Definitions

  • the invention relates to a method for the continuous preparation of mortar, plaster, concrete or the like.
  • Building material or material in which the material is fed to a metering device and then mixed with liquid. is mixed at the same time and fed to a discharge opening, the mixture being stowed in the area of the water supply and / or in the conveying direction behind it and being stirred in the meantime, while a quantity of material exceeding the stowed quantity emerges from the mixing area and the discharge opening.
  • the invention further relates to a device for the continuous preparation of mortar, plaster, concrete or the like.
  • a discharge opening is arranged at the end of the mixing chamber.
  • the mixing chamber opens into a discharge opening without a jam protruding from below, which is only partially closed from above by a bearing bracket.
  • a material jam is only possible if more material accumulates than the discharge opening directly from the floor can release. If a jam occurred, there was again the disadvantage that dead spaces were formed in the area of the jammed wall.
  • the solution to this problem is that the material which has been brought into contact with water is subjected to counter-conveyance from the outlet from the mixing zone which is less than the conveyance in the conveying direction.
  • This counter-promotion causes: in the desired manner, a restraint of the material without completely preventing its escape and without leading to a jam of part of the material in a dead space.
  • an additional mixing effect with additional introduction of air pores can be generated by such counter-promotion.
  • the mixing chamber has more than 50%, preferably more than 60% to 70% of its internal volume during operation, in particular after deducting the volume taken up by the agitator shaft, but with less than 100%. preferably less than 90% is filled.
  • the residence time of the mixture in the mixing chamber can be selected to be longer than 15 to 20 or 30 seconds, preferably 40 to 60 seconds, and the circumferential speed at the outer agitator diameter can be approximately 2 to 3 meters per second, preferably approximately 2.5 meters per second.
  • the invention also includes a device for the continuous preparation of mortar, plaster, concrete or the like material, as is known from FR-A-2 382 992.
  • a device for the continuous preparation of mortar, plaster, concrete or the like material as is known from FR-A-2 382 992.
  • the device is said to be particularly suitable for carrying out the method according to the invention and is characterized in order to achieve the stated object in that the mixing chamber in the area in front of and / or at the discharge opening in the conveying direction has a conically narrowing longitudinal section such that a counter-conveying of part of the material is achievable.
  • 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.
  • a baffle element, a disk, a ring or the like can be attached to the shaft, which has passages on the inside and / or on the outside opposite the housing of the mixing chamber openings or the like.
  • the damming element fastened to the shaft can carry projections, wings, blades or the like. Additional mixing devices, 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, because of its rotation, additionally as a mixing and Stirring tool is used.
  • the counter-acting conveying vanes or blades can have approximately the same conveying effect as the conveying vanes or vanes provided overall in the mixing area, so that the material feed is brought about 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 at the circumference of the shaft and at the end the baffle element, in particular the vanes acting against the conveying direction, as well as conveying-neutral mixing or stirring tools are arranged in between at the beginning of the mixing chamber .
  • the material is mainly stirred through most of the mixing chamber and a corresponding amount of air can be mixed in.
  • a further advantageous embodiment is given in expression 13.
  • a considerable advantage of the rotating dam elements is that the mixing chamber can have a substantially constant cross section over its entire length, tapering only at the end, so that enlargements of the chamber or the like make production difficult or a trough with a rising bottom or the like can be avoided.
  • a device for making mortar for example placed on a running gear, has an inlet and a connecting piece 2. The latter leads to a horizontally running loosening space 3.
  • An electric motor 4 is connected to one side of this loosening space 3, 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 dosing device, which has a water addition 9 and is detachably flanged to the tubular part forming the loosening space 3 and the dosing space.
  • the shaft 5 also extends straight into the mixing chamber 8.
  • the mixing tools 11 can be conventional mixing paddles, some of which provide for mixing and some of which promote the mixing material.
  • the discharge opening 17 of the mixing chamber 8 is substantially smaller than the diameter thereof.
  • the discharge opening 17 can be arranged asymmetrically.
  • the inlet with the connection piece 2 can be provided below a silo and the device according to the invention for mixing mortar can be connected to this silo in a fixed or detachable manner.
  • the material that has been mixed with water is subjected to counter-conveyance, which will be described below, which is less than the conveyance in the conveying direction in order to expose the mixed material to a longer residence time in the mixing chamber 8 and thus the number of air pores within one To increase the mix.
  • the desired counter-promotion of the mixing chamber 8 is brought about by the design through this chamber 8 in the region of the discharge opening 17.
  • the mixing chamber 8 has namely in this area in front of and at the discharge opening 17 in the conveying direction such a narrowing, in the exemplary embodiment tapering longitudinal section that counter-conveyance of a part of the material can be achieved.
  • the cross section decreases steadily towards the discharge opening 17.
  • the discharge opening 17 can be correspondingly narrow.
  • the counter-conveying 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.
  • the shaft 5 is fastened to an annular disk 29, which has 8 openings or through-slits both in its interior 30 and on its outer edge 31 with respect to the mixing chamber housing.
  • An agitator 11 is connected directly to this ring 29, which increases the stability of the fastening of the ring disks 29. 4 mi thereby that, for example, three webs 32 can support the washer 29.
  • both in the embodiment of FIGS. 1 and 2 and in that of FIGS. 3 and 4 are at the beginning of the mixing chamber 8 a row of conveying vanes 28 located on the circumference of the shaft 5 and at the end the counter-conveying element and in between the conveying-neutral mixing or Stirring tool 11 arranged.
  • this space in particular is practically fully utilized as storage space, in which these stirring tools 11 can introduce as much air as possible into the material mixed with water at the same time.
  • the mixing and stirring tools 11 are designed as grids in order in turn to intensify the introduction of air.
  • the mixing chambers 8 are each provided with essentially the same cross-section over their entire length, so that they can be manufactured, for example, from a tube or the like. In addition, this makes it easy to clean a mixing chamber 8, which can be separated from the metering area, for example, it being advantageous that the counter-conveying element remains on the shaft 5.
  • the respective filling volume in the mixing chamber 8 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 occupied by the shaft 5 and the stirring tools 11 may need 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. 5 and 6, 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-vanes or parts thereof. These are expediently connected to the stirring tools 11 in FIG. 1. It is conceivable, for example, to design the ends of the stirring tools 11 in FIGS. 1 or 3 and 5 as blades which act partially counter to the conveying direction, so that there is a corresponding build-up of the stirred material and therefore a correspondingly long dwell time.
