Abstract
The present invention relates to a method and an apparatus for filling a volume of insulating material in the form of particles.
[FR2393224A1]
Description
This invention relates to a method of and an apparatus for filling an elongate space with insulating material, more particularly mineral wool which may be granulated.
The use of mineral wool, whether or not granulated, for heat 5 and/or sound insulating purposes, is known. To that end the mineral wool may, for instance, be shaped into objects, such as half-tubeshaped parts for insulating pipe lines.
It is also known to cover an object and to fill up the remaining space with mineral wool, whether or not granulated, by blowing a stream of gas into this space.
Filling elongate spaces of relative small cross-section is, however, very difficult since, as a result of the recurring currents of air, the particles of mineral wool form a very poor homogeneous deposit so that the insulation obtained leaves much to be desired.
- 2 4 6 3 2 9
For insulating such spaces, foamed plastics are frequently used, whereby an expandable liquid plastics composition is sprayed into the space, whereafter this plastics composition is foamed, which provides the desired insulation.
The present invention provides a method and apparatus which permit satisfactory filling of spaces having relatively small crosssections with insulating material, particularly mineral wool, whether or not granulated, in a simple manner without making use of foamed plastics, while forming a very efficient insulation by a homogeneous deposit of the insulating material , >and while avoiding the need for very complex apparatus or time consuming technology.
According to one aspect of the invention, there is provided a method of, filling an elongate space having only one open end with loose particulate insulating material and maintaining the said insulating material in a loose state, in which the insulating material is blown into the space by means of a gaseous medium, wherein the cross-section of the space is sealed by means of a sealing body, a first aperture in the said sealing body connected with an inlet for insulating material being left open for blowing particulate insulating material into the said space by means of a stream of gaseous medium, and as least one second aperture in the said sealing body also being left open for preventing the passage of the said loose insulating material but allowing the discharge of said gaseous medium from the space downstream of the said sealing body.
Such a method suitably allows blowing of mineral wool into an elongate space with the aid of a current of air, whereby a very homogeneous deposit of the mineral wool occurs, since the gaseous
- 3 A632S medium may escape through the second aperture or apertures which prevent the passage of the mineral wool.
An insulation of this type by means of mineral wool presents great advantages as compared with an insulation by means of foamed plastics. In the case of foamed plastics the risk of fire is much greater than in the case of mineral wool, while foamed plastics will also crumble after a certain period of time because of ageing, so that the insulating properties are reduced or disappear altogether. Shrinking of foamed plastics further impairs insulations, and in the case of a compact mass of foamed plastics, an effective sound insulation cannot possibly be achieved, contrary to an insulation by means of mineral wool.
A method of this type lends itself well for example for a quick filling of cylindrical ducts in concrete floor elements, which ducts sometimes have a length of 8 meters and a diameter of 18cm, whereby the time required for filling such spaces is 5 minutes only.
Another important practical use is the formation of insulated tubes for air-conditioning purposes whereby use is made of two thinwalled concentric steel tubes, the space between which has to be filled with an insulating material; this space filling has up to the present been exclusively carried out with foamed plastics. When use is made of the present invention, however, tubes of annular cross-section are no longer compulsory, since now also tubes having polygonal cross-sections, e.g. rectangular or square cross-sections, can be easily insulated as well.
The insulating material inlet suitably opens into the first aperture, whilst the second apertures preferably consist of perforations in a plate constituting the sealing bocfy, which plate may be flexible.
- 4 4 6 3 2 9
The latter construction enables the gaseous medium for blowing the mineral wool to escape through the perforations, so that the mineral wool can be deposited efficiently and homogeneously in the space to be filled.
The invention in another aspect provides apparatus when used for filling an elongate space open at one end with loosely held particulate insulating material, comprising a line for conveying loose particulate insulating material provided with an inlet for a gaseous medium, wherein the line for conveying insulating material has on its outside a sealing body for sealing the cross-section of an elongate space having only one open end, the said sealing body being provided with one or more apertures allowing discharge of gaseous medium but preventing the passage of loose insulating material from the space downstream of the said sealing body.
An apparatus of this type allows elongate spaces to be filled rapidly with an insulating material, such as mineral wool, whether or not granulated, since a mixture of gas and mineral wool may fill an elongate space via a normal conveyor for the mineral.
After the filling operation is completed the gaseous medium can flow away through the above described apertures which prevent, however, passage of insulating material.
By gradually moving the conveying line with the sealing body to the end of the elongate space, uniform filling of this space is effected, the result of which is a particularly good insulation.
The sealing body may consist of a sealing partition, which comprises a plate, preferably a perforated plate, by means of which a very regular discharge of gaseous medium is ensured.
- 5 4S32S
Another preferred sealing bociy consists of a brush body through which the gaseous medium may be quickly discharged without carrying along any mineral wool.
The method and apparatus in accordance with the invention can increase the possibilities of operating with mineral wool, whether or not granulated, to a considerable extent. In case of problems with respect to the insulation of elongate spaces which have to be filled with an insulating material, the very expensive plastics foams with all their inherent disadvantages need be used no longer; instead thereof considerably cheaper materials in the form of mineral wool can be used.
The invention will be further described, by way of example only, with reference to the accompanying drawings, wherein:
Figure 1 is a longitudinal section of an apparatus according to the invention shown filling an oblong duct in a concrete floor element with mineral wool;
Figure 2 is a side elevation of a similar floor element;
Figure 3 is a longitudinal section of another apparatus according to the invention shown filling a space between two concentrically arranged tubes such as used for airconditioning installations; and
Figure 4 is an enlarged view of the part of Figure 3 indicated by reference numeral IV.
Figure 2 illustrates a concrete floor element 1 with oblong ducts 2 each having a length of 8 meters and a diameter of 18cm.
Each oblong duct 2 is bounded by a wa!13. The oblong ducts 2 are closed at one end by a partition 4.
To fill each oblong space 2 with mineral wool 5, an apparatus is applied which comprises a conveying line 6, which may or may not be flexible, for conveying the insulating material. This line 6 is connected with a source 8 of gaseous medium (a blower) for feeding - 6 4 632 a gaseous medium to the line 6. An inlet 7 for mineral wool, whether or not granulated, leads into the line 6.
On the line 6 is a manometer 13 by means of which the pressure of the gaseous medium in the line 6 can be easily determined.
The gaseous medium together with the insulating material is blown via an aperture 9 into the space to be filled.
The inlet 12 of the line 6 is encircled by an outer flange 10 of rigid rubber, which flange substantially closes the crosssection of the oblong space. The flange 10, as best illustrated in Figure 4, is provided with perforations 11 through which gas may escape but the construction of which prevents passage of the insulating material.
Due to the perforations!1, the insulating material can be guided to the space 2 at high velocities, whereby no difficulties occur owing to a non-homogeneous deposit of heat-insulating or soundinsulating material.
Figure 3 illustrates another apparatus which serves to fill an annular space inbetween two steel tubes 3a and 3b arranged concentrically with respect to each other are closed at their end by a closure 14.
To fill the space 2 inbetween the tubes 3a and 3b, positioned concentrically with respect to each other, with an insulating mineral wool material 5, use is made of a central supply line 6 which leads into an annular space bounded by the walls 6a and 6b of the conveying line. A line 7 for conveying the insulating material leads into the line 6, while air is blown into the line 6 by means of a blower 8.
For a quick filling of the space 2 inbetween the tubes 3a and
- 7
3b, there is a flange 10 on the outside of the walls 6a and/or 6b which is provided with perforations 11 for permitting gas to pass through which no insulating material is able to pass. This flange 10 consists of a rigid rubber material so as to facilitate introduction into the space 2.
It has been found that the flange can be appropriately replaced by a brush because the latter may be easily introduced into and removed from the space 2, since the hairs of the brush do not impede the gas from flowing away, whereas they prevent the parti10 cles of mineral wool from being carried along.
As a matter of course, the diameter of the inner wall 6b of the conveying line 6 for the material can be so chosen that it lies adjacent the outside of the tube 3b, without much clearance.
It will be clear that the present invention is not limited 15 to the use of mineral wool, but may also be applied with other mineral insulating materials such as perlite grains.
In order to simplify the apparatus, one type of supply line 6 for insulating material is generally used. In that case the line 6 is provided with adapted sealing portions for sealing the cross-section of the space to be insulated.
