Abstract

The invention can be used to dedust the process of loading bulk materials into rolling stock in iron ore dressing factories. The purpose of the invention is to reduce material losses during reloading by reducing its entrainment to the dust receiver. The device comprises a loading tunnel, a car 2, moving and fixed sections of the loading chute, a casing consisting of moving sections 5 and 6 with double walls, each of the sections being placed on a longitudinal frame 7 attached by hinges 8 to the walls of the loading tunnel, and having cutouts under the gutter The dusty air displaced by the bulk material from the carriage is concentrated in the casing and sent to the dust receptacle 10. 1 Cp.

the sliding sections 5 and 6 are double-walled, each of the sections being placed on a longitudinal frame 7 attached by hinges 8 to the walls of the loading tunnel, and has lines under

The invention relates to devices for handling and can be used in the mining industry to dedust the process of loading bulk materials, such as rolling stock, mainly in iron ore agglomeration factories.

The purpose of the invention is to reduce material losses during reloading by reducing its entrainment to the dust bin.

FIG. 1 shows the device, a general view; FIG. 2 shows section A-A in FIG. one.

The device includes a loading tunnel 1 in which a receiving container is placed, for example, a car 2 with a loading telescopic chute consisting of fixed sections 3 and movable sections 4.

In the loading tunnel above the car, there is a casing comprising the right 5 and left 6 cylindrical sections, each of which is mounted on a longitudinal frame 7 attached by hinges 8 to the walls of the loading tunnel, and each of the sleep sections is worn with a cable block drive 9.

In addition, the cylindrical sections 5 and 6 are made with dual walls and in the lower part they form an intake slot above the rail of the car, and in the upper part they are made with open apertures of movable sections 4 and connected through fixed sections 3 of the loading chute with dust collector 10 with a dust cleaning system 11.

The operation of the device is as follows.

When feeding into the tunnel 1 of the car 2, the movable sections 4 of the chute are lowered and, together with the fixed sections 3, are located in the working position, the movable cylindrical sections 5,6 mounted on the longitudinal frames 7 attached by hinges 8 to the walls of the loading tunnel are lowered to the car and open holes of their ow

placed with open apertures in moving sections 5 of the feed chute. The dusty air entrained in the flow of the material being discharged spreads along the bottom of the car, rises along the walls of the car and then enters the outer surface of the inner walls of the cylindrical sections. When flowing around a cylindrical surface due to centrifugal forces, the proc comes off, coagulation and the subsequent precipitation of dust particles on the bottom of the car comes off. Purified air enters the moving sections of the loading chute. At the same time, due to the vacuum in the cavity of the inner and outer walls of the sections along the outer surface, an upward flow of air is formed, which prevents the dusty air from the cavity of the Sun through the gap between the hood walls and the car. From the cavity between the walls of the cylindrical sections, air enters through the openings into the movable sections of the loading chute and mixes with the air from the cavity of the car cleared of large dust particles and is directed through the fixed sections of the loading chute into the dust receiver 10, from where it enters the dust-cleaning system 11 through the air ducts.
