Description
Technical field
The utility model relates to a kind of powder mixer, especially relates to a kind of powder high speed and precision mixer.
Background technology
In industry production such as electronics, chemical industry, medicine, food, battery material; Need two or more powders be mixed in a large number; The various mixers of extensive use; For example conical double ribbon revolves powder mixer, inclined bipyramid batch mixer, and multidirectional motion cone-type mixer or the like is though above-mentioned these mixers can effectively mix powder more than two kinds.But all be that weak point is arranged, for example, there is the dead angle in conical twin-screw mixer some areas, and the place, dead angle is mixed at the powder end; The uniformity is low, can only reach 95%, as for inclined bipyramid batch mixer; Though multidirectional movement mixer can reach higher mixture homogeneity, about 99%, this type mixer will add mill and be situated between when mixing---polyamine fat ball; Agate ball, stainless steel ball, zirconium ball etc. just can mix, but when mixing, no matter use which kind of ball, ball to grind mutually with ball; Club's wearing and tearing, the dry linting under the mill can pollute batch mixing, influences the quality and the performance of batch mixing.Above-mentioned up to now shortcoming prior art is not resolved as yet.
The utility model content
The utility model provides a kind of powder high speed and precision mixer; It mainly is to solve when the existing in prior technology mixer mixes to add polyamine fat ball, and mills such as agate ball, stainless steel ball, zirconium ball are situated between and just can mix, but when mixing, no matter use which kind of ball; Ball grinds with ball mutually; Club wearing and tearing, the dry linting under the mill can pollute batch mixing, influences the technical problem of quality and the performance etc. of batch mixing.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of powder high speed and precision mixer comprises base, and base is provided with vertical cylinder; The top of described vertical cylinder is provided with charging aperture, and the inside of vertical cylinder is provided with cup-shaped runner, is provided with the passage that can let powder pass through between cup-shaped runner and the vertical cylinder; The bottom of cup-shaped runner has through hole, and the below of cup-shaped runner is provided with fan, and cup-shaped runner, fan connect motor through transmission device; Motor is fixed on the base; Be fixed with the curved surface cylinder towards cup-shaped runner inwall through curved surface cylinder firm banking on the vertical cylinder, curved surface cylinder and cup-shaped runner inner surface leave the gap, and the edge of vertical cylinder bottom is provided with discharging opening.Fan in the pneumatic feeding system is fixed under the cup-shaped runner, with cup-shaped runner one superhigh speed rotation.Accurate mixer has a vertical cylinder, and the cup-shaped runner of a rotation, device power-up are equipped with in heart position therein; Drive cup-shaped runner by motor through transmission device and rotate at a high speed, open the lid on the charging aperture, the powder more than two kinds that will mix is put in the inner chamber of cup-shaped runner; When runner rotated at a high speed, powder received centrifugal action, and powder throws away from the through hole on the runner interior walls; The fan that the powder that throws away receives in the pneumatic feeding system purges, and powder is blowed to the cylindrical shell sky along the tube inwall, collides with the cover inwall of vertical cylinder; Drop in the inner chamber of the cup-shaped runner that is rotating; So repeat for N time, mixed powder is realized three-dimensional random motion, does not evenly have the dead angle thereby reach batch mixing.The operation principle of this mixed powder; Be to let mixed powder do three-dimensional random motion; Powder is mixed, and, need borrow in mills such as polyamine fat balls to be situated between unlike the inclined double-cone mixer; Could powder more than two kinds be mixed, the dry linting of so just having avoided mill to be situated between pollutes mixed powder.In order to eliminate the powder that reunion is arranged in the mixed powder, increased the mechanism that produces powerful dispersion shear ability in the mixer, it is realized with the mechanism that forms with the fixing curved surface cylinder that does not rotate of high-abrasive material making by the cup-shaped runner of rotation.When the powder that has reunion in the mixed powder is added to the inner chamber of plain cup wheel commentaries on classics; The powder conveying that the cup-shaped runner of rotation will have reunion is in the tapered region to the gap between curved surface cylinder and the cup-shaped runner inner surface; Through tapered region, the powder of reunion receives shearing force, and the reunion powder is disperseed; Go again to mix, thereby guaranteed the uniformity of mixing.
As preferably, be fixed with the adherent scraper that can powder be scraped through adherent scraper holder on the described vertical cylinder.If the dry powder that mixes makes moist, when mixing powder can internal chamber wall at cup-shaped runner on sizing, stop up the through hole on the wall of runner chamber, if sizing on the cavity wall, adherent scraper can scrape the powder that is bonded on the wall of chamber, proceeds to mix.
As preferably, be provided with the adjustment pad between described curved surface cylinder firm banking and the curved surface cylinder, the width in gap is 2-10mm.Owing to require the rerum natura of mixed material constant, promptly be that the granule-morphology of requirement powder is constant, grain diameter is constant, has therefore designed the adjustment pad of a cover scalable wedge gap according to the soft or hard of material rerum natura, just can reach the constant requirement of above-mentioned rerum natura.
As preferably, described vertical cylinder outside is provided with water jacket, has cooling water inlet, coolant outlet on the water jacket.Cooling water in the water jacket can vertical cylinder interior powder cool off, thereby preventing that a large amount of heats that produce when cup-shaped runner rotates at a high speed from heating material makes the powder modification.
As preferably, be provided with purging system in the described vertical cylinder, purging system is located at the top of cup-shaped runner.Pile up on the end face for powder static object in the mixer cylindrical shell of preventing not mix fully; Discharging is to mix in the powder that mixes; Influence the precision of mixture homogeneity; For this reason, on mixer vertical cylinder top cover, designed regularly purging system of a cover, the powder of piling up has been blown off in the runner inner chamber, mix again.So mixer mixture homogeneity of the present invention is very high, reaches more than 99.8%.
As preferably, the edge of described vertical cylinder bottom is an arc surface, and discharging opening is located on the arc surface, and discharging opening is provided with out funnel, goes out to be provided with the turnover panel that can seal discharging opening in the funnel, and turnover panel connects the discharging operating grip.
As preferably, described transmission device includes the belt pulley that is connected with motor, and belt pulley is through the belt transmission rotating shaft, and rotating shaft connects cup-shaped runner, and rotating shaft is provided with bearing.Pulley apparatus also can replace to other device that can drive shaft rotates such as gear drive.
Therefore, the utility model makes powder when mixing, realize three-dimensional random motion, does not have the dead angle thereby reach batch mixing; In the powder that mixes if the reunion powder is arranged; Can it be disperseed during mixing, remove the powder that falls and on resting, accumulate, to prevent that these powders from can not get mixing with purging; And influence the precision of mixture homogeneity; Do not need the mill of polyamine fat ball fire agate ball etc. to be situated between during mixing, mixing is to lean on the powder random motion to realize mixing, and prevents so mill Jie dry linting of producing pollutes powder.
