초록 ▼

The present invention utilizes high magnetic flux materials to substantially increase the power which can be transmitted from a magnetic driver, disposed outside of a vessel containing a fluid being processed, to a magnetically responsive agitator means disposed inside the vessel. This invention now enables the agitation, e.g., mixing, blending, etc., of fluids processed in the pharmaceutical, chemical and food processing industries, where relatively high torques are encountered, by non-contaminating magnetic drive means heretofore precluded in such applications. Means for producing vibrational agitation, and for reducing wear of the internal agitator bearing are also disclosed.

대표청구항 ▼

In an apparatus for agitating a fluid contained in a vessel comprising (i) a driver member rotatably coupled to a drive means and having affixed therein a first plurality of permanent magnetic members; (ii) a driven member rotatably mounted within said vessel coaxially with the axis of rotation of said driver member, and having affixed therein a second plurality of permanent magnetic members; (iii) said magnetic members each being made of material characterized by high energy products; (iv) said first and second pluralities of magnetic members being disposed in corresponding symmetrical arrays within said driver and driven members respectively, the magnetic poling of said magnetic members alternating between magnetic north and magnetic south poles; and (v) impeller means fixedly secured to said driven member, improved means for supporting said drive means and driven member external to said vessel and said driven member internal to said vessel, comprising: (a) a vessel plate fixedly secured in said vessel, said vessel plate having affixed on the face thereof internal to said vessel a bearing means, and on said face thereof external to said vessel a flange means extending therefrom; (b) an adapter plate arranged and configured to engage said flange means; (c) a spacer means disposed between said adapter plate and a housing of said drive means; (d) means for fixedly securing said adapter plate to said drive means housing through said spacer means; and (e) clamp means for removably affixing said adapter plate to said flange means of said vessel plate; whereby said drive means is suspended from said vessel and said driven member is rotatably supported by said bearing means, and torque from said drive means is transmitted from said driver member to said driven member by the magnetic forces existing between said first and second pluralities of magnetic members, causing said driven member to rotate in unison with the rotation of said driver member, and said impeller means to agitate said fluid.
