Description

The adjustable waterpower rotational flow device
Technical field
The utility model relates to a kind of hydrocyclone, specifically, Gu Gu relate to a kind of can regulate split ratio, that have the runner feeding manner, be the adjustable waterpower rotational flow device continuous phase carrier, that be used for liquid/separation or solid/classification, sorting with liquid.
Technical background
China's utility model patent number 02221295.7 discloses a kind of hydrocyclone that can regulate split ratio, as shown in Figure 1, comprises overflow pipe 10, eddy flow cylindrical shell 20, underflow pipe 30, adjusting rod 40, butterfly type cup 50.
Under certain pressure, processed suspension is done the high-speed rotational motion after tangentially entering cyclone cylinder part by charging aperture 210, Gu Gu under the effect of centrifugal force field, finish liquid/separation or solid/classification process rapidly, by overflow pipe 10 discharge contain that granularity is thin, density is than the low concentration overflow product of granule, discharge by underflow pipe 30 and contain that granularity is thick, the high-concentration underflow product of density larger particles.
In hydrocyclone, there is flow boundary layer in the wall place, and the branch of following interlayer of lid and limit wall boundary layer is arranged.The boundary layer has " shielding " effect to particle, and in a single day particle enters the boundary layer and just be difficult to break away from its " constraint " again.So, run thick phenomenon with the mobile generation overflow of the following interlayer of top cover, the flowing of lagging edge wall boundary layer then produces underflow and presss from both sides thin phenomenon.Overflow is run thick and underflow folder and is carefully all made the separating of cyclone, classification performance reduction, is one of key factor that influences cyclone efficient.
The split ratio of hydrocyclone, i.e. the ratio of underflow product flow and feed rate is to influence that cyclone separates, another key factor of classification efficiency.In the production reality, conventional hydrocyclone is regulated the split ratio of hydrocyclone usually by the underflow pipe 30 of changing different latus rectums, operates cumbersomely, particularly is difficult to remove from cyclone body through the long-time back underflow pipe 30 that uses.
In the hydrocyclone, the interior eddy flow that flows to overfall extends near the underflow opening always, make separated in the inside and outside eddy flow near the underflow opening, the part blending takes place in the particle of classification again, reduced separation, the classification efficiency of conventional hydrocyclone.
The cyclone of said structure is by increasing adjusting rod 40 and butterfly type cup 50 these two parts, though reach the purpose of regulating the cyclone split ratio, but under the high speed that thin-walled butterfly type cup 50 is near the high concentration coarse granule stream cyclone underflow opening for a long time in this device is washed away, very easily wearing and tearing need frequently to change this part in the real work.
Summary of the invention
The purpose of this utility model provides a kind of adjustable waterpower rotational flow device, can carry out the adjusting of split ratio easily, and the inhibition underflow opening separates, the blending of graded particie; Simultaneously, this hydrocyclone has the runner feeding manner, can reduce the chance that particle enters the boundary layer, run thick and underflow presss from both sides thin phenomenon thereby suppress in the conventional hydrocyclone ubiquitous overflow, the raising hydrocyclone is to separation, the classification performance of particle.
To achieve these goals, adjustable waterpower rotational flow device of the present utility model comprises eddy flow cylindrical shell, feed pipe, overflow pipe, adjusting rod; Wherein, the eddy flow cylindrical shell comprises trunk portion, cone portion; Feed pipe is arranged at the trunk portion upper end, and is attached thereto logical; Overflow pipe is arranged at the trunk portion upper end, and is attached thereto logical; The overflow pipe outlet connects the overflow extension tube attached; Adjusting rod is installed in the eddy flow cylindrical shell; Also be provided with a cone governor, this cone governor is sheathed on the adjusting rod bottom; The outlet of underflow is the following outlet of cone portion in the utility model.
Further, described feed pipe is provided with at least two passages;
Two passages of described feed pipe become inside and outside be provided with or about, upper and lower settings;
Described feed pipe becomes tangential and is communicated with described trunk portion; Make the flow energy loss minimum.
The makeup of the imports form of runner charging makes the part neat liquid enter cyclone by the outer flow passage of feed pipe, and suspension to be separated or classification then enters cyclone from the inner flow passage of feed pipe.Because the wall boundary layer is two-way to " shielding " effect of particle, the neat liquid of being come in by outer flow passage forms the neat liquid boundary layer at cyclone inwall place, such neat liquid boundary layer equally also has " shielding " effect to the particle outside the boundary layer, make the particle of coming in suspension be difficult to enter in the boundary layer again by inner flow passage, and can only issue in the effect of the inherent centrifugal force field in main flow zone estranged from, classification, run thick and underflow presss from both sides thin phenomenon thereby can suppress in the conventional hydrocyclone ubiquitous overflow, the raising hydrocyclone is to the separation of particle, classification performance.
Again, described cone governor top is the conical surface for the curved surface bottom;
The tapering of the described cone governor conical surface is greater than the tapering of cyclone cone portion; The diameter of bore of cone governor is fixed with the adjusting rod interference fit less than the external diameter of construction section on the adjusting rod;
Described cone governor is made by polyurethane material.
Further, also be provided with spring bearing, this spring bearing is fixed in the cone portion lower end, and adjusting rod one end is installed in this spring bearing, to prevent the impact lower swing of adjusting rod at fluid;
Also be provided with nut, this nut is fixed on the overflow extension tube attached, and adjusting rod cooperates with nut thread.
Described trunk portion, feed pipe, overflow pipe are integral structure.
In the time will regulating the split ratio of cyclone, by the turn adjusting rod adjusting rod and cone governor are moved up and down in cyclone, can regulate the split ratio of cyclone easily then thereby realize regulating cyclone underflow outlet flow area.
Compare with existing hydrocyclone, the utlity model has following advantage:
1. cone governor has limited interior eddy flow near underflow opening, thereby reaches steady flow, reduces the cyclone energy consumption, improves the purpose of its separation, classification performance; Adjusting rod has been avoided the swing of adjusting rod by setting up spring bearing.
2. be neat liquid in the wall boundary layer, reduced in the conventional hydrocyclone the ubiquitous overflow that causes by the wall boundary layer and run thick and underflow presss from both sides thin phenomenon, thereby improved separation, the classification performance of hydrocyclone particle;
3. owing to be neat liquid in the wall boundary layer, its viscosity is less than the viscosity of suspension, thereby can reduce the interior fluid resistance loss of hydrocyclone, cuts down the consumption of energy;
4. can regulate the split ratio of cyclone easily by the turn adjusting rod,, thereby also can further improve its separation, classification efficiency so that it carries out optimum operating mode control according to different charging situations;
5. cone governor is avoided defective easy to wear by the good polyurethane material manufacturing of anti-wear performance;
6. by the split ratio of regulating cyclone, the cross sectional shape of the interior outer flow passage of feed pipe and the flow velocity in flow area and each runner, can make cyclone be applicable to separation, the classification process of various particles.
