Description
Technical field
The utility model relates to carbon fiber equipment technical fields, specifically, being that a kind of carbon fiber continuous production is worn furnace and connect
The device of silk.
Background technique
Carbon fiber and its composite material are a kind of important feature materials of high technology content, have high specific strength, Gao Bimo
Amount, light, high temperature resistant, corrosion-resistant, endurance and the series of advantages such as thermal expansion coefficient is small are widely used in space flight and aviation, war
The slightly fields such as weapon, automobile, traffic, the energy, building and sports goods.China has begun to carbon early in six the seventies of last century
The research work of fiber, it is almost synchronous with the world.By effort in more than 40 years, have now been developed close to toray company
The carbon fiber product of T300, T700 level, but yield and quality stability is not able to satisfy domestic demand still, very with external gap
Far.The production of polyacrylonitrile-based carbon fibre mainly includes precursor production and precursor two processes of carbonization, and precursor production process is main
Including polymerization, deaeration, metering, spinneret, traction, wash, oil, dry it is fine and close, receive the processes such as silk；Carbonisation mainly includes putting
Silk, low-temperature carbonization, high temperature cabonization, surface treatment, starching drying, receives the processes such as silk winding, each in preparation process at pre-oxidation
Process can all influence the performance indicator and quality stability of product, during especially guaranteeing device operation in process of production
Temperature field, air-flowing environment, tension field etc., and the homogeneity of various fields then needs to reach by the production of continuous-stable.
According to statistics, during carbon fibre carbonizing, the especially production of kiloton stage arrangement, being raised to technological temperature from room temperature is needed
One day is taken, and temperature field, air-flowing environment, tension field reach stable uniform and then need -15 days 5 days in device, during this period, product
Indices fluctuation is larger, and qualified product yield is lower, and therefore, more and more carbon fiber manufacturer selections are former with online replacement
The mode of silk fluctuates to solve frequent heating and cooling bring, but because of the vigorous reaction of polyacrylonitrile fibril at high temperature, online
The method for changing silk is different, determine fiber can normal through pre-oxidation furnace and low temperature carbonization furnace, once fracture of wire occurs, then to whole
Set process units impacts, and even results in completely parking and other safety accidents.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, a kind of carbon fiber continuous production is provided wears furnace and connect silk
Device.
The purpose of this utility model is achieved through the following technical solutions:
A kind of carbon fiber continuous production wears the device that furnace connects silk, which is characterized in that in the one end on precursor head and short carbon filament
Caudal knot of fishing is connected to form the first connector, and the other end of short carbon filament and same station are connected in operation precursor tail portion caudal knot of fishing
Form the second connector；First connector and the second connector pass sequentially through 1# oxidation furnace, 2# oxidation furnace, 3# oxidation furnace, 4# with operation
Oxidation furnace, 5# oxidation furnace, 6# oxidation furnace；After the first connector and the second connector pass through 6# oxidation furnace, the first connector and the are cut
Short carbon filament between first connector and the second connector is changed to long carbon filament, forms third in a manner of fish tail knot and connect by two connectors
Head and the 4th connector.
The length of short carbon filament is 40cm.
The length of long carbon filament is 5m.
During carbon fibre carbonizing, the precursor as raw material will walk empty when being replaced, oxidation furnace holding technique
It is temperature-resistant, into before oxidation furnace, new precursor head and short carbon filament one end of about 40cm one section long caudal knot of fishing are connected shape
At the first connector, the short carbon filament other end and same station are connected to form the second connector in operation precursor tail portion caudal knot of fishing.
First connector and the second connector pass sequentially through 1#-6# oxidation furnace with operation, due to the first connector and the second connector
All it is that precursor is connected with carbonization, avoids and react heat accumulation caused by being connected directly because of precursor in oxidation process, so as to cause blowing
A possibility that with kindling.
After the first connector and the second connector pass through 6# oxidation furnace, the first connector and the second connector are cut, by the first connector
And the second short carbon filament between connector is changed to the long carbon filament for being about 5m, forms third connector and the 4th in a manner of fish tail knot and connects
Head.
Third connector and the 4th connector enter low temperature carbonization furnace with operation, due to high temperature (800 DEG C) in low temperature carbonization furnace
Effect, fiber weightlessness about 45-50% herein, filament contraction is more serious, due to having replaced long carbon filament, chemically reacts formation
Tension leads to fiber free shrink, avoids because overtension leads to the possibility of fiber fracture of wire, fiber passes through low-temperature carbonization
After furnace, subsequent handling can then be operated normally, and after product winder, be can be completed and once changed a process online.
Compared with prior art, the good effect of the utility model is:
First is that having saved the production time by way of changing silk online, production efficiency is improved, is avoided because furnace is worn in parking
Bring heating and cooling energy consumption and heating and cooling waste of time, meanwhile, it also avoids because heating and cooling are to temperature field and air-flowing environment
Caused by destroy, ensure that the consistency of product quality, second is that being connected between precursor and precursor using carbon filament, avoid because of tradition
Silk is changed online causes to react fracture of wire caused by heat accumulation and kindling hidden danger in oxidation furnace using connecing a rifle or directly knotting, third is that
According to the difference that different processes chemically react, short carbon filament and long carbon filament two ways are used, it is ensured that have suffered and change during silk
Passability.
