Definitions
- the invention relates to a centrifuge according to the specified in the preamble of claim 1. Art.
- Compressor cooling devices are particularly often used for this purpose. Although this type of cooling is proven and reliable, it also has a number of disadvantages. On the one hand, due to the use of compressed media for heat extraction, it is necessary to use conduit means such as copper pipes which can withstand high pressures in a range of about 25 bar. Copper pipes are not only expensive to buy, but due to their rigidity, they can only be installed at certain points of a centrifuge and offer a comparatively small heat-transferring area. On the other hand, the temperature control is usually in the form of a two-point control, ie by switching the compressor on and off. The more accurate the temperature is to be set, the more frequently switching on and off is required.
- the object of the present invention is to provide, while avoiding the disadvantages mentioned, a centrifuge whose cooling is efficient and inexpensive, which is low vibration during operation and thus gentle on the material to be centrifuged and which is harmless under safety aspects.
- the invention is based on the finding that conventional cooling devices for centrifuges, in particular compression refrigeration devices, can be replaced by a magnetocaloric cooling and so that in a simple manner a centrifuge can be created whose operation is safer, more economical and gentler than the operation of conventional centrifuges. In addition, this results in a number of new design options that further optimize the centrifuge.
- the centrifuge comprises a safety boiler with a boiler wall, a rotor arranged in the safety boiler, which is connected via a drive shaft to a drive device, at least the drive shaft passing through the safety boiler, and a cooling system for cooling the interior of the safety boiler, a heat transfer medium for
- Heat absorption from the safety boiler, a refrigeration unit and conduit means for the heat transfer medium comprises.
- the refrigeration unit is based on the magnetocaloric effect.
- the interior of the safety boiler is cooled by a first cooling circuit.
- the magnetocaloric effect of the refrigeration unit extracts heat from the heat transfer medium of the first cooling circuit and supplies it to a second cooling circuit.
- the refrigeration unit contains magnetocaloric material which heats up when exposed to a magnetic field and cools again when the magnetic field is removed. By cyclic loading of this magnetocaloric material with a magnetic field and flow around this material from a heat transfer medium of the second cooling circuit, this heat is withdrawn, and in flowing around with a heat transfer medium of the first Cooling circuit to which the heat is released, a heat transfer process is underway.
- cooling water with additives which reduce the freezing point for example salt or alcohol, is used as the heat transfer medium.
- additives which reduce the freezing point for example salt or alcohol
- the conduit means for the heat transfer medium are designed as low-pressure lines for an operating pressure of less than 3bar.
- the design possibilities of the design of the conduit means are easily expanded.
- flexible materials that can be better adapted to the surfaces to be cooled and thereby enable more efficient cooling.
- the flexible materials are usually also lighter and cheaper than the materials used for high pressure lines, such as copper.
- a control or regulation unit is provided, by means of which the cooling unit can be controlled or regulated, and thus the temperature in the interior of the safety boiler is adjustable. This ensures that, depending on the application and operating condition in the centrifuge, an optimal, predetermined temperature prevails and is maintained.
- pumps are provided in each circuit. It is advantageous if the pumps can also be controlled or regulated by the control or regulation unit. This allows the temperature in the centrifuge in addition over quantity and speed of the conveyed heat transfer medium can be adjusted by the conduit means.
- the safety boiler has an inner side directed towards the rotor and an outer side cooperating with the cooling system, and the conduit means of the first cooling circuit are at least partially formed by the safety boiler, so that the heat transfer medium on the outside of the boiler wall of the safety boiler immediately lies flat and flows over it.
- the heat transfer medium is guided by the conduit means partially parallel and / or radially to the central axis of the safety boiler.
- the structural conditions of the centrifuge can be taken into account and a larger area of the boiler wall can be cooled.
- the safety boiler is double-walled with an inner wall and an outer wall.
- the heat transfer medium flows between the inner wall and the outer wall, wherein it rests directly on the outside of the inner wall of the safety boiler and flows over it.
- an approximately full-surface cooling of the inner wall of the safety boiler can take place, while the outer wall may have insulation, for example.
- the inner wall forms an inner shell and the outer wall forms an outer shell, whereby the inner shell and the outer shell are arranged concentrically with each other, whereby the inner shell and the outer shell are proportional to each other are coordinated that arise in areas uniform distances between the inner wall and outer wall.
- This facilitates the manufacture of the safety boiler and allows a uniform flow of the heat transfer medium between the inner wall and the outer wall.
- it is beneficial if between the inner wall and the outer wall
- Conductive means are.
- conduit means are provided which are incorporated in the material of the boiler wall of the safety boiler.
- the outer side of the inner wall and the inner side of the outer wall have mutually associated recesses in the wall, which together form the conduit means, ie the cooling line of the safety boiler. This eliminates the need to build your own components for the lines in the wall of the safety boiler, and the production of the safety boiler is easier and cheaper.
- an inlet of the heat transfer medium to the conduit means of the safety boiler and a drain of the heat transfer medium are provided and if either the inlet is located in the region of the upper edge of the safety boiler and the drain is located in the region of a boiler bottom of the safety boiler or vice versa ,
- the heat transfer medium considered vertically, be introduced on one side of the safety boiler and removed on the other side of the safety boiler after the heat removal.
- annular, preferably extending in a plane, distribution channel connects to the inlet.
- annular, preferably running in a plane, collecting channel is connected upstream of the sequence.
- This construction simplifies the removal of the heat transfer medium after flowing through the wall.
- the boiler wall is an aluminum part produced by die-casting. Also suitable here is zinc.
- U-shaped line profiles are placed on the outside of the boiler wall, which form the conduit means of the safety boiler.
- the U-shape of the boiler wall is completed, so that the two legs are directed in cross-section of the pipe profile against the boiler wall.
- a centrifuge lid is provided, introduced into the conduit means connected to the refrigeration unit or applied to the conduit means connected to the refrigeration unit.
- the heat transfer medium can also be used for efficient cooling of the
- Centrifuge lid can be used.
- the drive device is at least partially from
- the drive device which is a cause of a strong heat input into the safety boiler, directly cooled.
- the area of the drive device surrounded by line means projects into the safety boiler.
- the cooling is technically easy to implement, for example, by a cover provided with line means, which is placed on the projecting into the safety boiler area of the drive device and secured there.
- the cooling effect acts both on the drive device and on the interior of the safety boiler.
- conduction means for the heat transfer medium connected to the refrigeration unit are integrated into the drive device. This type of cooling is efficient and especially space-saving.
- the safety boiler is designed as a deep-drawn sheet steel boiler made of steel, especially stainless steel. This reduces the manufacturing costs and is useful for the longevity of the safety boiler.
