Problems solved by technology

[0003] In the preparation process of liquid polymer, it needs to be dispersed by dispersing equipment; dispersing equipment is a kind of mixer in a broad sense, because the high-speed agitator can form a strong turbulent flow locally, usually has a strong impact on the material Dispersing and emulsifying effect, so this type of high-speed mixer is also called a dispersing machine. The existing dispersing equipment is easily damaged, the dispersing effect is not good, it cannot meet the needs of users, and its service life is short.

Abstract

The invention proposes a dispersing device for preparing nanofibers, which includes a dispersing housing, a dispersing chamber is arranged in the dispersing housing, and a dispersing assembly is arranged in the dispersing chamber; the number of dispersing assemblies is at least two, and the dispersing assembly includes a dispersing assembly Shaft, the dispersing shaft is vertically and rotatably arranged in the dispersing chamber, the upper part of the dispersing shaft is provided with an upper dispersing structure, and the lower part of the dispersing shaft is provided with a lower dispersing structure; the top of the dispersing shaft of one of the dispersing components passes through the dispersing chamber and is fixed A first sector gear, the first sector gear meshes with the second sector gear fixed on the servo motor, and the servo motor drives the second sector gear to rotate, so that the dispersing assembly rotates simultaneously in the dispersing chamber; the present invention improves the The stability ensures the dispersion effect.

Description

technical field [0001] The invention relates to a dispersing device, in particular to a dispersing device for preparing nanofibers. Background technique [0002] Electrospinning technology is currently one of the most important basic methods for preparing continuous nanofibers. Electrospinning first appeared in 1934. Formalas first introduced an electrospinning device using electrostatic force to produce polymer fibers in its patent, which opened up the field of electrospinning technology since then. Electrospinning technology is mainly through the high voltage loading between the spinning nozzle and the receiving device, the surface of the polymer droplet suspended on the spinning nozzle will be induced to charge, the electrostatic repulsion between the surface charges and the external electric field The droplet will become conical due to the applied Coulomb force. When the voltage gradually increases to exceed the critical value, the electrostatic force overcomes the sha...
