Embodiment
Embodiment one：Illustrated with reference to Fig. 1, the PAN base carbon fiber protofilaments spinning spray in present embodiment
Filament plate includes the body 1 of tabular, some spinneret orifices 2 is set on body 1, the one side of spinneret orifice 2 is charging aperture, and another side is
Material mouth, body 1 is circle；The spinneret orifice 2 is to be arranged by 12 identical graphic elements 3 by annular display, each figure list
Spinneret orifice 2 in member 3 is arranged in fan-shaped, has 500 spinneret orifices 2 in each unit.The spinneret orifice 2 is circular port；Spinneret orifice
2 aperture is 50 microns.The thickness of body 1 is 2.5mm, and body 1 can be using tantalum processing.The spinneret orifice 2 is in graphic element 3
Inside displayed from inside to outside in concentric structure, preceding 6~8 interlamellar spacing is equal and wide than below.
Present embodiment spinneret is used for the carbon fiber for producing 12K.
Embodiment two：Illustrated with reference to Fig. 1 and 2, the spinneret assembly in present embodiment, as can be known from Fig. 2,
The distribution assembly is made up of distribution plate 7, swash plate 9, support meanss 10, service 6, distribution container 4, cross flow passage 8.Its
In, support meanss 10 are horizontally disposed with, and distribution container 4 is arranged on the horizontal plane of support meanss 10, and distribution plate 7, which is fixed on distribution, to be held
At the import of device 4, so that solution realizes distribution when entering distribution container 4.There is one to be arranged on support at the import of distribution plate 7
Swash plate 9 on the horizontal plane of device 10.The angle of swash plate 9 and horizontal plane is 45 degree, and the angle with distribution plate 7 is also 45 degree.So
Angle solution flow rate can be made moderate, be easy to distribution.No person, distribution plate 7 and horizontal plane angle cross conference and cause turbulent flow, it is too small then
Easily cause flow velocity of the solution on distribution plate 7 uneven.The horizontal segment of service 6 is connected with the upper end of swash plate 9, the level
Section forms the advection section of liquid flowing.The cooperation of advection section and swash plate 9 can make solution more uniform before distribution plate 7 is entered,
Be conducive to preventing tow from filigree occur and silk or skin-core structure.6 points of service is ascent stage 61 and advection section 62, is being risen
Section 61 is provided with the check-valves 63 and flow valve 64 that can be connected with computer or control system, wherein, flow valve 64 is arranged on
The dirty section of check-valves 63.Meanwhile, the cross flow passage 8 being connected with swash plate 9 is connected with the two ends of distribution plate 7 and service 6,
To prevent spinning solution from flowing to the both sides outflow from swash plate 9 when on swash plate 9.Container 4 is distributed, the liquid outlet of distribution plate 7, which is set, to be installed
The spinning head 5 of spinneret described in embodiment one, the spinneret direction of spinning head 5 is consistent with direction of liquid flow, and spinning head 5 leads to
Cross PAN conveyance conduits 12 to connect with metering device 11, metering device 11 and computer interlocked control PAN flow.Metering device
11 connect with PAN storage devices.
When in use, stoste is flowed into advection section 62 from the ascent stage 61 of service 6, turns again to cross flow by swash plate 9,
Entered after being distributed finally by distribution plate 7 in distribution container 4.Stoste is to first pass through vertical stream, then switchs to advection, turns again to pass through
Distribution plate 7, can so reduce the bulbs of pressure of stoste, reduce the generation of simultaneously silk and sick silk.
