Abstract

The invention relates to a jagged annular needleless static spinning device and an application method thereof. The device comprises a liquid supply system and a nanofiber collection system. The liquid supply system is in the structure of a communicating vessel composed of a liquid storage bottle and a jagged annular needleless sprayer. The jagged annular needleless sprayer is in the gap structure composed of an outer annular liquid groove and an inner annular liquid groove. The center of the bottom of the outer annular liquid groove is provided with a metal pipe. The center of the bottom of the liquid storage bottle is connected with one end of a liquid guide pipe, the other end of which is connected with the metal pipe. The liquid guide pipe is provided with a switch. By turning off the switch on the liquid guide pipe, a proper amount of polymer solutions is added into the liquid storage bottle. By turning on the switch, polymer solutions flow into the annular gap formed by the jagged outer annular liquid groove and the inner annular liquid groove. By adjusting the height of the liquid storage bottle, polymer solutions can overflow the annular gap. By turning on a motor, a metal cylinder is guaranteed to normally rotate at the certain speed. By turing on a high-voltage power supply, voltage is slowly increased. The jagged annular needleless static spinning device and the application method thereof help to achieve automatic supply of solutions to the sprayer and operation is performed conveniently.

Description
