Description

Retort made of molded bricks for gas generating furnaces Retorts for Gas generating furnaces are either made in one piece or they are made from individual shaped stones. These shaped stones range in length from one Support pillars to the next and correspond in their width to a piece of the oval Retort cross-section. Accordingly, the outside and inside broad sides of the Curved shaped stones. The production of such pieces is callous and requires a great deal of time and work. The pieces .must, not only be made in a shape corresponding to their shape, z. B. by Applying the malleable, refractory mass or by pulping unformed or only visually awake, refractory masses in the form, but -you also have to dried in their molds so that they retain their exact shape. 'Through this a large number of molds is required and a large drying area is required. In addition, the drying progresses only slowly, since the shaped piece is only one-sided exposed to dry air.

When building the retorts from arcuate pieces, you need them also curved support surfaces. This means that the stones of the support pillar, which carry the retort are equipped with finite arched support surfaces have to. The bearing stones designed in this way require complex ones again for their production and therefore expensive molds. It must also be an accurate Adaptation of the Arch shape of the retort piece on the arched support surface of the support stone to be available.

In order to bring about a simpler support of the retort pieces, has the retort pieces, as far as they rest on the supporting stones, are straight Provide support surface. But this stopped the production of the retort pieces even more difficult and the forms of manufacture even more intricate.

According to the invention, the retorts are built from stones that only have straight surfaces. The straight shaped stones lined up in a row. give the retort a cross-section that approximates the oval. The stones can be in simply designed shapes and made to dry on the usual drying boards be placed. The drying areas can be occupied more densely and the stones during before drying. This significantly shortens the drying time.

The previously common retort pieces were in the cross section of the retort put together with tongue and groove. The tapered feathers in particular broke when the stones are dried and when they are placed in the kiln. Self the feathers, which had become hard as a result of the burning, usually still broke in pieces when transporting the stones. Stones damaged in the tongue or groove could be because of this resulting leakage of the retort cannot be used for its construction. The failure of shaped stones was therefore very high, especially with stones made of silica mass, whose grooves and tongues are very sensitive to breaking.

According to the invention, each shaped block is given on the side abutting surfaces a horizontal contact surface and a vertical contact surface. As a result, everyone lies upper stone on the lower in a direction natural to the building up and on. Pointed edges and thus diagonally directed pressure effects, which result in heating the expansion of the fabric, especially with silica material, breaks at the joints which cause stones are avoided. The horizontal upright and the vertical Contact surfaces extend in order to avoid sharp corners and weak ones Do not place the entire abutment surfaces in the axial direction. You «- just earth Made so big that it can be put on and put on well. The rest of the c Part of the abutting surfaces is given a delimiting surface lying in the axial direction.

In this way, only a few stone shapes are required. Choose z. B. a division into eight pieces, the cross-section can be formed from three stone shapes because the lower stone and the upper stone are the same, as are the two perpendicular standing side stones. Furthermore, the stones in between are the same.

Accordingly, three forms can now be used that are less sensitive to breaking off Make retort pieces that transmit pressure naturally in your stone structure Can be strung together and which do not require any special molds for drying.

curse conical retorts can be built with such stones. Only the lower or upper stone needs something according to the conicity to be made narrower. If the distance between the piers is short, you can use less Conicity z @ yei pillar distances with the same upper and lower stone occupy. If the distance between the pillars is greater, all lower and upper stones are always in place to make it a little narrower. Each upper or lower stone can use its whole Be the same width across the length. The conicity of the retort is obtained by laying one behind the other narrower upper and lower stones in the longitudinal axis of the retort. Become protrusions avoided by compensating in the joints.

The retort pieces lying one behind the other in the longitudinal axis are connected to one another by overlapping, so that despite the linear expansion a good sealing is possible.

The retorts can be laid horizontally or at an angle.

The drawing illustrates the invention.

Fig. I shows a cross section, Fig.2 a longitudinal section through the Retort.

The retort, which is oval after the arc line a in the () animal section, is from the Bricks b erected only with flat surfaces. These shaped stones are on the arc line a. The number of stones closing the oval or their cross-sectional length is chosen so that the oval I'-etortenforin is largely granted.

To ensure that each person can be rested comfortably and safely supported Every shaped stone is given to achieve retorting stones on top of each other or against each other a horizontal support surface on the abutment surfaces in the retort cross-section i and a vertical contact surface 2. The remaining part of the abutment surface can then be in run in the axial direction.

The butt surfaces of the molded blocks lying in the longitudinal direction of the retort get the leaf-shaped ;. Overlap 3.

PATENT CLAIMS: i. Constructed from shaped stones, essentially in cross-section round or oval retort for gas generating furnaces, characterized in that each Shaped stone is designed as a plate with -even inner and outer surface and that the inner surfaces of the stones are correspondingly smaller than the cross-section of the Rztorte the outer surfaces. 2. Retort according to claim i, characterized in that the abutment surfaces the plates are provided with horizontal and vertical support surfaces. 3. Retort according to claim i and 2, characterized in that the abutting surfaces lying in the longitudinal axis are overlapped in a sheet-like manner.
