Embodiment Construction

[0035] figure 1 An embodiment of an inventive device 1 for heating a material 2 is shown. Material 2 is shown here as a flat surface. The cavity resonator 3 is shown here as a multi-planar hexagon, which is made up of six outer side segments 4 and arranged such that its open side faces the material surface 2 . Generate microwaves 6 (see figure 2 ) microwave source 5 is configured outside the cavity resonator 3 . According to the invention, the wavelength of the microwaves 6 corresponds to at least half the material thickness of the material 2 . Microwaves 6 from a microwave source 5 pass through a waveguide 7, via a microwave entry point (shown here as a window) on the cavity resonator, into the cavity interior as parallel as possible to the material surface 2 . A handle for lifting the cavity resonator 3 is installed on the head side of the resonator.

Abstract

The present invention relates to a device for heating a material, comprising: a cavity resonator (3) which is open towards a material surface (2) to be treated, the cavity of the cavity resonator being formed on the interior of at least one lateral surface (4) and the at least one lateral surface (4) consisting of a material that reflects microwave rays (6); at least one microwave source (5), arranged inside or outside the cavity, for introducing microwaves (6) into the cavity, wherein the microwave source (5) introduces at least some of the microwaves (6) as parallel as possible to the material surface (2) inside the cavity, wherein the geometry of the cavity resonator (3) is selected so that the microwaves (6) emitted from the microwave source (5) and / or reflected by a lateral surface (4) enter the material (2) with as parallel a direction as possible, and wherein the wavelength of the microwaves (6) emitted by the microwave source (5) corresponds to at least half of the material thickness.

Description

technical field [0001] The present invention relates to a device and method for heating materials. Background technique [0002] Microwaves can be used to repair damaged asphalt cladding, such as potholes on roads. The microwaves are applied to the surface to be treated by heating the bituminous material by means of microwaves, as described, for example, in US Pat. From US 5,441,360 A, US 5,092,706 A, US 4,849,020 A it is known to use materials which absorb microwave radiation during the recycling of asphalt cladding. [0003] Similar methods and compositions are also described in CN 101736671 A and CN 101906745 A, wherein the asphalt mixture also contains many other components, such as magnetic powder, iron powder, basalt and silicon carbide. Such a bituminous mixture is described in the inventor's laid-open document DE 10 2015 108 862 B4. This mixture enables optimum heat distribution in the material during microwave treatment. [0004] According to the need for improv...
