[0002] Ultra-low-grade bauxite refers to ore with a low aluminum content, typically less than 30% or even lower, requiring large-scale processing to obtain sufficient aluminum. Currently, ultra-low-grade bauxite requires flotation processing. Flotation agents added to aeration tanks separate the aluminum from other impurities, allowing the flotation to float. After flotation treatment, the ultra-low-grade bauxite can be processed.

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.
[0023] Example
[0024] like Figures 1 to 5 As shown, the utility model proposes a flotation mineralization equipment for ultra-low-grade bauxite beneficiation, including an aeration tank 1, a second filter 5 fixedly installed in the top opening of the aeration tank 1, which is convenient for filtering the bubbles generated by the aeration of the aeration tank 1 and allowing the bubbles to enter the top of the second filter 5; a second through hole is opened on the front wall of the aeration tank 1, and a second solenoid valve 6 is fixedly installed in the second through hole, which is convenient for discharging the medium in the aeration tank 1; a feed square pipe is connected to the back wall of the aeration tank 1 for guiding the material in the aeration tank 1; the feed square pipe is not shown in the drawing because it is arranged at the back of the aeration tank 1 and is blocked by other structures on the aeration tank 1.
[0025] Furthermore, a defoaming assembly 2 is installed at the top opening of the aeration tank 1 to facilitate the treatment of floating bubbles. The defoaming assembly 2 includes a guide cover 21, a defoamer 22, an exhaust cover 23, a drain pipe 24, an arc cover 25 and a first filter 26. The guide cover 21 is arranged at the top wall of the aeration tank 1, which is conducive to guiding the floating bubbles above the second filter 5. The defoamer 22 is fixedly installed in the opening opened on the side wall of the guide cover 21 to facilitate the elimination of floating bubbles. The exhaust cover 23 is fixedly arranged on the outlet side of the defoamer 22, which is conducive to discharging the gas generated by the elimination of floating bubbles to prevent the guide cover 21 from leaking. The internal pressure increases, which affects the subsequent processing work. The inlet end of the drain pipe 24 is set in the first through hole opened on the bottom wall of the exhaust hood 23, which is convenient for discharging the water generated by defoaming and preventing water accumulation in the exhaust hood 23. The arc cover 25 is fixedly installed on the outer wall of the aeration tank 1, and the top opening of the arc cover 25 is fixedly connected to the bottom opening of the guide cover 21, so that the floating bubbles can enter the arc cover 25 for treatment, and pass through the first filter screen 26 fixedly installed in the bottom wall opening of the arc cover 25, which is convenient for further improving the defoaming effect and is beneficial to sharing the defoaming pressure of the defoamer 22.
[0026] Furthermore, a blowing assembly 3 is installed on the guide cover 21 for blowing bubbles. The blowing assembly 3 includes a motor seat 31, a motor 32, a rotating shaft 33, a fan blade 34, a vertical rod 35, a defoaming stick 36 and a cleaning rod 37. The motor seat 31 is fixedly mounted on the other side wall of the guide cover 21, and the motor 32 is fixedly mounted on the top of the motor seat 31. The motor 32 is supported by the motor seat 31. The rotating shaft 33 is arranged in the guide cover 21. One end of the rotating shaft 33 passes through the first rotating hole opened on the other side wall of the guide cover 21 and is connected to the output end of the motor 32, so that the rotating shaft 33 is driven to rotate by the motor 32. At the same time, a sealed bearing sleeve is arranged in the first rotating hole. It is provided on part of the outer surface of the rotating shaft 33 to facilitate sealing the first rotating hole to prevent affecting the subsequent blowing of the bubbles. The two fan blades 34 are symmetrically sleeved on the outer ring surface of the rotating shaft 33. The fan blades of the two fan blades 34 are arranged in a staggered state to facilitate improving the blowing effect. In conjunction with the guidance of the guide cover 21, the purpose of blowing the bubbles is achieved. In conjunction with the defoamer 22 and the first filter 26, the bubbles attached to the bauxite are eliminated, completing the flotation treatment of the bauxite. An air inlet pipe is installed on the back wall of the guide cover 21. The outlet end of the air inlet pipe is located on one side of the fan blade 34, which is conducive to blowing the bubbles. Due to the obstruction of the guide cover 21, the air inlet pipe is not shown in the accompanying drawings.
[0027] A second rotating hole is provided on the vertical rod 35, in which a bearing is arranged. The bearing sleeve is arranged on a part of the outer ring surface of the rotating shaft 33 to assist the rotation of the rotating shaft 33. The top and bottom ends of the vertical rod 35 are fixedly connected to the inner surface wall of the guide cover 21 and the top wall of the aeration tank 1 respectively, and cooperate with the bearing to improve the stability of the rotating shaft 33 during rotation to prevent the end of the motor 32 of the rotating shaft 33 from shaking and hindering the blowing of the bubbles; multiple defoaming rods 36 are welded to the outer ring surface of the rotating shaft 33, and the multiple defoaming rods 36 are arranged in three groups, and the three groups of defoaming rods 36 are fixedly connected to the inner surface wall of the guide cover 21 and the top wall of the aeration tank 1 respectively. One end is connected to a cleaning rod 37, which is L-shaped. The cleaning surface of the cleaning rod 37 is in close contact with the inner wall of the guide cover 21, the defoaming end of the defoamer 22 and the inner surface wall of the first filter 26, which is conducive to rotation driven by the rotating shaft 33. The cleaning rod 37 is used to clean the inner wall of the guide cover 21, the defoaming end of the defoamer 22 and the inner surface wall of the first filter 26, thereby reducing the adhesion of bauxite on the surfaces of the three and affecting the defoaming work. At the same time, the rotation of the defoaming rod 36 can break the bubbles and further improve the defoaming efficiency.
[0028] Furthermore, a collecting assembly 4 for guiding bauxite is installed on the side wall of the aeration tank 1. The collecting assembly 4 includes a collecting box 41, a third filter 42, a guide plate 43 and a first solenoid valve 44. The collecting box 41 is fixedly mounted on the outer wall of the aeration tank 1, and the third filter 42 is fixedly mounted in the opening at the top of the collecting box 41 and is arranged below the first filter 26. Two guide plates 43 are symmetrically mounted on the top wall of the collecting box 41, and cooperate with the third filter 42 in an inclined state to facilitate the guidance and discharge of bauxite falling on the third filter 42. At the same time, the bauxite guided by the third filter 42 can guide the moisture into the collecting box 41 for collection, which is conducive to recycling and reusing water resources and reducing waste in the use of water resources. A second through hole is opened on the front-facing wall of the collecting box 41, and the first solenoid valve 44 is fixedly mounted in the second through hole, which is conducive to draining the water in the collecting box 41 for use.
