Description
Technical field
The utility model relates to a kind of aseptic agitator, relates in particular to the aseptic agitator of a kind of high-temperature superconducting magnetic levitation.
Background technology
Aseptic agitator is usually used in pharmaceuticals industry, chemical experiment etc. to the harsh situation of environmental requirement, and it requires the stirring clean environment, aseptic of agitator, in order to avoid pollute the liquid that is stirred.Existing agitator comprises the impeller that is provided with the band rotating shaft in the housing, housing of sealing, impeller shaft stretches out outside the housing and links to each other with motor shaft, for fixed rotating shaft and make rotating shaft pass the sealing of locating of housing, the position that impeller shaft stretches out housing adopts mechanical bearing to fix and seal.The sealing effectiveness of mechanical bearing is not fine, and cleans difficulty.In whipping process, along with stirring, the rotation of liquid, stir thing and very easily contact with mechanical bearing, it is contaminated easily to stir thing, makes to be stirred thing and to discard, and causes damage.
The utility model content
The purpose of this utility model just provides the aseptic agitator of a kind of high-temperature superconducting magnetic levitation, the aseptic agitator of this high-temperature superconducting magnetic levitation has been realized the contactless transmission between motor shaft and the impeller shaft, have free of contamination advantage, be particularly suitable for aseptic strict occasion.
The utility model is realized its goal of the invention, and the technical scheme that is adopted is: the aseptic agitator of a kind of high-temperature superconducting magnetic levitation, and its design feature is:
The housing of agitator is provided with the high-temperature superconductor transmission device, specifically the constituting of high-temperature superconductor transmission device: the last permanent magnet of housing top links to each other with motor rotary shaft; Case top fixed-site under the last permanent magnet has low-temperature (low temperature) vessel, and low-temperature (low temperature) vessel is built-in with high-temperature superconducting block; Following permanent magnet is arranged in the housing under the low-temperature (low temperature) vessel, and the bottom of following permanent magnet links to each other with impeller shaft.
The middle part of impeller shaft is connected with impeller; The bottom of impeller shaft is connected with the Permanent-magnet bearing of housing inner bottom part.
The course of work of the present utility model and operation principle are:
During work, in low-temperature (low temperature) vessel, fill with liquid nitrogen, utilize the pinning characteristic of high-temperature superconducting block that the magnetic flux line that upper and lower permanent magnet produces is pinned on the high-temperature superconducting block, upper and lower permanent magnet and high-temperature superconducting block " coupling " are arrived together, permanent magnet and low-temperature (low temperature) vessel disengage in the maintenance, high-temperature superconducting block floats in the liquid nitrogen, and following permanent magnet swims in the air.Because last permanent magnet and motor shaft link, the last permanent magnet that drives housing (outside) top when motor rotates rotates, last permanent magnet rotates by the following permanent magnet that pinning effect drives high temperature bulk and housing inner top, realize that housing inside and outside " contactless " rotates conduction, impeller shaft and impeller that the following permanent magnet in the housing drives bottom in the housing that is attached thereto again rotate together.Simultaneously, because the Permanent-magnet bearing that install the impeller bottom impeller shaft is realized axial support and radially stable, so impeller can be realized the stable rotation of not having skew.
Compared with prior art, the invention has the beneficial effects as follows:
Because motor shaft that housing is outer and the rotation transmission between the impeller shaft in the housing are a kind of " contactless " transmissions, have cancelled and have passed the mechanical bearing that housing plays the connection effect, the sealing property of agitator housing improves greatly.In whipping process, the pollution that does not exist mechanical bearing to occur has guaranteed the strict aseptic of whipping process, is particularly suitable for aseptic strict operation.
Above-mentioned last permanent magnet and following permanent magnet are made of the multilayer magnet ring of ring-type, and every ring permanent magnet is vertical direction and magnetizes, and the magnetizing direction of adjacent magnet ring is opposite, and the last permanent magnet of same ring is identical with the magnetizing direction of following permanent magnet.
The gap that the upper and lower permanent magnet of this structure can make the magnetic line of force concentrate on upper and lower permanent magnet most that is to say in the superconduction block material, also can guarantee the not occurred level dislocation of upper and lower permanent magnet simultaneously.Thereby the pinning effect that produces is the strongest.
Above-mentioned Permanent-magnet bearing is to be made of inside and outside magnet ring, and the permanent magnet that inside and outside magnet ring is vertical multilayer constitutes, and permanent magnet is vertical to magnetize, and the magnetizing direction of adjacent layer is opposite.
The Permanent-magnet bearing of this structure can guarantee that the magnetic line of force concentrates on the running clearance place of bearing more, and it realizes that axial support and radially stable effect are better.
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail.
