MODULAR SCREW PRESS Russian patent published in 2018 - IPC B01D29/46 

FIELD: technological processes.

SUBSTANCE: screw press (14) for separating liquid from a solid-liquid mixture comprises filter casing (18) having inlet and outlet sections (24, 26) and filter section (28) therebetween. Screw (20) is mounted in casing (18) for conveying the solid-liquid mixture from inlet section (24) to outlet section (26), while compressing the solid-liquid mixture and forcing at least part of a liquid content thereof to be expelled out of filter casing (18). Casing (18) and screw (20) having a modular structure. Filter section (28) has at least first and second serially interconnectable filter sections (28a, 28b), and screw (20) has at least first and second serially interconnectable screw sections (20a, 20b) respectively disposed in first and second filter sections (28a, 28b) for joint rotation as a unitary component. First and second screw sections (20a, 20b) have continuous screw flight (34) having a flight outside diameter. First and second screw sections (20a, 20b) are detachably coupled to one another by coupling (62) provided at the outside diameter of flight (34).

EFFECT: modular screw press is disclosed.
