    The subject invention relates to a device for cleaning a felt belt in a plant for producing a paper tape with a device for introducing a cleaning liquid into the felt belt and at least one suction device following in the direction of movement of the felt belt with a vacuum channel, through which the cleaning liquid is sucked out of the felt belt is, wherein the suction device is formed between the vacuum channel and the felt belt with suction channels, through which the cleaning liquid located in the felt belt is sucked.
    Equipment for the production of paper tapes contain a first region with at least one screen belt, on which a mixture of substances for the production of a paper tape is applied, wherein the screen belt with scraper trained suction boxes are assigned, through which water is sucked from the mixture, whereby the paper tape is produced. These machines further include a second area of felt belts in which the paper web and at least one felt belt are passed between press rolls, whereby moisture contained in the paper web is taken up by the felt belts, and also a third area in which the paper web is dried by means of drying rolls. Subsequently, the dried paper tape is wound on spools, divided into sheets and packed in boxes.
    Since the felt belts not only absorb moisture contained in the paper tape, but also get into this components of the mixture, in particular fiber material, by which the effectiveness of the felt belts is deteriorated, there is a need to provide in the trajectory of the felt belts devices for their cleaning. These devices comprise at least one device for introducing a cleaning liquid into the felt belts and at least one suction device following in the direction of movement of the felt belts, by means of which the cleaning liquid located in the felt belts is simultaneously sucked off with the foreign substances located in the latter. The suction device consists of a vacuum channel and a suction plate to which the felt belt is applied and over which the felt belt is passed. The suction plate is formed with suction channels, which are e.g. are formed by a plurality of slots extending transversely to the felt belt and located side by side in the direction of movement of the felt belt, or by a plurality or a plurality of openings located in the suction plate, in particular bores.
    In the operation of such a suction device, however, the fact occurs that the felt belts can not be completely cleaned of the foreign matter contained therein, whereby they contain more impurities in the course of operating time with the result that they are impermeable to the suction of the cleaning liquid. A new and therefore no contaminants containing felt is so permeable that in the vacuum channel, the required minimum vacuum can only be produced if only a few suction channels are provided for the suction of the liquid in the suction plate or the entire cross section of the suction channels is low.
    With increasing operating time of the felt belt and thus increasing load on the felt belt by foreign matter, however, the permeability of the felt belt is reduced, which is why that portion of the felt belt on which the suction force acts, must be increased. This is accomplished by increasing the overall cross-section of the effective suction channels.
    According to the known prior art, the suction plates are formed with suction channels, the entire cross-section is so large that even when a heavily loaded with foreign material felt on this the required suction force acts. However, in order to maintain the required vacuum for operation with a new and thus free of foreign matter felt in the vacuum duct, the suction channels located in the suction plate are initially partially closed and are with increasing load on the felt and thus reducing permeability of the Filzbandes the initially closed suction channels successively opened.
    For this purpose, it is known to assign sealing strips to some of the suction channels located in the suction plate, by means of which the suction channels are at first partially closed, the sealing strips being removed successively with increasing operating time. Known felt belts have a width of up to 12 m. Suction slots in suction plates have a width of e.g. 10 mm to 18 mm. Sealing strips, which e.g. made of polyethylene, in this case e.g. a length up to 12 m and a cross section of 10 mm to 18 mm x 20 mm.
    However, there is the difficulty that it is not possible during operation of the system to remove these sealing strips, since they are pressed due to the pressure prevailing in the vacuum suction device to the suction plate with very high pressure and because they by the means of the cleaning liquid the foreign material removed from the felt belt are glued to the suction plate.
    It is also known to provide successively two suction devices, wherein at first only one of them is turned on and then, as soon as the screen belt is heavily loaded with foreign matter, the second suction device is switched on.
    The subject invention is therefore based on the object to provide a suction device, wherein during operation of the system individual suction channels, which are initially closed, can be opened during operation without difficulty or even closed. This is inventively achieved in that at least one of the suction channels is associated with at least one inflatable valve body, in the inflated state, the suction channel is closed and is opened by the vented state of the suction channel.
    Preferably, the suction channel is designed as a transverse to the felt belt aligned slot and the valve body is formed as an inflatable tube, wherein the suction channel extends across the width of the felt belt.
    The suction channel may further be formed by at least two transverse to the felt belt, contiguous slots or openings, in particular holes.
    According to a preferred embodiment, at least one suction plate extending transversely to the felt belt, which is formed with suction channels, is attached to the suction device. Furthermore, the at least one valve body, which is designed in particular as a hose, is preferably formed with a projecting bar, by means of which it is clamped between the housing of the vacuum channel and the suction plate.
    Furthermore, between the housing of the vacuum channel and the suction plate, at least one support strip for the at least one valve body, which is in particular designed as a hose, can be provided, to which the valve body is attached. In this case, the valve body may be attached to the support bar by gluing.
    According to a further embodiment, at least one valve plate, to which a valve body, in particular a hose, is attached, mounted on the support strip, which is adjustable by the valve body, wherein it is pivotable through the inflatable valve body in which the associated mammal occlusive position. Furthermore, the support bar can be screwed to the housing of the vacuum channel. Furthermore, the suction plate and the support strips may be formed with associated grooves and springs, by means of which they are secured together. In this case, the grooves and springs are preferably aligned transversely to the felt belt, whereby the suction plate is displaceable transversely to the felt belt.
    The object of the invention is explained below with reference to exemplary embodiments illustrated in the drawing. 2 shows a device for the production of a paper tape, in a schematic representation, FIG. 2 a device according to FIG. 1 for introducing a cleaning liquid into felt belts and a suction device, in relation to FIG. 2 shows the suction device according to FIG. 2, in relation to this enlarged scale and with a control system assigned thereto, FIG. 3, FIG. 3A, FIG. 3B, shows a first embodiment of the suction device according to FIG. FIG. 4B shows a second embodiment of the suction device according to FIG. 2A in a reduced scale compared to FIG. 2A and in three different operating positions, FIG. in a vertical section, FIG.5, FIG.5A, FIG.5B, a third embodiment of the suction device according to FIG.2A in comparison with FIG.2A reduced scale and in three different operating positions, in a vertical section.
    The plant shown in FIG. 1 for producing a paper tape has a first contact part 1, in which a self-contained screen belt 11 is guided over deflecting rollers 12, wherein the screen belt 11 suction boxes 13 are assigned. On the screen belt 11 is a fabric material for producing a paper tape 10, which is withdrawn by the suction boxes 13 in this befindliches water.
    Since the plant part 1 is not relevant to the subject invention, only the end region is shown in the drawing. To the first part of the system 1, a second system part 2, 2a, 2b connects, to which the paper tape 10 is transferred.
    In the second part of the plant 2, 2a, 2b are felt belts 21, 21a, 21b, which are guided in the direction of the arrows via guide rollers 22, 22a, 22b and which are each closed in itself. In addition, press rollers 23, 23a, 23b, 23c are provided in the contact part 2, 2a, 2b, which are each assigned in pairs to one another. Furthermore, tensioning rollers 24, 24a, 24b are provided, over which the felt belts 21, 21a, 21b are guided and by means of which they can be tensioned.
    From the first part of the plant, the paper tape 10 is transferred in the second part of the plant 2, 2a, 2b to the felt belt 21. As a result, the paper tape 10 passes between the felt belts 21, 21a, with which it is pressed by means of the press rollers 23, 23a, whereby moisture present in the paper tape 10 is discharged to the felt belts 21, 21a. The paper strip 10 then passes with the felt belt 21 between the press rollers 23, 23b, through which it is pressed with the felt belt 21. Furthermore, the paper tape 10 passes with the felt belt 21b between the two press rollers 23b, 23c. Thus, moisture is released from the paper tape 10 to the felt belts 21, 21a, 21b.
    To the second plant part 2, 2a and 2b, a third contact part 3 connects, in which there are a plurality of drying rollers 31, over which the paper tape 10 is guided, whereby it is further dried.
    The paper belt 10 located on the screen belt 11 has a dry content of about 20% at the end of the first system part 1. At the end of the second plant part 2, 2a, 2b, the paper tape 10 has a dry content of about 50% to 55%. In the third plant part 3, the paper tape 10 is brought to a dry content of about 93%.
    Since from the paper tape 10 in the felt belts 21, 21 a, 21 b not only moisture, but also in the paper tape 10 located impurities such as pulp fibers and other paper components, such as fillers, resins, ashes, printing ink pass, there is a need, the felt bands 21, 21a, 21b to allocate devices 4, 5 for their cleaning, the structure and operation of which is explained below.
    As shown in FIG. 2, such a device for cleaning a felt belt 21, 21a, 21b has at least one spraying device 4, 4a for introducing a cleaning fluid into the felt belt 21, 21a, 21b and in the direction of movement of the felt belt 21, 21a, 21b Subsequently, at least one suction device 5. 2, a first spraying device 4, by means of which the felt belt 21, 21a, 21b is acted upon by a wide jet 41a, and a second spraying device 4a, with which the felt belt 21, 21a, 21b is acted upon by a narrow jet 41a, shown. The loading of the felt belt 21, 21a, 21b takes place in each case over the entire width of the felt belt 21, 21a, 21b. The cleaning liquid consists of water, which is optionally provided with additives, such as solvents.
    The suction device 5 has a housing 51 with a vacuum channel 52, in which a negative pressure of - 200 millibar to - 600 millibar is generated. At the top of the housing 51, an opening 53 is provided, which is enclosed by a frame 60 and which is closed by a suction plate 54 formed with suction channels 55, 56, 57. The felt belt 21, 21a, 21b is moved along the top of the suction plate 54. The suction channels 56, 57 are associated with valve body 58, 59, through which these two suction channels 56, 57 are closed.
    The operations of the spraying devices 4, 4a and the suction device 5 are as follows:
    The felt belt 21, 21a, 21b is moved past the spraying devices 4, 4a and subsequently to the suction device 5. By means of the injection devices 4, 4a, a cleaning liquid is applied to the felt belt 21, 21a, 21b, which penetrates into the felt belt 21, 21a, 21b. By means of the at least one suction device 5, this cleaning liquid is sucked out of the felt belt 21, 21a, 21b, whereby foreign substances located in the felt belt 21, 21a, 21b are removed. However, in the felt belt 21, 21a, 21b with increasing operating time more and more shares of foreign matter, whereby this is less permeable. For this reason, the area of the felt belt 21, 21a, 21b to which a suction force is applied by the suction means 5 must be increased in order to perform effective cleaning of the felt belt 21, 21a, 21b by means of the cleaning liquid.
    This requirement is met by the fact that for the cleaning of a new and thus very permeable felt belt 21, 21 a, 21 b, the suction channels 56, 57 are closed by means of the valve body 58, 59, as shown in FIG. This ensures that the vacuum generated in the vacuum channel 52, which is required to achieve the required suction force, can be maintained. However, as soon as the permeability of the felt belt 21, 21a, 21b decreases due to the foreign matter remaining therein, thereby reducing the cleaning force caused by the extracted cleaning liquid, the area of the suction force acting on the felt belt 21, 21a, 21b must be increased. For this purpose, the valve bodies 58, 59 associated with the suction channels 56, 57 are brought into their open position, whereby the surface of the felt belt 21, 21a, 21b, on which a suction force is exerted, is increased.
    The design of the suction device 5 and its mode of action will be explained in more detail below with reference to FIG.
    The housing 51 of the suction device 5 is formed on its upper side with the frame 60 which surrounds the opening 53. On this frame 60 side of the opening 53 located support strips 61, 62 are provided, which are fastened by means of bolts 63 on the frame 60. The suction plate 54 and the support bars 61, 62 are formed with mutually associated grooves 54a and springs 61a, 62a.
    The valve bodies 58, 59 are each formed by an inflatable tube, which is rectangular in cross-section and which is each formed with a laterally projecting tab 58 a, 59 a, which is located between the frame 60 and the strips 61, 62, whereby the tubes 58 , 59 are attached. The inflatable tubes are made of a rubber or plastic material, e.g. ethylene-propylene-diene rubber (EPDM) or nitrile-butadiene rubber (NBR).
    The vacuum channel 52 is acted upon by a vacuum pump with a vacuum, which is measured by a measuring device 64. The output of the measuring device 64 is applied to a control unit 65. The hoses 58, 59 are connected via lines 70, 71 either to a compressed air pump + P, whereby they are inflatable, or they can be connected to a vacuum pump -P, whereby they are vented. For this purpose, two lines 70a, 70b are connected to the line 70 and are connected to the line 71, two lines 71a, 71b, wherein the lines 70a, 71a are connected to the compressed air pump and the lines 70b, 71b to the vacuum pump. In the lines 70a, 70b and 71a, 71b are valves 72a, 72b and 73a, 73b, which are controlled by the controller 65. As soon as the valves 72a, 73a are opened, the hoses 58, 59 associated with the suction channels 56, 52 are subjected to compressed air. As a result, they are inflated, whereby the suction channels 56, 57 are closed. This is necessary if the permeability of the felt belt 21, 21a, 21b is still so great that to maintain the vacuum in the vacuum channel 52, only the suction channels 55 should be open, whereas the suction channels 56, 57 must be closed.
    However, as soon as the permeability of the felt belt 21, 21a, 21b for the cleaning liquid has been reduced by the fact that there are increasingly foreign substances in it, and therefore the area of the felt belt 21, 21a, 21b, on which the suction force is exerted, must be increased, the valves 72b, 73b are opened, whereby the tubes 58, 59 are vented. As a result, the suction channels 56, 57 are released, whereby the felt belt 21, 21a, 21b is also acted upon by the suction channels 56, 57 through suction.
    Due to the fact that the valve bodies are inflatable, wherein they are formed in particular by inflatable hoses, those suction ducts, which are associated with these valve body, can be released at any time during operation of the plant for paper production, whereby the adhering to the prior art difficulties in the opening of other suction channels are avoided.
    Since the suction plate 54 with grooves 54a and the support bars 61, 62 with the grooves 54a associated springs 61a, 62a are formed, the suction plate 54 can be pulled out laterally, whereby the tubes 58, 59 can be mounted in a simple manner.
    The mode of operation of such a suction device 5 with reference to a first embodiment is explained below with reference to FIG. 3, FIG. 3A, FIG.
    According to FIG. 3, the two tubes 58, 59 are supplied with compressed air, as a result of which they are inflated. As a result, the suction channels 56, 57 are closed. This is necessary when the felt belt 21, 21a, 21b does not or only slightly contains foreign substances, so that it is very permeable to the suction of the cleaning liquid.
    However, as soon as the felt belt 21, 21a, 21b with increasing operating time contains more and more foreign substances, whereby its permeability to the cleaning liquid is reduced more and more, the tube 58 is vented for the time being, whereby the suction channel 56 is released and on the felt belt 21, 21a, 21b is also exercised over this a suction force. This operating position is shown in FIG.3A.
    Subsequently, the tube 59 is vented, whereby the suction channel 57 is released and on the felt belt 21, 21 a, 21 b also exerted on the suction passage 57, a suction force. This operating position is shown in FIG. 3B.
    In the FIG.4, FIG.4A, FIG.4B a second, compared to the FIG.3, FIG.3A, FIG.3B modified embodiment is shown. In this case, the support strips 61, 62 are formed with extensions 61a, 62a, to which the tubes 58, 59, e.g. are attached by gluing.
    The operation of the tubes 58, 59 and their operations are the same, as explained with reference to FIG.3, FIG.3A, FIG.3B.
    A third embodiment in the construction of the hoses acting as valve bodies is explained below with reference to FIG. 5, FIG. 5 A, FIG. 5B. Here are located between the suction plate 54 and the support bars 61, 62 hinge-like elements 80, 82, each with two plates 81, 81a and 83, 83a, which are mounted on axle bolts 81b, 83b. The plates 81, 83 are located between the suction plate 54 and the support bars 61, 62 and are thereby secured. The plates 81a, 83a are pivotable relative to the plates 81, 83. Between the plates 81a, 83a and the support strips 61, 62 are tubes 58a, 59a. When the tubes 58a, 59a are inflated, the plates 81a, 83a abut against the suction plate 55, whereby the suction channels 56, 57 are closed. As soon as the tubes 58a, 59a are vented, the plates 81a, 83a are lifted off the suction plate 55, whereby the suction channels 56, 57 are opened.
    The suction channels located in the suction plate 55 may slots extending through the widths of the felt belts, through a plurality of slots which extend across the widths of the felt belts, or through a plurality or a plurality of openings, in particular holes, which over the widths of the Filzbänder are arranged to be formed. A part of these suction channels are inflatable valve body, in particular in the form of
    Assigned hoses, by means of which individual suction channels can be opened.
    The particular advantage of such a device is that it is possible due to the inflatable or ventable valve body, which are associated with the suction channels located in the suction plate to open the suction channels during operation of the system to pressurize enlarged surfaces of the felt belts to be able to. As a result, it is not necessary to provide a further suction device, which is switched on with increasing load on the felt belts with foreign substances.
