Definitions
- the invention relates to a drum sieve machine with at least one rotating sieve drum, an inlet funnel, a drive and at least one collecting or removal device for removing the sieved material.
- Drum screening machines are known. They are used, for example, in processing and sorting plants to separate materials of different sizes or grain sizes. All in all, they offer a wide range of applications, for example in the screening and classification of compost, in residual waste treatment, for landfill dismantling, screening bark mulch, shredded material, waste wood cutting, tree cutting, mixed construction waste, building rubble, slag, gravel, earth or the like.
- the materials emerging from the sieve drum have grain sizes that can be assigned to about 90 percent of a certain defined size are.
- about 10 percent of this material accumulates as oversize, so that it is necessary to sieve it again or to feed the entire material of this fraction into a comminution system.
- This problem also occurs if stone grids on the inlet funnel prevent the entry of certain oversizes. This results in higher expenditure of working time and energy, which can also lead to the fact that the known drum screening machines are only used in pre-sorting or are only used for screening such goods in which the previously described deviations in grain size are negligibly small.
- this problem occurs, for example, in trees which have been shredded by means of roller crushers or shredders from clearings, old wood, railway sleepers or the like. But this problem is also relevant in the recycling of residual waste.
- the object of the invention is achieved by a drum screening machine consisting of at least one rotating screening drum, at least one drive for the screening drum, an inlet funnel and at least one collection or removal device for collecting or removal of the screened material, which is characterized in that before and / or at least one disc sieve is arranged on the drum sieve machine, which sieves a defined grain, in particular an oversize grain.
- a disc sieve By arranging a disc sieve in front of or on the drum sieving machine, the material emerging from the sieve drum at the end of the drum is determined as sieved material in a defined grain size.
- the passage width of the disc sieve now defines the largest grain size of the material to be mixed with sufficient accuracy.
- a further sieve fraction which is to be regarded as defined, is automatically obtained, which emerges from the end of the sieve drum.
- the disc sieve no longer allows the oversize to pass through, as is the case, for example, with the stone grids known to date is still the case.
- the invention then provides a drum screen machine which enables an additional defined fractionation of mixed goods. It is irrelevant whether one, two or three defined fractions have so far been made available by the respective drum screen machine. In each case, an additional, defined fraction is achieved in addition to the fractions made available so far. The technical and process engineering effort is reduced and energy saved. This advantage is particularly given by the arrangement of the disc screen directly in front of or on the drum screen machine.
- a further development of the drum sieve machine according to the invention is therefore characterized in that the disc sieve is arranged on the inlet funnel of the drum sieve machine.
- the advantage of the invention as described above is particularly evident. With a simple but effective technical measure, a drum screening machine with significantly improved performance properties is obtained.
- Another aspect of the invention relates to a drum sieve machine, as described above, which is characterized in that the disc sieve is designed to be folded away or pivoted away. Maintenance and cleaning work are made considerably easier. For example, blockages in the treatment of residual waste can be removed very easily after the disc screen has been swung away.
- the drum sieve machine is characterized by a common drive for the sieve drum and the disc sieve. This further reduces the expenditure on machinery and equipment.
- the drive for a sieve drum is usually dimensioned such that a disc sieve can also be driven by the drive of the sieve drum. In the event that the drive is not sufficiently dimensioned to drive both modules, the use of a larger drive is usually cheaper than the use of two separate drives.
- at least the drive for the screening drum of the drum screening machine is designed as a direct drive, preferably as a direct drive by means of a pinion. This saves expenditure on gearboxes. In modern drives, the speed control itself can be easily controlled.
- a further development of the invention is characterized in that the dimensions of the disc sieve are adapted to the size of the inlet funnel. This means that partial adjustments or covers in the filling area are no longer necessary.
- the disc sieve is arranged on the inlet funnel at an angle ( ⁇ ) that drops in the transport direction of the sieve drum.
- the drum screening machine according to the invention is also characterized in that a conveyor device, for example a conveyor belt or a chute, is provided for the removal of the defined oversize.
- a conveyor device for example a conveyor belt or a chute
- the oversize grain from the conveyor belt or the chute can then optionally be fed again into a comminution system via a further conveyor belt, before it is then again comminuted and fed to the drum screening machine.
- the conveyor device is constructed in several parts, in particular by being pivoted or pivoted away. In the case of mobile systems in particular, this is a measure which facilitates the transportation of the machine.
- a further advantage of the drum sieve machine according to the invention is indicated according to a further development in that the conveying direction of the conveying device for the oversize grain to be removed is opposite to the conveying direction of the sieved material.
- the fractionation of the mixed material is influenced in a positive way.
- the conveying device is arranged in front of the inlet funnel with reference to the conveying direction of the material to be sieved.
- the advantages of transporting such a machine occur here in the same way as described above.
- the disc sieve is designed to be exchangeable or removable, such that at least one stone grating, vibrating sieve or the like can be arranged instead of the disc sieve.
- This offers the advantage that the machine can be used in a known manner if, owing to the design of the material to be screened, the use of a disc screen is not necessary.
- the stone grating or the vibrating screen is also designed to be foldable or pivotable away. This also makes it easier to maintain or eliminate faults.
- a disk screen in particular for a drum screening machine as described above, consisting of at least two driven shafts provided with disks, the disks being offset or interdigitated on the various shafts, which is distinguished by this that the shafts are designed to be interchangeable.
- the interchangeability of the shafts enables the use of different shafts on or on a disc screen. So that's it also given that different shaft diameters, different disk diameters, different disk spacings on the shaft are made possible on a single base body of a disk sieve. Worn waves are easy to change. Retrofitting for different tasks is now very easy. The provision of differently equipped shafts enables universal use.
- Another aspect of the invention relates to a disk screen, which is characterized in that at least one of the disks is designed as a polygon deviating from the circular shape.
- the disks are designed to be interchangeable according to a further development of the disk sieve described above, in particular to be designed to be plugged or pushed onto the shaft. This makes it easy to replace worn windows. Disks of different shapes and sizes can also be positioned on a shaft.
- a further variant of the disc screen according to the invention, as described above, is characterized in that spacers are provided which can be pushed or pushed onto the shaft between the discs and which are held on the shaft by means of a tensioning device. This makes the exchange even more efficient.
- knobs It is also advantageous to provide at least one of the disks with at least one knob.
- the arrangement of knobs leads to a further improvement in the sieving result.
- compliance with a predetermined grain size is ensured even better.
- the knob is advantageously attached to the circumference of the disks.
- the disks have a plurality of bores arranged on the circumference, in each of which a knob can be detachably fixed or attached.
- the number, size and shape of the knobs can be varied, in particular designed to be exchangeable or interchangeable.
- the knobs have, for example, a rectangular, square, round or oval cross section.
- the shape of the knobs, as mentioned above, is in no way to be understood as limiting. It depends on the respective screening task.
- the invention also relates to a drum sieve machine with a disc sieve as described above.
- the invention also provides a processing or sorting system with at least one drum screen machine as described above and / or at least one disc screen as described above.
