Technical Field

[0001] The invention relates to the technical field of graphene production, and in particular to a graphene dispersing device for preparing a graphene EVA composite material. Background Art

[0002] Graphene is a two-dimensional material, and its excellent physical structural properties make it have great application potential in the fields of electronics, sensors and optoelectronic devices. Since graphene itself has a strong interaction force, it is very easy to agglomerate, and it is necessary to use a dispersing device in combination with a dispersant to disperse it in a dispersion medium. A Chinese patent discloses a graphene dispersing device (authorization announcement number CN207533129U). The patent technology discloses a graphene dispersing device, including a dispersing barrel and a stirring mechanism. A dispersing chamber is provided in the dispersing barrel. The stirring mechanism includes a motor and a stirring rod. The bottom end of the stirring rod extends into the dispersing chamber.

[0071] According to the above embodiments, the working principle of the present invention is:

[0072] When preparing the graphene EVA composite material, the graphene can be transferred to the inner side of the graphene grinding structure 3 through the graphene overflow prevention feeding structure 4, and then transferred to the inside of the graphene dispersion and mixing structure 2 after being ground by the graphene grinding structure 3. While the graphene is dispersed by wind through the graphene dispersion and mixing structure 2, the finer graphene is classified and transferred, and the heavier graphene can be reciprocatedly transferred to the graphene overflow prevention feeding structure 4 for reciprocating feeding and grinding processing;

[0073] The graphene overflow prevention feeding structure 4 is used for graphene feeding;

[0074] The graphene is transferred to the inside of the feeding transmission pipe 401 through the feed hopper 402, and the servo motor 5 403 and the exhaust fan 404 are started;

[0075] After the exhaust fan 404 is started, the air inside the feed hopper 402 and the feed transmission pipe 401 connected thereto is extracted through the exhaust holes 408 opened in the feed transmission pipe 401 and its transmission auger 407, and discharged to the outside of the feed transmission pipe 401 through the exhaust fan 404, and the graphene overflowing in the air of the feed hopper 402 is sucked into the inside of the feed transmission pipe 401 by wind, which may be lifted up and float in the air when the graphene is being fed, causing environmental pollution, and workers who accidentally enter the work area and inhale the air may suffer physical damage;

[0076] When the exhaust fan 404 discharges air, the graphene is blocked by the air filter 405 and falls into the connected dispersion cylinder 202;

[0077] After the servo motor 403 is started, the servo motor 403 drives the transmission auger 407 to rotate inside the feeding transmission tube 401, so that the graphene inside the feeding transmission tube 401 can be transmitted close to one end of the top grinding outer shaft cylinder 302, and the silicone scraper 409 rotating with the rotation rod 406 can rotate along the air filter 405 to scrape off the graphene adsorbed by the wind;

[0078] The graphene that falls into the grinding top bucket block 303 along the top grinding outer shaft cylinder 302 will fall between the grinding top bucket block 303 and the grinding bottom cone block 313. The graphene can be ground into powder by driving the grinding top bucket block 303 and the grinding bottom cone block 313.

[0079] When the grinding top bucket block 303 and the grinding bottom cone block 313 are driven to rotate, the servo motor 4 314 is started, and the servo motor 4 314 is started to drive the transmission rod 2 309 to rotate, and the transmission rod 2 309 drives the spur gear 1 305 to rotate. After the spur gear 1 305 rotates, the spur gear 2 308 is meshed and rotated, so that the transmission rod 2 309 and the transmission rod 1 306 rotate in opposite directions, and the bevel gear 2 311 can be rotated, and the rotating bevel gear 2 311 meshes with the bevel gear ring 2 310 to rotate, and the bevel gear ring 2 310 can drive the bottom grinding outer shaft cylinder 312 to rotate, so that the bottom grinding outer shaft cylinder 312 drives the inner grinding bottom cone block 313 to rotate;

[0080] The bevel gear 1 307 rotates with the transmission rod 1 306, and the bevel gear 1 307 meshes with the bevel gear ring 1 304, so that the bevel gear ring 1 304 drives the top grinding outer shaft cylinder 302 to rotate, and the top grinding outer shaft cylinder 302 drives the grinding top bucket block 303 to rotate, so that the grinding top bucket block 303 and the grinding bottom cone block 313 that rotate in the opposite direction perform a grinding process on the graphene;

[0081] The ground graphene falls directly into the dispersion outer box 201 connected to the dispersion cylinder 202, and after starting the No. 1 servo motor 227, the No. 1 servo motor 227 starts to drive the wind-driven internal rotating frame 207 to rotate inside the dispersion outer box 201, and is blocked by the wind disk net on the inner edge of the classification slot of the wind-driven internal rotating frame 207, so that the wind disk net on the classification slot blocks the graphene, so that the graphene is directly discharged into the wind-driven dispersion box 206 along the discharge pipe 205;

[0082] After starting the air supply fan 209 and adjusting the wind strength of the air supply fan 209, the graphene discharged into the wind dispersion box 206 is discharged into the classification slot of the wind internal rotating frame 207, and the graphene dispersed and blown by the wind is blocked by the wind disc net and stays in the classification slot, while the rotating wind internal rotating frame 207 rotates and moves the classification slot to above the dispersion receiving bucket 216, and the graphene remaining in the classification slot of the wind internal rotating frame 207 lacks the wind force to be blown and can fall into the dispersion bottom box 217 connected to the dispersion receiving bucket 216;

[0083] The graphene falling into the dispersion bottom box 217 can be rotated by starting the servo motor 3 226. The rotating servo motor 3 226 drives the mixing frame 222 on the mixing rod 221 to rotate inside the dispersion bottom box 217, and the graphene remaining on the filter screen 218 is dispersed and mixed. The graphene passing through the filter screen 218 is dispersed and meets the standards. The qualified graphene will be discharged through the discharge pipe 220.

[0084] The graphene remaining on the filter screen 218 is discharged into the transverse transmission pipe 208 through the circulation pipe 219;

[0085] When the graphene inside the dispersion bottom box 217 is mixed and processed, the ultrasonic vibration module 225 and the vibration motor 224 can be started, and the ultrasonic vibration module 225 transmits the vibration force to the filter screen 218 through the mixing frame 222 to perform ultrasonic vibration dispersion processing on the graphene;

[0086] When the vibration motor 224 is started, a physical vibration force is generated, and the graphene can be subjected to physical vibration dispersion processing by the vibration motor 224;

[0087] The graphene remaining on the filter screen 218 can be discharged into the circulation pipe 219 through the rotating mixing frame 222, and the unqualified graphene is transmitted to the inside of the horizontal transmission pipe 208 through the circulation pipe 219, and the servo motor 1 211 is started, and the horizontal auger 210 is driven to rotate by the servo motor 1 211, and the graphene falling into it is transmitted to the inside of the vertical transmission pipe 212 by the rotating horizontal auger 210, and then the vertical auger 213 is rotated by the started servo motor 214, and the graphene discharged into the inside of the vertical transmission pipe 212 is discharged into the inside of the feed hopper 402 through the vertical discharge inclined material pipe 215, and the unqualified graphene is re-grinded and processed;

[0088] The dispersed processing frame 1 can be rotated by the hand lever on the load-bearing adjustment bolt 7, so that the load-bearing adjustment bolt 7 moves along the support frame 5 in a spiral height, so that the support adjustment pad 8 contacts the ground, supports the device and can adjust the horizontal height;

[0089] The dispersed processing frame 1 can be moved on the ground via the self-locking universal wheels 9 .
