Abstract

The utility model belongs to the technical field of a hydraulic cyclone and particularly relates to a hydraulic cyclone with a variable entrance section pipeline section area. An entrance section of the hydraulic cyclone is tangent to a column section and the upper surface of the entrance section is leveled with the upper surface of the column section; the front half section of the inner side surface of the entrance section of the cyclone is inclined towards the direction of the outer side surface along a medium movement direction so that the section area of a pipeline of the front half part of the entrance section is gradually reduced; and the inclined direction of the rear half section of the inner side surface of the entrance section of the cyclone is opposite to that of the front half section of the inner side surface of the entrance section of the cyclone. According to the hydraulic cyclone disclosed by the utility model, the speed of working mediums at the front half part of the entrance section of the hydraulic cyclone is increased and primary separation of coarse and fine grains is realized on the entrance section by using inertia, so that the separation efficiency of the hydraulic cyclone is improved; and the hydraulic cyclone has the advantages of simple needed equipment, less investment, low cost and easiness in large-batch production.

Description

A kind of change entrance pipeline section ponding power cyclone
Technical field
The utility model belongs to the hydrocyclone technical field, is specifically related to a kind of change entrance pipeline section ponding power cyclone.
Background technology
Hydrocyclone is a kind of device that utilizes fluid pressure to produce and rotatablely move, and can make the different-grain diameter particle or exist two-phase or multiphase medium of density contrast to separate.Although hydrocyclone is simple in structure, its inner Fluid Flow in A is the Multiphase Flow of three-dimensional strong rotation and high turbulence, and flowing law is very complicated.
The hydrocyclone basic functional principle as shown in Figure 1, working media tangentially enters cyclone with certain speed, this moment hydrostatic pressure be converted into rotatablely moving of fluid.The solid particle that carries in fluid redistributes under the effect of centrifugal force, and the medium that wherein coarse granule or density are large is distributed in the larger outer eddy flow of radius because suffered centrifugal force is large, is finally discharged by underflow opening with the form of underflow; The medium that fine grained or density are little is distributed in the cyclone central area, forms inward eddy, is finally discharged by overflow pipe with the form of overflow.
The hydrocyclone entrance structure mainly comprises two aspects, the one, and the shape of cross section of entrance mainly divides two kinds of rectangle and circle shapes; The 2nd, entrance and the form that the cyclone shell of column passes through mutually divide involute-type, tangent type, arc line type, spiral line type.But adopt the cyclone of above-mentioned entrance structure and to bore the separation that section realizes medium at shell of column.
Summary of the invention
The purpose of this utility model is to provide a kind of change entrance pipeline section ponding power cyclone; this structure can improve medium at the flow velocity of entrance; make large or fine granule or weight medium at entrance, initial gross separation can occur, for good basis is set up in the separation of medium in cyclone shell of column and cone section.
The technical solution adopted in the utility model is:
Entrance and the shell of column of this hydrocyclone are tangent, and the upper surface flush of the upper surface of entrance and shell of column; Along the medium motion direction, the cyclone entrance inner surface first half section direction on surface laterally tilts, entrance first half pipeline section is gradually contracted, and the incline direction of cyclone entrance inner surface second half section is opposite with cyclone entrance inner surface first half section.
Angle between described cyclone entrance inner surface first half section and outer surface is 15 ° to 20 °.
Angle between described cyclone entrance inner surface second half section and cyclone entrance inner surface first half section is 120 ° to 130 °
Described cyclone entrance inner surface first half section and cyclone entrance inner surface second half section Length Ratio are 3 to 3.5.
The advantage that the utlity model has is:
(1) adopt this entrance structure, can impel medium to realize initial gross separation at entrance;
(2) increase fine grained or the little medium of density in the time of staying of shell of column;
(3) improve the separative efficiency of hydrocyclone;
(4) simple in structure, easily realize producing in enormous quantities.
Description of drawings
Fig. 1 is existing hydrocyclone basic functional principle schematic diagram;
The structural representation of the change entrance pipeline section ponding power cyclone that Fig. 2 provides for the utility model;
The top view of the change entrance pipeline section ponding power cyclone shell of column that Fig. 3 provides for the utility model.
Number in the figure:
The 1-overflow pipe; The 2-entrance; The 3-shell of column; 4-bores section; The 5-outlet; 6-cyclone entrance inner surface first half section; The 7-cyclone entrance inner surface second half section; The 8-outer surface.
The specific embodiment
The utility model provides a kind of change entrance pipeline section ponding power cyclone, below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figures 2 and 3, overflow pipe 1 is arranged on the center of shell of column 3, and the lower end of shell of column 3 is connected with cone section 4, and the bottom of cone section 4 arranges outlet 5.The entrance 2 of this hydrocyclone is tangent with shell of column 3, and the upper surface flush of the upper surface of entrance 2 and shell of column 3; Along the medium motion direction, cyclone entrance inner surface first half section 6 direction on surface 8 laterally tilts, entrance first half pipeline section is gradually contracted, and the incline direction of cyclone entrance inner surface second half section 7 is opposite with cyclone entrance inner surface first half section 6.
In the present embodiment, angle between cyclone entrance inner surface first half section 6 and outer surface 8 is 17 °, angle between cyclone entrance inner surface second half section 7 and cyclone entrance inner surface first half section 6 is 125 °, and cyclone entrance inner surface first half section 6 is 3.2 with cyclone entrance inner surface second half sections 7 Length Ratio.
When medium flows in gradually reducing pipeline, flowing velocity increases, when medium passes through the cyclone entrance inner surface first half section 6 of inclination, due to effect of inertia, the medium that coarse granule or density are large can move by the outer surface along cyclone entrance inner surface first half section 6 directions to shell of column 3, forms to be close to the outer eddy flow that shell of column 3 outer surfaces move downward; And the little medium of fine grained or density can in cyclone entrance inner surface first half section 6 and the central area motion of cyclone entrance inner surface second half sections 7 intersection to shell of column 3, reach the purpose of different medium initial gross separation.
