Description
Technical field
The utility model relates to a kind of reactor of belt stirrer for silver powder of preparing.
Background technology
Super fine silver powder is as the most frequently used electric slurry conductive material, not only be applied to traditional element electrode slurry, hydrid integrated circuit slurry, in new application, comprise that the aspect consumptions such as solar cell size, RFID silver slurry, PDP silver slurry are huge, therefore its technology of preparing has obtained tremendous development, liquid phase method, solid phase method and vapor phase method are all useful on research, but the most frequently used, most economical large scale production method remains liquid phase reduction.
Preparation method and the surface modification particle diameter mixing silver powder of a kind of surface modification particle diameter mixing silver powder that the applicant is 102407341A in the China Patent Publication No. of first to file, the preparation technology of its silver powder is with silver nitrate aqueous solution, containing the aqueous solution of PH conditioning agent, containing the alcoholic solution of surface modifier, containing the aqueous solution of reducing agent, mixes, and react in thering is the reactor of high-shear mixer, reduction generates silver powder.Because silver powder density is large, in course of reaction, as the silver powder of heavy phase, be constantly stacked into the bottom of reactor, each silver powder that makes thus reduction generate occurs each other bonding in banking process, cause the particle diameter of silver powder too large, cannot reach the requirement of configuration silver slurry.And the agitator of installing in existing reactor is all generally to rely on screw to stir, although this structure is comparatively simple, but the mixing power that screw produces is the outside pushing toward screw, and silver powder is piled up to bottom often and is longitudinal layered after reduction generates, therefore, screw cannot be realized silver powder is stirred rapidly.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existing in order to overcome prior art, and a kind of silver powder rapid stirring that can allow is provided, and causes a kind of reactor of preparing silver powder use belt stirrer of the mutual adhesion problem of silver powder to prevent silver powder from piling up.
For achieving the above object, the technical solution of the utility model is to include external kettle body, be located at the interior kettle in external kettle body, be located at the agitator in interior kettle, described agitator includes shaft, the upper end of described interior kettle is provided with sealing and is provided with kettle cover, on this kettle cover, be provided with dog-house, the upper end of described shaft is stretched out kettle cover and on it, is linkedly set with the shaft driving mechanism for driving shaft to rotate, it is characterized in that: the bottom of described shaft is provided with end stirring body, on this end stirring body, be provided with and be mutually four symmetrical end paddles of arranging to upper end perk of cross, the arcwall that the gabarit of described end paddle includes superposed vertical wall and is connected in vertical wall bottom, the mutual close neighbour of madial wall of described vertical wall and interior kettle, in oblique on the interior exterior feature of this end paddle, be provided with oblique transition wall, on described shaft, be also linkedly set with stirring wheel, this stirring wheel is positioned at the inner side of the oblique transition wall of end paddle, and this stirring wheel includes a discoid wheel body, the periphery inner periphery of described wheel body arranges a plurality of arc wing plates uniformly at intervals.
By this setting, when shaft rotates, drive end paddle and stirring wheel simultaneously, silver powder in interior kettle upwards seethes under the effect of end paddle, simultaneously, the mutual close neighbour of inwall due to vertical wall and agitator, the silver powder seething is under the compressing of the madial wall of interior kettle, to shaft direction, move, thereby enter into stirring wheel, and on the arc wing plate of stirring wheel, carry out multidirectional shearing and disperse, therefore, the utility model can make silver powder at interior kettle rapid stirring, can effectively prevent silver powder from piling up and cause into silver powder bonding problem mutually, improved the preparation quality of silver powder.
The width that the arcwall that is described end paddle is further set is from top to bottom and reduces gradually to arrange.By this setting, the arcwall of this end paddle forms the shape of the similar knife edge, can greatly reduce, during electric motor starting, the rotary resistance of heavy phase to end paddle in interior kettle, can motor burns starting moment, in addition, this arranges, and has also further improved the shear ability of end paddle to silver powder, has improved mixing effect.
Further arranging is that described shaft driving mechanism includes servomotor, on the output shaft of this servomotor, be linkedly set with the first belt pulley, the outer end of described shaft is linkedly set with the second belt pulley, between this first belt pulley and the second belt pulley, by belt transmission, connects.By this setting, realized the rotating drive to shaft.
Further arrange that to be described kettle cover offer support ring installing hole with respect to the outside of shaft, in this support ring installing hole, fixed support is provided with the support ring being sheathed on outside shaft, the bottom of this support ring is provided with shaft and rotates and paste the shaft sleeve part of joining, this support ring is provided with annular groove with respect to the upper inner wall of shaft sleeve part, and the space between this annular groove and shaft is disposed with rolling bearing, graphite packing and gland from top to bottom.By this setting, effective guarantee the sealing of shaft at upper cover place.
In sum, the utility model has the advantages that structure arranges rationally, and can effectively prevent silver powder from mutually piling up and the problem of the mutual bonding that causes, improved quality prepared by the electronation of silver powder.
