Description

Technical Field

[0001] This utility model belongs to the field of substrate glass technology and relates to a channel structure for substrate glass manufacturing. Background Technology

[0002] In the field of substrate glass manufacturing, with continuous technological advancements, the capabilities of high-generation, high-flow-rate channel equipment are facing increasingly stringent requirements, leading to a continuous increase in the size of the channel body. The channel body serves as a crucial carrier for the flow and handling of molten glass.

[0003] The platinum channel, as the core structure of the channel body, undertakes a series of critical heat treatment and forming guidance tasks during the glass melting and forming process. The cooling section plays a crucial role in precisely controlling the temperature and ensuring uniform heat dissipation during the glass forming process. The installation structure and process quality of the cooling section are closely related to the uniformity of heat dissipation of the glass and the final forming quality. Only by ensuring precise installation and excellent process of the cooling section can a stable and uniform heat dissipation environment be provided for the glass, thereby producing high-quality substrate glass.

[0004] The existing cooling section flat tube adopts a near-elliptical structure. The near-elliptical structure has a relatively large upper and lower surface area and a thin wall thickness. During the processing, due to the inherent properties of the material and the limitations of the processing technology, the flat tube is prone to collapse and deformation, resulting in uneven filling gaps between the channel body and the refractory material.

[0005] During installation, the existing steel structure is set up as an integrated unit, which makes it impossible to effectively and accurately adjust the filling gaps. The problem of inconsistent gaps becomes more and more serious during installation, resulting in uneven filling material thickness. This directly affects the uniformity of heat transfer, leading to uneven heat dissipation of the internal molten glass and seriously affecting the overflow quality. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a channel structure for substrate glass manufacturing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a channel structure for substrate glass manufacturing, including several channel units. Each channel unit includes a steel structure and a channel disposed on the upper end of the steel structure. The channel is detachably connected to the steel structure through a connector. The channel includes a platinum body, a first refractory material, a second refractory material, and a third refractory material. The platinum body is installed on the upper end of the second refractory material, and the first refractory material and the third refractory material are disposed on both sides of the platinum body.

[0008] Furthermore, the gap between the first and third refractory materials and the platinum body is 10-20 mm.

[0009] Furthermore, the steel structure includes a bottom support steel structure and a top support steel structure. The second refractory material is disposed on the upper end of the bottom support steel structure. The two ends of the bottom support steel structure are fixedly connected to the top support steel structure through connectors. The top support steel structure is installed on the ground, and the side walls of the top support steel structures of two adjacent channel units abut against each other.

[0010] Furthermore, the length of the first refractory material is the same as the length of the third refractory material, and the length of the first refractory material is less than the length of the bottom supporting steel structure.

[0011] Furthermore, the connector is a steel structure, and its two ends are detachably connected to the bottom support steel structure and the top support steel structure respectively by fasteners.

[0012] Furthermore, the angle between the channel and the ground is 10-30°.

[0013] Furthermore, the first refractory material, the second refractory material, and the third refractory material are made of alumina.

[0014] Furthermore, heating holes are provided on the first refractory material, the second refractory material, and the third refractory material.

[0015] Furthermore, the number of the connectors is greater than or equal to 4, and is an even number.

[0016] Furthermore, the fastener is a nut.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects: This utility model discloses a channel structure for substrate glass manufacturing. Each channel unit includes a steel structure and a channel located at the upper end of the steel structure. The channel is detachably connected to the steel structure via connectors. During or after installation, each channel unit can be finely adjusted. By adjusting the connectors, the height and horizontal position of each channel unit relative to the steel structure and adjacent units can be precisely controlled, ensuring that the filling gap between the platinum body and the first and third refractory materials remains uniform along the entire length of the cooling section.

[0018] This invention relates to a channel structure for manufacturing substrate glass. The gap between the first and third refractory materials and the platinum body is 10-20mm. By precisely controlling the gap between the first and third refractory materials and the platinum body, the distribution of the filler can be precisely controlled, ensuring that the thickness of the filler is uniform, thereby improving the heat dissipation performance of the molten glass.

[0019] This invention relates to a channel structure for manufacturing substrate glass. The angle between the channel and the ground is 10-30°, which promotes a more stable and smooth laminar flow of molten glass and avoids temperature differences caused by uneven local mixing.

[0020] This invention relates to a channel structure for manufacturing substrate glass. The first, second, and third refractory materials are made of alumina, which has good fire resistance, provides effective protection for the platinum body, and extends the service life of the channel structure.

[0021] This utility model discloses a channel structure for substrate glass manufacturing, wherein the number of connectors is greater than or equal to 4 and is an even number, thereby enhancing the stability and reliability of the entire channel structure.

[0022] This utility model discloses a channel structure for manufacturing substrate glass. Heating holes are provided on the first, second, and third refractory materials. When the molten glass flows through the platinum body, if a local temperature is detected to be lower than a preset value, directional heating can be performed through the heating holes in the corresponding area to avoid abnormal viscosity of the molten glass due to temperature fluctuations. This ensures that the first, second, and third refractory materials maintain uniform deformation during the thermal expansion process.

[0023] This utility model discloses a channel structure for manufacturing substrate glass, wherein the length of the first refractory material is less than the length of the bottom supporting steel structure, so that the first refractory material can be finely adjusted on the bottom supporting steel structure.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] Example 1 This utility model discloses a channel structure for substrate glass manufacturing, such as... Figure 1 The diagram shows several channel units, each including a steel structure 1 and a channel 2 disposed on the upper end of the steel structure 1. The channel 2 is detachably connected to the steel structure 1 via a connector 3. The channel 2 includes a platinum body 21, a first refractory material 22, a second refractory material 23, and a third refractory material 24. The platinum body 21 is installed on the upper end of the second refractory material 23, and the first refractory material 22 and the third refractory material 24 are disposed on both sides of the platinum body 21.

[0028] In existing technologies, the flat tube of the cooling section in the substrate glass manufacturing process adopts a near-elliptical structure. Due to material properties and processing limitations, the flat tube is prone to collapse and deformation, resulting in uneven filling gaps between channel 2 and the refractory material. The integrated steel structure 1 cannot adjust the gaps, and the inconsistent gaps during installation exacerbate the difference in filler thickness, affecting the uniformity of heat transfer and ultimately leading to uneven heat dissipation of the molten glass.

[0029] Each channel unit in this application consists of a steel structure 1 and a channel 2, with the channel 2 being detachably connected to the steel structure 1 via a connector 3. The channel 2 includes a platinum body 21 and refractory materials, wherein the platinum body 21 is installed on the upper end of the second refractory material 23, and the first refractory material 22 and the third refractory material 24 are located on both sides of the platinum body 21, respectively.

[0030] Steel structure 1 is a metal support frame, which can be assembled by welding or bolting steel sections, and is used to support the weight of channel 2. Detachable connectors refer to connecting parts that allow for repeated assembly and disassembly, such as those using bolts or snap-fit ​​structures, used to adjust the relative position of the channel and the steel structure. Platinum body 21 refers to the main body of the flow channel made of platinum metal, formed by casting or stamping processes, used to guide the flow of molten glass. Refractory material refers to non-metallic materials resistant to high temperatures.

[0031] The steel structure 1 forms an adjustable assembly relationship with the channel 2 via connector 3. During installation, the platinum body 21 is supported by the second refractory material 23, while the first and third refractory materials 22 and 24 on both sides are clamped and fixed through gap control. When the gap needs to be adjusted, the connector 3 is loosened to move the position of the channel 2, so that the contact surfaces of the second refractory material 23 and the platinum body 21 are realigned, and then the connector 3 is tightened to complete the positioning. The gap is dynamically adjusted during the installation stage to ensure uniform filling of the refractory material. The first and third refractory materials 22 and 24 form a symmetrical clamping structure, reducing the risk of deformation of the platinum body 21. Figure 2 As shown.

[0032] The gaps between the first refractory material 22 and the third refractory material 24 and the platinum body 21 are 10-20 mm. This limited gap range ensures the uniform distribution of the filling material. During the assembly of the channel unit, the first refractory material 22 and the third refractory material 24 are pre-positioned on both sides of the platinum body 21, and the gaps are controlled within the range of 10-20 mm using connectors 3. This ensures a balance between the flowability and density of the filling material; too small a gap will result in insufficient material filling, while too large a gap may cause localized accumulation. Precise control of the gaps ensures the stability of the heat transfer path.

[0033] In traditional channel structures, there is a lack of effective means to control the gap between the refractory material and the platinum body 21, resulting in large fluctuations in the thickness of the filling layer. This application controls the gap so that the filling material forms a heat insulation layer of uniform thickness after curing, avoiding heat loss caused by localized thinness or stress concentration caused by excessive thickness.

[0034] The steel structure 1 includes a bottom support steel structure 11 and a top support steel structure 12. The second refractory material 23 is installed on the upper end of the bottom support steel structure 11. The two ends of the bottom support steel structure 11 are fixedly connected to the top support steel structure 12 through connectors 3. The top support steel structure 12 is installed on the ground, and the side walls of the top support steel structures 12 of two adjacent channel units abut against each other.

[0035] The bottom supporting steel structure 11 and the top supporting steel structure 12 form a separate structure via connectors 3. During installation, the top supporting steel structure 12 can be fixed first, and then the bottom supporting steel structure 11 can be leveled by adjusting the position of connectors 3. The second refractory material 23 is precisely installed on the upper end of the bottom supporting steel structure 11, and the gaps on both sides can be finely adjusted by adjusting the installation position of connectors 3. The top supporting steel structures 12 of adjacent channel units form a continuous supporting surface through side wall contact, avoiding structural misalignment caused by unit splicing.

[0036] Existing steel structures employ an integrated design, resulting in an inability to adjust the gaps between refractory materials. This application addresses this by combining a separate steel structure 1 with connectors 3, allowing independent adjustment of the position of the bottom supporting steel structure 11. This enables precise control of the assembly gap between the second refractory material 23 and adjacent refractory materials. This avoids variations in filler thickness caused by uneven gaps, thereby improving the uniformity of heat dissipation from the molten glass and reducing glass quality defects caused by uneven temperature distribution during the forming process.

[0037] The length of the first refractory material 22 is the same as the length of the third refractory material 24, but the length of the first refractory material 22 is less than the length of the bottom supporting steel structure 11. The first refractory material 22 and the third refractory material 24 are symmetrically arranged on both sides of the platinum body 21 with the same length. The design of equal length ensures that the supporting force of the first refractory material 22 and the third refractory material 24 on the platinum body 21 is evenly distributed, avoiding deformation of the platinum body 21 due to uneven stress caused by the difference in length.

[0038] The length of the first refractory material 22 is less than the length of the bottom supporting steel structure 11, allowing for fine-tuning of the first refractory material 22 on the bottom supporting steel structure 11. By symmetrically arranging the first refractory material 22 and the third refractory material 24 of equal length and reserving adjustment space, the gap size can be dynamically compensated through translation, thereby ensuring consistent filler thickness and improving heat transfer uniformity.

[0039] The connector 3 is detachably connected to the bottom support steel structure 11 and the top support steel structure 12 at both ends by fasteners 4. By adjusting the tightness or position of the fasteners 4, the relative position between the bottom support steel structure 11 and the top support steel structure 12 can be finely adjusted, thereby controlling the uniformity of the gap between the second refractory material 23 and the platinum body 21.

[0040] The angle between channel 2 and the ground is 10-30°, achieved by adjusting the relative height of the bottom supporting steel structure 11 and the top supporting steel structure 12, or the installation position of the connector 3. This ensures that the molten glass can evenly contact the inner wall of the channel during flow, avoiding local stagnation or excessive flow rate differences. By adjusting the angle, the residence time of the molten glass in the cooling section can be optimized, ensuring uniform heat transfer. Existing cooling section channels are usually installed horizontally, which cannot adjust the flow state of the molten glass according to process requirements, resulting in uneven heat dissipation. This application introduces an adjustable tilt angle, allowing channel 2 to adapt to different molten glass flow rates and heat dissipation requirements, solving the problem of uneven heat dissipation caused by flow rate differences.

[0041] The first refractory material 22, the second refractory material 23, and the third refractory material 24 are made of alumina. Under high-temperature conditions, the alumina maintains the stability of the gap size through its own coefficient of thermal expansion and the platinum body 21. During installation, the structural strength of the alumina can resist the deformation caused by external forces during processing and installation, thereby ensuring a uniform distribution of the gap between the refractory material and the platinum body 21.

[0042] In summary, alumina refractory materials ensure uniform filler thickness and consistent heat transfer paths, thereby achieving uniform control of heat dissipation from molten glass.

[0043] Heating holes are provided on the first refractory material 22, the second refractory material 23 and the third refractory material 24.

[0044] The heating holes can be cylindrical, rectangular, or other regular shapes. They are used to house heating elements, such as resistance wires, electromagnetic induction coils, or gas pipes. By actively heating and adjusting the temperature distribution of the refractory material, the heat loss during the flow of molten glass is compensated, and the temperature uniformity within the channel is maintained.

[0045] During channel operation, the heat generated by the heating element is transferred to the platinum body 21 through the first refractory material 22, the second refractory material 23, and the third refractory material 24, forming a controllable temperature gradient. When the molten glass flows through the platinum body 21, if a local temperature is detected to be lower than a preset value, directional heating can be performed through the heating holes in the corresponding area to avoid abnormal viscosity of the molten glass due to temperature fluctuations. This ensures that the first refractory material 22, the second refractory material 23, and the third refractory material 24 maintain uniform deformation during thermal expansion, keeping the gap between the platinum body and the first refractory material 22 and the third refractory material 24 stable. This prevents thickness differences in the filler material due to gap changes, thereby optimizing the heat dissipation uniformity of the molten glass and improving the quality of substrate glass forming.

[0046] The number of connectors 3 is greater than or equal to 4, and is an even number. Connectors 3 detachably fix the bottom supporting steel structure 11 to the top supporting steel structure 12. In this embodiment, connectors 3 are steel structures, and the number of connectors 3 is set to an even number and symmetrically distributed to avoid structural displacement caused by uneven force on one side. The number of connectors 3 is greater than or equal to 4, which can form a multi-support point layout and enhance the stability of the overall structure.

[0047] During installation, the bottom support steel structure 11 and the top support steel structure 12 are fixed together by at least four connectors 3, which are symmetrically distributed in an even number on both sides of the bottom support steel structure 11. Two connectors are installed at each of the front and rear ends of the bottom support steel structure 11, forming a four-corner symmetrical fixing structure. During installation, the connectors 3 are locked to the bottom support steel structure 11 and the top support steel structure 12 in sequence using fasteners 4, forming a multi-point synchronous constraint. When it is necessary to adjust the gap between the second refractory material 23 and the platinum body 21, fine-tuning is achieved by symmetrically tightening and loosening the connectors 3 at different positions to ensure uniform force during gap adjustment.

[0048] like Figure 2 As shown, the connector 3 adopts a segmented installation structure, and each connector 3 includes two sets of fasteners 4, one upper and one lower. In this embodiment, the fasteners 4 are nuts. This application effectively eliminates structural deformation caused by excessive force at a single point by using an even number of connectors 3.

[0049] In summary, this application presents a channel structure for substrate glass manufacturing. Through modular segmented design and angle adjustment, the precise installation of the channel structure is achieved. This not only solves the problems encountered in the processing and installation of existing flat tube structures for cooling sections, but also effectively controls the filling gap between the refractory material and the platinum body, improving the heat dissipation uniformity and overflow quality of the molten glass.

[0050] Example 2 This utility model also provides a method for using a channel structure in substrate glass manufacturing, including the following steps: Install the steel structure 1 at a preset angle; pre-install the first refractory material 22, the second refractory material 23, and the third refractory material 24 with the platinum body 21; fix the pre-installed first refractory material 22 on the steel structure 1; make fine adjustments to the steel structure 1 according to the gap between the second refractory material 23, the third refractory material 24 and the steel structure 1, and fix it with the connector 3.

[0051] The preset angle refers to the tilt angle between the steel structure 1 and the ground. The preset angle provides a reference for the installation of the first refractory material 22, the second refractory material 23 and the third refractory material 24, ensuring the stability of the overall structure of the steel structure 1.

[0052] First, the steel structure 1 is installed on the ground at a preset angle. Then, the first refractory material 22, the second refractory material 23, and the third refractory material 24 are pre-installed with the platinum body 21 to form a preliminary combined structure. After installation on the steel structure 1, the position of the steel structure 1 is fine-tuned by observing the gaps between the first refractory material 22, the third refractory material 24, and the steel structure 1. During the adjustment process, the detachable nature of the connector 3 allows for repeated adjustments until the gaps are uniform. This application achieves precise gap control through the synergistic effect of pre-installation, fine-tuning, and detachable connectors, effectively solving the problem of uneven heat dissipation caused by uneven gaps.
