The invention relates to devices for transporting powdered materials and can be used in the microbiological, medical, chemical and other sectors of the industry.

The purpose of the invention is to increase the reliability of transportation and reduce energy intensity.

The drawing shows the apparatus, the abundant material, and the resulting aerated mixture rushes into the transport conduit. The regulator 9 of the flow rate of the injected air allows changing the degree of aeration of the material without additional energy costs. Since the discharge pipe 4 of the outlet of aerated material is located along the axis of chamber 1, this prevents material from entering the toroidal chamber 1, its sticking to the walls

The Usta-15 of the overall dimensions of the chamber, which is new on the wall of the chamber 1, the hopper 5 with the feed neck 6 and the unloading 3 nozzle, forms an annular nozzle 7 for air leaks. For dosing the powder and controlling the consumable characteristics of the device, there is provided a gate 8 and a regulator 9. At the same time

Claims (2)

1. A device for pneumatic conveying of a powdered material, comprising a loading nozzle, a toroidal mixing chamber coaxially mounted under it with a tangential air supply nozzle and a discharge nozzle attached to the toroidal mixing chamber, 1-de ("is the diameter of the charging 3 nozzle; 25 characterized in that, in order to increase reliability of transportation and reduction of energy intensity, the discharge pipe is placed coaxially with the loading pipe installed to form an annular nozzle relative to the horizontal mixture — it enters the toroidal chamber 1, the perfect chamber for air leaks, swirls and leaves the loading, unloading and tangent „0, б4, "G d - the diameter of the discharge pipe 4; d-i - the diameter of the tangential nozzle 2 air supply. The device works as follows. Air through tangential nozzle 2 unloading 4 pipe. In the axial zone of chamber 1, a vacuum zone is created, the size of which is related by the formula , 6 35 social nozzles are made with diameters related to the formula ,, d where do is the diameter of the inlet; At the outlet of the discharge pipe 3, the air flow injected through the annular nozzle 7 draws air from the hopper 5. The vortex air stream flowing from the toroidal chamber 1 ensures uniform mixing of the powdered material and the resulting aerated mixture rushes into the transport pipeline. The regulator 9 of the flow rate of the injected air allows changing the degree of aeration of the material without additional energy costs. Since the discharge pipe 4 of the outlet of aerated material is located along the axis of chamber 1, this prevents material from entering the toroidal chamber 1, its sticking to the walls and seal the size of the camera, Invention Formula reliability of transportation and reduction of energy consumption, the discharge pipe is placed coaxially with the loading pipe, installed to form an annular nozzle relative to the horizontal mixing chamber for air leaks, while loading, unloading and tangent 5 d social nozzles are made with diameters related to the formula ,, d where do is the diameter of the inlet; d is the diameter of the discharge pipe;  - diameter of the tangential nozzle. 2. A device according to claim 1, characterized in that the annular nozzle is adjustable.
