    Wet laundry 10 in a vessel 12 supported on a drainage plate 14 is dewatered by a combination of mechanical pressure applied by a platen 33 and air flow through the platen and laundry. The platen is initially brought down upon the laundry by a cylinder 42 to compress it and squeeze out about half of the water, and drying air is simultaneously forced through the vessel from top to bottom via the platen and plate to remove additional moisture. The platen pressure may be reduced to enhance the air flow.

    This invention relates to industrial presses that are used in large laundries,
    The purpose of the invention is to reduce the time of dehydration.
    Figure 1 shows the device, a section along a vertical plane; Fig. 2 shows a section A-A in Fig. 1 (shifted by 90 relative to Fig. I); in fig. 3 device, in plan or top view; in fig. 4 - section BB in FIG. in fig. 5 - plunger plate, vertical section; in fig. 6 back pressure plate with support; in fig. 7 radial section through a detail of the locking device; in fig. 8 - the same, top view of the part 7.
    The device comprises a cylindrical tank 1 for laundry 2, which is supplied to the tank 1 via an inclined draining tray 3, coming from a washing or rinsing machine, usually together with rinsing water. At the feed end of the batch of bel 2, tray 3 is retracted to the side.
    The bottom of the tank 1 is made in the form of a perforated plate 4 and is detachable with the tank body.
    In order to perceive significant pressure forces, the thin-walled plate 4 rests on the lower structure that can withstand the load, namely the main lower base plate 5, which is formed from hollow profiles, namely, with longitudinal 6 and transverse walls, as stiffeners between the upper and lower base plates 8.9. The support plate 5 thus formed rests on the sides, on the support columns 10.
    The plate 4 is made in such a way that the water flowing from the laundry 2 can be removed from the tank 1. For this purpose, the plate 4 is supplied with channels 11 passing transversely to the direction of movement of the endless mesh conveyor 12, in the form of openings on the top. Flowing water falls into them and is diverted to the side. On the upper side of the slab, under the perforated bottom of the tank, is the upper branch 13 of the mesh conveyor 12, by means of which, after the dewatering process has been completed, the batch 2 is transported to the conveyor belt 4, the driving and turning rollers 15 of which are located

    wives adjacent to the rotary roller 16 of the mesh conveyor 12. The second rotary roller 17 is on the opposite side relative to the support plate 5. One of the rotary rollers 16,17 is driven. The lower branch 18 of the mesh conveyor 12 extends from the lower side of the base plate 5 between the supporting columns 10.
    The tank 1 is placed in a tank 19 for collecting a liquid, at the bottom of which 20 stand supports 10.
    A pressure device 21 is installed above the tank 1. The latter consists mainly of a plunger 22 with a hollow plunger plate. The latter, under pressure, is moved in height along the axis of the tank 1 for mechanical pressure on the laundry 2. For this purpose, on. The vertically displaceable pressure beam 23 is mounted with a pressure plunger 22 with a hollow plate 24 of the plunger.
    The latter, in turn, side slides 25 and
    26 pushes vertical racks 27 and 28. The plunger 22 or plunger plate 24 is outside on the sides so that they fit into tank 1 tightly, do not allow air to pass through, and are adjacent to the cylindrical body of tank 1 when moving up and down.
    FIG. Figures 1 and 2 show the upper remote position from the tank I, the initial position of the pressure device 21. To dehydrate the laundry 2 by pressing it inside the tank 1, the pressure yoke 23 together with. push plunger
    22 and plate 24 of the plunger is moved down to the lower working position facing the tank 1 (not shown). To this end, with a pressure beam
    23, two vertical drive shafts 29 and 30 are engaged. By means of the latter, the push bar 23 can move along guide racks 27
    and 28 up and down.
    The vertical rods 29 and 30 rest on the frame 31. The latter connects the upper ends of the guide pillars 27 and 28 to each other. The guide pillars 27 and 28 are so connected to the frame 31 that they can transmit considerable forces.
    Bottom ends of guide posts
    27 and 28 are connected to the base plate
    5 so that the support plate 5, the guide posts 27 and 28, and the frames 31 form a frame structure capable of carrying the load in which the device 21 is supported.
    To transfer the required pressing force to the pressure plunger 22. Or a hydraulic cylinder 32 is provided on the plunger plate 24, which is installed in the middle of the plunger plate 24. The hydraulic cylinder 32 is connected to the pressure beam 23 and therefore, as part of the pressing device 21, it can move up and down. The piston rod 33 is connected to the upper hub 34 of the plunger 24 plate. The relatively short stroke hydraulic cylinder 32 is used only in the lower operating position of the pressure device 21 in order to transmit a large pressing force to the plunger plate 24. In this lower position, the reaction forces from the pressure device 21 are transmitted through the support to the frame 31. For this purpose, two support punch 35 and 36 are mounted on the pressure beam 23. They can be raised and lowered together with the pressure beam 23 so that in the lower working position the upper, free ends of the support punches 35 and 36 are located under the pivot plate 37 mounted on the underside of the frame 31. The annular pivot plate 37 can move between the open position (figure 2, figure 7) and the locked position (shown m in phantom in Figure 8) such as to pivot about 15. The pivot plate 37 is provided with guide holes 38 and 39, which in the open position correspond to the bearing punches 35 and 36. The latter, in the upper position of the pressing device 21, also pass through the guide holes 38 and 39 in the up and down movement In the working position, the support punches 35 and 36 are directly below the pivot plate 37, so that the support punches 35 and 36 abut on the turntable 37, as a result of which the reaction forces can be transferred to the frame 31.
    In a special way, the plunger plate 24 is made on the floor (figure 5). The bottom wall of the plate 24 plunger facing
    The tank 1, namely the pressure surface 40, is made concave inwards, so that the laundry 2 in the region of this plate is pressed out from the tank walls to the beginning of its removal. A plate 24 of plungers thus made serves simultaneously to supply a gaseous medium (air) to the laundry. For this purpose, a compressed air line 41 is connected to the plunger plate 24, namely to its hub 34. Under the rod, the threshold 33 of the pressure cylinder 32 forms a space 42 of compressed air, which through the hole 43 is connected to the lower side of the plunger plate 24 and therefore with radial ribs installed there, directed transversely, open to the lower side, distribution channels 44. Sub. the bottom side of the plunger plate 24 also has a concave-shaped wall configured as a grid 45. Through the organs described above, the air is distributed evenly in the tank 1 and this is conducted through the laundry 2. In the area of the hole 43, a check valve 46 is installed, which prevents the backflow air or reverse flow of water, in particular during the phase of mechanical compression of the pressed laundry.
    The tank 1 can be lifted from the plate 4. For this purpose, two lifting power cylinders 47 and 48 are supported on one side of the support plate 5 by one side, and the other side is connected to the projections 49 and 50 of the tank body 1. By extending the lifting power cylinders with a piston rod 47 to 48, the tank body 1 is lifted from the plate 4 so that the dried batch of linen 2 can be removed by means of the mesh conveyor 12. In the area of the protrusions 49 and 50 for this purpose, the tank body 1 is connected to the guide posts 27 and 28 via sliding supports.
    The device works as follows.
    After the batch of wet laundry 2 is introduced into the tank 1 placed on the slab 4, the pressure device 21 of the pressure beam 23 moves to the lower operating position and is locked. The plunger plate 24 is in this position, approximately 20-30 mm above the upper edge of the tank body 1.
    The plunger plate 24 is then loaded by the pressure cylinder 32. The plunger plate 24 moves downward with a quick movement until a predetermined pressure is reached in the tank 1 or in the hydraulic system of the hydraulic cylinder 32 due to the back pressure of the bel 2, which is preferably about 50% of the maximum pressure dehydration. Then the movement of the plunger plate 24 is transferred to a slower speed before the preset maximum pressing pressure is reached, for products made of cotton, preferably 25.0 kgf / cm, and for products made of mixed fibers (cotton and synthetics) 10.0 kgf / cm Following this, further downward movement of the plunger plate takes place, while at the same time maintaining the predetermined maximum dewatering pressure, before the dehydration time that has been set in advance, since the laundry is still being compressed. But alternatively, this further downward movement of the board 24 does not occur, and it lies on the laundry only with its own weight, which mainly affects the dehydration time, since it thereby accelerates the flow of air through the laundry.
    The means for in-line dewatering (air) is put into operation with a time shift relative to mechanical dewatering and, preferably, precisely after the predetermined maximum pressing pressure of the plunger plate 24 has been reached, hence upon completion of the downward movement at creeping speed. Continuous dehydration is carried out before a specified time has elapsed. Mechanical pressing and continuous dehydration occur in the same direction. Mechanical dehydration occurs to a residual moisture content of 50-45%. The subsequent flow dewatering follows to a residual moisture content of 40–30%, and, if necessary, mechanical spinning is continued, if the maximum dewatering pressure is maintained.
    1. A method of dewatering the laundry after washing by pressing the laundry in two stages, the first of which is
    At the end of the combined pro-55, due to the mechanical pressure
    During the dewatering process, the plunger plate 24 remains in its lower end position. Tank body 1 by


    lift cylinders 47 and 48 are slightly raised (approximately n 20 to 20 mm) to release the linen cake (linen 2 after dehydration) from the tank 1 body. Then, the pressure device 21 is released by turning the plate 37 to its original position. The traverse bar 23 now moves to its upper initial position. Immediately following this, the piston rod 33 of the hydraulic cylinder 32 is retracted by rapid movement. Only then does the further movement of lifting the tank 1 body with the help of lifting power cylinders 47 and 48 to the upper end position (approximately 300 "m, total lift) lying on the conveyor belt - the linen pie can now be transported.
    It is especially advantageous to produce dehydration of linen from blended fabrics (cotton and synthetics) using normal unheated air at a pressure of 4.0 bar and linen from cotton at a pressure of 6.0 bar.
    It is also possible to apply pressure, at least for a linen made of cotton, up to 10.0 bar. Lingerie made from blended fabrics, due to its greater sensitivity, is always subjected to less pressure than the pressure for cotton. When using normal compressed air at a pressure of 4.0 or 6.0 bar, the energy savings are greatest.
    Normal compressed air or air with a temperature of the room or the environment in this case is the produced by means of pressure or compressed air, which is filtered in the usual way before the device is used, especially oil-free.
    Compressed, supplied to linen, can heat up to 80-1УО С, mainly up to 110 ° С.
