038), the venting air sucked in axially by the central air conduit is similarly (radially outwardly and axially sucked in) intimately mixing with the liquid sucked axially by the single rotor. 2 placed at a distance from each other
It is conveyed into a stator consisting of two disks and a vertical guide wall inserted between the disks. A vertical guide wall (a two-part flow path with a right-angled cross section)
By inducing a proper outflow into the liquid to be vented, it is possible to achieve a uniform venting of the liquid within a certain area around the stator. However, ventilation becomes weaker as the distance from the stator's outer circumference increases. This is because the flow velocity of the liquid-air mixture is reduced. This stiffness is necessary to ensure uniform aeration of the liquid over the entire cross section of the vessel given the rotor efficiency.
This means that the diameter of the container containing the liquid to be vented must not exceed a certain dimension.

できるように改善することである。Problem to be Solved by the Invention The problem underlying the invention is therefore to provide an aeration device of the above-mentioned type with a simple means of achieving uniform aeration even over a large container cross-section given the rotor efficiency. The goal is to improve so that it can be achieved.

流動路の隣接する垂直の仕切り面が固定子の外周に向っ

決する。Means for Solving the Problem The invention solves the problem set in that adjacent vertical partition surfaces of flow channels arranged directly next to each other diverge towards the outer periphery of the stator, in which case each flow channel The vertical partition surface is up to 7
This is solved by extending parallel to each other with a bias of .

通気を確保することができる。By such means, the vertical partition surfaces of the individual flow channels run at least approximately parallel to each other, so that the outflow velocity of the liquid-air mixture from the flow channels can be easily guided without the need for increasing the rotor efficiency. Compared to conventional stators with walls, this can be significantly increased. The high outflow velocity of the liquid-air mixture allows a correspondingly large outflow distance of the liquid-air mixture, thus ensuring uniform ventilation even in large vessel cross-sections. can be ensured.

とを考ヂしなければならない。Particularly advantageous structural relationships result here. This is because the size and shaping of the rotor determines the air and liquid ejected volume and thus the desired air permeability, and the structure of the stator flow passages has an important influence on the distance traveled by the ejected liquid-air mixture. This is because it has. The flow rate of the liquid-air mixture ejected from the stator can be adjusted by shaping the flow channels. If the vertical partition surfaces of the individual flow channels diverge towards the outer circumference of the stator, the outflow velocity of the liquid-air mixture can be correspondingly reduced compared to the inflow velocity into the stator. If the outflow velocity has to be increased, the vertical partition surfaces converge towards the outer circumference of the stator (secondarily, the flow cross-section of the flow channel can be reduced towards the outflow end. The angle between the vertical partition planes of the road is
Should not exceed 7 if an increase in vortex formation is not to be accepted. In this connection, it must therefore be taken into account that turbulence significantly limits the possible range of the ejected liquid-air mixture.

きである。As the diameter of the container increases, in order to ensure uniform ventilation of the container liquid even within the circumferential wall of the container, it is necessary to Care should be taken not to make the distance between streams too large. Therefore, even if the diameter of the container is large, consideration should be given to the corresponding number of flow channels in order to avoid exceeding the maximum permissible flow distance of adjacent flow channels.

中間部分に自由に接近しつるからである。The flow path may be configured in various ways. For example, it is also possible to form the flow channel by providing the web plate between two disks arranged at an axial distance from each other. However, a particularly advantageous construction results if the flow channel consists of a U-shaped profile placed on a disc. This design not only offers advantageous manufacturing conditions with relatively low material costs, but also allows easy cleaning of the stator. The reason for this is that there is free access to the intermediate part between the several U-forming profiles forming the flow path.

へ搬送する。According to the embodiment according to FIG. 1, the illustrated venting device arranged directly above the container bottom 1 mainly consists of a rotor 2 driven by a motor 3 and a stationary calf surrounding the rotor 2. Consisting of In this case, the vertical rotor 5 passes through the container bottom 1, on which the motor 3 is mounted with a flange. The air to be introduced into the liquid in the container is sucked in by a conduit 6 and fed axially to the rotor 2, which simultaneously sucks the liquid out of the container by means of the interannual lower of the stationary calf, as indicated by the flow arrows. The air is transported into the stator along with the air.

の通気が保証される。The liquid-air mixture in the fixed calf is introduced between two discs 10 and 11 according to FIGS. 1 to 3. It is accommodated in a flow channel 8 formed by vertical webs 9. The arrangement is such that the adjacent webs 9 of the flow channels 8, which are arranged directly next to each other, extend towards the outer circumference of the fixed calf, so that the vertical partition surfaces of the flow channels 8 are mutually (-
Parallel: two are made to extend. This structure causes an exit velocity of the flow from the flow channel 8 to approximately correspond to the inlet velocity of the liquid-air mixture conveyed by the rotor 2 into the stator hand, so that due to the relatively high exit velocity the flow Continuing into the container via a large radius. At the same time, a vessel with a large channel diameter and a corresponding number of flow channels ensures uniform ventilation if care is taken that the flow in adjacent flow channels does not diverge too strongly, especially in the area of the circumferential wall of the vessel. is guaranteed.

の間の楔状部分は自由に接近しうるからである。As FIG. 4 shows, a particularly simple stator construction is obtained by forming the flow channel 8 by a U-shaped profile 12 resting on a disk 13. As shown in FIG. This construction not only ensures easy manufacture, but also offers advantages in terms of stator cleanliness. This is because the wedge-shaped sections between adjacent flow channels are freely accessible.

程を著しく制限するからである。In order to be able to determine the exit velocity of the liquid-air mixture from the stator given the rotor efficiency required for venting a liquid container with a constant diameter, individual flow channels are The vertical partition planes of 8 can be offset from their parallel extension. For example, if the webs 9 of the individual flow channels δ are arranged so as to diverge towards the outer circumference of the stator 4, a deceleration of the flow in the flow channels 8 occurs. In this case, the angle α between the vertical webs 9 must not exceed 7. This is because otherwise an increase in vortex formation would have to be taken into account, which would significantly limit the range of the flow exiting the flow channel 8.

It is also possible to suck in not only on one side of the rotor (as shown in the figure), but also on both sides of the rotor. The structure of the rotor can also be designed in such a way that air can be drawn in from below the rotor and the motor can be mounted above the rotor in the form of a known embodiment of an immersion motor in a container. Of course, it inhales any gas other than air and any one of the specified liquids.
It can also be distributed to. In this case, depending on the structure of the rotor, the inclination of the flow channels 8 relative to the radial direction can be determined, the number of flow channels being selected depending on the inclination of the flow channels and the diameter of the container. Wear. Furthermore, the bottom surfaces of the adjacent webs 9 of the flow channels 8 arranged side by side have a wedge-shaped shape in order to ensure that the vertical partition surfaces of the respective flow channels run at least approximately parallel. They can be formed using common intermediates.
