A centrifuge including a rotor having a second outlet for discharging a working liquid supplied to the rotor for operating an outlet, the centrifuge comprising a casing around the rotor and a first outlet. Arranged to form a first chamber around the rotor inside the casing for receiving and carrying out the emerging separation products and a second chamber around the rotor for receiving and carrying out the working liquid emerging from the second outlet.

口部を通じてケーシングの周囲と連通する。In a known centrifuge of this kind with a rotor supported on a vertical axis, these two chambers around the rotor inside the casing are separated by an annular separating wall. This separating wall is formed by the casing itself and is formed like an open-ended groove around the rotor in the first chamber for guiding the received product to the outlet. These two chambers communicate with each other through the gap between the rotor and the separating wall and through the respective outlets around the casing, and the chamber for the working liquid is sealed at the bottom of the casing through which the drive shaft passes. It communicates with the perimeter of the casing through an opening that is not open.

る。During operation of the known centrifuge described above, the air around the centrifuge rotor is drawn into rotation by friction on the outside of the rotor. This produces a pump-like effect in the two chambers. As a result of the different designs of the chambers of these centrifuges and the outlets communicating with them, some of the air flows into the second chamber through the outlet of the working liquid and from there between the rotor and the separating wall. Phenomenon occurs in which the separated product flows into the first chamber and flows out from the separated product discharge port. Air can also flow into the second chamber through the aforementioned openings in the bottom of the casing and there is a risk that oil from the underlying bearing will be entrained in the two chambers by the air flow.

れる原因となる。The airflow thus generated by the rotation of the rotor is
A portion of the working liquid, which continuously or intermittently leaves the rotor, causes it to be entrained in the chamber for receiving the separated product through the gap.

る。このような反対方向の気流は、排出された分離生成
物の一部を作動液体を受け取る室に同伴する。When the outlet of the rotor for the separated products is opened, the air stream is influenced by the product flow leaving the rotor. The pressure in the first chamber increases to the extent that an air flow in the opposite direction is generated through the gap between the rotor and the casing. Such an opposite flow of air entrains some of the discharged separation products in the chamber receiving the working liquid.

入することは望ましくない。The aforementioned air flow, and the associated movement of the working liquid and the separated products, each cause several problems. Therefore, it is usually undesirable for the working liquid to enter the separation product and / or to reduce the concentration of the separation product. For other reasons, it is often unacceptable for the separation products to mix with the working liquid. Furthermore, on the one hand there is a risk that the separation products will contaminate the working liquid and on the other hand there is a risk that the separation products will enter and stop the working system of the rotor, so that the separation products flow into the chamber receiving the working liquid. Is not desirable.

ーシングの外側の大気と連通する。The object of the present invention is to eliminate the above-mentioned problems in known centrifuges of the type mentioned in the introductory part of the detailed description of the invention, and to work between the separation products and the working liquid so that they do not mix. It is to partition it. According to the invention, this is done by separating the two chambers by two separating walls which are spaced apart from each other and which extend around and near the rotor, forming an intermediate chamber between them. The intermediate chamber is opened toward the rotor and communicates with the atmosphere outside the casing.

７および８を有する。The centrifuge shown in the drawing comprises a rotor 1 driven and supported by a vertical shaft 2 and surrounded by a stationary casing 3. There are several first outlets 4 on the outer surface of the rotor 1, from which the products separated by the rotor 1 are intermittently discharged. The rotor 1 has at least one second outlet 5 which is axially spaced from them and which discharges the working liquid supplied to the rotor for actuating the first outlet 4. The rotor in the figure also has a central inlet 6 for the liquid mixture to be processed by centrifugation and two central outlets 7 and 8 for the two liquid components separated by the rotor.

１０の部分より低い位置に置かれる。The casing surrounding the rotor is supported by a frame 9 and is of a design with two separating walls 10 and 11 extending around and near the rotor axially spaced from each other. The space between the rotor 1 and the casing 3 is consequently divided into three chambers around the rotor,
The first chamber 12 receives and carries out the separated product flowing out from the first outlet 4, the second chamber 13 receives and carries out the working liquid flowing out from the second outlet 5, and the intermediate chamber 14 has two chambers. The boundary is defined by 12 and 13. The upper separation wall 10 is formed around the rotor in the chamber 12 like a groove 15 which guides the received separation products to the outlet 16. In order to ensure the collection and guidance of the separated products, the groove 15 is located lower than the part of the separating wall 10 located closest to the rotor.

通路１８により遠心分離機を取り巻く大気と連通する。In the illustrated embodiment, the intermediate chamber 14 is in communication with the atmosphere surrounding the centrifuge by means of a passage 18 in the frame 9.

なる。By designing the centrifuge in the manner described above, flow is prevented between the chamber 12 that receives the separation product and the chamber 13 that receives the working liquid. Instead, the unavoidable airflow from these two chambers flows out of the passage 18 via the intermediate chamber 14 because the respective paths of the airflow have the lowest airflow resistance. Therefore, the product and the working liquid entrained by the air flow respectively flow out through the passage 18. In this way, the two spaces 12 and 13 are effectively partitioned so that there is no risk of mixing and contaminating the separation products and the working liquid.
