[0010] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0011] Reference Figures 3 to 6 One embodiment of the present invention provides a reflux stirred tank for perfluorobutyl fluoride, comprising a support frame 1, on which multiple electric push rods 2 are provided, which can push the tank cover 3 downward to make the bottom end of the tank cover 3 fit tightly against the top end of the tank body 20, thereby quickly sealing the tank body 20, creating a closed space for subsequent stirring operations, ensuring the sealing during the operation, and preventing the volatilization of materials inside the tank or the entry of external impurities. The output ends of the multiple electric push rods 2 are fixedly connected to the tank cover 3, and under the action of the electric push rods 2, they can fit tightly against the top end of the tank body 20 to achieve the sealing of the tank body 20, providing a closed reaction environment for the stirring of perfluorobutyl fluoride.
[0012] The lid 3 is equipped with a motor 4, whose drive end can drive the rotating rod 5 to rotate, providing power for the operation of the rotating rod 5 and subsequent connected structures. It is the core component of the power output of the entire stirring device. The drive end of the motor 4 is fixedly connected to the rotating rod 5, which rotates under the drive of the motor 4. On the one hand, it drives the scraper 6 to rotate, and on the other hand, it drives the bevel gear 8 to rotate, playing the role of transmitting power and driving the operation of related structures.
[0013] The rotating rod 5 is equipped with a scraper 6 on its outside. As the rotating rod 5 rotates, it comes into contact with the inner wall of the tank 20 during the rotation process, which can scrape and clean the inner wall of the tank 20, avoiding the residue of perfluorobutyl fluoride on the inner wall of the tank 20, ensuring the cleanliness of the inside of the tank 20 and the full utilization of the material. The rotating rod 5 is equipped with multiple connecting sleeves 7 on its outside, which provide rotation space and support for the rotating block 9, ensuring that the rotating block 9 rotates stably inside it, so that the rotating block 9 can rotate with the rotation of the bevel gear 10.
[0014] Multiple bevel gears 8 are provided on the outside of the rotating rod 5. As the rotating rod 5 rotates, it meshes with the bevel gear 10 and drives the bevel gear 10 to rotate. This transmits the rotational power of the rotating rod 5 to the bevel gear 10, enabling the subsequent structure to operate. Two rotating circular blocks 9 are rotatably connected inside the connecting sleeve 7. Driven by the bevel gear 10, they rotate inside the connecting sleeve 7. At the same time, its internal structure provides a foundation for the installation and operation of structures such as the fixed circular block 11 and the stirring rod 15. It is an important structure for connecting and supporting related components.
[0015] A bevel gear 10 is fixedly connected to the outside of the rotating block 9, meshing with a bevel gear 8. Driven by the bevel gear 8, the bevel gear 8 rotates, which in turn drives the rotating block 9 to rotate, thus transmitting power and driving the rotating block 9 to operate. Each pair of bevel gears 10 meshes with one of the bevel gears 8. A fixed block 11 is fixedly connected inside the rotating block 9, and a limiting component is provided inside to provide a base for the installation of the stirring rod 15. At the same time, the limiting component inside the fixed block 11 cooperates with the stirring rod 15 to limit and adjust the position of the stirring rod 15. A limiting component is provided inside the fixed block 11, and the stirring rod 15 is slidably connected to the outside of the fixed block 11. Under the action of the rotating block 9 and the fixed block 11, the stirring rod 15 rotates with the rotating block 9 to stir the perfluorobutyl fluoride in the tank. At the same time, its position can be adjusted as needed to adapt to different stirring requirements and ensure the uniformity of material stirring.
[0016] The stirring rod 15 is externally slidably connected to the inside of the rotating block 9, and the sliding rod 16 is externally slidably connected to the inside of the stirring rod 15. Two sliding rods 16 are slidably connected inside the rotating block 9. Under the pressure of the limiting ring 17, they move towards the center. When they move, they will press the limiting block 14, causing the limiting block 14 to move downward, thereby assisting in adjusting the position of the stirring rod 15. The limiting ring 17 is externally slidably connected to the rotating block 9. When it slides, it will press the two sliding rods 16 towards the center. By pressing the sliding rods 16, the limiting block 14 is pushed to move. This is the key operating component for realizing the position adjustment operation of the stirring rod 15.
[0017] Reference Figures 4 to 6 The limiting component includes a telescopic rod 12 with a spring 13 sleeved on the outside, which cooperates with the limiting block 14. When the limiting block 14 is squeezed, it can be compressed downward, providing space for the movement of the limiting block 14 and assisting in the adjustment of the position of the stirring rod 15. The outside of every two telescopic rods 12 is fixedly connected to the inside of the support frame 1. The outside of the telescopic rod 12 is sleeved with a spring 13. When the limiting block 14 is squeezed, it will be compressed downward together with the telescopic rod 12. When the squeezing force is removed, it can push the limiting block 14 to reset, thus cooperating with the telescopic rod 12 to realize the telescopic movement of the limiting block 14.
[0018] One end of the spring 13 is fixedly connected to the inside of the fixed circular block 11, and the other end of the spring 13 is fixedly connected to the outside of the limiting block 14. The far ends of the two telescopic rods 12 are fixedly connected to the limiting blocks 14. Under the pressure of the sliding rod 16, they move downward and cooperate with the stirring rod 15 to restrict the position of the stirring rod 15. When compressed, the restriction on the stirring rod 15 can be released, allowing the stirring rod 15 to be pulled out and the position of the stirring rod 15 to be adjusted. The outside of the limiting block 14 is slidably connected to the inside of the fixed circular block 11, and the outside of the limiting block 14 is connected to the inside of the stirring rod 15.
[0019] Reference Figures 1 to 3 The bottom of the support frame 1 is fixedly connected to the base plate 19, which provides the foundation and support for the installation of components such as the support frame 1, tank 20, water tank 21, and water pump 24, ensuring the stability of the bottom structure of the entire device. The top of the base plate 19 is equipped with the tank 20, which is the container for the stirring reaction of perfluorobutyl fluoride and provides reaction space for the material. The external cooling pipe 22 can control the internal temperature. The bottom of the tank 20 is equipped with a discharge hole 18. After the stirring operation of perfluorobutyl fluoride is completed, the processed material can be discharged through the discharge hole 18 for convenient subsequent processing or use, thereby improving the efficiency of operation.
[0020] A water tank 21 is fixedly connected to the top of the base plate 19, providing water for the cooling pipe 22 and storing water for heat exchange with the tank 20. It is the water storage component of the entire temperature control water circulation system. The cooling pipe 22 is fixedly connected to the top of the water tank 21 and is located outside the tank 20. Water drawn from the water tank 21 flows through the tank, exchanging heat with the tank 20 as it passes through the cooling pipe 22, thereby controlling the internal temperature of the tank 20 and ensuring that the perfluorobutyl fluoride reacts or is stirred under suitable temperature conditions. The bottom of the tank cover 3 is located at the top of the tank 20, and the interior of the cooling pipe 22 is located outside the tank 20. The outside of the scraper 6 is in contact with the inside of the tank 20. The bottom end of the water pump 24 is fixedly connected to the top of the bottom plate 19. It draws water from the water tank 21 through the delivery pipe 23 and then delivers the water to the cold pipe 22 to provide power for water circulation. It is the power component of the entire temperature control water circulation system. The output end of the water pump 24 is fixedly connected to one end of the cold pipe 22. The rear end of the water tank 21 is fixedly connected to the delivery pipe 23, which connects the water tank 21 and the water pump 24. It provides a channel for the water pump 24 to draw water from the water tank 21, so that water can be delivered from the water tank 21 to the water pump 24 and then enter the cold pipe 22. The water pump 24 is installed at the rear end of the delivery pipe 23.
[0021] Working principle: First, when stirring of perfluorobutyl fluoride is required, multiple electric push rods 2 are activated. The output end of the electric push rod 2 pushes the tank cover 3 downward until the bottom end of the tank cover 3 is tightly fitted with the top end of the tank body 20, completing the sealing of the tank body 20 and providing a closed space for subsequent stirring operations. Next, the motor 4 is activated, and the drive end of the motor 4 drives the rotating rod 5 to rotate. When the rotating rod 5 rotates, it drives the external scraper 6 to rotate. During the rotation, the scraper 6 comes into contact with the inside of the tank body 20, which can scrape and clean the inside of the tank body 20, preventing perfluorobutyl fluoride from remaining on the inner wall of the tank body 20.
[0022] On the other hand, the multiple bevel gears 8 outside the rotating rod 5 also rotate. Since every two bevel gears 10 are meshed with one of the bevel gears 8, the bevel gear 8 will drive the bevel gear 10 to rotate, thereby causing the rotating block 9 to rotate inside the connecting sleeve 7.
[0023] Then, during the stirring process, if it is necessary to adjust the position of the stirring rod 15, the limiting ring 17 can be operated. Sliding the limiting ring 17 will press the two sliding rods 16 towards the middle. After the sliding rods 16 are pressed, they will press the limiting block 14 downward. At this time, the spring 13 and the telescopic rod 12 will be compressed downward, so that the stirring rod 15 can be pulled out from the outside of the fixed block 11 and the inside of the rotating block 9, thereby realizing the adjustment of the position of the stirring rod 15 to adapt to different stirring needs.
[0024] Simultaneously, during the processing of perfluorobutyl fluoride, a water pump 24 is activated to control the internal temperature of the tank 20. The water pump 24 draws water from the water tank 21 through the delivery pipe 23 and then delivers the water to the cooling pipe 22. The cooling pipe 22 is located outside the tank 20. As the water flows through the cooling pipe 22, it exchanges heat with the tank 20, thereby controlling the internal temperature of the tank 20 and ensuring that the perfluorobutyl fluoride undergoes reaction or stirring operations in a suitable temperature environment. Finally, after the stirring operation of the perfluorobutyl fluoride is completed, the processed material can be discharged through the discharge hole 18 at the bottom of the tank 20 for subsequent processing or use.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
