초록 ▼

An apparatus for continuous sulfonization of discrete articles comprising a feeder box for drying the discrete articles with ultra-dry air, a sulfonization chamber for treating the discrete articles with sulfur trioxide gas, a conveyor assembly for transporting the discrete articles from the feeder box to the sulfonization chamber, and a neutralizing tank for treating the discrete articles with neutralizing fluid. The sulfonization chamber includes a rotating dial plate with a circular periphery and an upper surface extending radially from and rotatable about a center axis (A) for receiving the discrete articles at the circular periphery. A plurality of arcuate guides extend perpendicularly from a guide arm toward the rotating dial plate and are spaced radially outward from one another along a radial (R) extending radially from the center axis (A) for moving the discrete articles radially inward in a spiral path during rotation of the rotating dial plate.

1. A method for continuous sulfonization of discrete articles including a feeder box for drying the discrete articles with ultra-dry air, a sulfonization chamber for treating the discrete articles with sulfur trioxide gas, and a neutralizing tank for treating the discrete articles with neutralizing fluid comprising the steps of: transferring the discrete articles one at a time in a continuous stream from the feeder box to the outer periphery of the sulfonization chamber,rotating the discrete articles a pre-determined number of revolutions per minute about a center axis of the sulfonization chamber,moving the rotating discrete articles radially inward from the outer periphery of the sulfonization chamber in a spiral path toward the center axis of the sulfonization chamber,treating the discrete articles with the sulfur trioxide gas as the discrete articles move in the spiral path, andtransporting the discrete articles at the center axis through a chamber bottom opening at the center axis to the neutralizing tank. 2. A method as set forth in claim 1 wherein said rotating the discrete articles is further defined by placing the discrete articles on a rotating dial plate having a circular periphery and presenting an upper surface and disposed in the sulfonization chamber. 3. A method as set forth in claim 1 wherein said moving the rotating discrete articles radially inward is further defined by using a plurality of arcuate guides extending perpendicularly from a guide arm toward the upper surface of the rotating dial plate and spaced radially outward from one another along an axis extending radially from the center axis of the sulfonization chamber. 4. A method as set forth in claim 1 including loading the discrete articles into the feeder box. 5. A method as set forth in claim 4 including feeding the ultra-dry air into the feeder box for drying the discrete articles. 6. A method as set forth in claim 1 including treating the discrete articles with the neutralizing fluid in the neutralizing tank. 7. A method as set forth in claim 6 including removing the discrete articles from the neutralizing tank. 8. A method for continuous sulfonization of discrete articles including a feeder box for drying the discrete articles with ultra-dry air, a sulfonization chamber for treating the discrete articles with sulfur trioxide gas, and a neutralizing tank for treating the discrete articles with neutralizing fluid comprising the steps of: loading the discrete articles into the feeder box,feeding the ultra-dry air into the feeder box for drying the discrete articles,transferring the discrete articles one at a time in a continuous stream from the feeder box to the outer periphery of the sulfonization chamber,rotating the discrete articles a pre-determined number of revolutions per minute about a center axis of the sulfonization chamber,moving the rotating discrete articles radially inward from the outer periphery of the sulfonization chamber in a spiral path toward the center axis of the sulfonization chamber,treating the discrete articles with the sulfur trioxide gas as the discrete articles move in the spiral path,transporting the discrete articles at the center axis through a chamber bottom opening at the center axis to the neutralizing tank,treating the discrete articles with the neutralizing fluid in the neutralizing tank, andremoving the discrete articles from the neutralizing tank. 9. A method as set forth in claim 8 wherein said rotating the discrete articles is further defined by placing the discrete articles on a rotating dial plate having a circular periphery and presenting an upper surface and disposed in the sulfonization chamber. 10. A method as set forth in claim 9 wherein said moving the rotating discrete articles radially inward is further defined by using a plurality of arcuate guides extending perpendicularly from a guide arm toward the upper surface of the rotating dial plate and spaced radially outward from one another along an axis extending radially from the center axis (A) of the sulfonization chamber.
