Abstract
The utility model relates to a helical blade rotor of a hydrapulpter, comprising a wastepaper crushing part, a pulp conveying part and a rotor core part. More than two groups of blades are fixedly arranged on the rotor core, and each group of the blades is composed of a plurality of segment of discontinuous blades. Each segment of blades folds an angle towards the direction of pulp flow, the pulp is subjected to shunting action, and an integrity swirl circulation and a local swirl circulation are formed in a slot body. The disconnected point of each section of blades is provided with a cutting edge, and the wastepaper is continuously torn and mutually rubbed under the function of the swirl circulation and the cutting edge and dissociated into single fiber to form pulp suspension. The helical blade rotor is suitable for tearing various wastepaper, comprising wet-strength paper and plastic compound paper.
Description
The utility model belongs to the pulp and paper industry machinery technical field.
Waste paper after reclaiming and clear water are added in the pulper cell body, and waste paper is done the vortex circulation with current under the effect of pulp kneader rotor, in this process, waste paper is torn, broken, be dissociated into the single fiber bundle, make pulp suspension, thereby saved the papermaking raw material.The hydrabrusher of at present existing multiple pattern can achieve the above object.
In order to improve the operating efficiency of hydrabrusher, make it to adapt to the high dense size degradation of multiple waste paper.No. 4460132 patents of the U.S. have proposed the hydrabrusher of discontinuous helical blade rotor.Its rotor core part top is cylindrical, and the bottom is a circular cone, is non-streamline, is fixed in the discontinuous blade of plurality of sections on the rotor core, and its structure and distribution do not make slurry stream be subjected to shunting action, and relatively poor to tearing of waste paper and crushing effect, power consumption is big.
The purpose of this utility model is to provide a kind of can comprise various waste paper such as wet strength paper and extrusion coating paper by size degradation; Crushing effect is good; The discontinuous helical blade rotor of the high density hydraulic pulper of high efficiency.
The utility model is according to the flow behavior of slurry stream, adopt the discontinuous helical blade rotor structure of plurality of sections, be connected with two groups with blade in rotor core, every group of blade is made up of the discontinuous blade of plurality of sections again, every section blade is to the slurry flow path direction angle of turning back, stud with carbide alloy such as blade or built-up welding tungsten carbide in the gap of the every section blade direction relative with slurry stream and form the edge of a knife, this edge of a knife is very favourable to tearing the broken scraps of paper.During the rotor rotation, slurry stream is subjected to shunting action at the angle place that turns back of every section blade, and whole vortex circulation of formation and the circulation of local vortex in the pulper cell body, waste paper is friction mutually in this vortex and cyclic process, and under the effect of the edge of a knife, be torn into broken small paper block, and then fragmentation is dissociated into single fiber, form pulp suspension, external by the stock pump drain tank again.According to experiment, the angle that every section blade is turned back to the slurry flow path direction on the rotor is generally 10 °～30 °.
Compared with the prior art advantage of the present utility model is:
1. every section of rotor blade makes slurry stream be subjected to shunting action to the slurry flow path direction angle of turning back, and can aggravate to starch the vortex circulation of stream, shortens the size degradation time.
2. the gap of every section blade of the direction relative with slurry stream studs with carbide alloy such as blade or built-up welding tungsten carbide, forms the edge of a knife, and this edge of a knife helps the fragmentation of tearing of the scraps of paper, has improved size degradation efficient.
3. the rotor core bottom is streamlined, helps the conveying and the circulation of slurry.
Below in conjunction with accompanying drawing the utility model is described further:
Blade construction of the present utility model can have three kinds of formation, and as shown in the figure: Fig. 1 and Fig. 2 are first embodiment; Fig. 1 and Fig. 3 are second embodiment; Fig. 1 and Fig. 4 are the 3rd embodiment.Fig. 1 is a front view; Fig. 2, Fig. 3, Fig. 4 are respectively the blade section structure charts of first, second, third embodiment.
The helical blade rotor mainly is grouped into by slurry transport portion, waste paper broken segment and rotor core.The slurry transport portion is made up of uniform three groups of blades that are welded on the rotor core (1), and every group of blade is made up of three sections discontinuous helical blades (2); The gap of every section blade (6) one side of slurry stream relatively studs with blade (3), forms the waste paper broken segment.In first embodiment, all blades (2) two ends gaps (6) angle of not turning back; In second embodiment, every section blade (2) two ends gaps (6), blade (2) top is towards the slurry flow path direction 20 ° of angles of turning back; In the 3rd embodiment, every section blade (2) two ends gaps (6), blade (2) top is towards the slurry flow path direction 15 ° of angles of turning back, and blade (2) bottom is along the slurry flow path direction 15 ° of angles of turning back.Rotor core (1) is a cast body, and top is cylindric (1 ') for one section, and the bottom is streamlined (1 ").
After waste paper enters pulper cell body (4), be soaked in water, macerate, the scraps of paper are under the effect of current and blade (2), in cell body (4), make the strong shuttling movement of vortex, and constantly torn fragmentation by current and blade (3), form slurry stream, slurry stream flows along the hand of spiral along blade (2) upper surface from top to bottom, in second and the 3rd embodiment, slurry stream is subjected to shunting action at blade (2) knuckle place (6), makes vortex circulation aggravation, after repeatedly circulating, the scraps of paper are dissociated into single fiber, form pulp suspension.By stock pump outside (5) discharge cell body (4).
Adopt the utility model size degradation waste paper, can improve pulper size degradation efficient; Shorten the size degradation time; Reduce power consumption, the interior pulp density of cell body is reached more than 8 percent, make high concentration paper pulp.
