Definitions

  • the invention relates to a shortage of hot troughs, in particular a multiple trough lack for drying and smoothing damp laundry items.
  • the mangle cylinder mostly has a perforated outer surface and a hollow bearing journal which is connected to a trigger device (DE-C-131918).
  • This exhaust air contains a significant amount of unused heat, which must be continuously applied by the heating system due to the lack of hot plates.
  • the suction line connected to the defect cylinder leads via a fan to a passage of a heat exchanger which is suitable for transferring the heat of an air stream to another.
  • the heat exchanger has a second passage through which the fresh air sucked in from the surroundings of the hot-tub shortage is pressed by means of a further fan.
  • the fresh air heated in this way is supplied to two boxes, which are arranged in front of or behind the trough and have sieve-like perforations for the fresh air to escape. In the area of these boxes, the fresh air should give off its heat to the laundry passing by and pre-dry or post-dry it.
  • the disadvantage here is that the heat exchanger is arranged separately from the ironer and at a greater distance from it. This is associated either with large heat losses during the transfer of the exhaust air from the shortage cylinder to the heat exchanger or with great expense for the heat insulation of the corresponding lines.
  • the warm air flowing into the shortage environment after contact with the laundry to be dried also means an unacceptable burden on the operating personnel due to the shortage of hot troughs.
  • the system permanently loses the amount of heat still contained in the fresh air.
  • the purpose of the invention is to reduce energy losses due to the lack of hot troughs while avoiding environmental pollution.
  • the invention has for its object to provide a hot tub shortage, which allows a more intensive use of the heat contained in the exhaust air, the heat recovery system required for this purpose should be arranged in a space-saving manner inside the hot tub shortage and should allow its subsequent expansion by additional deficiency units.
  • a very important advantage of the hot-tub ironer according to the invention is the direct assignment of a heat exchanger to each ironer unit. As a result, the heat exchanger is flowed through shortly after the exhaust air exits the ironing cylinder. The heat losses are accordingly low, and cables with a high level of insulation are almost completely eliminated.
  • the introduction of the exhaust air into an exhaust air collecting duct after the heat exchangers have flowed through enables the extraction device to be equipped with a single exhaust air fan which acts on all the existing deficiency units.
  • the flow spaces of the heat exchangers which are provided for the fresh air, are arranged in a continuous fresh air supply duct.
  • the fresh air is gradually heated as a result of passing several heat exchangers.
  • the fresh air is taken from the room, which is formed by the outer limitation of the shortage of hot plates.
  • This is preferably the interior of a side stand, which is already at a higher temperature than the area around the hot-tub shortage.
  • the intake opening of the fresh air supply duct is provided with a filter, which e.g. Retains lint and the like.
  • the fresh air conveyed by the air supply device and heated in the heat exchangers is fed to a blow-out device which is located together with the shortage cylinders and the shortage troughs in an almost closed shortage space.
  • This mangle room only has inlet and outlet openings for the items to be mangled. In this way, dry but already heated fresh air is supplied to the shortage area. This has a high drying potential without the need for additional energy.
  • the blow-out device should be arranged in the first third of the shortage area, i.e. in the zone with the highest heat demand.
  • blow-out device is designed as a nozzle box known per se from tension drying machines. This can e.g. be arranged before entering the first ironer and thus contribute to effective drying of the laundry items.
  • a hot trough shortage to which the invention relates, consists in its basic structure essentially of two side stands 1, at least one shortage cylinder 2, which is rotatably mounted in the side stands 1 and at least one shortage trough 3.
  • the shortage cylinder 2 is from the shortage trough 3 on one Central angle from 120 ° to 180 ° enclosed on the casing side.
  • each a shortage cylinder 2, a shortage trough 3, the sections of the side stand 1 assigned to them as a frame and the drive (not shown) form a shortage unit 4.
  • FIG. 1 accordingly shows a multiple trough shortage with three successive shortage units 4.
  • the shortage troughs 3 are thereby Trough bridges 5 connected.
  • the shortage troughs 3 and also the trough bridges 5 are not recognizable, these have been indicated in FIG. 1 to illustrate the structure of the hot trough shortage by dashed lines.
  • Both the mangle troughs 3 and the trough bridges 5 are heated.
  • they have heating elements which are mostly flowed through by a flowable heat transfer medium. This can e.g. Hot steam or heat transfer oil.
  • the first deficiency unit 4 is preceded by an input unit 6 known per se.
  • the lack cylinders 2 are designed as hollow cylinders and have a perforated outer surface.
  • a bearing pin of each mangle cylinder 2 is hollow and thus forms a suction opening 7 which opens into an air distribution box 8.
  • Each deficiency unit 4 is assigned a heat exchanger 9 with two flow spaces.
  • the heat exchangers 9 are preferably designed as cross-flow plate heat exchangers, so that, as can be seen in FIG. 2, a first flow space 30 consisting of a plurality of columns 10 between the plates of the heat exchanger and a second flow space 31 consisting of a plurality of columns 11 is formed.
  • the heat exchangers 9 operate according to the countercurrent or cocurrent principle.
  • the heat transfer surfaces can also be designed differently, e.g. as a glass tube heat exchanger.
  • the use of heat pipes is also advantageous.
  • the heat exchangers 9 can also, as indicated by a broken line in FIG. 1, be composed of a plurality of heat exchanger modules.
  • each heat exchanger 9 are connected on the one hand via the air distribution box 8 to the suction opening 7 of the associated mangle cylinder 2, on the other hand they open into an exhaust air collecting duct 12 which connects all existing mangle units 4 to the exhaust air fan 13 of the suction device. The latter is followed by an exhaust air duct 14 leading out of the ironing room.
  • Each deficiency unit 4 is also assigned an exhaust air quantity control device 15. This can, as for example in FIG. 2, be arranged between the heat exchanger 9 and the exhaust air collecting duct 12, but also between the suction opening 7 and the air distribution box 8 or elsewhere.
  • the flow spaces 31 of the heat exchangers 9 consisting of the columns 11 form a continuous fresh air supply duct 16 which is connected to the air supply device 17.
  • the fresh air supply duct 16 is formed only by the gaps 11 of the only available heat exchanger 9.
  • An intake line 18 leads from the fresh air supply duct 17 to the fresh air fan 19, while a pressure line 20 ends in a blow-out device 21.
  • This is be in the present example particularly advantageously designed as a nozzle box, as is well known from tension drying machines.
  • the blow-out device 21 is arranged in the first third of the almost closed lack space 25 delimited by the side stands 1, an upper cover 22, the closed surface formed by the lack troughs 3 and the trough bridges 5 and a front wall 23 and a rear wall 24.
  • This first third of the lack space 25 is the section with the greatest heat requirement in terms of the requirements of the lack process. It can be seen from FIG. 1 that the blow-out device 21 is arranged directly in front of the first mangle unit 4.
  • the blow-out device 21 can also be arranged at the end of the first mangle unit 4 and the first trough bridge 5.
  • the suction opening of the fresh air supply duct 16 is located within the outer limitation of the shortage of hot troughs, preferably within the side stand 1 which receives the heat exchangers 9, the air distribution boxes 8 and the exhaust air collecting duct 12.
  • the suction opening is advantageously provided with a filter 26, which mainly retains lint etc.
  • the rear wall 24 has an opening 27 in the vicinity of the exhaust air fan 13, which allows the entry of air from the vicinity of the hotplate shortage into the side stand 1.
  • the entire heat recovery system described above including the suction and air supply device, is arranged within the outer limitation of the shortage of hot troughs, i.e. that outside of the shortage of hot troughs there is no need to arrange any additional units for realizing heat recovery.
  • the water contained in them is evaporated.
  • the water vapor enters through the perforation of the mangle cylinder 2 into its interior and forms a water vapor-air mixture, the exhaust air 28, with the air entering through the free upper side of the mangle cylinder 2.
  • the exhaust air 28 passes through the suction openings 7 (represented by solid line arrows). into the air distribution boxes 8 and then into the column 10 of the heat exchanger 9. It finally reaches the exhaust air collecting duct 12 and is discharged by the exhaust air fan 13 via the exhaust line 14 from the shortage of hot plates.
  • the amount of exhaust air 28 to be conveyed from the lack cylinders 2 is individually influenced by the exhaust air quantity control device 15 for each lack unit 4.
  • fresh air 29 (represented by dashed-line arrows) enters the fresh air supply duct 16 from the interior of the side stand 1 through the filter 26. It is replaced by air from the vicinity of the hot tub shortage, which enters the side stand 1 through the opening 27 and thereby effectively cools the drive of the exhaust air fan 13.
  • the fresh air 29 enters an intensive, step-by-step heat transfer process with the exhaust air 28 as it flows through the fresh air supply duct 16 and is heated.
  • the exhaust air 28 gives off a considerable part of the amount of heat contained therein, which is otherwise uselessly dissipated, to the fresh air 29.
  • Trough lubricant which may be thawing from the exhaust air 28, e.g. Silicone oil collects in the air distribution boxes 8 and can be removed from them in a simple manner.
  • the heated fresh air 29 enters the deficiency space 25 from the blow-out device 21. There it meets the wet and cold laundry items entering the first ironer unit 4 and causes the drying process to be accelerated by preheating these laundry items. Irrespective of this, however, blowing the heated fresh air 29 into the shortage space 25 enables a uniformly high temperature level therein and saves a substantial amount of energy which would otherwise have to be additionally applied by the shortage troughs 3 to heat the fresh air 29.
