Description
Oppfinnelsen vedrører aggregater til utsugning av røkgasser fra arbeidsplasser hvor det dannes helsefarlige gasser, hvor aggregatet består av en utsugningsvifte og et sugehode samt minst en mellom utsugningsviften og sugehodet forløpende, bøyelig slange. The invention relates to aggregates for extracting flue gases from workplaces where gases hazardous to health are formed, where the aggregate consists of an extraction fan and a suction head as well as at least one continuous, flexible hose between the extraction fan and the suction head.
I de tilfeller hvor kjente utsugningsaggregater av denne In those cases where known extraction units of this
art overhodet gjør det mulig å innstille sugehodet i forhold til arbeidsplassen, er det tale om konstruksjoner hvor den bøyelige slange holdes hengende ved siden av eller under en bæreanordning. Som følge av dette blir utsugningsaggregatet komplisert og vanskel.!._: å håndtere, og dessuten huker bæreorganet og/eller slangen seg lett fast i gjenstander på arbeidsplassen når aggregatet omstilles. For-målet med oppfinnelsen er å fjerne disse ulemper og å fremskaffe et utsugningsaggregat som har en funksjonelt tilsiktet riktig utforming og som ikke har utadragende deler som kan huke seg fast i verktøy og andre gjenstander på arbeidsplassen ved omstilling av aggregatet. art at all makes it possible to adjust the suction head in relation to the workplace, these are constructions where the flexible hose is kept hanging next to or under a carrying device. As a result, the extraction unit becomes complicated and difficult to handle, and furthermore the support member and/or hose easily snags on objects at the workplace when the unit is repositioned. The purpose of the invention is to remove these disadvantages and to provide an extraction unit which has a functionally intended correct design and which does not have protruding parts that can get caught in tools and other objects at the workplace when the unit is changed.
Dette oppnås ifølge oppfinnelsen ved at utsugningsaggregatets bærearmer er anbrakt inne i den bøyelige slange. According to the invention, this is achieved by the extraction unit's support arms being placed inside the flexible hose.
For å fremskaffe en stabil og funksjonssikker enhet som kan svinges vesentlig bort fra arbeidsplassen når den ikke anvendes, In order to provide a stable and functionally reliable unit that can be swung significantly away from the workplace when not in use,
er den ene arm i sin ene ende, for dreining i et vertikalt plan, leddbart forbundet med et rørbend som er dreibart lagret på viftens mantel og som er dreibart i horisontalplanet og ved sin annen ende er den leddbart forbundet med den annen arm som er bevegelig i samme vertikale plan som den første arm. one arm is at its one end, for turning in a vertical plane, articulatedly connected to a pipe bend which is rotatably stored on the fan's casing and which is rotatable in the horizontal plane and at its other end it is articulatedly connected to the other arm which is movable in the same vertical plane as the first arm.
De leddbare armers leddforbindelser kan bestå av et friksjonsledd, hvor friksjonen er valgt således at sugehodet fastholdes i den innstilte stilling. The joint connections of the articulated arms can consist of a friction joint, where the friction is chosen so that the suction head is maintained in the set position.
For å avlaste friksjonsleddene er der anbrakt minst to strekkfjærer hvorav den ene er innspent mellom et punkt på rørbendet i nærheten av det første ledd og den annen f jaer er innspent mellom et punkt i nærheten av det annet ledd og et punkt på den annen arm i nærheten av dens ende som bærer sugehodet. In order to relieve the friction joints, at least two tension springs are placed, one of which is clamped between a point on the pipe leg near the first joint and the other spring is clamped between a point near the second joint and a point on the other arm in near its end which carries the suction head.
For at også sugehodet skal kunne holdes fast i ønsket stilling er det forbundet med den annen arm ved hjelp av et friksjonsledd. Denne utforming medfører at det blir god plass i sugehodet til opp-takelse av et spjeld som er innstillet til å regulere størrelsen på sugehodets inntaksåpning. So that the suction head can also be held firmly in the desired position, it is connected to the other arm by means of a friction joint. This design means that there is plenty of space in the suction head for accommodating a damper which is set to regulate the size of the suction head's intake opening.
Videre skal den bøyelige slange for å kunne være holdbar og Furthermore, the flexible hose must be durable and
varmebestandig fremstilles av varmebestandig, glassfiberarmert plast. heat-resistant is produced from heat-resistant, glass-fibre reinforced plastic.
Aggregatet ifølge oppfinnelsen vil fremgå i detalj av det ut-førelseseksempel som skal beskrives i det etterfølgende under hen-visning til tegningene, hvori: Fig. 1 viser et aggregat ifølge oppfinnelsen sett fra siden The unit according to the invention will appear in detail from the design example to be described in the following with reference to the drawings, in which: Fig. 1 shows a unit according to the invention seen from the side

Fig. 4 viser i større målestokk forskjellige detaljer ved Fig. 4 shows on a larger scale various details of
aggregatet. the aggregate.
I fig. 1 er vist en utsugningsvifte 1, med et sugehode 2 og en slange 3 som løper mellom viften og sugehodet. Viften består av en motor 4 som driver viftehjulet (ikke vist) samt en vifte-mantel 5. Fra viftemantelen løper det utad et sentralt rør 6, på hvilket det er dreibart anordnet et rørbend 7. På rørbendets 7 frie ende er det festet en eller flere plater 8, som på sin side utgjør lagring for såvel en første svingbar arm 9 som en eller f iere strekkf jærer 10, som bare er vist skjematisk med strekpunkt-linjer i fig. 1. På den fra viften vendte ende av den første svingbare arm 9 er fastsveiset en stort sett trekantet plate 11, som ut-gjør feste for en andre svingbar arm 12 samt en eller flere ytter-ligere strekkfjærer 13. Fjærens 13 andre ende er festet til en knast 14 som rager utad fra armen 12 og som ligger nær armens 12 ytre ende. Ved armens 12 ytre ende er sugehodet 2 svingbart festet ved 15. Sugehodet er utstyrt med et håndtak 16 og et spjeld 17 som er vist med strekete linjer. Sugehodet 2 er svingbart i forhold til armen 12 i en'retning som vises ved pilen 18. Den bøyelige slange 3 som fortrinnsvis er av glassfiberarmert varmebestandig plast, er tredd utenpå rørbendet 7 ved sin ene ende og utenpå sugehodet 2 ved sin andre ende. In fig. 1 shows an extraction fan 1, with a suction head 2 and a hose 3 that runs between the fan and the suction head. The fan consists of a motor 4 that drives the fan wheel (not shown) and a fan casing 5. From the fan casing a central pipe 6 runs outwards, on which a pipe bend 7 is rotatably arranged. On the free end of the pipe bend 7 is attached one or several plates 8, which in turn constitute storage for both a first pivotable arm 9 and one or four tension springs 10, which are only shown schematically with dotted lines in fig. 1. On the end facing away from the fan of the first pivotable arm 9, a largely triangular plate 11 is welded, which forms the attachment for a second pivotable arm 12 as well as one or more outer tension springs 13. The other end of the spring 13 is attached to a knob 14 which projects outwards from the arm 12 and which is close to the outer end of the arm 12. At the outer end of the arm 12, the suction head 2 is pivotably attached at 15. The suction head is equipped with a handle 16 and a damper 17 which is shown in dashed lines. The suction head 2 is pivotable in relation to the arm 12 in a direction shown by arrow 18. The flexible hose 3, which is preferably made of glass fiber reinforced heat-resistant plastic, is threaded on the outside of the pipe bend 7 at one end and on the outside of the suction head 2 at its other end.
I fig. 2 og 3 vises aggregatet i tre ulike stillinger. Still-ingen A utgjør den stilling der sugehodet 2 har den minste avstand til den vegg eller liknende 19, som aggregatet er opphengt på. Still-ingene B og C viser henholdsvis sugehodets 2 maksimale avstand fra veggen 19 og en stilling der sugehodet befinner seg i en avstand mellom de to stillinger A og B, men på et høyere nivå enn i begge disse stillinger. Svingningen av aggregatet i horisontalplanet fremgår av fig. 3. In fig. 2 and 3 show the unit in three different positions. Position A constitutes the position where the suction head 2 has the smallest distance to the wall or similar 19, on which the unit is suspended. The positions B and C respectively show the maximum distance of the suction head 2 from the wall 19 and a position where the suction head is located at a distance between the two positions A and B, but at a higher level than in both of these positions. The oscillation of the unit in the horizontal plane can be seen from fig. 3.
Fig. 4 viser svingeforbindelsene og innfestingen av strekk-fjærene i detalj, idet det er anvendt samme henvisningstall som i fig. 1 for like deler. Fra platene 8 utgår armen 9 som er festet til platene ved hjelp av en bolt og mutter, hvis midtlinje mark-eres med den strekprikkete linje 20. Mellom armen 9 og platene 8 Fig. 4 shows the pivoting connections and the attachment of the tension springs in detail, the same reference number as in fig. 1 for equal parts. Starting from the plates 8 is the arm 9 which is attached to the plates by means of a bolt and nut, the center line of which is marked with the dotted line 20. Between the arm 9 and the plates 8
er det anbrakt friksjonsskiver 21, som fortrinnsvis er fremstilt friction discs 21 are fitted, which are preferably manufactured
av bakelitt. På armens 9 andre ende er platene 11 fastsveiset, slik som antydet ved 22. Armen 12 er festet til platene 11 på liknende måte som armen 9 er festet til platene 8. Friksjonsleddene 23 ut-gjøres i dette tilfelle av skiver 24, som ligger an mot armen 12 med sin ene side og med sin andre side samvirker med friksjonsskiver 25, som igjen ligger direkte an mot platene 11 med sin andre side. For å sikre friksjonen er planskiver 26 og fjærskiver 27 inn satt mellom platen 11 og bolten eller mutteren 28 resp. 29. Gjennom platene 8 og 11 løper aksler 30 resp. 31, hvortil det er festet strekkfjærenes ender. Akselen 30 opptar fjærenes 10 ene ende og akselen 31 fjærenes 10 andre ende samt fjærenes 13 ene ende, idet fjærene 13 i dette tilfelle er festet utenfor fjærene 10. Fjærenes 13 andre ende er festet til en aksel, som går gjennom den knast 14 som er anbrakt på armen 12. of bakelite. At the other end of the arm 9, the plates 11 are welded, as indicated at 22. The arm 12 is attached to the plates 11 in a similar way as the arm 9 is attached to the plates 8. The friction joints 23 are in this case made up of washers 24, which are against the arm 12 with its one side and with its other side cooperates with friction disks 25, which again lie directly against the plates 11 with their other side. To ensure the friction, flat washers 26 and spring washers 27 are inserted between the plate 11 and the bolt or nut 28 resp. 29. Through plates 8 and 11, shafts 30 run respectively. 31, to which the ends of the extension springs are attached. The shaft 30 occupies one end of the springs 10 and the shaft 31 the other end of the springs 10 as well as one end of the springs 13, the springs 13 in this case being attached outside the springs 10. The other end of the springs 13 is attached to a shaft, which passes through the cam 14 which is placed on the arm 12.
