Definitions
- the present invention relates to a device for preventing unwanted radiation or for electromagnetic shielding in the application of products with high-frequency radiation, in particular microwaves.
- high-frequency radiation in particular of microwaves for heating, drying, curing and / or other processing of various products
- food industry fruit pieces are gently dried using high-frequency radiation, for example, and processed for further use.
- treatment with high frequency radiation has proven successful.
- curing of pulps e.g. Mineral wool
- a introduced into the mineral wool fiber material, liquid binder is cured by the microwave caused heating by polymerization.
- the products to be treated are introduced continuously or in discrete portions into an applicator in which the application of high-frequency radiation takes place.
- These applicators must have corresponding product passage openings, in particular in the case of a continuous product entry via, for example, conveyor belts or the like. Both for reasons of operational safety and in terms of the most effective use of the radiant power introduced into the applicator, it is undesirable to emit the introduced high-frequency radiation through these openings, so that an electromagnetic shielding of these openings is required.
- the openings can be configured as straight or meander-shaped shafts or pipes, the walls being designed such that they absorb the high-frequency radiation (absorber choke).
- aborber choke An example of such a solution of electromagnetic shielding is shown in EP 0299365 A1. Since such absorber chokes also absorb the corresponding energy with the radiation and heat up, it is necessary to dissipate this energy, which usually takes place by means of water cooling.
- the metallic shaft walls of the openings can be geometrically designed such that they act as blocking filters within the operating frequency range of the high-frequency radiation (loss-free reactance filter).
- Such a blocking filter is e.g. in the article "Doubly Corrugated Chokes for Microwave Heating Systems” by A.L. Van Koughnett and J.G. Dünn in “Journal of Microwave Power", 8 (1), 1973.
- This filter which is based on the geometry of a two-dimensional periodic structure, is well suited for preventing the emission of high-frequency radiation from a shaft-shaped applicator, provided that its aperture width is smaller than half the wavelength in at least one of the two extension directions (eg height) a plane wave at the highest operating frequency.
- the properties of the dielectric that fills the filter shaft must be taken into account.
- a device for the electromagnetic shielding of an opening of an applicator subjected to high-frequency radiation, which uses a blocking filter operating in the operating frequency range of the high-frequency radiation, wherein the device further comprises a mode filter which blocks the modes not damped by the notch filter.
- the mode filter additionally used according to the invention preferably blocks the modes TE mn (m> 0, n> 0) and TM mn (m> 0, n> 0), while the notch filter according to its most common application blocks the modes TE m0 (m> 0 ) blocked.
- the mode filter is designed for this purpose as a shaft of predetermined length with metallically conductive walls.
- This shaft preferably has a rectangular cross-section, wherein at least the narrow side of the rectangular aperture of the mode filter is shorter than half the wavelength corresponding to the maximum operating frequency.
- the tuning of the filter in this regard may change depending on the material to be treated in the applicator.
- the walls of the duct forming the mode filter are smooth. However, the walls may also have a certain surface texture if necessary to achieve the desired blocking and / or damping of modes.
- the mode filter is disposed between the applicator and the notch filter. Consequently, only the modes to be dampened from this are present at the entrance to the barrier filter, this damping being carried out in the manner known from the prior art and the corresponding technical literature.
- the blocking filter can in this case be designed as a shaft of predetermined length, the metallic conductive walls preferably at least partially have a two-dimensional periodic structure in order to achieve the desired damping.
- the notch filter in this case has a rectangular cross-section, with at least one of the wide sidewalls of the notch filter, i.
- the ceiling surface and / or the bottom surface of the shaft on its inside at least partially a two-dimensional periodic structure up.
- the narrow side of the rectangular aperture of the notch filter is shorter than a quarter of the wavelength corresponding to the maximum operating frequency.
- the determination of this wavelength of a plane wave must take into account the dielectric properties of the material passing through the applicator during operation and thus in the barrier filter.
- the barrier filter also has a rectangular cross section, but at least the two opposite wide side walls of the barrier filter, ie, for example, the ceiling surface and the bottom surface of the shaft, on its inside at least partially have a two-dimensional periodic structure.
- the narrow side of the rectangular aperture of the notch filter is shorter than half the wavelength corresponding to the maximum operating frequency of a plane wave, which is again determined taking into account the dielectric properties of the running during the operation of the applicator material.
- the two-dimensional periodic structure preferably extends over the entire inside of the top and / or bottom surface of the duct forming the barrier filter.
- the two-dimensional structure hereby may e.g. consist of metallic conductive pins, which are conductively connected to the inside and form a regular grid. It would also be conceivable to have a periodic structure integrally formed in the respective side walls during manufacture.
- cylindrical pins are used which are conductively attached in vertical alignment to the respective inner surface, e.g. be screwed on.
- the attenuation a s of the mode filter is adapted such that it matches the attenuation of the notch filter for the lowest mode to be blocked substantially.
- the attenuation of the mode filter a s in this case is adjusted such that the attenuation of the mode filter for the mode TE01 substantially coincides with the attenuation of the notch filter for the modes TE m0 (m> 0).
- the attenuation of a s ⁇ damped TE mn modes in the mode filter length (m> 0, n> 0) and TM mn (m> 0, n> 0) can be used in this context, on the basis the damping of the mode TE 0 - I , which has the lowest limit frequency of all modes to be damped in the mode filter, can be estimated by the following equation:
- ⁇ for the damping constant of the mode filter, and ⁇ ⁇ for the operating frequency corresponding wavelength of a plane wave, taking into account the dielectric properties of befindlichem in the barrier filter material.
- ⁇ £ / h denotes the ratio of this wavelength ⁇ ⁇ to the narrow side h of the aperture of the cross section of the mode filter in the case of a rectangular shaft cross section.
- the length of the mode filter is dimensioned according to a preferred embodiment of the invention such that the determined according to the above equation attenuation a s is approximately equal to the attenuation a f of the notch filter for the modes TE m0 (m> 0).
- the length / of the mode filter is selected as a function of the desired attenuation a s of the mode filter, the narrow side h of the aperture of the cross section of the mode filter and the wavelength ⁇ ⁇ corresponding to the operating frequency that the relationship
- the modes not dampened by the notch filter and consequently blocked according to the invention by the mode filter usually carry only a fraction of the power introduced into the applicator.
- a relatively high power level of high-frequency radiation exists within the mode filter, since, for example, at least one of the modes TE m0 (m> 0) can propagate unimpaired in the mode filter.
- the mode filter when the applicator is used with continuously introduced products, to form part of the effective range of the applicator used to act on the products with high-frequency radiation. In this way, it can be ensured that, when using a mode filter according to the invention for the effective shielding of electromagnetic radiation, the entire length of the applicator only becomes insignificantly longer.
- the device according to the invention for the electromagnetic shielding of an opening of an applicator subjected to high-frequency radiation is adapted with respect to its geometrical dimensions dependent on the operating wavelength taking into account the dielectric properties of the material arranged in the device such that a shielding according to the invention is produced during operation of the device Applicator with high-frequency radiation in one of the ranges 2400 - 2500 MHz, 433.05 - 434.79 MHz, 890-906 MHz, 902 - 928 MHz or 5725 - 5875 MHz.
- Fig. 2 a partially broken horizontal plan view of the embodiment of FIG. 1,.
- FIGs 1 and 2 show the inventive device 1 for electromagnetic shielding in conjunction with an applicator 10th
- the applicator 10 has an inlet opening 11 for receiving the product 4 to be acted upon in its interior by high-frequency radiation.
- the product 4 to be treated in the applicator 10 is a layer of lightweight, lossy dielectric (e.g., mineral wool) in the illustrated embodiment.
- This product 4 is intended to be heated by the power introduced by means of high-frequency radiation in terms of volume.
- the product 4 is introduced into the applicator 10 in the direction indicated by the arrow T by means of a transport device, not shown, transported through the latter along a transport path and finally discharged at the other end of the applicator 10 via a corresponding outlet opening.
- This outlet opening is presently also provided with a device according to the invention.
- the applicator 10 can in this case have any dimensions and is limited by a metallic conductive shell.
- the device 1 consists of the mode filter 2 adjoining directly to the inlet opening 11 of the applicator 10 and the blocking filter 3, which adjoins the mode filter 2 directly, ie. the mode filter 2 is arranged between the applicator 10 and the blocking filter 3.
- the inlet opening 11 has a rectangular cross-sectional area with a height H1 of approximately 55 mm and a width B1 of approximately 550 mm.
- the mode filter 2 in the present case consists of a shaft made of metallically conductive material whose cross-sectional area substantially coincides with that of the inlet opening 11, thus also has a rectangular shape with the width B2 and the height H2, where B2 «B1 and H2 « H1.
- the length L2 of the mode filter 2 is approximately 660 mm in the illustrated embodiment.
- the barrier filter 3 is also made of a metallically conductive material and also has a rectangular cross-section. While the width B3 of the barrier filter 3 substantially coincides with the width B1 of the inlet opening 11 and thus the width B2 of the mode filter 2, the barrier filter 3 has a height H3 of approximately 106 mm. The length L3 of the blocking filter 3 is approximately 460 mm in the illustrated example.
- the blocking filter 3 has an opening 30 for the passage of the material 4, the dimension of which corresponds essentially to the width B1 and the height H1 of the inlet opening 11 of the applicator 10 or the width B2 and the height H2 of the mode filter 2.
- metallically conductive pins 5 are screwed.
- the pins 5 in this case each form a two-dimensional periodic structure 6 extending over the entire surface of the ceiling surface 3a or the bottom surface 3b in the form of a square grid with a mesh size M of 25.5 mm.
- the pins 5 have a cylindrical shape with a diameter of about 15 mm and a length of about 25.5 mm and are screwed in vertical alignment on the respective inner sides of the ceiling surface 3a and the bottom surface 3b, i. they rest with their circular base on the inner surfaces.
- the notch filter 3 is suitable for blocking the wave modes TE m0 in the vicinity of the operating frequency 2450 MHz.
- the mode filter 2 blocks the exit of those wave modes TE mn (n> 0) and TM mn which may possibly be propagated in the applicator 10 from the applicator 10, which can not be blocked by the blocking filter 3.
- the device 1 according to the invention can also be operated at other frequencies with appropriately adapted geometry, eg in one of the ISM bands at 434 MHz, 896 or 915 MHz or 5800 MHz.
- Decisive for the scaling of the dimensions is the ratio of the wavelengths corresponding to the frequencies to one another.
- an attenuation of the leakage radiation emerging from the applicator 10 can be achieved by more than 100 dB.
- the blocked in the notch filter 3 wave modes TE m0 are substantially not attenuated in the present embodiment in the filter block 2 upstream of the notch filter 3. Consequently, the length L3 of the mode filter 3 can be almost completely included in a determination of the design of the total effective length of the applicator 10 in view of the desired power input into the product 4, ie the required length of the applicator 10 in this sense can by the length L3 of the mode filter 3 can be reduced.
