Definitions

  • the invention relates to a device as it emerges from the first part of claim 1. It is based on DE-A-21 41 692, which discloses a hot-flue construction. in which the treatment medium remains in contact with the goods over a longer distance without being drawn off laterally along the edges of the web to the fan for the necessary circulation. At the same time it is achieved that with high flow energy with a compact structure this results in an overall energy-saving device.
  • the known device at the ends of the individual running loops extends over the width of the treatment chamber through suction channels, via which the treatment medium which is either supplied above or below via storage ceilings and is blown into the open running loops is suctioned off.
  • a disadvantage of this construction is, in particular, the danger that the treatment air blown into the open running loops at the top and bottom, instead of being led into the open running loops, is at least partially sucked off directly into the adjacent suction channel, i.e. without the height of the respective running loop flow through.
  • This short-circuit air flow along the edges of the web results in a flow that is too small parallel to the web surface along the running loops, so that no effective drying result can be achieved.
  • US-A-20 65 636 which describes an apparatus for the heat treatment of paper.
  • the web is repeatedly passed through an oven by being guided meander shaped manner to f arranged outside the housing pulleys.
  • the treatment medium is fed uniformly at the respective one end of the individual running loops over the width of the treatment chamber, to be precise through pipes extending inside the housing, and is also sucked off at the other end of the respective running loops via pipes arranged inside the housing.
  • the device according to DE-C-688671, in which the web deflection rollers are arranged inside the housing, is more advantageous here.
  • the treatment air is fed through pressure boxes arranged at the ends of the running loops by means of a fan and at least partially fed back to the fan at the opposite ends of the running loops through suction boxes arranged there.
  • Another part of the treatment air flows up through the open loops and is there via a further suction box arranged inside the housing. Fan fed again.
  • the air flow achieved here is also unsatisfactory, since the amount of air that can be supplied through the pressure boxes can only be small due to their construction.
  • an additional plate-like heating device is arranged parallel to the web between the pressure and suction boxes arranged in each case in order to act upon the web with radiation energy and to accelerate the blown-in treatment air by narrowing the flow area.
  • a short-circuit air flow is also avoided in this construction, however an air flow sufficient for quick and uniform drying cannot be achieved.
  • Another disadvantage is the arrangement of the fan with pipes outside the treatment housing and the complex energy supply due to the plate-shaped heating device between the suction and pressure boxes.
  • DE-A-2 508 873 discloses a hot-flue-like construction in which the treatment air is supplied from above and below by the fan to the closed fabric web loops and the air is then extracted internally after flowing through the web.
  • a suction channel is provided across the width of the web, which is closed against the directly flowing air and thus forces the air to flow along and parallel to the web loops.
  • the object of the invention is to find a hot-flue construction with which the total air power and heating energy installed in a closed and thus compact housing can be effectively heat treated with a maximum of air flow can be implemented parallel to the web, also without any edge sequences, color shifts or even uneven drying results across the web width.
  • the invention provides that essentially the entire height between the upper and lower row of rollers and in each area between an upward and downward run of a loop a the essential clear width between the runs, on the one hand blowing and on the other hand
  • Air supply box having suction openings is arranged, which is divided approximately in the middle of the height into the suction box and into a pressure box along the working width. Due to the relatively large volume of the suction and pressure box, a large amount of air can be blown into the running loops will. At the same time, due to the large volume of the air guide boxes between the running loops, there is only a narrow gap between the outer walls of the air guide boxes and the web of material passing them, but through which the supplied air must flow. Due to the narrowing of the cross-section, a high air speed is automatically achieved, which quickly removes the moisture in the goods. However, the latter feature is known from DE-A-2 508 873.
  • the pressure box is followed by an airtight nozzle box along its length, the outlet openings of which are directed at an angle of less than 90 °, preferably 45 °, against the goods in the direction of the outflowing air.
  • This measure has the effect that, in the basically small gap between the runs of the running loops and the air guide boxes, the air flows out of the nozzle boxes in the flow direction, parallel to the web. This immediately affects the parallel air flow and avoids vortices when the air jets hit the web. In this way, despite high air flow, fluttering of the material web and possibly fearing of coloring agents on the wet material web can be avoided.
  • a suction space is arranged in the device along the treatment chamber of a treatment compartment, from which the fan sucks off the treatment air flowing in from the plurality of suction channels. It is important that the fan uniformly acts on all suction boxes in a treatment compartment. To achieve this is the purpose of the suction room.
  • an air baffle also extends longitudinally through the suction space over the height of the fan intake and at a distance from the partition, which also impedes the direct action of the air flow on the directly assigned suction boxes of the running loops arranged opposite. The air must first flow around this baffle so that the suction flow in the compartments is evened out.
  • the baffle can also be omitted if the fan is not at the level of the suction boxes, but z. B. is arranged higher.
  • one embodiment of the invention provides that two groups of two rows of deflection rollers are arranged one above the other within a housing and the fan is arranged in the middle between these roller groups.
  • DE-A-16 35 356 discloses a hot-flue construction with a radial fan in the middle between two spaced rows of rollers around which the web-shaped material is guided in a meandering manner.
  • the fan blows both upwards and downwards in order to inject the treatment air via the heating units, however, into the space between the rollers into the running loop, which is open upwards or downwards, and out of the space between the rollers perpendicular to the transport direction of the web vacuum again. But it is precisely this air flow that results in the feared edge drains.
  • the device according to the invention in which basically two individual hot-flue constructions are supplied with the necessary amount of air with a fan, it is nevertheless possible to work with different temperatures. It is only necessary to subdivide the suction space at the level of the fan axis along the treatment compartment. This means that the upper part of the fan intake only sucks in the air circulated in the upper hot flue. Due to the rotation of the fan and the arrangement of the fan blades, the accelerated air emerges from the fan wheel offset by an angle, but this angle of about 30-45 ° can be taken into account by appropriate partition walls in the fan room so that an exact separation between the upper and lower air is effected. The same applies to the treatment air circulated in the lower hot flue.
  • radiators arranged at the top and bottom in the fan room with separate controllers and, if necessary, with different heating capacities, so that the quantity of web running over the upper roller group is easily treated with air of a different state than that over the lower one Roll group of running web quantity, although only a radial fan is provided to accelerate the air quantity.
  • the device consists of a heat-insulated housing 1, which is divided by a longitudinal wall 2 into a fan chamber 3 and a suction chamber 4 with a subsequent treatment chamber 5.
  • the radial fan 6 is rotatably supported horizontally, the suction pipe 7 of which opens into the suction chamber 4.
  • the suction space 4 is formed by the longitudinal wall 2, a partition 8 and with upper and lower boundary walls (here housing 1 and partition wall 17 '), the Partition 8 divides the suction chamber 4 from the treatment chamber 5.
  • two rows of deflecting rollers 9, 10 are arranged alternately on a gap, so that the web 11 to be treated can be transported in a meandering shape through the length of the device shown in FIG.
  • the z. B. serving for drying and accelerated by the fan 6 treatment air is a total of the arranged above the height of the loops between these air guide boxes 12 and also discharged into them, so that there is no air flow in the region of the deflecting rollers 9, 10 itself.
  • the fan 6 is arranged in the upper region of the housing 1 and puts the suction boxes 13 (-) of the air guide boxes 12, which are also arranged at the top, directly under negative pressure.
  • the fan 6 can also be higher, e.g. B. with an axis at the level of the rollers 9, see below.
  • the treatment air drawn in from the suction boxes 13 collects in total in the suction chamber 4 and is fed from there to the fan 6 uniformly over the width of a treatment compartment.
  • a treatment compartment comprises approximately half the length of the device according to FIG. 1, so that two fans 6 are therefore provided for this length of the device.
  • the treatment air accelerated by the fan 6 flows out downwards and is exhausted by. the heater 14 blown.
  • the pressure area (+) of the air guide boxes 12 connects to this heating device 16. It is formed by a lower wall 17, which divides the respective air guide box 12 approximately in the middle of the height into the suction box 13 and a pressure box 18 (+) lengthways. This partition wall 17 extends with the part 17 'of course also through the suction space 4 in order to completely prevent a short circuit flow.
  • the partition wall 17 between the suction and pressure box of an air guide box 12 is arranged obliquely across the width of the treatment chamber 5, namely the suction box 13 starts narrow and widens towards the fan 6, while conversely the pressure box 18 on the Inflow opening 27 begins narrowly and widens towards the end.
  • This also serves for optimal airflow and utilization of the air volume to be influenced.
  • the air guide boxes 12 are not only dimensioned so that they use the essential clear height between the upper and lower deflecting rollers 9 and 10 to a large volume of air. to be able to record, but they also take up the essential free space between the respective runs from top to bottom and vice versa of the adjacent fabric sections. For the high air flow to be generated parallel to the running direction of the web, only a narrow air gap is left, which is particularly evident from FIG. 3. This narrowing of the air flow space causes a high air speed in this drying area between the deflecting rollers 9, 10.
  • blow-out openings 22 are provided on the side walls 21 of the nozzle boxes, which are inclined by 45 ° and are now oriented upwards at an angle of approximately 45 ° to the goods 11.
  • the blow-out openings 22 are arranged on both sides of the nozzle boxes 20, so that the respective run of a material web is always acted upon on both sides by a strong air flow.
  • Baffles are provided to influence the air flow both in the pressure and in the suction part of the air side boxes 12.
  • a perforated plate 23 is arranged, which is aligned parallel to the partition wall 17 in the area of the nozzle box 20 'beginning.
  • the air openings 19 in the pressure box 18 serve to even out the air flow and to increase the static pressure.
  • a fluff filter 25 is inserted from the end wall of the housing 1 facing away from the fan 6. There, too, an additional perforated plate (25) can influence the air flow ".
  • the treatment air flowing from the suction box 13 into the suction chamber 14 initially impacts against an air baffle plate 26, which is supported on the partition wall 17 'in the suction chamber 4 at a distance from the partition 8, and at the top at the suction openings 24 Air guide box 12 ends.
  • the treatment air sucked in by the fan 6 must first flow around this upper edge of the air baffle plate 26, so that the suction boxes 13 of a treatment compartment are evenly pressurized with a vacuum.
  • Such an additional baffle 26 can be omitted if the fan 6 is not arranged exactly opposite the suction boxes 13, but higher, z. B. at the level of the deflection rollers 9. Although this creates above the rollers 9 a space enclosed by the housing wall 1, but this is favorable for the possibly necessary cleaning of the roller 9.
  • the suction space separated from the longitudinal wall 2 has an upper part 4 'and a lower part 4" with the adjoining treatment chambers 5', 5 "
  • the radial fan 6 is rotatably supported horizontally, the suction pipe 7 of which opens into the suction chambers 4 ', 4 ".
  • the suction chamber 4 ', 4 " is formed by the longitudinal wall 2 and a partition 8 with cover plates arranged at the top and bottom, the partition 8 dividing the suction chamber 4', 4" from the treatment chamber 5 ', 5 ".
  • the outlet is also arranged on the end wall on the inlet side, while on the opposite end wall of the device, the web continues inside the housing from bottom to top to the oppositely running hot flue for finishing.
  • the z. B. serving for drying and accelerated by fan 6 treatment air is a total of the respective height of the loops arranged between these arranged air guide boxes 12 ', 12 "and also discharged into these, so that in the region of the deflecting rollers 9', 9", 10th ', 10 "itself is not an air flow.
  • This has the advantage that the material web is only exposed to the air flow in its freely guided area, but does not cool it down during deflection, since the deflection rollers 9', 9", of course. 10 '. 10 "circulate within the housing 1.
  • the fan 6 is arranged in the middle of the housing 1 and puts the directly assigned upper and lower suction boxes 13 ', 13 "(-) of the air guide boxes 12', 12" directly under negative pressure.
  • the treatment air sucked in from the suction boxes 13 ′, 13 ′′ collects overall in the suction chamber 4 ′, 4 ′′, which is only divided longitudinally by a central partition wall 26, and is fed from there to the fan 6 uniformly over the width of a treatment compartment.
  • a treatment compartment comprises a plurality of rollers arranged side by side. The treatment air accelerated by the fan 6 flows both upwards and downwards and is blown through the heating devices 14 ', 14 ".
  • the regenerated air flows into the subsequent pressure range (+) of the air guide boxes 12 ', 12 ". It is formed by a partition wall 17', 17", which the respective air guide box 12 ', 12 “approximately in the middle of the height into the suction box 13', 13" (-) and Pressure box 18 ', 18 “(+) divided longitudinally.
  • This partition wall 17', 17” extends with the part “'of course also through the associated suction space 4', 4" to prevent a short sole flow.
  • the air guide boxes 12 ', 12 are not only dimensioned such that they use the essential clear height between the upper and lower deflecting rollers 9', 9" and 10 ', 10 "to be able to accommodate a large volume of air, but they also take the essential free space between the respective runs from top to bottom and vice versa of the adjacent sections of the web.
  • a narrow air gap is left, which is particularly apparent from Fig. 3 after the main application. This narrowing of the air flow space causes a high air speed in this drying area between the deflecting rollers 9 ', 9 ", 10', 10".
  • the partition 26 is arranged in the suction space at the level of the fan axis. This enables different treatment of the z. B. below wet incoming web compared to the treatment section which is now transported after drying up and requires less heating energy there, and where less moist air should be circulated. Accordingly, the heating devices should be equipped with separate controllers and, if necessary, different heating outputs. Separate air blows must also be installed for the upper and lower hot flue.
