(54) Fremgangsmåde ved udfyldning af et rum med Isolerende, partikelformigt materiale samt apparat til udøvelse af fremgangsmåden.(54) Method of filling a compartment with Insulating particulate material and apparatus for carrying out the process.
Den foreliggende opfindelse angår en fremgangsmåde og et apparat til udfyldning af et rum, mere specielt et aflangt, rum, med isolerende, partikelformigt materiale, fortrinsvis mineraluld, som eventuelt er granuleret, og af den i indledningen til krav 1 angivne art.The present invention relates to a method and apparatus for filling a compartment, more particularly an elongated compartment, with insulating particulate material, preferably mineral wool which is optionally granulated, and of the kind specified in the preamble of claim 1.
® Anvendelsen af mineraluld, som eventuelt er granuleret, til varme- og/eller lydisolerende formål er kendtΓ Til dette for-cO mål kan mineralulden f.eks. formes til genstande såsom halve rør- formede dele til isolering af rørledninger.® The use of mineral wool, which may be granulated, for heat and / or sound-insulating purposes is known. formed into objects such as half tubular parts for insulation of pipelines.
Det er også kendt at dække en genstand og at opfylde det y resterende rum med mineraluld, som eventuelt kan være granuleret, O ved indblæsning af en gasstrøm i dette hulrum.It is also known to cover an object and to fill the y residue with mineral wool which may be granulated, O by blowing a gas stream into this cavity.

Udfyldning af aflange rum med relativt lille tværsnit er imidlertid meget vanskeligt som følge af, at de fremkomne luftstrømme vil bevirke en aflejring af mineraluldpartikleme med meget ringe homogenitet, således at den opnåede isolering lader meget tilbage at ønske.However, filling of elongated compartments of relatively small cross-section is very difficult as the resulting air streams will cause a deposition of the mineral wool particles with very low homogeneity, so that the insulation obtained leaves much to be desired.
Til isolering af sådanne rum anvendes ofte opskummede formstoffer, idet en opskummelig flydende formstofblanding sprøjtes ind i rummet, hvorefter formstoffet opskummer og derved frembringer den ønskede isolering.For insulating such compartments, foamed plastics are often used, as a foamable liquid plastics mixture is sprayed into the compartment, whereupon the molding material foams thereby producing the desired insulation.
Det er formålet for den foreliggende opfindelse at tilvejebringe en fremgangsmåde og et apparat, som gør det muligt at opnå en tilfredsstillende udfyldning af et hulrum med relativt små tværsnit med partikelformigt mineraluld, som eventuelt er granuleret på enkel måde uden at anvende formstofskum, men samtidig på en sådan måde, at der opnås en effektiv isolering på grund af en homogen aflejring af det partikelformige materiale og uden behov for komplicerede apparater eller en tidsforbrugende teknologi.It is the object of the present invention to provide a method and apparatus which allows a satisfactory filling of a relatively small cross-sectional cavity of particulate mineral wool, which is optionally granulated in a simple manner without using plastic foam, but at the same time being obtained. such that effective insulation is achieved due to a homogeneous deposition of the particulate material and without the need for complicated apparatus or time consuming technology.
Dette opnås ifølge opfindelsen ved at fremgangsmåden er ejendommelig ved det i den kendetegnende del af krav 1 angivne.This is achieved according to the invention in that the process is characterized by the characterizing part of claim 1.
En sådan fremgangsmåde tillader indblæsning af mineraluld i aflange rum ved hjælp af en luftstrøm, samtidig med at der opnås en meget homogen aflejring af mineralulden, eftersom det gas-formige medium af gasstrømmen kan slippe bort gennem den anden åbning, som hindrer passage af materialet.Such a method allows the injection of mineral wool into elongated compartments by means of an air stream, while obtaining a very homogeneous deposition of the mineral wool, since the gaseous medium of the gas stream can escape through the second opening which prevents passage of the material.
En isolering af denne type ved hjælp af mineraluld har store fordele sammenlignet med en isolering ved hjælp af opskummet plast. Ved den opskummede plast er brandrisikoen meget større end tilfældet er ved mineraluld, samtidig med at opskummet plast har en tendens til at svinde ind efter en vis tid på grund af ældning, således at isoleringsegenskaberne reduceres eller forsvinder fuldstændigt. Svind af opskummet plast påvirker endvidere isoleringen, medens der omvendt i tilfælde af en kompakt masse af skumplast ikke kan opnås en effektiv lydisolering, er det modsatte tilfældet ved hjælp af mineraluld.Insulation of this type using mineral wool has great advantages compared to insulation using foamed plastic. In the case of foamed plastics, the fire risk is much greater than in the case of mineral wool, while foamed plastics tend to fade after a certain time due to aging, so that the insulation properties are reduced or disappear completely. Furthermore, foamed plastic shrinkage affects the insulation, whereas conversely in the case of a compact mass of foam plastic an effective sound insulation cannot be achieved, the opposite is the case with mineral wool.
En fremgangsmåde af denne type er f.eks. velegnet til en hurtig opfyldning af cylindriske kanaler i gulvelementer fremstillet af beton, hvilke kanaler somme tider har en længde på 8 meter og en diameter på 18 cm, hvorved tidsforbruget til opfyldning af sådanne hulrum kun er 5 minutter.A method of this type is e.g. suitable for rapid filling of cylindrical channels in floor elements made of concrete, which channels sometimes have a length of 8 meters and a diameter of 18 cm, whereby the time required for filling such cavities is only 5 minutes.

Fremgangsmåden ifølge opfindelsen egner sig også til fremstilling af isolerede rør til luftkonditioneringsformål, hvor der gøres brug af to tyndvæggede koncentriske stålrør med mellemrummet opfyldt med isolerende materiale. Hidtil er dette mellemrum blevet udfyldt alene med opskummet plast. Ved anvendelse af den foreliggende opfindelse er det imidlertid ikke mere fordret, at rørene skal forsynes med rundt tværsnit, eftersom rør med polygonalt tværsnit, f.eks. rektangulært eller kvadratisk tværsnit, også let kan isoleres.The method according to the invention is also suitable for the production of insulated pipes for air conditioning purposes, using two thin-walled concentric steel pipes with the space filled with insulating material. So far, this gap has been filled with foamed plastic alone. However, using the present invention, it is no longer required that the tubes be provided with a circular cross section, since tubes of polygonal cross section, e.g. rectangular or square cross section, also easily insulated.
Materialeindløbet udmunder direkte i den første åbning, medens den anden åbning fortrinsvis består af en børste eller af perforeringer i en plade af bøjeligt materiale. Denne konstruktion gør det muligt for det gasformige medium til indblæsning af mineralulden at slippe bort gennem perforationerne, således at mineralulden kan aflejres effektivt og ensartet i rummet, som skal fyldes.The material inlet opens directly into the first opening, while the second opening preferably consists of a brush or perforations in a sheet of flexible material. This construction allows the gaseous medium for supplying the mineral wool to escape through the perforations, so that the mineral wool can be deposited effectively and uniformly in the space to be filled.
Opfindelsen omfatter tillige et apparat til udfyldning af et rum, der er aflukket ved den ene ende, fortrinsvis et aflangt rum, med isolerende partikelformigt materiale, fortrinsvis mineraluld, der eventuelt er granuleret, omfattende en ledning til tilførsel af materiale forsynet med et indløb for gasformigt medium, under udøvelse af fremgangsmåden ifølge krav 1, hvor ledningen til tilførsel af materiale på ydersiden har et tætningslegeme forsynet med en eller flere åbninger til passage af gas, men forhindring af materialepassage og er ejendommeligt ved, at tætningslegemet består af bøjeligt materiale.The invention also comprises an apparatus for filling a space enclosed at one end, preferably an elongated space, with insulating particulate material, preferably granular wool, optionally granulated, comprising a conduit for supplying material provided with an inlet for gaseous material. medium, in accordance with the method of claim 1, wherein the conduit for supplying material on the outside has a sealing body provided with one or more openings for passing gas, but obstruction of material passage and is peculiar in that the sealing body consists of flexible material.
Et apparat af denne type er i stand til at udfylde aflange rum hurtigt med et isolerende partikelformigt materiale, såsom mineraluld, der eventuelt er granuleret, eftersom en blanding af gas og materiale kan udfylde det aflange rum ved hjælp af en normal transportindretning for materialet. Efter udfyldningsoperationen er afsluttet, kan det gasformige medium flyde bort gennem de ovenfor beskrevne åbninger, som imidlertid forhindrer passage af materiale. Ved efterhånden at bevæge transportiedningen med tætningslegemet i retning mod enden af det aflange rum, opnås der en ensartet udfyldning af rummet, som resulterer i en særdeles god isolering.An apparatus of this type is capable of filling elongate compartments rapidly with an insulating particulate material, such as mineral wool, which may be granulated, since a mixture of gas and material can fill the elongated compartment by means of a normal conveying device for the material. After the filling operation is completed, the gaseous medium can flow through the apertures described above, which, however, prevent the passage of material. By gradually moving the conveyor belt with the sealing body towards the end of the elongated compartment, a uniform filling of the compartment is obtained, which results in a very good insulation.
Et foretrukket tætningslegeme består af en børste, gennem hvilken det gasformige medium bortledes uden at medføre noget mineraluld.A preferred sealing body consists of a brush through which the gaseous medium is discharged without causing any mineral wool.

Fremgangsmåden og apparatet ifølge opfindelsen kan forøge mulighederne for anvendelse af mineraluld, både granuleret og ikke-granuleret, i betydelig grad. I tilfælde af problemer med hensyn til isoleringen af aflange hulrum, som skal udfyldes med et isolerende materiale, behøver man ikke længere at anvende de meget kostbare former for plastskum, der har en række medfødte ulemper, men man kan i stedet anvende de betydeligt billigere materialer i form af mineraluld.The process and apparatus according to the invention can greatly increase the possibilities of using mineral wool, both granulated and non-granulated. In the case of problems with the insulation of elongated cavities to be filled with an insulating material, the very expensive forms of plastic foam having a number of innate disadvantages are no longer needed, but the considerably cheaper materials can be used instead. in the form of mineral wool.
Opfindelsen skal i det følgende beskrives nærmere med henvisning til en udførelsesform vist på den medfølgende tegning, på hvilken fig. 1 viser et længdesnit gennem et apparat ifølge opfindelsen samt en aflang kanal i et betondækelement, som skal udfyldes med mineraluld; fig. 2 viser et lignende dækelement set fra enden; fig. 3 viser et apparat ifølge opfindelsen anvendt til udfyldning af mellemrummet mellem to koncentrisk anbragte rør, således som anvendt til luftkonditioneringsinstallationer; og fig. 4 viser et tværsnit ved IV på fig. 3.The invention will now be described in more detail with reference to an embodiment shown in the accompanying drawing, in which: FIG. 1 is a longitudinal section through an apparatus according to the invention and an elongated channel in a concrete cover element which is to be filled with mineral wool; FIG. 2 shows a similar cover element seen from the end; FIG. 3 shows an apparatus according to the invention used for filling the gap between two concentrically arranged pipes, as used for air conditioning installations; and FIG. 4 shows a cross section at IV in FIG. Third
Fig. 2 viser et betondækelement 1 med aflange kanaler 2 med en længde på 8 meter og en diameter på 18 cm. Hver aflang kanal 2 er begrænset af en væg 3.FIG. 2 shows a concrete deck element 1 with elongated ducts 2 with a length of 8 meters and a diameter of 18 cm. Each oblong channel 2 is restricted by a wall 3.
De aflange kanaler 2 er ved den ene ende lukket af en væg 4.The elongate ducts 2 are closed at one end by a wall 4.
Til udfyldning af disse aflange rum 2 med mineraluld 5 anvendes et apparat, som omfatter en tilførselsledning 6, som eventuelt kan være bøjelig, til tilførsel af materialet. Denne ledning 6 er forbundet med en kilde 8 til gasformigt medium (en blæser) til tilførsel af gasformigt medium til ledningen 6. Et indløb 7 for mineraluld, som eventuelt kan være granuleret, udmunder i ledningen 6.To fill these elongated compartments 2 with mineral wool 5, an apparatus comprising a supply line 6, which may be flexible, is used to supply the material. This conduit 6 is connected to a source 8 for gaseous medium (a fan) for supplying gaseous medium to conduit 6. An inlet 7 for mineral wool, which may be granulated, opens into conduit 6.
På ledningen 6 er der et manometer 13, ved hjælp af hvilket trykket af det gasformige medium i ledningen let kan bestemmes.On the conduit 6 there is a pressure gauge 13 by which the pressure of the gaseous medium in the conduit can be easily determined.
Via en åbning 9 blæses det gasformige medium med partikelf ormigt isoleringsmateriale ind i rummet, som skal udfyldes.Via an opening 9, the gaseous medium with particulate insulating material is blown into the space to be filled.
Indløbet 12 af ledningen 6 er omgivet af en ydre flange 10 af stift gummi, hvilken flange i det væsentlige lukker tværsnittet af det aflange rum.The inlet 12 of the conduit 6 is surrounded by a rigid rubber outer flange 10, which substantially closes the cross-section of the elongated compartment.
Flangen 10 er som vist på fig. 4 forsynet med perforeringer 11, gennem hvilke gassen kan slippe bort, men udformningen forhindrer en passage af det partikelformige isoleringsmateriale.The flange 10 is as shown in FIG. 4 provided with perforations 11 through which the gas can escape, but the design prevents a passage of the particulate insulating material.
5 144646 På grund af perforeringerne 11 kan det partikelformige isoleringsmateriale ledes til rummet 2 med høje hastigheder, hvorved der ikke opstår vanskeligheder på grund af inhomogen aflejring af varmeisolerende eller lydisolerende materiale.Due to the perforations 11, the particulate insulating material can be led to the space 2 at high speeds, thereby avoiding difficulties due to inhomogeneous deposition of heat insulating or sound insulating material.
Fig. 3 viser et andet apparat, som tjener til udfyldning af et ringformet rum mellem to stålrør 3a og 3b placeret koncentrisk i forhold til hinanden, hvilke rør anvendes til transport af ventilationsluft. Det vil imidlertid være klart, at anvendelsen af sådanne rør ikke er begrænset til dette formål.FIG. 3 shows another apparatus which serves to fill an annular space between two steel pipes 3a and 3b located concentrically relative to each other, which pipes are used for transporting ventilation air. However, it will be clear that the use of such pipes is not limited to this purpose.
Rørene 3a og 3b er placeret koncentrisk i forhold til hinanden og er lukket ved den ene ende ved hjælp af et dasksel 14.The tubes 3a and 3b are located concentrically relative to each other and are closed at one end by a cover 14.
Til udfyldning af rummet mellem rørene 3a og 3b, som er placeret koncentrisk i forhold til hinanden med et isoleringsmateriale bestående af mineraluld 5, anvendes en central tilførselsledning 6, som udmunder i en ringformig ledning afgrænset af væggene 6a og 6b til tilførsel af materialet. Ledningen 7 til tilførsel af isoleringsmaterialet udmunder i ledningen 6, medens man ved hjælp af en blæser 8 indfører luft i ledningen 6.To fill the space between the pipes 3a and 3b, which are concentrically positioned relative to each other with an insulating material consisting of mineral wool 5, a central supply line 6, which opens into an annular line bounded by the walls 6a and 6b, is used for supplying the material. The conduit 7 for supplying the insulating material opens into the conduit 6 while introducing air into the conduit 6 by means of a blower 8.
For at opnå en hurtig udfyldning af rummet 2 mellem rørene 3a og 3b er der en flange 10 på ydersiden af væggene 6a og/ eller 6b, hvilken flange er forsynet med perforeringer 11 til bortledning af gassen, men gennem hvilke det isolerende materiale ikke er i stand til at passere. Flangen 10 består af stift gummimateriale, som letter indførelsen i rummet 2.In order to achieve a rapid filling of the space 2 between the pipes 3a and 3b, there is a flange 10 on the outside of the walls 6a and / or 6b, which flange is provided with perforations 11 for discharging the gas, but through which the insulating material is not contained. able to pass. The flange 10 consists of rigid rubber material which facilitates insertion into the space 2.
Det er blevet konstateret, at flangen kan erstattes af en børste, eftersom denne let kan indføres og fjernes fra rummet 2, og eftersom at børstehårene ikke forhindrer gassen i at strømme ud, hvorimod de forhindrer, at mineraluldpartiklerne slipper forbi.It has been found that the flange can be replaced by a brush since it can be easily inserted and removed from the space 2 and since the bristles do not prevent the gas from flowing out, while preventing the mineral wool particles from passing.
Det er indlysende, at diameteren af den indre væg 6b af tilførselsledningen 6 for materialet kan vælges således, at den grænser op til ydersiden af røret 3b og det ydre rør 3a uden stort spillerum.It is obvious that the diameter of the inner wall 6b of the supply line 6 of the material can be selected so that it adjoins the outside of the tube 3b and the outer tube 3a without much clearance.
Det vil være klart, at den foreliggende opfindelse ikke er begrænset til anvendelsen af mineraluld, men også kan anvendes ved andre uorganiske isoleringsmaterialer, såsom perlit-korn.It will be understood that the present invention is not limited to the use of mineral wool, but can also be used with other inorganic insulating materials such as perlite grains.
Med henblik på simplificering af apparatet anvendes der en type tilførselsledning for materialet. I dette tilfælde forsynes ledningen 6 med tilpassede tætningsorganer til tætning af et tværsnit af rummet, som skal isoleres.For the purpose of simplifying the apparatus, a type of supply line is used for the material. In this case, the conduit 6 is provided with adapted sealing means for sealing a cross-section of the space to be insulated.
