Definitions
- the invention relates to a device for microwave exposure to materials and piece goods, with the following features: a) an in particular multimodal microwave chamber is provided which has at least one loading passage with a closing device; b) at least a part of the microwave chamber and the closing device are mounted such that they can move relative to one another, and an actuating device, preferably driven by a motor, is provided for switching between the closed position and the open position.
- Devices of this type are generally known as prior art and are used for a wide variety of industrial applications, including for purposes of heating, in particular drying, e.g. of molds and cores in foundry technology, but also for the triggering and control of reactive processes such as the hardening of plastics and the like.
- Essential for industrial use is the space requirement not only of the microwave systems themselves, especially the microwave chambers, but also of associated loading equipment. With regard to the rational flow of continuous processes, the structural adjustment of the chambers with their feed passages to different circumstances of the process and the treatment goods as well as the operational environment is particularly important in this context.
- the combination of features essential to the invention comprises the arrangement of at least one loading passage in the region of a bottom section of the microwave chamber. This allows an often optimal adaptation of the microwave system for low-guided items to be treated, in particular those moving directly on the floor of the building, and corresponding sports systems, especially in the case of heavy or bulky piece goods. An arrangement of the chamber above the loading area then also offers the advantage of a space-saving construction with a small footprint.
- the solution variant according to claim 2 with at least one loading passage in the area of a ceiling section of the microwave chamber comes into consideration, inter alia, advantageously in connection with highly guided transport systems, especially, for example, for hanging objects to be transported as well as for bulk materials supplied via high-level container outlets or channels.
- the loading area can be arranged above the chamber, which in turn results in a space-saving construction with a small footprint.
- the closing device being designed to be movable between the closed position and the open position
- the solution variant according to claim 3 - taking into account the circumstances of the application - enables the following advantages:
- a single loading passage is sufficient for a change of goods without reversing the direction, namely that the movable chamber or a suitably designed chamber part with corresponding wall sections completely releases the treatment position of the goods and the feed and discharge paths in the open position.
- the movable chamber part is moved over the goods and engages around them with its wall sections, which finally make a microwave-tight connection with the closing device. Furthermore, this results in the possibility of transferring the items to be treated - in particular voluminous items to be treated or, for example, containers with items to be treated therein - straight to the treatment position with the chamber in the open position, that is to say out of the transport path of the item, and without lifting and lowering processes, and continue to demand.
- Such a construction can optionally be carried out in combination with the features of the solution variants according to claim 1 or 2, which also results in the combinatorial advantages specified there and further.
- it can be useful in certain application conditions to design the closing device and the microwave chamber to be movable in order to switch between the closed state and the open state. Corresponding advantages can essentially be achieved.
- the microwave chamber comprises a stationary first part which is arranged at a distance from a closure element which is also stationary.
- This stationary first chamber part preferably contains the microwave feed or a substantial part of it, in particular at least one magnetron and / or waveguide with associated adaptation and, if necessary, tuning elements of a known type.
- the chamber also comprises a movable second part, which is part of the termination device is designed to be movable between the closed position and the open position. This in turn enables an advantageous construction with only one loading passage, which is formed by the distance between the stationary closure element and the likewise stationary first chamber part.
- the microwave feed or its essential components can now be arranged in a stationary manner in connection with the first chamber part.
- the microwave feed can be accommodated there if necessary.
- a movable termination device in the above sense, but above all also a stationary termination device and possibly even in combination with a microwave feed or parts thereof, it is possible in a further development of the invention to design one or more closure elements as supports or receptacles for items to be treated.
- closure elements are often essentially only two-dimensional, mostly plate-like structures, which, in contrast to the chamber, can be kept free of larger angled side parts and therefore have a simple construction for the desired closely adjacent arrangement of to and laxative means of transport are accessible.
- closure elements participating in the opening and closing movement these can even take over components of the transport movement and, for example, convey the treatment material lying on top into and out of the chamber.
- a development of the invention provides that at least one closure element is guided in its at least approximately horizontal position within its movement path between the closed position and the open position. This makes it easy to secure the goods in position.
- closure elements can furthermore be provided with holding means and / or transport means, in particular at least one roller conveyor, for the material to be treated.
- Such closure elements then represent a component of the transport system and enable a continuous transport path to be designed in a structurally relatively simple manner.
- the holder or transport means can then be arranged with substantial advantages with regard to robustness and operational safety in the area of a surface of the closure element which is in the microwave state when in operation and can be designed to be retractable into the microwave chamber, in particular microwave-proof or sealed against microwave access and / or microwave exit.
- Fig.l a first example of an inventive
- Microwave system with a fixedly arranged microwave chamber provided in the bottom area with a loading passage and a passage transport system located underneath in a partial vertical section with a sectional plane parallel to the direction of transport;
- FIG. 2 shows a second example of a microwave system according to the invention with a microwave chamber movably arranged between the closed and open positions, otherwise constructed similarly to the embodiment according to FIG. 1 and in the same manner of illustration;
- FIG. 3 shows a third example of a microwave system according to the invention with a microwave chamber which is again arranged in a fixed manner but is provided in the ceiling area with a feed passage and a corresponding overhead transport system, representation as above;
- Microwave system with a microwave chamber again provided in the ceiling area with a feed passage and a corresponding continuous transport system, but with a fixed and a movable chamber part between the closed and open positions, also shown as above; 5 shows the cross section of a microwave seal between the movable chamber part and a closure element for the exemplary embodiment according to FIG. 4;
- FIG. 6 also shows the cross section of a microwave seal between the movable and the fixed chamber part for the exemplary embodiment according to FIG.
- the microwave system comprises a multimodal microwave chamber MK1.
- the characteristic of this known chamber type is a so-called "wild" microwave field generated by multiple reflections with mode and frequency splitting as well as a chaotic, at best quasi-steady-state and not too strongly non-uniform energy distribution when idling, it is characterized by constructive simplicity and is widely used.
- the chamber MK1 is provided in a conventional manner with a microwave supply MS, which has a larger number of magnetrons 14 arranged on the chamber wall.
- a microwave supply MS which has a larger number of magnetrons 14 arranged on the chamber wall.
- the antennas 15 of the magnetrons are arranged so as to intervene directly in the interior of the chamber without an intermediate waveguide, which is basically sufficient for multimodal operation.
- a suction 10 ensures the removal of vapors and gases that arise during the treatment.
- a feed passage BDL1 is formed within the bottom portion BA of the chamber and extends in a horizontal plane.
- the chamber MK1 is arranged on a frame 17 in an elevated position above a transport system TRS for the items to be treated BG which are run in cyclical operation.
- a microwave-permeable container is indicated with a material, not shown, to be acted upon by the microwaves.
- the transport system is divided into successive stations 11, 12, 13 which have means of transport TRM in the form of roller conveyors with associated drive means ATR. For the sake of clarity, the latter are only indicated at the middle station 12.
- the means of transport of the stations are designed in such a way that the containers with the material to be treated can easily overcome the distances between the successive roller conveyors.
- the station 12 is located vertically below the feed passage BDL1 of the microwave chamber and comprises a closure device AV with a plate-like closure element VE1, which also extends in a horizontal plane and whose outer edge 16 extends over the inner edge of the passage BDL1 in a vertical projection by a predetermined amount .
- the closure element VE1 also forms a support element for the means of transport TRM of the station 12 and is connected to an adjusting device STE arranged underneath, by means of which the closure element VE1 is raised in the sense of the double arrow P1 from the shown open position while the material to be treated BG is moved into the chamber into a closed position and can be lowered again after the treatment.
- a microwave seal MD for example, which is conventional per se and which is arranged on the underside of the edge area of the feed passage BDL1 and surrounds it without gaps in a horizontal plane.
- the material to be treated is passed in successive feed and standstill cycles, the material to be treated or a corresponding container or a defined delimited load of material to be treated in the standstill cycles being aligned vertically in alignment with the feed passage by means of conventional position sensors and control means (not shown). It is evident from the above explanation that it is essential to the invention that at least one closure element is designed as a support or receptacle for items to be treated, which is an advantageous simplification in some applications.
- holding means for example clamps or securing stops
- the holding or transport means are arranged in the area of a surface of the closure element on the microwave side in the operating state and can be moved with it into the microwave chamber, in particular microwave-proof or sealed against microwave entry and / or microwave exit, preferably in the area of shaft passages or bearings .
- a construction has proven itself here in which a closure element has a microwave sealing region which extends along an outer contour of the closure element and which, in the closed state, is assigned to a corresponding microwave sealing region of the microwave chamber.
- the receiving, supporting, holding or transporting means for the material to be treated are arranged on a microwave-side surface section and within the microwave sealing area of the closure element.
- the closure element For the operational safety of the device, it is important to guide the closure element in an at least approximately horizontal position within its path of movement between the closed position and the open position. This facilitates the securing of the position and enables higher adjustment speeds. It is also essential that the edge contour at least of a section of the loading passage runs essentially in one plane and the relative movement P2 of the closure element is directed at least in a section of the movement path adjacent to the closed position, in particular at an approximately right angle, to the plane of the edge contour of the loading passage.
- an at least sectionally curved course can also be considered, which can be implemented particularly advantageously with the aid of a multi-link gearbox and / or a slideway or runway gearbox.
- a plurality of loading passages and closure devices or closure elements can optionally be provided on a microwave chamber. It is also within the scope of the solutions according to the invention that microwave supply or parts thereof, e.g. Provide magnetrons and / or associated waveguides, tuning and adaptation means on a stationary termination device. This can be particularly advantageous in the case of a stationary termination device.
- a microwave chamber MK2 with a microwave feed MS and a feed passage BDL2 arranged inside the bottom section BA of the chamber is again provided.
- a termination device AV2 with a plate-like closure element VE2 which, like the feed passage BDL2, is arranged in a horizontal plane and whose outer edge, as in the embodiment according to FIG. 1, engages the inner edge of the feed passage in a vertical projection by a predetermined amount.
- the closing device AV2 is arranged essentially stationary and the microwave chamber MK2 is designed to be movable in order to switch between the closed state and the open state.
- the raised open position is indicated in FIG.
- an adjusting device STE with vertical hydraulic cylinders is provided, which, according to double arrows P1, provides for the lifting of the microwave chamber into the indicated open position and, according to arrows P2, for the lowering into the closed position.
- the middle station 22 comprises a stationary, plate-like closure element VE2, which is at the same time a carrier for the means of transport.
- the station 12 is again vertically below the charging passage of the microwave chamber, so that a microwave seal MD surrounding the passage comes into operative connection with the overlapping edge region of the closure element VE2 when the chamber is lowered according to arrows P2.
- this construction offers the advantage of a simpler and lower structure of the transport system.
- the movable arrangement of the microwave chamber requires a certain amount of effort, namely essentially a height-variable connection of the suction 20 - indicated here, for example, as a bellows - and movable electrical connecting lines 25 for the microwave supply.
- the application decides on the weighting of the respective advantages.
- the embodiment according to FIG. 3 presents itself as a spatially vertical inversion of that according to FIG. 1, in that there is also a fixed microwave chamber MK3 at the bottom with a loading passage BDL3 arranged in its ceiling section DA and an overhead transport system TRS attached to a support frame 37 successive stations 31, 32, 33 is provided.
- the transport system corresponds essentially to the embodiment according to Fig.l, but with hanging roller conveyors arranged as a means of transport TRM.
- the treatment items BG for example each consisting of a group of workpieces or the like, is suspended from a support plate 36 which lies on rows of rollers arranged transversely to the plane of the drawing with a mutual horizontal spacing and is transported in time by a roller drive.
- the middle station 32 again forms a closing device AV3 with a plate-like closing element VE3, which can be moved vertically between the open position shown and a lowered closed position by means of an adjusting device STE according to double arrow P1.
- the outer edge of the closure element VE3 overlaps the inner edge of the feed passage BDL3 of the microwave chamber in a vertical projection by a predetermined amount.
- the underside of the outer edge area of the closure element VE3 comes into operative connection with a microwave seal MD on the inner edge of the loading passage BDL3.
- both the termination device AV3 and the microwave chamber MK3 are vertically adjustable, specifically each in opposite directions to each other between the closed and open position. This is shown schematically in FIG. 3, but is readily understandable, only illustrated by a double arrow P3 assigned to the microwave chamber.
- the microwave chamber MK4 comprises a fixed lower chamber part KTI and a component of a closing device AV4 designed as a closure element VE4.
- the chamber part KTI and the closure element VE4 are mutually Arranged vertically and thus form a loading passage BDL4 freely accessible along the entire chamber circumference.
- An overhead transport system TRS with successive stations 41, 42, 43 is fastened to a support frame 47 and largely corresponds to the embodiment according to FIG. 3, but the middle station 42 is designed to be stationary at the same height as the other two stations.
- the station 42 with its closure element VE4 designed as a horizontal support plate is part of the termination device AV4, namely together with a second part KT2 of the microwave chamber, which can be moved vertically between an upper closed position and a lower open position by means of a hydraulic adjusting device STE similar to FIG .
- the second chamber part KT2 is designed as a casing body that slidably encompasses the first chamber part KTI.
- the chamber part KT2 is indicated in its upper closed position S, in the half representation on the right of this center line in its lower open position 0.
- a microwave seal MD1 is provided on the upper edge of the second chamber part, which comes into contact with the closure element VE4 in the closed position, while at the lower end of the second chamber part there is a microwave seal MD2 encompassing the first chamber part, which at least when the closed position is reached takes effect.
- a microwave supply MS is accommodated in the first stationary chamber part, but it can, if necessary, also be partially provided in the area of other wall sections.
- suction 40 leads through the plate-shaped closure element VE4. 5 shows the cross section of the microwave seal MD1 on a larger scale.
- a contact seal KD is additionally provided as close as possible to point A.
- FIG. 6 shows, on the same scale as FIG. 5, a reactive barrier filter with ribs or pegs RZ and transverse recesses QA that follow one another in the exit direction of the microwaves through the gap SP between the first and second chamber parts.
- blocking filters are known in principle e.g. from JOURNAL OF MICROWAVE POWER, 8 (1), 1973, pages 101 to 110.
- a contact seal KD is provided, which in the course of the closing movement of the second chamber part in order to reduce wear and tear only when one is overcome slightly outwards, i.e. in the direction of decreasing width of the gap SP inclined portion AS of the wall of the first chamber part is effective.
