Definitions

  • the invention relates to a method for continuous Manufacture of pumpable, colored mortar compounds in one Mixer, the dry mortar and a metered water flow are fed and in the continuously liquid paint is metered in, and mixer to carry out the process.
  • the mixer essentially consists of one Mixing tube containing a mixing shaft with mixing blades and in the area of its one end the dry mortar and in its further course via a water supply line the water is fed.
  • a screw pump is arranged downstream of the mixing tube.
  • the DE 27 04 391 A1 shows a mixer that uses the method works from which the invention is based.
  • the well-known mixer is especially for the production of pumpable gypsum determines and comprises a mixing tube in the area of its upper end of dry matter and in the further course water is supplied laterally via a connecting piece, and a pump downstream of the mixing tube.
  • At the connector opens up a complex water supply device, that of a clear water supply circuit and a color water supply circuit exists in the clear water feed circuit flows so that clear water and color water are mixed and the mixture thus obtained flows into the mixing tube.
  • the color water supply circuit in turn includes upstream of the muzzle an electrically controllable valve, a flow circuit with a pump for color water from a container and a feedback loop.
  • the invention has for its object a method and a mixer for quick and inexpensive delivery to create usable colored mortar compounds.
  • this task is the one mentioned in the introduction Process solved in that the liquid paint on is metered in at a point where it is operational lower than atmospheric pressure.
  • the liquid paint is preferably metered into the water stream.
  • the resulting dilution before discharge in the mixer leads to a particularly even color the mortar mass produced.
  • the speed of the Water flow at at least one point to generate a static vacuum increases and at this point the liquid Color fed.
  • the height difference between the place where the liquid paint enters the water flow and the installation site of the Paint container affects the metered amount of paint. Therefore
  • a measure to increase the Speed of water flow can be dispensed with, namely then when the paint container is sufficiently high above the point the initiation of the color arranged in the water flow and at the same time it ensures that the of the container line leading to the discharge point, usually a Hose, at the beginning of the mixing process with liquid paint is filled as well as one to be operated when the mixer is at a standstill Shut-off valve contains.
  • a list of the Container so that its content is about liquid color located at the point of discharge is to save the Shut-off valve conceivable.
  • the paint can be added to the mixer screw pump be dosed.
  • the air inlet In the upstream part of the screw pump operationally there is a lower than atmospheric pressure.
  • Air entrainer pumps the air inlet. This air intake can be used to dose the liquid paint.
  • another inlet can be used at a suitable point be provided in the form of a bore. In this case it sucks the mixer screw pump both air and paint on.
  • the metering device can in particular be a liquid Color-sucking Venturi nozzle.
  • the metering device can be a liquid one Be a paint suction water jet pump.
  • the water supply has a cross-sectional narrowing on, with the liquid paint downstream of the cross-sectional constriction taking advantage of one of the water streams generated negative pressure metered directly into the water flow becomes.
  • the metering device can also be a liquid paint sucking, preferably electrically powered Be a pump.
  • This embodiment is more complex than the aforementioned self-priming embodiments, but especially when using a Dosing pump has the advantage that even more viscous, liquid Colors can be metered into the mixer. Moreover In this way, a particularly high dosing accuracy can be achieved and thus achieve color consistency, regardless of that Place of installation of the paint container as well as the length and the cross section the line supplying the paint.
  • the metering device is preferably a replaceable unit educated. Especially when the dosing device a Venturi nozzle or a water jet pump, it can as a short intermediate piece between the mixer-side water connection and that coming from the water metering device Line, usually a hose, be formed. In is usually the connection between the water hose and the mixer-side water connection designed as a quick coupling. Therefore, existing, conventional mixers can be used of almost any design can be carried out quickly and easily of the method according to the invention or in a mixer Convert to produce colored mortar compounds. Another The advantage of this embodiment is that a number of calibrated to different color throughput quantities Dosing devices kept ready and depending on the desired Tint or color intensity of the mortar mass produced can be used or replaced. This avoids a complicated mechanism of the dosing device and lengthy Adjustment work and test runs with different Dilutions of the liquid color of the chosen fundamental.
  • the liquid can be used to fine-tune the color Color leading supply line a valve for setting the Flow can be arranged.
  • the method and the Mixer according to the invention has the advantage that the metering the color takes place automatically when the mixer is in Operation is.
  • a dosing device in This can be done in the form of an electrically driven pump can be easily reached via the machine control.
  • the self-priming embodiments are no further measures are necessary because at standstill the machine used to dose the color Vacuum breaks down.
  • the self-priming Embodiments have the advantage that the metered amount of liquid paint automatically adapts to the respective volume flow of water, because the one prevailing at the dosing point Vacuum changes in the same direction as the Change in the respective volume flow.
  • a standing worker is an example Mixer for the production of spray plaster depicted this however only representative of others, also lying or mixers working at an angle e.g. for production of Self-leveling screed or masonry mortar.
  • the mixer comprises a mixing tube 1 with a mixing shaft 2 basically any training in the area of his top of a funnel 3 loaded with dry mortar becomes.
  • a mixing tube 1 with a mixing shaft 2 basically any training in the area of his top of a funnel 3 loaded with dry mortar becomes.
  • a conventional one Screw pump 4 flanged namely here in the embodiment as an air-entrained screw pump, whose screw casing 4.1. accordingly has an air connection 4.2.
  • the worm shaft 4.3 is via a dog clutch with the mixing shaft 2 connected and in turn drives the shaft on the output side 5.1 of a post-mixer 5, which is however optional.
  • the final mixer 5 goes to the finished mortar mixture Hose 6 transporting the place of use.
  • All shafts are driven by a common drive motor 17 driven with a downstream reduction gear.
  • a paint metering device 7 connected, which according to the well-known principle of the Venturi tube is working.
  • the Ink metering device 7 has a venturi nozzle Cross-sectional narrowing in which the bore of a connection 7.1 opens, to which a paint hose 9 is connected which is a symbolically illustrated pinch valve 10 sitting.
  • the hose 9 leads to an immersion tube 11 in one liquid paint containing container 12. At the bottom of the Dip tube 11 is a check valve 13.
  • FIG. 1a An equivalent ink metering device 14 is shown in Fig. 1a shown. It works according to the well-known principle of Water jet pump.
  • the screw pump 4 can also the screw pump 4 as a metering device to be used.
  • the water hose 8 is direct connected to port 1.3 while the paint hose 9, as shown in dash-dotted lines, over a suitable one Intermediate piece (not shown) to the hole 4.2 is connected in the screw shell 4.1.
  • the Paint metering device 7 or 14 flowing water stream at the port 7.1 one of the flow rate of the Water at the narrowest point of the paint metering device Negative pressure generated. This will over the paint hose 9 sucked liquid paint from the container 12.
  • the Color flow i.e. the amount of color metered in per time unit depends on the water flow in the water hose 8, i.e. the set amount of water per unit of time, from.
  • the color flow can be adjusted of the pinch valve 10 are changed.
  • liquid paint is not in the mixing water flow but is metered into the screw pump 4, basically the same applies. However, it is recommended then for a more even distribution of the color in the mortar the use of the drawn post-mixer 5.
