연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

The invention relates to a filtering device (100) comprising: a filter support element (10) which is movably mounted in the housing (30), which has the shape of a cylindrical bolt, and which has multiple filter chambers (11.1, 11.2; 12.1, 12.2), a filtering element being arranged in each said filter chamber; and an inlet channel (31.1, 31.2 32.1, 32.2) and an outlet channel (41.1, 41.2; 42 0.1, 42.2) in the housing (30), wherein the inlet channel and the outlet channel are each to be connected to at least one filter chamber in a production position. The aim of the invention is to increase the effective filtering surface. This is achieved in that at least two pairs of filter chambers are provided on the filter support element. The filter chambers of each pair are arranged on the filter support element in a diametrically opposed manner, and there are no connections between the filter chambers within the filter support element. At least one respective intermediate channel (13.1, 13.2, 14.1, 14.2) that extends in the direction of the longitudinal axis (19) of the filter support element (10) is provided between the outlet channels in the housing and the filter chambers. Intermediate channels of different lengths are provided for each pair of filter chambers.

1. A filtering device for filtering fluids, said filtering device having a housing and a cylindrical bolt-shaped filter support element: said cylindrical bolt-shaped filter support element mounted movably in said housing and having multiple filter chambers, each of said filter chambers having a filter element,said housing having a plurality of inlet channels and a plurality of outlet channels configured such that each of said filter chambers moves into connection with a respective inlet channel and a respective outlet channel when said filter support element is moved to a production position,such that when said filter support element is in the production position a respective inlet channel in said housing leads to a respective filter chamber and each of said outlet channels in said housing leads away from a respective filter chamber, and wherein,said filter support element has at least two pairs of said filter chambers, each said pair comprising two filter chambers arranged diametrically opposed on said filter support element such that within said filter support element there are no connections between said filter chambers,said filter support element has a plurality of intermediate channels each configured to be positioned between a respective outlet channel in said housing and a respective filter chamber in said filter support element, said filter support element having a longitudinal axis, each of said intermediate channels extending in a longitudinal direction, each said pair comprising two filter chambers having two respective intermediate channels of different longitudinal length, such that:when said filter support element is in said production position, each filter chamber of one of said pairs is connected with at least one of said inlet channels and with at least one of said outlet channels, andsaid filter support element is moveable to a maintenance position in said housing, and when said filter support element is in the maintenance position one or the other filter chamber of one of said pairs is connected reciprocally with at least one of said outlet channels. 2. The filtering device according to claim 1, wherein said intermediate channels are formed at an outside surface of said filter support element. 3. The filtering device according to claim 1, wherein said intermediate channels are formed as slotted hole shaped grooves. 4. The filtering device according to claim 1, wherein said intermediate channels are formed by rows of individual recesses. 5. The filtering device according to claim 1, characterized in that in cross section two of said inlet channels have outlets that open respectively to two of said filter chambers and that are located at opposing sides of said filter support element and that are arranged on a symmetrical axis on a first diameter line, andtwo of said outlet channels lead from each filter chamber to opposing sides of the filter support element and have outlets arranged on a symmetrical axis on a second diameter line, such that the second diameter line extends perpendicular to the first diameter line. 6. The filtering device according to claim 5, wherein said filter chambers and said inlet channels of one of said pairs are mirror-inverted relative to said filter chambers and said inlet channels of the other of said pairs, in relation to a first transverse axis extending laterally through said filter support element. 7. The filtering device according to claim 6, wherein said outlets of said inlet channels leading to said filter chambers of both said pairs are arranged mirror-symmetrically in relation to the first transverse axis. 8. The filtering device according to claim 1, wherein said intermediate channels include two longer intermediate channels and two shorter intermediate channels, said two longer intermediate channels located on different sides of a first transverse axis, said two shorter intermediate channels located on different sides of the first transverse axis, said two longer intermediate channels located on different sides of a longitudinal axis of the filter support element, and said two shorter intermediate channels located on different sides of the longitudinal axis. 9. The filtering device according to claim 8, wherein said intermediate channels are configured such that a line connecting centers of said longer intermediate channels intersects a line connecting centers of said shorter intermediate channels at an intersection point of the first transverse axis and the longitudinal axis. 10. The filtering device according to claim 1, further comprising a second cylindrical bolt-shaped filter support element movably mounted in said housing, each of said filter support elements having two pairs of filter chambers. 11. The filtering device according to claim 1, wherein said housing has at least one back flush channel configured to move into connection with at least one of said filter chambers to arrange said filtering device in a back flush maintenance position. 12. The filtering device according to claim 1, wherein said housing has a pair of inlet channels configured to be connected to each filter chamber, such that each pair of inlet channels have outlets that are longitudinally offset in relation to each other. 13. The filtering device according to claim 12, wherein said two inlet channels of each pair branch out in a V-shape.
