Summary of the invention
The technical problem that the present invention requires to solve provides a kind of two water circulation goosenecks of band vacuum that are used for the chemical fibre wet-spinning frame, the spinning solution that can make the gooseneck innermost layer keeps constant, temperature normal spinning, that guarantee spinning quality continuously in the spun filament process of setting.Make in conventional silk spinning high speed, the low type spinning technique that congeals into of extraordinary silk high temperature, all problems that produce owing to the gooseneck heat insulation effect is not good obtain fine solution.
Technical scheme of the present invention:
The two water circulation goosenecks of a kind of band vacuum of chemical fibre wet-spinning frame, it comprises mount pad 1, water inlet closure plug 2, internal layer insulating tube 3, water outlet closure plug 4, outer insulating tube 5, vacuum closure plug 6, vacuum heat-insulating pipe 7, jet holder 8, water supply connector 9, water out adapter 10, joint cover 11 and feed tube 12, feed tube 12 1 ends are connected with mount pad 1, and the other end is connected with jet holder 8 with joint cover 11, and internal layer insulating tube 3 is arranged on the feed tube 12, outer insulating tube 5 is arranged on the internal layer insulating tube 3, vacuum heat-insulating pipe 7 is arranged on the outer insulating tube 5, and an end of internal layer insulating tube 3 is connected with water inlet closure plug 2, and the other end is connected with joint cover 11, one end of outer insulating tube 5 is connected with water outlet closure plug 4, the other end is connected with joint cover 11, and an end of vacuum heat-insulating pipe 7 is connected with vacuum closure plug 6, and the other end is connected with joint cover 11, vacuum heat-insulating pipe 7 is communicated with inner chamber on the jet holder 8 by the through hole of joint cover 11, is provided with through hole between internal layer insulating tube 3 and the outer insulating tube 5.
The present invention compared with prior art has following beneficial effect:
This device is for adopting MULTILAYER COMPOSITE, double-deck hot water circuit, the new-type gooseneck of vacuum heat-preserving technology, be well positioned to meet the insulation requirement of chemical fibre wet spinning parts, can strictly control the spinning solution temperature, make it in high temperature stoste spinning low temperature coagulation forming class production process, to keep constant, thereby improve spinning speed and fiber quality greatly, enhance productivity.Simultaneously,, solved this difficult problem of stoste temperature constant, made the special fibre of researching and producing similar technology become possibility again, as high-performance polyacrylonitrile-based carbon fiber, aromatic series fiber, property vinal or the like owing to use this device.Through practice, obtain good result.
