The invention relates to a mixing device consisting of a upright, approximately cylindrical housing forming a mixing chamber with a laterally connected inlet pipe for a powdery solid and with at least one spray tube guided through the housing wall into the mixing chamber for a liquid, with a coaxially running, arranged with one or more fly knives or the like. Occupied mixer shaft and coupled to a drive member is. ·

Such mixing devices are, for example, continuous. Thoroughly mixing a powdery pesticide such as plaster of paris or cement with water or for granulating powdery substances Products, for example Thomas slag powder, are used by mixing them with a liquid.

In these known mixing devices, depending on the type of the products to be mixed, the finished mixture becomes so stiff that it is no longer due to gravity from the \ Mixing chamber slips out, causing V-clogging of the mixing chamber can occur. In addition, less stiff mixtures can be more or less strongly on the wall of the mixing chamber stick, which affects the mixing effect.

The invention has therefore set itself the task of a mixing device of the type mentioned in such a way that the aforementioned disadvantages are properly eliminated.

For this purpose, a mixing device according to the invention is essentially characterized in that the housing means lower and / or upper vibration dampers freely oscillating is stored and can be made to vibrate via a vibrator is, while the drive element and thus the one connected to it Mixer shaft with a fixed, rigid and vibration-free Support plate is connected and an elastically deformable sealing ring between the support plate and the upper edge of the housing, preferably a bellows is arranged, and that the inlet pipe for the solid is elastically deformable Ring, preferably a bellows, is sealingly connected to the rigid feed line and each spray tube is connected to an elastic feed hose. ,

As a result of the vibrations achieved by the vibrator, surprisingly the flow properties of the mixture are greatly improved so that the mixing chamber is not clogged at all can only occur. In addition, as a result of these vibrations, cleaning of the mixing chamber wall is very simple achieved, as any deposits on this wall are immediately shaken loose again.

Since the drive member and the mixer shaft with the fly knives or the like. Can not participate in the vibrations also no vibration stresses are transmitted to the drive element and the bearing of the mixer shaft. To this In this way, a mixing device with extremely high operational reliability is obtained.

As is usually the case with the discharge line for the finished mixture as the feed line for the pesticide consists of a fixed rigid pipe, this is also useful the outlet end of the housing located below is sealed by means of an elastically "deformable ring, preferably a bellows connected to the connecting piece of this rigid drain pipe.

A more detailed explanation of the invention emerges from the following description of a preferred exemplary embodiment based on the accompanying drawing, which shows the exemplary embodiment in a side view.

The illustrated mixing device according to the invention has a perpendicular, approximately cylindrical housing 1, which

a mixing chamber 2 forms. In this mixing chamber 2, a mixer shaft 3 runs coaxially to it, one or more of which Flying knife assemblies 4 carries and with a drive motor is coupled. This drive motor 5 is fixed to a stationary one rigid support plate 6 connected, which rests on supports 7 anchored in the ground.

The housing 1 is, however, resiliently mounted by it once is suspended from vibration dampers 8, which are attached to the support plate 6 and to the upper edge of the housing, while also resting on the foundation plate 9 further vibration damper 8 are provided, which on an annular attack flange 10 connected to housing 1.

On the outside of the housing 1 is a stiffening rail 11 extending approximately over the entire length of the housing, for example a U-profile, which carries a vibrator 12. Between the top of the housing 1 and the bottom of the Support plate 6 is an elastically deformable ring IJ, which in the illustrated embodiment from a plastic bellows consists, sealingly attached.

The housing 1 has an inlet pipe connected to the side 14 for feeding a powdery solid into the mixing chamber 2, This inlet pipe 14 carries an elastically deformable Ring 15, which in the illustrated embodiment consists of a plastic bellows and sealingly to a rigid feed line (not shown) for the powder material connected" "

In addition, a number of spray tubes 16 protrude through the wall of the housing 1 into the mixing chamber 2, which for serve to feed liquid into the mixing chamber and each to an elastic feed hose, not shown are connected. . .

The housing 1 protrudes with its lower outlet end with ample play through the foundation plate 9 downwards. Under the outlet opening of the housing, a storage container (not shown) can be arranged to collect the finished mixture, however can alternatively, as is provided in the illustrated embodiment, the lower outlet end of the Housing also has an elastically deformable ring 17 * which in the illustrated embodiment consists of a plastic bellows, sealing against a non-illustrated one rigid drain pipe connected.

In the embodiment shown in the figure, the drive motor 5 has a length that is only indicated schematically Bearing sleeve 18 to accommodate the bearings for the mixer shaft 3 »

During operation, the housing 1 of the mixing device is caused to vibrate via the vibrator 12, whereby the flow properties th of the mixture can be considerably improved and also sticking to the wall of the housing 1 and on the spray pipes 16 is prevented. The drive motor 5 and the mixer shaft 3 and the fly knife assemblies attached to it 4 do not take part in this oscillation movement, so that neither the drive motor 5 nor the bearings of the mixer shaft j5 are stressed by the vibrations.

Of course, the invention is not limited to that in the Figure limited embodiment shown, but can be modified in various ways.
