Description

Technical Field

[0001] This utility model belongs to the technical field of glass manufacturing, and specifically relates to a platinum channel clarification section. Background Technology

[0002] In glass manufacturing processes, platinum channels are commonly used to guide molten glass from the glass furnace to the glass forming equipment. A platinum channel typically includes an inlet section, a refining section, a cooling section, a stirring section, and a feeding section. The inlet and feeding sections are used to introduce and remove molten glass, respectively. The refining section removes air bubbles and impurities from the molten glass through high-temperature refining, ensuring its purity and uniformity. The cooling section uses internal grids and other structures to homogenize and stabilize the flow of the molten glass.

[0003] In the production process of special glass (such as substrate glass and cover glass), the strength of the platinum channel decreases due to high temperatures when the molten glass passes through it, especially in the refining section. The decrease in strength is more pronounced when the required refining temperature is typically above 1600℃. Furthermore, to facilitate the removal of air bubbles in the molten glass, the molten glass does not completely fill the refining section. This leads to the collapse and tearing of the channel wall above the molten glass surface in the horizontally arranged refining section. This not only affects the transport and refining effect of the molten glass but can also cause blockage or even scrapping of the refining section in severe cases. Chinese patent CN109336366A discloses a platinum channel structure resistant to high-temperature deformation. This solution strengthens the structure by setting horizontal and vertical support plates on the platinum channel and using components such as crucibles and crucible covers. However, this method involves many components and a complex overall structure, making it difficult to implement. Therefore, there is a need to design a platinum channel refining section that is resistant to high-temperature deformation and has a simple and reliable structure. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a platinum channel clarification section, which solves the technical problem that the structural strength of the existing platinum channel clarification section is not good enough to meet the requirements of high-temperature clarification, and achieves the effect of improving the strength of the clarification section and ensuring smooth clarification.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A platinum channel clarification section includes a tubular clarification section body, with an inner reinforcing rib on the top of the inner wall of the clarification section body. The inner reinforcing rib extends circumferentially on the inner wall of the clarification section body, and there are multiple inner reinforcing ribs that are spaced apart along the axial direction of the clarification section body.

[0007] Furthermore, there is a gap between the lowest point of the inner reinforcing rib and the bottom of the inner wall of the clarifying section body to prevent the inner reinforcing rib from being submerged in the glass melt.

[0008] Furthermore, the inner reinforcing rib has an axially penetrating vent hole at the top of the inner wall near the clarification section body. The vent hole is connected to the exhaust channel above the liquid surface in the clarification section to realize the exhaust function.

[0009] Furthermore, the two ends of the clarification section body are respectively connected to support flanges, and the top of the outer wall of the clarification section body is provided with a first outer reinforcing rib. The first outer reinforcing rib extends along the axial direction of the clarification section body, and the end of the first outer reinforcing rib is spaced apart from the corresponding support flange.

[0010] Furthermore, the first outer reinforcing rib includes a long strip-shaped connecting part and a reinforcing part. The length direction of the connecting part and the reinforcing part corresponds to the axial direction of the clarification section body. The plate surface of the connecting part is vertical, the lower end is connected to the top of the outer wall of the clarification section body, and the upper end is connected to the reinforcing part. The reinforcing part is arranged to extend laterally or inclined upward.

[0011] Furthermore, a second outer reinforcing rib is provided at the bottom of the outer wall of the clarification section body. The second outer reinforcing rib extends circumferentially on the outer wall of the clarification section body, and the two ends of the second outer reinforcing rib are spaced apart from the first outer reinforcing rib.

[0012] Furthermore, the second outer reinforcing rib is located in the axial middle of the clarifying section body.

[0013] Furthermore, the clarification section body has axial folds, and there are multiple axial folds that are distributed at intervals along the axial direction of the clarification section body.

[0014] Furthermore, axial folds form annular protrusions on the inner wall of the clarifying section body.

[0015] Furthermore, along the axial direction of the clarified section body, axial folds and internal reinforcing ribs are alternately distributed.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The platinum channel clarification section of this utility model strengthens the structural strength of the top of the clarification section body by setting circumferentially extending inner reinforcing ribs on the top of the inner wall of the clarification section body, thereby improving the high-temperature deformation resistance of the platinum channel clarification section and preventing the tube wall above the liquid surface from collapsing or tearing. This allows the platinum channel clarification section to smoothly complete the task of transporting and clarifying glass melt at high temperatures, effectively solving the problem that the structural strength of existing platinum channel clarification sections is insufficient to meet the requirements of high-temperature clarification, and is conducive to ensuring the high-temperature clarification effect and improving the stability of glass production.

[0018] 2. The platinum channel clarification section of this utility model, by providing a first outer reinforcing rib along the axial direction at the top of the outer wall of the clarification section body and providing a second outer reinforcing rib extending circumferentially from the bottom to the top on the outer wall of the clarification section body, not only improves the ability of the platinum channel clarification section to resist axial deformation and circumferential deformation, but also the first outer reinforcing rib, the second outer reinforcing rib and the inner reinforcing rib work together to further strengthen the structural strength of the clarification section body and improve the ability of the platinum channel clarification section to resist high temperature deformation.

[0019] 3. The platinum channel refining section of this utility model has axial wrinkles formed on the refining section body, which not only further enhances the structural strength of the refining section body, but also has a buffering and releasing effect on high-temperature shear and expansion forces within a certain range, which can effectively reduce cracking and deformation caused by expansion and contraction due to temperature changes; in addition, the axial wrinkles form annular protrusions inside the refining section body, which can change the flow direction of the glass melt inside the refining section body, which is not only conducive to homogenizing the glass melt, but also conducive to the discharge of air bubbles from the glass melt, thus improving the glass quality.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] Example 1:

[0028] Please see Figure 2 and Figure 3A platinum channel clarification section includes a tubular clarification section body 1. The top of the inner wall of the clarification section body 1 is provided with an inner reinforcing rib 2. The inner reinforcing rib 2 extends circumferentially on the inner wall of the clarification section body 1. There are multiple inner reinforcing ribs 2 and they are distributed at intervals along the axial direction of the clarification section body 1.

[0029] The platinum channel clarification section of this invention strengthens the structural strength of the top of the clarification section body 1 by setting circumferentially extending inner reinforcing ribs 2 on the top of the inner wall of the clarification section body 1, thereby improving the high-temperature deformation resistance of the platinum channel clarification section. This prevents the tube wall above the liquid surface from collapsing or tearing, allowing the platinum channel clarification section to smoothly complete the task of transporting and clarifying high-temperature glass liquid. It effectively solves the problem that the structural strength of existing platinum channel clarification sections is insufficient to meet the high-temperature clarification requirements, which is beneficial to ensuring the high-temperature clarification effect and improving the stability of glass production.

[0030] Please see Figure 2 and Figure 3 The lowest point of the inner reinforcing rib 2 is spaced from the bottom of the inner wall of the clarifying section body 1 to prevent the inner reinforcing rib 2 from being submerged in the glass melt; in this embodiment, the inner reinforcing rib 2 is a fan-shaped ring obtained by concentrically cutting a circular ring.

[0031] Thus, since the refining section, primarily the portion of the pipe wall above the molten glass surface, is prone to collapse and tearing, the internal reinforcing rib 2 is designed to exist only at the top of the refining section body 1, while still meeting structural strength requirements. This not only reduces the amount of platinum material used and saves costs, but also helps control the weight of the refining section and further improves structural stability. Furthermore, it prevents the internal reinforcing rib 2 from being submerged in the molten glass, reducing raw material contamination caused by platinum material evaporation into the molten glass. In implementation, the internal reinforcing rib 2 can be segmented or annular. The distance between the internal reinforcing rib 2 and the bottom of the inner wall of the refining section body 1 is determined based on the highest liquid level of the molten glass inside the refining section body 1 under actual operating conditions. This distance should be greater than the value corresponding to the highest liquid level. Figure 3 As shown, the lowest point of the inner reinforcing rib 2 is higher than the liquid level line 10 to ensure that the inner reinforcing rib 2 will not be submerged in the molten glass.

[0032] Please see Figure 3 The inner reinforcing rib 2 has an axially penetrating vent hole 3 on the top of the inner wall near the clarification section body 1. The vent hole 3 is connected to the exhaust channel above the liquid surface in the clarification section to realize the exhaust function. In this embodiment, the vent hole 3 is circular.

[0033] Thus, with multiple inner reinforcing ribs 2 spaced axially at the top of the inner wall of the clarifying section body 1, when the glass melt level in the clarifying section body 1 is high, the inner reinforcing ribs 2 will block the exhaust channel formed between the inner wall of the clarifying section body 1 and the glass melt, thereby affecting the smooth exhaust of the platinum channel clarifying section. Therefore, this utility model provides a vent hole 3 through the inner reinforcing rib 2 near the top. The spaces on both sides of the inner reinforcing rib 2 can be connected through the vent hole 3, so that the exhaust channel between the inner wall of the clarifying section body 1 and the glass melt still has good axial connectivity when the glass melt level is high, thereby avoiding affecting the high-temperature clarification and bubble removal functions of the clarifying section body 1.

[0034] Please see Figure 1 and Figure 2 The top of the outer wall of the clarification section body 1 is provided with a first outer reinforcing rib 5. The first outer reinforcing rib 5 extends along the axial direction of the clarification section body 1. Support flanges 4 are connected to both ends of the clarification section body 1 respectively. The end of the first outer reinforcing rib 5 is spaced apart from the support flange 4 at the corresponding end.

[0035] Thus, by setting the first outer reinforcing rib 5 axially at the top of the outer wall of the clarifying section body 1, not only is the axial deformation resistance of the platinum channel clarifying section improved, but also, in conjunction with the inner reinforcing rib 2, the structural strength of the top of the clarifying section body 1 is further strengthened, improving the high-temperature deformation resistance of the platinum channel clarifying section. This helps to prevent the pipe wall at the top of the clarifying section body 1 above the liquid surface from collapsing or tearing, allowing the platinum channel clarifying section to successfully complete the task of transporting and clarifying the glass melt at high temperatures. The support flange 4 is an inherent structure of the platinum channel clarifying section. The support flange 4 is not only used to support the clarifying section body 1, but also to connect the wires to energize the clarifying section body 1. The end of the first outer reinforcing rib 5 is kept at a distance from the support flange 4 to prevent the first outer reinforcing rib 5 from directly conducting to the support flanges 4 at both ends, thereby affecting the clarification effect provided by the energized heating of the clarifying section body 1.

[0036] Please see Figure 3 The first outer reinforcing rib 5 includes a long strip-shaped connecting part 6 and a reinforcing part 7. The length direction of the connecting part 6 and the reinforcing part 7 is corresponding to the axial direction of the clarifying section body 1. The plate surface of the connecting part 6 is vertical. The lower end of the connecting part 6 is connected to the top of the outer wall of the clarifying section body 1. That is, in the vertical direction, the height of the lower end of the connecting part 6 is equal to the maximum radial height of the clarifying section body 1. The upper end of the connecting part 6 is connected to the reinforcing part 7. The reinforcing part 7 is arranged to extend laterally or inclined upward. In this embodiment, the cross-section of the first outer reinforcing rib 5 is T-shaped.

[0037] In this way, the first outer reinforcing rib 5 is connected to the clarifying section body 1 through the connecting part 6, and the structural strength of the connecting part 6 is strengthened by the reinforcing part 7 which is at a certain angle to the connecting part 6. This not only reduces the amount of material used, saves costs and reduces the weight, but also has better resistance to axial deformation than directly setting the arc-shaped stiffening plate on the clarifying section body 1 with the connecting surface matching the top of the outer wall. This is beneficial to improving the structural strength of the clarifying section body 1.

[0038] Please see Figure 1 and Figure 3 The bottom of the outer wall of the clarification section body 1 is provided with a second outer reinforcing rib 8. The second outer reinforcing rib 8 extends circumferentially on the outer wall of the clarification section body 1, and the two ends of the second outer reinforcing rib 8 are spaced apart from the first outer reinforcing rib 5.

[0039] In this way, the second outer reinforcing rib 8 extends circumferentially from bottom to top on the outer wall of the clarification section body 1. The two ends of the second outer reinforcing rib 8 are close to the top of the clarification section body 1 and maintain a certain distance from the first outer reinforcing rib 5. If they are in contact without maintaining a distance, current circulation will be generated, which will reduce the heating capacity of the equipment and generate a disordered electromagnetic field. The second outer reinforcing rib 8 strengthens the tube wall of the clarification section body 1 except for the top. Together with the first outer reinforcing rib 5 and the inner reinforcing rib 2, it further improves the overall structural strength of the platinum channel clarification section.

[0040] Please see Figure 1 The second outer reinforcing rib 8 is located in the axial middle of the body 1 of the clarifying section.

[0041] Thus, given that the clarification section body 1 already has an inner reinforcing rib 2 spaced along the axial direction inside and a first outer reinforcing rib 5 on the outside, setting a second outer reinforcing rib 8 only in the middle of the axial direction of the clarification section body 1 not only effectively compensates for the insufficient strength of the middle of the entire pipe wall of the clarification section body 1, but also reduces the amount of material used, saves costs and reduces its weight.

[0042] Please see Figure 1 and Figure 2 The clarifying section body 1 has axial folds 9, and there are multiple axial folds 9 distributed at intervals along the axial direction of the clarifying section body 1. In practice, the axial folds 9 can be obtained by radially extruding and extending the clarifying section body 1 with a mold, or by axially extruding the clarifying section body 1. Its structure is similar to an expansion joint.

[0043] Thus, the clarifying section body 1 with axial folds 9 in the tube wall can not only enhance the structural strength of the clarifying section body 1, but also buffer and release high temperature shear and expansion forces within a certain range. It can effectively reduce cracking and deformation caused by expansion and contraction due to temperature changes. Combined with various reinforcing ribs, it is beneficial to further improve the structural stability of the platinum channel clarifying section.

[0044] Please see Figure 2 Axial folds 9 form annular protrusions on the inner wall of the clarifying section body 1.

[0045] In this way, the axial wrinkles 9 form annular grooves on the outside of the refining section body 1 and corresponding annular protrusions on the inside. The annular protrusions change the flow direction of the glass melt in the refining section body 1, which not only helps to homogenize the glass melt and improve glass stripe defects, but also helps to remove air bubbles from the glass melt and improve glass quality. Thus, the axial wrinkles 9 can not only enhance structural stability and extend service life, but also improve the quality of glass melt and ensure the continuity and stability of glass production.

[0046] Please see Figure 2 Along the axial direction of the clarified section body 1, axial folds 9 and inner reinforcing ribs 2 are alternately distributed.

[0047] In this way, the axial folds 9 and the inner reinforcing ribs 2 are alternately distributed in the axial direction, which not only makes the manufacturing difficulty relatively low, but also makes the reinforcing effect of the axial folds 9 and the inner reinforcing ribs 2 on the clarifying section body 1 more uniform, so that the clarifying section body 1 has better structural stability.

[0048] Example 2:

[0049] Please see Figure 4 The difference from Embodiment 1 is that in this embodiment, the inner reinforcing rib 2 is in the shape of a ring cut by a straight line, the vent 3 is in the shape of a semi-circular notch, and the cross-section of the first outer reinforcing rib 5 is Y-shaped.

[0050] Example 3:

[0051] Please see Figure 5 The difference from Embodiment 1 is that in this embodiment, the inner reinforcing rib 2 is a small circle obtained by cutting a circle with a straight line, the vent 3 is a transverse elongated hole, and the cross-section of the first outer reinforcing rib 5 is L-shaped.

[0052] In the platinum channel clarification section of this utility model, the supporting flange 4 is welded to both ends of the clarification section body 1 to provide support force and generate heat effect through energization to complete high-temperature clarification; the first outer reinforcing rib 5 is attached and welded to the top of the outer wall of the clarification section body 1 and extends axially to reduce the overall downward bending of the clarification section body 1; the inner reinforcing rib 2 is attached and welded to the top of the inner wall of the clarification section body 1 and extends circumferentially to prevent the top of the clarification section body 1 from collapsing downward; the second outer reinforcing rib 8 is attached and welded to the outer wall of the clarification section body 1 and extends circumferentially to prevent circumferential deformation of the clarification section body 1.

[0053] To further illustrate the structural advantages of the platinum channel refining section described in this utility model, the following analysis is conducted: In conventional platinum channel refining sections, the torque generated by the load G is balanced with the supporting torque generated by the structural deformation of the refining section, i.e., M = F. G *L G =F1*L1, where F G The pressure generated by the load, L G F1 is the force generated by the deformation of the refining section, and L1 is the force arm of the pipe wall in the refining section.

[0054] Assume the force at which the clarifying section undergoes destructive deformation is F1. ′ Then it is necessary to make F1 < F1 ′ To ensure the clarification segment remains intact, the optimization design strategy is to reduce the F1 value, as shown in the formula M = F. G *L G In the expression F1*L1, if we want to decrease the value of F1, we can choose to decrease F. G Value, decrease L G Value and increase L1 value;

[0055] To address this, the platinum channel clarification section of this invention features a first external reinforcing rib axially arranged at the top of the outer wall of the clarification section body to provide support and reduce the load F. G The first outer reinforcing rib is located between the two supporting flanges, which also reduces the load arm L. G Furthermore, the clarification section body, through the combination of its inner reinforcing ribs, second outer reinforcing ribs, and axial folds with the supporting flange, changes the stress on the clarification section body from a plate-like structure to a T-shaped structure, increasing the lever arm L1 value of the clarification section body wall. Therefore, this utility model, through optimized structural design, reduces the force of deformation of the platinum channel clarification section, effectively reducing the risk of rupture and damage to the platinum channel clarification section.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
