Abstract
The utility model discloses a kind of PAN base carbon fiber protofilaments spinning filter, it is related to a kind of filter.It is bad that the utility model solves existing filter filter effect, and the shortcomings that easily causing spinneret hole plug is not suitable for carbon fiber spinning.The utility model includes screen modules, and screen modules are laemodipodiform, is made up of 4 layers of screen pack altogether, and from the inside to the outside, from large to small, innermost layer plays a supportive role in the aperture of screen pack.The utility model is designed reasonably, it is simple in construction, spinneret hole plug is effectively reduced, good filtration effect, improves production efficiency, reduces production cost.
Description
Technical field
It the utility model is related to a kind of filter.
Background technology
Carbon fiber be using polyacrylonitrile (PAN) fiber, viscose rayon or pitch fibers as precursor, by heating except carbon elimination with
A kind of high intensity, high modulus fibre made of outer other element of contact.It has good chemical stability and high temperature resistant, resistance to
The performances such as burn into rub resistance, endurance, it is to prepare the superior structural material in high-performance composite reinforcing material, thus it is extensive
Applied to fields such as weaving, chemical industry, machinery, aviation, building, sports goods.
Carbon fiber is for raw material with acrylonitrile (AN) with PAN fiber, and dimethyl sulfoxide (DMSO) (DMSO) is solvent, in initiator
The lower polymerization of effect is made, and obtains fiber by spinning.
The quality of carbon fiber will be influenceed containing impurity in spinneret production, therefore need to filter before spinneret.
Existing filter is mostly leaf filter, and filter effect is bad, the shortcomings that easily causing spinneret hole plug.
Utility model content
It is bad that the utility model will solve existing filter filter effect, the shortcomings that easily causing spinneret hole plug, no
Suitable for carbon fiber spinning；Provide a kind of PAN base carbon fiber protofilaments spinning filter.
A kind of PAN base carbon fiber protofilaments spinning filter of the utility model, including screen modules, screen modules
For laemodipodiform, it is made up of 4 layers of screen pack altogether, from the inside to the outside, from large to small, innermost layer plays a supportive role in the aperture of screen pack.
From outside to inside, screen modules are that have the first screen pack 1, the second screen pack 2, the 3rd screen pack 3 and filter screen branch
Support 4 is formed, and the aperture of screen support frame 4 is 3~4mm, and the aperture of the first screen pack 1 is micron order, the hole of the second screen pack 2
Footpath is 0.2~0.5mm, and the aperture of the 3rd screen pack 3 is 1~2mm.
Further limit：Screen support frame 4 is cylindricality filter screen and is process by stainless steel.
The material of second screen pack 2 is polypropylene needled filter felt.
First screen pack 1 is processed by non-woven fabrics.
The aperture of first screen pack 1 is 1~5 micron.
The central shaft of filter of the present utility model is be arranged in parallel with jet tray, and spinning solution is noted inside filter
Enter, after filtering into spinning head cavity, then by spinneret spinneret.
The utility model is designed reasonably, it is simple in construction, spinneret hole plug is effectively reduced, good filtration effect, improves production effect
Rate, reduce production cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Illustrated with reference to Fig. 1, a kind of PAN base carbon fiber protofilaments spinning filter, including screen modules, filtering
Screen component is laemodipodiform, is made up of 4 layers of screen pack altogether, and from outside to inside, screen modules are that have the first screen pack 1, the second mistake
Filter screen 2, the 3rd screen pack 3 and screen support frame 4 are formed, and the aperture of screen support frame 4 is 3mm, the aperture of the first screen pack 1
For 2 microns, the aperture of the second screen pack 2 is 0.2mm, and the aperture of the 3rd screen pack 3 is 1mm；Screen support frame 4 is cylindricality filter screen
And it is process by stainless steel；The material of second screen pack 2 is polypropylene needled filter felt.The material of first screen pack 1 is nonwoven
Cloth.
