Definitions

  • the invention relates to a device for producing bituminous mixtures for use in road or hydraulic engineering.
  • asphalt mixing devices which mainly contain a drying drum with dedusting, a metering device for the various minerals and bitumen, and a mixing device for preparing the mixture. Most of these mixing devices are also provided with the necessary storage devices for the storage of minerals, bitumen and the finished product.
  • the minerals are dried in the drying drum and heated to the desired temperature. In most cases, the mineral has to be heated to approx. 250 ° C.
  • a burner which is heated with gas or gas oil, is used as a heat source in the drying drum. Large amounts of air have to be added for combustion so that the extracted dust is filtered out. For environmental reasons, the requirements for this dedusting have become increasingly strict in recent decades. Most systems are therefore equipped with so-called cloth filters or wet filter systems to filter out the dust.
  • drum mixers which consist of a rotating drum.
  • the mineral is heated and dried in this drum as well as the mineral and bitumen are mixed.
  • This type of mixing device is also provided with suction and dust removal.
  • a disadvantage of the drum mixer is that overfilled mixtures cannot be produced or can only be produced with certain limitations.
  • old asphalt is possible with some limitations in both types of these known plants.
  • the addition can be up to 25%. With the drum mixer, this ratio is approx. 50%.
  • a device for transporting and dosing materials is known, the material being pressed through a housing by means of an axis provided with mixing and kneading blades, rotatable within the housing and movable to and fro.
  • the housing is provided with a heating or cooling jacket and the axis can be designed as a hollow axis through which a pipe is guided for the supply of a heating or cooling medium to the hollow mixing and kneading blades, for heating or cooling these blades.
  • the invention intends to provide a device which does not require extraction or dedusting and in which a complete use of old asphalt is possible. Tests have shown that the energy consumption is considerably cheaper than in the known mixing devices.
  • the device according to the invention is provided with a medium-heated cylindrical rotor, which can be rotated concentrically within an outer shell, which is located at a short distance from the rotor, and which is also heated by a medium, the material to be mixed and heated is in the gap-shaped space between the rotor and the outer casing, and in the outer casing there are one or more openings which are used to discharge gases, such as, for. B. steam.
  • the ingredients for the mixtures such as. As bitumen, minerals, broken old asphalt, natural or synthetic rubber, plastics, aggregates, such as. B. Fillers and ground rubber from old car tires are metered into a feed opening on one side of the device and the mixture formed is discharged from a discharge opening, which is preferably located on the other side of the device.
  • the rotor is preferably on the outside with projections, such as. B. cam pins and / or ribs provided.
  • the figure of the drawing shows a combination of a longitudinal section and a side view of a mixing device according to the invention.
  • the device consists of a preferably removable cylindrical outer shell 1, which is double-walled and by a heating medium, for.
  • a heating unit 2 As oil, is heated, which is brought to the desired temperature by a heating unit 2.
  • a cylindrical rotor 3 which is internally filled with heating oil, is concentrically located in the outer jacket. The heating oil in the outer jacket and in the rotor circulates through the heating unit and is kept at the desired temperature by this.
  • a circulation pump 4 can be provided.
  • the rotor which is set into a slow rotary movement by means of a drive motor 5, can be a smooth cylindrical body, a cylindrical body with a ribbed wall, or preferably provided with cams, pins or ribs 6 for transporting the material.
  • a funnel 8 is attached to the upper side of one end of the device and serves to load the mixing device. At the other end there is an outlet 9 through which the finished product can be derived.
  • the jacket On its upper side, the jacket is provided with openings 10 through which water vapor can escape.
  • the entire mixing device can be provided with insulation 11 in order to reduce heat losses.
  • the device is ideal for overfilled mixtures. However, it has been shown that even underfilled mixtures can be produced excellently.
