Description

Technical Field

[0001] The utility model relates to the technical field of substrate glass production, and specifically relates to a safety guarantee system for the cooling water of the substrate glass channel flange. Background Technique

[0002] In the high-end manufacturing field of liquid crystal glass, the melting, transmission, and forming processes of glass raw materials have a decisive impact on the quality and performance of the final product. Traditionally, glass raw materials are efficiently melted in an electric furnace with pure oxygen combustion. This process not only requires extremely high temperature control accuracy but also ensures the purity and uniformity of the molten glass liquid. Subsequently, the molten glass liquid needs to flow through a high-temperature platinum channel, which, with its excellent high-temperature resistance and corrosion resistance, becomes a key bridge connecting the furnace and the forming equipment.

[0003] However, during the process of transporting the glass liquid from the furnace to the forming process, maintaining its temperature stability is a major technical challenge. Since the glass liquid is extremely sensitive to temperature, any temperature fluctuation may cause changes in its internal structure, thereby affecting the optical properties, mechanical strength, and surface quality of the product. Therefore, designing an efficient and stable heating system to ensure that the glass liquid maintains a constant high temperature state in the transmission channel has become the key to improving the production quality of liquid crystal glass.

[0004] In the prior art, the temperature of the transmission channel is usually controlled by means of segmented heating, but this method often has problems such as uneven heating, high energy consumption, and high equipment maintenance costs. In addition, long-term high-temperature operation will also cause thermal stress damage to the heater and its accessories, shortening the service life of the equipment and increasing production risks.

[0005] In view of the above problems, this design proposes an innovative heating and cooling system to optimize the glass liquid transmission link in the liquid crystal glass production process. Content of the Utility Model

[0006] In view of the deficiencies of the prior art, the utility model provides a safety guarantee system for the cooling water of the substrate glass channel flange, which solves the problems raised in the above background technique.

[0007] To achieve the above object, the utility model is realized through the following technical solutions: A safety guarantee system for the cooling water of the substrate glass channel flange, comprising:

[0011] Filter, the filter is connected to the plate heat exchanger, and the filter can remove impurities in RO pure water;

[0012] Platinum channel, heaters are installed at intervals outside the platinum channel. RO pure water can be delivered to the heaters and cooled down by them;

[0013] Make-up water tank, the make-up water tank is connected to the water tank and has a height difference with the water tank, and can supply RO pure water to the water tank.

[0014] Furthermore, a liquid level gauge is installed outside the water tank, and the liquid level gauge can reflect the liquid level height in the water tank.

[0015] Furthermore, two sets of the water supply pump group and the plate heat exchanger are provided, and any one of them can be started for use.

[0016] Furthermore, a heat exchange pre-pipeline is commonly connected between the water outlet end of the water supply pump group and the water inlet end of the plate heat exchanger.

[0017] Furthermore, a filtration pre-pipeline is commonly connected between the water outlet end of the plate heat exchanger and the water inlet end of the filter. A pre-filter pressure gauge is connected in series in the section of the filtration pre-pipeline. A heater flange coil inlet pipe is commonly connected between the water outlet end of the filter and the water inlet end of the heater. A post-filter pressure gauge is connected in series in the section of the heater flange coil inlet pipe.

[0018] Furthermore, a make-up water pipeline is commonly connected between the water outlet end of the make-up water tank and the water inlet end of the water tank.

[0019] The present utility model provides a safety guarantee system for the cooling water of the substrate glass channel flange. Compared with the prior art, it has the following beneficial effects:

[0020] For the safety guarantee system of the cooling water of the substrate glass channel flange, the system realizes precise heating of the glass liquid by installing flange direct heating devices on each section of the transmission channel, ensuring that its temperature does not drop during the transmission process.

This measure effectively reduces the working temperature of the heater, reduces the damage to the equipment caused by thermal stress, and thus improves the stability and reliability of the system.

[0021] In addition, this design also focuses on the safety guarantee of the water circulation system to ensure continuous and stable supply of water circulation under any circumstances, avoiding risks such as overheating and damage of equipment caused by water interruption. This safety guarantee measure not only improves the overall safety of the production line but also provides strong support for the continuous and efficient production of the enterprise.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-3, the utility model provides a technical solution: a safety guarantee system for cooling water of a substrate glass channel flange, which is composed of a water tank 1, a water supply pump group 2, a plate heat exchanger 3, a filter 4, a platinum channel 5 and a makeup water tank 6. Among them, RO pure water is stored inside the water tank 1, and a liquid level gauge 101 is installed outside the water tank 1. The liquid level gauge 101 can reflect the liquid level height of the RO pure water in the water tank 1. The water inlet end of the water supply pump group 2 is directly connected to the water outlet end of the water tank 1. The water supply pump group 2 can pump the RO pure water in the water tank 1 outward. The plate heat exchanger 3 is connected to the water supply pump group 2 through a heat exchange pre-pipeline 7. The plate heat exchanger 3 can cool down the RO pure water. The filter 4 is connected to the plate heat exchanger 3 through a filter pre-pipeline 8. The filter 4 can remove impurities in the RO pure water. Heaters 51 are installed at intervals outside the platinum channel 5. Between the water outlet end of the filter 4 and the water inlet end of the heater 51, there is a heater flange coil water inlet pipe 9. RO pure water can be transported to the heater 51 and cool it down. The makeup water tank 6 is connected to the water tank 1 and has a height difference with the water tank 1. Between the water outlet end of the makeup water tank 6 and the water inlet end of the water tank 1, there is a makeup water pipeline 61 in common, which can supplement RO pure water to the water tank 1. Between the water outlet end of the heater 51 and the water inlet end of the water tank 1, there is a heater flange coil return pipe 10 in common;

[0028] In addition, two sets of the water supply pump group 2 and the plate heat exchanger 3 are provided, and any one of them can be started for use. That is to say, the two sets of the water supply pump group 2 and the plate heat exchanger 3 are set as one standby and one in use. When one of them fails and cannot be used, the other can be started for use to achieve non-stop operation, providing the fault tolerance rate of the system.

[0029] Finally, a pre-filter pressure gauge 81 is connected in series in the section of the filter pre-pipeline 8, and a post-filter pressure gauge 91 is connected in series in the section of the heater flange coil water inlet pipe 9. By comparing the pre-filter pressure gauge 81 and the post-filter pressure gauge 91, it can be known whether the inside of the filter 4 is blocked. Because after being blocked, the value of the post-filter pressure gauge 91 will be significantly smaller than the value of the pre-filter pressure gauge 81.
