Abstract

This invention relates to the mining industry. The purpose of the invention is to increase the economy of the shelter by reducing the metal consumption and the volume of aspirated air. The shelter contains an internal K 1 placed inside a hollow outer casing (K) 4 with a perforated upper wall. (C) 8 connected to an aspiration funnel 5, a loading chute 6 with a chop plate 7 and face C. The end walls K 4 are aligned with the C funnel 5 with the formation in the lower part of the shelter of the annular chamber. The funnel 5 communicates with the chamber and is installed at an equal distance from the end walls of the shelter. With this arrangement, the shelter enters the funnel 5, the powdered air mainly from K 1 and partly from K 4. As a result, the removal of dust air does not come from the leaky area between K 4 and the conveyor belt, but through the suction surface formed by C 8, directly at the inlet of dusty air to K 1 from chute 6. The developed suction surface ensures the removal of air at low speeds and this prevents the entrapment of small fractions of the material being transferred into the suction network, 4 sludge. i (/

The invention relates to the mining industry and can be used in all sectors of the national economy, where the overloading of loose dust materials is used.

The purpose of the invention is to increase the economy of the shelter by reducing the metal consumption and the volume of aspirated air.

FIG. 1 shows the proposed shelter, isometric; in fig. 2 - the same, front view, section; in FIG. 3, the section AGA in FIG. 2, in FIG. 4 - the same, top view.

 The shelter for bulk material overloads includes an inner case .1 with an elastic partition .2 and a shutter 3 in the end wall removed from the trench, an outer case 4, an aspiration funnel 5, a loading chute 6 with a baffle plate 7. The aspiration funnel 5 is attached from above to the inner 1 and the outer 4 cowls, the walls of which are extensions of the walls of the outer shell. The upper wall 8 of the inner casing 1, which is located in the cavity of the aspiration funnel 5, is convex with perforation. In the side walls of the inner housing 1 there are triangular-shaped holes that are located between the elastic partition 2 and the shutter 3. The side walls of the inner 1 and outer 4 buildings, the end walls of the outer housing 4, the bottom wall of the loading chute 6, the elastic partition 2 and the curtain 3 form The bottom of the shelter is the annular chamber.

Shelter work is as follows.

Dusty airflow, ejected by falling material, is fed through the loading chute.6 into the inner case 1 of the shelter. Under the action of suction suction, this flow moves along the perforated convex top wall 8 of the inner housing 1 and enters the aspiration funnel 5 through the holes in it. Discharged through the leakage between the inner housing 1 and the conveyor belt 9, the dusty air through the annular chamber also enters the aspiration in

Ronku 5. At the same time, through leaks between the outer 1 case and the tape 9, outside, the minimum amount of air enters the shelter. With this design of the shelter in the aspiration funnel dusty air mainly flows from the inner shell of the shelter through the perforated surface and only partially from the outer shell. As a result, the removal of dusty air does not occur from the leakage area between the outer cover and the conveyor belt, but through the developed suction surface formed by the convex perforated upper wall of the inner case of the roof directly at the entrance of the dusty air from the groove to the inner cover. The developed surface-suction ensures the removal of air at low speeds and this prevents the entrainment of small fractions of the material being transferred into the suction network.

The location of the aspiration funnel at an equal distance from the lower edges of the end walls of the shelter ensures uniform external air inflow through leakages around the perimeter of the shelter in the amount that is minimally necessary to remove dust from the overload unit.

Invention Formula Shelter of bulk material transfer points, including an inner case with a perforated upper wall placed inside the hollow outer case, connected to an aspiration funnel, a loading chute with a baffle plate and end walls from. Characterized by the fact that, in order to increase the cost-effectiveness of the shelter by reducing the metal consumption and the volume of aspirated air, the walls of the outer casing are combined with the walls of the aspiration funnel to form an annular chamber in the lower part of the shelter, while the aspiration funnel communicates and set at equal distance from the end walls of the shelter. eight H FIG.
