Description

In the proposed air separator, in order to increase the rotational movement of the air jet after it passes through windows provided with tangentially mounted flaps and adjustable by an annular shield, the blades rotating on the vertical axis are located in the jet path into the exhaust pipe.

In separate forms of the separator, the blades can also be placed inside a pipe constituting a part of the exhaust pipe inside the separator, or a guide disk can be placed on the side of the exhaust pipe between the vanes to the side of the exhaust pipe.

In the schematic drawing of FIG. 1 shows a vertical section of an air separator; FIG. 2 - horizontal section of the separator; FIG. 3 - view of the blades with a guide disk; FIG. 4 - view of the blades inside the pipe.

The separator consists of two funnels. The internal funnel is a cone ending at the top with a solid cylindrical part 10, which acts as a separation chamber, where it is possible

free development of centrifugal rotational flow, whereby large particles belong to the cylindrical wall of the inner funnel. The windows for the passage of the mixture from the annular space 9 into the internal funnel are provided with vortex tangentially mounted flaps 7 and annular shield 5 (Fig. 2) that regulate the separation process.

The slider // vortex flaps 7 can be placed at any angle to the radius passing through the center of the cylindrical separation chamber and through the axis of rotation of the flaps.

Ring shield 5 using the rod 6 can be raised or lowered by adjusting the size of the windows. The blades 2 rotating on the vertical axis are located along the path of the jets at the exit of the apparatus, which accelerates the rotational movement of air masses that already received a centrifugal rotational movement during the passage between the tangentially set flaps.

In another form of the separator (Fig. 3) for directing air jets into the exhaust pipe laterally between the blades 2, a guide disk 3 is placed under the latter. Suction of thin material can be performed through the end of the nozzle 8 (Fig. 4), a part of the exhaust pipe inside the separator, with blades 12 placed inside the nozzle.

For the case when the separator feeds through the screw feeder / enters the material with the presence of large grains that are picked up by the air flow, a device is provided in the discharge nozzle of the conical insert 4. As the device is under vacuum, then along the adjustable annular gap between the conical insert 4 and the lower edge the nozzle will flow into the separator an upward, weak air flow, sufficient only to clean the fine particles out of the coarse material coming out of the nozzle.

In the embodiment of FIG. 4 —the blades 12 are located inside the nozzle, but without a guide disc under the nozzle.

The subject matter of the invention.
