Description

Technical Field

[0001] The utility model relates to the technical field of polymerization kettles, in particular to a stirrer for a fluorochemical polymerization kettle. Background Technique

[0002] A polymerization kettle is a vertical cylindrical high-pressure kettle, which can be used to prepare high-molecular compounds. The fluorochemical process can produce fluorochemical products, and the products can be used in various industrial fields. In the industrial process of fluorochemicals, raw materials usually need to react through a polymerization kettle. When in use, the raw materials need to be added into the polymerization kettle, and the raw materials naturally diffuse in the polymerization kettle to produce a mixing reaction.

[0003] However, relying only on the natural diffusion of the raw materials in the polymerization kettle for mixing reaction, the reaction speed is relatively slow. Using a stirring mechanism such as a stirring rod to stir the raw materials in the polymerization kettle can improve the reaction speed. However, due to the large volume inside the polymerization kettle, using a stirring rod that fills the inner cavity of the polymerization kettle to stir all the raw materials simultaneously, since the stirring rod occupies a relatively large amount of space inside the polymerization kettle, the stirring rod will affect the volume of the polymerization kettle and the process of adding raw materials; and the stirring direction of the stirring rod in the existing stirring mechanism is single, and the stirring efficiency is relatively low. Summary of the Utility Model

[0004] (1). Technical Problems to be Solved

[0005] The technical problem to be solved by the utility model is that currently, in order to improve the reaction speed and fully stir every part of the raw materials in the polymerization kettle simultaneously, the stirring rod occupies a relatively large amount of space in the polymerization kettle, which will affect the volume of the polymerization kettle and the process of adding raw materials into the polymerization kettle; and the stirring direction is single, which will reduce the stirring efficiency.

[0007] To solve the above technical problems, the technical solution provided by the present utility model is as follows: A stirrer for a fluorochemical polymerization kettle, comprising a connection structure. The connection structure includes a connecting rod fixedly connected to the polymerization kettle, and further includes a reciprocating rod. There are not less than one and evenly arranged stirring rods fixedly connected to the reciprocating rod. A motor box is provided at the lower end of the connecting rod. A fixing plate is fixedly connected to the lower end of the motor box. A circumferential vertical reciprocating structure for driving the stirring rod to move is provided at the lower end of the fixing plate. A driving motor for driving the circumferential vertical reciprocating structure is provided in the motor box. The output end of the driving motor is provided with a shaft rod penetrating through the bottom of the fixing plate. A first bevel gear is fixedly connected to the shaft rod.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1 , Figure 2 and Figure 3 shown, a stirrer for a fluorochemical polymerization kettle includes a connection structure. The connection structure includes a connecting rod 1 fixedly connected to the polymerization kettle, and further includes a reciprocating rod 13. Not less than one and evenly arranged stirring rods 14 are fixedly connected to the reciprocating rod 13. The cross-section of the stirring rod 14 can be circular or square. A motor box 2 is provided at the lower end of the connecting rod 1. A fixed plate 3 is fixedly connected to the lower end of the motor box 2. A circumferential vertical reciprocating structure for driving the stirring rod 14 to move is provided at the lower end of the fixed plate 3. A driving motor for driving the circumferential vertical reciprocating structure is provided in the motor box 2.

[0024] Through the above structure, the circumferential vertical reciprocating structure is installed in the polymerization kettle through a connection mechanism. How to drive the stirring rod 14 to move is as follows:

[0025] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 andFigure 6 As shown, a shaft rod 5 penetrating the bottom of the fixing plate 3 is provided at the output end of the driving motor. A bearing cooperating with the shaft rod 5 is provided inside the fixing plate 3. A first bevel gear 4 is fixedly connected to the shaft rod 5. The first bevel gear 4 is arranged below the fixing plate 3. A second bevel gear 7 meshing with the first bevel gear 4 is rotatably arranged on one side of the shaft rod 5. A straight rod fixedly connected to the second bevel gear 7 is rotatably arranged on the shaft rod 5. A rotating rod 6 is fixedly connected to the lower end of the shaft rod 5. A rotating plate 8 is fixedly connected to one end of the rotating rod 6. A first rotating shaft 10 and a second rotating shaft 11 are arranged inside the rotating plate 8. A turntable 9 is fixedly connected to one end of each of the first rotating shaft 10 and the second rotating shaft 11. The end of the first rotating shaft 10 opposite to the turntable 9 is fixedly connected to the second bevel gear 7. A crank 12 fixedly connected to a reciprocating rod 13 is arranged on one side of the turntable 9. The crank 12 is rotatably connected to both turntables 9. The reciprocating rod 13 is perpendicular to the crank 12.

[0026] Through the above structure, the circumferential vertical reciprocating structure can drive the stirring rod 14 to perform a circumferential motion and a reciprocating motion in the vertical direction inside the polymerization kettle.

[0027] When the present utility model is specifically implemented, during use, first fixedly install the connecting rod of the connecting structure at a suitable position on the polymerization kettle, so that the stirring rod is located in the inner cavity of the polymerization kettle. When raw materials for reaction are needed, first add the raw materials into the inner cavity of the polymerization kettle. During the adding process, the space occupied by the stirring rod in the polymerization kettle is small, and the stirring rod is located on one side of the center position of the inner cavity of the polymerization kettle, which will not affect the process of adding raw materials. After the raw materials are added, start the polymerization kettle and start stirring;

[0028] During stirring, the driving motor drives the shaft rod to rotate. The first bevel gear will rotate at the lower end of the fixing plate, and the shaft rod will also drive the second bevel gear to perform a circular motion around the first bevel gear. Since the first bevel gear meshes with the second bevel gear, that is, the second bevel gear will rotate in a circle while rotating itself; the shaft rod can also drive the rotating plate to perform a circular motion around the first bevel gear through the rotating rod. The rotating plate can rotate around the shaft rod synchronously with the second bevel gear. During the rotation process, the rotating first bevel gear can drive the turntable to rotate through the first rotating shaft. With the cooperation of the second rotating shaft, the two turntables rotate synchronously under the action of the crank. The crank can drive the reciprocating rod to perform a reciprocating motion in the vertical direction. The rotating plate can drive the reciprocating rod to perform a circular motion around the shaft rod, and further drive the stirring rod to perform a circular motion around the axis and a reciprocating motion in the vertical direction, so as to stir the raw materials in a circle in the inner cavity of the polymerization kettle, and the raw materials can be stirred up and down during the circular motion process, which can improve the stirring efficiency.
