Definitions

  • the invention relates to a sieve machine with a sieve frame or sieve box, a drive arrangement and a flexible sieve surface forming a sieve surface, which is fastened to sieve surface carriers arranged parallel to one another, which are connected to the sieve frame in a partially fixed and partially movable manner.
  • the sieve covering carriers are mounted such that they can be tilted to a limited extent about fixed axes in the sieving machine frame and are driven with alternating opposite tilting directions (DE-AS 1 275 339).
  • Such a screening machine in which all screen lining carriers are movably mounted, requires a not inconsiderable design effort for the storage and the drive of the screen lining carriers.
  • the sieve covering carriers are alternately firmly and movably connected to the sieve frame (DE-OS 34 11 719).
  • the movable sieve pad carriers are each connected to the pendulum mounted on the support structure (sieve frame), the Axis runs transversely to the direction of vibration of the support structure which can be set in vibration by a drive.
  • the inventive storage of the movable sieve plate carrier on the sieve frame with spring and / or link elements which make it possible to move the sieve plate carriers independently of one another and to drive them individually or in a spring mass system formed with the sieve frame, results in advantageous structures in addition to simple construction and good sieving performance Training opportunities of the screening machine according to the invention.
  • the screen box can be easily built and the drive of the entire screen box can be omitted.
  • the movable sieve plate carrier with the sieve frame is a 2-mass system.
  • the vibration behavior of the elastically supported sieve lining carrier can be determined in such a way that an intensive movement of the flexible sieve lining is generated, the oscillating systems expediently working somewhat below the resonance range.
  • the movable screen support can be arranged so that movements or vibrations in any direction are possible, for. B. horizontal, vertical, oblique or rotating.
  • the screen lining carriers can be arranged both in the cross-screen direction and in the longitudinal screen direction.
  • the screening machine can have an inclined or curved screen surface formed by the flexible screen covering.
  • the screen frame is expediently supported on springs.
  • the screen frame 1 and 2 has a.
  • Sieve frame or sieve box 1 which is expediently elastically supported on a foundation 2 by springs 3.
  • the screen frame 1 consists essentially of two side walls and suitable connecting elements to form a stiff Frame construction. Between the side cheeks are alternately fixed and movably connected to the sieve frame sieve support, which are designed as open or closed profile elements or the like ..
  • the sieve covering supports 4 are firmly connected to the sieve frame 1 or the side cheeks and can form part of the frame construction.
  • Movable screen lining supports 5 are connected to the screen frame 1 via spring and / or link elements (see FIG. 4), so that they can move relative to the screen frame 1, as indicated for example by arrows 6.
  • Imbalance drives which will be described later, are arranged on the movable sieve pad carriers 5, which set the movable sieve pad carriers in vibration and move them, for example, in the direction of the arrow.
  • the screen covering 7 is fastened to the screen covering supports 4 and 5 by known means.
  • the devices required for the feeding and removal of the screenings are known and are therefore not shown in detail.
  • the oscillating movement of the movable sieve pad carrier 5 or the sieve pad 7 causes intensive sieving while simultaneously promoting the material to be sieved on the inclined S sieve surface. 1 and 2, the oscillating movement is directed perpendicular to the screen covering 7 or to the screen surface.
  • the direction of movement of the movable sieve plate carrier can also lie in the plane of the sieve surface or at any angle to the sieve surface. Due to the movement of the screen pad carrier 5, the screen pad 7 is constantly tensioned and relaxed. This avoids clogging of the sieve openings, among other things.
  • the screen surface is inclined with respect to the horizontal.
  • the inclination of the sieve surface or the sieve box, the direction of oscillation as well as the number, the distance and the formation of the sieve support depend on the respective conditions of use.
  • FIG. 2 shows a screening machine with a "banana-shaped" curved screen surface, which works in the same way as the arrangement described in FIG. 1.
  • the curvature of the screen surface can be adapted to the operating conditions of the machine.
  • FIG. 3 shows a screening machine in which the screening box has a drive.
  • the screen box 1 is elastically supported on the foundation 2 via springs 3.
  • fixed sieve carrier 4 and movable sieve carrier 5 are provided in the sieve box.
  • the flexible screen covering 7 is connected in a known manner to the screen covering supports 4, 5.
  • a drive or vibration exciter 10 is arranged on the screening machine, which generates linear vibrations in the direction of the arrows 11, which pass through the center of gravity S of the vibrating system.
  • the vibrations have a horizontal and a vertical component. Since the screen surface of the machine runs horizontally, the oscillation movement must contain a horizontal component so that the material to be screened can be conveyed on the screen surface. In the example shown, the screenings are moved from left to right over the screen surface 7. With an inclined sieve surface, the oscillating movement of the sieve box 1 can also take place perpendicular to the sieve surface or the sieve covering 7.
  • a circular vibration exciter can also be used, which sets the screening machine in circular vibrations. In this case, the screen surface is arranged inclined to produce a conveying movement in the conveying direction.
  • the movable sieve covering supports 5 are supported in the desired direction of vibration, in the illustrated case in the vertical direction, via spring elements on the sieve frame 1 in such a way that they can perform oscillating movements when the sieve frame is suitably excited.
  • the sieve box 1 and the spring-mounted sieve plate carrier 5 form an oscillatory two-mass system in which the movable sieve plate carriers are excited to vibrate relative to the sieve box by the oscillating movements of the sieve box 1.
  • the system works in or slightly below the resonance range of the movable sieve plate carrier.
  • the vibrations can, as indicated by arrows 6, take place in the vertical direction.
  • the spring elements for connecting the movable screen lining carrier 5 to the screen box 1 are formed in a suitable manner and arranged on the screen box.
  • the feaer elements can also be designed and arranged in such a way that vibrations of the movable sieve support 5 result in a horizontal or oblique direction.
  • the movable sieve plate carriers are arranged in such a way that they perform an essentially linear swinging movement.
  • FIGS. 4 and 5 show the mounting or arrangement of a movable screen covering support 5 in the screen frame of a screening machine according to FIGS. 1 and 2 (FIG. 4: vertical section, FIG. 5: horizontal section).
  • Imbalance drives 20 are arranged on the two end faces of the screen lining carrier (FIG. 4: symbol representation, FIG. 5: schematic representation) ...
  • the screen support 5 is via spring elements 21 which, for. B. can be designed as coil springs, mounted on the screen frame 1.
  • the spring elements only serve to fix the screen lining carrier 5 in its rest position. They must be designed and arranged in such a way that they allow the movement of the screen lining carrier 5 in the desired direction of vibration. They are therefore soft in the direction of vibration and practically do not influence the vibration of the screen lining carrier in this direction.
  • elastic link elements, spring / link combinations with movable links or the like can also be provided. It only has to be ensured that the screen lining carrier 5 assumes a stable rest position and can move freely in the desired direction of oscillation.
  • the unbalance drives 20 are fastened in a suitable manner, for example on a bearing base or a bearing plate, on both end faces of the screen-pad carrier 5.
  • So-called self-synchronizing rotary exciters are used as unbalance drives.
  • Such pathogens are known. They exist e.g. B. each from a drive motor with two projecting shaft ends, on which unbalanced segments are arranged in the same angular position are not.
  • the two excitation drives on a screen pad carrier 5 are installed in such a way that their shafts run horizontally, parallel to one another and perpendicular to the longitudinal axis of the screen pad carrier.
  • the exciters synchronize themselves in a known manner, so that a linear oscillating movement of the screen pad carrier 5 occurs, in FIG. B. in the vertical direction, as indicated by arrows 8.
  • the axes of the two unbalance drives are always parallel to each other and in vertical planes perpendicular to the longitudinal direction of the screen pad carrier 5 . Dimensions. If the axes are arranged horizontally, as described in Fig. 4/5, a vertical movement or vibration occurs. If the axes of the unbalance drives are arranged vertically, there is a horizontal oscillating movement, if the arrangement is inclined, a movement with horizontal and vertical components is carried out in an inclined direction. In the screening machine according to the invention, any desired direction of movement of the movable screen lining carrier can therefore be generated by the arrangement of the unbalance drives.
  • the design and arrangement of the supporting spring and / or link elements for mounting the movable screen lining carrier is in each case adapted to the drive arrangement.
  • a single linear drive or exciter can also be used, which is to be arranged in the middle of the screen plate carrier.
  • This drive can directly, or z. B. can be connected via bracket elements to the screen covering support and arranged above or below the support.
  • FIG. 6 A further drive option for the movable screen lining support in screening machines according to FIGS. 1 and 2 with a swivel drive is shown in FIG. 6.
  • an unbalance drive designed as a torque exciter is arranged on an end face of a movable screen cover carrier 5 and, in conjunction with a corresponding mounting, generates pivoting or tilting movements of the movable screen cover carrier.
  • the Siebbelagieri 5 is mounted thereto for example via a link member or joint 22 so as to reciprocate in the direction of arrow 23 and reciprocate or pivot - or can execute tilting movements, wherein the screen lining 7 is excited alternately and relaxed.
  • the unbalance drive consists of a drive motor with two shaft ends on which unbalance segments are arranged. As indicated in the drawing, the unbalance segments are offset from one another in the circumferential direction by 180 degrees and form a so-called torque exciter 24 with the drive motor.
  • the drive shaft of the unbalance drive lies in a vertical plane perpendicular to the longitudinal axis of the screen lining carrier 5, in the exemplary embodiment in the paper plane or parallel to it. It can be horizontal as shown or in any other direction.
  • the torque exciter 24 is expediently arranged in such a way that its axis intersects the pivot axis of the screen lining carrier or the joint axis of the carrier.
  • the offset unbalance weights produce moments with an alternating direction about an axis perpendicular to the axis of the drive.
  • moments about the swivel axis or the joint 22 of the movable screen covering support 5 and thus swiveling movements of the support in the direction of the arrows 23 are generated.
  • the fixed and the movable sieve covering carriers 4/5 are arranged transversely to the longitudinal direction of the sieve, which lies in each case in the plane of the paper.
  • the screen covering supports can also be installed in the longitudinal direction of the screen.
