ENERGY-SAVING EXTRACTION DEVICE FOR TREATING SCRAPS OF NEODYMIUM IRON BORON

摘要

Disclosed is an energy-saving extraction device for treating scraps of neodymium iron boron. The device comprises universal wheels (1), a light liquid pump (4), a countercurrent extraction tower (8) and an electric motor (13). A mounting and fixing frame (2) is fixed above the universal wheels. An electrical cabinet (3) is arranged on a side of the mounting and fixing frame, and the light liquid pump is mounted inside the mounting and fixing frame. A control valve (5) is arranged above the light liquid pump, and a filter (6) is mounted above the control valve. A light liquid exit tube (7) is fixed above the filter, and the countercurrent extraction tower (8) is mounted under the light liquid exit tube. A glass observation cylinder (9) is fixed on a side of the countercurrent extraction tower, and a sensor (10) is arranged on a side of the glass viewing cylinder. A heavy liquid pump (16) is fixed above the mounting and fixing frame. Use of the device in an extraction process has the advantages of saving labor costs, improving work safety, increasing heat exchange efficiency, enhancing extraction effect, increasing productivity and recovery rate, and affording good extractive distillation performance.
