Abstract
A pressing apparatus in a manner of a cage-type screw press, wherein the strainer cage is split up into a plurality of strainer-cage segments. The strainer-cage segments can be sealed along their adjacent sides with the aid of sealing devices so that liquids and solids are effectively prevented from escaping from the gaps between the strainer-cage segments.
Claims8
A pressing apparatus, comprising:
- a cage frame for accommodating a strainer cage, wherein the strainer cage is split in a longitudinal direction into at least two strainer-cage segments:
- and, in each case, at least one sealing device is arranged in a region of contact surfaces of the strainer-cage segments, wherein the sealing device is configured to outwardly seal, as seen in the radial direction of the strainer cage, a gap which is present between the contact surfaces of two interconnected strainer-cage segments, wherein, in a region of a first of the strainer-cage segments, the sealing device has a first sealing strip that is deformable by forces bracing the contact surfaces of the two interconnected strainer-cage segments so that the gap which is present between the contact surfaces is sealed, wherein the first sealing strip of the sealing device projects from the contact surface of the first strainer-cage segment, wherein a first end of the sealing strip is arranged in a recess of the first strainer-cage segment, and wherein a second end of the first sealing strip has a U-shaped contour.
