BULK MATERIAL PNEUMATIC SEPARATOR Russian patent published in 2023 - IPC B07B4/02 

FIELD: separation equipment.

SUBSTANCE: device for the separation of bulk materials; it can be used for separation of bulk materials in many sectors of the national economy, as well as in agriculture and the flour-milling and elevator industry for grain separation. A pneumatic separator for bulk materials includes a fan with an outlet pipe, a separation channel, a loading device located above the channel, and receivers for separation products in the lower part of the channel. The separation channel is made of two parts connected to each other telescopically. The loading device is installed above the first telescopic part of the channel connected to the fan outlet. Receivers of separation products are located under the second telescopic part of the channel. At the bottom, in the second telescopic part of the channel, there is a discharge window for exit of the heavy component. A light component receptacle is installed at the open end of the second part. The length of the first part of the channel is greater than the length of the second part of the channel l₁>l₂. The loading pipe is equipped with a cone-shaped insert, under which there are two adjustable flaps. The unloading window of the heavy component is made of a rectangular shape with a long side along the generatrix of the second telescopic part of the channel. A control valve is located under the discharge window on the free end side.

EFFECT: improved quality and efficiency of separation of bulk material during its transportation in pipelines under the influence of gravitational forces.
