Embodiment 1

[0022] Such as figure 1 Shown: when the present invention is used with the disc set, the material containing the mixture of light and heavy phases enters the disc gap, the heavy phase is thrown to the drum wall under the action of centrifugal force, and the light phase flows toward the axial direction of the disc holder. As the diameter of the neutral hole gradually increases, the phenomenon of uneven distribution of materials in the gap of each layer of discs is improved, the centrifugal separation effect is improved, and the separation performance of the disc centrifuge is improved.

[0023] The invention controls the diameter of the feeding neutral hole of a single disc, so that the neutral hole is gradually expanding, which improves the phenomenon of uneven distribution of the flow field in the gap of each layer of discs, makes the distribution of the flow field more reasonable, and improves the Separation efficiency makes the product after centrifugal separation have high...

Abstract

The invention discloses a diverging type neutral hole disc group of a disc centrifuge. The diverging type neutral hole disc group of the disc centrifuge comprises a disc group and a disc holder (1), wherein the disc group is composed of a plurality of discs (2). The diverging type neutral hole disc group of the disc centrifuge is characterized in that each disc in the disc group is provided with arib (3) and a feeding neutral hole (4) which gradually increases in size from bottom to top to form a diverging shape. The change of the size of the feeding neutral hole of each single disc is controlled, so that the neutral hole as a whole is a smaller-end-down diverging type, the problem of uneven distribution of the feeding of the separation liquid to be separated in each layer is solved, andthe centrifugal separation effect is 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 centrifuges are widely used and are very common in industrial production, such as: chemical, pharmaceutical, food, transportation, light industry and biological industries. Its function is to purify dispersed materials, recover dispersed materials, and protect follow-up equipment, mainly to purify, classify, and classify materials. As the core part of the disc centrifuge drum, the disc directly contacts with the material, participates in the separation process and the process of discharging after separation, which has an important impact on the separation effect and efficiency of the separator. [0003] At present, the neutral hole on the disc set of common disc centrifuges is a vertical channel, and the structural parameter...
