Electrostatic spinning device

Abstract

The invention discloses an electrostatic spinning device comprising a charging basket, a piston, a spinning nozzle, a high-voltage power supply device, a receiving plate and a grounding power line, wherein the high-voltage power supply device is connected to the spinning nozzle, the receiving plate is arranged corresponding to the spinning nozzle, and the grounding power line is used for grounding the receiving plate; the electrostatic spinning device also comprises double layers of glass covers arranged at the periphery of the spinning nozzle to form an closed spinning region, an interlayer space located between the double layers of glass covers and a temperature detecting device used for detecting the temperature in the closed spinning region, wherein the interlayer space is connected with a cold and hot source device which is used for selectively conveying a clod source or hot source towards the interlayer space according to the temperature indication of the temperature detecting device. According to the invention, the spinning region is designed into a closed space formed by the double layers of glass covers, different cold sources or hot sources can be introduced into the interlayer space so as to perform circulated heating or cooling reaction, and meanwhile, the arranged temperature detecting device can be used for simply and rapidly feeding back the spinning temperature so that the cold and hot source device can be used for alternately introducing the cold sources and the hot sources into the interlayer space.

Description

technical field [0001] The invention relates to an electrostatic spinning device, in particular to an electrostatic spinning device capable of adjusting the spinning temperature. Background technique [0002] Electrospinning is a special form of electrostatic atomization of polymer fluids. At this time, the substances split by atomization are not tiny droplets, but tiny jets of polymers, which can run for a long distance and finally solidify into fibers. Compared with electrospinning, electrostatic atomization uses different working media. Electrostatic atomization uses low-viscosity Newtonian fluid, while electrospinning uses high-viscosity non-Newtonian fluid. Correspondingly, the in-depth study of electrostatic atomization technology also provides a certain theoretical basis and knowledge base for the electrospinning system. [0003] In recent years, the preparation of nanofiber materials by electrospinning technology has become one of the most important academic and tec...
