Description

Technical Field

[0001] This utility model relates to the field of polytetrafluoroethylene resin technology, specifically to a polymerization reactor for polytetrafluoroethylene resin. Background Technology

[0002] Polymerization reactors used for polytetrafluoroethylene (PTFE) resins must possess characteristics such as corrosion resistance, high temperature resistance, and precise pressure control. Their design must meet the process requirements of the PTFE polymerization reaction. Stirring is crucial for the polymerization reactor, ensuring uniform mixing of reactants within the reactor, thereby improving reaction efficiency and product purity. The stirring device includes a stirring motor and a stirring shaft, with a stirring paddle mounted on the shaft. Stirring accelerates the reaction rate, reduces reaction time, and helps prevent localized accumulation or precipitation of reactants within the reactor.

[0003] The existing stirring mechanisms inside some polymerization reactors are relatively simple, requiring a long stirring time during use. Polytetrafluoroethylene resin requires high dispersibility, but traditional stirring can easily create dead zones, leading to localized overheating. This not only affects the stirring effect on the polytetrafluoroethylene resin but also the subsequent reaction time. Furthermore, prolonged stirring can increase the energy consumption of the polymerization reactor during use, reducing its applicability. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 As shown, a polymerization reactor for polytetrafluoroethylene resin includes a tank body 1. A feed pipe 2 is installed above the surface of the tank body 1, and a discharge pipe 4 is installed below the surface of the tank body 1. With the cooperation of the feed pipe 2 and the discharge pipe 4, the operator can fill the tank body 1 by feeding material into the tank body 1 through the feed pipe 2, and after mixing, the material can be discharged through the discharge pipe 4, thus facilitating the use of the polymerization reactor. A servo motor 5 is bolted to the top of the tank body 1. The output shaft of the servo motor 5 is fixedly connected to a rotating rod 6. The other end of the rotating rod 6 penetrates into the interior of the tank body 1 and is rotatably connected to the inner wall of the penetration point. A mixing mechanism 7 is installed on the surface of the rotating rod 6. The mixing mechanism 7 can move the material at the bottom of the tank body 1 upwards and compress the material at the top downwards, thus facilitating the mixing of the material and effectively... The applicability of the polymerization reactor has been improved. An auxiliary mechanism 8 is installed on the surface of the tank body 1. The auxiliary mechanism 8 can mix the material through the cooperation of the side plate, so that the material can be further disturbed, thereby improving the mixing effect of the material. The upper and lower parts of the rotating rod 6 are fixedly connected to the stirring frame 3. The stirring frame 3 can rotate with the cooperation of the rotating rod 6, so that the stirring frame 3 can stir the material laterally, thereby disrupting the flow of material and improving the mixing effect of the material. A sealed bearing seat 10 is installed below the surface of the rotating rod 6. The surface of the sealed bearing seat 10 is used in conjunction with the inner wall of the tank body 1. Under this action, the sealing bearing seat 10 can support one end of the rotating rod 6, so that it can be more stable when rotating, and avoid the disturbance effect of the material due to insufficient stability during rotation.

[0022] The mixing mechanism 7 includes rotating blades 71 fixed above the surface of the rotating rod 6, and mixing blades 72 fixedly connected below the surface of the rotating rod 6. There are several rotating blades 71 and several mixing blades 72, both with an inclined structure design. The inclination direction of the rotating blades 71 is opposite to that of the mixing blades 72. Under this action, when the rotating rod 6 rotates, the mixing blades 72 can move the material upwards into the inner cavity of the tank 1, while the rotating blades 71 push the material downwards, thus further agitating the material in the polymerization reactor. Furthermore, with the assistance of the mixing blades 72, air bubbles in the material can be squeezed out, facilitating subsequent use. Several guide plates 73 are fixedly connected to the inner wall of the tank 1. All guide plates 73 have an inclined design, which assists in moving the material at the bottom of the inner cavity of the tank 1 upwards, effectively improving the applicability of the polymerization reactor.

[0023] The auxiliary mechanism 8 includes a stepper motor 81 mounted on the surface of the tank 1. The output shaft of the stepper motor 81 passes through the interior of the tank 1 and is rotatably connected to the inner wall of the penetration point. A fixed rod 82 is fixedly connected to the output shaft of the stepper motor 81. A rotating plate 83 is fixedly connected to the surface of the fixed rod 82. There are several rotating plates 83. Under this action, the fixed rod 82 can be driven by the stepper motor 81 to rotate the rotating plate 83, thereby disturbing the material in the middle part of the tank 1. This not only helps the material move upward into the inner cavity of the tank 1, but also helps to stir the material by lateral rotation, thereby improving the disturbance effect on the material. A support frame 9 is fixedly connected to the surface of the tank 1. The surface of the support frame 9 is used in conjunction with the surface of the stepper motor 81. The support frame 9 can support the stepper motor 81, making it more stable during use and preventing it from being unstable during use and affecting normal use.

[0024] It is worth noting that the technical features such as tank 1, servo motor 5 and stepper motor 81 proposed in this technical solution should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0025] Working principle: First, the materials to be mixed are discharged into the tank 1 through the feed pipe 2. Then, the servo motor 5 is turned on to drive the rotating rod 6 to rotate. With the cooperation of the rotating rod 6 and the mixing blade 72, the materials are stirred and mixed, causing the materials to move upward. With the cooperation of the guide plate 73, the movement of the materials is further assisted. With the cooperation of the rotating blade 71, the air bubbles on the surface of the materials can be squeezed, thereby facilitating the subsequent effective mixing of the materials. Then, the stepper motor 81 is turned on. With the cooperation of the stepper motor 81 and the fixed rod 82, the rotating plate 83 pushes and agitates the materials, thereby causing some materials to continue to move upward and some materials to move downward, further improving the agitation effect on the materials and effectively improving the mixing effect of the polymerization reactor.
