Description

Technical Field

[0001] The utility model relates to the technical field of the preparation of frame sealants, and particularly to a preparation device for a ketoxime - type two - component photovoltaic module frame sealant. Background Technique

[0002] The ketoxime - type two - component photovoltaic module frame sealant is a silicone - based material specially used for bonding and sealing the frames of photovoltaic modules. This sealant consists of two components, namely component A containing α,ω - dihydroxypolydimethylsiloxane and component B. Component A also contains reinforcing fillers, coupling agents, cross - linking agents, catalysts, etc., while component B mainly contains α,ω - dihydroxypolydimethylsiloxane and reinforcing fillers. This sealant can quickly cure after mixing to form a three - dimensional network elastic silicone rubber with excellent weather resistance, high and low temperature resistance, moisture resistance, and electrical insulation, which is suitable for long - term outdoor use of photovoltaic modules. And a preparation device is required in the production of frame sealants.

[0003] Common preparation devices for frame sealants include premixing tanks, intermediate tanks, rough mixing tanks, screw extruders, filling machines, and packaging machines. In the process of preparing the ketoxime - type two - component photovoltaic module frame sealant, stirring is a crucial step, which directly affects the quality and performance of the final product. Therefore, it is very important to stir the raw materials in the premixing tank and the rough mixing tank. During stirring, the rotation of the stirring blades is driven by an electric motor to mix the raw materials inside the tank.

[0004] However, in this way, since the electric motor can only drive the stirring blades to rotate circumferentially, it is impossible to effectively break the agglomeration between the materials. Especially for a material system with high viscosity such as sealant, vortices may be formed in the stirring container, resulting in the aggregation of materials in the center of the container and less contact of the edge materials with the stirring blades, thus forming dead corners and affecting the uniformity of mixing, which cannot meet the working requirements for the preparation of frame sealants. Therefore, a preparation device for a ketoxime - type two - component photovoltaic module frame sealant is proposed. Content of the Utility Model

When preparing the sealant, the raw material ratio includes: Component A: 40 - 60 parts of α,ω-dihydroxypolydimethylsiloxane, 40 - 60 parts of nano calcium carbonate, 5 - 10 parts of hydroxy silicone oil; Component B: 40 - 60 parts of α,ω-dihydroxypolydimethylsiloxane, 40 - 50 parts of nano calcium carbonate, 3 - 10 parts of crosslinking agent, 0.2 - 2 parts of catalyst. The mixing ratio of A:B is 1:1 (volume ratio or weight ratio). At the same time, for the preparation of Component A: The compound nano calcium carbonate filler is selected and added to Component A, which can not only improve the construction performance of Component A, but also ensure the tensile strength and good adhesion performance of the sealant.

After the configuration is completed, various raw materials are added into the mixing tank 1 through the material pipe. The first motor is started, and the rotation of the second gear 7 is driven by the first motor 6, so that the rotation of the output shaft 3 can be driven by the first gear 5, and the planet carrier 8 drives the scraping plates 14 and the stirring blades 15 to rotate, so as to mix and stir the sealant raw materials inside the mixing tank 1.

The outer parts of the assembly rods 19 are sleeved with springs 22 on both the upper and lower sides, and the inner ends of the springs 22 are connected to the corresponding positions of the double-headed motors 20. On both the left and right sides of the double-headed motors 20, there are reinforcing ribs 23 welded, and the inner sides of the reinforcing ribs 23 are connected to the corresponding positions on the upper surface of the supporting plate 4. The rotation of the cam 21 can be driven by the double-headed motor 20, so that the double-headed motor 20 can vibrate up and down with the cooperation of the spring 22, and then the supporting plate 4 can be driven to vibrate up and down, so that when the scraping plate 14 and the stirring blades 15 rotate, they vibrate synchronously, which helps to promote the convection and diffusion of the materials inside the mixing tank 1, so as to achieve faster and more uniform mixing. This movement mode can reduce the stirring dead angle. At the same time, the stirring blades 15 moving up and down can apply a stronger shear force to the materials, which helps to disperse solid particles or droplets and make them evenly dispersed in the sealant matrix.

[0036] In this solution, the rotation of the second gear 7 is driven by the first motor 6, so that the rotation of the output shaft 3 can be driven by the first gear 5, and the planet carrier 8 drives the scraping plate 14 and the stirring blades 15 to rotate to mix and stir the sealant raw materials inside the mixing tank 1.

Under the restriction of the arc-shaped groove 12 inside the tooth disc 9, the outward expansion of the plug shaft 16 and the plug plate 13 can be synchronously driven, so that the scraping plate 14 and the stirring blades 15 can continuously move towards the inner wall of the mixing tank 1 until they fit. The contact between the scraping plate 14 and the inner wall can help to bring the materials adhering to the container wall back into the stirring area, ensure that all materials can be fully mixed, avoid the formation of unreacted dead angles. At the same time, since the stirring radius of the stirring blades 15 can be adjusted, the formation of vortices in the stirring container is prevented, and the aggregation of materials in the center of the container is avoided. And because the sealant materials will deposit on the container wall, the contact scraping of the scraping plate 14 can prevent this deposition and maintain the uniformity of the materials in the stirring container. And the scraping plate 14 contacting the inner wall can remove the residual materials on the inner wall of the container, which is convenient for cleaning and maintenance, ensuring the continuity of the production process and the consistency of the products. At the same time, the rotation of the cam 21 can be driven by the double-headed motor 20, so that the double-headed motor 20 can vibrate up and down with the cooperation of the spring 22, and then the supporting plate 4 can be driven to vibrate up and down, so that when the scraping plate 14 and the stirring blades 15 rotate, they vibrate synchronously, which helps to promote the convection and diffusion of the materials inside the mixing tank 1, so as to achieve faster and more uniform mixing. This movement mode can reduce the stirring dead angle.
