Description

Uppfinnare: C 0 Malmstrom och B 0 M Palm Bet är kant att i brannarroret till en oljebrannare anbringa en turbulator, dvs. ett antal stillastaende ledskeneartade vingar, som Aro anordnade att bibringa forbranningsluften en kraftig turbulens, innan den nar Irani till oljedysan. Inventors: C 0 Malmstrom and B 0 M Palm Bet are the edge to apply a turbulator to the oil burner of an oil burner, ie. a number of stationary hinge-like wings, which Aro arranged to impart a strong turbulence to the combustion air, before it reaches Irani to the oil nozzle.

Det fir oxen kant att i lufttillforselledningen till en oljebrannare anbringa ett spjall, varmed luittillforseln kan avstangas under de tidsperioder, da hrannaren joke brinner. The ox edge must be fitted with a damper in the air supply line to an oil burner, with which the air supply can be shut off during the time periods when the burner joke is burning.

Bet har visat sig onskvart att anbringa turbulatorvingarna i en viss bestamd hitningsvinkel for att fâ basta effekt pa. forbranningen. Derma optimala lutningsvinkel har emellertid visat sig vara beroende joke endast av brannarens konstruktion, utan aven av eldstadens utformning och skorstenens sjalvdrag, varfor det blivit nadvandigt att antingen lagerfora ett antal turbulatorer med olika lutning pa. vingarna eller noj a sig med en turbulator med mindre god verkan. Beet has been found to be inconvenient to place the turbulator blades at a certain fixed angle of inclination in order to have the best effect on. the combustion. However, these optimal inclination angles have been found to depend only on the design of the burner, but also on the design of the fireplace and the draft of the chimney, so that it has become necessary to either stock a number of turbulators with different inclinations. the wings or satisfy yourself with a turbulator with less good effect.

Fi3religgande uppfinning avser en anordning vid turbulatorer for oljebrannare, vid vilken turbulatorvingarna aro fasta pa var sin axel, som ar vridbart lagrad i ett pa. oljetillforselroret till oljedysan fast nay, sa att axlarna Aro radiellt riktade, och pa. var och en av axlarna dr invid navet fast ett koniskt kugghjul, samt pa navet ar vridbart lagrat ett med oljetillforselroret koaxiellt koniskt kugghjul, som Sr anordnat att gripa in i axlarnas kugghjul, och dr anordnat att kunna vridas fran brannarens utsida. The present invention relates to a device for turbulators for oil burners, in which the turbulator blades are fixed on their respective shafts, which are rotatably mounted in one shaft. the oil supply tube to the oil nozzle fixed nay, so that the axes Aro radially directed, and pa. each of the shafts there is attached to the hub a conical gear, and on the hub is rotatably mounted a conical gear coaxial with the oil supply pipe, which is arranged to engage in the gears of the shafts, and there arranged to be rotatable from the outside of the burner.

Anordningen enligt uppfinningen kannetecknas darav, att axlarna med de pa. dein fasta koniska kugghjulen aro anordnade att hallas kvar med kugghjulen anliggande mot navet enbart av en exempelvis pa det i dem ingripande kugghjulet fast, over de f8rst naninda kugghjulens kuggkransar utskj utande sarg. The device according to the invention can be characterized in that the axes with the pa. The fixed bevel gears are arranged to be retained with the gears abutting the hub only by, for example, on the gear engaging them fixedly projecting over the gear naninda of the gear rings.

Uppfinningen fortydligas av den bifogade ritningen som visar en utforingsform av en anordning enligt uppfinningen, sedd i hangssektion. oljetillforselroret 1 till en oljebrannare är strax innanfor oljedysan 2 fast ett nay 3. Detta nay 3 ãr forsett med ett antal radiellt riktade cylindriska urtagningar 4. I var och en av dessa urtagningar 4 är en axel 5 vridhart lagrad, vilken axel 5 i sin yttre ande är forsedd med en lampligen plan yinge 6. Mellan vingen 6 och navet 3 ar axeln 5 forsedd med ett koniskt kugghjul 7. The invention is clarified by the accompanying drawing which shows an embodiment of a device according to the invention, seen in hanging section. the oil supply tube 1 of an oil burner is just inside the oil nozzle 2 fixed to a nay 3. This nay 3 is provided with a number of radially directed cylindrical recesses 4. In each of these recesses 4 a shaft 5 is rotatably mounted, which shaft 5 in its outer The shaft 5 is provided with a suitably flat yinge 6. Between the wing 6 and the hub 3 the shaft 5 is provided with a conical gear 7.

PA navet 3 ar ett koniskt kugghjul 8 vridhart lagrat koncentriskt med oljetillforselroret 1 och sa, att det griper in i de koniska kugghjulen 7 pa axlarna 5. Kugghjulet 8 Sr vid sin periferi forsett rued en utanfor dess kuggar utskjutande sarg 9, som Sr anordnad att sticka ut Over kugghjulen 7 och halla dessa i anliggning mot navet 3. Pa kugghjulet 8 Sr fast en ring 10 med invandiga kuggar, vilken halles i anliggning mot navet 3 av en pa detta fast flans 11. ON the hub 3 a conical gear 8 is rotatably mounted concentrically with the oil supply tube 1 and so that it engages the conical gears 7 on the shafts 5. The gear 8 is provided at its periphery with a protruding edge 9 projecting outside its teeth, which is arranged to protrude above the gears 7 and hold them in abutment against the hub 3. On the gear 8 Attach a ring 10 with internal teeth, which is held in abutment against the hub 3 by a fixed flange 11 on this.

Ett kuggdrev 12 är anordnat att ingripa i ringens 10 invandiga kuggar och dr fast pa en med oljetillforselroret 1 parallell axel 13, som larapligen ar vridbart lagrad i flansen. 11 och nar ut till brannarens utsida. A gear 12 is arranged to engage the inner teeth of the ring 10 and fasten to a shaft 13 parallel to the oil supply tube 1, which is rotatably mounted in the flange. 11 and reaches out to the outside of the burner.

Vingarna 6 aro i sin yttre ande forsedda med nabbar 14, som aro koaxiala med axlarna 5 och anordnade att kunna stoda mot brannarroret 15. The wings 6 are in their outer spirit provided with hubs 14, which are coaxial with the shafts 5 and arranged to be able to stand against the fire tube 15.

Navels 3 periferi är lampligen utformad som en sfarisk ekvatorialzon. The periphery of the navel 3 is aptly designed as a spherical equatorial zone.

I brannarraret 15 Sr vid dettas mynning anbragt en fortrangning 16, vars insida ar 2— — utformad som en halv sfarisk ekvatorialzon med sitt centrum i navets 3 centrum. Vingarna 6 aro pa sin utsida och insida begransade av cirkelbagar med sitt centrum I navets 3 centrum, sa att deras insidor komma att fOlja navets 3 periferi, och deras utsidor komma att folja fortrangningens 16 insida, hur vingarna 6 an vridas. In the fire arrester 15 is located at its mouth a displacement 16, the inside of which is 2 - - formed as a semi-spherical equatorial zone with its center in the center of the hub 3. The wings 6 are on the outside and inside are bounded by circular beetles with their center in the center of the hub 3, so that their insides will follow the periphery of the hub 3, and their outside will follow the inside of the displacement 16, as the wings 6 are rotated.

Det liar visat sig fOrdelaktigt att utforma navets 3 centrum som en fattning for oljedysan 2, varigenom den pa ritningen visade dyshallaren 17 kan slopas. It has proved advantageous to design the center of the hub 3 as a socket for the oil nozzle 2, whereby the nozzle holder 17 shown in the drawing can be disposed of.

Om kugghjulet 8 fastes pa ett pa oljetillforselroret 1 vridbart lagrat rOr, kunna ringen 10, kugghjulet 12 och axeln 13 slopas. If the gear 8 is attached to a tube rotatably mounted on the oil supply pipe 1, the ring 10, the gear 12 and the shaft 13 can be released.

Det liar visat sig lampligt att Horse minst tvit av vingarna 6 med urtagningar 18 for tandelektroderna. It has been found fitting that Horse at least twists the wings 6 with recesses 18 for the tooth electrodes.

Om vingarnas 6 bredd gores sit stor, att tvit narliggande vingar 6 ga kant i kant, nar de anbringas vinkelratt mot brannarroret 15, kunna vingarna 6 Even tjanstgara som stangningsspja.11 for forbranningsluften. Manoveraxeln 13 kan da med fordel anslutas till en regulator, som automatiskt vrider vingarna 6 till vinkelratt lage mot brannarroret 15, sit snart oljetillforseln till dysan 2 upphor. If the width of the wings 6 is made so large that two adjacent wings 6 go edge to edge, when they are placed at right angles to the fire tube 15, the wings 6 can even serve as a shut-off valve 11 for the combustion air. The control shaft 13 can then advantageously be connected to a regulator, which automatically turns the wings 6 to an angular steering wheel bearing against the fire tube 15, if the oil supply to the nozzle 2 ceases soon.

Med hjalp av den harovan beskrivna anordningen moter det ingen svarighet att bibringa vingarna 6 den lutning, som ger den for en fullstandig fOrbranning gynnsammaste turbulensen hos forbranningsluften. By means of the device described above, there is no reason to impart to the wings 6 the inclination which gives it the most favorable turbulence of the combustion air for a complete combustion.

Ehuru liar ovan endast ett par utforingsformer visats och beskrivits, kunna aven andra forekomma mom uppfinningens ram. Although only a few embodiments have been shown and described above, others may occur within the scope of the invention.
