The technology of preparing of the nano materials such as assembling, electrostatic spinning have many advantages, such as that easy to operate, preparation flow is short, material selection is extensive.
And compared with conventional textile fabric material, nano-fiber material is possessed many and is difficult to open up under large scale due to minimum scale
Existing characteristic, such as apparent surface and interfacial effect, distinctive small-size effect, great specific surface area and high hole
Rate etc..Therefore nano-fiber material possesses wider application field, such as in air filtration, water-oil separating, medical accessory, group
The directions such as weaver's engineering support, nano-fiber material all play the effect for enabling entire industry attract attention for it, it is made to possess non-ordinary light
Bright application prospect.
Traditional electrostatic spinning apparatus is based on single needle or Multi needle, but two kinds of devices all have lacking for low output
It falls into, it is difficult to meet the output needed for industry.In recent years, design improvement electrostatic spinning apparatus improves the yield of its nanofiber
Have become a big research hotspot in electrostatic spinning technique field.In worldwide, mass production Static Spinning Nanowire
The device and method of dimension also continue to bring out to blowout.Wherein most well-known is exactly that Elmarco companies rely on Czechly Liberec
The Nanospider electrostatic spinning apparatus of college of engineering's exploitation, realizes commercially producing for electrostatic spinning nano fiber earliest.
The equipment for realizing mass production Electrospun nano-fibers at present, spinning direction are oneself of anti-gravity formula mostly
It is lower and on, and in traditional fibrous material field, the collecting direction of fiber on the contrary, the therefore techno-absence in this direction,
The application of electrostatic spinning in actual production is limited to.And the major reason for limiting its direction is feed liquid way, for mass
For production equipment, the direction that a large amount of spinning solution needs are supplied to, and change its device is then easy to so that solution leakage, nothing
Method continuous production simultaneously influences spinning process.Therefore, design one kind mass production electrostatic spinning nano fiber but also can change it
Spinning direction, and ensure that spinning process continuous-stable electrostatic spinning apparatus is particularly necessary.
Invention content
The technical problem to be solved by the present invention is to：The technology of mass production Electrospun nano-fibers at present is spun
Silk direction be more it is single from bottom to top, limited to electrostatic spinning technique and widely applied.
Technical solution is used by the present invention solves the above problems：There is provided a kind of suitable gravity multi-slice brush electrostatic spinning
Device, which is characterized in that including mutually matched reciprocating motion type brush head and multi-slice spinneret, under the multi-slice spinneret
Side is equipped at least two triangular prism pieces, and multi-slice spinneret is connect with high pressure positive electrode；The reciprocating brush head includes and feed flow
The brush head of device connection, brush head are connect with motor, and motor is fixed on holder；Brush head is matched equipped with multiple with triangular prism piece
V-groove.
Preferably, the liquid feed device is micro-injection pump, and brush head is connect by hose with micro-injection pump.
Preferably, the section of the triangular prism piece below the multi-slice spinneret is isosceles triangle, the isosceles triangle
Vertex it is down-set, bottom edge length be 10-20mm, a height of 100-150mm, a length of 300-400mm of rib of triangular prism piece, bottom
Edge polishing is sharp.
It is highly preferred that being 150-300mm the distance between at the top of two triangular prisms.
Preferably, the material of the brush head is polytetrafluoroethylene (PTFE)；The material of triangular prism piece is brass.
The present invention also provides a kind of brush electrospinning process of suitable gravity multi-slice, which is characterized in that using above-mentioned suitable
The brush electrostatic spinning apparatus of gravity multi-slice is opened micro-injection pump and motor so that brush head moves back and forth, and is more
Lamella spinneret paints spinning solution；High pressure positive electrode is opened, high pressure is slowly increased, when voltage is more than critical value, is started quiet
Electrospun is collected by collection device, forms nanofiber.
The present invention devises a kind of device and method that can carry out electrostatic spinning along gravity direction from top to bottom, compared to
Current mass electrostatic spinning technique, realizes the breakthrough on spinning direction；The electrostatic spinning technique uses multi-slice spinning
Head carries out the preparation of needle-free mass electrostatic spinning nano fiber, had both avoided the blocking of nozzle, also substantially increases spinning effect
Rate and yield；It uses reciprocating motion type brush head to dip solution for spinneret, greatly improves solution utilization ratio, it is same with this
When, overcome the difficulty of solution drips so that spinning process can with steady and continuous carry out；In addition spinneret itself constructs letter
It is single, convenient for cleaning and operation.So the mass electrostatic spinning process along gravity direction may be implemented using the present invention, breach
Mass prepares the limitation on electrostatic spinning nano fiber production mode reform, has widened the application prospect of electrostatic spinning technique.
