Description

Die vorliegende Erfindung betrifft eine mobile Einrichtung zum Erwärmen einer Oberflächenschicht, mit einem fahrbaren Gehäuse und einer daran befestigten Heizvorrichtung.The present invention relates to a mobile device for heating a surface layer, with a mobile housing and a heating device attached thereto.

Aus der DE-OS 26 18 006 ist eine mobile Einrichtung der eingangs erwähnten Art bekannt, bei der im Gehäuse ein Brenner, z.B. ein Propanbrenner, ein Gebläse zum Drücken von Luft durch den Brenner und ein Luftausblasteil untergebracht sind, so dass erhitzte Luft mit relativ einfachen Mitteln über einen grossen Flächenbereich konzentriert werden kann. Für diese Einrichtung gibt es eine Vielzahl von Anwendungsfällen. So kann sie in der Bauindustrie zum Trocknen von Strassen vor dem Aufbringen von Asphalt oder im allgemeinen nach Regenfällen eingesetzt werden. Beim Strassenbau kann sie auch zur Behebung der Trockenfäule, die darin besteht, dass sich das im Strassenbelag befindliche Oel absetzt, wodurch die Oberfläche bröcklig und trocken wird, verwendet werden. Durch die Einrichtung beim Fahren auf einer Asphaltstrasse abgegebene Wärme zieht das Oel wieder in die Oberfläche der Strasse zurück, wodurch die Strasse in einen guten Zustand gebracht werden kann. Andere Anwendungsbereiche für die Einrichtung ergeben sich in Verbindung mit Sportanlagen, wo Spielfelder, Pferderennbahnen oder Automobilrennstrecken vor der nächsten Sportveranstaltung durch Vorbeifahren der Einrichtung getrocknet werden können.From DE-OS 26 18 006 a mobile device of the type mentioned is known, in which a burner, e.g. a propane burner, a blower for pushing air through the burner and an air blowing part are housed so that heated air can be concentrated over a large area with relatively simple means. There are a variety of use cases for this facility. For example, it can be used in the construction industry to dry roads before applying asphalt or in general after rainfall. In road construction, it can also be used to remedy the dry rot, which consists in the oil in the road surface settling, which makes the surface crumbly and dry. The heat emitted when driving on an asphalt road pulls the oil back into the surface of the road, which means that the road can be brought into good condition. Other areas of application for the facility arise in connection with sports facilities, where playing fields, horse racing tracks or automobile racing tracks can be dried by passing the facility before the next sporting event.

Nachteil dieser Anordnung ist, dass die an der zu erwärmenden Oberfläche vorbeiströmende heisse Luft ihre Wärme nur zu einem kleinen Teil dieser Oberfläche abgibt, die Restwärme wird in Form von Verlustwärme der Umgebung abgegeben. Der Energiebedarf dieser Einrichtung ist daher relativ hoch. Zur Durcherwärmung der gewünschten Oberflächenschicht braucht man daher relativ viel Zeit, die in Form von Arbeitszeit aufgebracht werden muss. Aus diesen Gründen ist die in der DE-OS 26 18 006 beschriebene Einrichtung wirtschaftlich nachteilig.The disadvantage of this arrangement is that the hot air flowing past the surface to be heated only gives off its heat to a small part of this surface; the residual heat is dissipated in the form of heat loss from the surroundings give. The energy requirement of this facility is therefore relatively high. It takes a relatively long time to warm up the desired surface layer, which must be spent in the form of working hours. For these reasons, the device described in DE-OS 26 18 006 is economically disadvantageous.

Aus der DE-OS 24 41 379 ist eine Aufreisservorrichtung für aus Asphalt bestehende Strassenbeläge bekannt, die eine Arbeitsstation einer Strassenerneuerungsmaschine bildet. Während die Strassenerneuerungsmaschine sich über einen alten Strassenbelag hinweg bewegt, wird am Vorderende der Maschine die Strassenoberfläche bis zu einer Tiefe von etwa 5 cm oder mehr aufgeheizt und in einem Mittelabschnitt der Maschine, wo sich die Aufreisservorrichtung befindet, der Strassenbelag aufgegraben. Der Menge des jetzt zerkleinerten alten Strassenbelages wird eine Menge neuen Asphalt-Materials zugesetzt, um einen Strassenbelag von ursprünglicher Höhe herzustellen. Die Menge des zugesetzten neuen Asphalt-Materials entspricht gerade der Materialmenge, die erforderlich ist, um Schlaglöcher und dergleichen, die im alten Strassenbelag vorhanden waren, zu füllen. Die Maschine hinterlässt eine erneuerte Strassenoberfläche. Nachteil dieser Anordnung ist, dass für die Aufheizung der Oberlächenschicht der Strasse ein mit Pentan betriebener Strahlungsheizbrenner vorgesehen ist, der zu Verkohlung der Oberfläche und dadurch zur Qualitätsverminderung der-erneuerten Strassenoberfläche führen kann. Anderseits wird auch bei dieser Heizanordnung ein grosser Teil der Wärme von der Strassenoberfläche reflektiert, wodurch der Wirkungsgrad der Heizung relativ schlecht ist und die Umwelt mit der Verlustwärme belastet wird. Die relativ hohe Verlustwärme wirkt auf Pflanzen und Gegenstände der Umgebung negativ aus. Die hintereinander angeordneten Heiz- und Aufreisservorrichtungen erfordern eine relativ lange und daher kostenaufwändige Maschine. Gesamthaft gesehen ist die in der DE-OS 24 41 379 beschriebene Strassenerneuerungsmaschine sowohl im Betrieb als auch bei der Herstellung wirtschaftlich nachteilig.From DE-OS 24 41 379 a ripping device for asphalt road surfaces is known, which forms a workstation of a road renewal machine. At the front end of the machine, as the road renewal machine moves over an old road surface, the road surface is heated to a depth of about 5 cm or more and the road surface is dug in a central portion of the machine where the ripper is located. A lot of new asphalt material is added to the amount of the now crushed old pavement to make a pavement of the original height. The amount of new asphalt material added corresponds exactly to the amount of material required to fill potholes and the like that were present in the old road surface. The machine leaves a renewed road surface. The disadvantage of this arrangement is that a radiant heating burner operated with pentane is provided for heating the surface layer of the street, which can lead to charring of the surface and thereby to a reduction in the quality of the renewed street surface. On the other hand, even with this heating arrangement, a large part of the heat is reflected from the street surface, so that the efficiency of the heating is relatively poor and the environment is burdened with the heat loss. The relatively high heat loss has a negative impact on plants and surrounding objects. The heating and tear openers arranged one behind the other directions require a relatively long and therefore expensive machine. Overall, the road renewal machine described in D E-OS 24 41 379 is economically disadvantageous both in operation and in manufacture.

Aufgabe der Erfindung ist es, eine mobile Einrichtung zum Erwärmen einer Oberflächenschicht zu schaffen, die sowohl im Betrieb, als auch bei der Herstellung wirtschaftlich vorteilhaft ist und die nachteiligen Umweltbelastungen vermeiden lässt.The object of the invention is to provide a mobile device for heating a surface layer which is economically advantageous both in operation and in manufacture and which can avoid the disadvantageous environmental impacts.

Die gestellte Aufgabe ist dadurch gelöst, dass die Heizvorrichtung aus mindestens einer für die Ausstrahlung elektromagnetischer Wellen hoher Frequenz vorgesehenen, an einem Hochfrequenzgenerator angeschlossenen Elektrode besteht, wobei die Hochfrequenz führende Heizvorrichtung einerseits durch das metallische Gehäuse und anderseits im zwischen den Gehäuserändern und der Oberflächenschicht vorhandenen Spalt durch eine elektrisch leitende, mit dem Gehäuse elektrisch verbundene, flexible Schutzvorrichtung abgeschirmt ist.The object is achieved in that the heating device consists of at least one electrode which is provided for the emission of high-frequency electromagnetic waves and is connected to a high-frequency generator, the high-frequency heating device on the one hand through the metallic housing and on the other hand in the gap existing between the housing edges and the surface layer is shielded by an electrically conductive, flexible protective device electrically connected to the housing.

Die Elektrode kann bezüglich der Oberflächenschicht abstand- und winkelverstellbar sein.The electrode can be adjustable in terms of distance and angle with respect to the surface layer.

Die elektrisch leitende, flexible Schutzvorrichtung besteht vorteilhafterweise aus einem Netzgeflecht.The electrically conductive, flexible protective device advantageously consists of a network braid.

Bei einer mit mehreren am Gehäuse befestigten, für das Eindringen in die Oberflächenschicht vorgesehenen Dornen ausgerüsteten mobilen Einrichtung können einige Dorne am Gehäuse elektrisch isoliert befestigt und am Hochfrequenzgenerator angeschlossen sein und als "heisse" Elektrode dienen und die übrigen Erdpotential aufweisen und mit dem Gehäuse in elektrischer Verbindung stehen.In the case of a mobile device equipped with a plurality of spikes attached to the housing and intended for penetration into the surface layer, some spikes can be attached to the housing in an electrically insulated manner and connected to the high-frequency generator and serve as a "hot" electrode and have the remaining earth potential and with the housing in electrical form Connect.

In einer bevorzugten Einrichtung kann mindestens eine in der zur Oberflächenschicht parallelen Ebene gegenüber dem Gehäuse verstellbare Flachelektrode vorgesehen sein.In a preferred device, at least one flat electrode that is adjustable relative to the housing in the plane parallel to the surface layer can be provided be.

Innerhalb des Gehäuses kann mindestens ein auf die Oberflächenschicht gerichteter für die hochfrequente Strahlung vorgesehener Reflektor eingebaut sein.At least one reflector which is directed towards the surface layer and is intended for the high-frequency radiation can be installed in the housing.

An sich ist bekannt, dass mit Hilfe von induktiver, kapazitiver (dielektrischer) Erwärmung oder Mikrowellen-Erwärmung durch Erzeugung von hochfrequenten Wechselfeldern aus elektromagnetischen Wellen isolierende oder leitende Materialien mit einer bestimmten Dielektrizitätskonstanten, einem bestimmten Verlustfaktor bzw. einer bestimmten Permeabilität wegen der in ihnen auftretenden Verlustwärme je nach Frequenz und Grösse der elektrischen bzw. magnetischen Feldstärke erwärmt werden können. So zum Beispiel ist auch aus der CH-PS 584 391 eine Vorrichtung zum Trocknen von nassen, körnigen und/oder stückigen Gütern mittels Mikrowellen bekannt. Diese Vorrichtung, wie auch die anderen bekannten Vorrichtungen sind aber ortsfest. Die Fachwelt hat gegen die Anwendung mobiler Einrichtungen mit Hochfrequenzerwärmung bisher Vorurteile gehabt, denn Mikrowellen Störungen von Radiowellen und nachteilige Wirkungen auf den menschlichen Körper bewirken können. In ortsfesten Vorrichtungen hat man diese Probleme bereits gelöst. Die vorliegende Erfindung zeigt eine für fahrbare Vorrichtungen anwendbare Lösung, indem die Hochfrequenz führenden Teile einerseits durch das metallene Gehäuse und anderseits durch die im zwischen den Gehäuserändern und der zu erwärmenden Oberflächenschicht vorhandenen Spalt angebrachte, elektrisch leitende, flexible Schutzvorrichtung gegen das Austreten von Mikrowellen abgeschirmt sind.It is known per se that with the help of inductive, capacitive (dielectric) heating or microwave heating by generating high-frequency alternating fields from electromagnetic waves, insulating or conductive materials with a certain dielectric constant, a certain loss factor or a certain permeability because of the occurring in them Heat loss can be heated depending on the frequency and size of the electrical or magnetic field strength. For example, a device for drying wet, granular and / or lumpy goods by means of microwaves is also known from CH-PS 584 391. However, this device, like the other known devices, is stationary. The professional world has had prejudices against the use of mobile devices with high-frequency heating, since microwaves can cause radio wave interference and have adverse effects on the human body. These problems have already been solved in stationary devices. The present invention shows a solution which can be used for mobile devices, in that the high-frequency parts are shielded on the one hand by the metal housing and, on the other hand, by the electrically conductive, flexible protective device provided in the gap between the edges of the housing and the surface layer to be heated against the escape of microwaves .

Im folgenden wird die Erfindung anhand von zwei Ausführungsbeispielen näher beschrieben. Es zeigen:

  • Fig. 1 eine mobile Einrichtung mit für das Eindringen in die Oberflächenschicht vorgesehenen Dornen, und
  • Fig. 2 eine mobile Einrichtung mit einer Flachelektrode. Das in Fig. 1 dargestellte mobile Bearbeitungsaggregat für Bauflächen-Hochfrequenz-Erwärmung im HF-oder Mikrowellen-Frequenzbereich 2,4 MIlz ist als Anhängerfahrzeug ausgebildet. Diese mobile Baugrund-Bearbeitungsanlage arbeitet als Aufreissvorrichtung mit einer verschiedenen Anzahl von Stahl- bzw. Aufreissern 1 bzw. 2 (Rippern) geeigneten Materials genügender mechanischer Festigkeit für den betreffenden Baugrund. Die verschleissfesten Aufreissdorne, deren Gestaltungsform dem jeweiligen Verwendungszweck zum Aufreissen, Bodenlockern, Strukturieren, Abtrocknen nassen Materials oder Beseitigen von Fremdeinschlüssen in den Teer- bzw. Bitumendecken oder im Erdreich angepasst werden kann, können über Einstellvorrichtungen 3 verschieden tief und unter verschiedenen Winkeln geometrisch in den Baugrund 4 abgesenkt werden. Die Dorne 1 bilden die "heisse" Elektrode des abstrahlenden HF-Sendeaggregates bzw. Mikrowellen-Senders 5. Die mit 2 bezeichneten Dorne sind von den mit 1 bezeichneten Dornen durch die Isolieranordnungen 6 getrennt. Die Elektroden 2 liegen auf geerdetem Potential. Zwischen den Dorn-Elektroden bilden sich aufgrund dieser geometrischen Kondensator-Konstellation elektromagnetische Felder aus, die in bekannter Weise die dazwischen liegende Materie als Dielektrikum mehr oder weniger stark erwärmen. Dabei lassen sich mehrere Aufreisser-Dorne so anordnen, dass elektrische Parallel- oder Reihenschaltungen oder ein Gemisch aus beiden entstehen. Durch geeignete, nicht dargestellte Reflektorvorrichtungen lässt sich die hochfrequente Energie mit Regeleinrichtungen zur Behandlung der Oberflächenschicht des Baugrundes 4 bzw. der zu bestrahlenden Bauflächen optimal einstellen.
The invention is described in more detail below with reference to two exemplary embodiments. Show it:
  • Fig. 1 is a mobile device with thorns intended for penetration into the surface layer, and
  • Fig. 2 shows a mobile device with a flat electrode. The mobile machining shown in Fig. 1 Unit for building surface high-frequency heating in the HF or microwave frequency range 2.4 MIlz is designed as a trailer vehicle. This mobile soil processing system works as a ripping device with a different number of steel or ripper 1 or 2 (rippers) of suitable material of sufficient mechanical strength for the relevant soil. The wear-resistant tear-open mandrels, the design of which can be adapted to the respective intended use for tearing open, loosening the soil, structuring, drying wet material or removing foreign inclusions in the tar or bitumen ceilings or in the ground, can be adjusted in different depths and at different angles using the adjusting devices 3 Soil 4 are lowered. The mandrels 1 form the "hot" electrode of the radiating RF transmitter or microwave transmitter 5. The mandrels 2 are separated from the mandrels 1 by the insulating arrangements 6. The electrodes 2 are at grounded potential. Due to this geometrical capacitor constellation, electromagnetic fields form between the mandrel electrodes, which in a known manner heat the material in between more or less strongly as a dielectric. Several ripper mandrels can be arranged so that electrical parallel or series connections or a mixture of both are created. By means of suitable reflector devices (not shown), the high-frequency energy can be optimally adjusted with control devices for treating the surface layer of the building ground 4 or the building surfaces to be irradiated.

Die Hochfrequenz- bzw. Mikrowellenquelle wird über eine Ankoppelvorrichtung, dem Hochfrequenz-Oszillatorteil und einem Hochspannungsgleichrichter mit einem elektrischen Kabel 7 versorgt. Die elektrische Energie zur Speisung der gesamten Anlage kann aus einem beliebigen Stromerzeugungsaggregat auf dem Fahrzeug oder über ein Drehstrom-Schleppkabel direkt aus dem elektrischen Netz bezogen werden. Zur Abschirmung der hochfrequenten Felder sind am Fahrzeuggehäuse 8 verschiedene flexible, elektrisch leitende Netzgeflechte oder ähnliche Schutzvorrichtungen 9 und 10 angebracht, um das Austreten von schädlicher Hochfrequenzenergie zu vermeiden.The high-frequency or microwave source is supplied with an electrical cable 7 via a coupling device, the high-frequency oscillator part and a high-voltage rectifier. The electrical energy for feeding the entire system can be obtained from any generator set on the vehicle or via a three-phase trailing cable directly from the electrical network. In order to shield the high-frequency fields, various flexible, electrically conductive meshes or similar protective devices 9 and 10 are attached to the vehicle housing 8 in order to prevent harmful high-frequency energy from escaping.

Das mobile Baubearbeitungsaggregat kann starr an das Zug- oder Schubfahrzeug angekuppelt werden, oder als ein-, zwei- oder mehrachsiger Anhänger mit Drehgestell auf den Rädern (im Beispiel Fig. 1 Räder 11 und 12) vom Mutterfahrzeug gezogen oder geschoben werden.The mobile construction processing unit can be rigidly coupled to the towing or pushing vehicle, or can be pulled or pushed as a single-, two- or multi-axle trailer with a bogie on the wheels (in the example Fig. 1 wheels 11 and 12) from the mother vehicle.

Eine weitere Ausführungsform eines mobilen Baubearbeitungsfahrzeuges zur Erwärmung der Oberflächenschicht des Baugrundes 4 bzw. von Bauflächen mit hochfrequenter Energie zeigt Fig. 2. Dieses ein-, zwei- oder mehrachsige Fahrzeug kann mit Muskel- oder Motorkraft gezogen oder geschoben werden. Es arbeitet ebenfalls mit einer Kondensatoranordnung 13 als Elektrode zur Auskoppelung der hochfrequenten Feldenergie. Die aktive Kondensatorplatte 13 ist in der Höhe und den Seitenlagen 14 mit einem Stellmechanismus 15 verstellbar. Bei Verwendung von Mikrowellenenergie ist eine Gegenelektrode nicht notwendig; jedoch lassen sich durch Anordnung geeigneter, in Fig. 2 nicht näher dargestellter Gegenelektroden oder Reflektoren auch Hochfrequenzanordnungen verwenden, bei denen das Hochfrequenzfeld die zu bearbeitende Materie als Dielektrikum zwischen zwei oder mehreren Elektroden erwärmt. Gemäss Fig. 2 wird die hochfrequente Energie über ein isoliertes Hochfrequenzkabel aus dem Hochfrequenz-Senderteil mit Koppeleinrichtung 16 angeschlossen. Zur Speisung des Hochfrequenzsenders dient der Hochspannungs-Gleichrichter 17 der seinerseits beispielsweise über ein Drehstrom-Schleppkabel 18 mit Elektroenergie versorgt wird. Das auf den Rädern 19 fahrbare Gehäuse 20 kann bedienungstechnisch mit den Steuereinrichtungen 21 zur Einstellung der Bestrahlungstiefe, des Temperaturniveaus der zu bearbeitenden Materie, der Fahrzeuggeschwindigkeit, usw. bedient werden. Zur Abschirmung hochfrequenter Strahlung wird das metallische Abschirmnetz 22 oder eine ähnliche Schutzvorrichtung vorgesehen.A further embodiment of a mobile construction processing vehicle for heating the surface layer of the building ground 4 or of construction areas with high-frequency energy is shown in FIG. 2. This one, two or more axles vehicle can be pulled or pushed with muscle or motor power. It also works with a capacitor arrangement 13 as an electrode for decoupling the high-frequency field energy. The active capacitor plate 13 is adjustable in height and the side layers 14 with an adjusting mechanism 15. A counter electrode is not necessary when using microwave energy; However, by arranging suitable counter electrodes or reflectors (not shown in FIG. 2), high-frequency arrangements can also be used in which the high-frequency field heats the material to be processed as a dielectric between two or more electrodes. 2, the high-frequency energy is connected via an insulated high-frequency cable from the high-frequency transmitter part with coupling device 16. The high-voltage rectifier 17 is used to supply the high-frequency transmitter, which in turn is supplied with electrical energy, for example, via a three-phase trailing cable 18. The housing 20, which can be moved on the wheels 19, can be operated in terms of operation with the control devices 21 for setting the irradiation depth, the temperature level of the material to be processed, the vehicle speed, etc. The metallic shielding network 22 or a similar protective device is provided for shielding high-frequency radiation.

Die beschriebene mobile Einrichtung eignet sich zur flächenhaften Erwärmung von dielektrischen Oberflächen als zu bestrahlende Flächen, vorwiegend als Untergrund, aber auch als darüber liegende oder seitlich befindliche Oberflächen mittels elektromagnetischer Feldenergie im Hochfrequenz- oder Mikrowellenbereich. Durch den Aufbau der im Baufahrzeug befindlichen Sendeanlage wird vom Arbeitskondensator des Senders oder mit Hilfe von metallischen Reflektoren elektromagnetische Wellenstrahlung auf die zu erwärmende Oberfläche aufgebracht. Diese hochfrequente Strahlung kann mehr oder weniger stark durch eine auf dem Fahrzeugbefindliche Regeleinrichtung dosiert werden, so dass die zu behandelnde Oberfläche berührungslos und homogen oder inhomogen, je nach den dielektrischen Eigenschaften des Mediums, aus kleiner oder grösserer Distanz angestrahlt bzw. durchstrahlt werden kann. Demzufolge lassen sich aus kleiner oder grösserer Distanz verschiedene Bauflächen vertikal, horizontal oder unter beliebigen Anstellwinkeln behandeln, wobei sich beispielsweise als Bauflächen Strassendecken, Mauerwände, Gips-, Kunststoff, Holzwände, usw. dielektrisch oder auch induktiv erwärmen lassen.The mobile device described is suitable for the areal heating of dielectric surfaces as surfaces to be irradiated, predominantly as a base, but also as surfaces lying above or to the side by means of electromagnetic field energy in the high-frequency or microwave range. Due to the structure of the transmitter in the construction vehicle, electromagnetic wave radiation is applied to the surface to be heated by the working capacitor of the transmitter or with the help of metallic reflectors. This high-frequency radiation can be metered to a greater or lesser extent by a control device located on the vehicle, so that the surface to be treated can be irradiated or irradiated from a small or greater distance depending on the dielectric properties of the medium, in a contactless and homogeneous manner. As a result, different building surfaces can be treated vertically, horizontally or at any angle from a small or larger distance, with road surfaces, wall walls, plaster, plastic, wooden walls, etc. being able to be heated dielectrically or inductively, for example.

Es eröffnen sich darüber hinaus zahlreiche neue Perspektiven zur erwärmungstechnischen Behandlung, zur chemischen und zur mechanischphysikalischen Umstrukturierung der Baugrundflächen, die erst mit der Behandlung durch Hochfrequenz-Erwärmung möglich werden.In addition, numerous new perspectives open up for thermal treatment, for chemical and mechanical-physical restructuring of the building ground areas, which are only possible with the treatment by high-frequency heating.
