Definitions

  • the invention relates to a centrifuge according to the type specified in the preamble of patent claim 1.
  • centrifuge During the operation of a centrifuge, undesirable heat is generated which is harmful to the material to be centrifuged.
  • a particular problem here is that the centrifuge rotor, the rotation of which and the resulting air friction causes a large part of the heat, is usually arranged for safety reasons in a safety chamber that is tightly closed by a lid. This makes it difficult for the heat to escape from it.
  • Biological samples often require a temperature of 4°C to be maintained during centrifugation. Active cooling is therefore indispensable, especially with longer operating times, high speeds and sample temperatures below ambient temperature.
  • a refrigerant flows in a refrigeration circuit, which is separated into a high-pressure and a low-pressure area by a throttle and a compressor. After heat has been removed from the refrigerant in the high-pressure area in a condenser, it flows in the low-pressure area in, for example, spirally arranged lines around a safety tank in which the rotor of the centrifuge is arranged, and in the process extracts heat from the safety tank.
  • the JP H07 144 155 A aims to provide a centrifugal separator equipped with a water cooler capable of precisely controlling the temperature by controlling the air temperature in the bowl of the centrifuge by controlling the operation of a pump.
  • a water cooler 20 is connected to a connecting pipe.
  • a chilled cooling liquid is sent to the centrifugal separator to cool the air in the bowl.
  • a bowl air temperature regulator opens the contact of a relay and the supply of cooling liquid is stopped.
  • the DE 10 2012 002 593 A1 relates to a centrifuge with a compressor cooling device and a method for controlling a compressor cooling device of the centrifuge.
  • the centrifuge includes a centrifuge bowl and a compressor cooling device, which has a refrigeration circuit, an evaporator, a condenser and a compressor.
  • a controllable throttle device for regulating the refrigerant flow is provided in the refrigeration circuit of the compressor cooling device. It is the object of the invention, while avoiding the disadvantages mentioned, to create a centrifuge whose cooling is efficient and, at the same time, harmless both from the point of view of safety and from the point of view of environmental protection.
  • the invention is based on the finding that by dividing the cooling circuit into a safety-critical area and a separate safety-related non-critical area, this task can be solved in a simple manner, particularly if different heat transfer mediums—refrigerants—are used in the two areas.
  • the centrifuge has a centrifuge housing, a safety tank arranged in the centrifuge housing, an inner space delimited by the safety tank, a rotor arranged in the inner space, and a cooling system arranged in the centrifuge housing for cooling the inner space.
  • the refrigeration system comprises a compressor, a condenser and an evaporator, which are connected to one another via duct means.
  • the cooling system has a primary circuit with primary line means and a secondary circuit with secondary line means, the primary circuit comprising the compressor, the condenser and the evaporator, which is part of a heat exchanger, and the secondary circuit flowing through the heat exchanger and cooling the safety boiler.
  • a pump is provided in the secondary circuit to ensure a constant flow of the heat transfer medium and thus efficient cooling of the safety boiler. It is therefore possible to use different heat transfer media in the two circuits, depending on the safety requirements, which result in further design options and targeted safety measures to take for the corresponding circuit.
  • a conventional combustible refrigerant flows in the primary circuit, which has a large specific enthalpy of vaporization at comparatively low procurement costs.
  • the primary circuit is located below the secondary circuit and the safety tank. This significantly reduces the risk of the primary circuit being damaged in the event of a rotor crash and a blowout of the safety tank.
  • the primary circuit is offset laterally to the secondary circuit in the centrifuge housing, a significantly more compact design of the centrifuge can be realized, especially with regard to the vertical expansion.
  • a safety wall spatially separating the two circuits is provided between the primary circuit and the secondary circuit. The risk of damage to the primary circuit in the event of a rotor crash and a breakdown of the safety boiler is further reduced if the primary circuit is offset to the side of the secondary circuit.
  • the safety tank is fixed in the centrifuge housing via a clamp connection, which allows the safety tank to move relative to the centrifuge housing in the event of a rotor crash.
  • a movement, in particular a rotary movement, of the safety boiler is initiated by the rotor impacting the safety boiler or by the rotor parts impacting the safety boiler and the resulting angular momentum, which is braked by the clamp connection.
  • the energy of the crash acting on the centrifuge housing is significantly weakened or completely eliminated, which improves the protection of the primary circuit from damage.
  • At least one additional mass element is arranged in the centrifuge housing in order to stabilize the centrifuge housing. This stabilization also serves to protect the primary circuit from the effects of the angular momentum that occurs in the event of a rotor crash.
  • the protection of the primary circuit can also be improved in that the primary line means are made of a mechanically stronger material than the secondary line means.
  • predetermined breaking points are provided on the secondary line means.
  • the mechanical connection between the secondary circuit and the primary circuit is separated and this prevents the impulse from being transmitted via the secondary Line means is directed into the area of the primary circuit and causes damage there.
  • the safety tank is preferably surrounded by a separate, in particular cylindrical, protective wall that is concentric with the safety tank. This further reduces the risk of damage to the primary circuit or the centrifuge housing in the event of a rotor crash.
  • the predetermined breaking points mentioned above are provided at the points at which the secondary line means reach through the cylindrical protective wall.
  • the secondary line means are easily sheared off by the protective wall during a relative movement, in particular a rotary movement, of the safety chamber with respect to the centrifuge housing.
  • a predetermined breaking point can be formed in the secondary line means, for example by weakening an area of the line means.
  • the predetermined breaking point can also be formed solely by assigning a shearing device to an area of the conduit.
  • the shearing device is activated during a relative movement, in particular a rotary movement, of the safety tank by the line means being moved towards the shearing device and/or the shearing device towards the line means.
  • the shearing device cuts through the conduit in the area assigned to it.
  • insulating and/or insulating materials are provided in the primary circuit, in particular between the compressor, the condenser and the evaporator. Insulation materials ensure greater stability, especially when the primary circuit is subjected to a large external impulse. In particular, it is prevented that the compressor, which is mounted on elastic damping elements, can be torn from its anchorage and the pipelines rupture. Another positive property of insulating materials is that they increase the efficiency of the refrigeration components. For example, rigid foam moldings are well suited to fulfill these two tasks and as insulation and to serve as an insulator. It is particularly advantageous if the molded parts have integrated channels that are used on the one hand for laying cables and on the other hand for a defined air flow.
  • a positive secondary aspect of this invention is that the demands on the line means that are provided in the secondary circuit are significantly lower than the demands on the line means that are provided in the low-pressure area of a conventional cooling device with a cooling circuit.
  • the operating pressure in the secondary circuit of a cooling device according to the invention is still significantly lower than in the low-pressure area of a conventional cooling device.
  • damage to the line means in the secondary circuit does not pose any safety risks. Consequently, instead of rigid, massive and expensive line means such as copper pipes, flexible hoses can be used here, for example. This reduces the construction effort and lowers the cost of the centrifuge.
  • FIG. 1 a schematic perspective view of a centrifuge 10 according to the invention is shown.
  • the housing is not shown; the arrangement of the housing cover 13a and the side walls 13b can of 3 be removed.

  • a combustible refrigerant 54 flows in the primary pipelines 29.
  • the safety boiler 14 is surrounded by secondary pipelines 34, which can only be partially seen in this figure, which essentially form a secondary circuit 62 (see 2 ) form.
  • a non-combustible heat transfer medium 64 flows in the secondary pipelines 34.
  • the structure of the primary circuit 52 and the secondary circuit 62 is shown in 2 again illustrated by a schematic representation.
  • a protective cylinder 18 is arranged concentrically around the safety tank 14 and is fixed, in particular horizontally, by four clamping elements 38 which are fixed at equal distances from one another on the outer circumference of the protective cylinder 18 on the base plate 12 . From this perspective, however, only one clamping element 38 can be seen.
  • the protective cylinder 18 prevents rotor parts flying around from spreading over a wide area, which could penetrate the centrifuge wall and cause major damage.
  • a safety wall 36 is arranged on the base plate 12 between the safety tank 14 and the compression refrigeration unit 20 .
  • the secondary circuit 62 flows through the heat exchanger 30.
  • two recesses 34a and 34b are provided in the safety wall 36, through which the pipelines 34 of the secondary circuit 62 each pass.

  • a pump 32 for conveying the non-combustible heat transfer medium 64 is arranged between the heat exchanger 30 and the recess 34a, through which the pipeline 34 runs back to the safety boiler 14.
  • the primary circuit 52 On the hot side 50 is the primary circuit 52, in which a flammable refrigerant 54 flows, with the compression refrigeration unit 20, which comprises the compressor 22, the condenser 24, the fan 25, the throttle 28 and the evaporator 26, which are connected via primary pipes 29 are connected to each other.
  • the compression refrigeration unit 20 which comprises the compressor 22, the condenser 24, the fan 25, the throttle 28 and the evaporator 26, which are connected via primary pipes 29 are connected to each other.
  • the evaporator 26 is part of a heat exchanger 30, through which the pipes 34 of the secondary circuit 62 also flow.
  • the primary circuit 52 and the secondary circuit 62 are thus thermally coupled via the heat exchanger 30 .
  • the heat extracted from the safety boiler 14 is transferred from the non-flammable heat transfer medium 64 from the secondary circuit 62 in the heat exchanger 30 to the flammable refrigerant 54 in the primary circuit 52 .
  • the transferred heat is released from the combustible refrigerant 54 to the ambient air 56 via the condenser 24 .
  • the use of the fan 25 improves the heat dissipation. Compression refrigeration units are known in principle, so that further explanations are unnecessary.
  • FIG. 3 is a side view, partially in section, of the 1 illustrated primary circuit 52 of the centrifuge 10 from the perspective of the secondary circuit 62 is shown.
  • the compressor 22, the condenser 24 with the associated fan 25, the filter dryer 28 and the evaporator 26, not shown here are connected to one another via primary pipelines 29.

  • the rigid foam molded part 40 extends horizontally between the side walls 13b and 13c along the housing cover 13a and vertically in some areas along the side walls 13b and 13c and in some areas along the profile of the aforementioned elements of the primary circuit 52.
  • the vertical extent of the rigid foam molded part 40 is adapted to the structural conditions of the Adjusted primary circuit and chosen so that it is easy to introduce and surrounds about the upper third of the compressor 22 and at the same time at least on the top of said elements of the primary circuit 52 is present.
