AI Technical Summary
The short repair cycle of the fiber solvent filter on the Lyocell production line leads to high production costs.
Design an external flow guide disc, including an inner flow baffle ring, an outer flow guide ring and a first annular flow guide grate. By setting an annular groove on the outer side of the inner flow baffle ring and welding the first annular flow guide grate, the external force is distributed and the welding position is avoided. An alternating stacked flow guide disc structure is adopted.
It extends the repair cycle of the external flow guide disc, reduces production costs, reduces the risk of filter screen puncture, and improves the service life of the equipment.
