Definitions

  • the invention relates to a ventilation device for a crankcase of an internal combustion engine with the features of the preamble of claim 1.
  • the invention also relates to a method according to claim 15 and a use according to claim 17.
  • Such a ventilation device is known for example from DE 198 03 872 AI and has a centrifugal oil separator which has a mixture inlet for an oil-air mixture and an air outlet for clean air and an oil outlet for oil.
  • the centrifugal oil separator used in the known ventilation device has a rotatingly driven housing which has an outflow funnel which is oriented coaxially with the axis of rotation of the housing and which forms the air outlet coaxially with the axis of rotation. Radially between this outflow funnel and an outer housing wall, the mixture inlet is essentially annular. Baffles protrude into this mixture inlet and thereby force a multiple deflection of the flow of the Oil-air mixture. This deflection allows the oil to separate from the chicanes. The oil is transported to the outer walls of the rotating housing by the centrifugal forces. In these outer walls, several oil outlet holes are provided at suitable points through which the separated oil can escape from the housing. The clean air, cleaned of oil, exits the interior of the housing through the air outlet.
  • the clean air emerging from the centrifugal oil separator is usually fed to the intake tract of an internal combustion engine.
  • the clean air contain as little oil residue as possible.
  • the oil consumption of the internal combustion engine can be reduced, on the other hand, the emission behavior of the internal combustion engine can be improved.
  • a particularly high degree of purity for the clean air is desirable in order to avoid damage to the sensitive components and influence on the measured values.
  • the present invention deals with the problem of specifying an embodiment for a ventilation device of the type mentioned at the outset which enables particularly high-quality oil separation.
  • the invention is based on the general idea of designing the centrifugal oil separator as a plate separator. It has been shown that a particularly high-quality oil separation can be achieved with the aid of a plate separator, so that the clean air emerging from the plate separator contains no or only very small amounts of oil or oil mist.
  • the plate separator can preferably have a stator designed as a housing, in which a rotor is accommodated, which has a plurality of plates, which are arranged parallel to one another along the rotor axis and coaxial to the rotor axis. A gap is then formed in each case between two adjacent plates, which connects an annular space formed in the interior of the rotor with a space which surrounds the rotor in the interior of the housing.
  • the desired cleaning effect can be achieved for a given volume flow and a given pressure drop. It is clear that the cleaning effect also depends on the speed of the rotor.
  • the plates can form a plate block in which adjacent plates are fastened to one another, this plate block being connected in a rotationally fixed manner via its axial ends to a central rotor shaft of the rotor.
  • the plate block forms a one-piece assembly, which is attached to the rotor shaft as such. Accordingly, at least the plates which are arranged between the axially outer plates are not directly connected to the rotor shaft. The plate block is then connected to the rotor shaft via the two plates located axially on the outside. This design simplifies the manufacture of the plate separator, since all the plates are fixed to the rotor by fastening the plate block to the rotor shaft.
  • At least two adjacent plates can form a stack of plates which is made in one piece.
  • a stack of plates can be produced, for example, by an injection molding process.
  • the one-piece production of this stack of plates means that the associated plates are already firmly connected to one another, which means that additional fastening steps can be omitted.
  • a plate block can be formed by at least one stack of plates. Since the plates do not have to be attached to one another in a stack of plates, the production of the plate block is simplified. Another important advantage of this embodiment results when a plurality of stacks of plates form the respective plate block, since the number of plates in the plate block can then be varied particularly easily. For example, a stack of plates always includes five plates.
  • a plate block should have 15 plates in a first variant and 20 plates in a second variant. The number of plates depends, for example, on the volume flow to be cleaned. To produce the first variant, three stacks of plates are thus connected to one another. To form the second variant Accordingly, four stacks of plates are connected to each other. The additional effort for the formation of two different variants is minimal.
  • spacing elements in the direction of the rotor axis between adjacent plates, which produce the respective gap.
  • plates and spacer elements can thus be stacked on top of one another and connected to one another in one operation, for example by a welding process.
  • FIG. 1 shows a longitudinal section through a plate separator of a ventilation device according to the invention.
  • a ventilation device (not shown) has a plate separator 1, which has a stator 2 and a rotor 3.
  • the stator 2 can for example be attached to a crankcase of an internal combustion engine.
  • the rotor 3 is rotatably arranged in the stator 2, the stator 2 in the special embodiment shown here having corresponding radial bearings 4 and 5 with which a rotor shaft 6 of the rotor 3 is rotatably mounted on the stator 2.
  • the stator 2 forms a housing 7 in which the rotor 3 is arranged. In the interior of the housing 7, a space 8 is also formed, which surrounds the rotor 3.
  • the rotor 3 has a plurality of disks 9 which are arranged parallel to one another and coaxially to the rotor axis 19 along a rotor axis 19.
  • a gap 10 is formed between two adjacent plates 9. Each of these gaps 10 connects the space 8 lying radially outside with respect to the plates 9 with an annular space 11 lying radially inside with respect to the plates 9, which is formed inside the rotor 3 and extends coaxially to the rotor shaft 6.
  • This annular space 11 is connected to a first connection 12, while the space 8 is connected to a second connection 13 and to a third connection 14.
  • the annular space 11 opens directly on the low-pressure side of a compressor 15, which is designed here as a radial compressor.
  • a compressor wheel 16 of the compressor 15 is fixed in a rotationally fixed manner directly on the rotor shaft 6 of the plate separator 1. From the radially inner low-pressure side of the compressor wheel 16, the air provided there by the annular space 11 is conveyed radially outward within the compressor wheel 16, where it reaches a pressure chamber 17 of the compressor 15. This pressure chamber 17 is now connected to the first connection 12.
  • the compressor 15 serves on the one hand to substantially compensate for the pressure loss which inevitably occurs when the plate separator 1 flows through.
  • the compressor 15 can also be dimensioned such that it generates a pressure increase between the second connection 13 and the first connection 12, that is to say above the separator-compressor unit.
  • the first connection 12 serves as an air outlet for the clean air cleaned from the oil
  • the second connection 13 serves as a mixture inlet for the unpurified oil-air mixture.
  • the third connection 14 forms an oil outlet through which the separated or separated oil can be removed from the space 8. It is clear that in another embodiment, which is not equipped with the compressor 15, for example, the direction of flow of the plate separator 1 can also be reversed, so that the first connection 12 serves as a mixture inlet and the second connection 13 serves as an air outlet.
  • this second connection 13 is aligned axially parallel to the rotor axis 19, in another embodiment this second connection 13 can also be arranged inclined or transverse to the rotor axis 19, in particular radially to the rotor axis 19 or tangential to the housing 7.
  • Spacer elements 18 are arranged between adjacent plates 9, only a few of which are shown symbolically for the sake of clarity in FIG. 1. These spacer elements 18 are, for example, punctiform or spherical or in the form of webs. The spacer elements 18 keep the adjacent plates 9 at a distance in the direction of the rotor axis 19, as a result of which the gaps 10 can be defined. In a preferred embodiment, these spacer elements 18 are made in one piece with the plates 9. For example, each plate shows 9 on a top of the space 8 facing a plurality of such spacer elements 18, which are supported in the assembled state on the underside of the adjacent plate 9 facing the annular space 11.
  • the plates 9 are designed with the shape of a truncated cone-shaped sleeve, so that the surface line of the plates 9 runs inclined with respect to the rotor axis 19.
  • the surface lines of the plates 9 form an angle of approximately 45 ° with the rotor axis 19. It is clear that other angles up to 90 ° are also possible.
  • the horizontal lines shown in the annular space 11 show the radially inner inner edges of the plates 9 and the radially inner mouths of the gaps 10.
  • the stacked plates 9 are axially fixed between two holding elements 21 and 22, the contour of which cooperates with the plates 9 are shaped to be complementary to the respective axially outer plates 9. In this way, a gap 10 is also formed between the holding elements 21, 22 and the plate 9 supported therein. Correspondingly, 10 spacer elements 18 can also be arranged in these axially outer columns.
  • the holding elements 21 and 22 are fixed in a rotationally fixed manner on the rotor shaft 6.
  • the adjacent plates 9 are each fastened to one another, as a result of which all plates 9 are combined to form a uniform plate block 20.
  • the connection between the plates 9 can for example be made via the spacer elements 18 which, for. B. are welded to the adjacent plate 9. It is also possible for the plates 9 to be fastened to one another by means of special connecting webs or other connecting elements, but these are not shown here.
  • the unitary plate block 20 formed in this way can then be mounted on the rotor shaft 6 in a particularly simple manner, the plate block 20 also being fixed via the holding elements 21, 22.
  • each plate 9 is separately loaded on the rotor shaft 6. is fixed, for example, each plate 9 is positively attached to the rotor shaft 6.
  • a preferred embodiment 9 may be produced in one piece or integral multiple plates, which can be realized in particular by means of a plastic injection molding process'.
  • the plates 9 which are jointly produced in one body are referred to below as "stack of plates".
  • stamp of plates it is possible to produce all the plates 9 by means of an integral injection-molded part, so that the plate block 20 forms an integral stack of plates.
  • the Plate block 20 is constructed from a plurality of plate stacks, such a plate stack is identified by a curly bracket and designated by 23.
  • This plate stack 23 comprises, for example, three plates 9 which are integrally formed in one piece.
  • the manufacture of the plate separator 1 is simplified if different variants are to be made available for the plate separator 1.
  • the procedure for producing such a plate separator 1 is preferably as follows:
  • the particular application of the plate separator 1 or the venting device equipped with it specifies a volume flow which is to be cleaned of oil. Depending on this volume flow, the number of plates 9 with which the plate separator 1 must be equipped is determined in order to to be able to achieve the desired degree of purity.
  • the plate block 20 can then be assembled or assembled.
  • the plate stacks 23 are prefabricated, of which, for example, variants with a different number of plates can also be present.
  • the individual plate '9 or the individual stack of plates 23 are then connected to each other depending on the embodiment to be an easy manipulable unit, namely the block of plates 20, form.
  • the plates 9 or the plate block 20 are fixed between the holding elements 21 and 22 on the rotor shaft 6, additional fastening measures for connecting the plate block 20 to the holding elements 21, 22 being able to be provided.
  • the plate separator 1 is driven via its rotor shaft 6, it being possible in principle for any drive for the rotor shaft 6 to be suitable.
  • the rotor shaft 6 can be coupled to the crankshaft of the internal combustion engine, the crankcase of which is to be vented. It is also possible to couple the rotor shaft 6 with an oil centrifuge or with an electric motor.
