    Arrangement for cleaning a filter
    The present invention relates to an arrangement for cleaning a filter, in particular a round filter, according to the closer defined in the preamble of claim 1 Art.
    Filters are used for example in vehicle technology versatile. In motor vehicles round filters are used for air purification. For cost reasons, it is customary that such round filters are regularly cleaned while reducing the air flow rate in order to increase their service life. It is known that dirty round filter, for example, be cleaned manually by means of compressed air. However, this is time consuming and labor intensive. In addition, the environment is polluted due to the resulting fine dust.
    For example, from document AT 403 014 B, a cleaning device for filters and filter mats is known in which air jet nozzles are provided, which are moved along the longitudinal axis of the filter. For this purpose, the filter is provided in a cleaning chamber on a rotatable base plate, wherein along the filter inside a longitudinally movable inner cleaning nozzle and a movable along the outside of the filter outer cleaning nozzle are provided. Furthermore, the cleaning chamber is associated with a suction.
    It has been found that the cleaning effect with the known cleaning device is very low, since only a quasi-line blowing of the surface of the filter inside and the filter outside of the filter takes place through the only movable in the longitudinal direction of the filter cleaning nozzles. Consequently, the entire surface of the round filter can not be cleaned or only with considerable expenditure of time, which adversely affects the cleaning costs.
    The present invention is based on the object to propose an arrangement of the type described above, in which a quick and inexpensive complete cleaning of the filter surface is realized.
    This object is achieved by the features of claim 1, wherein advantageous embodiments of the dependent claims and the description and the drawings.
    Accordingly, an arrangement for cleaning filters, in particular circular filters or the like with at least one cleaning chamber with a drivable turntable for receiving the filter and with at least one of the inner and / or outer surface of the filter blowing cleaning nozzle proposed. According to the invention, at least one rotor with at least one cleaning nozzle is provided for enlarging the blowing surface on the inside and / or on the outside of the filter.
    With the arrangement according to the invention an air filter cleaning system z. B. proposed for motor vehicle round filter of different dimensions. By rotating the filter on the turntable and by additionally rotating the rotor and the at least one cleaning nozzle attached thereto, the air filter lips on the surface of the filter to be cleaned can advantageously open and the dust present can be thoroughly blown out by the impinging air flow. In addition, the blowing surface is increased due to the rotation of the air-flow cleaning nozzles, so that a particularly simple and quick cleaning option results with very high cleaning performance. Accordingly, with the proposed arrangement readily filters of machines, such. As excavators, wheel loaders or the like, which are used in a particularly dusty environment. With the arrangement according to the invention thus resources can be saved and ultimately the environment be spared.
    Preferably, the axis of rotation of the rotor is oriented at a predetermined angle to the longitudinal axis of the filter, the angle having a value of about 80 degrees to 100 degrees, preferably 90 degrees. In the preferred case, the axis of rotation is thus oriented at right angles to the filter axis or to the longitudinal axis of the filter, so that the air outlet jet from the cleaning nozzles impinges approximately perpendicular to the surface of the filter. It has been shown that the alignment at right angles to the axis of rotation or the air outlet jet and the filter axis allows a particularly high cleaning effect by the blowing off or pushing away adhering dust particles. As a result, this results in substantial cleaning advantages over known arrangements.
    In the proposed arrangement is thus realized by each rotating rotor with at least one or more cleaning nozzles an approximately circular movement of the cleaning nozzles with selectable diameter about the axis of rotation depending on the radial arrangement position of the cleaning nozzle on the rotor or depending on the choice of the rotor diameter. The simultaneous rotational movement of the round filter on the turntable results in an approximately annular blowing surface along the circumference, the width of which corresponds approximately to the rotor diameter or twice the radial distance of the cleaning nozzle from the axis of rotation. If the rotor is adjusted simultaneously in the longitudinal axis direction of the filter, a helical course results at the circumference of the filter. The generated blowing surface not only enables optimum cleaning of the surface of the round filter but also significantly reduces the cleaning time due to the increased blowing surface.
    Preferably, a rotor with a plurality of cleaning nozzles for cleaning the round filter can be assigned to the outer surface of the round filter and the inner surface in each case. To clean the entire surface of the round filter, the rotors, which are associated with the inner surface and the outer surface of the round filter, can be moved in the longitudinal axis direction, for example via an associated lifting drive or the like. Due to the intended longitudinal adjustment of the rotors can be dispensed with further rotors in an advantageous manner. Preferably, the cleaning phases of the inner and outer rotors can be carried out simultaneously or else one after another and can be repeated several times depending on the degree of soiling.
    However, it is also conceivable that a plurality of rotors arranged one above the other in the longitudinal axis direction of the filter are arranged in the interior of the round filter and / or also on the outside of the round filter, without an adjustability of the rotor in the longitudinal axis direction being necessary. In this way, the linear actuators can be saved.
    The rotational speed of the turntable and the lifting speed of the rotor and the rotational speed of the rotor or the cleaning nozzles can be adjusted accordingly to achieve optimum, adapted to the respective filter to be cleaned cleaning performance.
    The present invention will be further explained with reference to the figures. Show it:
    Figure 1 is a schematic view of a possible embodiment of an inventive arrangement with the inner surface and the outer surface of the round filter associated rotors;
    FIG. 2 shows an enlarged schematic partial view of the arrangement with a rotor assigned to the outer surface of the round filter;
    Figure 3 is a schematic detail view of the rotor with two cleaning nozzles;
    Figure 4 is a schematic partial view of the arrangement with the rotor in a lower adjustment position;
    Figure 5 is a partial view of the arrangement with the rotor in an upper adjustment position; and
    Figure 6 is a schematic detail view of the air guide element.
    In the figures 1 to 6, an arrangement for cleaning a filter, in particular a round filter 1 is exemplified with reference to several views.
    The arrangement comprises a cleaning chamber 2 with a turntable 4 for receiving the round filter 1. The surface of the turntable 4 is provided, for example with foam rubber or the like, to lie close to the bottom of the round filter 1. Furthermore, one of the top of the round filter 1 associated pressing member 13 is provided, with which the round filter 1 can be pressed onto the turntable 4. Preferably, the pressing member 13 is also provided with elastic material, such as sponge rubber or the like, so that the top of the round filter 1 as possible airtight against the pressing member 13. The cleaning chamber 2 has a closable door 14.
    To clean the round filter 1, a first rotor 6 are in the illustrated embodiment with z. B. two cleaning nozzles 5 of the outer surface of the round filter 1 and a second rotor 6A with z. B. two cleaning nozzles 5A associated with the inner surface of the round filter 1, wherein theoretically each cleaning nozzle 5, 5A on each rotor 6, 6A would be sufficient. The axes of rotation 7, 7A of the rotors 6, 6A are aligned approximately at an angle φ of 90 degrees to the longitudinal axis or axis of rotation 8 of the round filter 1. Accordingly, the air outlet jet from the cleaning nozzles 5, 5A respectively impinges approximately perpendicularly on the inner and outer surface of the round filter 1. Because the interior of the round filter 1 is sealed by the pressing element 13 and the turntable 4, the interior of the round filter 1 builds up the exiting from the cleaning nozzle 5 A of the rotor 6 A air to an overpressure, so that the round filter 1 is blown from the inside out. The air emerging from the cleaning nozzles 5 of the first or outer rotor 6 causes a detachment of the adhering to the outer surface of the round filter 1 particles. As a result of the overpressure acting in the interior, the particles are virtually blasted off the outer surface of the round filter 1 and removed.
    In the illustrated embodiment of the arrangement according to the invention, the longitudinal axis 8 of the round filter 1 is aligned vertically on the turntable 4 and the axis of rotation 7, 7A of each rotor 6, 6A horizontally in the cleaning chamber 2. Each rotational axis 7, 7A of the first rotor 6 and the second rotor 6A is adjustable via an associated lifting drive 9, 9A in the longitudinal axis direction of the round filter 1. This is shown by way of example in Figures 2 and 4 and 5, wherein the adjustment and directions of rotation are indicated by arrows.
    Both the first rotor 6 and the second rotor 6A each have two mutually radially opposite cleaning nozzles 5, 5A. The cleaning nozzles 5, 5A are thus spaced apart radially relative to the axis of rotation (7, 7A), wherein the radial distance of the cleaning nozzles 5, 5A corresponds approximately to the rotor diameter. By the air admission of the cleaning nozzles 5, 5A of the respective rotor 6, 6A and the air emerging thereby from the nozzles the respective rotor 6, 6A is set into rotation. To set a respectively desired rotational speed of the respective rotor 6, 6A radially adjustable weights 15 or the like are provided on each rotor 6, 6A. Depending on the arrangement position of the weights 15 so that the rotational speed can be changed. It is also possible to change the rotational speed by the amount of air supplied. Furthermore, a separate drive of the rotors 6, 6A would be conceivable.
    It is clear from FIG. 2 and from FIGS. 4 and 5 that the rotor 6 is arranged offset with respect to the vertically aligned lifting axis 22 with the horizontally oriented rotational axis 7 offset by means of a holder 13. Preferably, the axis of rotation 7 is arranged laterally offset from the lifting axis 22 such that the axis of rotation 7 and the lifting axis 22 have no common point of intersection. By such an offset arrangement of the rotor 6, the cleaning performance is further increased. Preferably, the rotor 6 is disposed inside the round filter 1 with respect to the rotor 6A such that the discharge jet of the cleaning nozzles 5 of the rotor 6 and the discharge jet of the cleaning nozzles 5A of the rotor 6A are directed in the same direction.
    FIG. 3 is an enlarged view of an example of an example of one of the rotors 6, 6A for cleaning the round filter 1. It can be seen from FIG. 3 that the distance between the opposing cleaning nozzles 5, 5A of each rotor 6, 6A forms the diameter D1, D2 of the blowing surface 20 on the round filter 1, two different diameters D1, D2 or distances of the cleaning nozzles 5 being shown by way of example 5A are indicated. To change the air outlet angle W1, W2 at each cleaning nozzle 5, 5A is provided that they are adjustably arranged on the respective rotor 6, 6A. In FIG. 3, for example, two different air outlet angles W1, W2 at the cleaning nozzles 5, 5A are indicated.
    Furthermore, it can be seen from FIG. 3 that at least the rotor 6 is adjustable in length along the axis of rotation 7, which is indicated by a corresponding arrow. For this purpose, for example, a clamping screw 16 is seen on the holder 3 in front to adjust the rotor 6 along the axis of rotation 7. About the bracket 3, a spatially offset arrangement of the rotor 6 is attached to the telescopic tube 19 to adjust the rotor 6 via the associated lifting drive 9 in the longitudinal axis direction, which is shown in particular in Figure 4 and 5.
    The rotational speed of the turntable 4 and the lifting speed for adjusting the respective rotor 6, 6A in the longitudinal axis direction is selected such that each time the turntable 4 rotates, an overlapping region 21 extending in the longitudinal axis direction of the round filter 1 is wound in the helical face 20 of the round filter 1 which is shown in Figures 4 and 5 by the marked overlap region 21.
    As can be seen, for example, from FIGS. 1 and 2, an air guide element 10 arranged below the rotor 6 is provided for guiding the air flow to the surface of the round filter 1, so that the air flow is directed away from the turntable 4 onto the filter surface. With the air guide element or adjusting plate 10 shown in FIG. 6, the penetration of the dust into the round filter 1 is prevented, since the air flow emerging from the cleaning nozzles 5, 5A is always applied to the round filter 1. The air guide element 10 is adjustable in order to be adapted to the respective outer diameter of the round filter 1 and to the respective rotor position. Furthermore, the area of the air guiding element 10 facing the round filter 1 is provided with a radius 23, preferably of an elastic material, in order to be optimally adapted to the radius of the outer surface of the round filter 1. The air guide element 10 is adjustably mounted in the cleaning chamber 2 via an adjusting element 24.
    The adjustment element 24 comprises an adjustment region, which is connected to the air guide element 10, and a fixed in the cleaning chamber 2 mounting region. The adjustment range can be locked in a predetermined adjustment position via adjustment means on the attachment area. At the adjustment of the radius 23 of the air guide 10 is provided.
    As can be seen in particular from FIG. 6, the adjusting element 24 permits a movement directed in the direction of the round filter 1, so that an optimal orientation of the air guiding element 10 on the filter surface below the first rotor 6 is made possible in accordance with the radius of the round filter.
    Below the turntable 4, a dust collecting chamber 11 is provided which is separated from the cleaning chamber 2 by a center plate 18. The dust collecting chamber 11 has a connecting piece 12 for connection to the suction. As a suction, a mobile suction device or a stationary system with appropriate air treatment can be used.
    In order to produce an advantageous suction effect in the cleaning chamber 2, air inlet slots 17, 17A for forced air guidance can be provided both on the upper side and on the side walls of the cleaning chamber 2. In this way, the dust is fed into the dust collecting chamber 11 as fast as possible.
