Compared with the prior art, the multi-nozzle electrostatic spinning membrane manufacture device of the utility model has the characteristics of being reasonable in design, simple in structure, low in manufacture cost and capable of prepare large amount of even nanofiber membrane.
Description
Technical field
The utility model relates to a kind of electrostatic spinning apparatus, and a kind of multi-nozzle electrospinning film forming apparatus that Polymer Solution can be made nano fibrous membrane specifically is provided.
Background technology
The experimental provision of electrostatic spinning mostly is single shower nozzle greatly, and the per hour tens of approximately milliliters of the flow that its spinning solution passes through can not industrialization.Some researchers so that improve spinning efficiency, but because the electrostatic field between the shower nozzle disturbs, can not form uniform non-weaving cloth, so can only make coaxial fiber with many shower nozzles device for spinning.
Summary of the invention
The utility model is at above deficiency, provide a kind of reasonable in design, simple in structure, cost of manufacture is low, can prepare the multi-nozzle electrospinning film forming apparatus of nano fibrous membrane in a large number uniformly.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of multi-nozzle electrospinning film forming apparatus, comprise the electrospinning liquid supply system, described electrospinning liquid supply system connects the bar shaped reservoir by the spinning solution import on the bar shaped reservoir, and described bar shaped reservoir is provided with spinning head, and axially parallel bar shaped reservoir is provided with a rotatable cylinder that connects.
Connect 1～10 rev/min of a cylinder range of speeds, the drum diameter scope is 200～500mm.
The vertical distance range that connects between a cylinder and the bar shaped reservoir is 100～300mm.
The spinning head two rows are arranged alternately on the bar shaped reservoir, and the syringe needle internal orifice dimension is Ф 0.5～0.8mm, and length is 10～15mm, and the distance between the syringe needle is 10～15mm, and the syringe needle endoporus communicates with the bar shaped reservoir.
The flow of each syringe needle of control was at 10～20ml/ hour in the spinning process, and flow is controlled by the pressure reduction that the electrospinning liquid supply system provides.Adopt checker spinning head and the method that connects electrostatic field between a cylinder, eliminate that electrostatic field disturbs between shower nozzle, make nanofiber form uniform non-weaving cloth fiber type perforated membrane, generally about 200nm, the pm scope is arrived at nm in the aperture of film to fibre diameter.The shower nozzle number does not influence the system film uniformity, and shower nozzle is many, system membrane efficiency height.
Adopt to change to connect a cylinder rotating speed and electrostatic field transformation rate, the uniformity of controlling diaphragm, thickness deviation can be controlled in every square meter 1～10%.
Spinning head with connect electrostatic field between a cylinder and change by spinning head and realize displacement frequency 1～30 cycle per minute with parallel relative displacement between cylinder.
DC high-voltage power supply, voltage range are 0～30KV, maximum allowed current 2mA.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of structural representation of multi-nozzle electrospinning film forming apparatus.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Provide a most preferred embodiment below:
A kind of multi-nozzle electrospinning film forming apparatus, comprise electrospinning liquid supply system 1, described electrospinning liquid supply system 1 connects bar shaped reservoir 2 by the spinning solution import on the bar shaped reservoir 23, described bar shaped reservoir 2 is provided with spinning head 4, and axially parallel bar shaped reservoir 2 is provided with the rotatable cylinder 5 that connects.
Multi-nozzle electrospinning film forming apparatus of the present utility model prepares nano fibrous membrane with suitable Polymer Solution.Its process is that Polymer Solution (also claiming electrospinning liquid) flows out through spinning head 4 from electrospinning liquid supply system 1.Bar shaped reservoir 2 is connect dc high-voltage, connect a cylinder 5 ground connection, when spinning head 4 and connect between the cylinder 5 formed high electric field, electrospinning liquid formed Taylor's cone on spinning head 4 tops, because effect of electric field, liquid flow split becomes some threads, flows to connect a cylinder 5.The solvent evaporates macromolecular solid changes into fiber simultaneously, is connecing film forming on the cylinder 5, then it is taken off to get final product from connecing a cylinder 5.
This device can be used for multi-purpose system film, as lithium battery diaphragm, fuel cell barrier film, desalinization film, NF membrane etc.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
