[0033] The output end of the drive motor 5 is fixedly connected with a spline sleeve 6, and the top end of the stirring rod 7 is provided with a spline shaft 8 adapted to the spline sleeve 6.

[0034] Raw materials are fed into the reactor 1 through the feed pipe on the lid 4. Then, the drive motor 5 and heating coil 3 are started by the switch 13. By adding 45° inclined blades 9 to the stirring rod 7, and the inclination direction of adjacent inclined blades 9 is opposite, a three-dimensional shear flow is formed with the original horizontal blades 10. Combined with the bottom arc scraper 11, the problem of material deposition is completely eliminated, the dead angle of stirring is reduced, the material stirring effect is better, the stirring is more uniform, and it is highly practical and worth promoting. In particular, by setting a spline sleeve 6 at the output end of the drive motor 5 and a spline shaft 8 that works with the spline sleeve 6 at one end of the stirring rod 7, a quick-disassembly design is achieved. The stirring components can be disassembled without tools, which is convenient for cleaning and maintenance.

[0035] In this embodiment, the number of inclined blades 9 is multiple sets, which are distributed at intervals along the axial direction of the stirring rod 7, and the inclination angle of each set of inclined blades 9 is 45°±5°.

[0036] Specifically, the width ratio of the horizontal blade 10 to the oblique blade 9 is 1:1.2-1.5, and the surface of the oblique blade 9 is provided with a wave-shaped guide groove with a depth of 3-5mm, which can guide the raw material.

[0037] In this embodiment: the arc of the arc-shaped scraper 11 is consistent with the curvature of the inner bottom wall of the reactor 1, and its edge is covered with a wear-resistant layer.

[0038] Specifically, the wear-resistant layer is made of, but is not limited to, polytetrafluoroethylene, and has a thickness of 2-3mm, which serves to resist wear and extend service life.

Only its use is described, without modification, so the control method and circuit connection are not described in detail.

[0051] Working principle: when in use, the raw materials are put into the reaction kettle 1 through the feed pipe on the kettle cover 4, and then the driving motor 5 and the heating coil 3 are started by the switch 13. By adding 45° inclined paddles 9 on the stirring rod 7, and the inclined directions of adjacent inclined paddles 9 are opposite, a three-dimensional shearing flow is formed with the original horizontal paddle 10, and the bottom arc-shaped scraper 11 is used to completely eliminate the material deposition problem, reduce the stirring dead angle, and improve the material stirring effect and the stirring uniformity. The utility model has strong practicability and is worth promoting.
