Abstract
Description
Technical Field
[0001] This utility model relates to the field of granulation equipment, and in particular to a granulation equipment for perfluorosulfonic acid resin powder. Background Technology
[0002] Perfluorosulfonic acid resin powder granulation is the process of processing perfluorosulfonic acid resin powder into particles with a specific shape and size through a specific process. Granulated perfluorosulfonic acid resin particles have better flowability and operability in storage, transportation, and subsequent processing, and are widely used in chemical, energy, and other fields. Fluidized bed granulators are one of the commonly used equipment in the perfluorosulfonic acid resin powder granulation process. They use hot air to fluidize the powder within a bed, while simultaneously injecting a binder to agglomerate the powder particles and form the desired granules. This granulation method has advantages such as high granulation efficiency and good particle uniformity.
[0003] However, a significant drawback of existing technology exists in the use of fluidized bed granulators: the inner end of the observation window glass is prone to accumulating debris during operation. Because the powder is in a fluidized state during granulation, it easily splashes onto the observation window glass, and binders and other substances may also remain on the glass surface. This debris significantly hinders operators' ability to clearly observe the internal workings of the fluidized bed granulator through the observation window, such as the fluidization state of the powder and the particle formation process. Consequently, operators may be unable to accurately and promptly grasp the equipment's operating status and granulation quality, affecting production process control and product quality. Therefore, this application proposes a perfluorosulfonic acid resin powder granulation device to solve the above problems. Utility Model Content
[0004] The main objective of this invention is to provide a perfluorosulfonic acid resin powder granulation device that can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A perfluorosulfonic acid resin powder granulation device includes a fluidized bed granulator. Several observation windows are fixedly inserted into the fluidized bed granulator. A rotation limiting assembly is rotatably mounted on each observation window. The rotation limiting assembly consists of a rotating ring, a collar, connecting rods, protrusions, and a spring. The collar is located inside the rotating ring and is coaxial with it. There are two connecting rods, both fixedly connected to the rotating ring and the collar. There are two protrusions, symmetrically fixedly mounted on the inner wall of the collar. The spring is fixedly mounted on the outer end of the collar. A cleaning assembly is movably mounted on the observation windows and the rotation limiting assembly. The cleaning assembly consists of a base shaft, a rubber scraper, and an anti-detachment baffle. The rubber scraper is fixedly embedded in the inner end of the base shaft, and the anti-detachment baffle is fixedly mounted on the outer end of the base shaft.
[0007] Preferably, the fluidized bed granulator has two support legs symmetrically fixedly installed.
[0008] Preferably, the observation window is composed of a circular tube and transparent glass. The circular tube is fixedly inserted into the fluidized bed granulator, and the transparent glass is fixedly installed on the inner wall of the circular tube. A through hole is provided at the axis of the transparent glass.
[0009] Preferably, the rotating ring on the rotating limiting assembly is rotatably sleeved on the outside of the circular tube, and the connecting rod is located at the outer end of the circular tube.
[0010] Preferably, the base shaft on the cleaning component is rotatably mounted in a through hole in the transparent glass, and the base shaft passes through the collar at the same time. Two guide rail slots are symmetrically opened on the outer wall of the base shaft. The base shaft is movably sleeved on the protrusion through the guide rail slots. The rubber scraper is in close contact with the inner end of the transparent glass, and the rubber scraper is fixedly connected to the base shaft by screws. The anti-detachment baffle is located outside the spring.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] By installing a rotation limiting assembly consisting of a rotating ring, a collar, a connecting rod, a protrusion, and a spring on the observation window, and a cleaning assembly consisting of a base shaft, a rubber scraper, and an anti-detachment baffle, when debris adheres to the inner end of the observation window glass, the operator can rotate the rotating ring, causing the collar to rotate synchronously. The protrusion inside the collar drives the base shaft to rotate through the guide rail groove, allowing the rubber scraper to scrape and clean the inner surface of the transparent glass, effectively removing attached powder, adhesives, and other debris. At the same time, the spring ensures that the rubber scraper is in close contact with the inner end of the transparent glass, ensuring the cleaning effect of the rubber scraper on the transparent glass. This allows the operator to clearly observe the internal workings of the fluidized bed granulator through the observation window, promptly and accurately grasp the equipment's operating status and granulation quality, and effectively improve the control precision of the production process and product quality.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] Please see Figures 1-4 As shown, a perfluorosulfonic acid resin powder granulation device includes a fluidized bed granulator 1. Several observation windows 2 are fixedly inserted into the fluidized bed granulator 1. A rotation limiting assembly 3 is rotatably mounted on each observation window 2.

There are two protrusions 12, symmetrically fixedly mounted on the inner wall of the collar 10. The springs 13 are fixedly mounted on the outer end of the collar 10. A cleaning assembly 4 is movably mounted on the observation windows 2 and the rotation limiting assembly 3. The cleaning assembly 4 consists of a base shaft 14, a rubber scraper 15, and an anti-detachment baffle 16. The rubber scraper 15 is fixedly embedded in the inner end of the base shaft 14, and the anti-detachment baffle 16 is fixedly mounted on the outer end of the base shaft 14. The cleaning assembly 4 is achieved by setting [the cleaning assembly 3] on the observation windows 2. The rotating limiting assembly 3, consisting of a rotating ring 9, a collar 10, a connecting rod 11, a protrusion 12, and a spring 13, and the cleaning assembly 4, consisting of a base shaft 14, a rubber scraper 15, and an anti-detachment baffle 16, allows the operator to rotate the rotating ring 9 when debris adheres to the inner end of the glass in the observation window 2. This causes the collar 10 to rotate synchronously, and the protrusion 12 inside the collar 10 drives the base shaft 14 to rotate via the guide rail groove 17. This allows the rubber scraper 15 to scrape and clean the inner surface of the transparent glass 7, effectively removing attached powder, adhesives, and other debris. At the same time, the spring 13 ensures that the rubber scraper 15 is in close contact with the inner end of the transparent glass 7, guaranteeing the cleaning effect of the rubber scraper 15 on the transparent glass 7. This allows the operator to clearly observe the working conditions inside the fluidized bed granulator 1 through the observation window 2, promptly and accurately grasp the equipment's operating status and granulation quality, and effectively improve the control precision of the production process and product quality.
[0020] Specifically, two support legs 5 are symmetrically fixedly installed on the fluidized bed granulator 1. The observation window 2 consists of a round tube 6 and a transparent glass 7. The round tube 6 is fixedly inserted into the fluidized bed granulator 1, and the transparent glass 7 is fixedly installed on the inner wall of the round tube 6. A through hole 8 is opened at the axis of the transparent glass 7. When using the fluidized bed granulator 1 to granulate perfluorosulfonic acid resin powder, the perfluorosulfonic acid resin powder is first put into the fluidized bed granulator 1. The powder is fluidized in the bed by hot air flow. At the same time, a binder is sprayed in to make the powder particles agglomerate to form the required particles. The internal situation can be observed through the observation window 2 during the granulation process.
[0021] Specifically, the rotating ring 9 on the rotating limiting assembly 3 is rotatably sleeved on the outside of the round tube 6, the connecting rod 11 is located at the outer end of the round tube 6, the base shaft 14 on the cleaning assembly 4 is rotatably installed in the through hole 8 opened in the transparent glass 7, the base shaft 14 passes through the collar 10 at the same time, and two guide rail slots 17 are symmetrically opened on the outer wall of the base shaft 14. The base shaft 14 is movably sleeved on the protrusion 12 through the guide rail slots 17, the rubber scraper 15 is in close contact with the inner end of the transparent glass 7, and the rubber scraper 15 is fixedly connected to the base shaft 14 by screws. The anti-detachment baffle 16 is located outside the spring 13. When the inner end of the transparent glass 7 is attached When debris is removed, the rotating ring 9 of the rotating limit assembly 3 is rotated. The rotating ring 9 and the collar 10 are fixedly connected by the connecting rod 11. Rotating the rotating ring 9 drives the collar 10 to rotate synchronously. The symmetrically fixed protrusions 12 on the inner wall of the collar 10 drive the base shaft 14 to rotate through the guide rail groove 17 on the outer wall of the base shaft 14. The rubber scraper 15 fixedly embedded in the inner end of the base shaft 14 scrapes and cleans the inner surface of the transparent glass 7. The spring 13 fixed in the outer end of the collar 10 keeps the rubber scraper 15 in close contact with the inner end of the transparent glass 7 to ensure the cleaning effect, so that the operator can clearly observe the internal condition of the fluidized bed granulator 1 through the transparent glass 7.
