Abstract
Description
technical field
[0001] The present invention relates to machinery, in particular to an atmosphere furnace pressurized air seal device, especially an atmosphere furnace pressurized air seal device which utilizes an air pressure slightly lower than the original air pressure to suppress and seal the original air pressure for leakage. Background technique
[0002] Taking the atmosphere furnace as an example, the general pressurized furnace body generates high-pressure gas in the furnace body. Although necessary measures are taken to prevent the leakage of such high-pressure gas, even if the operation is stopped, the high-pressure gas will continue to flow to the outside world. The impact is the leakage of gas. In order to solve this problem, some manufacturers have improved or added to the lack of gas leakage. One of the ways is to add An air curtain is set up, that is, a plurality of air nozzles are used to spray air at the port of the feed end or the discharge end, so as to pr...
