[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating the basic structure of the present invention only in a schematic manner, and therefore only show components relevant to the present invention. In the description of the present invention, it should be understood that, unless otherwise specified, "a plurality" means two or more.

[0030] See also Figure 1The specific embodiment of the present invention is a lifting stirring assembly 4, which includes a motor 1, a reducer 2, a frame 3, a stirring assembly 4 and a lifting assembly 5. The reducer 2 is installed on the frame 3 and is connected to the output shaft of the motor 1. The stirring assembly 4 is connected to the output shaft of the reducer 2 so as to be able to drive the stirring assembly 4 to rotate in both directions. The lifting assembly 5 is connected to the stirring assembly 4. When the stirring assembly 4 rotates in both directions, the lifting assembly 5 can drive the stirring assembly 4 to move synchronously along its axial direction. Compared with the traditional stirring assembly 4, the lifting stirring assembly 4 can not only realize unidirectional rotation, but also realize bidirectional rotation. At the same time, during the rotation process, the stirring assembly 4 can be driven by the lifting assembly 5 to move along the axial direction of the stirring assembly 4, so as to adjust the stirring position of the stirring assembly 4, thereby ensuring the mixing effect while better meeting special and complex working conditions and meeting actual use requirements.

[0031] See also Figure 2 Specifically, the stirring assembly 4 includes a stirring shaft 41 and a stirring blade 42, wherein the stirring blade 42 is arranged on the stirring shaft 41 so as to be able to drive the stirring blade 42 to rotate synchronously when the stirring shaft 41 rotates. The reducer 2 is a hollow shaft reducer 2, and the stirring shaft 41 is arranged in the hollow shaft reducer 2 and can move along the axial direction of the hollow shaft reducer 2, and during the axial movement, the stirring shaft 41 can rotate synchronously. The stirring shaft 41 and the hollow shaft reducer 2 are connected by a flat key or a spline to effectively transmit power and torque. In addition, the lifting assembly 5 includes a driving mechanism 51 and a lifting beam 52 arranged in pairs, and the driving mechanism 51 includes an electric cylinder or a hydraulic cylinder. The lifting beam 52 is connected to one end of the stirring shaft 41, and can drive the lifting beam 52 to move synchronously when the electric cylinder or the hydraulic cylinder is working. Because the electric or hydraulic cylinders are arranged in pairs, each is equipped with limit switches at its upper and lower ends. These limit switches control the maximum travel of the lifting assembly 5, i.e., the upper and lower limits of the electric or hydraulic cylinder, and simultaneously provide interlocking protection in conjunction with electrical control. Furthermore, the paired arrangement of the electric or hydraulic cylinders ensures coordinated and consistent ascent and descent. When the lifting assembly 5 reaches its highest position, the reducer 2, frame 3, and mechanical seal 6 remain in their original positions and do not rise synchronously with the lifting assembly 5.

[0032] See also Figure 3The end of the stirring shaft 41 away from the stirring blade 42 is provided with a stepped surface, which is connected to the lifting assembly 5 via a roller bearing assembly. A double round nut 535 is also provided at the connection between the lifting assembly 5 and the stirring shaft 41. The double round nut 535 can lock the stirring shaft 41 and the lifting assembly 5. The use of the double round nut 535 for locking can effectively prevent the threads at this location from loosening, effectively avoiding the possibility of loosening at this location, thereby locking the stirring shaft 41 and the lifting assembly 5, and also realizing bidirectional rotation of the stirring shaft 41. The bidirectional rotation of the stirring shaft 41 includes forward and reverse rotation, which can be performed forward or reverse according to actual requirements, or can be operated alternately.

[0033] See also Figure 3 Specifically, the roller bearing assembly includes a first roller bearing 531 and a second roller bearing 532. The first roller bearing 531 abuts against the step section of the step surface away from the stirring blade 42. The end face of the first roller bearing 531 also abuts against the stop washer. The second roller bearing 532 abuts against the step section of the step surface close to the stirring blade 42. In addition, a pressure cap 533 is provided at the end of the second roller bearing 532 close to the stirring blade 42. The packing seal inside the pressure cap 533 is used to limit the grease in the second roller bearing 532 or the first roller bearing 531 from dripping along the axial direction of the stirring shaft 41. A dust cover 534 is also provided at the end of the first roller bearing 531 away from the stirring blade 42. The dust cover 534 can prevent external dirt from entering the first roller bearing 531 or the second roller bearing 532 and affecting the normal operation of the roller bearing assembly.

[0034] In order to ensure the airtightness of the structure during the mixing process, a mechanical seal 6 is provided at the shaft seal between the output shaft of the reducer 2 and the stirring shaft 41. The mechanical seal 6 is different from the conventional mechanical seal structure (the conventional mechanical seal structure requires the mechanical seal ring to be tightly fixed on the stirring shaft 41, and the rotation of the stirring shaft 41 is suitable for driving the mechanical seal ring to operate, while its axial back and forth movement can hardly achieve airtightness within the structure). The mechanical seal 6 used in this embodiment can not only ensure the airtightness of the lifting component 5 in a static state, but also ensure the airtightness of the lifting component 5 during movement. In addition, the airtightness inside the tank body is ensured during the entire operation process, so that the material inside the tank body can work continuously under a certain pressure. However, during the lifting process of the conventional stirring component 4, the tank body needs to be in a normal pressure state, so it cannot ensure that the material inside the tank body can work continuously under a certain pressure. At the same time, in conjunction with the lifting component 5, the stirring component 4 can stop at any position to stir and mix, and is particularly suitable for working conditions where stratification is more serious.
