Description
Technical field
The utility model relates to a kind of rotor of the pulper for fibrous material Preparation equipment, described rotor arrangements in container for being included in the circulation of fibrous material suspension in this container, and the compass screen surface of the inswept container of described rotor, its rotor is formed by rotor head, has fixed multiple rotor blades on described rotor head in periphery.
Background technology
This type of pulper is mainly used in dry paper pulp material or old paper to be incorporated in suspension.Pulper consists essentially of for the container of suspension and at least one rotor.The material of sending into mixes with water strongly with the ball of large piece, band or compacting, wherein produces hydraulic substance circulation by rotor.Will be understood that this equipment optimization, wherein substantially make every effort to quick and economic pulping.In many cases, rotor is put near the wire screen of plane, and described rotor keeps sieve not blocked.By opening of sieve, the material being broken is taken out as suspension.
As the type for pulper, implement the hydrostatic column standing vertically with rotor at bottom section.In this container from above add water and material to be broken, and in suspension, produce vortex flow by means of rotor, wherein therefore at interior zone internal rotor, material is pulled down and radially outward presses in bottom section, produced and circulated with this.Also become known for controlling the mobile measure that this circulates.Therefore, for example, for example, will circulate braking by the corresponding flow device (, baffle plate or flow disruption device) on chamber wall, only little for the contribution that pulping rose because of it.
But the effect at this rotor may be not yet completely satisfied.
Summary of the invention
Therefore technical problem to be solved in the utility model is to improve the efficiency of rotor.
According to the utility model, this technical problem solves by the different height that rotor blade is had from compass screen surface.Flat rotor blade is responsible for sieving the strong shearing in region and is made to sieve unobstructed, high rotor blade and strengthened and circulated.
At this, prove effectively on rotor head, to fix especially multiple high and multiple low rotor blades, and preferably in direction of rotation, made low rotor blade follow high rotor blade.In addition, tool is advantageous is on rotor head, to fix six rotor blades.
Rotor head has relatively large diameter.Although efficient on less rotor head energy, the easily material plate that be not broken of forming position on rotor head and on the interior zone of rotor blade.Therefore, affected significantly the work of rotor.Paper pulp plate even may cause the termination of circulation in container.
Large rotor head causes the large distance in the region of rotor head between rotor blade, makes large ball fragment have many positions and does not disturb flowing in rotor.
In addition, advantageously the side of the sensing direction of rotation of multiple, preferred all rotor blades tilts in direction of rotation from compass screen surface.And the large gap between rotor blade combines, the high efficiency that this is responsible for the good compactedness of impeller clearance and is therefore responsible for rotor.
This still can improve by the upper limb that high rotor blade is had stretch in direction of rotation.Also improved the conveying of rotor and reduced air sensitivity with this.
Also can flow and form by the arcuate shape support of rotor blade.
Comprehensive experiment shows, advantageous at this tool is to make the side of sensing direction of rotation of rotor blade and the periphery of rotor head become the angle between 30 ° to 50 °, preferably become the angle between 35 ° to 45 °, and/or make rotor blade sensing direction of rotation side with become the angle between 30 ° to 50 ° by the inswept rotor circle of rotor blade, preferably become the angle between 35 ° to 45 °.
At this, particularly advantageously make for the efficiency of rotor the side of sensing direction of rotation of rotor blade and the periphery angulation of rotor head and with mutually differed respectively maximum 10 ° by the inswept rotor circle angulation of rotor blade, preferably differ maximum 5 °.
For producing uneven in the situation that paper pulp piece is larger and therefore being thrown away, at least one attached leaf should be installed on rotor head, described attached leaf preferably extends and arranges asymmetrically about rotor blade in the periphery of rotor head.
Advantageously, rotor uses in paper pulp pulping.
Brief description of the drawings
Explain in detail the utility model according to embodiment hereinafter.Each figure is:
Fig. 1 shows the schematic cross-section by pulper;
Fig. 2 shows the top view of rotor 1; With
Fig. 3 shows total view of rotor 1.
Detailed description of the invention
The form of implementation that the utility model can be applicable to the pulper on it is the pulper open according to the columniform top of the setting of Fig. 1, and wherein sieve and rotor 1 are in bottom section.
Be in operation, paper pulp and water are fed in the container 2 of pulper.The pumpable fiber suspension 3 of making takes out as good slurry by the sieve opening of the compass screen surface 4 of sieve.
Even when this rotor 1 horizontal positioned and during therefore always with the operation of vertical axis always not in pulper, this also from then on specific installation situation set out and correspondingly adopt the form of presentation of " top " and " below ".Rotor 1 is connected and in direction of rotation 8, is driven rotatably in the time that pulper moves with the rotor blade 6,7 of six arcs altogether.
Make in known manner rotor 1 cooperate with compass screen surface 4.The downside that corresponding sieve is positioned at rotor 1 has alap distance.This low distance is advantageously several millimeters, and causes the keeping clear of sieve opening of good pulping and compass screen surface 4.At this, sieve can also provide bar in the side towards rotor 1, and this has strengthened pulping effect.In this case, the distance of the upside of rotor 1 and bar is crucial.
In Fig. 2 and Fig. 3, detailed illustrated rotor 1 is suitable for the fiber suspension with the high concentration in 2% to 6% scope especially.
For this reason, rotor 1 has the relatively large rotor head 5 with diameter 10, has fixed six rotor blades 6,7 in the periphery 15 of rotor head 5.Can effectively tackle the formation of the paper pulp plate not being broken by large rotor head 5.Rotor blade 6,7 has the different height while observing perpendicular to compass screen surface 4 at this, and wherein, in direction of rotation 8, low rotor blade 6 is followed high rotor blade 7.
Flat rotor blade 6 is responsible for keeping clear of strong shearing and compass screen surface 4, and high rotor blade 7 is crucial for circulation.
For supporting the conveying of rotor 1, the side 11 of the sensing direction of rotation 8 of all rotor blades 6,7 tilts in direction of rotation 8 from compass screen surface 4, and this has produced towards the components of flow of compass screen surface 4.For promoting pulping, high rotor blade 7 has the upper limb 12 stretching in direction of rotation 8.
In addition, being proved to be useful is as illustrated in this, and the side 11 of the sensing direction of rotation 8 of rotor blade 6,7 is with the periphery 15 of rotor head 5 and and formed respectively by the inswept rotor circle 13 of rotor blade 6,7 angle between 35 ° to 45 ° 14,16 that approximate size is identical.
In addition, have attached leaf 9 on rotor head 5, described attached leaf 9 is asymmetricly arranged in the interior extension of periphery 15 of rotor head 5 and with rotor blade 6,7.
For point between the side 11 of direction of rotation 8 and the periphery 15 of rotor head 5 and and rotor justify the angle 14,16 forming between 13, always use tangent line at this.
