SU1244347A2 - Shelter for loose material transloading area of belt conveyers - Google Patents

Description

The invention relates to the mining industry and can be used to control dust in places of gas-overload coal in mines.

The purpose of the invention is to prevent the accumulation inside the body of explosive concentrations of methane during gas overload coal.

Figure 1 shows the shelter of the place of transshipment of bulk materials on belt conveyors a general view; figure 2 - section aa in figure 1; on fig.Z - section BB in figure 1.

The device consists of a housing 1 with elastic seals 2 according to the parameter of its base. Inside to the side walls parallel to the top wall, the pallet 3 is rigidly fixed with a branch pipe 4, which is led out through a hole in the side wall of the housing. Pallet 3 divides the shelter into two channels - the top 5 and the bottom 6, communicating with each other. A piping 7 with sprinklers 8 and a louvered grill 9 is mounted in the upper channel, rigidly mounted on the pallet 3. The upper wall of the casing is provided with a window 10 with a louver dust separator 11. on the frame of the conveyor belt in the zone overload coal.

Shelter works as follows.

The air ejected by the falling coal enters the lower channel 6 and follows through the gap between the mechanical seal 2 into the upper channel 5 5 per. the account of the ejecting effect of dispersed water plumes formed by irrigators 8, to which; water is supplied through conduit 7 under a pressure of more than 1.0 MPa.

In the flares of dispersed water, dust is collected and then released as sludge in the louver grille 9. The sludge is collected in the pan 3 and is discharged out of the shelter through the nozzle 4.

Methane released from coal is concentrated in the upper layers of the air flow of the upper channel 5, since its density is about two times less than the density of air. The upper part of the air flow of the channel 5 with a high methane content is discharged through the window 10. The amount of air discharged from the shelter is adjusted by changing the installation angle of the gate. For additional dedusting of air exhausted from the cover, in window 10 a louver slider 11 is installed.

Replacing the missing volume of air under the cover in the volume removed through the window occurs due to leakage through leaks from the surrounding atmosphere in the zone of falling coal.
