LAITE MASSAN KUIDUTTAMISEKSI JA LAJITTELEMISEKSI PAPERI- JA SELLULOOSATEOLLISUUDESSA - ANORDNING FÖR DEFIBRERING OCH SORTERING AV MASSA INQM PAPPERS- OCH CELLOLOSAINDUSTRI NAPPARATUS FOR FIBERS AND SORTING OF PULP IN THE PAPER AND PULP INDUSTRY - ANORDNING FOR THE DEFIBRATION AND SORTING OF PULP INQM PAPER AND CELLOLOSA 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 toisesta roottorista ja toisesta staattorista, joiden väliin muodostuu lajitteluvyöhyke ja jonka lajittimen staattori on seulamainen 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, the apparatus comprising a defiber consisting of a rotor and a stator between which a defibering zone is formed, and a screen consisting of a second rotor and a second stator with a sorting zone between and sieve-like and comprising pulp feed, accepted fraction removal (acceptance) and rejected fraction removal (reject).
Nykyisin käytössä olevat 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 kuiduttimen roottorin akselin keskilinjan ja kuidutusvyöhykkeen välinen kulma on 5-45° ja lajitteluvyöhykkeen ja lajittimen roottorin akselin välinen kulma on 75-105 ja että kuidutus ja lajittelu tapahtuvat samassa massa-tilassa.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 fiberizer rotor axis and the defibering zone is 5-45 ° and the angle between the sorting zone and the screen rotor axis is 75-105 and that the defibering and sorting take place in the same mass state.

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 pyörimisnopeusalue valitaan sopivasti, mahdollistaa kui-duttimen fluidisoiva vaikutus tehokkaan lajittelun samalla sakeusalueella.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 rotational speed range is appropriately selected, the fluidizing effect of the fiberizer allows efficient sorting in the same consistency range.
Seuraavassa keksintöä selitetään yksityiskohtaisesti viittaamalla oheiseen piirustukseen, jossa kuvio esittää keksinnön mukaista laitetta massan kuiduttamiseksi ja lajit-telemiseksi.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. Massan syöttö kuiduttimen staattorin ja roottorin teräväliin, nk. kuidutusvyöhykkeeseen, tapahtuu yhteen 6 kautta. Kuidutusvyöhykkeen ja akselin 9 välinen kulmaIn 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. The feed of the pulp to the sharp distance between the stator and the rotor of the defiberizer, the so-called defibering zone, takes place together through 6.

on 5-45, sopivimmin 25. Kuidutusvyöhykkeessä massa kuituuntuu ja jatkaa edelleen saunassa massatilassa 5 olevaan lajittimeen.is 5-45, preferably 25. In the defibering zone, the pulp is fibrous and continues to the screen in the pulp space 5 in the sauna.
Läjitin muodostuu pyörivästä roottorista 3 ja staattorista 4, joka on tehty seulamaiseksi. Kuituuntunut ainesosa läpäisee seulan 4 ja poistuu hyväksytyn jakeen poistoyhteestä 7 (aksepti). Se ainesosa, joka ei läpäise seulaa 4, poistuu hylätyn jakeen poistoyhteen 8 kautta (rejekti). Roottorin 3 ja seulan (staattorin) 4 väliin muodostuu nk. lajitteluvyöhyke, joka muodostaa akselin 9 kanssa kulman^, joka on välillä 75- O o 105, sopivimmin 90.The applicator consists of a rotating rotor 3 and a stator 4 made sieve-like. The fibrous component passes through a screen 4 and exits the discharge fraction 7 of the approved fraction (accept). The component which does not pass through the sieve 4 is discharged through the discharge connection 8 of the discarded fraction (reject). A so-called sorting zone is formed between the rotor 3 and the screen (stator) 4, which forms an angle with the shaft 9, which is between 75 and 105, preferably 90.
Alan ammattimiehelle on selvää, että keksintö ei ole rajoittunut edelläesitettyyn sovellutusmuotoesimerkkiin, 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 above exemplary embodiment, but can be varied within the scope of the appended claim.
