Angle α (seeing Figure 18) between the forward edge of radial girders and rotor blade 4 can change between 0 ° to 45 °.
Rotor blade 4, front side in rotation direction have screwed abrasion protection plate 6.These abrasion protection plates 6 are excellent
Choosing is by extremely abrasive material manufacture, and is replaced after reaching the limit of wear.As by shown Screw connector 7
As being drawn, this very simply and can be carried out by being unclamped by two bolts with saving time.
The wheel hub 3 of rotor is fixed in drive shaft 18, and this drive shaft is also referred to as armature spindle.Under drive shaft in FIG
On end, can the direct unshowned motor of Flange joint, or such as come by belt drive unit or drive mechanism
Indirectly by motor-driven.
Certainly, all motor well known in the prior art may be used for driving the drive shaft of rotor.Here, can be suitable for
So-called torque motor or traditional AC induction motor or ac synchronous motor.By the rotating speed of these motor the most also
The operating characteristic of rotor can be affected.Therefore, the rotating speed driving motor controls to be favourable in some cases.
Drive shaft 18 is rotatably disposed on bearing block 17.This bearing block 17 must be implemented certainly the most lustily, because of
It is applied on rotor for significant dynamic force during operation.Kneading trough is arranged to screw up on bearing block 17 and with it.
Kneading trough mainly includes base plate 16 and the truncated cone-shaped sidewall (not having reference) being connected to it on.The end of at
Centering ring 13 it is disposed with on the interior diameter of plate 16.Centering ring 13 1 aspect is strengthened in the region for the reach through hole of drive shaft 18

The bottom of plate 16 screws up.The screwed hole arranged for this shows in base plate 16 and does not has reference.
In base section plate 8, it is represented by reference 12.Base section plate 8 can be according to waste paper to be processed
Requirement and differently build.It can have hole 36, and can arrange with rectangle horizontal on the upside of base section plate 8
The rib 9 in cross section.
This some holes 36 can also be arranged in other base section plates 8 with rib 9,10 or 11.By this some holes 36,
Fiber can be drawn out of during the work of pulper so that pulper can work continuously.It is easily understood that this some holes 36
It is optional, and can arrange in the form of ownership of base section plate 8 when needed.In this way it is possible that
Identical pulper is used for batch run and be used for continuous print operation.
The most then base section plate 8 is provided with the blade rib 11 of triangular cross section.Connecing
The base section plate 8 is provided with bar-shaped rib 10.In many applicable cases, by all base section plates 8 in the same manner
Implement.But the most also will be advantageous that, a series of different base section plates 8 built are successively arranged at kneading trough
On bottom.Selection in FIG selects four kinds of different base section plates 8 to be illustrated just to explanation.These ribs 9,
The size of 10 and 11 and number are for other parameters by pulper Yu waste paper type matching to be processed.Base section plate 8
Other forms of implementation figure 18 illustrates.
As bottom parts, can arrange according to task and use flat planar plate or be equipped with cutter or hit
Hit the plate part of body.
Base section plate 8 can be implemented with or without the ground, hole 36 for material suspension being extracted out.(seeing Fig. 1)
If using band knife plate (i.e. with the base section plate 8 of rib 9 or 11), then according to the present invention, cutter excellent
Select geometry from axle midpoint with star or radially.In this way, it is ensured that cutter gap outwards connects
Continuous change is big, and is thus rinsed constantly.Therefore, material to be decomposed can not be attached between cutter.
When the hole 36 in the hole 36 of pulper to be passed through works continuously and to be taken out constantly by the material being broken down into fiber
When going out, this is particular importance.But, other geometric arrangement is also possible and is spendable.Cutter 9,11 several
What structure can be different according to task setting.
If to be smashed to pieces by big paper block, then tetragon cutter 9 or triangle tool are preferably used on base section plate 8
11.If strong friction (being decomposed into fiber) is applied on paper together with shear action, then it is preferably used such as circular rod 10
Or the geometry of semi-round bar.
But different plate configurations is also possible.Then, such as base section plate 8 with tetragon cutter 9 (is cut
Cut, shorten) can alternately replace with the base section plate 8 (kneading, friction) with pole 10.
In order to carry out the installation and removal of base section plate 8 very fast, these parts can be towards drive shaft
Preferred grafting rather than screw up on the inner side of 18, the most diametrically screws up.
Another modularity accessory of pulper according to the present invention is breaking ring 14, and it is the most preferably made up of some.
Breaking ring 14 is tightened in by screwed hole 15 at the overall diameter of base plate 16 when needed.There is multiple application, wherein can save this
Plant breaking ring.Here, also can bear fruit according to the modular arrangement of the pulper of the present invention.
In fig. 2, in constitutional diagram, show the standing part of the pulper according to the present invention.Again to point out at this
It is that all of single accessory can be mutually combined or can be removed.
It is clear that the groove of pulper is fixed on bearing block 17 with its base plate from Fig. 2.In addition it is clear that feel relieved
Ring 13 is responsible for location and the centering of base section plate 8, and can arrange breaking ring 14 outside base section plate 8.Breaking ring
All parts of 14 and all of base section plate 8 can be releasably securable to the end of pulper by Screw connector
On plate 16.It means that when converting waste paper type, such as can be by changing base section plate 8 and/or broken by saving
Ring 14 is by the operating characteristic of pulper and new waste paper type matching.
Show situation about illustrating as oblique view in Fig. 2 the most in the sectional views.
Figure 4 illustrates a deformation program, wherein base section plate 8 has rib 9.It means that protect in abrasion
Distance between lower limb and the base plate 8 of backplate 6 reduces, and due to " base section plate " unevenness and at abrasion protection plate
Gap between lower limb and the base section plate 8 of 6 obtains increase and dynamic shearing.
Figure 5 illustrates the rotation accessory shown in the assembling figure in assembled state, Fig. 1.
Thus, it clearly show that in Figure 5 according to the structure in the structure of the rotor of the present invention.The most clearly
It is that the configuration of abrasion protection plate 6 can be equally used for rotor and waste paper type matching to be processed.
In the case of being provided with the abrasion protection plate of reference 6 in Figure 5, this abrasion protection plate edge thereon is sawed
Form tooth dentation.In this way, the fracture of waste paper is further promoted.Other shown abrasion protection plate 6
There is straight top edge.
The cooperating for shape-ordinatedly transmitting moment of torsion of bolt 42 and wheel hub 3 is drawn equally from Fig. 5.In this way,
Alleviate the load of Screw connector 2.
The assembling figure according to Fig. 5 is shown in figure 6 in longitudinal section.
In the figure 7, amplify the most again and clearly show that the pancake rotor according to the present invention (does not i.e. have screw rod 1
Rotor) an embodiment.Being suitable for the most again, abrasion protection plate 6 can differently build.
According in the embodiment of Fig. 7, on " back side " of rotor blade 4, it is provided with the molding of wing to a certain extent
Part 35.The profiled member 35 of these wings reduces rotor flow resistance in waste paper, and thus brings according to this
The further reconstruction of the energy efficiency of bright pulper.If this accessory is no longer by mechanical system system in batch production later
Make, but its casting is the most economical, then this accessory 35 forms a unit with blade 4.
Certainly, the profiled member 35 of this wing can also differently build.In any situation, generally by plastics or its
The profiled member 35 of his material manufacture that is softer and that be easily worked is for protecting the spiral shell between rotor blade 4 and supporting body 5
Rotation attachment means.
Unrelated with the embodiment shown in accompanying drawing, have the following characteristics that according to the rotor of the present invention
The number of rotor blade 4 and supporting body 5 is arbitrary;But arrange and do not allow to cause imbalance, and therefore turn
How much blades 4 all should be all the time about placing axisymmetrically if being installed.
The number of rotor blade can be from the beginning of two blades, and it can also be until 8 blades or more.
The number of blade is relevant to the working speed of waste paper type, density of material and rotor.
The number for the installed surface of supporting body 5 on wheel hub 3 determines the maximum of the rotor blade that can install can
Can number.Can will be fixed in drive shaft 18 with the wheel hub 3 of such as 6,8,10 or more installed surface.
If such as using the wheel hub 3 with the installed surface for eight rotor blades 4, then rotor can be optionally
Work is carried out with 8,6,4 or 2 blades.
Under the design conditions for the wheel hub 3 of most six rotor blades, with 6,4,3 or at least 2
The method of operation of blade is possible.
When pancake rotor to carry out work with the highest rotating speed, the rotor operation with less rotor blade can be
Significant and be efficient.In this way, it can be ensured that the more preferable wake of suspended substance and avoid cavitation.
Again may be by being screwed on the front side of rotor blade 4 change rotor leaf by the abrasion protection plate 6 of different molding
The geometry of sheet 4.
If the big paper block being such as input in pulper to be smashed to pieces within the shortest time, then be preferably used as
Under abrasion protection plate: its lower limb is smooth, and by the most deeply towards the cutter plate being under it sinking come
Strong shear action is applied on big waste paper block.
Striking face is the most flatly implemented and be configured in the front side of abrasion protection plate, or has various geometry knot
The edge of structure or angle, in order to support to tear waste paper in the case of colliding these edges or angle.
Alternately at the abrasion protection plate on a rotor blade 4 under the configuring condition with even leaves number
The different distortion scheme of 6 is also possible.
If having damage or erosion portion after multiple working hours on abrasion protection plate 6, then it can be according to it
Geometry is reversed within the shortest time or is substituted by new plate.
Owing to the socket connection according to the present invention and/or spiral connect, within the shortest time, equally change one
Individual or multiple impaired rotor arms being made up of abrasion protection plate 6, supporting body 5 and rotor blade 4, wherein by abrasion protection plate
6, the rotor arm that supporting body 5 and rotor blade 4 are constituted is connected by described socket connection and/or spiral and is fixed on wheel hub 3.
In this way, the trimming (itself and time-consuming and cost association) to whole rotor can be saved.
It is also possible that by the rotor arm that is made up of abrasion protection plate 6, supporting body 5 and rotor blade 4 with relative to band
The height having the change of the base section plate 8 of rib 9,10,11 is fixed on wheel hub 3.By this layout, such as, can realize
: the rotor arm slided in cutter plate with bigger distance causes the good of pulper content to mix, and rotor subsequently
Arm closely slides in cutter plate, and by big paper block segmentation.
In order to change the diameter (greater or lesser) of rotor, it is not necessary to change whole rotor and additionally design size.Right
In change root diameter (the biggest or less 50% in the range of) be sufficient that, increase or reduce the straight of wheel hub
Footpath.The size of rotor blade can keep identical.Alternatively, wheel hub 3 can also keep constant and/or use other supporting bodies
5。
In order to water column that is resident and that only self rotate will not be formed on wheel hub 3, it is advantageous to will be from wheel hub
Two centrifugal bars that point sets out are arranged on upper (not shown) on the upside of wheel hub.
Along with the increase of root diameter, in the case of same rotational speed, improve the peripheral speed on blade outward flange, carry
High centrifugal effect, significantly improves the impact effects on outside impact edges in this way.
When the paper being difficult to decompose will be with time at a high speed towards impact edges throwing, and this configuration is favourable.Existed by paper block
Collision on impact edges, paper block is broken down into the least part and finally becomes ultimate fibre, and not damaged fiber.
Then, together with the turbulent flow being applied on paper block and friction, also make use of by the collision on impact edges of the paper block
Kinetic energy.
In exploded view and longitudinal section, the decomposition of the built modular according to the present invention is shown respectively in Fig. 8 to Figure 17
Five particularly suitable combinations of device or deformation program, and described below in.
As draw from Fig. 8, in this deformation program, there is no breaking ring.Base section plate 8 is configured to do not have rib
The smooth plate of bar.The wheel hub 3 of rotor itself and rotor is hexagonal, and is altogether provided with 6 rotor blades 4.This
Configuration may be used for low-density scope (LC) and Midst density scope (MC) but in all appearances labile contaminated give up
Paper.This waste paper becomes ultimate fibre by the strong turbulent flow of generation in aqueous suspension and reclaims.
Rotor has the working speed of about 450 revs/min to 600 revs/min.
Fig. 9 shows the sectional view by Fig. 8 illustrated above.
Abrasion protection plate 6 particularly protects rotor blade 4 or supporting body 5, and should be with little axial distance the end of at
Slide on portion's part plate 8.By the distance that this is little, it is ensured that line, sheet metal, wood, working of plastics or other waste paper pollute
Can not wedge under rotor blade.
Generally, these pulpers start with continuously-running duty.Start in mode this, it is intended to by equal for pulp suspension thing
Extracted out by hole (not shown in Fig. 8) in base section plate evenly, and the most again by water and waste paper the most also
And introduce in pulper with correct proportions.
The paper block and the impurity that are not yet broken down into fiber are kept here by aperture plate portion.Impurity is periodically by dirt lock
Remove.Paper block is pumped by the hole in part plate after it is broken down into ultimate fibre.
Showing the second configuration or the second deformation program in Figure 10 and Figure 11, wherein base section plate 8 is the most smooth
Ground is implemented.Wheel hub 3 only arranges two supporting bodies 5 and correspondingly with two rotor blades of abrasion protection plate 6.?
Being provided with screw rod 1 on the end face of wheel hub 3, its diameter is almost identical with the diameter of rotor blade 4.
The labile paper of all appearances that this configuration is particularly suitable in high density scope (HC) or cross gummed paper.When in waste paper
When having all possible pollutant, use this deformation program.It can use at continuous operation or in batch runs.
Working speed is typically 200 revs/min to 250 revs/min.
Because the paper that rotor kneading more or less is to be decomposed, so two blades are also enough.These blades are one
Determine to be used as in degree remover on smooth base section plate 8 or slide plate because screw rod 1 due to its may be less straight
Footpath and can not be such.Also it is also to be stressed that under this configuring condition, screw rod 1 and two rotor blades as remover work
The combination of 4 can be threaded together by the different elements of the Modular rotor according to the present invention and realize.
The waste paper of input stands strong friction on the long edge of screw rod 1, and this makes the fibre of separation membrane surface
Dimension becomes easy and supports the fiber of separation membrane surface.
By the change of the key dimension (height and diameter) of screw rod 1, can come for MC waste paper by simplest mode
Or HC waste paper prepares pulper.
Figure 12 and Figure 13 shows the 3rd configuration of the pulper according to the present invention.3rd configuration is substantially based on first
Deformation program (Fig. 8 and Fig. 9).But additionally it is mounted with breaking ring 14.On the tooth 37 of breaking ring 14, paper is by quickly turning
Dynamic rotor is cast and tears up.It means that fiber hydrolization is mainly carried out on the tooth 37 of breaking ring.Rotor is used as " centrifugal
Wheel " and the waste paper of fiber will be decomposed into radially outward towards tooth 37 throwing.When tooth 37 weares and teares, the breaking ring being screwed
14 can change by simple mode.
Here, rotating speed is 600-1000 rev/min, may also surpass in the case of the waste paper fibre of high moisture-proof is separated
Cross 1000 revs/min.
Showing the 4th configuration or deformation program in figures 14 and 15, it is based on deformation program 2 (Figure 10 and 11).No
Being same as deformation program 2, it is primarily adapted for clean and that type is pure waste paper.
Substituting the smooth base plate 8 according to Figure 10 and Figure 11, base section plate 8 is equipped with rib 9,10 and 11.Rotor fills
Having 6 blades altogether, thus when rotating every time, cut edge as much as possible or extruding margin occur in abrasion protection
Between rib 9,10 and 11 on the lower limb of plate 6 and base section plate 8.
In conjunction with Figure 14 it is noted that rib 9 to 11 radial arrangement, and the forward edge of rotor blade 4 non-radially
Orientation.In this way, extension between the lower limb and elongated elevated portion 9 of rotor blade 4, from inside to outside is obtained
Top clearance, this guarantees and in the top clearance of the opening of rib, enter paper block therein will not wedge, and at rib
Space between bar will not be filled, and be made by each rotor blade slipped over thereon and extrude to outward flange.
Figure 16 and Figure 17 shows the 5th configuration, its based on first configuration and the 3rd configuration (Fig. 8 and 9 and Figure 12 and
13).Additionally, substitute smooth base plate and employ the base section plate 8 with rib 9,10 and/or 11.They are supported will be useless
Paper is decomposed into fiber.
Certainly, show, by Fig. 8 to Figure 17, the embodiment that deformation program or configuration are merely exemplary.They are especially
To be shown, by change discrete component also or save discrete component can change in the scope of non-constant width according to this
The operating characteristic of the pulper of invention, and thus pulper can be mated for different waste paper types.
To illustrate that some typically configure further below, and it does not shows that in the accompanying drawings.Shown in the drawings is unnecessary
, because they are made up of the parts specifically described.
The configuration decomposed is carried out in LC and the MC scope at the standard waste paper that can normally decompose:
With the little, taper of smooth bottom parts (8) and the screw rotor (1) of quick rotation.For batch fortune
Row starts mode, in base section plate, there is no hole, porose for continuous operating band.
(recycling) mixed waste paper and mistake glue waste paper or the waste paper of overlay film and may be with dirt is separated when wanting fiber
The waste paper of dye thing, when they can become ultimate fibre recovery under strong turbulent flow very fast, this configuration is applicable
's.Except the strong turbulent flow in pulper, the friction on rotor edge to be increased.
For carrying out the configuration decomposed in the HC scope of the waste paper that can normally decompose:
Big screw rod 1 (taper or cylinder) and the slow of smooth base section plate 8 that band has been installed rotate
Pancake rotor.
In the configuration, pulper generally starts in batch runs, and therefore base section plate 8 does not has hole.
When want fiber separate (recycling) mixed waste paper with may be with the waste paper of pollutant, they are at the highest material
When starting to decompose into fiber on rotor edge under strong friction (but streaming slowly) under material density case, or it
When can be ground off from film surface rapidly by the fibre/fibre friction that exists in high-density environments, this configuration is
It is suitable for.
Another positive reason that high density is decomposed is to decompose for interfering material and the little impact of foreign body.Interfering material and
Foreign body due to the least in pulper stream and and inconspicuous smashed to pieces or split, and be to maintain its size and because of
This can be chosen well.Furthermore, it is possible to realize relative to identical structure size by high density pulper (HC pulper)
The handling capacity of twice to three times of low-density (LC) pulper.
But, energy requirement is along with throughput performance linear increase.
Configuration for carrying out decomposing in being very difficult to LC and the MC scope of waste paper of decomposition (moisture-proof):

Start mode, in base section plate 8, there is no hole, porose for continuous operating band.
When the waste paper of input does not comprise the biggest paper block and do not has mechanical contamination thing, this configuration is to be well suited for
's.
In order to ensure not comprise chaff interference and the pollutant of solid, the detection for chaff interference in upstream and being picked
Except meaningful.
By the pancake rotor rotated very fast, material suspension is by the high circumference speed on rotor blade end
Degree and very strongly accelerated and towards breaking ring in little distance location impact edges throwing.By at edge
On collision, paper block smashed to pieces the most more and more, until they have desired size, in order to be pumped and defeated
Give the size degradation device in downstream.
Configuration for carrying out decomposing in being very difficult to LC and the MC scope of waste paper of decomposition:
With the pancake rotor 1 of base section plate 8 and the quick rotation of breaking ring 14, this base section plate have rib 9,
10 or 11.Start mode for batch is operating, in plate part, there is no hole, porose for continuous operating band.
When the waste paper of input does not comprise the pollutant of machinery but comprises the most great paper block, this configuration is well
It is suitable for.In order to ensure the cleaning of waste paper, the detection for chaff interference in upstream and rejected meaningful.
Under this configuring condition, slide on abrasion protection plate 6 with the least gap by rib 9,10 or 11, big
Paper block is smashed to pieces the size for corresponding roughly to the mutual distance of rib 9,10 or 11 in less than 15 minutes.
Configuration for carrying out decomposing in being very difficult to the HC scope of waste paper of decomposition:
Slowly rotation flat with the big screw rod 1 (cylindrical or taper) on set and base section plate 8
Rotor 3, this base section plate has rib 9,10 or 11;
Start mode for batch is operating, in plate part, there is no hole, porose for continuous operating band.
When the waste paper of input does not comprise the pollutant of machinery, this configuration is well suited for.
In order to ensure cleaning, the detection for chaff interference in upstream and rejected meaningful.
This working method this have the advantage that, realizes big relative to identical structure by high density pulper (HC pulper)
The handling capacity of the twice to three times of little low-density (LC) pulper.But, energy requirement is along with throughput performance linear increase.
Another special feature of the present invention is changing the soonest and simply of base plate.
