Definitions
- the present invention relates to a mixer and a method for producing a structure from building material using a mixer.
- Mixers with a drum are conventionally used to mix different components, which can be solid, liquid or powder, for example, in which a stirring shaft is arranged, which can be driven by a drive.
- the agitator shaft can be equipped with pins, for example, so that when the agitator shaft rotates, the mix is moved and mixed.
- Such a mixer is for example in the published patent application WO 2007/066362 A1 shown. With this horizontal continuous mixer, the material to be mixed is fed into the drum via an inlet, mixed there by pins on the agitator shaft, and finally discharged from the drum again via a side outlet.
- the pins on the agitator shaft of such a mixer can be designed and arranged in such a way that the mix is moved in a predetermined direction in the drum by the pins.
- it has been shown that such movement of the material to be mixed through the drum of the mixer only works sufficiently well with certain viscosities of the material to be mixed.
- the conveyance of the mixed material to an outlet of the mixer is insufficient. The consequence of this is that the mixer can become blocked and its function is impaired.
- a mixer is to be made available which can continuously mix and convey substances with a higher viscosity.
- the mixer should also be easy to use and inexpensive to use.
- the object is first achieved by a mixer comprising a drum with at least one inlet and one outlet.
- the mixer further comprises a drive and an agitator shaft for mixing a material to be mixed, the agitator shaft arranged in the drum being coupled to the drive.
- the Mixer a conveyor device which is arranged in the drum and which is arranged on the same axis as the agitator shaft.
- This solution has the advantage that it can also continuously mix and convey mixes with higher viscosity. For example, when mixing pumpable concrete with concrete admixtures, it is desirable for the mix to reach a certain viscosity so that it can be used directly to produce a concrete structure.
- the conveyor device according to the invention in the mixer also allows the material to be mixed to be conveyed continuously and directly from an inlet of the drum to an outlet of the drum for such applications, without the mixer being blocked by more viscous mixing materials and thus failing in its function.
- the conveying device is arranged directly on the agitator shaft, so that the mixed material mixed by the agitator shaft can be picked up directly by the conveying device and can be conveyed out of the drum through the outlet.
- the agitator shaft is equipped with pins, so that when the agitator shaft rotates, a mixture in the drum is moved by the pins.
- Such agitator shafts with pins are particularly suitable for mixing components with large grain sizes, for example grain sizes of 2 to 10 mm.
- This can be, for example, aggregates such as stones, gravel or sand.
- a mixer is also suitable for mixing asymmetrical substances such as, for example, mixed materials with fiber additives (for example carbon fibers, metal fibers or plastic fibers).
- the agitator shaft is not equipped with pins, but instead is designed, for example, as a spiral stirrer, disk stirrer or inclined blade stirrer.
- the conveying device and the agitator shaft are arranged on the same drive shaft, this drive shaft being drivable by the drive. This has the advantage that it results in an inexpensive and robust device.
- the conveyor device and the agitator shaft are arranged on two separate drive shafts, the conveyor device being arranged on a first drive shaft and the agitator shaft on a second drive shaft, so that the conveyor device and agitator shaft can be driven at different speeds.
- Such an arrangement has the advantage that the mixing and conveying of the mixed material can be set separately from one another. In this way, mixing and conveying that is optimal for the respective purpose can be achieved by means of a specifically adaptable mixing capacity and conveying capacity. For example, for a first application a slight mixing with a simultaneously high delivery rate and / or delivery with high pressure may be advantageous, and for a second application a strong mixing with a simultaneously low delivery rate and / or delivery with low pressure may be advantageous.
- the agitator shaft and the conveyor are arranged side by side in the drum, the agitator shaft being arranged on a first drum section and the conveyor device on a second drum section, and the inlet on the first Drum section and the outlet are arranged on the second drum section.
- the first drum section with the stirring shaft arranged therein forms between 50% and 90%, preferably between 60% and 85%, particularly preferably between 70% and 80%, of a volume of the drum. It has been shown that by dividing the drum in this way, an optimal mixing performance can be achieved with a desired delivery capacity of the mixer.
- the conveyor element is designed as a screw conveyor.
- the screw conveyor has at least one, preferably at least two turns. Such a screw conveyor has the advantage that it can also convey highly viscous mixes in the drum and can also be conveyed out of the drum at a desired pressure through the outlet.
- turns can be formed.
- the turns can differ in their dimensions in the direction of the drive shaft, the turns becoming narrower towards one end of the conveying device.
- a delivery pressure of the delivery device can be changed, depending on the orientation of the narrowing of the turns.
- a cross section of a shaft of the conveyor device can be designed to be variable in the direction of the drive shaft.
- a volume for the mix becomes narrower towards one end of the conveyor.
- a conveying pressure of the conveying device can be changed, depending on the alignment of the narrowing of the volume for the mix.
- only one inlet or also two or more inlets can be arranged on the drum.
- the components can be brought together, for example, before they are passed into the drum, or the components can be guided into the drum via separate inlets and only in the Drum to be mixed together.
- the agitator shaft and any agitating elements arranged thereon, such as pins can be designed differently.
- the drum comprises a first inlet and a second inlet, a feed device being arranged at the first inlet.
- a feed device being arranged at the first inlet.
- the feed device comprises a funnel for receiving a powdery component, a second drive and a second agitator shaft coupled to it and arranged in the funnel. This has the advantage that this powdery component can be continuously introduced into the mixer drum without clogging.
- the second agitator shaft comprises radially arranged agitator blades, which are arranged in an input region of the funnel, and wherein the second agitator shaft has an axially aligned stirring rod which is radially offset from an axis of rotation of the agitator shaft and which is arranged in an output region of the funnel.
- stirring blades without a stirring rod or a stirring rod without stirring blades can be arranged on the stirring shaft.
- a component that is fed to the system via the feed device can be fed using a gravimetric method.
- a gravimetric method In contrast to a volumetric method, this has the advantage that a supplied mass of the one component can be set precisely, as a result of which a more precise mixing result can be achieved.
- an additional second conveying device is arranged in the drum on the same axis as the agitator shaft and the conveying device in order to lead a first component introduced into the drum through the inlet away from the inlet before the first component is mixed with further components.
- a system for applying a building material comprising a travel device, a first component and a second component.
- the system further comprises a mixer for mixing the first component and the second component, the mixer being arranged on the travel device and being movable by the latter.
- the first component and the second component for producing the building material can be fed to the mixer.
- the building material generated from the components can be applied via the outlet of the mixer.
- the mixer according to the invention and described here is used as the mixer.
- Such a system for applying a building material offers the advantage that, for example, building structures can be built efficiently and cost-effectively.
- the advantage of the arrangement proposed here is, in particular, that the components are only mixed with one another shortly before the application of the building material. This is made possible by the fact that the mixer is arranged such that it can be moved via the travel device, so that it can be brought to the position at which the building material is to be applied. Due to the direct application of the building material after the mixing process, a highly viscous building material, such as concrete, can be used in the mixer without this highly viscous building material having to be conveyed or processed further.
- the first component is a pumpable building material such as concrete
- the second component is a pumpable substance that contains a building material additive such as a concrete additive.
- the building material additive is a solidification accelerator and / or a hardening accelerator.
- a pumpable building material and a building material additive offers the advantage that both the pumpable building material and the building material additive can be transported from a container to the mixer in a simple manner, the mixing of these two substances resulting in a highly viscous building material which is used directly for Manufacturing a building structure can be used.
- the traversing device is designed to be movable in the manner of a 3-D printer, so that structures can be built up from the building material by means of the system.
- a method for producing a structure from building material comprising the steps: mixing a pumpable building material, in particular concrete, and a pumpable substance which contains a building material additive, in particular a concrete additive, with a mixer; and applying the mixture with a moving device.
- the concrete admixture is a setting accelerator and / or setting accelerator.
- the mixer is operated at a speed of more than 500 revolutions per minute, preferably at a speed of more than 650 revolutions per minute, particularly preferably at a speed of more than 800 revolutions per minute, particularly preferably at a speed Speed of more than 1000 revolutions per minute.
- pumpable concrete which was mixed with fibers, was mixed with accelerator at different speeds according to the method described above.
- speeds of over 900 revolutions per minute have proven to be advantageous, because in addition to the concrete, the fibers also had to be broken up here.
- the average residence time of the mixture in the drum is less than 10 seconds, preferably less than 7 seconds, particularly preferably less than 4 seconds.
- the average residence time of the mixture in the drum is the length of time that a particle remains in the drum (from the inlet of the drum to the outlet of the drum) on average.
- An above-mentioned advantageous average residence time of at most a few seconds has the advantage that a mixture of high or strongly increasing viscosity can be conveyed, such as pumpable concrete mixed with solidification accelerators and / or hardening accelerators.
- the mixture when the mixture is applied, the mixture is applied in a plurality of at least partially superimposed layers.
- an existing layer is only overlaid with a new layer of the mixture when the existing layer has sufficient strength to maintain an original shape.
- layers of the mixture which are at least partially overlapping are continuously built up during application, so that the structure is built from building material in the manner of a 3-D printer.
- Such methods offer the advantage that entire structures can be produced from building material, such as building walls or the like. In comparison to conventional methods, such methods offer the advantage that no formwork is necessary and that the shape of the structure can therefore be selected much more freely.
- FIG. 1 An exemplary mixer 1 is shown.
- the mixer 1 has a drive 3, a drum 2, an agitator shaft 4 and a conveying device 5.
- the drum 2 has two inlets 6 and one outlet 7.

- the conveyor device 5 is designed in this embodiment as a screw conveyor.
- the screw conveyor in this exemplary embodiment has two complete turns 9. Depending on the desired conveying capacity, the screw conveyor can be dimensioned or designed differently.
