However, the renewable green energy sources have intermittent and unstable characteristics, and how to efficiently convert and store the unstable and intermittent green energy sources becomes a key problem for effectively utilizing the green energy sources, which puts higher requirements on the energy storage capacity of the electric energy storage. At present, the electric energy storage mainly comprises: batteries (lithium batteries and fuel cells), electrochemical capacitors, and dielectric capacitors. The battery is only suitable for being used as continuous and stable power output equipment due to low power density. The electrochemical capacitor has short cycle and potential safety hazard. The dielectric capacitor has the advantages of high charge-discharge rate (< 1 [ mu ] s), high power density (108W/kg) and long cycle life (5 ten thousand times), and has wide application prospects in the fields of nuclear physics and technology, new energy power generation, medical operation laser, hybrid electric vehicles, petroleum and gas exploration, smart grids, directional energy weapons, high-energy pulse power supplies and the like. However, the energy storage density of the dielectric capacitor is relatively low, which makes the dielectric capacitor need a larger volume to realize the storage of energy in energy system applications, for example, the energy storage capacitor applied to a hybrid electric vehicle accounts for about 40% of the volume of the whole inverter device, so to expand the application field and realize the miniaturization and light weight of the related application device, the energy storage density and the energy storage efficiency of the dielectric capacitor must be improved as soon as possible.

2. After the grinding material is ground, some grinding material will adhere to the wall of the tank, and the grinding efficiency of the grinding material will be relatively low.
3. After the grinding is accomplished, it is inconvenient when wasing the inner wall and the diapire of polyurethane ball-milling jar, and it is inconvenient when grinding the material ejection of compact, for example the patent that discloses in patent No. 2015201974415, it establishes a mesh screen in the inner tube for the convenience ejection of compact, and divide into the inner chamber of inner tube and grind chamber and ejection of compact chamber, but the ball is when grinding, and the ball has certain weight, when colliding with the mesh screen, can drop the cuttings of mesh screen material, thereby mix in the grinding material, make the grinding material precision impure.
On the basis of the above, the present invention provides a new device to solve the above problem.
