Description

Heat sink and method for platinum channel glass liquid TECHNICAL FIELD

[0001] The present application belongs to the technical field of temperature control for substrate glass manufacturing, and particularly relates to a heat sink and method for platinum channel glass liquid. BACKGROUND

[0002] At present, substrate glass is an important component in the display industry chain. With the development of new display industry towards larger size, new technical requirements are put forward for the production of substrate glass. High production capacity corresponds to high lead-out amount, which also means larger and more complex production and manufacturing equipment. The kiln needs higher melting efficiency and more stable melting process, and the channel needs greater heat dissipation capacity and more excellent clarification and homogenization capacity. For the channel equipment, under the premise that the overall layout of the existing equipment does not change, the higher process requirements are basically realized by increasing the size of the equipment, especially in the cooling and heat dissipation link. Because the environmental control capacity has reached the upper limit, only by continuously lengthening the equipment to provide more heat dissipation time can the preset heat dissipation gradient be realized. Since heat dissipation is a process of heat transfer from inside to outside of the glass liquid, it means that the internal temperature is always higher than the external temperature, and with the extension of the cooling time, the temperature difference between the inside and the outside will further increase, which has a bad influence on the glass uniformity control, and finally leads to the decline of the forming quality. Therefore, for a long time, the research and design of the temperature difference between the inside and the outside of the glass liquid and how to improve the heat dissipation capacity of the glass liquid as a whole are the necessary content and core restricting item in the development of large flow substrate process.

[0003] As an improvement, the researchers currently consider the existing problems and related phenomena in various practical processes, and set the cooling area outside the platinum pipeline to cool the glass liquid inside the platinum pipeline, which to some extent achieves the purpose of heat dissipation and cooling. However, since the cooling is carried out outside the platinum pipeline, the glass liquid near the inner center of the pipeline is relatively difficult to cool quickly because the whole glass liquid is in the platinum pipeline. Therefore, in the process of cooling the glass liquid inside the platinum pipeline, the heat dissipation efficiency is not high enough, and it is relatively easy to form a large temperature difference in the radial direction of the glass liquid in the platinum pipeline, which is not conducive to the uniformity of the whole glass, and affects the subsequent process control.

The material of the external air guide assembly is composed of stainless steel and platinum rhodium alloy, that is, the external structure is made of stainless steel material, and the contact area with the platinum gold channel pipe 1 is made of platinum rhodium alloy.

[0054] The two annular pipes 31 of the present application are made of 316 stainless steel, and the working environment is about 300 DEG C. The annular diameter is related to the diameter of the platinum gold channel pipe 1, and is generally larger than 150mm-300mm, mainly to ensure that the two annular pipes 31 are outside the entire channel refractory material, so as to ensure the safe environmental temperature. The pipe body cross section diameter of the two annular pipes 31 is 30mm, which can ensure sufficient gas residence time, and the wall thickness is 2.5mm, which can meet the strength requirement. The shunt pipe 32 of the present application mainly transmits the gas flow in the annular pipe 31 to the internal circulating cooling pipe 2, the shunt pipe 32 is made of platinum rhodium alloy, and can be connected with the annular main pipe 3-1 in a threaded or flange form, and is communicated with the internal cooling branch pipe 2-2 through four holes in the platinum gold channel pipe 1, and the connection mode is also a flange form, and sealing is required; the pipe diameter of the shunt pipe 32 is 20mm, and the wall thickness is 2.0mm.

[0055] The external connecting pipe 33 of the present application is made of the same material as the annular pipe 31, and the pipe diameter is 20mm. The external connecting pipe is provided with compressed gas for temperature regulation, and the flow of the external cooling gas supply equipment is controlled by a valve, and the valve switching amount is controlled by a distributed control system.

[0056] As shown in Figure 6, the device body of the present application includes a plurality of device bodies, and the plurality of device bodies are arranged along the axial direction of the platinum gold channel 1.

[0058] As shown in Figure 8, based on the heat dissipation device, a heat dissipation method for the heat dissipation device for the platinum channel glass liquid of the application comprises the following steps:

[0059] S1, install the internal cooling assembly and the external air guide assembly in the platinum channel 1, check the sealing, check the integrity of the monitoring unit, and connect the external air guide assembly to the external cooling gas supply device;

[0062] The application mainly adopts the airflow cooling mode, and considering that the internal structure is made of platinum-rhodium alloy material and the temperature is above 1500℃, the platinum gold has the problem of oxidation and volatilization, so in the actual airflow scheme, temperature-adjustable inert gas such as nitrogen or argon is selected, which can protect the platinum gold and inhibit the internal high-temperature oxidation reaction, thereby prolonging the service life of the equipment. In Figure 8, the working principle of cooling is shown. The gas enters from the inlet pipe, is uniformly sent to the internal circulating cooling pipe 2 through the annular pipe 31, directly takes away the heat inside the glass fluid, and flows out from the external interface on the outlet side. The gas is continuously supplied through the kinetic energy system, the flow meter monitors the flow in real time, the plug-in thermocouple 5 continuously monitors the temperature of the inlet airflow and the outlet airflow, the temperature difference is determined, and the temperature displayed by the welded thermocouple 6 on the platinum channel pipe 1 is combined. The distributed control system outside can automatically adjust the flow and the temperature of the inlet airflow. For the temperature of the glass inside, the plug-in thermocouple 5 on the platinum channel pipe 1 can monitor the temperature of the core of the glass, and then control the cooling process of the entire glass liquid. Based on the application, the heat dissipation efficiency can be effectively improved by 1-3 times through experiments. For larger size and larger flow new lines, efficient heat dissipation can be realized, and the internal and external temperature difference of the glass liquid can be controlled within 5℃, which is relatively significantly improved from the original 30℃-60℃ temperature difference. It provides excellent basic conditions for uniform overflow and provides a good foundation for subsequent glass processing, and has better practical significance.
