Description

The invention relates to the handling of bulk materials with the prevention of the ingress of dust and can be used in the mining, metallurgical and other sectors of the national economy.

The purpose of the invention is to reduce dust generation.

FIG. I and 2 shows the device, a general view.

The device for handling bulk materials comprises a loading tunnel 1 in which a loading container, for example a carriage 2, is placed and a container for loading, for example a movable channel 3.

In the end openings of the tunnel, elastic curtains 4 are installed, movable in a vertical plane and provided in the lower part with tubular elements 5 with end inlets and a longitudinal outlet slot directed inside the tunnel. At the corners of the tunnel are hollow columns 6 with air supply holes arranged in pairs. A dust receptacle 7 is installed at the place of dust generation, connected through air duct 8 to dust system 9 and communicating with aerodynamic channel 10 through hollow

columns 6. The elastic casing 11, attached to the gratings 12, forms with the bunker 13 an aerodynamic channel 10 under the loaded car.

The device works as follows.

When feeding into the tunnel 1 of the loading wagon 2, the movable chute 3 is positioned in the working direction along the movement of the material. Movable curtains 4, equipped with

the tubular elements 5 are lowered into the working position and their open apertures are aligned with the outlet openings of the air supplying hollow columns 6. Displaced by loose material the dusty

the air enters through the upper part and the leakiness of the car into the tunnel and is sucked in by the dust receiver 7 connected by the air duct 8 with the dust cleaning system 9. The main part of the air is directed through the air supply hollow columns into the aerodynamic channel 10 formed by the casing 11 of elastic material attached to the grilles , and the bunker 13 creates directional flows around the perimeter of the loaded wagon, and the rest of the air overlaps the end openings of the tonnes.
