Title:
逆洗浄可能な濾過装置
Document Type and Number:
Japanese Patent JP2006513073
Kind Code:
A
Abstract:
For each nesting sieve (8, 9), at least one control body (31) can be displaced in the casing (1) relative to the carrier (4), for sectional backwashing of the sieves. Each control body (31) forms a drain channel (36) which is connected for flow via a control opening (37) with a backwashing outlet channel (38) when in the backwashing position. There are two or more independent control bodies, each dedicated to backwashing a section of each sieve. The control body is analogous to a valve plug moved longitudinally, or a rotary slide. The discharge channel extends axially and each control opening penetrates the wall of the discharge channel. Each slide is associated with two or more control openings. The control body is a tube sliding or turning in a bore of the casing. Each backwashing channel is central with respect to its allocated sieve section. Sieve nest(s) have two curved perforated plates enclosing a circular (when flattened) filter inlay. These are mounted in an oval opening (32) of the carrier (4), the convex side facing the approaching flow during filtration. The collection chamber of at least one sieve nest is divided by a partition supporting the perforated plate.
