Description

Containers 3 are installed in parallel by elastic resistors 2. Under each of the containers there are vibration exciters 4 driven by engines 5 through elastic sleeves 6. The vibration exciters are kinematically connected by means of a chain gear 7. The right open ends of the containers are connected by a connecting element 8 sec. 9 and a lattice partition 10. A vertical lattice partition 10 serves to block the load flow consisting of the working medium 11 and the workpieces 12, and is located one side of the x walls of the container and their adjacent wall 13. The vibration machine is installed on the foundation with shock absorbers 14. A casing 15 is attached to the right open ends of the containers, in which a connecting element 17 equipped with an elastic element 18 is resiliently installed by means of an elastic system 16 of adjustable stiffness connecting elements are lined with wear-resistant rubber 19..

The elastic system 16, by means of which the left connecting element 17 is installed in the casing 15, consists of springs 2 O attached to the casing and the connecting element by means of cups 21. Between the coils of the springs there are rubber-cord hoses 22 having longitudinal grooves Zany with a source of adjustable air pressure.

The described vibration installation operates as follows. The kinematically coupled vibration exciters 4 communicate oscillatory movements in the vertical plane to the containers 3. Under the action of vibration and variable accelerations, the loading makes a rotational movement opposite to the rotation of the vibration exciter. Due to the uneven loading pressure on the side walls of the containers (due to the load of the working load on one of the walls of the container, its level is opposite to the opposite wall) through the connecting element 8, sifting through the separation grid 9 and the lattice partition 10, the load from the left container flows into the right one (see Fig. 5). In the right part of the right container you create} mc: load excess, that is, the drop height of the load. Due to the fact that the loading under the action of vibration acquires the properties of fluidity, it moves along a closed spiral path to the left side of the right container (see Fig. 2). The connecting element 17, elastically mounted on the containers and connecting them, oscillates in antiphase to the oscillating containers. Finding in it, the download will receive €.

rotational movement opposite to the direction of rotation of the load in the containers. As a consequence, the loading pressure on the left wall of the connecting element 17 5 more than the right (see Fig. 6). Thus, in the left container a drop height of load is created, while in the left part of the load level is more than the right one (see Fig. 2).

Due to the formation of different levels of loading in containers, the latter, under the action of vibration along a helical spiral, begins to move through the containers (see Fig. 2). To the left of the lattice partition 10, workpieces 12 are continuously fed into the container, which, together with the working medium 11, move along the containers, being processed. Having passed both containers, they fall on the separation grid 9 and are transported through it into a container of finished products (not shown). The working medium, sifting through the separation grid and the lattice partition, passes

5 again into the right container, moving along a closed spiral path. By changing the phase rotation of the kinematically connected vibration exciters 4 (changing their angle of matching) and changing the rigidity of the elastic system 16 of the connecting element 17, it is easy to achieve an increase in the difference in loading heights in containers and an increase in its speed

r transport over the connecting element 17, and thereby regulate the speed of transporting the load along the containers, without changing the processing mode.

Such a design

The vibration unit 0 allows smoothly and widely controlling the movement speed of the load in the containers and optimizing the process of vibration treatment. The vibration machine offered is a universal one and can operate in automatic mode.
