[0026] refer to Figure 2 A support frame 13 is provided at the bottom of the outer tank body 3 , and the inner wall of the support frame 13 is fixedly connected to the surface of the inner tank body 1 .

[0027] By providing the support frame 13, the flotation device can be supported and fixed to prevent it from tilting or even falling.

[0028] refer to Figure 2 The bottom of the support frame 13 is fixedly connected with a spacer 14. There are three spacers 14 evenly distributed on the bottom of the support frame 13. The spacers 14 have elasticity and vibration reduction capabilities.

[0029] By providing the spacer 14 , the friction force at the bottom of the support frame 13 can be increased to prevent the support frame 13 from moving when impacted by external forces.

[0030] refer to Figure 2 A fixing ring 15 is fixedly connected to the surface of the feeding pipe 9 , and the bottom of the fixing ring 15 is fixedly connected to the top of the mixing pipe 8 .

[0031] By providing the fixing ring 15, the connection portion between the feed pipe 9 and the mixing pipe 8 can be reinforced to prevent it from being subjected to excessive force, causing it to become loose or even fall off.

[0033] By providing the guide plate 16 , the discharge port 12 can be extended to facilitate the discharge of materials.

[0034] refer to Figure 5 The bottom of the inner wall of the outer tank body 3 is provided with an oblique angle 17, and the oblique angle 17 cooperates with the discharge port 12 to discharge the material quickly.

[0036] The working principle and use process of the utility model are as follows: the overall device is mainly composed of a feeding system consisting of a feed pipe 9 and a nozzle 10, an inflation system consisting of a mixing pipe 8 and an air guide pipe 11, a spraying system consisting of a water inlet pipe 6 and a top cover 4 and a spray head 5, an inner tank body 1, a discharge tank 2, an outer tank body 3, and a lower flushing pipe 7. During use, the high-pressure slurry is driven into the interior of the mixing pipe 8 through the feed pipe 9. During the driving process, the slurry pressure energy is converted into a high-speed jet through the nozzle 10, forming a jet in the sealed mixing pipe 8. Negative pressure draws air in through the air guide pipe 11, causing the slurry jet to wrap around the gas and enter the lower flush pipe 7. Due to the high turbulence of the fluid, the gas is divided into countless tiny bubbles and continuously collides and adsorbs with the mineral particles, completing the mineralization process. The mineralized bubbles surge out from the bottom of the lower flush pipe 7, and the bubbles carrying the concentrate rise to the surface of the slurry inside the inner tank 1 to form a foam layer. The foam rises, is flushed by the spray system, and is discharged into the outer tank 3 and flows to the discharge port 12 for recovery. The tailings slurry then flows down to the discharge trough 2 for discharge, completing the sorting. In addition, this device has the following characteristics during the sorting process: (1) Small bubble diameter, high gas capacity, large bubble specific surface area, and good bubble dispersion. (2) Short mineralization time and large processing capacity. The bubbles are dense, have a large carrying capacity, a fast floating speed, and a short movement distance. The flotation time is shorter than that of a conventional flotation machine. ⑶ The stirring intensity is high, and the mineralized area is mainly concentrated in the lower flush pipe 7. In a narrow space, the high-speed jet, negative pressure suction, high-intensity shear and turbulence increase the collision probability of fine mineral particles and bubbles, and the fine particle capture ability is strong. ⑷ The slurry sorting environment is good. The slurry adjustment and bubble mineralization process are completed in one step in the lower flush pipe 7. It is located in different parts from the foam rising area, concentrate area, tailings area, etc., and does not interfere with each other, so the sorting environment is good. ⑸ The mineral processing efficiency is high, and one device can replace one or even several flotation operations. ⑹ Energy saving and consumption reduction. The equipment has no rotating parts, few wearing parts, low maintenance costs, high equipment operating rate, and saves more electricity than conventional flotation machines. This avoids the low flotation efficiency and high electricity consumption of existing flotation machines, making it easy to use.

[0037] In summary, when the present invention is used, under the action of the structures such as the inner tank body 1 and the outer tank body 3, the mineral processing efficiency of the flotation device can be increased, energy can be saved and consumption can be reduced, and the low flotation efficiency and high electricity consumption of the existing flotation machine can be avoided, thereby making it easy to use and solving the problems of low efficiency and high energy consumption.
