A device for attaching a filter mesh to the drum of a rotary vacuum drum filter has a number of support elements uniformly disposed about the circumference of the drum and extending along the axial length thereof for carrying the filter mesh and forming individual cells beneath the mesh. At least one filter mesh clamping element is provided between adjacent support elements which includes a spacing body attached to the exterior drum wall and a strip disposed thereabove on the filter mesh and a retainer joining the strip and the spacing body. The spacing body has approximately the same height as the support elements so that the filter mesh is not deformed by the attachment.

Device for affixing a filter mesh to the drum of a rotary drum filter

A rotary vacuum filter for the separation of solids-liquid mixtures has a rotatably supported filter drum having a stationary hollow conduit extending through the interior of the drum which is attached to a vacuum pump. The drum is rotated in a tank containing a mixture to be separated, so that the vacuum action draws the mixture through a filter disposed on the surface of the drum into the interior thereof, where an interior pump removes the filtered liquid and discharges same through the hollow conduit. At no time during the filtration process is air mixed with the filtered liquid, so that subsequent processing to remove air from the liquid is not required.
