Description

Mixing mechanism for concentrated mixing tank Technical Field The utility model belongs to the technical field of thick mixing tanks, and particularly relates to a mixing mechanism for a thick mixing tank. Background In the operation of a concentrated tank in the fields of pharmacy, chemical industry and the like, the full mixing of materials is a key process link for ensuring the uniformity of products. The vertical puddler that traditional compounding mechanism generally adopted to arrange along jar body axis direction is as core compounding subassembly, realizes through the rotary motion of stirring rake on the horizontal plane that the material mixes. However, the structure has the remarkable limitation in practical application that when multiphase materials with large density difference are processed, components with different densities can generate layering phenomenon in the vertical direction under the action of gravity, and particularly, the interface can continuously exist in a specific height interval of the tank body. Because the traditional stirring rod can only stir in a two-dimensional plane in the circumferential direction, the material layered structure in the vertical direction cannot be effectively broken, and the mixing efficiency is greatly reduced. In order to solve the above problems, a compensation method for prolonging the stirring time or increasing the stirring rotation speed is generally adopted in the prior art. However, the energy consumption is obviously increased (the experimental data show that the energy consumption can be increased by more than 40 percent), and the risk of denaturation of the heat-sensitive material caused by excessive shearing is further increased. Some improvement schemes attempt to install oblique blades on the stirring rod, but the three-dimensional mixing effect cannot be realized due to the fact that the installation angle of the blades is fixed and an axial movement component is lacked. In addition, the single stirring shaft structure is easy to form a mixing blind area in the central area of the tank body, and particularly when the viscosity of the materials is high, the phenomenon of insufficient mixing in the central area is more remarkable. Therefore, development of a novel mixing mechanism capable of realizing three-dimensional mixing and effectively eliminating vertical layering of materials is needed.
