Specific embodiment:
For the technical characterstic of this programme can be clearly described, below by specific embodiment, and combine its accompanying drawing, to this reality
It is described in detail with new.
As shown in figure 1, a kind of processing modified abrasive disk of CNT, set including a closing on workbench 16
The grinding chamber 1 put, is provided with discharging opening 15 in the side of grinding chamber 1, is movably equipped with a hollow rotating shaft respectively at the two ends of grinding chamber 1
2 and mobile shaft 3, the middle part that one end of hollow rotating shaft 2 is located at the fixing abrasive disk 4 be vertically arranged in grinding chamber 1 with is connected,
It is provided with a through hole 5 at the middle part of fixing abrasive disk 4, the inside of hollow rotating shaft 2 is connected with through hole 5, one end position of mobile shaft 3
The middle part of the mobile abrasive disk 6 being oppositely arranged with fixing abrasive disk 4 being vertically arranged with grinding chamber 1 is connected, and movement is ground
The direction of rotation of mill 6 is contrary with the direction of rotation of fixing abrasive disk 4, the other end of hollow rotating shaft 2 be located at grinding chamber 1 outer with the
One rotating driving device is connected, and the other end of mobile shaft 3 is located at outside grinding chamber 1 and its end and axial movement driving means phase
Even, the mobile shaft 3 outside grinding chamber 1 is connected with the second rotating driving device.
Described axial movement driving means include the slide plate 8 on workbench 16, and bearing block is passed through in mobile shaft 3 end
7 are movably arranged on slide plate 8, and the bottom activity of slide plate 8 is placed in the slideway 9 being located on workbench 16, is provided with spiral shell on slide plate 8
Stricture of vagina through hole, is provided with the leading screw 14 matching with tapped through hole in tapped through hole, and one end of leading screw 14 is connected with the second motor 13.
Described second rotating driving device includes the driven gear 10 on mobile shaft 3, in mobile shaft 3 side
Workbench 16 is provided with the first motor 11, and the main shaft of the first motor 11 is provided with the driving gear being meshed with driven gear 10
12, the width of driven gear 10 axial direction is more than the width of driving gear 12 axial direction.
Fixing abrasive disk 4 surface relative with mobile abrasive disk 6 is provided with rollet.
During grinding, start driving means and the first motor 11, the mixture containing CNT and solvent passes through hollow turn
Axle 2, the through hole 5 of fixing abrasive disk 4 enter in the gap between the fixing abrasive disk 4 of grinding chamber 1 and mobile abrasive disk 6, according to
Fluid mechanics principle, is accelerated to the speed the same with abrasive disk near the mixture grinding panel surface with the rotation of abrasive disk
Degree, and then speed, less than the speed of abrasive disk, so can be internally formed speed in mixture away from the mixture grinding panel surface
Degree is poor, thus producing relative motion between mixture, produces interaction force, occurs mutually to collide, make between CNT
Snarly CNT breaks apart from relatively weaker position, thus solving the agglomeration traits of CNT.Fixation is ground
The difference of direction of rotation of mill 4 and mobile abrasive disk 6 and the projection or the groove that grind panel surface, all can make between mixture
Form more violent turbulent flow, thus a probability only step of collision increases, thus realizing more preferable dispersion effect.This utility model
Using process for dispersing different from traditional mechanical dispersion or ball milling, predominant intermolecular forces are between CNT and CNT
Interaction force, equipment itself simply accelerates to mixture, therefore the active force that equipment is born will be much smaller than tradition dispersion
The active force that mode direct effect is born on the carbon nanotubes, thus the rotating speed of abrasive disk can accomplish very high, abrasive disk straight
In the case that footpath is sufficiently large, the mixture of marginal position can accelerate to very high speed, thus producing enough power to make
CNT is pulverized from weak position.In the presence of High Speed Turbulent, the aggregate of CNT bears not from prolonging first
The long chain interruption of rule, the part then projecting then progressively can be corrected because bearing more active forces, eventually tends to ball
Shape CNT tennis.With the lifting of degree of grinding, the gap between two abrasive disks can be reduced further, improve grinding chamber
Flowing velocity within 1, thus obtain smaller size of CNT tennis further.Reduce the gap between two abrasive disks
When, start the second motor 13 and drive leading screw 14 to rotate, with the rotation of leading screw 14, slide plate 8 is mobile along slideway 9, thus realizing
Mobile shaft 3 and the driven gear 10 being connected with mobile shaft 3 and mobile abrasive disk 6 are moved, and realize two grinding dish gaps
Reduce.Because the width of driven gear 10 axial direction is more than the width of driving gear 12 axial direction, driven gear 10 and active after moving
Gear 10 still can normally engage the transmission carrying out power.
With the crushed dispersion of CNT aggregate, the viscosity of mixture can rise, when mixture is in sticky g., jelly-like
When, most of CNT aggregate is opened, and the substitute is scattered carbon nano-sized carbon netted spheroid, ground carbon
Nanotube flows out from discharging opening 15, after being then passed through being spray-dried, obtains carbon nanoclusters pipe netted spheroid.Keeping carbon nanometer
While pipe high conductivity, decrease the CNT stretching out, it is to avoid CNT tangles mutually, form aggregate, significantly change
It has been apt to the processing characteristics of CNT.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement made etc., should be included in this utility model
Protection domain within.
This utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
