Description

High-temperature sealing mechanism for furnace mouth

Technical Field

The utility model relates to a high temperature seal technical field specifically is a fire door high temperature seal mechanism.

Background

As is known to all, because the temperature in the furnace is far higher than the long-term use temperature of the silicon rubber material, the leakage of a small amount of furnace gas can cause the local high-temperature aging and ablation of the silicon rubber material, once the sudden sealing fails, the high-temperature steam can cause great damage to surrounding facilities and personnel, the treatment process must be forcibly terminated, and the material undergoing the activation treatment in the furnace is at the risk of being scrapped.

Through search, chinese patent with publication number CN210265840U discloses a furnace mouth high-temperature sealing mechanism. When the furnace door is closed to the furnace body, the annular inflatable rubber ring and the spring bow plate can be compressed and deformed, when the annular inflatable rubber ring fails to release pressure, the spring bow plate still can provide a basic sealing effect, the furnace atmosphere is guaranteed not to leak, or the leakage amount is reduced, so that the harm to surrounding personnel and equipment is reduced. However, the furnace door has certain disadvantages that when the furnace door is opened, the internal air pressure is too strong, so that the gas in the furnace is sprayed outwards, and surrounding personnel and equipment are damaged. In view of this, we propose a high-temperature furnace mouth sealing mechanism.
