Definitions
- the invention relates to a positive mixer for production of mixtures of liquid, powdery and granular Components such as Concrete mixtures.
- Such a mixer is known from DE 31 10 437 A.
- the outer agitator is designed as a worm gear, which in a movement encircling the mixer vessel wall is transferred.
- the inner and outer mixer screw promote upwards.
- EP 0 796 708 describes a mixer with an inner and described an external agitator. While that as Worm gear trained internal agitator the mix Conveying upwards, it is the job of the outer agitator forming coulters, the mix in the outer area of the Convey mixing container down and to the middle. in this connection the outer agitator is slower Rotation speed, but in the same direction as that to let the inner agitator circulate. Because the direction of rotation the outer agitator does not change during the mixing process, however, unmixed material can last for a long time Period before the coulters are pushed in and out for this reason are only slowly worked on.
- the object of the invention is a mixer of the type described Way of creating, especially as a concrete mixer is suitable and with the unmixed material which is pushed in front of the coulters, is mixed in narrowly.
- the external agitator becomes intermittent first in one direction of rotation and then in the other Direction of rotation alternately moved. This ensures that unmixed Material pushed in front of the coulters is mixed in quickly.
- An internal agitator 2 in is in a funnel-shaped mixing container the central axis 3 of the mixing container 1 attached that from a shaft 4 and a cylindrical or attached thereto conical screw 5 or helically arranged wings consists.
- This agitator 2 extends directly to the Lock slide 6 and is on the opposite Side driven by a drive 7.
- An external agitator with mixing arms 8 and attached blades 9, which the coat the surface of the mixing container 1 touched by the mix, is mounted coaxially to agitator 2 and by the drive 10 driven. Both drives 7 and 10 can also are infinitely variable.
- the Drives 7 and 10 and the mixing container 1 are on one Support structure 11 attached, which in turn rigid or over rubber-elastic pads 12 is connected to the system 13, if a vibrator 14 is used on the mixing container 1 should.
- the mixing container is at its outlet end with the help of a Seal 17 and the shutter operated by the actuator 15 6 sealed for transferring the mix a tube or hose 16 is used in the transport container.
- This embodiment has the advantage that the outer agitator the material in both directions pushes off the wall.
- the mixing arms 8 are designed that the coulters face the container wall surface Adjust the bottom to the direction of the wall.
- the mixing arms 8 and the shares 9 are in for this purpose vertical direction and at an angle to the container wall adjustable.
