Description
Oppfinnelsen angår en innretning for defibrering og sortering av tremasse ved papir- og celluloseindustri, omfattende en defibreringsanordning bestående av en rotor og en stator mellom hvilke det er tilveiebrakt en defibreringssone, og av en sorterer bestående av en annen rotor og en annen stator, idet sortererens stator er utformet for å være siktliknende, og hvor innretningen omfatter en massetilførsel, et akseptmasseutløp og et avfallsmasseutløp. The invention relates to a device for defibrating and sorting wood pulp in the paper and cellulose industry, comprising a defibrating device consisting of a rotor and a stator between which a defibrating zone is provided, and of a sorter consisting of another rotor and another stator, the sorter's stator is designed to be sieve-like, and where the device includes a mass supply, an acceptance mass outlet and a waste mass outlet.
Innretninger som for tiden er i bruk, er vanligvis separate defibratorer og sorterere. Det eksisterer også så-danne innretninger som både defibrerer og sorterer samtidig. Devices currently in use are usually separate defibrators and sorters. There are also such devices that both defibrate and sort at the same time.
Den eksisterende teknologi er imidlertid hemmet av tallrike problemer. Ett problem er at flere enheter er nødven-dige, slik at prisen er høy og det kreves mye plass. Samtidig defibrering og sortering krever e"n tung og kostbar konstruk-sjon. Det er også et faktum at samtidig defibrering og sorte-, ring ikke kan styres. Som regel skjer defibrering og sortering ved forskjellig konsistens. However, the existing technology is hampered by numerous problems. One problem is that several units are necessary, so the price is high and a lot of space is required. Simultaneous defibration and sorting requires a heavy and expensive construction. It is also a fact that simultaneous defibration and sorting cannot be controlled. As a rule, defibration and sorting take place at different consistencies.
Formålet med oppfinnelsen er å tilveiebringe en innretning av den innledningsvis angitte type for defibrering og sortering av tremasse ved papir- og celluloseindustri, men som ikke har de alminnelig utbredte problemer. The purpose of the invention is to provide a device of the type indicated at the outset for defibrating and sorting wood pulp in the paper and cellulose industry, but which does not have the generally widespread problems.
Innretningen ifølge oppfinnelsen er kjennetegnet ved at defibreringsanordningens og sortererens rotorer bare er forbundet med hverandre ved hjelp av en felles aksel og statorene er adskilte, og at statorene og rotorene er beliggende i det samme masserom. The device according to the invention is characterized by the fact that the rotors of the defibrating device and the sorter are only connected to each other by means of a common shaft and the stators are separated, and that the stators and rotors are located in the same mass space.
Som fordeler ved oppfinnelsen kan det for eksempel nevnes at defibreringseffektiviteten kan reguleres trinnløst uten endring av sorteringsprosessen. Ved hjelp av fordefibre-ring kan fiberfnuggene eller fiberklumpene (fibre floes) dispergeres, hvorved bare partikler som ikke er egnet til å være inkludert i akseptmassen, fjernes. Dersom det ønskes, kan likeledes defibreringstrinnet eller sorterings trinnet sløyfes fra innretningen. Når rotasjonshastighetsområdet velges på passende måte, muliggjør defibratorens fluidiseringsvirk-ning effektiv sortering i det samme konsistensområde. Oppfinnelsen skal beskrives nærmere i det følgende under henvisning til tegningen hvis ene figur viser en utfør-else av innretningen ifølge oppfinnelsen for defibrering og sortering av tremasse. As advantages of the invention, it can be mentioned, for example, that the defibration efficiency can be regulated steplessly without changing the sorting process. With the help of pre-fibration, the fiber flakes or fiber clumps (fibre floes) can be dispersed, whereby only particles that are not suitable for inclusion in the acceptance mass are removed. If desired, the defibration step or the sorting step can also be omitted from the device. When the rotation speed range is selected appropriately, the defibrator's fluidizing effect enables efficient sorting in the same consistency range. The invention will be described in more detail in the following with reference to the drawing, one figure of which shows an embodiment of the device according to the invention for defibrating and sorting wood pulp.
På figuren er defibreringsanordningens stator betegnet med henvisningstallet 1, og defibreringsanordningens rotor er betegnet med henvisningstallet 2, idet rotoren roterer slik navnes indikerer. Tilførsel av tremasse til rommet mellom defibreringsanordningens stator- og rotorblad skjer via en tilkopling (connector) 6. I rommet mellom bladene defibreres massen og fortsetter fremover inn i sortererens rotor 3 som er anordnet i det samme masserom 5. Defibreringsanordningens rotor 2 og sortererens rotor 3 har en felles rotas jonsaksel 9. I kraft av sin rotasjonsbevegelse slynger sortererens rotor 3 fibrene av passende størrelse gjennom sortererens stator 4 som er utformet slik at den er siktliknende, idet fibrene går ut gjennom en akseptmasse-tilkopling (accept connector) 7. De partikler som ikke passerer gjennom sikten 4, går ut gjennom en avfallsmassetilkopling (reject connector) 8, slik det er vanlig i sorterere. In the figure, the defibration device's stator is denoted by the reference number 1, and the defibration device's rotor is denoted by the reference number 2, the rotor rotating as the name indicates. Supply of wood pulp to the space between the defibrating device's stator and rotor blades takes place via a connection (connector) 6. In the space between the blades, the pulp is defibrated and continues forward into the sorter's rotor 3, which is arranged in the same pulp space 5. The defibrating device's rotor 2 and the sorter's rotor 3 has a common rotat ion shaft 9. By virtue of its rotational movement, the sorter's rotor 3 winds the fibers of suitable size through the sorter's stator 4, which is designed so that it is similar to a sieve, as the fibers exit through an accept connector (accept connector) 7. The particles which does not pass through the sieve 4, exits through a waste mass connection (reject connector) 8, as is usual in sorters.
Det er åpenbart for en fagmann på området at oppfinnelsen ikke er begrenset til det ut f ørelseseksempel som er beskrevet i det foregående, og at oppfinnelsen kan varieres innenfor rammen av det etterfølgende krav. Innretningens arbeidsmåte trenger derfor ikke å være slik som den som er beskrevet i det foregående, men innretningen kan arbeide ved at tilførselen utføres gjennom avfallsmasse-tilkoplingen 8, slik at det først finner sted en sorteringsproses s og avfallsmassen deretter defibreres. It is obvious to a person skilled in the art that the invention is not limited to the exemplary embodiment described above, and that the invention can be varied within the scope of the following claim. The device's working method therefore does not have to be as described above, but the device can work by the supply being carried out through the waste mass connection 8, so that a sorting process first takes place and the waste mass is then defibrated.
