Definitions

  • the present invention relates to a simpler and more compact support and guide means for a stripping knife.
  • a guiding part is provided which, on the one hand, is displaceably guided relatively to the knife support along a first straight line and which, on the other hand, is displaceably guided relatively to the housing along a second straight line, the straight lines having directions. which differ from one another and lying in one plane or each lying in a different plane, the different planes being perpendicular to the axis of the knife carrier.
  • FIG. 1 is a longitudinal section through one constructional form of a stripping centrifuge according to the invention, given as an example,
  • FIG. 2 is a section on an enlarged scale along the line Il-II in FIG. 1 for showing the guide arrangement of the stripping knife
  • FIG. 3 is a section along the line IIIIII of FIG. 2,
  • FIG. 4 is a section similar to FIG. 2 for showing a second example of the guiding arrangement for the strip- I ping knife
  • the stripping centrifuge whichis shown in FIG. 1, 2 and 3 comprises a housing 2 which is provided with a housing cover 1 and within which a centrifuge drum 3 is rotatably arranged. Disposed inside the centrifuge 2 drum 3 is a knife carrier 5 which has a stripping knife 6, which extends over the entire internal width of the centrifuge drum 3.
  • the holding part 4 is mounted on the housing 2 and is rotatable about axis 8 (See FIG. 3). This axis 8 extends parallel to the axis 7 of the centrifuge drum.
  • the carrier shaft 9 of the knife carrier 5 is mounted eccentrically in the holding part 4 and is impositively connected through a connecting part 10 rigidly connected to it to a guiding part 12 which includes first guide means for displacement along a guide rod 11 extending at right-angles to the carrier shaft 9 and in the direction of displacement of the said part 12.
  • the connecting part 10 is in its turn displaceably connected to the guiding part 12 through the second guide means or bush 13 along a straight line 14 extending at rightangles to the carrier shaft 9.
  • the guiding part 12 is connected to a doubleacting servomotor 15, as will be seen from FIG. 1.
  • the holding part 4 has a cylindrical external surface, it can in a simple manner be rotatably mounted in the centrifuge housing and sealed off.
  • the servomotor 15 can be connected, for example, to the holding part 4 instead of to the guiding part 12. See FIG. 4.
  • FIG. 4 is a section similar to FIG. 2 also illustrating another example of a constructional form of the guiding arrangement for the stripping knife.
  • the connecting part 10' is connected rigidly to the guiding part 12 and is extended in a displaceable manner through a guide bush 13' connected fast to the carrier shaft 9.
  • the other parts are constructed in the same way as with the constructional example shown in FIG. 1 to 3.
  • the carrier shaft 19 is constructed as a hollow sleeve, as shown in FIG. 5, and the knife carrier 5 is connected to a knife shaft 16 which is guided to be axially displaceable but nonrotatable relatively to the hollow shaft
  • the guide arrangement of the stripping knife can also be used for a stripping knife 6 which is displaceable axially in the drum 3.
  • the servomotor 17 for the displacement of the stripping knife 6 can then be connected, on the one hand, to the knife shaft 16 and,
  • the servomotor may be connected to the rotary holding part 4 rather than to the sleeve 19.
  • the guiding part 12 for the guiding action along the secondstraight line (in the vertical direction) is rigidly connected to a guide rod 11, which is in its turn displaceably guided in the housing 1.
  • the guide .rod 11 is connected to a piston of a doubleacting servomotor 20 and forms the piston rod of the servomotor 20.
  • a centrifuge 1 comprising a housing 2, a drum 3, rotatable mounted in said housing 2, and a stripping knife 6 arranged in said drum; a knife carrier carrying said stripping knife; said knife carrier including a shaft; a holding part 4 in which said shaft is joumalled; said holding part being mounted to rotate on said housing; the axis ofsaid shaft and the axis of rotation 8 of said holding part being parallel to, and apart from each other, said axis being parallel with the axis of rotation of the drum; a guiding part 12, 12 reacting between said housing and said knife carrier; first guide means 10 to guide said guiding part so that the guiding part is translatorily displaceable relatively to said knife carrier along a first straight line; and second guide means 11, 11' to guide said guiding part so the guiding part is translatorily displaceable relatively to said housing along a second straight line; said straight lines having directions which differ from each other; each of said straight lines lying in a plane extending at right-angles to said shaft.
  • said second guide means comprises a bore in said guiding part; and a guide rod rigidly connected to said housing, guided in said bore.
  • said second guide means comprises a guide rod 11 rigidly connected to said guiding part 12 said rod being guided by said housing.
