Description

Technical Field

[0001] This invention belongs to the technical field of glass furnace material channels for high lead-out substrates, specifically relating to a platinum material channel structure and material channel cooling section of a glass furnace material channel cooling section. Background Technology

[0002] In the production of substrate glass, to reduce the impact of contact between molten glass and refractory materials on the glass composition, platinum feed channels are typically used to connect the furnace and forming equipment to improve the stability of the glass composition. Platinum feed channels are used to clarify, homogenize, stir, and regulate the temperature of the molten glass. Each section of the platinum feed channel is required to stably perform its specific function at its designated temperature. The platinum feed channel process is extremely critical, playing a crucial role in connecting preceding and following processes. Furthermore, since platinum feed channels are made of the precious metal platinum and its alloys, their condition significantly impacts the glass production cost, efficiency, and quality of the production line. Currently, under normal operating conditions, the operating temperature of platinum feed channel structures is generally above 1000℃. Due to prolonged high-temperature operation, the outer surface structure of the platinum feed channel is prone to deformation, causing the tube wall to thin, potentially leading to molten glass leakage and equipment damage.

[0003] As an improvement, the current platinum feed channel structure only uses an elliptical closed structure to provide support and strength for the platinum body. It can only serve as a support point on a nearly circular, flattened elliptical shape, structurally supporting the entire platinum body structure of the cooling section. However, if external factors affect the platinum surface and apply external forces, such as deformation of the outer refractory material compressing the platinum body or excessive pressure in the internal molten glass causing outward expansion, the flattened elliptical shape will inevitably deform. This will damage the platinum body structure of the cooling section, leading to cracks, dents, twisting, and bending in the platinum channel. Therefore, in summary, the current platinum feed channel structure lacks structural stability under high-temperature environments or after applying certain external forces. The structure is prone to deformation, which may lead to molten glass leakage, equipment damage, or even production line shutdowns, significantly impacting production costs and efficiency. Summary of the Invention

[0004] This invention provides a platinum material channel structure and a material channel cooling section for a glass furnace. The purpose is to solve the problem that the outer surface of the current platinum material channel structure is prone to deformation when it is used in a high-temperature environment or after a certain external force is applied. This may lead to glass melt leakage, equipment damage, or even production line shutdown, which has a relatively serious impact on production costs and efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The present invention provides a platinum material channel structure for the cooling section of a glass furnace material channel. The platinum material channel structure includes a glass liquid containing cavity, which has a glass liquid inlet and a glass liquid outlet. The glass liquid inlet and the glass liquid outlet can be connected to the furnace and the forming equipment respectively, so as to provide a buffer space for glass forming. A glass liquid containing cavity forms a glass liquid channel between a glass liquid inlet and a glass liquid outlet. A stable support structure is provided on the outer surface of the glass liquid containing cavity, and at least a portion of the stable support structure has a protruding structure along the outer surface of the glass liquid containing cavity. The stable support structure includes a stabilizing component, which includes at least one first rib, which is disposed in the glass liquid receiving cavity along the flow direction of the glass liquid.

[0006] In some embodiments, the stabilizing support structure further includes at least one second rib located near the molten glass inlet, and the second rib is arranged around the periphery of the molten glass inlet along the opening direction of the molten glass inlet.

[0007] Furthermore, two second ribs are provided, with the other second rib arranged around the periphery of the glass melt outlet along the opening direction of the glass melt outlet, and the two ends of the first rib are respectively connected to the two second ribs.

[0008] Furthermore, the first rib and the second rib form a first protrusion and a second protrusion on the outer surface of the glass liquid receiving cavity, respectively, with the height of the first protrusion being less than the height of the second protrusion.

[0009] In some embodiments, the glass melt containing cavity is a cooling section platinum cylinder, which has an upper flat portion and a lower flat portion arranged vertically, and the two ends of the upper flat portion and the lower flat portion are connected by curved portions.

[0010] Furthermore, the first rib is configured as several ribs, which are located in the upper plane portion and the lower plane portion respectively, and are arranged at intervals.

[0011] Furthermore, the first and second reinforcing bars are arranged vertically on the plane located on the upper or lower plane portion.

[0012] Furthermore, the spacing between several first ribs located in the upper or lower plane portion is equal.

[0013] In some embodiments, the periphery of the glass melt containing cavity is provided with refractory material.

[0014] The present invention also provides a material channel cooling section, which includes the platinum material channel structure of the glass furnace material channel cooling section described above.

[0015] Compared with the prior art, the platinum material channel structure and material channel cooling section of the glass furnace of the present invention have the following beneficial effects: This invention discloses a platinum material channel structure for the cooling section of a glass furnace. The platinum material channel structure includes a molten glass receiving cavity with a molten glass inlet and an outlet. The inlet and outlet can be connected to the furnace and forming equipment, respectively, to provide buffer space for glass forming. A molten glass channel is formed between the inlet and outlet of the molten glass receiving cavity. A stable support structure is provided on the outer surface of the cavity, at least a portion of which has protrusions along its outer surface. The stable support structure includes a stabilizing component, which includes at least one first rib disposed in the cavity along the flow direction of the molten glass. Based on the above, the molten glass receiving cavity of this invention has a molten glass inlet and outlet for connecting the furnace and forming equipment, providing necessary buffer space for the molten glass before forming. The stable support structure includes at least one first rib disposed along the flow direction of the molten glass. The first rib not only enhances the stability of the material channel structure but also further increases the contact area and support force with the external structure through its protrusions. This invention effectively improves the overall strength and rigidity of the platinum feed channel structure by using a stable support structure and reinforcing ribs, reducing the risk of deformation caused by high temperatures and molten glass flow. The design of the molten glass containment cavity ensures a smooth transition during the flow of the molten glass, reducing fluctuations and turbulence, which is beneficial to the stability of subsequent forming processes and product quality. Furthermore, the platinum feed channel structure design enhances the stability of the feed channel structure, reducing maintenance frequency and downtime to a certain extent, thereby improving the operating efficiency and quality of the glass production line.

[0025] How can we reduce the deformation of the platinum feed channel at the source, and improve the production efficiency of substrate glass, extend the service life of the platinum feed channel equipment, and reduce production costs without changing the operation process of the platinum feed channel?

[0026] like Figure 1 and Figure 2 As shown, the present invention provides a platinum material channel structure for the cooling section of a glass furnace material channel. The platinum material channel structure includes a glass liquid containing cavity, which has a glass liquid inlet 1 and a glass liquid outlet 2. The glass liquid inlet 1 and the glass liquid outlet 2 can be connected to the furnace and the forming equipment respectively, so as to provide a buffer space for glass forming. A glass liquid containing cavity forms a glass liquid channel between the glass liquid inlet 1 and the glass liquid outlet 2. A stable support structure is provided on the outer surface of the glass liquid containing cavity, and at least a portion of the stable support structure has a protruding structure along the outer surface of the glass liquid containing cavity. The stable support structure includes a stabilizing component, which includes at least one first rib 3, which is disposed in the glass liquid receiving cavity along the flow direction of the glass liquid.

[0027] This invention adds a stable support structure to the platinum body structure of the cooling section, thereby ensuring the stable support of the molten glass container within the cooling section. This invention ensures that the platinum cylinder 5 (the platinum body of the cooling section) is not easily deformed, while also preventing the thermocouple wires connected to the surface of the platinum body from breaking. If the surface of the platinum body undergoes significant deformation, the thermocouple wires connected to it, because their fixed positions remain unchanged, could be torn. Therefore, the ribs prevent deformation of the platinum body surface and also prevent the thermocouple wires from breaking, thus improving the overall stability of the structure.

[0028] In some embodiments, the present invention adds at least one second rib 4, which is located near the glass melt inlet 1 and is arranged around the inlet to strengthen the support of that area. Further, the present invention provides two second ribs 4, with the other rib surrounding the glass melt outlet 2, and both ends of the first rib 3 connected to these two second ribs 4, forming a more complete support frame. The present invention adds a longitudinal stiffener in the middle straight section of the cooling section. Since platinum is a metal object, it will inevitably experience processing stress during welding and assembly, causing surface deformation of the platinum structure and affecting the processing quality of the platinum body. This results in a significant reduction in the overall structure of the platinum body after processing, thus diminishing its usability. Therefore, the addition of a longitudinal stiffener in the middle straight section of the cooling section also plays a role in supporting and stabilizing the platinum body structure during processing.

[0029] The platinum feed channel structure of the cooling section of the glass furnace of this invention is based on the original platinum feed channel structure, with the addition of a first rib 3 (longitudinal rib) and a second rib 4 (transverse rib) in the cooling section. When the temperature of the platinum feed channel structure in the cooling section gradually rises above 1000°C, the platinum metal will deform under the continuous high-energy heat, thus causing changes in the overall structure of the platinum feed channel and affecting its performance. Therefore, the addition of the first rib 3 and the second rib 4 in this invention can mitigate and reduce the deformation caused by heating.

[0030] Based on this, when the platinum body in the cooling section gradually heats up to above 1000℃, the interior of the platinum body will be in a hollow state for a period of time, meaning there is no molten glass present. Furthermore, the platinum tube itself softens at high temperatures. Therefore, at high temperatures, the platinum, especially the flattened upper part of the flattened oval shape, will collapse downwards due to gravity. Thus, the added first rib 3 and second rib 4 provide support, stabilizing the flattened part at high temperatures.

[0031] During the manufacturing process of the platinum cylinder 5 in the cooling section, because the flat elliptical shape is not like a circle, it is very easy to manufacture by calculating a series of formulas such as diameter and area. Furthermore, the manufacturing accuracy can be verified through these calculation formulas. However, the flat elliptical shape is not a regular shape and cannot be completely verified according to the calculation formulas. Therefore, by adding the first rib 3 and the second rib 4, the actual shape of the flat elliptical shape can be verified based on the lengths of the first rib 3 and the second rib 4. Moreover, the first rib 3 and the second rib 4 also play a role in stabilizing the shape of the measured object during the verification process.

[0032] In some embodiments, the second rib 4 of the present invention is provided on both sides of the inlet and outlet, and is connected with the first rib 3 to form a stable support system, which comprehensively improves the deformation resistance of the cooling section platinum cylinder 5, so that the cooling section platinum cylinder 5 can better maintain its shape and stability when subjected to high temperature and glass liquid flow pressure, and reduces deformation and damage caused by long-term use.

[0033] like Figure 3 As shown, the first rib 3 and the second rib 4 of the present invention form a first protrusion 31 and a second protrusion 41 on the outer surface of the glass melt receiving cavity, respectively. The height of the first protrusion 31 is smaller than the height of the second protrusion 41. Through the design of protrusions of different heights, the present invention allows the platinum cylinder 5 of the cooling section to have different support strengths and contact areas at different positions, better adapting to the different stress and temperature distributions generated during the glass melt flow. The larger second protrusion 41 provides stronger wear-resistant protection in the areas of the glass melt inlet 1 and the glass melt outlet 2, reducing wear caused by friction.

[0034] In some embodiments, the cooling section platinum cylinder 5 of the present invention has an upper flat portion 51 and a lower flat portion 52 arranged vertically, and a curved portion 53 connecting the two portions. A plurality of first ribs 3, respectively located on the upper flat portion 51 and the lower flat portion 52, are arranged at intervals. The cooling section platinum cylinder 5 is a pipe-like structure with a closed surface and molten glass flowing inside, and the entire upper and lower sides of the cooling section platinum cylinder 5 are encased in refractory material. The first ribs 3 and second ribs 4 are arranged vertically when located on the plane of the upper flat portion 51 or the lower flat portion 52. The cooling section platinum cylinder 5 of the present invention improves the uniform conduction and dissipation of heat through the design of the upper and lower flat portions, increasing cooling efficiency. The smooth transition of the curved portion 53 reduces stress concentration points and enhances the overall stability of the cooling section platinum cylinder 5. Furthermore, the distribution of multiple ribs in the present invention ensures effective support for the upper and lower flat portions at different positions, reducing deformation caused by excessive local stress.

[0035] This invention specifically designs the arrangement of the first rib 3 and the second rib 4 in the platinum cylinder 5 of the cooling section. Specifically, the spaced arrangement of the first rib 3 facilitates the uniform distribution and conduction of heat, further improving the cooling effect. The vertical arrangement of the first rib 3 and the second rib 4 gives the platinum cylinder 5 of the cooling section greater rigidity in the vertical direction, better resisting deformation forces that may be caused by external forces and temperature changes. Furthermore, the vertical arrangement optimizes the space utilization between the first rib 3 and the second rib 4, making the platinum cylinder 5 of the cooling section more compact.

[0036] In practical applications, the plurality of first stiffeners 3 of this invention can be arranged at equal or unequal intervals, depending on the specific needs. As a preferred embodiment, the invention can arrange the plurality of first stiffeners 3 at equal intervals. This equal-interval design ensures that the force borne by each first stiffener 3 is more uniform, avoiding damage caused by localized stress concentration. Furthermore, equal intervals simplify the processing and manufacturing process, improving production efficiency and reducing costs.

[0037] This invention also provides a material channel cooling section, which includes the platinum material channel structure of the aforementioned glass furnace material channel cooling section. Through the design of the platinum material channel structure, the material channel cooling section can achieve better stability, high-temperature resistance, and cooling efficiency. The material channel cooling section of this invention can be widely used in glass production lines to improve production efficiency and product quality.

[0038] In summary, this invention provides a platinum feed channel structure and a feed channel cooling section for a glass furnace. Through the designed platinum feed channel structure, the stability, high-temperature resistance, and cooling efficiency of the glass furnace feed channel cooling section are significantly improved. The robust support structure and multi-rib layout effectively enhance the overall strength and rigidity of the feed channel, reducing the risk of deformation. The feed channel cooling section using the platinum feed channel structure of this invention can operate stably in glass production, thereby improving its production efficiency and demonstrating excellent applicability.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention according to the description and above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, based on the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
