Definitions

  • the invention relates to a method for mixing mixtures with rheological properties, and a mixer for carrying out the method.
  • Solid, liquid and gaseous components are mixed with mixers.
  • a gaseous component is almost always to be understood as air.
  • Mixtures with rheological properties i.e. elastic-plastic-viscous properties, have a structure that resists mixing.
  • the greater the resistance of the structure the harder the mixing and the worse the mixing.
  • the resistance of the structure represents the basic problem of the known mixers for the energy and effect of the mixing as well as for the durability and the service life of the parts of the mixer.
  • Such mixers are therefore only suitable for mixtures with low structural resistances.
  • This fundamental disadvantage of gravitational mixing is avoided when using so-called compulsory mixers, which normally have a stationary housing and movable blades.
  • the paddles of a compulsory mixer are driven by a vertical or horizontal shaft, the mixing components being moved and mixed by planetary motion.
  • the structural and contact resistance of the mix is the main limiting factor for these mixers.
  • the limiting factor of mixing and coboiditation is particularly apparent due to the structural and contact resistance of the mixture.
  • the contact and internal resistances of the mixture represent a special functional problem and a limiting effect factor.
  • the object of the invention is to provide a mixer of simple construction which substantially reduces the structural and contact resistances of mixtures of rheological properties during mixing.
  • the contact and internal resistances of the elastic-plastic and viscous mixture are reduced by the vibration effect of the vibrator.
  • a vibrator according to European Patent No. 238 688 is preferably used as the vibrator.
  • the mixer according to the invention can be used simply and effectively for mixing concrete.
  • high-frequency vibrators with adjustable frequency in particular vibrators as described in European Patent No. 238 688, can be attached to the underside of the base segments of a compulsory plate mixer by means of welding, screw connection or other fastening means.
  • These vibrators are particularly suitable, functionally reliable and easily connectable to a compressed air source, they do not require a return line and enable simple regulation of the compressed air throughput and the vibration frequency.
  • the vibration frequency can be matched to the speed of rotation of the measuring mixer in such a way that it is brought into harmony with the self-oscillations of the parts of the mixer and / or the mixture, which results in resonance Working conditions of great impact can be achieved with the lowest energy consumption.
  • the resonant mode of operation exerts a strong influence on the cement mass, i.e. on its dispersity, whereby the lowering of the consistency results in a better mixing and a more favorable and perfect distribution of the water compared to the cement grains, i.e. conditions are set which lead to a better one Concrete mix with a low water and cement factor, better workability and effective curing.
  • the invention can be used in the broadest possible way, for example for the production of building materials, paints or chemical mixtures.
  • FIG. 1 shows a section through a mixer according to a first embodiment
  • FIG. 2 to 4 a plan view of a mixer according to another embodiment.
  • a plate mixer has a cylindrical casing 1.1, a cylindrical inner wall 1.2 and a flat bottom 1.3, which delimit a cylindrical mixing space.
  • the cylindrical casing 1.1, the cylindrical inner wall 1.2 and the bottom 1.3 represent the stationary housing of the mixer.
  • Rotating blades 2.2 are provided in the mixer and are driven by a vertical shaft 2.1 in order to mix the concrete.
  • a compulsory mixer has a stationary housing 1, in which the mixing takes place by means of rotating blades 2.2.
  • the Blades 2.2 are driven by the horizontal shaft 2.1, the vibrator 3, which causes the vibration effect, being fastened to the outside of the housing.
  • the mixer according to FIG. 3 likewise has a stationary housing 1, in which the mixing takes place by means of rotating blades 2.2, which are driven by the shaft 2.1.
  • the vibrator 3 which causes the vibration effect, is attached to the blade arm.
  • the vibrator 3 is connected by means of a line L via a rotating connection, the axis of which coincides with the blade drive shaft 2.1, to a drive or energy source through which the vibrator 3 is driven, i.e. the line L can be, for example, a pressure or electrical line.
  • the mixer has a housing 1 rotating about an axis C, in which the mixing takes place by gravitational action and blades 2.2.
  • the vibrator 3 which causes the vibration effect, is attached to the inside of the housing 1. It is connected to the drive or energy source by means of a line L, for example a pressure or electrical line, similar to FIG. 3.
