Definitions
- the present invention relates to an apparatus for dispersing a substance in a liquid.
- Such devices serve to form a dispersion by finely distributing the substance in a liquid.
- the substance may be in solid, liquid or gaseous phase or else as a mixture of different phases.
- the problem with the mixing process is often the wetting and the homogeneous distribution of the substance. If this is powdery, there is also the danger that unwanted dust from unwetted powder forms in the environment.
- Liquid flow rate and the pressure at the outlet depends, so that it may be too low to suck the substance to be dispersed in sufficient mass and wet.
- US-A-3, 119, 339 and US-A-3, 932, 302 disclose devices for generating a dispersion of gas and liquid. These include an eccentrically arranged gear with internal teeth which engage in a pinion and a crescent-shaped insert. Such devices have u. a. the disadvantage that they are unsuitable for dispersing powdery substances. Since these are almost incompressible, so large forces would be generated when meshing the internal teeth in the pinion that the device z. B. would damage the walls of the teeth or pinion or possibly the bearings. Another disadvantage is that the throughput and thus the volume of dispersion that can be generated per unit time are relatively low.
- an object of the present invention is a device specify which allows it in a simplified and improved way to suck in substance and to distribute as homogeneously as possible in a liquid.
- Fig. 1 is a partially sectioned side view of the device according to the invention.
- Fig. 2 shows the device according to FIG. 1 in the section plane H-II;
- Fig. 3 shows the device according to FIG. 1 in the sectional plane HI-III;
- Fig. 4 is a hydraulic diagram of the device according to the invention.
- Fig. 5 shows a further variant of a hydraulic scheme of the device according to the invention.
- Fig. 6 is a partially sectioned side view of another embodiment of the device according to the invention.
- Fig. 7 is a hydraulic diagram of the device according to FIG. 6;
- Fig. 8 shows a further variant of a hydraulic scheme of the device according to FIG. 6
- Fig. 9 shows a side view of a further embodiment of the driving means for the device according to the invention
- FIG. 10 is a perspective view of the driving means according to FIG. 9.
- Fig. 11 shows a further variant of the openings 30 ", 35 'and 40' of the device according to FIG. 1 in the sectional plane H-II.
- the dispersing device comprises a dispersing chamber 10, which is preferably delimited laterally by a cylindrical wall 11.
- the dispersing chamber 10 contains a driving means 12, by means of which liquid is set in motion.
- the driving means is preferably designed as an impeller 12.
- This comprises a hub 13 which is rotatable about the axis of rotation 16 and on which a plurality of wings 14 are mounted.
- the impeller 12 is arranged eccentrically in the dispersing chamber 10, so that the axis of rotation 16 is adjacent to the center 18 of the dispersing chamber 10.
- the impeller 12 is fixed to a shaft 19, which is by means of drive (not shown) in rotation displaceable.
- the shaft 19 is arranged vertically. It is also possible to orient the disperser in a different position, for example, so that the shaft 19 is arranged horizontally.
- the dispersing chamber 10 is provided at the top with a cover 29, which contains a substance inlet 30 for introducing material into the dispersing chamber 10 and an outlet 35 for discharging the product from the dispersing chamber 10.
- Inlet inlet 30 and outlet 35 are each connected to a supply line 31 and 36, respectively. If, as mentioned above, the shaft 19 is aligned horizontally, it is advantageous to arrange the material inlet 30 at a higher level than the outlet 35.
- the shape of the material inlet 30 and the outlet 35 is substantially sickle-shaped, so that the distance between the edges 32 and 33 of the material inlet 30 in the direction of rotation 17 increases and the distance between the edges 37 and 38 of the outlet 35 decreases in the direction of rotation 17 ,
- the inner edge 32 of the material inlet 30 and the inner edge 37 of the outlet 35 are approximately on a circle whose center lies on the axis of rotation 16 of the impeller 12.
- the outer edge 38 of the outlet 35 lies on a circle 39 which is substantially concentric with the wall 11 of the dispersion chamber 10.
- Cloth inlet 30 is also substantially circular in shape and arranged so that it lies within the circle 39. This arrangement counteracts the risk that, during operation, liquid from the dispersion chamber 10 can penetrate into the substance inlet 30 and the supplied substance is able to agglomerate.
- the shape of the supply line 31 to the material inlet 30 is cylindrical, then - if necessary - the transition of the supply line 31 in the sickle shape of the material inlet 30 so be optimized that even at high turbulence no liquid from the dispersion chamber 10 can inject into the material inlet 30.
- the transition to this is not abrupt in cross section, but for example, ramp-shaped, so seen in the direction of flow, the central part of the material inlet is higher than its two ends.
- the dispersing chamber 10 below contains a disk 41 with a liquid inlet 40 for introducing liquid into the dispersing chamber 10.
- the liquid inlet 40 is arranged substantially between the material inlet 30 and the outlet 35, wherein viewed in the direction of rotation 17, the material inlet 30 are arranged in front of the liquid inlet 40 and that in front of the outlet 35.
- the liquid inlet 40 has in the example according to FIG. 2 is a substantially circular shape.
- FIG. 1 shows the position of the liquid inlet 40 with respect to that in FIG. 2- position shown rotated by 90 degrees.
- the disc 41 is rotatably arranged so that the position of the liquid inlet 40 with respect to the neutral axis, which passes through the points 16 and 18, is variable.
- the dispersing device further comprises pumping means 61 for passing liquid through the
- the dispersing device shown so far works as follows:
- the impeller 12 is in the in Fig. 2 indicated direction 17 in rotation and pumped liquid by means of the pumping means 61 through the liquid inlet 40 into the dispersion chamber io.
- the liquid is also set in rotation and driven outwards due to the centrifugal force, so that it stands out from the hub 13 and a circumferential liquid ring 47 is formed which is substantially concentric with the wall II of the dispersing chamber 10.
- the transition between the ring 47 with circulating liquid and the liquid-reduced inner region is indicated by a dot-dash line 39.
- the position of this transition 39, and thus the thickness of the liquid ring 47 is essentially given by the position of the outer edge 38 of the outlet 35, because, as explained below, due to the pumping action, liquid located in the interior is conveyed through the outlet 35 ,
- a cavity 50-57 Between the base 15 of adjacent blades 14 and the liquid ring 47 is formed in each case a cavity 50-57, the volume of which is repeatedly increased and decreased by the rotation of the impeller 12, whereby a pumping action is generated. If z. B. from the in Fig. 2, provided with the reference numeral 50, the cavity initially increases in volume as it moves toward the position of the cavity 51. By this increase in volume, a negative pressure is generated, which causes substance through the fabric inlet 30 in the
- Dispergierhunt 10 is sucked in and finally wetted with the liquid and mixed.
- the generated suction effect ensures that the substance does not already come into contact with liquid in the material inlet 30 and that the substance inlet 30 is clogged due to the formation of lumps.
- the cavity 50 then passes through the area of the in Fig. 2 with the reference numerals 52 and 53 designated cavities, where their volume barely changes, so that neither a suction nor pumping action is generated. In this neutral Zone, the liquid inlet 40 is arranged. Thereafter, the cavity 50 moves in the direction of the position of the cavity 54, so that its volume decreases again and the product consisting of liquid and substance contained therein is expelled through the outlet 35. As a result, the cavity 50 in the region of the cavities 55 and 56 again passes through a neutral zone between the pressure and suction sides.
- the dispersing chamber 10 is designed so that the
- Flow conditions are usually turbulent and a fine distribution of the substance in the liquid is favored.
- the mixing ratio of substance and liquid can be adjusted.
- the position of the liquid inlet 40 is displaced either more in the direction of the pressure side or more in the direction of the suction side, so that the amount of liquid is regulated in accordance with which per unit time in the
- Dispersing chamber 10 flows.
- the dispersing chamber 10 Due to the rotation of the driving means 12, intensive wetting of the substance in the dispersing chamber 10 takes place. As a result, the risk of lump formation is virtually eliminated, especially in the case of powdery substances. This is also effectively avoided by allowing the dispersing chamber 10 to be designed to be free of narrow gaps or other narrow spaces.
- the wings 14 need not be disposed radially displaceable, but may be fixedly connected to the hub 13.
- a high vacuum is generated with high suction power at the same time, and this is essentially independent of the fluid flow rate and, to a certain extent, also regardless of the pressure at the outlet 35. As a result, dust-free incorporation into the liquid is ensured, in particular in the case of pulverulent substances. It has been shown that the producible suction power is sufficient to heavy powder, z. B. metal-containing powder to be able to suck.
- the cavities are liquid-reduced areas, which u. a. are delimited by the fluid itself (cf the dash-dotted line 39 in Fig. 2). There are therefore no problems with the seal or lubrication, as they occur for example in the known dispersing, in which engages a gear in a pinion to produce a variable working volume.
- the dispersing device has a liquid inlet 40, so that the liquid in the ring is continuously exchanged during operation.
- Water-ring pumps contain water as the working liquid, which permanently remains in the working chamber.
- the outlet 35 is fluidically connected to the liquid inlet 40. This allows the liquid to be passed through the dispersing chamber 10 several times.
- the substance inlet 30 is advantageously z. B. closed by a valve and the dispersion passed through the dispersion chamber 10 several times.
- a second dispersing chamber 60 is provided in a second continuation of the dispersing device, which is likewise shown in FIG. 1, a second dispersing chamber 60 is provided. This is fluidically connected to the first dispersion chamber 10 via the liquid inlet 40 and is located according to FIG. 1 below this.
- the second dispersing chamber 60 at least one dispersing tool 61 is arranged, which serves as a pumping means and as a processing means to distribute the substance in the liquid very finely.
- the dispersing tool 61 comprises rotor 62 and stator 63, wherein the rotor 62 is advantageously mounted on the same shaft 19 as the impeller 12. This allows the same drive to be used to set the impeller 12 and the dispersing tool 61 in motion.
- Fig. 3 shows an example of a dispersing tool 61 having two sprockets 62a and 62b forming the rotor 62 and two sprockets 63a and 63b constituting the stator 63.
- the sprockets 62a, 62b, 63a, 63b have slots 64 through which liquid and material contained therein can pass.
- the dispersing tool 61 is provided in the inner region with a passage 69 which is fluidically connected to a supply chamber 70. This supply chamber 70 is shown in FIG. 1 below the dispersing tool
- the senor 61 and includes an inlet 71. If the dispersion is to be recirculated, then the outlet 35 of the first dispersion chamber 10 is connected to the inlet 71.
- liquid is first sucked in from the supply chamber 70 by means of the dispersing tool 61 and pumped via the liquid inlet 40 into the first dispersing chamber 10, where, as already explained above, a liquid ring is formed. Cloth is drawn in through the fabric inlet 30 and dispersed in the liquid. The resulting dispersion is passed via the outlet 35 and the inlet 71 back into the feed chamber 70.
- the liquid and the substance contained therein are processed accordingly as they pass through the slots 64 of the rotor 62 and stator 63, resulting in a more refined and homogenized distribution of the substance.
- the liquid circulates several times between the first and second dispersing chambers 10 and 60 until the desired substance concentration and / or until a sufficiently homogeneous dispersion is achieved.
- the provision of two dispersion chambers 10 and 60 has the advantage that the wetting of the substance with liquid and the processing with the dispersing tool 61 take place in separate chambers and thus do not mutually influence the two processes. This makes it possible to produce particularly homogeneous dispersions without problems with lump formation and / or with undesirable dust formation in the case of pulverulent substances.
- Fig. 4 shows a third continuation of the dispersing device in schematic form.
- Rectangle 80 is a schematic representation of the dispersing unit containing the first dispersing chamber 10 and the driving means 12 and, if provided, the second dispersing chamber 60 and the dispersing tool 61.

- Supply line 88 which is connected to the inlet 81, serves to supply the liquid.
- Discharge line 89 which opens into the recirculation line 85, serves to remove the dispersion made of liquid and fabric.
- the lines 84, 88 and 89 are provided in known manner with valves 90, 91 and 92, respectively, in order to open and block the respective passage.
- Liquid which leaves the outlet 35, in addition to the substance also ambient air, so it can be deposited in the separation vessel 86 and a safe operation of the dispersing tool 61 can be ensured.
- the dispersing device is also possible to form a closed system, so that gas exchange with the environment is prevented.
- the feed tank 83 and the separation tank 86 are formed closed in this case.
- the use of a closed system is advantageous, for example, if the substance to be dispersed is a very fine powder and unwanted powder deposits in the environment are to be avoided. If the powder is difficult to disperse and / or very fine, it may be that undispersed powder is still present in the air, which is in the separation tank 86. This can be returned via the return line 87 to the feed container.
- FIG. 5 shows a variant of the dispersing device for batch operation, wherein in FIGS. 4 and 5 identical parts are given the same reference numerals.
- the rectangle with the reference numeral 82 represents schematically a container in which the liquid is received. If no deposition of gas and / or non-dispersed matter is required, the separation vessel 86 may also be omitted.
- the container is connected to the inlet 81 via the line 88 'and to the outlet 35 via the lines 89' and 85 '.
- the liquid is passed several times through the dispersion unit 80, in which the substance from the feed tank 83 is added, and passed through the container 82 until the desired substance concentration and homogeneity is achieved.
- the dispersion thus prepared is finally collected in the container 82 and this separated from the dispersion 80. It can be made in a simple manner certain batches of dispersions.
