Description

Technical Field

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

[0002] Photovoltaic glass, as the specialized glass for solar cell cover plates, plays a crucial role. It not only protects the solar panels from oxidation and corrosion caused by external moisture and gases but also ensures the modules are not damaged by external forces. The core performance characteristics of photovoltaic glass lie in its high light transmittance, high strength, and strong corrosion resistance; these properties directly affect the lifespan and power generation efficiency of photovoltaic modules. Whether used as a front or back cover plate, photovoltaic glass requires a certain level of strength. Therefore, in the research and development of photovoltaic glass or other types of glass, tempering experiments must first be conducted in the laboratory to verify its tempering performance.

[0003] Glass tempering comes in two forms: physical tempering and chemical tempering. Chemical tempering involves ion exchange in a molten salt bath. For example, Chinese patent 202120244952.3 discloses a glass tempering furnace with a flowing bath salt, which tempers glass through molten salt ion exchange. However, it requires a large amount of salt, making it unsuitable for small-batch experimental glass tempering. With technological advancements and process development, some glasses now require two or more tempering processes with different types of molten salts to achieve target performance. Therefore, in laboratory glass product verification, where the quantity of glass is small and the product types are diverse, frequent changes of the molten salt in the tempering furnace are necessary. Since salt changes in the tempering furnace are performed at high temperatures, the process is difficult, time-consuming, and costly, severely impacting the efficiency of tempering experiments. Utility Model Content

The base plate and the anti-overflow uprights form a suspension cavity with an open top.

[0010] In some embodiments, a set of opposite anti-overflow plates of the suspended frame are provided with connecting lugs, and the hoisting mechanism is connected to the tempered glass box through the connecting lugs.

[0035] Figures 1 to 7 An embodiment of the glass tempering device of this application is illustrated schematically.

[0036] like Figures 1 to 7 As shown, this application discloses a glass tempering device, which includes a tempering furnace 1, a tempering box 2, and a hoisting mechanism (not shown). The tempering furnace 1 has a hollow structure with an open top to form a molten salt bath space. The hoisting mechanism connects to the tempering box 2 and hoists it into the tempering furnace 1. The tempering box 2 includes a tempering tank 21 and a suspension frame 22. Salt for ion exchange is placed inside the tempering tank 21. The suspension frame 22 is connected above the tempering tank 21 and extends outwards and upwards to form a suspension cavity, allowing the tempering box 2 to suspend on the surface of the molten salt in the tempering furnace 1.

[0037] Through the above structural design, the glass tempering equipment of this application embodiment can achieve independent tempering of small batches of glass within a large tempering furnace 1 by hoisting the tempering box 2, without the need to replace the salt material in the entire tempering furnace 1. This greatly reduces the difficulty and time cost of salt replacement, while also saving salt material. Furthermore, the tempering box 2 is equipped with a suspension frame 22. The suspension frame 22 can prevent the salt material in the tempering box 2 from flowing into the tempering furnace 1, causing contamination of the mass production salt material, and can also increase the contact area between the tempering box 2 and the tempering furnace 1, allowing the tempering box 2 to float on the surface of the molten salt in the tempering furnace 1 during the tempering experiment, preventing it from sinking to the bottom of the furnace, facilitating hoisting and removal. Therefore, this application can effectively reduce the cost and time cost of tempering salt material before mass production tempering. Its structure is simple, low-cost, and easy to use.

[0038] In some embodiments of this application, such as Figures 2 to 4As shown, the tempering tank 21 is a square groove, and the suspension frame 22 is a square extended frame. The tempering tank 21 and the suspension frame 22 are concentrically arranged to ensure a symmetrical and uniform structural layout. This design makes the suspension frame 22 more stable during suspension, preventing fluctuations in the brine within the tempering tank 21 that could cause overflow and spillage, thus reducing the risk of contaminating the mass-produced salt in the tempering furnace 1. Figures 2 to 4 As shown, the suspension frame 22 includes a horizontally arranged base plate 221 and anti-overflow upright plates 222 connected around the base plate 221. The base plate 221 and the anti-overflow upright plates 222 form a suspension cavity with an open top, so as to increase the contact area with the molten salt in the tempering furnace 1 and ensure sufficient drainage capacity so that the tempering box 2 is suspended on the surface of the molten salt liquid and does not sink to the bottom of the tempering furnace 1.

[0039] In some embodiments of this application, such as Figures 2 to 4 As shown, a set of opposite anti-overflow uprights 222 of the suspended frame 22 are provided with connecting lugs 223, and the hoisting mechanism is connected to the tempered glass box 2 through the connecting lugs 223. In some other embodiments of this application, connecting lugs 223 can also be provided on all four anti-overflow uprights 222 to achieve four-line traction hoisting, further increasing hoisting stability and avoiding skewing and spillage.

[0040] In some embodiments of this application, such as Figures 5 to 7 As shown, the glass tempering equipment of this application further includes: a glass carrier 3, the glass carrier 3 being adapted to the shape of the tempering tank 21 to be placed inside the tempering tank 21 to stabilize the glass 4 to be tempered (see...). Figure 5 (As shown). The hoisting mechanism can also be connected to the glass carrier 3 to hoist the glass carrier 3 into the tempered glass tank 21. Specifically, in this embodiment, connecting lugs are also provided at both ends of the glass carrier 3 to achieve hoisting connection.

[0041] In some embodiments of this application, multiple sets of tempering boxes 2 and glass carriers 3 are provided together. The tempering boxes 2 and glass carriers 3 have different sizes and shapes, such as different size specifications and cross-sectional shapes such as square or round. Multiple sets of tempering boxes 2 and glass carriers 3 are used to match glass 4 of different sizes to be tempered, so as to meet the needs of different batches of product production.

[0042] In some embodiments of this application, such as Figure 5 and Figure 6As shown, the glass carrier 3 of this application is a U-shaped carrier with open ends. Multiple partition slots 31 are provided within the U-shaped carrier, and multiple pieces of glass 4 to be tempered are placed in the partition slots 31 at intervals. By setting the partition slots 31 to place the glass 4 to be tempered at intervals, the overlapping of the glass 4 to be tempered during the tempering process can be avoided, ensuring the accuracy of the tempering experiment. In a preferred embodiment of this application, baffles are provided at both open ends of the glass carrier 3 to stabilize the position of the glass 4 to be tempered without affecting the entry of the salt solution for ion exchange, thus protecting the glass. Furthermore, in this embodiment, the partition slots 31 of the glass carrier 3 are implemented using multiple sets of partition blocks, with the entire structure vertical, so that no residual air bubbles remain when the salt solution contacts the glass 4 to be tempered, ensuring sufficient contact and ion exchange.

[0043] In some embodiments of this application, such as Figure 7 As shown, another glass carrier 3 in this application is also a U-shaped carrier with open ends. Multiple inclined support plates 32 are installed inside the U-shaped carrier. Multiple pieces of glass 4 to be tempered can be placed inclinedly on the support plates 32. This inclined placement method utilizes the weight of the glass to stabilize its position, overcoming the possibility of shaking and collision when the glass is placed upright, further protecting the glass (especially ultra-thin glass). Each support plate 32 has a stop bar 33 below it to prevent the glass from sliding. Each support plate 32 has a hollow structure, such as a mesh structure or a combination of multiple rods, to ensure support while minimizing the contact area, ensuring sufficient contact between the glass and the salt solution used for ion exchange, and ensuring experimental accuracy.

[0044] In some embodiments of this application, the tempering furnace 1 is equipped with salt quantity markings, which allows for quick determination of the salt quantity and ensures that the molten salt in the tempering box 2 does not overflow or cause waste during placement. Furthermore, an asbestos insulation layer is provided outside the tempering furnace 1 to effectively maintain a stable internal temperature and reduce heat loss and energy waste. Understandably, the tempering furnace 1 of this application is equipped with a heating device during production. This heating device can be built into the tempering furnace 1 or be an external device; this is conventional technology in the art and is not limited herein.

[0045] In some embodiments of this application, temperature sensors are installed in both the tempering furnace 1 and the tempering box 2, so that the temperature inside the tempering furnace 1 and the tempering box 2 can be monitored in a comprehensive manner and the tempering process can be controlled.

[0046] In some embodiments of this application, the tempering equipment, which is equipped with a tempering box 2, also includes an operating table. The operating table is provided with a cooling station and a cleaning station, which can be used to cool and clean the tempering box 2 after the experiment, so as to keep the tempering box 2 clean, ensure that the formula salt material filled into it each time is accurate and not contaminated, and ensure the accuracy of the tempering experiment results.

[0047] In some embodiments of this application, a cleaning nozzle and a drying duct are provided at the cleaning station. The tempered glass case 2 is quickly prepared by washing and drying to conduct multiple experiments.

[0048] Combination Figures 1 to 7 As shown, the working principle of this application is illustrated using a production process as an example:

[0049] First, fill tempering furnace 1 with approximately 3 / 4 salt, set the target temperature, and heat until the salt is completely melted. Second, add the target proportion of salt to tempering tank 2; the mass is not limited, but it must be enough to completely submerge the glass to be tested after melting. Third, use double hooks to hook the connecting lugs 223, lift tempering tank 2, and slowly lower it into the salt bath of tempering furnace 1, suspending it on the surface of the molten salt. Fourth, wait for the salt in tempering tank 2 to completely melt for the preset time (e.g., after 20 minutes), then... Glass preheated within the range of 0-300℃ for 5-120 minutes and any suitable glass carrier 3 (size and shape not fixed, as long as it fits) are placed in the salt bath within the tempering tank 21, ensuring the glass is completely submerged in molten salt; Step 5: After strengthening, first remove the glass carrier 3 and the glass and place them in a safe location, then remove the tempering box 2, pour the salt inside into a waste salt collection container, place it in a cooling station for cooling, then clean and dry it in a cleaning station, and after adding new salt, conduct the experiment again. The embodiments of this application have a simple structure, low cost, and are easy to use.

[0050] In summary, the glass tempering equipment of this application includes: a tempering furnace, a tempering box, and a hoisting mechanism; the tempering furnace has a hollow structure to form a molten salt bath space; the hoisting mechanism can connect to the tempering box and hoist it into the tempering furnace; the tempering box includes: a tempering tank and a suspension frame; the tempering tank contains salt for ion exchange; the suspension frame is connected above the tempering tank and extends outwards and upwards to form a suspension cavity, allowing the tempering box to suspend on the surface of the molten salt in the tempering furnace. This glass tempering equipment allows for the independent tempering of small batches of glass within a large tempering furnace by hoisting the tempering box, eliminating the need to replace the salt throughout the entire tempering furnace, thus significantly reducing the difficulty and time cost of salt replacement while saving salt. Furthermore, the tempering box is equipped with a suspension frame. This frame prevents the salt from flowing into the tempering furnace and contaminating the mass-produced salt, while also increasing the contact area between the tempering box and the furnace. This allows the tempering box to remain suspended on the surface of the molten salt during the tempering experiment, preventing it from sinking to the bottom and facilitating lifting, handling, and removal. Therefore, this application effectively reduces the cost and time associated with tempering salt before mass production. Its structure is simple, low-cost, and easy to use.

[0051] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
