Definitions

  • the invention relates to a system of an industrial mixing machine, comprising a mixing head equipped with means for connecting the same to a container containing a mixed material, which mixing head is pivotably mounted relative to a frame in such a way that the mixing container formed from the mixing container and mixing head can be pivoted to carry out a mixing process is, and has at least one rotationally driven mixing tool, and comprising a cleaning container for cleaning the mixing head of the mixing machine.
  • Industrial mixing machines are those used for mixing, in particular, bulk material, typically powdery bulk material, such as is required, for example, for the preparation of plastic granulate mixtures or also in the paint industry.
  • Mixing machines of this type have a mixing head which is mounted pivotably with respect to a frame and which simultaneously serves to close a container containing the material to be mixed.
  • This container is typically a mixing container.
  • the mixing container is connected to the mixing head for the purpose of mixing its contents, so that a closed mixing container is then formed by the mixing head and the container.
  • the mixing head and the mixing container have complementary connection means so that the mixing container can be connected to the mixing head.
  • connection is typically made via a flange projecting outward in the radial direction from the mixing container or the mixing head, the two flanges being pressed against one another with the interposition of a seal.
  • Piston-cylinder actuators for example, are used for this purpose.
  • the mixing head is pivotably mounted on a frame in order to bring the mixing container formed from the mixing head and mixing container into its mixing position, in which the mixing tool or tools of the mixing head are arranged at the bottom.
  • the aim is to achieve the desired mixing in the shortest possible time.
  • care must be taken that the heat input is not too great, since otherwise the particles to be mixed can stick to one another and to the inner wall of the mixing head or also to the mixing tool or tools.
  • a cleaning device is known with which surfaces with a complex geometry can be cleaned, for example in the case of a vulcanization mold for tires. Jet nozzles are used which are aimed at the surface of the vulcanization mold to be cleaned.
  • U.S. 4,375,740 A and DE 297 19 266 U1 Further cleaning devices are known in which the surface to be cleaned is cleaned by jet nozzles operated with compressed air, for example. Cleaning of surfaces, especially those that do not have complex geometry, is over EP 1 898 003 A1 or. DE 85 04 449 U1 known. For this purpose, cleaning devices with centrifugal wheels are used, which throw the items to be cleaned onto the surface to be cleaned.
  • An industrial mixer is off DE 10 2013 111 158 B3 known. If a different material is to be mixed after mixing a first material to be mixed with the mixer, the mixing head must be carefully cleaned beforehand so that the material of the previously mixed material that has not remained in the mixing head gets into the material to be mixed subsequently and thus contaminates it. This is especially true when the different mixes contain different color pigmentation.
  • the cleaning of such a mixing head includes the removal of mixed material dust adhering to its inner surface and the removal of mixed material that is caked on the inner wall of the mixing head. Additionally the tools must be cleaned. To clean the mixing head, the tools are dismantled and manually subjected to liquid cleaning. The inside wall of the mixing head is also subjected to liquid cleaning, often using liquid jet devices.
  • the cleaning is carried out manually. Since cleaning has to be carried out very carefully, the cleaning process takes a correspondingly long time.
  • cleaning has to be carried out very carefully, the cleaning process takes a correspondingly long time.
  • it must be ensured after the cleaning process that the tools and the inner wall of the cleaning container are completely dry so that no cleaning liquid droplets get into the mixed material to be mixed.
  • drying takes place in ambient air, which in addition to the actual cleaning process also results in a corresponding downtime of the mixer.
  • the invention is based on the object of proposing a device with which the cleaning process of such a mixing head can be simplified and, in particular, also carried out automatically.
  • the cleaning container has a cleaning container which has an opening and connection means for connecting the cleaning container or its container to the mixing head.
  • connection means are typically those that have mixing containers that are otherwise to be connected to the mixing head of the mixing machine for the mixing process.
  • the advantage of cleaning the inside wall of the mixing head in a closed space formed by the mixing head and the cleaning container or its mixing container is that no additional drainage devices for liquids or other covers need to be provided to avoid soiling the area around the mixing head.
  • the inner surface of the mixing head i.e. the surface that comes into contact with the material to be mixed during mixing operation of the mixing head, is cleaned by means of a blasting process.
  • At least one centrifugal wheel of a centrifugal jet device is arranged in the cleaning container.
  • the inside wall of the mixing head is therefore cleaned dry.
  • the throwing fan of the centrifugal wheel is directed towards the inside wall of the mixing head.
  • the throwing fan is typically smaller than the surface of the inner wall of the mixing head facing the centrifugal wheel.
  • the centrifugal wheel can be set up with respect to the throwing direction of the blasting agent, so that in the course of such a setting the entire inner surface of the mixing head successively reaches the area of the blasting agent throwing fan at least once. The centrifugal wheel is thus moved in relation to its throwing fan on a predetermined path of movement for cleaning the inner surface of the mixing head.
  • the mixing head is typically cleaned in a position of the mixing head and the cleaning container connected to it, in which the cleaning container is at the bottom and its opening on the top is directed towards the downwardly open mixing head. This also corresponds to the typical position of the mixing head when a mixing container for mixing mixes is connected to it. With the mixing head and cleaning container in such a position, the blasting agent is thrown against the force of gravity onto the inner surface of the mixing head by the centrifugal wheel. Those from the surface of the Mix head removed mixed material particles then fall down together with the material removed from the surface due to gravity and thus out of the mixing head and into the cleaning container, can be collected therein and carried away.
  • a particular advantage in cleaning the inner surface of a mixing head by blasting lies in the fact that such cleaning is carried out dry and therefore there is no risk that cleaning liquid residues could be introduced into it in a mixing process following cleaning of the mixing head.
  • the abrasive used will be one that does not damage the inner surface of the mixing head. This therefore has a lower hardness than the hardness of the material forming the inner surface of the mixing head.
  • Another advantage of such a cleaning of the mixing head is that in principle the at least one tool for the process of cleaning the mixing head can also remain in it. This may not apply to every mixed product residue to be removed from the mixing head, but it does apply to many. In such a case, when cleaning a mixing head, the removal and installation of the at least one mixing tool and its separate cleaning are saved.
  • the centrifugal blasting device the centrifugal wheel of which is arranged inside the cleaning receptacle of the cleaning container, has a blasting agent feed via which the blasting agent is fed to the centrifugal wheel.
  • a blasting agent which is not stable under ambient conditions is used.
  • These are typically dry ice particles, for example in pellet form.
  • Cleaning the inner surface of the mixing head including its tools by dry ice blasting in the closed cleaning container has several advantages. Due to the low Mohs hardness of dry ice particles (hardness 2 according to Mohs), damage to the inner surface of the mixing head and / or the tool (s) located therein is excluded.
  • the cleaning effect is particularly effective in relation to the mixture adhering to the inner surface of the mixing head or its at least one tool, which can be a plastic compound, for example.
  • the mixed material adhering to the inner surface of the mixing head is removed less by the kinetic energy during dry ice blasting than by the embrittlement caused by the dry ice bombardment and the associated flaking of the inner surface of the mixing head.
  • the dry ice particles hit the dirty inner surface of the mixing head, they sublime, which leads to immediate embrittlement of the adhering mix.
  • the volume of dry ice particles hitting the inner surface of the mixing head increases by 700 to 800 times the volume of the particles or pellets.
  • a suction device is connected to the cleaning container or its cleaning receptacle, through which the gas (CO 2 ) produced during sublimation together with the mix removed from the inner wall of the mixing head and / or the tool (s) can be discharged from the cleaning container.
  • the pressure resulting from the sublimation in the cleaning container formed by the mixing head and cleaning container supports the expulsion of the gas, which carries along the particles detached from the inner surface of the mixing head, out of the cleaning container.
  • the suction can be equipped with a suction pump to support this process.
  • the gas / mix particle mixture withdrawn from the cleaning container can be cleaned, for example, in an air classifier, wherein the mix removed from the mixing head can be returned to its original destination.
  • a flushing line can be connected to the cleaning container or its cleaning receptacle, via which a gaseous flushing fluid, for example After completion of the cleaning process, air is introduced to rinse the interior of the cleaning container to remove any mixed material dust that may still be present therein.
  • plastic particles or also particles made of aluminum or an aluminum alloy are used as the blasting material.
  • the cleaning process is sometimes a bit more abrasive with such a material than with dry ice.
  • the cleaning space, formed from the mixing head and the cleaning container connected to it can be flushed with a gas, for example ambient air, after the blasting process.
  • the cleaning container can also be connected to the mixing container automatically and thus automatically.
  • the cleaning container is typically articulated to the frame of the mixer and is connected to the mixing head when the mix to be mixed is changed to carry out the cleaning process and is removed from it again after the cleaning process has ended, so that the next mixing container is then immediately sent to the Mixing head can be connected to carry out another mixing process. It goes without saying that with such a cleaning container the downtimes of the mixing machine necessary for cleaning the mixing head are considerably reduced.
  • a resistant abrasive is used as the abrasive for the removal of mixed material adhering to the inner wall of the mixing head and / or the tools.
  • a stable blasting agent for example Plastic particles and / or particles made of aluminum or an aluminum alloy and in a second blasting step the blasting is carried out with dry ice and thus with a non-resistant blasting agent.
