Definitions

  • the invention relates to a device for mixing liquids with one another or mixtures of substances with different consistencies in a fixed, tubular housing attached to a pipeline with a circumferential shaft provided in the lower part with a continuous longitudinal bore, the angle of approximately 45 ° arranged to the axis of the pipeline, mounted in the housing and driven by a motor, the lower part of the shaft having a nozzle head protruding into the pipeline with a nozzle device which has a transverse bore arranged perpendicular to the continuous longitudinal bore and connected to it comprises, and wherein the liquid supplied through the longitudinal bore can be injected into the main liquid flowing in the pipeline.
  • DE-HB-10 66 544 describes a device for mixing liquids with one another or mixtures of substances with different consistencies in a fixed, tubular housing having a pipeline, with a shaft running around it and designed as a hollow shaft.
  • the shaft is arranged perpendicular to the axis of the pipeline, mounted in the housing and driven by a motor and has holes in its part in the pipeline that serve as nozzles.
  • the liquid supplied through the bores of the hollow shaft can be combined and mixed with the liquid flowing in the pipeline.
  • DE-HB-10 79 001 discloses a continuous mixer for mixing two or more components with a mechanically driven one arranged in the train of a pipeline Mixing and conveying device known.
  • the continuous mixer essentially has mixing chambers with mixing elements, the axial inlets of which for the respective additional component take place through feed lines which in turn lead for the additional component into the axial inlet of the mixing elements.
  • the mixing elements are driven by a shaft held in bearings, with a mixing pump, screw or propeller downstream of the mixing elements to increase the conveying effect of the material to be mixed.
  • DE-HA-15 57 129 describes a device for introducing one medium into another.
  • the device has a driven solid shaft with a hollow shaft arranged thereon, on which a number of vanes are provided, which generate a negative pressure when the hollow shaft rotates on its rear side, so that the medium located in the hollow shaft through the holes from it a pipe is sucked out with a flowing medium.
  • the required vacuum can be provided as long as the holes in the hollow shaft are open and the vanes arranged on the hollow shaft produce for the escape of the medium located in the hollow shaft through the holes in the medium in the conduit, a mixing process between two liquids can be easily effected, but the mixing is particularly problematic when highly viscous liquids are to be fed to another medium with this device, because As a rule, the holes in the hollow shaft clog up quickly and the blades can then no longer generate the necessary negative pressure.
  • this device is also not intended for such a purpose, especially since it is expressed in the publication that this device is particularly well suited for introducing a gas, for example air, into a liquid, for example water.
  • the device has a pipeline in which a circular disk provided with nozzle openings and taking up almost the entire cross section of the pipeline can be rotated by means of a hollow shaft, the hollow shaft extending through a stuffing box attached to the pipeline to a bearing and drive device for the shaft .
  • a passage with at least one opening in the hollow shaft the suspension obtained from a container is introduced through the hollow shaft into the circular disk with the nozzle openings, from where portions of the suspension enter the pipeline and can be swirled uniformly with the gaseous medium with low power consumption are.
  • DE-HA 30 45 383 describes a device for mixing a solution of concentrates, in particular water and liquid polymers, for tertiary oil production.
  • a dosing chamber is used for this purpose, in which flowing water and flowing concentrate are brought together and mixed.
  • the metering chamber is located in the central area of a tubular jacket with a lateral flange, through the bore of which water can be conducted to the metering chamber located inside the jacket.
  • a stamp with an internal thread can be inserted into the tubular jacket, a packing between the stamp and the jacket ensuring mutual sealing.
  • a liquid polymer can be conveyed to the metering chamber through a central channel provided inside the stamp.
  • At the upper end of the stamp there is a dosing head with a distribution chamber.
  • a compression spring provided in the distribution chamber presses a steel ball against an opening of the central channel, so that a backflow prevention valve is thereby formed.
  • the steel ball lifts up from its mouth so that the liquid polymer can flow into the distribution chamber, then distribute itself over supply channels and flow through these into an annular water channel within the metering chamber. Downstream from the dosing head, strong turbulent vortices form, in which the liquid polymer injected into the water in the water channel can again be swirled strongly with the water.
  • a mixing device is known from US-HA-3 920 225, in which the axis of a pipeline is designed to be inclined at 45 ° to that of a tubular housing, a shaft designed as a hollow shaft, motor-driven and projecting into the housing, having nozzles in a nozzle head is provided, through which the supplied liquid is injected into the liquid flowing in the pipeline.
  • the supplied liquid is conveyed axially into the hollow shaft via a hose or the like, which is set in rotation by a V-belt transmission. In this way, the problem arises that the liquid has to be conveyed from a fixed component into a rotating component, which is associated with considerable structural disadvantages or can be achieved by appropriate expenditure.
  • the invention is therefore based on the object of proposing a device for mixing liquids or mixtures of substances with different consistencies, with which even when a highly viscous liquid is mixed with another liquid, clogging of nozzles or channels is avoided and a uniform distribution of the liquid to be mixed is achieved should, so that a constant mixing quality can be achieved.
  • a nozzle head arranged on a hollow shaft rotating or oscillating in a pipeline is provided with a nozzle device which has a valve arrangement working as a nozzle, in which a highly viscous liquid is added even when admixed Clogging is no longer possible since the pressure of a metering pump then rises until the valve arrangement is open again.
  • the device according to the invention has a simple, robust and easy to maintain structure.
  • FIG. 1 An embodiment of the invention is shown in the drawing and is explained in more detail below.
  • the only figure in the drawing shows a section of a mixing device according to the invention with the nozzle head arranged on the hollow shaft and having a nozzle device with a valve arrangement.
  • the mixing device has a tubular housing 2 with a pipeline 1 arranged thereon, through which a main liquid flows, the axis of the pipeline 1 being inclined at an angle of approximately 45 ° to that of the tubular housing 2.
  • the tubular housing 2 has in the lower housing part 8b on the left side a cylindrical bore 3 through which a liquid to be mixed can be introduced into the lower housing part 8b of the tubular housing 2.
  • seals 28, 29 are provided on a cylindrical inner wall part 5 in the lower housing part 8b of the tubular housing 2, recesses 6 for seals 28, 29 are provided according to one embodiment of the invention, which are intended to prevent liquid or lubricant between the cylindrical inner wall part 5 of the lower housing part 8b and one more explanatory shaft 9 can leak.
