Embodiment Construction

[0014] In this embodiment, the hydrocyclone overflow pipe 5 and the cylindrical section 2, the cylindrical section 2 and the conical section 3, and the conical section 3 and the underflow pipe 4 are all connected by flanges. A solid cylinder 7 is fixed inside the underflow pipe 4, and a sleeve 6 is fixed at the lower end of the overflow pipe 5 through four sheets. The liquid-solid slurry to be separated is driven horizontally and tangentially into the cylindrical section 2 of the hydrocyclone by the slurry pump through the feed pipe 1. Through the action of centrifugal force, the solid particles are thrown to the side wall as the heavy phase and flow along the side wall. Make a spiral movement downwards, discharge through the annular gap between the solid cylinder 7 and the bottom flow pipe 4, and the cleaning product flows out from the overflow pipe 5 as the light phase.

[0015] The following is a comparison of the experimental process and results of a conventional hydrocycl...

Abstract

The invention discloses a hydrocyclone with a novel outlet structure. The hydrocyclone comprises a feed pipe, a cylindrical section, a conical section, an underflow pipe, an overflow pipe, a sleeve and a solid cylinder body, wherein the sleeve is fixed at the inner part of the lower end of the overflow pipe through a thin sheet, the hydrocyclone adopts the design of a short cone and a large-diameter underflow port, and a solid cylinder is inserted into the center of the underflow pipe, so that the area of the annular space underflow port and the area of the underflow port of the common hydrocyclone having the same cone angle are the same. Compared with the common hydrocyclone, the length of the conical section is reduced, the occupied space of the hydrocyclone is saved, and in addition, due to the design of the thin sheet sleeve at the lower end of the overflow pipe of the hydrocyclone and the large-diameter underflow port, the pressure drop is greatly reduced without reducing the separating efficiency.

Description

technical field [0001] The invention relates to the technical field of liquid-solid separation, in particular to a hydrocyclone with a novel outlet structure. Background technique [0002] The working principle of the hydrocyclone is exactly the same as that of the centrifuge, and the heterogeneous mixture with a certain density difference is effectively separated under the action of centrifugal acceleration. Due to the advantages of large processing capacity, high separation efficiency, continuous separation process, simple and compact structure, convenient operation, and easy installation, hydrocyclones are widely used in many fields such as petroleum, chemical industry, metallurgy, mining, food, agriculture, and environmental protection. . [0003] In terms of liquid-solid separation, with the rapid development of high technology, as a conventional separation equipment, the separation performance of traditional hydrocyclones is constantly improving, and its application p...
