Abstract

A spindle press comprises a housing with a circular cylindrical upper part and a lower part. A press spindle, which is drivable in a rotating manner via a drive pipe by a drive arrangement, is supported in an upper bearing and a lower bearing of the housing so as to be rotatable. A spindle body of the press spindle carries worm wings on the outside and compressor blades farther above, which all extend in the vicinity of a screen casing of the upper part. The screen casing is enclosed at a distance by a spray casing and provided with holes for pressed out fluid only from the compressor blades down. The spindle body also comprises perforations for the pressed out fluid only from the compressor blades down. Above the compressor blades a helically constructed front wall is welded in between an annular wall and the screen casing which is unperforated at that point. On the lower side of the front wall, wet pulp arrives tangentially through a filling opponent of the upper part.
