Description

The invention relates to machines for volumetric vibration treatment of parts using different types of filler. A device for continuous vibration processing of parts is known, which contains a vibrating container of a shchyndric shape, inside of which is a pipe with screw augers mounted on it, which has an aperture ij at one end. A disadvantage of the known device is the inadequate participation of the auger in the vibration treatment. The purpose of the invention is to increase the processing efficiency by eliminating closed zones in the container. This is achieved by the fact that in the proposed device the pipe is connected to the co-liner by an elastic connection and is mounted rotatably, the second end of the pipe and the screw blades are perforated, and the pipe ends are connected to a recirculation system. The pipe is equipped with a separating plug installed in the installation with the possibility of re-measuring ;. On the chart a schematic representation of the device described. The device contains a cylindrical container 1, which has end caps 2, upper cylinder 3 with a lid for loading, located on the top near the left end neck, and a lower neck with a gate for K1Sh unloading, located on the bottom of the container near the right end neck (not shown ). The container 1 rests on the springs 4. Inside the end necks 2 there are elastic hermetic ones in which, using the sub-cylinders of the hip units 6 and seals 7, are fixed the ends of the hollow shaft 8 with the screw 9 outside, connected with the V-belt drive 10. At the same time, the working volume occupied by the screw 9 with a wap is about half of the working volume of the container 1. It is possible to catch the ice cream.

There are ne (eporations 11, and the back shaft 8 near the CEU ends are perforated areas 1 2 that serve for the circulation of the working fluid. Inserted inside the hollow shaft 8; the plug 13 dp separates the left and

right perforated sections 12 of the hollow shaft B. The left end of the shaft 8 is connected to a hermetic anti-friction nozzle for sucking liquid from the container .1 ,. and the right end of the shaft with a sealed an-gafriktshmm nozzle For injecting a liquid under pressure into the container, ner 1 to the blade of the screw auger 9 and the walls (nozzles in the drawing are not shown)

.TO. to the end necks 2, bearing assemblies 14 are attached, in which the rear shafts 15 with unbalance weights 16 are mounted. The shafts 15 are connected by a V-belt transmission 17 with the respective drives.

Between the shaft 8 and the shaft 15 on the left and right of the container, install elastic anti-friction inserts 18 serving to prevent shock and seal the bearing: nodes 6 and 14, Ball 8 has reflective discs 19 installed at the beginning and at the end of the blade section separating the shchas from the longitudinal ends of the 2 ale container: Quieter anti-friction disks 20. Reflecting disks 19 with 2O disks serve to prevent distortions and to seal the rotating shaft 8,

In the drawing, indicated by arrows A The loading movement in the container caused by unbalanced loads 16, the arrows B - the load movement caused by the rotation of the shaft 8 with the screw 9, and the arrows B - movement of the working fluid caused by movements A and B and its own pressure in the perforated shaft cavity on the right.

The device works as follows.

The device is loaded.

The screw 9 and unbalance weights are driven to rotate. 16. The working fluid circulation system is connected. Movements A and B are arranged towards each other, with A around the periphery of the working cavity of container 1. Movement B can prevail over movement A, then the transported load abuts against the left end of the container, is pressed to the periphery of the container and is attached to the distance A. So kpc between container 1 m screw 9 has an elastic connection

144

I and the elasticity of the connection can be adjustable, the device oscillates like a two-mass system, and has the ability to operate in a resonant mode. During rotation, the shaft 8 with its blades 9 tends to transport the load along with the liquid forward, however, the liquid together with minor waste propels through the perforations and additionally intermixes and washes the load from the back of the blades, passes along and accumulates in its left end, goes out through the perforations 12 for cleaning and feeding back into the cavity of the shaft 8 on the right side. In this case, part of the working fluid moves along with the loading fluid near the container walls, reducing abrasive wear of the walls.

By rotating the screw in the vibrating container and by circulating the working fluid in the device, stagnant zones are eliminated and it is possible to vary the process conditions over a wide range, which makes it possible to use the device as a machine for continuous processing and to create production lines from the considered devices.
