Floor projection is granulated the floor projection of every helix of machine rotor all away from 1.7 times of reasons for stirring tooth head diameter are approximately equal to
It is a comb;Because the shape for each stirring tooth head be cylinder or truncated cone shape, stir tooth collision carbon black when be carbon black
Averagely pushed aside to the both sides for stirring the tooth direction of motion;It follows that this comb only has agitating function without axial conveying function;
Carbon black axial direction conveying has the promotion of guide spiral plate rearward entirely;Get into smooth and necessarily cause material bed accumulation in granulating cylinder to thicken;
Blocked up material bed influences maximum to stirring tooth and this part carbon black in barrel gap;Because material bed is blocked up, this part carbon black obtains not
To the condition of " roll and be granulated along barrel ", mostly without being sufficiently stirred direct extruding and discharging;This is wet granulator product quality
It is not high, the main reason for especially fine powder content is exceeded.
The content of the invention
In order to solve the above problems, this programme tries to make each existing agitating function of tooth that stirs have conveying function again, to avoid
Material bed thickeies the adverse effect brought to being granulated quality.
The technical solution adopted for the present invention to solve the technical problems is:A kind of wet granulation motor rotor structure, by rotor
Axle, tooth base tube is stirred, A types are flat to stir tooth, and Type B is flat to stir tooth, nut, reinforcing bar and scraper composition;It is characterized in that:In the hollow shaft of armature spindle
Cylinder surface on weld it is numerous it is tapped stir tooth base tube, these stir tooth base tube by double helix arrange, helix angle α=
11.25 degree or so, on helix the two neighboring floor projection distance for stirring tooth center line be approximately equal to A types it is flat stir tooth correctly installation after
1.7 times of floor projection width;In stirring on tooth base tube for the corresponding bifilar helix being granulated below machine inlet, Type B is flat stirs for installation
Tooth, it is remaining to stir the installation of tooth base tube A types are flat stirs tooth;The setting angle of tooth flat horizontal surface is respectively stirred, except corresponding comminutor discharging opening center
Line is later and outer, and all flat horizontal surfaces for stirring tooth are all along hand of helix;Two helixes respectively stir tooth with a reinforcing bar flat
Waist location, on whole piece helix to stir tooth welding series winding integral;Two scrapers are arranged on the hollow beam barrel of armature spindle
Both ends.
Above-mentioned A types are flat to stir tooth and Type B is flat stirs tooth, it is characterized in that:Flat tooth lower half of stirring is full thread stud, and the first half is flat
Plate;Flat board front upper portion profile is arc line shaped, and the both ends facial contour in the vertical cross section of flat board is circular arc;The flat thickness for stirring tooth flat board
Degree takes traditional cylindrical to stir tooth tooth tip diameter size;Type B is flat to be stirred tooth sheet width more flat than A type to stir tooth sheet width slightly wide
A bit, other are identical.
Two helixes of this programme rotor are still a comb, still with agitating function;But stir the tooth direction of motion
Head-on except have a flat arc surface for stirring increment face and in addition to also have the flat plane for stirring tooth along helix, this just makes to stir tooth with stirring
The function of axial conveying is added while function.
This programme helix angle is half of traditional angle or so, and this has following benefit:First, in order to allow the flat tooth of stirring
Plane its entrance angle when colliding carbon black is a little bit smaller, it is easier to allows carbon black to be granulated along the flat tooth plane rolling that stirs, second, can mitigate
Rotor rotary resistance, third, rotor vibrations can be mitigated.
The beneficial effect of invention is to be changed to that there is the flat of suitably planar width to stir tooth due to traditional cylinder is stirred tooth,
Gear mutation and installing is stirred and both remained the agitating function of rotor, add the function of the axial conveying of rotor again, therefore make
Grain machine operating can avoid the formation of the excessive material bed of thickness;This point is to stirring tooth and this part carbon black meaning weight in barrel gap
Greatly;Due to being significantly thinned material bed, this part carbon black just can easily be stirred between cog ground connection agitation and get up and be rolled along barrel
Granulation ranks are added to, avoids material bed is blocked up from being forced to extruding without discharging is granulated, can effectively reduce the fine powder content of carbon black, it is stable
Improve the granulation quality and operating efficiency of comminutor.
