Definitions

  • the invention relates to a mixer, in particular a movable mixer, for mixing at least two solids with a liquid to obtain a flowable, preferably pumpable mixture, in particular a concrete mortar, with a mixing and conveying screw, which preferably rotates concentrically in a jacket, with a solids input, mixing - And conveying section with a solids supply arranged above it and then a liquid supply, mixing and conveying section is provided, in which the jacket has at least one liquid passage for introducing liquid into the jacket interior.
  • the mixer according to the invention is characterized above all in that the solids supply has in each case one feed funnel with an independently controlled metering device per solids.
  • the metering device for coarse-grained solid is a cellular wheel lock or the like. and the fine grain solid dosing device is a screw conveyor.
  • the feed for coarse-grained solid is arranged in the conveying direction before the feed for fine-grained solid.
  • a common chute for the solids is provided between the metering devices and the solids introduction section.
  • a conveying direction rising to the horizontal is provided, the angle of rise preferably being approximately 20 °.
  • the mixer according to the invention is primarily intended for the production of concrete mortar, in particular lightweight concrete mortar, for example polystyrene lightweight concrete mortar, but can also be used for other purposes.
  • FIG. 1 is a schematic side view
  • FIG. 2 is a plan view of a movable mixer.
  • a screw conveyor is arranged, in which a screw conveyor 4 driven by a drive control motor 3 rotates in a jacket, which has a smaller diameter solids entry, mixing and conveying section 5a, in which the added solids are mixed and conveyed without the addition of liquid, and has an adjoining liquid supply, mixing and conveying section 5b of larger diameter, in which mixing liquid is metered in and mixed in from outside the jacket and which is provided at its end with a discharge nozzle 6 , through which the finished mixture is dispensed.
  • the feed hopper 7 adjacent to the drive motor 3 serves to feed coarse-grained solids, e.g. Aggregates, and the feed hopper 8 for the feeding of fine-grained solids, e.g. Cement.
  • the feed hopper 7 has a metering rotary valve 10 which is driven by a control motor 11, while the feed hopper 8 has a metering feed screw 12 which is driven by a control motor 13.
  • Motors 3.11 and 13 are e.g. usual, continuously variable geared motors.
  • the dry or naturally moist solids are mixed and conveyed together into the jacket section 5b, where liquid is metered in with continued mixing, so that a homogeneous solids / liquid mixture is dispensed at the dispensing nozzle.
  • the continuous metering of liquid takes place in a known manner via flow controllers depending on the desired mixing ratio.
  • a liquid metering nozzle 14 is shown.
  • the drive or the metering devices are controlled in Usually via a simple process computer on which the delivery rate or the mixing ratios can be set.
