AI Technical Summary
Existing air filters for liquid oxygen production are prone to clogging or reduced filtration efficiency after prolonged operation, and inspection requires disassembling the outer casing, which is inefficient.
An air filter for liquid oxygen preparation was designed, which adopts a conical tube and filter tube structure. It achieves rapid sampling through a closed plate and an opening component, and improves the sealing performance by combining an inclined closing ring to avoid dust affecting the sampling results.
It enables rapid collection of filtered air, improving collection efficiency, and its airtight design prevents dust from affecting the sampling results during idle periods.
