Definitions

  • the invention relates to a device that can be carried in the cleaning work and is arranged on a rollable or slidable gesture for removing dirty water from cleaning textiles, in particular covering of cleaning devices.
  • the cleaning textiles used for wet cleaning get dirty during the cleaning work and therefore have to be cleaned at regular intervals:
  • the conventional wiping cloth is repeatedly rinsed out and wrung out in the water bucket.
  • the textile coverings of cleaning devices are difficult to wring.
  • the device mentioned at the outset was created for them in the form of handy, light and simple presses. In the presses, the press jaws are pressed together or driven between rubber pressure rollers or the like.
  • the invention has for its object to further improve the removal of the dirty water from cleaning textiles with a justifiable effort.
  • this purpose is achieved by a centrifuge with a centrifugal drum arranged in a housing and provided with passages on the circumference.
  • Dry spinning is known per se. In order to achieve the required speeds, however, they are equipped with more sophisticated drives, regular electric motors, which have to be tightly encapsulated in the wet environment and mean effort and weight.
  • the dry blowers are installed in a fixed place.
  • the invention is based on the idea and knowledge that, in order to bring cleaning textiles to the moisture content suitable for their use or even a lower one, simple, light types of centrifuges are also possible, which are designed and used in the manner mentioned at the beginning can be.
  • a hand crank drive with a one-way clutch can be provided. This allows the centrifugal drum to be brought up to a comparatively high speed by hand with a short, fast drive and then to be freely rotated before what happens with the fast movement after a short time, muscle tension and fatigue occurs.
  • the hand crank drive has a worm gear with the worm on the shaft of the centrifugal drum or on a continuation of the shaft.
  • the worm is mounted in the present case in a longitudinally displaceable and rotationally free manner on the shaft or its continuation and, due to the force exerted on the hand crank in the drive direction of rotation, is axially displaceable on a rotationally fixed coupling part with which it engages by means of an axial helical toothing has such that power transmission in the opposite direction cancels the intervention.
  • the freewheel is thus realized in a very simple and expedient manner.
  • the devices can be further expanded according to the invention in that, by exerting force on the hand crank in the opposite direction, the worm can be displaced axially on the other side onto a turnstile and against a non-rotatably arranged brake actuator on the shaft or continuation and thus in a simple manner by turning back can be braked.
  • centrifugal drum is designed as a narrow ring vessel, preferably with a transverse cover holding the centrifugal drum on its shaft in the inner ring wall, preferably at the open end of the ring vessel.
  • a textile covering of a cleaning device can, if necessary once folded lengthways, be inserted into the ring vessel following the curvature.
  • the ring vessel is also advantageous for other cleaning textiles, in particular stiffer ones.
  • the shaft of the centrifugal drum can be expediently supported in a stand or the like, starting from the floor with the rear wall arranged horizontally, or the like.
  • the centrifugal drum is expediently arranged with a vertical axis. This makes it easier to load, especially when it is designed as a ring vessel. A horizontal arrangement would be possible.
  • the frame designated 1 consists mainly of a multi-curved tube: the legs of a U-shaped base 2 are bent upwards and then back into the horizontal, where they end with an inward bend 3 and the slingshot 4, directly on a base plate 10 whose housing 5, wear. At the base 2, two rollers 6 and two inclined feet 7 are attached.
  • a stand 11 made of cast aluminum, in which the shaft 12 of the centrifugal drum 13 is mounted on two thickenings 14 in self-lubricating bushings, not shown.
  • the upper bushing With a flange placed over the end face of the stand 11, the upper bushing also provides an axial bearing for the shaft 12, which in turn lies with a flange 15 on the flange of the bushing.
  • the flange 15 carries a disc 16 with which it is welded at 17.
  • the centrifugal drum 13 which is designed as an annular vessel 18, is fastened on the disk 16 in that a transverse cover 19, into which the inner wall of the annular vessel 18 merges at the top, lies on the disk 16. At the bottom, the inner wall is folded over to the bottom of the ring vessel.
  • the casing 21 of the centrifugal drum which consists of a perforated plate, is fastened to an edge 20 of the base.
  • the housing 5 is provided with a latching hinged lid 22.
  • the shaft 12 is led out of the housing 5 through the hinged cover 22 with a continuation 24 connected via a plug-in coupling 23.
  • the plug-in coupling 23 consists of a through a transverse pin 25 with play and thereby a little wobble on the shaft 12 attached socket 26 with an internal hexagon and a corresponding hexagon 27 on the continuation of the shaft.
  • Conical bevels at the lower end of the hexagon 27 and at the upper end of the hexagon socket and, if necessary, a slight taper of the hexagon 27 and the hexagon socket itself allow the coupling parts to be found when the hinged cover 22 is put on.
  • a worm 33 is seated on the continuation 24 without rotation and axially displaceable.
  • the lower end of the worm 33 is designed as a counterpart to the coupling part 31 with two teeth, each of which has a vertical and an elongated oblique flank.
  • the upper end is conical as a counterpart to the brake cone having a conical friction surface 32 and is provided with two notches 34 which, depending on the position, can push one or the other onto the end of a screw 35 projecting through the housing wall.
  • a gear 36 meshing with the worm 33 is mounted with its shaft 37 in a connecting piece 38 of the gear housing.
  • a hand crank 39 sits on the outer end of the shaft 37.
  • the hand crank 39 In order to stop the centrifugal drum 13, the hand crank 39 is moved in the opposite direction.
  • the gear 36 then pushes the worm 33 upwards.
  • the worm 33 lies with one of the two incisions 34 on the screw 35 as a turnstile and then presses on the brake actuator 32 in a braking manner.
  • an inserted into the ring vessel 18, e.g. once folded covering 40 of a cleaning device is indicated.
  • the wastewater expelled therefrom runs through an outlet, not shown, out of the housing 5 into a bucket below it on the base 2 of the frame.
  • crank handle 39 is used in the raised position as a handle for lifting the feet 7 and moving the entire device by means of the rollers 6.
  • the drive 28 arranged on the hinged cover 22 is attached in a preferred embodiment in the reverse position on the bottom of the housing 5, more precisely on the base plate 10.
  • the shaft 12 then extends further downward and possibly through the bottom of the housing 5 and the gear housing 30.
  • a coupling which may be designed somewhat differently from the plug-in coupling 23, could again be provided between the shaft 22 and the continuation 24, for example in the cavity of the stator 11.
  • An electric drive is not preferred, but is not excluded.
  • the device can also consist at least partially of plastic.
