Abstract

The invention discloses a liquid-solid-liquid three-phase horizontal screw centrifuge which comprises a drum (1), wherein a screw cylinder (2) is arranged in the drum (1); a small end journal (3) and a big end journal (4), which are connected with the drum (1), are arranged at both ends of the drum (1) respectively; a light liquid layer (5), a solid layer (6) and a heavy liquid layer (7) are arranged in the drum (1) from inside to outside respectively; the inner wall of the end, connected with the big end journal (4), of the drum (1) expands outwards to form a small cone angle; light liquid layer discharge channels and a heavy liquid layer discharge channel are arranged on the big end journal (4) respectively; and a liquid phase demarcation mechanism A and a liquid phase demarcation mechanism B are arranged at the light liquid layer discharge channels and the heavy liquid layer discharge channel respectively. The liquid-solid-liquid three-phase horizontal screw centrifuge has the advantages of smart structural design and reliability in use, the separation effect of a light liquid, a solid phase and a heavy liquid can be improved through adoption of the liquid-solid-liquid three-phase horizontal screw centrifuge, and the working stability of the liquid-solid-liquid three-phase horizontal screw centrifuge is guaranteed.

Description

technical field [0001] The invention relates to a decanter centrifuge, in particular to a liquid-solid-liquid three-phase decanter centrifuge. Background technique [0002] At present, the existing decanter centrifuges are mainly used for solid phase dehydration, liquid phase clarification, and solid-liquid-liquid three-phase separation. When encountering a medium whose solid phase gravity is between the two liquid phases, the separation effect is poor, resulting in the failure of the centrifuge to work normally. [0003] In CN205032289U, a utility model patent named "an improved parallel-flow decanter centrifuge" is disclosed, which includes a machine base, a casing, a drum, a screw conveyor, a feed pipe, left and right bearing seats, differential There are several small holes on the drum flange at the junction of the drum column and the cone, and a collection port is provided at the corresponding position of the casing. The heavy phase liquid layer will flow out from the...
