- the sieve drum has an upper and a lower one Front wall and a cylinder jacket-shaped screen wall with Breakthroughs for the passage of the fine fraction.
- the device and the sieve drum is also inclined arranged upward axis so that the sand mixture enters the sieve drum diagonally upwards.
- the fine fraction passes through the perforations in the sieve wall, while the coarse fraction at the top of the sieve drum exit.
- the screening drum is used as a sand mixture in particular Sewer sand, street sweepings and / or sewage treatment sand.
- a device of the type described in the opening paragraph is known from Advertising letter from the applicant "Systematic sand preparation", RoSF, 8.1997.
- the sand mixture which in its composition can also change, is divided into a fine and a coarse fraction divided up. Coarse materials are included in the coarse fraction with a diameter> 10 mm.
- the device consists in essentially a drum with a relatively large diameter, which is a cylinder jacket-shaped screen wall with openings for the passage of the fine fraction.
- the axis of the Sieve drum is arranged at an incline, with the end of the task for the sand mixture is lower than the delivery end.
- the sieve drum has an upper and a lower end wall. Both end walls are at least partially open.
- the screening drum of the device is on rollers rotatably mounted.
- the sieve drum is on the outside with provided a ring gear. Via an intervening chain and the sieve drum is rotated by means of a motor added.
- the task of the sand mixture in this well-known Device difficulties The feed is increasingly in in liquid form via a pipeline and by means of a pump.
- the pipeline ends in the central opening of the lower end wall the sieve drum.
- street sweepings, Sewer flushing sand and other sand mixtures in bunkers or low-lying shafts are drained, from which they then the Sieve drum must be fed.
- EP 0 163 158 A2 describes a device for removing Screenings and / or screenings from flowing in a channel Known liquid.
- the device has an oblique in the Channels set, partially immersed in the liquid cylinder-shaped sieve grate.
- the sieve grid has a closed end wall in its upper area.
- An end wall provided on the upstream side is at least partially open.
- This cylinder jacket-shaped Siebrost is a screw conveyor with one driven screw conveyor and a stationary arranged Downstream housing with which the screenings and / or screenings is promoted diagonally upwards.
- the screw conveyor has an insertion funnel at its lower end.
- the drive shaft of the screw conveyor of the screw conveyor extends into the sieve grid and ends in one Drive arm, which in turn is connected to the sieve grate.
- the Siebrost is with its front wall provided in the upper area rotatably mounted on the housing of the screw conveyor.
- Baffles are provided on the inside of the sieve grate.
- There is a fixed detachment device on the outside of the sieve grate provided to that on the inside of the sieve grate detachable screenings or screenings and into the throw-in funnel discard the screw conveyor. To divide of sand mixtures in two fractions is this device not suitable.
- the invention has for its object, starting from the above outlined problem a device for processing a Sand mixture in at least one fine and one coarse fraction to further develop in such a way that the sand mixture is also made with it a shaft or other lower location in removed easily and in at least two fractions can be divided.
- this is the case with a device of the beginning described type achieved in that the drum of is penetrated by a drive shaft with which the sieve wall of Sieve drum is rotatably connected in its upper region that the drive shaft against the conveying direction of the sand mixture protrudes through the sieve drum with respect to the sieve drum and Part of an upstream screw conveyor with stationary housing and arranged on the drive shaft Conveying spiral is that the lower end wall of the screening drum rotatable on the housing of the screw conveyor is stored, and that on the inside of the sieve wall at least a thread-like baffle is provided.
- the entire length of the sieve drum is driven by a drive shaft interspersed.
- a Motor usually with the interposition of a reduction gear, attached, with which the drive shaft is driven becomes.
- the upper end wall of the screening drum is with the drive shaft non-rotatably connected, the upper end wall closed or can be partially open. Even through one Arrangement of arms can be achieved that the rotary drive from the drive shaft on the sieve drum and thus ultimately can also be transferred to the sieve wall.
- the sieve drum is also a screw conveyor upstream, the drive shaft for the screening drum also as the drive shaft of the screw conveyor serves. For this purpose the drive shaft protrudes over the front one lower end wall of the screening drum protruding beyond and is in provide this area with the conveyor helix.
- the funding spiral is in turn from a stationary housing of the screw conveyor surround. In this way there is only one drive motor for the sieve drum and the spiral of the screw conveyor required. Due to the difference in diameter between the screening drum and the housing of the screw conveyor there is a simple possibility the lower end wall of the screening drum on the housing of the Screw conveyor to be rotatably supported. That is at the same time ensured that the upper end of the screw conveyor to a certain extent with its stationary housing protrudes the interior of the sieve drum, so that the sand mixture can be easily and safely fed into the screening drum.
- the Housing of the screw conveyor is at its lower Open end. It can merge into a flange on which a pipe can be connected. This is especially so the case when the sand mixture is largely liquid becomes.
- the new device allows sands in a simple manner to be taken from deeper shafts or bunkers and to promote diagonally upwards to such a height that the educated Fractions in turn easily removed and further processed can be supplied. Still the device relatively simple and has only one only drive, which is also still protected at the upper end without being in with the sand mixture or the liquid To come into contact. That on the inside of the sieve drum arranged baffle, which is also multi-course or can be composed of parts arranged in regions, exerts an obliquely upward conveying effect on the sand mixture from, the components of the sand mixture in a rolling movement towards the inside of the sieve wall be transferred. This rolling movement makes it sticky Well broken up, which divides the two fractions is favored.
- the sand mixture is also partially, depending according to the speed at which the screening drum is driven is carried along by the screening drum and / or the baffle and limited upwards, from where it is then back in the interior the sieve drum downwards due to gravity falls. This is a corresponding breaking and cleaning effect connected.
- the fine fraction and liquid present pass through the openings in the sieve wall and are discharged together. Only the coarse fraction, consisting from coarse materials that exceed a certain size, are further promoted and separated from the Subtract fine fraction.
- Another advantage is that the inclined position of the axis of the drive shaft with which the Device is arranged, easily change and the application needs can be adjusted.
- the device can also be used Set up and operate the horizontally aligned axis. Also the sand mixture is safely into the interior of the sieve drum brought in.
- the thread-like baffles exercise a support function on the sand mixture and the forming Fractions. Change different angles of attack the operation of the device is not.
- the sieve drum advantageously has a much larger one Diameter than the screw conveyor. So that's it on the one hand possible a relatively large area of the sieve wall to make available and on the other hand the upstream To keep the screw conveyor small in diameter, to reduce the effort required for this. simultaneously there is the possibility of the housing of the screw conveyor as a bearing for the lower end wall of the Form the drum. In doing so, it becomes automatically Introducing the sand mixture into the interior of the sieve drum reached.
- the sieve drum is of a stationary arrangement surround that in the lower area a discharge nozzle for the Fine fraction and in the upper area a discharge nozzle for the Coarse fraction. This is not just the sieve drum housed safely, but the space between Sieve drum and housing can form at least one Fraction are used.
- the arrangement of the Housing housing additional elements, for example one or more splash bars, which are filled with nozzles could be.
- the stationary housing surrounds the sieve drum Distance and in an eccentric arrangement.
- a splash bar between the housing and the drum for removing sand mixture from the inside of the sieve drum intended.
- the splash bar is connected to a splash water supply connected so that from the outside of the screening drum Splashing water is sprayed on the inside of the Screen drum detaches adhering material and at least partially even in the interior of the drum, so that the Splashing water also serves as washing water for the sand mixture. This washing water occurs in the lower area of the sieve drum through the openings in the sieve wall and will subtracted together with the fine fraction.
- the screening drum can have at least one radially arranged outlet for the passage of the coarse fraction.
- the radially arranged So the outlet is in the area of the cylindrical jacket Screen wall provided. Since such an outlet is also circumferential the coarse fraction is discharged in batches. This has the advantage that the upper end wall of the screening drum as well as the stationary housing end wall could be.
- the drive shaft can be hollow over at least part of its length be formed in the area of the drum with radial Provide holes and connected to a spray water supply his. This shows an easy way, also from apply splashing water to the sand mixture and the inside Favoring or intensifying the rinsing and washing process.
- the upper end wall of the screening drum can have a first opening and the stationary arranged housing in the area of a housing end wall have a second opening through which the coarse fraction exits axially. So there is an axial exit realized, and the screen wall is at its full axial Length for dividing the sand mixture into fine and the coarse fraction used.
- the sieve wall of the sieve drum advantageously has a circular shape Openings with a diameter of 10 mm. This Determining the grain sizes of the two fractions makes sense when using the fine fraction in a sand washer of a sand fluidized bed are further cleaned and processed should. In this way, a coarse fraction of the Fluidised bed kept away. But it's easy to imagine that the openings in the sieve wall of the drum also with other dimensions can be chosen, if necessary to get a different application-specific distribution. It is also possible with the sieve wall of the sieve drum to provide different sized openings to in this way e.g. B. a division of the sand mixture to achieve in three or more fractions.

It are here through the penetrating the interior 7 of the screening drum 1 axial length of the drive shaft 10 and possibly over the Circumferentially distributed holes 33 provided by the spray water from the inside to the inside 8 of the sieve wall 5, on the Baffles 9 and those in the drum 1 Sand components is sprayed. This also makes the cleaning effect favored on the sand.
- the device works as follows. With the screw conveyor The generally contaminated sand mixture also becomes 18 from lower places, e.g. B. from a shaft, one Containers or the like, taken up and inclined in the conveying direction 22 promoted upwards. At the upper end of the housing 19 Sand mixture in the interior 7 of the rotatingly driven Screen drum 1 thrown off. The sand mixture falls in each area below the screen drum 1 and is by the rotation of the screen drum 1 from the screen wall 5 over the Scope taken and transported a certain distance upwards. From there it either falls down again or adheres the inside 8 of the sieve wall 5. Also the guide plates 9 perform a circulation and conveying function on the sand mixture.
- openings 6 in the sieve wall 5 are designed as bores with a diameter of 10 mm, sand components falling below this limit fall through through the openings 6. They slide on the wall of the Housing 2 down and get through the first discharge nozzle 26 as a purified fine fraction from the device. The Coarse fraction cannot pass through the openings 6, but is promoted upwards. It ultimately occurs through the opening 30 in the second discharge nozzle 28 over and is discharged according to arrow 29. Breaking up lumps of sand and cleaning the grains of sand is not just mechanical Rubbing, tumbling and falling from the inside 8 of the Sieve wall 5 causes, but essentially from the splash bar 31 supported. In addition, the cleaning effect still by injecting splash water from the inside over the hollow Drive shaft 10 are further supported.
