Background technology
The operation of extracting certain component with solvent from liquid mixture is called liquid/liquid extraction or solvent extraction.Extracting operation comprises two processes: the one, and material liquid fully mixes with extractant and contacts, and finishes the mixing mass transport process; The 2nd, the material behind the mixing mass transfer is under action of centrifugal force, because the difference of density can form light, heavy two-phase, reaches the purpose of separation, finishes separation process.Centrifugal extractor is exactly a kind of equipment of realizing above function.The rotary drum of centrifugal extractor all adopts the cylindrical tube structure in the prior art, and there is following drawback in this form:
1, the time of staying of material in rotary drum is limited.If increase the time of staying of material in rotary drum, must increase the height of rotary drum, this will increase manufacturing cost and difficulty of processing and operating cost.
2, because rotary drum is the cylindrical tube structure, diameter is the same up and down, and the suffered centrifugal force of the material of portion too within it.The computing formula of centrifugal force:
F＝mrω
2
Wherein, F: centrifugal force
M: the quality of material
R: material radius of living in
ω: the suffered angle of revolution of material speed
As seen, suffered centrifugal force and the radius of material is directly proportional.
And when extraction, in the bottom of the drum, light phase materials and heavy phase material are in the mixing mass transport process, do not need too big centrifugal force; And, enter separation phase along with material makes progress along rotatory drum wall gradually, need big centrifugal force that material is separated.So such running requires with top different centrifugal force is arranged in the bottom of rotary drum.Obviously, cylindrical tube structure rotary drum can not produce such effect.
3, material enters rotary drum by shell space, dependence be the self-priming effect that the impeller of rotary drum and housing bottom produces, and the self-priming effect that the cylindrical tube structure produces is relatively poor.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of conical barrate centrifugal extractor being provided.On the one hand, under the situation that does not change the rotary drum height, increase the time of staying of material in rotary drum; On the other hand, make rotary drum on short transverse, produce different centrifugal force, more adapt to the needs of extraction process.Simultaneously, increase its self-priming effect, make the easier rotary drum inside that enters of material.
Technical solution problem of the present invention adopts following technical scheme:
Conical barrate centrifugal extractor of the present invention is the rotary drum that is provided with blade in tubular shell, and each feed pipe and discharge nozzle are separately positioned on the sidepiece of tubular shell;
Design feature of the present invention is that described rotary drum is set is the Rotary-table with tapering, and described Rotary-table is little for going to the bottom, upper base is big.
Design feature of the present invention also is:
Described blade is set has the tapering that matches with described rotary drum.
It is with the direct-connected structure of directly driving of shaft coupling that the output shaft of drive motors and the central rotating shaft of described rotary drum are set.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention adopts the drum structure with suitable tapering according to the density of material weight phase, and under the situation of rotary drum equal height, rotary drum (cone-element) can effectively increase the time of staying of material in rotary drum, and material can fully be mixed and separate;
2, the present invention adopts the rotary drum (cone-element) structure, and rotary drum increases gradually from the bottom to the top radius, and the centrifugal force that should bear mutually is also big more.Like this, the centrifugal force that material bears in the bottom of the drum is littler, just in time helps the mixing and the mass transfer of mutually light and heavy phase; And on rotary drum top, diameter increases, and centrifugal force also increases, and just in time helps the separation of mixed material.Rotary drum (cone-element) makes rotary drum produce different centrifugal force on short transverse, more adapts to the extraction process needs.
3, the present invention adopts the rotary drum (cone-element) structure, by being arranged on the blade wheel structure of rotary drum (cone-element) and housing bottom, can produce bigger self-priming effect, easier suction material.
4, rotary drum of the present invention inside has and the match blade of tapering of rotary drum, can prevent effectively that material from producing skidding in rotary drum, guarantees that material and rotary drum rotate synchronously.
5, rotary drum (cone-element) structure of the present invention, mode is simple, compact conformation.Too many cost needn't be increased, but bigger economic benefit can be produced.Directly drive rotary drum by motor direct connection form and be rotated, connect by shaft coupling between motor shaft and the rotary drum, the problems such as wearing and tearing pollution of having avoided belt transmission to bring.
