: The purpose of the invention is to improve the separation efficiency by optimizing the aerodynamic regime in the pneumatic separation channel.

FIG. 1 shows the device of the visible type, FIG. 2 - a turbulizer.

The pneumatic separator includes a hopper 1, a feeder 2 enclosed in a cylindrical case, connected by a window with a vertical pneumatic separator channel 3. A guide chute 4 is hinged at the upper edge of the window. The upper part of pneumatic separator channel 3 is connected to the sediment chamber 5 and the valve The torus 6, In the lower part of the pneumo-separation channel 3, a turbulator 7 is mounted, which is a circular plate 8 rigidly fixed and evenly placed on the shaft 9 at an acute angle to the axis of the pneumatic separator. about the channel.

The device works as follows.

The material S to be divided 5 is poured into the loading box 1, from where the feeder 2 is thrown through the window along the ascending trajectory provided by the presence of the guide groove 4 into the pneumatic channel 3, where the air flow is created by the fan 6. Plates 8 TurbuLA 6664

rotary shaft. The material from the hopper 1 is thrown by the feeder 2 through the window along an upward trajectory into the PSK. In the latter, air flow is created by the fan 6. The plates of the turbulizer 7, while rotating, carry out an additional inflow of air flow to the walls of the UCS 3, leveling the velocity field of the pneumatic flow. Light particles are carried away into chamber 5, full-grained seeds arrive in the lower part of PSC 3. 2 Il.

the congestion 7, having made a rotational movement, carries out an additional inflow of air flow: to the channel walls, aligning the velocity field of the pneumatic flow. Thus, the material is affected by a relatively uniform air flow, under the action of which the lungs are carried into the sediment chamber 5, and the full-grained seeds overcome the air resistance and exit from the lower part of the pneumo-balancing channel 3.

The circular execution of the plates ensures a constant gap between the plates and the walls of the channel, creates minimal resistance compared to plates of a different shape and allows achieving a uniform distribution of the velocities of the pneumatic flow. . The uniform distribution of the plates along the axis ensures that the best result is achieved evenly with the air flow and, consequently, the separation efficiency. The best results were achieved with the angle of inclination of the .plates 8 to the shaft 9 equal to 45-fa5.
