Definitions

  • the invention relates to a method for the continuous preparation of mortar, plaster, concrete or the like. Building material or material, wherein the material is fed to a metering device and then mixed with liquid and at the same time mixed and fed to a discharge opening.
  • the invention further relates to a device for the continuous preparation of such materials with a feed or loading device, an adjoining dosing device for the dry material, a liquid addition point and a preferably tubular mixing container with a discharge opening for the prepared material.
  • the solution to this problem essentially consists in exposing the mixture to a longer dwell time in the area of the water supply and / or in the conveying direction behind it and stirring it in the meantime. Tests have shown that in this way the proportion of air pores within the finished mixture could be increased considerably.
  • a particularly expedient embodiment of the method according to the invention can consist in that the material is stowed after the metering and the addition of water while stirring, while at the same time an amount of material exceeding the stowed amount emerges from the mixing area.
  • the material is stowed after the metering and the addition of water while stirring, while at the same time an amount of material exceeding the stowed amount emerges from the mixing area.
  • the invention also includes a device for the continuous preparation of mortar, plaster, concrete or the like material, a metering screw being provided in the metering area and a rotating axis in the mixing container with stirring or mixing tools and conveying blades or the like while a discharge opening is arranged at the end of the mixing chamber.
  • a device for the continuous preparation of mortar, plaster, concrete or the like material a metering screw being provided in the metering area and a rotating axis in the mixing container with stirring or mixing tools and conveying blades or the like while a discharge opening is arranged at the end of the mixing chamber.
  • at least one baffle element which at least partially and temporarily restricts the material to be mixed and which partially covers the cross section of the discharge opening and / or the end of the mixing chamber, is preferably arranged in the region of the material to be mixed.
  • the mixing material discharge opening can have a smaller cross-section stowing the material to be mixed than the cross-section of the cylinder of the mixing chamber gripped by the mixing tools.
  • the desired stowage of the mix can take place in the mixing chamber and there can be a corresponding sump are formed, which not only leads to a longer dwell time, but exposes the mix to a more frequent exposure to the mixing tools, so that more air is introduced accordingly. It was found that the air pore content from originally about 6% to e.g. B. 16 to 18% or even more could be increased.
  • This embodiment of the invention can be designed in such a way that the cross section of the discharge opening of the mixing head is at least 20% smaller than the cross section of the mixing space covered by the mixing tools.
  • the cross section of the discharge opening can be 22 to 42%, preferably 25 to 30% smaller than the cross section of the cylinder gripped by the mixing tools. If the mixing head cannot be rotated, the discharge opening can be designed asymmetrically to the mixing shaft and have a greater distance from the edge of the mixing chamber on its lower side than on its upper side.
  • the discharge opening can be surrounded by a preferably replaceable dust cover. Further expedient configurations are possible and contained in the subclaims.
  • a modified embodiment of the invention of considerable importance can consist in the fact that the mixing chamber in the area in front of and / or at the discharge opening in the conveying direction can have a narrowing, preferably tapered longitudinal section and that in this area preferably one with its outer edge on the slope the taper adapted stirring tool is arranged.
  • the material jam results from the fact that the material must rise above this incline towards the end of its conveying in the mixing chamber, that is to say it is exposed to a certain counterforce or counter-conveying. A certain congestion can thus be generated by this increase, the one possibly provided for the inclined mixing tool can also introduce more air pores into the material in this area. It is sufficient if at least the bottom of the mixing chamber rises in front of and / or at the discharge opening.
  • Another embodiment of the invention of its own worthy of protection may consist in that at least one damming element is attached to the shaft carrying the mixing tools and rotates with it.
  • this baffle element can in turn participate in the mixing process by its movement and, with a corresponding design, can support the introduction of air into the mixture.
  • baffle element for example, a disk, a ring or the like can be attached to the shaft, which has openings or the like orifices in the interior and / or on the outside opposite the mixing chamber housing.
  • the damming element fastened to the shaft can carry projections, wings, blades or the like, so that this element has a double function by, on the one hand, jamming the material in the desired manner and, on the other hand, additionally using it as a mixing and stirring tool due to its rotation becomes.
  • the oppositely effective wings, blades or the like can NEN have approximately the same conveying effect as the overall conveyor blades or blades provided in the mixing area, so that the material feed can be carried out by the pressure exerted by the metering screw in the conveying direction.
  • a particularly expediently designed and well-effective device results if at least one row of conveying vanes located on the circumference of the shaft or axis is arranged at the beginning of the mixing chamber and at the end the baffle element, in particular the opposing vanes, and mixing or stirring tools which are neutral in terms of conveyance.
  • the material is mainly stirred over most of the mixing chamber and a corresponding amount of air can be mixed in.
  • the mixing and stirring tools can be designed as grids, perforated plates or the like, which can improve the introduction of air.
  • a considerable advantage of the rotating dam elements is that the mixing chamber has a substantially constant cross-section, possibly tapering at the end, over its entire length, so that enlargements of the chamber or the like can be avoided.
  • a z. B. placed on a chassis device for mixing mortar has an inlet funnel 1 and a connector 2. The latter leads to a horizontally running loosening space 3.
  • An electric motor 4 is connected to one side of this loosening space, the horizontally running shaft 5 of which has blades 6 in the loosening space, which convey the loosened dry material to a dosing screw 7.
  • the cylindrical space captured by the dosing screw 7 has a much smaller diameter than the loosening space 3.
  • a mixing device or mixing chamber 8 is connected to the metering device, which has a water addition 9 and is detachably flanged to the tubular part forming the loosening space and the metering space.
  • the shaft 5 has a shaft coupling 10 so that the shaft just mentioned also extends straight into the mixing chamber 8.
  • the mixing tools 11 can be conventional mixing paddles, some of which provide for the mixing and some of which promote the mixing material.
  • a mixing head 12 is connected to the mixing chamber 8, which likewise has a tubular cross section and has an approximately 60% larger diameter than the tubular mixing chamber 8.
  • mixing and transporting tools 13 are connected, which, like the mixing and transporting tools 11, ensure mixing and conveying of the mixed material to the right in the drawing.
  • the mixing head 12 is closed by a dust cover 14, which can be detachably and interchangeably attached to the mixing head.
  • the shaft 5 or at least the part of the shaft 5 supported by the shaft coupling is rotatably mounted in a holder 16 at the end of the mixing head.
  • the discharge opening 17 of the mixing head is considerably smaller than the diameter of the same.
  • the mixing head and the mixing chamber are non-rotatably connected to the metering device, in which case only the lower region 18 of the dust cover 14 is of crucial importance because, as explained in more detail below, only the lower area of the mixing head 12 is decisive for the jamming effect.
  • the fact that the dust cover 14 also constricts the discharge opening 17 in the area 20 opposite the discharge chute 19 is only important because, due to the mixing and transport performance of the mixing tools 13, 12 mixed material could also escape in the upper area of the mixing head.
  • the discharge opening 17 is substantially smaller than the entry opening 22 of the Mixing head, so that the sump 21 at the height of the inlet opening 22 has a lower height than at the height of the discharge opening 17th
  • the mixing head 12 can also be connected directly to the metering device or metering screw 7 with omission of the mixing chamber 8. The effect described below is not affected very much.
  • the discharge opening 17 can also be arranged asymmetrically, since, as already mentioned above, the effect according to the invention depends on the height of the dust cover in the area 18 and the upper area 20 only as protection for unintentionally escaping Mixed material must be provided.
  • the hopper 1 can also be provided below a silo and the device according to the invention for mixing mortar can be connected to the silo in a fixed or detachable manner.
  • the use of the mixing head 12 not only leads to a more intensive mixing action of the material to be mixed, but above all to a decisive increase in the air pore content. If, as usual, only a mixing chamber 8 is provided with a discharge opening corresponding to the cross section of the same, for example an air pore content of e.g. B. 6 to 7% reached while it by switching the mixing head 12 to z. B. 16 to 18% is increased.
  • the use of the mixing head 12 results in a significantly increased dwell time compared to a known or conventional continuous mixer. While in a normal mixer with a length of approx. 55 to 60 cm, the mix is exposed to the mixing process for about 10 seconds, with about 6 to 7 liters of mix being subjected to the mixing action, the mixing head 12 increases to 30 to when the mixing head is used 40 sec., 16 to 18 liters of mix being subjected to the mixing action.
  • the normal flow height below the mixing tools is approximately 45 to 50 mm, while at the outlet of the mixing chamber 8 (without mixing head 12) there is only a flow height of the material of 15 to 25 mm.
  • the special design of the dust cover 14 increases the sump on the discharge side to approximately 85 mm.
  • the agitator speed with a mixing tool diameter of 180 mm on the outer edge of the mixer 2.55 m / sec. at 272 rpm. is, with a diameter of the mixing head 12 of approximately 300 mm, a mixing speed on the outer diameter of the mixing head of 4.27 m / sec.
  • this mixing speed the necessary friction is achieved, especially for the introduction of air pores; in the short period between the entry of the mixed material into the mixing head 12 until the discharge thereof, as already noted, at least a doubling of the air pore content is obtained.
  • additives e.g. B. fibers, light aggregates or premixed foam.
  • Insulating masonry mortar with expanded clay shows that the desired state in set form, a liter weight of less than 1.0, can be reliably achieved by using the mixing head, because the additional air pore content of 8 to 10% in any case Increased effect results, while when using conventional continuous mixers the required effect cannot always be achieved.
  • Insulation masonry mortar with an expanded clay aggregate - but also other masonry and plastering mortar - tend to be stiffened in the crane bucket or in subsequent transport containers. Otherwise, the post-stiffening effect must either be taken into account when mixing or the mortar must be mixed with water again before use. This post-stiffening effect is significantly reduced by using the mixing head 12 because the dwell time in the mixing head is longer and at least a part of the post-stiffening phase has already expired in the mixing head.
  • the mixing head according to the invention can - as explained in connection with the illustrated embodiment - be used as an additional device for existing continuous mixers; however, it can also be attached directly to the metering device in a mixing device - without the interposition of a mixing chamber. While the normal embodiment of continuous mixers of the type in question runs horizontally, it is possible, when using the mixing head according to the invention, also to incline primarily towards the discharge end see, but always make sure that a mix sump is obtained in sufficient depth. If the dust cover at z. B. by 10 ° inclined mixer shaft perpendicular to this mixer shaft, care must be taken that there is still enough mix in the sump, so that the lower region of the dust cover 1 & must be increased by a corresponding amount.
  • a baffle element in the form of a dust baffle or a correspondingly designed discharge opening is connected to the mixing chamber 8, which has an enlarged cross section in its rear region in the above-described exemplary embodiment.
  • the desired material jam in the mixing chamber 8 is due to the design of this chamber in the area of the carrying opening 17 causes.
  • the mixing chamber 8 has namely narrowing in this area before and during the discharge opening 1 7 in a conveying direction, in the exemplary embodiment the tapered longitudinal section, that is, their cross-section decreases towards the discharge opening 17 toward steadily.
  • the material conveyed to the discharge opening 17 is jammed by this constriction and, above all, the rise in the bottom area.
  • the discharge opening 17 can be correspondingly narrow.
  • an agitating tool 25 which is adapted with its outer edge 23 to the bevel of the taper 24, is also arranged in this area.
  • the material jammed in the taper 24 is therefore additionally mixed by the stirrer 25, so that a corresponding introduction of air pores can also be expected in this area.
  • the damming element serving to extend the dwell time of the material to be mixed is fastened to the shaft 5 carrying the mixing tools and rotates with it.
  • FIG. 4 and 5 show an embodiment in which conveying vanes 27 acting against the conveying direction are provided at the end of the mixing shaft 5 in the conveying direction.
  • 5 shows three evenly distributed conveying vanes 27 of this type, which according to FIG. 4 are arranged just before the discharge opening 17.
  • These blades 27, which operate in the opposite direction to the conveying vanes 28 located at the beginning of the mixing chamber 8, can have approximately the same conveying effect as the aforementioned vanes / 28 have, so that the material feed through the mixing chamber 8 through the pressure exerted by the dosing screw 7 in the conveying direction is carried out.
  • annular disk 29 is fastened to the shaft 5 as a baffle element, which has 8 openings or passage slots both in its interior 30 and on its outer edge 31 with respect to the mixing chamber housing.
  • a stirring tool 11 is connected directly to this ring 29, which increases the stability of the fastening of the ring disk 29.
  • Fig. 7 it can be seen that, for example, three webs 32 can carry the washer 29.
  • the mixing chambers 8 are each provided with a substantially constant cross-section over their entire length, so that they are e.g. B. od. The like. Can be made.
  • a mixing housing 8 that can be separated from the metering area, for example, this can be easily cleaned, especially if the baffle element remains on the shaft 5.
  • the respective filling volume in the mixing chamber during operation is more than 50%, preferably even more than 60 to 70%, of the respective inner volume of the mixing chamber 8.
  • the volume taken up by the shaft 5 and the stirring tools may have to be taken into account accordingly.
  • the filling volume should be less than 100% and preferably less than 90% of the total inner volume. It has been shown that a good loading and intensive introduction of air pores into the mixture is possible in this way.
  • the residence time of the mixture in the mixing chamber 8 is preferably more than 20 or 30 seconds and, particularly in the exemplary embodiment according to FIGS. 8 and 9, is expediently of the order of 40 or more seconds. In the other exemplary embodiments, too, a residence time is expedient which allows sufficient air pores to be stirred into the material. It is advantageous if the peripheral speed on the outer agitator diameter is 2 to 3 m per second and preferably about 2.5 m per second. Depending on the embodiment of the stirring tools, certain deviations from these values may be appropriate. If the peripheral speed is too slow or too fast, the result is less favorable.
  • the shaft 5 carries several baffle elements distributed over its length in the region of the mixing chamber 8, these baffle elements in each case being counter-wings or parts thereof. These are expediently connected to the stirring tools 11 in FIG. 1. It is conceivable, for. B., the ends of the stirring tools 11 in Fig. 1 or the stirring tools 11 of Fig. 4, 6 and 8 to be designed as blades acting partially counter to the conveying direction, so that there is a corresponding build-up of the stirred material and thus a correspondingly long dwell time.
  • Another possibility is to extend the mixing chamber of a device sufficiently to obtain a long residence time. It may then even be possible to dispense with baffle elements; in this case the large length of the housing wall, which generates a corresponding flow resistance, also acts as a backlog, that is to say as a kind of baffle element distributed over the length.
  • the dwell time is correspondingly increased again, so that an increased amount of air pores can again be introduced into the mixture, in particular with appropriate degrees of filling and peripheral speeds.
