Description

Technical Field

[0001] This utility model belongs to the field of mineral processing equipment, specifically relating to a high-efficiency stirring tank for bauxite flotation. Background Technology

[0002] In the flotation process of mineral processing, the mixing tank regulates the rapid and uniform mixing of the slurry and reagents, providing favorable conditions for flotation; it is an indispensable slurry mixing device in the flotation process. In the flotation of coarse-grained sulfide ores, due to the coarse particle size of the flotation feed, the mixing tank is prone to problems such as settling of the mixing tank, excessive wear of the impeller and circulation tank, strong tangential rotational flow of the slurry in the tank, and uneven mixing of slurry and reagents, which seriously restrict the control of flotation process parameters and the stable and smooth operation of production.

[0003] Existing technology CN209752710U discloses a slurry mixing tank, belonging to the field of mineral processing equipment. Addressing the problems of short service life and uneven mixing of slurry and reagents in existing slurry mixing tanks, this invention provides a slurry mixing tank. It includes a tank body with a feed pipe on one side and an overflow port on the other. A crossbeam is mounted on the top of the tank body, and a motor is mounted above the crossbeam, connected to a pulley. It also includes a circulation cylinder housed within the tank body, with its bottom connected to the tank body. A main shaft is installed inside the circulation cylinder, with one end inside the cylinder and the other end passing through a bearing seat on the crossbeam and connected to the pulley. This invention uses a motor to drive the pulley, which in turn drives the main shaft, ensuring thorough mixing of the slurry and reagents within the circulation cylinder. The mixed slurry is discharged from the bottom of the circulation cylinder into the tank body, where it forms an upward flow and exits through the overflow port. Overall, the slurry and reagents are thoroughly mixed, resulting in a long service life.

[0004] While the above method effectively mixes the slurry and reagents thoroughly, it can be further improved to achieve more thorough and efficient mixing. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a high-efficiency mixing tank for bauxite flotation, which enables the slurry and reagents to be fully mixed, resulting in more thorough and efficient mixing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency mixing tank for bauxite flotation, comprising a tank body, an inlet on the lower part of one side of the tank body, an outlet on the upper part of the other side, a crossbeam at the top of the tank body, a motor above the crossbeam, the motor being connected to a pulley, a mixing drum inside the tank body, the top and bottom of the mixing drum being connected to the tank body, a drive shaft inside the mixing drum, one end of the drive shaft being located inside the mixing drum and connected to the mixing impeller, and the other end passing through the crossbeam and connected to the pulley, a feed pipe passing through the upper part of the side of the tank body with the inlet, and the outlet end of the feed pipe being located above the top of the mixing drum.

[0007] Preferably, the bottom of the mixing tank is connected to a branch pipe by bolts. The branch pipe has two symmetrical channel openings, which are inclined outward from the center and gradually decrease in diameter away from the bottom of the mixing tank.

[0008] Preferably, the opening edge at the top of the mixing tank has a rounded corner transition.

[0009] Preferably, the feed pipe is arranged at an angle downwards.

[0010] Preferably, a bearing housing is fixedly connected to the crossbeam, and bearings are provided at both ends of the bearing housing. The drive shaft passes through the bearings and the bearing housing and is connected to the pulley and the stirring impeller respectively.

[0011] Preferably, the blades of the stirring impeller are made of alloy steel and the blade surface is coated with polyurethane.

[0012] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model adopts a mixing tank with both the top and bottom connected to the tank body. The material is fed from the top and bottom of the mixing tank at the same time. The drive shaft rotates inside the mixing tank, and the slurry in the tank is discharged from the top and bottom of the mixing tank into the tank body. The slurry in the tank body forms an upward flow and is finally discharged from the outlet. This can effectively improve the mixing efficiency. The top feeding can quickly disperse light or easily floating materials and prevent them from accumulating on the liquid surface. The bottom feeding directly impacts the core mixing area and promotes the dispersion of heavy or settling materials. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0018] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0019] Example 1

[0020] like Figures 1 to 2 As shown, this utility model provides a high-efficiency mixing tank for bauxite flotation, including a tank body 1. The tank body 1 has a feed inlet 2 at the lower part of one side and a discharge outlet 3 at the upper part of the other side. A crossbeam 4 is set at the top of the tank body, and a motor 5 is set above the crossbeam 4. The motor 5 is connected to a pulley 6. A mixing tank 7 is set inside the tank body 1. The top and bottom of the mixing tank 7 are connected to the tank body 1. A drive shaft 8 is set inside the mixing tank 7. One end of the drive shaft 8 is set inside the mixing tank 7 and connected to the mixing impeller 9. The other end passes through the crossbeam 4 and is connected to the pulley 6. A feed pipe 10 is installed at the upper part of the side of the tank body 1 where the feed inlet 2 is located. The discharge end of the feed pipe 10 is set above the top of the mixing tank 7.

[0021] The mixing tank is connected to the tank body at both the top and bottom. The material is fed from the top and bottom of the mixing tank at the same time. The drive shaft rotates inside the mixing tank, and the slurry inside the mixing tank is discharged from the top and bottom of the mixing tank into the tank body. The slurry in the tank body forms an upward flow and is finally discharged from the outlet. This can effectively improve the mixing efficiency. The top feeding can quickly disperse light or easily floating materials and prevent them from accumulating on the liquid surface; the bottom feeding directly impacts the core mixing area and promotes the dispersion of heavy or settling materials.

[0022] Furthermore, the bottom of the mixing tank 7 is bolted to a branch pipe 11, which has two symmetrical channel openings 1101. The channel openings 1101 slope outwards from the center, and their diameter gradually decreases away from the bottom of the mixing tank 7. The slurry inside the mixing tank 7 flows rapidly under the action of the impeller. The gradually decreasing diameter of the channel openings 1101 ensures thorough mixing of the slurry and reagents within the mixing tank 7.

[0023] Furthermore, the top opening edge of the mixing tank 7 is rounded. The rounded corners increase the size of the top opening, facilitating the flow of slurry from the top and reducing wear on the mixing tank 7.

[0024] Furthermore, the feed pipe 10 is arranged at an angle downwards to facilitate rapid material feeding.

[0025] Furthermore, a bearing seat 12 is fixedly connected to the crossbeam 4, and bearings 13 are provided at both ends of the bearing seat 12. The drive shaft 8 passes through the bearings 13 and the bearing seat 12 and is connected to the pulley 6 and the stirring impeller 9, respectively. The bearings 13 and the bearing seat 12 ensure the stable rotation of the drive shaft 8.

[0026] Furthermore, the blades of the stirring impeller 9 are made of alloy steel, and the blade surface is coated with polyurethane. This improves the corrosion resistance of the blades and extends their service life.

[0027] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
