Definitions

  • the invention relates to a sorting machine, in particular for the sorting of waste mixtures, in particular domestic waste, commercial waste, industrial waste, waste from demolitions, construction site waste, and wood waste or the like. According to the preamble of claim 1.
  • a sorting system for sorting valuable materials has become known from the earlier application of the applicant DE 34 15 090 A1.
  • a sorting machine contained therein consists of a vibrating conveyor belt, which is inclined transversely to the conveying direction and rises in the conveying direction, for separating body-shaped from flat sorting goods. A sieving process using meshes does not take place.
  • Drum sieves have the advantage that the material introduced is constantly thrown over one another by the rotary movement and thus pulled apart.
  • drum screens are not suitable for waste sorting, since the meshes also tend to clog with waste components.
  • the support and drive construction of drum screens requires axial space, which may be undesirable.
  • This device is not suitable for sorting waste since a separation process using a brush device is not possible.
  • the pocket shape of the conveyor belt only has the function of a holding device for stripping off the stalks which are beyond.
  • the invention has for its object to provide a sorting machine for waste processing, which above all allows a clog-free separation and sorting of waste mixtures, in particular household waste, commercial waste, industrial waste and the particularly difficult to process waste from demolition, construction site waste and waste from waste wood.
  • the invention first works on the principle of the divided flow in the longitudinal and transverse directions of a conveyor.
  • the mixture of recyclable materials to be sorted is placed on one side of an inclined conveyor belt and can pass the rotating conveyor belt transversely to the direction of travel by gravity and / or by vibration or vibration support.
  • Part of the mixture of recyclable materials falls into the sieve pockets attached to the sieve belt and is carried along in the longitudinal direction of the conveying device until the sieve pockets on the deflection roller tip over.
  • the sieve pockets therefore represent a perforated sieve, but with a limited drop height. This means that the entire screening system is practically free of blockages.
  • the screening device is designed in such a way that the conveyor belt in the area of the screening section is designed in the manner of a drum screen, ie the conveyor belt is guided in a circular, sagging manner in the manner of a cylinder jacket surface.
  • the drum-like effect of the normally flat transport screen belt is achieved in that the longitudinal axes of the deflecting rollers are positioned higher than the lowest point on the transport processing plane.
  • the inventive design of the sieve pockets is particularly advantageous in such a way that they open automatically during the deflection process via the upper deflection roller and this enables the sieve pocket to be emptied properly.
  • One back wall, common to two successive sieve pockets, is folded away from a pocket during the deflection process, so that an opening is created in this area.
  • the sorting machine (10) shown in FIG. 1 consists of a rotating, endless conveyor (11) with a lower deflection roller (12) and an upper deflection roller (13).
  • the conveying device is designed as a sieve conveyor belt (11) with sieve pockets (14) attached to it in a form arranged side by side and one behind the other. In Fig. 1, the sieve pockets are only shown schematically in sections on the sieve conveyor.
  • the sieve conveyor belt (11) is completely equipped with such sieve pockets on its transport surface.
  • the sieve machine (10) stands on a base frame (15), the sieve conveyor belt (11) being inclined at an angle ( ⁇ ) transversely to the direction of movement (16).
  • the longitudinal direction of the sieve conveyor belt is designated by reference symbol (16), and the transverse direction of the sieve conveyor belt by reference symbol (17).
  • the feed device (19) is shown in the form of a chute with oscillating drive (20) for the mixture of recyclable materials (32) to be applied to the sorting machine.
  • the discharge device (22) for the coarse material (29) is shown on the opposite low side edge (21).
  • the deflection rollers (12 and 13) for the sieve conveyor belt (11) are arranged in relation to the arrangement and length of the sieve conveyor belt in such a way that a structure in the manner of a drum sieve results in the region of the conveyor line for the goods to be transported.
  • the transport surface for the goods to be sorted therefore moves along a cylindrical surface (23).
  • the radius of curvature of this cylindrical surface is selected depending on the material to be treated.
  • the drum-like structure in the transport area is achieved by raising the longitudinal axes (24 or 25) of the deflection rollers (12 or 13) relative to the lowest point (26) on the screen conveyor belt.
  • the longitudinal axis (25) of the deflection roller (13) is arranged spatially higher than the longitudinal axis (24) of the deflection roller (12). This results in the steep rise of the sieve conveyor belt (11) and thus the drum-like structure for the constant circulation of the mixture of materials located thereon.
  • the drive of the deflection roller (13) and thus of the sieve conveyor belt (11) is identified by the drive motor (27), the drive being effected by means of a chain drive (43) which is covered by the conveyor belt (11).
  • the material is transported transversely to the longitudinal direction of the conveyor belt (16), ie in the transverse direction of the conveyor belt (17), by the inclination of the conveyor belt (11) by the angle ( ⁇ ).
  • the angle ( ⁇ ) is chosen in the size range between 5 to 20 ° similar to that of drum screens. However, it can also have different values depending on the material properties of the mixture of materials to be sorted. Material transport is therefore effected by gravity like a drum screen with material-circulating properties. Additionally or alternatively, an oscillating drive or a vibrating drive can also be provided for the sieve conveyor belt (11).
  • the sieve pockets (14) attached to the entire surface of the sieve conveyor belt (11) form a type of perforated sieve into which finer sieve material falls and is transported further in the longitudinal direction of the sieve conveyor belt (16). Only through the deflection process via the deflection roller (13) does the fine material (28) drop out as a separate sorting fraction. In contrast, the material that is too large for the sieve pockets (14) is transported further in the transverse direction of the sieve conveyor belt (17) and discharged as coarse material (29) in the discharge device (22). In order to ensure a sufficient residence time of the material mixture on the sieve conveyor belt (11), this must have a certain minimum width (B), which corresponds to the length of a drum sieve device including the supporting structure.
  • the width (B) is of the order of B ⁇ 4 m.
  • the sieve pockets (14) arranged on the sieve conveyor belt can either be all the same size or different in their pocket size. It would thus be possible to arrange coarser pockets in the area of the feed device (19) and finer sieve pockets in the area of the discharge device (22) in order to take into account the mixture of valuable substances which is constantly dissolving and separating during the sieving process. Fractions of different sizes could then be removed as coarse fraction (28a) and fine fraction (28b) in the area of the deflection roller (13).
  • the sieve pockets (14) can also be designed as longitudinal channels, with a longitudinal extension in the direction of the sieve conveyor belt transverse direction (17). For example, elongated goods such as poles, boards, etc. can be accommodated in these channels.
  • Fig. 1 is also a baffle (50) with a flexible curtain (51) z. B. from a chain curtain or the like. This baffle holds back material thrown back by the drum effect.
  • the longitudinal section shown in FIG. 2a through the longitudinal direction of the sieve conveyor belt clearly shows the structure and the effect of the sieve conveyor belt (11) in the manner of a drum sieve.
  • the cylindrical surface (23) extends almost around a full semicircle with the radius (r).
  • the transport direction of the sieve conveyor belt (11) in the longitudinal direction of the sieve conveyor belt is indicated by arrow (30).
  • Arrow (31) shows the circulation process of the material mixture (32), caused by the drum screen effect.
  • the fine material (28) is collected in the sieve pockets (14) and transported and deflected in the direction of arrow (33) to the upper deflection roller (13). In the area of the transport arrow (34), the fine material (28) tilts out of the rotating and opening sieve pockets (14).
  • the longitudinal axis (25) of the upper guide roller (13) is at a height (H1 ⁇ 2.1 to 2.4 m) above the longitudinal axis (24) of the guide roller (12).
  • This height (H1) determines the radius of curvature (r) of the drum-like sieve conveyor belt (11) in connection with the lateral length (L1 ⁇ 5.1 m).
  • the lowest point (26) of the sieve conveyor belt is approximately at the same height as the longitudinal axis (24) of the deflection roller (12).
  • the total length shown in Fig. 1 (L2) is approximately L2 ⁇ 7.2 m
  • the total height (H2) of the screen conveyor without support frame (15) is approximately H2 ⁇ 5.2 m.
  • FIG. 2b shows the view “X” according to FIG. 2a.
  • the material mixture (32) is then fed to the screen conveyor belt (11) at the lateral upper edge (18) (arrow 35) (see also FIG. 1).
  • the material mixture then migrates in through the inclination of the screen conveyor belt (11) and through further transport in the drum-like device Direction of the cross conveyor belt direction (17), the coarse material (29) being discharged on the edge (21) opposite the side edge (18) (arrow 29, 36) while the fine material is conveyed through the screen pockets (14) in the longitudinal conveyor belt direction (16) .
  • 2a (arrows 30, 33) are aligned in the longitudinal direction of the conveyor belt (16).
  • the lower (12) and the upper (13) deflection roller is shown schematically in Fig. 2b.
  • the dash-dotted line (37) in FIG. 2b corresponds to that in FIG. 2a and represents the outer radius of the sieve pockets running over the deflection rollers (12, 13).
  • the embodiment according to FIG. 3 shows a variant of the embodiment according to FIG. 2a. Due to a changed arrangement or shape of the lower deflection roller (12), an initially flat screen conveyor belt is set up in the area of (arrow 38). This may have the advantage that the mixture of recyclable materials and corresponding distribution on the conveyor belt can take place over a longer support width.
  • this screen conveyor belt works the same as shown in Fig. 1 or 2a.
  • the same positions are shown with the same reference numerals.
  • Each sieve pocket (14) consists of two side walls (39, 40) in the longitudinal direction of the conveyor belt (16) and two transverse walls (41, 42) in the transverse direction of the conveyor belt (17).
  • the longitudinal walls (39, 40) form with the transverse wall (41) a container closed on three sides, while the fourth side wall (42) each through the rear wall (41) next sieve pocket is formed.
  • the sieve pocket (14) is therefore formed, for example, by the walls (39 to 41) which are firmly connected to one another, while the transverse wall (42) is formed by the sieve pocket (14 ⁇ ) which follows.
  • the transverse wall (42) which is movable with respect to the sieve pocket (14) lies closely against the side walls (39, 40) and forms a closed container.
  • This condition exists in the area of the drum-like design with a radius of curvature (r).
  • the chain conveyor (43) shown schematically in FIG. 4a is therefore curved in the shape of the drum screen.
  • the chain conveyor (43) is deflected in the opposite direction than in the drum sieve area, so that the sieve pockets (14) open when the transverse wall (42) is pivoted away.
  • the sieve pocket volume is thus increased in the deflection area of the deflection roller (13), so that the contents can fall out even more easily.
  • the transverse walls (41, 42) are U-shaped in their area below the floor (44) Collection device (45) formed. Parts that slide down from the bottom of the sieve pocket (44) are therefore caught in the U-shaped recess (45) and cannot lead to the chain conveyor (43) becoming jammed.
  • the side walls (39, 40) or transverse walls (41, 42) can have additional angle plates (47) in their upper area. have, to stiffen the sieve pocket and to prevent slipping out of parts.
  • FIGS. 4a and 4b show an alternative embodiment of the sieve bag according to FIGS. 4a and 4b.
  • a flexible connecting band (48) is attached between the sieve pocket bottom (44) and the lower part of the foldable transverse wall (42).
  • the movable transverse wall (42) bears against the side walls (39, 40) in the area of the drum-shaped design or flat design of the screen conveyor belt (11). Only when the chain conveyor (43) moves around the deflection rollers (12, 13) does the sieve pocket (14) open and the transverse wall (42), which represents the rear wall to the next sieve pocket, pivots away from the sieve pocket.
  • the opening (49) thus created is closed by the flexible connecting band (48).
  • the invention is not restricted to the exemplary embodiments shown and described. Rather, it encompasses all professional training and further education without inventive step.
