This invention relates to pneumatic conveying and can be used to evenly supply bulk materials.

The purpose of the invention is to simplify the design.

The drawing shows the proposed device, the cut.

The device consists of a vertically installed hermetic container 1 with a conical bottom 2, in the center of which a discharge opening 3 is made, equipped with a feed gas supply nozzle k and a cone 5 in the form of a cone placed on the surface of the material with a gap relative to the vessel walls.

The device works as follows.

Before work, remove the lid from the container 1, remove the svardopusher 5 and pour the material into the container. Then, the binder 5 is lowered onto the surface of the material and a cover is placed on the container 1. L. more gas in the tank 1 through the pipe. The gas, the passage through the gap between the rotator 5 and the walls of the tank 1, pseudo-liquefies the material in the gap, fills the space between the solid particles in the tank 1 and, approaching the aperture 3, carries the material with it. At the same time, the skimmer 5 is evenly lowered, due to its mass, excluding the hang of the material. In addition, during the outflow of material from the tank, the baler prevents the formation of a funnel on the surface

the rial, in the center of which, when the container is not yet completely empty, a gas can break through into the hole.

The maximum size of the area of the annular gap is chosen not greater than the area of the discharge opening to ensure fluidization of the material in the gap and, thereby, prevented it from sticking to the vessel walls. In order to limit the pressure loss in the gap, its area is chosen to be not less than the cross-sectional area of the gas supply nozzle. Performing a cone with an opening angle equal to the opening angle of the conical bottom, facilitating the most complete discharge, ensures simplicity of design,
