Description

The invention relates to agricultural man-building, in particular to machines for post-harvest processing of grain and 1 crops, and can be used in chemical, mining industries for the separation of bulk materials but a complex of physical and mechanical properties.

The aim of the invention is to improve the quality of separation by ensuring the identity of the vibration modes over the entire area of the friction surfaces, reducing the separator's metal and metal intensity.

FIG. 1 shows a diagram of a vibration separator; in fig. 2 - the same, side view; pas figs. 3 - the same, top view.

The separator consists of a separating body in the form of friction surfaces 1 assembled in packages, mounted on vibrating tables 2 on elastic suspensions 3 on a supporting frame 4 with the formation of slopes inclined from the common axis of symmetry. Each ramp is mounted on the base frame 4 with the possibility of independent oscillations.

The vibrotables are driven into oscillatory motion by the vibration excitation mechanism from individual vibration exciters 5, receiving movement through a common counterdrive b, a V-belt drive 7 and a variator 8 from a drive (electric motor) 9. The counterdrive 6 is installed between the vibrating tables on a common frame. The longitudinal angle of inclination of the semiconductor of the surfaces is controlled by the mechanism 10, the transverse angle by the mechanism 11. The feed mixture is fed to the friction surfaces of each ramp with the help of an autonomous feed source 12 connected to the bunker by 13 elastic nipples 14. Section - 1, the mixture enters the receivers. Each vibration exciter is autonomously connected with the corresponding ramp and common drive with the possibility of synchronous oscillations and.

The separator works in the following way. The initial mixture from the hopper 13 through elastic paprubki 14 and the node 12 enters the friction surfaces and under the action of vibration effects is divided. Rounded smooth elastic particles are found in the lower parts of the shade section, in Bcpxinie, the receivers are flat, rough, less elastic particles.

In the pre: lagged separator, the packs of friconoHiHjix surfaces are spaced apart.

vibration vibrotoles, therefore vibrotables have a lower metal consumption, a much lower mass. In order to drive vibrofetters into oscillatory motion, small vibration exciters with electric motors of much lower power are required.

The installation of one common counter-exciter for two vibration exciters between vibro-thistles on a common frame also contributes to a decrease in the metal intensity of the separator. Such a counter-drive installation also ensures synchronization of the oscillation frequency of each vibrating table when it is changed using the variator.

The weight of the vibrating table of the known vibrating separator is 4500 N, the weight of the two vibrating tables of the proposed separator is 2000 N, i.e. the metal consumption of the proposed separator is much lower. The power consumption of the proposed separator is significantly lower: a 0.75 kW electric motor is sufficient to drive the vibrating tables in the proposed separator, and 1.5 kW in the known separator.

Placing the vibration exciters on each vibrating table of each slope of the friction surfaces ensures that the oscillations of all points of the friction surfaces are identical.
