One in the 1 to 4 shown as a whole with 100 designated separating device For example, it is used for separating aerosols during machining of material in mechanical engineering and / or for separating oil mist from a gas stream.

The separation device 100 is used in particular for separating oil mist from blow-by gases of an internal combustion engine.

The separation device 100 includes a housing 102 which has an interior 104 the separator 100 surrounds.

The housing 102 For example, is formed in two parts, so that the interior 104 in particular for mounting the separation device 100 is easily accessible.

By means of a connection section 106 and a (not shown) screw connection and / or welded connection, in particular by a friction welding method (for example, a vibration, rotation or ultrasonic welding method) or a hot gas welding process, the two parts of the housing 102 in particular for easy assembly of the separation device 100 be connected to each other.

One in the area of the connection section 106 arranged seal 108 of the housing 102 prevents unwanted leakage of gas and / or liquid from the interior 104 the separator 100 in the assembled state of the separator 100 ,

The interior 104 the separator 100 is in particular substantially cylindrical and serves to receive a stack 110 from flow elements 112 ,

The flow elements 112 are substantially disc-shaped and each have an example circular central opening 114 on.

By means of the central openings 114 the flow elements 112 is a central channel 116 in the pile 110 from flow elements 112 educated.

The central channel 116 is substantially cylindrical and thus rotationally symmetrical about an axis of symmetry 118 which is a central axis 120 the flow elements 112 is.

In the in the 1 and 4 illustrated assembled state of the separator 100 is the stack 110 from flow elements 112 around the central axis 120 rotatable. The central axis 120 is thus an axis of rotation 122 the flow elements 112 , in particular the stack 110 from flow elements 112 ,

In a parallel to the central axis 120 running direction is the stack 110 from flow elements 112 on both sides with one end plate element each 124 limited. The end plate elements 124 each comprise a contact section 126 with which the end plate elements 124 at the flow elements 112 abut, and a storage section 128 with which the end plate elements 124 rotatable on the housing 102 are stored.

One of the flow elements 112 facing side 125 of each end plate element 124 has a shape which is the shape of the end plate element 124 opposite side 150 . 152 one to the respective end plate element 124 adjacent flow element 112 equivalent.

One of the end plate elements 124 is part of an inlet section 130 the separator 100 ,

Through the inlet section 130 can the interior 104 , in particular the central channel 116 of the pile 110 from flow elements 112 , For example, be supplied to an aerosol.

The other of the end plate elements 124 includes a drive section 132 , in particular a drive shaft 134 , by means of which the end plate element 124 and thus also the stack 110 from flow elements 112 with a drive device 136 can be coupled or coupled.

By means of the drive device 136 can over that the drive section 132 having end plate element 124 in particular a rotational movement on the stack 110 from flow elements 112 be transmitted.

In the in the 1 and 4 illustrated embodiment of the separation device 100 include the end plate elements 124 also each a connecting section 138 by means of which the end plate elements 124 through the central channel 116 are connectable through.

In particular, it is provided that a central connecting element 139 For example, a screw or threaded rod 140 , from the connection section 138 of the one end plate element 124 up to the connecting section 138 the further end plate element 124 extends and the Endplattenelemente 124 pull or push each other. The flow elements 112 thus become between the end plate elements 124 clamped.

The housing 102 the separator 100 includes a drainage opening 142 through which the means of the separator 100 separated fluid, in particular oil, from the interior 104 can be removed, in particular can drain.

Furthermore, the housing comprises 102 the separator 100 an outlet section 144 through which the means of the separator 100 cleaned gas the interior 104 the separator 100 can leave.

As in particular the 2 and 3 can be seen, includes each flow element 112 a substantially disk-shaped, at least approximately around the axis of rotation 122 rotationally symmetrical basic body 146 , which has a plurality of parallel to the central axis 120 extending walls 148 is provided.

Both a first page 150 as well as one of the first page 150 opposite second side 152 of the basic body 146 is there with such walls 148 Mistake.

By means of the walls 148 are channels 154 the flow elements 112 educated.

The walls 148 are thus partitions 156 between the channels 154 ,

The basic body 146 opposite free ends 158 the partitions 156 are as protrusions 160 educated.

The area of the main body 146 between the partitions 156 is a canal floor 162 of the channels 154 ,

The channel bottoms 162 are with depressions 164 , for example grooves 166 , Mistake.

The wells 164 or grooves 166 form recording sections 168 for the projections 160 ,

The recording sections 168 , especially the wells 164 or the grooves 166 , are preferably tapered in a depth direction. The recording sections 168 For this purpose, preferably comprise draft angles 165 or insertion bevels 167 , which are inclined to the central axis 120 are aligned.

The draft angles 165 or the insertion bevels 167 in particular by side walls of the receiving sections 168 educated.

The projections 160 are preferably to their the body 146 opposite end 158 formed tapering, in particular substantially complementary to the shape of the receiving portions 168 ,

Due to the tapered configuration of the receiving sections 168 and the projections 160 can the flow elements 112 positioned particularly accurately relative to each other and stable and reliable interconnected.

Both the first page 150 as well as the second page 152 of the basic body 146 is with such protrusions 160 and such receiving sections 168 Mistake.

The projections 160 and the receiving sections 168 are arranged distributed in such a way that with a simple stacking of identical flow elements 112 the projections 160 on the first page 150 a flow element 112 in the receiving sections 168 on the second page 152 another flow element 112 intervention. At the same time preferably grip the projections 160 on the second page 152 the further flow element 112 in the receiving sections 168 on the first page 150 of the first flow element 112 one.

The partitions 156 , the channels 154 , the projections 160 and the receiving sections 168 have a substantially Kreisvolventenverlauf.

Thus, circle involute channels 154 formed, extending from one of the central opening 114 facing inner end 170 up to one of the central opening 114 opposite outer end 172 extend.

By means of the channels 154 thus can through the inlet section 130 supplied aerosol from the central channel 116 in relation to the central axis 120 radial direction 174 be led to the outside.

The separation device described above 100 works as follows:
By means of the drive device 136 becomes the pile 110 from flow elements 112 over the drive section 132 of the end plate element 124 set in rotation.

The stack 110 from flow elements 112 acts as a centrifuge, by means of which heavy components, in particular droplets, of an aerosol can be deposited.

The aerosol, which is designed, for example, as a blowby gas of an internal combustion engine, is conveyed via the inlet section 130 the separator 100 through the inlet section 130 facing arranged end plate element 124 passed through and the central channel 116 of the pile 110 from flow elements 112 fed.

At the inner ends 170 of the channels 154 the aerosol enters the channels 154 one and gets through the channels 154 in the radial direction 174 to the outer ends 172 of the channels 154 guided. Due to the rotation and the shape of the channels 154 a separation of the droplets of the aerosol takes place on the partitions 156 , The droplets eventually become radial 174 in the direction of the housing 102 accelerate and then sink to the ground.

About the drainage opening 142 can the thus separated liquid, especially oil, from the interior 104 the separator 100 be removed.

The gas released from the oil leaves the interior 104 over the outlet section 114 of the housing 102 the separator 100 ,

By means of the described separation device 100 Thus, in particular, a droplet-laden gas stream can be cleaned.

As an alternative to the above-described mode of operation, provision may also be made for the separating device 100 in the reverse direction, for example, flows through an aerosol.

The aerosol then flows on as the outlet section 144 designated portion of the housing 102 the separator 100 in the interior 104 one. Through the channels 154 the aerosol then flows counter to the radial direction 174 from outside to inside to the central opening 114 , While flowing through the channels 154 heavier components, in particular droplets, of the aerosol are separated, so that a purified gas flow through the central channel 116 and as the inlet section 130 designated section from the interior 104 of the housing 102 the separator 100 can be removed.

Also in this mode of operation of the separation device 100 The separated components of the aerosol are passed through the drainage opening 142 from the interior 104 of the housing 102 away.

One in the 5 to 13 illustrated second embodiment of a separation device 100 is different from the one in the 1 to 4 illustrated first embodiment essentially in that for connecting and receiving the stack 110 from flow elements 112 a functional component 200 is provided.

The functional component 200 serves for the immediate admission of the stack 110 from flow elements 112 and driving the same.

The functional component 200 includes a shaft for this purpose 202 and a drive element 204 ,

As in particular the 6 to 9 it can be seen, is the functional component 200 integrally formed.

The functional component 200 is in particular as a plastic component 206 , in particular an injection-molded plastic component 208 , educated.

The wave 202 includes two ends 210 to which the stack 110 from flow elements 112 fixed or fixed.

A the drive element 204 facing the end 210 is with a coupling device 212 Mistake.

The coupling device 212 comprises a coupling element 214 the wave 202 and a coupling element 216 of the pile 110 from flow elements 112 ,

By means of the coupling elements 214 . 216 is in particular a positive and torque-transmitting connection between the shaft 202 and the pile 110 from flow elements 112 produced.

The coupling element 214 the wave 202 is for example by one or more radial projections 218 the wave 202 educated.

For example, the coupling element 214 one perpendicular to a rotation axis 122 The shaft taken in essentially square cross-section.

The coupling element 216 of the pile 110 from flow elements 112 is in particular a substantially complementary to the coupling element 214 the wave 202 trained receptacle or recess (see in particular 10 ).

The coupling element 216 of the pile 110 from flow elements 112 is in particular in an end plate element 124 of the pile 110 from flow elements 112 educated.

A the drive element 204 opposite end 210 the wave 202 includes, for example, a receiving section 220 for receiving the stack 110 from flow elements 112 ,

The recording section 220 is preferably at least partially with a thread 222 , in particular an external thread provided.

By means of a fastening nut 224 can thus be on the shaft 202 deferred stacks 110 from flow elements 112 on the wave 202 be screwed.

The stack 110 from flow elements 112 is in particular between the coupling device 212 and the receiving section 220 the wave 202 trapped.

In particular, the stack 110 from flow elements 112 thus between the two ends 210 the wave 202 trapped.

One between the two ends 210 the wave 202 arranged train section 226 the wave 202 is claimed to train.

In this train section 226 which is tapered towards its center, for example, comes the stack 110 from flow elements 112 preferably not with the shaft 202 in contact. Rather, the train section runs 226 preferably free within the central channel 116 of the pile 110 from flow elements 112 ,

That the drive element 204 opposite end 210 the wave 202 is also preferably further with a bearing section 228 provided on which a warehouse 230 for rotatably supporting the shaft 202 including the stack arranged thereon 110 from flow elements 112 in the assembled state of the separator 100 attacks.

Another storage section 228 the wave 202 is preferably between the drive element 204 and the coupling element 214 arranged so that here too a warehouse 230 can attack.

In the in the 5 to 13 illustrated second embodiment of the separation device 100 is the stack 110 from flow elements 112 thus rotationally fixed to the functional component 202 fixed and rotatable by means of a housing 102 the separator 100 stored.

For sealing the clean gas-carrying areas of the raw gas-carrying areas of the separator 100 is preferably a sealing device, for example a sealing ring 232 , intended.

The sealing ring 232 is in particular an O-ring, which in a trained as an annular groove sealing ring receptacle 234 the wave 202 is arranged.

The sealing ring 232 in particular seals a contact area between the shaft 202 and the pile 110 from flow elements 112 off, so that along the shaft 202 in the area of the drive element 204 facing end 210 the wave 202 a leakage flow is prevented.

As in particular the 7 to 9 it can be seen, is the drive element 204 in particular a turbine 236 , For example, a free-jet turbine 238 and / or a diagonal turbine 240 ,

The drive element 204 is in particular as a diagonal turbine wheel 242 educated.

The drive element 204 includes several blades 244 which is in a circumferential direction 246 relative to the axis of rotation 122 are arranged evenly distributed.

In particular 9 it can be seen, one is with blades 244 provided drive side 248 of the drive element 204 designed so that the entire surface of the drive side 248 unhindered in a direction parallel to the axis of rotation 122 extending axial direction 250 is accessible.

The shovels 244 are only slightly radially outward and in the circumferential direction 246 formed curved.

In addition, the blades extend 244 starting from a radially outer area 252 in the radial direction 174 inward as well as in the axial direction 250 ,

By means of the blades 244 are thus deflection channels 254 of the drive element 204 formed, which is a deflection or deflection of a fluid jet 256 enable.

The fluid jet 256 is in particular tangential to the radially outer region 252 the blades 244 of the drive element 204 directed.

The fluid jet 256 lies before its impact on the drive element 204 in a direction perpendicular to the axis of rotation 122 extending level.

By means of the drive element 204 becomes the fluid jet 256 deflected out of this plane, especially in the axial direction 250 diverted.

In particular 8th it can be seen, is the fluid jet 256 by means of the drive element 204 thus deflectable by about 90 °.

In particular 5 it can be seen, is the fluid jet 256 then simply in sequence at a lower end of a drive chamber 258 in which the drive element 204 is arranged, removable. An inefficient deflection of the fluid jet 256 on walls of the drive chamber 258 can be avoided.

The fluid jet 256 is by means of a blasting device 260 the separator 100 produced.

The blasting device 260 uses to generate the fluid steel 256 in particular engine oil of an internal combustion engine, which is guided for example under a pressure of about 6 bar.

The fluid jet 256 is thus in particular an oil jet 261 ,

As already described, the stack becomes 110 from flow elements 112 between the two ends 210 the wave 202 clamped or clamped.

The flow elements 112 thus become within the stack 110 relative to each other, in particular as regards the 1 to 4 already described.

Like that 11 to 13 it can be seen, the flow elements 112 alternatively or additionally be locked together.

Preferably, each flow element comprises 112 a locking device 262 ,

The locking device 262 includes several locking elements 264 and several snap shots 266 ,

In this case, each flow element comprises 112 several, for example three, locking elements 264 and several, for example, three, Rastaufnahmen 266 ,

The locking elements 254 For example, are designed as latching hooks and protrude substantially parallel to the axis of rotation 122 from the main body 146 path.

The locking elements 264 are integral with the body 146 educated.

Both the locking elements 264 as well as the rest shots 266 are evenly distributed on a radially outer edge 268 of the flow element 112 arranged.

In particular, the locking elements 264 and the rest shots 266 arranged alternately, so that in each case on a latching element 264 a snap-in recording 266 and then again a locking element 264 follows, etc.

One side of the flow element 112 on which the locking elements 264 extend is a locking element side 270 of the flow element 112 ,

The corresponding further side of the flow element 112 is a snap-in side 272 of the flow element 112 ,

As in particular the 11 and 12 it can be seen, are the flow elements 112 stackable on each other so that in each case one locking element side 270 a flow element 112 to a detent receiving side 272 another flow element 112 borders.

The locking elements 264 a flow element 212 embrace the further flow element 112 doing so from the detent side 272 here at his rest shots 266 ,

The identical flow elements 112 just have to do this around the axis of rotation 122 be arranged rotated relative to each other, so that the locking elements 264 with the in the circumferential direction 246 offset latching recordings arranged 266 the further flow element 112 can be brought into engagement.

In the 11 to 13 are only two flow elements 112 represented, which by means of the locking device 226 locked together.

However, it is obvious that a variety of other identical flow elements 112 can be stacked in the same way, ultimately the stack 110 from a variety of flow elements 112 manufacture.

By means of the locking device 262 of each flow element 112 can be a pre-assembled stack 110 from flow elements 112 to be provided.

In particular, it may be provided that also end plate elements 124 of the pile 110 from flow elements 112 with locking elements 264 and / or snap shots 266 are provided to the end plate elements 264 with the flow elements 112 according to the 11 to 13 latching together can connect.

The whole pile 110 from flow elements 112 including end plate elements 124 is then as a preassembled unit on the shaft 202 of the functional component 200 pushed.

The coupling element 216 of the one end plate element 124 can do this on the coupling element 214 the wave 202 be deferred, allowing a non-rotatable connection between the stack 110 from flow elements 112 and the wave 202 of the functional component 200 is guaranteed.

The sealing ring 232 in the sealing ring receptacle 234 seals the shaft 202 opposite the stack 110 from flow elements 112 from.

By screwing on the fastening nut 224 on the thread 222 the receiving section 220 can then the entire stack 110 from flow elements 112 between the ends 210 the wave 202 be trapped.

Incidentally, the right in the 5 to 13 illustrated second embodiment of a separation device 100 in terms of structure and function with in the 1 to 4 illustrated first embodiment, so that reference is made to the above description in this respect.

In the 14 to 16 is an alternative embodiment of a drive element 204 shown, which is different from the drive element 204 according to the in 5 to 13 illustrated second embodiment essentially differs in that the drive element 204 as one of the wave 202 various component may be formed.

The drive element 204 is therefore not part of a one-piece functional component 200 but rather with a separate wave 202 connectable.

The drive element 204 includes, for example, an internal bearing section 228 for rotatably supporting the drive element 204 ,

Furthermore, the drive element comprises 204 according to the in 14 to 16 illustrated embodiment in addition to a drive side 248 a support page 274 which is the mechanical support and stabilization of the drive element 204 serves.

In particular, the support side comprises 274 one or more support elements 276 , for example, struts 278 and / or webs 280 ,

Incidentally, the right in the 14 to 16 illustrated alternative embodiment of a drive element 204 in terms of structure and function with in the 5 to 13 illustrated embodiment of the drive element 204 so that reference is made to the above description in this respect.

That in the 14 to 16 illustrated drive element 204 may alternatively be one of the aforementioned drive elements 204 be used.

One in the 17 to 21 illustrated third embodiment of a separation device 100 is different from the one in the 5 to 13 illustrated second embodiment essentially in that the determination of the stack 110 from flow elements 112 on the wave 202 not with a screw, but by means of a fastening device 282 takes place, which as a clip device 284 is trained.

The stack 110 from flow elements 112 is thus in particular between the coupling device 212 and the clip device 284 clamped.

As in particular the enlarged view in the 19 to 21 can be seen, includes the clip device 284 one or more clip elements 286 , which, for example, as a latching hook 288 are formed.

The one or more clip elements 286 are with one or more clip shots 290 engageable.

In the in the 17 to 21 illustrated third embodiment of the separation device 100 is a single clip recording 290 provided, which as a circumferential groove 292 in the receiving section 220 the wave 202 is arranged.

As in particular the 20 and 21 it can be seen, is the receiving section 220 the wave 202 essentially conical and against a mounting direction 294 formed rejuvenating.

The mounting direction 294 is in particular that direction in which the stack 110 from flow elements 112 on the wave 202 is deferrable.

Also the stack 110 from flow elements 112 , in particular an end plate element 124 , which in the assembled state of the separator 100 on the receiving section 220 the wave 202 comes to rest, comprises a substantially cone-shaped receiving portion 296 which opposes the mounting direction 294 is formed tapering.

The recording section 220 the wave 202 and the receiving section 296 of the pile 110 from flow elements 112 are formed substantially complementary to each other. This allows a simple centering and secure fixing of the stack 110 from flow elements 112 on the wave 202 be guaranteed.

In addition, by the conical configuration, a simple deflection of the clip elements 286 be initiated from a rest position, so that this at a Rashemindernis 298 the wave 202 be moved past and into the groove 292 can engage.

Incidentally, the right in the 17 to 21 illustrated third embodiment of a separation device 100 in terms of structure and function with in the 5 to 13 illustrated second embodiment, so that reference is made to the above description in this respect.

A determination of the stack 110 from flow elements 112 by means of the clip device 284 according to the in 17 to 21 illustrated third embodiment is particularly advantageous when the flow elements 112 of the pile 110 from flow elements 112 already by means of locking devices 262 connected to each other and the stack 110 from flow elements thus already exists as a preassembled unit.

The entire operation of the separation device 110 rotating unit of functional component 200 and stacks 110 from flow elements 112 can then be particularly easily manufactured and assembled by that first the functional component 200 as an injection molded plastic component 208 will be produced. Also the end plate elements 124 and the multiple flow elements 112 are preferably used as injection molded plastic components 208 produced.

Subsequently, the flow elements 112 with each other and with the end plate elements 124 latched to the stack 110 from flow elements 112 finish.

After that, all that's left is the stack 110 from flow elements 112 on the wave 202 of the functional component 200 be deferred until the clip elements 286 in the groove 292 on the wave 202 engage.

In further (not shown) embodiments of separation devices 100 may be one or more features of the separation devices described above 100 be combined with each other.

For example, a diagonal turbine wheel 242 trained drive element 204 for driving the flow elements 112 according to the in 1 to 4 illustrated first embodiment can be used.
