The specific embodiment
Further narrate the present invention below in conjunction with embodiment and accompanying drawing thereof.Specific embodiment does not constitute the restriction to claim of the present invention just in order further to clearly demonstrate the concentricity controller structure of spinning head of the present invention.
The insertion tubular type spinning head of the present invention's design is (hereinafter to be referred as spinning head, referring to Fig. 1-4), comprise and insert pipe 1, spinning nozzle shell 2 and spinnerets 3, it is characterized in that this spinning head is fitted with concentricity adjuster 4, described concentricity adjuster 4 is made of the sleeve pipe 41, jackscrew 42 and the adjustment screw 43 that cooperate with described spinning nozzle shell 2; The uniform respectively 3-4 of having a retaining thread hole 412 and 3-4 adjusting screwed hole 413 on two cross sections that are parallel to each other of described sleeve pipe 41; Described jackscrew 42 and adjustment screw 43 are equipped with described retaining thread hole 412 and adjusting screwed hole 413 respectively; Described sleeve pipe 41 is installed on the described spinning nozzle shell 2 by described jackscrew 42, and described adjustment screw 43 withstands on the outer rim of described spinnerets 3.
Spinning head of the present invention is to insert on the tubular type spinning head basis existing, has been equipped with described concentricity adjuster 4 (referring to Fig. 1-2), and it is simple in structure, only comprises a cylinder-shaped sleeve 41, a 3-4 jackscrew 42 and 3-4 adjustment screw 43.Utilize described sleeve pipe 41 to be sleeved on easily on traditional spinning nozzle shell 2, be very beneficial on existing spinning head, installing, save cost, help practical application and promote.Have 3 screwed holes in that embodiment on two cross sections that are parallel to each other of described sleeve pipe 41 is uniform respectively: have the retaining thread hole 412 of space 120 ° (uniform) on cross section, described jackscrew 42 is equipped with described retaining thread hole 412; Also have the adjusting screwed hole 413 of space 120 ° (uniform) on another cross section, described adjustment screw 43 is equipped with described adjusting screwed hole.Consider the well-balanced property and the stability of structure, interlaced 60 ° of angles, locus of the described retaining thread of embodiment hole 412 and described adjusting screwed hole 413.Utilize the jackscrew (also can adopt screw) 42 supporting, described sleeve pipe 41 (concentricity adjuster 4) stably is packed on the spinning nozzle shell 2, constitute spinning head of the present invention with retaining thread hole 412; And utilize the adjustment screw 43 supporting to withstand on the outer rim of described spinnerets 3 (promptly described adjustment screw 43 being installed on the same cross section of sleeve pipe 41 with described spinnerets 3) with regulating screwed hole 413, constitute spinneret orifice and manage the online adjustable mechanism that exports concentricity with inserting.
Though the retaining thread hole 412 of concentricity adjuster 4 embodiment of the present invention and equipped jackscrew 42 with regulate screwed hole 413 and equipped adjustment screw 43 and respectively be 3, the design numbers of not getting rid of a certain cover in them or two covers are greater or less than 3 of embodiment.
The not constraint of material that sleeve pipe 41 of the present invention uses can be adopted the same material with traditional spinning head, also can adopt different material.Present embodiment adopts copper product.
In order to obtain the hollow-fibre membrane of uniform wall thickness, spinning head unique design of the present invention the concentricity adjuster, utilize sleeve pipe 41 to be sleeved on easily on traditional spinning nozzle shell 2.The operation principle of spinning head of the present invention is: when producing hollow-fibre membrane, if because a variety of causes causes casting solution deviation to occur by annular spinneret orifice outlet distribution or off-centre is (unstable as casting solution output, extrude thread and present bending, core liquid phenomenon such as grow out frequently when serious) time, in time utilize the precession or the back-out of 1-3 the adjustment screw 43 of embodiment as required, 43 of mobile adjustment screw of trace are the spinnerets 3 of pushing tow radially, carry out online adjusting in time, eliminate described deviation or off-centre, make spinneret orifice and insert that the pipe outlet is actual to keep concentric, thereby obtain the uniform hollow-fibre membrane product of wall thickness (referring to Fig. 5 (a) and (b)).
Online adjusting for convenience, described adjustment screw 43 disposes knurled knob 431.For the accuracy of online adjusting, described adjustment screw 43 disposes the major diameter knurled knob 431 of 15-30mm.The diameter of the knurled knob 431 of embodiment is 20mm.
Test shows that spinning head of the present invention is applicable to the development and the production application of the hollow-fibre membrane of phase inversion, stretching pore method and thermic phase method.
The present invention does not address part and is applicable to prior art.
