Abstract
A plate-type filter that is provided with a sealing element that is disposed in the flow path of liquid that is to be filtered and seals off the in-flow region relative to the filling space of the filter housing. The sealing element is movable into its sealing position under the pressure of in-flowing liquid. The sealing element is therefore in the sealing position only when liquid is flowing in. When the filter elements are rotated for centrifuging off the filter cake, the sealing element is no longer in its sealing position due to the absence of liquid pressure, so that the sealing element is not stressed during the centrifuging process.
Claims10
In a plate-type filter for filtering liquids, with plate-like filter elements disposed one above another in a housing that is provided with a filling space, said filter elements being seated on a central, rotatable hollow shaft through which filtering liquid is carried away, with inlet means having an in-flow region being provided for supplying liquid that is to be filtered to said hollow shaft and hence to said filter elements, the improvement comprising:
- means for sealing said in-flow region relative to said filling space including at least one sealing element movable into sealing position under pressure of in-flowing liquid to be filtered and disposed in a path of flow of liquid to be filtered from said inlet means to said filter elements, said means for sealing moving out of sealing position when liquid to be filtered is not supplied and forming a means for eliminating stress and wear of said sealing element during rotation of said hollow shaft and filter elements.
