Definitions
- foam compositions in particular foam cement compositions and device therefor
- the invention relates to a process for producing foam compositions, in particular foam cement compositions, which essentially consist of a starting product, in particular cement paste, and a foaming agent, in a mixing reactor connected via a feed pump to a storage container for the starting product and a device to .
- Foam masses or foam cement masses are frequently used in modern building technology, particularly when renovating old buildings and when building new buildings.
- a compensation for height differences, depressions, cavities and the like must generally be applied to the raw floor in order to manufacture the further floor structure. This compensation is generally accomplished by installing foamed sheets and / or using loose fillings of dam materials.
- foamed sheets and / or using loose fillings of dam materials are very labor-intensive and therefore expensive. Furthermore, they are questionable from an occupational medical point of view.
- foam mass in which a different binder is used instead of cement, or foam cement mass is carried out by mixing air, water and a foaming agent into a foam.
- This foam is fed to a mixing device at the processing site and introduced into a cement paste consisting of cement and water.
- This manufacturing process is almost exclusively suitable for the production of a so-called heavy foam with a foam density of more than 800kg / m 3 .
- DE 41 18 537 C1 discloses a method for producing a so-called lightweight foam with a foam density between 250 and 400kg / m 3 and an apparatus for carrying out the method.
- cement paste is injected into a mixing chamber under high pressure and mixed with a foaming agent. Due to the high pressure, this mixture is fed to an expansion nozzle into which compressed air is blown in to foam.
- DE 36 31 223 AI shows a device for producing a hard foam composition with a fine pore structure, in particular a cement foam composition, which is fed to a pipe and is both forcibly transported and forcibly mixed by transport and mixing tools arranged in the pipe.
- the foam mass consisting of water and foaming agent is added distributed from the outside via the transport path formed by the tube. This is supposed to proportion of the foam mass that has a negative effect on the curing of the same can be reduced.
- DE 32 22 033 AI describes a process for producing a pore mortar with a low specific weight using compressed air.
- a device is used to carry out the method, which consists of perforated plates which are arranged one behind the other in a pipeline and through which the mortar mass flows. Appropriate connections introduce the compressed air into the pipe, where it mixes with the mortar.
- DE-A-23 48 915 discloses a system for producing foam cement, each with a volumetric pump for conveying water, foam agent, air and cement paste or mortar.
- the pumps for the water, the foaming agent and the air are connected to a foam-forming centrifuge, which is connected to a collector where the cement or mortar is required.
- the mixture is transported from the collector to a mixing machine at the point of use.
- the known devices and methods are disadvantageous insofar as the consistency and thus the quality of the foam compositions or foam cement compositions change due to the large number of mixing and delivery units connected in series. Furthermore, the known systems are only suitable for the production of foam compositions in a very restricted density range and are constructed in a very complex manner using a large number of auxiliary units. It is an object of the invention to provide a method for producing foam compositions, in particular foam cement compositions, of the type mentioned at the outset and a device for carrying out the method, which is used at a processing point and ensures a high quality of the foam compositions produced .
- the object is achieved according to the invention in that a product stream removed from the mixing reactor is fed in circulation with supply of the foaming agent and atmospheric air to the storage container kept at a minimum residual level, a partial stream being removed from the product stream for processing after a mixing phase.
- the product stream flowing continuously through the mixing reactor which essentially consists of the starting product stored in the storage container, the foaming agent and atmospheric air, is mixed with the starting product in an empirically determined mixing phase until a homogeneous foam mass of high quality is present.
- the mixing phase is ended and a partial stream is removed from the product stream for processing.
- the product stream is circulated through the mixing reactor, as a result of which its high qualttate and thus the qualltat of the partial stream is retained for processing.
- the starting product for example cement glue, is transported with a truck mixer to the storage container at the processing point, the transport capacity of which is not reduced by the foaming agent, since this is prepared separately. is posed.
- a compressed gas is preferably added to the product stream.
- the product stream is expediently passed to the reservoir via a jet pump.
- the foaming agent and / or the pressurized gas is added to the product stream in the jet pump.
- the amount of the foaming agent and / or the compressed gas added to the product stream is expediently measured and regulated. This measure allows the foam mass to be set to a desired density, which is necessary for processing. Furthermore, the foam agent and / or the pressurized gas is expediently required by a metering pump through a flow meter to the jet pump.
- the partial flow passes through a density measuring device.
- This continuously working facility is used to monitor the act of aggression Partial flow.
- the density of the partial flow is preferably determined volumet ⁇ sch or gravimet ⁇ sch. Furthermore, the partial flow m is preferably fed to the processing point or the storage container as a function of the result of the density measurement. A partial stream that does not meet the quality requirements is therefore not processed, but is reprocessed together with the product stream.
- the object is achieved in a device for producing foam compositions, in particular foam cement compositions, which essentially consist of a starting product, in particular cement paste, and a foaming agent, with a mixing reactor connected via a feed pump to a storage container for the starting product, in particular for Implementation of the aforementioned method according to the invention is achieved in that the mixing reactor has an outlet leading to a jet pump for a product stream, an outlet leading to a processing point for a partial stream of the product stream and an inlet for the product stream from the storage container, the product stream above the Fill level of the reservoir emerges from the jet pump.
- the mixing reactor is relatively compact and can be placed in the immediate vicinity of a processing point.
- the fact that the mixing reactor sometimes has a separate outlet and an inlet for the product stream and an outlet for the partial stream of the product stream means that these streams are circulated separately possible.
- a partial stream is only removed from the product stream, which is fed to the processing point when the product stream has the required quality.
- homogeneous mixing is achieved, which is to increase the quality of the foam mass.
- At least one mixing element is expediently arranged within the mixing reactor.
- the mixing element causes a swirling of the product stream and thus the generation of a uniform mass in the mixing reactor.
- At least one fine protection screen is preferably fixed within the mixing reactor.
- the fine protection screen is expediently arranged in front of the outlet for the product stream, the outlet for the product stream being located on a side of the mixing reactor opposite the inlet for the product stream.
- the mixing reactor is connected to an external ruttier.
- the ruttier is to be adjusted so that an already generated foam structure of the foam mass does not suffer any damage, after which a uniform and finely distributed air pore structure is retained in the foam mass. Since the vibrations of the mixing reactor are not intended to be transmitted to the storage container in full size, the mixing reactor is expediently connected to the storage container via a pipeline and a hose with the intermediate feed pump.
- the inside of the pipeline is preferably provided with at least one mixing element.
- the jet pump is provided with an inlet for the foaming agent and / or with an inlet for the compressed gas.
- the jet pump is preferably assigned a metering pump for supplying the foam agent and / or compressed gas flowing through a flow meter.
- connection line with an interposed density measuring device is expediently assigned to the outlet for the partial stream of the product stream. Furthermore, in order to control the amount of the partial stream discharged from the processing parts, the connection device with a volume meter connected downstream of the density measuring device.
- the density measuring device Since a partial flow that does not have the predetermined properties is not to be supplied for processing, the density measuring device is connected to a return line m, which leads to the storage container. Such a partial stream m the starting product or the product stream is thus introduced and reprocessed.
- the storage container is preferably covered with a protective screen.
- the jet pump for the product stream is assigned a metering jet pump for a partial product stream, which feeds the foaming agent and / or the pressurized gas to the partial product stream, after which the partial product stream enters the mixing reactor.
- a certain density of the partial product stream is set. After mixing the partial product stream with the product stream in the mixing reactor, the resulting density is required for processing.
- Fig.l is a schematic representation of an inventive device
- FIG. 2 shows a schematic illustration of part of the device according to the invention in an alternative embodiment.
- the device for producing a foam mass essentially comprises a storage container 1 for receiving an output product A, which is covered by a protective screen 2 and which is connected to a mixing reactor 4 via a feed pump 3.
- the feed pump 3 is connected on the one hand via a hose 5 to the storage container 1 and on the other hand by means of a pipeline 6 to an inlet 7 of the mixing reactor 4 for a product stream B.
- the inner wall of the pipeline 6 is provided with mixing elements, not shown.

Furthermore, the jet pump 11 has an inlet 21 for a compressed gas 22, which is also fed to the product stream B via a metering pump 23 with a downstream flow meter 24. The jet pump 11 is arranged such that the product stream B reaches the storage container 1 above the fill level 25 of the starting product A.
- the partial stream C of the product stream B is fed through a connecting line 26 to a density measuring device 27 with an upstream shut-off valve 28. Depending on the measurement result of the density measuring device 27, the partial flow C reaches the processing point 13 via a quantity meter 29 or the storage container 1 via a return line 30.
- the jet pump 11 for the product stream B is assigned a metering jet pump 31 for a partial product stream D.
- the product stream B reaches a driving nozzle 34 via a supply line 33 provided with a shut-off valve 32.
- the product stream B is mixed with air or gas 35, which is openly introduced into the jet pump 11.
- the jet pump 11 is followed by a diffuser 36 which flows into the mixing reactor 4.
- the partial product stream D is intimately mixed with the foaming agent 18 and the compressed gas 22, where 12
- a product stream B m is again passed from the mixing reactor 4 to the storage container 1 and a partial stream C to the processing point 13.
- the starting product A consisting of cement and water
- the storage container 1 is delivered by means of a truck mixer, which reaches the storage container 1 via the protective screen 2 m.
- the shut-off valve 28 for the partial stream C is closed and the product stream B is pumped into the circuit with the addition of foam agent 18, compressed gas 22 and atmospheric air and mixed in the process.
- the product stream B is removed from the storage container 1 by means of the feed pump 3, is conveyed to the mixing reactor 4 through the pipeline 6 provided with mixing elements, and is passed to the storage container 1 via the jet pump 11 m.
- the shut-off valve 28 is opened and the partial flow C flows through the density measuring device 27. If the measurement result corresponds to the requirements for the foam mass, the partial flow C is fed to the processing point 13 via the flow meter 29. If the measurement result does not meet the requirements for the foam mass, the partial stream C is introduced via the return line 30 into the storage container 1, after which further mixing takes place. During the removal of the partial stream C, the product stream B is required in the circuit described above. 13
