Definitions

  • the invention relates to an industrial furnace system with the features of the preamble of claim 1.
  • Furnaces and thermal equipment are used in almost all areas of industry and research for thermal processes.
  • the breadth of use of these systems penetrates almost all industries and processes in the manufacture of products. This results in a variety of furnace designs and technologies. Prefabricated standard solutions are in this case inapplicable. It is often required a very specific approach to the task at hand, which is associated with a high development and engineering effort for the manufacturer.
  • the end user when acquiring such a furnace, the end user must consider how the size and power capacity of the plant should be designed not only for current needs but also for possible future requirements. Not infrequently, this equipment oversized, which leads to unnecessarily high space and energy requirements. If technical or dimensional requirements change later on, existing furnaces can usually only be adapted with disproportionate effort; very often it is necessary to invest in new furnaces.
  • document EP 72081 A1 discloses, for example, an insulating module for use in an electric furnace of a refractory fiber mat of discrete refractory fibers bonded together with an inorganic binder.
  • the module has a hot side, a cold side, and a variety of side surfaces.
  • a plurality of individual ceramic carriers are partially embedded in the mat and protrude from the hot side to the outside.
  • the embedded ones Sections are firmly anchored in the mat.
  • the protruding portions support an electrical resistance heating band inside the furnace.
  • the fiber layers build on a lower panel in planes perpendicular to the hot side of the module.
  • DE 3326463 discloses electrical hot plate modules with a stable support frame of refractory stone material. Support tubes in a fiber core form a lightweight, stable and versatile electric hot plate module.
  • the object of the invention is to provide an industrial furnace system with which the disadvantages of the prior art are avoided.
  • At least one heater and electrical connection elements are used for heated wall modules.
  • the system is also preferably supplemented functionally by the provision of likewise modular measurement, control and control units. These make it possible to individually control and regulate each heatable oven module, so that even demanding tasks with regard to targeted and homogeneous heat input and temperature control can be solved without difficulty.
  • a module housing frame 5 made of steel specifies an outer basic module dimension.
  • the module housing frame 5 has four-sided circumferential mounting points 6, via which the connection to module housing frame 5 of adjacent modules takes place.
  • the module housing 5 serves as an outer "support corset” for fixing inside module components such as heater 2 and temperature sensor 1, holder of the heating elements 3 and a heat-resistant, thermally insulated inner cassette 4.
  • the module housing frame 5 forms a cavity on the outside, in the electrical connections, such as Connectors 8 for the heater 2 and temperature sensor 1 are housed.
  • the cavity for the electrical connections is completed from the outside by a cover 7 for the contact protection.
  • the heat-resistant, heat-insulated inner cassette 4 is frictionally connected to the outer frame 5 and serves to enclose and support an internal insulation structure of the basic module.
  • the insulation structure is optimized in terms of good thermal insulation and low heat storage capacity.
  • the inner cassette 4 establishes the constructive connection for holding the heating elements 3. Due to the structural design of the inner cassette 4 dimensional stability of the basic module is achieved while minimizing thermal bridges. About outer surfaces of the inner cassette 4 by means of special sealing strips (not shown), the thermal seal to adjacent modules.
  • the heating element 1 is metallic and provided with a ceramic holder 3.
  • the metallic heating element 1 of spirally wound heating conductor is threaded meander-shaped and constrained on ceramic support tubes and can thereby radiate its heating energy intensive and evenly free.
  • the ceramic support tubes are in turn received by a circumferential ceramic frame, which is joined at the corners by connectors and connected to the inner cassette 4.
  • the live heating element 1 is electrically insulated from the inner cassette 4 by the ceramic components.
