NOVELTY - Device for extracting pyrethrin from Pyrethrum comprises a material storage case, a sealing auger, a desolventizing machine, a condenser, an evaporator, a pump and a condensation kettle. The material storage case is connected with a multi-level counter current extractor (5) by a first sealing auger (4). The multi-level counter current extractor is respectively connected with a first pump (14), a second curve scraper blade (6) and a second condenser (31). The second curve scraper blade is connected with a desolventizing machine by a second sealing auger which is serially connected.    USE - The device is useful for extracting pyrethrin from Pyrethrum.    ADVANTAGE - The device is economical, safe, and provides socioeconomic benefits without environmental pollution, and has high production efficiency; suitable for continuously producing pyrethrin in large scale industries to meet the requirements.    DETAILED DESCRIPTION - Device for extracting pyrethrin from Pyrethrum comprises a material storage case, a sealing auger, a desolventizing machine, a condenser, an evaporator, a pump and a condensation kettle. The material storage case is connected with a multi-level counter current extractor (5) by a first sealing auger (4). The multi-level counter current extractor is respectively connected with a first pump (14), a second curve scraper blade (6) and a second condenser (31). The second curve scraper blade is connected with a desolventizing machine by a second sealing auger which is serially connected. The desolventizing machine is connected with a second scraper blade for discharging materials. The first pump is connected with a flashing case I by a cyclone hydraulic separator, a filter, an oil kettle and a first-effect long tube evaporator which are orderly and serially connected. The flashing case I is connected with a condensation kettle by a second-effect long tube evaporator, a flashing case II, a third-effect film-reduction evaporator, a flashing case III and a second pump which are orderly and serially connected. The condensation kettle is connected with a finished product plant through a third pump. The flashing case I, II and III and the condensation kettle are connected with a fourth condenser. The fourth condenser is connected with a diversion box.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic representation of the device for extracting pyrethrin from Pyrethrum.
