Description

Technical Field

[0001] The utility model belongs to the field of solar cell production, and in particular relates to a furnace door cooling device with a furnace door paddle seat. Background Art

[0002] The solar cell production workshop has a complex variety of equipment, including an important high-temperature production equipment that requires a metal furnace door embedded with a high-temperature resistant sealing ring to achieve a sealing effect during the process.

[0003] At the terminal position, the module with the furnace door paddle seat translates to push the product into the high-temperature cavity for processing. The fitting surface of the metal furnace door is in contact with the fitting surface of the metal flange, and is squeezed through the semi-embedded sealing ring of the metal furnace door to achieve the effect of sealing the high-temperature cavity. The temperature during the process can reach about 900°C, and the process time can reach about 2 hours. When the metal furnace door and the metal flange are in contact, the metal furnace door sealing ring can be cooled by the metal flange cooling water pipe to increase its service life. Before the process is carried out, when the furnace door paddle seat translates to push the product into the high-temperature cavity, the high temperature in front of the high-temperature cavity will greatly affect the service life of the metal furnace door sealing ring. At the end of the process, when the furnace door paddle seat translates to push the product out of the high-temperature cavity, the high temperature in front of the high-temperature cavity will greatly affect the service life of the metal furnace door sealing ring. Due to this repetitive production, the metal furnace door sealing ring will be affected by the high temperature in front of the high-temperature cavity when it is not in contact with the metal flange. The service life of the metal furnace door sealing ring will be greatly reduced, resulting in increased maintenance costs, reduced equipment utilization, and reduced equipment production capacity.
