Abstract

In an oscillating liquid spray-nozzle with a turbine (4, 6, 22), which is driven by the force of flowing liquid, and via an eccentric mechanism (21, 7), a nozzle holder (10) with a nozzle opening (19) is deployed to effect an oscillating movement. The innovative feature lies in the fact that the nozzle housing's inlet part (1) and outlet part (8), together with the turbine (4, 6, 22) are mainly arranged symmetrically on a joint axis (23).In this way, a minimum of pressure drop in the turbine, along with a simplification of assembly and maintenance, is achieved.<IMAGE>

Description

i DK 166437 B1in DK 166437 B1

Opfindelsen angår en oscillerende væskeudsprøjtningsdyse af den i krav 1's indledning angivne art.The invention relates to an oscillating fluid injection nozzle of the kind set forth in the preamble of claim 1.

Tidligere foreslåede dyser af denne art, hvoraf eksempler 5 kendes fra GB-patentskrift nr. 2.063.714 og DK-fremlæg-gelsesskrift nr. 156.158, er behæftet med visse ulemper.Previously proposed nozzles of this kind, examples 5 of which are known from GB Patent Specification No. 2,063,714 and DK Patent Specification No. 156,158, have certain disadvantages.

De af disse ulemper, der er af driftsmæssig art, er for det første et usymmetrisk udsprøjtningsmønster, der skyldes, at dysens drivmekanisme bevæger denne med forskel-10 lige hastigheder omkring de to yderstillinger. For det andet bevirker udformningen af turbinen på lignende måde som en Pelton-turbine store hvirveldannelser og deraf følgende betydeligt trykfald i turbinen, således at der er mindre tryk til rådighed til udsprøjtning af strålen. Af 15 andre uemper kan nævnes et besværligt montagearbejde og deraf følgende besværligt vedligeholdelsesarbejde, samt en uhensigtsmæssig ydre udformning, hvilke ulemper i stor udstrækning kan tilskrives turbineaksens orientering vinkelret på dysens udstrømningsakse, eller - mere eksakt -20 parallelt med dysens oscillationsakse.First of all, these disadvantages, which are operational, are an asymmetrical spray pattern, due to the nozzle drive mechanism moving it at different speeds around the two outer positions. Second, the design of the turbine similarly to a Pelton turbine causes large turbulence and consequent significant pressure drop in the turbine, so that less pressure is available to spray the jet. Of 15 other drawbacks, there is cumbersome assembly work and consequent cumbersome maintenance work, as well as an improper exterior design, which disadvantages can be largely attributed to the orientation of the turbine axis perpendicular to the nozzle discharge axis, or - more precisely -20 parallel to the nozzle oscillation axis.

De ovenfor omtalte ulemper afhjælpes eller undgås helt ved en dyse af den indledningsvis nævnte art, som ifølge opfindelsen er ejendommelig ved de i krav l’s kendetegnende del angivne træk. Denne udformning muliggør på enkel 25 måde for det første, at dysens oscillationshastighedsmønster bliver symmetrisk om midteraksen, således at udsprøjtningsmønsteret ligeledes bliver symmetrisk, og for det andet, at turbinen kan udformes med "fuldt påslag", der giver en ringe gennemstrømningsmodstand, til forskel 30 fra de turbiner, hvori der anvendes en drivdyse. Opdelingen af dysehuset i to dele på den angivne måde medfører en betydelig forenkling af montage- og vedligeholds-arbej det.The above-mentioned drawbacks are remedied or avoided entirely by a nozzle of the type mentioned initially, which according to the invention is characterized by the features of claim 1. This design allows, in a simple way, firstly that the oscillation velocity pattern of the nozzle be symmetrical about the center axis, so that the ejection pattern becomes symmetrical as well, and secondly that the turbine can be designed with "full load" which gives a low flow resistance, unlike 30 from the turbines in which a drive nozzle is used. The division of the nozzle housing into two parts in the specified manner results in a considerable simplification of the installation and maintenance work.

Krav 2 og 3 omhandler hensigtsmæssige udførelsesformer, 35 der har været prøvet i praksis.Claims 2 and 3 deal with suitable embodiments that have been tried in practice.

DK 166437 B1 2DK 166437 B1 2

Ved dyser af den her omhandlede art er det ofte nødvendigt at forhindre, at turbinen løber for hurtigt, og dette kan på enkel måde opnås ved den i krav 4 angivne udførelses-5 form. De til bremsespalten grænsende vægge kan være glatte, eller den ene eller begge kan være udformet med ribber eller lignende til forøgelse af bremseeffekten.In the case of nozzles of this type, it is often necessary to prevent the turbine from running too fast and this can be achieved in a simple manner by the embodiment of claim 4. The walls adjacent to the brake slit may be smooth, or one or both may be formed with ribs or the like to increase the braking effect.

Ved den i krav 5 angivne udførelsesform opnås en yderligere lettelse af arbejdet med at samle eller adskille de 10 to dele af dysehuset.In the embodiment of claim 5, further relief is obtained from the work of assembling or separating the two two parts of the nozzle housing.

Ved den i krav 6 angivne udførelsesform opnås, at arealet af den del af den i husets udløbsdel anbragte leje- og tætningsflåde, der tilvejebringer tætningen, forbliver konstant, selv efter nedslidning under længere tids brug.In the embodiment of claim 6, it is achieved that the area of the portion of the bed and sealing fleet arranged in the outlet portion of the housing which provides the seal remains constant even after long-term wear.

15 Opfindelsen skal i det følgende forklares nærmere under henvisning til det på tegningen til dels skematisk viste udførelseseksempel på en oscillerende, turbinedrevet væskeudsprøjtningsdyse ifølge opfindelsen, idet fig. 1 viser dysen i aksialsnit, 20 fig. 2 er et snit efter linien B-B i fig. 1, fig. 3 viser turbinens ledeskovlkrans set fra indløbs siden, og fig. 4 viser den i fig. 3 viste ledeskovlkrans, set fra siden og delvis i snit efter linien A-A i fig. 3. 1 2 3 4 5 6BRIEF DESCRIPTION OF THE DRAWINGS In the following, the invention will be explained in more detail with reference to the exemplary embodiment of an oscillating turbine-driven liquid injection nozzle according to the invention, in the drawing. 1 shows the nozzle in axial section, FIG. 2 is a section along line B-B of FIG. 1, FIG. 3 is a side view of the turbine guide vane wreath; and FIG. 4 shows the one in FIG. 3 is a side view, partly in section, along line A-A of FIG. 3. 1 2 3 4 5 6

Den på tegningen viste oscillerende dyse omfatter et i alt 2 væsentligt rotationssymmetrisk dysehus bestående af en 3 indløbsdel 1 og en udløbsdel 8, som i det viste eksempel 4 holdes sammen ved hjælp af et i indløbsdelen 1 udformet 5 indvendigt gevind 28 og et hertil svarende, uden på 6 udløbsdelen 8 udformet udvendigt gevind 29. I stedet for gevind kan der også anvendes andre samlinger, såsom en bajonetsamling eller lignende.The oscillating nozzle shown in the drawing comprises a total of 2 substantially rotationally symmetrical nozzle housings consisting of a 3 inlet portion 1 and an outlet portion 8, which in the illustrated example 4 are held together by means of an internal thread 28 formed in the inlet portion 1 and a corresponding thread. external thread 29. formed on the 6 outlet member 8 instead of threads, other joints, such as a bayonet joint or the like, can also be used.

DK 166437 B1 3 I indløbsdelen 1 er der udformet en væsketilførselsåbning 17, som antydet med gevind, hvormed dysen kan forbindes med et væsketilførselsrør. I dysehusets modsatte ende er 5 der i udløbsdelen .8 udformet en væskeudløbsåbning 18, hvorigennem en ikke vist væskestråle fra en åbning 19 i en dysebærer 10 kan strømme under dysens drift.DK 166437 B1 3 In the inlet part 1 a liquid supply opening 17 is indicated, as indicated by threads, with which the nozzle can be connected to a liquid supply pipe. At the opposite end of the nozzle housing 5, a liquid outlet opening 18 is formed in the outlet portion 8. through which a liquid jet not shown from an opening 19 in a nozzle carrier 10 can flow during the operation of the nozzle.

Dysebæreren 10 er med en på tegningen nedadvendende leje-og tætningsflade ,25 lejret og tætnet imod en leje- og 10 tætningsflade 26, 30, der er udformet på et ringformet leje- og tætnings legeme 9, der er anbragt i udløbsdelen 8 inden for væskeudløbsåbningen 18. Ved hjælp af en konisk skruetrykfjeder 14, hvis på tegningen øverst beliggende ende støtter mod en del af udløbsdelen 8, holdes dyse-15 bæreren 10 til stadighed i anlæg mod leje- og tætningslegemet 9.The nozzle carrier 10 is lined and sealed against a bearing and sealing surface 26, 30 which is facing downwardly in the drawing, which is formed on an annular bearing and sealing body 9 arranged in the outlet part 8 within the liquid outlet opening. 18. By means of a tapered screw spring 14, if at the upper end of the drawing supporting a part of the outlet part 8, the nozzle support 10 is kept constantly in contact with the bearing and sealing body 9.

Dysebæreren 10 er således lejret i forhold til leje- og tætningslegemet 9, at dysebæreren kan svinge om en oscillationsakse 20, der forløber på tværs af rotations-20 aksen 23 for en turbine, der skal beskrives nærmere i det følgende. Dysebæreren 10 er permanent eller udskifteligt forbundet med en excentermedbringer 7, der på den i fig. 1 og 2 viste måde samvirker med en excenter 21, der drives af turbinen. 1 2 3 4 5 6 7 8 9 10 11The nozzle carrier 10 is so positioned relative to the bearing and sealing body 9 that the nozzle carrier can pivot about an oscillation axis 20 extending transverse to the axis of rotation 23 of a turbine to be described in more detail below. The nozzle carrier 10 is permanently or interchangeably connected to an eccentric carrier 7 which, in the embodiment shown in FIG. 1 and 2 interact with an eccentric 21 driven by the turbine. 1 2 3 4 5 6 7 8 9 10 11

Turbinen, der nærmest kan betegnes som en forenklet 2The turbine, which can almost be described as a simplified 2

Francis-turbine, består af en bæreplade 3, der er ind 3 spændt mellem de to husdele 1 og 8, som på dette sted er 4 indbyrdes tætnet ved hjælp af en O-ring 2, en på bære 5 pladen fastgjort ledeskovlkrans 6 og en turbineskive 4, 6 som på indersiden af en på tegningen opadrettet væg 27 7 bærer en løbeskovlkrans 22. Turbineskiven 4 er drejeligt 8 lejret på bærepladen 3 ved hjælp af en lejenitte 5 og en 9 mellem bærepladen og turbineskiven indlagt lejeskive 12.The Francis turbine consists of a support plate 3, which is suspended 3 between the two housing parts 1 and 8, which at this point are 4 mutually sealed by means of an O-ring 2, a guide vane ring 6 mounted on the support plate and a turbine disk 4, 6 which carries on the inside of a wall 27 7 upwardly in the drawing a running bucket ring 22. The turbine disk 4 is pivotally 8 mounted on the support plate 3 by means of a bearing rivet 5 and a 9 between the carrier plate and the turbine disk inserted bearing disk 12.

Under driften strømmer væsken ind gennem væsketiIførsels- 11 åbningen 17, gennem et antal åbninger 24 i bærepladen 3, DK 166437 B1 4 derpå gennem ledeskovlkransen 6 og rammer fra dennes udløb løbeskovlkransen 22, hvorpå væsken fortsætter imod udløbet, hvortil den eneste mulige vej er gennem dyse-5 bæreren 10. Det af dysebæreren 10 og excentermedbringeren 7 bestående aggregat styres til bevægelse om oscillationsaksen 20 af et i husets udløbsdel 8 anbragt styr 11, og når turbinen roterer, vil excenteren 21 bringe det nævnte aggregat til at oscillere om aksen 20 mellem den på 10 tegningen viste yderstilling og en tilsvarende, modsat beliggende yderstilling.During operation, the liquid flows in through the liquid feed opening 17, through a number of openings 24 in the carrier plate 3, thereafter through the guide vane ring 6 and strikes from its outlet the running vane ring 22, whereupon the liquid proceeds towards the outlet, to which the only possible path is through. the nozzle carrier 10. The assembly of the nozzle carrier 10 and the eccentric carrier 7 is guided to move about the oscillation axis 20 by a guide 11 located in the outlet portion 8 of the housing, and as the turbine rotates, the eccentric 21 causes the aggregate to oscillate about the axis 20 between the outer position shown in the 10 drawing and a correspondingly opposite outer position.

Med henblik på at begrænse turbinens hastighed og dermed bl.a. nedsætte slidet på de indbyrdes bevægelige dele er der mellem turbinerotorens ydervæg 27 og den overfor 15 liggende del af husets udløbsdel 8 dannet en smal bremse-spalte 13. De vægdele, der støder op til bremsespalten 13, kan være udstyret med ribber eller fordybninger med henblik på forøgelse af bremsevirkningen.With a view to limiting the speed of the turbine To reduce the wear on the mutually moving parts, a narrow brake gap 13 is formed between the outer wall 27 of the turbine rotor and the opposite part of the outlet portion 8 of the housing. The wall parts adjacent to the brake gap 13 may be provided with ribs or depressions for the purpose of on increasing the braking effect.

I det ringformede leje- og tætningslegeme 9 er der i det 20 viste udførelseseksempel udformet en ringformet rende 15, der opdeler leje- og tætnings fladen 26, 30 i en indre del 26 og en ydre del 30. Renden 15 er gennem en eller flere ikke viste kanaler forbundet med dysehusets indre, hvorved kun den radialt indre del 26 af leje- og tætningsfladen 25 virker som egentlig tætningsflade. Hensigten hermed er at undgå, at tætningsfladens areal forøges væsentligt efterhånden som leje- og tætningslegemet 9 nedslides under drift.In the annular bearing and sealing body 9, in the embodiment shown 20, an annular gutter 15 is formed which divides the bearing and sealing surface 26, 30 into an inner part 26 and an outer part 30. The gutter 15 is through one or more shown channels connected to the interior of the nozzle housing, whereby only the radially inner portion 26 of the bearing and sealing surface 25 acts as the actual sealing surface. The purpose of this is to prevent the area of the sealing surface from increasing substantially as the bearing and sealing body 9 is worn down during operation.

Når den viste dyse skal åbnes med henblik på eftersyn og 30 eventuel reparation, er det i første omgang tilstrækkeligt at skrue udløbsdelen 8 ud af indløbsdelen 1, hvad der passende kan ske ved hjælp af to dertil indrettede nøgler, f.eks. gaffelnøgler, der indgriber med ikke viste nøgleflader på de to husdele. Når udløbsdelen 8 skrues ud af 35 indløbsdelen 1, bringes excentermedbringeren 7 uden videre DK 166437 Bl 5 ud af indgreb med excenteren 21, og hele turbinen inklusive bærepladen 3 kan udtages fra indløbsdelen 1. Efter frigøring af fjederen 14 fra excentermedbringeren 7 kan 5 sidstnævnte udtages fra husets udløbsdel 8, og med den viste udformning af excentermedbringeren 7 og dysebæreren 10 kan sidstnævnte være løst indsat i excentermedbringeren 7 og derved være udskiftelig. Samtidigt hermed kan leje-og tætningslegemet 9 udskiftes, idet det ikke behøver at 10 være fastgjort i husets udløbsdel 8, hvor det normalt holdes på plads af fjederen 14.When the nozzle shown is to be opened for inspection and any repair, it is initially sufficient to unscrew the outlet portion 8 from the inlet portion 1, which may conveniently be done by means of two keys provided therefor, e.g. fork wrenches that engage with key faces not shown on the two housing parts. When the outlet portion 8 is unscrewed from the inlet portion 1, the eccentric 7 is readily brought out of engagement with the eccentric 21 and the entire turbine including the carrier plate 3 can be removed from the inlet portion 1. After release of the spring 14 from the eccentric 7, the latter 5 can be removed. from the outlet portion 8 of the housing, and with the shown design of the eccentric carrier 7 and the nozzle carrier 10, the latter can be loosely inserted into the eccentric carrier 7 and thereby be interchangeable. At the same time, the bearing and sealing body 9 can be replaced, since it does not need to be 10 fixed in the outlet part 8 of the housing, where it is usually held in place by the spring 14.

Dersom man ønsker at ændre den vinkel, som den udsprøjtede væskestråle gennemstryger, kan dette på enkel måde ske ved at udskifte turbinen med en anden turbine, hvis excenter 15 21 har en anden excentricitet. Svarende hertil kan for skellige turbiner også være udformet med henblik på en forskellig bredde af bremsespalten 13 eller forskellige udformninger af ydersiden af væggen 27, eller også forskellige udformninger af turbinens øvrige dele, såsom 20 ledeskovlkransen 6 og den roterende løbeskovlkrans 22. Selve udskiftningen kan udføres hurtigt af teknisk uøvet personale.If one wishes to change the angle that the extruded liquid jet extends, this can be done simply by replacing the turbine with another turbine whose eccentric 15 21 has a different eccentricity. Similarly, different turbines may also be designed for a different width of the brake gap 13 or different designs of the outside of the wall 27, or also different designs of the other parts of the turbine, such as the 20 bucket rim 6 and the rotary running bucket rim 22. The replacement itself can be carried out. quickly by technically trained personnel.
