Abstract

This invention relates to the storage and discharge of bulk materials using bins. The aim of the invention is to improve the reliability and uniformity of unloading material from the hopper. The bunker device for bulk materials includes a body 1, a belt conveyor 3 and a tray 5 in the form of side 6 and end 7 walls hinged on rods 4 to the body 1. A vibrator 8 is mounted on the tray, and inside it are mounted flat inserts 9 expanding in the direction of movement of the conveyor 3, rigidly attached to the side walls 6 and inclined to the conveyor 3. In the process of unloading, the tray either spontaneously due to the connection with the material to be discharged, or using a vibrator 8 makes oscillatory movements that facilitate unloading the mat rial. 3 il.

Description

The invention relates to the storage and unloading of bulk materials using bins and can be used in food, construction, chemical and other sectors of the national economy.

The purpose of the invention is to increase the reliability and uniformity of unloading material from the hopper.

The use of flat inserts expanding in the direction of movement of the conveyor, rigidly attached to its side walls and inclined to the conveyor in the tray of the bunker device, ensures uniform release of material over the entire section of the bunker, spontaneous oscillation of the tray during unloading and disruption of internal connections in the slip material.

FIG. 1 shows a bunker for bulk materials, side cut; in fig. 2 - bunker tray, plan view; in fig. 3 - bunker device, cross, section.

The bunker device for bulk materials contains a vertical casing 1 with a bottom outlet 2. Under the casing a discharge belt casing 3 is mounted. Above the conveyor is mounted and pivotally suspended on rods x 4 to the casing 1 tray 5, made in the form of side lateral 6 and face 7 walls. A vibrator 8 is mounted on the tray, and flat inserts 9 are mounted inside the tray. The latter expand in the direction of movement of the conveyor 3, are rigidly attached to the side walls 6, and are inclined to the conveyor. Moreover, they are attached to the side walls with an elevation in the direction of movement of the conveyor. Above the conveyor belt is installed a relay 10 of the layer of material.

The bunker device for bulk materials works as follows.

With good material flowability, its release to the conveyor belt 3 from body 1 occurs by gravity. At the same time, the presence of flat inserts 9 ensures a uniform flow of material to the tape over the entire cross section of outlet 2. The mobility of the tray 5 relative to the housing 1 in combination with the expanding flat inserts promotes the oscillation of the tray relative to the conveyor 3 by adhering the tray to the material to be unloaded. When this movement of the tray leads to disruption of communication in the material between the material and the housing 1 or tray 5

In case of deterioration of the material flowability, the relay 10 triggers on the vibrator 8. Due to forced vibrations of the tray 5 and the housing 1, the material is fed to the conveyor 3, which triggers the relay 10 and turns off the vibrator 8. Invention form

Bunker device for bulk materials, containing a vertical case with a lower outlet hole mounted under the case a discharge belt conveyor mounted above the conveyor and hingedly suspended on rods to the case a tray made in the form of guiding side and end walls, and mounted on the tray a vibrator different from that that, in order to increase the reliability and uniformity of the material unloading, inside the tray are mounted flat inserts extending in the direction of movement of the conveyor, rigidly attached lennye to its inclined sidewalls and the conveyor, wherein the inserts are attached to the side walls with an elevation in the direction of conveyor movement.
