SU559021A1 - Aspiraction shelter belt conveyor loading - Google Patents

Description

The invention relates to the mining industry and can be used to prevent dust formation in places of bulk material transfer.

A shelter is known to eat overloads of a dry gaternal containing a chute and an outer duct with sealing aprons, the E of which is an inner duct with a partition provided with a movable roller at the bottom.

The top cover of such a shelter is complete, single, and in the absence of additional sealing devices does not exclude the possibility of the expiration of dusty air through its leakiness.

Closest to the invention of the technical essence and the achieved result is the aspiration shelter of the belt conveyor loading places, including a box-shaped body with seals along its contour, suction air duct, charging chute and foam generator introduced into the upper part of the body. The shelter is attached to the upper and wider ventilated chambers connected to each other so that the upper ventilated chamber is connected to the drain window for the passage of dusty air, and the lower paci 0; io:; ena inside the casing.

This cover has low aspiration properties due to the uneven distribution of the flax, which leads to a large carry-over of the material and causes an additional load on the dust collecting devices.

The aim of the invention is to increase the efficiency of the aspiration and evenly distribute the foam on the material to be loaded - it is achieved that the housing of the proposed aspiration cover is equipped with a camera installed inside it with a gap relative to the side and end walls and fixed to its upper part so that the loading chute and the foam generator introduced in the first morning.

In addition, the Kafttepa is equipped with a foam distribution panel, mounted inside it in the middle part with a gap in relation to the face and side CTeifKaM and above the lower cut of the loading chute. The geometric center of the specified coincides with the longitudinal axis of the foam generator.

It is reasonable to carry out the foam distribution flap with a convex shape with convexity oriented to the foam generator, and in terms of the following: eG1; ellipse shape.

FIG. 1 shows the proposed aspiration shelter of the loading sites of the conveyor belt, a section; in fig. 2 - the same, top view (with the cover removed).

The aspiration shelter consists of a box-shaped body with seals 2 and its contour, a suction pipe 3, a loading chute 4 and a foam generator S. A chamber 6 is attached to the upper part of the body inside it with a gap relative to the side and end walls of the case.

In the middle part of chamber 6, the reinforcement of the protective board 7 is secured in a tight corner, the geometric center is connected with the longitudinal axis of the foam generator. To the bottom of the side walls of the chamber, which are facing across to the sheyer tape 8, there are sent aprons 9.

Bulk material enters the charging branch of 4 to 8. Under the convex foam guard 7, dust is accumulated, which from inside the scoop enters the chamber 6. From aqueous solutions of the first active substances in the foam generator 5, a high-fold foam is fed, which is supplied by a convex surface, and a foam surface is fed into the foam surface of the foam generator 5, which receives a high-fold foam, which is supplied by a convex surface. Fill the internal intensity of the chip between the slips and ribbons (. Dust is moistened and bound by foam, in addition to being fed to the twine tape 8 into the loaded material. Dust from the gap will fall ka kama in 6 and the housing 1 ioypocheno. Using vekoraofedelitelnogo

The shield also prevents premature release of the foam by the falling material.
