Disk of disk centrifuge

Abstract

The invention relates to a disk of a disk centrifuge. The disk of the disk centrifuge includes a disk body, a plurality of distance ribbed strips and a plurality of feed openings. The disk of the diskcentrifuge is characterized in that the disk body is an upside-down cone dish with a small upper end and a big lower end; the distance ribbed strips are in a spiral shape, and the distance ribbed strips are distributed at the surface of a cone disk and extend backward in the opposite direction of the disk rotation from the small end to the big end of the disk; and axes of the feed openings are parallel to axis of the cone disk, the number of the axes is the same as that of the ribbed strips, and the axes are located above the distance ribbed strips. The distance ribbed strips and the feed openings are symmetrically distributed in the center. Flowing space is formed by a gap of the disk, materials flow into the flowing space from the feed openings of a first layer of disk at the bottom ofa disk set from bottom to top, the small end of the disk is a light phase outlet, and the big end of the disk is a heavy phase outlet. The disk of the disk centrifuge focus on the spiral structures ofthe distance ribbed strips, has the advantages that the affection of the material separation process through the disk structure is improved, and the hysteresis quality of flowing liquid in the gap ofthe disk is decreased, so that the separation efficiency of the disk centrifuge is effectively improved.

Description

technical field [0001] The invention relates to a separation machine in the technical field of centrifugal separation, in particular to a separation machine structure with high separation precision and simple assembly. Background technique [0002] Disc centrifuge is one of the important equipment to achieve efficient separation of solid-liquid, liquid-liquid and other heterogeneous systems. Disc centrifuges are designed using the principles of supergravity settling and shallow pools. Compared with other separation machines, they can not only obtain solid phases with low moisture content and high-purity liquid phases, but also save labor, reduce labor intensity, improve It has the advantages of continuous operation, automatic remote control, safe and reliable operation, and small footprint. It has been widely used in chemical, petroleum, food, pharmaceutical and other industries. [0003] Chinese patent CN105413889A invented a disc centrifuge with an adjustable centripetal ...

AI Technical Summary

Problems solved by technology

However, in the disc centrifuge disclosed, the fixed-distance ribs of the disc all adopt a linear structure, which is not conducive to improving the hysteresis after the material rotates, resulting in the uneven distribution of the fixed-distance ribs and the material near the feed port. Then affect the separation performance of the disc centrifuge
