Description

Technical Field

[0001] This utility model relates to the field of flotation machine technology, specifically to a flotation machine for anti-splash coal preparation. 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; those that float to the surface of the slurry are scraped off to form a froth product, while the rest remain in the slurry, thus achieving the purpose of separating minerals.

[0003] During the operation of the flotation machine, coal particles in the raw coal selectively adhere to the surface of air bubbles through the action of reagents, forming mineralized air bubbles. These coal particle-air bubble complexes rise to the liquid surface under the action of buoyancy and are eventually collected by the froth scraping mechanism, thereby obtaining high-purity clean coal. However, there is a key problem in the actual operation of existing flotation machines: because the slurry liquid level is the same as the height of the collection tank, during the violent stirring and air bubble bursting process, some unmineralized raw coal slurry is prone to splashing. This not only causes slurry overflow and pollutes the working environment, but more seriously, this splashed slurry will enter the collection tank along with the mineralized air bubbles, resulting in unsorted slurry mixed into the final product, which significantly reduces the purity and recovery rate of clean coal.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Please see Figure 1-4 As shown, a flotation machine for anti-splash coal preparation includes a flotation tank 1, and further includes:

[0023] A support frame 2 is fixed to the top of the flotation tank 1. An agitator 3 is fixedly connected to the top of the support frame 2. The agitator 3 includes a first motor 301. A feed pipe 4 is fixedly connected to one side of the flotation tank 1. Baffle frames 5 are fixedly connected to both the front and rear sides of the top of the flotation tank 1. A limit plate 6 is fixedly connected to one side of the top of the flotation tank 1.

[0024] The slurry discharge component 7 is fixed to one side of the baffle frame 5. The slurry discharge component 7 includes a second motor 701. A guide plate 8 is fixedly connected to one side of the inside of the flotation box 1. A perforated plate 11 is provided inside the flotation box 1. The agitator 3 is easily and stably supported by the support frame 2. The agitator 3 can agitate the coal material to form bubbles. These coal particle-bubble complexes rise to the liquid surface under the action of buoyancy and are eventually collected by the bubble scraping mechanism, thereby obtaining high-purity clean coal. The material is easily introduced into the inside of the flotation box 1 through the feed pipe 4. The baffle frame 5 can tilt the two sides of the slurry outlet position to prevent the slurry from splashing out from the two sides of the flotation box 1. The slurry discharge component 7 can discharge the bubble slurry to the outside of the flotation box 1 in conjunction with the guide plate 8.

[0025] A discharge port 9 is provided on one side of the inside of the flotation box 1. A buffer plate 10 is fixedly connected to one side of the inside of the flotation box 1. The discharge port 9 facilitates the flow of flotation slurry to the outside of the flotation box 1. The buffer plate 10 is located at the bottom of the inner cavity of the flotation box 1, which can provide a certain degree of isolation for the pressure of the rotating coal slurry and reduce the serious shaking of the upper bubbles caused by violent stirring.

[0026] Both first motors 301 are fixed to the top of the support frame 2. The output end of the first motor 301 extends through to the bottom of the support frame 2 and is fixedly connected to the transmission rod 302. The bottom of the transmission rod 302 is fixedly connected to the stirring paddle 303. By turning on the first motor 301, the transmission rod 302 can drive the stirring paddle 303 to rotate. At this time, the stirring paddle 303 will efficiently stir the coal material inside the flotation box 1.

[0027] A hydraulic rod 12 is fixedly connected to the top of the baffle frame 5. The piston end of the hydraulic rod 12 extends through to the bottom of the baffle frame 5 and is fixedly connected to the perforated plate 11. A limiting post 13 is fixedly connected to one side of the top of the perforated plate 11. The surface of the limiting post 13 is slidably connected to the inside of the support frame 2. The height of the perforated plate 11 inside the flotation box 1 can be adjusted by the hydraulic rod 12. By precisely controlling the height of the perforated plate 11, splashed slurry can be effectively blocked without interfering with the normal rise of mineralization bubbles. The limiting post 13 is fixed on the perforated plate 11. The surface of the limiting post 13 is slidably connected to the inside of the support frame 2, which can also improve the stability of the perforated plate 11 when it moves up and down.

[0028] The second motor 701 is fixed to one side of the baffle frame 5. The output end of the second motor 701 extends through to one side of the baffle frame 5 and is fixedly connected to the drive rod 702. The surface of the drive rod 702 is fixedly connected to the discharge plate 703. By turning on the second motor 701, the drive rod 702 and the discharge plate 703 can be driven to rotate, thereby pushing the slurry on the water surface to the discharge port 9 for flotation with the guide plate 8.

[0029] A cylinder 14 is fixedly connected to one side of the limiting plate 6. The piston end of the cylinder 14 passes through to one side of the limiting plate 6 and is fixedly connected to an insert plate 15. A slide rod 16 that is slidably connected to the inside of the limiting plate 6 is fixedly connected to one side of the insert plate 15. The cylinder 14 can drive the insert plate 15 to insert into the guide plate 8. When flotation is not required, it can prevent flotation foam from overflowing out of the discharge port 9. The slide rod 16 can improve the stability of the insert plate 15 when it moves and ensure the strength of the movement.

[0030] Working principle: First, the coal material is poured into the flotation tank 1 through the feed pipe 4. Then, by turning on the first motor 301, the transmission rod 302 drives the agitator 303 to rotate. At this time, the agitator 303 will efficiently agitate the coal material inside the flotation tank 1. The vortex generated by the material will impact the buffer plate 10, thereby reducing water flow sloshing. Subsequently, the bubbles rise, and the height of the perforated plate 11 inside the flotation tank 1 can be adjusted by the hydraulic rod 12. By precisely controlling the perforated plate 11... The height effectively blocks splashed slurry without interfering with the normal rise of mineralization bubbles. Then, turning on the second motor 701 drives the drive rod 702 and the discharge plate 703 to rotate, thus pushing the slurry on the water surface to the guide plate 8. At this time, the retracting cylinder 14 drives the insert plate 15 to disengage from the guide plate 8 and push it to the discharge port 9 for flotation. Furthermore, through the baffle frame 5 and the limiting plate 6, the top bubble outlet of the flotation box 1 can be tilted, thus effectively preventing the possibility of flotation slurry splashing out.
