Multistage-separation efficient solid-liquid separation device

Abstract

The invention discloses a multistage-separation efficient solid-liquid separation device. The multistage-separation efficient solid-liquid separation device comprises a device body; the device body mainly comprises a preliminary separator, a first settling area, a buffering area, a second settling area, a filtering area, an inlet and an outlet; a liquid slag treatment area is arranged on the right side of the preliminary separator; the first settling area is arranged in the device body and positioned at the bottom of the preliminary separator; the bottom of the buffering area is communicated with the first settling area through a pipeline; the filtering area is arranged at the bottom of the second settling area; a sliding plate is arranged in the second settling area; a lifting device is arranged between the sliding plate and a bottom plate; the second settling area is communicated with the filtering area through a connecting pipe; the connecting part of the connecting pipe and the second settling area is positioned above the sliding plate. The solid-liquid separation device performs extrusion and drying on the liquid slag to greatly reduce the water content of the liquid slag, improve the efficiency of a filter plate and reduce the filtering load of the device; the device prolongs the hydraulic retention time, improves the settling efficiency of solid particles in the water and has a good solid-liquid separation effect.

Description

technical field [0001] The invention relates to a solid-liquid separation device, in particular to a multi-stage separation high-efficiency solid-liquid separation device. Background technique [0002] The solid-liquid separation device is a device that separates the solid in the liquid by means of filtration. It provides greater convenience at work and is welcomed by people. [0003] Due to the simple structure and single function of the existing solid-liquid separation device, the existing solid-liquid separation device only separates the solid from the liquid through simple filtration, and the water content in the separated solid is high, which is not conducive to the subsequent treatment of the solid. and preservation, and the existing solid-liquid separation device has a short residence time of water in the interior, the solids are not completely settled in the water, and the separation efficiency is low, and the existing solid-liquid separation device is used for a lo...
