Definitions

  • the invention relates to a mangle trough for a trough mangle equipped with at least one mangle roller, in particular mangle trough for large trough mangles, with a trough plate designed as a half-shell with a mangle surface facing the mangle roller and with a heatable outer surface.
  • Shortage troughs of this type are known for flat ironing ironers with a larger shortage roller diameter. Material with a thickness of approximately 15 to 20 mm is used for the trough plates of these known constructions. Individual heating dishes are arranged on the outer contour of the trough plate, which overlap like scales and are formed by curved sheet metal strips.
  • This object is achieved in that at a distance from the outer surface of the trough plate is designed as a half-shell jacket, which essentially covers the outer surface of the trough plate and is firmly connected to this outer surface on all sides, that the double jacket thus formed connections for the supply and discharge of Has heating medium and that guide webs for the heating medium run in the double jacket.
  • These measures give the mangle trough such a high degree of internal rigidity that it is possible to significantly reduce the material thickness of the trough plate from usually 15 to 20 mm.
  • the heat transfer from the heated outer surface to the inner surface of the mangle trough facing the mangle roller is considerably improved, which leads to significant energy savings with respect to the heating medium.
  • the guide webs are firmly connected to the outer surface of the trough plate and that the jacket plate bears tightly against the guide webs.
  • This has the advantage that the guide bars only have to be attached to the outer surface of the trough plate by tack welding. Long and precise weld seams of high quality as with the well-known heating shell construction common, can be avoided.
  • the jacket plate is merely provided with a weld seam along its outer circumference, which firmly connects the trough plate, the head plates and the jacket plate.
  • the jacket sheet fits tightly against the guide bars without being fastened with them.
  • the guide webs run longitudinally to the trough axis and are arranged at approximately the same radial distance from one another on the outer surface of the trough plate, so that the heating medium introduced into the double jacket heats sectoral surfaces along the trough axis, which results in a more uniform Heat exposure of the ironer leads.
  • heating chambers are formed in the double jacket, which are interconnected with at least one flow opening for the heating medium.
  • At least one supply line for the heating medium is guided approximately centrally into the radially outer heating chambers, so that the heating medium can be divided approximately equally between the two halves of the shortage trough.
  • the flow openings connecting the heating chambers - seen in the longitudinal direction of the trough axis and starting with the radially outer heating chambers - are arranged in the region of the chamber front sides and that the flow openings of the directly adjacent heating chambers are arranged in the central region of the chamber longitudinal side and that in this alternating sequence the flow openings connect the subsequent heating chambers.
  • the heating medium introduced into the double jacket is thus first divided into the two halves of the mangle trough in the outer heating chamber, merged and mixed in the following and adjacent heating chamber, divided in half again in the subsequent chamber next, etc., so that this can be seen through this hot steam duct extremely uniform heating of the inner surface of the mangle trough is achieved within the double jacket.
  • the heating chamber arranged in the region of the trough sole is connected to the heating chambers adjacent on both sides via flow openings which are arranged in the end region of these chambers.
  • the heating chamber arranged in the region of the trough sole is connected via passage openings to a collecting pan for the condensate of the superheated steam as the heating medium. The same applies to all other heating media.
  • rib-shaped reinforcing elements are arranged at a distance from one another, the inner contour of which is adapted to the outer contour of the double jacket, which makes a very torsionally rigid construction is guaranteed for the mangle trough.
  • the mangle trough 1 consists of a trough plate 2 formed into a half-shell with a thickness of approximately 15 mm, with a milled and polished mangle surface 3 facing the mangle roller, not shown, and with an outer surface 4.
  • a jacket plate 5 arranged, which almost covers the outer surface 4 of the trough plate 2 and is firmly connected to it, with the aid of continuous weld seams 6.
  • the double jacket 7 formed in this way has two feed connections 8, 9 for a heating medium and in the region of the trough sole 10 a collecting tray 11 for the discharge of the condensate or the heating medium with the aid of a discharge line 12.
  • guide webs 13 arranged for the heating medium.
  • the guide webs 13 are fastened to the outer surface 4 of the trough plate 2 by tack welding.
  • the jacket plate 5 is supported on the outer edges 14 of the guide webs 13 in such a way that a pressure-tight contact is established at this connection point between the guide web 13 and the jacket plate 5.
  • the curvature of the cladding sheet 5 therefore largely corresponds to the curvature of the trough sheet 2.
  • a supply line 15 is laid, which in turn has a connecting flange 16 for connection to an energy supply line, not shown.
  • the discharge line 12 opening out of the collecting tray 11 likewise has a flange 11 for the purpose of connection to a collecting line, not shown.
  • rib-shaped reinforcing elements 20 are arranged on the double jacket 7 or on the outer jacket plate 5, which are spaced apart and whose inner contour is adapted to the outer contour of the double jacket 7 is.
  • FIG. 2 it can be seen that with the help of the guide webs 13 in the double jacket 7 heating chambers 21, 22, 23, 24 are formed, which are connected to each other with flow openings 25, 26 for the heating medium.
  • the individual heating chambers likewise extend in the direction of the trough axis 19.
  • the flow opening 25 connecting the heating chamber 21 to the heating chamber 22 is arranged on the end face 27 of the chamber; the flow opening 26 connecting the heating chamber 22 and the heating chamber 23 is arranged in the central region 28 of the longitudinal side 29 of the chamber.
  • the heating chamber 24 arranged in the region of the trough sole 10 is connected to the two adjacent heating chambers 23 via flow openings 25, which are located are again in the chamber end region 27.
  • the elongated collecting bowl 11 can be seen, which is connected to the heating chamber 24 via passage openings 30.
  • the condensate or heating medium accumulated in the heating chamber 24 enters the collecting tray 11 via these through openings and flows through the discharge line 12 into the collecting line, not shown in any more detail.
  • the reinforcement elements 20 are arranged at a distance from one another, which extend at right angles to the guide webs 13 running parallel to the trough axis 19.
  • the heating trough 1 is heated in such a way that the heating medium with the appropriate temperature and operating pressure is fed via the feed line 15 to the two feed connections 8, 9 and approximately in the central region 28 of the longitudinal chamber side 29 into the radially outer heating chamber 21 occurs.
  • the heating medium flows on both sides to the front side of the chamber and there it enters the adjacent heating chamber 22 through the flow openings 25.
  • the heating medium then flows from the outside to the center of the chamber. The portions of the heating medium are combined and flow through the flow opening 27 into the next adjacent heating chamber 23 and divide up again in this heating chamber.
  • the partial quantities of the heating medium flow from the central region to the chamber end face 27 and enter through the flow openings 25 therein Heating chamber 24, which is arranged on the trough sole 10.
  • the condensate or heating medium collects in this heating chamber 24 after the heating medium has given off its heat to the trough plate 2.
