Abstract

The invention discloses a device for preparing natural nanometer fibers through a continuous ultrasonic method and the continuous ultrasonic method and aims to solve the problems that the energy distribution is uneven, the test scale is small and batch industrial production of natural nanometer fibers cannot be met in a prior ultrasonic method for separating and preparing natural nanometer fibers. The device comprises that an ultrasonic tank is embedded in a work platform; a discharge pipe is connected with a discharge port; a plurality of ultrasonic transducers are evenly distributed along the length direction of the ultrasonic tank, and probe ends of the ultrasonic transducers are arranged in the ultrasonic tank; a controller and an ultrasonic generator are arranged under the ultrasonic tank successively; and a reaction still is arranged outside the work platform and above the ultrasonic tank, an input end of a feed pipe is connected with a discharge port of the reaction still, and an output end of the feed pipe is communicated with the ultrasonic tank. The method comprises preparation of a reactant mixture of natural fibrous materials; delivery of the reactant mixture to the ultrasonic tank; ultrasound treatment; discharging; and continuous preparation.
