Definitions

the invention relates to a furnace for heat treatment of a plurality of articles. Furthermore, the invention relates to a furnace with a plurality of ovens.
the heat treatment of grinding wheels takes several hours at temperatures above 200 ° C. Such a heat treatment causes high energy consumption since not only the grinding wheels but also the parts of the furnace absorb heat during heating. Most of the furnace parts are relatively heavy in the heated area of the furnace and have a high heat capacity.
the oven has a vertical combustion chamber, which is equipped from below. This furnace has a relatively high energy consumption due to its structural design.
the essence of the invention lies in the fact that the supporting function in the furnace is taken over exclusively by the support frame.
the heating chamber and the combustion chambers can be designed to be particularly thin-walled. This causes a low heat capacity of the heating chamber and the combustion chambers, so that the heating chamber and the combustion chambers absorb relatively little heat during operation, resulting in a significant energy saving.
the at least one heating element can be arranged within the heating chamber and / or the heating chamber upstream and / or downstream. Alternatively or additionally, the heating element or elements can also be arranged in the combustion chambers or in the region of the covering hoods.
the support framework is thermally decoupled from the heating chamber and from the combustion chambers. This leads to a further significant energy savings, since greatly reduced thermal bridges exist between the support frame on the one hand and the heating chamber and the combustion chambers on the other.
the heating chamber and the combustion chambers can be fastened to the support frame at least indirectly via a plurality of thermal insulation elements.
the thermal insulation elements are made of a high temperature insulating plastic.
the walls of the heating chamber and / or the combustion chambers are at least partially provided with a thermal insulating material. As a result, a heat transfer from the heating chamber and the combustion chambers to the environment is prevented or at least significantly reduced.
the heating chamber and the combustion chambers can be made in lightweight construction.
the lightweight construction causes a particularly low heat capacity and thus a low heat absorption of the heating chamber and the combustion chambers. This results in a further substantial energy saving.
the oven is provided for the heat treatment of disc-shaped objects, in particular grinding wheels.
the grinding wheels are stacked in the combustion chambers.
the cross section of the combustion chambers is adapted to the contour of the grinding wheels.
the oven has a plurality of mandrels for stacking the disc-shaped objects.
the mandrels are arranged one above the other in the vertical combustion chambers or side by side in the horizontal combustion chambers or introduced. This allows a predetermined amount of grinding wheels already outside with the mandrel of the oven. Subsequently, the mandrels can be introduced into the combustion chambers of the furnace "in packages" with the grinding wheels.
the mandrels are made in lightweight construction.
the mandrels have a particularly low heat capacity and thus a low heat absorption. This also contributes to energy savings.
the heating element is arranged in an upper region of the vertical heating chamber.
the heating element of the heating chamber can be upstream or downstream.
the heating element is designed as an electrical heating element.
all kinds of heating such as steam, oil, gas, thermal oil carriers, etc. are possible.
the geometric shape of the combustion chambers can be adapted to the geometric shape of the objects, so that the distance between the objects and the walls of the combustion chambers is uniform. It can be formed between the objects and the walls of the combustion chambers at least one air duct with a uniform cross-section. As a result, less air masses for the required heat exchange must be moved.
the blower can be made relatively small, which also causes an energy saving.
the invention relates to a furnace with a plurality of ovens described above.
the ovens are arranged side by side and coupled to each other by means of hot air ducts and cold air ducts, so that a direct or indirect heat exchange between cooling and heating ovens is made possible. Again, this is a major contribution to saving energy.
Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.
FIG. 1 Figure 3 is a perspective view of a furnace according to a preferred embodiment of the invention.
the oven is intended for heat treating a variety of items.
the oven comprises a support frame 10, which is formed as a three-dimensional frame.
the support frame 10 is substantially in the form of a cage.
the oven further includes a heating chamber 12 located within the support 10 in the center thereof.
the heating chamber 12 is elongated and vertically arranged. In this example, the heating chamber 12 has a round cross section.
the heating chamber 12 around a plurality of combustion chambers 14 is arranged.
the combustion chambers 14 are also elongated and arranged vertically. In this example, eight combustion chambers 14 are evenly distributed around the heating chamber 12.
the combustion chambers 14 have a round cross-section.
a base plate 16 At the lower ends of the heating chamber 12 and the combustion chambers 14 is a base plate 16.
the base plate 16 is fixed to a lower horizontal frame 18 of the support frame 10. Between the base plate 16 and the lower horizontal frame 18 are thermal insulation elements 26th
the thermal insulating members 26 are made of a material having low thermal conductivity.
the base plate 16 is thus thermally decoupled from the lower horizontal frame 18.
the thermal insulation elements 26 are made of a high temperature insulating plastic.
the upper ends of the heating chamber 12 and the combustion chambers 14 are covered by a cover 22.
the cover 22 is attached to an upper horizontal frame 20 of the support frame 10. Between the cover 22 and the upper horizontal frame 20 are also thermal insulation elements 26, so that the cover 22 is thermally decoupled from the upper horizontal frame 20.
the upper ends of the heating chamber 12 and the combustion chambers 14 are interconnected.
a heating element 28 In this embodiment, this is an electric heating element, which is arranged in the upper region of the heating chamber 12.
the combustion chambers 14 are provided for receiving the plurality of articles subjected to the heat treatment.
a blower 24 is arranged below the base plate 16.
it is a radial fan whose axis of rotation is arranged vertically.
the fan 24 conveys the heated air from the heating element 28 from the heating chamber 12, so that the air moves in the heating chamber 12 from top to bottom. Subsequently, the heated air is blown from the fan 24 into the combustion chambers 14, so that the air in the combustion chambers 14 moves from bottom to top. In the combustion chambers 14, the heat treatment of the objects takes place. Under the cover 22, the air from the upper combustion chambers 14 returns to the heating chamber 12.
the support frame 10 forms the supporting part of the furnace.
the heating chamber 12, the combustion chambers 14 and the cover 22 can be made in lightweight construction, since they need not have any supporting functions.
the lightweight design allows a low heat capacity, so that the heating chamber 12, the combustion chambers 14 and the cover 22 absorb little heat.
the heating chamber 12 and the combustion chambers 14 are made of a special flexible tube having a wall thickness of 0.13 mm. This is possible because the heating chamber 12 and the combustion chambers 14 have no supporting function.
the support frame 10 with the lower horizontal frame 18 due to the thermal insulation elements 26 of the heating chamber 12, the combustion chambers 14, the base plate 16 and the cover 22 thermally decoupled, so that the support frame 10 with the lower horizontal frame 18 receives little or no heat , This leads to a significant energy saving.
the furnace is provided for heat-treating resin-based abrasive wheels.
the grinding wheels are made with phenolic resin. By the heat treatment the grinding wheels are hardened.
the round grinding wheels are stacked in the combustion chambers 14, which have a round cross-section. The cross section of the combustion chambers 14 is thus adapted to the shape of the grinding wheels to be treated.
the heating chamber 12 and the combustion chambers 14 are covered with an insulating material.
the insulating material is made for example of rock wool or glass wool and laminated on the outside with an aluminum foil.
the insulating material has a thickness of 100 mm to 150 mm. This also contributes to the saving of energy.
FIG. 2 shows a top view of the oven with a removed cover 22 according to the preferred embodiment of the invention.
a cover plate 30 At the upper ends of the heating chamber 12 and the combustion chambers 14 is a cover plate 30.
the cover plate 30 is the same as the cover 22 by means of the thermal insulation elements 26 attached to the upper horizontal frame 20 of the support 10. Thus, the cover plate 30 is thermally decoupled from the support frame 10.
the electric heating element 28 is mounted in the upper region of the heating chamber 12.
the heating element 28 can be dismantled without great effort for maintenance and repair purposes.
the heating chamber 12 has a protective grid 32 for the heating element 28.
the combustion chambers 14 each have at the upper end a centering element 34 for the central positioning of the grinding wheels.
FIG. 3 is a perspective detail view of a lower portion of the furnace according to the preferred embodiment of the invention shown.
FIG. 3 in particular shows the thermal decoupling between the support frame 10 on the one hand and the heating chamber 12 and the combustion chambers 14 on the other.
the detail view in particular shows the thermal insulation element 26 which is arranged between the base plate 16 and the lower horizontal frame 18.
the thermal insulating member 26 is as L-shaped section formed.
the thermal insulating member 26 is made of the high-temperature insulating plastic.
FIG. 4 shows a front view of a furnace with multiple furnaces according to the preferred embodiment of the invention.
the ovens are arranged side by side.
FIG. 4 the arrangement of the heating element 28 in the upper region of the combustion chamber 12 can be seen.
the grinding wheels are arranged. A certain number of grinding wheels are first stacked on a mandrel 40. Several such mandrels 40 are inserted from below into the combustion chamber 14. In this example ten mandrels 40 per combustion chamber 14 are provided.
FIG. 4 the arrangement of the blower 24.
a motor 42 for driving the fan 24 is located below the blower 24th
the adjacent furnaces are coupled to each other by means of a hot air duct 36 and a cold air duct 38.
This warm air is transported from a just-cooling oven in a straight oven to be heated. This also contributes to energy savings.
FIG. 5 shows a top view of the oven with multiple furnaces according to the preferred embodiment of the invention.
the kiln plant has five ovens.
FIG. 5 illustrates in particular the arrangement of the hot air ducts 36 and the cold air ducts 38.
FIG. 6 Figure 3 is a perspective view of a mandrel 40 for the oven according to the preferred embodiment of the invention.
the mandrel 40 is provided for stacking a predetermined amount of grinding wheels.
the mandrel 40 includes a vertical tube 44 and a round base 46.
the base 46 is composed of an outer ring and a plurality of spokes.
the heat capacity of the mandrel 40 is therefore low. When heating the mandrel 40 takes up little heat, which also contributes to energy savings.
centering elements 34 are provided for the central positioning of the mandrels 40 within the combustion chambers 14.
