Definitions
- the present invention relates to a rotor for a centrifuge, in particular for cleaning the lubricating oil of an internal combustion engine, wherein the rotor is rotatably drivable in a centrifuge housing about a rotational axis, wherein the rotor is designed with a dirt collecting portion, radially outwardly bounded by a peripheral wall dirt catching part , Wherein the rotor as a whole or its dirt-catching part is made of plastic, wherein in the interior of the dirt-catching part a plurality of circumferentially spaced apart guide walls are arranged and wherein the rotor as a whole or its dirt-catching part can be removed from the centrifuge housing for maintenance purposes.
- Centrifuges and. used therein rotors for the purification of liquids eg. As for cleaning the lubricating oil of an internal combustion engine, have been used for decades. in use and are therefore known.
- the objective is to accelerate the liquid entering the dirt trap part as loss-free as possible to the angular velocity of the rotating rotor and, conversely, to return the swirl energy of the liquid as far as possible to the rotor during the outflow of the liquid from the dirt trap part.
- These are generally Baffles arranged in the waste collecting part, which extend radially or helically and reduce the slip between the liquid and the rotor and in this way both in terms of achievable rotor speeds and in terms of the relative velocity of the liquid relative to the deposited in the waste trap dirt particles conditions improve the separation of the dirt particles. In rotors made of sheet metal, this function is usually realized by the baffles forming imprints on one or both faces of the rotor.
- a disadvantage of the use of rotors or dirt traps made of plastic is that the strength of plastics is significantly lower than that of metallic materials. This disadvantage is particularly evident when, as is often necessary from 'given space requirements, the rotor or the dirt trap part must have an axially compact design with large outer diameter.
- a further problem is that, especially in the filling phase of the rotor or dirt-catching part during the start-up phase of the centrifuge, an uneven filling of the individual, separated by the guide walls, occurs. separated chambers can not be excluded. This uneven filling 'of the chambers is associated with an imbalance and as a result with reduced rotor speeds, vibration acceleration and noise emission.
- the object is to provide a rotor of the type mentioned above, which avoids the disadvantages set forth and in particular when using plastic as a material high mechanical strength and good durability and a good concentricity without imbalance economic manufacturability are ensured.
- That the rotor or its dirt trap part consists of a lower part and a shell
- the rotor characterized in that the rotor consists of a lower part and an upper part, in each of the lower and upper Leitwandmaschine are integrated and which are tightly strig Chartt each other, an economical production of the rotor or its dirt trap part is made possible. par- dere by the fact that the baffle parts are included in the weld, a particularly firm cohesion of the two rotor parts is achieved, resulting in a mechanically particularly resistant and permanently resilient rotor or dirt catching part without the risk of damaging deformations during operation.
- the breakthroughs also provided according to the invention provide for a uniform filling of all chambers formed by the guide walls in the rotor or dirt trap part, especially during the start-up phase of the centrifuge, so that even in this critical operating phase a good concentricity of the rotor is guaranteed without disturbing and harmful imbalances.
- the weld is in a direction perpendicular to the axis of rotation joining plane.
- a further embodiment proposes that the lower guide wall parts and the upper guide wall parts extend congruently to one another over their full length on their end faces facing the respective other guide wall parts.
- the baffle parts can be welded together in the context of welding between the lower and upper part over relatively large areas, so that they make a correspondingly large contribution to a high dimensional stability of the rotor.
- the lower guide wall parts and / or the upper guide wall parts are formed on their front side facing the respective other guide wall parts with a meshing or serrated structure pointing in the axial direction.
- the invention proposes that the comb-shaped or tooth-shaped structures of guide wall parts adjacent to one another in the circumferential direction have an offset in the radial direction relative to one another. With this offset ensures that seen in the circumferential direction of the rotor no continuous flow paths can form for the liquid in the rotor. This ensures effective entrainment of the liquid during rotation, in particular acceleration, of the rotor. In addition, high relative velocities between the liquid in the rotor and the already deposited dirt particles are avoided, so that a rinsing of already deposited dirt particles is avoided.
- a preferred further embodiment proposes that the number of baffles is even, that the comb or jagged structures form a regular grid with a grid spacing A and that the offset corresponds to half the grid spacing.
- a liquid-permeable opening is always opposite a liquid-impermeable comb teeth or serrations, whereby the desired inhibition of flow paths passing through in the circumferential direction is reliably effected.
- the comb or tooth-shaped structure is provided only in the lower part. In this embodiment, only the lower part of the slightly more complex geometry with the comb or jagged structure of the lower Leitwandmaschine arranged here, while the upper part can be performed with simple smooth end faces of its baffles.
- the lower baffle parts seen in the circumferential direction have a greater wall thickness than the upper baffle parts. It can be increased with a relatively low overhead of material, the wall thickness of the lower Leitwandmaschine. As a result, the comb teeth or teeth of the comb or jagged structure obtain a high strength, which protects them from damage, as long as the lower part is not yet welded to the upper part. In addition, small positioning inaccuracies in the circumferential direction during welding of lower part and upper part of the rotor or dirt trapping part can be compensated by this increased wall thickness, since there is still a sufficient surface for the welded connection between the lower and the upper Leitwand? remains.
- the rotor provides that the lower baffle parts and the upper baffle parts have at their respective other baffle parts facing end side over a part of its length a different course.
- the desired openings which connect the chambers in the waste collecting part, easily formed in the areas in which the end faces of the upper and lower Leitwandmaschine differ in their course from each other so that they are not interconnected.
- the lower baffle parts and / or the upper baffle parts are formed at least in the region of their front side facing the respective other baffle parts with a wave-shaped or zigzag-shaped structure pointing in the radial direction.
- each one of the baffle parts has the wave or zigzag structure. If both guide wall parts are structured accordingly, a weaker structuring of each guide wall part is sufficient, which can be advantageous in terms of production technology.
- the wave-shaped or zigzag-shaped structures of guide wall parts adjacent to one another in the axial direction have an offset in the radial direction relative to one another.
- the end faces of the guide wall parts adjacent to one another in the axial direction cross over in this way, preferably several times, whereby in addition to a plurality of apertures, a plurality of welding regions are also provided between the upper and lower guide wall parts at their intersections.
- the wavy or zigzag-shaped structures each form a regular shape with a wavelength A and the offset corresponds to half the wavelength.
- the number of baffles in the rotor according to the invention is six or eight or ten, wherein quite generally the number of baffles with increasing size, in particular with increasing diameter of the rotor, should be greater to the desired stability of the rotor even at high speeds and high densstechnikstem- temperatures, such as B. occur in the lubricating oil of an internal combustion engine, to ensure.
- the lower guide wall parts are integrally formed with the lower part and the upper Leitwandmaschine integral with the upper part and that the lower part and the upper part is in each case an injection molded part.
- the rotor or its dirt trap part can be designed without a radially inner annular wall or with a radially inner annular wall.
- the guide wall parts end freely radially in each case in an axially extending edge and that the edge is designed in each case with a stiffening thickening.
- the thickening of the edge in each case ensures sufficient stabilization of the free edge, so that no damage in the operation of the centrifuge are to be feared, even if here the Leitwandmaschine and the guide walls formed therefrom radially not connected to another area of the rotor or the dirt trap part are.
- the invention proposes that the baffles pass radially inward into the radially inner annular wall in one piece or engage in this form-fitting or non-positive or toast them.
- radially acting forces between the inner ring wall and the baffles can be transmitted, which is advantageous for the stability of the rotor.
- With a corresponding design of the rotor or dirt catching part can be dispensed with this transfer of radial forces, so that it is sufficient if the baffles radially inwardly abut only on the radially inner annular wall.
- a further advantageous measure for increasing the stability and load capacity of the rotor is that in the lower part and / or in the upper part seen in the circumferential direction between the lower and / or upper baffles one or more ribs are arranged, extending from the peripheral wall radially inwardly extend and are radially shorter than the baffle parts.
- these ribs also ensure that the liquid in the rotor or the dirt trap part is entrained when the rotor starts up and when the liquid enters the rotor.
- the ribs ensure a secure hold of the centrifugal forces radially outwardly deposited dirt particles, which are deposited between the ribs and between ribs and baffles and thereby effectively protected from rinsing by the liquid flowing through the rotor or dirt trap part.
- the invention proposes that the lower part has a smaller axial height than the upper part, wherein the height of the lower part is preferably between 20 and 50% of the height of the upper part.
- This refinement has the advantage that the apertures lying at the level of the weld joint are formed in the guide walls in a lower region of the interior of the rotor or dirt trap. partly come to lie, which is favorable for an early uniform filling of the chambers between the baffles.
- a transfer of liquid from the chambers, which are already filled higher, into the chambers, which are not yet filled up to the level of the openings with liquid for a good concentricity of the rotor or dirt trap part, it is advantageous to achieve the compensation of the liquid level in the individual chambers as early as possible. This is effected with the lowest possible arrangement of the openings in the rotor or dirt trap part.
- the lower part and the upper part are each formed on their peripheral wall with a welding flange. If the lower part and the upper part are designed radially inside without ring wall, the welding flanges are provided only on the radially outer peripheral wall of the lower part and upper part; in execution of the lower part and upper part with a radially inner annular wall, it is possible to provide here also on the lower part and upper part each have a welding flange.
- the welded joint is preferably a weld joint produced by light welding or mirror welding.
- the plastic of which the lower part and the upper part are made is preferably polyamide, since this material meets both the mechanical and thermal requirements is sufficient and at the same time relatively inexpensive and good sprayable and weldable.
