Description

Uppfinnare: K. E. A. Gothberg. Inventor: K. E. A. Gothberg.

Det liar blivit alit vanligare att lager, kugghjul, skarverktyg etc. smorj as medelst olje- dimma, som astadkommes i en s. k. olje- dimbildare med hjalp av komprimerad luft. Oljedimman i vidstrackt bemarkelse ar en heterogen blandning av luft och mer eller mindre finfardelad olja. De minsta oljepartiklarna aro sa sma, att de kunna halla sig lange svavande i luften aven om denna är i stillhet. De bilda med luften den s. k. rena oljedimman, som f8rhaller sig vasentligen som en gas. De storre oljepartiklarna, olje- dropparna, i dimman ha karaktaren av flytande olja. De kunna folja med luften sã lange denna befinner sig i hastig, ratlinig riirelse dock endast for mycket kort tid. De fastna snart pa ledningsrorets vaggar och bilda den mer eller mindre utpraglade strom av flytande olja som man ibland ser i oljedimledningar. It has become increasingly common for bearings, gears, joint tools, etc. to be lubricated by means of oil mist, which is produced in a so-called oil mist former with the help of compressed air. The oil mist in broad sense is a heterogeneous mixture of air and more or less finely divided oil. The smallest oil particles are so small that they can stay long floating in the air even if it is in silence. They form with the air the so-called pure oil mist, which behaves essentially like a gas. The larger oil particles, the oil droplets, in the mist have the character of liquid oil. They can follow the air as long as it is in rapid, linear motion, but only for a very short time. They soon get stuck on the cradle's cradle and form the more or less pronounced stream of liquid oil that is sometimes seen in oil mist lines.

Den rena oljedimman, som forhaller sig som en gas, fordelar sig pa olika grenledningar i proportion till dessa ledningars minsta areor. Den flytande olja, som eventuellt forekommer i rorledningen fordelar sig daremot efter andra lagar och det ar svart, for att inte saga omojligt, att rattvist fordela denna olja mellan olika smorjstallen. Den oljedimma, som skall distribueras till ett flertal smorjstallen genom ett forgrenat rorsystem, utgaende Iran en oljedimbildare, bor darfor vara sá fri Iran flytande olja som mojligt. En oljedimbildare, som levererar praktiskt taget ren oljedimma, kan emellerlid endast drivas upp i en viss begransad kapacitet, ungefar 10 gr olja per in luft. Okad leveransforinaga kan alltsa uppnas endast genom okad luftforbrukning, d. v. s. till extra kostnad, som da det t. ex. galler smorjning av borr- eller brotschverktyg eller sprutsmorjfling av ytor ställer sig for Mgt. For dessa smorjandamal, dar grenledningar i allmãnhot ieke forekomma, brukar man darfor konstruera oljedimbildare sa, att den jamte den rena oljedimman aven levererar en storre eller mindre mangd flytande olja. De olika an vandningsomradena krava darfOr tva olika utfOringsformer av oljedimbildare. The pure oil mist, which behaves like a gas, is distributed on different branch lines in proportion to the smallest areas of these lines. The liquid oil that may be present in the pipeline, on the other hand, is distributed according to other laws and it is black, not to say impossible, to distribute this oil evenly between the different lubrication figures. The oil mist, which is to be distributed to a number of lubrication stables through a branched rudder system, emanating from Iran as an oil mist generator, should therefore be as free of liquid liquid as Iran. An oil mist generator, which delivers practically pure oil mist, can, however, only be propelled up to a certain limited capacity, approximately 10 grams of oil per in air. Increased delivery capacity can thus only be achieved through increased air consumption, i.e. at extra cost, as in the case of e.g. grating lubrication of drilling or reaming tools or spray lubrication of surfaces stands for Mgt. For these lubrication purposes, where branch lines in general threat do not occur, it is therefore customary to construct oil mist formers so that the pure oil mist also delivers a greater or lesser amount of liquid oil. The different areas of irrigation therefore require two different embodiments of oil mist formers.

Foreliggande uppfinning avser i forsta hand att frambringa en oljedimbildare, som kan producera en mycket ren och alltsa olje- besparande oljedimma och i andra hand att astadkomma en oljedimbildare, som pa ett enkelt salt kan andras sa, att den kan anvandas aven i sadana fall, dar man behover en oljedimma, som innehaller storre oljemangder an som kan erhallas med anvandning av endast den rena oljedimman. The present invention is primarily intended to provide an oil mist former which can produce a very clean and thus oil-saving oil mist and secondly to provide an oil mist former which on a single salt can be modified so that it can also be used in such cases. where you need an oil mist, which contains larger amounts of oil than can be obtained using only the pure oil mist.

Uppfinningen avser shdana oljedimbildare, vid vilka ett oljeavskiljande organ är anbragt mellan dimbildningsstallet och avloppet Iran oljedimbildaren och kannetecknas i huvudsak diirav, att fria passager for stralen iiro anordnade pa hada sidor om avskiljningsorganet. Enligt ett speciellt utforande dr avskiljningsorganet helt eller delvis fOrflyttbart ur stralens bana. The invention relates to such oil mist formers, in which an oil separating means is arranged between the mist formation stall and the drain Iran oil mist former and can be characterized mainly by the fact that free passages for the jet are arranged on either side of the separating means. According to a special embodiment, the separating member is completely or partially movable out of the path of the beam.

Nagra utforingsformer av uppfinningen aska.dliggores pa bifogade ritning, i vilken fig. 1 visar en langdsektion genom en dimbildare, anordnad for alstrande av en ren dimma. Fig. 2 visar en tvarsektion genom dimbildaren efter linjeni fig. 1. Fig. 3 visar en vertikal sektion genom en del av dimbildaren anordnad for smorjning med stora oljemangder och fig. 4 och 5 visa del- sektioner av en installningsanordningom- stallning av dimbildaren fran det ena funktionssattet till det andra. Some embodiments of the invention are illustrated in the accompanying drawing, in which Fig. 1 shows a longitudinal section through a mist former, arranged to produce a pure mist. Fig. 2 shows a cross section through the mist former according to the line in Fig. 1. Fig. 3 shows a vertical section through a part of the mist former arranged for lubrication with large oil quantities and Figs. 4 and 5 show sub-sections of an installation device conversion of the mist former from one mode of operation to the other.

Oljedimbildaren enligt fig. 1 bestar av en oljebehallare 1, i vilken ar anbragt ett stigror 2 for olj an ledande till ett spridarmunstycke 3. Munstycket 3 anslutes till en tryckluftkalla (ej visad), varvid dimman bildas pa kant satt i munstycket och Hires fram av luftstralen och avgar genom den mittemot munstyeket belagna avloppsoppningen 4. Vid bildandet av oljedimman bemanges denna med olja i form av droppar, som kan utgora anda upp till c:a 98 % av den avgaende oljemangden, om joke sarskilda anordningar vidtagas for att skilja ifran oljan. Enligt upp- 2— — finningen ãr i oljedimmans bana mellan det dar oljedimman bildas, d. v. s. spridarmunstycket och avloppsoppningen 4 anbragt ett oljeavskiljningsorgan 5, vilket sasom framgar av fig. 2 i foreliggande fall har en mer eller mindre hjart- eller plogform. Vid vardera sidan am organet 5 aro anordnade kanaler 6 resp. 7 mellan organet 5 och den omgivande vaggen 8 till behalIaren. Oljedimstrommen, som traffar organet 5, delas av organets framre kant eti tva delar, vilka av- lankas at bada sidor utan att nanonvard stOteffekt uppkommer, varigenom forhindras, att olja stanker ut fran organet och ryckes med in ftstr6m men. The oil mist generator according to Fig. 1 consists of an oil container 1, in which a riser 2 for oil is arranged leading to a spray nozzle 3. The nozzle 3 is connected to a compressed air source (not shown), whereby the mist is formed on the edge set in the nozzle and Hires forward by air jet and exits through the drain opening located opposite the nozzle 4. When forming the oil mist, it is charged with oil in the form of droplets, which can constitute spirit up to about 98% of the outgoing oil quantity, if joke special devices are taken to separate the oil . According to the invention, an oil separating means 5 is arranged in the path of the oil mist between the formation of the oil mist, i.e. the spreading nozzle and the drain opening 4, which as shown in Fig. 2 in the present case has a more or less heart or plow shape. At each side of the member 5 there are arranged channels 6 resp. 7 between the member 5 and the surrounding cradle 8 to the container. The oil mist stream, which strikes the member 5, is divided by the leading edge of the member into two parts, which elongate on both sides without any significant impact effect, thereby preventing oil from stinking out of the member and being pulled in by the flow.

Alla i stralen befintliga oljepartiklar maste antingen andra rorelseriktning eller stota mot organet 5. De storm oljepartiklarna kunna emellertid kite andra sin rorelseriktning pa grund av sin massa och hastighet, varfor de komma att fastna pa organets 5 vagg och sâ smaningom falla tillbaka i oljebadet frail vaggens understa kant. Hãr gripas de och fOras tillbaka i riktning fran avloppsOppningen av en bakatriktad luftstrom utgorande en del av den virvel, som alstras sekundart i luftrummet under den horisontella stritlen. Dropparna falla darfor snett bakat tillbaka i oljebadet.• De minsta, ytterst sma oljepartiklarna dar- emot forbli blandade med luften och passera tillsammans med denna genom passagerna 6 och 7 pa omse sidor om viiggen i form av mycket ren oljedimma. Av den oljemangd, som ingar i dimman utgtires endast ett par procent av flytande olja och de c :a 98 5, forekommer i form av finfordelad olja. Reningen av oljedimman dr saledes synnerligen effektiv. All the oil particles present in the jet must either move in the other direction or strike the body 5. However, the storm oil particles can change their direction of movement due to their mass and velocity, so that they get stuck on the body's cradle and eventually fall back into the oil bath. bottom edge. Here they are gripped and carried back in the direction of the drain opening of a rearwardly directed air stream forming part of the vortex, which is generated secondarily in the air space below the horizontal strip. The droplets therefore fall obliquely back into the oil bath. • The smallest, extremely small oil particles, on the other hand, remain mixed with the air and pass together with it through passages 6 and 7 on opposite sides of the cradle in the form of very clean oil mist. Of the oil content, which enters the mist, only a few percent of liquid oil is extracted and the approx. The cleaning of the oil mist is thus extremely effective.

Organet 5 kan goras I ett stycke med loc- ket 10 till oljedimbildaren men kart aven Bled fordel &as separat, i vilket senare fall det kan t. ex. gams hoj- och sankbart, sasom visas i figurerna. Vid den I fig. 1-3 visade utfaringsformen fasthalles organet 5 vid locket 10 medelst ett par bultar 11 och muttrar 12. I fig. I visas organet i sitt ovre lage anliggande mot locket och anbragt Indian dimbildningsstallet och avloppet fran oljedimbildaren. Mellan organet 5 och muttrarna 12 hr da anbragt ett par avstandsstycken 13 och 14, av vilka avstandsstycket 13 hr dubbelt sã hogt som avstandsstycket 14. Genom omflyttning av avs•tandsstyckena pa lampligt satt, sa att de ligga over eller under organet 5 kan detta bringas att inta Ire olika lagen utom det lage, som visas i fig. 1, dar det verkar fullstandigt oljeavskiljande, sa att den utgaende oljedimman dr praktiskt taget fri Iran olja. I de olika lagena verkar organet 5 mer eller mindre oljeavskiljande. Ju hOgre det befinner sig desto stOrre del hr det av de i stralen forekommande oljedropparna, som hejdas och skiljas ur oljedimman, innan denna lamnar apparaten. The member 5 can be made in one piece with the lid 10 of the oil mist former, but also Bled is distributed separately, in which later case it can e.g. gams can be raised and lowered, as shown in the figures. In the embodiment shown in Figs. 1-3, the member 5 is secured to the lid 10 by means of a pair of bolts 11 and nuts 12. In Fig. 1 the member is shown in its upper layer abutting the lid and arranged the Indian mist formation stall and the drain from the oil mist former. A pair of spacers 13 and 14 are then arranged between the member 5 and the nuts 12, of which the spacer 13 is twice as high as the spacer 14. By moving the spacers in a suitable manner so that they lie above or below the member 5, this can be brought to take Ire different laws except the law, shown in Fig. 1, where it seems completely oil-separating, so that the outgoing oil mist dr practically free Iran oil. In the different layers the member 5 acts more or less oil-separating. The higher it is, the greater the proportion of the oil droplets present in the jet, which are stopped and separated from the oil mist before it leaves the appliance.

I det nedersta higet, som visas i fig. 3, dar bada avstandsstyckena dro anbragta ovanfor avskiljningsorganet, lamnar det stralens vag fri och inverkar salunda praktiskt taget inte pa den ur munstycket kommande stralen och all olja, som finnes i stralen, kommer foljaktligen att fortsatta ut genom apparatens avlopps4pning. In the lower height, shown in Fig. 3, where both spacers are located above the separator, it leaves the beam of the jet free and thus practically does not affect the jet coming from the nozzle and all oil contained in the jet will consequently continue. out through the drain of the appliance.
