Accompanying drawing explanation
Fig. 1 is the structural representation of film dispersion machine of the present invention.
Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, the most right
The detailed description of the invention of the present invention is described in detail, and makes the above and other purpose of the present invention, feature and excellent
Will definitely become apparent from.The part that reference instruction identical in whole accompanying drawings is identical.The most deliberately by than
Example draws accompanying drawing, it is preferred that emphasis is illustrate the purport of the present invention.
The film dispersion machine of the present invention substantially can be divided into grind section and Matter Transfer portion, and it is right that grind section is mainly responsible for
CNT or the grinding of Graphene, circulation portions is then responsible for that Matter Transfer is sent into grind section thus can realize thing
The grinding repeatedly of material, so that material reaches the particle diameter specified.
Refer to Fig. 1, a kind of film dispersion machine, including grinding chamber 18, be provided with dynamic in described grinding chamber 18
Mill 4 and static cutting disk 5, described movable grinding disc 4 is by rotating shaft and the grinding motor being arranged at outside grinding chamber 18
1 is connected, and carries out sealing gland between rotating shaft and grinding chamber 18, and sealing gland can use labyrinth air seal circle/pad existing,
Being provided with material hole in the middle of described static cutting disk 5, described material hole is by the bottom of the first circulation pipe 7 with storage tank 8
Connection, described first circulation pipe 7 is provided with circulating pump 6, and described grinding chamber 18 is by the second circulation pipe 11
Connecting with the top of described storage tank 8, be provided with agitator 13 in described storage tank 8, agitator 13 is by setting
The stirring motor 12 being placed in storage tank 8 top drives, and the top of described storage tank 8 is provided with hopper 14, treats
Grinding material enters in storage tank 8 from hopper, and storage tank 8 is a hermetically sealed can, and top is provided with vacuum pumping pump
15, the air in storage tank 8 can be extracted out by vacuum pumping pump 15, permissible by gas atmosphere inlet 19
It is passed through protective gas, is so possible to prevent the oxidation of material in process of lapping.Further, also include controlling
Device 10 and flow sensor 9, controller 10 respectively with described grinding motor 1, circulating pump 6, static cutting disk 5
It is connected with sensor 9.
Further, grinding chamber 18 is made up of upper shell 17 and lower shell 3, upper shell 17 and lower shell 3
Upper and lower two parts overlap on together, form an airtight cavity, when gap a changes up and down, by overlapping
Part compensates, and upper shell 17 is fixed cylinder, and lower shell 3 can move up and down relative to upper shell 17,
Described static cutting disk 5 is arranged in described lower shell 3, and lower shell 3 adjusts motor 16 with gap and is connected, and passes through
Gap adjusts motor 16 and drives lower shell 3 to move up and down, thus adjusts between movable grinding disc 4 and static cutting disk 5
Gap.Adjust gap a by adjustment cylinder can farthest reduce grinding component (movable grinding disc 4
With static cutting disk 5) impact, owing to grinding component does not do movement relative to cylinder, such that it is able to prevent its machinery
Abrasion, damage, increase service life.
In the present invention, treating material is deposited in storage tank 8, by circulating pump 6 by storage tank 8
Material is delivered to static cutting disk 5, enters from the material hole of static cutting disk 5 bottom two mill intermediate space a, static cutting disk
5 rotate in the middle part of process of lapping, but static cutting disk 5 can fluctuate, thus adjust gap a, due to
Static cutting disk 5 does not rotates, and such static cutting disk 5 only moves up and down, and this regulative mode makes equipment not
Easily be damaged (if adjusting movable grinding disc 4, the rotating shaft of movable grinding disc to move up and down, simultaneously need to rotate, this
It is more complicated that sample allows for guiding mechanism, is susceptible to damage).Gap a is by can be by the journey in controller 10
Sequence makees fluctuating of respective range according to the granularity of material.Movable grinding disc 4, with the linear speed of 50-100m/s, is made
Constant runs up, and material passes through two abrasive disk spaces, is sheared by the effect of high speed centrifugation power, grinds,
Being back to after grinding in storage tank 8, after completing a cycle grinding, material is sent into and is ground by circulating pump 6 again
In mill chamber 18, so go round and begin again, until reaching to set granularity.Agitator 13 in process of lapping
For material stirring is mixed.
Controller 10 controls circulating pump 6 according to the signal gathered described in sensor 9, grinds motor 1 and quiet mill
Dish 5.Specifically, sensor 9 can include that flow sensor and particle size sensor, controller 10 receive
After raw meal particle size detected by particle size sensor, adjust the position of static cutting disk 5, Mei Yizhou according to detected value
After phase is ground, raw meal particle size all can diminish, and controller 10 controls static cutting disk 5 and is gradually increasing, thus reduces
Gap a so that material is by the most finely ground, and controller 10 can also receive the stream that flow sensor is sent here
Amount signal, flow signal indicate entry into material in grinding chamber 18 number, the thing in entering grinding chamber 18
When material exceeds setting range or exceedes disposal ability, controller 10 reduces the rotating speed of circulating pump 6, thus reduces
Enter the material in grinding chamber 18, or controller 10 is when detecting that flow increases, improve and grind motor 1
Rotating speed, such that it is able to process more material.May insure that entrance is ground by the above-mentioned adjustment of controller 10
Inventory in mill chamber 18 adapts with the disposal ability of grinding chamber 18, it is ensured that enter the thing in grinding chamber 18
Material is all fully ground, by constantly adjusting gap a, it is ensured that material to be ground reaches to set granularity.Enter
One step, controller 10 can also detect the load (power output) grinding motor 1, and load can basis
The voltage of motor is calculated with parameters such as electric currents, and these belong to prior art and repeat no more.When electricity being detected
When the load of machine exceedes the threshold value of setting, at this moment indicating, enter the material between mill more, particle diameter is relatively big,
Controller 10 increases gap a by adjusting motor 16, otherwise then reduces gap a.The present invention uses mill
Grind, it is to avoid ball material separation problem, and the amount every time ground is the least, thus avoids putty.
Elaborate a lot of detail in the above description so that fully understanding the present invention.But more than retouch
Stating is only presently preferred embodiments of the present invention, and the present invention can be to be much different from other side described here
Formula is implemented, and therefore the present invention is not limited by disclosed above being embodied as.The most any it is familiar with this area
Technical staff, without departing under technical solution of the present invention ambit, may utilize method and the skill of the disclosure above
Technical solution of the present invention is made many possible variations and modification by art content, or be revised as equivalent variations etc.
Effect embodiment.Every content without departing from technical solution of the present invention, according to the present invention technical spirit to more than
Any simple modification, equivalent variations and the modification that embodiment is done, all still falls within technical solution of the present invention protection
In the range of.
