The working principle of the application is as follows: before the nano material is grinded, the nano material flows into the grinding mechanism 3 through the heating block 7, a feeding pipe 8 is arranged on the side surface of the heating block 7, and the feeding pipe 8 can heat the heating block 7, so that the temperature is not too low before the nano material enters the grinding mechanism 3, the fluidity of the nano material is increased, and the nano material is convenient to flow in the grinding mechanism 3;
when the nano materials are grinded, the servo motor 4 is started at the moment, the grinding shaft 302 is driven to rotate by the connecting shaft 301 when the servo motor 4 is started, the grinding shaft 302 rotates to drive the grinding blades 303 to rotate, so that the nano materials in the grinding cylinder 304 are grinded, the grinded nano materials enter the dispersing cylinder 508 through the connecting pipe 11, the connecting shaft 301 drives the first bevel gear 501 to rotate when rotating, the first bevel gear 501 drives the rotating shaft 503 to rotate by the second bevel gear 502 when rotating, the driven shaft 507 is driven to rotate after being driven by the lower synchronizing wheel 504, the synchronous belt 505 and the upper synchronizing wheel 506, the stirring blades 509 are driven to rotate when the driven shaft 507 rotates, the nano materials entering the dispersing cylinder 508 are filtered by the stirring blades 509 and are discharged by the discharging pipe 6, and the nano materials which do not meet the requirements flow into the grinding mechanism 3 again through the return pipe 10 to grind;
when the nano material is ground in the grinding mechanism 3, at this time, when the temperature in the grinding mechanism 3 is higher, the water pump 201 can start to pump the water in the cooling water tank 9 into the cooling water pipe 202, when the cooling water pipe 202 is filled with water, the temperature of the cooling cylinder 203 can be reduced, and the grinding mechanism 3 is contacted with the cooling cylinder 203, so that the cooling cylinder 203 is cooled, and the grinding temperature in the grinding mechanism 3 is ensured to be stable.
Finally: the foregoing is only illustrative of the preferred embodiments of the present application and is not to be construed as limiting the application, but rather as various modifications, equivalent arrangements, improvements, etc., within the spirit and principles of the present application.
