Description
Technical field
The present invention relates to a kind of centrifugal extractor.
Background technology
The course of work of centrifugal extractor is broadly divided into two parts：I.e. mixing mass transport process and centrifugal separation processes, wait to mix
The two kinds of liquid closed complete mixing under the turning effort of the rotary drum or blade of centrifugal extractor, complete mixed mixed liquor and enter
Enter rotary drum, rotation is so as to produce centrifugal force at a high speed under the drive of rotary drum, and the big liquid of density is outside under the influence of centrifugal force
Aggregation, the small liquid of density is inwardly assembled, and two kinds of liquid can gradually be layered and form an interface, and the density in outside is larger
Liquid discharges extracter by heavy out, and the less liquid of density in inner side discharges extracter by light phase export, so that
Complete separation process.
The shortcoming of this traditional centrifugal extractor is, because heavy phase pod apertures and flow control hole are axially to set
Put, after electric motor starting, the mixing of two phase materials and separation, and very rapidly rise from rotary drum, heavy phase is quickly from heavy phase pod apertures
And flow control hole is flowed directly out, cause heavy phase residence time in rotary drum short can not separate very well.
And when main shaft drives the rotary drum of its end to rotate at a high speed, Centrifugical extraction machine vibration can be caused, rotating speed more it is big then
Vibration is more serious, so as to limit the rotating speed of rotary drum so that the mixing of weight phase and separating effect are not good enough.
The content of the invention
The technical problems to be solved by the invention are：A kind of small, good separating effect centrifugal extractor of vibration is provided.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of centrifugal extractor, including frame,
Frame is provided with the cylindric feeding cylinder that axis is vertically set, and feeding cylinder enters provided with light-phase liquid import and heavy-phase liquid
Mouthful, upper rack is provided with motor, and the force-output shaft of motor is connected by shaft coupling with rotary shaft, the rotary shaft other end
Penetrate in feeding cylinder and be connected with feeding cylinder lower end, rotary drum, rotary drum are arranged with the part being located in rotary shaft in feeding cylinder
Bottom is provided with compound import, rotary shaft in rotary drum at compound import provided with charging impeller, and rotary drum top is under
Light phase separation chamber and heavy phase separation chamber are up sequentially provided with, light phase separation chamber bottom is provided with light phase import, and light phase separation chamber is with turning
It is communicated with being sequentially provided with ring-type above feeding cylinder in the heavy phase import of rotary drum inner chamber and heavy phase separate type, frame between drum wall
Light phase collecting chamber and ring-type heavy phase collecting chamber, light phase separation chamber is provided with the light phase export that is connected with light phase collecting chamber,
Light phase collecting chamber is provided with light phase outlet, and heavy phase separation chamber is provided with the heavy out being connected with heavy phase collecting chamber, heavy phase
Collecting chamber is provided with heavy phase outlet.
As a kind of preferred scheme, the part that rotary shaft passes feeding cylinder is provided with what is be engaged with feeding cylinder outer bottom
Positioning component, the bottom of feeding cylinder is provided with connecting seat, and rotary shaft end is connected by bearing block with connecting seat.
As a kind of preferred scheme, locating ring is provided with the top of heavy phase separation chamber, locating ring is provided with out liquid plate, goes out liquid plate
If provided with do on liquid circular hole, locating ring go out liquid plate top removably provided with block part go out liquid circular hole go out liquid gear
Ring, locating ring, which is provided with, pushes down out the cover plate of liquid baffle ring, the rotary shaft from cover plate, go out liquid plate in pass through, the heavy out
It is radially arranged on the cover board along rotary drum.
As a kind of preferred scheme, feeding cylinder bottom is provided with blow-off pipe.
The beneficial effects of the invention are as follows：Penetrated in feeding cylinder and be connected with feeding cylinder lower end due to the rotary shaft other end,
Reduce the vibration of rotary drum so that the rotating speed of rotary drum can be higher, improve mixing and the separating effect of weight phase.
Due to being provided with charging impeller in rotary shaft at compound import in rotary drum, charging impeller can be mixed well
The material of two-phase is closed, and can prevent mixed liquor from directly rising to light phase collecting chamber along rotary shaft.
The part that rotary shaft passes feeding cylinder is provided with the positioning component being engaged with feeding cylinder outer bottom, the bottom of feeding cylinder
End is provided with connecting seat, and rotary shaft end is connected by bearing block with connecting seat so that the installation positioning of rotary drum is more easy.
, can basis due to removably going out liquid baffle ring provided with block that part goes out liquid circular hole going out liquid plate top on locating ring
Different select of material suitably goes out liquid baffle ring, goes out liquid speed degree to adjust heavy phase, so as to reach more preferable separating effect.
Because heavy out is radially arranged on the cover board along rotary drum, that slows down heavy-phase liquid goes out liquid speed degree so that in mixed liquor
Light phase thing separation it is more abundant, reduce entrainment, raising separating effect.
