Definitions
- the present invention relates to a mixer with a mixing container and a tool shaft arranged at least partially in the mixing container, wherein the tool shaft has a working end, to which a working tool is fastened or can be attached, and a drive end, which is mounted by means of two tool bearings spaced apart from each other, and wherein a drive motor is provided with a motor shaft for driving the tool shaft.
- Such a mixer is known, for example from the DE 35 20 409 A1 ,
- the embodiment shown there comprises a pressure-resistant mixer with a filling opening, a rotating mixing vessel having an emptying device, with mixing tools arranged eccentrically to the mixing vessel axis in the interior of the mixing vessel.
- FIG. 1 shows a vertical section through a mixer.
- the mixer 1 has a mixing container 3 accommodated in a mixer housing 2, which can be rotated about a vertical axis of rotation. To ensure this rotation of the mixing container 3 is rotatably mounted on a ball bearing 4.
- the mixing container may have on its underside an emptying opening (not shown in the figure).
- the mixer housing 2 has a housing cover 5. Inside the mixing container 3, a working tool 6 designed as a mixing tool is arranged inside the mixing container 3, a working tool 6 designed as a mixing tool is arranged. It can be seen that the working tool 6 about a vertical axis, which is spaced from the axis of rotation of the mixing container 3, is rotatable.
- a drive end of the working tool 6 is guided through the housing cover 5 and driven by means of the drive motor 7 via, for example, V-belt 9.
- the work tools 6 are fixed to a tool shaft 8, which has a drive end to which the V-belt 9 engages, and a working end to which the working tools 6 designed as a mixing tool are fastened.
- the tool shaft 8 is formed in two parts in the embodiment shown, wherein the two parts can be connected to each other via the flange 10 or separated from each other. This flange 10 is among other things there, the working tool 6 against another working tool 6, such. B. one Star vortex against a pin vortex swap.
- the work tool if it shows signs of wear, be replaced with a new one.
- both the mixing container 3 and the tool shaft 8 rotate, it can lead to significant lateral forces on the tool shaft 8, which are caused by the material flow through the rotating mixing container 3, especially since the tool shaft is held only on one side in the housing cover 5.
- the size of the shear force depends inter alia on the type of mix and of course on the rotational speed of both mixing container 3 and the working tool 6.
- two tool bearings 11, 12 are provided at the drive end, each bearing the shaft with a diameter D.
- the tool bearings 11, 12 are bolted to the mixer housing 2 or the housing cover 5 via a flange 13.
- the V-belt 9 then engages the drive end of the tool shaft 8.
- the drive motor 7 has a motor shaft 20, which is also held by two motor bearings 14, 15. It can be seen that the diameter d 'of the motor shaft 20 is significantly smaller than the diameter D of the tool shaft 8.
- the belt transmission consisting generally of a set of multiple V-belts or timing belt, a maintenance-intensive machine element. These components must be checked at regular intervals for correct voltage and this must be adjusted if necessary. Likewise, both V-belts and toothed belts are subject to wear and must therefore be replaced at regular intervals.
- the GB 330834 also shows a mixer with a mixing container and a mixing shaft arranged in the tool shaft to which a working tool is attached. This drive shaft is driven by a drive motor.
- the DE 197 12 324 C2 and the DE 39 42 679 A1 show mixing devices for mixing liquids.
- the motors of the mixing device are held by means of rotor bearings.
- this object is achieved by a mixer according to claim 1.
- one of the bearings which is provided for the storage of the tool shaft, simultaneously used for the storage of the motor shaft.
- Motor shaft and tool shaft are therefore directly connected.
- the motor is arranged between the two tool bearings and the motor shaft is preferably mounted by means of the two tool bearings.
- the motor shaft is preferably mounted by means of the two tool bearings.
- the bearings for the tool shaft also serve as a bearing for the motor shaft.
- no distinction can be made in this embodiment between engine and tool shaft, since a portion of the shaft acts as a motor shaft and another portion of the same shaft as a tool shaft.
- a direct drive preferably a direct drive and more preferably a three-phase synchronous motor (servo motor, torque motor, reluctance motor) is used.
- a three-phase synchronous motor servo motor, torque motor, reluctance motor
- the bearing of the motor shaft facing the tool shaft is suitable for absorbing particularly high radial and axial forces. It is a combined radial thrust bearing (Radiax bearing), e.g. designed as a spherical roller or self-aligning ball bearings and particularly preferably as a double-row spherical roller bearings.
- Radiax bearing radial thrust bearing
- a further preferred embodiment provides that the diameter of the motor shaft differs at the two tool bearings, wherein preferably the diameter of the motor shaft d "on the tool shaft facing away from the tool bearing smaller, preferably at least 30%, more preferably at least 50% smaller than the diameter of the motor shaft D at the other tool bearing.
- the motor is expediently arranged in a motor housing, wherein both tool bearings are arranged on or in the motor housing.
- the motor housing having a first outer flange, with which the motor housing and thus the motor is fixed to the mixer housing.
- the motor housing having a second outer flange which is also secured to the mixer housing, wherein the second outer flange preferably has a larger average diameter than the first outer flange.
- the motor housing could for example have a circular cross-section, in which case expediently also the outer flanges have a circular cross-section. In principle, however, other cross sections, such as square or rectangular cross-sections are conceivable. Characterized in that the second outer flange has a larger average diameter, the motor can be easily attached to the mixer housing.
- the mixer housing may include a through-stage opening having a first smaller diameter portion and a second larger diameter portion, the second portion having a mean diameter greater than the mean diameter of the first outer flange and smaller than the average diameter of the second Outside flange is.
- the smallest mean diameter of the passage stage opening in the mixer housing is greater than the largest outer diameter of the working tool. By this measure, the entire work tool including the engine can be removed via the passage step opening.
- both flanges have holes for attaching the flanges to the mixer housing.
- the larger flange may have additional openings, which are preferably larger than the holes for attachment, which are provided so that a tool can access through the opening to the holes or fasteners in the smaller flange. This facilitates the attachment of the motor housing to the mixer housing.
- the tool shaft consists of two parts detachably fastened to one another, wherein one part is connected in one piece with the motor shaft, while the other part carries the working tool.
- the detachable connection can be made via a flange connection.
- the tool shaft may also be formed integrally with the motor shaft.
- FIG. 1 shows an embodiment of the prior art, which has already been described above.
- FIG. 2 shows a first embodiment of the invention.
- the drive motor 7 is accommodated in a motor housing 16, the motor housing 16 being fastened to the mixer cover 5 by means of two outer flanges 13, 17.
- the tool shaft 8 simultaneously acts as a motor shaft 21 at its drive end.
- the motor shaft 21, which is partially formed in the embodiment shown as a hollow shaft is held by the spherical roller bearing 18 and the radial bearing 19.
- the second outer flange 13, which faces the product space, ie the mixing container more, has a smaller outer diameter than the first outer flange 17.
- the entire motor can be inserted from the outside into the housing cover 5, so that first the outer flange with the smaller Outer diameter is inserted into a corresponding stepped bore in the container lid until it rests on the bottom of the extended bore.
- the distance between the two outer flanges 13, 17 is dimensioned such that in the in FIG. 2 shown situation, both flanges can be screwed to the housing cover 5.
- the engine can be easily detached and removed from the container lid.
- FIG. 3 which simultaneously shows a second embodiment of the mixer according to the invention.
- the engine including working tool 6 has been released from the housing cover 5, so that the engine including working tool 6 can be removed from the corresponding opening in the container lid.
- the embodiment shown differs from that in FIG. 2 shown embodiment in that the flange 10 is missing, so that here tool shaft and motor shaft are integrally formed.
- the axis of rotation of the working tool is arranged eccentrically to the axis of rotation of the mixing container.
