[0002] In many fields such as chemical engineering, pharmaceuticals, and experiments, reaction kettles are inevitably used. An agitator device is installed inside the reaction kettle to stir the reaction liquid in the reaction kettle, so as to make the reaction liquid in the reaction kettle mix evenly and ensure the reaction effect.

[0003] The agitator device of the reaction kettle in the prior art generally includes a stirring shaft, and stirring wings for facilitating stirring are installed at the lower end of the stirring shaft. The structure is simple. Since the stirring wings are installed at the bottom of the reaction kettle, the stirring effect is poor. For reactions with crystal precipitation, the crystals often crystallize and fix on the inner wall of the reaction kettle, resulting in uneven reaction and difficult discharge of the crystals. Therefore, it is very inconvenient to use. Therefore, those skilled in the art have provided an agitator device for a reaction kettle to solve the problems raised in the above background art. Utility Model Content

[0004] To solve the problems raised in the above background art, this application provides an agitator device for a reaction kettle.

[0005] The agitator device for a reaction kettle provided by this application adopts the following technical solutions:

[0006] An agitator device for a reaction kettle includes a reaction kettle body. A transmission shaft is arranged at the axis center of the reaction kettle body. A motor is arranged above the transmission shaft. A rotating rod is arranged below the transmission shaft. The rotating rod is located inside the reaction kettle body. Connecting rods are equidistantly arranged around the rotating rod.

[0007] A gear ring is arranged inside the reaction kettle body. A first gear and a second gear are arranged inside the gear ring. There are multiple first gears and second gears. The multiple first gears and second gears mesh with each other. One side of the second gear meshes with the inner wall of the gear ring.

[0008] Multiple rotating components are arranged. The multiple rotating components are respectively arranged inside the multiple first gears and second gears. A stirring component is arranged on the surface of the rotating component. The rotating component rotates below the rotating rod.

[0009] In some embodiments, a reinforcing rod is arranged above the rotating rod. The reinforcing rod is sleeved on the surface of the transmission shaft. Connecting blocks are arranged below the periphery of the reinforcing rod. The lower part of the connecting block is fixedly connected to the outer wall of the gear ring.

[0010] In some embodiments, the gear ring is located above the stirring assembly, and the outer wall of the gear ring is in contact with the inner wall of the reactor body.

[0011] In some embodiments, the rotating assembly includes first limiting blocks respectively located inside the first gear and the second gear. A first linkage rod is fixedly connected above the first limiting block. The upper part of the first linkage rod is fixedly connected to the lower part of the connecting rod. A second limiting block is arranged below the first limiting block, and a second linkage rod is arranged below the second limiting block.

[0012] In some embodiments, a limiting block is fixedly connected to the outer wall of the second limiting block. The limiting block is clamped with the inner walls of the first gear and the second gear. A plurality of fixing plates are arranged inside the first gear and the second gear. One sides of the plurality of fixing plates are respectively in contact with one sides of the first linkage rod and the first limiting block. A fixing bolt is arranged inside the fixing plate.

[0014] In summary, the present application includes the following beneficial technical effects:

[0015] (1) The connecting rod drives a plurality of rotating assemblies to rotate inside the reactor body.

The first gear and the second gear drive the rotating assemblies and the stirring assembly to rotate during the self-rotation process, improving the stirring efficiency of the rotating assemblies and the stirring assembly. By improving the stirring efficiency of multiple groups of stirring assemblies, the attachment of crystallization products to the inner wall of the reactor can be greatly reduced, and the accumulation of crystallization products can be reduced, thereby facilitating the discharge of the crystallization products from the inside of the reactor.

[0016] (2) The first gear and the second gear clamp the second limiting block through the limiting block, so that the second limiting block rotates following the first gear and the second gear. The fixing plates limit the first limiting block and the second limiting block, so that the first limiting block and the second limiting block both work inside the first gear and the second gear, increasing stability.

Detailed implementation manners

[0023] The following will further describe the present application in detail with reference to the attached Figures 1-5 drawings.

[0024] The embodiment of the present application discloses a stirring device for a reactor. Referring to Figures 1-5 , a stirring device for a reactor includes a reactor body 1, a rotating assembly 5 and a gear ring 8. A transmission shaft 3 is arranged at the axis center of the reactor body 1, a motor 2 is arranged above the transmission shaft 3, a rotating rod 4 is arranged below the transmission shaft 3, the rotating rod 4 is located inside the reactor body 1, connecting rods 41 are equidistantly arranged around the rotating rod 4, the gear ring 8 is arranged inside the reactor body 1, a first gear 6 and a second gear 7 are arranged inside the gear ring 8, there are multiple first gears 6 and second gears 7, the multiple first gears 6 and second gears 7 mesh with each other, one side of the second gear 7 meshes with the inner wall of the gear ring 8, there are multiple rotating assemblies 5, the multiple rotating assemblies 5 are respectively arranged inside the multiple first gears 6 and second gears 7, a stirring assembly 9 is arranged on the surface of the rotating assembly 5, and the rotating assembly 5 rotates below the rotating rod 4;

[0025] In the implementation process, when the staff needs to use the stirring device, the worker installs the motor 2 above the reaction kettle body 1, and then the motor 2 drives the rotating rod 4 to rotate through the transmission shaft 3 at the output end. During the rotation of the rotating rod 4, the connecting rod 41 is driven to rotate, and the connecting rod 41 drives a plurality of rotating components 5 to rotate inside the reaction kettle body 1. By changing the position of the rotating components 5, the position of the stirring component 9 inside the reaction kettle body 1 is changed, and the stirring range is increased by the moving stirring component 9;

[0026] When the rotating component 5 rotates inside the reaction kettle body 1, the first gear 6 and the second gear 7 mesh and move through the gear ring 8, so that the first gear 6 and the second gear 7 rotate selflessly when moving inside the gear ring 8. The first gear 6 and the second gear 7 drive the rotating component 5 and the stirring component 9 to rotate during the self-rotation process, improving the stirring efficiency of the rotating component 5 and the stirring component 9.

[0027] Among them, a reinforcing rod 42 is arranged above the rotating rod 4. The reinforcing rod 42 is sleeved on the surface of the transmission shaft 3. Connecting blocks 43 are arranged below the four sides of the reinforcing rod 42, and the lower part of the connecting block 43 is fixedly connected to the outer wall of the gear ring 8;

[0028] The transmission shaft 3 rotates inside the reinforcing rod 42. The connecting block 43 is used for fixing the reinforcing rod 42 and the gear ring 8. The reinforcing rod 42 limits the rotating rod 4, increasing the stability of the transmission shaft 3 during rotation. The reinforcing rod 42 and the rotating rod 4 are connected through a bearing seat, reducing the friction between the rotating rod 4 and the reinforcing rod 42.

[0029] Preferably, the gear ring 8 is located above the stirring component 9. The outer wall of the gear ring 8 fits with the inner wall of the reaction kettle body 1. The gear ring 8 is used to drive the rotation of the first gear 6 and the second gear 7. The gear ring 8 is fixed inside the reaction kettle body 1 to increase stability.

[0030] Specifically, the rotating component 5 includes first limit blocks 52 respectively located inside the first gear 6 and the second gear 7. A first linkage rod 51 is fixedly connected above the first limit block 52. The upper part of the first linkage rod 51 is fixedly connected to the lower part of the connecting rod 41. A second limit block 53 is arranged below the first limit block 52, and a second linkage rod 54 is arranged below the second limit block 53;

[0031] The rotating assembly 5 is divided into a fixed first linkage rod 51 and a rotating second linkage rod 54. The upper part of the first linkage rod 51 is fixed to the lower part of the connecting rod 41. When the connecting rod 41 drives the first linkage rod 51 to move, it drives the first gear 6 and the second gear 7 to move. The lower part of the first linkage rod 51 is connected to the first gear 6 and the second gear 7 through the first limiting block 52. A bearing ring is installed on the outer wall of the first limiting block 52, so that the first gear 6 and the second gear 7 slide on the surface of the first limiting block 52.

[0032] More specifically, a limiting block 531 is fixedly connected to the outer wall of the second limiting block 53. The limiting block 531 is clamped with the inner walls of the first gear 6 and the second gear 7. A fixing disk 61 is arranged inside each of the first gear 6 and the second gear 7. There are multiple fixing disks 61. One sides of the multiple fixing disks 61 are respectively attached to one sides of the first linkage rod 51 and the first limiting block 52. A fixing bolt 62 is arranged inside the fixing disk 61;

[0033] The first gear 6 and the second gear 7 clamp the second limiting block 53 through the limiting block 531, so that the second limiting block 53 rotates following the first gear 6 and the second gear 7. The fixing disk 61 limits the first limiting block 52 and the second limiting block 53, so that both the first limiting block 52 and the second limiting block 53 work inside the first gear 6 and the second gear 7, increasing stability. The fixing bolt 62 can facilitate the disassembly of the fixing disk 61, and facilitate the maintenance and replacement of the first limiting block 52 and the second limiting block 53 limited by the fixing disk 61.

[0034] Further, in the implementation process, the stirring assembly 9 includes a fixed shaft 91 sliding on the surface of the second linkage rod 54. Stirring blades 92 and threaded rods 93 are arranged on the surface of the fixed shaft 91. Multiple stirring blades 92 and threaded rods 93 are arranged at equal intervals;

[0035] The fixed shaft 91 can slide on the surface of the second linkage rod 54, which is convenient for adjusting the height of the stirring blades 92. The stirring blades 92 with different heights are located inside the reaction kettle body 1, so as to increase the contact area between the stirring blades 92 and the liquid, thereby improving the stirring efficiency. The threaded rod 93 rotates and inserts into the inside of the fixed shaft 91. One end of the threaded rod 93 abuts against the outer wall of the second linkage rod 54, and is used for fixing the fixed shaft 91.

[0036] The implementation principle of the stirring device of a reactor in an embodiment of the present application is as follows: When the staff needs to use the stirring device, the worker installs the motor 2 above the reactor body 1, and then the motor 2 drives the rotating rod 4 to rotate through the transmission shaft 3 at the output end. During the rotation of the rotating rod 4, the connecting rod 41 is driven to rotate, and the connecting rod 41 drives a plurality of rotating components 5 to rotate inside the reactor body 1. By changing the position of the rotating component 5, the position of the stirring component 9 inside the reactor body 1 is changed, and the stirring range is increased by the moving stirring component 9. When the rotating component 5 rotates inside the reactor body 1, the first gear 6 and the second gear 7 move meshingly through the gear ring 8, so that the first gear 6 and the second gear 7 rotate self - when moving inside the gear ring 8. During the self - rotation process of the first gear 6 and the second gear 7, the rotating component 5 and the stirring component 9 are driven to rotate, improving the stirring efficiency of the rotating component 5 and the stirring component 9.
