Abstract
A vacuum centrifuge has a cylindrical centrifuge housing forming a vacuum chamber and a cylindrical centrifuge pot is coaxial with the vacuum chamber. An elongated hollow shaft extends externally and coaxially from the cylindrical centrifuge pot and forms a passage for an elongated thread carrier tube extending into the pot. At least one magnetic bearing and a motor surround the elongated hollow shaft. An annular wall connects a terminal end of the elongated hollow shaft to the cylindrical centrifuge pot and forms a boundary surface within the vacuum chamber in which the centrifuge pot is located.
Claims7
A vacuum centrifuge having an elongated thread carrier tube, a cylindrical centrifuge housing forming a vacuum chamber and a cylindrical centrifuge pot coaxial with said elongated thread carrier tube, said cylindrical centrifuge housing and said cylindrical centrifuge pot have a diameter greater than the diameter of said elongated thread carrier tube and said cylindrical centrifuge pot having a smaller diameter portion forming a hollow shaft having a diameter less than the rest of the centrifuge pot and coaxial with and surrounding a longitudinal portion of said elongated thread carrier tube, and at least one of a magnetic bearing and a motor surrounding said smaller diameter portion of said cylindrical centrifuge pot, wherein said cylindrical centrifuge pot has a base part which includes an elongated coaxial external auxiliary shaft, at least one other magnetic bearing surrounding said elongated auxiliary shaft which acts on it and a seal surrounding said hollow shaft.
A vacuum centrifuge having an elongated thread carrier tube, a cylindrical centrifuge housing forming a vacuum chamber and a cylindrical centrifuge pot coaxial with said elongated thread carrier tube, said cylindrical centrifuge pot having an elongated hollow shaft extending externally and coaxially therefrom, said elongated hollow shaft forming a passage for said elongated thread carrier tube, at least one magnetic bearing surrounding said elongated hollow shaft, a motor surrounding said elongated hollow shaft, and an annular wall connecting a terminal end of said elongated hollow shaft to said cylindrical centrifuge pot and forming a boundary surface between said vacuum chamber and the interior of said cylindrical centrifuge pot, wherein said cylindrical centrifuge pot has a base part which includes an elongated coaxial external auxiliary shaft, and at least one other magnetic bearing surrounding said auxiliary shaft and a seal surrounding said hollow shaft.
A vacuum centrifuge having an elongated thread carrier tube, a cylindrical centrifuge housing forming a vacuum chamber and a cylindrical centrifuge pot coaxial with said elongated thread carrier tube, said cylindrical centrifuge pot having an elongated hollow shaft extending externally and coaxially therefrom, said elongated hollow shaft forming a passage for said elongated thread carrier tube, at least one magnetic bearing surrounding said elongated hollow shaft, a motor surrounding said elongated hollow shaft, and an annular wall connecting a terminal end of said elongated hollow shaft to said cylindrical centrifuge pot and forming a boundary surface between said vacuum chamber and the interior of said cylindrical centrifuge pot, wherein a substantial portion of the length of said elongated hollow shaft is located within said vacuum chamber, wherein said cylindrical centrifuge pot has a base part which includes an elongated coaxial external auxiliary shaft, at least one other magnetic bearing surrounding said auxiliary shaft and a seal surrounding said hollow shaft.
