Description

VIBRATION BATCHER OF BULK MATERIALS

one

The invention relates to a vibration technique.

Known vibrating dispenser bulk materials, comprising a housing, vibrators, hopper with a tapered output and a ball gate.

However, in the course of operation of a known dispenser, material sticks to the metering elements, which reduces the metering accuracy.

In addition, in the known device it is difficult to control the flow of material when its physical properties change.

In order to increase the accuracy and broaden the range of dosing in the proposed dispenser, the conical output of the hopper installed between the vibrators is a double funnel, the inner wall of which has cuts along the generatrix, and the ball shutter is equipped with a multi-petal basket covering it and a replaceable weight.

The drawing shows the described dispenser.

Vibrators 2 and a hopper 3 with a conical outlet are installed in the housing / double funnel 4, the inner wall of which has cuts 5 along the generatrix. The ball valve 6 is installed inside the funnel, covered by the cleaner, made in the form of a multilobe basket 7, and equipped with a removable load 8.

The material to be dosed is poured into the hopper 3, which is vibrated by the vibrators 2. When the hopper oscillates, the ball gate 6 periodically rises upwards, and a gap is created between the gate and the inner wall of the funnel 4 to allow the material to flow out. The multi-leaf basket 7 performs a chaotic rotational motion, clearing the shutter from the material adhering to it. During vibration, elastic flexural vibrations also occur in the petals of the inner funnel formed by the cuts 5, which prevent the material from sticking to the funnel walls.

By changing the value of the load S, the consumption of the material is controlled by changing its particle size distribution and the bulk weight.

Subject invention

A vibrating bulk materials dispenser comprising a housing, vibrators, a hopper with a cone outlet and a ball gate, characterized in that, in order to increase the accuracy and broaden the metering range, the bevel output of the hopper installed between the vibrators is a double funnel, the inner wall of which has cuts generator, and the ball valve is covered by a cleaner, made in the form of a multilobe basket, and a replaceable load.
