Description

a screw channel whose branches are partially or completely filled with a processing medium and parts 5.

At the left end of the container there is a vertical closed tray 6, the axis of which is located tangentially to the surface of the cylinder, on which lies the axis of the screw channel. Tray 6 communicates with the screw channel and is the loading position of the container.

At the right end of the container there is a horizontal closed tray 7, the axis of which is also located tangentially to the cylindrical surface on which lies the axis of the screw channel. Tray 7 is a continuation of the last turn of the screw channel and serves as the unloading position of the container. The bottom of the tray 7 is tangential to the top of the pipe 3. If necessary, for example, to increase separation efficiency or reduce the interaction between the parts, the tray 7 may be at a positive or negative angle to the horizon.

The upper part of the pipe at the site of the extreme right turn of the screw and the adjacent bottom of the tray 7 is provided with perforations. The size of the perforation holes is chosen such that the particles of the processing medium pass freely: through them, and the workpieces are delayed. Perforations on a slightly smaller area, if necessary, can be supplied with the upper sections of the pipe and one or two penultimate turns of the screw.

The space under the bottom of the tray 7 is bounded below by the inclined wall 8, which is also tangential to the pipe 3 and communicates with the pipe. The container wall in the upper part is provided with openings located along the container for supplying a liquid, which intensifies the processing process and removes wear products of the processing medium and the processing of parts. In the lower part of the left end there is an opening for draining the liquid.

The container 1 through the shock absorbers 9 rests on the inclined frame 10. The shock absorbers 11 serve to receive static axial forces. The frame 10 is installed with the possibility of rotation around the axis 12 by means of a screw 13 with a handwheel 14. Mashshna is installed on the base 15. At the ends of the container in bearings there are identical unbalances of 16 exciters, the shafts of which are aligned with the longitudinal axis of inertia of the container and through elastic couplings 17 are connected to the shafts of identical electric motor 18 mounted on the frame.

Due to the effect of self-synchronization, the unbalance of the vrah; they are synchronous, with a zero phase shift, due to which the container acquires circular

hesitation. Under the action of these oscillations, the machining feed, with the parts to be processed dispersed with it, acquires a circular motion around the axis of the container, which due to

the screw is converted into screw movement along the screw channel from the loading position to the unloading position. In the process of screw and oscillatory motion of the medium and parts, as a result of their interaction, the parts are machined. The processing speed depends on the amplitude and frequency of oscillations of the container (as they grow, the speed increases.), And the speed of movement of the medium and parts along the screw channel, moreover, on the angle of inclination of the container, with the increase of which it falls.

On reaching the last turn of the screw

the channel, the workpieces along tray 7 come out to the outside, and the processing medium through perforations in the tube 3 and at the bottom of the tray 7 is poured into the tube 3 and due to the inclination of the container and under the action of

circular oscillations are transported to the left end of the container, where the parts to be processed are loaded through the tray 6 (loading position). Together with the processing medium supplied through the pipe, they enter the screw channel.
