SU435173A1 - DEVICE FOR TRANSPORTATION BY SELF-CUTTERS OF BULK MATERIALS - Google Patents

Description

one

This invention relates to a T1 transport of bulk materials (e.g., ground salt), in particular to devices for transporting them by gravity.

BACKGROUND OF THE INVENTION There are devices for spontaneous transportation of bulk materials containing an inclined chute, hermetically adjacent to the hopper and provided in the lower part with a covering casing.

The disadvantage of these devices is the release of a significant amount of dusty air formed at the place of unloading and entering the production atmosphere during transportation of bulk materials prone to dust formation.

In order to reduce the amount of dust-laden air coming out of the leaks of the harness housing, the chute is divided over its entire length by a partition located parallel to the chute bottom and having air holes in the upper part.

To create a gap between the partition and the transported material, in the upper part of the chute, a gate is installed perpendicular to its axis.

The drawing shows the proposed device.

Inclined estrus 1 in the upper part is hermetically attached to the hopper 2, and in the lower part has a covering cover

3. The heat pipe 1 is divided over its entire length by a partition 4 located parallel to the bottom of the chute. The partition 4 has in its upper part of the hole 5 of a slit-like or round shape for the passage of air. A gate valve 6 is installed at the top of the chute, which has the ability to move perpendicular to its axis.

The device works as follows. Due to the rarefaction resulting from

the movement of material in the upper part of the chute 1, the dusty air is sucked up through the cavity formed by the partition 4 and the upper side of the chute 1 to the holes 5 in the partition 4. The absence of perforation in the lower

part of the septum contributes to an increase in the efficiency of suction of dusty air, since the turbulence of the air flow in the lower part of the cavity is eliminated. The gateway 6 creates a gap between the partition 4 and the moving material, which makes it possible to more effectively use the ejection properties of the material for suction of dusty air.
