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 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 another 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 separate 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 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 vinkelen mellom senterlinjen av akselen for defibratorens rotor og defibreringssonen er 5-45°, og vinkelen mellom sorteringssonen og akselen for sortererens rotor er 75-105°, og at defibrerings- og sorteringsprosessene finner sted i det samme masserom. The device according to the invention is characterized by the fact that the angle between the center line of the shaft of the defibrator's rotor and the defibration zone is 5-45°, and the angle between the sorting zone and the shaft of the sorter's rotor is 75-105°, and that the defibration and sorting processes take place in the same mass room .
Som fordeler ved oppfinnelsen kan for eksempel nevnes at defibreringseffektiviteten kan reguleres trinnløst uten å endre sorteringsprosessen. Ved hjelp av fordefibrering kan fiberfnuggene eller fiberklumpene (fibre floes) dispergeres, hvorved bare partikler som ikke er egnet for 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 Advantages of the invention can be mentioned, for example, that the defibration efficiency can be regulated steplessly without changing the sorting process. With the help of prefibration, the fiber flakes or fiber clumps (fiber 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 fluidizing action of the defibrator is enabled to be effective
sortering i det samme konsistensområde.sorting in the same consistency area.
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 henvisningstallet 1, og defibreringsanordningens rotor er betegnet med henvisningstallet 2, idet rotoren roterer slik navnet indikerer. Tilførsel av masse inn i rommet mellom defibratorens stator- og rotorblad skjer via en tilkopling (connector) 6. Vinkelen cx mellom def ibreringssonen og rotor-akselen 9 er 5 til 45°, fortrinnsvis 25°. I def ibreringssonen defibreres tremassen og fortsetter videre til sortereren som er anordnet i det samme masserom 5. In the figure, the defibrating device's stator is denoted by the reference number 1, and the defibrating device's rotor is denoted by the reference number 2, the rotor rotating as the name indicates. Supply of mass into the space between the defibrator's stator and rotor blades takes place via a connection (connector) 6. The angle cx between the defibration zone and the rotor shaft 9 is 5 to 45°, preferably 25°. In the defibration zone, the wood pulp is defibrated and continues to the sorter which is arranged in the same pulp room 5.
Sortereren består av en roterende rotor 3 og en stator 4 som er utformet slik at den er siktliknende. Den defibrerte del av materialet passerer sikten 4 og slipper ut gjennom en akseptmasseutløps-tilkopling 7. Den del av materialet som ikke passerer sikten 4, strømmer ut gjennom en avfallsmasse-utløps-tilkopling 8. Mellom rotoren 3 og sikten (statoren) 4 er det avgrenset en såkalt sorteringssone som danner en vinkel /3 med akselen 9, idet denne vinkel er mellom 75 og 105 , fort rinnsvis 90 . The sorter consists of a rotating rotor 3 and a stator 4 which is designed so that it is sieve-like. The defibrated part of the material passes the screen 4 and escapes through an acceptance mass outlet connection 7. The part of the material that does not pass the screen 4 flows out through a waste mass outlet connection 8. Between the rotor 3 and the screen (stator) 4, there is delimited a so-called sorting zone which forms an angle /3 with the axis 9, this angle being between 75 and 105, usually 90.
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 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 described above, and that it can be varied within the scope of the following claim.
