Definitions

  • the invention relates to a multi-part chimney system according to the preamble of claim 1 and a method for producing a ceramic pipe for chimney systems.
  • Multi-part chimney systems according to the preamble of claim 1 are known.
  • the connecting pieces of the inner pipes of such chimney systems each have a tongue and a groove, so that the inner pipes lying one above the other can be joined together by the tongue and groove connection.
  • an additional sealing compound is placed in the tongue and groove connection.
  • Chimney systems of this type are suitable as vacuum chimneys, which do not necessarily have to be tight.
  • multi-part chimney systems of the type mentioned are known, in which the connecting pieces of the inner pipes are also joined together by a tongue and groove connection are and connected by means of an outer steel sleeve with an inner rubber part or the like so that they are impervious and prevents leakage of gases between the connectors.
  • High pressure chimneys are generally suitable for temperatures below 100 ° C.
  • the inner pipes or inner shell of multi-part chimney systems consist of individual ceramic pipes with different lengths and pipe inside diameters.
  • the inner tubes are connected by tongue and groove.
  • the seal between the respective tongue and groove is ensured during assembly by means of joint cement. Every joint connection therefore represents a weak point in the interior of the chimney, because the required acid and temperature resistance cannot be guaranteed with joint cement.
  • a ceramic tube with an internal thread formed at one end and an external thread formed at its other end is known.
  • This ceramic tube is used in particular for heat exchangers and is made from a ceramic slip. The undried and unburned cullet is spread so that the threads are cut. From this document it is also known to provide a finished fired ceramic tube with external threads at both ends for a releasable connection. Such pipes are connected to one another by means of sockets containing internal threads.
  • the invention has for its object to provide a multi-part chimney system that can be used both as an overpressure chimney and as a vacuum chimney.
  • a method for producing a ceramic pipe for chimney systems is specified in claim 9.
  • the invention overcomes the disadvantages occurring in the prior art, that is, according to a first embodiment, the threads on an inner tube are introduced at one end on the outside and at the other end on the inside into the ceramic fragments.
  • the individual inner tubes can then be screwed together by means of the thread, with no additional sealing material such as joint cement being required.
  • a lubricant is used to facilitate screwing the inner tubes together.
  • the entire inner chimney shell thus consists of only one material.
  • an inner tube 1 consists of a ceramic body that is pressed and is in a wet state after running out of a press.
  • the cullet or blank has a moisture content of about 17%, while after drying in a drying chamber the moisture content is reduced to 1% or less. After drying, the burning process usually takes place.
  • the inner tube 1 is provided with a sleeve 2 formed on the upper connecting piece, into which an internal thread 4 with a predetermined pitch is cut either when wet or after the blank has been fired.
  • An external thread 6 corresponding to the internal thread 4 is cut into the lower connecting piece of the tube 1, likewise either while the blank is still wet or also after the internal tube has burned.
  • the number of threads of the lower connector 6 can be greater than the number of threads of the internal thread 4.
  • the threads can be cut by pressing them in using a roller, or they can be ground in or screwed in using separate processing machines.
  • FIG. 2 shows the lower connecting piece 14 with respect to the inner tube 10 and the upper connecting piece 16 with respect to the inner tube 11 located below it.
  • the inner tubes 10, 11 are provided with a matching external thread 17, 18.
  • the end edges of the inner tubes 10, 11 are straight and can maintain a gap with one another, which can be filled in by an annular seal, even if this is not shown in FIG. 2.
  • the sum of the heights of the threads 17, 18, that is to say the sum of the thread heights of the assigned external threads, is preferably greater than the width or the height of the internal thread of the sleeve 19.
  • the sleeve 19 can consist of the same material as the inner tube 10 or 11 or of plastic.
  • FIG. 3 shows a detailed sectional view in the area of the sleeve 19 or in the connection area between two adjacent inner tubes.
  • the end edges 22, 23, that is to say the lower end edge 22 of, for example, the inner tube 10 and the upper end edge of the inner tube 11 located underneath, are conical, as a result of which condensed water escapes, which runs down the inner walls of the tubes 10, 11. is prevented beyond the connecting surfaces 22,23.
  • the use of an additional 0-seal, as described in the embodiment according to FIG. 2, can be superfluous.
