Description
Technical field
The present invention relates to a kind of broke treatment system of the broken for the treatment of the machine for the manufacture of paper web, board web, tissue webs or other web of fiber, wherein broken is dissolved at least one machine beater, to be collected at least one reception memorizer at this fibrous suspension produced and to be then directed through at least one cleaning equipment and multiple fiber disintegrating apparatus after machine beater.
Background technology
For the manufacture of usual install machinery beater on multiple positions of machinery below in the machine of web of fiber.After or before described machine beater is preferably in the process group of machine, such as, before or after being in drying nest, coating machine, calender etc.
As long as occur tearing in process group subsequently, then run web of fiber so far at machine at full speed and be directed under breadth width in the machine beater that is arranged in before this process group.
The web of fiber being dissolved into suspension at this is called broken.
Especially, relative many fiber disintegrating apparatus must be directed through at the paper of very moisture-proof with fibrous suspension when paper with plastic optical fibre.Except high cost of investment, the quantity of the fiber disintegrating apparatus that can be connected in series is restricted, because raise along with each fiber disintegrating apparatus creates pressure, this may cause the mechanical breakdown of the 4th or the 5th fiber disintegrating apparatus.
But because sometimes to require six times without agglomerate for reaching or even pass through for eight times, known fiber suspension is directed through clean and fiber disintegrating apparatus again.
This brings obvious energy consumption certainly.
Summary of the invention
Therefore, technical problem to be solved by this invention is the efficiency of the fiber shattering process improved when processing broken.
According to the present invention, the mode that this technical problem solves is, fibrous suspension imports at least one recirculation memory after cleaning equipment and at least one crude fibre disintegrating apparatus subsequently, turns back in this recirculation memory when being followed by least one fine fibre disintegrating apparatus after this recirculation memory and leaving the having at least at least partially of the fibrous suspension of last fine fibre disintegrating apparatus.
Because clean and crude fibre disintegrating apparatus is by pending fibrous suspension through only once, institute to produces significantly energy-conservation.In addition, crude fibre fragmentation has very low efficiency when again processing fibrous suspension.
The autotelic fine fibre that the fine fibre disintegrating apparatus of following in series connection achieves with minimum energy expenditure is broken.In addition, if the fineness of the fiber fragmentation in first time fine fibre disintegrating apparatus is the thickest, then at least this first fine fibre disintegrating apparatus especially can be made to be got around by bypass through afterwards by fibrous suspension first time and second time, and this has additionally saved energy.
For controlling this process, be followed by emptying memory after being proved to be the preferably last fine fibre disintegrating apparatus of advantageously fine fibre disintegrating apparatus, and the part turning back to recirculation memory of fibrous suspension is separated before this emptying memory.
Usually, recirculation memory is turned back at this whole fibrous suspension.After the fine fibre disintegrating apparatus through required quantity, then fibrous suspension can be directed in emptying receptacles.
But be also the expense that limiting pressure is set up, after recirculation memory, be followed by maximum three fine fibre disintegrating apparatus.At this, the fineness of fiber fragmentation also should keep constant from first to last fine fibre disintegrating apparatus or preferably increase.Broken efficiency can be improved by the classification of fineness, thus need less process or less fiber disintegrating apparatus.
If turn back in recyclable container by the only part of fibrous suspension, then the division after last fine fibre disintegrating apparatus of fibrous suspension flowing should be undertaken by sorting device.
During this situation, the part to the full extent without agglomerate arrives in emptying memory with the form of good slurry, and screenings is returned to recirculation memory.
Usually or at least advantageously whole fibrous suspensions leaving last fine fibre disintegrating apparatus is turned back in recyclable container sometimes through fine fibre disintegrating apparatus in first time.
For the restriction of expenditure, be sufficient that make fibrous suspension turn back in recyclable container for maximum twice in most of applicable cases.
After successfully processing fibrous suspension, recirculation memory is drained after last fibrous suspension returns.
In order to obtain simple structure, recirculation memory can be made completely not have mixing device.
According to a broke treatment system requirements of the present invention only recirculation memory.Certainly, by using multiple, preferably two recirculation memories, can the capacity of lifting means simply, wherein preferably only a recirculation memory is connected with fine fibre disintegrating apparatus subsequently.
During the fibrous suspension of recirculation memory is guided through fine fibre spraying equipment, other recirculation memory can be filled from reception memorizer.This means that fibrous suspension only turns back in the recirculation memory that is connected with fine fibre disintegrating apparatus.
Certainly, alternatively also tool is advantageous is that fibrous suspension turns back to another recyclable container from a recirculation memory by each fine fibre disintegrating apparatus respectively.
By make fibrous suspension until arrive required by fiber quality before guided back and forth by fine fibre disintegrating apparatus between recirculation memory, can ensure that each volume share of the fibrous suspension of recyclable container accurately carries out identical process.
Then, after last process, fibrous suspension is guided to emptying memory till corresponding recirculation memory is drained.During this process, other recirculation memory can be filled from reception memorizer.This has saved the time significantly.
Accompanying drawing explanation
The present invention is explained in detail hereinafter according to multiple embodiment.
In the accompanying drawings, Fig. 1 to Fig. 3 is the equipment schematic diagram according to different broke treatment system of the present invention.
Detailed description of the invention
In known broke treatment system, former, squeezer, to smear assembly relevant to machine beater respectively with process groups such as coiling machines.In machine beater, produce the as far as possible uniform pumpable suspension of concentration between 3.5% to 4.5% by water and shearing, then described suspension by transport pump to reception memorizer 1.
Fibrous suspension arrives the cleaning equipment 2 of the form such as with hydrocyclone from reception memorizer 1, the dirt that described cleaning equipment 2 may exist is removed from fibrous suspension.
Then, the crude fibre carrying out fibrous suspension in crude fibre disintegrating apparatus 3 is subsequently broken, its objective is and dissolves maximum agglomerate (fibre bundle).
Then fibrous suspension arrives one or more without in the recirculation memory 5 of mixing device from crude fibre disintegrating apparatus 3.
Equipment shown in Fig. 1 and Fig. 3 has an only recirculation memory 5.After this recirculation memory 5 is filled, fibrous suspension is directed through multiple fine fibre disintegrating apparatus 4 be in succession connected in series.Such as, equipment has two fine fibre disintegrating apparatus 4 in FIG, and has three fine fibre disintegrating apparatus 4 in figure 3.
Known machine can be used as crude fibre disintegrating apparatus 3 and fine fibre disintegrating apparatus 4, and its difference is only the fineness for the treatment of facility.
At this, fineness from first to the 8th fine fibre disintegrating apparatus 4 of fiber fragmentation should keep constant or preferably increase.
Until meet the requirements of the quality of fibrous suspension after last fine fibre disintegrating apparatus 4, in FIG whole processed fibrous suspensions is turned back to again in recirculation memory 5.Then from here, fibrous suspension is directed through fine fibre disintegrating apparatus 4 again.
Maximum the turning back to for twice in recirculation memory 5 of usual fibrous suspension is enough to.Then, whole fibrous suspension is imported in emptying memory 6 from last fine fibre disintegrating apparatus 4, and guide further from here for processing further or recycling.After recirculation memory 5 is emptying, this recirculation memory 5 can be filled again from reception memorizer 1.
Difference is therewith the sorting device 7 being also provided with the form with grader or pressure grader in figure 3 between last fine fibre disintegrating apparatus 4 and emptying memory 6.Good slurry through the sieve etc. of separation equipment 7 arrives in emptying memory 6, and is turned back to recirculation memory 5 by the screenings stopped on sieve.In this way, the only part of fibrous suspension to turn back in recirculation memory 5 and is again processed fine fibre disintegrating apparatus 4 in, and described part is not yet without agglomerate.The extra charge caused due to separation equipment 7 energy-conservationly to be compensated more by larger.
Illustrated broke treatment system has two recirculation memories 5 in fig. 2, but wherein only selectively makes each one to be connected with the fine fibre disintegrating apparatus 4 of three subsequently.Returning of fibrous suspension is only carried out in each other recirculation memory 5.This means, fibrous suspension until be directed through fine fibre disintegrating apparatus 4 back and forth before reaching the quality of hope between two recirculation memories 5.Can ensure that each volume fractiion of the fibrous suspension of recirculation memory 5 carries out the process of equal number by fine fibre disintegrating apparatus 4 in this way.
If the process of fibrous suspension in fine fibre disintegrating apparatus 4 terminates, then directed into emptying memory 6 till each recirculation memory 5 is emptying.During this period, the recirculation memory 5 of other sky is filled from reception memorizer 1 with pending fibrous suspension.
Then, immediately fibrous suspension can be directed through fine fibre disintegrating apparatus 4 from other recirculation memory 5.With this quick-replaceable, significantly enhance the capacity of equipment.
In addition, the strict separation of different broken quality is in succession this achieved.
In addition, Fig. 2 shows general spendable variant, makes the first fine fibre memory device 4 bypassed by bypass 8 through afterwards with second time in the first time of fibrous suspension.Which save energy, and be favourable especially when the fineness of the fiber fragmentation in the fiber disintegrating apparatus that the fineness of the fiber fragmentation in the first fine fibre disintegrating apparatus 4 is less than subsequently.
