[0024] Specifically, after the reactor stirring device provided in the present embodiment is installed on the reactor, the end of the stirring shaft 4 away from the movable bracket 2 extends into the reactor together with the stirring assembly 6. At this time, the first driving member 3 and the second driving member 5 are respectively started to stir the material inside the reactor; after the first driving member 3 is started, the movable bracket 2 rotates under the drive of the first driving member 3, and the movable bracket 2 drives the stirring shaft 4 to move so that the end of the stirring shaft 4 provided with the stirring assembly 6 makes a circular motion, and after the second driving member 5 is started, the stirring shaft 4 is driven to rotate on the movable bracket 2 and drives the stirring assembly 6 to rotate, so that the stirring assembly 6 makes a circular motion in the reactor and rotates around the axial direction of the stirring shaft 4 at the same time, and the stirring blades contact the material in the reactor so that the material is stirred by forces in multiple directions, ensuring that the material in the reactor is fully mixed, and avoiding that the material is stirred by forces in only one direction for a period of time and then the materials move relatively synchronously, which is beneficial to improving the mixing efficiency of the materials in the reactor.

[0025] Please combine Figure 1 and Figure 2The movable bracket 2 includes a rotating shaft 21, and the mounting bracket 1 is provided with a first mounting hole matched with the rotating shaft 21, and the rotating shaft 21 is matched with the output end of the first driving member 3. The rotating connection between the movable bracket 2 and the mounting bracket 1 is realized by the matching of the rotating shaft 21 and the first mounting hole, so that the movable bracket 2 can rotate smoothly on the mounting bracket 1, and the rotating seat is matched with the output end of the first driving member 3, so that the power output by the first driving member 3 can be smoothly transmitted to the movable bracket 2 and drive the movable bracket 2, which is conducive to improving the stability of the movable bracket 2 when it moves. The first driving member 3 can be a motor.

[0026] In detail, the movable bracket 2 also includes a connecting portion 22 and a mounting portion 23 which are sequentially connected to the rotating shaft 21, the mounting portion 23 is provided with a second mounting hole which matches with the stirring shaft 4, the second driving member 5 is arranged on the mounting portion 23 and the stirring shaft 4 matches with the output end of the second driving member 5. The movable bracket 2 is composed of the rotating shaft 21, the connecting portion 22 and the mounting portion 23 which are connected to each other, wherein the stirring shaft 4 is mounted in the second mounting hole on the mounting portion 23 and the second driving member 5 is arranged on the mounting portion 23, and the stirring shaft 4 can rotate in the second mounting hole under the drive of the second driving member 5 through the matching between the stirring shaft 4 and the output end of the second driving member 5, so that the matching between the stirring shaft 4 and the movable bracket 2 is reliable and the stirring shaft 4 can rotate smoothly, and the second driving member 5 can select a motor.

[0027] like Figure 2 As shown, the mounting bracket 1 is provided with a rotatable first rotating disk 11, and the first rotating disk 11 is provided with a first through hole for the agitator shaft 4 to pass through, and the axial direction of the first through hole coincides with the axis of the agitator shaft 4. The rotation axis of the first rotating disk 11 arranged on the mounting bracket 1 coincides with the rotation axis of the movable bracket 2, and the first rotating disk 11 is provided with a first through hole for matching with the agitator shaft 4. When the agitator shaft 4 rotates driven by the movable bracket 2, the first rotating disk 11 rotates on the mounting bracket 1 along with the movement of the agitator shaft 4. The stirring supported by the first rotating disk 11 can prevent the agitator shaft 4 from being tilted unexpectedly, so that the agitator shaft 4 maintains a preset tilt angle during the rotation process.

[0028] Specifically, the mounting bracket 1 is further provided with a support portion 12, the support portion 12 is located between the movable bracket 2 and the first rotating disk 11, and a rotatable second rotating disk 13 is provided on the support portion 12, a second through hole for the stirring shaft 4 to pass through is provided on the second rotating disk 13, and the axial direction of the second through hole coincides with the axis of the stirring shaft 4. The second rotating disk 13 is arranged on the support portion 12 located between the movable bracket 2 and the first rotating disk 11, and a second through hole matching with the stirring shaft 4 is provided on the second rotating disk 13, and the end of the stirring shaft 4 away from the movable bracket 2 passes through the second rotating disk 13 and the first rotating disk 11 in sequence and then extends into the reactor, and when the stirring shaft 4 rotates, the second rotating disk 13 rotates on the support portion 12 along with the movement of the stirring shaft 4, and the second rotating disk 13 limits the stirring shaft 4 to further improve the stability of the stirring shaft 4 during rotation, and prevent the stirring shaft 4 from shaking.

[0029] like Figure 1 and Figure 2 As shown, a limiting cylinder 41 is sleeved on the stirring shaft 4, and the limiting cylinder 41 is located between the first rotating disk 11 and the second rotating disk 13, and the two ends of the limiting cylinder 41 are respectively in contact with the first rotating disk 11 and the second rotating disk 13. The limiting cylinder 41 provided on the stirring shaft 4 prevents the stirring shaft 4 from sliding along the axial direction of the stirring shaft 4 relative to the first rotating disk 11 or the second rotating disk 13, which is beneficial to improving the stability of the coordination between the stirring shaft 4 and the first rotating disk 11 and the second rotating disk 13, and avoids the stirring assembly 6 from colliding with the reactor due to the up and down sliding of the stirring shaft 4 during the operation, which is beneficial to improving the stability of the operation of the stirring device of the reactor.

[0030] Please refer to Figure 1 and Figure 2 The mounting bracket 1 further comprises a mounting tube 14, the first rotating disk 11 is rotatably disposed on the mounting tube 14, an end of the mounting tube 14 away from the first rotating disk 11 is provided with an extension portion, and the extension portion is provided with a plurality of third mounting holes spaced along the circumference of the mounting tube 14. The mounting tube 14 disposed on the mounting bracket 1 is used to connect the mounting bracket 1 with the reactor, and the mounting bracket 1 can be fixed on the reactor by passing the third mounting holes through the connecting member and cooperating with the holes on the reactor, thereby installing the mounting seat bracket on the reactor and keeping the position of the mounting seat bracket on the reactor stable.

[0031] like Figure 3As shown, the first stirring blade 62 is provided with a through hole 63 penetrating the first stirring blade 62, and the through hole 63 is arranged close to the mounting tube 14. The through hole 63 allows part of the material in the reactor to pass through during the operation of the stirring component 6, and the moving direction of the material passing through the through hole 63 is different from the moving direction of the material contacting the first stirring blade 62, so that the material in the reactor is fully mixed, and at the same time, it is beneficial to reduce the resistance encountered by the stirring component 6 during the operation, and improve the stability of the stirring component 6 during the operation.

[0032] In detail, the stirring assembly 6 further includes a second stirring blade 64, which is disposed at one end of the first stirring blade 62 away from the mounting cylinder 14, and the angle between the first stirring blade 62 and the second stirring blade 64 is an acute angle. The second stirring blade 64 is disposed on the first stirring blade 62 and is at a certain angle to the first stirring blade 62. With the movement of the stirring assembly 6, the first stirring blade 62 and the second stirring blade 64 simultaneously stir the material in the reactor, and the moving direction of the material under the push of the first stirring blade 62 is different from the moving direction under the push of the second stirring blade 64, so that the material in the reactor can be stirred by multiple forces in different directions, further improving the mixing efficiency.

[0033] Please combine Figure 1 and Figure 2 In this embodiment, three stirring components 6 are provided on the stirring shaft 4, and the three stirring components 6 are arranged at intervals on the stirring shaft 4 along the axial direction of the stirring shaft 4. The three stirring components 6 arranged at intervals on the stirring shaft 4 are used to stir the materials at different heights in the reactor respectively, so as to prevent part of the materials from being deposited at the bottom of the reactor or being retained in some areas of the reactor to cause uneven mixing of the materials, thereby ensuring that the mounting seat bracket has a good mixing effect.
