Embodiment 1

[0039] like figure 1 As shown, when the present invention is in use, the liquid storage device 3 is first filled with spinning solution, and the solution is injected into the bubble generator 5 through the connecting pipe 9, and the flow rate is controlled by the valve and the flow rate control device 12, and the nanoparticles are regulated. The nano particle content of ejection in the container 8, the airflow generator 6 transmits the airflow of suitable size in the airflow chamber 2 and the three-way pipe 7 through the airflow intensity control device 10, so that bubbles are generated in the holes of the bubble generator 5, and then the bubbles are Under the action of the air flow, when the air bubble explosion assisting device 4 whose temperature has been adjusted by the temperature or speed control device 11 is encountered, it explodes instantaneously, and the speed at which the broken bubble fragments are stretched in the thinning air flow cavity becomes larger, and finall...

Embodiment 2

[0042] like figure 1 As shown, the installation steps of the air bubble air spinning device in use are consistent with those in Example 1. When the bubbles in the bubble generating device 5 are exploded, the bubble explosion assisting device is as follows: image 3 What is shown can be an electric heating component, regulated by the temperature or speed control device 11 ; it can also be a rotating fine needle component, regulated by the temperature or speed control device 11 .

[0043] In summary, compared with the prior art, the beneficial effects of the present invention include:

[0044] 1. When the bubble meets the bubble blasting booster device, it explodes instantly and is stretched in the high-speed airflow field, which makes the prepared nanofibers thinner in diameter and higher in yield, and there is no electrostatic process. The whole device is safe and easy to control; at the same time, through the nanofiber Nanoparticles are added to the airflow cavity in the pa...

Abstract

The invention provides an air-flow / bubble spinning device. The spinning device comprises an air flow chamber and an air flow generator. A liquid storing device is arranged on one side of the air flow chamber, and is directly connected with a bubble generator via a communication pipe. The air flow chamber is communicated with the communication pipe via a three-way pipe. A nano-particle container is arranged on the communication pipe between the air flow chamber and the liquid storing device. An electric heating assembly is arranged on the bubble generator. A receiving device is arranged right above the air flow chamber. According to the invention, bubbles suddenly blast when meeting the electric heating assembly and stretched in the high-speed airflow field, so prepared nano-fibers are very thin and yield is higher; without any static electric process, so the whole device is highly safe and easy to control; by adding nano-particles in the air flow chamber via the nano-particle container, nano-thin films can be mixed with the nano-particles more uniformly in the spinning process, so various kinds of fibers can be effectively prepared; and by controlling shape and nature of the particles, appearance of the fibers can be precisely controlled.

Description

technical field [0001] The invention belongs to the spinning field, in particular to an air bubble spinning device. Background technique [0002] Nanofibers have the characteristics of ultra-high specific surface area, extremely large aspect ratio, high surface activity, superior mechanical properties (high strength and high toughness), etc., and are used in textile engineering, environmental engineering, biotechnology, medical and health care, energy storage, military It has very broad application prospects in different fields such as anti-terrorism security. The batch production of nanofibers is a hot and difficult direction in recent years. The most direct and basic method for traditionally preparing ultrafine fibers and nanofibers is electrospinning. At present, the preparation of nanofibers in laboratories and industries widely adopts single-nozzle or multi-nozzle syringe electrospinning nanofiber devices. [0003] There are some drawbacks in traditional nano-electros...
