Definitions

  • the invention relates to a device for heat treatment one continuously in the spread state transported web, especially for drying and / or fixing a textile web, accordingly the preamble of claim 1.
  • EP-B-0 303 887 is also a heat treatment device known in the treatment air also through the upper and lower nozzle boxes on the continuously transported web is blown, whereby here too, a circulating fan the top and bottom Nozzle boxes through an F-shaped transition piece together supplied with circulating air.
  • a circulating fan the top and bottom Nozzle boxes through an F-shaped transition piece together supplied with circulating air.
  • it is in one Side wall of the fan housing one by one Bypass flap can be closed and released bypass opening provided while the inflow openings of the upper and lower nozzle boxes adjustable throttle valves assigned.
  • the invention is therefore based on the object Device according to the preamble of claim 1 in the way to further improve that during bypass operation (when the web transport is at a standstill) sufficient bypass flow from circulating treatment gas guaranteed while reducing the equipment or mechanical effort and energy consumption can be achieved.
  • a bypass valve system is assigned to the one nozzle system, while the other nozzle system with treatment gas supplying fan a drive motor with assigned frequency switch, by the this fan when the web transport is at a standstill can be reduced to minimum speed or can be switched off. If it is in this invention Treatment device to a standstill of the web transport comes, then one can Fan (for the upper nozzle system or for the lower one Nozzle system) with the help of the frequency switch reduced a minimum speed or switched off completely be so that then by this fan only a very small, harmless amount of treatment gas circulated via the associated nozzle system or the treatment gas flow for this nozzle system is completely switched off becomes.
  • the other fan can largely continue to work unchanged because of him generated treatment gas flow through the associated bypass valve system around or on the web directed past and directly to the treatment gas supply system is recirculated, thereby providing for the Heating device remain unchanged in their setting can, so when restarting the web transport and thus the treatment gas for the entire heat treatment largely without delay to the same Temperature as set before standstill.
  • This training according to the invention essentially requires only one bypass flap (for one nozzle system) to be provided (with a correspondingly low mechanical effort).
  • bypass valve system either the upper nozzle system or the lower nozzle system assign to the heating circuit of the treatment gas flows maintain. Particularly useful it is, however, if the bypass valve system matches the bottom Nozzle system and that through the frequency switch controllable first fan assigned to the upper nozzle system is. In this way, the heating circuit maintaining gas flow path is relatively short being held.
  • the drawing shows a preferred embodiment of the heat treatment device according to the invention, namely in the version as a stretching machine for drying and / or fixing a textile web WB.
  • the Tensioner contains a largely in the usual way closed device or machine housing 1, in at least one treatment field F is formed; however, as can be seen in FIG. 2, in the direction of web transport (according to arrow 2 in Fig. 2) several immediately successive treatment fields F provided.
  • Above and below the - in Fig.1 defined by the web WB itself - Goods web transport level are upper and lower nozzle systems for inflating treatment gas onto the associated arranged upper and lower web pages.
  • each Treatment area F the upper nozzle system by a upper nozzle box group 3 and the lower nozzle system formed by a lower nozzle box group 4, wherein this across the treatment range of the stenter reaching nozzle box groups each by a number of individual nozzle boxes in a manner known per se are trained.
  • During heat treatment operation can in a conventional manner treatment gas on the Top and bottom sides of the web WB are inflated, as indicated by arrows in Fig.1.
  • the Material web is spread out during this heat treatment or wide-spread condition continuously accordingly the arrow 2 in the longitudinal direction through the tensioning machine transported through, for this web transport - as is common in tensioners - endlessly revolving in the area of each length of the web and correspondingly drivable tension chains 6 are provided are.
  • two fans 7, 8 provided by which the pressure side 7a of the first fan 7 over a first gas supply channel 9 with the inflow opening 3a the upper nozzle box group 3 and the pressure side 8a of the second fan 8 via a second gas supply channel 10 with the inflow opening 4a of the lower nozzle box group 4 is connected.
  • a common treatment gas supply system provided one with the suction sides 7b and 8b of both fans 7, 8 connected Gas intake duct 11, a filter device 12 for Separation of impurities (fibers, lint and the like) from the recirculated air as well as a heating device 13 for heating or reheating the circulating air in front of the fans 7, 8 contains.
  • the Gas intake duct 11 approximately across the tensioning machine or transversely to the direction of web transport (arrow 2), where this gas intake duct 11 through a corresponding transition piece 11a to the suction sides 7b, 8b of the two Fans 7, 8 is connected.
  • the Bypass valve system for the lower nozzle box group 4 can be relatively simple in terms of equipment or mechanics be trained. It contains a bypass valve 15, which in the present embodiment in which the Pressure side 8a of the second fan 8 with the inflow opening 4a connecting the lower nozzle box group 4 Gas supply channel 9 is arranged.
  • This bypass valve 15 can with the help of one indicated in Fig.1 Linkage (adjusting device) 16 between a Open position - as shown in Fig.1 is - in the inflow opening 4a to the lower Nozzle box group 4 is released, and one - in Fig. 1 only indicated by dashed lines - bypass position be adjusted in which the inflow opening 4a is closed, so the flow connection between the second gas supply channel 10 and the lower nozzle box group 4 shut off and thus that of the second fan 8 incoming circulating air directly into a gas recirculation room 19 deflectable within the machine housing 1 is.
  • Fig.1 Linkage (adjusting device) 16 between a Open position - as shown in Fig.1 is - in the inflow opening 4a to the lower Nozzle box group 4 is released, and one - in Fig. 1 only indicated by dashed lines - bypass position be adjusted in which the inflow opening 4a is closed, so the flow connection between the second gas supply channel 10 and the lower nozzle box group 4 shut off and thus that of the second
  • the drive motor 8c of the second fan 8 of each treatment field F also to provide a frequency converter in such a way that thereby a general quantity regulation of this second fan 8 generated treatment gas flow / circulating air flow can be generated.
  • the relatively inexpensive frequency switch these days for the drive motors 7c, 8c of both fans 7, 8 of each treatment field F can thus be energy-saving Way a very precise air volume control made for the upper and lower nozzle box groups 3, 4 be without mechanically complex Throttle valves (with actuators etc.) are provided Need to become.
  • a control device 17 is provided in each treatment field F - as indicated by thin lines - on the one hand, at least with the web transport device, thus with the tension chains 6 (or with their drive device) in signal connection and to the other with the frequency switch 14 for the drive motor 7c of the first fan 7 and with a flap actuator 18 is in switching connection, via the linkage 16 is connected to the bypass valve 15.
  • This control device 17 is designed such that with a standstill signal from the tension chains 6 via the frequency switch 14, the speed of the first Fan 7 to a minimum value or to zero regulated down or the drive motor 7c of this first Fan 7 can be turned off while at the same time the bypass valve 15 via the valve actuator 18 adjusted in their bypass position mentioned above becomes.
  • the control device 17 receives a corresponding signal, so that then via the frequency switch 14 the first fan 7 to its optimal Operating speed regulated and at the same time the bypass flap 15 on the flap 18 in their top explained opening position is reset.
  • the control and switching measures described above apply of course equally for all treatment fields F of the tensioner but only one Control device 17 is required.
  • the heating device 13 can be used for the circulating air flows generated by both fans 7, 8 common heating device in any suitable Formed in the treatment gas supply system and be arranged.
  • the one illustrated in the drawing Embodiment is preferred the heating device by a direct heating, with gas or light fuel-operated burner device 13 form, which is useful on the fans 7, 8th opposite housing longitudinal wall 1b and at least partially arranged within the filter device 12 is and directly via a suction nozzle 11b in the open ends directed towards this longitudinal housing wall 1b of the gas intake duct 11 works.
  • the common heating device for both fans 7, 8 of each treatment field F could, if necessary also - in a manner known per se - by one in the area the gas intake duct 11 arranged and from recycled treatment gas flowed through indirect Heat exchanger be formed.
