Sharp tooth cage-shaped electrode electrostatic spinning device

Abstract

The invention discloses a sharp tooth cage-shaped electrode electrostatic spinning device. The sharp tooth cage-shaped electrode electrostatic spinning device includes a sharp tooth cage-shaped electrode, a power supply, and a collecting device; the sharp tooth cage-shaped electrode includes two end plates and one or a plurality of sharp tooth linear type electrodes, the two end plates are provided with a rotation shaft, and the sharp tooth linear type electrodes are provided with a plurality of sharp teeth which are at a side edge away from the rotation shaft, have the identical distance relative to an axis of the rotation shaft, and are evenly distributed; and the power supply is electrically connected to the sharp tooth cage-shaped electrode and the collecting device, and an electric field required by jet flows is formed between all the sharp teeth and the collecting device after the power supply is on. The sharp tooth linear type electrodes can combined into the sharp tooth cage-shaped electrode, the structure is simple, the processing is convenient, and all the electrodes can be easily arranged on the same circle, so that the uniformity of the electric field can be ensured; and when the plurality of sharp tooth linear type electrodes are arranged between the two end plates, and uniform distribution operation of a solution on other sharp tooth linear type electrodes can be completed through rotation of the rotation shaft during spinning of one sharp tooth linear type electrode, so that spinning work can be continuously performed, and the efficiency of the spinning can be improved.

Description

technical field [0001] The invention is used in the technical field of electrospinning, and in particular relates to an electrospinning device with tine cage electrodes. Background technique [0002] At present, nanofibers have been widely used in environmental protection, biomedicine and other fields, and the most widely used technology for producing nanofibers is electrospinning technology. This technology relies on the action of a high-voltage electrostatic field to stretch and split the jet, and finally Method of forming nanofibers. [0003] The industrial application of electrospinning nanofibers is inseparable from the mass production of electrospinning nanofibers. The current technology for mass production of nanofibers has multi-nozzle electrospinning devices. This method can realize mass electrospinning, but every The liquid supply of each nozzle varies greatly, and it is difficult to solve the problem of nozzle clogging and dripping; the first generation of spider...

[0003] The industrial application of electrospinning nanofibers is inseparable from the mass production of electrospinning nanofibers. The current technology for mass production of nanofibers has multi-nozzle electrospinning devices. This method can realize mass electrospinning, but every The liquid supply of each nozzle varies greatly, and it is difficult to solve the problem of nozzle clogging and dripping; the first generation of spider spinning technology can realize mass production, and the output is relatively large, but its energy consumption is large, and it is used for spinning The contact area between the solution and the air is relatively large, resulting in inconsistent spinning quality before and after, so it has been eliminated by Ermark Company. The second-generation spider spinning technology solves the problem of solution volatility, but sacrifices the output. At the same time, there is an electrode wire Difficult to clean
