Description

In pulper (defibrator), waste paper is carried out, with paper pulp, the device that fiber separates

Technical field

The present invention relates to a kind of for waste paper is carried out, with paper pulp, the device that fiber separates.

Background technology

Being disclosed a kind of device by US 2003/0173432 A1, it is for smashing to pieces garbage.

A kind of traditional pulper is disclosed, for waste paper is carried out fiber separation by DE 20 2,010 003 358 U1. Being disposed with lower tool on the downside of rotor, it is configured to Indexable insert, in order to improve the life-span.

Being disclosed a kind of device by WO 98/17393, it is inserted in container, i.e. oil can from below, and by being revolved Turn the cutter 40 driven to be smashed to pieces by the object within this container.

According to waste paper type or paper pulp type, need to determine before pulper (defibrator) is installed: should be Which which will use in density of material scope (part of the fibrous material in water) and by fiber separation rotor Waste paper type or paper pulp type carry out fiber separation (aufgeschlagen).

If to input, in order to this decomposition can be implemented, greatly by identical high efficiency by time changing fiber afterwards The reconstructional measures of scale, the most more exchanging rotor and/or rotor cage (bearing block) are necessary.

By according to assembly of the invention (pulper, defibrator), that be possible not only to avoid complexity and costliness Reconstruction, and the probability that user (paper plant) obtains is: in one apparatus the waste paper of different quality is carried out fiber separation. Can carry out without bothersome reconstructional measures from a type to another type of conversion.

According to the requirement of waste paper quality to be reclaimed, according to the pulper of the present invention can within the shortest time basis The requirement of new " waste paper type " is modified, and pulper carrys out work with the configuration for decomposing this waste paper optimum.

Modularly construct according to assembly of the invention, and be constructed so that all subelement grafting, and needing Fixed by bolt in the case of Yaoing.Bearing block with drive shaft correspondingly arranges and drive shaft correspondingly disposes, and makes Obtain all rotor configuration probabilities can be run.

Comprising additional optional element according to assembly of the invention, it is capable of reclaiming (recycling) economically in tradition Pulper in the waste paper type that can not decompose or can only wastefully and decompose with the highest energy requirement.Pass through This mode, extends the range according to assembly of the invention relative to traditional pulper.

Three kinds of density of material scopes (fibre density and the ratio of water) are distinguished, at pulping in these density of material scopes Machine carries out fiber hydrolization:

● the low consistency range (LC) between the density of material of about 4% to 6%

● the middle consistency range (MC) between the density of material of about 6% to 12%

● about 12% to more than the low consistency range (HC) between the density of material of 20%.

In LC scope and MC scope, there is also in pulper and good stream (Umtrieb).Undulation degree to be decomposed Material to be directed through by rotor as frequently as possible decomposing during the persistent period, in order to is captured by this rotor again and greatly Accelerate, and be thus broken down into fiber.Additionally, the strong eddy current in pulper similarly helps to be decomposed into fiber block Single fiber.

This for by standard waste paper (newspaper, magazine, corrugated cardboard garbage, the office waste of fast decoupled Etc.) carry out the pulper decomposed in the case of, the average resolving time is between 25 minutes to 50 minutes.

LC and MC pulper generally actuated in work continuously.Here, the fibrous material being decomposed by continually by Hole in bottom pulper is discharged and is carried for processing further.

With the big density of material fluctuation by the shortcoming of the Continuous Drive mode of the fibrous material discharge of decomposition being part. This is primarily due to waste paper inputs different with humidity for its component is not decomposed into fiber equably.

In the case of paper that is that largely printed, gluing or that coat, HC pulper is preferably used.Point The solution time is between 45 minutes to 90 minutes at this, or also can be considerably longer according to waste paper type.

In HC scope, in pulper hardly seen from stream (Umtrieb).Utilize at this, based on high material Whole paper to be entered through screw rotor in pulper and carry out kneading and by friction (self formed at this by material density Fibre frictoin (Eigenfaserreibung)) it is decomposed into fiber.HC pulper starts in mode at batch and works.

The paper of moisture-proof such as label paper, sanitary paper are as wiped bowl paper, kitchen rolls, wiping hands crimped paper or facing paper or false proof Paper all can not be decomposed in the common pulper with conventional rotors in LC scope, MC scope or HC scope economically.

(the expending energy) time of staying of a few hours is necessary, so as to by these paper in traditional pulper It is decomposed into and can be pumped out.

Ratio is not the most become with obtaining between fiber for the energy expense that can be sucked for being smashed to pieces by the waste paper of moisture-proof Example.These paper are the most generally incinerated or (as packaging material, pad material etc.) flow to low value application.

But, by the present invention, all these paper can be broken down in about 15 minutes to 30 minutes can be by Pump out, and the size degradation device in downstream can be fed to subsequently.

Summary of the invention

By according to assembly of the invention, all of waste paper (especially moisture-proof quality) can desirably be decomposed, I.e. paper plant is possible not only at random change waste paper kind, and can also install relevant rotor within the shortest time and join Put.

The replacing of rotor configuration can complete in less than one hour, and arbitrary rotor deformation scheme is all feasible.

Not existing can not be by the waste paper reclaimed according to assembly of the invention.

The even paper of moisture-proof can also be smashed to pieces to being taken out by according to assembly of the invention in less than 30 minutes Sucking-off, and separated by energy-conservation ground fiber, and then can be fed to size degradation device subsequently or dispersal device, it is used for Fully it is decomposed into ultimate fibre.

The pulper separated for waste paper carries out fiber with paper pulp according to the present invention includes groove and rotor, its rotor It is arranged in the drive shaft disposed rotationally.According in the pulper of the present invention, rotor and groove include at least two respectively The most interconnective individual parts or assembly so that obtain modular system.This modular system for groove and All including multiple element for rotor, it is broken that this modular system is capable of according to the present invention within the shortest time Pulp grinder is reconstructed so that it is suitable to other waste paper type.

In practice, the debugging time of 1 to 2 hour can be observed without any problems.The shortening of this reconstruction time and It is an important advantage of the pulper according to the present invention by the probability of pulper Yu various waste paper type matching.

The modular construction of the pulper according to the present invention relates equally to groove and rotor.

According to the present invention, include bottom and design in the case of the groove of sidewall that is connected with bottom, in bottom Annular slab can have been releasably secured.Annular slab can be implemented with single type, or is made up of some.These part quilts It is referred to as base section plate.

When being provided with multiple base section plate, each can individually being changed of these base section plates, its side Formula is to unclamp fixing bolt, and is taken off from the bottom of pulper by single base section plate.

In order to be fixed on bottom with required precision by base section plate, fitted bolt or cooperation are preferably used Connecting shaft set (Passhuelsen).

In order to arrange the operating characteristic of the pulper according to the present invention for different waste paper types, design It is to use the base section plate of different structure.

Then, base section plate can be drilled and/or have at least one rib.

When base section plate is drilled, pulper may be run continuously, because the fiber being decomposed passes through base section Hole in plate is discharged.

It is of course possible to when base section plate has hole, according to the pulper of the present invention in batch processing mode Run.This some holes the most additionally supports and is separated by waste paper fibre.It is generally directed to batch processing mode and uses the most with holes Base section plate.

Rib according to the present invention can have the cross section of triangle, tetragon or circle.Other cross section is also It is possible.

Rib is the most generally radially extending, manufactures because this simplifies and the combination of multiple base section plate is become Easily.Certainly it is also possible that rib becomes to be different from zero with the radial girders (Radiusstrahl) at the base plate midpoint through groove Angle, say, that they are to tilt (the angle α seeing in Figure 18).

Another element of " modular structure box " according to the present invention is breaking ring, and it releasably, preferably passes through bolt And/or be fixed on the bottom of groove with coordinating connecting shaft set.This breaking ring optionally uses.It is usually located at the overall diameter of bottom On so that rotor is in breaking ring inner rotation.It is internally provided with base section plate at breaking ring.

Breaking ring is generally made up of some due to operability and simply installed reason, and it is respectively by multiple Bolt is fixed on the bottom being screwed in kneading trough.The quantity of " tooth " that be arranged on breaking ring and its shape and relative to broken The layout of the rotor of pulp grinder provides other probability by the operating characteristic of the pulper according to the present invention with to be processed Waste paper type and its characteristics match.

In order to realize the most possible wearability of base section plate and rib, they are preferably by steel or stainless steel Make.When needed, material can also be attached ground surface hardening.

In another favourable expansion scheme of the present invention, the bottom of pulper is provided with centering ring (Zentrierring).Can be by optimal for base section plate centering possibly by centering ring.Additionally, by centering ring and rotor it Between gap optimization.

In another favourable expansion scheme of the present invention, rotor includes wheel hub, at least one but preferred multiple rotor Blade, the most each rotor blade screws up with supporting body, and each of these supporting bodies is connected with the wheel hub of rotor again.

In this way, rotor is also configured to modular system.In most of the cases wear and tear involved rotor Blade screws up to relevant supporting body so that it can be replaceable, if its mode is to unclamp when arriving the limit of wear Bolt stem.

It is also possible that rotor blade in terms of its shape, number and size with waste paper type matching to be processed.Made The number of rotor blade can change, its mode is by such as two, three, four, five or the most more turn Blades is fixed on according on the wheel hub of the rotor of the present invention.In this way, the operating characteristic of rotor is useless with to be processed The coupling of sheet type is also possible.

It is also possible that rotor blade is screwed up with supporting body in the position different relative to wheel hub.By this Mode, can regulate the axial distance between base section plate and the lower limb of rotor blade.Therefore, it can regulation in bottom Shearing between the lower limb of the rib of part plate and rotor blade or abrasion protection plate, and with waste paper type to be processed Coupling.

Although the abrasion protection plate 6 being preferably hardened is not necessarily such, however significant be in order at wear reason and There is such situation the most thereon.When the rib by base section plate extrudes or cuts, its particular importance.

Identical effect can realize by the abrasion protection plate screwed up on rotor blade.Rotor blade or its hold Carrier can be installed such that does not has thing can wedge under it.All cursors all should or the most closely the end of at Slide in the elevated portion of portion's part plate, or cursor height can be fixed in such a way that line or diaphragm or wood no longer may be used Can wedging.It is also possible that cursor height alternately low installation so that an arm prevents wedging.The height of next cursor Be installed so that and do not have thing to wedge, and all things on base plate, the fiber being predominantly located in the gap of rib and Film can be unwrapped, to avoid these gaps " to add " fibrous material.

It is also possible that the forward edge of rotor blade is the most radial oriented.Many applicable cases design , the forward edge of rotor blade becomes the angle α (seeing Figure 18) between 0 ° to ± 45 ° with the radial girders through rotor midpoint.

When such as the rib on base section plate is radial oriented, and the forward edge of rotor blade becomes with radial girders During the angle of 30 °, then " suddenly " do not shear between rib and the forward edge of rotor blade when rib overlaps. More precisely, the point that the lower limb of rotor blade and rib have minimum range thereon from inside to outside or from outside to inside moves Dynamic.In this way, it is achieved that according to the more stable operation of the pulper of the present invention, and this external rotor blade and rib Shear gap between bar obtains the radial component of shearing.This efficiency also causing improving the pulper according to the present invention.

When the wheel hub of supporting body itself Yu rotor screws up, obtain simplifying further and sweetly disposition safeguard.Then, It is for instance also possible that supporting body is fixed on rotor on differing heights.The number of supporting body can also be with desired The number matches of rotor blade.Then, such as in the case of being designed for fixing the rotor of six supporting bodies without any problems It is possible that the most only install two, three or four supporting bodies and rotor blade.

Another favourable expansion scheme of the present invention designs, the front side of rotor blade releasably secures There is abrasion protection plate.Worn and torn by maximum in the front side of rotor blade.The most particularly effective, by wear-resistant on front side of these The abrasion protection plate that steel, hard metal or other high abrasion resisting materials that material such as hardens is constituted manufactures.The most also may be used To set up again according to the present invention's within the shortest time by changing this abrasion protection plate simply when reaching the limit of wear The function of rotor.The configuration of abrasion protection plate also provides about the pulper according to the present invention and different waste paper types Further optimization possibility in terms of coupling.

In another favourable expansion scheme of the present invention, it is also possible to design, on the end face of wheel hub releasably Fixing own by screw rod (Schneckenwendel) known in the art, cylindrical or truncated cone-shaped.

Parts such as supporting body, rotor blade, the friction of the pulper of the described built modular according to the present invention Supporting body, abrasion protection plate and cylindrical or truncated cone-shaped screw rod and the base section plate differently built are permissible At random it is mutually combined, because all parts are releasable, is i.e. connected with each other especially by screwing up.Therefore, according to this The pulper of invention can be suitable for for known all waste paper types on the market.

Detailed description of the invention

Showing most important accessory the most in an exploded view, the pulper according to the built modular of the present invention can To be made up of these accessories.

First in the top of Fig. 1, show the most truncated cone-shaped screw rod 1.This truncated cone-shaped screw rod 1 has in centre Central canal, actual spirillum is had to be fixed on this central canal.

Central canal leads in substrate (not having reference), and substrate can be by Screw connector 2 and pancake rotor Wheel hub 3 screw up.Fastening 42 seen from (not having reference) on the downside of substrate, it is for being delivered to spiral shell by moment of torsion from wheel hub 3 On bar 1.

Then when waste paper type to be processed needs and the waste paper fibre in high density of material scope (HC) is divided From time, be suitable for screw rod 1.When need not screw rod, it is backed out simply and rotor is used as pancake rotor, and it is also referred to as star Rotor or centrifugal rotor.Rotor shown in FIG rotates counterclockwise at work.

Rotor includes wheel hub 3, and it has hexagonal cross section in an illustrated embodiment.Each at six outer surfaces On can screw on supporting body 5.However it is also possible that, will be less than six supporting bodies and thus less than six rotor blade rotations It is screwed on wheel hub 3.The number of rotor blade or supporting body 5 is a kind of probability according to the present invention, and it will be according to the present invention Operating characteristic and the waste paper type matching to be processed of rotor.

Rotor blade 4 is connected by supporting body 5 with wheel hub 3.Rotor blade 4 can be constructed as simple angle bar, as from Fig. 1 Middle drawn as, it screws up with supporting body 5.It can also be cast by steel or rustless steel, and has what fluid optimized Shape.

Elongated hole (not having reference) it is built with so that can regulate at rotor in wide scope in rotor blade 4 The forward edge of blade 4 and the angle between the radial girders at wheel hub 3 midpoint.Prove in many cases and be sufficient that, 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 Base plate, and it is used as centralising device or the positioning auxiliary device of base section plate 8.Base section plate 8 also be configured to the end 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):

With smooth base section plate 8 and the pancake rotor 1 of the quick rotation of breaking ring 14.Operating for batch 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.

Being sized so as to of each plate part so that each part can be replaced, without being risen by rotor or removing Rotor blade.

According in the embodiment of Figure 19, rotor blade 4 directly screws up with wheel hub 5.Supporting body 5 is in can be dispensed with.
