AI Technical Summary
The high frequency of filter replacement leads to high energy and economic costs for staff, and the filters cannot maintain a high-precision filtration effect for a long time.
A filtration mechanism was designed, including a through-flow tube, a filter screen, a limit bearing, a transmission rod, a vortex component, and a cleaning component. The rotation of the vortex component drives the cleaning component to automatically clean the filter screen, maintaining the high-precision filtration effect of the filter screen.
It enables automatic cleaning of the filter screen, reduces manual intervention, extends the lifespan of the filter screen, and lowers the replacement frequency and economic cost.
