Description

Technical Field

[0001] The utility model relates to the technical field of cavitation jets, in particular to a cavitation water jet grinding and flotation device. Background Art

[0002] Graphite is an important branch of carbon materials and an important strategic resource. Large flake graphite in graphite has a wide range of uses, few resources, and high value. It is an indispensable and important material in many domestic economic fields. However, the grade of flake graphite ore is low. In order to obtain high-grade flake graphite, the pre-mixed water jet is currently used to dissociate flake graphite through a multi-stage tapered friction shear cavitation water jet nozzle, making full use of the lamellar structure characteristics, external structure characteristics and mechanical properties of flake graphite. The flake graphite is dissociated mainly by tensile stress dissociation, supplemented by friction stress and shear stress dissociation, which is easy to remove fine-grained gangue on the surface of flake graphite, reduces the damage of large graphite flakes, and improves the particle size and grade of large flake graphite.

[0003] At present, when the cavitation water jet grinding and flotation device is in use, air and flotation agent enter the mixing tube through the suction pipe, and then mix with the flake graphite slurry ejected at high speed from the multi-stage tapered friction shear cavitation water jet nozzle to form a gas-liquid-solid three-phase slurry. The air, flotation agent and flake graphite slurry are only assisted in mixing by changing the pipe diameter in the mixing tube, which requires a large length of the pipe, ultimately resulting in a long pipe and spoiler components and occupying a large space, and a poor mixing effect.

[0007] Furthermore, a transmission shaft is fixedly installed on one side of the outer surface of the small pulley, and the transmission shaft extends through the interior of the waterproof shell to the outside and is fixedly connected to the rotating shaft. The transmission shaft and the waterproof shell rotate in a sealed manner, which can prevent the liquid in the mixing tube from leaking into the waterproof shell.

[0008] Furthermore, the plurality of inclined hole plates all comprise circular plates, and the circular plates are rotatably sleeved on the outer surface of the rotating shaft and fixedly connected to the mixing tube. The outer surface of the circular plates is provided with a plurality of penetrating inclined holes, which have the function of changing the direction and separating the mixed liquid.

[0009] Furthermore, a protective shell is fixedly connected to the outer surface of the mixing tube, and the motor is fixedly installed on an inner wall of one side of the protective shell. The protective shell supports the motor, which is beneficial to the installation of the motor. It also protects the motor to prevent the motor from being damaged by the external environment.

[0010] Furthermore, a medium air connecting pipe is fixedly passed through one side of the outer surface of the mixing tube, which is conducive to the medium air entering the mixing tube.

[0011] Furthermore, a flotation agent connecting pipe is fixedly passed through one side of the outer surface of the mixing tube, which is conducive to the flotation agent entering the mixing tube.

[0012] Beneficial effects of the utility model:

[0013] When the utility model is in use, the cavitation water jet grinding and flotation device increases the flow rate of the mixed slurry of medium air, flotation agent and flake graphite slurry through the arranged mixing tube, motor, waterproof shell, transmission component, rotating shaft, impeller and inclined hole plate by using the impeller, so that the mixed slurry has a greater collision with the inclined hole plate, then passes through the inclined hole plate, and is then accelerated and stirred by the impeller again, so that the mixed slurry changes direction, separates and collides each time it passes through the impeller and the inclined hole plate, thereby achieving mixing, ensuring the mixing effect, and reducing the required length of the mixing tube.
