Description
Technical field
The utility model relates to a kind of electrostatic spinning nozzle, especially relates to a kind of hemispherical electrostatic spinning nozzle.
Background technology
Can prepare the nanofiber of abundant species by electrostatic spinning technique, comprise organic, organic/inorganic is compound and inorganic nano-fiber, is one of the most important science of world's materials science field in recent ten years and technical activity.Electrostatic spinning and simple with its manufacturing installation, spinning is with low cost, can spin the advantages such as substance classes is various, technique is controlled, has become one of main path of effectively preparing nano-fiber material.Along with the development of nanometer technology, electrostatic spinning, as a kind of New Processing of the simple and effective nanofiber produced, will be played a great role in fields such as bio-medical material, filtration and protection, catalysis, the energy, photoelectricity, food engineering, cosmetics.
In electrostatic spinning field, preparation and the application of the aspect research electrostatic spinnings such as main device, material, processing conditions and structure from electrostatic spinning.
Traditional electrostatic spinning apparatus mainly by HV generator, micro-injection pump, be with syringe capillaceous and four parts of receiver to form.In recent years, electrostatic spinning apparatus is greatly developed, and current electrostatic spinning equipment is simple, easy to operate, but there is following shortcoming: the first, there is the capillary processing difficulties of superfine little micropore, cost is higher, and in spinning process, easily stop up, affect carrying out continuously of electrostatic spinning; The second, traditional electrostatic spinning apparatus efficiency is low, yields poorly, and is difficult to reach the object of high efficiency production.
Summary of the invention
The utility model object is to provide and can reduces costs, and improves the hemispherical electrostatic spinning nozzle of one of spinning production efficiency and output.
The utility model is provided with jet pipe and nozzle, and jet pipe bottom is inserted on nozzle top, and nozzle bottom is hemisphere, and hemisphere is provided with mesh.
The order number of described mesh can be 10～500 orders.
Described jet pipe bottom can be 3～4mm with the length that nozzle top coordinates.
Described jet pipe bottom can be provided with the chamfering with the assembling of nozzle top.
Because the Lower Half of nozzle is hemisphere, hemisphere is provided with mesh, therefore the jet in shower nozzle can be divided into the flow of solution that multiply diameter is less and passes through mesh under the driving of certain flow rate, under the effect of high-voltage electrostatic field, flow of solution can form taylor cone at mesh place, drawn forms independently jet of multiply.The utility model can produce multiple jets in hemispheric nozzle face simultaneously, increase the jet quantity producing by a shower nozzle, production efficiency and the output of spinning are greatly improved, and the spinning fibre diameter of preparing with this shower nozzle is little, can guarantee the uniformity of fibre diameter, prepare the spinning fibre of better quality.Because jet pipe bottom can be provided with the chamfering of being convenient to the assembling of nozzle top, therefore make the assembling of nozzle and jet pipe simple and convenient, can realize the replacing of different size nozzle, and the part coordinating guarantees the seal of whole shower nozzle.
Accompanying drawing explanation
Fig. 1 is the structure composition schematic diagram of the utility model embodiment.
Fig. 2 is the E-E cutaway view of Fig. 1.
Fig. 3 is the upward view of Fig. 1.
The specific embodiment
Referring to Fig. 1～3, the utility model embodiment is provided with jet pipe 1 and nozzle, and the bottom of jet pipe 1 is inserted on the top 21 of nozzle, and the bottom 22 of nozzle is hemisphere, and hemisphere is provided with mesh 3.
The utility model is coordinated and is formed a kind of high efficiency electrostatic spinning nozzle that can form multi-direction electrostatic spinning jet by jet pipe and nozzle.Wherein, jet pipe material is polypropylene (PP), and the material of nozzle is brass.
The shape of nozzle can be formed by punch process, and the copper mesh hole of nozzle can be formed by Laser Processing, and mesh face can normative reference copper mesh order number and specification.
The length of the jet pipe bottom coordinating with nozzle top is 3～4mm, jet pipe bottom can be provided with the chamfering 4 of being convenient to the assembling of nozzle top, make the assembling of nozzle and jet pipe simple and convenient, can realize the replacing of different size nozzle, and the part coordinating guarantees the seal of whole shower nozzle.
First, by punching press and laser technology, latten(-tin) is made to the hemispherical jet rose of 100 order numbers, nozzle bottom is laser boring place.In addition, then make jet pipe by punching and turner technology.
By the hemispherical jet rose of 100 order numbers and corresponding jet pipe assembling.The chamfering of jet pipe bottom is for the assembling on jet pipe bottom and nozzle top, and jet pipe bottom and nozzle top are interference fit, directly assemble and can make it fix, and guarantee its seal.
Before using, the nozzle segment of shower nozzle is carried out to hydrophobicity processing, stop solution to accumulate at copper hole surface.Solution is flowed down with constant speed, and the solution flow rate of setting should make copper hole surface just accumulate without solution.When experiment, on solution inside or nozzle, apply high-voltage electrostatic field, make solution form in time jet at mesh, guarantee that hemispherical copper hole surface accumulates without solution.
Under the effect of certain solution flow rate and high-voltage electrostatic field, the utility model can form multiple jets, can collect electrospun fibers placing a receiver apart from shower nozzle a distance.The shower nozzle of this many Jet models that carry out continuously can improve efficiency, the output of electrostatic spinning, and can, by changing the aperture in copper hole or the diameter of order number change spinning of nozzle, improve spinning fibre quality.This shower nozzle equipment is simple, easy to operate, can meet the batch production demand of scale in reality.
