Embodiment Construction

[0021] The present invention provides a hydrocyclone with a variable cross-sectional area of ​​the pipeline at the inlet section. The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Such as figure 2 and image 3 As shown, the overflow pipe 1 is arranged at the center of the column section 3 , the lower end of the column section 3 is connected with the cone section 4 , and the outlet 5 is provided at the bottom of the cone section 4 . The inlet section 2 of the hydrocyclone is tangent to the column section 3, and the upper surface of the inlet section 2 is flush with the upper surface of the column section 3; along the moving direction of the medium, the first half section 6 of the inner surface of the cyclone inlet section faces outward The direction of the surface 8 is inclined, so that the cross-sectional area of ​​the first half of the inlet section is tapered, and the inclinatio...

Abstract

The invention belongs to the technical field of a hydrocyclone, and particularly relates to a hydrocyclone with the variable pipeline section area at an inlet section. The inlet section of the hydrocyclone is tangent with a column section, and the upper surface of the inlet section is flush with the upper surface of the column section; in the movement direction of medium, a front half section of an inner side surface of the inlet section of the hydrocyclone inclines toward the direction of an outer side surface, so as to allow the sectional area of a pipeline in the front half part of the inlet section to taper; and the oblique direction of the rear half section of the inner side surface of the inlet section of the hydrocyclone is opposite to the front half section of the inner side surface of the inlet section of the hydrocyclone. The hydrocyclone can allow the speed of working medium to increase in the front half part of the inlet section of the hydrocyclone; prefractionation of the coarse particles and fine particles is realized by inertia; separation efficiency of the hydrocyclone is improved; the required equipment of the hydrocyclone is simple; the investment is few; the cost is low; and volume production is easy to realize.

Description

technical field [0001] The invention belongs to the technical field of hydrocyclones, and in particular relates to a hydrocyclone with variable cross-sectional area of ​​a pipeline at an inlet section. Background technique [0002] A hydrocyclone is a device that uses fluid pressure to generate rotational motion, which can separate two-phase or multi-phase media with different particle sizes or density differences. Although the structure of the hydrocyclone is simple, the internal fluid flow is a multiphase flow with three-dimensional strong rotation and high turbulence, and the flow law is very complicated. [0003] The basic working principle of hydrocyclone is as follows: figure 1 As shown, the working medium enters the cyclone along the tangential direction at a certain speed, and the hydrostatic pressure is converted into the rotational motion of the fluid. The solid particles carried in the fluid are redistributed under the action of centrifugal force, among which th...
