Description

Technical Field

[0001] The utility model belongs to the technical field of glass production equipment, and specifically relates to a device for tying bricks on the pool wall of a photovoltaic glass kiln. Background Art

[0002] Tying bricks on the wall of photovoltaic glass kiln is a heavy and complex systematic work that requires strong technical skills, experience and safety. The working environment is harsh and the labor intensity is high.

[0003] At present, most kilns are designed with a limited number of brick tying times, which limits the life of the kiln. In the prior art, the operation method of tying bricks to the pool wall of photovoltaic glass kilns will have a huge impact on production, not only reducing production quality, but also may cause major production accidents.

[0004] During the production and use of photovoltaic glass kilns, the pool bricks of the kiln pool wall are directly eroded and corroded by the batch material, glass liquid, and space flame at high temperature, which causes thinning, seriously affecting the life of the kiln and even causing major safety hazards. Therefore, it is necessary to perform hot maintenance on the kiln pool wall and tie the pool wall bricks to extend the service life of the kiln.

[0005] In the existing pool wall brick binding technology, the main hot maintenance methods are:

[0006] 1. Lower the glass liquid level: After the glass liquid level in the furnace is lowered to a certain distance, remove the bricks tied to the outside of the corroded pool wall bricks that need to be replaced, and then re-fix a new pool wall brick. A significant reduction in the glass liquid level during the production process will have a huge impact on production, not only affecting the quality of the glass, but also causing major production safety accidents if the glass liquid flows out due to improper operation;

[0007] 2. Top pool wall bricks: directly tie bricks outside the old pool wall bricks, and use new pool wall bricks to push the eroded old pool wall bricks into the kiln in stages. The tiny refractory particles of the old pool wall bricks may enter the original glass along with the glass liquid, forming tiny refractory particle stones in the glass plate, which directly affects the glass production;

[0008] 3. Use cooling water: remove the gap bricks above the corroded old pool wall bricks, insert the cooling water pipe, inject cooling water into the cooling water pipe, use cooling water to solidify the glass liquid, and then carry out the subsequent brick binding operation. In the process of using cooling water to solidify the glass liquid, a large amount of water vapor will appear, which will not only pose a safety hazard, but also cause a large number of bubbles and microbubbles to form in the glass plate, resulting in low product quality qualification rate, poor stability, and increased unit energy consumption;

[0009] 4. Water bag on the inner side of the pool wall and bricks on the outer side: The glass liquid is solidified by placing water bag on the inner side to prevent the safety hazards of fire penetration and glass liquid leakage when dismantling the old pool wall bricks. The water bag is generally welded with heat-resistant stainless steel. After this technology places the water bag on the inner side of the pool wall, the glass liquid near the inner side of the pool wall will be solidified over a large area, increasing the temperature difference between the middle of the kiln and that part, making it easier for the pile to be biased, affecting the melting condition, increasing the difficulty of pile control, and correspondingly increasing fuel consumption.

[0010] For example, the patent document with the authorization announcement number CN210736532U discloses a glass melting furnace pool wall binding brick protection structure, which relates to the field of glass furnace production technology, and includes a cooling air nozzle and the outer wall of the glass melting furnace pool, and the outer wall of the glass melting furnace pool is provided with a ventilation device for guiding the wind direction of the cooling air nozzle, and the outlet end of the cooling air nozzle is arranged on one side of the ventilation device. The technical solution disclosed in the patent document cannot solve the technical problems described above. Utility Model Content

[0014] The cooling water hook comprises a first water pipe, a second water pipe and a connecting pipe connected to the first water pipe and the second water pipe, and the cooling water flows through the first water pipe, the connecting pipe and the second water pipe in sequence.

[0028] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping technicians in the field to have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model and facilitating its implementation.

[0029] It should be noted that, in the following embodiments, the “first” and “second” mentioned do not represent an absolute distinction in structure and / or function, nor do they represent a sequential order of execution, but are merely for the convenience of description.

[0030] like Figures 1 to 4 As shown, the utility model provides a device for tying bricks on the pool wall of a photovoltaic glass kiln, including a cooling water hook for inserting into the glass liquid in the photovoltaic glass kiln, cooling water is passed into the cooling water hook, and the cooling water hook generates heat exchange with the glass liquid in the photovoltaic glass kiln to solidify the glass liquid.

[0031] Specifically, if Figures 1 to 4As shown, the cooling water hook is L-shaped as a whole. The cooling water hook includes a first water pipe 1, a second water pipe 2, and a connecting pipe 3 connected to the first water pipe 1 and the second water pipe 2, and the cooling water flows through the first water pipe 1, the connecting pipe 3, and the second water pipe 2 in sequence. The connecting pipe 3 is an elliptical structure. The upper end of the first water pipe 1 is connected to the water supply system, the upper end of the first water pipe 1 is provided with a water inlet, the lower end of the first water pipe 1 is connected to the water inlet of the connecting pipe 3, the upper end of the second water pipe 2 is connected to the water supply system, the upper end of the second water pipe 2 is provided with a water outlet, the lower end of the second water pipe 2 is connected to the water outlet of the connecting pipe 3, and the distance between the water inlet and the water outlet of the connecting pipe 3 is small. There is an angle α between the length direction of the first water pipe 1 and the second water pipe 2 and the length direction of the connecting pipe 3, and the angle α is an obtuse angle.

[0032] like Figure 4 As shown, the major axis dimension L2 of the connecting pipe 3 is 240 to 260 mm, and the minor axis dimension L3 is 140 to 160 mm.

[0033] In this embodiment, the length L1 of the first water pipe 1 and the second water pipe 2 is 800 mm, the major axis dimension L2 of the connecting pipe 3 is 250 mm, the minor axis dimension L3 is 150 mm, and the angle α between the length direction of the first water pipe 1 and the second water pipe 2 and the length direction of the connecting pipe 3 is 95°.

[0034] Preferably, the cooling water hook is made of a seamless steel pipe with a wall thickness of 3 mm and an outer diameter of 16 mm. An external thread 4 is provided at the upper end of the first water pipe 1, and the first water pipe 1 is threadedly connected to the water supply system for easy disassembly and assembly. An external thread 4 is provided at the upper end of the second water pipe 2, and the second water pipe 2 is threadedly connected to the water supply system for easy disassembly and assembly. No welding process, made by press bending.

[0035] When in use, insert the cooling water hook into the glass liquid of the photovoltaic glass kiln, connect the water inlet pipe and the water outlet pipe of the water supply system to the first water pipe 1 and the second water pipe 2 of the cooling water hook respectively, and pass cooling water into the cooling water hook. The cooling water temperature is lower than the temperature of the glass liquid. Remove the gap bricks on the corroded old pool wall bricks, and insert the connecting pipe 3 of the cooling water hook into the glass liquid close to the old pool wall bricks in the kiln to solidify the glass liquid there. By gently pulling the cooling water hook back and forth, the solidification state of the glass liquid is judged. When the cooling water hook and the glass liquid are firmly solidified together and cannot be pulled, remove the fixing mechanism of the "original binding brick" to fix the old pool wall brick, remove the old pool wall brick, install new pool wall bricks, and use the fixing mechanism to fix the new pool wall bricks. After fixing the new pool wall bricks, stop supplying cooling water to the cooling water hook. After the solidified glass liquid naturally heats up and becomes liquid again, slowly pull out the cooling water hook, and finally reinstall the gap bricks to complete the hot repair pool wall binding operation.

[0036] The above-mentioned device for tying bricks on the wall of photovoltaic glass furnace has the following advantages:

[0037] 1. No need to drop glass liquid, simple operation, safe operation, and little impact on production.

[0038] 2. Do not push old pool wall bricks into the kiln to reduce the occurrence of stones in the glass plate caused by refractory particles and increase glass production.

[0039] 3. It avoids the use of cooling water to solidify the glass liquid, which will produce a large amount of water vapor, which will cause safety hazards and form a large number of bubbles and microbubbles in the glass plate, resulting in low product quality qualification rate, poor stability and increased unit energy consumption.

[0040] 4. The size of the special connecting pipe 3 of the cooling water hook is designed (it can be designed and produced according to the actual size of various pool wall bricks) which is very close to the size of the pool wall bricks. It can solidify the glass liquid near the inner side of the old pool wall bricks that need to be replaced, while minimizing the impact. It will not solidify the glass liquid near the inner side of the pool wall in a large area, reducing the temperature difference between the middle of the kiln and this place, making it difficult for the material pile to be biased, and will not cause great fluctuations in the melting condition, reducing the difficulty of controlling the material pile, and correspondingly reducing the fuel consumption in the process of hot repair pool wall brick tying operations.

[0041] 5. Based on the number of brick tying times designed for the kiln, 1-2 more brick tying times can be added to extend the operating life of the kiln.

[0042] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
