Description

The invention relates to apparatus for separating heterogeneous liquid mixtures in the field of centrifugal forces.

The purpose of the invention is the ability to maintain a stable temperature during centrifugation.

In FIG. 1 schematically shows a centrifuge, a longitudinal section; in FIG. 2 — section A — A in FIG. 1; in FIG. 3 --- section B — B in FIG. 1; in FIG. 4 - section B - B in FIG. 1 (paddle wheel).

The centrifuge contains a housing 1 with a chamber 2, a housing cover 3 with ducts 4 mounted on the inner surface of the rotor 6, mounted in the chamber 2 on the hollow shaft 5, provided with a fairing 7 for air, glasses 9 pivotally mounted on the trunnions 8 and drive 10. On the hollow shaft 5, a blade wheel 11 is installed outside the chamber 2. The hollow shaft 5 between the blades 12 of the wheel 11 has channels 13 for venting air ²⁰ from the chamber 2.

The centrifuge operates as follows.

With the cover open 3, the centrifuged heterogeneous liquid is poured into ₂ s glasses 9. The drive K) is turned on, transmitting rotational movement to the rotor 6 through the hollow shaft 5. When the rotor 6 rotates together with the cowling 7, which serves to reduce the friction of the rotor, the glasses 9 rotate on the pins 8 to horizontal position. The process of separation of the liquid ₅ under the action of the centrifugal forces of the rotor.

During the rotation of the rotor, air is thrown off by the walls of the fairing 7 from the center to the walls of the chamber 2, i.e. The cowl rotor functions as a centrifugal fan. A low-pressure zone of ¹⁰ pressure is created in the center of chamber 2 and a high-pressure zone at the periphery of the chamber. As a result, air under pressure enters the air ducts 4 and then to the central outlet 14 (in Fig. 1, the air path is shown by arrows ₁₅ ). Since the outlet 14 is located above the cavity of the shaft 5, air under pressure passes into this cavity and passes through the channels 13 to the blades 12 of the wheel 11. When the wheel rotates, the blades discard the air entering through the hollow shaft. Thus, air is removed from the chamber simultaneously by two devices - a rotor 6 with a fairing 7 and a blade wheel 11 ·. This achieves a high degree of pumping air from the chamber 2, which significantly reduces the friction of the rotor against the air. Conditions are created to maintain a stable temperature during centrifugation.
