Description

Technical Field

[0001] This invention relates to the field of photovoltaic glass manufacturing technology, and more specifically, to a tempering device for photovoltaic glass. Background Technology

[0002] Photovoltaic glass, also known as "photovoltaic glass", is a special type of glass that generates electricity using solar radiation and has related current extraction devices and cables. Photovoltaic glass consists of glass, solar cells, film, back glass, special metal wires, etc. In the production process of photovoltaic glass, a tempering furnace is required to temper the glass.

[0003] A search revealed that patent CN211896660U discloses a glass tempering furnace for processing tempered glass, including a feeding device and a furnace body. The furnace body contains a conveying device, which includes a conveying frame and several conveying rollers rotatably connected to the frame. The conveying rollers are equidistantly arranged along the length of the frame. Two sets of limiting shafts are provided on the conveying frame between adjacent conveying rollers to prevent the glass from detaching from the frame. Limiting sleeves are rotatably connected to the limiting shafts. This invention effectively prevents the glass from being damaged by contacting the furnace body during conveying.

[0004] Regarding the aforementioned technologies, existing tempering furnaces are typically in the above-described state. Current tempering furnaces first heat the tempered glass and then cool it. In existing technologies, tempering furnace cooling is usually achieved through air cooling, which is divided into ordinary air cooling and air cooling with refrigeration. While ordinary air cooling can achieve cooling, the cooling effect is relatively slow. Air cooling with refrigeration, compared to ordinary air cooling, usually requires the addition of a refrigeration unit, such as a compressor, condenser, evaporator, and expansion valve. The procurement cost of these refrigeration components is high, increasing the equipment cost by tens of thousands of yuan. Excessive cost hinders the widespread use of the equipment. Therefore, there is a need for a lower-cost, more readily available cooling method with good cooling effect. To this end, a tempering device for photovoltaic glass is proposed.

At the same time, compared with the compressor, condenser, evaporator, expansion valve and other components in the prior art, this equipment has significantly reduced costs, making it easier for the equipment to be widely used. (2) By setting up the connecting pipe, air guide and heat sink, the present invention can dissipate the heat generated by the heating surface when the semiconductor refrigeration chip is working, avoid the semiconductor refrigeration chip from overheating, and thus allow the semiconductor refrigeration chip to work stably, ensuring the stability of the semiconductor refrigeration chip during operation. (3) The present invention uses a movable rod, a pusher blade, a small transmission roller, a large transmission roller and a transmission belt to make the pusher blade push the coolant to flow inside the coolant tank, thereby making the coolant temperature more uniform and avoiding a large temperature difference in the coolant inside the coolant tank due to the length of air flow inside the spiral heat pipe, so that the coolant can be more uniform and thus improve the uniformity of tempered glass cooling.

[0021] The following is in conjunction with the appendix Figure 1-8 The present invention will be described in further detail below.

[0022] Please see Figure 1-8A tempering device for photovoltaic glass includes a main module 100 and two cooling modules 200. The main module 100 includes a conveying device 110, and a tempering furnace body 120 is mounted on top of the conveying device 110. Both cooling modules 200 are mounted on the conveying device 110 and connected to the tempering furnace body 120. The two cooling modules 200 are symmetrically arranged. Each cooling module 200 includes a cooling box 210 fixedly connected to the conveying device 110, with its front end connected to the tempering furnace body 120. An inner frame 220 is fixedly connected between the two sides of the inner wall of the box 210. An air outlet component 230 is installed inside the inner frame 220. A heat conduction component 240 is installed on the outer surface of the inner frame 220. A cooling component 250 connected to the air outlet component 230 is installed on the inner wall of the inner frame 220. The cooling component 250 is connected to the heat conduction component 240.

A perforated air distribution plate 270 is fixedly connected to the inner wall of the cooling box 210. The perforated air distribution plate 270 is close to the conveying device 110.

[0023] In use, the tempered glass to be heated is placed on the conveying device 110 and transported to the interior of the tempering furnace body 120 for heating. After heating, the tempered glass is sent between two cooling modules 200. When the cooling modules 200 are working, the air outlet component 230 will be opened to blow air onto the tempered glass. At the same time, the cooling component 250 will be opened, and the air outlet component 230 will drive the cooling component 250 to cool the heat conduction component 240. The heat conduction component 240 will uniformly cool the air blown out by the air outlet component 230, thereby achieving rapid cooling of the tempered glass. The symmetrical arrangement of the two cooling modules 200 can achieve double-sided heat dissipation of the tempered glass. After cooling, the tempered glass will be sent out between the two cooling modules 200.

[0024] The heat-conducting assembly 240 includes four mounting brackets 241 fixedly connected to both sides of the inner hollow frame 220. A coolant tank 242 is fixedly connected between the interiors of every two mounting brackets 241. A spiral heat-conducting tube 244 is fixedly connected to the inner wall of each of the two coolant tanks 242, with both ends of the spiral heat-conducting tube 244 extending into the interior of the inner hollow frame 220. Multiple connecting pipes 243 are fixedly connected between the upper parts of the outer surfaces of the two coolant tanks 242. The heat-conducting assembly 240 also includes multiple heat-conducting capillary tubes 247 fixedly connected between the interiors of the two coolant tanks 242. All 7 tubes penetrate the inner hollow frame 220. A connecting pipe 246 is fixedly connected to one end of each of the multiple heat-conducting thin tubes 247. A liquid pump 245 is installed on the inner wall of one of the coolant tanks 242. The output end of the liquid pump 245 is connected to one end of the connecting pipe 246. The air outlet assembly 230 includes multiple mounting plates 231 fixedly connected inside the inner hollow frame 220. A first inner rotating rod 232 is rotatably connected inside each of the mounting plates 231. A first fan blade 233 is fixedly connected to the bottom end of each of the first inner rotating rods 232, and a first small conical tooth 2 is fixedly connected to the top end of each of the first inner rotating rods 232. 34. The air outlet assembly 230 also includes a long rod 235 rotatably connected between the two sides of the inner wall of the conveying device 110. One end of the long rod 235 extends to the outside of the refrigeration box 210. A drive motor 237 is fixedly connected to one side of the refrigeration box 210. The output shaft of the drive motor 237 is fixedly connected to one end of the long rod 235. Multiple large conical teeth 236 are fixedly connected to the outer surface of the long rod 235. The multiple large conical teeth 236 respectively mesh with multiple first small conical teeth 234. The refrigeration assembly 250 also includes a refrigeration cone 251 fixedly connected to the inner wall of the inner hollow frame 220. The inner wall of the refrigeration cone 251... A second inner rotating rod 252 is rotatably connected to the bottom. A second small conical tooth 253 is fixedly connected to the bottom end of the second inner rotating rod 252. The outer surface of the second small conical tooth 253 meshes with one of the large conical teeth 236. A second fan blade 254 is fixedly connected to the top end of the second inner rotating rod 252. The second fan blade 254 is located inside the cooling cone 251. Three mounting slots are opened on the outer surface of the cooling cone 251. The three mounting slots are arranged in a triangle. Semiconductor cooling chips 255 are fixedly connected inside the three mounting slots. The outer surface of the cooling cone 251 is connected to one end of two spiral heat pipes 244.

[0025] The tempered glass to be heated is placed on the conveyor 110 and transported to the interior of the tempering furnace body 120 for heating. After heating, the tempered glass is sent between two cooling modules 200. When the cooling modules 200 are working, the drive motor 237 is turned on, which drives the long rod 235 to rotate. When the long rod 235 rotates, it drives multiple large conical teeth 236 to rotate. The multiple large conical teeth 236 drive the first inner rotating rod 232 and the first fan blade 233 to rotate through the first small conical teeth 234. The multiple first fan blades 233 blow out cooling air, which is blown through multiple heat-conducting thin tubes 247 to the porous air distribution plate 270. The porous air distribution plate 270 makes the cooling air blow more evenly onto the tempered glass. At this time, the semiconductor cooling chip 255 is turned on for cooling. One of the large conical teeth 236 During rotation, the second inner rotating rod 252 is driven by the second small bevel tooth 253. The second inner rotating rod 252 drives the second fan blade 254 to rotate, and the second fan blade 254 blows air. The blown air is cooled by the semiconductor cooling chip 255 and then enters two spiral heat conduction pipes 244. The two spiral heat conduction pipes 244 conduct heat to the air temperature, thereby cooling the coolant inside the coolant tank 242. At this time, the liquid pump 245 is turned on, and the liquid pump 245 draws the coolant from one of the coolant tanks 242 and delivers it into the connecting pipe 246. The coolant then enters the other coolant tank 242 through multiple heat conduction thin tubes 247. The multiple heat conduction thin tubes 247 cool the air blown out by the first fan blade 233, thereby achieving cooling air cooling for tempered glass. This method is low-cost and easy to popularize.

[0026] The cooling assembly 250 also includes an air guide shroud 256 fixedly connected to the outer surface of the cooling cone 251. The heating surfaces of the three semiconductor cooling chips 255 are each fixedly connected to multiple heat sinks, which are located inside the air guide shroud 256. Two connecting pipes 257 are fixedly connected to the outer surface of the air guide shroud 256. One end of the two connecting pipes 257 is fixedly connected to the other end of the two spiral heat pipes 244 respectively.

[0027] The cool air flowing inside the spiral heat pipe 244 will then enter the interior of the connecting pipe 257, and subsequently enter the air guide shroud 256 through the connecting pipe 257, thereby dissipating heat from the heating surface of the semiconductor cooling chip 255. In conjunction with multiple heat sinks, this achieves a better heat dissipation effect.

[0028] Two flow components 260 are respectively disposed inside two coolant tanks 242. The flow component 260 includes a movable rod 261 rotatably connected inside one of the coolant tanks 242. One end of the movable rod 261 extends to the outside of the refrigeration box 210. Multiple pusher blades 262 are fixedly connected to the outer surface of the movable rod 261. The flow component 260 also includes a small transmission roller 263 fixedly connected to one end of the movable rod 261. A large transmission roller 264 is fixedly connected to the outer surface of the output shaft of the drive motor 237. A transmission belt 265 is connected between the outer surfaces of the large transmission roller 264 and the small transmission roller 263. The cooling module 200 also includes an air inlet slot opened on the top of the refrigeration box 210. A filter screen 280 is provided on the top of the refrigeration box 210. The filter screen 280 is located outside the air inlet slot. Multiple bolts are threadedly connected between the filter screen 280 and the top of the refrigeration box 210.

[0029] The large transmission roller 264 drives the transmission belt 265, which in turn drives the small transmission roller 263 to rotate the movable rod 261. The movable rod 261 then drives multiple pusher blades 262 to rotate, which in turn pushes the coolant to flow inside the coolant tank 242. This makes the coolant temperature more uniform and avoids large temperature differences in the coolant inside the coolant tank 242 due to the length of air flow inside the spiral heat pipe 244. The filter screen 280 also eliminates the need for dust prevention operations on the air inlet slot.

[0030] The implementation principle of this invention is as follows: During use, the tempered glass to be heated is placed on the conveying device 110 and transported to the interior of the tempering furnace body 120 for heating. After heating, the tempered glass is sent between two cooling modules 200. When the cooling modules 200 are working, the drive motor 237 is turned on, driving the long rod 235 to rotate. The rotation of the long rod 235 drives multiple large conical teeth 236 to rotate. These large conical teeth 236, through the first small conical teeth 234, drive the first inner rotating rod 232 and the first fan blade 233 to rotate. The multiple first fan blades 233 blow out cooling air, which is then blown through multiple heat-conducting thin tubes 247 towards… The perforated air distribution plate 270 ensures that the cooling air is blown more evenly onto the tempered glass. At this time, the semiconductor cooling chip 255 is activated for cooling. When one of the large conical teeth 236 rotates, it drives the second inner rotating rod 252 via the second small conical tooth 253. The second inner rotating rod 252 then drives the second fan blade 254 to rotate, causing it to blow air. The blown air is cooled by the semiconductor cooling chip 255 and then enters two spiral heat pipes 244. The two spiral heat pipes 244 conduct heat to the air, thereby cooling the coolant inside the coolant tank 242. At this time, the liquid pump 245 is activated, drawing coolant from one of the coolant tanks 242 to connect to the cooling system. The coolant is transported inside pipe 246, and subsequently enters another coolant tank 242 through multiple heat-conducting capillary tubes 247. These capillary tubes 247 cool the air blown out by the first fan blade 233, thus achieving cooling airflow for the tempered glass. This method is low-cost and easy to widely adopt. The other coolant tank 242 pre-cools the coolant through a spiral heat-conducting pipe 244, and the connecting pipe 243 connects the two coolant tanks 242, allowing the pre-cooled coolant in the other tank 242 to return to its interior for further cooling. The heat-conducting cold air flowing inside the spiral heat-conducting pipe 244 subsequently enters the connecting pipe 257, and then... Connecting pipe 257 enters air guide shroud 256, thereby dissipating heat from the heating surface of semiconductor cooling chip 255. Combined with multiple heat sinks, this achieves better heat dissipation. When drive motor 237 is operating, it drives transmission belt 265 via large transmission roller 264. Transmission belt 265 drives small transmission roller 263, causing movable rod 261 to rotate. Movable rod 261 drives multiple propulsion blades 262 to rotate. Propulsion blades 262 push the coolant to flow inside coolant tank 242, resulting in a more uniform coolant temperature. This avoids large temperature differences in the coolant inside coolant tank 242 due to the limited airflow length inside spiral heat pipe 244, thus ensuring uniform cooling of the air blown out by first fan blade 233.The symmetrical arrangement of the two cooling modules 200 enables double-sided heat dissipation from the tempered glass. Once cooled, the tempered glass is then conveyed between the two cooling modules 200.

[0031] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
