Description

Technical Field

[0001] This utility model relates to the field of mixer technology, and in particular to a mixer with an improved mixing shaft. Background Technology

[0002] In industries such as chemical, food, pharmaceutical, and environmental protection, mixers are widely used as important mixing equipment in processes involving the uniform mixing, reaction, heat transfer, and suspension of liquids, slurries, or powders. The design of the core component of traditional mixers—the mixing shaft and its matching impellers—directly affects the mixing efficiency, energy consumption, and applicability of the equipment. Existing mixing shaft structures still suffer from the following technical defects: First, the traditional single-shaft design, due to its simple structure, results in insufficient material mixing uniformity, especially when dealing with multiphase systems, making it difficult to achieve sufficient dispersion. Second, the flow field pattern formed by conventional mixing shafts is singular, easily generating mixing blind zones at low speeds and inducing eddy currents and phase separation at high speeds. This contradictory operating condition not only leads to low energy utilization but also directly restricts the quality stability and process economy of the mixing process. Utility Model Content

[0003] The purpose of this invention is to provide a mixer with an improved stirring shaft to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mixer with an improved stirring shaft, including a support, a stirring tank fixedly connected to the support, a cover plate fixedly connected to the stirring tank, a protective cover fixedly connected to the cover plate, a drive motor fixedly connected to one outer wall of the protective cover, a double-sided bevel gear fixedly connected to the output end of the drive motor and rotatably connected to the protective cover, a single-sided bevel gear meshing with the outer walls of both sides of the double-sided bevel gear and rotatably connected to the cover plate, an output shaft fixedly connected to the single-sided bevel gear, and a stirring blade fixedly connected to the output shaft.

[0005] As a further technical solution of this utility model, cylinders are fixedly connected to the outer walls on both sides of the protective cover, and movable rods are fixedly connected to the output ends of the cylinders. The movable rods are sleeved on the cover plate, and conical plates are fixedly connected to the movable rods.

[0007] As a further technical solution of this utility model, a flow stabilizing hole is provided on the conical plate, and a reinforcing rib is fixedly connected to the movable rod, and the reinforcing rib is fixedly connected to the conical plate.

[0008] As a further technical solution of this utility model, a fixing plate is fixedly connected to the cover plate, and a positioning plate is fixedly connected to the outer wall of the mixing tank at the position corresponding to the fixing plate. A fixing bolt is sleeved on the fixing plate and the fixing bolt is sleeved on the positioning plate. One end of the fixing bolt is threaded with a nut.

[0009] As a further technical solution of this utility model, a discharge pipe and a feed pipe are fixedly connected to the outer wall of the mixing tank, a connecting flange is fixedly connected to one end of the discharge pipe, and a valve is fixedly connected to the discharge pipe.

[0010] As a further technical solution of this utility model, the bracket is fixedly connected with feet and diagonal bracing rods.

[0011] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: This invention adopts a unique dual-shaft counter-rotating composite stirring system, which generates a strong shear convection effect through the counter-movement of the two stirring shafts, improving the mixing uniformity of materials. At the same time, it integrates a vertical mixing mechanism, which uses a cylinder-driven conical plate to form material flow in the axial direction. With the rectification effect of the flow stabilizing holes of the conical plate, precise control of axial and radial flow is achieved. This invention combines the planar mixing of the two-point counter-flow stirring shaft with the axial mixing of the vertical mixing mechanism to construct a highly efficient three-dimensional composite flow field. It not only completely eliminates the mixing dead angle and phase separation problems common in traditional stirring equipment, but also significantly improves the energy efficiency ratio while ensuring mixing quality, providing a brand-new technical solution for high-requirement mixing processes.
