Description

Technical Field

[0001] The utility model relates to the technical field of stirring tanks, in particular to an anti-precipitation high-efficiency stirring tank, in particular to stirring before selection in a mineral processing process and stirring in a reagent dissolving process. Background Art

[0002] Mixing tanks are often used for mixing liquids, bulk solids or a variety of slurry materials. In actual industrial production, when ordinary mixing tanks process materials of different properties, they will encounter problems such as insufficient mixing and fusion of materials, easy precipitation of high specific gravity materials, and rapid wear of mixing blades and tank bodies caused by high hardness materials.

[0003] In the actual operation of the process, due to the large amount of slurry in the upstream process, it also contains solid particles with extremely high hardness and specific gravity. In the actual production process, ordinary mixing tanks have always had many problems such as poor mixing effect caused by excessive amount, insufficient mixing after the additives enter the mixing tank, and inconvenient fine operation. In order to solve the problem of poor mixing effect, the depth of the mixing shaft, the diameter of the impeller, and the volume of the tank have not been completely solved. First, due to the high specific gravity of the material, extending the depth of the mixing shaft will cause the upper load of the impeller to increase seriously, which may easily cause the impeller to be "crushed to death"; secondly, increasing the diameter of the impeller will cause the high-hardness material particles to wash the side wall of the mixing tank due to the huge centrifugal force, and at the same time, it will cause the load of the mixer to increase seriously, causing the motor to burn out; in addition, after increasing the volume of the tank, due to its own specific gravity, the material far from the center will settle around the lower part of the side wall of the tank, and the purpose of expanding the effective volume of the mixing tank cannot be achieved. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-sedimentation high-efficiency stirring tank, which can effectively avoid various drawbacks such as excessive wear, poor stirring effect, large stirring load, and rapid material sedimentation, thereby solving the problems raised in the above background technology.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A sedimentation-proof and efficient stirring tank comprises a cylindrical tank body 1, wherein a guide tube 2 is arranged on the lower side of the interior of the cylindrical tank body 1 through a fixed bracket 3, guide ports are opened at the upper and lower ends of the guide tube 2, a stirring impeller is arranged in the guide tube 2, the stirring impeller is arranged on a stirring shaft 4, the upper end of the stirring shaft 4 is connected to a driving assembly 11 installed on the top of the cylindrical tank body 1, a discharge port 5 is arranged at the bottom of the cylindrical tank body 1, a feed pipe 6 and a discharge pipe 7 are arranged on the upper side wall of the cylindrical tank body 1, the feed pipe 6 is installed obliquely, and the outlet of the feed pipe 6 is located directly above the top opening of the guide tube 2.

[0007] The stirring shaft 4 is composed of an upper shaft and a lower shaft, which are connected together by a flange coupling. The upper shaft is connected to the driving assembly 11, and a stirring impeller is arranged on the lower shaft and inserted into the guide tube 2.

[0008] The stirring impeller comprises a flat-paddle upper impeller 8 and a propulsion lower impeller 9 . The flat-paddle upper impeller 8 is arranged at the upper part of the guide tube 2 , and the propulsion lower impeller 9 is arranged at the lower part of the guide tube 2 .

[0009] The guide tube 2 has two lower guide ports, which are symmetrically arranged on both sides of the bottom of the guide tube 2 in an eight-shaped shape.

[0010] A mounting bracket 10 is disposed on the top of the cylindrical tank body 1 , and the driving assembly 11 is mounted on the mounting bracket 10 .

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] 1. The utility model sets the upper shaft and the lower shaft through the flange coupling. On the one hand, the lower shaft can be further extended so that it can be inserted deeper into the bottom of the liquid surface, and the bottom stirring effect will be better; on the other hand, the two parts can be repaired separately according to their respective life cycles, saving costs, facilitating replacement and maintenance, and the upper lifting space does not need to be too high. In addition, when replacing the bearing, there is no need to cut and remove the impeller, and when replacing the impeller, there is no need to cut and remove the bearing. While shortening the maintenance time, unnecessary waste is greatly reduced;

[0013] 2. The utility model can effectively stir the upper slurry by setting a flat-paddle upper impeller to ensure sufficient stirring of the material and prevent sedimentation;

[0014] 3. The guide tube provided in the utility model can effectively sort out the circulation stability and regularity of the slurry inside the tank body, and reduce the turbulent disturbance inside the tank body. Through the combing effect of the impeller combination of different types in the upper and lower parts and the guide tube structure on the flow direction of the slurry, a circulating vortex will be formed inside the tank body during actual operation, which greatly improves the overall working efficiency of the mixing tank.
