[0009] Furthermore, the traction base (2) employs a variable thickness structure, in which both ends are thinner and the center is thicker along the radial direction of the cooling flattened tube (1).

[0010] Furthermore, the traction base (2) is a rectangular platinum plate, and the connection method between the traction base (2) and the cooling flattened tube (1) employs a hot forging patch.

[Effects of the Invention]

[0017] The device for preventing collapse during the heating process of a platinum channel cooling flat tube according to the present invention provides the following beneficial effects. This invention features a dedicated tension structure designed for the upper surface of a cooling flat tube, which includes a tension bar. The tension bar aligns with the joint gap, its extended end protrudes from the joint gap between the two heater modules, and its end is connected to the heater module. This ensures the stability of the cross-sectional structure of the cooling flat tube during the heating process, solves the collapse problem through structural support technology, has a clear point of application, a direct effect, and prevents the cooling flat tube from deforming or collapsing during the heating process.

[0018] In the apparatus according to the present invention, the tension structure is attached to the main body mainly in the form of a radial hook welded to the base, with the other end hooked into a groove in the installed heater brick. This structure transmits the collapse reaction force of the flattened tube to the upper heater brick, preventing deformation of the flattened tube. As a suitable mounting method for this structure, the original fine slurry filling material can be changed to a powder material with a sintering temperature of approximately 1200°C, thereby avoiding the tension structure from being subjected to streamlined shear forces during the heating and expansion process. Furthermore, after the expansion is complete, the joint gaps between the heater bricks can be finally filled with powder to ensure basic sealing.

[0019] The tension bar of the present invention employs a radial distribution similar to that of a cooling flattened tube, protruding from the joint gap between two heater modules and suspending from the ends of the heater modules, thereby solving the problem of heater module protrusion. Furthermore, it can also solve the problem of shear force on the suspension bars caused by the expansion in the direction of platinum flow and the relative misalignment with the heat-resistant material.

[0020] In this invention, a tensile base is provided between the tension bar and the cooling flattened tube, which reduces the tension point of the tension structure and decreases the risk of localized tearing problems occurring during the process of applying force.

[0021] The traction base adopts a shape that is thin at both ends and thick in the center, which effectively eliminates stress concentration problems caused by local dimensional changes due to the thickness transition at both ends.

[0022] The horizontal through-groove structure realizes the suspension of the tension bar, enabling the tension bar to transmit the traction force from the internal platinum flat tube to the external heater brick. Also, by ensuring a width of more than 20% of the wall thickness of the traction arm between the front and rear heater bricks, the problems of internal and external force transmission and the sealing of the structure can be solved.

[0023] In the present invention, the direction of the tension bar is designed to be the same radial direction as the cross-section of the cooling flat tube, enabling it to withstand a certain relative displacement without generating significant shear stress at the root. Also, by ensuring that the load is not completely applied, the problem of local cracking can be avoided.

[0024] In the method of the present invention, a dedicated filling is performed for the joint gap where the tension bar 3 protrudes, and by filling with aluminum oxide fine powder having a particle size of 0.1 mm, the final sealing performance of the entire structure can be ensured.

[0025] The present invention can cope with the increasing platinum size and provides effective structural reliability for the design of a platinum passage structure with a larger drawing amount. This method is currently being implemented in the G8.5 project, and it has been confirmed that the number of thermocouple failures in the upper part of the cooling flat tube has significantly decreased and the structural strength of the cooling flat tube has been improved.

The embodiments shown in these drawings and their descriptions are for explaining the present invention and do not unduly limit the present invention.

It is clear that the embodiments described are only a selection of embodiments of the present invention, and not all embodiments. All other embodiments that those skilled in the art can obtain without creative work based on the embodiments of the present invention are also within the scope of the protection of the present invention.

[0029] Furthermore, terms such as "first," "second," etc., in the specification and claims of the present invention, as well as in the drawings, are used to distinguish similar subjects and do not represent a specific order or sequence. Where appropriate, these terms are interchangeable, and embodiments of the present invention may be carried out in an order different from that described or illustrated herein. In addition, the terms "includes" and "has" and their variations are intended to be non-exclusive inclusions, for example, a process, method, system, product, or apparatus that includes multiple steps or elements may include other steps or elements not explicitly listed, or other steps or elements specific to those processes, methods, products, or apparatus.

[0030] (Example 1) As shown in Figures 1, 2, and 5, the apparatus for preventing collapse during the heating process of a platinum channel cooling flat tube according to the present invention includes a tension structure, and a plurality of heater modules 4 are arranged on the outside of the cooling flat tube 1, with a coupling gap provided between each opposing heater module 4. The tension structure is arranged on the outer surface of the cooling flat tube 1 and includes a tension bar 3. The tension bar 3 overlaps with the position of the coupling gap, and the extended end (protruding end) of the tension bar 3 extends (protrudes) from the coupling gap, and this extended end is connected to the end of the heater module 4. The height of the tension bar 3 is equal to the distance between the cooling flat tube 1 and the heater module 4.

[0031] As shown in Figures 1 and 5, the tension structure further includes a traction base 2, which is connected to the upper surface of the cooling flattened tube 1.

[0032] The traction base 2 employs a variable thickness structure, specifically having a shape where both sides are thinner and the center is thicker along the radial direction of the cooling flat tube 1.

[0033] The traction base 2 is a rectangular platinum plate, and a hot forging patch is used for connection. For example, in the case of a rectangular platinum plate with an original thickness of 1.5 mm and a cooling flat tube 1 with a thickness of 1.0 mm, the hot forging patch involves bonding the 1.5 mm thick rectangular platinum plate to the upper surface of the cooling flat tube 1 and forging it at a high temperature to create a certain adhesion force between the edge of the rectangular platinum plate and the cooling flat tube 1. For the central region, which has a relatively large thickness, a small amount of welding rod is added to both the front and rear sides of the rectangular platinum plate to weld the rectangular platinum plate and the cooling flat tube 1 together.

[0034] Preferably, the dimensions of the traction base 2 are related to the size of the upper surface of the cooling flattened tube. For example, in the case of a cooling flattened tube 1 with a width of 600 mm to 700 mm, the width of the traction base 2 is usually about 100 mm, and the width of the traction base 2 in the glass flow direction is designed to be 50 mm to 80 mm.

[0035] As shown in Figures 3 and 4, the tension bar 3 includes a welded base 3-1, an extension arm 3-2, and a towing hook 3-3. The welded base 3-1 is fully welded to the towing base 2, and the extension arm 3-2 is installed in the joint gap. Additionally, a transverse channel groove structure 4-1 is provided on the upper surface of the end of the heater module 4, and the towing hook 3-3 is suspended from the transverse channel groove structure 4-1.

[0036] The width of the joint gap is 20% or more of the wall thickness of the extension arm 3-2, and the depth of the transverse channel groove structure 4-1 is 5 mm to 10 mm.

[0037] Preferably, the length of the extension arm 3-2 is 70 mm to 90 mm, the width of the extension arm 3-2 is greater than 15 mm, and the wall thickness of the extension arm 3-2 is greater than 1.0 mm.

[0038] Preferably, the towing hooks 3-3 adopt an arc-shaped hook or other transient shape, and it is sufficient that the ends mainly have a hook structure.

[0039] Preferably, the width of the transverse channel groove structure 4-1 is 5 mm.

[0040] The radial arrangement of the tension bars 3 is the same as the radial arrangement of the cross-section of the cooling flattened tube 1.

[0041] The material of tensile bar 3 is a platinum-rhodium alloy, with a rhodium content of 10% to 20%.

[0042] A packed bed 5 is provided between the cooling flattened tube 1 and the heater module 4.

[0043] Preferably, the tension structure is based on the current 3000mm-40mm length structure and is generally placed in five locations, but can be increased as needed and depending on the number of joint gaps of the heater bricks.

[0044] The present invention provides a method for preventing collapse of a cooling flat tube during the heating process (also referred to in the present invention as a method for preventing collapse of a platinum channel cooling flat tube during the heating process), which uses a device to prevent the collapse of a platinum channel cooling flat tube during the heating process. This method includes the following steps: First, the sections of the heater module 4 are assembled and the cooling flat tube 1 is filled with powder material. Preferably, the powder material is filled into the four directions (up, down, left, and right) of the cooling flat tube 1 using a long feed tank, and at the same time, the cooling flat tube 1 is vibrated using a vibrator. The amplitude of the vibration is less than 2 mm, and after filling is completed, the vibration is stopped and heating of the platinum channel is started. After the platinum channel reaches 1300°C, the joint gap into which the tension bar 3 protrudes is filled, and aluminum oxide fine powder with a particle size of 0.1 mm is used for filling.

[0045] This method solves the problem of insufficient fluidity of the powder material by replacing the conventional fine aluminum oxide slurry with aluminum oxide powder material and employing a method of filling it in stages in separate portions.

[0046] (Example 2) Regarding the device for preventing the collapse of a platinum channel cooling flat tube during the heating process according to the present invention, as shown in Figure 1, the connection method between the tension structure and the cooling flat tube 1 includes the cooling flat tube 1, the tension base 2, and the tension bar 3 when viewed from the cross-sectional direction. Considering the structural characteristics of the entire cooling section, namely the presence of a heater brick structure outside the cooling flat tube 1, as shown in Figure 2, the heater modules 4 outside the cooling flat tube 1 are connected in groups of multiple sets, and it is necessary to maintain the structural integrity of the heater itself, and since the internal heating wires are evenly distributed, it is not possible to drill a hole in the center of the brick to disrupt the arrangement of the heating wires. Therefore, the tension bar cannot be drilled into the main plane of the upper heater module 4 and protrude, and the arrangement of the tension bar 3 must be considered. In the prior art, there have been several proposals regarding the suspension reinforcement structure of the cooling flat tube 1, but none have been able to solve the problem of protrusion from the heater module 4, nor have they been able to solve the problem of shear stress on the suspension bar caused by the relative displacement between the platinum's flow direction expansion and the refractory material. The tension bar 3 of the present invention adopts the same radial arrangement as the cross-section of the cooling flattened tube 1, protrudes from the joint gap between the two heater modules 4, and can be suspended from the ends of the heater modules 4, thereby completely solving the above-mentioned problems.

[0047] Regarding the connection to the tension structure, since the point of application of tensile force is small, local tearing is likely to occur during the process of applying force. Therefore, when connecting to the cooling flat tube 1, it is advisable to avoid directly welding the tension bar 3 to the cooling flat tube 1 as much as possible. To effectively solve this problem, a tension base 2 is provided between the tension bar 3 and the cooling flat tube 1. To connect the tension base 2 to the cooling flat tube 1 and to avoid local stress concentration, a structural form with varying wall thickness is adopted for the tension base 2. As shown in Figure 1, in the cross-sectional direction, the tension base 2 adopts a form in which both ends are thin and the center is thick, which effectively eliminates the problem of stress concentration caused by local dimensional changes resulting from the abrupt change in thickness at both ends.

[0048] The connection method between the traction base 2 and the cooling flat tube 1 employs a hot forging patch method. Specifically, a 1.5 mm thick rectangular platinum plate is bonded to the upper surface of the 1.0 mm thick cooling flat tube 1 and forged at high temperature to create a certain adhesive force between the edges of the rectangular platinum plate and the cooling flat tube 1. In addition, for the thicker central portion, a small amount of welding rod is added to both the front and rear sides to ensure overall bonding between the traction base 2 and the upper surface of the cooling flat tube 1. Generally, different sizes of rectangular traction base 2 are selected according to the size of the upper surface of the cooling flat tube. For example, in the case of a cooling flat tube with a width of 600 mm to 700 mm, the width of the traction base 2 is usually about 100 mm, and by designing the width in the glass flow direction to 50 mm to 80 mm, the traction effect for this area can be ensured.

[0049] As shown in Figure 3, the specific structure of the tension bar 3 is divided into a welded base 3-1, an extension arm 3-2, and a traction hook 3-3. The welded base 3-1 of the tension structure is connected to the lower traction base 2 in the form of a full weld. As shown in Figure 4, the length of the extension arm 3-2 is related to the thickness of the internal filling layer 5 and the external heater module 4. The current standard filling thickness is 15 mm, and the thickness of the heater 4 is generally 50 mm to 70 mm, ensuring the basic structural strength of the refractory material. The width and thickness of the extension arm 3-2 determine the traction load capacity, and the traction load capacity is also related to the overall material of the tension bar 3. The cooling flat tube 1 is generally made of a platinum-rhodium alloy with a rhodium content of 5% to 10%, and the tension bar 3 is usually designed with a rhodium content of 10% to 20%. The higher the rhodium content, the greater the tensile strength of the material. In this material structure, if the width exceeds 15 mm and the wall thickness exceeds 1.0 mm, the load capacity requirements can be met. The towing hook 3-3 employs an arc-shaped hook, or may employ other transient shapes, as long as the end has a hook structure.

[0050] Regarding the structure of the tension bar 3, as shown in Figure 4, a transverse channel groove structure 4-1 with a width of 5 mm and a depth of 5 mm to 10 mm is provided on the upper surface of the contact (connection) part of the external heater brick module 4, and is used to suspend the tension bar 3. This structure enables the tension bar 3 to transmit tension from the internal platinum flat tube 1 to the external heater brick 4, and it is sufficient to ensure a width of 20% or more of the wall thickness of the tension extension arm 3-2 between the two front and rear heater bricks 4, effectively solving the transmission problem between the internal and external and the basic sealing problem of the structure.

[0051] The tension structures are arranged in appropriate quantities and densities based on the length range of the cooling flattened tube 1, and are positioned to coincide with the location of the coupling gaps of the upper heater module 4. In the current 3000mm to 40mm length structure, five locations are usually sufficient, and as shown in Figure 5, this can be increased as appropriate depending on the actual needs and the number of coupling gaps of the heater module 4.

[0052] The method for preventing collapse of a cooling flat tube during the heating process according to the present invention (also referred to in the present invention as a method for preventing collapse of a platinum channel cooling flat tube during the heating process) is mainly realized in a device for preventing the collapse of a platinum channel cooling flat tube during the heating process by strengthening the structure of the cooling flat tube using a tension structure provided on the upper surface of the cooling flat tube 1 and a corresponding mounting method.

[0053] The tension structure must consider the load problem during the heating process. In conventional designs, the packing layer 5 placed between the cooled flat tube 1 and the heater module 4 is generally filled using a fine slurry of aluminum oxide. This is mainly because the slurry has excellent fluidity and can uniformly encase the cooled flat tube 1. However, during the heating process after filling, this slurry gains a certain strength at approximately 700°C. At this point, the expansion of platinum is not yet complete, and there is a difference in the expansion coefficients of the cooled flat tube 1 and the external heater module 4, resulting in relative movement between them. Conventional designs of suspension bars cannot solve this problem, and in some cases, shear stress is generated between the suspension bar and the cooled flat tube 1, causing localized cracking. To avoid this problem, the present invention first positions the tension bar 3 in the same radial direction as the cross-section of the cooled flat tube 1, thereby withstanding a certain relative movement and preventing the generation of significant shear stress at the base. Furthermore, to completely avoid load, the conventional fine slurry of aluminum oxide is changed to aluminum oxide powder, and a method of filling in stages in sections is adopted, which solves the problem of powder fluidity. Specifically, the heating module is partially assembled, and powder is filled into the cooling flat tube in all four directions (up, down, left, and right) using a long supply tank, while simultaneously vibrating the cooling flat tube 1 using a vibrator. The amplitude of the vibration is less than 2 mm to ensure that the powder is filled sufficiently uniformly. Once filling is complete, the vibration is stopped and heating of the platinum channel is started. During the actual heating process, the powder remains unbound and has little effect on the free movement of the internal platinum and suspension structure. When the temperature reaches 1200°C, the expansion of the platinum structure is almost complete, and at that point the filler material is just sintered, forming an integrated structure between the cooling flat tube 1, the packed layer 5, and the heater module 4. Finally, special filling is performed in the joint gap where the tension bar 3 protrudes, using 0.1 mm particle size aluminum oxide fine powder to ensure the final sealing of the entire structure.

[0054] This invention can accommodate the ever-increasing size of platinum and provides effective structural reliability for designing channel structures with larger platinum extraction volumes. Currently, this technology has been implemented in the G8.5 project, and its effects are remarkable, with a significant reduction in the number of thermocouple failures at the top of the cooling section during the heating process and a substantial improvement in the structural strength of the cooling flattened tube.

[0055] Finally, the above embodiments illustrate the technical solutions of the present invention and do not limit its scope of protection. Although the present invention has been described in detail based on the above embodiments, those skilled in the art should understand that various changes, modifications, or equivalent substitutions are possible in specific ways of carrying out the present invention after reading this disclosure. All of these changes, modifications, or equivalent substitutions fall within the scope of protection of the claims of the present invention. [Explanation of symbols]
