Description

Luftgjennomtrengelig slange med innlegg. Air-permeable hose with inserts.

Oppfinnelsen vedrører en luftgjennomtrengelig slange for innføring av opp-hvirvlings- eller fluidiseringluft i støv- eller melformet gods. The invention relates to an air-permeable hose for introducing swirling or fluidizing air into dusty or mealy goods.

Det er tidligere kjent for transport av støv- eller melformet gods fra transport-beholdere, siloer, transportrenner e. 1., at godset gjøres lett flytende ved at opphvirvlingsluft tilføres gjennom slanger forsynt med luftgjennomtrengelig vegg, hvilke slanger fortrinnsvis anbringes i bølgedaler i en bølgeformig utformet bunn i transportbeholderen, siloen, transportkanalen e. 1. It is previously known for the transport of dusty or mealy goods from transport containers, silos, transport chutes, etc., that the goods are easily liquefied by introducing swirling air through hoses equipped with an air-permeable wall, which hoses are preferably placed in wave valleys in a wave-shaped designed bottom in the transport container, silo, transport channel e. 1.

Det er videre kjent i slike luftgjen-nomtrengelige slanger å anordne stive innlegg av rundt, rettvinklet eller ovalt tverrsnitt i den hensikt å hindre en fullstendig sammentrykning av slangen under vekten av støvgodset når tilførselen av opphvirvlingsluft til slangene avbrytes, slik at over hele slangens lengde opprettholdes luft-kanaler i hvilke opphvirvlingsluft uhindret kan strømme. It is also known in such air-permeable hoses to arrange rigid inserts of round, right-angled or oval cross-section in order to prevent a complete compression of the hose under the weight of the dust when the supply of swirling air to the hoses is interrupted, so that over the entire length of the hose is maintained air channels in which swirling air can flow unhindered.

Endelig er det også kjent å anordne et stivt innlegg i form av en skinne forsynt med langsgående ribber, idet skinnens bredde er noe mindre enn den halve slange-omkrets og dens høyde bare er en brøk-del av bredden, hvorved slangen holdes i tverrsnitt avflatet, idet denne anordning med sin bredde ikke vesentlig overskrider bølgedalene for den bølgeformig utformede bunn i transportbeholderen, siloen, transportkanalen e. 1. Finally, it is also known to arrange a rigid insert in the form of a rail provided with longitudinal ribs, the width of the rail being slightly less than half the hose circumference and its height only a fraction of the width, whereby the hose is kept flattened in cross-section , as this device with its width does not significantly exceed the wave valleys for the undulating bottom in the transport container, silo, transport channel e. 1.

Anvendelse av slike stive innlegg i Application of such rigid posts i

slanger vanskeliggjør innbygging i trans-portbeholdere, siloer, transportkanaler e.l. Likeledes blir også transporten åv' slangen hoses make it difficult to install in transport containers, silos, transport channels etc. In the same way, the transport is also done by the hose

vanskeliggjort, hvis da ikke innlegget føres inn først like før slangen skal legges ned. Selv i sistnevnte tilfelle frembyr imidler-tid transporten av innlegget vanskeligheter, særlig når dette p.g.a. anvendelse av lange slangestykker må ha en tilsvarende stor lengde. made difficult, if the insert is not inserted first just before the hose is to be laid down. Even in the latter case, however, the transport of the post presents difficulties, especially when this is due to the use of long pieces of hose must have a correspondingly large length.

Oppfinnelsen har til hensikt å unngå disse ulemper, og består i at der i slangen anordnes et innlegg bestående av flere i slangens lengderetning bevegelig forbundende ledd. The invention aims to avoid these disadvantages, and consists in arranging an insert in the hose consisting of several connecting joints which are movable in the lengthwise direction of the hose.

Anvendelse av et slikt leddet innlegg i slangen gjør at den kan rulles opp mens Application of such an articulated insert in the hose means that it can be rolled up while

innlegget befinner seg i slangen, slik at denne ved transport tar liten plass. Også innlegget av slangen f. eks. på bunnen av en transportbeholder, silo e. 1. blir derved lettere, da slangen i opprullet tilstand først kan føres inn gjennom mannhullet i transportbeholderen, siloen e.l., hvorpå den rulles opp i det indre av beholderen. the insert is located in the hose, so that it takes up little space during transport. Also the insertion of the snake e.g. on the bottom of a transport container, silo etc. 1. thereby becomes easier, as the coiled up hose can first be fed through the manhole in the transport container, silo etc., after which it is rolled up into the interior of the container.

En foretrukket utførelse av et slange-innlegg ifølge oppfinnelsen består i at dette innlegg dannes av på avstand fra hver-andre tvers på slangens lengderetning beliggende rørformede hylser, samt trådbøy-ler som forener disse hylser med hver-andre. A preferred embodiment of a hose insert according to the invention consists in this insert being formed by tubular sleeves situated at a distance from each other across the longitudinal direction of the hose, as well as wire hoops which unite these sleeves with each other.

I fig. 1 vises et lengdesnitt langs en slange som holdes flat ved hjelp av et innlegg, og In fig. 1 shows a longitudinal section along a hose that is held flat by means of an insert, and

fig. 2 er et tverrsnitt etter linjen II—II fig. 2 is a cross-section along the line II—II

i fig. 1. in fig. 1.

I den med luftgjennomtrengelig vegg utformede, fortrinnsvis vevede slange 1 er der innført på .en .viss innbyrdes avstand anbragte<;> tvers; på slangens lengderetning liggende rørformede hylser 2, som er innbyrdes forbundet ved hjelp av trådbøyler 3. Lengden av de rørformede hylser 2 er da slik tilpasset for å holde slangen flat at hylsene sammen med trådbøylene 3 har en bredde som er noe mindre enn halve slangens omkrets. Dimensjonene for nevnte rørformede hylser andrar bare til en brøk-del av innleggets bredde. Bredden av innlegget kan også være mindre, når det ikke er av viktighet at slangen holdes flat ved hjelp av innlegget. In the preferably woven hose 1, which is designed with an air-permeable wall, there are introduced at a certain distance from each other placed <;> transversely; tubular sleeves 2 lying along the length of the hose, which are interconnected by means of wire hangers 3. The length of the tubular sleeves 2 is then adapted to keep the hose flat so that the sleeves together with the wire hangers 3 have a width that is slightly less than half the circumference of the hose . The dimensions of said tubular sleeves only change to a fraction of the insert's width. The width of the insert can also be smaller, when it is not important that the hose is kept flat with the help of the insert.

Istedenfor det på tegningen viste og ovenfor beskrevne leddede innlegg, kan selvsagt også andre typer flate, leddede Innlegg komme til anvendelse, f. eks. slike innlegg som har form av flate kjeder e. 1., så lenge det mål oppnås at derved slangen med det i denne beliggende innlegg lar seg rulle opp. Instead of the articulated inserts shown in the drawing and described above, other types of flat, articulated inserts can of course also be used, e.g. such inserts that have the form of flat chains e. 1., as long as the goal is achieved that thereby the hose with the insert located in this insert can be rolled up.
