Abstract

A washing device for material for washing, in particular for gravel mixed with elutriatable components has a washing shaft (10) which runs in a trough and is equipped with comminuting washing and conveying tools. The tools fit on the periphery of the washing shaft, (10). They extend essentially at a tangent to the washing shaft (10) and enclose with the wall of the trough a wedge angle of less than 90 DEG . Preferably, the tools have a section which becomes clogged with material for washing. <IMAGE>

Description

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.

This task is accomplished with such a car wash solved that the tools with the profile back attach tangentially to the washing shaft so that the open side of the profile points away from the washing shaft.

Thanks to the tangential orientation of the Crushing and washing tools is in the invention Car wash a significantly higher Pressure build-up on the laundry is possible than that in the Washing system of EP-A-0 224 920. 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. It gets low Level of the trough a high pressure on the Items reached. The tools move with it pulling cut through the laundry, whose drainable parts due to friction on the Tools dissolved and washed away very effectively will. With the high pressure in the circumferential direction goes a correspondingly strong friction and Disintegration effect. The car wash according to the invention has one such as that of EP-A-0 224 920 significantly improved washing performance.

From 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 striking arm arrangement in the car wash of the GB-A-477 776, after all, gives no indication that with tangentially oriented shredding and Washing tools that have an open front in the direction of rotation Profile, wedge laundry and under high To build up pressure and crush. The high-speed water swirling with the blow arms, their only weak impact on the clay, etc. and that explicitly avoided with the blow arms Rather wedging of laundry leads to this affording car wash away.

Due to the eccentric arrangement of the Crushing and washing tools with essentially tangential orientation and their with the wall of the trough in the direction of rotation of the washing shaft Wedge angle becomes high with periodic friction Pressure impulses achieved on the laundry. It there are pressure peaks when the tools are one essentially horizontal orientation in the floor area of the trough. In this phase comes the Movement of the tools of a press die Near. The pressure spike will also quickly return degraded, which affects the energy requirements of the car wash has a favorable effect. In the phases of lower pressure take the tools skew a, in which the laundry due to gravity or dismantling the in the bottom area of the trough generated pressure moves along the tools and thereby causing friction.

It can be staggered lengthways Sections of the wash wave with either one to six shredding and spread over its scope Have washing tools loaded. The car wash can be done on any material without design changes and the individual problem can be set.

The tools can essentially be found in Swords extending across planes.

Thanks to the high pressure and the corresponding strong friction caused by the geometric arrangement the swords is scored, there is a very high one Washing effectiveness, which the treatment so far not usable, problematic laundry.

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.

However, 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. By a higher number of swords effective cleaning and dissolution of Clay and clay components even when one sand fraction causing high internal friction of the laundry is only present to a small extent. One can yourself by choosing an appropriate number of swords the composition of the laundry adjust so that it is cleaned optimally.

The swords are preferably detachable from the Wash shaft attached to after wear enable quick and easy replacement. In fact, only the outer ends are subject to Swords a considerable wear. It can therefore also suffice at the outer ends of the swords Provide 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. One is preferred Arrangement 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 can. When using the same materials, new ones Swords only with every fifth change of one Head piece required.

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.

On the outside of the profile legs of the swords can make metal strips from a wear-resistant material attached, in particular screwed on. By these wear parts will extend the life of the swords significantly increased. Can also be considerable Reduction can be achieved because not the entire sword made from the expensive wear-resistant material must become.

The free ones pointing away from the washing wave The ends of the metal strips can have a tooth profile, to the improved already mentioned To achieve crushing effect.

In a preferred design there is between two diametrically opposed swords 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.

Instead of 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. Through 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.

In addition to narrow ones with a hollow profile Swords and wide plates also come Crushing and washing tools in the shape of medium widths Shovels into consideration. All of these tools can for optimal adaptation to the composition of the laundry can be combined.

On a wash shaft 10 of a car wash for with drainable constituent gravel, the a washing trough is fed in the longitudinal axis The washing times are arranged regularly Intervals sheets 11 arranged in pairs, so that There is a small distance between two sheets. The bleach 11 are almost along a semicircle the washing shaft 10 welded. Two such pairs of sheets are diametrically equal to each other Now 10 opposite. The in the longitudinal direction of the Now 10 neighboring pairs of sheets 11 are around 90 ° offset. One by more than 90 ° or arrangement less than 90 ° is also possible.

The sheets 11 point to their from the washing shaft 10 groundbreaking lower edge a projection 12, which forms a slot 13 together with the sheet 11. In this slot 13 is a U-profile rail 14 with your lower end piece inserted with its back abuts the sheets 11, one on the back welded nose 15 protrudes between the pair of sheets 11 and is fixed there by means of a pin 16. The U profile rail 14 is thus safe from tipping and twisting attached to the pair of sheets.

On the outside of the legs of the U-profile rail 14 are sheet metal strips 17 made of a wear-resistant Screwed on material. The washing machine 10 groundbreaking free edges of these metal strips 17th have a tooth profile 18, which the division of the Lumps of clay and sand effectively supported.

Between two diametrically opposed ones U-profile rails 14 can be a transport arm if necessary 19, which consists of a transport plate 20 exists, which is at an angle to the longitudinal axis of the Wash wave 10 runs. The transport plate 20 instructs its edge facing the washing shaft 10 approximately in the middle a pin 21 which between the pair of plates 11th inserted and fixed there. A free edge strip 22 of the transport plate 20 is angled so that it on one of the legs of the U-profile rail 14 or the wear-resistant metal strips arranged there 17 is attachable.

Each U-profile rail 14 lies with a considerable Part of their length at two diametrically opposite each other standing sheet metal pairs 11, so that on the profile rail effective bending moment when operating the Car wash is small. If you want to exchange swords 14, it suffices to knock out the pin 16 and pull the profile rail out of the slot 13. This can even happen when the washing trough is full. The transport arms 19 can also be quickly and easily remove or reset at any time, depending on what transport speed the laundry in Wash trough should receive.

The design and attachment according to the invention the swords and arms can be easily moved even with a washing wave 10 with a square Use cross section. The swords are 14 each on a square surface of the shaft 10.

It is also advantageous that the transport arm 19 in Case of the application of bending forces with its free End piece after a short bending path on one leg the U-profile rail 14 rests. This will make a Avoid breaking the transport arm 19.

Fig. 3 shows in detail how the U-profile rail 14 with one end in the provided on the pair of sheets 11 Slot 13 is inserted. The U back of the Profile rail 14 comes to lie in the slot 13, during the projection 12, the slot 13 compartments together with each sheet 11, claw-like engages in the U-opening of the U-profile rail 14.

4 and 5 have the swords 14 and headboards 23 a matching half-sided open round profile with a toothing on the outer edge 31 is provided. The head 23 abuts in alignment Arrangement on the front of the associated Schwerts 14. The swords 14 have two on their Profile back attached tabs 29, one have a rectangular plan and some distance apart from the outer edge 30 of the sheets 11 between come to rest. The tabs 29 are at 32 screwed to the sheets 11. The head part 23 is with provided a tab 25, the outside of the tabs 29 of the swords 14 protrudes between the sheets 11 and occupies its full width. The tab 25 arrives the tabs 29 of a pair opposite each other Swords 14 to the system, and it is at 26 with the Bolts 11 screwed.

6 and 7 is the additional attachment of Transport plates 20 on the for fastening the swords 14 and headers 23 serving mounting points illustrated. The transport plates 20 are on the outside Sheets 11 placed and screwed through with bolts 26, 32, which the sheets 11 and tabs 25, 29 of the Push through swords 14 and headboards 23. Everyone Transport arm 22 consists of an angle plate 33 and a wear plate 34 welded onto it a short distance above the back of the neighboring pairs of swords offset by 90 ° 14 extends. The additional attached transport plates 20 serve to improve the conveying capacity of the Adapt wash wave to the respective needs.

9 to 12 are possible profiles for the sword 14 and the head part 23 reproduced. Fig. 8 shows that already described U-profile with or without a center bar 55, Fig. 9 is a 90 ° angle profile with or without a central web 55, FIG. 10 a trapezoidal profile with or without a central web 55, Fig. 11 is a fork profile with a double bar in the middle and FIG. 12 shows a profile that is not to be regarded as half-open T-profile or flat iron profile. The profiles with center bar 55 are fork profiles with straight or inclined Tines. A tab 25 is indicated on the back of the profile, between the sheets 11 of a pair of sheets is sufficient, while the profile back is flush with the Outer edges of the sheets 11 is supported. With the profile 11 is an example of a double arrangement such tabs 25 indicated that a only sheet welded to the washing shaft 10 11 grasp in a claw shape. General are for those Swords 14 and headboards 23 of the invention Washer profiles suitable, one in the direction of rotation have a profile opening at the front of the washing shaft.

According to the invention, swords 14 can be the same profiled, but also differently profiled Headers 23 can be combined to adapt to carry out the respective laundry. At a high Large section openings are recommended for the sand content of the laundry. With high amounts of clay and clay it likes also recommend the headboards with reverse orientation attached to the swords so that their Profile openings facing the swords. The headboards then move like a plow through the Laundry to effectively dissolve it.

13 shows one for swords 14 and headboards 23 suitable U-profile, the U-back with holes 27 and slots 28 is provided by the fine-grained Components of the laundry can pass through. A corresponding sieve-like design is also for the other profiles possible.

14 and 15 are in the embodiment of FIGS Pairs of sheets 11 welded onto the washing shaft 10, which have an equilateral triangular layout and axially aligned in transverse planes extend. The plates 11 are plate-shaped Crushing tools 35 held. Every plate 35 extends in the axial direction of the washing shaft 10 over three pairs of sheets 11, supports itself with the Back on the outer edge and has three tabs 36, which protrude between a pair of sheets 11 each. In addition, 11 head parts 24 are on the sheet pairs supported, which is a radially outside of the plates 35 Have a U-profile. The head parts 23 are each one Pair of tabs 37 provided on the outside of the Sheets 11 come to rest and together with the Tab 36 of the plate body 35 at 38 with the sheets 11 are screwed. Are in the same place too Transport plates 20 attached. The brackets of the Headboards 23 each have a nose 39, which on the Outside of an adjacent plate body 35 is supported so that an over the scope closed, extremely stable structure results.

Wine shown in Figs. 16 to 19 can be plate-shaped Crushing tools 35 on the outside be structured so that containment chambers for themselves laundry to be fixed therein. According to 16, 90 ° angles 40 are welded onto the plate 35. Fig. 17 shows the same for parallel, and Fig. 19 for Crosspieces 41 arranged transversely to one another. 18 are semicircular profiles 42 on the plate 35 welded on.

Open hexagonal sheets 11 on the washing shaft 10 diverse mounting options for Crushing and transport tools based on 20 and 21 are exemplarily illustrated. Here are two swords 14 that have a serrated 18 U profile have, in diametrically opposite arrangement mounted on the sheets 11. The swords 14 lie with the back on the outer edge a pair of Sheets 11 on. A welded on the back, tab 49 projecting between the sheets 11 is at 50 screwed to it. On an adjacent one in the circumferential direction Edge a mounting plate 51 is mounted, the Back of the sword 14 supports and for attachment a transport plate 20 is used. The inner end of the Retaining plate 51 comes to lie between the plates 11, with which it is screwed at 52. How to best seen in Fig. 21, a transport plate 20 of each carried a pair of axially offset holding plates 51. The transport plates 20 lie on the circumference the washing shaft 10 diametrically opposite in pairs. Similar to the transport plates 20, the can Swords 14 head parts 23 arranged radially on the outside be mounted on the hexagonal plates 11 (not shown).

To the two remaining as assembly sites Edges of the hexagonal sheets 11 are in each other diametrically opposed blade-like arrangement Crushing tools 43 attached, the one relatively large width, but less radial delivery have than the swords 14. The blades 43 lie with their back on the outer edge of the pair of plates 11 and they have one welded on their back Tab 53 on between the sheets 11 of a pair of sheets protrudes and is screwed to these at 54.

The based on the individual embodiments described crushing, washing and transport tools are largely interchangeable. You have such a modular system that Equipping a washing shaft 10 with the composition of the respective items to be washed optimally adapted shredding, washing and transport tools enables. The latter can be used instead of welded parts also be casting elements.
