Description

Technical Field

[0001] This utility model relates to the field of flotation technology, and in particular to a flotation stirring device for muddy ore. Background Technology

[0002] Mud-forming minerals refer to minerals in which, during mineral processing, due to physical crushing, chemical weathering, or other factors, originally larger ore particles are broken down into very fine particles (usually less than a few micrometers to tens of micrometers in diameter). These fine particles exhibit properties similar to mud, posing unique challenges to subsequent mineral processing. Mud-forming mineral flotation agitation equipment is a machine used in mineral processing. Its main function is to disperse the slurry and distribute air or other gases evenly in the slurry through agitation during the flotation process, thereby promoting the separation of target minerals from gangue (useless minerals). During the flotation process, by adding specific chemical reagents, the target minerals can adhere to air bubbles and float to the surface of the slurry to form a foam layer, which is then scraped and collected.

[0003] Chinese Patent Publication No. CN216910618U discloses a flotation device for non-ferrous metal mines, including a sorting tank. An air inlet pipe is vertically installed inside the sorting tank. Horizontal air supply pipes are installed on the front and rear sides of the bottom of the air inlet pipe, and the two air supply pipes are connected by a connecting pipe. The middle of the connecting pipe is connected to the bottom of the air inlet pipe. A gap is left between both air supply pipes and the bottom of the sorting tank. Several air outlets are provided on the air supply pipes. Stirring components for stirring the slurry in the sorting tank are installed on both the left and right sides of the air inlet pipe. This invention discharges air from multiple directions into the tank through the air supply pipes. While the impeller stirs the slurry, it breaks large air bubbles into numerous small bubbles, which are then evenly distributed in the slurry to form mineralized bubbles with the mineral particles. These bubbles eventually accumulate at the top of the slurry, allowing the mineral particles in the slurry to be fully floated out, reducing workload and improving efficiency.

[0004] The existing technical solutions described above have the following shortcomings: During the use of this flotation equipment, the goal is to obtain minerals from the flotation foam. The basic principle of flotation is to utilize the different surface properties of minerals and add reagents such as collectors to selectively attach the target minerals to the bubbles. As the bubbles rise to the surface of the slurry, they form a foam layer. These bubbles are then scraped off to collect the enriched target minerals. However, when the slurry contains a large number of fine particles, these fine particles will increase the overall solid content of the slurry, thereby increasing the viscosity of the slurry. This has an adverse effect on the agitated flotation process. In order to improve this situation, it is necessary to design a muddy mineral flotation agitation equipment to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a flotation mixing device for muddy minerals, in order to solve the problem mentioned in the background art that when the slurry contains a large number of fine particles, these fine particles will increase the overall solid content of the slurry, thereby increasing the viscosity of the slurry, which has an adverse effect on the mixing and flotation process.

Due to the similarity in height between the rotating rod and the filter screen, and the elasticity of the spring frame, the filter screen vibrates, preventing the slurry from clogging it. The slurry intercepted by the filter screen is then used for flotation. Extremely fine particles pass through the filter screen and plate and fall to the bottom of the flotation mixing tank. Under the meshing action of the gears, the jet pipe rotates, and in conjunction with the activated flow guide chamber, air is blown into the interior of the flotation mixing tank from multiple angles, further improving the mixing effect between the capture agent and the target mineral. By screening out fine particles in advance, the overall solid content in the reaction slurry is reduced to a certain extent, which helps to lower the viscosity of the slurry and avoids adverse effects on the flotation process.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Combination Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The filter frame 21 has an internal elastic frame 211, and the elastic frame 211 has an internal filter screen 212. The side view of the guide cavity 6 has a concave shape. A motor B7 is located on one side of the flotation mixing tank 1, and a rotating rod 71 is located on the output shaft of the motor B7. A striking plate 72 is fixed on the lower surface of the rotating rod 71. The height of the rotating rod 71 to the filter screen 212 is the same as the height of the striking plate 72. The rotating rod 71 and the striking plate 72 are located between the filter frame 21 and the filter plate 22. The side of the jet pipe 62 near the guide cavity 6 is rotatably connected to the inside of the flotation mixing tank 1. A mounting frame 8 is located on the side of the flotation mixing tank 1 away from the guide cavity 6, and a gear 81 is rotatably connected inside the mounting frame 8.

The connecting rod 82 passes through the inner wall of the flotation mixing tank 1 and is rotatably connected to the inner wall of the flotation mixing tank 1. The side of rod 82 furthest from gear 81 is fixedly connected to jet pipe 62 and rotating rod 71 respectively. The auxiliary material box 12 has a through hole A121 inside, and the baffle 52 has six sets of through holes B521 inside. The upper surface of baffle 52 is in contact with the lower surface of auxiliary material box 12. The six sets of through holes B521 are arranged in a circular array inside baffle 52. The cross-sectional size of the six sets of through holes B521 is larger than the cross-sectional size of through hole A121. The lower surface of rotating plate 51 is provided with... The scraper 511 has its lower surface in contact with the inner wall of the auxiliary material box 12. The inner wall of the flotation mixing tank 1 is provided with four sets of mounting plates 14, and each set of four sets of mounting plates 14 has two plates. A stirring fan blade 141 is rotatably connected between each pair of mounting plates 14. An electric telescopic rod A15 is provided on one side of the flotation mixing tank 1, and a push plate 151 is fixed at the telescopic end of the electric telescopic rod A15. The push plate 151 and the discharge port 13 are at the same horizontal height.

[0030] In this embodiment, when the flotation mixing tank 1 needs to be used, the slurry is transported into the interior of the flotation mixing tank 1 through the feed pipe 4, and the scavenging agent is added into the interior of the auxiliary material tank 12 through the feed port 11. By starting the motor A5 and the electric telescopic rod B53, the cross stirring rod 54 and the stirring seat 55 are driven to rotate up and down to achieve stirring of the slurry. Under the downward rotation of the cross stirring rod 54, it will come into contact with the four sets of stirring blades 141, driving the four sets of stirring blades 141 to rotate, further increasing the stirring range and improving the mixing effect of the scavenging agent and the target mineral. At the same time, under the rotation of the baffle 52, the scavenging agent inside the auxiliary material tank 12 is sprayed through the through holes A121 and B521, so that the scavenging agent and the target mineral selectively adhere to the bubbles. As the bubbles rise to the surface of the slurry, a foam layer is formed. By starting the guide cavity 6 and the motor B7, the slurry is stirred. Motor B7 drives the rotating rod 71 to rotate, which in turn drives the striking plate 72 to rotate. Due to the height difference between the rotating rod 71 and the filter screen 212, and the height difference between the striking plate 72 and the filter screen 212, the filter screen 212 vibrates due to the elasticity of the elastic frame 211, preventing the slurry from clogging the filter screen 212. The slurry intercepted by the filter screen 212 is then used for flotation. Very fine particles pass through the filter screen 212 and the filter plate 22 and fall to the bottom of the flotation mixing tank 1. Under the meshing action of the gear 81, the jet pipe 62 rotates. In conjunction with the activated guide cavity 6, air is blown into the interior of the flotation mixing tank 1 from multiple angles, further improving the mixing effect of the capture agent and the target mineral. By screening out the fine particles in advance, the overall solid content in the reaction slurry is reduced to a certain extent, which is beneficial to reducing the viscosity of the slurry and avoiding adverse effects on the flotation process.
