Abstract
The utility model discloses a novel highly-effective electrostatic spinning, belongs to the field of electrostatic spinning, and comprises a spray orifice and a cone, the engagement portion of the cone and the spray orifice are divided into a plurality of planes, a balance groove is processed on the spinning cone, the spinning solution or the fusant flows from the gap between each planes and the spray orifice to the spinning cone, at this time the fusant has a certain inhomogeneities, when the fusant arrives to the balance groove, it will perform secondary shunting, thereby leading the fusant to be distributed more evenly, when the big end circumference of the spinning cone is evenly distributed with solution or fusant, added with the electrostatic field, the big end circumference of the spinning cone will form a plurality of injection streams, The utility model is on the basis of original high-efficiency spray head, the evenness of the plurality of injection streams are greatly improved by the design of the balance groove, thereby obtaining more even electrostatic spinning fiber.
Description
Technical field
The utility model relates to a kind of electrostatic spinning nozzle, belongs to the electrostatic spinning field.
Background technology
Along with the intensification of nanometer technology, electrospinning process can be prepared nano level fiber and becomes one of current research focus owing to it.Electrospinning process has been acknowledged as the simplest effective method of preparation nanofiber, and existing at present 30 multiple polymers successfully make superfine fibre by the method, and minimum diameter reaches tens nanometers.About the result of study of electrostatic spinning, pertinent literature all is index over the years increases.
Electrostatic spinning comprises solution electrostatic spinning and melt electrostatic spinning again.The ratio of solvent surpasses 90% in the spinning solution of solution electrostatic spinning, and the spinning process solvent evaporates, thereby its efficient is extremely low, is generally 0.01g/min; Though and melt electrostatic spinning does not have the evaporation of solvent, efficient is high more a lot of than solution electrostatic spinning, and the utility model does not use traditional capillary, and use a kind of novel high efficiency spinning nozzle, melt spinning efficient is greatly improved, but because the stream interface of high efficiency shower nozzle is a circular cone, only once shunt, can not guarantee the uniformity of spinning well through tangent plane.
The utility model content
The electrostatic spinning nozzle of a kind of improved novel efficient that the utility model proposes, it does not need to use capillary, thereby avoided the capillary blocking problem and processed difficulty capillaceous, also have the injection stream that can form multiply by this shower nozzle, improved the efficient of electrostatic spinning greatly, and, increased compensating groove, melt is carried out second diffluence, increased the uniformity coefficient of cone lower end melt, the uniformity between multiply spray silk is improved.
The utility model provides a kind of electrostatic spinning nozzle of novel efficient, comprise spray orifice (1) and cone (2) two parts, cone (2) comprises the cooperation cone (4) that cooperates with spray orifice (1) endoporus again and is used to spray the spray wire cone (7) of silk, the cooperation cone (4) of cone (2) cuts out several planes (5) and chamfering (6) with the mating part five equilibrium of spray orifice (1) endoporus, cut-out is not for cooperating the cooperation conical surface (8) on the cone (4), cooperate the conical surface (8) to cooperate with spray orifice (1) endoporus, spray wire cone (7) is provided with the compensating groove (10) that is used for solution or melt second diffluence.Spinning solution or melt flow to the conical surface of spray wire cone (7) from the gap of each plane (5) and spray orifice (1) endoporus, uneven melt can locate to carry out second diffluence, mixed distribution again in compensating groove (10), then, continue to flow along spray wire cone (7), when the spray screw tap big end circumference of face (9) is evenly distributed with solution or melt, after adding electrostatic field, on the spray screw tap big end circumference of face (9), will form the uniform injection stream of multiply (3).
The electrostatic spinning nozzle of the novel efficient that the utility model proposes, for the effect that can better play shunting, mix, the compensating groove (10) of its spray wire cone (7) can be two or more version.And the shape of cross section of the compensating groove (10) on its spray wire cone (7) can be circular-arc or polygon.
The electrostatic spinning nozzle of this novel efficient that the utility model proposes has tangible difference with general electrostatic spinning nozzle, and it does not need to use capillary.Spinning solution or melt are to flow out from the fit clearance of spray orifice (1) and cone (2), flow out after overbalance groove (10) carries out second diffluence.Melt will pass through compensating groove (10) after flowing out from the gap, with original because various factors and the melt of skewness carries out second diffluence, makes melt can flow to the big end that sprays wire cone (7) conical surface equably at last.

Fig. 1 is the assembling schematic diagram of the electrostatic spinning nozzle of a kind of novel efficient of the utility model.
Fig. 2 is the cone axis mapping of the electrostatic spinning nozzle of a kind of novel efficient of the utility model.
Among the figure: the 1-spray orifice; The 2-cone; The 3-injection stream; 4-cooperates cone; The 5-plane; The 6-chamfering; 7-sprays wire cone; 8-cooperates the conical surface; The big end circumference of 9-spray screw tap face; The 10-compensating groove.
The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
Embodiment 1
Among Fig. 1 and Fig. 2, the internal diameter of spray orifice (1) is 2mm, cooperation cone (4) five equilibrium of cone (2) cuts out 4 planes (5), spray orifice (1) is 0.1mm with the maximal clearance that cooperates the conical surface (8), the gradient of the conical surface of spray wire cone (7) is 58 °, spray wire cone (7) small end rounding obtains 45 ° chamfering (6), and the degree of depth of compensating groove (10) is 1.5mm, and the spray screw tap big end circumference of face (9) diameter is 6mm.Spray orifice (1) closely cooperates with cooperating the conical surface (8), and shower nozzle is installed on the melt spinning device, and spinning material is the PP particle.When the spray screw tap big end circumference of face (9) is evenly distributed with the PP melt that melts via the melt spinning device, melt is through the second diffluence of compensating groove (10), flow downward again, add electrostatic field, the injection stream of multiply (3) evenly sprays along the big end circumference of spray screw tap face, the uniformity coefficient of its spinning becomes 10 μ m～40 μ m by 10 original μ m～100 μ m, and its uniformity obviously improves.
