einrichtung zum mechanischen trennen von flussigkeitsfeststoffgemischen

摘要

A worm press for mechanically separating liquid/solid mixtures comprising a feed region and a pin-barrel pressing region. The worm has at least one flight, each of which flights is interrupted so as to enable the flight to pass the stationary pins in the pin-barrel region. The downstream ends or points of the worm flight portions formed by the interruptions are specially shaped in order to increase considerably the strength and service-life of the highly stressed points. This is achieved by reducing the size of the thrust flank, so that the flank subtends an angle of from 20 DEG to 50 DEG relative to the line perpendicular to the worm axis. Desirably, the thus-angled profiled tip region of the flight portions are interchangeable.
