JPS5932910A - Apparatus for conveying out precipitated solid substance - Google Patents

Abstract

PURPOSE:To sufficiently separate a solid substance and liquid component and to perfectly perform the removal of adhered fine particles, in discharging the precipitated solid substance from a solid-liquid separation tank, by discharging said solid substance to a vertical direction by rotating a movable shaft having a spiral blade with a specific structure. CONSTITUTION:A liquid to be treated is supplied to a gravity type solid-liquid separation tank 11 having a conical bottom part from an inlet 21 and the solid substance therein is precipitated as a solid substance layer 12 while the separated liquid component is discharged out of the tank 11 from an outlet 22. A vertical tube type solid substance discharge cylinder 13 is attached in the solid-liquid separation tank 11 while a rotary shaft 17 equipped with a spiral blade 16 is provided therein and orifices are formed to the spiral blade 16. The precipitated solid substance 12 is conveyed to a vertical direction by the spiral blade 16 with the rotation of the rotary shaft 17 and the adhered liquid component is separated from the solid substance 12 by centrifugal force generated at this time while org. fine particles adhered to the solid substance are released to be fallen onto the next stage blade from the orifices of said spiral blade 16 along with the liquid component and said solid substance again receives centrifugal separating operation to sufficiently separate the liquid component to be discharged from a discharge port 14.

Description

[Detailed description of the invention]

The present invention relates to a device 11' that separates precipitated objects and liquid components in a water treatment device, and discharges only the solids out of the system. In solid-liquid separators, a mechanical method is most often used for transporting solids that have been divided into particles.
In the solid material unloading, a vertical spiral blade is housed in the solid material discharge cylinder ((a vertical spiral blade is housed in a rotatable manner, a return hole is formed in the spiral blade, and a return hole is formed in the side of the solid material discharge cylinder). By circulating the same-shaped particles through the solid-liquid separator 1 and the solid-liquid separation layer through the discharge hole, one part of the wasteful particulate matter is removed.
; 1 to 4 to increase W particle separation efficiency and perform solid-liquid separation. An example of a device for discharging the precipitated solids is shown in FIG. 1. 1 is a gravity-type liquid separation tank. The liquid to be treated flows into 1 and 2.
The solid matter in the liquid is separated into solid and liquid in the solid-liquid separation tank 1, and the liquid is discharged from the outlet. The solid layer is crushed in the lower part of the tank as precipitated solids, and is carried out by a large number of buffs 5 suspended from cables 4. The precipitated solids carried out by the buffet 5 are
