[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 A stirring device for reactor production includes a reaction tank 1. The reaction tank 1 is equipped with a stirring mechanism, which includes a first motor 2 mounted on the top of the reaction tank 1. The output end of the first motor 2 is fixed downwards to a main stirring ring 3. A spiral conveyor belt 4 is disposed in the middle of the main stirring ring 3. Three sub-stirring groups are rotatably connected to the main stirring ring 3. Each sub-stirring group includes a driven shaft 5, an auxiliary stirring ring 6, and stirring rods 7. The driven shaft 5 is fixed to the auxiliary stirring ring 6, and multiple stirring rods 7 are fixed to the auxiliary stirring ring 6. The driven shaft 5 is rotatably connected to the main stirring ring 3. A gear 8 is fixed upwards through the main stirring ring 3 at the top of the driven shaft 5. An annular gear rail 9 is fixed on the inner top wall of the reaction tank 1, and the gear 8 meshes with the annular gear rail 9. A feed inlet 10 is provided at the top of the reaction tank 1, and a discharge outlet 11 is provided at the bottom of the reaction tank 1.

[0024] When using this device, the material is poured into the feed inlet 10, and the first motor 2 is started to drive the main stirring ring 3 to rotate, which in turn drives the spiral conveyor belt 4 to rotate, thus transporting the material in the reaction tank 1 from small to large. The main stirring ring 3 also drives the sub-stirring group to achieve a circular motion. Since the top of the driven shaft 5 is fixed with a gear 8, and the inner top wall of the reaction tank 1 is fixed with a ring toothed rail 9, the two mesh. When the driven shaft 5 moves in a circular motion, it achieves the rotation of the driven shaft 5. The driven shaft 5 drives the auxiliary stirring ring 6 and the stirring rod 7 to rotate in the opposite direction to the rotation of the main stirring ring 3, thus achieving full stirring of the material.

[0025] In actual use, it was found that in order to make the stirring mechanism rotate more stably, in this embodiment, a support block 12 is fixed on the inner bottom wall of the reaction tank 1, and the main stirring ring 3 is rotatably connected to the support block 12.

[0026] In actual use, it was found that materials would accumulate at the top of the support block 12 and were difficult to clean. In order to avoid the above problems, in this embodiment, the top of the support block 12 is set as a slope.

[0027] In actual use, it was found that the material tends to accumulate at the bottom of the reaction tank 1, making it difficult to discharge completely. In order to solve the above problem, in this embodiment, the inner bottom wall of the reaction tank 1 is set as a curved surface with a concave center.

[0028] In actual use, it was found that in order to control the discharge rate, a control valve 13 is provided on the discharge port 11 in this embodiment.

[0029] In actual use, it was found that the device is prone to slipping and moving under the action of external force. In order to solve the above problem, in this embodiment, the bottom end of the reaction tank 1 is fixed with a plurality of support legs 14, and the bottom end of the support legs 14 is provided with anti-slip texture.
