Den foreliggende opfindelse angår et luftspredeelement, en såkaldt dysekrans, til anbringelse ved den nedre ende af et loftmonteret, nedadførende indblæsningsrør i et staldrum eller en lignende lokalitet, hvor ventilations-5 luft fra et eller flere sådanne rør ønskes spredt udover et i forhold til rørtværsnittet stort gulvareal. Det er herved sædvanligt, at en på rørenden monteret dysekrans lukker røret i nedadgående retning, men lader luften strømme ud gennem et antal radialstillede dyseåbninger, 10 der i stjerneform danner udragende dysekanaler hver med lodrette, parallelle sideflader, idet disse kanaler ved og med deres indre munding støder sideværts op til hinanden langs en cylinderflade, der i hovedsagen svarer til nedblæsningsrørets indre cylinderflade. Dysekanalerne ra-15 ger et stykke udad fra denne cylinderflade, således at de set i omkredsretningen har deres ydre mundinger beliggende med indbyrdes afstand, med trekantede blinde områder mellem nabodysekanalerne.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air diffuser element, a so-called nozzle ring, for positioning at the lower end of a ceiling-mounted downward supply air blower in a shed room or similar location where ventilation air from one or more such pipes is desired to be spread beyond a pipe cross section. large floor area. It is hereby customary that a nozzle rim mounted on the pipe end closes the pipe in a downward direction, but allows the air to flow through a number of radially positioned nozzle openings 10, which in star form form protruding nozzle channels each with vertical, parallel side faces, these channels at and with their interiors. orifice adjacent laterally to one another along a cylinder surface substantially similar to the inner cylinder surface of the blower tube. The nozzle channels extend outwardly from this cylinder surface so that, as seen in the circumferential direction, their outer orifices are spaced apart, with triangular blind areas between the adjacent nozzle channels.
I flere kendte udførelser af sådanne dysekranse er der dan-20 net en plan bund og et plant loft i dysekanalerne ved hjælp af et par svingplader, der ved de indre ender af kanalerne er svingeligt fastgjort omkring vandrette akser imellem de modstående, planparallelle kanalsider og strækker sig udad imellem disse, således at pladerne ved individuel 25 indstilling kan retningsbestemme forløbet i lodret retning af henholdsvis oversiden og undersiden af den luftstråle, der forlader dysekransen gennem den enkelte åbning. Man kan herved påvirke luftstrålen til at være således opad-eller nedadsøgende, eventuelt på konvergerende eller di-30 vergerende måde ud gennem dysen, at luftstrålen får en ønsket udbredelsesform, i hvert fald i grove træk. F.eks. alt efter hvor tæt ved hinanden, flere nedblæsningsrør er monteret, kan det være ønskeligt, at luftstrålerne søges kastet mere eller mindre langt ud, og yderligere 35 er det principielt ønskværdigt, at luften udkastes på en sådan måde, at den ikke hele vejen optræder som en koncen- 151055 2 treret stråle, der havner ved et forholdsvis lille gulv-område i betragtelig afstand fra nedblæsningsrørets akse; luften skal helst fordeles rimeligt jævnt over gulvet, og det er da også klart, at der fra en udsendt luftstråle 5 vil udtræde luft til den omliggende rumluft, således at der vil foregå en vis lufttilførsel til gulvet ud langs hele strålebanen, omend fortsat med kraftigst virkning ved den naturlige afslutning af luftstrålen.In several known embodiments of such nozzle wreaths, a flat bottom and a flat ceiling are formed in the nozzle channels by means of a pair of pivot plates which are pivotally attached at the inner ends of the channels between horizontal axes between the opposing, plane parallel channel sides and extensions. extend outwardly between these, so that the plates can individually direct the course in the vertical direction of the upper and lower sides of the air jet leaving the nozzle through the individual opening, respectively. One can thereby influence the air jet to be so upward or downward looking, possibly in a converging or divergent manner through the nozzle, that the air jet is given a desired propagation shape, at least in rough features. Eg. depending on how close to each other, several blowout pipes are mounted, it may be desirable that the air jets be sought to be thrown more or less far out, and further it is in principle desirable that the air be ejected in such a way that it does not appear all the way as a concentrated beam which terminates at a relatively small floor area at a considerable distance from the axis of the blow-off pipe; The air should preferably be distributed reasonably evenly over the floor, and it is then also clear that from an emitted air jet 5, air will escape to the surrounding room air, so that some air supply to the floor will take place along the entire beam path, albeit with the strongest effect at the natural termination of the air jet.
Opfindelsen bygger primært på den erkendelse, at det for 10 en virkelig god luftfordeling, f.eks. i kyllingehuse, ikke er tilstrækkeligt at forlade sig på, at luftstrålerne fra dyserne vil blande sig så effektivt med rumluften, at lufttilførslen til gulvet bliver blot tilnærmelsesvis ensartet i hele gulvventilationsområdet for det enkelte ned-15 blæsningsrør. Man kunne så drage omsorg for, at luftstrålerne f.eks. ved brug af flere luftledeplader blev spredt set i lodret plan, men dette ville være en teknisk kompliceret løsning, og tilbage bliver det problem, at strålerne udpræget udgår stjerneagtigt fra dysekanalerne, hvorved 20 der imellem nabostrålerne optræder markante trekantområder eller blinde vinkler, som ikke tilgodeses med nogen luftudstråling fra dysekransen. Også dette problem kunne muligvis afhjælpes ved brug af særlige luftledeplader for dele af luftstrålerne, men af forskellige grunde må en 25 sådan forlods betegnes som uhensigtsmæssig.The invention is primarily based on the recognition that for a really good air distribution, e.g. in chicken houses, it is not enough to rely on the air jets from the nozzles to blend so effectively with the room air that the air supply to the floor is only approximately uniform throughout the entire floor ventilation area of the individual blowout pipe. One could then make sure that the air jets, for example. using multiple air baffles was scattered seen vertically, but this would be a technically complicated solution, and again the problem becomes that the jets emanate star-like from the nozzle channels, where 20 between the neighboring jets appear marked triangular areas or blind angles that are not taken into account with any air radiation from the nozzle rim. Also, this problem could possibly be remedied by the use of special air baffles for parts of the air jets, but for various reasons such a loss must be considered inappropriate.
Det er på denne baggrund opfindelsens formål at angive et luftspredeelement eller en dysekrans af den nævnte art, som ved en ganske enkel udformning er i stand til at udvirke en mere ensartet luftudspredning end hidtil kendt.It is, therefore, the object of the invention to provide an air diffuser element or nozzle wreath of the aforementioned kind which, in a very simple design, is capable of effecting a more uniform air spread than previously known.
30 Dette opnås ifølge opfindelsen ved, at dysekanalerne er åbne opefter, og at overkanterne af deres sidevægge forløber udad-nedad-skrånende fra de indre åbninger af dysekanalerne. Den udblæste luftstrøm fra hver kanal vil herved foroven strømme udad uden nogen vægadskillelse fra 3 151055 den rumluft, der befinder sig i trekantområderne eller de blinde vinkler mellem den betragtede dyse og de tilstødende to nabodyser, og da luftstrålen har sin højeste lufthastighed netop vinder passagen af selve dysekanalen, 5 vil den herved fremkalde en udadgående påvirkning på rumluften i de nævnte trekantområder. Denne påvirkning vil aftage ind mod midten af trekantområderne, og resultatet vil være, at rumluften i disse områder vil medrives af luftstrålen gennem dysekanalen og af luftstråler-10 ne gennem dennes nabokanaler på en sådan måde, at rumluften vil udsendes som en luftstråle med svækket og endda gradueret hastighed i eller fra trekantområdet mellem hvert par af dysekanaler eller med andre ord, at der uden brug af særlige luftledeplader vil frembringes svagere, udad-15 rettede luftstrømme, der føres mod gulvet dels inden for nedslagsområderne for de koncentrerede dyseluftstråler og dels i trekantmellemrummene mellem disse stråler, dvs. med den betragtede indblanding af rumluft i de udsendte stråler vil der totalt opnås en langt mere ensartet luft-20 fordeling end ved de kendte anlæg, uden at der kræves nogen form for særlige luftledeplader.This is achieved according to the invention in that the nozzle channels are open upwards and that the upper edges of their side walls extend outwardly downwards from the inner openings of the nozzle channels. The exhaust air flow from each duct will hereby flow outward without any separation of wall from the room air located in the triangular areas or the blind angles between the considered nozzle and the adjacent two neighboring nozzles, and since the air jet has its highest air velocity, the passage of in this way, it will cause an outward influence on the room air in said triangular areas. This effect will decrease towards the center of the triangular regions and the result will be that the room air in these areas will be entrained by the air jet through the nozzle duct and by the air jets through its neighboring channels in such a way that the room air will be emitted as an attenuated air jet. even graduated velocity in or from the triangular region between each pair of nozzle ducts, or in other words, without the use of special air baffles, weaker, outward air flows will be produced which are directed towards the floor within the impact areas of the concentrated nozzle air jets and partly in the triangular spaces. between these rays, viz. with the considered admixture of room air in the emitted rays, a much more uniform air distribution will be achieved in total than at the known plants, without requiring any special air ducting.
Det er ved udviklingen af opfindelsen konstateret, at der reelt ikke er noget behov for overhovedet at benytte indstillelige bund- og loftplader i dysekanalerne, idet bun-25 den af kanalerne kan være en fast bundvæg, medens der slet ikke er behov for nogen særlig loftplade, da jo kanalerne fortrinsvis bør være helt åbne opefter. Dette betinger en yderligere forenklet udførelse af dysekransen ifølge opfindelsen.It has been found in the development of the invention that there is really no need at all to use adjustable bottom and ceiling plates in the nozzle ducts, the bottom of the ducts being a fixed bottom wall, while no special ceiling plate is needed at all. since the channels should preferably be completely open upwards. This requires a further simplified embodiment of the nozzle rim according to the invention.
30 Det skal bemærkes, at det er kendt at anbringe et konisk luftspredelegeme nede under mundingen af et lodret ind-blæsningsrør, hvorved luften kan spredes tilsvarende jævnt omkring udløbet. En sådan jævn spredning gennem et ubrudt rundtgående dyseområde giver dog en langt mindre 35 aktionsradius end ved brug af en egentlig dysekrans, hvor 4 151055 indføringsluften er koncentreret i radiale luftstråler.It should be noted that it is known to place a tapered air-spraying body below the mouth of a vertical blow-in pipe, whereby the air can be distributed equally evenly around the outlet. However, such an even spread through an unbroken orbital nozzle area provides a much smaller radius of action than using an actual nozzle wreath, where the inlet air is concentrated in radial air jets.
Fra tysk offentliggørelsesskrift nr. 27 18 298 er det yderligere kendt, at der på det koniske spredelegeme kan være anbragt luftlederibber, som meddeler den nedad-udad-5 strømmende luft en omdrejende bevægelse, men dette ændrer ikke ved det forhold, at luften spredes på jævn måde og ikke gennem koncentrerede stråler med stor aktionslængde som ved brug af en dysekrans.From German Publication No. 27 18 298 it is further known that air conduit ribs may be arranged on the conical diffuser body which give the downwardly outward-flowing air a revolving motion, but this does not change the fact that the air is spread on smoothly and not through concentrated rays of great action length as if using a nozzle.
Opfindelsen forklares i det følgende nærmere i forbindelse 10 med tegningen, på hvilken fig. 1 er et sidebillede af en dysekrans ifølge opfindelsen, og fig. 2 et snitbillede af samme.The invention will now be explained in more detail in connection with the drawing, in which FIG. 1 is a side view of a nozzle wreath according to the invention; and FIG. 2 is a sectional view of the same.
Den viste dysekrans 2 er anbragt på den nedre ende af et 15 nedblæsningsrør 4, der er monteret nedragende fra og gennem taget af f.eks. et kyllingehus, hvori der kan forekomme flere sådanne nedblæsningsrør. Som vist i fig. 2 tjener dysekransen tillige som holder for en motor 6 til drift af en ventilatorvinge 8, som trækker friskluft ned gennem 20 røret 4.The shown nozzle ring 2 is arranged on the lower end of a blowout pipe 4 mounted downwardly from and through the roof of e.g. a chicken house in which several such blow-off pipes may be present. As shown in FIG. 2, the nozzle wreath also serves as a holder for a motor 6 for operating a fan blade 8 which draws fresh air down through the pipe 4.
Dysekransen er fortrinsvis støbt i ét stykke i et egnet fast skummateriale, der øverst er tilsluttet en monteringsring 10 og i øvrigt opviser et antal sideåbninger 12. I området lige under røret 4 har dysekransen en konisk bundpla-25 dedel 14, som fortsætter ud gennem sideåbningerne 12, hvor den danner en bund 16 i en fra hver sideåbning 12 udstående dysekanal 18. Hver af disse kanaler udgøres af en åben rende, hvis bund 16 ved siderne overgår i lodrette og i hovedsagen parallelle sidevægge 20. I de herved fremkomne 30 trekantformede områder mellem de mod hinanden vendende sidevægge 20 af hvert par af nabodysekanaler 18 er disse sidevægge ved deres overkanter indbyrdes forbundet ved hjælp af tilsvarende trekantede overplader 22, som er til- 5 151055 dannet i ét stykke med sidevæggene 20. Disse sidevægges overkanter og dermed overplademe 22 forløber udpræget faldende udefter fra nedblæsningsrøret, og de ydre hjørneområder mellem sidevæggene og overpladerne er afrundede 5 som vist ved 24.The nozzle rim is preferably one-piece molded into a suitable solid foam material which is connected to the top of a mounting ring 10 and otherwise has a number of side openings 12. In the area just below the tube 4, the nozzle rim has a tapered bottom plate portion 14 which extends out through the side openings. 12, where it forms a base 16 in a nozzle channel 18 projecting from each side aperture 12. Each of these channels is constituted by an open channel whose bottom 16 at the sides transitions into vertical and generally parallel side walls 20. In the resulting triangular regions between the facing side walls 20 of each pair of neighboring nozzle channels 18, these side walls at their upper edges are interconnected by corresponding triangular tops 22 which are integrally formed with the side walls 20. These upper walls and thus the tops 22 the protrusion extends outwardly from the blowpipe, and the outer corner regions between the side walls and the top plates are rounded 5 as shown at 24 .
Lige inden for sideåbningerne 12 er der som vist i fig. 2 udformet en rundtgående vandopsamlingsrende 26 i bundpla-dedelen 14.Just within the side openings 12, as shown in FIG. 2, a circumferential water collecting duct 26 is formed in the bottom plate portion 14.
Når ventilatoren 6,8 arbejder, vil luften trækkes ned gen-10 nem røret 4 og udsendes radialt gennem dysekanalerne 18, idet luften udledes langs den koniske, yderst udfladende bund 14,16. Det vil være muligt at benytte svingbare ledeplader i stedet for eller lige ovenover kanalbundene 16, hvorved den udstrålede luft kan styres mere eller mindre 15 opad eller nedad. Det er dog konstateret, at det i næsten alle tilfælde - og navnlig ved dysekransen ifølge opfindelsen i øvrigt - vil være tilstrækkeligt at arbejde med en fast bund 16 i dysekanalerne, når denne yderst ved sin udmunding forløber helt eller næsten helt vandret, hvilket 20 normalt vil give den mest hensigtsmæssige spredning af luften.As the fan 6.8 operates, the air will be drawn down through the tube 4 and radially discharged through the nozzle ducts 18, the air being discharged along the conical, highly flattened bottom 14, 16. It will be possible to use pivotable baffles instead of or just above the channel bottoms 16, whereby the radiated air can be controlled more or less upwards or downwards. However, it has been found that in almost all cases - and especially at the nozzle rim according to the invention in general - it will be sufficient to work with a fixed bottom 16 in the nozzle channels when the latter extends completely or almost completely horizontally, which normally will provide the most appropriate spread of air.
Som vist med pile a i fig. 2 vil den øvre del af luftud-strålingen gennem hver dysekanal 18 krydse det nedadgående forløb af overpladerne 22 og altså udtræde i fri luft alle-25 rede inden den når frem til den ydre ende af dysekanalen.As shown by arrows a in FIG. 2, the upper portion of the air radiation through each nozzle channel 18 will traverse the downward course of the top plates 22 and thus exit into free air already before reaching the outer end of the nozzle channel.
Ved denne udtrædning vil rumluften oven over overpladerne 22 påvirkes til medrivning udefter, således som det er . antydet med punkterede pile b i fig. 2. Denne virkning forstærkes af, at noget af selve den udblæste luft øverst 30 i strålen kan udstråles vifteformet, fordi den kun over en kort strækning styres udad i rummet mellem de parallelle sidevægge 20.Upon this exit, the room air above the top plates 22 will be affected for entrainment outwards, as is. indicated by dotted arrows b in FIG. 2. This effect is enhanced by the fact that some of the blown air itself at the top 30 of the jet can be radiated fan-shaped because it is only directed outwards in the space between the parallel side walls 20.
Den luft, som herved i betragtelig mængde vil strømme udad fra de trekantede områder over overpladerne 22, vil na- 6 151055 turligvis udstrømme med betydeligt mindre hastighed end de koncentrerede stråler fra dysekanalerne, dog med øget hastighed i nærheden af disse stråler. Da denne langsomme luft udtræder i de ydre trekantområder imellem de krafti-5 ge luftstråler, vil den langsomme luft optræde som selvstændige, svagere stråler, der vil fordele luften ganske effektivt over gulvarealet inden for det område, hvor luftstrålerne fra dysekanalerne 18 når gulvet. Det er klart, at der ikke herved er tale om skarpt afgrænsede 10 områder, men resultatet vil alligevel være en stærkt forbedret jævnhed i luftfordelingen over hele det betragtede areal.The air which will thereby flow substantially outward from the triangular areas above the surface plates 22 will, of course, flow out at considerably less velocity than the concentrated jets of the nozzle channels, however, with increased velocity in the vicinity of these rays. As this slow air exits in the outer triangular regions between the powerful air jets, the slow air will act as independent, weaker jets that will distribute the air quite effectively over the floor area within the area where the air jets from the nozzle ducts 18 reach the floor. Obviously, this is not a case of sharply delineated 10 areas, but the result will nevertheless be a greatly improved uniformity of air distribution throughout the area considered.
Med den viste udførelse af dysekransen er ved forsøg konstateret en meget høj nyttevirkning, hvilket formentlig er 15 delvis begrundet af, at der er tale om en formgivning, som kian giver anledning til ringe turbulens.With the illustrated design of the nozzle wreath a very high utility effect has been found in experiments, which is probably partly due to the fact that it is a design which causes low turbulence.
Der er ved opfindelsen ikke konstateret noget behov for brug af særlige ledeplader ovenover dysekanalerne 18.No need has been found in the invention for the use of special baffles over the nozzle channels 18.
I øvrigt udmærker den viste dysekrans sig ved, at den for 20 hovedpartens vedkommende let kan fremstilles ved støbning i ét enkelt stykke.Moreover, the nozzle ring shown is distinguished by the fact that for the majority of it it can be easily manufactured by a single piece molding.
