Description

The Innovation relates to a device according to protection claim 1.

Hot water storage for use in heating installations and / or facilities for provision of warm water are known in different versions. such Memory exist basically from a kettle to collect water from a kettle its outer surface enclosing thermal Insulation preferably made of foamed plastic, for example made of plastic foam (eg PU-foam).

task The novelty is to show a device with that in particular rational way the production of the respective thermal insulation by foaming of the relevant boiler possible is. To the solution This object is a device according to the protection claim. 1 educated.

at the device according to the invention becomes the to be foamed Boiler always upright, d. H. with his boiler axis in oriented vertically in the shape of the mold, so then after the tight closure of the mold or the shape forming moldings between the outer surface of the boiler and the inner surface of the Form of for the foaming Form space used with the plastic material is formed.

A Particularity of the device according to the innovation is that a lower molding of the mold, which (molding) also prefers the stand area for the Kessel forms, in the horizontal direction or substantially in horizontal direction in the form and moved out of the form laterally can be, so then on this example palette-like or formed as a pallet molding the respective boiler before put the introduction into the mold and can be prepared for the foaming. In a preferred embodiment The innovation is at least two such lower moldings in provided horizontally movable, in such a way that in each case a molded part within the mold and a molded part outside the form is located, and alternately at two opposite Sides of the form. This gives you the opportunity during the Umschäumens or overmolding a boiler within the closed mold on the side of the mold located lower molding already shut off another boiler and prepare for foaming, so immediately after the expiration of the the foaming and curing of the plastic necessary cycle time of the foamy boiler from the open Mold moved out and the boiler already in the open mold can be moved into it. While of foaming of the new boiler within the closed mold then becomes the umschäumte Boiler from the side of the mold located moldings removed and replaced by a new to be foamed around the boiler.

Further developments, Advantages and applications The innovation will be apparent from the following description of exemplary embodiments and from the figures. All are described and / or illustrated illustrated features for itself or in any combination in principle the subject of the innovation, independently from their summary in the claims or their dependency. Also, the content of the claims becomes a part of the description.

The Innovation will be described below with reference to the figures of an embodiment explained in more detail. It demonstrate:

1 in a simplified schematic representation and in side view an apparatus for producing the thermal insulating jacket;

2 a plan view of the device of 1 ;

3 in a very simplified schematic representation and in section the boiler of a storage of a heating and / or service water system, together with the boiler on its outer surface enclosing and produced by foaming thermal insulating jacket.

In the figures is 1 a boiler of a hot water tank, for example, the boiler of a cooperating with a heat pump and / or with a solar module heat storage or the boiler of a memory of a plant for providing domestic hot water. With 2 is a made of a foamed plastic, preferably made of hard foam, z. B. consisting of PU foam existing thermal insulating jacket, which in the illustrated embodiment, the boiler 1 on its circumferential or lateral surface 1.1 as well as on its top 1.2 and at its bottom 1.3 completely encloses. In the illustrated embodiment, the insulating jacket 2 in one piece by foaming the boiler 1 produced.

For the production of the insulating jacket 2 or for foaming the boiler 1 serves the in the 1 and 2 schematically illustrated device. This consists essentially of a device frame 4 and a form provided on this apparatus frame 5 into which the respective boiler 1 is introduced for foaming, so then when the mold is closed 5 between the Outer surface of the boiler 1 and the inner surface of the mold 5 an externally sealed mold cavity 5.1 is formed, in which the insulating jacket 2 forming, intumescent plastic material is introduced.

In detail, the form exists 5 from two half-shell-shaped lateral moldings 6 that's in the mold 5 introduced and oriented with its boiler axis in the vertical direction boiler substantially at its peripheral or lateral surface 1.1 surround at a distance and are oriented with the axis of their concave inner surface in each case in the vertical direction, from an upper lid-like molded part 7 which tightly seals the mold space at the top and from a lower mold part or from a lower plate 8th , which is also a stand for the in the form 5 introduced boiler 1 forms and tightly closes the mold space at the bottom.

By appropriate drives are the moldings 6 and 7 motor to open and close the mold movable, namely the two moldings 6 in a horizontal axis direction corresponding to the double arrows A of 2 to close the mold 5 towards each other and to open the mold 5 away from each other and the molding 7 according to the double arrow B of the 1 in the vertical direction to close the mold 5 down and to open the mold 5 up.

A special feature of the device 3 is that the lower molding or the lower pallet 8th is provided at least twice and according to the arrow C in a horizontal axis direction perpendicular to the axial direction of the double arrows A is movable, in each case from a position below the mold 5 in a position laterally of the mold 5 ,

This allows the device 3 a particularly efficient way of working. For example, there is no boiler at start-up 1 in the shape 5 , Rather, a kettle 1 on the side of the form 5 located pallet 8th set up for foaming and prepared. Following this, the boiler is 1 continue on the pallet 8th standing with this palette 8th in the open form 5 introduced, while the other range 8th , which until then in the field of form 5 out of this to the other side of the device 3 is moved. After insertion of the boiler 1 into the mold 5 this is done by closing the moldings 6 and 7 tightly closed, especially at the transition between the on the mold 5 located pallet 8th and the moldings 6 , After that, then in the form 5 located boiler with the insulating jacket 2 forming plastic, preferably plastic foam or PU foam. During foaming may already be on the side of the mold 5 located pallet 8th another kettle 1 be prepared and prepared for foaming.

After expiration of the necessary for the setting of the plastic cycle time, the shape 5 opened and moving the pallet 8th the cauldron standing on this 1 moved into the open mold and thereby the foamy boiler 1 with his palette 8th moved out of the mold. Subsequently, the shape 5 closed again, so that the new, introduced into the mold boiler can be foamed and the foam, ie with the insulating jacket 2 provided cauldron from the side outside the mold 5 removed pallet removed and another boiler can be placed on this pallet and prepared for foaming.

In order to achieve the required foaming and setting of the plastic in the shortest possible cycle or cycle times, the shape 5 heated, ie, for example, on the moldings 6 electrically heated or by a warm heat-carrying medium flowing through heating coils or heating elements are provided.

The moldings 6 are interchangeable to the shape 5 to adapt to boiler of different sizes and / or insulating jacket 2 To be able to produce with different outer surface, such as insulating coats 2 , which are formed on its lateral surface, as shown, polygonal-shaped, ie have a square cross section or are formed circular cylindrical.

The device is preferred 3 Component of a system which has a plurality of such devices, which are then supplied, for example via a charging system with the plastic used for foaming.

Assign the kettles 1 for example, on its peripheral or lateral surface 1.1 over this lateral surface wegstehende sleeves or flanges 9 up, that's the shape 5 preferably designed so that these flanges or sleeves sealed against the inner surface of the mold 5 abut so that the ends of the sleeves or flanges 9 remain free after foaming, but at least remain visible and can be easily exposed in a post-processing in the necessary manner.

The Innovation has been described above in one embodiment. It is understood that numerous changes and modifications are possible, without thereby the inventive idea underlying the innovation will leave.

So it was assumed above that two pallets 8th are provided. Basically, you can also have more than two pallets 8th used and / or the at least two pallets 8th be combined to a multiple pallet or a multiple molding, which then at least two shots for each one boiler 1 forms.
