Claims
- 1. In an apparatus for degassification of liquids having a rotatable body for receiving a liquid mounted around a fixed shaft having an internal passage for introducing the liquid into the body and associated with an annular chamber for collecting the liquid,
- the novel combination of improvements in degassification of liquid suspensions and emulsions at reduced pressure being,
- a rotatable body consisting of a frustum of a cone which is defined at a first end by a first base plane surface intersecting the axis of the body and at the opposite and second end by a second plane surface intersecting the axis of the body and of a lesser area than said first base plane surface,
- said rotatable body being mounted around a fixed axially extending shaft,
- and enclosing an interior of the body of progressively increasing diameter from the second plane surface to the first base plane surface and having an internal wall surface adapted to receive the liquid radially injectable to the wall surface from the shaft under reduced pressure,
- a passage in the shaft positioned at the second end of the body and adapted to introduce the liquid via said passage into the rotatable body,
- means positioned adjacent the second plane surface for the passage of the liquid from the passage in said shaft to the internal wall surface,
- including means to apply the liquid onto a surface which rotates and for effecting a change of pressure on the liquid within a limited period of time to at least partially degassify the liquid, in passing to the internal wall surface, said means consisting of a sharp edged shutter adapted to restrict the liquid to be degassed,
- said body and fixed shaft being so constructed and arranged that the liquid is receive on the internal wall surface of the rotatable body and the body is adapted to spread the liquid out under a reduced pressure so that the liquid forming a thin film on the internal surface under the influence of the centrifugal force may become even thinner on the internal wall surface and is degassed,
- and being adapted to move the liquid under centrifugal force radially and axially along the internal wall surface at an acceleratable rate to an annular collecting chamber for collecting degassed liquid from the wall surface adjacent the first base plane surface,
- and associated with said collecting chamber, recessed means extending into the collecting chamber for removing the degassed liquid,
- whereby degassed liquid is drawn out of the apparatus against the reduced pressure in the body interior.
