Superfine powder refers to that yardstick is between molecule, and between atom and bulk material, micron and nano level minute solid particles, comprise metal, the multiple material particle such as nonmetal, organic and inorganic and biological.Superfine powder and densified be one of study hotspot of Material Field, compared with conventional material, superfine powder has the physics of a series of excellence, chemistry and surface and interface character.
At present, the stage division of superfine powder has been reported, and the state according to point stage material can be divided into dry classification, wet classification and supercritical fractionation.According to the difference in the classification field of force, gravitational field classification, centrifugal force field classification, inertial force field classification, electric field force classification, magnetic field force classification, the classification of the thermal gradient field of force and chromatographic fractionation etc. can be divided into again.According to the different qualities of superfine powder, the various suitable field of force is utilized to carry out effective classification to superfine powder, to obtain the raw material of different-grain diameter.But existing stage division cannot realize continuous operations mostly, and before carrying out classification to superfine powder, the superfine powder synthesized by chemical reduction method is all needed through following process process such as super-dries, very easily agglomeration occurs, and is unfavorable for classification.
Utility model content
The utility model, for the deficiency proposed in background technology, provides one effectively can carry out classification to superfine powder, enables superfine powder reach the device of required each type product.
Technical solution of the present utility model:
A kind of grading plant of superfine powder, it is characterized in that: comprise stirred tank, the shaft be arranged in stirred tank, measuring pump, supercentrifuge and collection still, described measuring pump charging aperture is connected with bottom stirred tank by PU pipe, measuring pump discharging opening is connected with high speed centrifugation machine inlet capable by PU pipe, and supercentrifuge discharging opening is connected with collection still by stainless steel flexible hose.
Described shaft is connected with motor.
Described supercentrifuge is tubular-bowl centrifuge.
The beneficial effects of the utility model: the utility model adopts supercentrifuge to carry out classification to superfine powder slurry, not only simple to operate, classification efficiency is high but also product after classification is pollution-free, fully ensure that the quality stability of classification powder.
Accompanying drawing explanation
Fig. 1 is powder classification device structural representation in the utility model.
1-stirred tank, 2-shaft, 3-measuring pump, 3-1 measuring pump charging aperture, 3-2 measuring pump discharging opening, 4-supercentrifuge, 4-1 high speed centrifugation machine inlet capable, 4-2 supercentrifuge discharging opening, 5-collect still, 6-PU pipeline, 7-motor, 8-stainless steel soft pipeline.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described further.
A kind of grading plant of superfine powder, comprise stirred tank 1, the shaft 2 be arranged in stirred tank 1, measuring pump 3, supercentrifuge 4 and collect still 5, measuring pump charging aperture 3-1 is connected with bottom stirred tank 1 by PU pipe 6, measuring pump discharging opening 3-2 is connected with high speed centrifugation machine inlet capable 4-1 by PU pipe 6, supercentrifuge discharging opening 4-2 is connected with collection still 5 by stainless steel flexible hose 8, shaft 2 is connected with motor 7, and supercentrifuge 4 is tubular-bowl centrifuge.
Specific operation process: a collection of 100kg is made into the not classified extra-fine nickel powder (300nm) after slurry, is divided into 2 batches, every batch of 50kg high speed centrifugation classification process.
Embodiment 1 (batch one)
(1) starter motor, shaft starts to rotate, and is added in stirred tank by extra-fine nickel powder slurry 50kg and stirs;
(2) start supercentrifuge, after the rotating speed of supercentrifuge reaches 15000 revs/min, start measuring pump and start charging;
(3) extra-fine nickel powder slurry enters supercentrifuge classification through measuring pump, and overflow enters from supercentrifuge outlet flow source and collects still, collects nickel powder 36.48kg;
(4), after classification terminates, the powder on cleaning supercentrifuge rotary drum is gone forward side by side collection, collects the nickel powder 13.47kg on rotary drum.
Embodiment 2(batches two)
(1) starter motor, shaft starts to rotate, and is added in stirred tank by extra-fine nickel powder slurry 50kg and stirs;
(2) start supercentrifuge, after the rotating speed of supercentrifuge reaches 15000 revs/min, start measuring pump and start charging;
(3) extra-fine nickel powder slurry enters supercentrifuge classification through measuring pump, and overflow enters from supercentrifuge outlet flow source and collects still, collects nickel powder 37.25kg;
(4), after classification terminates, the powder on cleaning supercentrifuge rotary drum is gone forward side by side collection, collects the nickel powder 12.69kg on rotary drum.
Grain size analysis test is carried out to the original nickel powder of the overflow nickel powder in embodiment 1 and embodiment 2, the nickel powder on rotatory drum wall and not classified process and BET detects, its result respectively as shown in Table 1 and Table 2:
The Laser particle-size distribution test result of table 1 powder
The BET testing result of table 2 powder
As can be seen from Table 1 and Table 2, the extra-fine nickel powder that the extra-fine nickel powder collected through centrifuge outlet overflows, rotatory drum wall are collected is compared with the original nickel powder of not classified process, the former powder of not classified process is not due to through dispersed with stirring, intergranular often soft-agglomerated, add that itself particle size distribution is comparatively wide, so Laser particle-size distribution detection numerical value is larger; Extra-fine nickel powder overflow portion is made up of the particle diameter smaller portions in former powder, and obtains good dispersion, thus its Laser particle-size distribution and droplet measurement numerical value all little than the numerical value of former powder; The extra-fine nickel powder that rotatory drum wall is collected is made up of particle diameter major part in former powder, and Laser particle-size distribution and droplet measurement numerical value are all greater than the numerical value of former powder.
adopt the extra-fine nickel powder grading effect of the utility model device classification obvious, the dispersity of nickel powder of overflow is good.
To sum up, the utility model produces a desired effect.
