Description
Technical field
The present invention relates to electrostatic spinning technique fields, more particularly to a kind of wheel sprayer cleaning device.
Background technique
Electrostatic spinning is the technology when the most general spinning nanofiber of former, and product has very excellent property
Can, if any great specific surface area, it can neatly carry out surface-functionalized arrangement and excellent mechanical behavior etc., Ke Yiying
Use organizational project, wound dressing, drug release, filtering material, composite reinforcing material, sensor etc..Due to electrostatic spinning work
Skill is simple, and preparation flow is shorter than traditional conventional spinning, and product function is excellent, and it is special to obtain the U.S. from Anton formhals1934
Since benefit, electrostatic spinning is always the objective of the struggle of fibre science man and weaving developer for a long time.Such nanofiber
The leading products of China's new century will be become.Market potential is huge, and prospect is very wide.
Traditional single needle electrostatic spinning apparatus is made of high voltage power supply, liquid-supplying system and collection system three parts.
Liquid-supplying system includes syringe pump, medical needle tubing and hollow metal needle, the material for needing spinning is initially dissolved in appropriate molten
In agent, and it is added in the needle tubing of connection hollow metal needle.Apply high pressure in metal needle, and reception device is grounded, from
And high voltage electric field is formed between metal needle and reception device.High voltage electric field is to the electric field force of drop and the work of surface tension of liquid
With contrary, an outside power is generated in droplet surface, the drop of jet port is made to gradually become taper by hemispherical
(Taylor cone).When electric field progressively increasing to the surface tension, the viscous force that are enough to overcome solution the effects of, jet stream is just from drop
Surface sprays, and experience whip is dynamic to be then formed by curing nanofiber, deposits to collection device.
However the nanofiber yield that single needle electrostatic spinning apparatus obtains is very low, it is difficult to meet nanofiber industrialization and answer
Demand, and it is easy to happen blocking, it is unfavorable for continuous spinning.Electrospun nano-fibers mass system is realized about earliest
Standby commercialized device is the Nanospider electrostatic spinning dress that Elmarco company relies on the exploitation of the Czechly Liberec college of engineering
It sets, the subsequent following prior art discloses:
104862788 A of patent CN discloses a kind of jet auxiliary Multi needle electrostatic spinning apparatus and its preparation Nanowire
The method for tieing up net, which can be improved the yield of nanofiber, but be easy blocking since the use of syringe needle still has syringe needle
And between Multi needle the shortcomings that interfering with each other, the distribution of nanofiber is easy irregular, and the arrangement mode influence factor of syringe needle is multiple
It is miscellaneous.
Patent CN205856663U discloses a kind of porous type taper electrostatic spinning nozzle device, opens on Conic nozzle surface
There are multiple holes, the problem of arrangement of multiple syringe needles reduces syringe needle blocking, but solution feed flow controls between complex and jet stream
It is closer, the jet stream of outer ring will be repelled by inner ring, and fiber is unevenly distributed and not enough concentrates.
102660783 A of patent CN discloses a kind of porous bubble electrostatic spinning device, which passes through in liquid bath bottom
It is passed through air and forms bubble generation jet stream in high polymer free surface, the yield of nanofiber is improved by this method, still
The formation and rupture of bubble be it is random and unstable, therefore the spinning jet of the device easily occur during the spinning process it is unstable
The problem of, while high polymer free surface and air contact range are larger, solvent is volatile.
Patent ZL201310032194.9 discloses a kind of umbrella-shaped electrostatic spinning sprayer and electrostatic spinning method, this method
The mass preparation of nanofiber may be implemented, but disadvantage is that the solution Free Surface of umbrella shower nozzle connects with atmospheric environment
Touching, solvent highly volatile, to influence whether the quality of nanofiber.
Therefore, how the maximum difficulty of spray head that mass prepares nanofiber at present is solving the problems, such as spray head blocking
The contact surface for reducing solution and air simultaneously, keeps the concentration of solution identical, guarantee prepares the stabilization of the quality of nanofiber.And
Realize that the means of this purpose other than changing traditional needle-based or free surface formula feed liquid method, also need cleaning to be in time set in
The solution at spray head edge.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of wheel sprayer cleaning devices, are avoided that due to solution
Sticky, the problem of solvent is volatile, and caused solution freezes solidly on spray head, easily causes blocking, so that the sustainable progress of spinning, forms
Nano fibrous membrane quality it is more stable.
The technical solution adopted by the present invention to solve the technical problems is: a kind of wheel sprayer cleaning device is provided,
Including rotating wheel, motor and waste collection slot, the rotating wheel is mounted on the inner upper of waste collection slot, the motor
Shaft be connected with rotating wheel and motor side is fixed with waste collection slot inner wall.
As a supplement to the technical solution of the present invention, the rotating wheel and waste collection slot are all made of poly-
Tetrafluoroethene material.
As a supplement to the technical solution of the present invention, the waste collection slot is in rectangular box structure,
The side and upper end of the waste collection slot are opened wide.
As a supplement to the technical solution of the present invention, the open side edge in waste collection slot side
The range of the shortest distance between edge and rotating wheel is 10mm-20mm.
The utility model has the advantages that the present invention relates to a kind of wheel sprayer cleaning device, when spinning solution is more sticky or molten
Agent volatilization it is too fast when, be easy spray head moving distance both ends solidification it is blocking, four sets of wheel sprayer cleaning devices are placed in
The edge on the both sides of the supplying cap of liquid feed device, rotating wheel is located at spray head slightly below, opens motor, driving rotating wheel is to far from spray
The position rotation at head center, the waste for solidifying blocking is hit down and is collected into waste collection slot.Wheel spray head of the invention is clear
It is clean to be avoided that due to the problem of solution is sticky, solvent is volatile, and caused solution freezes solidly on spray head, easily causes blocking, so that spinning
The sustainable progress of silk, the quality of the nano fibrous membrane of formation are more stable.
