Definitions

  • the invention relates to a device for the interchangeable installation of operating elements directed into the interior of a reaction vessel in the manner of expansion guide nozzles of air blast devices according to the preamble of claim 1.
  • Bearable downtimes can only be achieved through a special choice of materials or through the choice of special material combinations.
  • types of material used for example when using ceramic elements or with special surface coatings, there is a particular sensitivity to mechanical influences, such as can occur in the described exemplary embodiment of expansion nozzles when installing and removing the corresponding operating elements.
  • BE-A-623 096 shows a device in which a frame is arranged around an opening in a wall, on which a closure plate can be mounted.
  • This end plate has an open flange for inserting thermocouples and is closed from the inside by a spring-loaded mechanism so that it can be opened using a lever.
  • EP-A-82 365 shows that an opening in a wall is closed by means of a flange having a pipe leadthrough.
  • thermocouple and the fuel supply pipes are installed at fixed locations that will not be changed later.
  • These previously known devices do not take into account the problem that, during construction, it is often not possible to estimate exactly where in the later operating state the operating elements, i.e. the expansion nozzles must be attached. Thus, if the previously known devices were used, the boundary walls would have to be broken up again in order to install further expansion guide nozzles.
  • the object of the invention is to provide a device for the interchangeable installation of operating elements directed into the interior of a reaction vessel in the manner of expansion guide nozzles of air blast devices which, when the inner lining of the reaction vessel is built up, the subsequent exchangeable installation of operating elements directed into the interior of a reaction vessel in Art of expansion guide nozzles of air blast devices without further major conversions, whereby not only a good adjustment and careful assembly of these operating elements should be possible, but the device should also be adaptable to different wall thicknesses of the corresponding reaction vessels.
  • the wall of the reaction vessel when the wall of the reaction vessel is bricked up, locations can already be predetermined which can later be used without any problems for the use of expansion guide nozzles.
  • the masonry takes into account the closure elements, which can be accommodated at various points during the masonry and can also be sealed very easily during the masonry, so that the closure elements can be removed at a later point in time and the expansion guide nozzles used.
  • it is no longer necessary to break open the wall of the reaction vessel at a later time, which normally has to be done from the inside and is associated with a corresponding outlay.
  • these measures can also be used to easily replace worn components.
  • Another advantage is that an adaptation to different wall thicknesses is easily possible via the webs on which the shaped block or the pressure plates are arranged.
  • the opening can also be used as an inspection window that can be closed again at any time.
  • the frame is part of a box part which is supported with an inner frame on the inner wall of the reaction vessel and protrudes beyond the outer wall of the reaction vessel and ends there in a flange on which the end plate is detachably mounted.
  • the box part can be used as an inspection window, which can be closed in a suitable manner.
  • a preferred embodiment of the invention consists in that the operating element is accommodated in an insert block provided with an opening for receiving it for installation in an opening provided in the boundary wall of the reaction vessel.
  • the insert stone is connected to the lining of the reaction vessel and preferably consists of a material similar to that of the other stones of the lining, or even expediently of a material that is even more wear-resistant.
  • masonry 2 is listed within a sheet steel shell 1, which forms with the sheet steel shell 1 the boundary wall of a reaction vessel, for example a heat exchanger used in the cement industry.
  • a corresponding opening 3 is left in the steel sheet shell 1 and an angle iron frame 4 is fastened around the opening on the outside of the steel sheet shell 1 and has a plurality of screw holes 6 in its flange 5.
  • a molded block 7 is pushed through the opening 3 into the interior of the reaction vessel and is fastened to an end plate 9 with the aid of an anchor iron 8, as is also particularly clearly shown in FIG. 2.
  • This shaped block 7 is fed until the position of its front edge 10 corresponds to the inner boundary 11 of the masonry 2 still to be introduced.
  • the length of the anchor iron 8 to the end plate 9 varies according to the respective masonry wall thickness.
  • the dashed lines I and 11 indicate the limits of a molded insert block that closes a corresponding opening in the masonry 2 and now in turn has an opening that merges into the opening 3 in the sheet steel shell 1, which in turn provides an insert shell piece at this point can be, the outer limits of which coincide approximately with the limits corresponding to lines I, 11 of the insert block, flange connections or the like. Establishing the connection of this insert shell piece to the sheet steel shell. Details are not shown. They arise naturally for the specialist.
  • the masonry 2 is produced in the interior of the reaction vessel, with a separation in the form of a joint between masonry 2 and molded block 7, preferably with the introduction of a refractory Separating layer 13 is provided.
  • the shaped block 7 By conical or pyramid-shaped expansion of the shaped block 7 in the direction of the end plate 9, the shaped block 7 can later be pulled out by loosening the end plate 9 from the angle iron frame 4 to the outside during operation, so that an operating element no longer serving to lock the masonry in Art an expansion nozzle can be used.
  • the inner wall can be correspondingly excluded for receiving the inner frame 31.
  • the box part 32 protrudes a bit beyond the steel sheet shell 1 of the masonry 2 and ends in a flange 33 which is provided with corresponding holes 34 over the circumference.
  • Fig. 4 shows the closing of this frame 30 with the aid of a pressure plate 35, which is connected via a web 36 to an end plate 37.
  • the pressure plate 35 is pressed with its edge onto the inner flange 38 of the frame 30 in such a way that a tight seal is ensured.
  • the box part 32 can be designed to be of any length, there are no difficulties in adapting the device to corresponding wall heaters of the display wall 1, 2. If necessary, appropriate intermediate rings or the like can be used.
  • FIGS. 3 and 4 show the sectional view according to FIGS. 3 and 4 rotated by 90 °. No further explanations are necessary.
  • the reference numerals designate parts that can also be seen from FIGS. 3 and 4.
  • Fig. 6 shows the installation of an operating element, here an expansion nozzle 40, which is welded in a closure plate 41 screwed onto the flange 33 and is supported with its nozzle mouthpiece 42 on the inwardly projecting flange 38 of the frame 30. Again, a clean seal is guaranteed.
  • the expansion nozzle 40 consists of the tube part 43 and the mouthpiece 42 already mentioned.
  • the arrangement can be made such that it is directed into the interior of the reaction vessel at a certain preselected angle.
  • 7 has a preferably rectangular slot 45 for receiving the pipe part 43, the length of which depends on the installation angle. After appropriate adjustment, the pipe part 43 is firmly welded to the end plate 41. The slot 45 for Recording of the pipe part 43 then no longer exists.
  • the opening thus created in the wall can also be used as a pick opening.
  • the cavity which forms in the box part 32 either after the installation of the closure plate 37 or that of the hot-fire expansion guide nozzle 40 with a medium, for. B. to fill with a coolant.
  • tubular elements with a circular or elliptical cross section for the construction of the box 30 and in particular the box part 32.
