Definitions

  • the invention relates to a washing system for laundry, especially for those with drainable Constituent gravel, with a trough that the Laundry is fed and in its longitudinal axis a washing shaft is arranged, the crushing and Washing tools are stocked on the periphery start the wash shaft, a half-open profile with a straight profile axis and with one at the front in the direction of rotation of the washing shaft Have profile opening and with the wall of the trough in Direction of rotation of the washing shaft a wedge angle of less Include as 90 °, and with at least one Water inlet, through the water into the trough, preferably against the transport direction of the laundry flows.
  • Such a washing system is from EP-A-0 224 920 known. It has shredding and Washing tools that are approximately radial to the Start the washing wave. Because of one alone Minor material thickness of the tools There is a small offset from the radial direction Wedge angle of negligible wedge effect with the wall of the trough.
  • the tools of EP-A-0 224 920 assets over the displacement resistance of theirs Pressure to exert pressure on edges however, this pressure build-up occurs essentially alone in the axial direction. For a noteworthy Pressure build-up is a high level in EP-A-0 224 920 of the trough required.
  • the object of the invention is to provide a washer to create the type mentioned at the same time Drive power a higher pressure and a to exert correspondingly greater friction on the laundry suitable and opposite the car wash EP-A-0 224 920 significantly improves its washing effectiveness and already at a much lower level the trough is fully functional.
  • the invention Generate tangentially oriented tools a pressure in the circumferential direction by adding laundry between the half-open profile in the direction of rotation the tools and the trough wall are wedged and is crushed. To be more precise, he firmed himself up Trough in operation, d. H. the trough wall forms around the wash wave and the tools Tanks of clay and / or clay and in it pressed gravel, between and the tools the laundry is wedged and a high pressure build-up takes place in the circumferential direction.
  • the car wash according to the invention has one such as that of EP-A-0 224 920 significantly improved washing performance.
  • GB-A-477 776 is a washing system with a trough and one in the longitudinal direction extending square shaft known on the periphery Beater arms with essentially tangential Start extension.
  • the beating arms are not profiled. They are designed to serve when the rotation is fast Wave an intense water movement with swirls and Generate currents in the wash water itself but only to a small extent on the clay, etc. act.
  • GB-A-477 776 has the ends of the striking arms such a distance from the wall of the trough, that the largest lumps or stones to be expected cannot wedge. From this as well as from the The shaft is driven by a pulley, that the striking arms have no significant pressure the items to be washed are suitable.
  • the striking arms are alone in the GB-A-477 776 for technical assembly reasons with tangential orientation attached to the outer surfaces of the square shaft. Because of the out-of-round shape of the trough, the not mashed up with this fast-rotating car wash, is the wedge angle that the striking arms use enclose the wall of the trough, none defined Size. GB-A-477 776 wants to wedge material just prevent and over those with the blow arms generated water movement an indirect washing effect cause. The washing performance achieved in this way is low. As is apparent from GB-A-477 776, that is described Car wash is actually unable to make clay tubers dissolve what washing success is crucial.
  • the tools can essentially be found in Swords extending across planes.
  • Two swords can be diametrically opposed to each other opposite, preferably parallel arrangement be attached to the washing shaft. You have that a symmetrical structure, with little can be realized in terms of equipment and at one Pressure build-up and release in the trough with one opposite the speed of the wash wave doubled frequency leads.
  • the neighboring in the longitudinal direction of the washing wave Swords can each be at an angle to each other be arranged offset, which is 90 ° or deviates little from 90 °.
  • the generation of the pressure peaks in the bottom area of the trough this is done via the trough Length offset. This will result in a more uniform Energy consumption of the car wash, one overall lower energy consumption and a lower Material load.
  • more than two, i.e. H. at least three and conveniently no more than six Swords in a transverse plane are preferred evenly distributed over the circumference of the washing wave be arranged.
  • the swords are preferably detachable from the Wash shaft attached to after wear enable quick and easy replacement.
  • only the outer ends are subject to Swords a considerable wear. It can therefore also suffice at the outer ends of the swords
  • head pieces that are detachable on the swords or are attached directly to the washing shaft.
  • the head pieces should be replaced after wear in terms of material requirements much cheaper than one Exchange of the whole swords.
  • the head pieces have just like the swords semi-open profile, the open side of which Wash wave points away.
  • the profile of the headers can match the profile of the swords, but also be different. So you have the opportunity to the composition of the laundry is optimal provide customized headers and optional use, which further increases the washing effectiveness is increased.
  • For the swords and head pieces is on U-profile, flat iron profile, trapezoidal profile, L-profile, partially cylindrical Profile or generally claw-shaped profile to think.
  • the profiles of the swords and head pieces can with openings especially in the form of holes or slots. Such a sieve-like
  • the design of the profiles is recommended for items to be washed a high proportion of fine sand caused by the breakthroughs can pass through, so that too fast Clogging of the profiles is prevented.
  • the edges of the profiles can be serrated.
  • Man has a saw-like design with increased cutting effect of profiles through which an effective Comminution of clay and clay components of the Laundry is done.
  • On the wash wave can be in regular Intervals sheet metal, on which the swords are arranged and, if necessary, the head pieces can also be detached are attached.
  • the sheets are preferred Embodiment welded onto the washing shaft. This prevents a weakening of the washing wave.
  • the sheets can have a regular triangular shape, rectangular or regular hexagonal layout to have. This results in a corresponding one Number of assembly places for shredding and Washing tools.
  • Two sheets can be spaced a short distance apart form a pair, between the one at the back the swords and possibly also the Head pieces welded nose protrudes, which means there a pin can be fixed.
  • a tail of the sword can slide into a slot in the pair of sheets leave, making the sword releasable on the pair of sheets is attachable.
  • the swords become tilt and twist-proof attached to the sheets.
  • the free ones pointing away from the washing wave can have a tooth profile, to the improved already mentioned To achieve crushing effect.
  • a transport arm arranged offset by 90 ° which consists of a Transport sheet exists, which is at an angle to Longitudinal axis of the washing wave runs and at its to
  • the edge of the washing shaft has a spigot in the middle has, which is attached to the sheet or itself stuck between the pair of sheets and fixed there.
  • the pair of sheets thus advantageously serves at the same time for mounting the swords and the transport plate.
  • a free edge strip of the transport arm can be angled so that it is on one of the profile legs or on the sheet metal strip arranged there can be attached. You have an extremely stable structure.
  • swords can also be plate-shaped Crushing and washing tools provided be preferably with one Main plate direction essentially parallel, and with the other main direction of the plate essentially tangential extend to the wash shaft.
  • one Panel body that makes a wedge angle with the wall of the trough becomes a very high pressure and exerted a very strong friction on the laundry, that moves through the trough at a high rate becomes.
  • the attachment of the plate-shaped tools the washing wave can with the aforementioned sheets respectively. It is a convenient detachable attachment possible without any weakening of the washing wave. in the Every plate body should be interested in a high stability Support at least two of the sheets.
