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 subsequently change, existing furnaces can usually be adapted only with disproportionate effort, very often must be invested in new stoves.
  • 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.
  • US-A 4,300,882 discloses a modular wall system for industrial furnaces having a plurality of thermal insulation modules comprising an insulation layer mounted in an outer frame.
  • the components of the state of the art must always be integrated into an individually planned overall furnace construction, which requires relevant expert knowledge and makes the overall furnace construction expensive and expensive.
  • 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 furnace module, so that even demanding tasks with regard to targeted and homogeneous heat input and temperature control can be solved without difficulty.
  • a housing frame 5 made of steel specifies an outer basic module dimension.
  • the housing frame 5 has four-sided circumferential connection points 6, via which the connection to the housing frame 5 of adjacent modules.
  • the housing 5 serves as an outer "support corset” for fixing inside module components such as heating 2 and temperature sensor 1, mounting the heating elements 3 and a heat-resistant heat insulating layer 4.
  • the housing frame 5 forms a cavity on the outside, in the electrical connection elements, such as connectors 8 for the heater. 2 and temperature sensor 1 are housed.
  • the cavity for the electrical connection elements is closed from the outside by a cover 7 for the contact protection.
  • the heat-resistant thermal insulation layer 4 is frictionally connected to the outer housing 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 heat insulating layer 4 establishes the constructive connection to the holder 3 of the heating devices 2. Due to the structural design of the thermal insulation layer 4 dimensional stability of the basic module is achieved while minimizing thermal bridges. Via external surfaces of the thermal insulation layer 4 by means of special sealing strips (not shown), the thermal seal to adjacent modules.
  • the heater 2 is metallic and provided with a ceramic holder 3.
  • the metallic heater 2 of spirally wound heating conductor is threaded meander-shaped and constrained on ceramic support tubes and can therefore 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 heat insulating layer 4.
  • the live heating device 2 is electrically insulated from the thermal insulation layer 4 by the ceramic components.
