Description
Technical field
The present invention relates to a kind of spinning equipment, particularly relate to a kind of jet type electrostatic spinning equipment that can be used for producing in enormous quantities nanofiber.
Background technology
Mostly the device of present widely used electrostatic spinning nano fiber is single shower nozzle or many shower nozzles syringe-type device for spinning, as Chinese patent application ZL200420107832.5, ZL200420020596.3, ZL200320122276.4, ZL200410025622.6 etc., U.S. Pat 6616435, US6713011, US6753454, US6656394, world patent WO06043968, WO2005/073441, WO2005/073442, WO2006/018838, WO2006/007287, WO2005/026398, WO2005/123995, WO2004/016839, WO04074559, WO0209288A1, WO2005/099308, WO2006/049664, WO2005/090653A1, the multi-nozzle electrospinning apparatus structure schematic diagram that Fig. 1 arranges for matrix form.
No matter be single spray orifice or many spray orifices spinning process, because injection diameter is less, so have spinning efficiency and yield poorly down the easily stifled and cleaning difficulty of spinneret orifice, electric field serious interference between the adjacent spinning head can't satisfy the defectives such as requirement that production in enormous quantities and product are used.Even have indivedual patents such as WO 2005/090653A1 to adopt many spray orifices form of hydrojet that makes progress, but still have this shortcoming.
Summary of the invention
Technical problem to be solved by this invention provides a kind of jet type electrostatic spinning equipment that can be used for producing in enormous quantities nanofiber, to remedy the deficiencies in the prior art or defective, meets the demands of production and living.
In order to solve the problems of the technologies described above technical scheme that the present invention adopts be: a kind of jet type electrostatic spinning equipment that can be used for producing in enormous quantities nanofiber, comprise liquid storage tank 1, HV generator 2, shower nozzle 4, air pump 3 and reception pole plate 7, the upper end open of described liquid storage tank 1, the bottom surface of liquid storage tank 1 is provided with shower nozzle 4 vertically upward, shower nozzle 4 links to each other with air pump 3 by wireway 5, wireway 5 and air pump 3 connecting places are higher than the liquid level of liquid storage tank 1, liquid storage tank 1 links to each other with HV generator 2 by metal electrode, be provided with a conveyer directly over the liquid storage tank 1 and receive curtain 8, conveyer is formed by receiving pole plate 7 and deflector roll 9, receive curtain 8 and be close to reception pole plate 7 and deflector roll 9, provide tension force and part to transmit power by receiving pole plate 7 and deflector roll 9, receiving pole plate 7 links to each other with earth electrode 10 by deflector roll 9, receive curtain 8 one ends and connect unwinding roll shaft 11, the other end is connected with coiling roll shaft 12.
As optimized technical scheme: described shower nozzle 4 is a plurality of and presses matrix and arrange.
When the present invention works, at first inject solution or melt 6 in liquid storage tank 1, institute's liquid volume added should be lower than the upper port of liquid storage tank.Open air pump 3, air pressure is lower during beginning, earlier liquid in the wireway 5 is discharged, and slowly adds atmospheric pressure again, makes liquid level have rule vacuole, projection or fountain shape fluid column.Open HV generator 2 then, be adjusted to certain voltage.With polarized, electric charge will concentrate on protruding solution top to the liquid internal free charge under the high-pressure electrostatic effect, form taylor cone.One conveyer is arranged and receive curtain 8 apart from liquid storage tank 1 upper port certain distance, conveyer is formed by receiving pole plate 7 and deflector roll 9, receives pole plate 7 ground connection and forms negative pole, and form electric field between the liquid level.Under proper condition, because the effect of electrostatic force has the ejection of superfine liquid or melt jet from the taylor cone top, the directive negative plate is deposited on the reception curtain 8, forms a large amount of nanofibers, along with transmission device is with from the fibre-collecting zone.Receive curtain 8 and be wound on the unwinding roll shaft 11, the other end is connected on the coiling roll shaft 12, along with the carrying out of spinning, carries out unwinding and coiling with certain speed, thereby assurance fiber uniform fibers felt is with from spinning zone and is wound on the take up roll.
The invention has the beneficial effects as follows: can realize the needs of scale production of nanofiber, need not frequently to change spinneret orifice, and highly efficient in productivity, can satisfy the needs to nanofiber and Related product thereof such as production in enormous quantities and product application.
