Description of design examples

In the examples of constructive implementation described below, various structural units and/or structural elements are presented repeatedly. Similarly made structural elements and/or structural units, which are provided with the same reference symbols in the drawings, for simplicity, are described only once in the following description of the drawings.

Figure 1 shows part of the mixing plant 34a. The mixing plant 34a includes a mixing plant device 10a. The mixing device 10a is designed to mix one fluid with another fluid. The mixing device 10a is designed to disperse one fluid into another fluid. One fluid is a gaseous phase. Another fluid in the initial state is a liquid phase. In operating mode, the other fluid is a mixed phase of gas and liquid.

The mixing device 10a includes a mixing shaft 38a. The mixing shaft 38a rotates in at least one operating mode around the axis of rotation 12a of the mixing device 10a. The impeller shaft 38a transmits torque and sets the elements arranged on the impeller shaft 38a into rotational motion. The mixing shaft 38a is driven by the motor 46a of the mixing unit 34a.

The impeller shaft 38a is designed as a hollow shaft. The rotation axis 12a extends inside the mixing shaft 38a. The impeller shaft 38a is aligned parallel to the vertical. The impeller shaft 38a has a plurality of inlets 44a. The inlet holes 44a are provided in order to suck in the fluid in operation.

The mixing device 10a includes a fluid dispersion unit 14a. The impeller shaft 38a is connected in a hydrodynamic manner to the fluid dispersion unit 14a. The fluid dispersion unit 14a is located on the impeller shaft 38a without being able to rotate. The fluid dispersion unit 14a is positioned on the impeller shaft 38a by means of a positive and/or positive connection. The connection is a screw connection. The fluid dispersion unit 14a is rotatable about an axis 12a of rotation. The impeller shaft 38a and the fluid dispersion unit 14a rotate in operation at the same angular velocity. In operation, the fluid dispersion unit 14a is completely immersed in another fluid.

The fluid dispersion unit 14a has an outlet 16a. The outlet 16a in the direction of the sight line perpendicular to the main strike plane 68a of the outlet 16a has a rectangular shape. Alternatively, the outlet 16a in the direction of the sight line perpendicular to the main strike plane 68a of the outlet 16a could have an oval or round shape.

The fluid dispersion unit 14a has another outlet 22a. Another outlet 22a, when viewed in the direction of rotation 36a of the fluid dispersion unit 14a, is located in front of the outlet 16a.

The fluid dispersion unit 14a has four outlets 16a, 22a. Outlets 16a, 22a are respectively provided for one fluid outlet. The fluid dispersion unit 14a includes four dispersion blades 40a. Each of the four dispersing blades 40a respectively defines one of the outlets 16a, 22a. The dispersing blades 40a are suitably designed as a mixing paddle.

In the operating mode, the outlet openings 16a, 22a, when the fluid dispersion unit 14a is rotated in the rotation direction 36a, are oriented in the direction opposite to the rotation direction 36a.

The outlet openings 16a, 22a are located relative to each other at the same angular distance, respectively, in the circumferential direction of the fluid dispersion unit 14a.

In the following, only one of the four dispersing vanes 40a and only one of the four outlets 16a, 22a will be described, the description being to be considered valid for all of the dispersing vanes 40a and all of the outlets 16a, 22a.

The dispersing blade 40a is curved in the plane of rotation of the fluid dispersion unit 14a. The dispersing blade 40a extends radially outward from the nearest to the midpoint portion of the fluid dispersion unit 14a. The dispersing blade 40a is hollow. The dispersing blade 40a is in hydrodynamically communicating connection with the metal shaft 38a. The dispersing vane 40a defines a fluid channel 42a with an outlet 16a.

In a cross-sectional plane 70a extending at least substantially transverse to the direction of the internal fluid flow 54a through the fluid channel 42a, the outer restriction element 72a of the dispersing vane 40a has a rectangular shape. Alternatively, the outer limiting member 72a of the dispersing vane 40a in a sectional plane 70a extending at least substantially transverse to the direction of the internal fluid flow 54a through the fluid channel 42a could be oval or circular in shape.

The shape of the outlet 16a in the direction of the sight line perpendicular to the main plane of strike 68a of the outlet 16a and the shape of the element 72a of the outer limit of the dispersing vane 40a in the plane 70a of the section passing at least essentially transverse to the direction of the internal flow 54a of the fluid through the channel 42a of the fluid , are essentially the same. It is possible that the shape of the outlet 16a in the direction of the sight line is perpendicular to the main plane of strike 68a of the outlet 16a and the shape of the element 72a of the outer limit of the dispersing vane 40a in the plane 70a of the section passing at least substantially transverse to the direction of the internal flow 54a of the fluid through the fluid channel 42a are different from each other.

Sectional plane 70a and main extension plane 68a of outlet are claimed to be at least substantially congruent in the region of outlet 16a.

The mixing device 10a includes an optimization unit 18a. The fluid dispersion unit 14a and the optimization unit 18a are defined in part in a monoblock design. The optimizing unit 18a in operation increases the differential pressure at the outlet 16a, 22a.

Optimization block 18a includes contour block 66a. The contour block 66a is located on the mixing shaft 38a. Contour block 66a is provided to facilitate entry of fluid into inlets 44a. The contour block 66a includes a contour element 62a. The contour block 66a includes several contour elements 62a.

The contour element 62a is designed as a guide plate 64a. The contour element 62a is set to be curved in shape. The contour element 62a is located directly on the inlet 44a. Each contour element 62a is associated specifically with one inlet 44a. The contour element 62a directs the fluid towards the inlet 44a associated with the contour element 62a. Contour elements 62a are associated respectively with each inlet 44a.

The optimization unit 18a includes an external pressure optimization unit 20a. The external pressure optimization unit 20a lowers the external pressure downstream of the outlet 16a, 22a in operation.

The fluid dispersion unit 14a and the external pressure optimization unit 20a are defined partially in one-piece execution with each other.

The external pressure optimization unit 20a includes a paddle wheel 48a. A propeller blade 24a is mounted on the paddle wheel 48a. Another propeller blade 60a is mounted on the paddle wheel 48a. Four propeller blades 24a, 60a are mounted on the paddle wheel 48a. The propeller blades 24a, 60a are rotatable about an axis 12a of rotation. Propeller blades 24a, 60a are located relative to each other, respectively, at the same angular distance in the circumferential direction of the blade wheel 48a. Propeller blades 24a, 60a are provided to create an external fluid flow 50a. The number of propeller blades 24a, 60a corresponds to the number of outlets 16a, 22a.

The paddle wheel 48a is located below the fluid dispersion unit 14a. Propeller blades 24a, 60a, when viewed along the axis of rotation, are offset downward relative to the outlet holes 16a, 22a. Each propeller blade 24a, 60a is associated specifically with one of the outlets 16a, 22a.

The external pressure optimization unit 20a in operation generates an external fluid flow 50a by means of the propeller blades 24a, 60a. The external flow 50a of the fluid in one section of the flow runs parallel to the axis of rotation 12a (see figure 1).

The external pressure optimization unit 20a includes a flow guide 26a. The flow guide 26a is positioned above the outlets 16a, 22a. The flow guide element 26a is designed as a closed disk. The flow guide element 26a is given in one-piece execution with the fluid dispersion unit 14a. The flow guide 26a is provided to deflect the external fluid flow 50a in a direction perpendicular to the rotation axis 12a of the fluid dispersion unit 14a.

The external pressure optimizing unit 20a lowers the external pressure preventing fluid from escaping during operation. The operating mode external pressure optimization unit 20a reduces the effect on the fluid outlet from the outlet 16a by another fluid outlet from another outlet 22a which, when viewed in the direction of rotation 36a, is located in front of the outlet 16a.

The outlet 16a and the other outlet 22a together define the dispersion cell 56a. Each outlet 16a, together with the outlet 16a immediately following it, defines its own dispersion cell 56a.

The following description is to be considered valid for all fluid outlets at the points of all four outlets 16a, and only the fluid outlet at one of the four outlets 16a is described here. As a result of the exit of the fluid at the outlet point 16a in the dispersing vane 40a, the dispersion cell 56a is swirled on the dispersing vane 40a following the dispersing vane 40a in the rotational direction 36a of the fluid dispersion unit 14a. The other fluid injected by the propeller blade 24a washes away (carries away) these turbulences. As a result, the other fluid increases within the dispersion cell 56a the average flux density at the dispersion vane 40a with a different outlet 22a.

The fluid dispersion unit 14a has four-cell symmetry. The dispersion cells 56a are arranged symmetrically around the fluid dispersion unit 14a. Each dispersion cell 56a, by rotating through 90° in the direction of rotation 36a, can be brought into a position of overlap with the dispersion cell 56a immediately following it. Each dispersion cell 56a can be rotated through 360° around the rotation axis 12a to its own position. The fluid dispersion unit 14a may have any n-cell symmetry, with n being the number of outlets 16a, 22a.

The fluid dispersion unit 14a has a receiving cavity 52a (see FIG. 3). The receiving cavity 52a is made in the form of a cylinder. The optimization block 18a includes an internal pressure optimization block 58a. The internal pressure optimizing unit 58a increases the internal pressure during operation. The internal pressure optimization unit 58a is located entirely within the fluid dispersion unit 14a.

The internal pressure optimization unit 58a includes a fluid injection unit 28a. The fluid injection unit 28a is in the form of a turbine. The fluid injection unit 28a is located entirely within the fluid dispersion unit 14a. The fluid injection unit 28a is located entirely within the receiving cavity 52a (see FIGS. 1-3).

The fluid injection unit 28a includes a plurality of guide vanes 32a. The number of outlet holes 16a, 22a corresponds to the number of guide vanes 32a. The fluid injection unit 28a includes four guide vanes 32a. The guide vanes 32a are given a correspondingly curved shape. The guide vanes 32a are located relative to each other at the same angular distance, respectively, in the circumferential direction of the fluid injection unit 28a.

The receiving cavity 52a and/or the transitional portion of the receiving cavity 52a to the fluid channel 42a is(are) provided with a smooth surface and/or without flaring. The fluid contacting surfaces of the fluid injection unit 28a are smooth and/or without flaring.

In operation, the motor 46a causes the mixing shaft 38a to rotate about the rotation axis 12a. Connected to the impeller shaft 38a without being able to rotate, the fluid dispersion unit 14a rotates in operation around the rotation axis 12a.

In the operating mode, a vacuum occurs at the outlets 16a, 22a. In operation, the fluid through the inlet holes 44a flows into the mixing shaft 38a. The mixing shaft 38a is connected to the receiving cavity 52a in a hydrodynamic manner. As a result of the differential pressure between the inlets 44a and the outlets 16a, 22a, an internal fluid flow 54a occurs. The internal fluid flow 54a passes from the inlets 44a first through the mixing shaft 38a and then through the fluid dispersion unit 14a to the outlets 16a, 22a.

In the operating mode, the fluid reaches the receiving cavity 52a. The guide vanes 32a of the fluid injection unit 28a inject the fluid in the region 30a proximal to the rotation axis parallel to the rotation axis 12a. The fluid injection unit 28a injects fluid from the region 30a of the fluid dispersion unit 14a proximal to the axis of rotation radially outward towards the outlet 16a.

The fluid injection unit 28a creates an optimized internal fluid flow 54a in operation. The fluid injection unit 28a creates an irrotational internal fluid flow 54a in operation. The fluid injection unit 28a in operation reduces pressure losses.

It is possible that the mixing device 10a mixes with each other and/or disperses three different fluids. In this case, the inlets 44a are in the first fluid with the lowest density, the external pressure optimization unit 20a is in the second fluid with the highest density, and the fluid dispersion unit 14a is in the third fluid with an average density, the value of which falls between the value for the lowest density and the value for the highest density. In addition, at least one of the three fluids can be mixed with at least one solid phase, such as a catalyst.

Figure 4 shows an alternative example of the design of the device 10b of the mixing plant. To prevent unnecessary repetition in this regard, the same reference designations are used for the same structural components and reference is made to the embodiments of FIGS. 1-3. In the following, only details are discussed in which the embodiment of FIGS. 1-3 differs from the alternative embodiment of FIG. 4. To distinguish between the examples of constructive implementation, after the reference symbols in an alternative example of a constructive implementation in figure 4, the letter "b" is placed.

Figure 4 shows a schematic perspective view of the fluid dispersion unit 14b of the alternative mixing unit 10b and the optimizer unit 18b of the alternative mixing unit 10b with the fluid injection unit 28b.

The fluid dispersion unit 14b has an outlet 16b. The outlet 16b in the direction of the sight line perpendicular to the main plane of strike 68b of the outlet 16b has a semicircular shape. Alternatively, the outlet 16b in the direction of the sight line perpendicular to the main plane of strike 68b of the outlet 16b could have an oval or round shape.

The fluid dispersion unit 14b has another outlet 22b. Another outlet 22b, when viewed in the direction of rotation 36b of the fluid dispersion unit 14b, is located in front of the outlet 16b.

The fluid dispersion unit 14b has four outlets 16b, 22b. Outlets 16b, 22b are respectively provided for one fluid outlet. The fluid dispersion unit 14b includes four dispersion blades 40b. Each of the four dispersing blades 40b respectively defines one of the outlets 16b, 22b. The dispersing blades 40b are respectively formed as a mixing paddle.

In operation, the outlet openings 16b, 22b are oriented in the direction opposite to the direction of rotation 36b when the fluid dispersion unit 14b is rotated in the direction of rotation 36b.

The outlet holes 16b, 22b are located relative to each other at the same angular distance, respectively, in the circumferential direction of the fluid dispersion unit 14b.

In the following, only one of the four dispersing vanes 40b and only one of the four outlets 16b, 22b will be described, the description being to be considered valid for all of the dispersing vanes 40b and all of the outlets 16a, 22b.

The dispersing blade 40b is curved in the plane of rotation of the fluid dispersion unit 14b. The dispersing vane 40b extends radially outward from the proximal to midpoint portion of the fluid dispersion unit 14b. The dispersing blade 40b is hollow. The dispersing blade 40b is in hydrodynamically communicable connection with the metal shaft 38b. The dispersing vane 40b defines a fluid channel 42b with an outlet 16b.

In a sectional plane 70b extending at least substantially transverse to the direction of the internal fluid flow 54b through the fluid channel 42b, the outer limit member 72b of the dispersing vane 40b has a semicircular shape.

The shape of the outlet 16b in the direction of the sight line perpendicular to the main plane of strike 68b of the outlet 16b and the shape of the element 72b of the outer limit of the dispersing vane 40b in the plane 70b of the section passing at least essentially transverse to the direction of the internal flow 54b of the fluid through the channel 42b of the fluid , are essentially the same. It is possible that the shape of the outlet 16b in the direction of the sight line is perpendicular to the main plane of strike 68b of the outlet 16b and the shape of the element 72b of the outer limit of the dispersing blade 40b in the plane 70b of the section passing at least substantially transverse to the direction of the internal flow 54b of the fluid through fluid channel 42b are different from each other.

Section plane 70b is oriented at least substantially parallel to the main strike plane 68b of outlet 16b.

FIG. 5 shows a schematic perspective view of the fluid dispersion unit 14c of the alternative agitator device 10c and the optimizer unit 18c of the alternative agitator device 10c with the fluid injection unit 28c.

To prevent unnecessary repetition in this regard, the same reference designations are used for the same structural components and reference is made to the embodiments of FIGS. 1-4. In the following, only details are discussed in which the embodiments of FIGS. 1-4 differ from another alternative embodiment of FIG. 5. To distinguish the examples of constructive implementation, after the reference symbols in another alternative example of a constructive implementation in figure 5, the letter "c" is placed.

The fluid dispersion unit 14c includes a turbulence unit 74c. Block 74 with turbulence is made in the form of a spiral. Turbulence block 74c includes helix 76c. It is possible that the turbulence unit 74 c includes several helices 76 c which, in at least one operating mode, are primarily wrapped around each other. It is conceivable that several helices 76 c are disposed one below the other. In addition, it is possible that the spiral 76 with, at least partially located on the rod block 14 with the dispersion of the fluid.

The turbulence unit 74c, when viewed along the axis of rotation 12c of the fluid dispersion unit 14c, is located in the outer region of the agitator device 10c. The turbulence block 74c is located between the dispersing vanes 40c.

The turbulence block 74c is provided to facilitate the transition from one fluid to another fluid. After exiting the fluid from the outlet 16c, the fluid at least partially bathes the turbulence block 74c. Block 74 with turbulence creates turbulence and/or shear forces in the area near block 74 with turbulence. Turbulences and/or shear forces distribute the fluid.

In the case where the fluid is in the gaseous phase, the turbulence unit 74 c reduces the diameter of the primary fluid gas bubbles emerging from the outlet 16 c and/or the other outlet 22 c. The turbulence block 74c breaks up the primary gas bubbles leaving the outlet 16c and/or another outlet 22c into several smaller gas bubbles.

Fig. 6 shows a schematic perspective view of the fluid dispersion unit 14d of the mixing unit 10d and the optimizer unit 18d of the mixing unit 10d with the fluid injection unit 28d.

To prevent unnecessary repetition in this connection, the same reference designations are used for the same structural components and reference is made to the embodiments of FIGS. 1-5. In the following, only details are discussed in which the embodiments of FIGS. 1-5 differ from the other alternative embodiment of FIG. 6. In order to distinguish the examples of constructive implementation, the letter "d" is placed after the reference symbols in an alternative example of a constructive implementation in Fig.6.

In contrast to the embodiments of FIGS. 1-5, the fluid dispersion unit 14d is set in a symmetrical design. The fluid dispersion unit 14d includes six circular 78d tubes that are arranged symmetrically around the circumference of the fluid dispersion unit 14d. Each of the circular tubes 78d defines one dispersion cell 56d. Each of the round tubes 78d can be moved by 60° in the direction of rotation 36d to overlap the immediately following round tube 78d. Each of the tubes of circular 78d cross-section as a result of turning through 360° around the axis of rotation 12d can be translated into its own position. Each of the circular tubes 78d has one fluid outlet 16d, 22d.

Figures 7 and 8 show, in two schematic axonometric views, a fluid dispersion unit 14e of a mixing apparatus 10e and an optimization unit 18e of a mixing apparatus 10e with a fluid injection unit 28e.

To prevent unnecessary repetition, the same reference designations are used for the same subassemblies and reference is made to the embodiments of FIGS. 1-6. Further in the text, only the details are considered, in which the examples of constructive implementation in Figs. 1-6 differ from the example of constructive implementation in Figs. 7 and 8. e".

The fluid dispersion unit 14e is set in a symmetrical design. The fluid dispersion unit 14e has six dispersion cells 56e which are arranged symmetrically around the fluid dispersion unit 14e. Each dispersion cell, as a result of turning through 60° in the direction of rotation 36e, can be brought into a superposition position on the immediately following dispersion cell 56e. Each dispersion cell 56e can be rotated through 360° about the axis of rotation 12e of the fluid dispersion unit 14e into its own position. Each of the dispersion cells 56e has one outlet 16e, 22e.

In the direction of the sight line, perpendicular to the rotation axis 12e, the fluid dispersion unit 14e has at least portions the shape of the bearing plane profile 80e. When looking at the dispersion cell 56e of the fluid dispersion unit 14e, the fluid dispersion unit 14e has a profile nose 82e facing in the direction of rotation 36e and a rear profile edge 84e farthest in the direction of rotation 36e. The profile toe 82e and the profile trailing edge 84e define the area of the fluid dispersion unit 14e with the bearing plane profile shape 80e. Starting from the toe 82e of the profile, the outlet 16e extends towards the trailing edge 84e of the profile and has a semi-oval cross section.

The propeller blade 24e has a curved shape in the direction of rotation 36e. Optimization unit 18e includes another propeller blade 86e. Another propeller blade 86e is associated with the outlet 22e. The other propeller blade 86e is located at a distance from the propeller blade 24e.
