Abstract
A screw press for separating liquids from solid-liquid mixtures, especially pulp suspensions, which has a casing 2 provided with liquid passages, especially divided into segments 3, 3', as well as having a screw 4 rotating inside the casing, a shaft 5, preferably hollow, and a suspension feed area 6. It is primarily characterized by the suspension feed area 6 extending lengthwise in an axial direction on the screw casing 2 with the length and position of the feed opening being adjustable.
Claims13
A screw press for separating liquids from solid-liquid mixtures comprising a casing having liquid flow passages therethrough, a screw having upstream and downstream ends rotating inside of said casing for conveying said solid-liquid mixture through said casing in a transport direction and forcing liquid through said liquid flow passages and solid-liquid mixture feed means for feeding said solid-liquid mixture into said casing through a feed opening wherein said casing comprises a plurality of casing segments and wherein at least one of said casing segments contains said feed opening and wherein said casing segments are interchangeable to change the position of said feed opening.
A screw press for separating liquid from a pulp-liquid mixture comprising:
- a. a cylindrical casing having a plurality of liquid passages through the sides thereof thereby forming a screening structure, said casing being divided into a plurality of interchangeable cylindrical segments;
- b. a conveying screw mounted inside said cylindrical casing and including means for rotating said conveying screw to convey said pulp-liquid mixture through said casing and forcing liquid out through said plurality of liquid passages;
- c. a feed area for feeding said pulp-liquid mixture into said casing, said feed area including a slit through the side of at least one of said cylindrical segments;
- and
- d. means for changing the position of said feed area with respect to said cylindrical casing including means for interchanging some of said cylindrical segments.
