Lotus seedpod electrospinning spray head

Abstract

The invention relates to the technical field of electrospinning. A lotus seedpod electrospinning spray head comprises a casing, the bottom surface of the casing is an arc face, a solution inlet is formed in the top surface of the casing, a solution channel is formed in the casing, the bottom surface of the solution channel is an arc face, a plurality of conductor nozzles are evenly arranged on the bottom surface of the solution channel, the conductor nozzles extend out of the casing to form injection channels, a high-voltage electrode is further arranged on the bottom surface of the solution channel, the high-voltage electrode is electrically connected with the conductor nozzles, an air guide pipe is arranged in the casing and at the position under the solution channel, the air guide pipe is communicated with an external auxiliary air flow generator, upper through holes and lower through holes are formed in the upper surface and the lower surface of the air guide pipe, the conductor nozzles penetrate through the upper through holes and the lower through holes, the bore diameter of the lower through holes of the air guide pipe is larger than the outer diameter of the conductor nozzles, flow guide barrels are arranged at the edges of the lower through holes and at the peripheries of the conductor nozzles, and openings matched with the bottoms of the flow guide barrels are formed in the bottom surface of the casing. The method obviously improves electrospinning jet flow density and nano-fiber injection efficiency.

Description

technical field [0001] The invention relates to the technical field of electrospinning, in particular to a showerhead electrospinning nozzle. Background technique [0002] Nanofibers have good application prospects in air filtration, water pollutant removal and biomedicine, and have begun to be commercialized. As an emerging nanofiber jet manufacturing technology, electrospinning has shown many advantages in many nanofiber manufacturing technologies due to its simple equipment, convenient operation, low cost, and wide source of raw materials, and has become the mainstream preparation of nanofibers. Technology has been widely promoted. [0003] How to improve the production efficiency of nanofibers and enhance the uniformity of fibers is the focus and difficulty in the field of electrospinning manufacturing technology. At present, a single spinning nozzle used in traditional electrospinning can only produce one jet, and the output is only about 0.02g / h. The production effic...

Problems solved by technology

The jet is generated from the free surface of the solution, the initial diameter of the jet varies greatly, and the uniformity of the jet varies greatly; moreover, the unconstrained spinning jet is prone to fluctuations, and the jet diameter varies greatly, which seriously affects the uniformity of the electrospun nanofiber membrane. sex and quality
