Description

Technical Field

[0001] The utility model relates to the technical field of mining production, in particular to a stirring tank mixing overflow device for mining. Background Art

[0002] Agitated tanks are common mixing vessels in mineral processing, used for leaching, reagent-mineral reactions, and other applications. Their most direct function is to evenly mix two or more substances before discharging them. Mining agitated tank mixers are a type of equipment used in mineral processing. In existing technology, a motor-driven V-belt drives the impeller to thoroughly mix the reagent and ore slurry, increasing the reagent's reaction time and thus enhancing the quality of the reaction.

[0003] A stirring tank is a mixing vessel used in the iron ore flotation process. It receives the iron ore slurry (containing ore particles, powder, and water) crushed by the ball mill and the beneficiation reagents. A motor-driven paddle rotates to thoroughly agitate the mixture, and the mixed slurry is discharged through an overflow port to the next process. Existing equipment includes common forms such as cylindrical and conical. However, these systems present the following production challenges: 1. During operation, the dense ore in the slurry tends to settle under gravity and accumulate at the bottom of the stirring tank. This accumulated ore rapidly wears the high-speed rotating paddles, shortening the blade replacement cycle. 2. Excessive accumulation of settled ore creates excessive resistance, leading to motor overload, shortening motor life, or even damaging the motor. 3. The dense slurry sinks, leaving the lower-density mixture in the upper portion, resulting in uneven mixing of the reagents and slurry.

[0004] To address these issues, manufacturers currently rely on stopping the machine to manually clean the bottom of the ore, replacing worn blades, and replacing motors when problems arise. All of these solutions require stopping the machine, significantly impacting overall production line efficiency and incurring high replacement and repair costs.

[0005] Therefore, we designed a mixing overflow device for a mining agitator tank to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a mixing overflow device for a mining stirring tank, so as to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the utility model provides a mixing overflow device for a mining stirring tank, including a main barrel body and a stirring power device. A flow stabilizer is provided inside the main barrel body, and a guide groove is also provided on the inner wall of the main barrel body. A hollow body is provided in the guide groove, and an overflow hole is provided at the connection position between the hollow body and the main barrel body. The lower part of the hollow body is connected to the inner cavity of the main barrel body. The distance between the overflow hole and the top of the main barrel body is L1, and the distance between the bottom of the guide groove and the bottom of the main barrel body is L2.

[0008] Specifically, the distance L2 between the bottom of the guide groove and the bottom of the main barrel is 60-90 cm, preferably 65 cm.

[0009] Specifically, the distance L1 between the overflow hole and the top of the main barrel body is 45-55 cm, preferably 50 cm.

[0010] Specifically, the diameter of the overflow hole is 40-60 cm, preferably 50 cm.

[0011] Specifically, the stirring power device includes a stirring blade, a stirring rod 21 and a stirring motor 23 connected in sequence, and the stirring motor 23 is connected to the stirrer fixing device 22.

[0012] Specifically, the device is used for iron ore flotation.

[0013] Compared with the existing technology, the technical solution of the present invention is adopted to increase the liquid lift by setting a guide groove, so that the ore that is easy to settle can be discharged more conveniently during the slurry overflow process, thereby avoiding the problem of cumulative sedimentation of the ore and accumulation at the bottom of the stirring tank, thereby achieving the purpose of improving productivity and reducing maintenance costs.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Figure 1 This is a schematic diagram of the overall result of the utility model. Figure 2 This is a cross-sectional diagram of the connection between the diversion channel and the main barrel body, see Figure 1-2 The present utility model claims protection for a mixing overflow device of a stirring tank for mining, comprising a main barrel body 10 and a stirring power device, a flow stabilizing plate 11 being provided inside the main barrel body 10, and a guide groove 12 being provided on the inner wall of the main barrel body 10, the guide groove 12 being open at the top and bottom, a hollow body 120 being provided inside the guide groove 12, an overflow hole 13 being provided at the connection position between the hollow body 120 and the main barrel body 10, the lower part of the hollow body 120 being communicated with the inner cavity 100 of the main barrel body 10, the overflow hole 13 being at a distance L1 from the top of the main barrel body 10, and the bottom of the guide groove 12 being at a distance L2 from the bottom of the main barrel body 10.

[0019] Specifically, the distance L2 between the bottom of the guide groove 12 and the bottom of the main barrel 10 is 60-90 cm, preferably 65 cm or 70 cm.

[0020] Specifically, the distance L1 between the overflow hole 13 and the top of the main barrel body 10 is 45-60 cm, preferably 50 cm.

[0021] Specifically, the diameter of the overflow hole 13 is 40-60 cm, preferably 50 cm.

[0022] Specifically, the stirring power device includes a stirring blade 20 , a stirring rod 21 and a stirring motor 23 connected in sequence, and the stirring motor 23 is connected to the stirrer fixing device 22 .

[0023] Specifically, the device is used for iron ore flotation.

[0024] During operation, since the guide groove 12 is open at both ends, and the cross-sectional area of ​​the guide groove 12 is much smaller than the cross-sectional area of ​​the main barrel body 10, a relatively narrow slurry flow space is formed in the hollow body 120 inside the guide groove 12. The slurry in the hollow body 120 is connected to the slurry in the barrel cavity 100 at both ends. When the stirring blade 20 is working, the liquid in the original barrel cavity 100 enters the hollow body 120 of the guide groove 12 from the bottom of the main barrel body 10 to obtain a stronger and more stable lift effect. At this time, the flow direction of the slurry is shown in FIG. Figure 2 As shown by the middle arrow, the slurry finally flows into the next process through the overflow hole 13.

[0025] By adopting the technical solution of the present invention, the liquid lift is enhanced by providing the guide trough 12, so that the ore that is easy to settle can be discharged more conveniently during the slurry overflow process, thereby avoiding the problem of ore accumulation and sedimentation at the bottom of the stirring tank.
