Description
Technical field
The utility model relates to a kind of electrostatic spinning apparatus, 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 occurs that from it the history in 100 years is arranged so far nearly, yet this technology does not also realize industrialization till now.
The principle of electrostatic spinning forms electric field between the two by applying high voltage between shower nozzle and receiving system, making exactly, and polarized melt or solution are ejected on the dash receiver under the electric field force effect, form ultra-fine fiber.But present existing electrostatic spinning apparatus, what adopt mostly all is the single wire vent of capillary, spinning efficiency is low.The appearance of efficient spinning nozzle, spinning efficiency is greatly improved, but still can not satisfy industrialized demand, and the rounded distribution of its spun plurality of fibers is unfavorable for collecting and further processing and manufacturing of spinning fibre, in addition, a lot of full-bodied melts are after arriving shower nozzle, and cooling makes spinning be difficult to carry out rapidly.
Summary of the invention
The purpose of this utility model is to propose a kind of yi word pattern shower nozzle, form the injection stream of multiply by this shower nozzle, and make spinning fibre be two platoon leaders' yi word pattern, not only can improve the efficient of electrostatic spinning greatly, optimize the arrangement architecture form of spinning fibre, the be more convenient for reception of fiber overcomes the rounded distribution of low, spun plurality of fibers of present spinning efficiency and is unfavorable for collecting and the further drawback of processing and manufacturing of spinning fibre.
The utility model provides a kind of novel straight-strut electrostatic spinning spray nozzle, it comprises connector, drainage core and three parts of a cabinet frame, wherein, connector and drainage core are by being threaded, the drainage core is connected by screw with a cabinet frame, adjustable angle between two 1 cabinet frames, a heating rod and a cabinet frame adopt and are connected.The drainage core is provided with and is used to guide the drainage trough of melt flows and is used for the material annular compensating groove of sub-distribution again, one cabinet frame is provided with a cabinet frame groove surface of guiding melt flows, the heating rod and the temperature sensor of control melt temperature are installed, and, be provided with projection that is used for the melt shunting and the tip that forms spinning at a cabinet frame downside.Spinning solution or melt flow to a cabinet frame respectively by two drainage troughs between connector and drainage core, can carry out sub-distribution again during the annular compensating groove of material on the drainage core of flowing through, and then outflow connector, groove on a cabinet frame slowly flows, when being evenly distributed with solution or melt on the cabinet frame, after adding electrostatic field, on a cabinet frame two inclines, will form the injection stream of multiply.
A kind of novel straight-strut electrostatic spinning spray nozzle that the utility model proposes, spinning solution or melt are to flow out the drainage trough between connector and drainage core, fit clearance between connector and drainage core can not be too big, otherwise spinning solution or melt can flow to such an extent that can not form injection stream too soon, suitable gap should be that spinning solution or melt are just rested on the cabinet frame projection, and do not drip, with reference to the optional 1～2mm of drainage trough radius.
A kind of novel straight-strut electrostatic spinning spray nozzle that the utility model proposes, angle between two cabinet frame is adjustable, with reference to angle is 140～170 °, the diameter of its concrete angle and drainage trough is relevant with the viscosity of material, the number of one cabinet frame is two, two one cabinet frame symmetric arrangement, or be a plurality of, a plurality of cabinet frames are circumferentially evenly arranged, with further raising spinning efficiency.
The drainage core is provided with the annular compensating groove that is used to guarantee both sides one cabinet frame flow, can distribute the material of both sides one cabinet frame to guarantee that the both sides mass flow is suitable once more, the annular compensating groove is arranged at drainage core 1/3rd and highly locates, and is semi-circular structure, and annular balance groove radius is 1～2mm.
The cross section of drainage trough can also can be squarely for circle, and the side of a cabinet frame can be smooth surface or has the version of uniform drainage trough, and the drainage core is a solid.
One cabinet frame is provided with and has most advanced and sophisticated projection, is used for the shunting of spinning melt or solution, and the radical of spinning fibre is determined, most advanced and sophisticated design helps the gathering of electric charge, is convenient to the formation of spinning.
The utility model is owing to changed traditional electrostatic spinning structure capillaceous, with electrostatic spinning by single wire vent mode, become many and be the parallel rectangular yi word pattern form of two row, improved the efficient of electrostatic spinning greatly, simultaneously, improved the version of spinning, for certain basis has been established in the industrialization of electrostatic spinning.
