I figurene og i den folgende beskrivelse er de samme henvisningstall blitt anvendt for å betegne samme eller analoge deler gjennomgående. In the figures and in the following description, the same reference numbers have been used to denote the same or analogous parts throughout.
I henhold til fig. 1 - 3 Pa tegningene omfatter pressen etter en forste utforelsesform av oppfinnelsen en vertikal- for-presse eller et forpressingstrinn 1, og en horisontalt sluttpresse eller et sluttpressetrinn 2. Sluttpressen mates av forpressen, hvilket innebærer at for-pressens 1 utlop er sluttet til og munner ut i sluttpressens 2 innlop. According to fig. 1 - 3 In the drawings, the press according to a first embodiment of the invention comprises a vertical pre-press or a pre-pressing stage 1, and a horizontal final press or a final pressing stage 2. The final press is fed by the pre-press, which means that the outlet of the pre-press 1 is connected to and opens into the 2 inlets of the final press.
For-pressen 1 omfatter en innlopstrakt 3 til hvilken våt masse f.eks. betesnitt, tilfores ved hjelp av en (ikke vist) mateskrue eller liknende, et par i hverandre inngripende skruespindler 4 og 5 eller liknende, som er forsynt med skrueblader eller vinger, en perforert silmantel 7> en ytre kappe 8, et væskeoppsamlingstrau 6 og drivorganer for omdreining av spindelene 4 °g 5* The pre-press 1 comprises an inlet funnel 3 to which wet mass e.g. beet section, is fed by means of a (not shown) feed screw or the like, a pair of mutually engaging screw spindles 4 and 5 or the like, which are provided with screw blades or wings, a perforated sieve jacket 7 > an outer jacket 8, a liquid collecting trough 6 and drive means for turning the spindles 4 °g 5*
Drivorganene omfatter en drivmotor 9> en girkasse lo, i hvilken motorens hastighet reduseres, og rette tannhjul 11. På grunn av disse tannhjul roterer spindlene 4 og 5 åpenbart i motsatt retning i forhold til hverandre. Skruespindlen 4 har hoyregående og skruespindelen 5 venstregående vinger eller gjenger. Den perforerte silmantel 7 har tilnærmelsesvis samme form som mantelen 8 som er vist i fig. 2, og omslutter skruespindlene 4 °g 5 med ubetydelig spillerom. Et mellomrom dannes mellom den perforerte silmantel 7 °6 den ytre kappe 8. The drive means comprise a drive motor 9 > a gearbox 10, in which the speed of the motor is reduced, and spur gears 11. Because of these gears, the spindles 4 and 5 obviously rotate in the opposite direction in relation to each other. The screw spindle 4 has right-hand and the screw spindle 5 left-hand wings or threads. The perforated sieve mantle 7 has approximately the same shape as the mantle 8 shown in fig. 2, and surrounds the screw spindles 4 °g 5 with negligible clearance. A space is formed between the perforated sieve jacket 7°6 and the outer jacket 8.
Den våte masse som innfores i forpressen i kloften mellom skruespindlene 4 °g 5 samt silmantelen 7 gjennom innlopstrakten 3» fremmates under sammenpressing og samtidig utvanning av skruespindlene 4 °g 5- Væsken som utpresses av massen gjennom den perforerte silmantel 7> oppsamles i trauet 6. På grunn av de to skruespindlers vingers innbyrdes inngrep, blir massen meget godt omrort og hindres også fra å ta del i skruespindlenes rotasjonsbevegelse, hvilket innebærer at massen bibringes en gunstig aksiell bevegelsesretning. En forholdsvis hurtig sammenpressing under det innledende pressetrinn og en effektiv fylling av selve pressen istandbringes herved, hvilket sikrer en hoy volumetrisk virkningsgrad. Foruten dette frembringes et overtrykk allerede ved sluttpressens 2 innlopsende, hvilket be-fordrer massens avvanning. The wet mass that is fed into the pre-press in the gap between the screw spindles 4 °g 5 and the sieve jacket 7 through the inlet funnel 3" is fed forward during compression and simultaneous dilution by the screw spindles 4 °g 5- The liquid that is squeezed out of the pulp through the perforated sieve jacket 7> is collected in the trough 6 Due to the mutual engagement of the two screw spindles' wings, the mass is very well stirred and is also prevented from taking part in the rotational movement of the screw spindles, which means that the mass is given a favorable axial direction of movement. A relatively rapid compression during the initial pressing step and an efficient filling of the press itself are thereby established, which ensures a high volumetric efficiency. In addition to this, an overpressure is produced already at the inlet of the final press 2, which facilitates the dewatering of the mass.
Hoved- eller slutt-pressen 2 som mates av forpressen 1 og også er sluttet til væskeoppsamlingstrauet 6 ved hjelp av et ror 13, omfatter en eneste skruespindel 14 som fortrinnsvis har en tilnærmelsesvis parabolisk kontur og er forsynt med skruegjenger eller vinger 14, en perforert silmantel l6, som har sirkulært tverrsnitt etter hele sin lengde og fortrinnsvis er sylindrisk, et flertall fast-holdelses- eller motholds-organer 2o, som er beliggende i kloften mellom skruespindelen 14 og silmantelen 16, en ytre kappe som omgir skruespindelen 14 og ligger i avstand fra denne, en dreieventil eller et dreiespjell l8 fortrinnsvis av rosett-typen og forsynt med et reguleringsratt 19, et utlop 21 for den pressede masse som befinner seg i den ytre kappe 17 bak spjellet l8, et nedre væske-oppsamlings-trau 22 som er forsynt med et utlop 23 for væsken, og drivorganer for omdreining av skruespindelen og omfattende en motor 24 og en girkasse 25, i hvilken motorens hastighet reduseres. The main or final press 2 which is fed by the pre-press 1 and is also connected to the liquid collection trough 6 by means of a rudder 13, comprises a single screw spindle 14 which preferably has an approximately parabolic contour and is provided with screw threads or wings 14, a perforated screen jacket 16, which has a circular cross-section along its entire length and is preferably cylindrical, a plurality of retaining or counter-holding members 20, which are located in the gap between the screw spindle 14 and the screen mantle 16, an outer casing which surrounds the screw spindle 14 and is spaced from this, a rotary valve or rotary damper l8 preferably of the rosette type and provided with a control wheel 19, an outlet 21 for the pressed mass located in the outer jacket 17 behind the damper l8, a lower liquid collection trough 22 which is provided with an outlet 23 for the liquid, and drive means for turning the screw spindle and comprising a motor 24 and a gearbox 25, in which the speed of the motor is reduced.
Den forkomprimerte masse fra den vertikale forpresse 1 innfores i den horisontale sluttpresse 2 i kloften mellom dennes skruespindel 14 og silmantel 16 ved sluttpressens 2 innlopsende ( den venstre ende på fig. 1 og 2). I fig. 2 bor det observeres at de nedre ender av forpressens skruespindler befinner seg på siden av sluttpressens skruespindels aksel og er forskutt i forhold til hverandre i en retning som er hovedsakelig parallelle med sluttpressens skruespindels aksel. Dette sikrer optimal matning av sluttpressen. I sluttpressen 2 sammenpresses massen ytterligere og avvannes samt fremmates også av skruespindelen 14 og dennes vinger 15. Motholdsorganer 2o som fortrinnsvis er anordnet jevnt fordelt og av hvilke bare et fåtall er vist i fig. 2, har til oppgave å omrore massen og hindre denne fra å rotere under dens bevegelse langs skruespindelen 14, The pre-compressed mass from the vertical pre-press 1 is fed into the horizontal final press 2 in the gap between its screw spindle 14 and sieve jacket 16 at the inlet end of the final press 2 (the left end of fig. 1 and 2). In fig. 2 it should be observed that the lower ends of the prepress screw spindles are located on the side of the final press screw spindle shaft and are offset relative to each other in a direction that is essentially parallel to the final press screw spindle axis. This ensures optimal feeding of the final press. In the final press 2, the mass is further compressed and dewatered as well as fed forward by the screw spindle 14 and its wings 15. Counterholding members 2o which are preferably arranged evenly distributed and of which only a few are shown in fig. 2, has the task of stirring the mass and preventing it from rotating during its movement along the screw spindle 14,
for herved å sikre mest mulig effektiv sammenpressing og avvanning av massen. thereby ensuring the most efficient compression and dewatering of the mass.
Den væske som utpresses fra massen gjennom silmantelen The liquid that is squeezed out of the mass through the sieve jacket
l6 oppsamles i det nedre trau 22, i hvilket tilkoplingsroret 13 fra forpressens 1 trau 6 munner ut, og væskeblandingen fra de to presse-deler avledes deretter gjennom utlopet 23. l6 is collected in the lower trough 22, into which the connecting pipe 13 from the prepress 1 trough 6 exits, and the liquid mixture from the two press parts is then diverted through the outlet 23.
På grunn av at silmantelen 16 har rundt tverrsnitt er den meget robust og bibeholder derfor sin form under en lang virksom arbeidsrid. En noyaktig passing mellom vingenes 15 kanter og silmantelen l6 opprettholdes således, og pressen gir et hoyt presse-trykk og således en hoy kapasitet under hele sin levetid. Due to the fact that the sieve jacket 16 has a round cross-section, it is very robust and therefore retains its shape during a long active working cycle. A precise fit between the edges of the wings 15 and the sieve jacket l6 is thus maintained, and the press provides a high pressing pressure and thus a high capacity during its entire lifetime.
Skruespindlenes 4 og 5 kanter likesom kantene av skrue-spindelens 14 vinger 15 er herdet eller på annen måte forsterket. Skruespindlenes 4 og 5 ytre deler likesom de ytre deler av vingene 15 og skruespindelen 14 er overtrukne, f.eks. ved sproytning med rustfritt stål. Alle disse deler er således motstandskraftige mot både erosjon og korrosjon, hvilket også i denne henseende sikrer en lang levetid av pressen uten reparasjoner. The edges of the screw spindles 4 and 5, as well as the edges of the wings 15 of the screw spindle 14, are hardened or reinforced in some other way. The outer parts of the screw spindles 4 and 5, as well as the outer parts of the wings 15 and the screw spindle 14, are coated, e.g. by spraying with stainless steel. All these parts are thus resistant to both erosion and corrosion, which also in this respect ensures a long service life of the press without repairs.
Pressens totale silflate kan være av størrelsesordenen Trykket av massen i pressen reguleres av dreiespjellet l8, som fortrinnsvis er av rosett-typen, og som tydelig vist i fig. 15 består av en fast og en bevegelig ringformet styrelist 27 resp.28 som er forsynt med hull eller spalter 29. Spjellets dreibare styrelist 27 reguleres ved hjelp av rattet 19 på en slik måte, at kloft-åpningen for massen og således dennes trykk reguleres. Med denne utformning av spjellet kan et hoyt trykk oppnås i pressen, og dette sikrer forbedret avrenning av pressevann og en hoy torrgehalt av den pressede masse. The total screen surface of the press can be of the order of magnitude The pressure of the mass in the press is regulated by the rotary damper l8, which is preferably of the rosette type, and as clearly shown in fig. 15 consists of a fixed and a movable ring-shaped guide bar 27 or 28 which is provided with holes or slits 29. The damper's rotatable guide bar 27 is regulated by means of the steering wheel 19 in such a way that the gap opening for the mass and thus its pressure is regulated. With this design of the damper, a high pressure can be achieved in the press, and this ensures improved drainage of press water and a high dry content of the pressed pulp.
Den ferdigpressede' masse forlater pressen gjennom utlopet 21. The 'ready-pressed' mass leaves the press through the outlet 21.
Utforelsesformen i henhold til fig. 4 til fig.7, i hvilke de samme henvisningstall som i fig. 1 til fig. 3 er blitt anvendt for å betegne samme eller analoge deler, er i prinsippet lik den ovenfor beskrevne utforelsesform og skal derfor bare beskrives i den utstrekning som den avviker derfra. The embodiment according to fig. 4 to fig. 7, in which the same reference numbers as in fig. 1 to fig. 3 has been used to denote the same or analogous parts, is in principle similar to the embodiment described above and should therefore only be described to the extent that it deviates from it.
I henhold til fig. 4-7 er forpressen 1 ikke vertikal slik som i utforelsesformen i henhold til fig.l-3, men horisontal, slik som sluttpressen 2. Dette medforer naturligvis storre behov med hensyn til markflate, men lavere bygningshoyde. According to fig. 4-7, the pre-press 1 is not vertical as in the embodiment according to fig.l-3, but horizontal, like the final press 2. This naturally entails greater needs with regard to land area, but lower building height.
I fig. 6 og 7 Dor spesielt legges merke til at de perforerte silmantlers 7 °g l6 tverrsnitt noyaktig slutter seg til den ytre kontur av skruespindlene 4 °g 5 resp. 14 inklusive disses vinger. In fig. 6 and 7 Dor in particular it is noticed that the cross-section of the perforated screen mantles 7 °g l6 exactly joins the outer contour of the screw spindles 4 °g 5 resp. 14 including their wings.
Utforelsesformen i henhold til fig. 8-I0 kan sies å være det omvendte av den utforelsesform som er vist i fig. 1~3> eftersom forpressen 1 er horisontal og sluttpressen 2 er vertikal. Denne ut- The embodiment according to fig. 8-10 can be said to be the reverse of the embodiment shown in fig. 1~3> since the prepress 1 is horizontal and the final press 2 is vertical. This out-
forelsesform krever en betydelig byggehoyde, men en begrenset markflate. form of construction requires a significant building height, but a limited land area.
Fig. 11 til 13 anskueliggjor en utforelsesform i hvilken Fig. 11 to 13 illustrate an embodiment in which
en forpresse 1, som omfatter to i hverandre inngripende skruespindler 4 og 5) mater to separate sluttpresser som hver har individuelle skrue- a pre-press 1, which comprises two interlocking screw spindles 4 and 5) feeds two separate final presses, each of which has individual screw-
spindler 14 med vinger 15, silmantler 16 og ytre kapper 17. Også i denne utforelsesform omgir silmantlene 7 °g 16 tett sine skruespindler 4 og 5 resp. 14 med et ubetydelig spillerom mellom skruespindlenes vinger og de respektive perforert silmantler. Ved denne utforelses- spindles 14 with wings 15, screen mantles 16 and outer covers 17. Also in this embodiment, the screen mantles 7 °g 16 closely surround their screw spindles 4 and 5 resp. 14 with a negligible clearance between the wings of the screw spindles and the respective perforated screen mantles. In this embodiment
form har alle skruespindlene en felles drivmotor 24 og en felles hastighetsreduserende girkasse 25» Da skruespindlene 14 åpenbart roterer i motsatt retning, har de i motsatt retning rettede vinger 15. Det er også mulig å anordne tre i hverandre inngripende skrue- form, all the screw spindles have a common drive motor 24 and a common speed-reducing gearbox 25". As the screw spindles 14 obviously rotate in the opposite direction, they have wings 15 directed in the opposite direction. It is also possible to arrange three interlocking screw-
spindler 4>5°g 45 innenfor en felles silmantel 7» som inngår i for- spindles 4>5°g 45 within a common sieve mantle 7" which is part of the
pressen 1, slik som anskueliggjort i fig. 14, som skiller seg fra den venstre del av fig. 2 bare i denne henseende. the press 1, as illustrated in fig. 14, which differs from the left part of fig. 2 only in this respect.
I fig. 14 bor det spesielt observeres at silmantelenes In fig. 14 it should be particularly observed that the sieve mantles
tverrsnitt noyaktig slutter seg til ytterkonturene av skruespindlene 4,5 °g 45- Denne likedannethet mellom ytterkonturene av skrue- cross-section exactly joins the outer contours of the screw spindles 4.5 °g 45- This similarity between the outer contours of the screw-
spindlene inklusive deres vinger, og den perforerte silmantels tverr- the spindles including their wings, and the perforated sieve mantle cross-
snitt, uavhengig av dennes form, kan opprettholdes bare takket være det begrensede overtrykk som hersker i forpressen og som holdes innen- section, regardless of its shape, can be maintained only thanks to the limited overpressure that prevails in the prepress and is kept within
for moderate grenser (1-1,5 kg/cm ), beroende på at hele pressen er oppdelt i en forpresse og en sluttpresse. for moderate limits (1-1.5 kg/cm ), depending on the entire press being divided into a pre-press and a final press.
De ovenfor beskrevne og på tegningene anskueliggjorte utforelsesformer er bare å betrakte som ikke-begrensendé eksempler og kan med hensyn til sine detaljer modifiseres på flere måter innen rammen for de etterfølgende krav.
