Description
Trommelpresse eller anordning for utpressing av væske av cellulose og annen fibermasse som er oppslammet i vann eller oppløsninger inneholdende kjemikalier som benyttes ved fremstilling eller foredling av vedkommende fibermasse. Drum press or device for squeezing out liquid from cellulose and other fiber pulp that has been suspended in water or solutions containing chemicals that are used in the production or processing of the fiber pulp in question.

Anordningen består av et like antall The device consists of an equal number

lene dannes et sentralt rom hvis sideflater består av 4 trommelkvadranter hvis endeflater dekkes av to stillestående tett-ningsplater som holdes trykket mot tromlens endeflater. Massen tilføres nevnte rom under trykk gjennom en av disse tetningsplater. Ved dette arrangement får lene, a central space is formed whose side surfaces consist of 4 drum quadrants whose end surfaces are covered by two stationary sealing plates which are kept pressed against the end surfaces of the drum. The mass is supplied to said room under pressure through one of these sealing plates. At this event,
man to pressesteder beliggende diame-tralt overfor hverandre. Massen som av-setter seg på silplatene blir ført kontinu-erlig sammen med denne ut gjennom pres-sestedene. To av tromlene kan være fast lagret og to tromler ettergivende opplagret. De sistnevnte holdes da trykket mot one two press points located diametrically opposite each other. The mass that settles on the sieve plates is led continuously together with it out through the pressing points. Two of the drums can be fixedly stored and two drums resiliently stored. The latter are then held pressed against
de fast lagrede ved hjelp av hydrauliske trykksylindre. the fixed stored by means of hydraulic pressure cylinders.
Det hydrauliske pressesystem er utført på en sådan måte at lagertrykket automatisk avpasses etter massetrykket i det sentrale rom og at dessuten den bevegelige trommels akse søker å innstille seg paral-lelt med aksen til den fast lagrede trommel. Drivanordningen kan utføres således at drivakslene for de enkelte tromler dri-ves av tannhjul med tilnærmelsesvis samme delesirkeldiameter som tromlenes dia-meter og at tannhjulet for den enkelte trommel står i inngrep med tannhjulene for de to sidetromler. The hydraulic press system is designed in such a way that the bearing pressure is automatically adapted to the mass pressure in the central space and that, moreover, the axis of the movable drum seeks to align itself parallel to the axis of the fixed drum. The drive arrangement can be designed so that the drive shafts for the individual drums are driven by gears with approximately the same pitch circle diameter as the diameter of the drums and that the gear for the individual drum engages with the gears for the two side drums.
Fig. 1 og 2 viser en utførelse av maskinen hvor trommelaksen er anordnet verti-kalt. Denne anordning er antagelig den Fig. 1 and 2 show an embodiment of the machine where the drum axis is arranged vertically. This device is presumably the one
mest rasjonelle, men det er også mulig å bygge maskinen med trommelaksene lig-gende horisontalt. most rational, but it is also possible to build the machine with the drum axes lying horizontally.
Fig. 1 viser maskinen sett ovenfra. 1— 2 — 3 og 4 er de fire sil-tromler. Trommel Fig. 1 shows the machine seen from above. 1— 2 — 3 and 4 are the four sieve drums. Drum
1 beveger seg motsatt urviseren ogj I er fast opplagret. Trommel 2 beveger seg med urviseren og er bevegelig opplagret. Mellom disse to tromler får man et pressested hvor massen under trykk føres ut' av det sentrale rom 5. Trommel 4 er fast lagret, og mellom trommel 2 og 4 har mari en ganske liten spalt. Silflåtene beveger | seg her inn mot det sentrale rom 5. Trommel 3 er bevegelig opplagret, og mellom trommel 3 og 4 har man et nytt pressested hvor massen føres ut fra det sentrale rom |5. 6 og 7 (fig. 2) er de to tetningsplater som tetter mot tromlenes endeflater. Disse (tetningsplater kan ved hjelp av en felles<1> hydraulisk sylinder 10 holdes trykket |mot tromlene, hvorved man unngår at trykket overføres på tromlenes bærelagre. j 1 moves counter-clockwise and j I is fixed. Drum 2 moves clockwise and is movably supported. Between these two drums, you get a pressing point where the mass under pressure is led out of the central chamber 5. Drum 4 is fixedly stored, and between drums 2 and 4 there is a fairly small gap. The sieve rafts move | here towards the central room 5. Drum 3 is movably stored, and between drums 3 and 4 there is a new pressing point where the mass is fed out from the central room |5. 6 and 7 (fig. 2) are the two sealing plates that seal against the end surfaces of the drums. These (sealing plates) can be kept pressed against the drums by means of a common<1> hydraulic cylinder 10, thereby avoiding that the pressure is transferred to the drums' bearing bearings. j
Fig. 2 viser maskinen i oppriss. Massen pumpes inn gjennom røret 8 anordnet i tetningsplaten 6, (den kan også om ønskes tilføres nedenfra gjennom tetningsplaten 7). Den utpressede væske passerer gjennom silplaten og inn i de respektive tromler og kan skaffes avløp gjennom trommeltappen. 9 viser driftsanordningen som kan bestå av motor med gear som dri-ver et av de fire sammenkoblede tannhjul som hver for seg overfører bevegel-sen til hver enkelt trommel gjennom bevegelige koblinger og mellomaksler. J Fig. 2 shows the machine in elevation. The mass is pumped in through the pipe 8 arranged in the sealing plate 6, (it can also be supplied from below through the sealing plate 7 if desired). The squeezed liquid passes through the sieve plate and into the respective drums and can be drained through the drum tap. 9 shows the operating device, which may consist of a motor with a gear that drives one of the four interconnected gears which individually transmit the movement to each individual drum through movable couplings and intermediate shafts. J
Det hydrauliske system for belastning av lagerne på trommel 2 og 3 kan arran-geres således at lagertrykket avpasses etter massetrykket i det sentrale rom 5.' Det samme gjelder trykket i den trykksyjlinder som holder tetningsplatene 6 og 7 presset mot tromlens endeflater. Lagernes trykksylindre er sammenkoblet på en sådan må-te at den bevegelige trommelakse j alltid forblir parallell med aksen til den fast lagrede trommel. j The hydraulic system for loading the bearings on drums 2 and 3 can be arranged so that the bearing pressure is adapted to the mass pressure in the central chamber 5. The same applies to the pressure in the pressure cylinder which keeps the sealing plates 6 and 7 pressed against the end surfaces of the drum. The pressure cylinders of the bearings are interconnected in such a way that the movable drum axis j always remains parallel to the axis of the fixed drum. j
Hvis man anvender 6 tromler anord-nes disses akser i hjørnene av en regulær sekskant, og massen går ut fra det sentrale rom på tre steder, i en vinkelavstand av 120° fra hinannen. | If 6 drums are used, their axes are arranged in the corners of a regular hexagon, and the mass exits from the central space in three places, at an angular distance of 120° from each other. |
Man kan også tenke seg utførelser hvor tetningsplatene ikke er heltj stillestående, men får en eller annen bevegelse. Istedetfor å la platene være avtettet mot tromlene kan de dessuten anbringes i en liten avstand fra tromlenes endeflater, ca 1 mm. i One can also imagine designs where the sealing plates are not completely stationary, but get some movement. Instead of leaving the plates sealed against the drums, they can also be placed at a small distance from the end surfaces of the drums, approx. 1 mm. in
Man vil derved unngå en vesentlig del av friksjonsmotstanden mellom tromlenes endeflater og tetningsplatene, og den tyk-ke masse som innføres i det sentrale rom, utgjør da selv det nødvendige tetningsma-teriale. One will thereby avoid a significant part of the frictional resistance between the end surfaces of the drums and the sealing plates, and the thick mass that is introduced into the central space then itself constitutes the necessary sealing material.
Videre kan der tenkes utførelser hvor f. eks. alle 4 sylindere er bevegelig opplagret, eller man kan anordne alle 4 sylindere med fast opplagring. I sistnevnte tilfelle må sylindrene monteres med en passende spalteåpning der hvor den pressede masse kommer ut, samtidig med at man regule-rer utpressingsgraden ved å variere val-senes omdreiningstall. Furthermore, designs can be thought of where, e.g. all 4 cylinders are movable, or you can arrange all 4 cylinders with fixed storage. In the latter case, the cylinders must be fitted with a suitable slit opening where the pressed mass comes out, while at the same time regulating the degree of extrusion by varying the revolutions of the rollers.
