DE8802260U1 - Mixing device for mixable goods - Google Patents

Description

The invention relates to a mixing device for mixable goods according to the preamble of claim 1.

Such mixing devices are already known, in which the mixing container is driven by a motor so that it is forced to rotate. This requires an additional motor with a gearbox and the corresponding switching devices. The cost of such a mixing device is therefore relatively high, as are the manufacturing costs and maintenance.

The object of the invention is therefore to simplify such a mixing device while maintaining the same high mixing effect.

This object is achieved by the invention by the features stated in the characterizing part of claim 1.

The advantages achieved with the invention are in particular that the mixing device is significantly simplified by the fact that the mixing container is simply mounted in a driveless, rotating manner. Not only are the corresponding units for driving the mixing container eliminated, but so are their maintenance and energy costs. Furthermore, the mixing effect can be adapted to the material to be mixed by adjusting the agitator radially. The mixing device according to the invention can therefore be used for different materials to be mixed and is also easy to handle.

Further features of the invention are the subject of the subclaims.

An embodiment of the invention is shown in the drawing and is explained below . Show it:

Fig. 1 shows the view of the mixing device; Fig. 2 shows the sectional view along line II - II in Fig. 1.

The mixing device for mixable goods, i.e. liquid or dough-like goods such as glue, mortar, paint, plaster, glazes and the like, consists according to Fig. 1 of a base plate 1 or frame, on which a plate 2 is placed in the middle on a bearing 3.

is mounted so as to be freely rotatable. A niche container 4 can be placed in the middle of the plate 2, which can also be designed as a grid or the like. This can be connected to the plate 2 by friction or by form. A vertical column 5 is attached to the side of the base plate 1. An agitator 7 is attached to an arm 6 on this column 5. The latter consists of a drive motor in the form of an electric or "combustion engine" or hydraulic or pneumatic motor. A shaft 9 is connected to the drive motor 8, at the lower end of which a stirring tool 10 is arranged. The latter is interchangeable and can thus be adapted to the respective mixing product. The boom 6 is mounted on the column 5 by means of a clamping bearing 11 so that it can be axially displaced and locked. The lower position of the boom 6 can be fixed by a stop 12 which can also be axially displaced and locked. Of course, a manually or motor-operated lifting and rotating device can also be provided in order to place the stirring tool in the most favorable position for mixing.

In order to adjust the rotational movement of the mixing container 4, a braking device 13 can be provided on the bearing 3 of the plate 2, the braking effect of which can be adjusted. In addition, the rotational movement of the mixing container 4 can be influenced by the more or less eccentric adjustment of the stirring tool 10. The length of the boom 6 is expediently dimensioned such that the stirring tool 10 is guided through the center 14 of the plate 2 or of the mixing container 4, as shown by the arrow 18 in Fig. 2. In order to facilitate the transport of the mixing device, the column 5 can be detachably attached by a clamping bearing 15 attached to the base plate 1.

It is clear that the rotational movement of the mixing container 4 depends on the eccentricity of the stirring tool 10 from the center 14 and its diameter, so that depending on the type of materials to be mixed, a suitable stirring tool 10 can be selected and thus the rotational speed can be predetermined in order to achieve a complete preparation of the mixed material in the entire mixing container 4. For example, if the stirring tool IQ rotates in the

Counterclockwise according to arrow 16 in Fig. 2, then the mixing container 4 also performs a rotational movement in the same direction, as shown by arrow 17. The closer the stirring tool 10 is rotated to the center 14, the smaller the reverse torque becomes and the higher the rotational speed of the mixing container 4 becomes.
