Definitions

  • Centrifugal separator comprising a rotor, which around its circumference has outletB for intermittently discharging a separated product and outlet for discharging an operating liquid
  • the present invention relates to centrifugal separators of the kind, that comprises a rotor, which around its circumference during operation has openable first outlets for intermittent discharge of a separated product and second outlets located at a distance axially from these ones for discharge of an operating liquid, which has been supplied to the rotor for operating the first outlets, the centrifugal separator also comprising a casing around the rotor and means arranged to form a first chamber around the rotor inside the casing to receive and to lead away a separated product coming out of the first outlets and a second chamber around the rotor to receive and to lead away the operating liquid coming out of the second outlets.
  • the two chambers inside the casing around the rotor are separated by an annular separating wall.
  • This separating wall is formed by the casing itself and is formed like an upwards open groove around the rotor in said first chamber for the guidance of the received product towards an outlet.
  • the second chamber has a separate outlet for the received operating liquid.
  • the two chambers communicate with each other via a gap between the rotor and the separating wall and to the surrounding of the casing via their respective outlets, the chamber for the operating liquid . also being in communication with the surroundings of the casing via a not sealed opening in the bottom of the casing, through which the driving shaft extends.
  • the air flow created in this manner by the rotation of the rotor causes that a part of the operating liquid, which continuously or intermittently leaves the rotor, is entrained via said gap into the receiving chamber for the separated product.
  • the object of the present invention is to remove the above mentioned disadvantages in previously known centrifugal separators of the kind stated in the introductory part of the specification and to provide an effective screening between the separated product and the operating liquid, in such a way that they will not be mixed up with each other.
  • this is achieved by the fact that said two chambers are separated by means of two separating walls arranged at an axial distance from each other and extending around and close to the rotor and between themselves defining an intermediate chamber, which is open towards the rotor and communicates with the atmosphere outside the casing.
  • the centrifugal separator shown in the drawing has a rotor 1, which is driven and supported by a vertical shaft 2 and is surrounded by a stationary casing 3. Around its periphery the rotor is provided with a number of first outlets 4, through which a product separated in the rotor can be discharged intermittently. At an axial distance from these the rotor 1 is provided with at least one second outlet 5 for discharging an operating liquid, which is supplied to the rotor for operating the first outlets 4.
  • the shown rotor is also provided with a central inlet 6 for a liquid mixture, which is to be centrifugally treated, and two central outlets 7 and 8 for two liquid components separated in the rotor.
  • the casing surrounding the rotor is supported by a frame 9 and is designed with two separating walls 10 and 11, which at an axial distance from each other extend around and close to the rotor.
  • the space between the rotor 1 and the casing 3 is hereby divided into three chambers around the rotor, a first chamber 12, intended to receive and to lead away separated product coming out of the outlets 4, a second chamber 13 intended to receive and to lead away operating liquid, which flows out of the second outlet 5 and an intermediate chamber 14 delimited by the two chambers 12, 13.
  • the upper separating wall 10 is formed like a groove 15 around the rotor in the chamber 12 for the guidance of received separated product towards an outlet 16. In order to guarantee the collection and conduction away of the separated product, the groove 15 is located at a lower level than the part of the separating wall 10, which is located closest to the rotor.
  • the second chamber 13 is also provided with an outlet 17, through which operating liquid is to be conducted out of this chamber.
  • the chambers 12 and 13 communicate with the atmosphere surrounding the casing via the respective outlet 16, 17.
  • the intermediate chamber 14 communicates with the atmosphere surrounding the centrifugal separator via a passage 18 in the frame 9.
  • the pressure in the above-mentioned and in the following claims mentioned atmosphere, to which the intermediate chamber 14 is connected via the passage 18, is normally atmospheric pressure, but the passage 18 can also be connected to another pressure.

Abstract

Un séparateur centrifuge comprend un rotor (1) ayant à sa circonférence, pendant son fonctionnement, des premiers orifices ouvrables (4) de décharge intermittente d'un produit séparé et des deuxièmes orifices axialement écartés des premiers (4) pour décharger un liquide de travail fourni au rotor pour faire fonctionner les premiers orifices (4). Le séparateur centrifuge comprend également un logement (3) qui entoure le rotor (1), un dispositif qui forme une première chambre (12) autour du rotor, à l'intérieur du logement, pour recevoir et éloigner un produit séparé sortant par les premiers orifices (4) et une deuxième chambre (13) agencée autour du rotor pour recevoir et éloigner un liquide de travail qui sort par les deuxièmes orifices (5). Pour éliminer les risques de mélange du produit séparé et du liquide de travail provoqués par des courants d'air d'entraînement se formant entre les deux chambres (12 et 13), celles-ci sont séparées l'une de l'autre par deux cloisons (10 et 11) axialement écartées l'une de l'autre et s'étendant autour et près du rotor (1). Ces cloisons délimitent entre elles une chambre intermédiaire (14) ouverte vers le rotor (1) et en communication avec l'atmosphère à l'extérieur du logement (3).
