Definitions

  • the present invention relates to an interior container for easing the cleaning of a forced action mixer.
  • Forced action mixers are generally used for mixing material like cement and granulate.
  • the forces during mixing can be quite large; hence the mixing chamber in a forced action mixer has a chamber wall, which has a thickness of a few centimetres of steel metal.
  • the chamber walls must have a very high stress-resistance.
  • the interior of the chamber walls is made of steel as steel is capable of withstanding these large forces.
  • the granulate may be removed from the mixing chamber by pouring petrol into the mixing chamber and igniting the petrol. This will remove the granulate stuck to the interior of the granulate, but it will significantly reduce the lifetime of the forced action mixer.
  • Cement stuck to the mixing chamber may only be removed by hammering the cement; on average, this takes two man hours.
  • the process of hammering the cement is neither safe nor ergonomic, as a person has to stand on a ladder or the like above the mixing chamber of a forced action mixer while at the same time swinging the hammer downwards into the mixing chamber.
  • the person cleaning the mixing chamber has to use large swings in order to have sufficient power for breaking the cement.
  • the cleaning may lead to hearing damage as the cleaning produces loud noise.
  • the interior of the mixing chamber is further cleaned by a water pressure cleaner and the fragments of the cement are usually just left on the construction site.
  • the problem with the cleaning and maintenance of the forced action mixer is particularly a problem for companies having a forced action mixer rental service as the renters tend to not clean the forced action mixers properly after use.
  • an interior container for fitting into an interior of a mixing chamber of a forced action mixer and removal from the interior of the mixing chamber.
  • Said interior container comprises a bottom part and a wall part for connecting with a bottom part.
  • Said bottom part has a periphery, an outlet aperture neighbouring the periphery, and a centrally positioned aperture.
  • the periphery of the bottom part is seen as the periphery of the bottom part without the two features of an outlet aperture and a centrally positioned aperture.
  • the wall part is a rectangular piece having two side lengths similar to or slightly longer than an interior circumference of a mixing chamber and two side lengths similar to the height of the mixing chamber.
  • One of the benefits of the wall part being a rectangle is that it is easily stackable.
  • the wall part is made of flexible material having a sufficiently large restoring force.
  • the restoring force helps securing the wall part inside the mixing chamber as it will create an outwards facing force relative to the centre of the mixing chamber.
  • the wall part works as a wrap.
  • Another advantage with this embodiment is that pockets of free space are limited as the wall part and interior of the mixing chamber are locked tightly. This is important because if material gets in between the wall part and the mixing chamber, then it will lead to an indentation into which one of the shovels of the forced action mixer may grip, thereby violently ripping the interior container to shreds. In such case, the interior container will be ripped apart in a second.
  • the interior container has sealing means for sealing the free end of a wall part with an upper part of a mixing chamber wall in a forced action mixer.
  • the sealing means are a top list able to grip the interior side of the wall part and the exterior side of the mixing chamber.
  • the wall part is secured in a simple manner.
  • the sealing means is a strong tape e.g. gaffer tape, which is used to secure the wall part to the mixing chamber.
  • the sealing means are attached to the free end of a wall part. In this way the user will not forget to properly seal the wall part.
  • the interior container has a non-stick interior surface.
  • the interior container may be reused as the cement or granulate will not stick to the surface.
  • the material can be removed by cleaning the interior container with water.
  • the granulate and the cement can be removed from the container without the use of a water pressure cleaner.
  • the interior container further comprises an assembly list connected to a part of the periphery of the bottom part, said assembly list has an upwards facing protrusion for protecting the connection between a bottom part and a wall part.
  • the assembly list prevents the shovels from ripping the interior container to shreds.
  • the assembly list and the bottom part are a monolith.
  • the user will not forget to properly protect the connection between a bottom part and a wall part.
  • the interior container is a monolith.
  • the interior container is made of polyethylene high density (PEHD).
  • PEHD polyethylene high density
  • PEHD has all of the previously mentioned properties as it is very resilient. Thus, it will engage tightly with the interior side of the mixing chamber, when the wall part is a rectangle.
  • PEHD has a non-stick surface, so granulate and cement will not stick to the interior container.
  • PEHD is a strong material and the impact strength of PEHD when being notched is large; hence it is can be exposed to being beaten without deforming.
  • the material is PEHD 300 as it has good vacuum forming properties.
  • the interior container is made of food approved polyethylene high density (PEHD).
  • PEHD polyethylene high density
  • the forced action mixer can be used to make dough e.g. dough for pancakes.
  • the interior container is made of food approved PA-66 or PA-6.
  • a forced action mixer comprises a mixing chamber having a lower chamber outlet aperture and a motor driven driveshaft connected to a removable mixer head.
  • the mixer head comprises one or more shovels.
  • the forced action mixer further comprises a removable interior container.
  • one or more shovels have non-stick surfaces. This will further ease the cleaning of the forced action mixer.
  • shovels are made of PEHD.
  • shovels are made of PEHD 300.
  • PEHD and in particular PEHD 300 are that they have non-stick surfaces, hence cement and granulate will not stick to the shovels.
  • PEHD shovels are attached to the metal shovels of a removable mixing head.
  • the effect of the PEHD shovels is that they remove the risk of a stone getting stuck between the wall part and the shovels, as the PEHD shovels are flexible. This will lead to reduced strain on the interior container and it will lessen the scratching of the interior side of the wall part. The non-stick property of the interior surface of the interior container is reduced when the surface is damaged. Thus, the PEHD shovels will prolong the lifetime of the interior container.
  • the shovels are made of food approved PEHD 300.
  • a method for inserting an interior container into a forced action mixer comprises one or more acts of:
  • Example Use of an interior container in a forced action mixer for easing the cleaning of a forced action mixer
  • An interior container is inserted into a forced action mixer by first detaching the removable mixer head from the driveshaft.
  • the interior container is then inserted into the mixing chamber of the forced action mixer.
  • the removable mixer head is then reattached onto the driveshaft. Thereby, the forced action mixer is ready to mix e.g. cement.
  • cement components are then added to the forced action mixer and the mixing commences.
  • the cement is removed from the mixing chamber through the lower chamber outlet aperture.
  • the forced action mixer can be cleaned by water from a bucket or a water hose. This is possible due to the non-stick interior surface of the interior container. In some circumstances it may be necessary to use a water pressure cleaner.
  • the interior container can just be replaced by a new interior container as it is a relatively inexpensive product compared to the forced action mixer.
  • the cement left-overs can be collected in a bucket or a wheel barrel through the lower chamber outlet aperture and then be moved into a trash container. Hence the amount of small pieces of cement on the construction side can be limited.

  • An interior container 100 is fitted into the forced action mixer 200, said interior container 100 having a wall part 110 and a bottom part 140.
  • the effect of the PEHD shovels 250 is that they remove the risk of a stone getting stuck in between the wall part 110 and the shovels 250 as the PEHD shovels 250 are flexible. This will lead to reduced strain and it will lessen the scratching of the interior side of the wall part 110. The non-stick property of the interior surface of the interior container 100 is reduced when the surface is damaged. Thus, the PEHD shovels 250 will prolong the lifetime of the interior container.
  • the mixing of the components is increased as the material is constantly being mixed, this effect is further increased by the fact that the material will slide down the wall part 110 due to the non-stick surface of the wall part 110. This will increase the yield and it will also ease the cleaning as less material needs to be removed.
