Abstract

The invention belongs to a device for solid-liquid separation / classification and non-homogeneous separation, specifically a hydraulic cyclone with improved structure of central post and overflow pipe. The device comprises a feed pipe, a cylindrical section, a coniform section, an overflow pipe and a hollow tubular central post with partial-spiral fins and spiral flow deflectors and provided outside the overflow pipe. The central post is a hollow tube provided thereon with a plurality of holes. The spiral flow deflectors are provided on the outer surface of the central post. The spiral fins are provided on the overflow pipe from the bottom of the overflow pipe to a height below the bottom of an inlet pipe. Compared with the prior art, the separation efficiency of the hydraulic cyclone is increased by 5-10% and the energy consumption is reduced by 20%. The hydraulic cyclone has high stability and reliability in separation efficiency and is suitable for solid-liquid separation in ore dressing, dredging, chemical and petroleum industries.

Description

technical field

[0001] The invention belongs to a device for solid-liquid separation, classification and heterogeneous separation, in particular to a hydrocyclone. Background technique

[0002] At present, the hydrocyclone consists of a cylindrical section, a conical section, an overflow port, an underflow port and a feed port. The overflow port is connected with the top cover at the upper end of the cylinder, and the feed port enters the cylinder cavity along the tangential direction of the side at the upper part of the cylinder. The mixed material enters the hydrocyclone along the tangential direction, and the fluid forms a high-speed rotating flow field in the cylindrical cavity. It moves downward in the axial direction, and when it reaches the cone section, it continues to move downward along the wall of the vessel and is discharged from the underflow port, thus forming an external swirling flow, and the components with low density move towards the central axis, and in ...
