Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, detailed description of the invention of the present utility model is described in further detail.
By reference to the accompanying drawings 1, shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, illustrate the structure of a kind of circular-gap nanometer sand mill of the present utility model, this sand mill comprises frame 101, and is arranged on sand cylinder 4 and motor 100 in frame 101, specifically as shown in Figure 1.
As shown in Figure 2, a side of described sand cylinder 4 is fixed with material flange 2, and opposite side is fixed with end cap 7; 4 li of sand cylinders also comprise a main shaft 1, and described main shaft 1 puts in sand cylinder 4 from material flange 2 ends, and described main shaft 1 is connected with motor 100 by belt; In the cylindrical shell of described sand cylinder 4, also comprise sleeve rotor 12, sleeve rotor 12 is fixed on main shaft 1; On described material flange 2, be also provided with charging aperture 3, discharging opening 13, sand cylinder 4 contains cooling jacket layer, and is provided with cooling water inlet 10 and coolant outlet 5, has the pearl of adding mouth 8 and put pearl mouth 9 on end cap 7.
As shown in Figure 3, the outer wall of described sleeve rotor 12 is provided with multiple protruding 52, and the protruding 52 center on hand of helix is together in series and on the face of cylinder of sleeve rotor, forms many helixes.Preferred version: be fixed with separator 11 in the hollow area in described sleeve rotor 12.In the end of described main shaft 1, be provided with blind hole 14, described blind hole is communicated with described separator 11.The bottom of described blind hole is provided with radial hole 15, and radial hole 15 is connected with the discharging opening 13 of material flange, forms the exit passageway of material.The inwall of the outer wall of described sleeve rotor 12 and described sand cylinder 4, at a distance of 6 ~ 15mm, forms the cyclic formula slype 6 in a high-energy-density space.
As shown in Figure 4, on the face of cylinder of described sleeve rotor 12 outer walls, be provided with bulge-structure, these projections 52 are horizontally disposed with vertically on the face of cylinder, on the face of cylinder, do not arrange on protruding axial direction and just correspondingly formed horizontal groove 32,32 li of horizontal grooves are provided with through hole, be that horizontal bore 53(horizontal bore 53 is axially parallel with sleeve rotor), horizontal bore 53 is communicated with separator 11.
