Definitions
- the invention relates to a chamber or continuous dryer as well Preheater for ceramic moldings made from a base plate thermally insulated sheet metal elements.
- Dryers were originally bricked using the walls both mechanical strength and thermal insulation cause.
- metal structures are increasingly used, which are covered with additional insulation elements.
- Ceramic moldings are usually produced in certain drying sections depending on the rising temperature humid climate. Due to increased temperatures and high humidity forms on cold surfaces of the dryer building, like them e.g. occur at thermal bridges, condensate. This can lead to corrosion of the metallic components and in extreme cases when the Condensate on the dry goods lead to defects in this. Moreover thermal bridges lead to energy losses. Penetrates the condensed Water into the insulating layers, so it affects them Isolability, so that increased condensation take place can. The presents itself as a considerable economic disadvantage Need out, first a metal structure to be carried out, which is subsequently covered, and which is disadvantageous high manufacturing, development and assembly costs.
- US Pat. No. 2,211,644 discloses such a metal construction for a dryer. Here is between two metal plates of insulation material arranged and the metal plates on Border joined together. This sandwich construction also has the Disadvantage that in the edge area of the metal plates by the opposite to the side walls and outwards thermal bridges with the ones described above are curved to the base Disadvantages arise. In addition, in the case of the elements to be attached at right angles, the seal is not clamped between the side wall and the edge strip.
- EP 0 161 133 A already discloses a metal plate with double angled ones Edge areas that are welded at the edge joints.
- the trough-shaped sheet metal elements to be welded on at a right angle, however, they become complex and costly Fasteners set. additionally are stiffening elements to increase the stability of the needs also serve to hold the outer skin, so that here too, corresponding thermal bridges with the disadvantages described above occur.
- the invention has for its object to increase productivity as well as the economy both a reduction in Need for thermal energy as well as an acceleration of the previous one To ensure drying processes, with precise control of the drying process should be guaranteed.
- the required trough-shaped sheet metal elements can be used low assembly effort easy to self-supporting constructions Assemble without additional supporting structures.
- a high Tightness is achieved by screwing them together
- dividing walls stand two walls and, for outer walls, the wall and a cladding at a distance from each other, so that the resulting gaps for Insulation can be easily filled with insulating granulate, e.g. perlite are.
- Ceilings can be easily insulated by insulating layers are applied, if necessary, for example by on-hook Chipboard can be protected mechanically.
- the thermal separation of Inner and outer shells without thermal bridges with filled insulating materials ensures excellent insulation properties and thus minimizing the formation of condensate, as well as a reduction the need for thermal energy.
- To avoid heat loss or heat storage in the dryer floor can be insulating concrete or with more resistant Mineral wool filled or relined metal elements be used.
- Figure 1 is a perspective-schematic of two trimmings showing chamber dryer, the casing only in a small wall area is completed.
- a base plate 1 On a base plate 1 are an outer wall 2, connected to each other trough-shaped sheet metal elements 3 shown.
- a partition 4 is listed, which consists of two rows trough-shaped sheet metal elements opposing each other 3 are created, the space between them by a thermal Insulating layer 5 is formed by filling the space with, for example, perlite, an insulating granulate.
- the ceilings 6 are each made of trough-shaped sheet metal elements 3, the upper, exposed base areas with insulating material, For example, a layer of mineral wool 7 are overlaid are covered with chipboard 8 for their mechanical protection.
- a tub-shaped is enlarged and broken off and interrupted Component 3 shown in Figure 2. It consists of one rectangular base area 14, from the side walls 15 on all sides are turned, from their end regions in turn edge strips 16 are folded. The joints of the side walls 15 and the edge strip 16 are gas-tight by a weld seam 17 connected with each other.
- the trough-shaped sheet metal elements 3 in their length corresponding to the dryer height. So are for example, in FIG. 3 two trough-shaped sheet metal elements standing side by side 3 shown, the height of which corresponds to that of the dryer.
- the width of the side walls 15 as well as the edge strips 16 as well the sheet thickness used depends on the static requirements. One becomes expedient as cover or wall elements Use sheet metal elements 3 of the same dimensions. It is also possible, for example.
- the sheet metal elements 3 for the ceiling 6 of their higher Bending stress due to larger sheet thicknesses, but especially with higher widths of the side walls or edge strips.
- the side walls act on the bending loads imposed on them as profile yokes and the edge strips as lower profile straps.
- FIG. 4 A somewhat more than half cross-section is shown in FIG. 4. From trough-shaped sheet metal elements 3 with the length of the height of the Dryer, an outer wall 2 and partitions 4 are created, and also the ceiling 6 is formed by trough-shaped sheet metal elements 3. in the The partition is at a distance of approximately 100 mm from the partition 4 of the second stocking aisle 9, and at an appropriate distance from the Outer wall 2 is a casing 11 formed from trapezoidal sheets 12 intended. The gaps formed are one poured perlite or mineral wool insulating layer 5 executed. The trough-shaped provided as ceiling 6 Sheet metal elements 3 are also made of an insulating layer, here Mineral wool 7 formed, covered and for their mechanical protection Cover with chipboard 8 or perforated sheets. The base plate 1 continues to contribute rails 10 on embedded support profiles Pickup of a dryer car.
- the installation of the walls on the base plate 1 is enlarged and shown broken off in Figure 5.
- the bottom plate 1 is with a embedded mounting rail 19 equipped.
- the mounting rail 19 is aligned and used before the base plate 1 is cast as a pulling aid. This results in a flat surface 20 on which can be optimally worked and assembled.
- the mounting rail 19 forms the interface to the dryer body.
- With the mounting rail 19 is connected a U-shaped folded sheet 21, which is equipped with seals 22.
- Against the legs of the profile sheet 21 are the lower regions of the trough-shaped elements 3 of the partitions 4 leaned; they are supported on the mounting rail 19 from. They are connected to the legs of the profile sheet by sealing screws 23 which hold the mounting rail 19 firmly connect to the trough-shaped sheet metal elements 3.
- connection between the ones that function as the outer walls and the ceiling trough-shaped sheet metal elements 3 is also based on the one 6 shows an enlarged section of a cross section seen.
- the sheet metal element forming part of the outer wall 2 3 takes an edge strip 16 of the 6 arranged as a ceiling Sheet metal element 3, with the edge strip 16 of the one sheet metal element towards and to the side wall 15 of the second towards a seal 22 is interposed.
- the figure also shows that for strength reasons the sheet metal element belonging to the ceiling 6 with wider ones Side walls 15 and wider edge strips 16 is executed.
- the trough-shaped sheet metal elements 3 provide one excellent solution for the construction of dryer buildings their side walls 15 can be easily connected to each other.
- the arranged between the sheet metal elements 3, by means of screws 23 compressed sealing strips 22 have an optimal sealing effect. So outer walls 2, partitions 4, ceilings 6 and frontal end walls achieved by easy connectivity cause little assembly effort, and they are self-supporting are, so that additional scaffolding, supporting structures or the like can be avoided.
