Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic adhesive films, and specifically relates to a condensed water collecting and recycling device for a cooling roller. Background Art

[0002] Photovoltaic film is a commonly used encapsulation film for solar cell modules. It can not only play the role of encapsulation and bonding in the module, but also has various functions such as insulation, light transmission, light blocking, and protection. In the production process of photovoltaic film, there are often multiple cooling rollers in the production line. Some cooling rollers need to pass through coolant with a temperature of 0 to 15°C according to the production process. The surface of the inlet and outlet pipes will be cooled and frozen, and then melted and dripped at ambient temperature. Condensed water.

[0003] If not treated, condensed water will wet some equipment and the ground. The slippery ground will seriously affect operational safety. Once the equipment is wet, the condensed water will accelerate the corrosion and oxidation of the material, affecting the service life of the production equipment and increasing maintenance costs.

[0022] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0023] like Figures 1 to 4 As shown, the condensate collection and recovery device of the cooling roller comprises a bracket 1, a cooling roller 2 is arranged on the bracket 1, one end of the cooling roller 2 is connected to a coolant inlet pipe 3, and a first collecting tank 4 is arranged on the bracket 1, and the first collecting tank 4 is located below one end of the coolant inlet pipe 3. By arranging the collecting tank below the coolant inlet pipe 3, the melted condensate is collected to avoid wetting the equipment or the ground.

[0024] like Figure 1 As shown, a heat-insulating layer 6 is provided outside the coolant inlet pipe 3. The heat-insulating layer 6 is used to cover the pipe portion without a joint and a rotating shaft on the coolant inlet pipe 3, thereby reducing energy consumption and preventing the pipe surface from directly contacting the air and freezing, thereby preventing the ice from melting to form condensed water. The heat-insulating layer 6 is selected to be a rubber-plastic sponge, rock wool, hard polyurethane foam or a silicate composite material. Similarly, a heat-insulating layer 6 can also be installed on the coolant outlet pipe or a collection tank can be set below it.

[0025] like Figure 1 and Figure 2 As shown, a second collecting tank 5 is provided below the cooling roller 2, and the first collecting tank 4 and the second collecting tank 5 are respectively located on both sides of the bracket 1. The second collecting tank 5 is at the same height as the first collecting tank 4, and the second collecting tank 5 is connected to the first collecting tank 4 by bolts 11. A collecting tank is also provided below the cooling roller 2 to collect the condensed water melted on the cooling roller 2. The two collecting tanks can be used in combination to collect and recycle the condensed water on the cooling roller 2 and the coolant inlet pipe 3, respectively, to improve the collection efficiency of the condensed water; and the two collecting tanks are at the same height, which can make full use of the installation space on the bracket 1 and reduce the number of connectors, thereby facilitating the direct modification and installation of the existing equipment. The main material of the collecting tank is 304 stainless steel or 316 stainless steel, and the size is determined according to the actual size of the rotating shaft. Bolts 11 are used to fix the bracket 1 and are located below the thermal insulation layer 6.

[0026] like Figures 2 to 4 As shown, the bottom of the first collecting tank 4 and the second collecting tank 5 are both connected to a reflux pipe 7. The leakage at the bottom of the collecting tank is connected to the reflux pipe 7 and leads to the main engine water tank for water replenishment, so as to realize the recycling and reuse of condensed water.

[0027] like Figure 3 and Figure 4As shown, a valve 8 is provided on the return pipe 7, and a thread 9 is provided at the bottom of the return pipe 7. The return pipe 7 can be opened or closed at any time by using the valve 8. When the equipment is not in use, the return pipe 7 can be closed in time to avoid blockage of the return pipe 7 caused by external environmental factors; the thread 9 at the bottom of the return pipe 7 can be installed with other pipes to facilitate the drainage of condensed water to the main machine water tank.

[0028] like Figure 1 As shown, mounting holes 10 are evenly distributed on the bracket 1. The bracket 1 provides a mounting position for the arrangement of two collection tanks. The mounting holes 10 are used to cooperate with the bolts 11. Multiple mounting holes 10 can easily change the installation height of the collection tank, so that the collection tank can be installed at a suitable height, reducing the splashing effect of the falling condensed water, and further reducing the impact of surrounding components and the ground.

[0029] like Figure 1 As shown, the second collecting trough 5 is adapted to the length of the cooling roller 2. The above structure allows the collecting trough to completely receive the condensed water falling from various positions on the cooling roller 2, which can fully reduce the probability of the condensed water wetting the equipment or the ground.

[0030] like Figure 2 As shown, the first collecting tank 4 and the second collecting tank 5 are both square tank structures. The collecting tank with a square structure has a large contact area with the bracket 1, high stability, and is easy to manufacture by stainless steel welding. At the same time, it can also accommodate a certain amount of condensed water to avoid overflow.

[0031] The condensate collection and recovery device of the cooling roller adopts two different methods, namely, insulation and collection, to deal with the condensate problem, thereby realizing the recovery of condensate into the cooling water tank for reuse, achieving the effect of stable, clean and sustainable development, reducing equipment maintenance costs, and ensuring the service life of production equipment. It provides a solution for the condensate treatment of cooling rollers 2 in the field of photovoltaic films.

[0032] The condensed water collection and recovery device of the cooling roller uses the insulation layer 6 to cover the pipeline, avoiding the problem of condensation and ice on the surface of the pipeline. Combined with the collection of condensed water by the collection tank, the collected condensed water can be recycled and replenished in the water tank for use as circulating water, avoiding the problem of production equipment damage and on-site production safety caused by condensed water, not only reducing the equipment maintenance cost, but also ensuring the service life of the production equipment. The device has a simple structure, is easy to install, has a low application cost, can be directly installed in the existing equipment, and will not affect the operation of the equipment.

[0033] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
