  • the cleaning device stands out through at least one additional nozzle, by means of which one for cleaning the Suction device serving - preferably liquid - treatment medium in the Suction chamber and / or can be introduced into a suction line of the suction device.
  • the treatment medium introduced into the suction line from the additional nozzle For example, rinse water, rinses the suction line in such a way that at the Contamination adhering to the inner surface of the suction line, for example Material fibers, adhesives, other additives or the like, by the Cleaning nozzle has been detached from the conveyor belt using the cleaning medium detached and can be rinsed out of the suction line. This can clogging of the free cross section of the suction line can be prevented.
  • cleaning medium can lime, which is present in bound form in the cleaning medium, in the Store the suction line so that the suction line can also be clogged.
  • the treatment medium introduced by the additional nozzle makes it possible to to solve these limescale deposits in the suction line or their To avoid education. Due to the cleaning effect of the treatment medium can in some cases on cleaning the suction device, especially the Suction line, completely dispensed with, but at least the distances between the Cleaning intervals are extended. This is a reduction in Operating costs of the machine for the production of the material web possible.
  • the Treatment medium can advantageously function properly Cleaning device can be guaranteed even after prolonged operation without the cleaning device or parts thereof disassembled and cleaned Need to become.
  • the cleaning device has due to the "self-cleaning" a high level of functional reliability by means of the additional nozzles.
  • a first exemplary embodiment of the cleaning device is preferred, which is characterized in that the additional nozzle on the jacket of the suction chamber surrounding suction cup is arranged. It is possible that the additional nozzle Injects treatment medium directly into the suction line, for example in the end area of the suction line opening into the suction space. In another Design variant is provided that the treatment medium in the suction chamber is introduced and by means of the suction of the suction device in the Suction line arrives.
  • the nozzle jet flowing out of the additional nozzle essentially is directed parallel to the inner surface of the suction cup.
  • the jet or the flow of the treatment medium lies on the inner one Lateral surface and can thus in the direction of the opening in the suction chamber Suction line of the suction device can be directed. This can prevent that the treatment medium used for cleaning the suction line on the Conveyor belt arrives. At the same time, the inner surface of the suction cup cleaned and a deposit of impurities in the suction chamber on the Suction cup can be prevented.
  • the device for cleaning a conveyor belt described below can be generally related to a machine for manufacturing a Material web are used. It is assumed here purely by way of example that the cleaning device used within a paper making machine becomes.
  • Figure 1 shows a schematic section of a first embodiment of a hereinafter referred to as cleaning device 1 device for cleaning of a conveyor belt 3 in cross section.
  • the cleaning device 1 can for any conveyor belts of the paper making machine can be used, for example for sieve belts or felts of a sieve or a press or dryer section of the paper making machine.
  • the Cleaning device 1 comprises a nozzle head rotatable about its longitudinal axis 5 7, which has a nozzle arrangement, not shown. This can be a or several tangentially aligned driving nozzles to generate a rotational movement include as well as one or more cleaning nozzles that the conveyor belt 3 with a gaseous or liquid cleaning medium.
  • the cleaning medium is a liquid, for example, 20 ° C to 90 ° C warm water.
  • the nozzle head 7 can be mounted in a stationary manner, that is to say it can rotate neither about its longitudinal axis 5, nor about another axis.
  • the nozzle head 7 is connected via a high-pressure line 11 to one that is not shown High pressure pump connected to the drive and cleaning nozzles with an under a pressure of preferably 100 bar to 1000 bar of standing liquid.
  • the nozzle head 7 is surrounded by a cylindrical suction bell 13 which a suction line 15 opening into the interior of the suction bell 13 with one not suction device shown is connected.
  • a suction bell 13 open to the edge Suction chamber 19 formed.
  • the Additional nozzle 23 On the jacket 21 of the suction bell 13 there is an additional nozzle 23 arranged, which opens into the suction chamber 19 and with a supply line 25 a low-pressure pump, not shown, is connected, by means of which the Additional nozzle 23 with a pressure of preferably 5 bar to 100 bar standing, gaseous or liquid treatment medium can.
  • the Treatment medium is so-called rinse water.
  • the flow of out of the Additional nozzle 23 emerging rinse water is indicated by arrows 27.
  • the additional nozzle 29 which opens into the interior of the suction line 15 and - like the additional nozzle 23 arranged on the jacket 21 of the suction bell 13 - via a Supply line 25 is in fluid communication with the low pressure pump.
  • the Additional nozzle 29 is also with the pressurized rinse water, the latter the nozzle jet flowing out of the additional nozzle 29 is indicated by arrows 33, acted upon.
  • the nozzle jet hits the additional nozzle 29 in an obtuse angle on the inner surface 35 of the suction line 15 Even strongly adhering dirt is safely removed and with the treatment medium washed away. It is also possible that the jet of the additional nozzle 29 in one acute angle impinges on the inner surface 35, so that the contaminants from the Inner surface 35 are quasi peeled.
  • the cleaning device 1 When the cleaning device 1 is in operation, they are arranged on the nozzle head 7 Driving nozzles and the cleaning nozzle via the high pressure line 11 with under pressure standing liquid acts, which leads to the nozzle head 7 around its Longitudinal axis 5 rotates and that guided past the cleaning device 1 Conveyor belt 3 from the cleaning nozzle at the high speed escaping liquid is applied.
  • the following are general material fibers, particles, adhesives and others called impurities Aggregates or the like detached from the conveyor belt 3.
  • impurities Aggregates or the like detached from the conveyor belt 3.
  • additional nozzle 29 added rinse water.
  • the rinse water prevents deposition of the contaminants on the inner surface 35 of the Suction line 15 or removes adhering impurities. Thereby clogging of the suction line 15 is prevented in an advantageous manner, so that the Desired function of the cleaning device 1 even after prolonged operation maintained and faults can be safely avoided.
  • the additional nozzles 23, 29 make no contribution to cleaning the conveyor belt 3 afford, but the introduction of additional liquid in the suction line 15th serve the contaminants detached from the conveyor belt 3 from the Suction line 15 rinsed out.
  • the treatment medium will be removed only at intervals To let additional nozzles 23, 29 emerge. This measure can reduce consumption of the treatment medium, for example only slightly contaminated Conveyor belts can be reduced. Basically, it is possible that the Cleaning device 1 only an additional nozzle in the suction line or on Sheath of the suction cup is arranged. Of course you can do more As two additional nozzles are provided, the rinse water in the Insert the suction device in the area that has been vacuumed.
  • FIG. 2 shows a schematic plan view of a part of that shown in FIG. 1 Cleaning device 1.
  • the same parts are provided with the same reference numerals, see above that in this respect reference can be made to the description of FIG. 1.
  • the one from the Auxiliary nozzle 23 flowing into the interior 19 nozzle jet runs as with Arrows 27 indicated - tangential to the inner lateral surface 39 of the suction cup 13, what has the consequence that the flow of the treatment medium to the inner Shell surface 39 of the suction cup 13 creates and thus parallel to the inner shell surface 39 along this, that is around the nozzle head 7, in the direction of that in FIG. 2 not suction line 15 shown is guided.
  • the additional nozzles 23, 29 described with reference to FIGS. 1 and 2 have preferably a diameter of 1 mm to 5 mm.
  • the diameter of the with a cleaning nozzle which can be acted upon under high pressure and the diameter of the driving nozzles described in FIG. 1 for generating a Rotational movement of the nozzle head 7 are preferably less than 1 mm.
  • the water treatment plant includes a water supply, a motorized metering pump, a mixing tank or a mixing section and a filter, for example one Backwash filter.
  • the volume of water flowing through the water supply is from measured a flow meter that controls the metering pump.
  • Dependent on of the volume flow are the water in the water supply via the Metering pump supplied additives, for example biocide, complexing agents and / or a hardness stabilizer to achieve a desired water quality.
  • additives for example biocide, complexing agents and / or a hardness stabilizer
  • the additional nozzles have a relatively large diameter can on a complex and expensive preparation of the treatment medium, that is Rinsing water, can be dispensed with because of the relatively large diameter Additional nozzles practically preclude the risk of the additional nozzles becoming blocked can be.
  • the treatment medium can therefore be of poorer quality than the cleaning medium and is therefore cheaper.
  • the cost of providing the treatment medium under a relatively low pressure are smaller than those for delivering the high pressure Cleaning medium. So this is only for cleaning the Conveyor belt 2 used and not - as in known cleaning devices usual- to act on propulsion nozzles to generate a rotational movement.
