Definitions
- the invention relates to a rotor which is particularly suitable for installing the housing of a free jet centrifuge.
- Such rotors are e.g. B. is known from DE OS 1 532 699.
- a rotor for a centrifugal cleaning device with a hollow hub, via which the liquid to be cleaned is supplied with inlet openings which are connected to the interior of a rotor chamber, the liquid being from one end of the interior of the rotor chamber escapes via one or more reaction nozzles which are arranged in such a way that the rotor is set in rotation, the interior of the rotor being divided into two chambers by an annular partition wall, namely into a relatively large inlet chamber, with which the inlet openings communicate and a relatively small outlet chamber to which the nozzles are connected, and the inlet chamber and the outlet chamber being connected to one another by an overflow channel which encloses the hollow hub at a small distance.
- Such a device is heavy and expensive to manufacture.
- a rotor for a laboratory centrifuge which has several plastic injection molded parts, and which has a symmetry to a vertical axis, which simultaneously forms the axis of rotation, in such a way that it is circumferentially aligned in several in its construction identical sectors is subdivided, the sectors having a plurality of radial and circumferential webs and surface parts, which has a plurality of receptacles for sample tubes which run radially and at an angle to the axis of rotation.
- Such a device is not suitable for use as a flow-through centrifuge.
- EP A2 608 519 Also known from EP A2 608 519 is a rotor which contains a pliable plastic container for receiving red blood cells, which has a metal rotor housing receptacle which absorbs the static forces.
- the main focus is on creating a removable, biocompatible container for holding human secretions to be centrifuged, in particular, for. B. the separation of red blood cells and plasma, the separated blood cells are then removed and cleaned.
- This device has a very limited field of application with regard to the media to be centrifuged.
- a disadvantage of the known devices of the type mentioned at the outset is that they are heavy, expensive and unsuitable for high throughput rates and cannot be used for cleaning, for example, an engine oil flow with the correspondingly high temperatures.
- the object is achieved by a rotor with at least one inlet and at least one outlet for the medium to be centrifuged, the rotor having at least one bearing point for receiving a bearing element and consisting essentially of self-supporting plastic.
- the rotor is normally installed in a housing of a free jet centrifuge intended for this purpose. But it is e.g. B direct installation into the oil sump of an internal combustion engine is also conceivable. A weight reduction effect can be achieved by using plastic. In addition, the use of e.g. B. injection molded parts also have a significant cost advantage. Plastics of today's provenance have made them suitable for everyday use. They are able to endure high temperatures of up to around 140 ° C., as is the case, for example, with motor oil, especially in extreme operating conditions of the corresponding internal combustion engine, in which such a centrifuge can be used.
- plastic as a material offers another significant advantage. This makes it possible to provide guide elements inside the rotor from an economically justifiable point of view.
- the medium to be centrifuged is forcedly guided depending on the rotor speed makes it possible to set a defined separation limit with regard to the particles to be separated.
- this version is not so economical to manufacture.
- outlets in the rotor designed as nozzles ensure an outflow of the fluid in the tangential direction with respect to the axis of rotation of the centrifuge.
- the outlets can be directed downward, whereby a force component counteracts gravity on the rotor, which relieves the bearings of the rotor.
- An advantageous development of the invention provides that the distance of the outlet from the axis of rotation is greater than the outer radius of the rotor. In this way it is ensured on the one hand that the exit medium from the Nozzle can actually emerge tangentially, which is an increase in performance compared to the prior art, on the other hand, the startup behavior is positively influenced and the operating speed is much more stable.
- stiffening elements are attached in the interior or on the outer wall of the rotor in the direction of the main stress axes. This counteracts the flow behavior of the plastic.
- the guide elements installed in the interior of the rotor also take on the function of stiffening.
- a sensible embodiment of the invention provides a ball bearing at least at one of the two bearing points of the rotor.
- the startup behavior of the turbine can be improved by this measure.
- the ball bearing can absorb the axial forces of the rotor, which fluctuate depending on the operating state of the centrifuges.
- the rotor housing has a centrifuge shaft as the bearing element.
- a shaft made of steel for example, a very precise-acting bearing is possible in connection with a centrifuge axis located in the housing and the corresponding bearings, so that the centrifuge can be used as a main flow centrifuge without an upstream or downstream oil filter.
- the rotor pot and the rotor base can advantageously be connected to one another by a snap connection. This simplifies assembly. Another possibility is to weld the rotor pot and rotor base.
- the vibration welding method is particularly suitable for this, but it is also e.g. the rotary welding process is conceivable.
- an impulse channel is provided in the motor base, which forms a connection between the rotor interior and the nozzle-shaped outlet.
- Figure 1 shows the side view of a free jet centrifuge
- FIG. 2 shows the cross section of the rotor
- FIG. 3 shows the section through a free jet centrifuge in the design with an all-plastic rotor along the central axis of the centrifuge
- FIG. 4 shows the view of the rotor base of a rotor according to FIG. 3.
- the rotor 1 shown in FIG. 1 has an inlet 3 and an outlet 4.
- the rotor housing has two bearing points 5.
- Guide elements 7, which are not shown in FIG. 1, are located within the rotor. These guide elements run radially with respect to the axis of rotation from an inner wall 38 to an outer wall 39 of the rotor.
- the rotor interior 8 is divided into different areas 9 by these guide elements.
- the actual rotor consists of a rotor base 10 and a rotor pot 11.
- the rotor is constructed rotationally symmetrically with respect to the axis of rotation 13. To increase the strength of the plastic rotor, this has stiffening elements 14.
- the guide elements 7 also take on a supporting function for the rotor pot 11.
- the stiffening elements have the shape of cooling fins on the outer circumference of the rotor housing and, in the case of an injection molding construction, must not exceed a certain wall thickness (here: 3-4 mm).
- the rotor 1 is accommodated in a housing 15, which in turn consists of an upper housing part 16 and a lower housing part 25.
- the centrifuge has an inlet 17 through which the medium to be centrifuged, in particular oil from an internal combustion engine, which is not shown here, get into the rotor chamber 8 in such a way that these media to be centrifuged reach inside the centrifuge shaft 19 or the centrifuge axis 20 up to the corresponding passage openings 6.
- the medium passes via the channel 34 directly to the inlet 3 of the rotor 1 and above it directly into the rotor interior 8.
- the medium is guided along the guide elements 7 until it then past the intermediate floor 26 via the path the outlet 4 of the rotor reaches the outlet 18 of the centrifuge, from where it is fed back to the lubricating oil circuit of the internal combustion engine, not shown.
- the rotor 1 is mounted in the centrifuge in cooperation with the centrifuge axis 20 and the bearings 23 and the washer 27, the centrifuge axis being connected to the upper housing part 16 in a torsionally rigid manner by means of a cone bracing by means of a nut 22 in cooperation with a centering bushing 21.
- Bearing bushes 23 are arranged between the centrifuge axis 20 and the hollow centrifuge shaft 19.
- the centrifuge shaft 19 carries the rotor cup 11 and the rotor base 10, these being braced centered on a conical receptacle of the hollow shaft by a washer 27 and a nut 29.
- Seals 24 are located between the centrifuge shaft 19 and the rotor housing to prevent leakage losses.
- a seal 28 compensates for unavoidable tolerances and settlements in the cone clamping of the Rotor housing and ensures that there are no undesirable short circuits between the rotor base 10 and the rotor cup 11.
- the seal 30 prevents the medium to be centrifuged from passing through an undesired short circuit past the rotor directly to the outlet 18 of the centrifuge.
- a press-in bushing 31 represents the second bearing receptacle for the centrifuge axis 20, which takes effect after assembly of the lower housing part 25 with its corresponding upper part 16.
- FIG. 2 shows a section through the rotor 1, in which the rotationally symmetrical structure of the rotor housing 2 with respect to the axis of rotation 13 becomes clear.
- the rotor 3 shows a rotor made entirely of plastic.
- the rotor 1 is constructed in three parts, it consists of the rotor pot 11 into which the guide elements 7 and the inner wall 38 are integrated, and the rotor base 10.
- a pulse channel 40 is embedded in the rotor base, which through a channel cover 36 forms a hollow cross section is closed.
- the impulse channel ensures the conduction of the medium from the rotor interior 8 to the nozzle-shaped outlets and thereby prevents the flow conditions at the outlet from washing out the resulting centrifuge cake.
- the channel cover can e.g. B vibration welded to the rotor base.
- the rotor has two bearing journals 32, 33 for receiving the bearings.
- the bearing journal 32 is closed, so that an oil short circuit is prevented.
- the rotor can thus be mounted in a ball bearing 34 in the upper part of the housing.
- the bearing journal 33 is open, which creates a connection between the inlet 17 in the housing and the inlet 3 in the rotor. The flow of the medium through the centrifuge can thus be carried out in the manner described in connection with FIG. 1.
- the bearing engaging on the journal 33 consists of a captive slide bearing 35.
- This slide bearing consists of a press-in bushing 2, which is preferably made of bronze, and a sliding bushing 12, which is preferably made of steel.
- the sliding bush has a shoulder 41 which prevents it from slipping out of the press-in bush 2 in the event of a rotor change.
- the upper housing part 16 is preferably made of plastic and is screwed into the lower housing part made of aluminum, sealing means 42 being used.
- the connection between the rotor pot 11 and the rotor base 10 is designed as a snap connection 37 in this exemplary embodiment. Sealants 42 can also be used here. Alternatively, the snap connection can have a self-sealing geometry. In the event that a welded connection is provided for the connection between the rotor pot base, the sealing means are also dispensed with.
- the central joint bottom 10 is shown in the embodiment with a snap connection 37.
- the structure that forms the impulse channel 40 in the rotor base This is shown in the state prior to the application of the channel cover 36. At the ends of this structure, the outlets acting as nozzles can be seen.
