Definitions

  • the invention relates to a device for the capsule-free firing of crockery, in particular porcelain and ceramic plates in the tunnel oven, bogie hearth and chamber furnaces, as well as in rapid firing furnaces with one and more focal levels.
  • Burning flatware in the tunnel kiln takes place today in the so-called saving capsules in which the plates at temperatures of about 1400 o C are burned.
  • the weight of the capsules is usually 5 to 8 times the weight of the dishes to be burned. This weight is a major reason why over 7000 kcal / kg are required to burn porcelain plates, while the theoretical heat requirement is only 10% of this value.
  • the loading and unloading of the capsules is very labor intensive, since the capsules must be stacked apart and stacked again.
  • DE-OS 30 06 376 can be seen in close connection with DE-OS 28 17 887.
  • three-eared set plates are also used.
  • the peculiarity is that it is proposed to use a support for two ears of two different set plates. With this system too, a ratio of 1: 1 number of individual columns to set plates is not achieved, but there are always more columns than set plates.
  • DE-OS 23 51 691 which is still cited by the testing agency, relates to kiln furniture in which supports and setting surfaces are a component. Even with this system, a ratio of set plate to individual column number of 1: 1 cannot be achieved when stacking.
  • the object of the invention is to provide a device for capsule-free crockery consisting of set plates and individual supports, which are designed as components separate from the set plates, which allows a further optimized use of space in the oven. At the same time, the weight of the device should be minimized. Finally, the aim of the device according to the invention is to accelerate the loading and unloading of the combustion vehicle and, if possible, even to automate it.
  • each set plate is supported by two individual supports and the ratio of the set plate to the number of individual plates is 1: 1.
  • the individual supports are preferably shaped on their upper and lower sides so that they act as a connecting surface when several supports are stacked one on top of the other. For this purpose, they are preferably provided with locking cams and depressions.
  • the individual supports can have recesses for the set plates. These recesses are designed so that the setting plates are not hindered in their thermal expansion behavior.
  • the cross-section of the individual supports can have different geometric shapes. Triangular, circular, angular, square or rectangular configurations are preferred.
  • the side surfaces can also be curved.
  • the surfaces of the set plates are adapted to the size of the firing material. This adjustment preferably takes place only in the central part of the seating surface, while at the ends the seating surfaces are narrow and shaped so that they can be inserted into the cutouts of the individual supports.
  • This construction method achieves optimal weight savings.
  • the number of supports of the device according to the invention can be adapted to the respective requirements, a set plate always being carried by two supports and the ratio of individual supports to set plates in one plane always being 1: 1.
  • the device must therefore consist of at least three set plates and three individual supports.
  • the devices according to the invention preferably consist of three to six set plates and three to six individual supports in one plane. According to the invention, a device is particularly preferred in which three or four set plates are placed on three or four individual supports.
  • the advantage over the devices known from DE-OS 28 17 887, 30 06 376 and 23 51 691 is that the number of supports corresponds to that of the setting surfaces if more than three setting plates are used. Accordingly, only three supports are required for three seating surfaces or only four supports for four seating surfaces, whereas in the stated prior art at least six or eight supports would be necessary. The consequence of this is a considerable weight saving compared to the previously known devices. The weight saving increases with the number of set plates inserted in the furnace. Because the individual supports are shaped in such a way that they can be joined one above the other, several setting days can be arranged one above the other. For the construction of two setting days A total of eight supports are needed for every four plates.
  • the device according to the invention has greater stability than the systems known from the prior art for building up a number of setting days.
  • the combustion chamber capacity can be optimally used through an appropriate arrangement of the combustion material in the system.
  • the individual elements of the system are variable and can always be adapted to the requirements of the firing material. Compared to the cited prior art, up to 25% higher space utilization is made possible.
  • the device according to the invention can also be placed on a beam frame, because the system is suitable for a symmetrical setting method due to the design with only two individual supports per setting plate.
  • the structure on scaffolding enables individual parts of the structure to be removed for loading and unloading.
  • the setting surfaces can be exchanged without great effort, so that only those are used which are adapted to the respective size of the firing material.
  • the system can also be set up on various firing trolleys using scaffolding and various storage spaces. The height of the existing combustion chamber can thus be used several times. The kiln can be used and emptied from various sides.
  • the geometric design of the set plates has the advantage that the Plate deflection on the setting surface is largely avoided even with minimal plate thicknesses. At the same time, it prevents a change in the planimetry in the setting range of the fired material.
  • the device according to the invention can be used in a wide variety of furnace systems. Depending on the use and selection of the ceramic materials for the elements of the device according to the invention, it can be used at temperatures up to 1700 ° C.
  • the device according to the invention enables a setting pattern with regular lines and dots while at the same time making optimal use of space. Since the firing material is also easy to use and empty, the device according to the invention also fulfills the requirements for automated insertion and emptying.
  • the individual elements of the device according to the invention are essentially made of recrystallized SiC, nitride-bonded SiC and mullite-bonded SiC and Al2O3. These products are commercially available under the names Crystar R , Cryston R and Mulnorite R.
  • the technical ceramic grades with special properties that are suitable for the present invention also include conventional bonded silicon carbide and silicon infiltrated silicon carbide grades.
  • the geometric shape of the elements of the device according to the invention and the selection of the suitable technical ceramic quality enable an optimized use of the combustion chamber and a variable design of the installation space. According to the invention, the possibility of working with minimally possible fuel weights is particularly advantageous.
  • the device according to the invention is therefore also suitable for rapid firing conditions.
  • the setting plate thickness correspond approximately to the thickness of the firing material. This ensures a uniform temperature distribution over the cross section of the kiln and an increase in the surface quality of the kiln.
  • FIG. 1 shows an embodiment preferred according to the invention, in which four set plates 2 rest on four individual supports 1.
  • the plates 3 to be burned are located on the set plates 2.
  • the width of the middle part 9 corresponds to the diameter of the contact surface of the plates 3.
  • the width of the set plates 2 tapers towards the two ends.
  • the plates 3 are removed on the sides 4 possible.
  • FIG. 2 shows a further preferred embodiment of the device according to the invention, in which three set plates 2 rest on three individual supports 1.
  • the shape of the set plates 2 and the plate 3 corresponds to the configuration shown in FIG. 1.
  • FIG 3 a preferred embodiment of a support according to the invention is shown in cross section.
  • This support has the shape of a triangle.
  • the locking devices 5 and the recesses 6 are used for the form-fitting, non-displaceable stacking of the supports when building up several set plates.
  • the locking cam 6 is precisely adapted to the recess 6c.
  • the upper (6b) and lower (6a) surfaces can be placed on top of one another in such a way that they act as a shift-resistant connecting surface. In this way, several supports can be placed one above the other without the risk of slipping or other instabilities.
  • the entire cross-section of the furnaces according to the invention can be filled with the device according to the invention.
  • FIG 4 different geometric shapes of the supports 1 are drawn in cross section.
  • the triangular, circular, square and rectangular shapes 1a, 1b, 1c are particularly preferred.
  • the rounded shapes 1d and 1f can also be used.
  • FIGS. 6 and 7 show the geometric shapes of the set plates 2 according to the invention.
  • the shape shown in FIG. 6 is particularly preferred, since on the one hand the setting plate 2 and the size of the firing material are optimally matched to one another and on the other hand the setting plate bending is prevented.
  • Optimal weight savings are achieved with the shape shown in FIG. 7.
  • the ends 8, which are inserted into the recesses 7 of the supports 1, are considerably narrower than the setting surface 9 adapted to the firing material.
  • FIG. 10 shows the cross section of a furnace in which the device according to the invention is housed.
  • the number of set plates 2 is only determined by the set height 11.
  • the setting height 11 in turn depends on the height of the firing material.
  • the supports 1 can be varied depending on the firing height. With the device according to the invention, the furnace can be filled with firing material in its full width and height.
