Description

one

The invention relates to the mining industry and can be used for averaging bulk materials.

A device for averaging bulk materials is known, which consists of multi-compartment bins with discharge out-section bins with discharge devices that provide simultaneous unloading of all sections of the bunker filled with a variety of material 1.

The drawbacks of the device are the necessity of preliminary separation of the bulk material according to the qualitative characteristics, as well as an insufficient degree of attainable averaging.

A device for averaging bulk materials is also known, which contains a receiving tank and a discharging tool 2.

The disadvantages of this device are low operational reliability and low productivity.

The purpose of the invention is to increase the operational reliability and performance of the device.

The goal is achieved by the fact that the receiving tank is made in the form of an elliptical cone, and the unloading tool is in the form of two oppositely directed devices of continuous action, laid along the bottom of the tank, whose axes lie in a vertical plane that passes through the major axis of the ellipse.

The angle between continuous devices is equal to double the angle of repose of the bulk material.

FIG. 1 shows a device, a plan view; in fig. 2 shows section A-A in FIG. one.

The device consists of continuous unloading bodies 1 (Fig. 1 and 2) installed inside the receiving tank 2 (Fig. 1), made in the form of an elliptical cone.

15 The principle of operation of the device is as follows.

The non-averaged material is fed by the conveyor 3 (Fig. 2) into an elliptical receiving tank 2 (Fig. 1) until it is filled, after which the continuous discharge organs 1 (Fig. 1 and 2) are put into operation, which intersect all layers of different-quality material and issue on the discharge conveyors 4 (Figs. 1 and 2), the averaged mineral. Further

Claims (2)

Claim 1. A device for averaging bulk materials containing a receiving tank and an unloading working body, characterized in that, in order to increase operational reliability and performance, the receiving capacity is made in the form of an elliptical cone, and the unloading working body is in the form of two 2. positively directed devices of continuous action (for example, conveyors) laid along the bottom of the tank, the axes of which lie in a vertical plane passing through the axis of the ellipse. 2. The device according to π. 1, characterized in that. that the angle between the continuous devices is equal to the double angle of repose of the bulk material.
