Definitions

  • the invention relates to a stirring body for a device for stirring fluids, in particular highly viscous fluids, and a device for stirring fluids.
  • DE 3901894 C2 discloses a device for stirring a flowable medium which has a container, a shaft arranged in the container and four stirring bodies which are fastened to the shaft.
  • the stirring bodies are tubular, open on both star sides and conical in the longitudinal direction.
  • the stirring bodies are fastened to support arms in such a way that they are inclined with respect to a plane of the support arms.
  • the agitators should be suitable for homogenizing highly sensitive substance pairings with little effort and in a short time, with great turbulence to be avoided.
  • the invention is therefore based on the object of providing a stirring body which, based on a tubular shape, brings about improved mixing of the fluid laterally from and behind the stirring body.
  • the stirring body mentioned at the outset is characterized in that the stirring body has an outer wall and a bottom at one end of the outer wall, which has at least one opening.
  • This stirring body has essentially a cup shape and at least one opening in the bottom.
  • a partial flow of the fluid is detected through the outer wall, and this flow strikes the floor, where it has to deflect laterally in order to be able to flow through the opening.
  • the changes in direction of the fluid during this process cause the fluid to be swirled laterally from and behind the stirring body, which advantageously provides the desired effect.
  • An advantageous embodiment of the stirring body according to the invention is characterized in that the at least one opening is arranged eccentrically with respect to the bottom. The eccentric arrangement of the opening in the bottom ensures that an asymmetrical flow occurs in the area of the bottom of the stirring body and exits through the opening, which increases the turbulence.
  • An advantageous embodiment of the stirring body according to the invention is characterized in that three openings are provided in the bottom, which are arranged at equal intervals around the center of the bottom.
  • the degree of the vortex can be controlled laterally from and behind the stirring body. The larger the openings and the more symmetrical they are arranged, the less the ner vortex.
  • the present embodiment of the stirring body is therefore suitable for fluids that are more sensitive than the fluids that are to be mixed by the stirring bodies claimed above.
  • the stirring body mentioned at the outset for a device for stirring fluids, in particular highly viscous fluids characterized in that the stirring body has an outer wall and a closed bottom at one end of the outer wall, and that at least one opening is provided in the outer wall , Since the bottom of the outer wall is closed and the opening lies laterally in the outer wall, the partial flow entering the stirring body will flow out laterally from the stirring body and provide the desired ner vortexing there.
  • An advantageous embodiment of the stirring body according to the invention is characterized in that the at least one opening has a diameter of less than half the height of the outer wall and is arranged close to the bottom of the stirring body.
  • the flow rate of the fluid flowing through the opening can be controlled by the size and position of the opening in the outer wall, and by the position of the opening close to the bottom of the stirring body, flow guidance is achieved which leads to the desired ner vortex.
  • an advantageous embodiment of the stirring body according to the invention is characterized in that three openings are provided in the outer wall, which are arranged at equal distances around the outer wall. As a result, the vortex is achieved substantially uniformly around the end of the stirring body, which is close to the bottom.
  • the stirring body mentioned at the outset for a device for stirring fluids, in particular highly viscous fluids is characterized in that the stirring body has a cylindrical or truncated cone-shaped outer wall and a conical body, the cone tip of which is directed towards one end of the outer wall and the latter Cone base is at the other end of the outer wall, and that the cone base of the cone body forms an annular opening with the outer wall.
  • An advantageous embodiment of the stirring body according to the invention is characterized in that the conical body extends only over part of the outer wall to the other part of the outer wall. As a result, the partial flow received by the stirring body is accelerated uniformly over the entire length of the outer wall, so that the entire height of the stirring body is used for conditioning the partial flow.
  • An advantageous embodiment of the stirring body according to the invention is characterized in that the outer wall has a circular cross section. This ensures that the parts of the fluid are gripped by the outer wall, but only at the bottom of the agitator body undergoes a turbulence.
  • a non-circular cross-section, for example a rectangular cross-section, would result in the flow at the corners of the rectangle experiencing an additional turbulence.
  • An advantageous embodiment of the stirring body according to the invention is characterized in that the outer wall is frustoconical.
  • Such a stirring body is arranged in use so that the end of the outer wall with the larger cross section lies in the direction of movement of the stirring body at the front. This results in an acceleration of the fluid from the front end to the rear end in the stirring body, which leads to an increase in the turbulence in the desired areas.
  • a device for stirring fluids in particular highly viscous fluids, is provided, in which the agitator body is supported on a support arm
  • Shaft are arranged such that their central axes are substantially tangential to a circle around the shaft, characterized in that the north direction of the stirring body according to one of the previous claims.
  • An advantageous embodiment of the stirring body according to the invention is characterized in that at least two, preferably four, stirring bodies are provided, as a result of which the action of force from the stirring bodies on the shaft is essentially balanced.
  • An advantageous embodiment of the stirring body according to the invention is characterized in that the stirring bodies are arranged on the support arms with a longitudinal axis inclined to the plane of movement of the support arms. As a result, the flows which leave the stirring bodies are deflected either upwards or downwards, so that an additional component results when the fluid is mixed.
