Description

Technical Field

[0001] The present invention belongs to the field of substrate glass manufacturing technology, and specifically relates to a high-efficiency supply device and method for the flange base in the fining section of a platinum channel in a thermal state.

Background Art

[0002] The platinum channel is a core device in the substrate glass manufacturing process, and it is necessary to perform step-by-step support operation based on various operation scenarios and the final equipment operation requirements at different stages, such as design, manufacturing, installation of stone materials, and pipe management of temperature expansion. The fining section has the highest operating temperature within the platinum channel structure and is a very fragile component. Since the platinum channel is mainly made of platinum-rhodium alloy material, it has excellent high-temperature resistance and corrosion resistance, but long-term operation exceeding 1400°C and continuous erosion and corrosion by the internal glass liquid are still very difficult for the platinum matrix itself.

[0003] In the initial installation process of the platinum channel, most areas of the fining section can be sealed under room temperature conditions. This sealing method mainly uses high-temperature-resistant zirconium powder to seal and supply the space between the outside of the platinum and the refractory bricks. On the other hand, for the flange area of the platinum channel, relative expansion movement occurs between the platinum and the refractory material during the actual heating process, and since the size of the flange itself is larger than that of the refractory brick, it is necessary to reserve space in the flange area of the fining section in advance. After the heating expansion is completed, supply is carried out rapidly at high temperature to ensure the final sealing effect of the flange base.

[0004] Judging from years of line body analysis, the main issue limiting the lifespan of platinum channels is the flange base region of the clearing section. Although this region is eventually supplied in a thermal state, the harsh operating environment, confined space, and demanding technical requirements for operators at high temperatures still result in a disparity compared to the room-temperature supply in the clearing main section. Overall analysis shows that the density of thermal supply at the flange base only reaches about 70% of the platinum supply of the main section. Therefore, in actual production, partial cracking first occurs in the flange base region when the channel has been in operation for more than two years. This is due to oxidation at high temperatures, which causes excessive volatilization of the matrix material, ultimately leading to a significant thinning of the tube body wall thickness, and with further deterioration, the platinum tube body eventually ruptures in that region. This rupture depends not only on the reduction in wall thickness but is also accelerated by localized Joule heating caused by the operating current. [Overview of the project] [Problems that the invention aims to solve]

[0005] Based on the above, a more convenient auxiliary method needs to be considered for sealing the flange base of the clearing section. Conventional supply methods mainly involve multiple people simultaneously supplying from different angles using simple shovels, which is highly inefficient and has low supply effectiveness. Furthermore, it is necessary to remove the temporary insulation material in this area during the supply process, exposing the platinum, and the longer the time, the greater the temperature difference, negatively impacting subsequent heating and commissioning. Therefore, improving supply efficiency is the main objective in this area.

[0006] Therefore, it is necessary to solve the problem of the long working time required for sealing and supplying the flange base of the clarifying section of conventional platinum channels.

[0007] In other words, there is a problem with conventional platinum channels: the sealing and supply process at the flange base of the clarifying section takes a long time. [Means for solving the problem]

[Effects of the Invention]

[0019] The present invention offers the following beneficial effects.

[0020] The supply structure of this invention penetrates the supply observation port, with the output end of the supply structure installed in the cavity region and the input end of the supply structure installed outside the refractory brick channel. By converting internal supply to simple external supply and achieving rapid supply, it provides a time advantage that is effective for heat retention in the flange base region of the cleared section of the platinum channel, effectively improving the density of thermal state supply at the flange base, shortening working time, and saving both time and economic costs. This gives it high utility value.

[0021] The supply structure of the present invention allows for the rapid construction of a supply trough by designing a non-standard stainless steel supply pipe and a supply support frame with a simple fixed structure, and provides a rapid supply function as the supply nozzle extends directly into the supply gap.

[0022] This invention employs a method of synchronous supply using a common supply trough with one or three supply structures, thereby effectively improving supply efficiency and avoiding local supply blind spots.

[0023] The supply trough of the present invention adopts a hopper structure with a large upper part and a small lower part. Since the inclination angle of the side supply trough is set from 75° to 80°, the material powder can slide into the supply pipe, ensuring the normal flow of the material powder and preventing deposition. Furthermore, since the inclination angle is less than 80°, the problem of dust of the material powder can be avoided.

[0024] The side supply pipe of the present invention has an overall diagonal design, ensuring that the side supply trough does not contact the refractory brick channel of the channel body, and at the same time, the material powder can be supplied from the outside to the inside of the flange base.

[0025] The cross-section of the supply pipe of the present invention is designed as a rounded rectangle or an ellipse, ensuring the consistency of the sizes of the supply pipe and the supply nozzle. The narrow direction is vertically distributed. When inserting into the supply gap of the flange base, the space is narrow, so the supply pipe is arranged vertically, and the narrow side of the cross-sectional rounded rectangle coincides with the narrow side of the supply gap, so that the supply pipe can smoothly enter the narrow flange base cavity.

[0026] The end of the supply nozzle of the present invention is designed in an inclined shape or a rectangle, which is suitable for further inserting a small amount of material powder deeper.

[0027] The upper part of the support frame of the present invention is connected to the connection ears and bolts welded to the supply trough and the supply pipe, and can rotate at a certain angle around the connection point. Thereby, the span angle of the support frame can be adjusted, and it has a certain rotation and adjustment function.

[0028] A circular support leg is welded to the bottom of the support frame of the present invention, which can ensure a certain anti-slip function

[0029] The angle of the upper supply pipe of the present invention is designed to be smaller than the angle of the side supply pipe, which can avoid the dust problem caused by the large height difference in the upper part.

[0030] The supply structure of the present invention is made of stainless steel material with a carbon content of less than 0.08%, so that metal tools do not cause contamination of the internal platinum body and carbonization reactions at high temperatures can be avoided.

[0031] In the heating process of this invention, the cavity region is temporarily sealed using high-temperature cotton (high-temperature cotton) to ensure a certain heat retention effect without affecting the expansion of platinum, and the temperature difference in the cavity region inside the platinum is kept below 100°C. With this invention, the entire pot of supply material can be injected into the supply structure at once, and the supply material automatically enters the flange base, thus optimizing the conventional supply method of gradually adding small amounts in stages. In actual operation, using this invention, the supply to the flange base can be completed within 10 minutes, and the speed can be improved by approximately 70% compared to the conventional method of holding the material tub by hand and pouring the material multiple times with a shovel.

[0036] (Example 1) The present invention provides a highly efficient supply device for the thermal state at the flange base of the clarifying section of a platinum channel, and includes a supply structure. A refractory brick channel 4 is installed outside the clarifying section of the platinum channel. The clarifying section of the platinum channel includes a platinum body 1 and a flange 2. A cavity region is provided between the flange 2 and the refractory brick channel 4, which is to allow the flange 2 to expand normally during the heating process. A supply observation port is provided in the refractory brick channel 4 corresponding to the cavity region, and the transfer end of the flange 2 passes through the supply observation port. The supply structure also passes through the supply observation port, the output end of the supply structure is installed in the cavity region, the input end of the supply structure is located outside the refractory brick channel 4, and a pre-retention distance is provided between the output end of the supply structure and the platinum body 1.

[0037] The supply structure of the present invention penetrates the supply observation port, with the output end of the supply structure set in the cavity region and the input end of the supply structure set outside the refractory brick channel. By converting internal supply to external simplified supply, rapid supply is achieved, providing a time advantage that is effective for heat retention of the flange base region of the clarified section of the platinum channel. This improves the density of thermal state supply at the flange base, reduces working time, saves time and economic costs, and results in high utility value.

[0038] The above supply structure includes a side supply structure 7, and two side supply structures 7 are provided, with the two side supply structures 7 arranged symmetrically on both sides of the platinum channel.

[0039] The side supply structure 7 includes a side supply trough 7-1, a side supply pipe 7-2, a side supply nozzle 7-3, and a side supply support frame 7-4. The side supply trough 7-1 employs a hopper structure with a larger upper section and a smaller lower section, and the inclination angle of the hopper structure is set to 75° to 80°. Connecting ears are welded to the outside of the side supply trough 7-1 and the side supply pipe 7-2. The side supply support frame 7-4 includes an upper long leg and an upper short leg on the side; the upper short leg is located at the outer near end of the refractory brick channel 4, and the upper long leg is located at the outer far end of the refractory brick channel 4. The top of the side supply support frame 7-4 is connected to connecting ears with bolts, and side support legs are welded to the bottom of the side supply support frame 7-4.

[0040] The side support legs are circular, and the side supply pipe 7-2 and side supply nozzle 7-3 are designed as inclined multi-angle connecting pipes or inclined multi-curve connecting arc multi-stage connecting pipes. Furthermore, the cross-sections of the side supply pipe 7-2 and side supply nozzle 7-3 are circular-rectangular or elliptical, and these cross-sections are positioned perpendicular to the direction of flow of the supplied material. The outlet end of the side supply nozzle 7-3 is designed to be angled or rectangular.

[0041] The supply structure of the present invention allows for the rapid construction of a supply trough by designing a specially shaped stainless steel supply pipe and a supply support frame with a simple fixed structure, and the supply nozzle can extend directly into the supply gap, providing a rapid supply function.

[0042] This invention employs a method of synchronous supply by adding one or three supply structures to a common trough, thereby effectively improving supply efficiency and avoiding local supply blind spots.

[0043] The supply trough employs a hopper structure with a larger upper section and a smaller lower section. The inclination angle of the side supply trough is set to 75° to 80°, allowing the material powder to slide into the supply pipe, maintaining normal flow while preventing accumulation. Furthermore, an inclination angle of less than 80° helps to suppress the problem of dust from the raw material powder.

[0044] The side supply pipe according to the present invention employs an overall angled design, which prevents the side supply trough from contacting the refractory brick channel of the channel body, while simultaneously allowing material powder to be transferred from the outside to the inside of the flange base.

[0045] The cross-section of the supply pipe of the present invention is designed to be a circular rectangle or an ellipse, ensuring dimensional consistency between the supply pipe and the supply nozzle. When the relatively narrow width direction is vertically distributed and inserted into the supply gap at the flange base, the side supply pipe 7-2 must be positioned vertically due to the narrow space. In other words, the narrow side of the circular rectangle cross-section matches the narrow side of the supply gap, ensuring that the supply pipe smoothly enters the narrow cavity at the flange base.

[0046] The supply structure further includes an upper supply structure 8, and the supply observation port includes a side opening 5 and an upper opening 6. The side supply structure 7 passes through the side opening 5, the upper supply device 8 passes through the upper opening 6, and the transfer end of the flange 2 passes through the upper opening 6.

[0047] The upper supply structure 8 includes an upper supply trough 8-1, an upper supply pipe 8-2, an upper supply nozzle 8-3, and an upper supply The upper supply trough 8-1, including the support frame 8-4, employs a hopper structure with a larger upper section and a smaller lower section. Connecting ears are welded to the upper supply trough 8-1 and the upper supply pipe 8-2. The upper supply support frame 8-4 includes an upper long leg section and an upper short leg section, with the upper short leg section installed at the outer near end of the refractory brick channel 4 and the upper long leg section installed at the outer far end. The upper part of the upper supply support frame 8-4 is connected to the connecting ears with bolts, and upper support legs are welded to the bottom of the upper supply support frame 8-4.

[0048] The upper support legs are circular, and the upper supply pipe 8-2 and upper supply nozzle 8-3 are designed as straight sections or segmented multi-angled connecting pipes. The cross-sections of the upper supply pipe 8-2 and upper supply nozzle 8-3 are circular-rectangular or elliptical, and the outlet end of the upper supply nozzle 8-3 is designed to be beveled or rectangular.

[0049] The supply pipe cross-section of this invention is designed to be circular-rectangular or elliptical, ensuring dimensional consistency between the supply pipe and the supply nozzle. The narrow width direction is used as vertical distribution, allowing the supply pipe to smoothly enter the cavity of the narrow flange base.

[0050] The end of the supply nozzle is designed to be angled or rectangular, facilitating the further advancement of small amounts of material powder into the nozzle.

[0051] The upper part of the support frame of the present invention is connected to the supply trough and supply pipe by connecting ears and bolts welded to them, and is capable of rotating by a certain angle around the connection point, i.e., the straddle angle of the support frame can be adjusted, thus providing a degree of rotation and adjustment capability.

[0052] In this invention, circular support legs are welded to the bottom of the support frame, ensuring a certain level of anti-slip function.

[0053] The cross-sectional width of the upper supply pipe 8-2 is equal to the cross-sectional width of the side supply pipe 7-2, the cross-sectional length of the upper supply pipe 8-2 is greater than the cross-sectional length of the side supply pipe 7-2, and the inclination angle of the upper supply pipe 8-2 is greater than the inclination angle of the side supply pipe 7-2. In addition, the volume of the upper supply trough 8-1 is greater than the volume of the side supply trough 7-1. The angle of the upper supply pipe according to the present invention is designed to be smaller than the angle of the side supply pipe, thereby avoiding dust problems caused by the high drop at the top.

[0054] A supply layer 3 is provided between the aluminum body 1 and the refractory brick channel 4. The supply layer is made of stainless steel with a carbon content of less than 0.08%. This prevents metal tools from contaminating the internal aluminum body and prevents carbonization reactions at high temperatures.

[0055] The present invention provides a highly efficient supply method for the platinum channel clarifying section flange base in a thermal state, utilizing a highly efficient supply device for the platinum channel clarifying section flange base in a thermal state, and includes the following steps. First (Step 1), the cavity region between the flange 2 and the refractory brick channel 4 is temporarily sealed with high-temperature cotton during the heating process. Once it is confirmed that the expansion of the platinum channel clarifying section has reached a predetermined value, the insulating cotton is removed from the cavity region, and the supply structure is quickly inserted into the platinum channel clarifying section flange base through the supply observation port, providing a pre-retention distance between the output end of the supply structure and the platinum body 1. In Step 2, the supply material is fed into the input end of the supply structure, and the supply material flows into the platinum channel clarifying section flange base through the supply structure. The supply status of the supply material is observed through the supply observation port, completing the highly efficient supply of the platinum channel clarifying section flange base in a thermal state.

[0056] In the heating process according to the present invention, temporarily sealing the cavity region with high-temperature cotton prevents the expansion of platinum from being affected and maintains a constant heat retention effect. This makes it possible to keep the temperature difference in the cavity region inside the platinum below 100°C. Furthermore, in the present invention, since all the supply material in the container can be put into the supply structure at once, the supply material automatically enters the flange base, and the conventional supply method, which adds the supply material little by little gradually, can be optimized.

[0057] (Example 2) As shown in Figure 1, the clarification section structure is a mature structure conventionally used in platinum channels, and the prior art clarification section flange structure is the main structure in the high-temperature range of platinum channels. This structure primarily serves to perform high-temperature clarification and bubble removal of the initial molten glass from the pond furnace, thereby purifying the glass melt. The clarification section structure includes two main components: a platinum body 1 and a flange 2. The flange 2 is mainly used to supply current, and two flanges 2 form a set of circuits, converting the current into Joule heat in the platinum body 1 itself, thereby achieving the objective of heating the glass liquid inside.

[0058] As shown in Figures 2 and 3, the high-efficiency supply device for the flange base of the platinum channel clarification section according to the present invention has a multi-layer refractory material structure encased on the outside of the clarification section, collectively referred to as a refractory brick. Between the platinum body 1 and the refractory brick channel 4 is the main supply layer 3, which provides normal supply at room temperature. To ensure the normal function of the protruding flange 2, a cavity region of a certain length is pre-defined within this region of the refractory brick channel 4, which functions as space for the normal expansion of the flange 2. Three supply observation openings are provided on the outside of this cavity region of the flange 2, which are divided into a side opening 5 and an upper opening 6.

[0059] As shown in Figure 3, the supply structure consists of two parts: a side supply structure 7 and an upper supply structure 8. There are two side supply structures 7, symmetrically arranged on both sides of the channel, and only one upper supply structure 8 is needed, for a total of three. The supply structure is attached to the two side openings 5 ​​and the upper opening 6 by a fixed support frame, and the actual supply process is carried out through these three openings, ensuring that the supply reaches every corner of the internal cavity.

[0060] The entire supply structure is made of stainless steel, and the carbon content of the stainless steel is less than 0.08%, which prevents metal tools from contaminating the internal platinum body and avoids carbonization reactions at high temperatures.

[0061] As shown in Figure 4, the side supply structure 7 includes four parts: a side supply trough 7-1, a side supply pipe 7-2, a side supply nozzle 7-3, and a side supply support frame 7-4. The side supply trough 7-1 employs a conventional hopper structure with a large upper section and a small lower section, which allows the material powder to slide into the side supply pipe 7-2. The inclination angle of the side supply trough 7-1 is 75° to 80°. Repeated measurements of the fluidity test of the base material powder have confirmed that an inclination angle of 75° to 80° ensures normal flow of the material powder and prevents accumulation. An inclination angle of less than 80° can avoid the problem of the material powder scattering. Preferably, depending on the single-person loading capacity of the supply operator and the compressed density of the material powder, the volume of the side supply trough 7-1 is 0.3 m³. 3 That is the case.

[0062] The side supply pipe 7-2 employs an overall angled design, which prevents the side supply trough 7-1 from contacting the refractory brick channel 4, ensuring that material powder can be reliably delivered from the outside into the lumen at the flange base. The angle and length of the side supply pipe 7-2 are designed according to the size of the supply trough 7-1 and the outer dimensions (outer contour) of the channel refractory brick 4. Considering the fluidity of the material, the side supply pipe 7-2 can employ angled multi-angle connecting pipes or angled multi-curve connecting arc multi-stage connecting pipes. The cross-section of the side supply pipe 7-2 is a rounded rectangular structure, ensuring size consistency between the side supply pipe 7-2 and the side supply nozzle 7-3, with a relatively narrow width distributed vertically. Due to the limited space when inserting it into the supply gap at the base of the lunge, the side supply pipe 7-2 needs to be positioned vertically. In other words, the narrow side of the rounded rectangular cross-section coincides with the narrow side of the supply gap, allowing the side supply pipe 7-2 to smoothly enter the narrow flange base cavity. Preferably, the cross-sectional width of the side supply pipe 7-2 is 25 mm, and the length and area of ​​the cross-section are designed based on the flow rate and fluidity, with the cross-sectional length of the side supply pipe 7-2 being 50 mm to 70 mm.

[0063] The side supply nozzle 7-3 has the same structure as the side supply pipe 7-2, and the end of the side supply nozzle 7-3 is designed to be beveled (chamfered) or rectangular, making it easier for small amounts of material powder to enter.

[0064] The side supply support frame 7-4 includes a long side upper leg and a short side upper leg, with the long side upper leg positioned outward and the short side upper leg positioned inward. The upper part of the side supply support frame 7-4 is connected to the side supply trough 7-1 and the side supply pipe 7-2 by connecting ears and bolts welded to them, allowing it to rotate at a certain angle around the connection point. That is, the span angle of the support frame is adjustable, providing rotation and adjustment functions, and circular side support legs are welded to the bottom of the side supply support frame 7-4 to ensure a certain anti-slip function.

[0065] As shown in Figure 5, the upper supply structure 8 is similar to the side supply structure 7, and the upper supply structure 8 consists of an upper supply trough 8-1, an upper supply pipe 8-2, an upper supply nozzle 8-3 and an upper supply It includes a support frame 8-4. According to its structural principle, the shape design of the structure follows the principle of the side supply structure. Since the upper part is the main supply route of the supply structure, the volume of the upper supply trough 8-1 is larger than that of the side supply trough 7-1, and preferably the volume of the upper supply trough 8-1 is 0.6 m³. 3 The cross-sectional width of the upper supply pipe 8-2 is the same as that of the side supply pipe 7-2, preferably 25 mm. The cross-sectional length of the upper supply pipe 8-2 is slightly greater than that of the side supply pipe 7-2, preferably 65 mm to 85 mm. The inclination angle of the upper supply pipe 8-2 is smaller than that of the side supply pipe 7-2 to avoid dust problems due to the high drop at the top, preferably 75°. The upper supply pipe 8-2 can adopt a straight section or a multi-angled connecting pipe design, preferably with a connection angle of 75°.

[0066] The high-efficiency supply method for the flange base of the clarifying section of a platinum channel under thermal conditions according to the present invention, and the supply method adapted to the high-efficiency supply device for the flange base of the clarifying section of a platinum channel under thermal conditions, achieve the following: the high-efficiency supply device for the flange base of the clarifying section of a platinum channel is installed in advance, and during the heating process at 1300°C, the cavity region is temporarily sealed with high-temperature cotton, and at this time, while assuming that it does not affect the expansion of platinum, a certain heat retention effect is ensured, with the aim of keeping the internal temperature difference of the platinum space below 100°C. After the channel reaches 1300°C and it is confirmed that the expansion of platinum is almost complete, the supply is started according to the following priority procedure.

[0067] (1) After pre-adjusting and assembling the three supply structures and removing the insulating cotton in the space at the base of the flange, the three supply devices are quickly inserted into the base of the flange, and the distance between the supply nozzle of the supply structure and the platinum body 1 is controlled to be within a predetermined range. Preferably, this range is 30 mm to 40 mm, which ensures that the material powder flows out normally from the end of the supply nozzle of the supply structure and that sufficient material is supplied to the flange base body of the clarification section.

[0068] (2) The operator locks the connecting bolts between the support frame and the three supply structures to ensure the stability of the supply structures.

[0069] (3) One operator stands above the channel body and the other carries the material powder, and once the skills are acquired, the two operators can each be assigned to the top-loading work. An advantage of the present invention is that the supply operator does not need to supply the material in small increments in stages, but instead the entire pot of material can be poured directly, and the material powder automatically enters the flange base.

[0070] (4) Another operator can observe the connection status of the material powder through the lower side opening 5 and use a stainless steel stirring rod to push the material powder in and prevent clogging of the lower supply nozzle outlet.

[0071] This entire process requires two people for loading the material, two for transporting the material, and one for stirring at the bottom. The supply of one flange base can be completed in under 10 minutes, which is a 70% improvement in speed compared to the conventional method of repeatedly supplying the material powder from a tray held by hand using an iron shovel.

[0072] In actual applications, using the high-efficiency thermal supply method for the flange base of the clarification section of a platinum channel according to the present invention reduces the exposure time of the flange base by 70%. This means that the time during which the platinum at the flange base is subjected to external static impact is reduced by 70%. Furthermore, in post-supply process feedback after the actual supply is completed, the temperature difference before and after supply was reduced by 70°C, an improvement of 20°C from the conventional 50°C. This fully demonstrates that the supply method according to the patent of the present invention exhibits a remarkable effect in sealing and heat retention of the flange base of the clarification pipe.

[0073] 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]
