Detailed Description
The following detailed description is provided to further explain the technical features and advantages of the present invention by referring to the accompanying drawings in combination with the embodiments.
As shown in fig. 1-4, the utility model relates to a device for grinding and dispersing nano-scale materials,

The utility model discloses the structural feature of device does:
1. the first grinding rotor is in a long cylindrical shape, is fixed on the main shaft through a mounting hole, is in a hollow structure, and can accommodate components such as a separator and the like inside;
2. six long-strip-shaped inclined long holes are uniformly distributed on the periphery of a cylinder of the first grinding rotor, the inclined long holes and a main axis (the pressure direction of a pump) are inclined by 15-20 degrees and are spirally arranged, when the first grinding rotor rotates, a component force opposite to the pressure direction is generated on an inclined plane opposite to the pressure direction, the grinding medium is forced to reversely flow by the counter force, and the problem that the grinding medium is distributed at a discharge end under the action of the pressure of the pump is solved;
3. the reinforced bar nails are uniformly distributed on the outer side of the cylinder of the first grinding rotor, are uniformly distributed along with the inclined long holes, and have counter force to force the grinding medium to reversely flow. Meanwhile, a spiral structure system consisting of the rod nails, the rod nail intervals, the inclined long holes and the like can generate relatively complex vortex and turbulence phenomena when moving at a high speed, so that the grinding media generate irregular acceleration or deceleration to drive more grinding media to move irregularly, the collision speed of the grinding media is generally increased, and the grinding efficiency is improved;
4. four elliptical through holes are uniformly distributed in the inner portion, close to the left side, of the cylinder of the first grinding rotor, and the effect of the four elliptical through holes is mainly to increase the flowing space of grinding media and slurry in the cavity, form a plurality of complete cycles or incomplete half cycles, break through the motion law of the grinding media as much as possible, drive more media to move and improve the grinding efficiency.
The structure of the traditional grinding device is shown in fig. 4, parts such as a machine seal 5, an inner cylinder, an outer cylinder and a separator are fixed, when the grinding device works, a second grinding rotor 11 rotates at a high speed along with a main shaft to drive a grinding medium 4 in a cavity to do rotary motion, the material 3 is crushed in modes such as collision, shearing and extrusion, and then the material with small particle size is discharged through a gap of the separator. In whole working process, the material is constantly pumped into the cavity and is dispersed and ground under the pressure of pump, and the material also constantly discharges from the separator simultaneously, because the grinding medium diameter is greater than the separator clearance, in the cavity can be stayed always to the grinding medium, under the continuous pressure effect, the feeding side will be kept away from to the grinding medium, to the discharge end gathering, will form at the discharge end at the result and cross the mill, and relevant parts wearing and tearing are rapid, and the life-span reduces. The feed side is lack of grinding media to cause under-grinding and even ineffective grinding, and practice proves that the grinding efficiency is seriously influenced by frequent ineffective grinding areas of one third, partial materials with high viscosity and even over one half of ineffective grinding areas. In addition, the existing grinding structure, especially the static discharging mode (with the advantage of convenient maintenance, cleaning and replacement) fixed by the separator shown in fig. 4, is generally made relatively simple, which can improve the discharging efficiency, and on the other hand, the disadvantage is also obvious, namely the grinding efficiency is reduced, for example, the wall thickness of the grinding structure is very thin, the kinetic energy is insufficient during rotation, and it is difficult to drive more grinding media to move sufficiently, which affects the dispersive grinding efficiency.
