Abstract

A porous bubble electrostatic spinning device comprises a liquid storage tank, a high pressure electrostatic generator, an air pump, a sprayer, and a dash receiver, wherein the sprayer is connected with the air pump through an air duct, the dash receiver is connected with a grounded electrode, an opening is arranged at the upper end of the liquid storage tank, the liquid storage tank is connected with the high pressure electrostatic generator through a metal electrode, the liquid storage tank is internally provided with a middle flat plate, and a plurality of small holes with adjustable diameters are formed in the middle flat plate in a penetrating way. As the small holes are formed in the middle flat plate, solution in the liquid storage tank generates a large quantity of bubbles through the plurality of small holes under the action of the air pump. When filed stress is greater than surface tension of the solution, and jet flow is ejected from the top of the bubbles and is deposited on the dash receiver to form a large amount of nanofiber. The porous bubble electrostatic spinning device can produce the nanofiber in a large scale, so that according to the device, the production efficiency is high, the production cost is low, the equipment is simple, the operation is easy, the adaptability is high and the requirement of batch production can be met.

Description

technical field [0001] The invention relates to the field of spinning equipment, in particular to a porous bubble electrostatic spinning device capable of efficiently preparing nanofibers. Background technique [0002] Electrospinning technology is currently one of the most direct and basic methods for preparing ultrafine fibers and nanofibers. Nanofibers prepared by electrospinning technology have ultra-high specific surface area, large aspect ratio, high surface activity, and superior The mechanical properties (high strength and high toughness) and other characteristics have very broad application prospects in different fields such as textile engineering, environmental engineering, biotechnology, medical and health care, energy storage, military and anti-terrorism security. [0003] At present, the preparation of nanofibers in laboratories and industries widely adopts single-nozzle or multi-nozzle syringe electrospinning nanofiber devices. Such as Chinese patent applicati...
