Description

Technical Field

[0001] This utility model relates to the field of mineral processing technology, and in particular to a high-efficiency flotation device for fine particles. Background Technology

[0002] A high-efficiency flotation device for fine particles is a core piece of equipment used in mineral processing, chemical engineering, and material purification to separate and purify small-sized mineral particles and chemical raw materials. These fine-particle materials have extremely high requirements for bubble contact and particle dispersion during flotation due to their small particle size and large specific surface area. This device is a specialized piece of equipment developed to meet the high-efficiency separation needs of such materials.

[0003] In existing technologies, the flotation of fine-particle materials mostly uses conventional flotation machines. Their main structure includes a flotation tank with an aeration disc at the bottom to generate bubbles, and a single set of stirring devices inside the tank. The technical principle is that the stirring device drives the material to flow within the tank, while the aeration disc continuously releases bubbles. Utilizing the surface adsorption difference between the material particles and the bubbles, the target particles float to the surface with the bubbles, achieving separation.

[0004] However, in the existing technology, fine-grained materials are prone to agglomeration and forming large particle clusters due to their small size and high surface energy. It is difficult to fully disperse them by relying on a single set of agitation. At the same time, the matching degree between the bubbles generated by the aeration disc and the material flow path is low, and the agglomerated particle clusters are difficult to fully contact the bubbles, resulting in a reduction in the material-bubble bonding efficiency and affecting the flotation speed and separation efficiency.

[0005] Regarding the aforementioned technologies, fine-grained materials, due to their small size and tendency to agglomerate, face difficulties in achieving sufficient contact with air bubbles during flotation, resulting in low binding efficiency. Utility Model Content

[0006] The purpose of this application is to provide a high-efficiency flotation device for fine particles, including a flotation tank, an agitation assembly provided on the inner wall of the flotation tank, a feed pipe provided on one side of the outer wall of the flotation tank, a discharge port provided on the other side of the outer wall of the flotation tank, and a quick-release assembly provided between the discharge port and the outer wall of the feed pipe.

[0007] The stirring assembly includes stirring blades disposed on the inner wall of the flotation tank. A stirring motor is fixedly connected to the upper surface of the flotation tank. A transmission rod is fixedly connected to the output end of the stirring motor. A cylinder is disposed on one side of the outer wall of the stirring motor. A beater head is fixedly connected to the output end of the cylinder. A telescopic cylinder is fixedly connected to the upper side of the inner wall of the flotation tank. A telescopic column is slidably connected to the inner wall of the telescopic cylinder. An air pump is disposed on the other side of the outer wall of the stirring motor. An air supply pipe is fixedly connected to the output end of the air pump.

[0008] With the above technical solution, after the fine-grained material enters the flotation tank through the feed pipe, the stirring motor starts to work, which drives the transmission rod and stirring blades to rotate and stir the material. The air pump delivers gas through the air supply pipe to form bubbles in the tank. At the same time, the cylinder drives the beater head to move up and down. During this period, the telescopic column slides in the telescopic cylinder to maintain stable movement and beat the material, thereby promoting the combination of material and bubbles. The material that has completed flotation is finally discharged from the discharge port.

[0009] Preferably, the quick-release assembly includes a fixing rod disposed on the outer wall of the feed pipe.

A moving platform is fixedly connected to one end of the second spring. A first spring is fixedly connected to the inner wall of the pressing rod, and a fixing column is fixedly connected to one end of the first spring.

[0010] With the above technical solution, when performing the connection operation, firstly, flange ring one and flange ring two are fitted together, then the connecting cylinder is inserted into them. Next, the button is pressed to move the extrusion rod. At this time, spring one rebounds, causing the fixing column to fix the extrusion rod, while the extrusion head will squeeze the pressure block, causing the fixing rod to rotate around the pivot and connect and fix with flange ring two. When disassembly is required, press the fixing column to compress spring one, and spring two will push the moving platform, causing the fixing rod to rotate in the opposite direction and disengage from flange ring two.

[0011] Preferably, the outer wall of the fixed column is slidably connected to the inner wall of the connecting cylinder, and the outer wall of the fixed column is slidably connected to the inner wall of the extrusion rod.

[0012] The above technical solution uses the connection between the fixed column and the connecting cylinder to fix the extrusion rod.

[0013] Preferably, the outer wall of the extrusion head is slidably connected to the inner wall of the pressure block, and the upper surface of the fixing rod is attached to the outer wall of the flange ring.

[0014] Through the above technical solution, the pressure head is used to compress the pressure block, and the fixing rod is used to fix flange ring one and flange ring two.

[0020] Through the above technical solution, the telescopic column is used to assist in the movement of the striking head.

[0021] Preferably, one end of the gas supply pipe is fixedly connected to the inner wall of the flotation tank, and two beaters are provided.

[0022] The above technical solution allows the gas pipeline to transport gas into the flotation tank.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. In this utility model, the material enters the flotation tank through the feed pipe. The stirring motor drives the stirring blades to rotate and stir the material. The air pump delivers air to form bubbles. The cylinder drives the beater head to move up and down to beat the material, promoting the full combination of the material and the bubbles.

It achieves the goal of enabling fine-grained materials to combine with bubbles efficiently during the flotation process. In addition, the beating enhances the collision probability between particles and bubbles, ultimately accelerating the flotation speed.

A pivot 24 is fixedly connected to the inner wall of the connecting cylinder 16. A pivot point is provided for the fixed rod 21, allowing it to rotate flexibly. The fixed rod 21 is rotatably connected to the outer wall of the rotating shaft 24. A pressure block 22 is fixedly connected to the outer wall of the fixed rod 21. A second spring 23 is fixedly connected to the lower side of the inner wall of the connecting cylinder 16. One end of the second spring 23 is connected to the moving platform 25, and the other end of the second spring 23 is connected to the inner wall of the connecting cylinder 16.

[0037] Specifically: During connection, attach flange ring 13 and flange ring 24, insert the connecting cylinder 16, press button 15 to move the extrusion rod 17, spring 18 rebounds to fix the extrusion rod 17 with the fixing post 19, and the extrusion head 20 presses the pressure block 22 to make the fixing rod 21 rotate around the rotating shaft 24 and connect and fix it with flange ring 24. During disassembly, press the fixing post 19 to compress spring 18, spring 23 pushes the moving platform 25 to make the fixing rod 21 rotate in the opposite direction and disengage from flange ring 24.

[0038] Figures 1-5The outer wall of the fixed column 19 is slidably connected to the inner wall of the connecting cylinder 16, the outer wall of the fixed column 19 is slidably connected to the inner wall of the extrusion rod 17, the outer wall of the extrusion head 20 is slidably connected to the inner wall of the pressure block 22, the upper surface of the fixed rod 21 is attached to the outer wall of the flange ring 14, the outer wall of the moving table 25 is slidably connected to the inner wall of the connecting cylinder 16, the outer wall of the connecting cylinder 16 is set on the inner wall of the flange ring 14, the outer wall of the fixed rod 21 is rotatably connected to the inner wall of the connecting cylinder 16, the outer wall of the transmission rod 12 is fixedly connected to the inner wall of the stirring blade 13, the outer wall of the transmission rod 12 is rotatably connected to the inner wall of the flotation tank 1, one end of the telescopic column 10 is fixedly connected to the upper surface of the beater head 11, the outer wall of the beater head 11 is set on the inner wall of the flotation tank 1, one end of the gas supply pipe 9 is fixedly connected to the inner wall of the flotation tank 1, and two beaters head 11 are provided.

[0039] Working principle: When a high-efficiency flotation device for fine particles is needed, the fine particles enter the flotation tank 1 through the feed pipe 8. The stirring motor 6 is started, and its output end drives the transmission rod 12 to rotate, which in turn causes the stirring blade 13 to rotate in the flotation tank 1 to stir the material. After the air pump 7 is started, it delivers gas into the flotation tank 1 through the air supply pipe 9, allowing the gas to fully contact the material to form bubbles. At the same time, the cylinder 4 is started, and its output end drives the beater head 11 to move up and down. During the movement, the telescopic column 10 slides in the telescopic cylinder 5 to maintain stability. The beater head 11 beats the material, promoting the combination of the material and the bubbles and improving the flotation effect. The material that has been flotated is discharged through the discharge port 2.

[0040] In addition, when connecting the feed pipe 8 or discharge port 2 to the corresponding component, flange ring 13 and flange ring 24 are fitted together, and then the connecting cylinder 16 is passed through flange ring 13 and flange ring 24. Then, the button 15 is pressed to move the extrusion rod 17. While the extrusion rod 17 is moving, it also moves the fixing column 19 and spring 18. Because spring 18 is initially compressed, when the extrusion rod 17 moves to the appropriate position, spring 18 rebounds and pushes the fixing column 19 through the connecting cylinder 16. At this time, the fixing column 19 fixes the extrusion rod 17. While the extrusion rod 17 is moving, it also drives the extrusion head 20 to extrude the pressure block 22. The pressure block 22 is compressed and drives the fixing rod 21 to rotate. Rotating shaft 24 causes fixed rod 21 to connect with flange ring 14 for fixation. At the same time, pressure block 22 is pressed against moving table 25, which connects feed pipe 8 and discharge port 2 to corresponding components. When discharge port 2 and feed pipe 8 need to be disassembled from corresponding components, first press fixed column 19 to compress spring 18. At this time, spring 23 will push moving table 25 to move. Moving table 25 pushes pressure block 22 to move. At this time, extrusion head 20 no longer presses pressure block 22. As pressure block 22 moves, it drives fixed rod 21 to rotate around rotating shaft 24. At this time, rotating shaft 24 is no longer connected to flange ring 14, thus achieving disassembly.
