LAITE MASSAN KUIDUTTAMISEKSI JA LAJITTELEMISEKSI PAPERI- JA SELLULOOSATEOLLISUUDESSA - ANORDNING FÖR DEFIBRERING OCH SOR-TERING AV MASSA INOM PAPPERS- OCH CELLULOSAINDUSTRINAPPARATUS FOR FIBING AND SORTING PULP IN THE PAPER AND PULP INDUSTRY - ANORDNING FOR THE DEFINITION OF PULP IN THE PAPER AND PULP OF THE CELLULOSE INDUSTRY
Tämän keksinnön kohteena on laite massan kuiduttamiseksi ja lajittelemiseksi paperi- ja seiluloosateollisuudessa, johon laitteeseen kuuluu kuidutin, joka muodostuu roottorista ja staattorista, sekä läjitin, joka muodostuu toisesta roottorista ja toisesta staattorista 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 paper and cellulose industry, comprising an apparatus comprising a fiberizer consisting of a rotor and a stator, and a screen consisting of a second rotor and a second stator, the screen stator being screened and comprising a pulp feed. deletion (acceptance) and deletion of the rejected fraction (reject).
Nykyisin käytössä olevat laitteet ovat yleensä erillisiä kui-duttimia 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 1 ajittelemiseksi ;V: paperi- ja seiluloosateollisuudessa, johon laitteeseen ei . kuitenkaan liity nykyisiä ongelmia. Keksinnön mukaiselle laitteelle on tunnusomaista se, että kuiduttimen ja lajittimen roottorit ovat yhteydessä toisiinsa ainoastaan yhteisen akselin kautta ja staattorit ovat erilliset ja jotka staatto-rit ja roottorit sijaitsevat samassa massatilassa.It is an object of the present invention to provide a device as described above for pulping and drifting pulp, V: in the paper and cellulose industry, which device does not. however, related to current problems. The device according to the invention is characterized in that the rotors of the fiberizer and the sorter are connected to each other only via a common shaft and the stators are separate and which stators and rotors are located in the same mass space.
Keksinnön etuina voidaan mainita mm se, että lajittelua muuttamatta voidaan kuidutustehokkuutta portaattomasti säätää. Esikuidutuksella saadaan kuituflokit hajotettua, jolloin ! lajittelulla poistetaan ainoastaan akseptimassaan kelpaamattomat partikkelit. Niinikään laitteesta voidaan kytkeä tar- 2 76599 vittaessa kuidutusvaihe tai lajitteluvaihe pois. Kun pyöriini snopeusalue valitaan sopivasti, mahdollistaa kuiduttimen fluidisoiva vaikutus tehokkaan lajittelun samalla sakeusalu-eella.The advantages of the invention include the fact that the fiberization efficiency can be infinitely adjusted without changing the sorting. Pre-fiberization breaks up the fiber flocs, resulting in! sorting removes only particles that are not suitable for their acceptance mass. The fiberization stage or the sorting stage can also be switched off from the device if necessary. When the rotin snow range is appropriately selected, the fluidizing effect of the fiberizer allows efficient sorting over the same consistency range.
Seuraavassa keksintöä selitetään yksityiskohtaisesti viittaamalla oheiseen piirustukseen, jossa kuvio esittää keksinnön mukaista laitetta massan kuiduttamiseksi ja lajittelemiseksi.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 tapahtuu yhteen 6 kautta. Terävälissä massa kuituuntuu ja jatkaa edelleen samassa massatilassa 5 olevaan lajittimen rottoriin 3. Kuiduttimen roottorilla 2 ja lajittimen roottorilla 3 on yhteinen pyörimisakseli 9. Lajittimen roottori 3 heittää pyörimisliikkeensä ansiosta keskipakovoiman vaikutuksesta sopivan kokoiset kuidut lajittimen seulaksi muodostetun staattorin 4 läpi, jotka kuidut poistuvat hyväksytyn jakeen yhteen 7 kautta (aksepti). Ne partikkelit, jotka eivät mene seulan 4 läpi, poistuvat hylätyn jakeen yhteen 8 kautta, kuten lajittimissa yleensäkin.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. The pulp is fed into the sharp gap between the stator and the rotor of the defiberer through a total of 6 through. In the sharp gap, the pulp is fibrous and continues to the sorter rotor 3 in the same pulp space 5. The fiberizer rotor 2 and the sorter rotor 3 have a common axis of rotation 9. The sorter rotor 3 7 through (acceptance). Those particles which do not pass through the sieve 4 leave the discarded fraction together through 8, as is usually the case with sorters.
Alan ammattimiehelle on selvää, että keksintö ei ole rajoittunut edelläesitettyyn sovellutusmuotoesimerkkiin, vaan sitä voidaan vaihdella oheisen patenttivaatimuksen puitteissa. Niinpä laitteen toimintatavan ei tarvitse olla kuten edellä, vaan laite voi toimia myös siten, että syöttö tapahtuu ; rejektiyhteen 8 kautta, jolloin ensin tapahtuu lajittelu, ja sen jälkeen lajittelussa hylätty kuitujae (rejekti) kuidute-taan.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. Thus, the mode of operation of the device need not be as above, but the device may also operate in such a way that the feeding takes place; through the reject connection 8, whereby sorting first takes place, and then the fiber fraction (reject) rejected in the sorting is defibered.
