Description
Technical field
Patent of the present invention belongs to the spinning equipment field, particularly relates to a kind of mechanical air bubble spinning device for preparing micron or nanofiber.
Background technology
Because have superhigh specific surface area, greatly draw ratio, high surface, superior mechanical performance characteristics such as (high-strength and high ductilities), nanofiber has obtained application more and more widely.It is one of the most effective current the most direct method that method of electrostatic spinning prepares nanofiber, and this device for spinning is adopted in industry at present and laboratory research more.The bottleneck problem that electrostatic spinning exists, the propelling speed of one of device composition micro-injection pump causes efficient extremely low, and the capillary syringe needle is made spinning head and is contained that equally efficient improves; Need to use high-pressure electrostatic voltage that the electromotive force of kilovolt is provided, there is certain potential safety hazard in operation.
Summary of the invention
The present invention for the technical scheme that technical problem adopted that solves the existence of preparation nanofiber is: but provide a kind of low energy consumption high-efficiency rate to prepare the mechanical air bubble spinning device of micron or nanofiber, and this device is made up of cylinder, dash receiver, liquid storage tank, air pump, wireway, shower nozzle, pendulum wire.Liquid storage tank upper end open, bottom surface are provided with shower nozzle and link to each other with air pump via wireway.The liquid storage tank top is provided with cylinder, and pendulum wire is fixed on cylinder surface, and dash receiver is positioned at the rear of liquid storage tank, and rib shape projection 8 is joined with the circumference that the pendulum wire rotation forms.
The liquid storage tank bottom surface is provided with shower nozzle, shower nozzle straight up, sprinkler height is higher than the bottom surface of liquid storage tank and is lower than free surface (0cm＜sprinkler height＜liquid level), and relevant parameters such as frequency that can produce according to the length and the required bubble of liquid level, pendulum wire and size carry out corresponding adjusting.
The quantity minimum of shower nozzle is 1, and maximum no maximum is selected according to the size and dimension of production efficiency, output and liquid storage tank.And shower nozzle can be various in the liquid storage tank bottom surface rules arrange (linear array, circumferential arrangement etc.), but also random alignment.
The cross section of shower nozzle can be circle, also can be square or arbitrary shape.The pore of shower nozzle can be opened at tube wall, also can open at Guan Ding, and the quantity of pore is decided according to production efficiency and output, when enhancing productivity, then increases stomatal number, its scope: minimum is 1, maximum no maximum.
According to the generation frequency and the quantity of the needed bubble of production efficiency, the flow rates of air-flow is controlled to be 0m/s～100m/s, and the pressure control range is 0Pa～10MPa.
Pendulum wire is fixed on cylinder surface, and its length is regulated according to the height and the liquid level of liquid storage tank, and an end of its vertical liquid level can fully be contacted with the spinning solution or the melt bubble that produce.
The diameter range of pendulum wire is 0.00 μ m～10cm, as required the fineness of producd fibers and deciding; The material of pendulum wire is a flexible material, is in contact with one another in stable conditionly with spinning solution or melt, is advisable so that chemical reaction not to take place; Pendulum wire also can be made into the pendulum face, and material is chosen for flexible material equally, and the product that spins out so then is film material.
The radical of pendulum wire is greater than one, do not have the upper limit, arranging density is decided according to the length and the spinning efficiency of cylinder, along the surface of cylinder or rule arrange (linear array for example, circumferential arrangement etc.) or at random random alignment, and according to the diameter of the cylinder plurality of rows that can be arranged in parallel.
There is a rib shape projection in the circumference joint that dash receiver and pendulum wire rotation form, and the angular range size between this projection and plate body is 0～90 °.
The rotation direction of cylinder is a clockwise direction in right view, is right-handed helix in the front view, inwardly rotation.
The generation approach of bubble can be by outside the shower nozzle ejection, also can be by in solution, adding blowing agent, or, form abundant bubble with the melt ebuillition of heated.
As optimized technical scheme: described shower nozzle is a plurality of to form a line, and pendulum wire can many be arranged in a row, and can place many rows on cylinder.
Beneficial effect
Can realize high efficiency, low energy consumption, the serialization production of micron or nanofiber, only use the pendulum wire of machinery rotation and the solution or the melt of bubbling just can prepare fiber, and production efficiency height, equipment are simple, low production cost, production process is short, simple to operate, adaptive is strong, satisfies the demand of current industrial commercialization to micron or nanofiber and Related product thereof fully.
When the present invention works, at first injection of polymer solution or melt in liquid storage tank 3, institute's liquid volume added should be higher than the height (shower nozzle 6 is fully submerged) of shower nozzle 6, is lower than the height of liquid storage tank, and the end of pendulum wire 7 is immersed fully.Open air pump 4, apply, continue for some time than low pressure, treat air-flow pressure and flow speed stability after, add atmospheric pressure gradually, the solution or the melt that enter shower nozzle 6 are discharged, form bubble clocklike on the free surface.Open the power switch of cylinder 1, cylinder 1 is rotated with stable rotating speed, when pendulum wire 7 goes on the free surface, contact with the bubble that produces, this moment, the end of pendulum wire 7 flooded spinning solution or melt, when it leaves liquid level, because the viscous force of polymer solution or melt, solution or melt are pulled out solution and are become thread.Because the centrifugal force that inertia force, viscous force, gravity and rotation produce, continuous, elongated fiber has just produced.When pendulum wire 7 went to dash receiver 2 places, the fiber that the end of pendulum wire 7 is adhering to cut mutually with rib shape projection 8, and fiber separates with pendulum wire 7, was deposited on the dash receiver 2, and final solvent evaporates forms a large amount of micron and nano-scale fiber.
