Definitions

  • the invention relates to a washing installation for items to be washed, preferably for gravel with ablurrable constituents, which is fed to a trough, in the longitudinal axis of which a washing shaft equipped with comminution and / or washing and / or transport tools is arranged, and with at least one water inlet the water flows into the trough, preferably against the transport direction of the laundry.
  • the object of the invention is to provide a washing installation of the type mentioned, in which the washing effectiveness is considerably increased by a new arrangement geometry and design of the comminution washing and transport tools.
  • the crushing, washing and transport tools should be attached to the washing shaft so that their quick and easy replacement is still possible without the way in which the cutting, washing and transport tools are weakened on the washing shaft.
  • washing shaft which are staggered in the longitudinal direction with optionally one to six comminution and / or washing and / or transport tools distributed over their circumference.
  • the washing system can thus be adjusted to any material and individual problem without design changes.
  • the tools can be swords extending essentially in transverse planes, which preferably have a semi-open profile, the open side of which points away from the washing shaft.
  • the swords are suitable for clogging with washable parts, especially clay and clay.
  • a semi-open profile is to be understood as any profile that has this effect; in particular, a U-profile, flat iron profile, a trapezoidal profile, an L-profile, a partially cylindrical profile or another claw-shaped profile can be considered.
  • the sludge settling in the profile opening and thus held for a certain time Ren constituents of the laundry are dissolved and washed away in a continuous process by the action of water and the friction of the granular constituents moving back and forth in the longitudinal direction of the sword. Thanks to the high pressure and the correspondingly high friction, which is achieved by the geometrical arrangement of the swords, there is a very high washing effectiveness, which makes it possible to treat problematic laundry items that were not previously usable.
  • Two swords can be attached to the washing shaft in diametrically opposite, preferably parallel, arrangement. This gives a symmetrical structure which can be implemented with little expenditure on equipment and which leads to pressure build-up and reduction in the trough at a frequency which is doubled compared to the speed of the washing shaft.
  • the swords adjacent in the longitudinal direction of the washing shaft can each be arranged offset from one another by an angle which is 90 ° or deviates slightly from 90 °.
  • the pressure peaks in the bottom area of the trough are thus offset over its length. This results in a more even energy consumption of the washing system, a lower overall energy requirement and a lower material load.
  • more than two, ie at least three and practically not more than six swords can also be arranged in a transverse plane, preferably distributed uniformly over the circumference of the washing wave.
  • a higher number of swords an effective cleaning and dissolving of loam and Clay components even if there is only a small amount of sand fraction causing a high internal friction of the laundry.
  • the swords are preferably detachably attached to the washing shaft in order to enable quick and easy replacement after wear.
  • only the outer ends of the swords are subject to considerable wear. It may therefore also suffice to provide head pieces on the outer ends of the swords, which are detachably attached to the swords or directly to the washing shaft. Replacing the head pieces after wear is much cheaper in terms of material requirements than replacing the entire swords.
  • An arrangement is preferred in which both the swords and the head pieces are detachably arranged on the washing shaft so that they can both be replaced after wear. If the same materials are used, new swords are only required every approx. Fifth change of a head piece.
  • the head pieces can have a half-open profile, the open side of which points away from the washing shaft.
  • the profile of the head pieces can match the profile of the swords, but can also be different. This gives you the option of opting for the composition of the laundry times to provide adapted head pieces and optionally use, which further increases the washing effectiveness.
  • a U-profile, flat iron profile, trapezoidal profile, L-profile, partially cylindrical profile or generally claw-shaped profile can also be considered for the head pieces.
  • the profiles of the swords and head pieces can be provided with openings, in particular in the form of holes or slots.
  • openings in particular in the form of holes or slots.
  • Such a sieve-like design of the profiles is recommended for laundry with a high proportion of fine sand, which can pass through the openings, so that the profiles are prevented from clogging too quickly.
  • edges of the profiles can be serrated. You have a saw-like design with increased cutting effect of the profiles, through which an effective comminution of clay and clay components of the laundry takes place.
  • Sheets can be arranged on the washing shaft at regular intervals, to which the swords and possibly also the head pieces are detachably fastened.
  • the sheets are welded onto the washing shaft. A weakening of the washing wave is thereby avoided.
  • the sheets can have a regularly triangular, rectangular or regularly hexagonal layout. This results in a corresponding number of assembly places for shredders tion and / or washing and / or transport tools.
  • Two sheets can form a pair at a short distance from each other, between which a nose welded to the back of the swords and possibly also the head pieces protrudes, which can be fixed there by means of a pin.
  • An end piece of the sword can be inserted into a slot in the pair of sheets, whereby the sword can be detachably attached to the pair of sheets.
  • the swords are attached to the metal sheets so that they cannot tip or twist.
  • Sheet metal strips made of a wear-resistant material can be fastened, in particular screwed, to the outside of the profile legs of the swords. These wear parts significantly increase the lifespan of the swords. A considerable reduction in price can also be achieved since the entire sword does not have to be made from the expensive, wear-resistant material.
  • the free ends of the sheet metal strips pointing away from the washing shaft can have a tooth profile in order to achieve the improved comminution effect already mentioned.
  • a transport arm is arranged offset by 90 ° between two diametrically opposed swords, which consists of a transport plate which is under one
  • the angle to the longitudinal axis of the washing shaft runs and on its edge facing the washing shaft has a pin approximately in the center, which is attached to the sheet or can be inserted between the pair of sheets and fixed there.
  • the pair of sheets thus advantageously serves to mount the swords and the transport sheet at the same time.
  • a free edge strip of the transport arm can be angled so that it can be attached to one of the profile legs or to the sheet metal strip arranged there. You have an extremely stable structure.
  • plate-shaped comminution and / or washing and / or transporter tools can also be provided, which preferably extend essentially parallel to one main plate direction and essentially tangentially to the washing shaft with the other main plate direction.
  • a plate body which encloses a wedge angle with the wall of the trough, exerts a very high pressure and a very strong friction on the laundry which is moved through the trough at a high conveying rate.
  • the plate-shaped tools can be attached to the washing shaft using the aforementioned sheets. In this way, it can be easily detached without any weakening of the washing wave.
  • each plate body should be supported on at least two of the sheets.
  • the surfaces of the plate bodies can be structured to form retention chambers that fill with laundry.
  • crushing and / or washing and / or transport tools in the form of medium-wide blades are also suitable. All of these tools can be combined with one another for optimal adaptation to the composition of the laundry.
  • the tools can be curved both straight and in the direction of rotation of the washing shaft, counter to the direction of rotation of the washing shaft or in some other way.
  • plates 11 are arranged in pairs at regular intervals, so that there is a small distance between two plates.
  • the sheets 11 are welded to the washing shaft 10 almost along a semicircle. Two such pairs of sheets are diametrically opposed to each other at the same height as the washing shaft 10.
  • the plate pairs 11 adjacent in the longitudinal direction of the washing shaft 10 are arranged offset by 90 °. An arrangement offset by more than 90 ° or less than 90 ° is also possible.
  • the sheets 11 have a projection 12 on their lower edge pointing away from the washing shaft 10, which together with the sheet 11 forms a slot 13.
  • a U-profile rail 14 is inserted with its lower end piece, which abuts the metal sheets 11 with its rear side, a welded-on nose 15 protruding between the metal sheet pair 11 and being fixed there by means of a pin 16.
  • the U-profile rail 14 is thus tilt and twist-proof on the pair of sheets attached.
  • Sheet metal strips 17 made of a wear-resistant material are screwed onto the outside of the legs of the U-shaped rail 14.
  • the free edges of these sheet metal strips 17 pointing away from the washing shaft 10 have a tooth profile 18 which effectively supports the division of the lumps of clay and sand.
  • a transport arm 19 can be arranged between two diametrically opposed U-shaped rails 14, which consists of a transport plate 20 which runs at an angle to the longitudinal axis of the washing shaft 10.
  • the transport plate 20 has on its edge facing the washing shaft 10 approximately in the middle a pin 21 which is inserted between the pair of plates 11 and fixed there.
  • a free edge strip 22 of the transport plate 20 is angled so that it can be fastened to one of the legs of the U-shaped rail 14 or to the wear-resistant metal strip 17 arranged there.
  • Each U-profile rail 14 lies with a considerable part of its length on two diametrically opposed pairs of sheets 11, so that the bending moment acting on the profile rail is small during operation of the washing system. If you want to replace the swords 14, it is sufficient to knock out the pin 16 and pull the rail out of the slot 13. This can even happen when the washing trough is full. Even the transport arms 19 can be quickly and easily removed or replaced at any time, depending on the speed at which the items to be washed are to receive in the washing trough.
  • the design and attachment of the swords and transport arms according to the invention can also be used without problems with a washing shaft 10 with a square cross section.
  • the swords 14 each lie on a square surface of the shaft 10.
  • the transport arm 19 rests in the case of the action of bending forces with its free end piece after a short bending path on one leg of the U-profile rail 14. This prevents the transport arm 19 from breaking off.
  • Fig. 3 shows in detail how the U-profile rail 14 is inserted with one end into the slot 13 provided on the pair of sheets 11.
  • the U-back of the profile rail 14 comes to rest in the slot 13, while the projection 12, which divides the slot 13 together with each sheet 11, engages like a claw in the U-opening of the U-profile rail 14.
  • the swords 14 and head parts 23 have a matching round profile which is open on one side and is provided with teeth 31 on the outer edge.
  • the head part 23 abuts the face of the associated sword 14 in an aligned arrangement.
  • the swords 14 have two on their profile back attached tabs 29, which have a rectangular plan and come to lie at some distance from the outer edge 30 of the sheets 11 between them.
  • the tabs 29 are screwed to the metal sheets 11 at 32.

  • Each transport arm 22 consists of an angle plate 33 and a wear plate 34 welded thereon, which extends at a short distance over the back of the adjacent pair of swords 14, which are arranged at 90 °.
  • the additional transport plates 20 are used to adapt the conveying capacity of the washing shaft to the respective needs.
