一种排气系统用隔热防火罩
By using a motor-driven reflector assembly and an air pressure balancing mechanism, the problem of poor heat insulation and temperature control in the exhaust system fireproof cover under high-temperature conditions is solved. This achieves active reflection of external light and heat and internal airflow circulation heat exchange, providing all-round heat insulation and fire protection.

AI Technical Summary
The existing exhaust system fireproof cover cannot actively adjust the angle of external light and heat radiation blocking. Under open-air sunlight and high temperature environment, external heat can easily penetrate, resulting in aggravated temperature rise around the pipe, poor heat insulation and temperature control effect, and lack of active airflow heat exchange structure.
The reflector assembly is driven by a motor and adjusts the reflector angle through a gear and ring transmission system. Combined with an inert gas heat insulation chamber and a pressure balancing mechanism, it can actively reflect external light and heat and perform internal airflow circulation heat exchange. It is equipped with a magnetic strip cleaning roller and a multi-layer heat insulation protection structure.
It achieves the reflection of external light and heat radiation while reducing internal heat intrusion, preventing the aging of heat insulation components, keeping the reflector clean, providing all-round heat insulation and fire protection, preventing heat accumulation and spark leakage, and improving the overall heat insulation and temperature control effect.
