Description

Fremgangsmåte og anordning til å drive et endeløst filterbånd. Method and device for driving an endless filter belt.

Denne oppfinnelse vedrører en fremgangsmåte og en anordning for drift av et endeløst filterbånd, hvilket for rensning og olj ing passerer gjennom et olje- eller væskebad. This invention relates to a method and a device for operating an endless filter belt, which for cleaning and oiling passes through an oil or liquid bath.

Ved slike såkalte oljefibre fremmates In such cases, so-called oil fibers are produced

filterbåndet (filterbåndene) enten kontinuerlig med liten hastighet eller skrittvis ved intermitente fremmatningsbevegelser. I begge tilfelle passerer båndet oljebadet i en og samme bevegelsesretning og forholds-vis langsomt, hvilket medfører dels at bån-dets rensning og olj ing blir ufullstendig og dels at olje i dråpeform følger med båndet og senere rykkes med av den passerende luftstrøm. Foreliggende oppfinnelse går ut på en enkel og effektiv måte til å avhjelpe disse mangler. the filter belt(s) either continuously at low speed or step by step with intermittent feed movements. In both cases, the belt passes the oil bath in one and the same direction of movement and relatively slowly, which means that the cleaning and oiling of the belt is incomplete and that oil in droplet form follows the belt and is later carried along by the passing air flow. The present invention provides a simple and effective way to remedy these deficiencies.

Oppfinnelsen utmerker seg ved at filterbåndets fremmatning skjer ved at dette bibringes en frem- og tilbake-gående bevegelse, idet bevegelsesfasene gis forskjellig lengde, resulterende i en bestemt fremmatningsretning. The invention is distinguished by the fact that the feeding of the filter belt takes place by imparting a reciprocating movement, the movement phases being given different lengths, resulting in a specific feeding direction.

Denne måte til fremmatning av filterbåndet fører til en økning av filterelemen-tets relative bevegelseshastighet vis a vis oljebadet og den gjentatte reversering av bevegelsesretningen fører til at oljen om-røres og bringes til effektivt å gjennom - skylle og rense filterelementene. Samtidig vil overflødig olje i form av større, frie oljedråper på de fra oljebadet oppgående fil-terelementer rystes av før elementene kom-mer i stilling til å gjennomstrømmes av det medium som skal filtreres. Ved fremgangs-måten ifølge oppfinnelsen kan man således oppnå en mere effektiv rensning av filterbåndet uten risiko for at det gjennom-strømmende medium forurenses av med-revne oljedråper. Filterbåndet kan da drives kontinuerlig, men mere hensiktsmessig er det å drive det intermitterende under tilbakekommende perioder med bestemte intervaller. This way of feeding the filter belt leads to an increase in the filter element's relative movement speed vis-à-vis the oil bath and the repeated reversal of the direction of movement causes the oil to be stirred and brought to effectively rinse and clean the filter elements. At the same time, excess oil in the form of larger, free oil droplets on the filter elements rising from the oil bath will be shaken off before the elements are in a position to flow through the medium to be filtered. With the method according to the invention, a more effective cleaning of the filter belt can thus be achieved without the risk of the medium flowing through being contaminated by entrained oil droplets. The filter belt can then be operated continuously, but it is more appropriate to operate it intermittently during recurring periods at specific intervals.

Ved en endring av oppfinnelsen kan filterbåndets rengjøring ytterligere forbe-dres ved at filterbåndet bringes til i oljebadet å vende om en av radikalt utskyt-ende flenser dannet aksel, hvorved oljebadet omrøres og tvinges til å sirkulere gjennom filterbåndet. In a change to the invention, the cleaning of the filter belt can be further improved by causing the filter belt to turn in the oil bath about an axle formed by radically projecting flanges, whereby the oil bath is stirred and forced to circulate through the filter belt.

En hensiktsmessig utførelsesform av en anordning for fremgangsmåtens utfø-relse består av en mellom drivmotoren og filterbåndets drivaksel anordnet fremmatningsmekanisme bestående av et nav, hvilket bibringes en frem- og tilbakegående dreiebevegelse ved en av drivmotorens aksel drevet veivstangforbindelse og hvilket nav bærer to sperrer, hvilke vekselvis med-bringer resp. frigjøres fra en filterbåndene drevet skive, hvilke sperrer er således anordnet på og styrt av navet at dettes dreie-bevegelser i den ene retning helt over-føres til drivskiven, mens derimot navet ved sin bevegelse i den andre retning bibringer drivskiven en mindre vinkelforandring enn hva der svarer til navets egen bevegelse, resulterende i en bestemt fremmatningsretning. An appropriate embodiment of a device for carrying out the method consists of a feed mechanism arranged between the drive motor and the filter belt's drive shaft consisting of a hub, which is imparted with a reciprocating turning movement by a crankshaft connection driven by the drive motor's shaft and which hub carries two detents, which alternately with-bringer or is released from a disk driven by the filter bands, which detents are arranged on and controlled by the hub in such a way that its turning movements in one direction are completely transferred to the drive disk, while on the other hand the hub, by its movement in the other direction, causes the drive disk a smaller angular change than what which corresponds to the hub's own movement, resulting in a specific feed direction.

Oppfinnelsen skal nu nærmere forkla-res i tilslutning til tegningene, hvilke viser et utførelseseksempel. Fig. 1 viser et oljefilter sett delvis fra siden og delvis (under linjen II—II) i snitt. Fig. 2 viser en detalj i større målestokk av drivanordningen for filterbåndene. The invention will now be explained in more detail in connection with the drawings, which show an exemplary embodiment. Fig. 1 shows an oil filter seen partly from the side and partly (below the line II—II) in section. Fig. 2 shows a detail on a larger scale of the drive device for the filter belts.

Om navet 14 fra den i figuren viste stilling tenkes å bevege seg mot urviseren, presser navet ved tappen 16 34 with the center of the arc radii in the pivot centers of the rafters 17 resp. 32. If the hub 14 from the position shown in the figure is thought to move clockwise, the hub presses against the pin 16

Sperren 29 deltar i navets bevegelse som overfører gjennom sin stilling og sin form ingen fremdrivende the latch 15 against the drive disc 22, which is thereby included in the movement. The stopper 29 participates in the movement of the hub which, through its position and shape, transmits no driving force
