Definitions

  • the invention relates to a device for cleaning a conveyor belt of a papermaking machine, for example a dry or wet sieve belt or a felt belt, with at least one nozzle which can be directed against the conveyor belt for loading the conveyor belt with air or liquid.
  • conveyor belts in particular fabric belts, are used in paper machines. These conveyor belts become contaminated during the operation of the paper machine; Meshes or pores of these tapes are added, for example, from paper fibers, adhesives or other additives. In order to ensure the proper functioning of the conveyor belt, especially in the dryer section of the paper machine, the conveyor belt must be cleaned.
  • a cleaning device of the type mentioned at the outset which is usable for this purpose is known from G 92 08 909.7 U1.
  • the conveyor belt is acted upon by deflection liquid after deflection by 180 ° from above and from the side opposite the transport side.
  • the rotatable nozzles are arranged in the area of the loop guide of the endless conveyor belt.
  • collecting troughs are provided below the conveyor belt for receiving and removing cleaning fluid and detached contaminants.
  • splash water or dirty water is formed as a result of the liquid jet emerging from the rotating spray nozzle at high pressure and hitting the conveyor belt. It also proves to be disadvantageous that water remains in the fabric of the conveyor belt, which leads to the rewetting of the paper web that comes into contact with the rotating conveyor belt a little later. This can be particularly the case with paper webs with basis weights of less than 50 g / m 2 lead to disruptions in the production process.
  • the invention is therefore based on the object of improving a cleaning device of the type mentioned at the outset in such a way that the disadvantages mentioned do not occur, that the device is compact and, in particular, can be produced economically and can be used reliably.
  • This object is achieved in that a suction chamber directly surrounding the cleaning nozzle is provided, so that dirt and / or water mist or residual water detached from the conveyor belt by the nozzle jet can be sucked in and removed in the shortest possible way into the suction chamber.
  • the suction space is formed by a suction bell surrounding the cleaning nozzle in the form of a jacket. In this way, a compact and integral design of a combined nozzle and suction device is achieved.
  • the suction bell can preferably be formed by an essentially cylindrical casing of the cleaning nozzle which, as is known per se, traverses across the conveyor belt. Instead of a casing with a circular cross section, an elliptical or oval shape can also be provided.
  • the cleaning nozzle or the nozzle head can be arranged eccentrically to the sheathing in the opposite direction of the belt.
  • the suction bell is designed to widen, in particular bell-shaped or conical, at its end region facing the conveyor belt. As a result, the surface area of the conveyor belt, which is captured by the suction bell or by the suction space, is enlarged.
  • the cleaning nozzle is inclined with respect to the surface normal of the conveyor belt.
  • at least one rotating and inclined cleaning nozzle is preferably provided, since this allows the nozzle jet to better detach the dirt adhering to the conveyor belt. Because the nozzle rotation provides a cleaning impulse that hits the conveyor belt from different directions. It has been shown that the cleaning effect is most effective in the area of rotation in which the cleaning nozzle or the nozzle jet has a speed component opposite to the running direction of the conveyor belt.
  • the opening of the suction bell facing the conveyor belt is designed to be adapted to the surface profile of the conveyor belt or the cylindrical shape of a roller over which the conveyor belt is guided.
  • FIG. 1 shows an embodiment of the cleaning device 2, which is arranged in the region of a roller 6 of a paper machine, not shown, for cleaning a dryer fabric belt, hereinafter referred to as dryer fabric 4.
  • the cleaning device 2 can be used for any conveyor belts in a paper or cardboard manufacturing machine, for example for wire belts or felts in a wire or press or dryer section of a paper machine. In the following, dry sieve belts of a paper machine are assumed purely by way of example.
  • the cleaning device 2 comprises a rotor nozzle, hereinafter referred to as cleaning nozzle 8, with a rotatable nozzle head 10, which has a nozzle arrangement (not shown).
  • This nozzle arrangement can comprise one or more tangentially flowing driving nozzles for generating a rotational movement in the range from 2000 to 3000 revolutions per minute, as well as one or more cleaning nozzles which apply a cleaning medium to the dryer fabric 4.
  • a cylindrical suction bell 14 is provided, which surrounds the cleaning nozzle 8 and the nozzle head 10.
  • the interior of the suction bell 14 is connected in terms of flow to a suction line 16, and forms a suction space 18 assigned to the cleaning nozzle 8.
  • the cleaning device 2 comprises an energy chain for the media supply, of which only one high-pressure hose 20 connectable to a high-pressure pump for supplying the cleaning nozzle 8 with liquid in a pressure range from 100 bar to 1000 bar, preferably from 100 bar to 400 bar, in particular from 150 bar to 300 bar and the suction line 16 for discharging splash water or water mist with dirt particles present therein from the suction chamber 18 is shown.
  • the previously described device components of the cleaning device 2 are arranged displaceably on a traversing carriage 11 in a direction transverse to the running direction of the dryer fabric 4.
  • the traversing carriage 11 sits on cross members 12 and can be driven by a traversing motor, not shown, at a predeterminable speed, the traversing speed usually being in the range of 0.3 m / min.
  • an end region 22 of the suction bell 14 facing the drying wire 4 is adapted to the circular cylindrical circumferential shape of the roller 6, so that a certain adjustable distance or gap is ensured between the suction bell 14 and the drying wire 4, which along the Edge 24 of the end region 22 is substantially constant.
  • the arrangement of the cleaning device in the area of the roller 6 has the following advantage: the meshes of the transport screen 4 are due to the deflection the roller expanded, so that the cleaning medium can penetrate particularly easily into the fabric formation of the transport screen and remove impurities very effectively.
  • the cleaning nozzle 8 or the nozzle arrangement in the nozzle head 10 is acted upon by a cleaning medium, preferably with water under high pressure, via the high-pressure hose 20.
  • the nozzle head 10 with the arrangement of individual nozzles is set in rotation by the recoil effect of the driving nozzles.
  • the liquid jet describes a conical path 27 running at a certain angle to the longitudinal axis 26 of the cleaning nozzle. It thus strikes the drying screen 4 at an angle and thus removes the contaminants from its surface.
  • nozzle head 10 It is also possible to equip the nozzle head 10 with one or more pivotably mounted individual nozzles which carry out an oscillating movement and which sweep over a band-shaped region of the drying wire 4 during the traversing movement of the nozzle head 10.
  • the dirt particles are hit by the liquid jet of the nozzle arrangement in different directions and can thus be detached more easily than when using a nozzle running parallel to the central axis 26.
  • the inclination of the nozzle head 10 or the nozzle arrangement also has the effect that the liquid jet striking the dryer fabric belt enters the suction chamber 18 is reflected so that the resulting water mist with dirt particles bound therein and residual water can be removed via the suction line 16.
  • FIGS. 2 and 3 show a nozzle head 10 ′ corresponding to the rotatable nozzle head 10 in different views.
  • the nozzle head 10 ' is rotatably held on a flange 30 by means of a bearing 28.
  • a stationary nozzle feed line 32 is provided, which opens into a pressure chamber 34, the walls 36 of which bear sealingly against the inside of a cylindrical component 38.
  • the cylindrical component 38 has four openings arranged at an angle of 90 ° to one another.
  • nozzle feed lines 40 Connected to this are nozzle feed lines 40 which extend radially outwards and are bent in their end section by preferably 90 °, as can be clearly seen in FIG. 5.
  • the nozzle feed lines 40 finally end in inclined cleaning nozzle end regions 42.
  • the driving nozzles also provided are not shown. How to 2 and 3 can also be seen, only one of the nozzle feed lines 40 is always pressurized, while the other nozzle feed lines 40 are depressurized.
  • the pressure chamber 34 is now oriented so that the liquid jet has a speed component opposite to the direction of travel of the drying wire 4, so that the cleaning effect is particularly high.
  • the nozzles, the liquid jet of which would have a speed component in the running direction of the dryer fabric 4 are depressurized and therefore deactivated in order to reduce water consumption.
  • the cleaning nozzle 8 or the individual nozzles in the nozzle head 10 are designed for a pressure range from 100 bar to 1000 bar, preferably from 100 bar to 400 bar, and have a nozzle diameter from 0.1 to 0.8 mm, preferably from 0.2 mm to 0.4 mm. Pressure values from 150 bar to 300 bar and nozzle diameters from 0.2 mm to 0.4 mm have proven particularly useful. Diamond or ruby, preferably sapphire or ceramic materials, are used as the nozzle material.
  • FIGS. A second exemplary embodiment of a cleaning device is shown schematically in FIGS. This corresponds essentially to the cleaning device described with reference to FIGS. 1 to 3, which is why a repeated explanation of the matching parts is dispensed with.
  • One difference is the oval cross-sectional shape of the suction bell 14, in which the nozzle head 10 is arranged eccentrically in the opposite direction of the belt running (arrow P). This improves the suction effect on the water mist (loaded with dirt).
  • a screen 61 is provided between the nozzle head 10 and the dryer fabric 4, the outermost edge 63 of which is angled.
  • This edge 63 serves as a fastening edge for webs 65, which in turn are connected to the inner wall of the suction bell 14. Openings or gaps 67 are formed between the individual webs 65, the suction cup wall 14 and the panel edge 63, via which a connection from the suction chamber 18 to the outside is created.
  • the aperture 61 has an opening 69, which is located in the effective area of the rotating nozzles 71.
  • the dimensioning and position of this opening 69, in particular in the circumferential direction of the diaphragm 61, is selected such that at least one nozzle 71 always passes through this area, the direction of the nozzle jet here being opposite to the direction of tape travel indicated by the arrow P.
  • the liquid mist reflected by the drying wire 4 is sucked into the suction chamber 18 either through the aperture 69 or through the aforementioned gap 67.
  • the nozzle head 10 is driven via drive nozzles 73. It can be seen from FIG. 4 that these drive nozzles 73 are oriented in such a way that the outflowing medium has an axial flow component which corresponds to the axial component of the liquid jet emerging from the nozzles 71 is opposite. This can compensate for the axial recoil forces, which leads to a relief of the bearing 28.
  • FIG. 6 shows a further exemplary embodiment of a cleaning device, in which, however, no rotating cleaning nozzles are provided. Rather, the cleaning nozzles 81 are firmly connected to the suction bell 14.
  • the cleaning nozzles 81 are oriented toward the center of the suction bell 14 in such a way that the liquid jets 83 preferably meet at a point which lies opposite the opening area of the suction bell 14. If this point lies directly on the conveyor belt or the dryer fabric, a point-like loading is achieved. The distance between the nozzles and the dryer fabric changed, the intersection of the liquid jets also shifts. The point-like application then becomes an area-like application.
  • the liquid mist bouncing off the drying wire 4 is sucked into the suction chamber 18, as in the previous cases.
  • the suction effect is enhanced by the suction bell, which continues underneath the nozzles 81 and ends only very close to the dryer fabric. Air flows through the gap 85 formed between the suction bell 14 and the drying sieve 4 and carries the liquid mist with it.
  • the cleaning nozzles 81 are aligned such that the component directed in the direction of movement of the drying wire 4 is as small as possible.
  • a section of a dryer section is shown schematically in FIG. 7, two single-row dryer groups 91 and 93 being indicated.
  • Each of these two dryer groups 91 and 93 is composed in a known manner from several drying cylinders 95 and deflection rollers 97. Drying cylinder 95 and deflecting rollers 97 are arranged so that the paper web is alternately guided over the drying cylinders and deflecting rollers and the drying group passes through in a meandering manner.
  • Each dryer group 91 and 93 is assigned a dryer fabric 4, which opens at the beginning of each dryer group the paper web runs up and is removed and returned at the end of the drying group.
  • a cleaning device 2 interacts with a dryer 4.
  • the two cleaning devices 2 are each arranged on a dryer fabric guide roller 6 in the initial region of the return of the dryer fabric 4. It can thus be achieved that the cleaning liquid remaining on the drying wire 4 can evaporate before the drying wire comes into contact with the paper web again.
  • An exemplary embodiment of a drying group is particularly preferred, in which the cleaning device 2 is arranged in one of the first, preferably the first drying wire guide roller 6, which is provided after the last drying cylinder 95 of a drying group 3. Characterized in that a cleaning process is initiated immediately after the removal of the drying wire 4 from the drying cylinders 95, there remains a relatively long time until the drying wire 4 runs back to the beginning of the drying group and comes into contact with the material web again. Such an arrangement of the cleaning device thus reliably prevents rewetting of the material web.
  • the guide rollers of the return line following the roller 6 also contribute to the removal of liquid from the drying wire 4, firstly by the overpressure in the overflow gussets or in the incoming nips and secondly by the centrifugal force exerted on the liquid particles when running around the roller.
  • the excess pressure in the incoming nip can also be used to improve the effect of the cleaning device 2.
  • the cleaning device is arranged in the area of the incoming nip, as can be seen in the left-hand cleaning device shown in FIG. 7 or as explained in more detail with reference to FIG. 8.
  • the air entrained by the transport screen 4 is caught between the top of the transport screen 4 facing the roller 6 and the surface of the roller 6. This creates an overpressure in the incoming nip N, which causes an air flow through the porous transport screen 4.
  • the air penetrating the transport screen 4 tears dirt particles detached from the cleaning device 2 into the suction area of the suction bell 14, thus supporting the suction effect of this bell and thus the cleaning action.
  • the cleaning device 2 is preferably arranged so that the cleaning medium strikes an area of the transport screen 4 which is arranged very close to the surface of the deflecting roller. This ensures that the transport screen deforms very little when the cleaning medium strikes it, so that the energy lost is very low. With such an arrangement of the cleaning device, it remains ensured that the excess pressure in the area of the incoming nip N supports the suction effect of the suction space and leads to particles detached from the surface of the transport sieve are discharged, with at most very little cleaning medium emerging from the suction space.
  • the cleaning device 2 can also have a scraper device 101, which - viewed in the direction of movement of the drying wire 4 - is arranged downstream of the cleaning nozzles 8 and interacts with the surface of a wire guide roller 103 which deflects the drying wire 4.
  • the scraper device 101 is arranged such that, as can be seen in more detail in FIG. 9, dirt particles are removed from the surface of the screen guide roller 103 by means of a scraper 105 and then fall into a collecting trough 107.
  • the dirt particles on the surface of the wire guide roller 103 are those particles which, although detached from the nozzle head 10, have not yet been finally removed and which were then moved further to the wire guide roller 103 with the dryer wire 4.
  • the cleaning staff can be built up using both gaseous and liquid media. It is also conceivable to use laser and ultrasound sources to remove contaminants from the belt surface.
  • the application of the cleaning device is selected depending on the material of the conveyor belt and the adhering particles. As a rule, liquid is continuously released to the nozzle head. However, it is also conceivable to build up a discontinuous, for example pulsating, flow of a cleaning medium in the case of corresponding surfaces or soiling in order to clean the belt surface.
  • the direction of impact of the cleaning medium is crucial for cleaning the conveyor belt surface.
  • a change of direction of the cleaning flow is also very advantageous for loosening dirt particles. This can be achieved with the help of oscillating nozzles. It is important that this cleaning effect can also take place without traversing the cleaning device, if necessary.
  • a plurality of cleaning or nozzle heads distributed over the width of the transport path to be cleaned are arranged, each of which is provided with at least one or more individual nozzles.
  • the cleaning effect varies by changing the distance between the nozzle and the conveyor belt surface, changing the pressure of the cleaning agent and / or changing the nozzle cross-section and can be adapted to different types of contamination and conveyor belt surfaces.
