    Device for cleaning a filter or catalyst
    The invention relates to a device for cleaning an article such as a filter or catalyst, which can be traversed by a gas, in particular a particle filter or catalyst used in an exhaust tract of a motor vehicle, comprising a closable housing, a disposed within the housing base, on which or with which is the object can be positioned, and at least one disposed within the housing cleaning means with which in the article adsorbed solids and / or liquids are removable.
    In many vehicles, filters and / or catalysts for purifying exhaust gases are provided today in an exhaust tract. These include in particular particulate filters with which soot particles are filtered out of an exhaust gas of a diesel-powered motor vehicle. Such particle filters can be actively or passively regenerated during operation. Nevertheless, it is at regular intervals, z. B. after a performance of 50,000 km, required, especially for trucks or construction vehicles to expand the Partikelfiiter and regenerate as completely as possible in a suitable device. The same applies to catalysts which are used for example in exhaust fumes for the selective catalytic reduction of nitrogen oxides. These catalysts, like Partikelfiiter by a gas such as an exhaust gas flow through, however, lock in a motor vehicle over time due to loading with ash or, for example, in diesel-powered vehicles, soot particles.
    Currently known devices for cleaning filters and / or catalysts that are used in an exhaust tract of a motor vehicle, have the disadvantage that only a moderate and therefore unsatisfactory cleaning effect is achieved. In addition, with known devices, no statement can be made regarding a quality of a filter and / or catalyst that has been in use for a longer period of time. Also, a cleaning success can not be verified.
    The object of the invention is to stabilize a device of the type mentioned, in which the disadvantages of the prior art are avoided or at least reduced. 2 · »« · · «· ·«
    This object is achieved according to the invention if, in a device of the type mentioned at the beginning, at least one balance for detecting a weight of the object and / or at least one device for detecting defects such as cracks and / or holes in the article is provided inside the housing and / or one Cleaning device above and a cleaning device is arranged below the base to clean the object from two sides.
    An advantage achieved with a device according to the invention can be seen in particular in that a weight of a filter or catalyst to be cleaned can be detected by a balance before a start of a cleaning process, and a weight loss caused by the cleaning can be traced during the cleaning process. If no further weight loss occurs within a given period of time while continuously pursuing a weight loss, the cleaning process can be ended. By at least one device for detecting defects such as cracks and / or holes in the article can be determined in an advantageous manner, whether the cleaned object is still fully functional or optionally, despite cleaning, must be replaced because there are too many defects. For example, it is possible for filters to have larger cracks or holes, so that a bypass is formed for the soot particles to be filtered out in the filter itself and a cleaning effect of the filter is no longer present to the required extent. In this case, the filter is no longer useful for further use despite cleaning. If both a scale for determining the weight of the object as well as a (test) device for detecting defects of the object is provided, for. As cracks, holes or blockages, on the one hand a complete cleaning and on the other hand, a functionality of the object can be ensured with a single device or in a single process. An arrangement of cleaning devices above and below the base of the object to be cleaned, for example, applied from two sides with compressed air and thus cleaned very efficiently.
    It is advantageous if the housing has a base on which an upper housing part is fixed, wherein the base is arranged in the upper Gehäuseteii. This allows both a good handling in the introduction of the object to be cleaned in the device as well as a compact design. The base can be designed for example with a height of 70 to 100 cm. The object can then be arranged on the base without stooping. In the base, in turn, individual components may be arranged whose function is required in a cleaning of the object. Thus, a given space is used optimally. In this context, the upper housing part preferably has a vertically displaceable or openable jacket, so that the base is accessible. In principle, it is sufficient that the jacket can be opened in order to be able to introduce the article into the device for cleaning. However, it is particularly advantageous if the jacket as a whole is vertically displaceable. The base is then accessible from all sides, which is favorable in terms of easy insertion of the article into the device. It is particularly preferred that the base is formed with a smaller cross-section than the shell and the jacket over the base is displaced downwards. Although it is also possible that the jacket can be moved upwards, which, however, in the extended or pushed up state of the jacket brings a greater height of the device with it is the jacket down on the base displaced, is a good accessibility given the base, without the height of the device would change when moving the shell.
    No special requirements are placed on the design of the jacket per se, but the jacket is expediently designed to be transparent, so that a cleaning process can be observed and, if the complications are found, the cleaning process can be stopped manually. For a transparent design of the shell of this is suitably made of a plastic such as a Poiycarbonat, for a tight closure upwards, the upper housing part on a head-side cover plate which is rigidly connected to the base and forms a sealing stop for the jacket. The rigid connection or possibly rigid connections between the cover plate and the base are expediently at the same time as guides for the Mantei when moving or as guide rails.
    The base can be designed in any desired way, as long as it is suitable for receiving the object to be cleaned. Preferably, the base, for a simple embodiment, comprises a horizontal support surface for positioning the object. The object to be cleaned is then merely to be placed on the support surface. In addition, it can be provided that one or more fastening means are provided laterally of the support surface for fixing the object. This can be avoided that the object moves during a cleaning with compressed air. The intended support surface may be partially light and gas permeable.
    A Gasdurchiässigkeit is appropriate so that the object to be cleaned in the region of an upper end, for example, can be acted upon with compressed air and the passing through the object compressed air escape at a lower end of the article and can pass through the support surface, whereupon the compressed air blown through the object removed solids and / or liquids into the base, from which the compressed air, if necessary, after cleaning, is discharged. For this purpose, the support surface is expediently designed as a grid. The support surface can also act as a balance, if the support surface is mounted on corresponding sensors. A design of the support surface in transparent form, in particular as a grid, proves to be particularly useful if below the support surface at least one light source for irradiating a lower end of the article is provided and in the housing above the support surface at least one mirror is arranged, with which an upper End of the article upon irradiation of the lower end of the article outside the housing is observable. With appropriate irradiation of an object can then be observed outside of the housing, whether in the region of the upper end of the object light emerges or an irregular light intensity is given. This makes it possible to conclude on the cracks and / or holes or general operational wear. If the jacket is transparent, no special measures are required in order to be able to carry out a corresponding observation outside the housing or the device. If, on the other hand, the sheath is not transparent, at least a small viewing window is present in the sheath so that the corresponding observation or examination can take place. Alternatively, it can also be provided that at least one light source for irradiating a lower end of the article is provided beneath the support surface and at least one camera or a light-sensitive sensor is arranged in the housing above the support surface, with which or with which an image of the upper end of the Object can be received upon irradiation of the lower end of the article and outside of the housing on a display can be displayed. The at least one light source is preferably rotatably and / or pivotably mounted in both alternatives, so that it is possible for the light source to be rotated. It may be in a parked position during a cleaning process, but may be in an active position for irradiation of the lower end of the cleaned one upon completion of the cleaning process. *** "" Ψ Ψ Ψ «« «· · · · · · · · · · · · · · aktive aktive aktive aktive aktive aktive Objectes can be brought. This ensures that the at least one light source is neither contaminated nor located during a cleaning process in a flow direction of the compressed air. For cleaning, the cleaning device advantageously has one or more compressed air nozzles arranged above and / or below the base, which are movably mounted in a plane above or below the base and are in communication with a compressed air reservoir for feeding the compressed air nozzles. The object to be cleaned can then be easily pressurized with compressed air to effectively remove adsorbed solids and / or liquids therein. To fully pressurize an entire head-side and / or bottom-side surface of an object to be cleaned or its upper and lower end with compressed air, the compressed-air nozzles are mounted directly or indirectly on a rotatable or pivotable axis, If the axis is rotatable, this can order Rotate 360 °, so that an object to be cleaned, which is usually present as a round filter or catalyst, head and / or bottom side can be fully pressurized with compressed air to achieve efficient cleaning. A pivotable design of the axis offers advantages in that the compressed air is supplied from the compressed air reservoir via hoses to the compressed-air nozzles, which makes a rotation of the axis technically complex. With a pivotable design, it is sufficient that a Schwenkwinkei is given by up to 180 °, although this angle can also be at least slightly greater. The axle then pivots back and forth between two end positions, so that likewise the object to be cleaned on the top side and / or bottom side can be fully pressurized with compressed air, without, however, being able to twist the compressed air supply lines. It is particularly preferred that the Druckiuftdüsen are mounted on the axle via pivotable hinge rods. This makes it possible to manage with a minimum of compressed air nozzles, since they are not only in the circle or back and forth movable, but can also be moved radially during a rotational or pivoting movement. In this context, it is particularly preferred that two joint rods are each provided with a compressed air nozzle, the Geienkstäbe are end mounted on the axis and preferably pneumatically actuated piston-cylinder units are provided, which are fixed to the axis and with the hinge rods in 6 * · «·« · · 6 * · «·« · ·
    «« ·
    Connection to pivot it, in this case can be covered with only two opposite ends of the axis above hinge pin attached Druckiuftdüsen an entire head-side or bottom-side surface of an object to be cleaned, when the compressed air nozzles during the pivoting movement simultaneously constant radially retracted and then extended again. The compressed air nozzles are expediently arranged at a free end of the joint rods. It then arise for a projected movement of the compressed air nozzles over an applied surface spiral tracks that extend from one edge of the surface to a center.
    It can also be provided that a labeling device for identifying the object is arranged within the housing. This makes it possible to purify the cleaned items, for example with a test seal, and to show them in a functional manner. In addition, especially if in addition a reader is provided within the housing, which may be combined with the label device, data of an object to be cleaned can be compared with already existing data. The already existing data can relate, for example, to a weight of the article in the original state, ie before a first use, or after a previous cleaning. It is then possible to detect a susceptible permanent increase in weight, which can not be remedied by a cleaning process, which in turn is important in terms of a functioning of the object.
    As mentioned, the object is usually cleaned with compressed air, which is sufficient for many cases. However, there may also be incidences that some of the adhering solids can be removed only by long cleaning processes or not at all when merely exposed to compressed air. For such cases, it may be expedient that at least one device, which can be arranged on the article, be provided in the housing for blowing a hot gas through the article. The instable device, which may be in the form of a bell for example, is then lit on the article and the article is charged with a hot gas, for example, to burn larger accumulations of soot particles in a pore system of a filter and thus an at least partially blocked pore system again expose. For testing and diagnostic purposes, additional means may be provided for injecting particles at an upper end of the article and a measuring device for measuring particles emerging at a lower end of the article. This makes it possible to test a cleaned article for particle adsorption. This is particularly useful for determining a functionality of soot particle filters.
    As already mentioned, components may be arranged in the base which are required for a cleaning process, in particular by means of compressed air. In particular, a filter and this subordinate a vacuum blower can be arranged in the base, so that the introduced into the housing for cleaning compressed air can be sucked and removed from the base. The upstream filter cleans the extracted air so that the solids and / or liquids blown out of a clean object are not released into the environment. Incidentally, a dust collecting container may also be provided on the bottom side, wherein the dust collecting container is arranged below the filter.
    The device as a whole is preferably cylindrical and advantageously has a height of about 100 to 180 cm.

    In Fig. 1 to 5, a device 1 according to the invention is exemplified. The device 1 is designed as a system for cleaning and for the diagnosis of filters and catalysts that are used in motor vehicles, especially trucks or construction vehicles, and are installed in these in the exhaust system. However, the device 1 can be used quite generally for the purpose of cleaning and diagnosing the condition of filter elements through which a gas can flow. Possible further fields of application relate, for example, to filters of combustion and heating systems, which, like filters used in motor vehicles, have to be subjected to maintenance at regular intervals.
    The cylindrical device 1 comprises a base 6, on which an upper housing part 7 is arranged. The device 1 usually has a height of about 100 to 180 cm, wherein the base 6 extends approximately to half the height. The upper housing part 7 comprises on the outside a jacket 8, which is preferably transparent, in order to allow a view into the interior of the device 1, in particular on an object 2 to be cleaned. The jacket 8 can be made of a transparent plastic, for example a polycarbonate, or be formed of glass. The upper housing part 7 is closed by a head-side cover plate 9. The upper housing part 7 together with a lining of the base 6 together form a housing 3. 9 • • I ··
    Thus, the object to be cleaned 2 can be positioned within the housing 3, the jacket 8 may have a closable opening. For example, the jacket 8, which has a circular cross-section, may be formed with a door. However, it is preferable for the jacket 8 to have a slightly larger cross-section than the base 6 and to be vertically movable over it in order to release the housing 3 in the region of the upper housing part 7. The object 2 can then be readily positioned inside the device 1, especially since the jacket 8 has a maximum height equal to the base 6 and thus can be moved vertically with its upper end to an upper end of the base 6, for this purpose the jacket 8 is mounted on guide rails, which at the same time rigidly connect the head-side cover plate 9 with the base 6. If the jacket 8 is circular in cross-section as in the embodiment, three guide rails are expediently provided, which are offset from the center of the housing 3 and a longitudinal axis thereof viewed at an angle of 120 ° to each other. As a result, a stable guidance of the shell 8 is ensured when moving. So that the base 6 is accessible on the inside, this has two downwardly or optionally also to the side hinged doors 17, 18,
    The base 6 includes bottom-protruding fastening tabs 19 with openings.
    At this mounting tabs 19, the base 6 and the device 1 can be fixed in place. It is also possible that the device 1 alternatively or additionally on the bottom rolling or sliding elements, so that the device 1 is easily transportable within a site.
    Furthermore, a control and control console 12, which is highly schematized in FIG. 1, is provided which is fastened to the device 1 on a rear side of the base 6. With the control and control console 12 processes within the device 1 and the housing 3 can be controlled. To display data, the operating and control panel 12 in addition to a display, not shown.
    As can be seen in Fig. 2, in the upper part of the device 1 is a
    Observation device 28 is arranged, which is preferably höhenverstetlbar, pivotally and in a plane perpendicular to the longitudinal axis of the device 1 is movable. The observation device 28, eg, a camera, serves for an optical detection of one of the 10
    It can also be used to detect defects in the object 2. The observation device 28 is preferably also controllable from the control panel 12.
    In order to free an object 2 to be cleaned in the form of a filter or catalyst of adhering solids and / or liquids, a cleaning device 5 is provided, which is attached to the head-side cover plate 9 and / or the lateral guide rails, with the cleaning device 5, the will be explained in detail below, the object to be cleaned 2 can be acted upon with compressed air, so that in particular adhering particles are at least largely removable. Such a cleaning device 5 is advantageously provided both above a base 4 with a support surface 10, on which the object 2 is positioned for cleaning and for diagnosis purposes, and below the base 4 or support surface 10. But it is also possible that in particular only an upper cleaning device 5 is provided, under which the object 2 is positioned for cleaning. The support surface 10 is formed as a grid or lattice-shaped, so that escaping from the article 2 compressed air can escape down into the base 6. The base 4 with the support surface 10 may be pivotally mounted for easier positioning of the article 2 from the housing 3, as can be seen for example in Fig. 3 or 5. This makes it possible to place the article 2 on the horizontal support surface 10 in a particularly simple manner. In this connection, fastening means 11 can also be provided, which are arranged on the base 4 laterally of the horizontally swing-out support surface 10 advantageously at a constant distance from each other. As a result, the object 2 can be kept in a desired position during cleaning when compressed air or optionally also impacts are applied. In addition, a centering of the object along the longitudinal axis of the device 1 is possible.
    Simple examples of fastening means 11 are shown in FIGS. 6 and 7, which are arranged at an angle of 120 ° to one another and are particularly suitable for the usually round filters or catalysts. The fastening means 11 each have a radially engageable with the object 2 tail, so that the object 2 is positionally stable fixable without a lower surface thereof would be blocked. The end pieces of the fastening means 11 can be actuated hydraulically or pneumatically. But it is also possible that adjustable screws or other purely mechanically acting fastening means 11 are provided.
    In order to obtain in particular also statements about a qualitative state of the object 2 to be cleaned before, during and after a cleaning process, the base 4 can be finished with a balance or stored on a balance. It is possible, for example, as shown in Fig. 8 dargesteilt that the support surface 10, on which the object 2 is positioned during a cleaning process, is mounted on three in a Winkei of 120® offset from each other arranged weight sensors. It can then be festgestelit a weight of the object 2 before, but also during the cleaning process and tracked.
    For diagnostic purposes, it may further be provided that at least one light source 13 is provided below the grid-shaped bearing surface 10, with which a lower end 201 of the article 2 can be irradiated with light. The at least one light source 13 may be a headlight. It is also possible that, instead of a light source 13, a plurality of light sources 13 in the form of light-emitting diodes is provided so that a homogeneous illumination of the lower end 201 of the object 2 is provided. The at least one light source 13 is arranged on a plate 15, which is mounted with a rotatable and / or pivotable holder 16 on the base 6. A movement of the holder 16 or, a rotation and / or pivoting of the plate 15 and thus the at least one light source 13 is possible from outside the housing 3, in particular via the control panel 12, so that the plate 15 together with the at least one light source 13th can be turned to the side and / or swung during a cleaning of the article 2, if necessary, for diagnostic purposes, but in a position required for this purpose can be brought. Opposite the at least one light source 13 or the plate 15, viewed to the head-side cover plate 9 back, a likewise rotatable and / or pivotable mirror 14, for example, on one of the guide rails or the head-side cover plate 9 is attached. The mirror 14 can be positioned so that upon irradiation of the lower end 201 of the article 2, an upper end 202 of the article 2 outside the device 1 is observable, this is easily possible, especially since the jacket 8 is transparent. If the jacket 8 is not made of a transparent material such as a transparent plastic or glass, a viewing window is provided for this purpose. Instead of the mirror 14, a camera 12 or one or more light-sensitive sensors may also be provided, with the image of the upper end 202 of the object 2 picked up by the camera or sensors being expediently located on the control panel 12, via which the plate 15 with the at least one light source 13 and the mirror 14 or the camera or the photosensitive sensors can be brought into position.
    In Fig, 10, the cleaning device 5, which is positioned in Fig. 1 above the article 2, shown in more detail. An analogous second cleaning device 5 is located below the bearing surface 10, wherein this second cleaning device 5 is rotated 180 ° relative to that shown in FIG. The cleaning device 5 has a rotary-angle drive 503, which is attached to the head-side cover plate 9. On the rotary-angle drive 503, which is preferably pneumatically controlled and whose movement is adjustable via the control and control panel 12, a pivotable axis 502, which can be displaced by the rotary actuator 503 into a pivoting movement of at least 180 °, is mounted centrally. On the axis 502 two Geienkstäbe 505 are articulated at the ends of fulcrums 507. The torsion bars 505 each carry a compressed air nozzle 501 at an end opposite the pivot points 507, which are connected via compressed air hoses 504 to a compressed air reservoir, not shown. Moreover, the hinge rods 505 are each connected to a piston-cylinder unit 506, the other end of which is supported at about a center of the pivotable shaft 502. The piston-cylinder units 506 are pneumatically operable and can be simultaneously retracted and extended to pivot or pivot the axle 502. This makes it possible to completely pressurize a given circular surface, in particular an upper end 202 or a lower end 201 of an object 2 to be cleaned, or in a short time with compressed air, so that a good cleaning effect is achieved. In this case, a loading of an upper end 202 and a lower end 201 of the article 2 can be carried out so that the attacking from above and below air jets each on one axis Hegen. It is also possible, however, for the cleaning device 5 to be operated above the upper end 202 of the article 2 in an offset manner to a cleaning device 5 arranged and operating below the contact surface 10. The respective operating mode, which can be set via the operating and control panel 12, depends primarily on the structure of the object 2 to be cleaned, which may be, for example, a wall-flow filter or an open-pore metal foam filter. 13
    11, projections of the application lines generated by the compressed-air nozzles 501, for example at the upper end 202 of the article 2, are shown when the axis 502 is pivoted and the extension and retraction of the joint rods 505 is simultaneously shown. As can be seen, essentially an entire area of the object 2 is subjected to compressed air. If necessary, the object 2 can also be minimally displaced during the cleaning process, so that a center is also pressurized with compressed air. Alternatively, it is also possible for the cleaning device 5 to be displaced slightly parallel to the surface of the object 2 to be cleaned, so that the compressed air flowing out of the compressed-air nozzles 501 also covers the center.
    In addition to the components already mentioned, a device 1 according to the invention may also comprise further units, in particular for diagnostic or test purposes. In FIG. 12, for example, it is roughly illustrated that the device 1 may further comprise a labeling device 21, which is likewise located inside the housing 3 is arranged. With the labeling device 21, a cleaned and examined object 2 can be identified. With appropriate labeling of the object 2 can be recognized or identified in a repeated cleaning. It is then readily possible to compare characteristic values of the article 2 in the original state or after a previous cleaning with the current characteristic values. For example, a comparison can be made as to whether the article 2 again has the same weight after cleaning as after a previous cleaning or in the original state. If the weight is higher, then it can be concluded that in the article 2, for example, soot particles or ash particles are still present, which can not be removed with the cleaning device 5. In addition to the labeling device 21 or possibly integrated in this, a reading device can be provided so that the identification of the object 2, for example, a barcode, read and on the control and control panel 12, via which already stored data are accessible, can be output.
    FIG. 13 shows a highly schematic diagram of a further unit for the diagnosis of a cleaned article 2. The unit comprises a device 23 with a feed line and a frusto-conical end adjoining it, which can be placed on an object 2 so that its entire upper end 202 is covered. The device 14
    23 is disposed within the housing 3 and can be pivoted in if necessary. Below the support surface 10, a likewise pivotable measuring device 24 is provided, with which a number of particles in an air flow can be detected. During the test, a gas with a defined content of soot particles is injected via the device 23. With the measuring device 24 it is determined whether the article 2 meets the requirements for adsorption of soot particles.
    In Fig. 14, a further unit is shown, which may optionally be provided. The unit is a device 22 for injecting a hot gas into the article 2. This device 22 is used in particular when it is determined that an optimum weight of the article 2 is not yet present or from a measured weight it is concluded that in the article 2 still particles, such as soot particles! and / or ash teats, must be present. In this case, the device 22 is placed and applied via a supply line, not shown, the object 2 in the region of the upper end 202 over the entire surface with a hot gas whose composition is chosen so that it reacts as completely as possible with the suspected particle type.
    In Fig. 15, the base 6 is dargesteilt detail. The base 6 comprises in addition to the already explained plate 15 with the light sources 13 arranged thereon a filter 25. This filter 25 serves to filter the exhaust air when using the cleaning device (s) 5, so that no unpurified gas leaves the device 1. Furthermore, downstream of the filter 25, a vacuum blower 26 is provided. With the Unterdruckgebfäse 26 introduced into the device 1 compressed air is sucked through the filter 25 therethrough. Further, a dust collecting container 27 is provided, which is lower than the filter 25. The filter 25 as well as the dust collector 27, but in the event of a repair and the Unterdruckgebfäse 26 are freely accessible by opening the doors 17, 18.
    FIGS. 16 and 17 show sealing arrangements in the region of a head-side cover plate 9 and a lower end of the jacket 8. The jacket 8 has at one of the head-side cover plate 9 facing the end of two sealing rings 29, which provide for stop of the jacket 8 to the head-side cover plate 9 for a seal. Similarly, an annular seal 30 is provided at a lower end of the shell 8, which acts sealingly towards the base 4. Thus, when the jacket 8 is moved vertically upward, the gaskets 29, 30 strike the head-side cover plate 9 or the base 4 and thus ensure the desired sealing of the device 1 during a cleaning process.
    The device 1 may further comprise other components, for example a sensor for detecting combustible media in the article 2, and may optionally be part of a larger plant with a separate furnace used for a prone additional aftertreatment.
    A cleaning process with the device 1 proceeds as follows: First, an incoming inspection of the object 2 to be cleaned with weighing and labeling takes place, so that the corresponding data can be traced during a renewed maintenance. Furthermore, there is a detection of combustible media, since no fuel or engine oil in the object to be cleaned 2 should be present. If this is still the case, this is detected by the detector and output on the control panel 12 by display. As a consequence, this necessitates a changed process sequence, whereby the article 2 may need to be pre-cleaned. Furthermore, the data of the article 2, in particular its weight, are compared with the data of the new state and / or the data after a previous cleaning, if available. From a difference weight a soot or ash charge is calculated. Thereafter, the geometry of the object 2 is measured with the observation device 28, in particular the size and shape of the article 2. In this step, a coarse contamination with the observation device 28, usually a camera is determined by an image data evaluation takes place. The result of the Bifddatenauswertung is the basis for a subsequent cleaning program. In this step of the examination of the article 2 also already existing defects such as cracks can be detected. After the cleaning program has been calculated, end stops for the cleaning device 5 or a movement of the compressed-air nozzles 501 in a plane above and below the article 2 are calculated. Subsequently, a cleaning starts with the cleaning devices 5. During the cleaning process, a change in the weight is always measured. Furthermore, it can also be provided that a differential pressure measurement is carried out in order to continuously monitor a soot emission or a running cleaning. For example, as soon as the soot output or the weight remains constant within 16 predetermined tolerances, this first cleaning step is ended. It is then decided whether the object 2 is to undergo a post-purification, for example by exposure to a hot, reactive gas. It is also possible, as an alternative, that the object 2 is removed from the device 1 and heated in a separate oven in order to burn alifällige residues. This is followed by a weight control and a further fine cleaning with compressed air, whereby a degree of purification of more than 95% is usually achieved. Thereafter, a transmitted-light test is also carried out by means of the at least one light source 13 and preferably a camera in order, inter alia, to detect defects in the object 2. 10 In a final step, a documentation of the results, which can be stored on the control and control panel 12. Furthermore, the article 2 can be marked with the labeling device 21 as cleaned. Preferably, a barcode or other identification of the article 2 is applied at the same time, so that at a later time a unique identification of the article 2 is possible.
