Definitions

  • the invention relates to a method and a device for mixing mortar, plaster, concrete or the like.
  • wet mixtures e.g. Lime milk
  • the free-flowing material being fed to a metering device and then mixed with liquid, mixed and conveyed at the same time, the substantially dry material or mix being fed to the metering device from a loading container and the mixture after being mixed with liquid in a downward direction and is guided, conveyed and mixed in an approximately horizontal direction.
  • DE-A-27 01 508 has already disclosed such a method for preparing setting material.
  • the metering device is followed by a vertical mixing device, within which the dry material is subject to gravity. Near the lower end of this vertical mixer, the liquid is supplied for mixing, so that within the vertical mixer for the actual mixing process between the initially free-flowing dry material and the liquid there is hardly any time left.
  • the actual mixing process for mixing or mixing takes place in a horizontal mixing device located below the vertical mixing device, so that the above-mentioned vertically arranged mixing device more represents the role of a transfer station for the material and the liquid.
  • the required dwell time of the mix for mixing is aimed at in the connected horizontal mixing area.
  • EP-BO 051 224 has therefore disclosed a method and a device for the continuous preparation, in particular of building material mixtures, with water, in which the material is conveyed substantially horizontally after leaving the loading container, the mixing zone, in which the water is supplied, being arranged horizontally behind the metering device and the material mixed with water being subjected to counter-conveyance before it leaves the mixing zone which is less than the funding in the funding direction.
  • a device for mixing and conveying building materials is also known from DE-AS 28 02 683, in which the mixing container can be pivoted about an essentially horizontal axis passing through the center of the recess provided in the wall of the respective storage container, so that it is optionally arranged horizontally, at an angle or vertically. This should make it possible to adapt to different grain structures in the mixture. However, an extension of the dwell time in the mixing area and, above all, an increase in air pore formation is not possible, unless special chemical air pore formers are added.
  • Another device for continuously mixing a building material with water is from DE-OS 24 07 657 known.
  • the loading container is arranged on the side of the mixing device and contains an inclined feed wheel which conveys the mixture from the storage container in its upper edge region and into the upper inlet of the vertical mixing device. Mixing takes place in the vertical mixing tube, so that again only a very limited mixing time is available.
  • the invention is therefore based on the object of providing a method and a device of the type mentioned at the outset, with which the advantages of metering the substantially dry mixture before the addition of mixing liquid or mixing water and mixing with this liquid are retained in an approximately horizontal direction , but still the dwell time without the risk of a backlog of moisture in the dosing area increased significantly, thus intensifying the entire mixing process and possibly improving the mixing in of air, without the entire mixing device - possibly underneath the loading or storage container or silo - being too long and too long protrudes well beyond the outline of this container.
  • the best possible supply of the prepared mixture to a pump that conveys it should be possible, whereby inhomogeneities should be avoided as far as possible even after a certain wear of the pump.
  • the solution to this apparently contradictory task according to the invention consists in the process that the mixed liquid mixture is first conveyed and mixed in an approximately horizontal and then in a downward direction.
  • the mixture is deflected from the approximately horizontal conveying direction into a vertical or almost vertical direction.
  • it can again be thoroughly mixed with entrained air, the gravity and the deflection promoting the entrainment of air and also the supply to a feed pump located below the vertical mixing zone.
  • a device for performing the aforementioned method according to the invention can consist in that a downwardly directed mixing chamber is connected to a mouth of a substantially horizontally arranged mixing chamber with a horizontal mixing shaft, in which another mixing tool rotates, and that Connection for supplying the liquid to the initially dry material or material to be mixed is provided at the horizontal mixing chamber at a distance from its mouth.
  • the downward-pointing mixing chamber can expediently be arranged approximately vertically and have entry into a feed pump at its lower mouth. This also enables a convenient and inexpensive arrangement of the mixer shaft, the motor of which can be arranged above this vertical mixing chamber, while the motor for the horizontal mixing device can be mounted in a known manner, for example in front of the feed area of the mixing device.
  • An inlet opening for air and for observing the mixing process can be provided above the vertical mixing chamber. This allows good monitoring of the mixture and, moreover, there is the possibility that, in the event of an unwanted jam, due to the conveying movement of the horizontal mixing tool, the material taken up is kept away from the dry metering area and discharged through this overflow opening. Since the mixture already contains water in this area, there is no dust at the opening.
  • the vertical mixing chamber can be very simple in construction, since it does not require any precautions for the supply of water and for sufficient retention of the mixture in this area exposed to gravity in order to ensure thorough mixing with the To cause water, because this mixing in the horizontal area can already be largely completed and the ver tical area only serves to strengthen the mixture and to enter air pores. Nevertheless, the overall length of the device is not, or not significantly, increased since, in contrast to the main mixture, this post-mixing does not take place in the horizontal but in the vertical direction.
  • An embodiment of the invention of considerable importance can be that a probe, a sensor or the like in the downward mixing area. Arranged sensor which controls at least the drive of the horizontal mixing device and / or water supply. Should there be a backflow in the vertical area due to a too small decrease in the finished mixture with the feed pump, the further replenishment from the horizontal area can be switched off in good time so that an overflow at the overflow opening is avoided.
  • the vertical mixing chamber can be arranged via a joint, hinge or the like arranged to the side of the mouth of the horizontal mixing chamber. with preferably a vertical pivot axis from the mouth of the horizontal mixing chamber can be pivoted away. This makes the horizontal mixing chamber easily accessible for cleaning. At the same time, this results in an even better cleaning option for the vertical mixing chamber, because it then both from the then open inlet opening as well as can be flushed out from the ventilation or overflow opening.
  • the motor for the vertical mixing drive can simultaneously drive the feed pump, which is preferably arranged coaxially thereto.
  • a design which improves the handling of the device, in particular the removal of the horizontal mixer shaft e.g. can facilitate cleaning purposes, may be that at the end of the horizontal mixing chamber an axial stop is provided for the end face of the horizontal mixer shaft, which stop - especially when the vertical mixing chamber is removed - can be moved away from the mouth of the horizontal mixing chamber, preferably pivoted away.
  • This measure has the considerable advantage that the mixer shaft can be driven at its end opposite the mouth of the mixing chamber by means of a simple plug-in coupling, because it is held in the axial direction by the stop. If this stop is moved away, the mixer shaft can simply be pulled forward out of the mouth of the horizontal mixing chamber without any special effort.
  • the stop for the end face of the horizontal mixer shaft is designed as a flat plate, at least on the side facing this mixer shaft.
  • the stop is attached to the housing of the vertical mixing chamber and can be pivoted away from it with the mouth of the horizontal mixing chamber.
  • Another solution is to swing the vertical Allowed mixing chamber without axial release of the mixer shaft, may consist in that the stop is articulated independently of the vertical mixing chamber on pivot hinges, which are opposite the pivot hinges for the vertical mixing chamber at the mouth of the horizontal mixing chamber, and that a holder for the stop in its position of use is provided.
  • the vertical mixing chamber can thus be pivoted about its hinges with respect to the horizontal mixing chamber and the stop can be kept in the position of use.
  • the vertical mixing chamber has been swung open, it in turn can be opened and pivoted away from the mouth of the horizontal mixing chamber in order to make the horizontal mixer shaft accessible with the mixing tools.
  • the lower edge of the side opening can be at the level of the lower limit of the metering channel or slightly lower. If accumulated material builds up, it can flow out through this opening before it can be accumulated through the horizontal mixing chamber up to the dosing area.
  • a further embodiment of the device according to the invention can consist in that more than one horizontal mixing chamber with water connection, preferably two horizontal mixing chambers, in particular opposite one another, open out at the vertical mixing chamber. This results in the considerable possibility of merging two largely mixed mixtures and finally verifying them vertically mix, which is particularly useful for those mixtures that have a large number of components. Another possibility is to use a second horizontal mixing chamber, for example, for color components or the like. feed, which could also happen through the side opening.
  • the mixing tools can therefore only be used to produce an intensive mixing action and thereby also form a trombone, whereby this trombone can also have a good suction effect for air in a vertical arrangement of the downstream mixing tools, so that a correspondingly large number of air pores without chemical additives can be entered.
  • This intensive processing of the mixture does not practically increase the extent of the device transversely to the axis of a storage silo, under which the device can be attached directly, so that the road transport of such a storage silo with a mixing device attached to it remains possible.
  • Another significant advantage of the device according to the invention and the corresponding method is in that both the pre-mixing time and the post-mixing time can be controlled, for example by different engine speeds and running times, since each mixing area and each mixing device has its own drive motor.
  • a device designated as a whole by 1, shown in detail in FIG. 2, is used for mixing mortar, plaster, concrete or the like. setting material with a liquid, this material according to FIG. 1 coming from a storage silo 2 with feet 3 into a loading area 4.
  • the entry 5 of the loading area 4 of the device 1 could also be with another, e.g. a smaller loading container for bagged goods can be loaded; if necessary, several inlets 5 could be provided in the loading area 4, for example an inlet 5 connected to a storage silo 2 and an adjacent inlet 5 for bagged goods.
  • the material reaches a metering device 7 with the aid of a screw conveyor 6, which in the exemplary embodiment is formed by a metering screw 8 coaxial with the screw conveyor 6 in a metering channel 9.
  • the metering device 7 opens into a mixing chamber 10 which has an inlet 11 for liquid, preferably water.
  • a mixing chamber 10 which has an inlet 11 for liquid, preferably water.
  • this mixing chamber 10 like the metering device 7 and also the loading container 4, being arranged essentially horizontally and penetrated by a coaxial shaft 13 which has a drive motor 14.
  • this second mixing chamber 16 is arranged vertically and has a feed pump 20 at its mouth 18 below its mixing tools 17 coaxial with its mixer shaft 19. A deflection of approximately 90 ° therefore takes place from the mixing chamber 10 to the mixing chamber 16.
  • the mixer shaft 19, which is directly connected to the feed pump 20, has its own drive motor 21, which is arranged above the vertical mixing chamber 16.
  • the mixture can thus be guided and conveyed in an approximately horizontal direction when being mixed with water and then deflected in a downward direction and mixed further in this downward region.
  • the mixing tools 17 in the vertical mixing chamber 16 can generate a vortex in the mixture, which can suck air into the mixture in order to increase the number of air pores.
  • this additional mixing chamber 16 hardly increases the extent of the device 1 transversely to the silo axis, so that the device 1 can still be conveniently accommodated approximately in the outline of the storage silo 2, that is to say with the silo 2 can be transported together on a road vehicle.
  • a probe 24 can be arranged which can at least control the drive of the horizontal mixing device and / or the water supply.
  • Fig. 1 it is also indicated that the vertical mixing chamber 16 with the feed pump 20 attached thereto and the drive motor 21 is arranged pivotably away from the mouth 15 of the horizontal mixing chamber 10 via a joint or hinge 25 arranged laterally of the mouth 15 with a vertical pivot axis.
  • This results in good accessibility of the horizontal mixing chamber 10 from its mouth 15, so that cleaning of this area is possible in a simple manner.
  • this results in an improved cleaning possibility for the vertical mixing chamber 16, which is then accessible from the exposed opening for the mouth 15 and - if present - from the opening and can be flushed through.
  • the vertical mixing chamber 16 could, if necessary, even be detachably attached to the horizontal mixing chamber 10, so that it could be removed or could remain in those cases in which such an intensive mixing of the material, especially with air, is not required. This allows the versatility of the device 1 to be increased. If a relatively short mixing time is sufficient, the vertical mixing device or the mixing chamber 16 can either be pivoted out of the mouth region 15 with the aid of the hinge 25 or removed completely, so that the mixture behind the horizontal mixing chamber 10 can then be removed immediately.
  • a mixing device with a horizontal mixing chamber 10 can also be provided retrospectively with a vertical mixing chamber 16 with a mixing tool 17, feed pump 20 and drive motor 21, so that the already known and existing approximately horizontal mixing devices can subsequently be used in the manner according to the invention.
  • the mixing chamber 10 could possibly be shortened compared to the exemplary embodiment, so that the vertical mixing area can be accommodated even better within the silo outline, because the addition of the two mixing chambers 10 and 16 intensified into a shortened mixing chamber 10 Mixing the prepared material with water and air leads.
  • the device 1 can be used continuously or in batches, in the former case the pump 20 continuously conveying the material which has been mixed and which was previously mixed.
  • the feed pump 20 is occasionally switched off, so that at least after a certain backflow time, the mixing device 12 and thus the further supply of dry material is then preferably interrupted via the probe 24.
  • an axial stop 26 is provided for the end face of the horizontal mixer shaft 13 at the end of the horizontal mixing chamber 10, which stop 26 in turn moves from the vertical mixing chamber 16 when the vertical mixing chamber 16 is moved away from the mouth 15 of the horizontal mixing chamber 10
  • the mouth 15 can be moved away, preferably swung away, so that the mixer shaft 13 with the mixing tools 12 is accessible from the mouth 15 and can be pulled out for cleaning or repair purposes, for example.
  • This has the advantage that a simple plug-in coupling for the drive is sufficient at its end facing away from the mouth 15.
  • This stop 26 is designed in a practical and simple manner as a flat plate.
  • this stop is 26 attached to the housing of the vertical mixing chamber 16 and thus together with this pivotable away from the mouth 15 of the horizontal mixing chamber 10 about the hinges 25.
  • Fig. 4 shows a solution in which the stop 26 is articulated independently of the vertical mixing chamber 16 on pivot hinges 27, which are opposite the pivot hinges 25 for the vertical mixing chamber 16 at the mouth 15 of the horizontal mixing chamber 10, these pivot hinges 25 in Fig. 4 are not shown for better clarity.
  • a holder 28 can be seen schematically in FIG. 4, by means of which the stop 26 can be fixed in its position of use, so that it is not inadvertently also pivoted open when the vertical mixing chamber 16 is pivoted away.
  • the plug-in coupling 29 mentioned for the mixer shaft 13 is indicated schematically in FIG. 2 at the end of the metering area 9.
  • the lower edge 30 of the lateral opening 22 is arranged at the level of the lower limit of the metering channel 9 or somewhat lower, so that in the event of a backlog of material in the vertical mixing chamber 16, this material does not reach the metering area 9 can reach and moisten the material that is still dry there, but can emerge from the opening 22 beforehand. This therefore represents an additional safety measure for the probe 24 and could even make a probe 24 unnecessary in simpler embodiments.
  • FIG. 5 shows an embodiment in which two horizontal mixing chambers 10, approximately opposite one another, open at the vertical mixing chamber 16 Mixing products in the vertical mixing chamber 16 can advantageously be mixed with one another.
  • the structure of the horizontal mixing chamber 10 and the vertical mixing chamber 16 corresponds to the previously described embodiments.
