Definitions

  • the invention relates to a mobile classifying or screening device with a chassis and a frame arranged on the chassis for a classifying device with at least one screening surface for separating a fed-in screening material into at least two screening fractions, wherein the chassis has a longitudinal direction oriented in the direction of travel and a transverse direction oriented perpendicular to the longitudinal direction, and the frame comprises two lateral frame parts, each of which is formed from longitudinal beams running in the longitudinal direction, which are connected by webs running transversely to the longitudinal beams and comprise an uppermost longitudinal beam and a lowermost longitudinal beam, as well as at least two transverse beams running in the transverse direction, which connect the two lateral frame parts to one another in the region of their respective lowermost longitudinal beams, according to the preamble of claim 1.
  • a generic classifying or screening device which discloses a mobile classifying or screening device according to the preamble of claim 1, is known from CN 208213604 U
  • a device for the treatment of agricultural products was developed in the NL1017528 C2
  • Other classifying or screening devices are available in different designs, for example from the DE 298 02 416 U1 , WO 2019/076488 A1 , CN 204602610 U , US$3,909,401 , US$5,878,967 , US 5,421,108 A and the US 4,323,321 A and are used to separate screenings into screening fractions of different grain sizes using screening surfaces, screening in the true sense of the word, and sometimes also to separate them into fractions based on properties other than grain size, for example in terms of magnetic properties, which is referred to as classification.
  • classifying or screening devices that can be moved on roads are also designed in such a way that they have a chassis with a frame on which the functional components such as classifying devices, drive or body elements are arranged.
  • different device parts are lined up next to one another and connected to continuous conveyors in the form of conveyor belts.
  • the classifying device is usually also provided with a conveyor belt with which the screening material is fed to the classifying device, which limits the applicability of such devices to screening material with a grain size of less than 300 mm edge length.
  • the applicant is not aware of any design of mobile classifying or screening devices as heavy-duty screening systems that are also suitable for processing screening material with grain sizes of more than 300 mm edge length.
  • the applicant is not aware of any mobile classifying or screening devices that can be fed directly with a wheel loader, as the height of known classifying or screening devices in mobile design is too high for direct feeding with a wheel bearing.
  • Feeding known devices with an excavator would theoretically be conceivable, but in practical terms it is disadvantageous, as continuous feeding with an excavator in the range of the possible throughput of mobile classifying or screening devices of, for example, 200 t/h is not possible.
  • the classifying or screening device could therefore only be operated very inefficiently.
  • the aim of the invention is therefore to provide a classifying or screening device which, on the one hand, is designed as a mobile system suitable for transport on public roads and is therefore as compact as possible, and on the other hand enables higher material throughput than known designs of this type and can be used as a heavy-duty screening system.
  • Claim 1 relates to a mobile classifying or screening device with a chassis and a frame arranged on the chassis for a classifying device with at least one screening surface for separating a fed-in screening material into at least two screening fractions, wherein the chassis has a longitudinal direction oriented in the direction of travel and a transverse direction oriented perpendicular to the longitudinal direction, and the frame comprises two lateral frame parts, each of which is formed from longitudinal beams running in the longitudinal direction, which are connected by webs running transversely to the longitudinal beams and comprise an uppermost longitudinal beam and a lowermost longitudinal beam, as well as at least two transverse beams running in the transverse direction, which connect the two lateral frame parts to one another in the region of their respective lowermost longitudinal beams.
  • the classifying device is mounted on the longitudinal beams and that a storage and dosing unit for the screening material is provided, which is arranged next to the classifying device and mounted on the longitudinal beams and is designed as a trough-shaped feed trough with a substantially horizontal discharge direction for the screening material from the feed trough to the adjacent screening surface.
  • the design of the frame according to the invention replaces the chassis mentioned above and the body elements arranged on it and enables an extremely compact design.
  • the frame parts can initially be arranged so that their vertical projection is aligned with that of the crawler track, so that the maximum width of heavy goods vehicles permitted for road transport can be optimally utilized both in terms of the track width of the crawler undercarriage and the overall width of the device.
  • the screening area can be increased because its dimensions in the transverse direction can be maximized so that they lie within the range of this permitted maximum width.
  • a larger screening area compared to conventional designs also means a greater throughput of screening material and therefore a higher screening performance of the classifying or screening device.
  • the frame also forms a receiving space that can be optimally utilized not only in the transverse direction, but also in the vertical direction.
  • This is achieved according to the invention by means of the juxtaposition of the classifying device and the feeder trough and the essentially horizontal discharge direction for the screening material from the feeder trough to the adjacent screen surface, which makes it possible to achieve the mechanically excited conveying directions of the screening material in an essentially horizontal direction.
  • An essentially horizontal discharge direction of the screening material from the feeder trough to the screen surface means that although small drop heights can occur, the change in the height of the screening material in the transition from the feeder trough to the adjacent screen surface is negligible compared to the rest of the conveying path of the screening material from the feeder trough over the adjacent screen surface.
  • the feeder trough can also be fed directly with a wheel loader.
  • the screening material which is sometimes fed in bursts, is calmed down and fed to the classifying device in a metered manner.
  • the classifying device is designed as a known vibrating screen device with a directed, elliptical oscillation pattern, the screen surface of which is preferably aligned horizontally.
  • slightly rising or falling screen surfaces would also be conceivable.
  • the screen surfaces can be designed in different ways and, for example, be held in an oscillating frame that is elastically coupled to a screen box, which in turn is elastically supported on longitudinal beams of the frame parts.
  • the classifying device also preferably has two screen surfaces in screen decks lying one above the other, with the upper screen surface separating a coarse fraction with oversizes from a medium-coarse/finest screen fraction, and the lower screen surface separating the medium-coarse from the finest screen fraction.
  • the longitudinal beams run essentially horizontally or at least have horizontal sections and are used primarily to support the classifying device and the feed chute, while the upward and downward webs that connect the longitudinal beams lying one above the other mainly serve to stiffen the frame parts.
  • the openings in the frame parts framed by the longitudinal beams and the webs also serve to pass through transverse conveyors for separated screen fractions, as well as access openings for system components such as drive and/or hydraulic devices, as will be explained in more detail below.
  • the crossbars can also be positioned very advantageously.
  • the crossbars have a front crossbar located in front of the chassis in the longitudinal direction and an inner crossbar located behind the chassis in the longitudinal direction.
  • Cross beam whereby the inner cross beam is connected to the front cross beam by means of two longitudinal beams running in the longitudinal direction.
  • the terms "front” and “rear” are used here and in the following merely for linguistic differentiation and in particular do not refer to a direction of travel.
  • the two longitudinal beams delimit a receiving space between them, which represents the deepest receiving space of the entire device and can also be used to accommodate technical components in order to reduce the overall height. If the chassis is designed as a crawler chassis, for example, this receiving space can even be arranged between the two track drives of the crawler chassis.
  • This low-lying receiving space can preferably be used to arrange a continuous conveyor for discharging the finest screen fraction.
  • a fine fraction conveyor designed as a continuous conveyor is provided for a fine fraction forming the finest screen fraction, which has a horizontal conveyor section that runs between the two longitudinal beams and begins in an end region of the longitudinal beams facing the inner cross member and merges into an ascending conveyor section in an end region of the longitudinal beams facing the front cross member, the discharge end of which is above the front cross member.
  • the horizontal conveyor section thus runs within the device in the area close to the ground, since the finest screen fraction is obtained at the lowest point of the classifying device.
  • the fine fraction conveyor does not have to be dismantled or folded up, but can remain unchanged within the device.
  • the two frame parts each have a middle longitudinal beam running between the uppermost longitudinal beam and the lowermost longitudinal beam, which together with the respective lowermost longitudinal beam forms a discharge opening for the passage of continuous conveyors for coarser screen fractions running in the transverse direction.
  • the coarser screen fractions are obtained in a rear end of the device facing away from the front end of the device and discharged into lateral areas next to the device.
  • the discharge openings also represent assembly openings for the continuous conveyors, since the continuous conveyors for the coarser screen fractions protrude laterally from the device in operating condition and therefore have to be dismantled or folded in if the mobile classifying and screening device is to be transported. This dismantling is easy using the opening in the frame formed by the middle longitudinal beam and the lowermost longitudinal beam.
  • the classifying device is preferably mounted on the horizontally running, middle longitudinal beams, whereby it is supported on the middle longitudinal beams via an elastic bearing, as mentioned.
  • the storage and dosing unit it is proposed that it is mounted on the uppermost longitudinal beams, whereby it is also supported on the uppermost longitudinal beams via an elastic bearing.
  • the trough-shaped feed trough it is proposed that it be designed as a one-piece vibrating trough.
  • the term "one-piece” in this context means that the trough base and the wall parts of the feed trough are designed as one piece and are moved together, in contrast to a design in which only one trough base is moved within stationary wall parts.
  • the one-piece design and the movement of the entire feed trough enable the screening material to be discharged more quickly to the classifying device, which is made possible by its greater throughput.
  • This design also prevents the storage and dosing unit from becoming clogged, as often happens in known designs when only one trough base is moved within stationary wall parts.
  • the device in question as a classifying device for magnetically attractable, for example iron-containing, material components of the screening material
  • continuous conveyors be provided for discharging the screening fractions and magnetic separators arranged above the continuous conveyors for classifying magnetically attractable material components of the respective discharged screening fraction.
  • the magnetic separators can be attached to brackets, preferably adjustable in height, which protrude from the side frame parts.
  • the magnetic separators can also be attached directly to the continuous conveyors, preferably by means of adjustment devices with which the magnetic separators can be moved relative to the continuous conveyors from a transport position in which the magnetic separators essentially rest on the continuous conveyors, to a working position in which the magnetic separators are at an adjustable distance from the
  • the adjustment devices can be operated manually-mechanically, hydraulically or electro-mechanically and can be designed by means of a lever mechanism or sliding guides and the like.
  • the continuous conveyors In the transport position, the continuous conveyors can be dismantled or folded in with the magnetic separator attached to them.
  • the magnetic separators are arranged above the discharge ends of the continuous conveyors for the discharged sieve fractions and lift magnetically attractable material components from the respective discharged sieve fraction.
  • the height adjustability of the magnetic separators can be used to adjust to different magnetization properties of the magnetically attractable material components.
  • Layer height limiters or a layer height equalizer can also preferably be provided in order to optimally prepare the layer height of the discharged sieve fractions for magnetic separation and thus improve the separation of magnetically attractable material components.
  • One possible application is the classification of slag, where not only is there a separation into a very fine screen fraction, a medium-coarse screen fraction and a coarse fraction for different reuse options, but also the extraction of valuable materials, for example those containing iron. Since the continuous conveyors and the magnetic separators protrude from the side of the device when in operation, they must be dismantled or folded in before the mobile classification and screening device is transported.
  • a maintenance opening for drive and/or hydraulic devices be formed between the uppermost longitudinal beam and the lowermost longitudinal beam of a frame part.
  • the maintenance opening can also be used for replacing drive and/or hydraulic devices.
  • These openings can of course also be closed with removable covers to provide sound and dust protection. Furthermore, for reasons of sound insulation, it is advantageous to use noise-reducing materials on the noise-generating components of the device.
  • the longitudinal beams and/or the webs are designed, at least in sections, as hollow profiles for holding fuel and/or hydraulic fluid.
  • Their use as storage for fuel or hydraulic fluid means that voluminous tanks can be dispensed with, which in turn makes more compact designs possible.
  • the use of electric drives or hybrid drives is also possible.
  • the hydraulic fluid there is also the advantageous effect that hydraulic fluid that has heated up during operation can be cooled by storing it in the external longitudinal beams and/or webs.
  • the embodiment shown has a chassis that is designed as a crawler chassis with two chain drives 3. Furthermore, the storage and dosing unit 2 for the fed-in screening material SG, designed as a trough-shaped feed chute, can be seen, as well as the classifying device 1 arranged next to it.
  • the classifying device 1 is designed in the embodiment shown in such a way that it has two screen decks lying one above the other, which form two screen surfaces S1, S2.

  • a coarse fraction GF of the screening material SG reaches the wedge-shaped grate 4 and falls there onto a coarse fraction conveyor 5 located underneath, which is designed as a continuous conveyor that discharges the coarse fraction GF to the side of the device (see in particular also Fig.2 ).
  • Those parts of the screen fraction that are too large to fall through the wedge-shaped grate 4 are discarded at the rear end of the device as oversizes ÜG (see in particular Fig.1 and 3 ).
