FIG. 1 shows a line

in terms of; in fig. 2 - section aa on fig 0 1; in fig. 3 is a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 - section GG on fig „3„

The line consists of a container 1 (Fig. 1), elastically supported by means of springs 2 (Fig. 2) on a bed 3 (Fig. 1). The conveyor consists of two cavities 4 and 5 (Fig. 2), interconnected by a transition cavity 6 (Fig „1). The inner part of the container is lined with chemically resistant rubber 7 (Fig.). The container is equipped with an unbalance vibrator 8 connected by an elastic coupling 9 (Fig. 1), an electric motor 10, drain grids 11 (Fig „2), nozzles 12 (Fig. 1) connected by a flexible element 13 (Fig. 1) with a settling tank 14 , and the unloading device 15 is detailed (Fig. 1) with separable holes. The lacquer-settler 14 consists of two, parts 16 and 17 (Fig. 3) and is equipped with a diverting wall 18, longitudinal ribs 19 (Fig 3 and 5), a catcher 20 and a pump 21 (Fig. 3). The entry part of the device 15 for unloading parts (Fig. 4) is in the cavity 4 of the container 1, and the loading area 22 (Fig 1) is in the cavity 5 (Fig 2).

In the line along the process, screw installations 23 are installed (FIG. 4) with a drive 24 and drying 25 with a drive 26, interconnected by a gravity tray 27, and a container 28.

Lini works as follows. The container 1 filled with the processing medium, such as abrasive granules, is fed to the loading zone of the part 29 (individually or in batches). The container 1, when rotating the unbalanced vibrator 8, communicates the oscillator

nye movement. Under the action of the oscillating movement of the container, the loading medium (processing medium and parts) is associated with a rotational movement.

around the longitudinal axis of the container at different speeds, depending on the mass of the loading medium. From the tank 14, by means of the pump 21, the treatment fluid is supplied to the container through the flexible elements 13 and the nozzles 12. When the processing medium and the treatment fluid interact with parts, the latter are treated (cleaning the surface of parts from scale, rust, fatty contaminants, deburring and the defective surface layer).

Under the action of centrifugal forces arising during the rotation of the loading medium, the latter enters the unloading device 15, in which the processing medium separates from the parts due to the fact that the processing medium through the separation holes spills into the cavity 5 of the container 1, and the parts enter the screw installation sink type.

When the housing of the washing installation 23 is rotated, the parts are washed with water and advance along the longitudinal axis of the installation and, by means of a gravity tray 27, enter the screw-type drying installation 25.

When the casing of the drying unit is rotated, the parts are dried and, moving along the longitudinal axis of the unit, they fall into the container 28.

Since the loading medium 5 is continuously taken from the cavity 4 of the container 1, and the flow of it into the cavity 5, a height difference occurs in the loading medium, which, under the action of vibration, is located on the same level in two cavities, since during vibration the granulated processing the medium behaves like a pseudo-fluid. This contributes to the uniform circulation of the processing medium and parts from cavity 5 into cavity 4 through transition cavity 6 along the longitudinal axis of cavities 4 and 5. The addition of two movements (rotational - around the longitudinal axis of the container and translational - along the axis) causes the loading environment moves along a helical trajectory from the loading zone in cavity 5 to a device for unloading parts in cavity 4. i

During the operation of the line, the treatment fluid, which is fed into the container along with the treatment waste, through the drain grids 11 and the nozzle, is fed back to the flow section 16 of the sump tank 14 for settling. With the flow wall

18 liquid flows along the bottom of the flow section and goes to the longitudinal corridors formed by ribs

19 ° Here, the velocity of the fluid decreases, the fluid calms down, and its active sludge from heavy contaminants occurs.

Upon further movement of the liquid past the catcher 20, final sedimentation of light contamination products occurs. Then the liquid enters the second part 17 of the settling tank 14 through the septum, from which pump 21 again flows into the cavities 4 and 5 of the container 1 through the flexible element 13 and the nozzles 12 .

Such an implementation of the line allows to process parts of arbitrary configuration, since parts are processed in a loose state, to simplify the line design due to the lack of special mechanisms for transferring parts from one bath to another, to increase the working fluid life due to reliable sludge flow, to reduce consumption electricity, since the process of etching and degreasing occurs without the use of electrochemistry. In addition, such a mechanochemical effect on the surface of the part reduces the content of chemically active substances (acids and alkalis)

in the working fluid, which improves environmental parameters and reduces the production area of treatment facilities.
