39635139, Jun 15, 1976

Filed:

Oct 21, 1974

Appl. No.:

5/516341

Inventors:

John A. Casey - San Francisco CA

International Classification:

C13D 302
B01F 500

US Classification:

127 11

Abstract:

Method and apparatus for controlled growth of precipitates in systems requiring separation of undesirable contaminants from a solution prior to treatment with a coagulant aid. Cane sugar juice, as exemplary, is introduced at an elevated temperature into an apparatus having means for maintaining a mildly reduced pressure. The apparatus has a conical funnel with a downwardly extending tubular outlet. Means are provided for incrementally and continuously introducing a chemical treating agent into the juice, as it flows down the funnel toward the outlet. Juice discharge means allows for control of the retention time in the tower. The method of treating cane sugar juice is as follows. Cane sugar juice, preferably partially limed, is introduced into the top of the funnel at an elevated temperature and allowed to flow by gravity flow through the funnel, while additional milk of lime is incrementally and continuously introduced into the cane sugar. The cane sugar juice flows downwardly through an outlet and then upwardly to allow for controlled formation of insoluble precipitate particles.

Abstract:

A method and apparatus for enhancing growth of precipitates in systems requiring separation of undesirable contaminants. Cane sugar juice, as exemplary, is introduced at an elevated temperature into an apparatus having means for separately introducing chemical treating agents, such as milk of lime and coagulants. The juice flows through a treating zone where the agents are introduced, into a holding zone and over a dispersion cone before being withdrawn from the holding zone by a siphoning means. The dispersion cone and holding zone bottom permit rapid growth of the insoluble particles while simultaneously diverting the flow direction gently so as to prevent breakup of the particles. The flow down through the treating zone, over the dispersion cone, down the conical holding zone bottom, and back up the siphoning means permits sufficient residence time for rapid growth of the insoluble particles so that coagulants need not be added in the subsequent clarification process. A mild vacuum may be maintained within the apparatus for enhancing deaeration of the solution.

Abstract:

A mill roll includes a roll body, a plurality of circumferentially extending grooves formed in the periphery of the roll body, a plurality of channels extending axially through the roll body at positions inwardly of the grooves, a plurality of inserts fitted within the roll body at the radial bottoms of the grooves, and each insert having extending substantially radially therethrough an opening connecting the respective groove with a respective channel. Each opening has an elongated, substantially rectangular circumferential cross-section with a longer dimension extending substantially circumferentially of the roll body and a narrower dimension extending axially of the roll body.

International Classification:

B01D 2101

US Classification:

210715

Abstract:

A solid-liquid slurry, particularly sugar juice, is flocculated and clarified in an arrangement including a clarifier tank containing therein a mud bed of concentrated removed solids. A preflocculating vessel extends into the top of the clarifier tank and includes upper and lower chambers. The slurry is introduced into the upper chamber to flow turbulently therein, thereby deaerating the slurry. The slurry is transferred from the upper chamber to the lower chamber while the turbulent flow of the slurry is changed to a laminar flow. A flocculating agent, for example a suitable polymer, is introduced into the slurry, such that solids of the slurry coagulate as flocs in the lower chamber. The thus preflocculated slurry is introduced directly into the clarifier tank at a level beneath the surface of the mud bed therein. The liquid of the slurry percolates upwardly through the mud bed and is filtered, thus forming clarified liquid, and the flocs of solids settle downwardly into and form the mud bed.

Abstract:

An electronic kiosk receives a plurality of messages. The kiosk has a transceiver to utilize a set of radio communication technologies to detect and establish a radio communication link with a mobile computing device when the mobile computing device is located within proximity of the electronic kiosk. An application specific software program executes on a processor in the kiosk to provide as output one or more of the received plurality of messages depending on the location of the mobile computing device within the proximity of the electronic kiosk.
