[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0023] Reference Figure 1-4 As shown,

[0024] A height-adjustable stirring structure comprises a driving component 1, a stirring shaft 2 connected to the driving component 1, and an agitator 3 mounted on the stirring shaft 2. The stirring shaft 2 comprises a connecting shaft 21 for connecting to the driving component 1, and an adjusting shaft 22 coaxially connected to the connecting shaft 21 and axially movable. The agitator 3 is mounted on the adjusting shaft 22, and the adjusting shaft 22 is circumferentially fixed to the connecting shaft 21. An adjusting nut 23 is provided on the adjusting shaft 22, and the adjusting nut 23 is coaxially threadedly connected to the adjusting shaft 22. The adjusting nut 23 is used to limit the movement of the adjusting shaft 22 or release the restriction on the movement of the adjusting shaft 22, so as to limit the movement of the adjusting shaft 22 after adjusting the position of the agitator 3.

[0025] In this solution, the connecting shaft 21 is used to cooperate with the driving component 1 to produce a rotation effect. It can be directly cooperated with the driving component 1 to produce a driving effect, or the driving component 1 can indirectly drive the connecting shaft 21 to rotate through other rotating shafts. The adjusting shaft 22 can be axially movable in cooperation with the connecting shaft 21. After the position of the connecting shaft 21 is fixed, the axial movement of the connecting shaft 21 can be used to adjust the position of the agitator 3. After the adjustment is completed, the adjusting nut 23 is used to lock it, thereby limiting the axial movement of the adjusting nut 23, so that the axial direction is in a fixed state, and the position of the agitator 3 after adjustment is maintained stable. After the adjusting nut 23 is loosened, the adjusting shaft 22 can produce an axial movement effect, thereby adjusting the position of the agitator 3. This adjustment method can set the adjustment position at a position that is as convenient as possible, such as a position close to the driving component 1. Generally, the driving component 1 is located outside the tank body, so the adjustment does not need to enter the tank body, and the position adjustment of this solution is actually the adjusting shaft 22 instead of the agitator 3, so even if the agitator 3 and the adjusting shaft 22 are welded, the position adjustment effect can be produced.

[0026] Preferably, the adjusting shaft 22 is plugged into the connecting shaft 21 , and when the adjusting shaft 22 moves axially, it is inserted into or extended out of the corresponding connecting shaft 21 to adjust the position of the agitator 3 .

[0027] The plug-in method can allow the connecting shaft 21 to provide a guide, which is more convenient when moving the adjustment shaft 22. The connection is also more convenient.

[0028] Of course, in order to facilitate the movement and rotation transmission between the adjustment shaft 22 and the connecting shaft 21, the following two methods can be used for implementation:

[0029] 1. A key is provided on the adjusting shaft 22, and a groove is provided on the connecting shaft 21. The adjusting shaft 22 and the connecting shaft 21 are matched through the key groove to form a circumferential fixation and an axial movable state.

[0030] 2. A groove is provided on the adjusting shaft 22, and a key is provided on the connecting shaft 21. The adjusting shaft 22 and the connecting shaft 21 are matched through the key groove to form circumferential fixation and axial mobility.

[0031] Both of the above-mentioned solutions can produce axial movable action and circumferential fixed action by means of keyway cooperation, and utilize keyway cooperation to transmit rotation, and the cooperation is stable and the connection is convenient.

[0032] As one of the driving methods, refer to Figure 2 As shown, the adjusting shaft 22 penetrates the connecting shaft 21 and is axially movably connected to the connecting shaft 21, and the connecting shaft 21 is driven to rotate by the driving component 1; adjusting nuts 23 are provided at both ends of the connecting shaft 21, and the adjusting shaft 22 is fixed on the connecting shaft 21 after being pressed against the connecting shaft 21 by the adjusting nuts 23.

[0033] In this solution, the driving component 1 directly drives the connecting shaft 21. In fact, the driving component 1 can be combined with the connecting shaft 21 to form a hollow shaft reducer. At this time, the adjusting shaft 22 is directly passed through the connecting shaft 21 and is movable between the connecting shaft 21. The adjusting shaft 22 can be adjusted by the adjusting nuts 23 at both ends of the connecting shaft 21. The adjusted shaft 22 with a determined position can be fixed on the connecting shaft 21, and then the position of the agitator 3 can be fixed at the required stirring position. This installation method is convenient and has a simple structure.

[0034] Specifically, the driving component 1 is mounted on the bracket 4 , and a hollow structure 42 is provided at a position corresponding to the adjusting nut 23 . The hollow structure 42 is used for a hand or a tool to be inserted therein to rotate the adjusting nut 23 .

[0035] The bracket 4 is generally installed on the outside of the tank body to support the driving component 1, and the position of the bracket 4 corresponding to the adjusting nut 23 in this solution is a hollow structure 42, which is convenient for the user to turn the adjusting nut 23 by hand or with tools, and the operation is more convenient. When adjusting, people do not need to enter the tank body to operate, which is safer and more hygienic, and the operation and adjustment are very convenient and fast.

[0036] In another driving scheme, refer to Figure 1 , 3 4, it also includes a bracket 4 and a bearing 41 installed on the bracket 4, the driving component 1 is installed on the bracket 4, the bearing 41 is coaxially provided with a sleeve 5, the sleeve 5 is fixedly connected to the inner ring of the bearing 41, and the adjusting shaft 22 is inserted into the sleeve 5 to form a plug-in connection with the sleeve 5; adjusting nuts 23 are provided at both ends of the sleeve 5, and the adjusting shaft 22 is fixed on the sleeve 5 after being pressed by the adjusting nuts 23.

[0037] In this solution, the outer ring of the bearing 41 is installed on the bracket 4 and can be fixed with the bracket 4. The bracket 4 has a fulcrum, and the driving component 1 can be used as a solid shaft reducer. The output end of the driving component 1 is fixedly connected to the connecting shaft 21, and can directly transmit the output rotation to the connecting shaft 21. The bearing 41 on the bracket 4 cooperates with the sleeve 5 to play a stabilizing and supporting role. The tightness of the adjusting nuts 23 at both ends of the sleeve 5 can allow the adjusting shaft 22 to move and fix on the sleeve 5. When the adjusting shaft 22 is fixed on the sleeve 5 by the adjusting nut 23, the sleeve 5 and the bearing 41 cooperate to form a fulcrum, which plays a supporting role for the adjusting shaft 22, and the bearing 41 can be used to stabilize the rotation of the adjusting shaft 22.

[0038] Based on this solution, the position corresponding to the nut on the bracket 4 is set as a hollow structure 42, and the hollow structure 42 is used for a hand or a tool to insert and rotate the adjustment nut 23. The hollow structure 42 solution allows the user's hand or tool to more conveniently operate the adjustment nut 23, and it is more convenient to tighten and loosen, and it is also more convenient to grasp the adjustment shaft 22 to apply force and move.

[0039] In fact, depending on the number of bearings 41 and matching sleeves 5, multiple fulcrum solutions can be formed, and the driving component 1 can adopt a hollow shaft reducer or a solid shaft reducer (motor). The presence or absence of a fulcrum and the number of fulcrums can be combined with the use of a hollow shaft reducer or a solid shaft reducer to form a variety of implementation plans.

[0040] The above scheme describes a highly adjustable stirring structure, and applying it in a stirring device or a reaction device can form the following two schemes:

[0041] 1. A stirring device, comprising a container and a stirring structure mounted on the container, wherein the stirring structure adopts the height-adjustable stirring structure as described above.

[0042] 2. A reaction device, comprising a reaction kettle and a stirring device installed on the reaction kettle, wherein the stirring device comprises the height-adjustable stirring structure as described above.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
