Problems solved by technology

[0005] The use of batch electrospinning devices to prepare nanofibers is conducive to the industrialization of nanofiber preparation. The current batch electrospinning devices do not use the solution to generate jets to control the solution, which seriously affects the quality of the prepared fibers due to the poor uniformity of solution coating. , so that the prepared fibers vary in thickness. At present, most electrospinning devices p

Abstract

The invention relates to the technical field of electrostatic spinning, in particular to an evenly-liquid-spraying batch electrostatic spinning device. The evenly-liquid-spraying batch electrostatic spinning device comprises a base plate, a liquid even-distribution device, at least one liquid supply device, at least one needle point array device, a collecting plate and a high-voltage power source. The two sides of the base plate are provided with guide rails respectively. Capillary tubes for liquid to flow out are distributed on the bottom face of the liquid even-distribution device. The liquid supply device is used for supplying the required liquid to the liquid even-distribution device. The needle point array device is arranged on the base plate, a nozzle is formed in the needle point array device, and the outlet direction of the nozzle faces the bottom face of the liquid even-distribution device. The collection plate is arranged above the liquid even-distribution device and the needle point array device. The anode of the high-voltage power source is electrically connected with the collecting plate. The cathode of the high-voltage power source is electrically connected with the needle point array device and earthed. The device can achieve evenly-liquid-spraying batch electrostatic spinning.

Description

technical field [0001] The invention relates to the technical field of electrostatic spinning, in particular to a batch electrostatic spinning device for uniform coating liquid. Background technique [0002] Membrane technology is an efficient water treatment technology with low operating cost and high efficiency. The smaller the diameter of the fibers that make up the membrane, the more effective it is to remove impurities in the solution. It is difficult to spin fibers with a diameter of less than 500nm by traditional spinning methods , while the diameter of the fiber spun by electrospinning can be as small as 1nm, and has the characteristics of porosity and large specific surface area, which has advantages that traditional membranes cannot match. [0003] The diameter of nanofibers prepared by it is smaller than that of cells, which can simulate the structure and biological function of natural extracellular matrix. Surface energy materials can be used to obtain super-hyd...
