The specific embodiment

To shown in Figure 4, a kind of novel high density waterpower is decomposed fiberizer, mainly is made up of cell body 1, screen plate 3, impeller 2, motor 4 and gearbox 6 like Fig. 1.

Said cell body 1 is the cylinder hollow body; Open upper end, lower end closed, this cell body 1 is mounted on the support 5; The upper end oral area of cell body 1 also offers stock inlet 13; The lower end closed place of cell body 1 offers slag-drip opening 12, and cell body 1 inner chamber upper side wall is provided with several drainage plates 8, and said this drainage plate 8 is oblique triangle.

Screen plate 3 is welded on cell body 1 inner chamber downside position, and forms an enclosed cavity 1a with cell body 1, also is provided with grout outlet 11 on this enclosed cavity 1a, and said grout outlet 11 is through enclosed cavity 1a and extend to cell body 1 outside; Screen plate 3 is funnel-form, is made up of inside and outside double-layer structure, and forms pulp road, a space 33 between this internal layer 31 and outer 32, and inside and outside layer also offers several through holes 34 on (31,32) surface.

Rotary main shaft 7 is connected with gearbox 6 through connector 9; Gearbox 6 links to each other with motor 4 through belt; One end of rotary main shaft 7 is made as bullet; Extend through cell body 1 bottom central and to cell body 1 inner chamber middle part the bullet end of this rotary main shaft 7, on the end of these rotary main shaft 7 bullets impeller 2 is installed also, and through left-hand thread tooth screw 10 impeller 2 is locked on the end of rotary main shaft 7 bullets.
