[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1-6 A cleaning device for a reactor used in the synthesis of perfluoropolyether includes: a reactor 1 for the synthesis and processing of perfluoropolyether, a control panel 13, and a cleaning mechanism;

[0026] A circular plate 2 is rotatably connected to the top of the reactor 1. A sealed bearing is fixedly fitted on the circular plate 2. One side of the sealed bearing is fixedly connected to the reactor 1. A bracket 5 is fixedly connected to the top of the reactor 1. A cleaning mechanism is set on the bracket 5 and the circular plate 2 and is connected to the control panel 13 and the reactor 1. A stirring rod 12 is rotatably connected inside the reactor 1. The stirring rod 12 corresponds to the cleaning mechanism.

[0027] The cleaning mechanism includes a circular tube 3, a cleaning plate 4, a motor 6, a threaded rod 7, a moving plate 8, a ring plate 9, and a flexible hose 11. The circular tube 3 is slidably connected to the circular plate 2, and the cleaning plate 4 is installed at one end of the circular tube 3. The cleaning plate 4 is connected to the reactor 1. The cleaning plate 4 has a cavity and multiple spray holes on one side corresponding to the reactor 1. One end of the circular tube 3 communicates with the cavity. Scrapers are fixedly installed on both sides of the cleaning plate 4. Both scrapers are connected to the inner wall of the reactor 1. The two scrapers are located on both sides of the multiple spray holes. Through the coordinated design between the reactor 1, the circular plate 2, the stirring rod 12, the cleaning mechanism, and the control panel 13, it is possible not only to adjust the cleaning plate 4 up and down but also to adjust its rotation, thereby achieving the effect of cleaning the reactor 1. Moreover, it can prevent the cleaning plate 4 from immersing in the raw materials, thus improving its service life and product quality.

[0028] In this configuration, a motor 6 is fixedly mounted on the bracket 5, and a threaded rod 7 is fixedly connected to the output end of the motor 6. The motor 6 is connected to the control panel 13 and is used to drive the cleaning plate 4 up and down.

[0029] In this method, a movable plate 8 is threadedly connected to the threaded rod 7, and the movable plate 8 is slidably connected to the bracket 5. Through the threaded transmission between the threaded rod 7 and the movable plate 8, the effect of driving the round tube 3 up and down can be achieved.

[0030] In this configuration, a ring plate 9 is rotatably connected to the top of the movable plate 8. Sealed bearings are fixedly connected to both the inner and outer sides of the ring plate 9. One side of each of the two sealed bearings is fixedly connected to the movable plate 8, which improves the sealing performance and facilitates the rotation of the ring plate 9. The ring plate 9 is sleeved on the threaded rod 7. The bottom of the ring plate 9 is sealed to one end of the round tube 3. A groove 10 is provided on the movable plate 8, which corresponds to the ring plate 9. Through the action of the ring plate 9 and the round plate 2, the round tube 3 can be rotated with the stirring rod 12.

[0031] In this method, a through hole is provided on the ring plate 9, which corresponds to the round tube 3 and the groove 10, so as to facilitate the delivery of cleaning fluid into the round tube 3.

[0032] In this method, a hose 11 is sealed to the top of the movable plate 8. One end of the hose 11 extends into the groove 10 for conveying the cleaning fluid. The movable hose 11 is externally connected to one end of the liquid pump, and the other end of the liquid pump is connected to the cleaning fluid storage tank. The liquid pump is connected to the control panel 13.

[0033] In this method, a groove 14 is provided on one side of the stirring rod 12. The groove 14 is adapted to the round tube 3. Through the interaction between the groove 14 and the round tube 3, the stirring rod 12 can drive the round tube 3 to rotate.

[0034] Compared with related technologies, the reactor cleaning equipment for perfluoropolyether synthesis provided by this utility model has the following advantages:

[0035] This utility model provides a cleaning device for a reactor used in the synthesis of perfluoropolyether. Through the coordinated design of the reactor 1, the circular plate 2, the stirring rod 12, the cleaning mechanism and the control panel 13, it is possible not only to adjust the cleaning plate 4 up and down but also to adjust its rotation, thereby achieving the cleaning effect of the reactor 1. Moreover, it can prevent the cleaning plate 4 from immersing in the raw materials, thus improving the service life and product quality.

[0036] The working principle of the reactor cleaning equipment for perfluoropolyether synthesis provided by this utility model is as follows: When in use, first connect the power supply and drive the motor 6 through the preset program in the control panel 13;

[0037] First, the rotation of the stirring rod 12 by the second motor causes the slot 14 to correspond with the round tube 3. Then, the threaded rod 7 is rotated by the first motor 6 and is threadedly driven by the moving plate 8. The moving plate 8 drives the round tube 3 to slide down on the round plate 2 through the transmission of the ring plate 9, and the round tube 3 is connected to the slot 14. This enables the round tube 3 to drive the cleaning plate 4 to move up and down for adjustment.

[0038] While the circular tube 3 is connected to the slot 14, the slow drive of the electric motor 2, the transmission of the stirring rod 12, and the interaction between the slot 14 and the circular tube 3, along with the cooperation of the circular plate 2 and the ring plate 9, enable the circular tube 3 to rotate slowly with the stirring rod 12. At the same time, the circular tube 3 drives the cleaning plate 4 to rotate synchronously, thereby achieving the effect of rotating and adjusting the cleaning plate 4. At this time, the scrapers installed on both sides of the cleaning plate 4 can scrape and clean the dirt on the inner wall of the reactor 1.

[0039] Meanwhile, the cleaning fluid in the cleaning fluid storage tank is driven by the liquid pump connected to one end of the hose 11 and transported to the round tube 3 through the cooperation between the hose 11, the groove 10 and the through hole 1. At the same time, the cleaning fluid is transported to the cleaning plate 4 through the round tube 3 and sprayed out through multiple nozzles on one side and acted on the inner wall of the reactor 1, thereby achieving the effect of rinsing the reactor 1.

[0040] After the reactor 1 is cleaned, the motor 2 and the liquid pump are stopped. Through the reverse drive of the motor 6 and the cooperation between the threaded rod 7, the moving plate 8, the ring plate 9 and the support 5, the round tube 3 and the cleaning plate 4 can be moved to the top of the reactor 1, thereby preventing the cleaning plate 4 from being immersed in the raw materials.

[0041] Compared with related technologies, the cleaning equipment for the reactor used in the synthesis of perfluoropolyether provided by this utility model has the following advantages: through the cooperation of various components, it can not only clean the reactor, but also ensure that the cleaning plate 4 is immersed in the raw materials, thereby improving the service life and product quality. Moreover, it has a simple structure and is more practical.

[0042] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
