Background Art

Is it already known? a device of the aforesaid type, in which: 7 a flush-mounted fan is mounted in the sound-insulated housing, as well as a suction blower extracting the humid air / file DE-OS 3® 15 ΐ bΐ /. The air enriched, for example, by the moisture removed from the insulating material, is pushed from the intake vent to the dryer, which; however, since the two fans causing the noise in this known device are arranged in a sound-insulated housing, it is possible to keep the device 2 during operation, for example, in the apartment. Due to the use of fans, this known device is only suitable for the dehumidification of relatively small drying objects. It is true that it is facilitated by the transport of the fans in the same housing, but due to the connection of the air dryer to the suction fan and the use of the hoses connecting the connection sleeves of the fan to the plaster, the alignment of this known device is nevertheless difficult.

There is also known a moisture removal device in which a suction fan and a pre-arranged water separator (EP 0 24/2: 6) are housed in the same mobile housing. While the inlet fan is interconnected during insertion of the water separator with the dried insulating layer, the fan outlet is led out of the housing and may optionally be connected to an air dryer. Also, this known device is only suitable for smaller dried objects; is it also known during its operation? left in confined space. In doing so, it may be disadvantageous that the heated, moisture-enriched heated air extracted from the insulating material is again fed into the space where the furniture found there can suffer; due to increased humidity and temperature injury.

It is also known to dehydrate the material under the cover layer in which it is debris; the air layer, the cover layer is pressed into the dried material and the second edge of the cover layer is then enriched with moisture. 044 /. With this known device, it is possible; practically create a closed stream of air, because both the pressure and suction fans and the condensers are placed behind the sweep in the air stream. Thus, in this known device, ambient air is not subject to moisture, but the purpose of establishing this known device must be to interconnect the aggregates, which is not an insignificant need for transport and labor. Yet it remains! here, too, in a dried-out space, which substantially reduces the space required? usability of this space.

Even if the individual units are housed in a foam box, all known devices require quite a number of machines, as air dryers must be connected to them at least. In addition, these devices are mostly designed to dry relatively small objects; they are therefore kept regularly in the dried areas, which significantly affects their further usability, also due to development, noise and heat. Since the non-substantial increase in humidity and heat in the space is usually associated with the drying of the renovated building, there is a risk of damage to the furniture and equipment in the restored building.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a device of the kind described by which both large-scale and small objects can optionally be de-humidified, and wherein only a small amount of work is involved in transporting and establishing the device. In this connection, it is also possible to provide the apparatus of the invention outside the dried areas or buildings, so that it can continue to be used without significant noise and space requirements. - 3 -

The object of the invention is to provide a device for removing moisture from layers or hollow spaces lying under the cover of the invention, the principle being that at least two pressure conveyors arranged in parallel in their air stream are connected to a corresponding quantity of air driers in parallel, and that there are also a plurality of in parallel suction conveyors arranged in parallel, wherein the pressure conveyors, the suction conveyors and the air dryers are separated from one another on or in the common bogie, where they are arranged and at least the connection between the air dryer and the pressure conveyors is hermetically separated from the surroundings.

With the use of multiple pressure and suction conveyors, sufficient performance and redevelopment of large-area objects is achieved in the inventive device. By connecting or disconnecting individual compressors, the volume of circulating air can be adapted to the size of the dried object, so that even small objects can be dehumidified. Here, the pressure conveyors, suction conveyors and dryers are arranged on a common transport chassis or frame and must only be connected to the insulation by means of pressure and suction pipes. a layer or similar dry-airspace. Since the pressure conveyors, the suction conveyors and the air dryers are arranged on a common transportable chassis, the weight to be moved and required for transporting or translating the inventive device, consisting of different, agrees. -,. VA. Due to the parallel arrangement of the pressure conveyors and the suction conveyors, the air pressure achieved by the device according to the invention is roughly the same in comparison with the series shifting of these elements, without substantially increasing the pressure. risk of fire or machine wear.

Since it is also possible to achieve a higher pressure with the device according to the invention, relatively long air hoses can be used for supplying air to and from the device for conveying dry air and humidity. Therefore, the yy-finding facility is intended to be located outside the restored building, and only air hoses are introduced into its interior. This has the advantage that the spaces can be practically used without hindrance due to their non-noise or heat interference. In this case, it is advantageous if a generator is provided on the common bogie or in the common housing for producing the electric current for supplying the compressors or, optionally, the air drier. Thus, it is possible to select the location of the device according to the invention, irrespective of the need for an external source of the external alarm.

It is also advantageous if the pressure conveyors, the suction conveyors, the air dryers and possibly the current generator are arranged in a common, preferably sound-insulated, transportable housing and housed therein in separate chambers. By separating the pressure conveyors, the suction conveyors and the air dryers from each other, it is possible to optimally distribute the load alloys inside the cabinet while achieving high performance. In this simple manner, due to the separation of the aggregates, the connection can be hermetically separated. between air dryers and press brakes.

In order to achieve good accessibility and low maintenance, it is expedient for the individual chambers in the housing to have access openings on the outside.

One particularly simple embodiment of the invention assumes that? each outlet of the air dryer to the hermetically sealed chamber of the pressure conveyors, which draw the necessary air from the chamber.

In order to allow the air needed to dry up in the atmosphere and to enrich it with moisture, it is expedient if the chamber is! air dryers and a chamber of suction conveyors are provided with at least one air opening leading out.

The installation and operation of the inventive device is facilitated when the air outlets of the pressure conveyors and the air intake conveyors are connectable and dried by the insulating layer or hollow space by means of coiled air hoses, if the winding drums of these hoses are also housed in the housing or on top.

In order to adapt the air output of the pressure conveyors and the suction conveyors to each other and to prevent overpressure in the floor noise damping or the like, it is useful if the individual compressors of the device have approximately the same air transport capacity per time unit. In this case, it is advantageous if the control of at least those compressors which switch on or actuate the same number of suction or pressure conveyors in the desired number of operating pressure or suction conveyors is arranged.

One particular preferred embodiment of the invention envisages that such a significant arrangement will be used as a mobile vehicle, for example a trailer, so that it is possible to make it very easy and quick to repair a renovated building, for example, to be used for the rehabilitation of large areas; a large enough number of machines or corresponding strong machines. , Figures: in the drawings

The invention will be described, with all its essential and relevant features, in one exemplary embodiment, in the form of drawings which, in a schematic view, show, in a sectional view, a device for removing moisture from insulating layers or hollow spaces under the cover, compressors, air dryers and a current generator are arranged in a common transport box, Fig. 2 'represents the apparatus of Figs. 1 with respective aggregates in a perspective side view, and Fig. 3 illustrates the apparatus of Figs. redeveloped building. An exemplary embodiment of the invention

Ha fig.1! the device 1r is shown in cross section. The device 1 serves to dehumidify the insulating layers or hollow spaces underneath the covering layer, as is the case, for example, in underlays, walls, ceilings or the like. The device t is equipped with six compressors, of which? three are provided as pressure conveyors 2; for introducing dry air into the insulating layer or cavity and three other suction conveyors 2 for extracting moist air from the insulating layer. In the direction of the air conveyors 2, three air driers are arranged in the direction of the air conveyors, with the aid of which the air-dried material is removed from the atmosphere before being introduced into the insulating layer or hollow space.

The pressure conveyors 2, the suction conveyors 2 and the air dryers 5 are always arranged in parallel in the air flow. The pressure conveyors 2, the suction conveyors 2 and the air dryers 8 are mutually mounted in a common transportable housing 26 - 6 in which a current generator 6 is also arranged for the current supply of the compressors, i.e. the pressure conveyors 2 and the suction conveyors 3. They are disposed in separate housing chambers K1, K2, K3 and K4. Due to the separation of these compartments K1, K2, K3, K4, it is possible in a simple way to separate the connections between the air dryers 4 and the pressure conveyors 2 from the environment: while the air dryer chamber K3 and the chamber K4 of the suction conveyors 3 are provided with a leading air opening 7 whereby the air required for drying can be extracted from the atmospheres, the air dryers 4 with their outlet ports 8 are hermetically sealed with the chamber K2 in which the pressure conveyors 2 are located. air from the atmosphere, which is opened by air opening 7 of the chamber K3 into the housing 5. Hereby the outlets 9 of the pressure conveyors 2 are connected to each other by a common air pressure conduit 10 passing through the joint 5 and leading to a compressed air connection. 11 BC stupnému vkomoře K5. From there, the dry air drawn in by the pressure conveyors 2 and the air hoses 12 is pressed into the dehumidified insulating material.

Since the air inlets of the pressure conveyors 2 are not immediately connected to the outlet ports of the 8 air dryers J, they draw in the necessary amount of air through; its hermetically sealed chamber K2, it is possible to operate any number of pressure conveyor 2 machines with individual air-dryers.

With the aid of the pressure conveyors 2, the dry air is forced into the insulating layer, which is generally situated under the plaster or similar covering layer, by expansion joints usually arranged at the edge of the covering layer, or by openings particularly covering the layer made. In order to avoid exposing the salted space and the furniture contained therein to undesirable elevated temperature or humidity in this space, the air is subsequently forced through the insulating material and thus enriched with moisture, again in another location drawn or prepared by expansion joints or openings. - 7 -

The suction of the humidified air stream takes place by means of the suction conveyors 3, which are arranged in the chamber K4 of the χ. For this purpose, the suction conveyors 3 and the corresponding expansion joints or openings of the refurbished space are connected with the air hoses 12, whereby the air hoses 12 can be connected to the suction air connection ports 1J accessible from the chamber K5 &quot;

Also, the suction conveyors J in the chamber K4 are arranged in parallel; while their suction inlets 14 are tightly coupled to the intake air connection heads 13, their outlets 15 only lead into the interior of the chamber K4, where the airflow 7 is arranged to allow the atmosphere to escape.

1 to 3, the individual chambers B to 14 as well as the chamber K5, which comprise both the flow generator 5, the pressure conveyors 2, the suction conveyors 3a of the air dryer 4, and the connection nozzles 11 and 13, respectively each of which is provided with an access opening 16 which is always closable by the door and allows entry into the coils K1 to K5. 2 it can be seen that the air outlets of the pressure conveyors 2 and the air inlets of the suction conveyors 3 can be connected to the dehumidified insulating layer or hollow space by the winding hoses 12, the winding drums 17 being FIG. 2 shows that the device housing 5 is designed as a two-sided trailer capable of being transported by road, which can be connected to a transport vehicle (not shown) by means of a hitch 18.

In order to avoid overpressure in the dehumidified insulating layer and to convey the conveying volume of the conveyors 2 in operation to the conveying volume of the suction conveyors, the individual compressors, i.e. the pressure conveyors 2 and the suction conveyors 3, always have the same air transport volume per time unit. If only two or even one pressure conveyor 2 is brought into the vehicle and the suction conveyor can be adapted to the capacity of the dehumidified object. In this case, the control 19 is shown in FIG. 2, which, when the number of suction conveyors 2 in operation is switched on, switches on the same number of suction conveyors 3. - a - In the apparatus T shown here, the condensation dryer should be designed as an air dryer. built for a total dehumidification capacity of 1000 liters per d®n at relative humidity. 8 ° C and 25 ° C. The air drawn in from the atmosphere by the pressure conveyors 2 is dried by condensation dryers to 40% relative humidity to keep it dry; was it? as a dry air, it can be pressed into the dehumidified insulating material. In the K2 ~ chamber are * as. the pressure conveyors 2 serving the pressurized device 6 are provided by the total transport air power 23? m / min and are arranged in parallel, so that they can all be put into operation at once, or just pressurized conveyor 2 or two pressure conveyors 2. The device T shown here has thus an air volume sufficient for technical drying in the iz® area up to approx. 70 m of foundation tarpaulin. As a result of the parallel shifting of the compressors, the device can be formed as a mobile drier from a desiccated object up to 300 m, and this distance is easily overcome by the air hoses 12; the lacquer is shown in FIG. It is possible to locate the necessary machines and aggregates of the device outside the building in a common location, so that often the difficult location of the aggregates inside the building in the proper place is avoided, so that the noise-damping or even soundproofed housing can be so dampened that it does not disturb the occupants or users of the building. the simplest installation required for the operation of the device, since only the housing 5 and the corresponding T2 air hoses need to be placed in the area of the refurbished building Since the housing 5 of the device 2 is designed as a mobile trailer and provided with a T8 hitch, the device J can be very quick and easy shipped? where the positioning device is provided, if the device JT is provided with a corresponding number of machines or corresponding corresponding machines for the removal of very large surfaces, the load net can be optimally distributed by separating the aggregate nodes in the housing 5 by dividing walls 20 dividing the housing 5 of the chamber ΓΓ to K5. and a high air passage, so that both the line and the branch can possibly be supplied and each air line can be supplied with sufficient air and sufficiently high air pressure. - 9 -
