Description

Technical Field

[0001] This utility model relates to the technical field of calcium sulfate production equipment, and in particular to a twin-shaft agitator. Background Technology

[0002] Stirring is an essential step in the production of calcium sulfate. Whether in laboratory preparation or industrial production, stirring significantly improves the dissolution efficiency and production efficiency of calcium sulfate. Specifically, calcium sulfate needs to be mixed with a solvent, and because this material has a certain viscosity when mixed, common stirrers are often insufficient to achieve the desired result.

[0003] Generally, when dealing with dry powder, wet material, granular and sticky materials, a twin-shaft mixer can be used. This mixer uses two mixing shafts to rotate synchronously in reverse, forming a complex material movement trajectory. The shearing force and convection effect of the mixing blades on the mixing shafts can ensure the mixing effect of the material.

[0004] Most commonly used twin-shaft mixers have two horizontally set mixing shafts that rotate synchronously in reverse. In actual operation, in order to ensure the stability of the equipment, the speed is generally set at a low level, which leads to a relative decrease in mixing efficiency. Utility Model Content

The main shaft 210 and the shaft cylinders 220 both extend to the outside of the cylinder 100. Paired gear sets 400 are respectively installed on both ends of the two main shafts 210.

[0028] In this embodiment, the two shaft cylinders 220 are rotatably disposed outside the two ends of the same main shaft 210, and the two shaft cylinders 220 extend to the opposite ends and the two ends of the main shaft 210 respectively to the outside of the cylinder body 100. The motor 500 drives the gear set 400 to drive the main shaft 210 and the shaft cylinders 220 to rotate in opposite directions.

[0029] In one embodiment, please refer to Figure 3 and Figure 4 The stirring component 300 includes several stirring blades 310 fixedly mounted on the shaft cylinder 220 and several stirring rods 320 fixedly mounted on the main shaft 210.

[0030] In this embodiment, stirring blades 310 are provided on the outside of the shaft cylinder 220, and stirring rods 320 are provided on the part of the main shaft 210 that is not covered. The stirring blades 310 located on the outside of the shaft cylinder 200 in the same group have opposite installation angles, and their axial pushing force on the material during rotation is also opposite.

[0031] In one embodiment, please refer to Figures 1-5 The gear set 400 includes a gear ring 410 fixedly installed on the end side of the shaft cylinder 220 and a main gear 420 fixedly installed on the end side of the main shaft 210.

[0035] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail as follows: When in use, the motor 500 is started, and the motor 500 drives the main shaft 210 to rotate. The rotation of the main shaft 210 drives the main gears 420 on both ends to rotate. The two main gears 420 mesh to drive the driven gear 430. Through the meshing of the driven gear 430, the shaft cylinder 220 is driven to rotate. At this time, the stirring blade 310 and the stirring rod 320 rotate in opposite directions to stir the material, so that the material receives shearing forces in different directions, thereby improving the stirring efficiency of the material.

[0036] In summary, this utility model solves the technical problem of relatively low mixing efficiency caused by reducing the rotation speed to ensure the stability of equipment operation in the prior art by using the coaxial but non-directional rotation of the stirring component 300 to stir the material.
