Definitions

  • the invention relates to a pressure-resistant mixer with a filling opening, a rotatable mixing container having an emptying device, with mixing tools inside the mixing container and with drive motors and drive means for driving the mixing tools and / or the mixing container, a stationary pressure container being arranged around the mixing container.
  • a disadvantage of these machines is that the seals between the pressure vessel, which simultaneously forms the mixing vessel, and the projecting mixing tool shafts lie in the area exposed to the mixture. These seals are therefore subject to heavy wear, contamination and chemical attacks. This often leads to extensive maintenance work in the area of the seals with correspondingly long machine downtimes.
  • a kneader is known in which a mix container is surrounded on three sides by a pressure vessel. However, the two end faces and the upper side are mixing vessel and pressure vessel walls at the same time.
  • pressurized seals of the tool bearings are all in the mix area.
  • a number of mixing tasks can be solved particularly well with so-called intensive mixers, which have a mixing plate (mixing container) rotating about a vertical or slightly inclined axis with mixing tools arranged eccentrically therein.
  • intensive mixers which have a mixing plate (mixing container) rotating about a vertical or slightly inclined axis with mixing tools arranged eccentrically therein.
  • Such machines have proven themselves particularly when mixing difficult-flowing, pasty and plastic masses. So far it has not been possible to do this to design a particularly effective mixing system for pressure or vacuum operation, since the slide seals required would be extremely large and, moreover, would have been exposed to harmful mix influences.
  • the technical problem to be solved for the present invention is to produce a pressure-resistant mixer, the pressure-resistant sliding seals of which, on the one hand, are not exposed to the mix and which, on the other hand, can work according to the principle of the intensive mixer even without the use of extremely large pressure-resistant sliding seals nevertheless has a simple, direct removal option for the finished mix.
  • the mixing tools are arranged eccentrically to the axis of the mixing container in the interior of the mixing container, that there is a passage opening at the bottom of the pressure container concentric with the axis of the mixing container and an emptying opening at the bottom of the mixing container, which opening is provided by an outlet ring attached to the edge of the emptying opening is formed, which is connected on its outside via a sliding seal to a sealing edge running concentrically through the passage opening at the bottom of the pressure vessel and that at the end of the pressure vessel over the wall of the mixing container and / or at the upper edge thereof, a sliding seal that is sealed against the mix is attached.
  • This separation of the pressure tank and the mixing tank allows the installation of sliding seals in areas that do not come into contact with the mix. It is also possible to arrange an intensive mixer in the interior of a pressure vessel, the size of the sliding seals to be used not being determined by the eccentric arrangement of the mixing tools, but only by the diameter of the drive shaft for mixing tools and mixing vessel and by the diameter of an emptying opening .
  • a passage opening is expediently provided concentrically with this emptying opening in the bottom of the pressure container below.
  • This passage opening serves on the one hand for the passage of the closure lid of the discharge opening and on the other hand also for the passage of the mixed material flowing out or falling out of the discharge opening.
  • Passage and emptying opening are connected to each other by an outlet ring, the upper edge of which is expediently tightly and firmly connected to the edge of the emptying opening and the lower edge of which is connected to the sealing edge of the passage opening of the pressure vessel via an external sliding seal.
  • the passage opening is thus formed by the lower inner region of the outlet ring.
  • This arrangement of the opening has the advantage that the sliding seal between the outlet ring and the sealing edge can have a minimal diameter, which means that the user can, if necessary, fall back on relatively inexpensive seals with standard dimensions, which are available from relevant specialist dealers.
  • the arrangement of the sliding seal has again the advantage that the latter does not come into contact with the mix.
  • closure lid for the discharge opening is rotatably mounted on the closure lid mechanism and is firmly connected to the rotating mixing container via a stationary seal in the closed state.
  • Stationary seals can be made from much less sensitive and robust materials than sliding seals and can also be pressed firmly against the sealing surfaces, so that their loading with mixed material can be easily accepted, since there is no wear on the seal without relative movement between the sealing cover and the opening edge .
  • a sliding seal that is sealed against the mixture is attached to the cover of the pressure container above the wall of the mixing container and / or at the upper edge thereof.
  • Such a seal has the advantage that mixed material (dust, sand, etc.) whirled up by the mixing tools does not reach the area of the pressure vessel outside the mixing vessel, where the more sensitive pressure-resistant sliding seals are located.
  • the above-mentioned object is also achieved in that, instead of the aforementioned bottom opening through the cover of the pressure vessel, a suction pipe which can be moved essentially perpendicularly to the cover plane and is sealed on its outside against the cover is arranged for the removal of absorbent mix.
  • the pressure container is essentially a cylindrical container with a bottom, cover and wall and the mixing container is essentially a cylindrical container with a bottom, wall and without Cover is.
  • Cylindrical containers are generally quite easy to manufacture and, on the other hand, are particularly suitable as pressure vessels due to their geometric shape.
  • the mixing container is rotatably mounted inside the pressure container. In this way, the principle of the intensive mixer can be applied.
  • the drive motor of the mixing container is arranged outside the pressure container and a shaft is provided as a driven means through the bottom of the pressure container and provided with a sliding seal, at the end of which a pinion is attached inside the pressure container, which is connected to a gear meshes at the bottom of the mixing container.
  • the motor is easily accessible and easy to cool, and the required sliding seal of the drive shaft lies outside the mixing container and is therefore not exposed to the influences of the mix.
  • a further advantageous embodiment of a mixer according to the invention is characterized in that the drive motor of the mixing container is arranged outside the pressure container and that a shaft which is guided by an elastic sleeve on the bottom of the pressure container and is provided with a sliding seal is provided as the output means, at the end of which Inside the pressure vessel, a friction wheel is attached, which abuts a drive ring of the mixing vessel.
  • the drive of mixing containers by means of a friction wheel has proven to be particularly low-maintenance and quiet.
  • the flexibility of the friction wheel also makes it elastic Bearing of the drive motor and the drive shaft required.
  • the sliding seal of the shaft or its surround can be connected to the housing of the pressure container via a sleeve, which can consist, for example, of a rubber plate.
  • a sleeve which can consist, for example, of a rubber plate.
  • the drive motor for the mixing tools is attached to the lid or side wall or on the machine frame outside the pressure vessel and via a shaft which is guided through the lid of the pressure vessel and provided with a sliding seal with the mixing tools inside the Mixing container is connected.
  • the motor is easily accessible and the sliding seal for the shaft of the mixing tools generally does not come into contact with the material to be mixed, since it is arranged on the cover of the pressure vessel.
  • the shaft can advantageously also be provided with a protective ring underneath the sliding seal.
  • a suction pipe is arranged through the cover of the pressure vessel that is movable essentially perpendicular to the cover plane and sealed on the outside against the cover for the removal of absorbent mix.
  • the discharge opening in the bottom of the mixing container can be replaced by the suction pipe.
  • the mix can then be pumped out of the mixer at the end of the mixing time be sucked.
  • the closure cap and the drive parts required for this are saved in this solution, and the diameter of the required sliding seals is limited to the diameter of a drive or bearing shaft for the mixing container, which in this case is also expediently arranged centrally.
  • the suction pipe is preferably arranged such that it can be raised and lowered so that there is no disruption of the mixture flow during the mixing process, during which the material to be mixed may be very viscous.
  • the seal around the intake manifold can e.g. be a compression fitting which on the one hand enables the suction pipe to be raised and lowered and at the same time serves as a locking device with the aid of which the desired height of the suction pipe opening is adjusted.
  • the person skilled in the art can select the seal and / or locking device that is best suited for the respective purpose.
  • the lower edge of the suction pipe can be adjusted so that the distance from the bottom of the mixing tank corresponds to the desired height of the mix.
  • the respective degree of filling then corresponds precisely to the average residence time of the mixed material.
  • the pressure in the suction pipe must of course still be below the residual pressure of the pressure vessel so that removal is possible at all. If necessary, the pressure vessel can also be briefly pressurized with low pressure during the removal of the mix by the suction pipe in order to accelerate the removal of the mix.
  • a vacuum flange for attaching a suction or vacuum pump line is attached to the lid of a pressure vessel according to the invention above the mixing vessel and a pressure flange for connecting a pressure line to the cylinder wall or on the lid of the pressure vessel outside of the mix seal just mentioned.
  • Such attached vacuum and pressure flanges are on the one hand independent of filling processes and on the other hand, gas supplied or extracted in this way always flows from the outer area of the pressure vessel into the mixing vessel, so that in this way it is also avoided that whirled up mix material in the outer area of the Mixing container arrives.
  • openings can be closed by pressure plates with pressure-resistant seals and in the wall of the mixing container at the same height by plates are closable openings with seals sealed against mixed material.
  • These openings make it possible to access functionally essential parts of the mixer, such as the mixing tools, from the outside or, for example, to line the mixing container from the inside with wear linings.
  • the wear coverings are fastened by simple through-bores in the wall and / or in the bottom of the mixing container, which allow simple and quick replacement.
  • a condenser for condensing gases pumped out of the mixture is arranged on the cover of the pressure vessel. It can be advantageous if the condenser for the backflow of the condensate is connected at its lowest point to the vacuum flange or another opening in the lid of the pressure vessel above the mixing vessel. So there is e.g. Mixing processes in which physical or chemical reactions generate thermal energy due to the mixing process and the mix may heating up in an undesirable manner. Such heating can be avoided by e.g. a partially gaseous constituent of the mixed material is pumped out, the further evaporation of this constituent forced by the pumping removing the heat of evaporation required for this from the mixed material. However, since the composition of the mix should generally not change, it is advantageous if the pumped gas condenses in a condenser (heat exchanger) and is then fed back to the mix in liquid form.
  • a condenser is also arranged on the cover of the pressure vessel, which at its lowest point is connected to an outlet which opens outside the mixing vessel.
  • the drain is attached so that it opens not only outside the mixing container but also outside the pressure container. At the end, the solvents can be recovered and used in the next batch.
  • Pressure and / or temperature measuring devices which are coupled to a control device for setting a specific pressure or a specific pump output, can be arranged on the cover of the pressure container above or directly in contact with the material to be mixed. Since pressure and temperature are dependent on one another for gaseous systems, temperature control can advantageously be carried out by appropriately adjusting the pressure.
  • Another possibility for regulating the temperature of the material to be mixed can be provided by a further embodiment of a pressure mixer in which the wall and bottom of the mixing container are hollow for the flow of a coolant and / or heating medium.
  • feed lines are arranged on the bottom of the pressure container next to the passage opening, which are passed through the sealing edge and open in the interspaces of three sliding seals which are located one above the other at intervals between the sealing edge and the outlet ring.
  • the seal required for the printing operation around the passage opening is thus designed so that at least two chambers are formed between several individual sealing rings, which are suitable for the supply and / or removal of cooling and / or heating media through appropriate supply lines.
  • the inside of the wall and the bottom of the mixing container are connected to the same spaces of the sliding seals in which the feed lines open, by means of holes drilled on the entire edge of the outlet ring.
  • the interior of the bottom and the wall of the mixing container is expediently divided into two regions by a further partition, one of which is connected to the inlet and the other to the outlet of the heating or cooling liquid and which are connected to one another at the upper edge of the mixing container wall .
  • the inflowing heating or cooling agent must flow along the entire bottom and wall surface of the mixing container before it flows into the drain, so that very effective heating or cooling is achieved.
  • Such a heating or cooling possibility of the mixing container is particularly advantageous when the mix contains hardly any gaseous constituents and temperature regulation by adjusting the gas pressure is not possible.
  • a further pressure sealing cover for the pressure container is provided. Both covers can be attached to the same swivel arm. While the pressure cap is already brought into its closed end position by the pivoting movement of the cap mechanism, the closing and pressing of the cap for the mixing container takes place by means of an additional drive attached to the pivot arm or the pressure cap, e.g. spring, hydraulic or pneumatic cylinder, electric motor, etc. the cover for the mixing container is rotatably mounted on the additional drive.
  • this embodiment can be expanded to the effect that the drive motors for the mixing container and the mixing tools are arranged inside the pressure container, so that the relatively small sliding seals of the drive shafts for the mixing container and the mixing tools can also be omitted.
  • the pressure-resistant mixer only stationary seals can therefore be used. This can be advantageous or even necessary if there are particularly large differences compared to atmospheric pressure or if toxic gases are used inside the pressure vessel.
  • the pressure-tight supply of electrical connections and coolants for the drive motors can be carried out in a conventional and known manner.

  • the pressure flange 13 is likewise arranged on the cover 27 of the pressure container 3, but is located outside the circle described by the seal 16. In this way, gas introduced through the pressure flange 13 first flows into the space of the pressure container surrounding the mixing container and from there through the seal 16, which only seals tightly for mixed material, into the mixing container 1.
  • openings 37 and 37a through which the interior of the mixing vessel 1 is made accessible, are provided at the same height by the covers 7 and 7a. This enables maintenance and repair work, for example on the mixing tools 17, or also the replacement of wear linings 23 with which the inside of the mixing container 1 can be lined.

  • the diameter of the outlet ring 25 and the sealing edge 26 is chosen so that the sliding seal 9 can be a seal in a commercially available shape and size.
  • FIG. 3 shows another form of a mixing container wall 3, which in this case is designed as a hollow wall and through which a coolant or heating medium flows.
  • supply lines 24 are inserted in a conventional manner in a pressure-tight manner through the bottom 31 of the pressure vessel 3 into the sealing edge 26 and open there in the interspaces of three annular sliding seals 9 arranged one above the other establish the connection from these spaces to the interior of the mixing container wall 31.
