Title:
FILTERING DEVICE AND FIBROUS PART REPLACEMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2018/216491
Kind Code:
A1
Abstract:
This filtering device (1) has a cylindrical part (2) having a vertically-extending cylindrical shape and having an upper opening (23) open to the outside. A separating part (3) divides an inner space (20) of the cylindrical part (2) into an upper space and a lower space. The separating part (3) allows liquid to pass therethrough. A fibrous part (4) is a fibrous filtering member accommodated in an upper space (201) which is a space above the separating part (3). The fibrous part (4) is compressed, during filtering, on the separating part (3) and captures suspended substances in raw water flowing into the inner space (20) from the upper opening (23). A discharging part (5) discharges treated water, which has passed through the fibrous part (4) during filtering, from a lower space (202) which is a space below the separating part (3). An exchange part (81) including at least a portion of the fibrous part (4) and at least a portion of the separating part (3) can be attached to/detached from the filtering device (1). Accordingly, the fibrous part (4) can be easily replaced.
