Description

Technical Field

[0001] This utility model relates to the field of flotation machine technology, and more specifically, to a stirred paddle flotation machine. Background Technology

[0002] A flotation machine, short for flotation mineral processing machine, refers to the mechanical equipment 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, float to the surface of the slurry, and be scraped off to form a froth product, while the rest remain in the slurry, thus achieving the purpose of separating minerals.

[0003] A search revealed that utility model patent CN217569175U discloses a flotation machine stirring device that circulates mineral slurry. The device includes a flotation machine body with three stirring rods installed inside. An mounting plate is installed at the lower end of each stirring rod, and a stirring paddle is slidably connected to the lower surface of the mounting plate. A separation paddle is installed on the surface of the flotation machine body. A limiting device is provided on the side of each stirring paddle near the mounting plate. The limiting device includes three fixing blocks, each fixedly connected to the side of the three stirring paddles near the mounting plate. A screw is threaded into each fixing block, and a positioning rod is fixedly connected to the end of the screw near the mounting plate. This patent solves the problem that after prolonged use of the flotation machine, the mineral slurry adhering to the stirring paddle easily solidifies, and the increased weight of the stirring paddle due to excessive accumulation can overload the motor, thus affecting the service life of the flotation machine.

[0004] However, the aforementioned patents have the following shortcomings: although the agitator can be disassembled and cleaned, the agitator is generally located at the bottom of the flotation cell of the flotation machine, making it inconvenient to remove the disassembled agitator. In addition, it is difficult to clean the slurry on the separation paddle using scrapers. Therefore, we propose an agitator flotation machine. Utility Model Content

[0031] In this embodiment, the end of the water inlet pipe 17 is connected to an external water pipe so that the cleaning water is introduced into the spray pipe 33 and the cleaning water is sprayed out from the nozzle 18 so as to clean the scraper 21 and at the same time rinse the inner cavity of the flotation tank 2 and the stirring blade 11.

[0032] For details, please refer to Figure 1 and Figure 3 The scraping mechanism 12 includes a fourth motor 20 fixedly installed on the side of the housing 1. The output shaft of the fourth motor 20 is fixedly connected to a rotating rod 19. The rotating rod 19 passes through the inner cavity of the two flotation cells 2. Two scrapers 21 are fixedly connected to the outside of the rotating rod 19 and located in the inner cavity of the flotation cell 2.

[0033] In this embodiment, the fourth motor 20 drives the rotating rod 19 and the scraper 21 to rotate, and the scraper 21 sweeps out the flotation material.

[0034] For details, please refer to Figure 1 , Figure 5 and Figure 6The drive mechanism 9 includes a stirring tube 22 rotatably connected to the support plate 8 and a second motor 23 fixedly installed on the top surface of the support plate 8. The output shaft of the second motor 23 is fixedly sleeved with a first synchronous pulley 24. The top end of the stirring tube 22 is fixedly sleeved with a second synchronous pulley 25. A synchronous belt 26 is connected between the second synchronous pulley 25 and the first synchronous pulley 24. The bottom end of the stirring tube 22 extends into the inner cavity of the flotation tank 2 and is fixedly sleeved with a mounting post 27. A mounting sleeve 10 is sleeved on the outside of the mounting post 27. The inner diameter of the mounting sleeve 10 is equal to the outer diameter of the mounting post 27. Multiple screw holes 28 are opened on the outside of the mounting post 27. Multiple mounting holes 29 are opened on the outside of the mounting sleeve 10. Bolts 30 are sleeved in the inner cavities of the multiple mounting holes 29. The ends of the multiple bolts 30 are threaded into the inner cavities of the screw holes 28 respectively.

[0035] In this embodiment, the mounting sleeve 10 is fixedly installed on the outside of the mounting column 27 by the cooperation of the screw hole 28, the bolt 30 and the mounting hole 29. In addition, the top end of the stirring tube 22 is connected to the air supply pipe so that gas can be introduced into the inner cavity of the flotation cell 2 through the stirring tube 22 to generate bubbles for flotation.

[0039] In this embodiment, the inner wall of the lifting box 3 is used to limit the lifting column 6, so that the lifting column 6 can only move along the axial direction of the screw 5.

[0040] Working principle: When flotation is performed on the ore, gas is introduced into the inner cavity of the flotation cell 2 through the stirring pipe 22. The stirring pipe 22 is started to drive the first synchronous wheel 24 to rotate. Through the transmission between the first synchronous wheel 24, the synchronous belt 26 and the second synchronous wheel 25, the stirring pipe 22, the mounting sleeve 10 and the stirring blade 11 are driven to rotate. The stirring blade 11 is used to stir the ore, so that the material moves to the top with the air bubbles. In addition, the fourth motor 20 is started to drive the rotating rod 19 and the scraper 21 to rotate, sweeping out the ore that floats to the top, thus realizing the flotation of the ore.

[0041] When it is necessary to clean the residual ore on the scraper 21 and the rotating rod 19, water is introduced into the inner cavity of the spray pipe 33 through the water inlet pipe 17, and the water is sprayed out from the nozzle 18. In addition, the third motor 15 is started to drive the spray pipe 33 and the nozzle 18 to rotate, changing the direction of the water sprayed from the nozzle 18. On the one hand, the scraper 21 and the rotating rod 19 are washed, and on the other hand, the inner cavity of the flotation cell 2 and the stirring blade 11 are washed.

[0042] When it is necessary to disassemble the mounting sleeve 10 and the stirring blade 11 for cleaning, start the first motor 4 to drive the screw 5 to rotate. Through the threaded engagement between the screw 5 and the lifting column 6, the lifting column 6, the lifting plate 7, the support plate 8, the stirring tube 22, the mounting sleeve 10 and the stirring blade 11 are moved upwards to lift the mounting sleeve 10 and the stirring blade 11 to the top of the housing 1. At this time, remove the nut 32 from the external thread seat 31 and remove the bolt 30 from the mounting hole 29 and the screw hole 28 so that the mounting sleeve 10 and the stirring blade 11 can be removed for cleaning.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
