Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, specifically a lightweight photovoltaic backsheet adhesive reaction vessel. Background Technology

[0002] Solar photovoltaic module sealant is a neutral silicone sealant that cures at room temperature by absorbing moisture from the air. It is specifically designed for bonding and sealing solar photovoltaic modules. Representative models include...

[0003] 385W is suitable for sealing components such as backsheets, aluminum alloy frames, and junction boxes. It is environmentally friendly, non-corrosive, aging-resistant, resistant to thermal cycling, and has excellent electrical properties. The preparation process of photovoltaic backsheet adhesive requires the use of a reaction vessel to mix and process various raw materials.

[0004] In a Chinese patent (patent number: CN119286323A) for a photovoltaic backsheet film EB curing coating and its preparation and application methods, the apparatus includes the following steps: adding 44.5% polycarbonate acrylic resin, 25% aliphatic polyurethane acrylic resin, 15% multifunctional active monomer, 15% monofunctional active monomer, 0.3% leveling agent, and 0.2% defoamer to a reaction vessel, ensuring the reaction vessel is sealed and dust-free, and maintaining its internal vacuum between -0.1 MPa and -1 MPa, for mixing. The mixture is stirred for 20-40 minutes and then allowed to stand and cool for more than 30 minutes to obtain the EB-cured coating. The EB-cured coating is then applied to the photovoltaic PET film. The process involves EB curing, inspection, recoating of unqualified films, and further processing to obtain the photovoltaic backsheet film. However, the existing reactors for lightweight photovoltaic backsheet adhesives have overly simple structures, using only a single horizontal rotation to stir the backsheet adhesive raw materials. This results in poor stirring effect and low efficiency, thus affecting the preparation effect of lightweight photovoltaic backsheet adhesives. Utility Model Content

[0021] Please see Figures 1-4 This embodiment provides a reaction vessel for lightweight photovoltaic backsheet adhesive. The lightweight photovoltaic backsheet adhesive is a prior art material, and various raw materials can be found in the background art documents. It includes a vessel body 1. The upper side wall of the vessel body 1 is respectively connected to a feed valve port 2, a vacuum valve connector 3, and a pressure gauge 4. The bottom of the vessel body 1 is connected to a discharge valve pipe 5. The feed valve port 2 is used to add raw materials. The vacuum valve connector 3 is connected to a vacuum pump. The pressure gauge 4 monitors the air pressure inside the vessel body 1 to ensure the sealing and vacuum of the vessel body 1. Each valve port is equipped with a solenoid valve. A cover 6 is fixedly connected to the top of the vessel body 1. A lifting and stirring mechanism is provided in the vessel body 1 and the cover 6.

[0022] The lifting and stirring mechanism includes a stirring motor 7 fixed to the upper side wall of the casing 6. The main shaft of the stirring motor 7 extends through the casing 6 and is fixedly connected to a rectangular limiting post 8. A sliding hole is provided on the upper side wall of the vessel body 1 located in the casing 6. A vertically arranged stirring rod 9 is slidably connected in the sliding hole. A rectangular limiting groove 10 is provided at the upper end of the stirring rod 9. The lower end of the rectangular limiting post 8 is inserted into the rectangular limiting groove 10 and slidably connected to it. A reciprocating lifting mechanism is provided in the casing 6. One end of the reciprocating lifting mechanism is connected to the stirring rod 9. The stirring rod 9 extends into the vessel body 1 and is fixedly connected to a stirring blade 11. When the stirring motor 7 is started, it can drive the rectangular limiting post 8 to rotate. Utilizing the rectangular characteristic of the rectangular limiting groove 10, it can drive the stirring rod 9 to rotate, thereby driving the stirring blade 11 to rotate. This can stir and react the lightweight photovoltaic backsheet adhesive raw material in the vessel body 1. At the same time, in conjunction with the reciprocating lifting mechanism, the stirring blade 11 can reciprocate and lift in the vessel body 1 while rotating, thereby improving the stirring range and stirring effect.

[0023] like Figure 3 and Figure 4 As shown: The reciprocating lifting mechanism includes a servo motor 12 fixed on one side of the housing 6. A cam 13 is fixedly connected to the inner end of the main shaft of the servo motor 12. A pull block 14 is movably connected to the end of the cam 13 away from its rotation center. A circular sleeve 15 is rotatably connected to the outer wall of the upper end of the stirring rod 9 through a bearing component. The end of the pull block 14 away from the cam 13 is movably connected to the outer wall of the circular sleeve 15. When the servo motor 12 is started to rotate, it can drive the cam 13 to rotate, thereby pulling the pull block 14 to swing displacement. At this time, it can drive the stirring rod 9 connected to the circular sleeve 15 to reciprocate lifting displacement, thereby driving the stirring blade 11 to reciprocate lifting displacement in the vessel body 1, improving the stirring range and stirring effect, thereby improving the stirring effect of lightweight photovoltaic backsheet adhesive.

[0024] like Figure 3 As shown: the outer wall of the stirring rod 9 is welded and fixedly connected to the inner wall of the bearing component, and the inner wall of the circular sleeve 15 is welded and fixedly connected to the outer wall of the bearing component, ensuring that the stirring rod 9 moves up and down with the circular sleeve 15, and the stirring rod 9 can rotate inside the circular sleeve 15.

[0025] like Figure 3 As shown: A support frame 20 is fixedly connected to the inner bottom wall of the vessel body 1. A vertically arranged stirring shaft 21 is rotatably connected to the support frame 20 through a bearing seat. A rectangular guide post 22 is fixedly connected to the upper end of the stirring shaft 21. A rectangular guide groove 23 is opened at the lower end of the stirring rod 9. The upper end of the rectangular guide post 22 is inserted into the rectangular guide groove 23 and slidably connected to it, so that the rectangular guide groove 23 on the stirring rod 9 can move up and down along the rectangular guide post 22 to play a guiding role. Moreover, taking advantage of the characteristics of rectangle, when the rectangular guide groove 23 rotates, it can drive the stirring shaft 21 fixed to the rectangular guide post 22 to rotate.

[0026] like Figure 2 As shown: Two symmetrically arranged mounting brackets 17 are fixedly connected to both sides of the stirring shaft 21. Scraper strips 18 are fixedly connected to the far ends of the two mounting brackets 17. The scraper strips 18 are set against the inner bottom wall of the reactor body 1, which can stir the photovoltaic backsheet adhesive raw material at the bottom of the reactor body 1 and avoid the existence of stirring dead corners.

[0027] like Figure 1 As shown: A control panel 19 is fixedly connected to the front side wall of the vessel body 1. The control panel 19 is electrically connected to the feed valve port 2, the vacuum valve connector 3, the discharge valve pipe 5, and the lifting and stirring mechanism. It is easy to operate and has an external power supply. The circuit involved is existing technology and can be fully implemented by those skilled in the art, so there is no need to elaborate.

[0028] like Figure 3 As shown: A sealing ring 16 is fixedly connected to the inner wall of the sliding hole. The inner wall of the sealing ring 16 is slidably connected to the outer wall of the stirring rod 9 to prevent the raw material of the photovoltaic backsheet adhesive from entering the cover 6, and without affecting the lifting displacement and rotation of the stirring rod 9.

[0029] Working principle: When this device is used to process lightweight photovoltaic backsheet adhesive raw materials through stirring and reaction, starting the stirring motor 7 will drive the rectangular limiting column 8 to rotate. Utilizing the rectangular characteristic of the rectangular limiting groove 10, the stirring rod 9 will rotate, thereby driving the stirring blade 11 to rotate. This will stir and react the lightweight photovoltaic backsheet adhesive raw materials in the reactor body 1. Simultaneously, starting the servo motor 12 will drive the cam 13 to rotate, which in turn will pull the pull block 14 to swing and displace. At this time, the stirring rod 9, connected to the circular sleeve 15, will reciprocate up and down. This causes the stirring blades 11 to reciprocate up and down within the vessel 1, increasing the stirring range and agitation effect, thereby improving the stirring effect on the lightweight photovoltaic backsheet adhesive. Simultaneously, the rectangular guide groove 23 on the stirring rod 9 can move up and down along the rectangular guide post 22, serving as a guide. Utilizing the characteristics of a rectangle, when the rectangular guide groove 23 rotates, it can drive the stirring shaft 21, which is fixed to the rectangular guide post 22, to rotate, thereby driving the scraper strip 18 to rotate. This allows for stirring of the photovoltaic backsheet adhesive raw material at the bottom of the vessel 1, avoiding any dead zones in the stirring process.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
