Description
Technical field
The utility model relates to papermaking equipment and makes the field, exactly be a kind of be used for paper pulp coarse sizing and purification revolve the scalping of drum-type pressure.
Background technology
At present, the pressure pulp screen of pulping and paper-making industry mainly is divided into outer-flowing type and in-flow two big classes, basic structure all is that screen cylinder is fixed, rotor rotates, by rotor input power slurry is screened, be used for the less slurry fine screen choosing of impurity content, this design has many advantages.But when being used for the more secondary stock coarse sizing of impurity content, there are many shortcomings: the one, slurry directly enters between screen cylinder and the rotary blade, rotary blade directly acts on the slurry that contains a large amount of impurity, causes the heavy wear of screen cylinder and rotary blade, and descend service life greatly.The 2nd, rotary blade causes impurity to produce fragmentation to the direct effect of impurity, and impurity appearance and size diminishes, and quantity increases, and removes decrease in efficiency.The 3rd, impurity content more easily twines rotary blade, and stops up screen cylinder, causes living load to increase unusually, causes screen cylinder and rotary blade to damage when serious.
The content of utility model:
The purpose of this utility model is:
Develop a kind of drum-type pressure scalping of revolving, the coarse sizing that is used for the more secondary stock of impurity content, can reduce the wearing and tearing of impurity to screen cylinder, can make rotary blade not directly act on impurity again, avoid the fragmentation of impurity, winding and the damage phenomenon of impurity to rotary blade can not take place yet, improve screening effeciency, reduce power consumption, prolong the service life of screen cylinder and rotary blade.
The purpose of this utility model is achieved in that and is provided with fixing rotor assembly in cylindrical shell, the rotor assembly is fixed by bolts on the shell of bearing body assembly, screen cylinder supports sealing flange by screen cylinder and is connected with transmission device in the bearing body assembly, be provided with the moving ring flange of screen cylinder in the bottom of screen cylinder, on the perimeter wall of the moving ring flange of screen cylinder, be provided with and dial pulpboard, bottom at the moving ring flange of screen cylinder is provided with group paddle sheet, on the perimeter wall of screen cylinder, also be provided with the oblique ripple of constant slope, ditch bottom at each oblique ripple also is provided with the sieve aperture that is evenly distributed, on the perimeter wall of rotor assembly, be provided with the connected rotary blade of bolt, cylinder inboard wall is provided with baffle, and heavy slag scum pipe is whole to be protruded on the outer wall of cylindrical shell.
By above setting, the utility model reasonable in design purifies the screening effeciency height, screen cylinder and rotary blade long service life, and power consumption is low.

Specify embodiment
As shown in FIG., the utility model mainly is made up of cylindrical shell 1, stock inlet 2, grout outlet 3, heavy slag scum pipe 4, light slag scum pipe 5, screen cylinder 6, rotor assembly 7 etc.In cylindrical shell 1, be provided with fixing rotor assembly 7, rotor assembly 7 is fixed by bolts on the shell of bearing body assembly 8, screen cylinder 6 supports sealing flange 19 by screen cylinder and is connected with transmission device in the bearing body assembly 8, be provided with the moving ring flange 9 of screen cylinder in the bottom of screen cylinder 6, on the perimeter wall of the moving ring flange 9 of screen cylinder, be provided with and dial pulpboard 10, bottom at the moving ring flange 9 of screen cylinder is provided with group paddle sheet 13, on the perimeter wall of screen cylinder 6, also be provided with the oblique ripple 14 of constant slope, also be provided with the sieve aperture 17 that is evenly distributed in the ditch bottom of each oblique ripple, on the perimeter wall of rotor assembly 7, be provided with the connected rotary blade 18 of bolt, cylindrical shell 1 inwall is provided with baffle 12, heavy slag scum pipe 4 whole protrusions on the outer wall of cylindrical shell 1.
Power is imported into by driving pulley 11, and drives screen cylinder 6 rotations; Rotary blade 18 is fixed, and screen cylinder 6 rotates; Screen cylinder 6 Surface Machining have oblique ripple 14, and ripple high 15 is 2～3mm, and oblique ripple inclination angle 16 is 12～25 °, and screen cylinder 6 bottoms have ring flange 9 to rotate with screen cylinder 6 with bolting.
Operation principle is:
The slurry that contains impurity enters cylindrical shell 1 by stock inlet 2 tangential directions, under centrifugal action, heavy seeds is thrown toward cylindrical shell 1 inwall, and enter the heavy seeds scum pipe 4 of outside protrusion rapidly, make heavy seeds before not contacting screen cylinder 6, promptly from slurry, separate, avoided the wearing and tearing of heavy seeds screen cylinder 6; Slurry produces turbulence under the effect of the baffle 12 on cylindrical shell 1 inwall; Driving pulley 11 is given bearing body assembly 8 with transmission of power, bearing body assembly 8 upper end spindle noses connect screen cylinder and support sealing flange 19, and drive screen cylinder 6 rotations, in screen cylinder 6 rotary courses, 14 pairs of slurries of the oblique ripple on surface produce agitaion, make slurry form microturbulent motion at sieve aperture 17 places, stop slurry to form network-like floc sedimentation at sieve aperture 17 places, reduced the resistance of good slurry, thereby improved screening effeciency and output by sieve aperture 17; Fixing rotary blade 18 constantly produces the effect of negative pressure-pumping effect and cleaning screen cylinder 6 in screen cylinder 6 rotation processes, will very starch to be drawn in the screen cylinder 6, and discharge continuously from grout outlet 3, rotary blade 18 moves in good slurry environment all the time, has alleviated wearing and tearing greatly, has improved service life; Light impurity and size rise to light impurity scum pipe 5 greater than the not size degradation scraps of paper of sieve aperture 17 and discharge continuously.
Revolving the scalping of drum-type pressure when normally moving, there is pressure differential in screen cylinder 6 inside and outside slurries, and slurry is under the effect of power such as pressure differential, and good slurry enters the inboard by the outside; Moving ring flange 9 is fixed by bolts to the bottom of screen cylinder 6, rotate with screen cylinder 6, group paddle sheet of fixing on its circumference 13 of dialling pulpboard 10 and the welding of bottom downward direction, the thick slurry without crossing sieve aperture 17 that moves between moving ring flange 9 and quiet ring flange 20 is under pressure thrown away continuously, make pressure inside between ring flange 9 and the quiet ring flange 20 and outside centrifugal force reach balance, both prevented that impurity from twining and stopping up the screen cylinder bottom, will very starch the district again and under dynamically, separate with thick slurry district.
The utlity model has reasonable in design, purification screening effeciency height, screen cylinder 6 and rotary blade 18 long service life, advantages such as power consumption is low, in the waste paper pulp-making technological process, use alternative traditional high concentration desanding device, pressure scalping, and can reduce the configuration power of defibrator significantly, realize energy-saving and cost-reducing.
