AI Technical Summary

Technical Problem

The filter structure of existing gas pressure regulating boxes is easily clogged by impurities after long-term operation, affecting the efficiency of internal and external airflow exchange, and cannot isolate the internal environment when airflow exchange is not required, increasing the risk of corrosion and damage to components.

Method used

The design incorporates an intake pipe, an exhaust pipe, filter plates, a dust scraper assembly, and a self-closing exhaust valve. Alternating filtration is achieved by constructing parallel branch channels, and automatic cleaning is performed in conjunction with the dust scraper assembly and auxiliary cleaning assembly. The self-closing exhaust valve isolates the enclosure when there is no airflow exchange.

Benefits of technology

It improves filtration efficiency and ease of cleaning, reduces the risk of dust intrusion into the enclosure, enhances the corrosion protection of components, and ensures continuous airflow exchange and the isolation of the enclosure environment.
