain pump 11 and drain 6 to lower the liquid level, thus adapting to different flotation conditions. Filtration is then performed by a screen. The starting adjustment motor 9 rotates the reciprocating screw 13. The rotation of the reciprocating screw 13, in conjunction with the ball slider 14, causes the support frame 7 to slide back and forth at one end of the flotation cell 1. This drives the cleaning roller 16 to clean the screen outside the water inlet 5 and the drain 6, reducing clogging and ensuring the stability of the liquid level adjustment. During the movement of the support frame 7, the two toothed rings 15 mesh with the toothed blocks 8 at both ends, causing the toothed rings 15 to drive the cleaning roller 16 to rotate, improving the cleaning effect of the cleaning roller 16. Finally, the bolts 12 facilitate the installation and removal of the cleaning roller 16 and the toothed rings 15, making it easy to replace the cleaning roller 16 later.
