BRIEF DESCRIPTION OF THE DRAWINGS While the specification concludes with claims particularly pointing out and distinctly claiming the subject matter regarded as forming the present invention, it is believed that the present invention will be better understood from the following description taken in connection with the accompanying drawings in which:
FIG. 1 is a sectional plan view of the deaerator of this invention;
FIG. 2 is a fragmentary sectional elevation of the deaerator taken along the line 2-2 in FIG. 1; and
FIG. 3 is a sectional elevation view of a deaerator having a rotor with multiple perpendicular flanges.
SUMMARY OF THE INVENTION The present invention relates to a centrifugal vacuum deaerator comprising a rotor which comprises a flange positioned to receive the material to be deaerated after it is accelerated by centrifugal force, said flange being distinguished by being unperforated in the area where the material impinges, and said flange being further distinguished by the absence of any flow-impeding 11 and maintain said vacuum. The primary reason for the vacuum inside chamber 11 is to avoid retrapping air. Inlet means 12 are provided whereby the product to be deaerated can be introduced into the vacuum chamber 11. v
The rotor also comprises a flange 17 which inFIG. 1
is a tapered straight flange which receives the material to be deaerated as it is accelerated through the: holes 16. When the material to be deaerated impinges on the flange 17, it is moved by centrifugal force down the flange, around the braces 18 which hold the flange 17 in proper position with respect to the shaft 14, to the bottom edge of the flange 17 where centrifugal force again accelerates the material to be deaerated, thereby throwing it against the side of the chamber 11 from whence it falls by gravity to the bottom of chamber 11. The deaerated material can be removed in any convenient manner, e.g., continuously removed through a means which would impede the spreading of said material into a thin film when it is deposited on said flange and the presence of an edge on said flange over which said thin film of said material can be sheared by centrifugal force.
DETAILED DESCRIPTION OF THE INVENTION hole (not shown) at the bottom of the chamber 11. It will be evident from FIG. 3 that a similar mode of operation is envisioned for this embodiment which simply provides multiple flanges. In FIG. 3, like reference numerals denote similar structural aspects to those of the apparatus of FIG. 1.
The process of this invention is distinguished by making use of centrifugal force to create a thin film which is then sheared over an edge which is preferably sharp, but which can also be rounded. The preferred embodiment of the process of this invention also includes a step in which the fluid to be deaerated is thrown through holes by centrifugal force. This step gets rid of the largest bubbles. The material then impinges against the flange where it is spread into a very thin film which permits the escape of small bubbles, and finally, when the thin film of the viscous liquid reaches the edge of the flange, it is sheared which elongates and ruptures the walls of even smaller bubbles.
The rotor speed can be varied widely depending upon the strength of the materials used in the fabrication of the deaerator. Rotor speeds of from about 500 to about 10,000 RPM can be used. Slower rotor speeds will normally be used with larger rotors, for example, rotors having an OD of about two feet, and faster rotor speeds will normally be used with smaller rotors, i.e., those with an OD of about one-half of a foot.
As previously indicated and as shown in FIG. 3, a series of flanges provides even greater deaeration.
The advantages of the process of the present invention include simplicity, economy and ease of maintenance, especially cleaning. The process also deaerates well at low vacuums (10-20 in. of Hg) which decreases the loss of volatile material from the viscous liquid. The process can be used over a wide temperature range and can be either a batch or continuous process.
