Definitions

  • the invention relates to a device for mixing the contents of a bioreactor with a stirrer, which is attached to a standing on the bottom of the reactor vessel stand having a vertical column to which the agitator is attached.
  • the object of the invention is to improve a device of the type mentioned so that it can be used and removed with little effort and in the shortest possible time.
  • This object is achieved in that the particular metal pillar is fixed with its lower end on a particular metal support plate having feet on its underside feet for unsecured on the container bottom.
  • Such a device may be free within the container without attachment to the container bottom or to the container wall. Thus, only a portion of the top cover of the container needs to be opened briefly to insert and remove the device. This can be z. B. by a crane. There is no need to install and loosen fittings, nor does the container need to be emptied.
  • the feet of the support plate have a height such that they penetrate the deposit layer located on the container bottom.
  • a receptacle in particular a hook or an eyelet for a load chain or a load cable is attached to the top of the column.
  • a receptacle in particular a hook or eye for a load chain or a load rope is attached to the top of the column.
  • At least one other stirrer be attached to the column at the top of the column below or at the level of the floating ceiling of the liquid container contents ,
  • the agitator has at least one propeller whose horizontal axis is driven by a submersible motor.
  • a sufficient weight with high stability is achieved if the support plate and / or the column are made of steel.
  • the device for mixing the contents of a bioreactor has a vertical column 1 of a metal profile in particular a metal hollow profile, preferably made of steel, to which the agitator 2 is attached laterally, which is located below the water level 3 and has a propeller 4, the horizontal axis through an electric submersible motor 5 is driven.
  • the lower end of the column 1 is mounted centrally on a rectangular horizontal support plate 6 made of steel, in particular welded or screwed, at the bottom of three feet 7 are fixed, projecting vertically downwards and stand unsecured on the bottom 8 of the container.
  • the height or length of the feet 7 is selected so that they pierce lower, located on the bottom of the container deposits in particular of sand and / or mud and reach the bottom 8 safely.
  • the support plate 6 also have different outer dimensions and outer shapes, in particular, they may be square, circular or triangular shaped.
  • an eyelet 10 is welded to allow easy attachment to a crane or hoist. Instead of an eyelet but can also be arranged a hook.
  • a direction finding device 11 is attached to the upper end of the column 1 with a horizontal bearing profile 12, wherein the profile 12 via a vertical spacer profile 13 at the top End of the column 1 is detachably plugged or screwed.
  • the profile 13 ensures that the profile 12 is located above the water level 3 and the upper edge 14 of the container. Markings on the upper edge of the container allow easy alignment of the device within the container.
  • the support plate 6 and / or the column 1 consists of a material deviating from metal, in particular concrete.
