Description

Den foreliggende oppfinnelse vedrører en anordning av den i innledningen i krav 1 angitte art. The present invention relates to a device of the kind specified in the introduction in claim 1.

Fra norsk utlegningsskrift 163 64 9 er det kjent en lokkan-ordning for lastbeholdere hvor det finnes én eller flere beholdere for kjøle- eller frysemedium, nærmere bestemt flytende nitrogen eller lignende lavtemperaturmedium. Beholderne er utstyrt med ut løpsledninger som er innrettet slik at de stadig er åpne mot rommet som kjøles, noe som innebærer at medium i gassform strømmer ut fra beholderen så snart denne er fylt. Den foreliggende oppfinnelse bygger på samme grunnidé, at det for et rom som skal holdes på lav temperatur anordnes én eller flere påfyll-bare beholdere hvorfra det temperatursenkende medium i gassform fritt strømmer inn i rommet. From Norwegian design document 163 64 9, a lokkan arrangement is known for cargo containers where there are one or more containers for cooling or freezing medium, more precisely liquid nitrogen or similar low-temperature medium. The containers are equipped with outlet lines that are arranged so that they are constantly open to the room being cooled, which means that medium in gaseous form flows out of the container as soon as it is filled. The present invention is based on the same basic idea, that for a room to be kept at a low temperature, one or more refillable containers are arranged from which the temperature-lowering medium in gaseous form flows freely into the room.

I DE 1 501 297 er det vist en beholder som i sin bunn er utstyrt med en detektor. For å hindre at kryogen skal nå hen til detektoren er det over detektoren anordnet en liten mengde porøst materiale. DE 1 501 297 shows a container which is equipped with a detector at its bottom. To prevent cryogen from reaching the detector, a small amount of porous material is arranged above the detector.

Medium av den aktuelle type, dvs. flytende nitrogen og lignende kan innebære visse risikoer ved håndteringen dersom skvett av flytende medium kommer på ubeskyttet hud. Ved lokkan-ordninger av den innledningsvis angitte type er risikoen elimi-nert ved at påfylling av beholderne foregår først når lokket er lagt på plass over lastbeholderen. Når det gjelder løse kjøle-mediumbeholdere som plasseres i lastbeholderen og rommet etter at de er fylt, vil en uforsiktig håndtering imidlertid kunne medføre slike risikoer. Medium of the type in question, i.e. liquid nitrogen and the like, can involve certain risks when handling if splashes of liquid medium get on unprotected skin. In lidkan arrangements of the type indicated at the outset, the risk is eliminated by filling the containers only when the lid has been put in place over the cargo container. However, in the case of loose refrigerant containers that are placed in the cargo container and compartment after they have been filled, careless handling could lead to such risks.

Formålet med den foreliggende oppfinnelse er å frembringe en anordning som eliminerer risikoen for at flytende kjøle- eller frysemedium skal komme løst, skvette eller på annen måte skade den håndterende person. The purpose of the present invention is to produce a device which eliminates the risk of liquid cooling or freezing medium coming loose, splashing or otherwise damaging the person handling it.

Det som kjennetegner anordningen ifølge oppfinnelsen er an-gitt i patentkravene. What characterizes the device according to the invention is stated in the patent claims.

Et utførelseseksempel på anordningen ifølge oppfinnelsen vil bli nærmere beskrevet i det etterfølgende under henvisning den medfølgende tegning, hvor: Fig. 1 viser et skjematisk langsgående snitt gjennom en beholder anordnet ifølge oppfinnelsen. An embodiment of the device according to the invention will be described in more detail below with reference to the accompanying drawing, where: Fig. 1 shows a schematic longitudinal section through a container arranged according to the invention.

Fig. 2 viser beholderen sett fra den ene ende. Fig. 2 shows the container seen from one end.

Fig. 3 viser et snitt etter linjen A-A i fig. 1. Fig. 3 shows a section along the line A-A in fig. 1.

Fig. 4 viser det høyre endeparti av fig. 1 i komplett til-stand. Fig. 5 viser et påfyllingsorgan tilpasset til anordningen. Fig. 4 shows the right end part of fig. 1 in complete condition. Fig. 5 shows a filling device adapted to the device.

Selve beholderen er betegnet med henvisningstall 1 og har en sylindrisk kappe og til denne fastsveisede, lett innadbuktede gavler 2 respektivt 3. Beholderen kan ha relativt tynne vegger idet den ikke er en trykkbeholder. Beholderen er anbrakt i et ytre hylster 4 med plane gavler 5 respektivt 6, og et rom eller beholderen 1 og det ytre hylster 4 er helt fylt med isolerings-materiale av skumplast, f.eks. polyuretan. Henvisningstall 8 be-tegner et rør som anvendes ved skummingen. Beholderen 1 er fylt med et skvalpehindrende materiale med ullaktig struktur, hensiktsmessig et materiale som finnes under handelsnavnet The container itself is denoted by the reference number 1 and has a cylindrical shell and to this welded, slightly inwardly curved ends 2 and 3 respectively. The container can have relatively thin walls as it is not a pressure container. The container is placed in an outer sleeve 4 with flat ends 5 and 6 respectively, and a room or the container 1 and the outer sleeve 4 are completely filled with insulating material made of foam plastic, e.g. polyurethane. Reference number 8 denotes a tube used for foaming. The container 1 is filled with an anti-flutter material with a wool-like structure, suitably a material found under the trade name

"KAOWOOL". "KAOWOOL".

Gjennom den ene gavl 2 rager det to rør. Det ene rør 10 er et påfyllingsrør, og dette går inne i beholderen 1 over i en hylse 11 med nett- eller gitterstruktur. Hylsen 11 er anordnet for å hindre at ullmaterialet 9 ved påfylling av flytende medium skal deformeres og for å danne en fri passasje fra røret 10 bort mot den motsatte gavl 3. Two pipes protrude through one gable 2. The one tube 10 is a filling tube, and this goes inside the container 1 into a sleeve 11 with a net or lattice structure. The sleeve 11 is arranged to prevent the wool material 9 from being deformed when filled with liquid medium and to form a free passage from the pipe 10 away towards the opposite end 3.

På røret 10 er som det fremgår av fig. 4 en koplingsdel 12 i bruksstilling utstyrt med et lokk 13, som er utstyrt med et så-kalt sprengblikk, som skal gi etter dersom det av utilsiktet år-sak stadig åpne utløp skulle bli tilstoppet slik at trykket i beholderen øker ved fordampning. On the pipe 10, as can be seen from fig. 4, a coupling part 12 in the use position equipped with a lid 13, which is equipped with a so-called bursting valve, which must give way if the constantly open outlet should accidentally become blocked so that the pressure in the container increases due to evaporation.

Det andre rør 14 som er anordnet ved gavlen 2 funksjonerer som utløp for fordampet medium og er som det fremgår av fig. 4 koplet til en ledning 15 til munnstykkene, ikke viste, som munner ut i transportrommet. Mellom ledningen 15, og røret 8 som utelukkende anvendes ved skummingen, er det festet et blindt rør-stykke 16 for å stabilisere ledningen 15 slik at denne kan anvendes som bærehåndtak. For å eliminere risikoen for at regn eller vanndråper skal kunne komme inn i røret 15 når tomme beholdere lagres utendørs er røret 15 nedadrettet. Rundt røret 15 er det anordnet en ikke vist isolasjonshylse. The second pipe 14 which is arranged at the gable 2 functions as an outlet for evaporated medium and is, as can be seen from fig. 4 connected to a line 15 to the nozzles, not shown, which open into the transport space. Between the line 15 and the pipe 8 which is exclusively used for the foaming, a blind piece of pipe 16 is attached to stabilize the line 15 so that it can be used as a carrying handle. To eliminate the risk of rain or water droplets entering the tube 15 when empty containers are stored outdoors, the tube 15 is directed downwards. An insulating sleeve, not shown, is arranged around the pipe 15.

Utløpsrøret 14, som rager gjennom beholdergavlen og ytter-kappens gavl, er straks innenfor gavlen 2 utstyrt med et stort T-stykke 17 hvorfra et rørparti 18 fortsetter rettlinjet mot den bortre gavl 3 for der via et stort U-bøyet parti 19 å gå over i et rettlinjet rørparti 20, som har sin åpne innløpsende 21 omtrent i høyde med T-stykket 17. The outlet pipe 14, which protrudes through the container end and the end of the outer casing, is immediately inside the end 2 equipped with a large T-piece 17 from which a pipe section 18 continues in a straight line towards the far end 3 to go over via a large U-bent section 19 in a straight pipe section 20, which has its open inlet end 21 approximately at the height of the T-piece 17.

Fra T-stykket 17 rager det et ytterligere rør 2 2 via et av-vinklet parti 23 bort mot den bortre gavl 3, hvor det har sin åpne innløpsende 24. Utløpsrøret 14 og derved ledningen 15 står altså i forbindelse med beholderens indre via de to åpninger 21 og 24, som befinner seg inntil hver sin ende av beholderen 1. Risiko for at flytende medium skal presses ut gjennom gassutløps-røret i en beholder av den aktuelle type oppstår når utløpsrørets innløpsende kommer under væskeflaten og gass innelukkes i rommet ovenfor denne. Så lenge beholderen 1 befinner seg i sin hori-sontale bruksstilling, finnes det selv om det fantes en eneste innløpsåpning plassert i beholderens øvre parti ingen risiko for utstrømming av væske, idet røråpningen befinner seg helt ovenfor væskeflaten. Altså strømmer utelukkende gass ut gjennom røret 14. Ved håndtering av beholderen, dersom den bæres i den ene gavlende anordnete håndtak, ville det imidlertid når beholderen er fylt med væske foreligge risiko for at gassvolumet, som blir inne-stengt i beholderens da lukkede øvre parti, presses ut væske gjennom utløpsrøret. Dette hindres ved den løsning som er fore-slått her. From the T-piece 17, a further pipe 22 projects via an angled part 23 towards the far end 3, where it has its open inlet end 24. The outlet pipe 14 and thereby the line 15 are thus connected to the inside of the container via the two openings 21 and 24, which are located next to each end of the container 1. The risk of liquid medium being forced out through the gas outlet pipe in a container of the type in question occurs when the inlet end of the outlet pipe comes below the liquid surface and gas is trapped in the space above this. As long as the container 1 is in its horizontal position of use, even if there was a single inlet opening located in the upper part of the container, there is no risk of outflow of liquid, as the pipe opening is located completely above the liquid surface. In other words, only gas flows out through the tube 14. When handling the container, if it is carried by the one gabled handle, however, when the container is filled with liquid, there would be a risk that the volume of gas, which is trapped in the then closed upper part of the container , liquid is forced out through the outlet pipe. This is prevented by the solution proposed here.

Uansett hvilken ende av beholderen som vendes oppad finnes det i det aktuelle oppadvendende parti av beholderen en fri rør-åpning 21 eller 24, hvorigjennom gass uhindret strømmer ut, slik at uønsket trykkoppbygging elimineres. Når beholderen bæres i det håndtakdannende rør 15, befinner åpningen 24 seg under væskeflaten, mens åpningen 21 er fri. Dersom under innsettingen av beholderen i transportrommet f.eks. den andre ende skulle komme lavere, blir åpningen 24 dekket av væske, mens åpningen 21 er fri. Rørsløyfen 18, 19, 20 gjør at medium på grunn av selvrenning ikke kommer ut. Regardless of which end of the container is turned upwards, there is a free tube opening 21 or 24 in the respective upwards-facing part of the container, through which gas flows out unhindered, so that unwanted pressure build-up is eliminated. When the container is carried in the handle-forming tube 15, the opening 24 is below the liquid surface, while the opening 21 is free. If during the insertion of the container in the transport compartment, e.g. the other end should come lower, the opening 24 is covered by liquid, while the opening 21 is free. The pipe loop 18, 19, 20 means that the medium does not escape due to self-flow.

På ytterhylsteret 4 er det anordnet bæreører eller -skinner 2 5, hvormed beholderen henges opp og skyves inn i lasterommet. Beholderen skal således befinne seg horisontalt i bruksstilling, mens den ved påfylling og under oppbevaring står på gaffelen 6, som fortrinnsvis er utstyrt med hensiktsmessig beskyttelse, slik at håndtaket 15 vender oppad. Carrying lugs or rails 25 are arranged on the outer casing 4, with which the container is suspended and pushed into the cargo space. The container must therefore be horizontally in the position of use, while when filling and during storage it stands on the fork 6, which is preferably equipped with appropriate protection, so that the handle 15 faces upwards.

Påfyllingen foregår ved hjelp av et påfyllingsorgan 26, som er vist i fig. 5 og som omfatter et påfyllingsrør 27, som ved hjelp av slange eller lignende 28 er forbundet med en beholder for flytende medium/nitrogen. Røret 27, som i sin frie ende har et endestykke, er betydelig tynnere enn tankens 1 påfyllingsrør 10 og hylsen 11 slik at det oppstår klaring av de to rør. The filling takes place by means of a filling device 26, which is shown in fig. 5 and which comprises a filling pipe 27, which is connected by means of a hose or the like 28 to a container for liquid medium/nitrogen. The pipe 27, which has an end piece at its free end, is considerably thinner than the tank 1 filling pipe 10 and the sleeve 11 so that clearance occurs between the two pipes.

Påfyllingsrøret 27 er festet til en koplingsdel 29 som er utformet på stort sett samme måte som det med sprengblikk ut-styrte lokk 13, med to eksenterlås innrettet til å danne inngrep med en rundtgående utsparing på en tilkoplingsnippel på koplingsdelen 12 som er festet til rørets 10 ende. Koplingsdelen 29 og lokket 13 har en pakning som danner tettende anlegg mot tilkop-1ingsnippelens ende. På koplingsdelen 29 er det også festet en kappe 30, som omslutter påfyllingsrøret 27 og som gjennom åpninger radialt innenfor pakningen står i forbindelse med rørets 10 indre. Kappen 3 0 er i sin bortre ende tett forbundet med påfylli-ngsrøret 27 og er utstyrt med et avløpsrør 31, som hensiktsmessig er sammenkoplet med en slange eller lignende 32. The filling pipe 27 is attached to a connecting part 29 which is designed in much the same way as the lid 13 equipped with a bursting plate, with two eccentric locks arranged to engage with a circumferential recess on a connecting nipple on the connecting part 12 which is attached to the pipe's 10 end. The coupling part 29 and the lid 13 have a seal which forms a sealing contact against the end of the connection nipple. A cover 30 is also attached to the connecting part 29, which encloses the filling tube 27 and which is in connection with the inside of the tube 10 through openings radially within the gasket. At its far end, the cap 30 is tightly connected to the filling pipe 27 and is equipped with a drain pipe 31, which is appropriately connected with a hose or the like 32.

Ved påfylling av flytende medium strømmer dette gjennom røret 27 inn i røret 10 og nett- eller gitterhylsen 11, fig. 1. Derved vil en del av mediet umiddelbart forgasses, og gassen kan da, foruten gjennom det ovenfor nevnte gassutløp 14, 15 også unn-slippe via klaringen rundt det i røret 10 og hylsen 11 innad-ragende parti av røret 27, passasjen ved koplingsdelen og kappen 30 til avløpet 31, 32. Derved kan påfyllingen foregå hurtig når i det mottrykk som er dannet ved forgassingen effektivt utjevnes. Når påfyllingen har foregått til ønsket nivå fjernes påfyllings-organet, og lokket 13 påsettes. When filling with liquid medium, this flows through the pipe 27 into the pipe 10 and the net or grid sleeve 11, fig. 1. Thereby, part of the medium will immediately gasify, and the gas can then, in addition to the above-mentioned gas outlet 14, 15, also escape via the clearance around the inwardly projecting part of the pipe 27 in the pipe 10 and the sleeve 11, the passage at the connecting part and the jacket 30 to the drain 31, 32. Thereby, the filling can take place quickly when the back pressure created by the gasification is effectively equalised. When the filling has taken place to the desired level, the filling device is removed, and the lid 13 is put on.

Av håndteringsmessige og praktiske årsaker skal beholderen, som under påfylling står på den ene gavl, bare fylles omtrent i høyde med den innløpsåpning 21 som befinner seg nærmest påfyl1-ingsrøret 10, hvorved det finnes rom og fritt utløp for gass som allerede under påfyllingen er fordampet. I den viste utførelses-form er et utløpsrørsystem, som er utstyrt med to innløpsåpninger 21 og 24, plassert eksentrisk i beholderen, hvorved det forut-settes at beholderen når den ikke oppbevares stående, skal vende med rørsystemet oppad. I en modifisert utførelsesform for beholdere hvor man ikke alltid kan være sikker på en slik stilling kan det i beholderen være anordnet én eller flere ytterligere grenledninger med innløpsåpninger som er innbyrdes atskilte langs omkretsen, slik at selv om beholderen skulle ligge og rulle en røråpning alltid befinner seg i et gassfylt rom. For handling and practical reasons, the container, which stands on one end during filling, should only be filled approximately to the height of the inlet opening 21 which is located closest to the filling pipe 10, whereby there is room and a free outlet for gas that has already evaporated during filling . In the embodiment shown, an outlet pipe system, which is equipped with two inlet openings 21 and 24, is placed eccentrically in the container, whereby it is assumed that the container, when it is not stored upright, should face the pipe system upwards. In a modified embodiment for containers where one cannot always be sure of such a position, one or more additional branch lines can be arranged in the container with inlet openings that are mutually separated along the circumference, so that even if the container were to lie and roll a pipe opening is always located themselves in a gas-filled room.
