Definitions

  • the present invention relates to a roller grate screening device for screening material according to the preamble of patent claim 1, comprising a plurality of mutually parallel, rotatably mounted in a frame, drivable waves. Between the waves of a section changeable gap widths are adjustable.
  • the gap widths are adjustable by a linear adjustment of the waves.
  • This adjustment usually leads to a displacement of the waves of this section in a horizontal plane or in an inclined plane which is spanned by the axes of further waves of the known devices.
  • Also in the horizontal there is an axial movement of the waves, as in DE 520 370 proposed.
  • roller grate screening devices are used for example in the sorting of waste materials and in the treatment of building materials containing sand, earth, stones of different sizes and the like. As a material.
  • the object is an adjustment of gap width means to implement as robust as possible executable and as easy to control Verstellmimik. Another advantage would be a further improvement of the screening performance.
  • the invention is based on the idea that an adjustment of the waves from the horizontal can also lead to the desired adjustment of the gap width.
  • this object is achieved in a generic roller grate screening device with the features of the characterizing part of claim 1, characterized in that the waves are received with adjustable gap width with bearings in the roller grate screening device, each with respect to the roller grate screening device on an arc section have movable center of rotation.
  • Inventive bearings of the shafts with adjustable gap width are movable relative to a frame of the roller grate screening device such that movement of the shafts from the otherwise horizontal plane of further waves of the roller grate screening device is achieved.
  • the frame in the second section on both sides of the movable shafts on eccentric discs are aligned with their axes parallel to the movable shafts about the center of the eccentric discs rotatably mounted in the frame.
  • the movable shafts are mounted eccentrically in the eccentric discs, so that the respective movable center of rotation of the bearings of the movable shafts is guided by the eccentric discs on a circular arc section.
  • roller grate screening device the one behind the other in the flow direction arranged eccentric discs on different Exzenterberichte, wherein distances between the centers of adjacent eccentric discs are the same.
  • the respective eccentric dimension of the eccentric disks increases in the direction of flow for each eccentric disk by an equal amount, so that a second gap width is obtained between each of the shafts in the second section.
  • roller grate screening device the movement of the turning centers on the bow sections by a single, mechanically coupled adjusting element, in particular a hydraulic cylinder, executable.
  • the adjusting element via an electro-hydraulic locking system is securable.
  • FIGS. 1 . 2 and 4a to 4c show the roller grate screening device 10 according to the invention in a single embodiment in plan view, side view of a first side and side views of a second side with schematically shown eccentric discs 30.
  • one of the eccentric discs 30 is shown separately in an axial section.
  • FIGS. 4a to 4c illustrate an adjustability of the movable shafts 24 by representations in the open position, middle position and closed position.
  • Fig. 1 the roller grate screening device 10 according to the invention for screening of material with nine mutually parallel, rotatably mounted in a frame 12 shafts 14, 24 is shown.
  • a first of the shafts 14 is partially covered on a task side 13 of adireblech. From the feed side 13, discontinued material moves in a flow direction 11 initially over five shafts 14 in a first section 16 and subsequently over four movable shafts 24 in a second section 26 during operation of the roller grate screening device 10.
  • a first gap 17 is formed between the shafts 14 of the first section 16. Between the shafts 14, 24 at the boundary of the first and second sections and between the movable shafts 24 of the second section 26, a second gap width 27 is adjustable.
  • All shafts 14, 24 are individually driven by means of drives 35. Their respective speed can be controlled by means of a controller.
  • the fixed position of the first turning centers 18 results from a bearing of the shafts 14 of the first section 16 directly in the frame 12 and its likewise stationary side walls.
  • the shafts 24 of the second section 26 are not rotatably mounted directly in the side walls of the frame 12, but in the eccentric discs 30.
  • the eccentric discs 30 are in turn connected at the same distance in the flow direction 11 in succession in their respective center rotatably connected to the respective side wall.
  • Each of the four successive eccentric discs 30 in the illustrations of Figures 2 and 4a to 4c has another eccentric measure. Seen in the flow direction 11 increases with each additional eccentric disc 30, the eccentric, so that it is at a rotation of the eccentric discs 30 for all eccentric discs 30 same angle to uniform second gap widths 27 comes.
  • the respective center of the eccentric disk 30 could be mounted rotatably in the respective side wall offset by a corresponding amount with respect to the horizontal. Then, in a position of the eccentric discs 30, a flat surface on the shafts 14, 24 of the roller grate screening device 10 would be achievable.
  • the structure of the eccentric disc 30 is particularly in Fig. 3 clearly visible. Radially outside the eccentric disc 30 is rotatably mounted in a bearing housing 36 of the frame 12. A spherical roller bearing 37 is accommodated eccentrically in a radially inner region of the eccentric disk 30. Axially remote from the respective shaft 24, the spherical roller bearing 37 is closed by a cover, wherein an adjusting arm 34 is designed to project in the radial direction in one piece with the cover. Axially facing the respective movable shaft 24, the spherical roller bearing 37 is fastened with a wiper cover 38 under customary cooperation with an eccentric wiper 39 against the eccentric disk 30.
  • FIGS. 4a to 4c it can be seen how when changing from an open position ( Fig. 4a ) about a middle position ( Fig. 4b ) in a closed position (4c), the second gap width 27a, 27b, 27c changed.
