AI Technical Summary
Existing filter components are slow in filtering cell clusters, are prone to clogging, and easily form water films, which affects the filtration effect.
It employs an inclined filter screen and air pressure-assisted filtration, with gas delivered through a delivery pipe to accelerate filtration, using gas pressure to clear blockages, and combining this with clean water to purify the air and prevent water film formation.
It improves filtration speed, prevents clogging, ensures smooth filtration process, reduces water film impact, and achieves rapid and efficient cell cluster filtration.
