SU1370039A1 - Device for dedusting places of loading loose materials to hopper - Google Patents

Abstract

The invention can be used in the transshipment of bulk materials from hopper-type cars to hoppers. The purpose of the invention is to increase the effectiveness of dust removal. The device contains two plates 1 and 2, located above, the hopper 9 and covered with an elastic sheath 3, fixed with the lower end around the perimeter of the hopper above its upper edge. In the ventilation duct 8 of the bunker 9, a drive line ha 7 is located, carrying vertical supports 6 with a plate 2. The unloading car 15 is installed above the bunker 9, the drive 13 is turned on, the plates 1 and 2 are lifted and press the elastic casing 3 to the discharge hatches, forming the working valve cavity for sucking dust during unloading of the car. 1 hp ff.

The invention relates to a device for the dedusting of places for loading bulk materials and can be used for transferring bulk materials from hopper-type wagons to hoppers.

The purpose of the invention is to increase the efficiency of dust removal.

In Fig.1 schematically shows the proposed device, a General view; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 1.

The device contains two horizontally placed plates 1 and 2, covered with elastic sheath 3, consisting of two parts, one of which is fixed with the upper end around the second plate, and the lower end first, and the second part with the upper end of the blade the first slab, the lower one along the perimeter of the upper edge of the Bunker, above the entrance window of which the first slab is installed.

Rectangular plates 1 and 2 are connected by chains 5 and 4, which facilitate the movement of plates in a vertical plane. The top plate rests on vertical supports 6 with tension 7 placed in the ventilation duct 8 of the hopper 9. T he 7 seconds. using the shackle 10, it is connected by a flexible link 11 through 1 blocks 12 to the drive 13 (pneumatic cylinder). The bottom plate 2 is provided with 1D flaps connected to the surface of the hopper by chains 5.

The device works as follows.

Unloading wagon type 15 Hog35

the bulk material, and the flaps 14, turning at the points of attachment O, due to the tension of the chains 5 close the opening between the hatches.

Then a fan (not shown) is turned on, the hatches of the cars are opened and the bulk material is unloaded. The entraining dust, when unloaded, is sucked off by a fan from the cavity formed by the elastic casing 3 and the ventilation duct 8.

Claims (2)

1. A device for dedusting places for loading bulk materials into a bunker, containing a sealing element fixed by a bottom end around the perimeter of the upper edge of the bunker, a mechanism for driving its movement with a power cylinder and a plate with openings for passing granular material and air horizontally above the entrance window of the bunker characterized in that, in order to increase the efficiency of dedusting, it is provided with a second plate, horizontally and symmetrically placed above the first with the possibility of vertical movement tnositelno it, closed resilient shell fixed on the upper end of the perimeter of the second plate, and the lower - first, the drive mechanism includes a vertical rack fixed to the lower ends of horizontal T n kinematically associated with the power cylinder and installed the lane is mounted above the bunker with the help of a traction winch and a tower in the bunker 16. The drive (pneumatic tubular) is activated, the working piston of which is connected by a flexible link (for example, a chain or cable) with a link of 10 tons 7, Zannaya with the top plate 1 using the racks 6. At the same time, plates 1 and 2, lifting, tightly extend the elastic sheath to the ends of the unloading hatches of hopper-type cars, thus forming a working ventilation cavity for sucking the pier during the unloading process. 45 50 gate-forward movement in the vertical plane, the second plate is attached to the upper ends of the mentioned racks, and the sealing element., is made in the form of a closed elastic sheath, the upper end of the first plate fixed along the perimeter.   2. The device according to claim 1, wherein the supply is, but with flaps, located between the peripheral openings of the first plate with its front sides. g 5 o five the bulk material, and the flaps 14, turning at the points of attachment O, due to the tension of the chains 5 close the opening between the hatches. Then a fan (not shown) is turned on, the hatches of the cars are opened and the bulk material is unloaded. The entraining dust, when unloaded, is sucked off by a fan from the cavity formed by the elastic casing 3 and the ventilation duct 8. Invention Formula 1. A device for dedusting places for loading bulk materials into a bunker, containing a sealing element fixed by a bottom end around the perimeter of the upper edge of the bunker, a mechanism for driving its movement with a power cylinder and a plate with openings for passing granular material and air horizontally above the entrance window of the bunker characterized in that, in order to increase the efficiency of dedusting, it is provided with a second plate, horizontally and symmetrically placed above the first with the possibility of vertical movement tnositelno it, closed resilient shell fixed on the upper end of the perimeter of the second plate, and the lower - first, the drive mechanism includes a vertical rack fixed to the lower ends of horizontal T n kinematically associated with the power cylinder and installed gate-forward movement in the vertical plane, the second plate is attached to the upper ends of the mentioned racks, and the sealing element., is made in the form of a closed elastic sheath, the upper end of the first plate fixed along the perimeter.   2. The device according to claim 1, wherein the supply is, but with flaps, located between the peripheral openings of the first plate with its front sides. Juz
