Description
Oppfinnelsen vedrører en anordning ved skiveraffinar med et sentralt hulrom og med til hulrommet direkte tilkoplet mateskruepresse som leverer massen inn i hulrommet, hvilken mateskruepresse danner det sentrale hulroms ene endevegg og har et langsgående hulrom som danner en damputløpspassasje for damp som utvikles i raffinøren. The invention relates to a device at a disk refinery with a central cavity and with a feed screw press directly connected to the cavity which delivers the mass into the cavity, which feed screw press forms one end wall of the central cavity and has a longitudinal cavity which forms a steam outlet passage for steam developed in the refiner.
Ved en slik skiveraffinør reguleres konsistensen ved hjelp av skruepressen, som er koplet direkte til raffinøren. Massen mates ved hjelp av skruepressen mer eller mindre som en plugg direkte inn i et sentralt hulrom i skiveraffinøren. Under raffineringen utvikles det store mengder energi som går over i varme ved behandlingen. Dette utvikler damp mellom raffinørskivene. Noe av dampen vil unnvike sammen med den utgående masse, men noe av dampen må også ha anledning til å kunne unnvike tilbake. With such a disc refiner, the consistency is regulated using the screw press, which is connected directly to the refiner. The pulp is fed by means of the screw press more or less like a plug directly into a central cavity in the disc refiner. During the refining, large amounts of energy are developed which are converted into heat during the treatment. This develops steam between the refiner discs. Some of the steam will escape together with the outgoing mass, but some of the steam must also have the opportunity to escape back.
Fra SE-utlegningsskrift 403.916 er det kjent en skiveraffinør som nevnt innledningsvis. Den kjente skiveraffinør har således et sentralt hulrom hvor mateskruen danner den ene endebegrensning. Likeledes forefinnes det et langsgående hulrom som danner en damputløpspassasje for damp som utvikles i raffinøren. A disc refiner as mentioned at the beginning is known from SE specification document 403,916. The known disc refiner thus has a central cavity where the feed screw forms one end limit. Likewise, there is a longitudinal cavity which forms a steam outlet passage for steam developed in the refiner.
Fra WO 85/03730 er det kjent en skiveraffinør med et sentralt hulrom, men det er der ikke vist spesielle tiltak for spesiell utføring av den frigjorte damp. From WO 85/03730, a disc refiner with a central cavity is known, but there are no special measures shown there for a special performance of the released steam.
Oppfinnelsen tar utgangspunkt i den erkjennelse at det bør være et sentralt hulrom i skiveraffInøren, fritt for hindringer slik at den masseplugg som leveres av skruepressen virkelig kan ekspandere og utjevne seg, slik at derved damp kan unnvike allerede i denne fasen, ekspandere og gå inn i damputløpspassasjen. The invention is based on the recognition that there should be a central cavity in the disk refinery, free of obstacles so that the pulp plug delivered by the screw press can really expand and equalize, so that steam can escape already in this phase, expand and enter the steam outlet passage.
Ifølge oppfinnelsen foreslås det derfor en anordning som nevnt innledningsvis, hvilken anordning er kjennetegnet ved at det sentrale hulrom er fritt for hindringer mellom den nevnte ene endevegg og den motiiggende andre endevegg, med unntak av en eventuell masseriver, slik at det forefinnes et fritt sentralt hulrom hvor den av mateskruepressen leverte masseplugg kan ekspandere og utjevne seg før massen går inn mellom maleskivene, og ved at damputløpspassasjen dannes av en sentral langsgående boring i mateskruepressen. According to the invention, a device as mentioned in the introduction is therefore proposed, which device is characterized by the fact that the central cavity is free of obstacles between the mentioned one end wall and the opposing other end wall, with the exception of a possible mass tear, so that there is a free central cavity where the pulp plug delivered by the feed screw press can expand and equalize before the pulp enters between the grinding discs, and by the steam outlet passage being formed by a central longitudinal bore in the feed screw press.
Den eventuelle masseriver vil i denne forbindelse ikke kunne regnes som noen hindring. Masseriveren vil tvertimot medvirke til ekspandering og utjevning av massepluggen på en gunstig måte i det forøvrig frie, sentrale hulrom. In this connection, the possible mass ripper will not be considered an obstacle. The pulp scraper will, on the contrary, contribute to expanding and leveling the pulp plug in a favorable way in the otherwise free, central cavity.
I en fordelaktig utførelsesform, med en i det sentrale hulrom plassert masseriver, har presseskruen en sentral forlengelse som inneholder damputløpspassasjen og strekker seg inn i skiveraffinørens nevnte sentrale hulrom og Inn sentralt i masseriveren. In an advantageous embodiment, with a pulp grater placed in the central cavity, the press screw has a central extension which contains the steam outlet passage and extends into the said central cavity of the disc refiner and into the pulp grater centrally.
Oppfinnelsen skal beskrives nærmere under henvisning til tegningen som viser et snitt gjennom en skriveraffinør med direkte tilkoplet mateskruepresse. The invention shall be described in more detail with reference to the drawing which shows a section through a printer refiner with a directly connected feed screw press.
På tegningen er det vist en skriveraffinør 1 med to malesoner og en mateskruepresse 2. Begge disse aggregater er velkjente Innretninger for fagmannen og krever ingen nærmere omtale. Det skal dog bemerkes at den viste skiveraffinør 1 finnes beskrevet nærmere i SE-B 7808424-1. Det skal også vises til NO-patentsøknad 841840. Skruepressen 2 er også konvensjonell og består i hovedsaken av en konisk skrue 3 omgitt av en sil 4. The drawing shows a printer refiner 1 with two grinding zones and a feed screw press 2. Both of these units are well-known devices for the person skilled in the art and require no further discussion. However, it should be noted that the disk refiner 1 shown is described in more detail in SE-B 7808424-1. Reference should also be made to NO patent application 841840. The screw press 2 is also conventional and mainly consists of a conical screw 3 surrounded by a sieve 4.
I skiveraffinøren er det som vist et sentralt hulrom 5. Her befinner det seg en masseriver 6, som er montert på raffinør-ens rotoraksel 7. Som vist er den koniske presseskrue 3 forlenget inn i det sentrale hulrom 5 og inn sentralt i masseriveren 6. Denne forlengelse er betegnet med 8. Presseskruen 3 er hul, Idet den har en aksialt gjennomgående boring 9. Ved den i figuren høyre ende av presseskruen 3 er det anordnet en tverrboring 10 som krysser den sentrale langsgående boring 9 og derved tilveiebringer forbindelse med et kammer 11 i dette område. Dette kammer 11 står i forbindelse med en ledning 12. In the disc refiner there is, as shown, a central cavity 5. Here there is a pulp grater 6, which is mounted on the refiner's rotor shaft 7. As shown, the conical press screw 3 is extended into the central cavity 5 and centrally into the pulp grater 6. This extension is denoted by 8. The press screw 3 is hollow, as it has an axially continuous bore 9. At the right end of the press screw 3 in the figure, a transverse bore 10 is arranged which crosses the central longitudinal bore 9 and thereby provides a connection with a chamber 11 in this area. This chamber 11 is connected to a line 12.
Den viste og beskrevne skiveraffinør er beregnet for medium-konsistens-raffinering av kjemisk masse. Massen føres inn til matepresseskruen 2 som vist med pilen 13. Presseskruen 3 vil under drift være helt fylt med masse og leverer massen sentralt inn i ski veraf f inøren 1, dvs. inn i det sentrale hulrom 5. Ved høye energiinnsatser går store mengder av energien over i varme under behandlingen. Dette vil utvikle damp mellom raffinørskivene. Denne damp kan unnvike tilbake gjennom den sentrale boring 9 og tverrboringen 10 og videre gjennom kammeret 11 og ut gjennom dampledningen 12. Ved at damputløpskanalen, som dannes av boringen 9, strekker seg sentralt inn i masseriveren 6, oppnås det en viss separering av masse og damp i dette sentrale område, slik at massen ikke uten videre blåses ut med dampen. Også de radielle vegger 14 i skiveraffinøren bidrar til en viss slik separering. The disc refiner shown and described is intended for medium-consistency refining of chemical pulp. The pulp is fed to the feed press screw 2 as shown by arrow 13. The press screw 3 will be completely filled with pulp during operation and delivers the pulp centrally into the disc finer 1, i.e. into the central cavity 5. At high energy inputs, large amounts of the energy into heat during the treatment. This will develop steam between the refiner discs. This steam can escape back through the central bore 9 and the transverse bore 10 and further through the chamber 11 and out through the steam line 12. By the fact that the steam outlet channel, which is formed by the bore 9, extends centrally into the pulp grater 6, a certain separation of pulp and steam in this central area, so that the mass is not easily blown out with the steam. The radial walls 14 in the disc refiner also contribute to a certain separation.
Med oppfinnelsen oppnår man en styrt evakuering av dampen fra skiveraffinøren. Dampen kan ledes i rør dit den måtte være ønsket. With the invention, a controlled evacuation of the steam from the disc refiner is achieved. The steam can be piped wherever it is desired.
