SU777238A1 - Shelter for reloading loose materials on belt conveyers - Google Patents

Description

The invention relates to the mining industry and can be used to control dust at the points of transshipment of bulk materials when reloading the rock mass from conveyor to conveyor in 5 mining workings.

It is known that the shelter of the bulk materials transshipment point · on belt conveyors is known, consisting of a housing, gaskets and duct systems, equipped with 10 trapezoidal plates rigidly attached to the side walls inside the housing and located in a plane parallel to its upper base [1] · 15

A disadvantage of the known device is that it does not allow the purification of aspirated air.

Closest to this invention is an aspiration shelter for a bulk material handling unit, including a housing, sealing aprons, a dust precipitation device made in the form of diamond-shaped spirals and sprinklers [2]. ' ₂ 5

A disadvantage of the known device is the low efficiency of dedusting of air, as well as waterlogging of the transported material with a liquid irrigating dust. thirty

The aim of the invention is to increase the efficiency of dedusting and preventing overmoistening of the transported material.

This is achieved by the fact that the dust precipitation device is made in the form of a louvre lattice mounted on a pallet rigidly attached to the side walls of the housing and having a drain pipe, while this pallet is placed parallel to the upper wall of the housing in such a way that it divides the shelter into two channels - upper and lower communicating with each other in the zones of dust formation and dust extraction, and the sprinklers are installed in the upper channel, and the drain pipe is removed outside the housing through an opening that is made in the side wall of the housing a.

In FIG. 1 shows the shelter of the place of transshipment of bulk materials on conveyor belts, general view; in FIG. 2 - section A — A of FIG. 1; in FIG. 3 - section B — B of FIG. 1.

The device consists of a housing 1 with elastic seals 2 around the perimeter of its base. Inside, to the side walls parallel to the lid, a pallet 3 is rigidly attached with a nozzle 4 brought out through an opening that is made in the side wall of the housing.

Pallet 3 divides the shelter into two channels - the upper 5 and lower 6, communicating with each other. In the upper channel there is a pipeline 7 with sprinklers 8 and a louvre grille 9, rigidly mounted on a pallet 3.

The shelter is rigidly mounted on the frame of the conveyor belt in the area of loading bulk material.

The air ejected by the falling material enters the lower channel 6 and follows through the gap between the tray 3 and the mechanical seal 2 into the upper channel 5 due to the ejecting action of the dispersed water flames formed by the sprinklers 8, to which water is supplied through pipeline 7 under a pressure of 10-15 atm.

- Dusty air passing through the louvre grille 9, is cleaned of dust and goes into the zone of falling bulk material.

The dust settled on the louvre grate 9 is washed off by the liquid supplied from the sprinklers 8 and flows into the pan 3, from where it is discharged outside the housing of the shelter through the drain pipe 4.

Claims (2)

Pallet 3 divides the shelter into two channels, the upper 5 and the lower 6, communicating with each other. A pipeline 7 with sprinklers 8 and a louvered grill 9 are installed in the upper channel, rigidly mounted on the pallet 3. The shelter is rigidly fixed on the frame of the belt conveyor in the zone of bulk material overload. The air ejected by the falling material enters the lower channel 6 and flows through the gap between the tray 3 and the mechanical seal 2 into the upper channel 5 due to the ejecting effect of dispersed water plumes formed by the irio bodies 5, to which water is supplied pipeline 7 under pressure of 10-15 atm. - The dusty air, the passage through the louvered grille 9, is cleaned of dust and goes into the zone of falling of the friable mother-20 ala. The dust that has settled on the louvre grille 9 is washed off with liquid supplied from the sprinklers 8 and flows into the sump 3, from where it is discharged through the drain nipple 4 to the pre-25 cover housing case. . Claim 1. Shelter of bulk solids transshipment point on conveyor belts, 30 / L. 5 comprising a housing with a dust precipitation device and sprinklers and elastic seals, characterized in that, in order to increase the efficiency of air dedusting and prevent overwetting of the transported material, the dust precipitation device is made in the form of a louvered grille mounted on a pallet rigidly attached to the side walls of the housing and having the drain pipe, while the specified pallet is placed parallel to the upper wall of the case in such a way that divides the shelter into two channels - upper and lower, the message They are interconnected in the areas of dusting and dust extraction, and the sprinklers are installed in the upper channel. 2. Shelter according to Claim. 1, characterized in that the drain pipe is led out of the housing through an opening which is made in the side wall of the housing.
