AI Technical Summary
In the existing filtration device, impurities easily adhere to the filter screen and form a clogging layer during the preparation of diisopropyl azodicarbonate, requiring manual disassembly and cleaning, which consumes a lot of time.
Design a filtration device comprising a filter tank, a water supply and drainage component, and an auxiliary cleaning component. It utilizes negative pressure backwashing and a motor-driven cleaning brush to automatically clean impurities on the filter screen, thereby achieving automatic backwashing.
Impurities on the filter cylinder can be automatically cleaned without manual disassembly, improving filtration efficiency and reducing manual maintenance time.
