Problems solved by technology

[0004] By constituting the solid-liquid separation device as described above, it is possible to reliably improve the dehydration efficiency of the object to be processed, that is, the efficiency of extruding the liquid from the object to be processed. As the lead angle becomes smaller, the wear of the movable plate driven by the rotation of the screw becomes significant, and the life of the movable plate is shortened

Embodiment Construction

[0066] Hereinafter, embodiments of the present invention will be described with reference to the drawings, and the aforementioned conventional disadvantages will be more specifically described with reference to the drawings.

[0067] Fig. 1 is a sectional front view showing an example of a solid-liquid separator. This solid-liquid separator can also separate solid components and liquid components from various treatment objects containing oil and other liquids other than water. Here, the case of dehydrating sludge containing a large amount of water will be described.

[0068] The solid-liquid separation device shown in FIG. 1 has an inlet member 1, an outlet member 2, and a solid-liquid separator 3 disposed therebetween. The inlet member 1 is formed in the shape of a rectangular box with an upper opening, and constitutes an inflow port 4 through which sludge flows through the upper opening. Reference numeral 7 denotes the bottom wall of the inlet part 1 . In addition, an open...

Abstract

The present invention relates to a solid-liquid separation device having a solid-liquid separation section provided with adjacent stationary plates and movable plates arranged between the adjacent stationary plates and also having at least one screw extending so as to penetrate the solid-liquid separation section. The movable plates are formed such that they are pushed and moved by the screw that rotates.An object to be processed having entered in the solid-liquid separation section is moved toward the exit of the solid-liquid separation section, and at the same time, filtrate separated from the object is discharged to the outside through a filtrate discharge gap of the solid-liquid separation section. Wear of the movable plates are suppressed with dewatering efficiency for slurry maintained at a high level. The diameter (d) of the shaft (41) of a screw section (21A) on the exit side of the solid-liquid separation section (3) gradually increases from a predetermined position (S1) of the screw in the solid-liquid separation section (3) toward the exit side, and the lead angle of the screw section (21A) is set to the range from 10 DEG to 30 DEG.

Description

technical field [0001] The present invention relates to a solid-liquid separation device, comprising a solid-liquid separation unit having a plurality of adjacent fixed plates and a plurality of movable plates arranged between the adjacent fixed plates, and a solid-liquid separation unit penetrating through the solid-liquid separation unit. Extending at least one screw, the movable plate is formed so that the rotating screw pushes the movable plate, and the object to be treated entering the solid-liquid separation part moves toward the outlet of the solid-liquid separation part by the rotating screw , while the filtrate separated from the object to be treated is discharged to the outside of the solid-liquid separation part through the solid-liquid discharge slit of the solid-liquid separation part, and the object to be treated with reduced liquid content is discharged from the above-mentioned outlet to the outside of the solid-liquid separation part.
