Description
Technical field
The present invention relates to a kind of classifying cyclone and cyclone separator, specifically a kind of cyclone based on overflow pipe
On-line control device.
Background technology
Cyclone because of simple in construction, equipment cost is low, disposal ability is big etc., and advantage is widely used in liquid heterogeneous mixed
The separation of compound.Strong rotational shear turbulent motion is produced from cyclone periphery after mixed liquor tangentially enters in cyclone,
There are density (granularity) difference between due to variable grain, the size such as its suffered centrifugal force, gravity, fluid drag is also different.
The big particle of major part density (granularity), under the effect with gravity for the centrifugal force, is thrown to eddy flow wall, by bottom head piece row
Go out.Major part density (granularity) little particle rotation to a certain extent after flow through overflow pipe with vortex on secondary and discharge.Therefore, overflow
Tube flowing structure has important influence for cyclone sorting, grading effect.
Many scholars once did the research adjusting overflow pipe structure, and what patent announcement number was CN 203124134 U is " a kind of
Novel adjustable concentric double overflow tubular type three products hydraulic rotational flow device ", it can regulate medial and lateral overflow according to the difference of operating mode
The size of pipe diameter, and the length of inside and outside overflow pipe insertion cylinder, thus improve partition size and the sorting effect of cyclone
Rate." heavy medium cyclone of online adjustable overflow pipe " that patent announcement number is CN 203124133 U, utilizes hydraulic power to drive
Dynamic overflow pipe carries out depth location regulation, can adjust the dense media of the online adjustable overflow pipe of separating density according to demand in real time
Cyclone.Both the above method can realize the adjustable online of cyclone overflow pipe insertion depth, but they are not but right
The flow regime of overflow pipe internal flow is adjusted.
Patent publication No. is " a kind of eddy flow and jet inflation method and the device thereof " of CN 101474599A, utilizes and overflows
The hybrid blade of flow tube centerline axis parallel will become four bursts of flow of slurry from overflow pipe rotation ore pulp force-splitting out so that it is volume
Enter air and strongly mix with air, forming airwater mist cooling mixed flow, and carry a large amount of kinetic energy entrance jet pipe.Fully
The remaining kinetic energy utilizing cyclone overflow achieves jet, saves energy of the impinging jet.Though this device changes overflow tube fluid
Liquid form, but the continuously adjustabe to this process can not be realized.
The one " adjustable hydraulic swirler " that patent announcement number is CN 2628149Y, utilizes adjusting rod and cone governor to exist
Move up and down in cyclone and regulate the split ratio of cyclone, the flow velocity feeding in simultaneously changing each runner, make cyclone fit
Separation classification process for various particles.This cyclone is to carry out continuously adjusting changing to the fluid flowing in cyclone
Its split ratio, and the fluid flowing in overflow pipe is still not carried out continuously adjustabe.
Content of the invention
For the defect overcoming above-mentioned prior art to exist, the present invention provide a kind of simple to operate, efficiency high based on overflowing
The cyclone on-line control device of flow tube.By this device under cyclone normal running conditions, effective on-line control overflow pipe
The size of flow section, the distribution changing cyclone interior flow field and speed, especially improve the Fine grain content effect of 0-3mm
Really, it is achieved that cleans ash is adjustable online with productivity.
The present invention can be reached by following measures:
A kind of cyclone on-line control device based on overflow pipe, it is characterised in that: described overflow pipe periphery be serially connected with
The epimere overflow chamber of dividing plate separation and hypomere cylinder, and blading is installed in overflow pipe, by overflowing blading
The control of the insertion depth in flow tube, and then affect the flow field characteristic of cyclone internal flow, it is achieved to cyclone grading
Granularity or the on-line control of product ash content；
Described blading is to be made up of the blade of three or more than three, and vertical direction and centerline axis parallel, leaf
Piece inclined angle alpha is 0 90 °, is spaced identical between every adjacent blades.
In technique scheme, the upper end of described blading is connected with leading screw, and regulates blade by rotation hand wheel
Insertion depth in overflow pipe for the device；The diameter of overflow chamber's outlet that described overflow chamber is arranged is more than the diameter of overflow pipe；Institute
Stating the feeding mouth arranging on hypomere cylinder is the tangential feeding mouth of rectangle；It is provided with the tangential feeding mouth of rectangle on described hypomere cylinder；
The adjustable range of described blading insertion depth is overflow pipe bottom to the upper end of overflow pipe.
Realize above-mentioned the provided online tunable arrangement of a kind of cyclone based on overflow pipe of the present invention, with prior art phase
Ratio, is capable of under cyclone normal running conditions, effective on-line control overflow pipe size, changes cyclone interior flow field and divides
Cloth, it is achieved on-line continuous obtains the head coal product of different grain size and ash content.And it is greatly saved manpower and material resources.
