During filtering, the stock solution is fed from the liquid inlet 410 and then enters the flow guide column 600, flows in the flow guide column 600 along the axial lead direction thereof, and in the process, water flows out through the flow guide holes 610 to form cross flow, so that the stock solution can be filtered uniformly through the hollow fiber module, permeates through the hollow fiber membrane from outside to inside along the radial direction under the action of pressure difference to become permeate, flows to the end of the upper end enclosure 300 in the hollow fiber membrane, passes through the liquid outlet 510, and is finally sent out from the liquid outlet port 121;

the trapped substances are collected outside the hollow fiber membrane, and are transported along with the flowing of the stock solution to the end where the upper seal head 300 is located, and uniformly enter the gap 360 between the upper seal head 300 and the shell body 100 through the collecting holes 330, and are sent out from the backflow port 112.

When cleaning is needed, the reverse flushing is carried out, water is sent from the liquid outlet 510 to clean the outer side of the hollow fiber membrane, so that stains are conveyed to the lower end enclosure 400 and are discharged from the liquid inlet 410 after passing through the sewage discharge outlet 430.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
