AI Technical Summary
Existing chimney devices are prone to damage and have poor sealing, resulting in unstable exhaust emissions, which affects product quality. Furthermore, it is difficult to clean the clogging sheet metal parts and tar-like impurities, which affect the negative pressure.
A chimney device was designed, comprising a union, a lower section of the chimney pipe, a negative pressure detection digital pressure gauge, an auxiliary exhaust inlet pipe, an air pump, and a fixed threaded ring. By regulating airflow through negative pressure detection and auxiliary exhaust gas nozzles, and in conjunction with a contraction section, a diffusion section, and a filter screen, stable emission of exhaust gas is achieved.
It achieves stable exhaust gas emissions, reduces airflow disturbance, prevents impurities from entering, ensures sealing and ease of equipment maintenance, and guarantees the continuity and stability of exhaust gas emissions.
