Definitions

  • the invention relates to a system comprising a sieve body and an imbalance drive for vibrating sieve body of a screening machine with a conveying direction for the screenings, in particular mineral crushed materials such. Oil sands according to claim 1.
  • the DE 7811967 U1 is a vibration generating drive for processing machines, z. B. an elliptical vibrating screen to refer to the formation of true elliptical oscillations, with two oscillations generating these oscillators and synchronous with the same speed and counter rotating, different imbalance weights.
  • the imbalance weights are arranged on two continuous shafts, wherein a transmission in addition to the oscillating part of the machine, for. B. the screen box, is fixed.
  • the waves of the imbalance weights are connected by drive shafts or similar parts with the transmission outputs.
  • the unbalance weights carrying continuous waves are designed as rigid or propeller shafts.
  • a system according to the preamble of claim 1 is described with an imbalance drive for generating linear vibrations in large machine screens, wherein the vibration excitation is done by so-called double unbalance transmission.
  • a transmission comprises two shafts axially parallel mounted in a housing with imbalance disks located thereon, whose oppositely directed rotational movement is synchronized by a pair of gears within the housing.
  • the unit forms an imbalance module.
  • One of the two shafts protrudes from both sides of the housing, is driven on one side and can drive another such unbalance module on the other end of the shaft.
  • This unbalance drive contains to achieve sufficient vibration power six mounted on the screen body unbalance modules.
  • the invention is based on the object to provide a system with a strainer and an imbalance drive in the conveying direction of the material to be screened linear exerting strainer of a screening machine high throughput, which does not have these disadvantages, but whose mitschwingende with the strainer mass the sum of its imbalance masses exceeds as little as possible and its imbalance mass can be changed modularly.
  • a drive motor and a synchromesh gear are stationarily mounted next to the screen body, which do not resonate with it.
  • Each of the two output shafts of the synchronous transmission is assigned a single horizontal shaft which has unbalance elements and is connected to the output shaft by means of a torsionally rigid propeller shaft and arranged parallel to the axis to the adjacent shaft and transversely to the conveying direction of the screen body.
  • the unbalance elements are arranged directly on the shafts and in the horizontal direction between the side walls of the screen body, wherein the shafts are supported in the axial direction between the imbalance elements by means of bearing elements on a cross member connected to the side walls.
  • a torsionally rigid propeller shaft such as. B. a propeller shaft in operative connection.
  • the propeller shaft ends engage on the one hand at the free end of the output shaft of the synchronous transmission and on the other hand at the associated shaft end of the first shaft portion.
  • the invention particularly relates to the generation of linear vibrations of the screen body, but is not limited thereto.
  • the Figures 1 and 2 Principle sketches of a screening machine 1.
  • the screening machine 1 is driven by a drive motor 1 ', which is connected via a drive shaft 2 with a synchronous transmission 3.
  • the synchronous transmission 3 has two axis-parallel output shafts 4, 5.
  • the screening machine 1 is here only partially shown and includes a screen body 6, the indicated side walls 6 'has. Between the side walls 6 'of the screen body 6 are several imbalance modules 7, which are provided interchangeably in the region of trusses 21 between the side walls 6' of the screen body 6. In the region of the respective traverse 21, shaft sections 8 extend, which are arranged approximately in the same axis as the respective output shaft 4, 5 of the synchronous transmission 3.
  • the respective output shaft 4, 5 of the synchronous transmission 3 is connected to the first unbalance module 7.
  • the universal joint 10 engages the end region 11 of the first shaft section 8.
  • the individual shaft sections 8 are connected via torsionally rigid compensation couplings 12 with each other.
  • the reference numeral 13 the actual sieve is indicated.
  • FIGS. 3 and 4 show in various views a single imbalance module 7. It is a housing 14 shown, which includes a portion of the imbalance module 7. Each unbalance module 7 includes three spaced unbalance elements 15, 16, 17 which are mounted on a shaft portion 8. Between individual unbalance elements 15, 16, 17 bearing elements 18, 18 'are positioned. According to the invention, the unbalance elements 15, 17 are arranged outside the housing 14. Each imbalance module 7 includes attachment areas 22, by means of which it can be fastened to it in the area of the associated crossbar 21 (see also FIG Fig. 2 ).
  • FIG. 5 shows once again the schematic structure and the function of the unbalance drive. Shown are in an indicated form, the screening machine 1, the drive motor 1 ', the drive shaft 2 of the drive motor 1', the synchromesh 3 and its axially parallel output shafts 4, 5.
  • the synchromesh 3 includes at least one central gear 3 'and two drive gears 3 "
  • the side walls 6 ', the traverses 21 and imbalance modules 7 can be seen, which are each provided on a shaft section 8. Also visible are the joints 10 provided on the first imbalance module 7 and the rotationally rigid compensating couplings 12 arranged between the imbalance modules 7.
  • each unbalance module 7 three unbalance elements 15, 16, 17 are used, while at FIG. 6 in a non-inventive embodiment, only two unbalance elements 15, 16 are provided. This also requires a different bearing design. While in FIG. 5 two bearing elements 18, 18 'are provided, is in FIG. 6 only a single bearing element 18 is used.
  • the reduced space requirement allows (with the same outer dimensions) the adaptation of significantly increased "active" imbalance masses and significantly less resonant "dead mass”. This allows alternatively longer sieve trays, higher throughput or smaller screening machines at the same throughput. This reduces costs and, by minimizing the overall weight and external dimensions, also enables road transport from screening machines with higher throughput rates than before.
  • the system according to the invention is also readily applicable to conveyors, vibratory conveyors, Scrissalrinnen or similar devices.
