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 clarification 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 at different stages, such as design, manufacturing, stone installation, and pipe management of temperature expansion, and the final operation requirements of the equipment. The clarification 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 a 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 clarification 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, during the actual heating process, relative expansion movement occurs between the platinum and the refractory material, and since the size of the flange itself is larger than that of the refractory brick, it is necessary to secure a space in advance in the flange area of the clarification section. After the heating expansion is completed, supply is carried out quickly at high temperature to ensure the final sealing effect of the flange base.

[0004] Judging from years of analysis of the line body, the main problem restricting the lifespan of the platinum channel is the flange base region of the clarification section. Although this region is ultimately supplied even under thermal conditions, there is still a difference compared to the supply at room temperature in the clearing main section due to the harsh operating environment, narrow space, and strict technical requirements for operators in high-temperature conditions. As a result of comprehensive analysis, the density of the thermal-state supply at the flange base only reaches about 70% of the platinum supply capacity of the main section. Therefore, in actual production, when the operating time of the channel exceeds two years, partial cracks first occur in the flange base region. This is due to oxidation at high temperatures, excessive volatilization of the matrix material, and ultimately a significant reduction in the wall thickness of the tube body. With further deterioration, the platinum tube body finally fractures in that region. This fracture not only depends on the reduction of the wall thickness but is also accelerated by the local Joule heat caused by the operating current.

Summary of the Invention

Problems to be Solved by the Invention

[0005] From the above, it is necessary to consider a more convenient auxiliary method for the sealed supply of the flange base of the clarification section (clearing section). The conventional supply method mainly involves multiple people supplying from different angles simultaneously using simple shovels, etc. This is very inefficient, with a low supply effect and poor supply quality. Furthermore, it is necessary to remove the temporary heat insulation material in this region during the supply process, which exposes the platinum. The longer the time, the greater the temperature difference, which also has an adverse effect on the subsequent heating test run. Therefore, improving the supply efficiency has become the main goal in this region.

[0006] Therefore, it is necessary to solve the problem of the long working time in the conventional sealed supply of the flange base of the clarification section of the platinum channel.

[0007] That is, there is a problem of the long working time in the conventional sealed supply of the flange base of the clarification section of the platinum channel.

[0014] Furthermore, 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 support frame (8-4).

A high-efficiency supply method for the platinum channel fining section flange base in a thermal state is disclosed.

Advantages of the Invention

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

[0020] The supply structure of the present invention penetrates through a supply observation port. The output end of the supply structure is installed in the cavity region, and the input end of the supply structure is installed outside the refractory brick channel. By converting internal supply into simple external supply and realizing rapid supply, it provides an effective time advantage for heat preservation in the flange base region of the fining section of the platinum channel, effectively improves the density of the thermal state supply of the flange base, shortens the working time, and saves time and economic costs. Thus, it has high use value.

[0021] The supply structure of the present invention can quickly construct a supply trough for supply by designing a supply pipe made of special-shaped stainless steel and a supply support frame with a simple fixing structure. The supply nozzle directly extends into the supply gap, enabling a rapid supply function.

[0022] The present invention adopts a method of performing synchronous supply in a common supply trough using a single or three supply structures, effectively improving the supply efficiency and avoiding local supply dead corners.

[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, since the space is narrow, 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, and the dust problem caused by the high drop in the upper part can be avoided.

[0030] The supply structure of the present invention is made of stainless steel material, and since the carbon content is less than 0.08%, the metal tool does not cause contamination to the internal platinum body, and the carbonization reaction at high temperature can be avoided.

[0031] In the heating process of the present invention, the cavity area is temporarily sealed with high-temperature cotton (high-temperature insulation cotton) to ensure a certain heat preservation effect on the premise of not affecting the expansion of platinum, and the temperature difference in the cavity area inside the platinum is made less than 100 °C. In the present invention, the entire pot of the supply material can be injected into the supply structure at one time, and since the supply material automatically enters the flange base, the supply method of adding step by step in small amounts in the prior art can be optimized. In actual operation, by using the present invention, the supply of the flange base can be completed within 10 minutes, and the speed can be improved by about 70% compared with the conventional method of manually holding the material ladle and pouring the material multiple times using a scoop.

[0036] (Embodiment 1) The high-efficiency supply device in the hot state at the flange base of the clarification part of the platinum channel according to the present invention includes a supply structure. A refractory brick channel 4 is installed outside the clarification part of the platinum channel. The clarification part 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 for the normal expansion of the flange 2 during the heating process. A supply observation port is installed in the refractory brick channel 4 corresponding to the cavity region, and the transfer end of the flange 2 penetrates the supply observation port. The supply structure also penetrates 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 arranged outside the refractory brick channel 4, and a reserved 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 through the supply observation port. The output end of the supply structure is set in the cavity area, and the input end of the supply structure is set outside the refractory brick channel, realizing rapid supply by converting internal supply to external simple supply, and providing an effective time advantage for heat preservation in the flange base area of the clarification part of the platinum channel. Thereby, the density of heat state supply at the flange base is improved, the working time is shortened, time and economic costs are saved, and high use value is brought about.

[0038] The above supply structure includes a side supply structure 7. Two side supply structures 7 are provided, and the two side supply structures 7 are symmetrically arranged 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 adopts a hopper structure with a large upper part and a small lower part, and the inclination angle of the hopper structure is set from 75° to 80°. Connection 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 part and an upper short leg part on the side. The upper short leg part is arranged at the outer proximal end of the refractory brick channel 4, and the upper long leg part is arranged at the outer distal end of the refractory brick channel 4. The upper part of the side supply support frame 7-4 is connected to the connection ear by 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 the side supply nozzle 7-3 are designed as inclined multi-angle connection pipes or inclined multi-curvature connection arc multi-stage connection pipes. Also, the cross-sections of the side supply pipe 7-2 and the side supply nozzle 7-3 are rounded rectangles or ellipses, and the above cross-sections are arranged perpendicular to the flow direction of the supplied material. The outlet end of the above side supply nozzle 7-3 is designed to be oblique or rectangular.

[0041] The supply structure of the present invention is designed with a supply pipe made of stainless steel with a special shape and a supply support frame with a simple fixing structure, so that a supply trough for supply can be quickly constructed. The supply nozzle can directly extend into the supply gap and has a rapid supply function.

[0042] The present invention adopts a method of synchronously supplying by installing one or three supply structures on a common trough, which can effectively improve the supply efficiency and avoid local supply dead angles.

[0043] The supply trough adopts a hopper structure with a large upper part and a small lower part. The inclination angle of the side supply trough is set from 75° to 80°. This enables the material powder to slide into the supply pipe, preventing deposition while maintaining normal flow. Also, since the inclination angle is less than 80°, the problem of dust of the raw material powder can be suppressed.

[0044] The side supply pipe according to the present invention adopts an overall diagonal design, so 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 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 as a rounded rectangle or an ellipse, ensuring the dimensional consistency of the supply pipe and the supply nozzle. When the relatively narrow width direction is vertically distributed (vertically distributed) and inserted into the supply gap of the flange base, since the space is narrow, it is necessary to place the side supply pipe 7-2 vertically, that is, the narrow side of the cross-sectional rounded rectangle matches the narrow side of the supply gap, ensuring that the supply pipe smoothly enters the cavity inside the narrow 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 penetrates the side opening 5, the upper supply device 8 penetrates the upper opening 6, and the transfer end of the flange 2 penetrates 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 support frame 8-4. The upper supply trough 8-1 adopts a hopper structure with a large upper part and a small lower part. Connection 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 part and an upper short leg part. The upper short leg part is installed at the outer proximal end of the refractory brick channel 4, and the upper long leg part is installed at the outer distal end. The upper part of the upper supply support frame 8-4 is connected to the connection ear with bolts, and an upper support leg is welded to the bottom of the upper supply support frame 8-4.

[0048] The upper support leg is circular, and the upper supply pipe 8-2 and the upper supply nozzle 8-3 are designed as straight parts or split multi-angle connecting pipes. The cross-sections of the upper supply pipe 8-2 and the upper supply nozzle 8-3 are rounded rectangles or ellipses, and the outlet end of the upper supply nozzle 8-3 is designed in an oblique shape or a rectangle.

[0049] 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 dimensions of the supply pipe and the supply nozzle. The narrow width direction is used for vertical distribution, and the supply pipe can smoothly enter the cavity of the narrow flange base.

[0050] The end of the supply nozzle is designed in an oblique shape or a rectangle, facilitating the further entry of a small amount of material powder inside.

[0051] The upper part of the support frame of the present invention is connected to the connection ear welded to the supply trough and the supply pipe with bolts, and can rotate at a certain angle around the connection point, that is, the span angle of the support frame can be adjusted, so it has a certain rotation and adjustment function.

[0052] In the present invention, a circular support leg is welded to the bottom of the support frame, ensuring a certain anti-slip function.

[0053] The cross-sectional width of the upper supply pipe 8-2 is equal to that of the side supply pipe 7-2, the cross-sectional length of the upper supply pipe 8-2 is greater than that of the side supply pipe 7-2, and the inclination angle of the upper supply pipe 8-2 is greater than that of the side supply pipe 7-2. Also, the volume of the upper supply trough 8-1 is larger than that 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 that of the side supply pipe, thereby avoiding the dust problem caused by the large height difference at the upper part.

[0054] A supply layer 3 is provided between the aluminum body 1 and the refractory brick channel 4. The supply structure is made of stainless steel, and the carbon content of the stainless steel is less than 0.08%. This can prevent the metal tool from contaminating the internal aluminum body and prevent the carbonization reaction at high temperatures.

[0055] In the high-efficiency supply method in the thermal state of the platinum channel clarification part flange base according to the present invention, the following steps are included by using the high-efficiency supply device in the thermal state of the platinum channel clarification part flange base. First (step 1), the cavity area between the flange 2 and the refractory brick channel 4 is temporarily sealed with high-temperature cotton during the heating process. After confirming that the expansion of the platinum channel clarification part has reached a predetermined value, the heat-insulating cotton (thermal insulation cotton) in the cavity area is removed, and the supply structure is quickly inserted into the platinum channel clarification part flange base through the supply observation port, and a reserved distance is provided between the output end of the supply structure and the platinum body 1. In step 2, the supply material is put into the input end of the supply structure. The supply material flows into the platinum channel clarification part flange base through the supply structure, and while observing the supply situation of the supply material through the supply observation port, the high-efficiency supply in the thermal state of the platinum channel clarification part flange base is completed.

[0056] In the heating-up process according to the present invention, by temporarily enclosing the cavity region with high-temperature cotton, it is possible to maintain a certain heat preservation effect without affecting the expansion of platinum. As a result, the temperature difference in the cavity region inside the platinum can be suppressed to less than 100°C. Further, in the present invention, since all the supply materials in the container can be put into the supply structure at once, the supply method of the prior art in which the supply materials automatically enter the flange base and the supply agent consideration is gradually added little by little can be optimized.

[0057] (Example 2) As shown in FIG. 1, the clarification section structure is a mature structure conventionally used in platinum channels, and the clarification section flange structure of the prior art is the main structure in the high-temperature region of the platinum channel. This structure mainly performs high-temperature clarification of the initial molten glass liquid from the tank furnace and removal of bubbles, and plays a role in 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 for supplying current, and two flanges 2 form a set of circuits to convert the current into Joule heat of the platinum body 1 itself, thereby achieving the purpose of heating the internal glass liquid.

[0058] As shown in FIGS. 2 and 3, the high-efficiency supply device in the thermal state of the flange base of the platinum channel clarification section according to the present invention is wrapped with a plurality of layers of refractory material structures outside the clarification section, which are collectively called refractory bricks. There is a main supply layer 3 between the platinum body 1 and the refractory brick channel 4. This supply layer 3 performs normal supply at room temperature. To ensure the normal function of the protruding flange 2, a cavity region of a certain length is reserved in this region of the refractory brick channel 4, which functions as a space for the normal expansion of the flange 2. For the cavity region in the flange 2 region, three supply observation ports are provided on the outside, which are divided into a side opening 5 and an upper opening 6.

[0059] As shown in Figure 3, the supply structure includes two parts: the side supply structure 7 and the upper supply structure 8. There are two side supply structures 7, which are symmetrically arranged on both sides of the channel, and only one upper supply structure 8 is required, for a total of three. The supply structure attaches the three members to the two side openings 5 and the upper opening 6 by a fixed support frame, and the actual supply process is also carried out through these three openings to achieve supply to every corner of the internal cavity region.

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

[0061] As shown in Figure 4, the side supply structure 7 includes four parts: the side supply trough 7-1, the side supply pipe 7-2, the side supply nozzle 7-3, and the side supply support frame 7-4. The side supply trough 7-1 adopts a conventional hopper structure with a large upper part and a small lower part, so that the material powder slides into the side supply pipe 7-2. The inclination angle of the side supply trough 7-1 is 75° to 80°. As a result of repeatedly measuring the fluidity test of the base material powder, it has been confirmed that if the inclination angle is 75° to 80°, the normal flow of the material powder can be ensured and no deposition will be caused. If the inclination angle is less than 80°, the problem of the material powder rising can be avoided. Preferably, according to the one-person loading function of the supply operator and the compression density of the material powder, the volume of the side supply trough 7-1 is 0.3m 3 is.

[0062] The side supply pipe 7-2 adopts an overall inclined design, so that the side supply trough 7-1 does not contact the refractory brick channel 4, and it is designed to be able to reliably send the material powder from the outside into the inner cavity of 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 shape (outer contour) dimensions of the channel refractory brick 4. Considering the fluidity of the material, an inclined multi-angle connection pipe or an inclined multi-curvature joint arc multi-stage connection pipe can be adopted for the side supply pipe 7-2. The cross-section of the side supply pipe 7-2 is a rounded rectangular structure. To ensure the consistency of the sizes of the side supply pipe 7-2 and the side supply nozzle 7-3, and with the relatively narrow width direction distributed in the vertical direction, when inserting it into the supply gap at the flange base, due to the narrow space, the side supply pipe 7-2 needs to be placed vertically. That is, by making the narrow side of the rounded rectangular cross-section coincide with the narrow side of the supply gap, the side supply pipe 7-2 can smoothly enter the narrow flange base cavity. Preferably, the cross-section width of the side supply pipe 7-2 is 25 mm, and the cross-section length and area are designed based on the flow rate and fluidity. The cross-section length of the side supply pipe 7-2 is from 50 mm to 70 mm.

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

[0064] The side supply support frame 7-4 includes a side upper long leg part and a side upper short leg part. The side upper long leg part is arranged on the outside, and the side upper short leg part is arranged on the inside. The upper part of the side supply support frame 7-4 is connected to the connection ears and bolts welded to the side supply trough 7-1 and the side supply pipe 7-2, and can rotate at a certain angle around the connection point. That is, the span angle of the support frame can be adjusted, with the functions of rotation and adjustment. A circular side support leg is welded to the bottom of the side supply support frame 7-4 to ensure a certain anti-slip function.

[0065] As shown in Fig. 5, the upper supply structure 8 is similar to the side supply structure 7. 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 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 path of the supply structure, the volume of the upper supply trough 8-1 is larger than that of the side supply trough 7-1. Preferably, the volume of the upper supply trough 8-1 is 0.6 m 3 . The cross-sectional width of the upper supply pipe 8-2 is the same as that of the side supply pipe 7-2.

[0066] The high-efficiency supply method in the thermal state at the flange base of the clarification part of the platinum channel according to the present invention, and the supply method adapted to the high-efficiency supply device in the thermal state at the flange base of the clarification part of the platinum channel achieve the following, that is, a high-efficiency supply device in the thermal state at the flange base of the clarification part of the platinum channel is installed in advance. During the heating process at 1300°C, the cavity area is temporarily sealed with high-temperature cotton. At this time, on the premise of not affecting the expansion of platinum, a certain heat preservation effect is ensured, and the space temperature difference inside platinum is suppressed to less than 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 procedures.

[0067] (1) Pre-assemble and adjust the three supply structures. After removing the heat-insulating cotton in the space of the flange base, quickly insert the three supply devices into the flange base, and control the distance between the supply nozzle of the supply structure and the platinum body 1 within a preset certain range. Preferably, the certain range is from 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 the supply to the flange base body of the clarification part is sufficient.

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

[0069] (3) One operator stands above the channel body, and another operator transports the material powder. After proficiency, two operators can be assigned to the loading work respectively. The advantage of the present invention is that the supply operator does not need to supply the material in small portions step by step. Instead, the whole pot of the material can be directly poured, and the material powder automatically enters the flange base.

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

[0071] This entire process requires 2 people for material loading, 2 people for material transportation, and 1 person for lower stirring, and the supply of one flange base can be completed within 10 minutes. Compared with the method of manually supplying the material powder many times from a basin held by hand using a conventional iron shovel, the speed is improved by 70%.

[0072] In actual applications, when using the high-efficiency supply method in the hot state at the flange base of the platinum channel according to the present invention, the exposure time of the flange base is shortened by 70%. This means that the time during which the platinum at the flange base is subjected to static impacts from the outside is shortened by 70%. Also, after the actual supply is completed, in the process feedback after supply, the temperature difference before and after supply is reduced by 70°C, showing an improvement from the conventional 50°C to 20°C. This fully proves that the supply method according to the patent of the present invention shows remarkable effects in the sealing and heat preservation of the puff flange base of the clarifying pipe.

[0073] Finally, the above embodiments are for explaining the technical solutions of the present invention and do not limit its protection scope. Despite the detailed description of the present invention based on the above embodiments, those skilled in the art should understand that various changes, modifications, or equivalent replacements can be made to the specific implementation methods of the present invention after reading this disclosure. All of these changes, modifications, or equivalent replacements are included within the protection scope of the claims of the present invention.
