DEVICE FOR PRODUCING BITUMEN-POLYMERIC MATERIALS Russian patent published in 2005 - IPC

FIELD: chemical or physical processes.

SUBSTANCE: device comprises unit with a mixing member, branch pipe for supplying gas phase, and outer circulation circuit that is composed of lines for polymer solution and vapors. The line for polymer solution is additionally provided with the unit with mixing member made of a blade mixer mounted on the shaft. The unit is hollow and defines the passage for supplying gas phase. The outer circuit of circulation may be additionally provided with a condenser mounted in the vapor line and condensate collector connected with the unit with the mixing member. The units with mixing members may be also provided with deflecting baffles mounted on the inner sides of the units with a spaced relation to the blade b = (0.3-3)h_m, where h_m is the height of the mixer blade. The deflecting baffles are mounted at an angle to the axis of the unit with the mixing member.

EFFECT: enhanced efficiency.
