Definitions

  • the device relates to the field of classification of bulk materials and can be used by processing enterprises.
  • a device for sorting bulk materials, which contains two oscillation generators mounted on the walls mounted on the walls of the housing, suspended horizontally on cable suspensions (see a. S. USSR N 264049, class B07B1 / 36, 1968).
  • the disadvantage of this device is that the vibrators create circular or very close vibrations to them, and the material on the screening surface is thrown up to move along the horizontal plane, which is associated with high energy costs.
  • the resonant wave classifier comprises a housing mounted on suspensions, inside of which a screening device in the form of a box with a screening surface in the form of a grid is suspended obliquely in the direction of movement of the material.
  • Oscillators operating in antiphase are fixed on the sides of the box at the same angle to its longitudinal axis, with the possibility of directing vibrations at the same angle to the longitudinal axis of the box in the plane of the screening surface.
  • oscillation generators are turned into antiphase mode. At the same time, they create a zigzag movement of the material without tossing along the screening surface. This reduces energy costs.
  • a disadvantage of the known device is its low efficiency, due to the formation of stagnant zones on the screening surface.
  • the technical result of the development is to increase the efficiency of the device.
  • the resonance-wave classifier comprising a housing, a sieving device installed with an inclination inside the housing and a pair of oscillation generators mounted on the walls of the housing and kinematically connected to the sieving device, is additionally equipped with frequency converters located outside the housing and electrically connected with oscillation generators, oscillation generators mounted on opposite walls of the housing, the screening device is made of a sifting grid and a resonant grating fixed under it and installed with an inclination towards one of the oscillation generators, and the kinematic connection of the sifting device with the oscillation generators is carried out by mechanical transmission of vibrations to the resonating grid.
  • the device is illustrated by a drawing.
  • Figure 1 schematically shows a General view of the classifier.
  • the resonant-wave classifier comprises a housing 1, a screening device 2 mounted with an inclination inside the housing, a loading hatch 3, located above the screening device, the outlet pipe of the finished product 4 and the screening outlet pipe 5, located under the screening device, oscillation generators 6 and 7, mounted on opposite walls of the housing, frequency converters 8 and 9, each of which is located outside the housing and is electrically connected to one from oscillation generators with the ability to control the frequency of the supply voltage.
  • the screening device consists of a screening grid 10 and a more massive resonant grating 11 fixed under it and is installed with an inclination in the direction of movement of the screened material to the screening outlet pipe, and the kinematic connection of the screening device with oscillation generators is carried out by mechanical transmission of vibrations to the resonating grid using levers 12 and 13.
  • the device operates as follows.
  • the housing 1 on the screening device 2 through the loading hatch 3 serves bulk material to be sorted into fractions.
  • the material falls on the screening grid 10 and presses it against the resonating grid 11.
  • the oscillation generators 6 and 7, respectively are supplied with a supply voltage.
  • Oscillators using levers 12 and 13 form waves of transverse vibrations in the resonant grating.
  • oscillation generators have different frequencies that are not multiple to each other.
  • the frequencies of the oscillation generators are tuned to resonance: one with odd tones of oscillations of the resonating grating, and the other with even ones. In this case, 40 and 60 Hz.
  • the final product of the desired fraction is discharged through the pipe 4, and the screening through the pipe 5.
  • the proposed resonant-wave classifier is characterized by high efficiency, simplicity of design, reliability and economy in operation, which provides a significant economic effect from its use.

Abstract

L'équipement se rapporte au domaine du tamisage de matériaux en vrac et peut être utilisé par des entreprises de retraitement. Le tamis à vibration par résonance comprend un corps (1), un dispositif de criblage (2) qui est monté au niveau d'une inclinaison à l'intérieur du corps, une buse d'admission (3) qui est disposée au-dessus du dispositif de criblage, une buse pour évacuer le produit fini (4) et une buse pour évacuer les produits de criblage (5), ces buses étant disposées sous le dispositif de criblage, des générateurs d'oscillations (6 et 7) fixés sur les parois opposées du corps et des convertisseurs de fréquence (8 et 9), chacun d'eux étant disposé à l'extérieur du corps et étant connecté électriquement à l'un des générateurs d'oscillations de sorte que la fréquence de la tension d'alimentation puisse être régulée. Le dispositif de criblage comprend un filet de criblage (10) et une grille à résonance (11) fixée sous ledit filet,et est monté au niveau d'une inclinaison dans le sens de déplacement du matériau subissant le criblage par rapport à la buse permettant d'évacuer les produits de criblage; et le dispositif de criblage est connecté de manière cinématique aux générateurs d'oscillations par liaison mécanique des oscillations sur la grille à résonance au moyen de leviers (12 et 13). Le tamis à vibration par résonance de l'invention est caractérisé par un rendement élevé, une structure simple, sa fiabilité et son économie de fonctionnement, ce qui rend son utilisation très économique.
