Title: Fluidizing device for solid particulates

Abstract

A flexible whip suspended in a hopper is caused to impact against fibrous and irregularly shaped particulates in the hopper to fluidize the particulates and facilitate the flow of the particulates through the hopper. The invention provides for the flow of particulates at a substantially constant mass flow rate and uses a minimum of energy.

  • A flexible whip or a system of whips with novel attachments is suspended in a hopper and is caused to impact against fibrous and irregularly shaped particulates in the hopper to fluidize the particulates and facilitate the flow of the particulates through the hopper. The invention provides for the flow of particulates at a substantially constant mass flow rate and uses a minimum of energy.

  • An apparatus is described for facilitating a flow of solid particulates through an orifice of a hopper comprising: (a) a flexible whip including two transversely spaced elongated members, the two elongated members being connected to one another at opposed ends thereof; (b) means for mounting the whip in a generally vertical orientation within the hopper such that one end of the whip is freely suspended above the orifice; (c) means for causing the whip to rotate about a substantially vertical axis defined by the hopper such that each one of the two elongated members are caused to independently impact andmore » fluidize the solid particulates within the hopper, and wherein an anchor is affixed to the freely suspended end of the whip, and wherein the anchor comprises: (i) a rigid longitudinal member having a first and a second end, the first end being connected to the freely suspended end of the whip; and (ii) a spiral member which is supportedly connected to the second end of the longitudinal member.« less
  • The invention provides a method for dispersing particles within a reaction field, the method comprising confining the particles to the reaction field using a standing wave. The invention also provides a system for coating particles, the system comprising a reaction zone; a means for producing fluidized particles within the reaction zone; a fluid to produce a standing wave within the reaction zone; and a means for introducing coating moieties to the reaction zone. The invention also provides a method for coating particles, the method comprising fluidizing the particles, subjecting the particles to a standing wave; and contacting the subjected particlesmore » with a coating moiety.« less
