Definitions

• the present invention relates to a device for aspirating and storing, before and during their cooling, combustion residues of wood, charcoal (or their derivatives). These residues come from combustions carried out in various heating and / or cooking appliances.
• the present invention aims more particularly to minimize the risk of burns or dust generation during these suction and storage operations.
• the co l e c te d e c e s re s i of s traditionally using shovels, brooms and buckets, generates dust and poses the risk of burns when accessing the recesses in which they are housed. In addition, there is often the problem of preserving these residues until they have completely cooled.
• the device according to the invention overcomes these various drawbacks.
• the present invention relates to a device for suction and storage of residues of the type comprising a double-walled storage tank, adapted to contain said residues, said tank being provided with a suction pipe suitable for introducing the residues in the tank and of an evacuation pipe outside the tank, of the air sucked up with these residues, said device being characterized in that it comprises, upstream of the evacuation pipe, a filtration cartridge provided a plurality of filters; a first filter unit being provided with an unclogging means suitable for scraping the entire wall of the first filter unit and for driving down the residues thus detached.
• the present invention also relates to a corresponding filter cartridge.
• the device according to the invention is made of heat resistant materials, arranged so as to reduce the radiation
• FIG. 1 is a vertical sectional view of a suction and storage device according to the present invention
• FIG. 2 is a sectional view along line II II of Figure 1.
• FIG. 3 is a perspective view, partially cut away, showing the rotary brush according to the invention and its action on the first filter unit 24.
• the device 10 according to the invention is a vertical canister type vacuum cleaner, composed in particular of a safety storage tank 11 and a cover 12 surmounted by the electrical equipment 13 necessary for its operation.
• the storage tank 11 has a double wall 11a, 11b, including the bottom 15.
• the internal wall 11a can constitute a removable container and is covered on the outside with insulating material 16.
• An air space 17 separates it from the external envelope 11b, which is perforated at least over part of its periphery by ventilation openings 18, so that an air circulation (arrows F) is established, naturally, between the internal walls 11a and 11b and allows the ashes 14 contained in the tank 11 to be cooled.
• the ashes 14 or hot residues are sucked up by a suction pipe 19, to be sent to the storage tank 11.
• a suction pipe 19 to be sent to the storage tank 11.
• a part of the ambient air is entrained with the ashes. This air, once in the tank
• a removable, removable, cleanable and heat-resistant fire filter cartridge 20 has been installed upstream of the suction turbine T.
• This cartridge has inside a casing 21 three cylindrical filter units 22, 23, 24 arranged concentrically and each removable:
• the outer cylinder 22 or third filter unit is lined with mineral wool, asbestos substitutes or the like, and is porous in order to retain the micronized particles escaped from the first two filter units 23, 24,
• the middle cylinder 23 or second filter unit is lined with stainless steel wool and stops the coarsest dust not retained by the first filter unit 24,
• the internal cylinder 24 or first filter unit acts as a primary filter and consists of a rigid hollow cylinder (FIG. 3), perforated with a multitude of microscopic holes 25. It is this unit which stops almost all of the fly ash entrained with suction air. It should be noted that the aspiration of air by the pipe 19 obliges the latter to pass into the tank 11, then successively through the first, second and third filter unit 24, 23, 22, before being brought in. towards a duct 40 for supplying air to a suction turbine T.
• the first filter unit is advantageously provided with an unclogging means produced by a rotary brush 26 tri-blades.
• This brush 26 is rotated about an axis A located in the center of the first filter unit 24.
• the axis A passes through the cover 12 and is driven by any suitable means, for example by a motor forming part of the electrical equipment 13-
• Each of the blades 27 ( Figures 2 and 3) of the brush is inclined at an angle "- • . ( Figure 3) relative to the vertical, in order to bring down any particle of ash detached from the wall of the first filter unit 24 by the rotation of the brush.
• the free end of each of the blades rubs (scrapes) in effect against the wall of the first filter unit 24 and prevents clogging of the perforations 25 thereof (or at least considerably delays it).
• the inclination of the blades 27 downwards promotes the creation of a slight eddy at the level of the first filter unit 24 and further improves the descent by gravity of the fly ash towards the bottom of the tank.
• the axis A drive means can be operated with a simple handle (therefore manually) or electrically with a small motor fitted with a speed reducer. It should be noted that the blades 27 are distributed approximately around the axis A.
• the inner face of the cover 12 is lined with a thermal insulating material but also a sound insulator.
• the electrical equipment 13 suction turbine and / or brush drive motor
• suction turbine and / or brush drive motor is fixed on the cover 12, on an insulating soleplate (not shown), in a raised manner to form an insulating air gap between the cover and these electrical appliances.
• the suction turbine T (shown diagrammatically) could nevertheless be damaged when aspirating very hot ashes or residues.
• an ambient air intake B is provided between the suction circuit and the inlet of this turbine, in order to lower the temperature of the air flow.
• a conventional system (not shown) of paper and fabric bags - or better, in mineral or other fire resistant materials - is provided.
• the device according to the invention is particularly intended for cleaning open or closed hearth fireplaces, stoves, stoves, burning wood, coal or their derivatives. It can of course be used like a conventional vacuum cleaner and suck up water.
• the filter cartridge 20 is contained in a casing 21 put in place by snap-fastening in the cover 12 of the tank. Thus, it is possible to easily and completely change the filter cartridge and replace it with a new cartridge.
• the casing 21 of this filter cartridge can be removed (by simple snap-fastening 50) to allow access to the three filter units 24, 23, 22 and their removal for cleaning by any suitable means.
• the present invention is not limited to the embodiment described and encompasses any variant within the reach of ordinary skill in the art.
• the device can also be used for clearing non-hot powdery rubble, such as sawdust, plaster, etc.
