Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
See Fig. 1 to Fig. 4, a kind of turbulent flow roller, comprise roller core 1, described roller core 1 is hollow roller core or solid roller core, roller core 1 is outer is removably arranged with some annular friction sheets 3, described annular friction sheet 3 is set in outside roller core 1 equably, distance often between adjacent two annular friction sheets 3 is 10 ~ 30mm, the thickness of each annular friction sheet 3 is 1 ~ 3mm, often between adjacent two annular friction sheets 3, spacer sleeve 2 is all removably installed, described roller core 1, annular friction sheet 3 and spacer sleeve 2 are coaxially arranged, two surfaces of annular friction sheet 3 are all evenly distributed with some raised lines 4, the shape of cross section of raised line 4 is triangle, and leg-of-mutton any limit is less than 4mm, raised line 4 annularly friction plate 3 arranges radially, and raised line 4 mutual dislocation on relative two faces of adjacent two annular friction sheets 3 is arranged.
Below implementation process of the present invention is described in further detail:
The present invention comprises a roller core 1, roller core 1 is hollow roller core or solid roller core, multiple annular friction sheet 3 is had at roller core 1 overcoat, spacer sleeve 2 is provided with between annular friction sheet, spacer sleeve 2 and roller core 1, annular friction sheet 3 are coaxial, by non-solder as screw thread is stepped up at two ends, or the conventional method such as key connection makes spacer sleeve 2, annular friction sheet 3 interfixes, without relative motion with roller core 1.The present invention is laterally arranged in the slurry in head box casing, configures corresponding bearing arrangement and transmission device.Slurry is from when flowing through between annular friction sheet 3, and along with rotary motion of the present invention, due to the existence of speed difference, annular friction sheet 3 pairs of slurries can produce friction and shear action, thus in slurry stream turbulization.
Because two surfaces of annular friction sheet 3 are provided with raised line 4, turbulence intensity can be improved, flow because slurry is parallel to annular friction sheet 3, compared with doctor-roll, larger lateral flow can not be produced, when using dilution water to regulate page quantitative difference of banner, the scope of the dilution water horizontal proliferation added of fixing a point would not be excessive, thus realize precisely regulating.
The shape of cross section of raised line 4 affects intensity and the uniformity of turbulent flow, the cross section of raised line 4 is designed to triangle and is conducive to the microturbulence of annular friction sheet 3 near surface to transmit more farther, so that it is more even to make turbulent flow distribute.Annular friction sheet 3 in the present invention and spacer sleeve 2 can also adopt adhesive to make, to keep clean surface better.
The mutual alignment relation of raised line 4 not only affects being uniformly distributed of turbulent flow, but also affects flow direction.Raised line 4 mutual alignment on adjacent two annular friction sheet 3 surfaces is set to intervening portion by the present invention, instead of just to or symmetric position, turbulent flow not only can be made to transmit more farther, turbulent flow is distributed more even, the more important thing is the flow effect that can produce and swing, make more fiber transversely arranged, thus improve the defect that in existing page, fiber longitudinal arrangement is more, make page indulge lateral performance more consistent, generally state with vertical lateral pull extent.
It is to starch the needs producing high-strength microturbulence in stream that any length of side of the cross-sectional triangle of raised line 4 is less than 4 millimeters.The size impact of raised line 4 size of turbulent flow, and research shows, in fibrous suspension, the ideal dimensions of high-strength microturbulence should below 4 millimeters.
Additionally by change rotary speed of the present invention, turbulence intensity can be changed, to adapt to the needs of different material and product.The present invention overcomes many drawbacks that existing doctor-roll head box turbulent flow is oversize, turbulence intensity skewness, lateral flow large, starch stream instability, effectively can not use the quantitative difference of banner of dilution water adjustment page.But also can increase the transversely arranged of fiber in page, thus it is poor to reduce vertical lateral pull.
