A multi-nozzle air bubble spinning device

Abstract

The invention provides a multi-nozzle airflow and air bubble spinning device. The multi-nozzle airflow and air bubble spinning device comprises a spraying-out unit and a receiving unit, wherein the spraying-out unit comprises a liquid storage groove, a high-pressure airflow generator, air bubble nozzles, a liquid supplying device and a bubbler; an air bubble spraying pipe plate covers the top of the liquid storage groove; a plurality of air bubble spraying pipes with the air bubble nozzles are uniformly arranged on the air bubble spraying pipe plate; the high-pressure airflow generator is connected with the liquid storage groove through one air spraying pipe with the middle axis overlapped with the middle axis of the air bubble spraying pipe plate; the receiving device comprises a receiving device and a negative-pressure box; the receiving device is composed of a receiving plate and roller shafts and the roller shafts are located on the two sides of the receiving plate. According to the multi-nozzle airflow and air bubble spinning device, the liquid storage groove which is provided with the plurality of air bubble nozzles and is sealed is adopted, and the negative-pressure box generates negative pressure, so that solution nature change and environment pollution, caused by solvent volatilization, can be effectively avoided; meanwhile, the problems that fibers in an airflow and air bubble spinning process are not easy to collect and the fibers are not uniformly collected are effectively solved, and furthermore, the yield of a micro-nano fiber material prepared by airflow and air bubble spinning is improved.

Description

Technical field [0001] The invention relates to the field of spinning mechanical equipment, in particular to a multi-jet air bubble spinning device. Background technique [0002] Micro-nano fiber materials have a series of advantages such as small size, large specific surface area, and good fiber continuity, so they have broad application prospects in environmental health, information technology, energy security, biomedicine, national defense and military fields. At present, electrospinning technology is recognized as the most effective way to quickly obtain micro-nano fibers with different diameters, different morphologies, and different functions. [0003] However, for the traditional single-needle or multi-needle electrospinning technology, it is difficult to meet the mass production of micro-nano fibers due to the defects of easy clogging of the needles, difficult to clean, and low yield. In order to overcome such defects as much as possible, the researchers have proposed some...
