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 den samme rotor og en annen stator mellom hvilke det er tilveiebrakt en sorteringssone, idet sortererens stator er utformet for å være siktliknende, og hvor innretningen omfatter en massetilførsel, et aksept-masseutløp 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 the same rotor and another stator between which a sorting zone is provided, the sorter's stator being designed to be sieve-like, and where the device comprises a mass supply, an acceptance mass outlet and a waste mass outlet.
Innretninger som for tiden er i bruk, er vanligvis adskilte defibratorer og sorterere. Det eksisterer også sådanne innretninger som både defibrerer og sorterer samtidig. Devices currently in use are usually separate defibrators and sorters. There are also 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 mye plass er nødvendig. Samtidig defibrering og sortering krever en tung og kostbar konstruk-sjon. Det er også et faktum at samtidig defibrering og sortering 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 that the price is high and a lot of space is needed. 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 dg 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 defibration and sorting of wood pulp in the paper and cellulose industry, but which does not have the generally widespread problems.
Innretningen ifølge oppfinnelsen er kjennetegnet ved at vinkelen mellom rotorakselens senterlinje og defibreringssonen er 75-105°, og vinkelen mellom sorteringssonen og rotorakselens senterlinje er 75-105°, og at defibreringssonen og sorteringssonen er beliggende i det samme masserom. The device according to the invention is characterized by the fact that the angle between the center line of the rotor shaft and the defibration 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 defibration zone and the sorting zone are located in the same mass space.
Som fordeler ved oppfinnelsen kan for eksempel nevnes at defibreringseffektiviteten kan reguleres trinnløst uten endring av sorteringsprosessen. Ved hjelp av fordefibrering kan fiberfnuggene eller fiberklumpene (fibre floes) disperge-res, hvorved bare partikler som ikke er egnet til å inkluderes i akseptmassen, fjernes. Dersom det ønskes, kan likeledes defibreringstrinnet eller sorteringstrinnet sløyfes fra innretningen. Når rotasjonshastighetsområdet velges på passende måte, muliggjør defibratorens fluidiseringsvirkning effektiv sortering i det samme konsistensområde. Advantages of the invention can be mentioned, for example, that the defibration efficiency can be regulated steplessly without changing the sorting process. With the aid of prefibration, 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 rotational speed range is selected appropriately, the defibrator's fluidizing action enables efficient sorting in the same consistency range.
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. The invention shall 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 henvisnings tallet 1, og defibreringsanordningens rotor er betegnet med henvisnings tallet 2, idet rotoren roterer slik navnet indikerer. Mellom rotoren og statoren er det avgrenset en defibreringssone i hvilken det materiale som inn-mates gjennom tilførselen 4, defibreres. Fra defibreringssonen går materialet videre til en sorteringssone som er avgrenset mellom rotoren 2 og sortererens stator 3. Sortererens stator 3 er utformet for å være siktliknende, slik at den slipper gjennom det defibrerte materiale. Den del av materialet som ikke kan gå gjennom sikten 3, unnslipper - under sentrifuge-ringskraftvi-rkning - gjennom en avfallsmasseutløp-tilkopling 6. Det defibrerte materiale som passerer gjennom sikten, strøm-mer ut gjennom en akseptmasseutiøp-tiikopling 7. 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. Between the rotor and the stator, a defibrating zone is delimited in which the material fed in through the supply 4 is defibrated. From the defibrating zone, the material passes on to a sorting zone which is defined between the rotor 2 and the sorter's stator 3. The sorter's stator 3 is designed to be sieve-like, so that it passes through the defibrated material. The part of the material that cannot pass through the sieve 3 escapes - under the action of centrifugation force - through a waste mass outlet connection 6. The defibrated material that passes through the sieve flows out through an acceptance mass outlet connection 7.
I innretningen ifølge oppfinnelsen for defibrering og sortering av materiale er vinkelen ct mellom defibreringssonen og senterlinjen av rotorens 2 aksel 8 75-105°, fortrinnsvis 90°. Vinkelen p mellom sorteringssonen og akselens 8 senterlinje er likeledes 75-105°, fortrinnsvis 90°. In the device according to the invention for defibrating and sorting material, the angle ct between the defibrating zone and the center line of the rotor's 2 axis 8 is 75-105°, preferably 90°. The angle p between the sorting zone and the center line of the axle 8 is likewise 75-105°, preferably 90°.
Det er også vesentlig ved oppfinnelsen at defibreringssonen og sorteringssonen er beliggende i det samme masserom 5. It is also essential to the invention that the defibration zone and the sorting zone are located in the same mass room 5.
Det er åpenbart for en fagmann på området at oppfinnelsen ikke er begrenset til det ut f ørelseseksempel som er vist i det foregående, og at den kan varieres innenfor rammen av det etterfølgende krav. It is obvious to a person skilled in the field that the invention is not limited to the exemplary embodiment shown in the foregoing, and that it can be varied within the scope of the following claim.
