Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of substrate glass manufacturing, and particularly relates to a hot-state filling device and method for a flange root of a platinum channel refining section. BACKGROUND
[0002] As core equipment in the production and manufacturing process of substrate glass, the platinum channel needs to be combined with the operation scenes at different stages and the final equipment operation requirements to perform periodic safeguard operations, whether from the aspects of design and manufacturing, or from the aspects of masonry installation and management of temperature expansion. For the refining section, it is the component with the highest running temperature in the entire platinum channel structure and is prone to damage. Since the platinum channel is mainly made of platinum rhodium alloy material, although it has excellent high-temperature resistance and corrosion resistance, long-term operation above 1400 DEG C and continuous erosion by internal glass liquid still pose great challenges to the platinum base itself.
[0003] During the initial installation process of the platinum channel, most areas of the refining section can be sealed at room temperature. The sealing method mainly seals and fills the space between the platinum exterior and the refractory bricks by using high-temperature-resistant zirconia powder. However, for the flange area of the platinum channel, since there is still relative expansion displacement between the platinum and the refractory material during the actual temperature rising process, and the size of the flange is larger than that of the refractory bricks, it is necessary to reserve space in advance for the flange area of the refining section. After the temperature expansion is completed, rapid filling at high temperature is performed to ensure the final sealing effect of the flange root.
[0004] From the analysis of the line body in recent years, the main problem that restricts the service life of the platinum channel is the flange root area of the refining section. Although the area is finally filled at high temperature, the harsh operating environment, the small space and the strict technical requirements for the operator at high temperature make the area different from the filling at room temperature of the main section of the refining section. After comprehensive analysis, the compactness of the hot-state filling of the flange root can only reach about 70% of the compactness of the main section platinum filling. Therefore, in actual production, after the running time of the channel exceeds 2 years, local cracking will first occur in the flange root area, which is mainly due to oxidation at high temperature, resulting in the transition volatilization of the base material in the area, and finally the wall thickness of the tube is seriously thinned. With further deterioration, the platinum tube will eventually break down in this area. The breakdown depends not only on the thinning of the wall thickness, but also on the local joule heat caused by the running current, which will further accelerate the breakdown.
[0005] In summary, for the sealing filling of the flange root of the clarifying pipe, a more convenient auxiliary method needs to be considered. The current filling method mainly uses simple tools such as shovels to fill gradually by multiple personnel from different angles, which is extremely low in efficiency and poor in filling effect. Moreover, the filling process requires the temporary removal of the insulation cotton in this area, which will cause the platinum to be exposed, and the longer the time, the greater the temperature difference, which will also adversely affect the subsequent warm-up trial production. Therefore, improving the filling efficiency has become the main goal of this area.
[0006] Therefore, there is a need to solve the problem of long operation time of the existing platinum channel clarifying flange root sealing filling. SUMMARY

[0063] Example two
[0064] As shown in Figure 1 , the structure of the refining section is the mature structure of the platinum channel that is now in use. The flange structure of the refining section in the prior art is the main structure of the high-temperature zone of the platinum channel, which mainly undertakes the high-temperature refining and bubble removal of the glass liquid from the pool furnace, and purifies the glass melt. The refining section structure includes two main components, the platinum body 1 and the flange 2. The flange 2 is mainly used for transmitting current, and the two flanges 2 form a loop to convert the current into the Joule heat of the platinum body 1 itself, so as to achieve the purpose of heating the internal glass liquid.
[0065] As shown in Figure 2 and Figure 3 , a hot filling device for the root of the flange of the refining section of the platinum channel. Outside the refining section, there are several layers of refractory material structure, collectively referred to as refractory bricks. There is a filling layer 3 between the platinum body 1 and the refractory brick channel 4 of the main section. The filling layer 3 is normally filled at room temperature.

[0073] A hot-state filling method for the flange root of the platinum channel clarification section, matched with a hot-state filling device for the flange root of the platinum channel clarification section, realizes the advance installation of the hot-state filling device for the flange root of the platinum channel clarification section, temporarily blocks the cavity area with high-temperature cotton during the process of heating to 1300℃, ensures a certain heat preservation effect without affecting the platinum expansion, so as to make the temperature difference of the cavity in the platinum as small as possible, i.e. less than 100℃, after the channel runs to 1300℃, it is checked and confirmed that the platinum expansion has basically reached the position, and then the filling is started according to the following preferred method:
[0074] (1) three material conveying structures are debugged and assembled in advance, after the heat preservation cotton in the cavity of the flange root is removed, the three material conveying devices are quickly moved and inserted into the flange root, and the distance between the material conveying nozzle of the material conveying structure and the platinum body 1 is controlled in a preset range, preferably, the preset range is 30mm to 40mm, which guarantees the normal outflow of the end material powder of the material conveying nozzle and the filling sufficiency of the clarification section flange root body;
[0075] (2) the operator locks the connecting bolts of the support frame and the three material conveying structures respectively, so as to ensure the stability of the material conveying structure;
[0076] (3) one person is arranged to stand above the channel body, and another person is arranged to transport the material powder, after being skilled, two persons can be arranged to carry out the feeding operation, the advantage of the present application lies in that the feeding personnel do not need to feed gradually in small batches, but can directly pour the whole pot of material, and the material powder will automatically enter the flange root;
[0077] (4) Another person is arranged to observe the powder butt joint condition at the lower side part opening 5, and to use a stainless steel drill to push the material, so as to avoid the blockage of the lower material conveying nozzle outlet.
[0078] The whole process needs 2 persons for feeding, 2 persons for conveying, and 1 person for pushing the material at the lower part, and one flange root can be filled within 10 minutes, which is 70% faster than the traditional method of holding a material basin with an iron shovel.
[0079] Through practical application, the hot-state filling method for the flange root of the clarification section of the platinum channel adopts the method, the exposure time of the flange root is shortened by 70%, which means that the time of the flange root affected by the external ring static impact is shortened by 70%, and after the actual filling is completed, the process feedback of the temperature difference before and after filling is reduced by 70℃, which is 20℃ higher than the traditional 50℃, which fully shows that the filling of the present application has a significant sealing and heat preservation effect on the flange root of the clarification pipe.
