Abstract

The invention relates to the field of mining, namely to the means of providing ore production, and can be used to clean the walls of the bins from freeze bulk material. The goal is to increase the reliability of the device. The plates are installed in the upper part of the niche, made in the inclined walls of the outlet neck 2. The plates are moved from the initial state to the inside of the niches and back, causing the collapse of both the stagnant zone of the material in the neck 2 and the resulting vault. 1 h. item f-ly, 2 ill.

Description

1

The invention relates to the field of mining, namely to the means of providing ore production, and can be used to clean the walls of the bins from freeze bulk material.

The device works as follows.

In the initial state, the plates 7-10 are installed in a horizontal position, forming a flat plane of inclined

The aim of the invention is to increase the 5 walls of the outlet neck 2. Loose workmanship.

The proposed design produces the initial movement of the plates, not inserting them into the material of the stagnant zone, but lowering them into the hollow niches, while significantly increasing the flow area of the outlet throat. The backward movement of the plates occurs with penetration into the collapsed material, but under more lightened conditions, since the material collapses and moves due to the collapse.

FIG. 1 shows schematically a bunker device, a cross-section; in fig. 2 - the same, top view.

The device comprises a housing 1 with an outlet neck 2 with walls inclined toward the outflow. On each inclined wall with diametrically opposite sides, rectangular niches 3, 4 and 5, 6 are made. Each niche 3-6 is open in the lower part towards the expiration of the material. Plates 7-10 are hinged at the neck to induce the outflow of material, with each plate located in the upper part of one of the niches. As a drive, an eccentric vibrator 11, 12 can be used.

In order to reduce the failure of the fine fraction through the gap between the plates and the inclined walls in the niche cavity, it is possible to install elas around the perimeter of the plates.

The material is loaded into the housing 1 and through the outlet neck 2 by gravity enters the unloading.

In case of stagnation

10 or the arch of the bulk material, as well as the technological prevention of arch formation, include the actuators And and 12 plates. Plates 7-10, hinged in niches 3-6, are lowered into them, breaking the stagnant zone. The collapse of the stagnation zone deprives the base of the base, with the result that its collapse occurs. The plates 7-10 are reversed with the introduction of the outlet neck 2 into the collapsed material, however, with its significantly weakened resistance to sm due to its loosening during the collapse, its state of mobility.

Swing plates 7-10 can be performed continuously, periodically or one-time in the form of one cycle.
