Joint face between described wing stationary plane and the first turbulent flow generating region is formed and meets slurry face, and the front portion meeting slurry face is set to the cambered surface of rounding off.
Joint face between described wing stationary plane and backwash effect generating region forms tail slurry face, and the rear portion in tail slurry face is set to the cambered surface of rounding off.
The beneficial effects of the utility model:
By technique scheme, can there is turbulent phenomenon in turbulent flow generating region, enables the slurry stream hole by screen cylinder or seam, and turbulent flow generating region is obvious and very brief, can form very brief positive pulse；Backwash effect generating region can produce backwash effect, and to clean screen cylinder, backwash effect generating region is relaxed and long action time, can form the back pulse of the time length of maintenance.Whale formula rotor block of the present utility model, within a burst length, forms the back pulse of the time length of very brief positive pulse, maintenance, and positive pulse is very brief effectively, it is ensured that higher screening the pulp efficiency, and the time that back pulse keeps is long, is hardly damaged screen cylinder.
Joint face between described wing stationary plane and the first turbulent flow generating region is formed and meets slurry face, the front portion meeting slurry face is set to the cambered surface of rounding off, the whale formula rotor block drag effect to slurry stream can be reduced, and when slurry stream impacts whale formula rotor block, due to the surface, slurry face of meeting of whale formula rotor block have smooth excessively, slurry stream can be pushed to upper and lower sides, it is to avoid slurry stream directly impacts whale formula rotor block, thus improving service life and the screening effect of rotor block.
Joint face between described wing stationary plane and backwash effect generating region forms tail slurry face, and the rear portion in tail slurry face is set to the cambered surface of rounding off, enough can reduce the rotor block drag effect to slurry stream.
