Definitions

  • Articles made of fabric are chemically cleaned by placing the items in a treatment room, e.g. a rotating drum, first washed with a dirt-dissolving solvent, which is circulated and filtered in a dirt filter device outside the treatment room, after which the solvent supply is interrupted, the solvent is allowed to flow out of the treatment room and the objects are thrown and then thrown into exposes a second circuit flowing hot air flow, which dries the objects and evaporates the solvent still adhering, which is removed from the warm air flow by condensation.
  • the dirt filter device is cleaned from time to time or its filter is replaced.
  • the invention relates to a cleaning system for carrying out this method, that is, to a cleaning system for the chemical cleaning of objects made of fabric, for example clothes, with a treatment room formed, for example, by a rotatable drum, which is connected to a solvent circuit and to a hot air circuit to be operated according to this is, in each of which a conveyor is connected and of which the solvent circuit is a dirt filter device contains, while in the warm air circuit an air cooler with a condensate separator and an air heater downstream of the air cooler are included.
  • a first air line branches off from the warm air circuit after the air heater and is connected to the input side of the filter device and that a second air line leads back to the warm air circuit from the output side of the filter device.
  • the system shown in Fig. 1 is used for chemical cleaning of objects made of fabric, such as clothes, curtains, etc.
  • a cleaning drum 2 is included, which is rotatably mounted on the housing 1 and in the treatment room 3 enclosed by it, the objects to be cleaned can be entered.
  • these objects are washed with a solvent that removes the dirt.
  • the treatment room 3 is connected to a solvent circuit 4 at G.
  • This comprises a solvent container 5, from which the solvent is removed by means of a conveyor 7 in the form of a pump via a line section 6.
  • the solvent reaches a filter device 8 with a filter 9 via the line section 10 arranged upstream of the filter device 8.
  • the solvent enters the filter device at the inlet side and flows through the filter 9, on which the solvent is located Dirt settles, and leaves the filter device on the outlet side, from where it reaches the drum 2 via a line section 11 of the solvent circuit upstream of the filter device, to the drum 2 in the treatment chamber 3 of which the solvent is introduced in the axial direction.
  • the solvent then flows out of the drum housing 1 via the lower outlet 12 and returns to the storage container 5 via a lint filter 13.
  • the supply of solvent to the treatment room 3 is interrupted, the washed objects are spun in the drum, and the spun-off solvent is left drain into the reservoir 5.
  • the solvent also flows back out of the filter device 8 into the container 5, which can take place via the line section 10 or the line section 11, depending on the special arrangement of the solvent circuit.
  • the treatment room 3 is connected to a further circuit, namely to a warm air circuit which flows around the drum 2 and a drum housing attachment 14. After washing and spinning, the objects in the drum are exposed to this warm air stream for drying, and the solvent still adhering is also evaporated.
  • the hot air flow emerges from the treatment room 3 at an upper radial outlet 15 of the drum housing 1, flows through a further lint filter 16 and passes through an air cooler 17, an air heater 18 connected downstream of the air cooler in the flow direction, and via an upper radial inlet 19 into the treatment room 3 back.
  • a codensate separator (not shown) is assigned to the air cooler 17, in which the solvent which condenses at this point is separated from the hot air stream, so that the air subsequently heated in the air heater 18 frees from the solvent and re-enters the treatment room 3.
  • the warm air flow is maintained by a second conveyor, which is arranged in the housing extension 14 between the lint filter 16 and the air cooler 17 and of which only the motor 2o is shown.
  • the dried objects in the drum 2 are still ventilated with circulating air or fresh air.
  • the drum housing has a fresh air flap 21, indicated by dashed lines, which is opened after the drying process.
  • the conveyor 2o of the warm air circuit remains switched on, so that the fresh air flowing into the treatment room from the surroundings reaches the housing extension 14 via the outlet 15.
  • the circulating air or fresh air flows through the lint filter 16 and the air cooler 17, so that, in turn, any residues of the solvent that may have been carried along are removed by condensation.
  • the air cleaned in this way is then blown off to the outside via an outlet flap 22 between the air cooler 17 and the air heater 18. It goes without saying that the flap 22, like the flap 21, is closed in the preceding method steps.
  • the dirt filter device 8 must be cleaned from time to time or the filter 9 contained in it must be replaced.
  • the dirt accumulated here is soaked with solvent after the washing process, so that for reasons of environmental protection the filter 9 cannot simply be thrown away or cleaned, for example, by rinsing. Without additional measures, the dirt provides one. Waste, for the disposal of which legal regulations must be observed.
  • a part of the hot air flow mentioned can flow through the filter device 8 in the course of a cleaning process after washing while the objects are being dried and the solvent evaporates from the treatment room 3, so that this flows in this or in Collected dirt evaporates solvent 'and is carried away by the hot air flow.
  • the named part of the hot air flow is branched off to the filter device 8 after the condensation point, that is to say after the air cooler 17.
  • the branch point is also arranged after the air heater 18 of the warm air circuit, so that into the filter direction cleaned hot air enters.
  • An air line 25 is used for this purpose, which is connected from the housing extension 14 to the input side of the filter device 8. This air line 25 can be switched off and remains closed during the washing process.
  • a valve 26 serves this purpose.
  • a second air line leads back to the hot air circuit, specifically into the treatment room 3.
  • this second air line is formed by the line section 11 of the solvent circuit, which lies downstream of the filter device 8 and connects it to the treatment room 3, so that the latter Line section 11 fulfills a double function.
  • the circulating air connections formed by the flaps 21, 22, 27 can be operated simultaneously within the program sequence of the cleaning process. It goes without saying that the actuation of the valve 26 and the actuation of the two shut-off valves 28, 29 shown in the solvent circuit as well as any other valves or organs controlling the process sequence are not actuated manually, but automatically.
  • FIGS. 2 and 3 show a special embodiment of the filter device 8 in two different operating positions.
  • This filter device has a filter housing 3o into which the first air line 25, the line section 11 of the solvent circuit forming the second air line and downstream of the filter device 8 and the line section 10 of the solvent circuit lying upstream of the filter device 8 open out. 2, only the opening of the first air line 25 into the filter container is visible, which is located on the rear side of the housing 30 below the plane of the drawing.
  • the line section 10 of the solvent circuit is divided into two partial sections 10a, 10b, these two hoses or tubes unite to the conveying device 7 and run in the area of the filter device 8 on both sides of the centrally arranged line section 11.
  • the filter 9, which has a flat shape at right angles to the vertical filter plane and can be formed by a paper filter, is arranged at the funnel-shaped muzzle end 31 of the downstream processing section 11 of the solvent circuit.
  • the mouths of the line sections 10,11 are located on the same side of the housing 3 0, namely in the embodiment of the case bottom 32, where they are arranged at a fixed distance from each other.
  • the mouths of the two line sections 10, 11 can be connected to and separated from one another by means of an actuating device 33 which can be actuated from the outside, in the exemplary embodiment being associated with a connecting device 34 which is seated on the actuating device 33 and which between a position connecting the orifices (FIG. 2) and a position separating the orifices (FIG.
  • the e.g. plate-shaped yilter 9 rests on a filter grate 4o, which in turn rests on the wall of the mouth region of the line section 11.
  • the filter 9 is more central.
  • Tail 37 of the connecting device 34, which forms a type of cover, is fixed, which sits on the edge of the filter 9 and is pressed against it.
  • ⁇ flat filter '' is also to be understood to mean a filter folded, for example, in a zigzag shape, the main extension of which, however, extends in one plane, expediently in the horizontal.
  • the actuating device 33 is formed by a rod or the like. which penetrates the opposite side of the housing 30 and is resiliently connected to the connecting device 34 by means of a spring 41.
  • Lie connecting device 34 is by means of the rod 33 or the like resiliently pressed against the mouths of the line sections 10, 11.
  • the actuating device formed can be actuated pneumatically from the outside, the adjustment of the actuating device in order to transfer the connecting device either to the position according to FIG. 2 or to that of FIG. 3 can be integrated into the program sequence of the system.
  • the deflection flap 27, the function of which has already been described above, is also articulated on the filter housing 3o. Instead of a flap or a controlled by a valve air recirculation or the like. to be available.
  • the solvent can run off well after the solvent circuit has been switched off.
  • the air line 25 is connected to the line section 11 within the filter housing 3o and the hot air can flow through the filter insert 9 and the adhering dirt.
  • the hot air penetrating into the mouth of the upstream line section 11 only presses the solvent of the solvent circuit back into the reservoir 5 or is present at the then closed shut-off valve 28, so that no hot air can escape here.
  • the air recirculation flap is on the filter housing during this hot air drying of the filter dirt 3o still closed. Then the air recirculation flap 27 is opened, whereby the valve 26 can be closed, so that the filter dirt is still aerated.
  • the filter insert 9 which can be formed, for example, by a filter paper or a filter fleece, can be removed via a door of the filter housing 3o and discarded. It is also possible to wash out the filter so that it can be used again.
  • a blower 43 can be switched, which increases the throughput of the hot air through the filter device.
  • This blower can either be connected in the first air line 25 or — as in the exemplary embodiment — into the second air line, which in the exemplary embodiment is formed by the line section 11 of the solvent circuit that is downstream of the filter device 8 and connects it to the treatment chamber 3.
  • the second one may be more appropriate for reasons of space.
  • an arrangement of the blower in the second air line, that is to say in the line section 11, with respect to the recirculating air flap 27 on the inlet side of the filter device 8 is favorable, since in this way the blower 43 subsequently to the warm air has an increased amount of recirculating air via the flap 27 sucks.
  • blower 43 or its motor is operatively connected to the conveyor device 2o of the hot air circuit in such a way that both are switched off or on simultaneously.
  • first air line 25 opens in the area of the outlet of the air heater 18 and is expediently within the system housing 1 to the air heater outlet, that is to the hottest point, as indicated by dashed lines.
