Abstract

Chimney pipe for the lining of household and industrial chimneys, which consists of vitrified, thin-walled ceramic.

Description

FIELD OF THE INVENTION The present invention relates to a liner pipe for lining household and industrial chimneys consisting of stacked pipe pieces.

Usually, two types of lining pipes are used for lining masonry chimneys, either chamotte pipes or stainless steel pipes. Chimney tubes can only be manufactured over a minimum wall thickness of about 20 mm, so they are relatively heavy. The high wall thickness and heavy weight are not only disadvantageous for processing, but also because of the need for a sufficiently large chimney to be built for a given internal cross-section. Another disadvantage of chamomile tubes is that they are usually highly porous. However, chimney liners for lining the chimneys should be as tight as possible to ensure that the flue gases are really flowing inside the lining and not come into contact with the exterior masonry, as this will eventually be destroyed by the flue gas. Ultimately, lining is used to avoid this.

First of all, stainless steel pipes are very expensive for chimney liner material. In addition, particularly in the case of fuels containing sulfur or hydrochloric acid, they are prone to corrosion. And because virtually every fuel used, whether coal, wood or oil, contains such impurities, the stainless steel tube, even if its high price is ignored, is in most cases negligible.

It is an object of the present invention to provide a chimney liner that is both lightweight and low wall thickness, but also corrosion resistant and gas tight.

To achieve the above object, the chimney liner pieces according to the invention are thin-walled, solid-fired ceramic masses made of aluminum silicate or cordierite-containing ceramic mass, which are interconnected by means of a push-on snap-on joint.

Such technical ceramic tubes are made of cordierite or cordierite-containing material or alumina-based material with very thin wall thickness and low porosity, and are now antifreeze. In addition, such ceramic tubes are acid-proof and do not threaten to fall below the dew point. The small wall thickness allows for a given internal cross-section to be bricked with a smaller internal diameter chimney, and some pipe sections to be worked on also have significant weight savings due to the small wall thickness, which makes it much more convenient for the chimney builder and installer. develops.

In a preferred embodiment of the invention, the wall of the tube is provided with longitudinal channels, which may be optionally circular or rectangular in cross-section, thereby forming a honeycomb-like wall structure.

Contrary to the known, most commonly used Bamolt pipes, where the high wall thickness allows the grooves of the pipe ends to be filled and filled, even with a special mortar or the like, this type of jointing of the thin-walled ceramic chimney pipes according to the invention is not possible. A newly formed kit is provided for the connection of the chimney pipes to each other by the use of push-on kits or sleeves.

Such kits or sleeves formed in accordance with the present invention consist of two sections of different diameters, the smaller one of which corresponds to the diameter of the chimney boat, and in the extended sleeve section are provided with inwardly extending supports which extend to the front face of the pipe piece.

It is within the scope of the invention that the struts are extruded as tongues printed from the sleeve.

The push-in kits or sleeves according to the invention can be applied to the outside of the tubes in addition to the gap between the adjacent faces of the ceramic tubes, which ensures a good seal in each case. Quartz-poor putty or mortar should be used as a putty, which is used in this context in a non-specific sense, although it may also use special mortars.

Other advantages, features, and details of the invention will be apparent from the following description of an exemplary embodiment, and from the accompanying drawings. The drawing

Figure 1 is a longitudinal sectional view of two sections of superimposed pipe pieces in different insertion positions on the right and left, while

Fig. 2 is a plan view of a detail of a front face of a pipe piece with a schematic representation of the various lengths of the tower.

Figure 1 shows the joining positions of two superposed pipe pieces 1 according to the invention. Each of the pipe pieces 1 forming the chimney liner is made of a compactly fired thin-walled technical ceramic material, for example containing 50-80% AliOs, ceramic mass, extruded and conventionally fired. The pipes may be round or angular in cross-section, according to the requirements in each case. It is particularly easy to manufacture these liner pieces because they are all of the same cross-section, with no need for groove, nail or other joints at their ends. A quartz-poor mortar or kit is used to connect the superposed ceramic mirrors 1, while in accordance with the invention, an additional element, the filler sleeve 2, is used. This clamping sleeve 2 comprises two sections 3 and 4 of different diameters, the inner diameter and the inside diameter of the smaller diameter section and the smaller inner section section 3 5 corresponding to the outer diameter and the outside dimension of the pipe piece. In the larger sleeve section 4, the supports 5 are formed as bent press tongues. These supports 5 are always supported by the upper end face 6 of the lower tube piece 1 from the pipes to be connected. In this way it is ensured that the gap 8 between the pieces 1 is bridged by the wider section 15 of the socket 2, this section also includes a transitional conical section 7, so that when the pieces 1 are pressed, the kit 9 is pressed not only into the gap 8. but covers the side and bridges the entire 20 gaps (right side of Figure 1).

Fig. 2 is a schematic view of the front face 6 of the gutter piece 1, showing the possibilities of forming different passageways 10, 10 'and 10' on one and the same tube. Through these longitudinal channels, further weight reduction of the ceramic liners is achieved.
