Description

The invention relates to the storage of bulk materials, and in particular to devices for preventing the formation of arches during unloading of material from silos of stationary and mobile means.

The purpose of the invention is to increase the reliability of the device in operation.

In FIG. 1 shows the proposed device; in FIG. 2 is a section AA in FIG. 1.

A device for destroying arches of bulk material in a hopper comprises a horizontal spider 3 suspended in a hopper 1 on elastic elements, for example, springs 2. Blades 4 are rigidly fixed to the crosspiece 3, which are metal sheets. In each blade 4, vertical slots are made, and the length of the slots is shorter than the length of the sheets at the site of the cut. The number and width of strips and slots are governed by the physicomechanical properties of the bulk material.

The device operates as follows.

When loading the hopper 1, the device for breaking the arches occupies the average possible position in the hopper 1. When the discharge window is opened (not shown in the drawing), bulk material from the lower part of the hopper 1 is pulled out, and the amount of bulk material from each part of the cut flow will be uneven . The pressure of bulk material on each side of the blades 4 is different,

therefore, the strips of which the blades 4 are composed are folded in the direction from which more material was poured out and the pressure, accordingly, became less. As a result, the volume of those parts of the stream where the bulk material is in greater quantity increases, the adhesion between the particles of material there decreases and a portion of the material is released under the action of gravity from these parts of the hopper 1. Further, the strip of blades 4 bend in the opposite direction, and the process is repeated . The deflection of the blades 4 in one direction or the other creates an oscillation of the entire system, and the suspension of the blades 4 on the elastic elements 2 reinforces these oscillations. The separation of the blades 4 by cuts into separate strips allows the device to respond to any pressure changes in different parts of the flow of bulk material and thereby increase the vibrations of the blades 4, which increases the outflow of bulk material from the hopper.

SUMMARY OF THE INVENTION A device for breaking arches of bulk material in a hopper, comprising a cross located in the hopper, the blades of which are metal sheets, characterized in that, in order to increase operational reliability, the cross is spring-loaded in the upper part relative to the hopper body, and in each blade has vertical slots.
