[0003] In order to address the above problems, the existing Chinese patent with announcement number CN218530934U proposes a reactor that is easy to clean the inner wall. The device drives the rotating shaft to rotate through a motor, and the rotating shaft drives the stirring rod to rotate, so that the scraper and brush connected to the stirring rod also rotate accordingly. One end of the scraper and the brush are close to the inner wall of the reactor body to achieve the effect of cleaning the inner wall.

[0004] However, although the above-mentioned reactor that is easy to clean the inner wall can drive the stirring roller to rotate through the rotating shaft, so that the scraper and the brush follow the rotation and clean the inner wall of the reactor body, the reactor that is easy to clean the inner wall has a groove that is always connected to the stirring rod. When the stirring rod stirs the material, the groove will rotate together with the stirring rod, thereby affecting the stirring of the material and reducing the stirring efficiency of the material. Therefore, the utility model provides a reactor that is easy to clean the inner wall to meet the demand. Utility Model Content

[0040] Specifically, when it is necessary to clean the inner wall of the kettle body 1, the limiting groove 15 is limited by the clamping assembly 5, so that the stirring shaft 7 and the ring 13 are fixedly connected, so that when the motor 6 drives the stirring shaft 7 to rotate, the cleaning mechanism 9 can clean the inner wall of the kettle body 1. Similarly, when it is not necessary to clean the inner wall of the kettle body 1, it is only necessary to release the limiting groove 15 by the clamping assembly 5. The overall operation is simple, and the operation of the cleaning mechanism 9 can be adjusted according to actual needs to avoid the influence of the cleaning mechanism 9 when the material is stirred, thereby improving the stirring efficiency of the material, and solving the problem that the existing reactor has the clamping groove connected to the stirring rod all the time, which makes the stirring rod rotate with the clamping groove when stirring the material, thereby affecting the stirring of the material and reducing the stirring efficiency of the material.

[0041] It should be noted that the clamping assembly 5 is installed on the stirring shaft 7, and the clamping assembly 5 will not loosen when the stirring shaft 7 rotates, so that the clamping assembly 5 can continuously limit the limiting groove 15, wherein the clamping assembly 5 is a mechanism that can fix the ring 13 to the stirring shaft 7; in this embodiment, the motor 6 can be a three-phase motor 6, a reduction motor 6, etc.

Specifically The pushing mechanism 51 pushes the wedge block 1 52 toward the wedge block 2 53, so that the wedge block 1 52 pushes the wedge block 2 53 toward the limiting groove 15, thereby driving the limiting rod 56 to limit the limiting groove 15 under the action of the connecting rod 55. At this time, the wedge block 2 53 squeezes the spring 54. When the pushing mechanism 51 pulls the wedge block 1 52 away from the wedge block 2 53, the wedge block 2 53 is reset under the action of the spring 54, so that the limiting rod 56 no longer limits the limiting groove 15. The overall operation is simple, which is convenient for realizing the rapid limitation of the limiting groove 15, thereby improving the efficiency of cleaning the inner wall of the kettle body 1.
