Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has an axial inlet for inputting the material to be processed, a radial outlet for taking out the processed material, and a truncated conical inlet rotating inside the casing. and a rotor having coaxial rings of graduated diameter on the rotor mantle, each of these rings being staggered with respect to a like ring mounted on the stator facing the rotor. This invention relates to a rotor-stator machine consisting of a casing in which the ring has holes forming teeth. In this type of machine, the stator and rotor are equipped with shear force generating devices, such as tooth or rim devices, which mix the materials to be treated.
Diffused and homogenized. The facing surfaces of the rotor and stator are conically shaped and equipped with corresponding tools. The tool is formed by a convoluted groove with a cutting hole or a ring inserted into the groove. The original tools are cut into those rings.

In a machine such as that described in German Patent Application No. 2403053, several rotors and stator rings are each secured to each other by means of a number of screws. The rotor and stator tools must be manufactured with great precision so that they engage each other accurately. The installation and extension of the tool requires great skill on the part of the operator and is therefore subject to severe wear depending on the respective processing medium.If it is necessary to replace the ring, operation is interrupted for a long time. I will do it. This can be tolerated in normal use, even if it is a hindrance and an expense, but in continuous use, the rotor-stator machine carries out only one machining or treatment step in the entire process, and long interruptions are extremely difficult. This is a disadvantage, especially in the field of biotechnology.

In the case of microbiological processes, even greater disadvantages arise due to the state-of-the-art structure. This is because the various gaps and blind spots inside the machine are extremely dangerous in the case of microbiologically dangerous processes and sterility.

The object of the invention is to provide a rotor-stator machine having a construction particularly suitable for use in the field of biotechnology. This means, on the one hand, that product build-up and residue can occur inside the machine when used in microbiologically hazardous processes; it must be possible to avoid spillage, purify or clean the product, especially if the product This is the case when considering replacement, which on the other hand means that tool replacement due to wear must be possible in a short time without interrupting the entire process. A further need lies in the implementation of optimal treatment capabilities and methods with regard to shearing and homogenizing effects precisely in the case of highly sensitive microbiological processes. This was not guaranteed with technical aquatic machinery.

This section is made by the rotor-stator machine of this invention.
The stator, which forms part of the machine casing, is removable, and the rings supporting the actual tools are each located in a groove-like cutout, and these rings are connected to one adjacent ring and the stator, rotor, two The stator ring is formed in the stator and the rotor ring is formed in the rotor so as not to be twisted. This is solved by keeping the values relatively fixed.

Both the stator ring and rotor ring can be easily replaced after removing the stator. This prevents the rings from normally sticking in the grooves when the set of tools is configured according to the invention. This is because here a part of the groove surface is formed by the ring which is to be installed in turn.

The stator ring can be removed or replaced easily and quickly by removing the stator or casing cover by simple means and regardless of the need for accuracy. This is because the tools can be reached from anywhere. The same goes for rotoring. This is because the entire rotor can be pulled out from the shaft after loosening the screws. Such an arrangement greatly simplifies tool changes, resulting in significant time and cost savings. A particular advantage of the invention is that the proposed arrangement as described above only uses the outer ring to tighten the outer hestator ring from the inside, while the rotor cap is used to tighten the rotor ring from the outside in. just use it,
An easy and particularly fast replacement of worn parts is made possible, in particular by the fact that, after loosening the only central screw, the entire rotor can also be removed.

A decisive advantage for the installation of machines in the field of biotechnology with the inventive configuration of the ring is that the number of screws, gaps and blind spots, ie where deposits and scorching can occur, is reduced. This is necessary during microbiologically hazardous processes and product exchanges. In this way, the time required for cleaning and purification can be reduced, which is particularly effective when products are replaced frequently.

It is advantageous to shape the machine as follows: That is, looking at the several rings in the machine axis direction, align the centers by turning the stator or rotor in stages,
It is held in the axial direction by the lip. Interchangeability is thus considerably simplified and accelerated. This is because the stator rings are automatically centered between each other from the inside to the outside, increasing during operation and reducing the seams that hold the rings together. This also applies to rotor rings that are mutually centered from the outside to the inside.

In a special configuration, the tools are each attached on one side to the free end face of the ring, which ensures significant accuracy of the machining with regard to the effectiveness of the shearing process and simplifies the machining itself.

Special measures are taken to prevent the ring from twisting relative to the stator or rotor due to shear forces due to any load increase.

That is, the stator ring or rotor ring has holes on the load side, which holes correspond to the holes in the stator or rotor, respectively. Retaining pins are inserted into these holes.

On the stator side, the stator rings each have a lip on the outer diameter which allows each ring to move from the adjacent larger ring to the lip of the adjacent smaller ring or to the innermost side. In the case of a ring, the outermost stator ring is pressed against the mounting ring surface of the stator, and the outermost stator ring is fixed to the stator by an I+ set screw that generates a tightening force on the lip part of the outermost stator ring. The rings each have a lip on the inner diameter which allows each ring to be connected by an adjacent smaller ring to the lip of an adjacent larger ring;
If the machine is configured so that the outermost ring is pressed against the ring surface on which the rotor rests, and the innermost rotor ring is subjected to the clamping force for all rings, this is doubly true. It's advantageous.

These lips according to the invention allow one ring to be held axially by an adjacent ring, so that the rings do not have to be screwed all together on their own. This means fewer threads, gaps and blind spots, which favors faster and more thorough cleaning of the machine during product changes, and reduces tool change times due to fewer steps required.

The tightening force required for the rotor ring can be achieved by installing a rotor cap on the machine side end of the rotor shaft, resting the rotor cap on the lip of the innermost rotor ring with its ring surface, and fixing it with a screw provided in the center. It is particularly advantageous if a counter thread is applied to the innermost ring to create a clamping force on the rotor ring. This single fixing screw creates extremely favorable circumstances not only for shortening tool change times but also for sufficient cleaning of the machine.

The following configurations are useful for quick and reliable tool changes. That is, the stator is removably connected to the machine casing by a number of retaining screws, the collar of the casing is flush with the outer surface of the stator flange, and these retaining screws are larger than the arc of the fixing screws of the stator ring and The structure is such that it lies on an arc larger than the diameter. In this way, the installation during insertion is simplified by the guidance of the stator, which is also the casing cover.
Damage to the backing is prevented. In this configuration, the screws are on the outside of the backing and are sunk into the stator, making them easier to clean from the outside and more aesthetically pleasing.

The most difficult problem with respect to the requirements for adequate washing and cleaning of the machine is due to the gap between the back of the stator and the inner wall of the rear casing, which has functional and manufacturing limitations. At this point, all other efforts to avoid gaps and blind spots are wasted. In a special configuration, therefore, grooves are provided on the back side of the rotor. These grooves create an outwardly directed flow, so that the material present in the gap is constantly fed to the outside.

The time required for changing the tool is largely determined by the time required for removing and reinstalling the stator, which is designed as a casing cover. Especially when reinstalling the casing cutter,
This is difficult because, on the one hand, the holes in the casing cover and the threaded holes in the casing must be precisely aligned so that the fixing screws can pass therethrough, and on the other hand, the internal backing must not be damaged. Furthermore, at least in the case of large machines, a hoisting device is required for installing and removing the casing cover. These problems are solved by the inventive construction of a rotor-stator machine in the following way. That is, the stator, which is also the casing cover, is equipped with one or several guide bolts that slide axially inside the casing. These guide bolts form hinge flanges at their outer ends, which hinge flanges are rotatably supported in mutually aligned hinge bolts connected to the casing cover or the stator.

Due to this hinge fixation, the casing cover first remains in the casing recess 11 after loosening the fixing screw and does not come out. The operator can then remove the cover axially from the housing recess without special aids and turn the cover by means of the joint after a certain distance. The cover is then opened and the tools are freely accessible. The casing can be closed by reversing this order.

That is, turn the cover and then insert the guide bolt into the axial casing recess without damaging the backing.

Additionally, the joint guide always aligns the hole in the cover accurately with the screw hole in the casing, making it possible to insert the fixing screw without any problems.

Reliable opening and closing of the casing cover is achieved by guiding the guide bolt into a bearing fixed in an axially arranged hole. In this case, a stop device is provided in each case at the inner end of the guide bolt, the bearing for the pulled-out guide bolt serving as the stop element. Due to this special configuration, as long as the casing cover remains identified with the guide bolt, this guide bolt also remains fixed and remains connected to the casing during the continuation of the tool change.

In another embodiment of the invention, the hinge flange of the guide bolt engages in a recess in the casing cover or stator, and the holes in the hinge flange and the holes in the casing cover or stator are arranged one over the other for receiving the hinge bolt. do. A particularly advantageous arrangement is realized in that the inner side surface of the housing cover or the stator is provided with a recess for the introduction of each hinge port I. In order to make the construction of the hinge simple and space-saving, the hinge bolts are fixed in holes in the housing cover or in the stator with a brace fit.

In addition to ensuring fast and reliable handling during tool changes, the hinge provides maximum smoothness of the surface of the rotor-stator machine and eliminates uneven corners.

If the casing cover is small and light, two hinges are sufficient to securely close the casing cover without damaging the backing.

However, if the casing cover is large and heavy, accurate guidance during closing cannot always be guaranteed. Inserting the backing and fixing screws becomes a problem. Therefore, where necessary, the casing cover or the stator is provided with two hinges placed one above the other on one side, viewed in the axial direction, and a separate guide bolt serving only for guidance is provided on the opposite side. The insertion tip of the guide bolt can be conical to facilitate insertion into the guide hole.

In order to shorten the overall process time, the highest shearing and homogenizing capacities of rotor-stator machines are even more important in microbiological processes than in other fields of use. In principle, this can be facilitated by increasing the number of stages, teeth, rows of holes, number of holes, and narrowing the gap width. In some known machines, the tools are arranged as follows. That is, a gap is formed between the bottom surface of the recess and the top surface of the ring,
Due to their arrangement, these gaps ensure that the part of the material that exits the gap that runs from the machine input to the outlet is not machined by the tool.

In order to increase the efficiency of the configuration according to the above documents regarding stators and rotors, when rotor-stator machines are used in the field of biotechnology, the bottom of the stator or rotor rings should be deepened and the rings facing these recesses should be It has been proposed that the ring protrudes into the recess and the recess is configured to form a gap with different levels between the bottom surface and the opposing head surfaces. This configuration of the machine forces the processing material to change direction on its way from the input to the machine to the outlet at the corner of the tool.

In this way, it is ensured that no part of the particles passes without contact with the tool and thus without being processed from the input port to the removal port. Each baffle plate from ring stage to ring stage generates micro-eddy currents and corner repulsion with micro-voids.

In this way, and also with the creation of a stagnation effect, the efficiency of the machine is increased.

In a special configuration of the machine, the bottom surface of the ring and each opposing head surface are aligned parallel to each other and make a right or acute angle with the axis of the shaft, which may be advantageous depending on the various product and process requirements.

A further increase in shearing and homogenization efficiency is achieved by forming the tool as follows. That is, starting from the imaginary theoretical conical surface of the rotor, the head surface of the individual stator rings increases in each case from the outer ring to the axis of the shaft and is therefore shifted step by step, so that the respective [
1- This is possible if the recesses in the stator ring are correspondingly adapted to the stator ring.

From a production engineering point of view, it is particularly advantageous to design the rotor ring and the stator ring according to the invention in such a way that the bottom surface of the toothing is concave in the ring.

Since the reactions in microbiological processing are partially strongly temperature-dependent, in addition to the structural measures taken to improve the oxidation and homogenization effects, there are Further measures are taken to maintain the best possible temperature. That is, it is necessary to protect the medium from both heating and cooling. In addition, changes in the composition of the treated material must be prevented. Particularly important is the maintenance of this temperature during product changes, which makes it possible to set the correct temperature even initially, so that the initial steps are shortened and this contributes to increasing the efficiency of the entire process.

Therefore, as a special measure within the scope of the invention, an annular heat exchanger is provided in the region of the input pipe and the treatment material supply conduit.

When this heat exchanger is supplied with hot heating or cooling material, the machine is warmed up or cooled down even before it is put into operation, so that the material to be treated is kept in the sufficiently heated or cooled machine. I will be entering. The heat dissipated or absorbed during operation and the resulting cooling or heating are continuously compensated for via the heat exchanger. Thus, using the machine according to the invention it is possible to ensure that the temperature of the treated material is always the same and to shorten the starting period when changing products if the best temperature values for each product do not match. can. Furthermore, the viscosity of the treatment material can be adjusted by changing the temperature of the heat.

To simplify the process, and to make it possible to adapt the adjustment range of the heat exchanger when there are various products with significantly different temperature conditions and heat quantity conditions without any problems or in a particularly short time. For this purpose, the heat exchanger is constructed in accordance with the invention as consisting of an exchange chamber having supply and discharge ports for the exchange medium, and is arranged between the flange of the input pipe and the flange of the supply pipe in the axial direction.

In yet another configuration, the annular inner surface of the heat exchanger with the tubing section extends in the axial direction of the machine, with the tubing section possibly protruding from one or both sides of the heat exchanger to provide the necessary Depending on the heat exchange surface, the covering protrudes into the inlet pipe piece and/or the supply pipe. This configuration of the rotor-stator machine makes it possible to adapt to the best operating conditions over a wide temperature range fX. This is because, firstly, the heat exchange surfaces can be configured accordingly, and secondly, when there are widely different requirements, the standstill time of the rotor-stator machine can be extremely reduced and the heat exchanger can be easily and quickly constructed. This is because the entire process does not have to be interrupted because the parts can be replaced.

However, this measure not only improves and increases the heating or cooling of the machine, but also allows the effect to be exerted directly on the material to be treated.

Further details will be given based on figures showing examples.

The rotor-stator machine consists of a casing 2, a stator 8 which is also the tip of the casing 2, a rotor 3, and a ring.
It consists of 11.12. The ring is provided with tooth profiles or rim profiles, ie actual tools 25 and 26, for creating shear forces. Stator ring 1
1a, 11b, 11c, 11d are fixed on the stator 8, rotor rings 12a, I 2b, 12c,
12d is fixed on the rotor 3. The rotor 3 is driven via a shaft 4 by a motor (not shown). The input port for the material to be treated is designated by the reference numeral 5 and is constituted by a stator 8 and an input tube piece 7 adjoining the stator. The material outlet marked 6 transitions into an outlet tube piece 9 and a flange 10.

The casing 2 has an end cutout 5 on the side facing the shaft 4.
2, and the stator 8 forming the casing cover is inserted into this notch. The stator 8 is fixed to the pitch plane 31 by several screws 23, the sealing 40 to the casing taking place between the screws 23 and the seam 32 in the axial direction. The facing surfaces of the stator 8 and the rotor 3 are configured in stages to accommodate the stator ring 11 or the rotor ring 12.

The figure shows by way of example a rotor-stator machine having four stator rings and four rotor rings. The difference in the number of pieces is determined depending on the type and hardness of the treated material and the method of processing. Stator ring 11 a, l lb, I
Each of lc and 11d has a shoulder 15 on its outer diameter, and each ring is fixedly installed in the axial direction by these shoulders. This is because the adjacent larger ring rests on this shoulder and presses it against the shoulder of the next smaller ring. The innermost stator ring 11a rests on the receiving ring surface 13 of the stator 8. The clamping force for the entire stator ring 11 comes from the fixing screws 19. These fixing screws I9 are distributed around the periphery of the shoulder portion of the outermost stator ring 11d. Rotating ring 12a, I 2b, I 2c
, 12d are similarly clamped together, but each shoulder I6 is disposed along each inner diameter. That is, each adjacent smaller ring rests on this shoulder and pushes this ring onto the shoulder of the next larger ring.

I'm wearing it. The outermost stator ring 12d is connected directly or via one intermediate ring 33 to the rotor mounting annular surface 1.
It is listed in 4. The clamping force on the entire rotor ring 12 originates from a screw 22 screwed centrally into the sleeve 4 and passes through the annular surface 21 of the rotor cap 20 to the ring 12a and from there to the next ring 12b, I 2c, ! 2d to the rotor 3. Rotor 3 is shaft sleeve 2
Fixed to 4.

Stator ring I+ and rotor ring 12 are holding pins 17
and 18, which retaining pins are located on the stator side 29 and on the rotor side 30 in parallel holes 27 and 28, respectively.

Each inner end face of the rings 11 and 12 is provided with a hole or a tooth profile forming the actual tool 25 and 26 in the form of a tooth, so that these holes or tooth profile respectively are ring-shaped. They are staggered and interlock.

A gap 42 is formed between the back surface 35 of the rotor 3 and the inner wall surface 41 of the casing 2. This is for engineering reasons. A groove 36 is provided on the back surface of the rotor to prevent material from becoming trapped in this gap. These grooves form an outwardly directed flow section, so that the material that enters the gap always flows outwards. Therefore, no material is caught in this gap. The outwardly directed flow also has the advantage that the seal 43 between the shaft sleeve 24 and the rotor 3 is free of pressure.

In the embodiment shown in FIGS. 2 and 3, there are four grooves 36, which are radially straight away from the center of the rotor. Another configuration advantageous for manufacturing is at 771, which extends beyond the shaft hole 4a. The number of grooves depends on the type and composition of the treated material,
It is preferable to use 2, 3, 5, 6 or more depending on the hardness. It is also advantageous for the grooves to be positioned at an angle to the radial direction or curved, depending on the intended use.

In the examples shown in FIGS. 4 to 6, a casing cover forming the stator 8 is shown. This housing cover forms a unit with the block flange and can be inserted into the recess 52 of the housing 2. Between the housing 2 and the housing cup or stator 8 there is a seal 40 .

Stator 8 is fixed in casing 2 by screws 23. These screws are inserted through the opening 53 of the stator 8 and screwed into the screw holes 54 of the casing 2. For easy opening and closing of the casing cover or stator 8, a hinge 5I is provided, which allows the stator 8 to be rotated after removal of the fixing screws 23. The hinge 51 consists of a guide bolt 37 with a hinge flange 38 and a hinge bolt 39, which is mounted inside the housing 2. This hinge bolt is firmly connected to the casing cover or stator 8. The guide bolt 37 is axially slidably mounted in a bearing 45 in a bore 44 of the housing 2 parallel to the longitudinal axis of the machine. In order to enable this guide bolt 37 to move a certain distance in the axial direction, a stop device 4 is provided at the inner end of the guide bolt.
6 is provided. Bearing 45 functions as a stop member.

These bearings carry guide bolts 37, and the inner end faces 55 of the bearings 45 form a stop for a stop device 46. The hinge flange 38 has a hole 48 and is inserted into a cutout 47 in the casing cover or stator 8 . Since the hole 48 is also provided with the hole 49 of the stator 8, the three hinge bolts are connected to both holes 48.
It can be inserted from 19. A further internal cutout 50 is provided in the casing cover or stator 8 to facilitate this insertion. Therefore, there is also a place here for the head 56 of the hinge bolt 39.

The casing 2 is opened by removing the casing cover or stator 8 as follows.

First, remove the fixing screw 23. Stator 8 , which is still in housing recess 52 due to hinge 51 , moves away from housing 2 in the direction of arrow B and is pulled out of housing recess 52 until stop device 46 abuts inner end face 55 of bearing 45 . The casing cover or stator 8 is then separated from the casing 2 and easily attached to the shaft 57 of the hinge bolt 39.
It can be rotated around. Finally, they are put back together in exactly the opposite order.

FIGS. 7 and 8 show examples of the construction of tools according to the present invention. The tool essentially consists of graduated rings 11 and 12 of the stator 8 or rotor 3, which are cut or cast into the tool chamber. Each ring has recesses 60 and 61
, and opposing rings are inserted into these recesses.

Both the stator 8 and the rotor 3 have theoretical conical surfaces 66 and 72 formed by their tools, and four parts 6 are formed on these conical surfaces.
0 and 61, the rings 11 and 12 are assembled in the tool chamber 71 and engaged. In that case, gaps 6a and 65 are formed between the bottom surfaces 58 and 59 and the top surfaces 63 and 62. These gaps 64 and 65 are parallel and slope from the inside to the outside in the usual way, so that a portion of the material is left largely undisturbed on its way from the inlet to the outlet and is not machined by the tool. flows through the gaps. Flow of the treatment material occurs in the direction of arrow C.

In this invention, the gap 64 is the bottom surface 5 of the stator ring 11.
8 and the head surface 63 of the stator ring 12, being shifted from the inside to the outside. Gap 65 between the bottom surface 59 of the rotor ring 12 and the top surface 62 of the stator ring 11
The same applies to The treated material is forcibly bent from ring stage to ring stage along the resulting baffle plate. The gaps 64 and 65 form a right angle and/or an acute angle with the 4° axis of the shaft 4 according to the invention. FIG. 7 shows an alternative configuration. That is, the gap 64 forms an acute angle to the axis 4'. In contrast, the gap 65 is at right angles. A combination of acute angles and right angles is also possible.

What is important is that the gaps 64 and 65 are not in line or in a straight line from the inside to the outside, respectively, but are offset from each other.

The staggered arrangement can be achieved as follows.

That is, starting from the virtual theoretical conical surface 66 of the rotor ring 12, the head surface 63a of the ring 12c or 12b etc.
Alternatively, G3b becomes thicker from the outermost ring 12d (not shown) toward the axis 4'' (dimension 67
Or, it is shifted by 68, thus forming a stepped shape. The recesses 1M≦60 of the rotor ring 12, which respectively face the stator ring 11, must have a correspondingly large offset. The bottom surface 59 of the rotor ring and the head surface 62 of the stator ring 11
The same can be said about the gap 65 between.

The individual rings 11 and 12 are provided with additional notches, thus forming individual teeth. With this invention,
The roots 69 and 70 of the individual tooth gaps of each ring are concave. This procedure allows the teeth to be manufactured advantageously using a simple side milling cutter.

FIG. 9 illustrates various combinations of features of the invention. The inlet 5 has a heat exchanger 74 in its area and in its upper half has a tube piece 7 and a flange 78 according to the state of the art, and a tube piece 81 forming a heat exchange surface is located on one side of the heat exchanger 74. It protrudes into the inlet pipe piece 7. In this case the outermost stator ring 11 with respect to the embodiment of FIG.
A fixing screw 19a of d passes through the stator 8a forming the casing cover from the outside.

In the lower half, the inlet 5 according to the invention is formed by a block flange which together with the stator S forms a unit, so that the construction of the machine is very advantageously compact.

The embodiment of FIG. 9 shows a rotor 3a fixed separately with a ring 82 used for tightening the outermost stator ring 11d by the use of a sunken screw 19 and an additional guide ring with a guide surface not shown. The fixing part of the innermost rotor ring L2a by the screw 83 from the back side is shown.

In this lower part, an example of a heat exchanger 74 having heat exchange surfaces on both sides is shown.

Figure 1O shows the installation of the heat exchanger. This heat exchanger has an exchange chamber 75, a guide lower part, an exchange medium take-out lower part 7, and a tube piece-like part 8 which forms a heat exchange surface. The tubing is in this case on one side and extends into the inlet tubing 7 and is shown enlarged between the flange 78 of the machine and the flange of the feed tube 73.
