Definitions

  • the invention relates to a mixing container with an upper-side filling opening, with a flange projecting in the radial direction outwards in the region of the upper-side filling opening for connecting the mixing container to the mixing head of an industrial mixing machine and with an underside lockable and openable outlet.
  • the invention further relates to an emptying station for such a mixing container.
  • Mixing containers of this type are connected to a mixing machine for mixing mixed material therein.
  • Such mixing machines are industrial mixers which are used for mixing, in particular, bulk material, typically powdered bulk material, such as is required for producing plastic granulate mixtures or else in the paint industry.
  • These mixing machines have a comparison with a frame pivotally mounted mixing head, which also serves to seal a mixing container containing the mixing container, which is connected for the purpose of mixing the mixed material therein to the mixing head. After connecting the mixing container to the mixing head a closed container is formed from the mixing head and the container containing the mix.
  • the mixing head has one or more connecting elements, for example a circumferential flange as a contact surface for a complementary connection flange of the mixing container and locking members for locking the mixing container to the mixing head. Due to the fact that in these mixing machines a mixing container containing the mix is connected to the mixing head, these mixers are also addressed as a container mixer.
  • the mixing head itself is pivotally arranged relative to the machine frame of the mixing machine, so that the mixing with respect to the mixing head in an overhead position, in which the mixing head at the bottom and the mixing container connected thereto are located at the top. In this position, the lower side discharge opening of the mixing container is after pointing up.
  • This overhead position is required for the mix to come in contact with the at least one mixing tool carried by the mixhead.
  • the rotationally driven mixing tool is used to generate a Mischgutstromes within the closed mixing chamber.
  • the duration of the mixing process determines the degree of mixing.
  • Such an industrial mixer is for example off EP 0 225 495 A2 known.
  • Mixing containers of the type described above are made of stainless steel, so that they meet the requirements placed on the container during mixing.
  • the filling opening of the mixing container is formed by the upper end of a ring-cylindrical wall. Adjacent thereto, in the direction of the spout, is a truncated cone section designed as a ring, by means of which the inner diameter of the container is tapered from a cylindrical diameter to the diameter of the spout.
  • a shut-off valve is installed to open and close it. This is usually manually operable from the outside by means of a lever. If the mixed material contained in such a mixing container is mixed, the mixing container is moved with the mixed mix to an emptying station.
  • the outlet is connected to the inlet of the next process station.
  • the shut-off flap is then opened, so that the mixed pourable mix contained in the mixing container can flow out of this.
  • the emptying of such a mixed container takes place in dependence on the downstream process station in one batch or in several smaller batches. In the latter case, the mixing container still serves as a storage container.
  • mixed material bridges When emptying pourable mixes mixed material bridges can form in the conically tapered section. In such a case, only the mix below such a Mischgutmaschine can flow out of the mixing container without additional measures.
  • Such mixed material bridges arise through compaction of the mixed material in the mixing container by reducing the pore volume, typically by means of a material setting process in the region of the tapered container section, favored by the weight of the mixed material located above.
  • a vibration motor or a knock generator is connected in the emptying station to the outer wall of the mixing container.
  • the mixture contained in the mixing container is set in motion or held during the process of emptying and thus fluidized in some way, which is counteracted the emergence of Mischgut viten during emptying. Arisen Mischgut viten can be destroyed by such a measure.
  • the invention is therefore the object of such a form a mixing container of the type that, even if filled with Mischgut viten tilting mix, without significant additional noise can be emptied as intended.
  • the mixing container comprises a mixing container forming the cavity of the mixing container with a flexible wall enclosing its cavity and a container frame holding the mixing container with the connection flange and the outlet which container frame the mixing container is held such that its cavity enclosing wall in the circumferential direction is at least partially accessible to effect a deformation thereof in the radial direction.
  • This mixing container has a flexible mixing container and a container frame in which the flexible mixing container is held. At least the wall enclosing the cavity of the mixing container has flexible properties, so that it can be deformed by the action of external forces, utilizing these properties. Thus, a deformation acting on the outside of this wall results in an indentation thereof, thus a change in the geometry of the cavity enclosed by the wall. Such a deformation of the wall simply destroys a mixed material bridge which may be formed in the cavity of the mixing container.
  • the mixing container is sufficiently dimensionally stable, so that this, when held in the container frame, the necessary for the process of mixing cavity, without collapsing, provides.
  • a container therefore has a sufficient wall thickness.
  • the mixing container is held by the container frame, wherein the mixing container is connected according to a preferred embodiment with its upper and its lower end to the container frame.
  • the mixing container is held in the direction of its height by the container frame.
  • the dimensional stability of the wall enclosing the cavity, to prevent an undesirable collapse of the same during the mixing process is sufficient.
  • the mixing process is performed with such a mixing container with a certain overpressure in the cavity containing the mix when the mixing container is connected to the mixing head of a mixing machine.
  • This overpressure which may be, for example, 0.3 to 0.5 bar above ambient pressure, builds up during the mixing process and may assist the shape retention of the flexible wall enclosing the cavity. Therefore, such a mixing container is particularly suitable for carrying out a mixing process when it is connected to a mixing machine, is provided by the anyway, to carry out the mixing process with a certain pressure.
  • the mixing container is made of a material which is elastically extensible at least to a certain extent. It is envisaged that when mixing a mixed material in a mixing container with such a container whose volume increases when forms an overpressure in the mixing cavity, for example in the aforementioned order of magnitude. The increase in volume associated with the pressure increase in the mixing container of the mixing container causes a slower pressure rise within the cavity.
  • mixing material is mixed in the mixing container, which may only be mixed with a maximum internal pressure and / or only with a maximum temperature effect in the mixing container. While limited by this condition, the duration of a mixing operation in conventional mixing containers, when using a mixing container of the type described above due to the only slower internal pressure increase, the mixing time can be made longer. This is set by the elasticity of the material chosen for the preparation of the mixing container and the wall thickness. In order to achieve a significant mixing time for the mixing time, for example, 10 - 20%, due to the size of such mixing containers (for example, 2000 liters) this already achieved with a relatively small wall expansion of the mixing container of the case.
