Definitions

  • the invention relates to a multi-part chimney system consisting of an outer shell, an inner tube and, if appropriate, an insulation layer inserted between the outer shell and the inner tube and each having a connection piece formed at the lower end of the upper inner tube and at the upper end of the subsequent lower inner tube.
  • Multi-part chimney systems according to the type mentioned are known per se.
  • 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.
  • Such chimney systems are suitable as vacuum chimneys, which are not mandatory 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 and are connected by means of an outer steel sleeve with an inner rubber part or the like so that they are impervious and an escape of gases between the fittings is prevented.
  • 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.
  • 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.
  • each inner tube has at least one connector with an external thread.
  • each lower connector has an internal thread and each upper connector of each inner tube has an external thread.
  • each inner tube has both an upper and a lower connection piece with an external thread, such that two associated inner tubes can be connected at their connecting points by means of a sleeve.
  • the internal thread is cut into a sleeve section, which in each case closes off the upper connecting piece of an inner tube.
  • the inner pipes to be connected can be screwed together without the need to use joint cement or the like.
  • the threads on an inner tube are introduced at one end outside and at the other end 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 O-seal, as described in the embodiment according to FIG. 2, may be superfluous.
