Description
Foreliggende oppfinnelse angår en valseanordning ved en presse for avvanning av en fuktig fibermaterialbane, som for eksempel cellulosemasse o.l., hvor den materialbane som skal avvannes føres frem mellom to endeløse virebaner som føres frem i samme retning og løper om horisontalt lagrede valsepar, idet fibermaterialbanen og virebanene først løper gjennom et stort sett horisontalt kileparti som fortrinnsvis har innbyrdes horisontalt forsatte valser i de respektive valsepar, og deretter gjennom et presseparti. The present invention relates to a roller device at a press for dewatering a moist fiber material web, such as cellulose pulp etc., where the material web to be dewatered is fed forward between two endless wire webs which are fed forward in the same direction and run around horizontally stored pairs of rollers, the fiber material web and the wire webs first runs through a largely horizontal wedge section which preferably has mutually horizontally offset rolls in the respective roll pairs, and then through a press section.
En valseanordning for presser av denne art har til oppgave A roller device for presses of this nature has the task
på en enkel og hurtig måte å avvanne et fibermaterial. in a simple and quick way to dewater a fiber material.
Et kjent anlegg består av et antall valsepar hvor det mellom valsene føres frem en øvre og en nedre virebane. Virebanene er endeløse bånd mellom hvilke fibermaterialet føres frem. A known installation consists of a number of pairs of rollers where between the rollers an upper and a lower wire path are advanced. The wire courses are endless belts between which the fiber material is fed forward.
Ved hjelp av valsene presses virebanene mot fibermaterialet som derved avvannes. For å påskynde avvanningen omfatter anlegget et antall valsepar som danner et kileformet innløp til anlegget slik at trykket mot materialbanen økes for hver valse. Når avvanningsgraden øker, innebærer dette også en volumendring i fibermaterialet slik at også avstanden mellom valseparene må reduseres i fremføringsretningen. Denne type kileformet konstruksjon betegnes ved et slikt anlegg som våtparti eller registerparti. Heretter følger forpressepartiet som på kjent måte slutter med anleggets hovedpresse-parti. I forpressepartiet er valsene fortrinnsvis anordnet innbyrdes forsatt for oppnåelse av en bedre sammenpressing av fibermaterialet. Det forholdsvis godt avvannede fibermaterial kommer så inn i hovedpressepartiet som består av et valsepar med større diameter. Dette valsepar arbeider med et så høyt pressetrykk at ytterligere fuktighet presses ut fra fibermaterialet. With the help of the rollers, the wire webs are pressed against the fiber material, which is thereby dewatered. In order to speed up the dewatering, the plant includes a number of roller pairs that form a wedge-shaped inlet to the plant so that the pressure against the material web is increased for each roller. When the degree of dewatering increases, this also implies a volume change in the fiber material so that the distance between the pairs of rollers must also be reduced in the feed direction. This type of wedge-shaped construction is referred to in such a facility as wet section or register section. This is followed by the pre-press section, which in a familiar way ends with the plant's main press section. In the pre-pressing section, the rollers are preferably arranged staggered to achieve a better compression of the fiber material. The relatively well-dewatered fiber material then enters the main press section, which consists of a pair of rollers with a larger diameter. This roller pair works with such a high pressing pressure that additional moisture is pressed out of the fiber material.
En slik anordning i form av en dobbeltbåndpresse er eksempel-vis kjent gjennom det østerrikske patentskrift nr. 198.131. Ved videre utvikling av disse anordninger har det vært for-søkt ytterligere å øke den i og for seg allerede ganske høye kapasitet ved at virebåndets pressetrykk mot fibermaterialet økes jevnt og presseflaten ytterligere økes. Det skulle kunne være mulig ytterligere å øke antallet valsepar, men dette vil være uhensiktsmessig av den grunn at maskinen vil få alt for store dimensjoner. Det har derfor i stedet vært søkt å øke presseflaten og fordele trykket jevnt, samtidig som maskinens totale volum om mulig reduseres. Such a device in the form of a double belt press is known, for example, through the Austrian patent document No. 198,131. In the further development of these devices, attempts have been made to further increase the already quite high capacity by increasing the pressure of the wire band against the fiber material evenly and further increasing the pressing surface. It should be possible to further increase the number of roller pairs, but this would be inappropriate for the reason that the machine would have far too large dimensions. It has therefore instead been sought to increase the pressing surface and distribute the pressure evenly, while at the same time reducing the machine's total volume if possible.
Hensikten med foreliggende oppfinnelse er å videreutvikle The purpose of the present invention is to further develop
en valseanordning av den innledningsvis nevnte art, slik at det uten å øke maskinens dimensjoner kan oppnås en høyere avvanningskapasitet. a roller device of the type mentioned at the outset, so that a higher dewatering capacity can be achieved without increasing the dimensions of the machine.
I henhold til oppfinnelsen oppnås dette ved at pressepartiet omfatter et par valser som ligger den ene over den annen og har innbyrdes ulike diametre, idet den nedre valse har større diameter enn såvel den i fremføringsretningen nærmest foranliggende valse i kilepartiet som den øvre valse i pressepartiet, og at de to virebaner føres frem i en oppadrettet S-formet bane rundt de to presseparti-valser. Ved denne utformning er det mulig å avpasse pressetrykket i overens-stemmelse med den opptredende avvanning, samtidig som anleggets byggevolum kan reduseres vesentlig, idet virebanenes omslut-ningsvinkel kan gjøres i praksis maksimal. According to the invention, this is achieved by the press part comprising a pair of rollers which lie one above the other and have mutually different diameters, the lower roller having a larger diameter than both the roller closest to the front in the direction of advance in the wedge part and the upper roller in the press part, and that the two wire paths are advanced in an upward S-shaped path around the two press section rollers. With this design, it is possible to adjust the press pressure in accordance with the occurring dewatering, while at the same time the construction volume of the plant can be significantly reduced, as the wrapping angle of the wire courses can be made practically maximum.
Oppfinnelsen skal nærmere forklares under henvisning til vedføyde tegning, som viser en anordning med doble valser i pressepartiet. The invention will be explained in more detail with reference to the attached drawing, which shows a device with double rollers in the press section.
Figuren viser frem for alt de forskjellige valsers plassering i avvanningsanlegget. Til høyre i figuren er noen valser 1 montert i samme horisontalplan og over disse finnes et like antall valser 2, hvis avstand til de nedre valser 1 suksessivt avtar i fremføringsretningen for det material som skal avvannes. Valsene 1 og 2 har omtrent like stor diameter og avstanden mellom de øvre og nedre valser avtar helt frem til den siste valse 2 der mellomrommet er meget ubetydelig. Valsegrupperingen kalles for kileparti. Above all, the figure shows the location of the different rollers in the dewatering system. To the right of the figure, some rollers 1 are mounted in the same horizontal plane and above these are an equal number of rollers 2, whose distance to the lower rollers 1 successively decreases in the direction of advance for the material to be dewatered. Rollers 1 and 2 have approximately the same diameter and the distance between the upper and lower rollers decreases right up to the last roller 2 where the space between them is very insignificant. The roll grouping is called a wedge section.
Det presseparti som følger etter kilepartiet består av minst et valsepar 13, 14, der den ene valse 14 er anordnet over den annen valse 13. Den nedre valse 13 er derved lagret The press part that follows the wedge part consists of at least one pair of rollers 13, 14, where one roller 14 is arranged above the other roller 13. The lower roller 13 is thereby stored
slik at de omtrent horisontale deler av virebåndene 11,12 so that the approximately horizontal parts of the wire bands 11,12
som kommer fra kilepartiet kommer i kontakt med den nederste del av mantelflaten på valsen 13. Valsen 13 kan være noe større enn valsene 1,2 i kilepartiet. Valsen 14, som er lagret over valsen 13, har en noe mindre diameter enn valsen 13. Virebåndene 11 og 12 passerer sammen i en S-formet slynge om de to valser 13 og 14. Etter valsen 14, sett i virbåndenes løperetning, følger så de to drivvalser 5 og 6, which comes from the wedge part comes into contact with the lower part of the mantle surface of the roller 13. The roller 13 can be somewhat larger than the rollers 1,2 in the wedge part. The roller 14, which is stored above the roller 13, has a slightly smaller diameter than the roller 13. The wire bands 11 and 12 pass together in an S-shaped loop around the two rollers 13 and 14. After the roller 14, viewed in the direction of travel of the wire bands, follows the two drive rollers 5 and 6,
av hvilke drivvalsen 6 er slik lagret at det dannes en skrått nedadrettet utløpsbane for den avvannede masse. of which the drive roller 6 is stored in such a way that an obliquely downwards outlet path is formed for the dewatered mass.
Pressepartiet er således konstruert i høy grad kompakt. Da virebåndenes omslyngningsvinkel er meget stor, er det her til-strekkelig med bare ett valsepar 13, 14 for å oppnå det pressetrykk som er nødvendig for avvanning. Under valsen 14 finnes naturligvis en væskeoppsamlingsanordning som sikrer at den utpressede væske ikke faller ned på den underliggende valse 13. The press part is thus designed to be highly compact. As the winding angle of the wire belts is very large, it is sufficient here with just one pair of rollers 13, 14 to achieve the pressing pressure necessary for dewatering. Beneath the roller 14 there is of course a liquid collection device which ensures that the squeezed liquid does not fall onto the underlying roller 13.
Denne valseanordning ved presser for avvanning av masser This roller device at presses for dewatering pulp
har den fordel at kapasiteten kan økes vesentlig sammenliknet med hva tilfellet er ved kjente anordninger. Dessuten innebærer den kompakte konstruksjon den fordel at dårane nytteeffekt oppnås med en relativt liten maskin. has the advantage that the capacity can be increased significantly compared to what is the case with known devices. In addition, the compact construction has the advantage that the benefit effect is achieved with a relatively small machine.
