Abstract

The invention relates to a vibration technique, namely, to vibration devices of a monolayer transport of material, and can be used in the enrichment of minerals in the mining, chemical and other industries. The goal is to increase the performance of the feeder during the continuous transportation mode. Vibrating feeder contains mounted on a fixed base 1 on the shock absorbers (A) 2 oscillatory system. The latter includes a reactive frame 3, tray 4, electromagnetic vibration exciter 5 and springs (P) 6. P 6 is installed between frame 3 and tray 4 at an angle to the bottom 7 of tray 4. The axis of symmetry P 6 is horizontal. Installed A 2 on the sides of the frame 3 in the plane passing through the center of mass of the oscillatory system. The angle between this plane and the plane of the bottom 7 is equal to the angle of installation P 6 to the bottom 7 of the tray 4. Under these conditions of the arrangement of A2 and the oscillatory system, the maximum amplitude of the oscillations of the tray 4 arises in the absence of angular oscillation components. The transported material moves along the bottom 7 with the maximum possible speed in the continuous mode with given vibration parameters. This improves the performance of the vibrating feeder. 2 Il.

The invention relates to a vibration technique, namely to vibration devices of a multi-layer transport of material, and can be used in the enrichment of minerals in the mining, chemical and other industries.

The aim of the invention is to improve the performance of the feeder during unseparated mode of transportation.

FIG. 1 shows a vibrating feeder, a general view; in fig. 2 shows section A-A in FIG. one.

The vibrating feeder contains an oscillating system mounted on a fixed base 1 on the shock absorbers 2. The latter includes a reactive frame 3, tray 4, electromagnetic vibration exciter 5 and springs 6, which are installed between frame 3 and tray 4 at an angle to the bottom 7 of tray 4. The axes of symmetry of the springs 6 are horizontal. The shock absorbers 2 are installed on the sides of the reactive frame 3 in a plane passing through the center 8 of the mass of the oscillating system at an angle to the bottom 7 of the tray 4, equal to the angle of the springs to the bottom 7 of the tray 4, i.e. the angle of vibration p.

Vibrating feeder works as follows.

When applied to an electromagnetic vibration exciter 5, an alternating voltage in the magnetic cores of the electromagnet and the core produces a variable magnetic flux, which

generates a periodic force of attraction of the core to the electromagnet, as a result of which the tray makes translational oscillations. With the specified arrangement of the shock absorbers 2 and the oscillatory system, the maximum amplitude of the oscillations of the tray 4 arises in the absence of angular oscillation components. The transported material fed to the rear part of the tray 4, under the influence of vibrations, is laid out in a monolayer and moves along the bottom 7 of the tray 4 with the maximum possible speed under the given parameters of vibration. This improves the performance of the vibrating feeder.
