Description
Anordning ved oljeopphetet ovn. Device for an oil-heated oven.
Oljeopphetede ovner er kjent, som i det vesentlige består av en oljebeholder som hviler i et bærestativ og hvor der over olje-holderen er anordnet et varmerør som utvider seg konisk oppover og går over i et sylindrisk brennrør. Varmerøret er forsynt med slisser, slik at oksygen i tilstrekkelig mengde tilføres til forbrenning av oljedampene. De deler av oljedampene som ikke blir fullstendig forbrent, føres over et tilbakeløpsrør tilbake til olj eoverf laten. Dette tilbakeløpsrør er ført gjennom det sylindriske brennrørs vegg og ender i midten av dette rørs indre. Oil-heated furnaces are known, which essentially consist of an oil container which rests in a support frame and where a heating pipe is arranged above the oil holder which expands conically upwards and transitions into a cylindrical combustion pipe. The heating pipe is provided with slits, so that sufficient oxygen is supplied to burn the oil vapours. The parts of the oil vapors that are not completely burned are led via a return pipe back to the oil above the bed. This return pipe is led through the wall of the cylindrical combustion pipe and ends in the middle of this pipe's interior.
Mellom det koniske rør og oljebeholderen er der anordnet en strupeklaff for regulering av varmeydelsen. Oljebeholderens lokk er forsynt med en inntaksåpning som er dekket med en kapsel. For anten-nelse av ovnen stikkes der gjennom denne kapsel en lunte som tjener til å forgasse endel av oljebeholderens innhold, og som ved overskridelsen av tenntemperaturen antenner dette gasskikt. Between the conical tube and the oil container there is a throttle valve for regulating the heating output. The oil container's lid is provided with an intake opening which is covered with a capsule. To ignite the furnace, a fuse is inserted through this capsule, which serves to gasify part of the oil container's contents, and which, when the ignition temperature is exceeded, ignites this layer of gas.
Kapslen som dekker ifyllingsåpningen, er perforert, idet hullene i kapslen samarbeider med en hullskive for å regulere oksy-gentilførslen. I alle tilfelle skal der unngåes at oljebeholderen får tilført for meget oksygen, idet der da er fare for at flammer slår ut av brennrøret, hvilke lett kan frem-bringe en brann. The capsule that covers the filling opening is perforated, as the holes in the capsule cooperate with a perforated disk to regulate the oxygen supply. In all cases, it must be avoided that too much oxygen is supplied to the oil container, as there is then a danger of flames breaking out of the combustion tube, which can easily cause a fire.
Av denne grunn må man hindre at den kapsel som dekker ifyllingsåpningen, ved uforsiktighet etter tenningen av ovnen bringes i åpen stilling. For this reason, care must be taken to prevent the capsule covering the filling opening from being brought into the open position after lighting the oven.
For at en oljeovn skal arbeide perfekt For an oil furnace to work perfectly
er det ennvidere nødvendig at strupeklaffen etter antennelsen blir stående i åpen stilling, da ovnen ellers vil ha tendens til sterk røkutvikling. Ved de kjente utførelser sørges der ikke for at strupeklaffen blir stående i åpen stilling, slik at den som følge av rystelser, f. eks. på grunn av i nærheten arbeidende maskiner, kan svinges til lukket stilling. is it still necessary for the throttle valve to remain in the open position after ignition, as otherwise the stove will tend to develop strong smoke. With the known designs, it is not ensured that the larynx remains in the open position, so that as a result of vibrations, e.g. due to machinery working nearby, can be swung to the closed position.
Oppfinnelsen tar sikte på å unngå disse ulemper ved en oljeopphetet ovn, hvor et reguleringslokk lukker en ifyllingsstuss oppad, og hvor ifyllingsstussen som er forbundet med ifyllingsåpningen og er ført inn i oljebeholderens indre, er forsynt med langsgående slisser. Oppfinnelsen utmerker seg ved at en bimetallstrimmel som er festet på undersiden av den kapsel som dekker ifyllingsåpningen, har utløpere som samarbeider med nevnte slisser når en bestemt temperatur av strimlen overskides. The invention aims to avoid these disadvantages of an oil-heated oven, where a regulating lid closes a filling nozzle upwards, and where the filling nozzle, which is connected to the filling opening and is led into the interior of the oil container, is provided with longitudinal slits. The invention is distinguished by the fact that a bimetallic strip which is attached to the underside of the capsule which covers the filling opening, has spurs which cooperate with said slits when a certain temperature of the strip is exceeded.
Et ytterligere trekk ved oppfinnelsen utmerker seg ved at strupeklaff ens betje-ningsarm ved hjelp av en fjærbøyle fastholdes i åpen stilling. A further feature of the invention is distinguished by the fact that the throttle valve's operating arm is held in the open position by means of a spring clamp.
Disse og andre trekk ved oppfinnelsen vil fremgå av følgende beskrivelse av teg-ningene, hvor fig. 1 viser en oljeopphetet ovn i oppriss, fig. 2 en detalj, fig. 3 reguler-ingskapslen i snitt, fig. 4 et snitt etter lin-jen IV—IV på fig. 3, fig. 5 ovnen ifølge fig. 1 med en mantel anbragt utenpå varme-røret, fig. 6 denne mantel sett i oppriss for å vise de deri foretatte utsparinger, og fig. 7 er grunnriss av mantelen ifølge fig. 6. These and other features of the invention will be apparent from the following description of the drawings, where fig. 1 shows an oil-heated oven in elevation, fig. 2 a detail, fig. 3 the regulation capsule in section, fig. 4 a section along the line IV—IV in fig. 3, fig. 5 the oven according to fig. 1 with a jacket placed on the outside of the heating pipe, fig. 6 this mantle seen in elevation to show the recesses made therein, and fig. 7 is a plan view of the mantle according to fig. 6.
På fig. 1 betegner 1 et stativ som bærer oljebeholderen 2. Denne oljebeholder har et lokk 3 som i midten er forbundet med et varmerør 4 som utvider seg konisk oppad og er forsynt med slisser 5 for tilførsel av den til forbrenningen nødvendige luft. Var-merøret går over i et sylindrisk brennrør 6. For å oppnå en mest mulig fullstendig forbrenning føres de deler av gassen som ikke forbrenner i brennrøret 6, tilbake til beholderen 2 gjennom et tilbakeløpsrør 7 som mnner ut over oljenivået i beholderen 2. In fig. 1 denotes 1 a stand which carries the oil container 2. This oil container has a lid 3 which is connected in the middle to a heating pipe 4 which expands conically upwards and is provided with slots 5 for supplying the air required for combustion. The heater tube passes into a cylindrical combustion tube 6. In order to achieve the most complete combustion possible, the parts of the gas that do not burn in the combustion tube 6 are led back to the container 2 through a return pipe 7 which exits above the oil level in the container 2.
Lokket 3 har en ifyllingsåpning som er dekket til med en kapsel 8 som er vist særskilt på fig. 3 og er perforert. Per-forasjonsåpningene samvirker med en hullskive 9 for regulering av den tilførte sekun-dærluft. Kapslen 8 er ved 10 hengselfor-bundet med lokket 3. Ifyllingsåpningen har en ifyllingsstuss 11 som er forsynt med langsgående slisser 12 og 13 i sideveggen. The lid 3 has a filling opening which is covered with a capsule 8 which is shown separately in fig. 3 and is perforated. The perforation openings cooperate with a perforated disc 9 for regulating the supplied secondary air. The capsule 8 is hinged at 10 to the lid 3. The filling opening has a filling nozzle 11 which is provided with longitudinal slits 12 and 13 in the side wall.
Under lokket 3 er ved hjelp av en skrue 14 eller liknende festet en bimetallstrimmel 15 som har form av en halv sirkelbue. Etter at ovnen er antent og en bestemt temperatur nådd, øker bimetallstrimlens krum-ningsradius slik at dens utadrettede frem-spring 16 og 17 automatisk glir inn i leng-deslissene 12 og 13, slik at der mellom klaf-fen 8 og ifyllingsstussen 11 tilveiebringes en forbindelse som først oppheves når ovns-temperaturen kommer under en bestemt grense. Under the lid 3, a bimetallic strip 15 which has the shape of a semicircular arc is attached by means of a screw 14 or the like. After the furnace is ignited and a certain temperature is reached, the radius of curvature of the bimetallic strip increases so that its outward projections 16 and 17 automatically slide into the longitudinal slits 12 and 13, so that between the flap 8 and the filling nozzle 11 a connection which is only canceled when the oven temperature falls below a certain limit.
Det er fordelaktig å la bimetallstrim-melens ene ben ligge lavere enn det annet, slik at sperringen ved hjelp av bimetall-strimmelen inntrer ved forholdsvis lave temperaturer. It is advantageous to leave one leg of the bimetallic strip lower than the other, so that the blocking by means of the bimetallic strip occurs at relatively low temperatures.
Ved anordningen av bimetallsperringen hindres at kapslen 8 ved uforsiktighet kan åpnes mens ovnen er i drift, hvilket ville kunne bevirke brann. The arrangement of the bimetallic barrier prevents the capsule 8 from being carelessly opened while the oven is in operation, which could cause a fire.
Til regulering av varmeavgivelsen er For regulating the heat release is
der mellom beholderen 2 og varmerøret 4 innkoplet en strupeklaff 18 som kan svinges for hånd ved hjelp av en arm 19. For å unngå at strupeklaffen skal forandre stilling som følge av rystelser, fastholdes strupeklaffen i åpen stilling ved hjelp av en fjærbøyle 20 som samvirker med armen 19. Fjærbøylen 20 har en utsparing 21 som where between the container 2 and the heating pipe 4 a throat valve 18 is connected which can be swung by hand with the help of an arm 19. In order to prevent the throat valve from changing its position as a result of vibrations, the throat valve is held in the open position by means of a spring clamp 20 which cooperates with the arm 19. The spring bracket 20 has a recess 21 which
griper rundt armen 19 og sørger for at denne fastholdes. grips around the arm 19 and ensures that this is retained.
Det er også fordelaktig å anordne en perforert mantel 22 omkring varmerøret 5. Denne mantel, som er vist på fig. 5, 6 og 7, har utsparinger 23 og 24, hvor den første gir adgang til reguleringsklaffen 8 og den annen gir plass for tilbakeløpsrøret 7. It is also advantageous to arrange a perforated jacket 22 around the heating pipe 5. This jacket, which is shown in fig. 5, 6 and 7, have recesses 23 and 24, where the first provides access to the control valve 8 and the second provides space for the return pipe 7.
