Multi-stage solid-liquid separating equipment

Abstract

The invention discloses multi-stage solid-liquid separating equipment. The multi-stage solid-liquid separating equipment comprises a housing, and a multi-stage screen filter mechanism and a plurality of screw extruding solid-liquid separating mechanisms which are arranged in the housing; the housing is provided with a feed inlet and a waste water tank at the bottom, and the waste water tank is provided with a water outlet; the feeding end of the first-stage screen of the multi-stage screen filter mechanism is arranged at the feed inlet of the housing, and the screw extruding solid-liquid separating mechanism is arranged at the discharge end of each stage of the screen; and the solid material discharge ends of all screw extruding solid-liquid separating mechanisms are arranged out of the housing. The multi-stage solid-liquid separating equipment disclosed by the invention filters a solid-liquid mixture in a combined manner by adopting the multi-stage screen filter mechanism and the plurality of screw extruding solid-liquid separating mechanisms, so that a better and more refined solid-liquid separating effect can be provided.

Description

technical field [0001] The invention relates to the technical field of solid-liquid separation, in particular to a solid-liquid separation device. Background technique [0002] The existing solid-liquid separator has only one layer of screen filter structure, and the separation capacity depends on the gap between the screen bars. Since the gap between the screen bars cannot be adjusted and the screen cannot be replaced, it cannot be adjusted according to the actual needs of the site. If finer filtration is required, further construction and additional filter screens will be required after the equipment. The cost is high, and the dry humidity of the filter residue cannot be adjusted well, and the cleaning of the screen screen after filtration also requires labor. Contents of the invention [0003] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a multi-stage solid-liquid separation device, which uses a multi-stage screen f...

Problems solved by technology

[0002] The existing solid-liquid separator has only one layer of screen filter structure, and the separation capacity depends on the gap between the screen bars. Since the gap between the screen bars cannot be adjusted and the screen cannot be replaced, it cannot be adjusted according to the actual needs of the site.

If finer filtration is required, it is necessary to build another project and add a filter screen after the equipment, and the cost is high, and the dry humidity of the filter residue cannot be adjusted well, and the cleaning of the screen screen after filtration also requires labor.
