Definitions

  • the invention relates to a dual centrifuge according to the specified in the preamble of claim 1. Art.
  • standard centrifuges are used in the field of biology and chemistry for substance separation.
  • a standard centrifuge is understood to mean both table centrifuges and stationary centrifuges, which have a safety boiler and a safety lid, the bowl diameter being 15-65 cm, preferably 20-50 cm. It is possible to remove rotors, but also to exchange them. Since high speeds are required for the separation of mixtures, these reach maximum speeds of 25,000 rpm.
  • Dual centrifuges are already known from the state of the art in the field of laboratory technology, with which, in contrast to these standard centrifuges, no material separation is carried out, but very efficient mixing, homogenization, grinding processes, extractions or even tissue digestions are carried out.
  • rotary units are arranged in the rotor, which receive containers with samples to be processed and rotate about a different axis of rotation from the main axis of rotation of the rotor.
  • a further drive mechanism for the rotary units is provided in addition to the drive mechanism for the rotor.
  • the further drive mechanism is implemented in different ways in the various known dual centrifuges. So is in the DE 101 43 439 A1 discloses a dual centrifuge in which the further drive mechanism for the rotary units is mounted below the rotor.
  • the further drive mechanism consists of a fixed wedge disk on the Motor housing and a wedge disk connected to the rotary unit on the rotor, both of which are connected by a V-belt.
  • Another example is the one in the DE 10 20 12 105 819 A1 described dual centrifuge, in which a gear below the rotor is rotatably mounted on the housing of the centrifuge motor.
  • the rotary units each have teeth in their peripheral area, which engage in the gear.
  • the rotary units are also rotated about its axis of rotation, since the toothing meshes on the peripheral area via the rotationally fixed gear.
  • DC dual centrifuge
  • the further drive mechanism can also be integrated in a hollow shaft, as in the US Pat JP 2009119587 A discloses, however, this arrangement of the further drive mechanism makes the expansion and replacement of the rotor even more complicated.
  • the object of the invention is to develop a dual centrifuge while avoiding the disadvantages mentioned that rotors for dual centrifuges, hereinafter referred to as DC rotors, can be changed easily and quickly, especially without additional tools, and that also with and Also, other types of centrifuge rotors, such as angular rotors or swing-bucket rotors, may be used with the same dual centrifuge.
  • a dual centrifuge for mixing, homogenization, milling, etc. temporarily becomes a conventional centrifuge for separating samples. The dimensions of the centrifuge are still kept compact.
  • the invention is based on the finding that a rotor for a dual centrifuge can be designed such that it can be removed from the dual centrifuge or inserted into the dual centrifuge without further measures. Furthermore, the dual centrifuge and other types of rotors without further rotation mechanism, namely at least one angle head rotor or swinging rotor, be adapted to each other so that in the dual centrifuge both rotors with further rotation mechanism and rotors without further rotation mechanism can be equally used without it a functional impairment comes.
  • the drive for the further rotary mechanism of the DC rotor for example, mounted on the housing of the centrifuge motor gear can be designed and installed space-saving that conventional rotors, such as a swing bucket rotor or a fixed angle rotor, used without further adaptation in the centrifuge can be.
  • the dual centrifuge has a drive shaft, a mounted on the drive shaft, axially removable in a removal direction first rotor, which is designed as a dual rotor, with at least one rotary unit, a bearing for the rotor, which is connected to the drive shaft and holding the rotor at least counter to the removal direction, an opening in the first rotor, in which the drive shaft engages at least with the end region, and a further drive mechanism for the rotary unit or the rotary units.
  • the dual centrifuge has at least one second rotor of different types to the first rotor, but only one of the rotors can be arranged on the drive shaft, and wherein the second rotor is also adapted to the further drive mechanism for the rotary units.
  • the dual centrifuge has at least two second rotors, wherein a second rotor forms an angle head rotor and the other second rotor forms a swinging bucket, wherein the bearing, the drive shaft and the various types of rotors are adapted to each other. Only one of these rotors can be arranged on the drive shaft.
  • the other types of rotors without further rotation mechanism are also adapted to the drive means for the further rotating mechanism so that there is no functional impairment.
  • several types of rotors can be used in the dual centrifuge. With this centrifuge, samples can be processed in different ways, which requires different rotors.
  • the angle head rotor and the swing-bucket rotor have a geometry that is dimensioned such that when the angle head is mounted or swing-bucket rotor, the drive means for the further rotary mechanism for the rotor of the dual centrifuge is arranged without contact relative to the mounted rotor. This spacing significantly reduces or even eliminates the risk of damaging the further rotating mechanism or rotor without further rotating mechanism during operation.
  • This coordinated design of the swing-out and angle rotor ensures that it does not come into contact with the rotationally fixed gear.
  • rotationally fixed gear can be made as space-saving and flat construction, so that other rotors can be used without further measures.
  • the dual centrifuge is provided with a set of different types of rotors, each rotor of this set having a quick release for receiving and fixing onto the drive shaft.
  • This quick release may for example be a screw, e.g. can be easily and quickly solved or closed with an Allen key, or a pressure mechanism, which makes opening and closing even easier.
  • the drive means for the further drive mechanism is thus installed and / or adapted so that second rotors can be operated without adaptation in the dual centrifuge, in particular the drive means for the further drive mechanism is designed and installed so space-saving that previously for standard centrifuges provided rotors can be used and used without further rotation mechanism without adjustment in the centrifuge.
  • the drive means may be implemented as a single, very small gear.
  • the drive means for the further drive mechanism may be formed by a rotatably mounted gear, in which engages the teeth of the rotary unit with insertion in the arranged in the centrifuge dual rotor or with insertion of the dual rotor with the rotary units in the centrifuge.
  • non-rotatable gear and the gears of the rotating units of a dual rotor so have a coordinated geometry that this when inserting the dual rotor with the rotating units or each of the rotary unit in the arranged in the centrifuge rotor automatically - without further action - interlock.
  • Another advantage here is that it is also possible with such a space-saving designed drive means for the further drive mechanism, this subsequently incorporated into a centrifuge developed for standard purposes and then to use this centrifuge for a dual centrifugation. This results in very low costs when using a centrifuge series housing. Because there are many different packages available for operation as standard centrifuges, it is very easy to find an existing optimal centrifuge standard package for certain sets of DC rotors or non-dual rotors. The operation of many different DC rotors is hereby easily possible. In addition, this solution is very inexpensive, since existing standard centrifuges can be easily converted by a gear and a suitable DC rotor in a dual centrifuge.
  • a safety boiler in which the rotor and the bearing are arranged, and in which the drive shaft protrudes at least partially. Due to a one-piece design of boiler wall and boiler bottom and an adaptation of a provided for the drive shaft penetration in the boiler bottom to the dimensions of the drive shaft ensures that not only in a rotor crash flying parts remain in the safety boiler, but that even in an accident escaping fluids can not escape from the boiler and contaminate the work area. Further, the largest diameter of a rotor of the set of various types of rotors is at most 96% of the diameter of the safety vessel. This measure prevents rotors or their accessories from touching the boiler if the imbalance of the system is tolerable or if vibrations are inherent in the system. The compact design of the centrifuge is retained, so that no increased space requirement is the result of this measure.
  • the drive shaft is designed as a solid shaft.
  • the necessary stability in the drive of the respective rotor is more easily achieved and allows easier change.
  • the drive means of the further drive mechanism is a toothed wheel, which is fixedly connected to the motor housing and is penetrated by the drive shaft.
  • This type of mechanism is easy to implement, inexpensive and comparatively less prone to failure.
  • a set of different rotors of a dual centrifuge having different ratios is provided between the further rotating mechanism and the rotary unit.
  • rotors are available with different reverse rotation ratios between the rotating body and the rotor and consequently different relative rotational speeds of the rotating units, from which, depending on the intended use, the suitable one can be selected.
