Problems solved by technology

It solves the problem that the original air curtain type must continuously release a large amount of gas, and there will still be gas leakage, so not only the effect is limited, but also a large amount of gas is wasted, which is practical and progressive

Abstract

The present invention relates to a pressurized gas sealing device for an atmosphere furnace, which belongs to the mechanical category and mainly includes a gas sealing device and a furnace body connected to the gas sealing device, and a channel is provided in the gas sealing device, and there are multiple The blocking part is formed with a storage chamber by blocking, and the storage chamber is used to pressurize the gas in the storage chamber through a gas pressurizing device, and each of the blocking parts is provided with a delivery port, so that when the furnace body When the gas flows in the direction of the gas sealing device, the gas pressurization device is used to fill the accommodating chamber with gas and pressurize, so that the air pressure in the accommodating chamber is slightly lower than the air pressure in the furnace body and suppressed, so that the gas in the furnace body can be reduced. Flow from the direction of the air seal device to achieve the effect of air seal.

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...
