Definitions

  • the invention relates to a shaking device for shaking of liquid provided in containers.
  • shaking the container becomes, for example, that in the containers provided liquid mixed or its surface enlarged to increase the oxygen uptake of the liquid improve.
  • Such shaking devices have a shaking table, on which the containers can be attached.
  • the shaker table is eccentrically mounted on a flywheel, for example is driven by a belt drive. Due to the eccentric circular motion of the shaking table along with the centrifugal forces occur on containers arranged on it. Due to the centrifugal forces that occur Stability of the shaker reduced.
  • the object of the invention is the stability of a Shaker also for masses to be shaken different sizes to improve.
  • a balance weight is on the flywheel arranged that depending on the size of the shake Mass can be adjusted.
  • This is the Balance weight along a guide device radially to Flywheel can be moved continuously.
  • the Distance between the balance weight and the axis of rotation of the Flywheel is the size of the balance weight generated centrifugal force changeable.
  • the bigger the too is shaking mass the further the balance weight along the guide device with respect to the axis of rotation of the Flywheel shifted outwards. It is therefore possible that the centrifugal force caused by the mass to be shaken completely compensated by the balancing mass becomes.
  • the stability is even with different masses to be shaken considerably improved since the location of the Balance weight before each shake can be adjusted.
  • the total weight to be shaken is due to the balance weight Mass, i.e. the mass of the shaker table, the container, the Liquid and possibly additional on the shaking table fixed objects compensated.
  • the balance weight Mass i.e. the mass of the shaker table, the container, the Liquid and possibly additional on the shaking table fixed objects compensated.
  • two Balance weights may be provided, with a balance mass is firmly connected to the flywheel and the non-varying Mass of the shaking table compensated.
  • the second Compensating mass can be moved radially to the flywheel and equal to the varying mass of the liquid, the container and the like out. It is also possible to use the sliding balance weight to attach an additional weight that together with the balance weight is displaceable to larger Compensate centrifugal forces.
  • a dovetail guide can be used as the guide device groove running radially to the axis of rotation of the flywheel and suitable clamping device may be provided.
  • the guide device essentially has one arranged perpendicular to the axis of rotation on which the Balance weight is displaceable in the longitudinal direction.
  • That Balance weight have a threaded hole so that it through Turning is slidable.
  • a change in the position of the balance weight is during the shaking process by the Self-locking of the thread avoided.
  • That Balance weight have a through hole without thread, through which the guide spindle is passed.
  • the lead screw in a threaded hole in the flywheel held so that the position of the balance weight by turning the lead screw is changeable.
  • the guide spindle is preferred non-rotatably connected to the flywheel.
  • the balance weight that has a through hole without thread is through Turn an adjusting nut on the lead screw slidable.
  • An adjustment key can be used to turn the adjustment nut these are put on.
  • the adjustment key has one Stock with longitudinal scale attached.
  • the current position of the balance weight with respect to the Axis of rotation of the flywheel can be read. From this one can the centrifugal force caused by the counterweight as well as calculate the mass to be shaken by the current Position of the counterweight is compensated.
  • the weight of the mass to be shaken directly on the scale applied so that by the location of the balance weight compensated mass to be shaken directly on the adjustment key can be read.
  • the in the containers provided liquid is first the weight of one on the Load to be arranged on the shaking table.
  • the load closes the weight of all containers and the one inside contained liquid and possibly the weight of a tray on which the containers are held.
  • a determination of Mass of the shaking table is not necessary as this is known is and remains unchanged.
  • the weight of the load becomes the distance of the counterweight to the axis of rotation of the flywheel depending on the size of the Loading by moving the radial continuously Balance weight set.
  • the distance of the counterweight is preferably determined by means of the Adjustment key carried out on a scale, depending on Position of the adjustment key on the scale that the position of the Balance weight corresponding to the weight of the load is.
  • the shaker has a flywheel 10 which is made of a flywheel base 12 and a cylindrical flywheel attachment 14 exists.
