Helical Ribbon Mixer
US Patent:
5741066, Apr 21, 1998
Filed:
Apr 17, 1997
Appl. No.:
8/840862
Inventors:
Dale Presnell - Fort Worth TX
Assignee:
Hayes & Stolz Industrial Manufacturing Company Inc. - Fort Worth TX
International Classification:
B01F 708
US Classification:
366320
Abstract:
The mixer has a chamber with a shaft supported for rotation along an axis along the length of the chamber. Two sets of outer ribbon members are coupled to the shaft such that the two set of outer ribbon members are located about 180 degrees apart and extend helically around the shaft. Two sets of inner ribbon members are coupled to the shaft such that the two sets of inner ribbon members are located about 180 degrees apart and extend helically around the shaft. A drive is coupled to the shaft for rotating the shaft and hence the ribbon members about the axis. The two sets of outer ribbon members are located radially outwardly of the two sets of inner ribbon members. Each set of outer ribbon members has at least two radially spaced apart outer ribbon members. Each set of inner ribbon members has at least two radially spaced apart inner ribbon members. One of the two sets of ribbon members has a left hand pitch and the other of the two sets of outer ribbon members has a right hand pitch.
Counterpoise Helical Ribbon Mixer
US Patent:
5299865, Apr 5, 1994
Filed:
May 3, 1993
Appl. No.:
8/056481
Inventors:
Dale Presnell - Fort Worth TX
Assignee:
Hayes & Stolz Industrial Manufacturing Company Inc. - Fort Worth TX
International Classification:
B01F 708
US Classification:
366300
Abstract:
The mixer includes a chamber having first and second, side-by-side tub like cavities with first and second rotatable shafts located in the first and second cavities respectively. Each shaft has two ribbon members coupled to the shaft and which extend helically around the shaft along a substantial length of the shaft with the two ribbon members located about 180 degrees apart. The ribbon members of the two shafts do not intermesh but are located close to each other. A drive mechanism is provided for rotating the two shafts in opposite directions to cause the ribbon members of the two shafts to move toward each other below the plane of the two shafts, upward, and away from each other above the plane of the two shafts for mixing the particulate material. The ribbon members of the two shafts cause the particulate material in the two cavities to move in opposite directions along their lengths. Pitched paddles coupled to one end of one shaft and to one end of the other shaft at opposite ends of the chamber, cause pressure equalization and the particulate material at one end of the chamber to move from the first cavity to the second cavity and at the other end of the chamber to move from the second cavity to the first cavity to provide lateral circulation of the particulate material in the mixer chamber.
