Abstract
For an overflow pipe for hydrocyclone, it is characterized in that: comprise overflow pipe, described overflow pipe main pipeline lower end is provided with spherical crown, and this spherical crown is provided with sieve aperture, and described sieve aperture is provided with sieve aperture dividing plate.The utility model structure is simple, and processing, transformation easily realize.Liquid-solid, Liquid liquid Separation and the gas solid separation of the industries such as oil, chemical industry, environmental protection, medicine, food can be widely used in, be particularly useful for the occasion high to fine particle separation requirement.
Description
Technical field
The utility model relates to a kind of hydrocyclone overflow pipe.
Background technology
Hydrocyclone is the equipment for separating of the large or fine granule in slurries.Sometimes also for slurry dewatering.Partial pressure formula and gravity type two kinds, slurries depended on pressure or gravity are entered by cyclone upper feed inlet, and under centrifugal action, coarse particles material is thrown to wall and rotated and discharges together with the dope formed downwards.Less particulate matter rotates to a certain degree and is discharged by overflow pipe with bumpy flow on secondary.Enter the two-phase fluid of cyclone, due to the frictional resistance effect of its wall, wherein a part is first upwards inside along top cover lower surface again, moves downward again, finally converge with inward eddy and discharged by the overfall of overflow pipe along vortex finder outer wall.This part lid is dirty is exactly usually said short-circuit flow, discharges many heavy phase particles just directly enter overfall and drain through overflow pipe without separation because it directly enters overflow pipe.The in use overflow of current cyclone often has runs thick phenomenon.
Utility model content
The purpose of this utility model is the weak point avoiding above-mentioned phenomenon, provides a kind of interior media good fluidity, separative efficiency is high and anti-race is thick overflow pipe.
The purpose of this utility model is realized by following measure: a kind of overflow pipe for hydrocyclone, it is characterized in that: comprise overflow pipe, lower end, described overflow pipe main channel is provided with spherical crown, and this spherical crown is provided with sieve aperture, and described sieve aperture is provided with sieve aperture dividing plate.
Described spherical crown also can be cone, tabular.
Described sieve aperture presses concentric circles distribution.
Advantage of the present utility model is mainly: the utility model structure is simple, and processing, transformation easily realize.Liquid-solid, Liquid liquid Separation and the gas solid separation of the industries such as oil, chemical industry, environmental protection, medicine, food can be widely used in, be particularly useful for the occasion high to fine particle separation requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, overflow pipe, 2, overflow pipe main channel, 3, spherical crown, 4, sieve aperture.
Detailed description of the invention
Below in conjunction with accompanying drawing, be described further structure of the present utility model and work characteristics, the purpose of this utility model is realized by following measure:
As shown in Figure 1, a kind of overflow pipe for hydrocyclone, comprises overflow pipe, and described overflow pipe main pipeline lower end is provided with spherical crown, and this spherical crown is provided with sieve aperture, and described sieve aperture is provided with sieve aperture dividing plate.Described spherical crown can be cone, tabular, can arrange the shape of spherical crown according to overflow pipe use occasion difference accordingly; Described sieve aperture presses concentric circles distribution.
The spherical crown with sieve aperture that this overflow pipe is arranged in overflow pipe, can effectively effectively isolate in overflow pipe with coarse grained liquid, prevent overflow pipe from running thick phenomenon, and sieve aperture increases sieve aperture dividing plate, particle quadratic distribution in the reverse flow of the cyclone overflow made, makes+80 object content in overflow reduce by 4% ~ 7%.
