Description

Oppfinnelsen angår en anordning for destruksjon av papir og kartong, omfattende et kar åpent på oversiden som mates med råmateriale som skal destrueres, f.eks. fra en papirmaskin beliggende ovenfor, og fjernes destruert derfra ved hjelp av en pumpe, og minst to destruksjonsenheter, fortrinnsvis roterende rotorer, festet ved karets ene vegg. En lignende anordning anvendes under store papirmaskiner for destruksjon av papir eller kartong som har blitt til overs, f.eks. som tilskjæringsrester. Ovenfor anordningen er det utført styreorganer utformet som renner, som styrer papiret og kartongen som skal destrueres fra papirmaskinen til det åpne karet på oversiden. På karets ene side er det anbragt destruksjonsenheter som.utgjøres av rotorer. I de fleste til-feller er rotorene to i antall og de har begge sin egen driv-motor. Rotorene er nå for tiden anbragt ved siden av hverandre i samme høyde fra karets bunn, og deres aksler er parallelle. Derved er den vegg av karet hvor rotorene er anbragt rett i det minste sett ovenfra. På utsiden av karet, mellom rotorakslene, er det vanligvis anbragt en utløpspumpe for den destruerte masse. The invention relates to a device for the destruction of paper and cardboard, comprising a vessel open on the upper side which is fed with raw material to be destroyed, e.g. from a paper machine located above, and is removed destroyed from there by means of a pump, and at least two destruction units, preferably rotating rotors, attached to one wall of the vessel. A similar device is used under large paper machines for the destruction of paper or cardboard that has been left over, e.g. as trimmings. Above the device, there are control elements designed as chutes, which guide the paper and cardboard to be destroyed from the paper machine to the open vessel on the upper side. On one side of the vessel there are destruction units which are made up of rotors. In most cases, the rotors are two in number and they both have their own drive motor. The rotors are currently placed next to each other at the same height from the bottom of the vessel, and their axes are parallel. Thereby, the wall of the vessel where the rotors are placed is straight at least when viewed from above. On the outside of the vessel, between the rotor shafts, there is usually an outlet pump for the destroyed mass.

Teknikken idag er imidlertid beheftet med flere ulemper, av hvilke en er den at destruktorene under brede papir-og kartongmaskiner selv er brede, slik at utnyttelsen av strømningen ved destruksjonen av papir eller kartong ikke er tilstrekkelig effektiv, men krever mye energi for at et bra destruksjonsresultat skal oppnås. Videre er rommet mellom rotorenes drivaksler meget lite, slik at bare et be-skjedent rom står til disposisjon for den destruerte masses utløpspumpe. Da bredden av de nåværende rettveggede destruk-tører vokser, blir kartongdestrueringen dyr, da rotorene som anbringes ved den rette veggen krever et mangfold av støtte-konstruksjoner, da karet ikke er stivt i seg selv. However, today's technology is fraught with several disadvantages, one of which is that the destructors under wide paper and cardboard machines are themselves wide, so that the utilization of the flow during the destruction of paper or cardboard is not sufficiently efficient, but requires a lot of energy for a good destruction result must be achieved. Furthermore, the space between the drive shafts of the rotors is very small, so that only a limited space is available for the discharge pump of the destroyed mass. As the width of the current straight-walled destructors increases, cardboard destruction becomes expensive, as the rotors placed at the straight wall require a variety of support structures, as the tub is not rigid in itself.

Formålet med oppfinnelsen er å tilveiebringe en anordning for destruksjon av papir og kartong, som ikke har de ovenfor nevnte ulemper og som således er mer fordelaktig å fremstille og strømningsteknisk bedre utformet enn de nåværende kjente anordninger. Det karakteristiske ved anordningen ifølge oppfinnelsen er at de rette linjer som går via rotorenes akselinjer skjærer hverandre i det minste i en projeksjon. The purpose of the invention is to provide a device for the destruction of paper and cardboard, which does not have the above-mentioned disadvantages and which is thus more advantageous to manufacture and flow-technically better designed than the currently known devices. The characteristic feature of the device according to the invention is that the straight lines that run via the axis lines of the rotors intersect at least in one projection.

Som de største fordeler kan nevnes konstruksjonens stivhet og tilleggsrommet som oppnås mellom akslener for masse-pumpen. Oppfinnelsen skal beskrives nærmere i det ffølgende i forbindelse med et utførelseseksempel og under henvisning til tegningene, der fig. 1 er et sideriss delvis i-snitt etter linjen I-l på fig. 4 av en anordning ifølge oppfinnelsen for destruksjon av papir og kartong, fig. 2 er:et riss av anordningen på fig. 1 sett fra venstre, fig. 3 er. et plan-riss av en anordning fra kjent teknikk, og fig. 4 er et plan-riss av anordningen ifølge oppfinnelsen. The biggest advantages can be mentioned the rigidity of the construction and the additional space that is achieved between the axles for the pulp pump. The invention shall be described in more detail below in connection with an exemplary embodiment and with reference to the drawings, where fig. 1 is a side view partially in section along the line I-1 in fig. 4 of a device according to the invention for the destruction of paper and cardboard, fig. 2 is a view of the device in fig. 1 seen from the left, fig. 3 is. a plan view of a device from prior art, and fig. 4 is a plan view of the device according to the invention.

På fig. 1 er det vist en anordning ifølge?oppfinnelsen for destruksjon av papir og kartong. Anordningen er fortrinnsvis anbragt under en stor papirmaskin, hvor innmatnin-gen til karet 1 av materiale som skal destrueres sk'-g~er via karets åpne overdel. Ovenfor karet er det for detten formål utformet styreorgan 2 på skrå. In fig. 1 shows a device according to the invention for the destruction of paper and cardboard. The device is preferably placed under a large paper machine, where material to be destroyed is fed into the vessel 1 via the vessel's open upper part. Above the tub, for this purpose, a guide member 2 is designed at an angle.

Destruksjonen av papir og kartong i karet; 1 skjer The destruction of paper and cardboard in the tub; 1 happens

med destruksjonsenhetene 3, som fortrinnsvis utgjøres av roterende rotorer. I dette utførelseseksempel finnes to rotorer og de befinner seg i samme høyde og i samme vegg av karet 1. Rotorenes 3 drivmotorer 4 er anbragt ute ved rotorenes aksler utenfor karet. with the destruction units 3, which preferably consist of rotating rotors. In this design example, there are two rotors and they are located at the same height and in the same wall of the vessel 1. The rotors' 3 drive motors 4 are located outside the rotors' shafts outside the vessel.

På fig. 2 er det vist en anordning ifølge fig. 1 In fig. 2 shows a device according to fig. 1

sett fra siden. Det vises at det mellom drivmotorenes og rotorenes aksler ved karets vegg er tilkoblet et utløpsrør 5 for destruert masse. Dette er tilsluttet en masseutløpspumpe som ikke er vist på figurene, men som fortrinnsvis er plas-sert mellom nevnte aksler. seen from the side. It is shown that an outlet pipe 5 for destroyed mass is connected between the shafts of the drive motors and the rotors at the wall of the vessel. This is connected to a mass discharge pump which is not shown in the figures, but which is preferably placed between said axles.

På fig. 3 er det vist en kjent destruktør sett ovenfra. Der er rotorenes aksler 3 parallelle. Derved er også veggen 6 i karet 1 rett. På fig. 4 er det derimot vist en anordning ifølge oppfinnelsen sett ovenfra. Som det frem-går skjærer rotorenes 3 forlengelser hverandre. Veggen 6 er bøyd slik at karets 1 bredeste sted er ved midten av denne. In fig. 3 shows a known destructor seen from above. There, the rotors' axes 3 are parallel. Thereby, the wall 6 in the tub 1 is also straight. In fig. 4, on the other hand, shows a device according to the invention viewed from above. As can be seen, the 3 extensions of the rotors intersect. The wall 6 is bent so that the vessel 1's widest point is at the middle of it.

For en fagmann på området er det klart at oppfin-nelsens forskjellige tilpasningsformer ikke er begrenset til de ovenfor viste eksempler, men at de kan variere innenfor rammen av det etterfølgende krav. For a person skilled in the field, it is clear that the various adaptations of the invention are not limited to the examples shown above, but that they can vary within the scope of the following claim.
