Definitions

  • Thi invention relates to a centrifugal machine of the type wherein the wall of the drum is provided with a passage, or with passages, through which a heating or a cooling liquid is adapted to flow under the action of the centrifugal force.
  • the invention has for its purpose to render the rate, at which the liqu d flows through said passages, controllabl and to allow the liquid still present therein after the charge has been subjected to centrifugal treatment during the required time, to be discharged as' the speed of the drum decreases.
  • the drum is provided with a jacketed bottom and with a jacketed top, both communicating with the passages and both extending inward to a suitable distance from the axis, a stationary supply and skimming pipe being provided so as to open into the bottom jacket.
  • FIG. 1 is a vertical sectional elevation
  • Fig. 2 a fragmentary section on the line IIII in Fig. 1.
  • the material to be treated is supplied through a pipe 3 centrally into the drum or bowl 4.
  • the peripheral wall of the drum is formed by a circular series of axially disposed and suitably spaced straight pipes 5, interconnected by perforated webs 6, the smooth inner face of said wall being lined by wire gauze 1.
  • the drum has a jacketed bottom 8 communicating with the lower ends of the pipes 5. Opening into said jacket is a stationary pipe 9. whose mouth extends radially outwards and which is connected, through a threeway cock Ill, to a pipe I l for supplying, and to a pipe ii! for discharging a heating or a cooling liquid.
  • a pipe I l for supplying, and to a pipe ii! for discharging a heating or a cooling liquid.
  • radial partitions l3 intermediate the bottom openings of the pipes 5.
  • the pipes communicate with an annular, jacketed top I 4, which communicates, along its inner edge, with an annular chamber l5 provided with a discharge nozzle Hi.
  • the described centrifuge operates as follows.
  • the cock I'll is set to establish communication between the pipes 9 and I2 and the speed of the drum 4 is reduced, so that the liquid still present in pipes 5 is allowed to gradually sink and be skimmed off by the pipe 9.
  • a drum having a passage in the peripheral wall thereof, a jacketed top on said drum and a jacketed bottom on said drum, the said jacketed portions of said drum extending inwardly and having openings therein communicating with said passage in said wall, means for introducing a fluid to said jacketed portions and said passage, and a skimming and discharge pipe introduced in said jacketed bottom whereby said liquid may be removed from said bottom.
  • a drum having a passage in the peripheral wall thereof, a top member on said drum having spaced portions thereof defining a compartment, a bottom member on said drum having spaced portions thereof defining a compartment said compartments extending inwardly and having openings therein communicating with said passage in said wall, means for introducing a fluid to said compartments and said passage, and a skimming and discharge pipe entering said bottom compartment whereby said liquid may be removed from said compartment.
  • the said peripheral wall of said drum comprising a circular series of axially disposed pipes interconnected by perforated webs and the inner face of said wall having a wire gauze lining, said pipes having openings in the ends thereof communicating with said openings in said top and bottom compartments, the said bottom compartment having radial partitions intermediate said openings in said axially disposed pipes thereby forming a passage for said fluid.
