The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
As shown in Figure 1, the utility model provides a kind of 6 black of polyamide fibre slice continuous production device, a kind of 6 black of polyamide fibre
It is sliced continuous production device, including：Mixing tank 1, preceding poly- reactor 2, rear poly- reactor 3, pelleter 4, extraction tower 5, drying
Tower 6, finished product storage tank 7, evaporator 8, cracking reaction kettle 9, feed tank 10, blend tank 11, the mixing tank 1 are poly- anti-before being sequentially connected
Answer device 2, rear poly- reactor 3, pelleter 4, extraction tower 5, drying tower 6, finished product storage tank 7, the extraction tower 5 also with evaporator 8 into
Mouth end is connected, and the cracking reaction kettle 9 is separately connected 8 outlet end of evaporator and mixing tank 1, and the feed tank 10 is separately connected
Blend tank 11 and preceding poly- reactor 2.
The preceding poly- reactor 2 is voltage-resistant reactor.
The evaporator 8 is triple effect evaporator.
The feed tank 10 is equipped with flow controller.
The utility model realization method is as follows：Prepared add is added in liquid caprolactam after being mixed in proportion with concentrate
Add agent, the Hybrid Heating in mixing tank 1；Meanwhile the mixture of carbon black and ethylene glycol, carbon black being added in blend tank 11：Ethylene glycol=
0.01-0.2 introduces feed tank 10 after being sufficiently stirred.
Poly- reactor 2 before mixing tank 1 and the liquid of feed tank 10 are sent into simultaneously, it is preceding to gather for pressurized operation, the polymerization of generation
Object in the past poly- 2 bottom of reactor after poly- gear discharging is pumped to before menstruation poly- reactor 3, caprolactam it is first in rear poly- reactor 3
Open loop, addition reaction are first carried out, then completes polycondensation reaction, so that polymer chain rises to the required degree of polymerization.
Polymer melt is through note band, cooling, solidification, in 4 inscribe of pelleter at regular cylindrical chips.Contain oligomerization
The slice of object is extracted in extraction tower 5 by the thermal process water of counter current contacting therewith.Extraction water containing oligomer is discharged by tower top, is sent
To evaporator 8, the hot nitrogen that the slice by extraction is successively added in drying tower 6 is constantly dry, one addition of hot nitrogen
6 epimere of drying tower, this strand of hot nitrogen mainly remove the surface water of slice, one hot nitrogen is sent into the hypomere of drying tower 6, the hot nitrogen
Gas is then used for removing the residual moisture in slice, and heats slice, keeps its molecular weight constant.
Slice after drying is aqueous≤0.05%, it is cooling after under nitrogen protection with pulse conveying device by slice send at
Product storage tank 7 is used as international sale after metering packing.
In device in addition containing water caprolactam evaporation after ultimate density reach 50-90%, the caprolactam containing water into
Enter cracking reaction kettle 9, the obtained concentrate after cracking reaction is directly by poly- reactor 2 before being pumped to, in this way, caprolactam can
100% utilization, without the loss of caprolactam and oligomer.The clean water being evaporated is condensed and is sent in water basin, and
Send extraction back to therefrom, such water realizes closed cycle.
The utility model has the beneficial effect that：1）Continuous production, production efficiency is high, and low energy consumption；2）It is black that polyamide fibre 6 can be produced
Color is sliced；3）Extra raw material can reuse, non-environmental-pollution.
