Description of drawings
Preferred embodiment be elaborated to of the present invention referring now to accompanying drawing, wherein:
Fig. 1 has schematically shown the side view of rotating cylinder pulper,
Fig. 2 has schematically shown the side view of pulper system,
Fig. 3 has schematically shown the side view of second kind of pulper system.
The specific embodiment
In Fig. 1, schematically shown the side view of the rotating cylinder pulper of simplifying very much 1, it has rotating rotating cylinder 2.In rotating cylinder pulper 1, be provided with feeder (Zuf ü hrblock) 4, fiber web suspension or material to be decomposed and the mixture of water are transported in the rotating cylinder pulper 1 through this feeder.The input 3 of aiming at feeder 4 is set in the rotating cylinder 2 of rotating cylinder pulper 1, and the fibrous suspension of waiting to be transported in the rotating cylinder pulper 1 passes through the inside that this delivery end arrives rotating cylinder 2.The relative other end at rotating cylinder 2 is provided with output 5, removes away from the inside of rotating cylinder 2 through this output from the waste material residue that rotating cylinder pulper 1 is discharged, to proceed processing.
The fibrous material that in rotating cylinder pulper 1, is included in the fibrous suspension is decomposed.Usually in rotating cylinder pulper 1, decompose like this fibrous material: the rotating cylinder 2 of along continuous straight runs (as shown in Figure 1) basically or the 5 downward-sloping slightly settings from input 3 to output is rotated around its axle; Wherein, The fibrous material that is transported to rotating cylinder 2 inside is along with the rotation of rotating cylinder 2 is risen; And in certain stage, drop to the bottom of rotating cylinder 2, and resolve into fiber simultaneously.According to the volume of rotating cylinder pulper 1, can the size of rotating cylinder 2 and rotating speed be confirmed as, the material that is transported to the input 3 of rotating cylinder 2 can be broken down into fiber well when arriving the output 5 of rotating cylinder 2.The needed device of rotation of rotating cylinder 2 for clarity sake, is not shown in Fig. 1.
As shown in Figure 1, the rotating cylinder 2 of rotating cylinder pulper 1 has along the flow direction of fibrous suspension: condensation means 6 is used for the fibrous suspension that is transported to rotating cylinder pulper 1 is concentrated or is used to improve pulp density; Immediately following condensation means 6 back be Knock-Down Component 7, be used for decomposing the fibrous material that is included in fibrous suspension or be used for rubbing or decompose or discharge the material that other is present in fibrous suspension; With flushing parts 8, be used for recycled fiber from the fibrous material that is decomposed at Knock-Down Component 7.
Be transported in the condensation means 6 that the input 3 of fibrous suspension through feeder 4 and rotating cylinder 2 in the rotating cylinder pulper 1 arrive in the rotating cylinders 2.Sheath 9 on the rotating cylinder 2 does not seal in the condensation means 6 of rotating cylinder 2; But has opening 10 therein; Liquid or water is through excluding in the fibrous suspension of these openings from be transported to rotating cylinder 2, and this is present in raising the pulp density of the fibrous suspension in the condensation means 6 of rotating cylinder 2.In rotating cylinder pulper 1, below condensation means 6 is filter tank 24, in condensation means 6, gets in this filter tank from rotating cylinder pulper 1 water of getting rid of and the fiber that is included in the water.
Water to be emanated in the filter tank 24 in the condensation means 6 of rotating cylinder pulper 1 and the fibrous material that will from water, separate can be for example be transported in the main pulper of rotating cylinder pulper 1 front in same pulper system, in Fig. 2 and Fig. 3, schematically show with arrow 25.Alternatively can also this suspension of mainly being made up of water be used in the flushing parts 8 that next will handle in rotating cylinder pulper 1, perhaps be transported to together in the identical process with the certified products of main pulper in order further to handle.Therefore, the size of the opening 10 of condensation means 6 is chosen as, makes the least possible pollutant through in the opening 10 arrival filter tanks 24.
In embodiment as shown in Figure 1, opening 10 is round, but the shape of opening 10 also can be varied to polytype and form.Therefore opening 10 also can be the opening of gap shape.
If the opening 10 of condensation means 6 is circular in the rotating cylinder pulper 1, then the diameter of circular open for example can be chosen as 5-25mm, is preferably 15-25mm, further is preferably 18-22mm.The size of opening 10 can be identical or different.Opening 10 in the rotating cylinder pulper 1 in the condensation means 6 can also be configured to the opening of thin-and-long.The opening of thin-and-long can be through the cramp bar formation along circumference or axial metal wire and support wires when making the condensation means of rotating cylinder pulper, perhaps forms through along circumference, axle or other directions the gap that on the jacket surface of condensation means, will form or opening being carried out machining more simply.The width in thin-and-long opening or gap for example can be 2-12mm, is preferably 3-8mm.Opening is big more, just can get over effectively liquid is excluded from fibrous suspension, and therefore improve the pulp density of fibrous suspension.But that the size that suitably limits opening can stop is bigger, can get in the filter tank 24 by hurtful pollutant.According to the intensity of sheath, can select the length of the thin-and-long opening of machining like this: the structural strength that makes it to guarantee sheath.Through selecting enough narrow gap, can prevent that the waste material residue of not expecting (the for example foamed plastics of fritter) from entering into the filter tank through opening.
The condensation means 6 of fibrous suspension from the rotating cylinder 2 of rotating cylinder pulper 1 continues to flow to the Knock-Down Component 7 in the rotating cylinder 2.That is to say, condensation means 6 with respect to Knock-Down Component 7 on the internal flow direction of fibrous suspension in rotating cylinder pulper 1 at the upper reaches of Knock-Down Component 7 side directly in the front that is arranged on Knock-Down Component 7.The sheath 9 of rotating cylinder 2 links up in the Knock-Down Component 7 of rotating cylinder 2, and rotating cylinder 2 can be at support (Ausleger) 11 or the lowering or hoisting gear 11 that have on the inner surface of rotating cylinder 2 on the sheath 9 that is fixed on rotating cylinder 2.The support 11 that is positioned on rotating cylinder 2 inner surfaces makes material to be rubbed move upward with rotating cylinder 2 when rotating cylinder 2 rotates, and falls back to the bottom of rotating cylinder 2 until material to be rubbed.Material to be rubbed is decomposed when falling or when each whereabouts, is decomposed more and more through shock effect.Wait that the part decomposition of rubbing material also can take place owing to the relative friction of fiber when rotating cylinder 2 rotates.Utilize the Knock-Down Component 7 in the rotating cylinder pulper 1 can accomplish the rubbing effect to fibrous material, wherein, the last fiber knot that is present in the pollutant in the fibrous suspension also can be decomposed.
For material to be rubbed is moved along the direction of going to output 5 from input 3 on rotating cylinder 2; As shown in Figure 1; That support 11 can be designed as orbit-shaped and the attitude setting to tilt makes support 11 tilt like this: material is moved towards the direction of output 5 from input 3 edges thus.Alternatively or additionally; Rotating cylinder 2 is turned forward a little; Make the input 3 of the output 5 of rotating cylinder 2 a shade below rotating cylinder 2, at this, material to be rubbed vertically continues whereabouts stretch journey with respect to rotating cylinder from the inner surface of rotating cylinder 2 along rotating cylinder 2 when falling.Rotating cylinder 2 can also in opposite direction or recede; Make the output 5 of the input 3 of rotating cylinder 2 a little less than rotating cylinder 2; But to move different backward be at this support that is obliquely installed 11 as shown in Figure 1 or lowering or hoisting gear 11 pending material further to be fed forward to pending material when tilting with rotating cylinder 2.Therefore, the angle of inclination of rotating cylinder 2 can be between-5 ° to 5 °, and at this, negative angle representes that rotating cylinder 2 recedes, and positive-angle representes that rotating cylinder 2 turns forward.On the inner surface of rotating cylinder 2, can also be along the ring-type intermediate plate 12 of its horizontally set around rotating cylinder 2 inner surfaces, it can limit transport flow through rotating cylinder 2 to the fibrous suspension in the rotating cylinder 2 too fastly.
The support 26 or the lowering or hoisting gear 26 that are similar to support 11 or lowering or hoisting gear 11 can also be set in the condensation means of rotating cylinder 2.Lowering or hoisting gear 26 can realize the concentrating of fibrous suspension effectively, because this device can pending material launch and material is come off from the wall of rotating cylinder 2, at this, water-fibre blend can pass through opening 10 and from rotating cylinder 2, discharge freely.In addition, utilize lowering or hoisting gear 26 can also realize from the input 3 of rotating cylinder 2 to the translocation of the output 5 of rotating cylinder 2 or make it more effective.
Knock-Down Component 7 in the rotating cylinder 2 of fibrous suspension from rotating cylinder pulper 1 continues to flow to the flushing parts 8 in the rotating cylinder 2, wherein, is washed out the waste material residue of fibrous material on remaining in rotating cylinder 2 inner surfaces.Flushing parts 8 for example can be configured to screen drum.In flushing parts 8; On the sheath 9 of rotating cylinder 2, be provided with letter sorting mouth 13 or letter sorting gap 13; As acceptable part, promptly certified products move to through letter sorting mouthfuls 13 or letter sorting gap 13 and are arranged in the certified products pond (Akzeptbecken) 14 of washing parts 8 belows size by the fiber of the size decision in letter sorting mouthfuls 13 or letter sorting gap 13 and water.Through for example nozzle 15 water is transported in the fibrous suspension in the flushing parts with forms lasting or periodic current (Wasserstrahlen) 16, can makes isolated received fiber increase from the remainder of fibrous suspension in flushing parts 8.The composition of the composition of fibrous material and the other materials that arrives with fibrous material (for example can not through the letter sorting mouth 13 of flushing parts 8 or all contaminations in letter sorting gap 13) is for example removed away from the output 5 of rotating cylinder 2 as the quilt of the effluent from process after flushing parts 8.
Flushing parts 8 in the rotating cylinder pulper 1 be that the diameter of circular letter sorting mouth 13 for example can be 5-15mm at this, be preferably 6-12mm.The whole length that the size of the letter sorting mouth in the flushing parts can equal to wash parts.Can also this letter sorting mouthful be set to, diminish gradually to output from the input of rotating cylinder.For example, the diameter of letter sorting mouth when beginning can be 8-12mm, begins to be reduced to 7-11mm then therefrom, and further is reduced to 6-10mm.The pulp density that arrives the material that washes parts from Knock-Down Component is higher at the initiating terminal of flushing parts; Based on this reason, the diameter of preferred letter sorting mouth is bigger at the start-up portion of flushing parts.If in the flushing parts, the pulp density of material descends to the end of flushing parts from the start-up portion of flushing parts gradually, and then the diameter of letter sorting mouth can reduce.Can the size of letter sorting mouth be chosen as; Make it keep open; Just avoid it to get clogged; And received material residue, just passing material (Akzeptmaterials) flows through this letter sorting effected accordingly, and the material that belongs to waste material is then avoided through flowing of letter sorting mouth.The letter sorting mouth of flushing parts can or be located according to arrangement or figure setting clocklike at random.For example, the letter sorting mouth of flushing parts can along rotating cylinder axially or circumferencial direction or constitute in proper order along other direction.
Condensation means can be processed with the opening of flushing parts like this: the diameter of opening is not changed on the thickness direction of sheath.These openings can also be configured to the hole of two borings: on the inner surface of rotating cylinder, bore aperture, and on outer surface, bore macropore.If do not penetrated from the larger-diameter hole that has that outer surface bored, then the minimum diameter in hole is confirmed by the hole that the inner surface from rotating cylinder bores.If streamwise enlarged openings in this way can improve the permeability of opening, and than diameter not with the opening of the wall thickness change of rotating cylinder, can avoid the obstruction of tilting to cause.
Condensation means can radially or on the position with respect to radial skew constitute with the hole or the opening of flushing parts.Utilize the oblique of opening; For example can make opening on the uplifted side of rotating cylinder more towards the direction of motion of the material that falls through lowering or hoisting gear, i.e. the direction of gravity is at this; Than opening with radial direction or hole, this can realize the permeability of rotating cylinder more effectively.
Replace the circle letter sorting mouthful or additionally here, the opening of thin-and-long can also be set in the flushing parts, this can constitute between formed gap through machining or by the line style material.The thin-and-long letter sorting mouth in the flushing parts or the width in gap for example can be 2-10mm, are preferably 3-8mm.The size in gap is chosen as: to avoiding obstruction, little of the pollutant that is included in the waste material can not be passed through greatly.The selection of the size in gap is corresponding with pending material.
Also be provided with support 27 or lowering or hoisting gear 27 in the flushing parts 8 in the rotating cylinder 2 of rotating cylinder pulper 1.Lowering or hoisting gear 27 rises pending material and mixes, and has improved fibrous material flowing to certified products thus.Make flushing a fluid stream (Waschstrahlen) aim at pending material equably thus again effectively from a plurality of directions.
In flushing parts 8, arrive the received part of the fibrous suspension in the certified products pond 14, i.e. the certified products of rotating cylinder pulper 1 for example can be sent back to the main pulper that is arranged in rotating cylinder pulper 1 front in the same pulper system.Alternatively can above-mentioned certified products be transported in the identical treating apparatus again of paper grade (stock) fibrous suspension, the certified products of main pulper are transported to this again in the treating apparatus.The certified products of rotating cylinder pulper also can its be transferred before in same process the certified products with main pulper be transported to special treatment device (Sonderbehandlung).
The rotating cylinder pulper part that rotating cylinder pulper 1 as shown in Figure 1 is different from previously known is; It has the condensation means 6 that is arranged on Knock-Down Component 7 fronts, and in condensation means 6, separates in the fibrous suspension of water from the rotating cylinder 2 that will be transported to rotating cylinder pulper 1 for the pulp density that improves fibrous suspension.Based on the condensation means 6 in the rotating cylinder pulper 1 as shown in Figure 1; Can the secondary pulper of this rotating cylinder pulper 1 as main pulper be used, promptly as the pulper that the waste material that comes autonomous pulper is handled again, in main pulper; Fibrous material is when pulp density is very low; For example when pulp density is 3-6%, be broken down into fiber, at this; Owing in rotating cylinder pulper 1, have a condensation means 6, the pulp density that arrives the fibrous suspension in the Knock-Down Component 7 of rotating cylinder pulper 1 still can be brought up in the scope to the favourable 8-18% of the Knock-Down Component of rotating cylinder pulper 17.Can the pulp density of the fibrous suspension in the rotating cylinder pulper 1 flushing parts 8 be reduced to about 2-5% through in fibrous suspension, spraying into water.
Therefore in the condensation means of rotating cylinder pulper, can reclaim the some fibre material.But mainly occur in the flushing parts through of the recovery of rotating cylinder pulper to fibrous material; Cause fibrous material in the Knock-Down Component of rotating cylinder pulper, just to decompose fully thus with remaining scrap material; In addition; Fibrous material decomposed or that discharge can be included in the fiber remnants or pars fibrosa of scattering, and the opening of the letter sorting face that fiber remnants that these scatter or pars fibrosa can be through the flushing parts in the rotating cylinder pulper is separated.
The diameter of the rotating cylinder 2 in the rotating cylinder pulper 1 is preferably 2-6m.The diameter of rotating cylinder 2 is typically chosen in the length that equals whole rotating cylinder.The diameter of rotating cylinder also can be according to the length of different parts and difference, perhaps even according to the length of rotating cylinder constantly changes.The length of the condensation means in the rotating cylinder 2 is preferably 1-15m, and the length of Knock-Down Component is preferably 3-25m, and the length of flushing parts is preferably 2-20m.The total length of rotating cylinder 2 is preferably 10-60m in the rotating cylinder pulper 1.According to pending material; The diameter of rotating cylinder and the length of rotating cylinder parts are chosen as; Make it possible to separate, decompose fiber and can be from the scrap material of the main pulper will being transported to the rotating cylinder pulper recycled fiber, and utilize the rotating cylinder pulper can reach desired production capacity.The length of preferred condensation means is the 15-35% of rotating cylinder 2 length, and the length of Knock-Down Component is the 30-50% of rotating cylinder 2 length, and the length of flushing parts is the 25-45% of rotating cylinder 2 length.
In Fig. 2, schematically shown the pulper system of seeing from the side 17.Pulper system as shown in Figure 2 has the rotating cylinder pulper 1 of main pulper 18 and 18 that connect with main pulper, as to be used for handling main pulper waste material.In main pulper 18, mix the formation fibrous suspension each other through making water and fibrous material.Water is transported in the main pulper 18 representes, fibrous material is transported in the main pulper 18 representes with arrow FM with arrow W.Fibrous material can for example be put in order bag ground or be transported in the main pulper 1 with less raw material batch.Except water and fibrous material, also import various chemical substances to main pulper.
Therefore main pulper 18 as shown in Figure 2 can be so-called horizontal pulper or vertical pulper; It has unshowned in Fig. 2, by motor-driven and the rotary body that vertically is provided with, this rotary body makes material movement pending in pulper through violent rotation.Fibrous material pending in pulper is broken down into fibrous suspension in pulper.Through material soak and the effect of chemical substance, by tearing of causing of rotary body, between the wall of fibrous material and pulper collision and realize the decomposition of fibrous material in pulper by the friction that the relative motion of material produces.When material to be decomposed by the regenerated fiber material, when for example being made up of the old paper of old cardboard or mixing, the pulp density of fibrous suspension can be between 1-10%, but be generally 3-6%.Also can use the discharging material or the paper pulp that in paper or production, reclaim to replace the regenerated fiber material as being transported to the fibrous material in the main pulper 18.
When the rotary body rotation of main pulper 18; In main pulper 18, can produce strong turbulent flow; Wherein, the particle (for example bigger fiber knot) heavier and be pulled to the edge of main pulper 18 with all contaminations (for example grit and composite and metal derby) that the regenerated fiber material brings as heavier material than fiber.Fibrous material descends downwards at the mid portion of main pulper 18 gradually.Bottom at main pulper 18 is provided with sieve plate, and the material that fully is decomposed into fiber can pass the opening of sieve plate.At this this opening can be circular, and its diameter typically is 5-20mm.Substitute at this circular open or additionally, can also on sieve plate, construct the opening of thin-and-long.The part of passing the hole in the sieve plate is called as the qualified residue of main pulper 18, and further is transported in the processing procedure again of fibrous suspension along the certified products passage 19 of main pulper 18.The processing procedure again of fibrous suspension for example can comprise the hole letter sorting or rough segmentation is chosen, sort in gap following closely or segmentation is chosen and be between the two or the centrifuge tube that is used to remove grit (Rohrschleuder) afterwards.After this process, can select to guide fibrous suspension to get in the short circulation (Kurzumlauf) of paper machine or board machine, so that when making paper or cardboard, use through ink removing device and/or settler.Through waste material conveyer (Rejektblock) 20 in the main pulper 18 and the waste channel 21 that schematically shows with arrow 21, can the waste material residue of composition that accumulates in fibrous suspension on main pulper 18 edges, that comprise all contaminations or main pulper 18 be transported in the rotating cylinder pulper 1 of secondary pulper as pulper system 17 as shown in Figure 2.Be included in that fibrous material in the waste material residue of main pulper 18 is decomposed and in rotating cylinder pulper 1 by further letter sorting, as shown in Figure 1.
In addition, also be provided with for the sake of clarity unshowned in the drawings salvage point (Ausschussauffangstelle) in the bottom of main pulper 18, the heaviest composition is fallen this place and is removed from this salvage point at any time in the fibrous suspension.
Waste material in the main pulper 18 separates when rubbing or moves in the fringe region of bottom, pond of main pulper, and this gravity effect through rotary body realizes with centrifugal force, and centrifugal force is by the generation that rotatablely moves of the material to be rubbed through the rotary body generation.When waste material accumulated in the fringe region in pond, waste material will be eliminated through the waste material exporter (Rejektausleitblock) in the pulper.Can select waste material to derive the time like this, the scrap material that major part is accumulated on the bottom, pond of main pulper is eliminated from the pond of main pulper, and keeps the material as certified products simultaneously as much as possible.If the regenerated fiber material that utilizes main pulper to handle comprises seldom or considerably less waste material, can be for example with 5 minutes space brooming waste material.If the regenerated fiber material that utilizes main pulper to handle comprises more scrap material, can correspondingly shorten the time between each waste material derivation, for example 2 minutes.Can according to circumstances find out time in the desirable time interval between each waste material derivation, and suitably adjust longlyer as requested, at this, this time interval can change between 0 to 15 minute.To the rotating cylinder pulper, can select the empty stage of the waste material of main pulper like this: make main pulper and rotating cylinder pulper do as a whole operation ideally to decomposition, recovery and the production capacity of fibrous material.That is to say that main pulper mainly is to move continuously, the waste material of main pulper is not timing ground or be eliminated continuously then.
In pulper system 17 as shown in Figure 2; Main pulper 18 is more placed on the highland than rotating cylinder pulper 1 on the vertical direction of pulper system 17; At this, the potential energy that is produced by related difference in height is enough to make the waste material of main pulper 18 to be transported in the rotating cylinder pulper 1.Under situation as shown in Figure 2, the waste material valve 22 that schematically shows is set in the waste channel 21 of main pulper 18, this valve keeps shut usually, periodically or does not termly open, and is transported in the rotating cylinder pulper 1 in order to the waste material with main pulper 18.For the sake of clarity, the device that is used to open and close the waste material valve that in Fig. 2, the professional is not shown and is known.
In pulper system 17 as shown in Figure 2, rotating cylinder pulper 1 moves by this way: waste material valve 22 is opened provisionally, wherein, all carries the waste material in a certain amount of main pulper 18, in order in rotating cylinder pulper 1, to handle at every turn.The rotating cylinder pulper is the work of continuity ground for example, thereby can for example open the waste material valve constantly, and the waste material valve can continue to open during this period, thereby more pollutant is transported in the rotating cylinder pulper.
In Fig. 3, schematically shown second kind of pulper system seeing from the side.The miscellaneous part of pulper system 17 as shown in Figure 3 is corresponding with pulper system 17 as shown in Figure 2, has only main pulper 18 and rotating cylinder pulper 1 along being positioned on the same plane on the vertical direction of this pulper system 7., utilize waste material pump 23 that the waste material in the main pulper 18 is transported in the rotating cylinder pulper 1 here, waste material pump 23 is used for provisionally or termly the waste material of main pulper 18 is transported to rotating cylinder pulper 1.The device of the function that is used to control waste material pump 23 for the sake of clarity, is not shown in Fig. 3.
In pulper system 17 as shown in Figure 3, rotating cylinder pulper 1 is worked by this way: not timing ground uses waste material pump 23, wherein, all carries the waste material in the main pulper 18 of some, in the rotating cylinder pulper, to handle at every turn.The rotating cylinder pulper can also for example be worked continuously, thereby the waste material pump was all moved with lower rotating speed in the whole time, and the waste material pump can also high rotational speed move during this period, so that more pollutant is transported in the rotating cylinder pulper.
Pulper system as shown in Figures 2 and 3 comprises main pulper 18 and the rotating cylinder pulper 1 that in Fig. 1, schematically shows, and this rotating cylinder pulper 1 works as secondary pulper in pulper system 17.But sorting ability according to rotating cylinder pulper 1; Also can use the secondary pulper of 1 while of unique rotating cylinder pulper as a plurality of main pulpers 18; In these main pulpers 18; Can have one or morely be positioned on the identical plane on the vertical direction of pulper system 17, or be higher than rotating cylinder pulper 1.Very well be applicable to bigger or very large output like Fig. 2 or pulper system 17 shown in Figure 3.
In the pulper system of the secondary pulper with a plurality of series connection in early days (ability of these secondary pulpers relatively low and have rotary body, sieve plate and drum filter that maybe be following closely), relevant secondary pulper and rotating cylinder pulper can utilize the rotating cylinder pulper that comprises condensation means as shown in Figure 1 to replace.Can obviously reduce the quantity of the single assembly of pulper system thus.The conventional secondary pulper that is equipped with rotary body and sieve plate in practice even can not seal receiving the scrap material from a plurality of main pulpers, and does not receive the material from the main pulper of processing different material.Through reducing number of devices, simplified the allocation plan of workplace, and dwindled the gross area in the space that is used for plant maintenance.Through reducing number of devices; The instrument and meter that is used for control appliance and automated system and software that maybe needs have also been simplified; At this, be to equipment itself or its control and concerning the optimization of whole pulper systemic-function, all reduced the time that required instrument and meter and automated system are installed and debugged.Through reducing number of devices, the quantity of process pipe-line system is become still less.In addition, when the decomposition of a part of fibrous material occurs in the rotating cylinder pulper, than before the size in pond can also make the size in pond of main pulper littler.
In the rotating cylinder pulper, can effectively fibrous material be separated from composite, and remove composite, and need not to reduce the piece footpath of the composite skin in the waste material.On the contrary, be equipped with the secondary pulper of traditional rotary body that composite is resolved into less fritter, thereby the part composite is converted into certified products, this is not to hope.Handle with the secondary pulper that utilizes other and to compare; The sharpest edges of waste material treatment material are in the rotating cylinder pulper; In processing procedure, can the composite skin not resolved into too little small pieces; Thereby can the composite than bulk be removed away as the waste material in the rotating cylinder pulper, and avoid composite when papermaking, to get in the processing procedure thus again, this might bring injury in processing procedure again.
Be division or the decomposition of fibrous material all to take place and in main pulper or in the rotating cylinder pulper with fibrous material fragmentation or defibre (Defibrierbarkeit); Form fiber freely, fiber knot and less fibre material sheets thus, thereby make the material major part of handling via pulper pass the lip-deep opening of sieve plate in the pulper as certified products from fibrous material.To being reached for example 90-98% by the decomposition efficiency of the fibrous material of pulper acceptance.To the decomposition of the remainder of fibrous material can be in processing procedure again by means of occur in the container washing
and different machinery again treatment progress realize.The waste material that the undecomposed fiber of part can also for example be chosen as rough segmentation is transmitted back in the main pulper.
The professional is noted that basic thought of the present invention can adopt all kinds and mode to implement in technical development.Therefore the present invention and embodiment thereof are not limited only to the above embodiments, but can change within the scope of the claims.
