Definitions
- a magnetic stirrer for stirring low viscosit media comprises a plurality of stationary electromagnets ar ranged in a housing on which a-receptacle containing th medium to be stirred can be mounted.
- the receptacle als contains one or more freely movable stirring arms controlle by the electromagnets which produce a rotary magnetic fielt by corresponding consecutive energization of the individua electromagnets by means of an electronic control element.
- PATENIEnJAmzlsm 34554497 sum 2 or 2 ELECTRONICALLY CONTROLLED MAGNETIC STIRRER
- the invention relates to an electronically controlled magnetic stirrer for stirring media of low viscosity, wherein a rotating magnet which performs the stirring work is disposed in a housing, on which there is mounted a vessel container the medium to be stirred, there being freely movably disposed in the said vessel one or more stirring members which are driven by the rotating magnet and which stir the medium.
- the stirring members in the vessel are driven by the rotating magnet lines of force pass through the vessel, the latter may consist of a material of any kind with the exception of a magnetic material.
- Such apparatus are employed primarily in chemical laboratories, so that the media to be stirred are primarily chemicals, and the stirring members are therefore preferably provided with an acid-resistant coating.
- the object of the present invention is to provide a magnetic stirrer, wherein the field strength which acts on the stirring member and the speed of the later can be infinitely varied, and which has no mechanically or electrically moved parts and consequently requires no servicing and, in addition, has from the outset the properties of an explosion-proof apparatus.
- Apparatus are already known in which 'a permanent magnet is rotated in some way within the housing during the operation.
- This permanent magnet transmits its rotational movement, by means of the magnetic field transmission, to a second permanent magnet situated in the stirring vessel, i.e. to the stirring member. ln such cases, it is immaterial whether the permanent magnet in the housing of the stirrer is directly mounted on the shaft of the electric motor or is mounted on a shaft driven through a transmission system.
- the first stator and the rotor associated therewith form the driving motor
- the second stator is the rotating permanent magnet
- the second rotor is the stirring member consisting of a permanent magnet and situated in the vessel.
- stirring apparatus which employ an electric rotating-field generator within the housing.
- Such apparatus operate only at a supply frequency of S c/s or 60 CIS and they therefore have no means for speed regulation.
- the invention has for its object to provide an apparatus based upon a very simple principle and having no mechanically moving parts, which constitutes further development of the existing known apparatus, i.e. the apparatus is to operate silently, to be infinitely regulatable in speed and magnetic field strength, to have no wear and to be explosionproof.
- this object is achieved in an apparatus of the type mentioned at the beginning, by virtue of the fact that there are employed to drive the stirring member or members, instead of a rotating magnet, one or more fixed electromagnets disposed in the housing, which generate a rotating magnetic field, the speed of the magnetic field, by which the stirring frequency-is determined, and the strength of the said field being infinitely variable within a wide range of limits by an electronic control element for feeding the electromagnets.
- the electromagnets generate a rotating electromagnetic field, which in turn transmits this rotational movement to the stirring member situated in the stirring vessel and this initiates and maintains the stirring operation.
- the apparatus according to the invention requires only one stator and one rotor.
- ln consists of a fixedly mounted electromagnet within the housing constituting a stator and a soft-iron or permanent magnet, freely movable in the stirring vessel, constituting a rotor.
- the intensity of the rotating magnetic field which is generated by the electromagnet makes it possible in accordance with the invention, to employ as stirring members in the vessel containing the medium to be stirred magnetizable soft-iron parts which are provided with blades or the like which promote the stirring action.
- the advantages achieved by the invention consist mo especially in that, with low cost of construction, an apparat can be produced which employs no mechanically or elect cally movable parts and thus has an unlimited useful life, a1 which operates silently and is explosionproof, since sparkir for example due to an electric motor, need not be given co cem.
- the speed of rotation of the magnetic fie and thus the speed and the magnetic field strength may regulated and thus adapted to the particular purpose of us
- a soft-iron or p: manently magnetic plate which is in turn intended to recei a vessel and whichperforms a three-dimensional agitati movement with the vessel under the influence of the rotati magnetic field, whereby a further possibility of application the apparatus is afforded.
