Definitions

  • the invention relates to a mixing device, in particular for bituminous mixtures, mixtures which are produced with this mixing device and building structures, in particular hydraulic structures which are made with these mixtures.
  • 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.
  • the minerals are dried in the drying drum and heated to the desired temperature. In most cases, the mineral must be erumblermt- to approximately 250 0 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 must be added for combustion.
  • drum mixers which consist of a rotating drum. In that drum the mineral is heated and dried, and 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%.
  • the invention relates to a mixing device which does not require suction or dust removal 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 mixing device is provided with a medium heated rotor, which can be rotated concentrically within an outer casing, which is located at a short distance from the rotor, and which is also heated by a medium, the material to be mixed being in the gap-shaped space between the rotor and the outer jacket.
  • the invention also relates to a process for the preparation of mixtures, in particular bituminous mixtures, whether or not using old asphalt and whether or not with additions such as e.g. Rubber or plastics, the mixing device being used, and mixtures which are produced by the method and building structures, in particular hydraulic structures which are produced using these mixtures.
  • the ingredients for these mixtures e.g. Bitumen, minerals, broken old asphalt, natural or synthetic rubber, plastics, aggregates such as 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 on the other side of the device.
  • the rotor is preferably a cylinder which is provided on the outside with projections, e.g. Cam pins and / or ribs for transport and / or the mixing of the material to be mixed is provided.
  • the outer jacket there are preferably one or more openings for discharging gases, such as e.g. Steam.
  • gases such as e.g. Steam.
  • the outer jacket can be double-walled and is preferably removable, e.g. hinged in the longitudinal direction.
  • 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 jacket 1, which is double-walled and is heated by a heating medium e.g. Oil is heated, which is brought to the desired temperature by a heating unit 2.
  • a heating medium e.g. Oil is heated
  • 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 rotational 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.
  • the invention also relates to a process for the preparation of mixtures, in particular bituminous mixtures, whether or not with the use of old asphalt and, whether or not with additions such as rubber or plastics, the mixing device being used, and mixtures which are produced by the process and building structures, especially hydraulic structures, which are made with these mixtures.
  • the ingredients for these mixtures e.g. Bitumen, minerals, broken old asphalt, natural or synthetic rubber, plastics, aggregates such as 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 on the other side of the device.
  • the rotor is preferably a cylinder which is provided on the outside with projections, e.g. Cam pins and / or ribs for transport and / or the mixing of the material to be mixed is provided.
  • the outer jacket there are preferably one or more openings for discharging gases, such as e.g. Steam.
  • gases such as e.g. Steam.
  • the outer jacket can be double-walled and is preferably removable, e.g. hinged in the longitudinal direction.
  • 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 jacket 1, which is double-walled and is heated by a heating medium e.g. Oil is heated, which is brought to the desired temperature by a heating unit 2.
  • a heating medium e.g. Oil is heated
  • 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 rotational movement by means of a drive motor 5, can be a smooth cylindrical body, a cylindrical body with a ribbed wall or, preferably, with cams, pins or ribs 6 for transporting the material. Between the concentric rotor and the outer jacket is a gap 7, in which the ingredients for the bituminous material are.
  • the distance between the outer casing and the rotor is preferably made as small as possible so that the heating of the material is supported.
  • 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.
