LAITE MASSAN KUIDUTTAMISEKSI JA LAJITTELEMISEKSI PAPERI- JA SELLULOOSATEOLLISUUDESSA - ANORDNING FÖR DEFIBRERING OCH SORTERING AV MASSA INQM PAPPERS- OCH CELLULOSAINDUSTR INAPPARATUS FOR FIBERS AND SORTING OF PULP IN THE PAPER AND PULP INDUSTRY - ANORDNING FOR THE DEFINITION OF SORTER IN THE PULP INQM PAPER AND CELLULOSE INDUSTRY
Tämän keksinnön kohteena on laite massan kuiduttamiseksi ja lajittelemiseksi paperi- ja selluloosateollisuudessa, johon laitteeseen kuuluu kuidutin, joka muodostuu roottorista ja staattorista, joiden väliin muodostuu kuidutusvyöhyke, sekä läjitin, joka muodostuu samasta roottorista ja toisesta staattorista, joiden väliin muodostuu lajitteluvyöhyke ja joka lajittimen staattori on muodostettu seulamaiseksi ja johon laitteeseen kuuluu massan syöttö, hyväksytyn jakeen poisto (aksepti) ja hylätyn jakeen poisto (rejekti).The present invention relates to an apparatus for defibering and sorting pulp in the pulp and paper industry, which apparatus comprises a defiber consisting of a rotor and a stator between which a defibering zone is formed and a conveyor consisting of the same rotor and another stator between which a sorting zone is formed and formed as a sieve and comprising pulp feed, accepted fraction removal (acceptance) and rejected fraction removal (reject).
Nykyisin käytössä olkevat laitteet ovat yleensä erillisiä kuiduttimia ja lajittimia. On myös olemassa laitteita, jotka sekä kuiduttavat että lajittelevat samanaikaisesti.The equipment currently in use is usually separate fiberizers and sorters. There are also devices that both fiberize and sort simultaneously.
Nykytekniikkaan liittyy kuitenkin monia ongelmia. Eräs ongelma on se, että laitteita tarvitaan useampia, jolloin hinta nousee korkeaksi ja tarvitaan paljon tilaa. Samanaikaisesti tapahtuva kuidutus ja lajittelu vaatii raskaan ja kalliin konstruktion. Niinikään samanaikaisesti tapahtuva kuidutus ja lajittelu eivät ole hallittavissa. Yleisesti kuidutus ja lajittelu tapahtuvat eri sakeudessa.However, there are many problems with current technology. One problem is that more equipment is needed, which makes the price high and a lot of space required. Simultaneous defibering and sorting requires a heavy and expensive construction. Likewise, simultaneous defibering and sorting are uncontrollable. In general, defibering and sorting take place at different densities.
Tämän keksinnön tarkoituksena on aikaansaada edellä kuvatun kaltainen laite massan kuiduttamiseksi ja lajittelemiseksi paperi- ja selluloosateollisuudessa, johon laitteeseen ei kuitenkaan liity nykyisiä ongelmia. Keksinnön mukaiselle laitteelle on tunnusomaista se, että roottorin akselin keskilinjan ja kuidutusvyöhykkeen välinen kulma on 75-105° ja lajitteluvyöhykkeen ja roottorin akselin keskilinjan välinen kulma on 75-105°ja että kuidutusvyöhyke ja lajitteluvyöhyke sijaitsevat samassa massatilassa.It is an object of the present invention to provide an apparatus for pulping and sorting pulp in the paper and pulp industry as described above, which, however, does not present the current problems. The device according to the invention is characterized in that the angle between the center line of the rotor shaft and the defibering zone is 75-105 ° and the angle between the sorting zone and the center line of the rotor shaft is 75-105 ° and that the defibering zone and the sorting zone are in the same mass space.

Keksinnön etuina voidaan mainita mm. se, että lajittelua muuttamatta voidaan kuidutustehokkuutta portaattomasti säätää. Esikuidutuksella saadaan kuituflokit hajoitettua, jolloin lajittelulla poistetaan ainoastaan akseptimassaan kelpaamattomat partikkelit. Niinikään laitteesta voidaan kytkeä tarvittaessa kuidutusvaihe tai lajitteluvaihe pois. Kun pyörimisnooeusalue valitaan sopivasti, mahdollistaa kuiduttimen fluidisoiva vaikutus tehokkaan lajittelun samalla sakeusalueeila.Advantages of the invention include the fact that the fiberization efficiency can be infinitely adjusted without changing the sorting. The pre-fiberization causes the fiber flocs to be dispersed, whereby only particles that are not suitable for the acceptance mass are removed by sorting. The fiberization stage or the sorting stage can also be switched off from the device, if necessary. When the range of rotation is appropriately selected, the fluidizing effect of the fiberizer allows efficient sorting with the same range of consistency.
Seuraavassa keksintöä selitetään yksityiskohtaisesti viittaamalla oheiseen piirustukseen, jossa kuvio esittää keksinnön mukaista laitetta massan kuiduttamiseksi ja la-jittelemiseksi.The invention will now be described in detail with reference to the accompanying drawing, in which the figure shows an apparatus according to the invention for defibering and sorting pulp.
Kuviossa on viitenumerolla 1 merkitty kuiduttimen staattoria ja viitenumerolla 2 kuiduttimen roottoria, joka nimensä mukaisesti on pyörivä. Roottorin ja staattorin väliin muodostuu kuidutusvyöhyke, jossa syötön 4 kautta syötetty materiaali kuituuntuu. Kuidutusvyöhykkeestä materiaali jatkaa lajitteluvyöhykkeeseen, joka muodostuu roottorin 2 ja staattorin 3 väliin. Lajittimen staattori 3 on tehty seulamaiseksi siten, että se läpäisee kuituuntuneen materiaalin. Se materiaalin osa, joka ei pääse seulan 3 läpi, poistuu keskipakovoiman vaikutuksesta hylätyn jakeen poistoyhteestä (rejekti) 6. Seulan läpi menevä, kuituuntunut materiaali poistuu hyväksytyn jakeen poistoyhteen 7 kautta (aksepti).In the figure, reference numeral 1 denotes the stator of the defiberist and reference numeral 2 denotes the rotor of the defiberist, which, as its name implies, is rotating. A defibering zone is formed between the rotor and the stator, where the material fed through the feed 4 is fibrous. From the defibering zone, the material continues to the sorting zone formed between the rotor 2 and the stator 3. The stator 3 of the sorter is made sieve-like so that it passes through the fibrous material. The part of the material which cannot pass through the sieve 3 leaves the discharge connection of the rejected fraction by centrifugal force (reject) 6. The fibrous material passing through the sieve leaves through the discharge fraction 7 of the approved fraction (acceptance).
Keksinnön mukaisessa laitteessa materiaalin kuiduttamiseksi ja lajittelemiseksi kuidutusvyöhykkeen ja roottorin 2 o akselin keskilinjan 8 välinen kulma on 75-105 , sopivimmin 90°. Lajitteluvyöhykkeen ja akselin keskilinjanIn the device according to the invention for defibering and sorting the material, the angle between the defibering zone and the center line 8 of the axis of the rotor 2o is 75-105, preferably 90 °. Sorting zone and axis centerline
o Oo O
8 välinen kulma fi on niinikään 75-105 , sopivimmin 90 .The angle fi between 8 is also 75-105, preferably 90.
Olennaista keksinnölle on myös se, että kuidutusvyöhyke ja lajitteluvyöhyke ovat samassa massatilassa 5.It is also essential for the invention that the defibering zone and the sorting zone are in the same mass state 5.

Alan ammattimiehelle on selvää, että keksintö ei ole rajoittunut ede1läesltettyyn sove1lutusmuotoesimerkkiin, vaan sitä voidaan vaihdella oheisen patenttivaatimuksen puitteissa.It will be clear to a person skilled in the art that the invention is not limited to the exemplary embodiment described above, but can be varied within the scope of the appended claim.
