Regarding separation, this centrifuge also has a casing around the rotor and a first A rotor inside the casing that receives and transports the separated product coming out of the outlet. a first chamber around the periphery of the chamber and a rotor for receiving and conveying the working fluid coming out of the second discharge port; and means arranged to form a second chamber around the heater. In known centrifuges of this kind with a rotor supported on a vertical axis, the case These two chambers around the rotor inside the singe are separated by an annular separating wall. This separation wall is formed by the casing itself, and the receiver is A groove with an open top is provided around the rotor in the 111 chamber to guide the flow to the discharge port. These two chambers are formed through the gap between the rotor and the separating wall. communicate with each other and around the casing through their respective outlets, and The chamber for the dynamic fluid is an unsealed opening in the bottom of the casing through which the drive shaft passes. It communicates with the periphery of the casing through the section. During operation of the above-mentioned known centrifuge, the air around the centrifuge rotor 9 flows through the rotor. Being drawn into the external friction of snoring. This has two effects like a pump. It occurs in the chamber of The designs of these centrifuge chambers and the outlets that communicate with them are different. As a result, a portion of the empty package flows through the working liquid outlet into the second chamber and from there Furthermore, it flows into the first chamber through the gap between the rotor and the separation wall, and the discharge port for the separated products. Empty cartridges also have the phenomenon of flowing out. The aforementioned opening in the bottom of the casing There is a possibility that the oil from the bearing located at the bottom is emptied into the second chamber through There is a risk of being entrained into the two chambers by the flow of air. The side flow generated in this way by the rotation of the rotor can be continuous or intermittent.

It may cause you to be accompanied When the outlet of the rotor for the separated products is opened, the air stream flows out of the rotor. affected by the output product flow. The pressure in the first chamber is the sorotar and casing. air flow in the opposite direction through the gap between the two. This kind of anti- The counter-directional airflow entrains a portion of the ejected separation product into the chamber that receives the working liquid. Ru. How many airflows and associated movements of working liquid and separation products are each described above? Therefore, the working liquid gets into the separation product and/or or if there are other reasons why a reduction in the concentration of the separated product is usually undesirable. Even when the separation product mixes with the working fluid, it is often unacceptable; , on the one hand, the separated products contaminate the working fluid, and on the other hand, the separated products contaminate the rotor. Separation products may enter the working fluid and pose a risk of shutting it down. It is undesirable for it to flow into the receiving chamber. The purpose of the invention is to: 1. The purpose of the invention is to use known centrifugal separators of the type mentioned in the introduction to the detailed description This eliminates the above-mentioned problems in The goal is to effectively partition the gap between them. According to the invention, this is done separately from each other. arranged around and close to the rotor, forming an intermediate chamber between them. This is done by separating the two chambers by two separating walls. And in this The interchamber is open in the direction of the rotor and communicates with the atmosphere outside the casing. Next, the present invention will be described in more detail with reference to the accompanying drawings. This figure shows the present invention. Showing part of a centrifuge. Some show side views, some show cross sections, The centrifugal separator shown in the drawing is driven and supported by a vertical shaft 2 and has a stationary casing 3. It has a rotor 1 which is surrounded by a rotor. There are some on the outer surface of the rotor l. There is a first discharge port 4 from which the product separated by the rotor 1 is intermittently discharged. be done. At a distance from these in the axial direction, a roller is placed in order to operate the first discharge port 4. The rotor has at least one second outlet 5 for discharging the working fluid supplied to the rotor. 1 has. The rotor in the figure is also. Central injection of liquid mixtures processed by centrifugation port 6, and two central discharge lowers for the two liquid components separated by a rotor and 8. The casing surrounding the rotor is supported by a frame 9 and is axially two separating walls 1o extending around and near the rotor at a distance of 】l, the space between the rotor 1 and the casing 3 is thus It is divided into three halls around the heater, of which the -chamber 12 is connected from the first outlet 4. The second chamber 13 receives and carries out the effluent separated product, and the second chamber 13 receives the outflowing separation product from the second outlet 5. The intermediate chamber 14 is divided into two chambers 12. The upper separation wall 10, which is delimited by the Separation formation formed around the rotor in the chamber 12 as a groove 15 leading to the To ensure collection and guidance of objects, the groove 15 is located in the separation zone closest to the rotor. It is placed at a lower position than the wall 1o. The second separation chamber 13 likewise has an outlet 17, by means of which the working liquid is directed out of this chamber. The chambers 12 and 13 are guided through the casing through respective outlets 16.17. Connecting with the winding atmosphere, In the embodiment shown, the intermediate chamber 14 is centrifuged by the passage 18 in claim 9. It communicates with the atmosphere surrounding the machine. By designing the centrifuge in the manner described above, a chamber 12 for receiving the separated products; Flow to and from the chamber 13 receiving the working liquid is prevented. Instead, these two The unavoidable airflow from the direction of the chamber is such that each path of the airflow has the lowest airflow resistance. therefore, it flows out of the passage 18 via the intermediate chamber 14 and is therefore entrained by the air flow. The product and the working liquid flowing out each exit via a passage 18, thus two The spaces 12 and 13 are effectively partitioned so that the separation product and the working liquid do not mix and become contaminated. There is no danger of matching. In addition, in the foregoing and following claims. The pressure of the air connected via the intermediate chamber 14 is normally atmospheric pressure, but ] 8 can also be connected to another pressure. international search report
