Specific embodiments

[0017] Embodiment 1

[0018] As Figures 1 to 5As shown in the figure, the present utility model discloses a new type of flotation purification device. The technical solution adopted is as follows: it includes a flotation tank 1. At the left top of the flotation tank 1, a feeding pipe 2 and a reagent pipe 4 are symmetrically arranged before and after.

By operating the blower 15, the blower 15 blows air into the flotation tank 1 through the air pipe 16, causing a large number of bubbles to form in the slurry, which helps the flotation of graphite particles in the slurry. At the bottom of the air pipe 16, one-way valves 17 are fixedly installed respectively. Through the setting of the one-way valves 17, the phenomenon of gas reflux during the flotation process can be prevented, ensuring the stable generation and floating of bubbles. Above the flotation tank 1, an L-shaped top frame 7 is provided. The left end of the bottom of the L-shaped top frame 7 is fixedly connected to the left end of the top of the flotation tank 1. The right end of the bottom of the L-shaped top frame 7 is fixedly connected to a second support plate 9 provided at the right end of the top of the flotation tank 1. At the front and rear ends of the middle of the second support plate 9, connecting shafts 10 are rotatably installed respectively. At the middle of the connecting shafts 10, flotation plates 11 are arranged in an equidistant circumferential array. The left ends of the connecting shafts 10 are respectively rotatably connected to a first support plate 8 provided at the top left inside the flotation tank 1. A power unit 5 provided at the left end of the top of the L-shaped top frame 7 is drivingly connected to the left end of the connecting shaft 10. The power unit 5 includes a motor 51, a stirring shaft 52, a worm 53, a worm gear 54 and stirring blades 55. The stirring shaft 52 is rotatably installed at the left end of the top of the L-shaped top frame 7. The top end of the stirring shaft 52 is fixedly connected to the output shaft of the motor 51 fixedly installed at the top of the L-shaped top frame 7. At the bottom of the stirring shaft 52, stirring blades 55 are welded. By operating the motor 51, the output shaft of the motor 51 drives the stirring blades 55 through the stirring shaft 52 to stir the slurry, so as to fully mix the flotation reagent and the slurry. At the top of the stirring shaft 52, a worm 53 is provided, and the worm 53 meshes with the teeth on the worm gear 54 fixedly installed at the left end of the connecting shaft 10 respectively. During the rotation of the stirring shaft 52, the worm 53 can drive the worm gear 54 to rotate relatively, so that the worm gear 54 drives the flotation plates 11 to scrape the foam layer at the top of the flotation tank 1 through the connecting shafts 10 at the same time. At the bottom of the L-shaped top frame 7, a cleaning unit 6 is provided. The cleaning unit 6 includes a liquid inlet pipe 61, a connecting pipe 62, a shunt pipe 63 and a spray head 64. There are two shunt pipes 63, and the shunt pipes 63 are symmetrically arranged before and after at the bottom of the L-shaped top frame 7. The left and right ends of the shunt pipe 63 are respectively fixedly connected to the first support plate 8 and the second support plate 9. At the bottom of the shunt pipe 63, spray heads 64 are arranged in an equidistant array. The right end of the top of the shunt pipe 63 is respectively communicated with the connecting pipe 62 provided at the right end of the top of the L-shaped top frame 7. At the middle of the right end of the connecting pipe 62, a liquid inlet pipe 61 is provided. When cleaning is required, connect the liquid inlet pipe 61 to an external cleaning liquid pipeline.The cleaning liquid can enter the shunt pipe 63 through the liquid inlet pipe 61 and the connecting pipe 62 respectively, and be evenly sprayed on the flotation plate 11 by the spray head 64 at the bottom of the shunt pipe 63, thereby realizing the automatic cleaning of the flotation plate 11. A collection assembly is arranged at the outer top of the flotation tank 1. The collection assembly includes a collection hopper 12, a collection box 13 and a discharge pipe 14. There are two collection hoppers 12, which are symmetrically arranged in the front and back on the outside of the notches arranged at the top of the front and back sides of the flotation tank 1 respectively. The right ends of the collection hoppers 12 are respectively communicated with the inside of the collection box 13 arranged at the bottom of the right side of the flotation tank 1. The bottom of the rear end of the collection box 13 is provided with a discharge pipe 14. Through the collection hoppers 12 arranged symmetrically in the front and back, the floating graphite foam layer can be collected simultaneously from the front and back sides of the flotation tank 1, avoiding the accumulation and overflow of the foam layer, ensuring the continuity and stability of the purification process. At the same time, the connection design between the collection hopper 12 and the collection box 13 enables the graphite foam layer to flow smoothly into the collection box 13, facilitating subsequent discharging and purification treatment. It also includes a controller 3, which is fixedly installed at the left end of the top of the front side of the flotation tank 1. The output end of the controller 3 is electrically connected to the input ends of the motor 51 and the blower 15, and the input end of the controller 3 is electrically connected to the output end of an external power supply. Through the setting of the controller 3, it is convenient for the staff to control the motor 51 and the blower 15 respectively.

[0019] Working principle of the present utility model: During use, the slurry containing graphite to be flotated is injected into the flotation tank 1 through the feeding pipe 2. Meanwhile, an appropriate amount of flotation reagent is added to the flotation tank 1 through the reagent pipe 4. Then, the motor 51 is started through the controller 3. The output shaft of the motor 51 drives the stirring blades 55 through the stirring shaft 52 to stir the slurry, so as to fully mix the flotation reagent and the slurry, and promote the dispersion of the material particles, creating favorable conditions for the subsequent flotation process. Secondly, the blower 15 is started through the controller 3. The blower 15 blows air into the flotation tank 1 through the air pipe 16, causing a large number of bubbles to form in the slurry. Since the slurry is mixed with the reagent, the graphite therein has good floatability, and then adheres to the bubbles and floats to the top of the flotation tank 1 with the bubbles. The impurities have a larger density or different surface properties and cannot adhere to the bubbles, so they remain in the slurry. Then, as the materials at the top of the flotation tank 1 gradually accumulate to form a foam layer containing graphite, during the rotation of the stirring shaft 52, the worm 53 at its top drives the worm wheel 54 to rotate relatively, so that the worm wheel 54 drives the flotation plates 11 through the connecting shafts 10 respectively to scrape the foam layer at the top of the flotation tank 1 towards the collection hopper 12 simultaneously. The collection hopper 12 is arranged outside the notch at the top of the front and rear sides of the flotation tank 1, and can effectively collect the scraped graphite-containing foam layer. After the graphite foam layer enters the collection hopper 12, it will flow into the collection box 13 along the guidance of the collection hopper 12. Finally, the purified graphite material can be discharged through the discharge pipe 14 at the bottom of the rear end of the collection box 13, thus completing the entire flotation purification process. In addition, in order to keep the flotation tank 1 and the flotation plates 11 clean, the device is also provided with a cleaning unit 6. When cleaning is required, the liquid inlet pipe 61 is connected to an external cleaning liquid pipeline, so that the cleaning liquid can enter the shunt pipe 63 through the liquid inlet pipe 61 and the connecting pipe 62 respectively, and is evenly sprayed on the flotation plates 11 by the nozzles 64 at the bottom of the shunt pipe 63, thereby realizing the automatic cleaning of the flotation plates 11.
