SU115087A1 - Continuous Centrifuge - Google Patents

Description

Continuous centrifuges are known, including two cylindrical drums concentrically mounted on a common shaft inside stationary corius and rotating at different speeds. The outer drum has perforated walls, and the inner drum is provided with a screw on the outer surface. Such centrifuges cannot be effectively used to centrifuge the fibrous material due to its specific characteristics.

A centrifuge according to the invention allows centrifuging of a fibrous material, such as wool, for which it is provided with a fixed casing mounted in the inner drum to direct the material to the walls of the outer drum, and the gap between the outer drum and the cylindrical surface formed by the inner drum cheek increases from bottom to top. : the walls of the inner drum have windows at the bottom for the material to reach the walls of the outer drum.

The fixed casing for guiding the material is made in the form of a cylindrical shell, equipped at the bottom with jacking blades for moving the material to the inner drum windows, and at the top - with a feed funnel and a cylindrical box with an opening, to which the tangential nozzle for ejection of the pressed material adjoins.

FIG. 1 shows a continuous centrifuge; in fig. 2 shows sections according to AA and BB in FIG. one.

All centrifuge units are enclosed in a fixed casing assembled from three parts: lower, middle 2, and upper 5. Two cylindrical drums rotating in one direction with different speeds are mounted on a common shaft 4. Outdoor ba№115087-2 -

The raban 5 has perforated walls, and the inner drum 6 is provided on the outer surface with a screw 7.

In the inner drum 6 is mounted a stationary casing 8, made in the form of a cylindrical shell, equipped with bottom jacks 9, and at the top - a feed funnel 10 and a cylindrical box 11 with a hole, which adjoins the tangential nozzle 12.

The inner drum 6 has at the bottom three windows 13 for the passage of fibrous material from the casing 8 to the perforated walls of the outer drum 5.

The drums 5 and b are driven into rotation by an electric motor (not shown) through a gearbox 14, which is designed so that the outer drum 5 and the inner drum 6 with the auger rotate in the same direction, and the number of revolutions of the drum 6 slightly exceeds the number of revolutions of the drum 5 .

The drums 5 and 6 are made and assembled in such a way that the gap between the inner surface of the drum 5 and the cylindrical surface formed by the screw 7 of the inner drum 6 increases from bottom to top.

The operation of the continuous centrifuge is as follows.

Fibrous material, such as wool, is loaded with water through a funnel 10 into the interior of kozhzha 8. Under the action of jacking blades 9, the fibrous material moves through the openings 13 of the inner drum 6 between the turns of the screw 7, presses against the inner perforated wall of the drum 5 and gradually rises with the rotating screw 7 between the drums 5 and 5 up.

Due to the fact that the gap between the outer drum 5 and the cylindrical surface formed by the screw 7 increases from bottom to top, no wedging of fibrous material between the screw and the perforated wall of the outer drum 5 does not occur.

Under the action of centrifugal force, the fibrous material is pressed against the perforated wall of the drum 5 and pressed.

The pressed fibrous material, coming up to the top of the drum 6, is directed into a cylindrical box 11 with a hole and through the adjacent nozzle 12 is thrown out of the centrifuge, and the water goes through the tray (not shown), which is in the housing, into the sewer.

The centrifuge is continuous.
