Definitions

  • the invention relates to a compulsory mixer for mixing liquid, powdery and / or granular components, such as concrete mixtures, and the use of air inlets, in particular for cleaning such a forced mixer.
  • a compulsory mixer of the type mentioned is for example from the DE 1 116 195 B or the EP 1 121 193 B1 known.
  • the mixers described in these publications each have a mixing container, along the central axis of which an internal agitator is mounted, which is in the form of a screw.
  • an external agitator is still present, which performs an edge-side mixing of the material to be mixed and can be in contact with walls of the mixing container or can reach near the walls.
  • a compulsory mixer for mixing components comprises a mixing vessel, wherein an agitator is formed along an axis of the mixing vessel, comprising a shaft with mixing blades attached thereto, wherein at least one air inlet, preferably several air inlets, e.g. Air nozzles are coupled to the shaft, which are designed for feeding air into the mixing container.
  • mixing blade as used in the context of the invention, it is intended to include any type of mixing tool which is suitable for imparting a relative movement to the components to be mixed.
  • the special shape of the mixing blades is not decisive here.
  • mixing blades can be used in blade form, as helixes or in the form of coulters.
  • the shaft of the agitator fulfills two functions: Firstly, the material present in the mixing container is mixed when the shaft of the mixing container rotates about its own axis, as is usual in such mixers, wherein they also mix the mixing blades Rotational movement are entrained around this axis.
  • air can be introduced into the mixing vessel or into the material to be mixed via the shaft through air inlets provided therefor.
  • the air supply is preferably controllable by the user regardless of the rotational movement of the shaft.
  • the time and duration of the connection of the Lucaseinspeisevorraum can be selected by the user depending on the need for cleaning.
  • air is introduced into the mixing tank filled with water.
  • the resulting air bubbles cause, depending on their size and amount turbulence and turbulence of the water and the aggregates, resulting in particular along the inside of the housing and the agitator to higher flow velocities, which impurities are "entrained".
  • the internal agitator can run forward and backward during cleaning, resulting in a further improvement of the cleaning effect.
  • the air feed can also take place when the mixing container is filled with a mixed material.
  • a mixed material For example, when producing lightweight concrete, it is possible to introduce any amount of air into the material to be mixed.
  • the shaft is designed as a hollow shaft, wherein the Heileinspeisevortechnik is provided inside the hollow shaft.
  • the Lufteinspeisevorectomy has the advantage that the Heileinspeisevorectomy claimed in addition to the necessary for mixing components of the agitator no additional space in the interior of the mixing container.
  • the connection of the Heileinspeisevortechnik outward can be realized in this embodiment, for example by means of a rotary feedthrough.
  • the air inlets are preferably provided at the lower end of the shaft. But they can also extend along the entire height or portions of the shaft. It is particularly advantageous if the air inlets a so-called Ausströmerstein is connected upstream. Depending on the nature and condition of the Ausströmersteins the bubble size can be varied accordingly and thus a homogeneous mixing can be achieved.
  • the air inlets prefferably be arranged exclusively or additionally along the inside of the housing jacket in order to feed air from outside into the mixing container.
  • the air feed device has a control device, wherein the air flow rate is adjustable by a user.
  • the air flow rate is adjustable by a user.
  • the control device it can be integrated into the controller for the mixed operation of the forced mixer.
  • the controller is designed so that the air feed device is driven in the interval mode. That is, when a drive mode for the interval operation is selected by the user, the air supply device turns on and off after a predetermined time interval, respectively.
  • This activation mode can be particularly advantageous in optimizing the cleaning or mixing process.
  • the air supply via the air supply line can be done for example by means of an electric air pump.
  • the compulsory mixer can be, for example, a so-called “cone mixer", in which the mixing container is funnel-shaped or cone-shaped.
  • the compulsory mixer may comprise, in addition to an internal stirrer, which may be in the form of a screw, for example, a further agitator having mixing blades which are drivable for rotational movement along an inner wall of the funnel-shaped mixing container.
  • the additional or external agitator causes an additional mixing of the mixed material, whereby the mixing container is optimally utilized.
  • the invention further relates to the use of air intakes for feeding air into such a forced mixer.
  • FIG. 1 an embodiment of a compulsory mixer according to the invention in cross section.
  • FIG. 1 shown compulsory mixer is indicated in its entirety by the reference numeral 10. It comprises a mixing container 1, which, as can be seen in the figure, is formed at least in its lower part with a conical or funnel-shaped housing 1a.
  • the shape of the mixing container However, in the context of the present invention, FIG. 1 is not to be regarded as limiting.
  • the agitator 2, 3 comprises an internal agitator 2, which is constructed from a shaft 2a and mixing blades 2b mounted thereon, wherein the mixing blades 2b are here arranged helically on the shaft 2a.
  • the shaft 2a extends along an axis A of the mixing container 1, wherein the axis A is indicated in the figure by a dashed line.
  • the outer agitator 3 comprises a shaft 3a, which is here arranged concentrically to the shaft 2a, with mixing arms 3b attached thereto, which are provided at their ends with mixing blades 3c.
  • the mixing blades 3c stroke along the inside of the housing 1a of the mixing container 1. It should be noted that the presence of the outer agitator 3 in the context of the present invention is not mandatory.
  • the embodiment according to the invention has air inlets 4b, which are formed here at the lower end of the shaft 2a.
  • the air supply line 4 a is inserted into the interior of the shaft 2 a according to this embodiment, so that it does not claim any additional space in the interior of the mixing container 1.
  • additional air inlets are provided in the form of nozzles on the housing 1a.
  • the air feed device 4 comprises an air feed line 4a and the air inlets 4b connected to the air feed line.
  • the air supply line 4a is guided in the interior of the shaft 2a down.
  • the air supply line 4a is connected via a rotary feedthrough 5 to the outside, wherein the rotary feedthrough 5 simultaneously seals the interior of the shaft 2a to the outside.
  • the air supply can be done by an electric air pump (not shown in the figure) via the air supply line 4a.
  • the cleaning water or mixed material air is supplied in the form of air bubbles in the desired amount and the compulsory mixer 10 can also be cleaned with little effort, or can be easily manufactured lightweight concrete.
  • the connection of the air feed device 4 can be carried out both during the mixing process, when the mixing blades 2 b driven by the shaft 2 a perform a rotational movement, as well as at standstill of the forced mixer 10.
