Description
Technical field
The utility model belongs to the carbon fiber precursors drying device of carbon fibre producing facility, more particularly to constant temperature.
Background technology
Drying plant is indispensable part in carbon fiber precursors production process, by the fiber of compacting by drying
The performance indications that drawing extends up to precursor could be carried out again in steam drafting.But fiber, in drying course, single beam is fine
Drying degree difference is big between different spinning position fibers in dimension, and meeting fiber stretching orientation in subsequent steam drafting is uneven, sternly
Lousiness can be produced in the case of weight.
The content of the invention
For the influence precursor quality problems occurred in the drying course of fiber, the utility model can effectively control drying
Temperature in casing matches with drying roll temperature, so as to reach good drying effect, reduces the discreteness of fibre property, subtracts
Few lousiness, the long-range stability of fibre property is improved, aoxidize the stable operation of carbonisation for the later stage and stable performance is established
Basis.
The technical solution of the utility model is as follows：
Carbon fiber precursors drying device, it includes drying box, it is characterised in that：Hot-rolling is provided with described drying box
Unit, carbon fiber precursors turn round from hot-rolling unit upstream, heating coil are provided with described drying box, heating coil is with steaming
Vapour source is connected, and steam control valve is provided between vapour source and heating coil, thermal resistance, thermal resistance are provided with the drying box
It is connected with steam control valve.
The outlet of described heating coil is provided with drain valve.
Described hot-rolling unit includes the support base being arranged in drying box, and the side of support base is provided with multiple hot-rollings.
The utility model has the advantages that：
The utility model sets heating coil in drying box, and the environment temperature in drying box is adjusted, made
Carbon fiber precursors are dried under conditions of relatively constant temperature, overcome environment temperature and heat in the prior art in drying box
There is the problem of fiber quality stability difference that the temperature difference is brought in roll temperature, so as to reach good drying effect, reduce fibroid
Can discreteness, reduce lousiness, improve the long-range stability of fibre property, for the later stage aoxidize carbonisation stable operation and
Stable performance lays the foundation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
1 is drying box in figure, and 2 be hot-rolling unit, and 3 be carbon fiber precursors, and 4 be heating coil, and 5 be steam control valve, 6
It is thermal resistance for vapour source, 7,8 be drain valve.
Embodiment
The utility model is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, carbon fiber precursors drying device, it includes drying box 1, hot-rolling is provided with described drying box
Unit 2, carbon fiber precursors 3 are turned round from the upstream of hot-rolling unit 2, and heating coil 4, heating dish are provided with described drying box 1
Pipe 4 is connected with vapour source 6, and steam control valve 5 is provided between vapour source 6 and heating coil 4, is provided with the drying box 1
Thermal resistance 7, thermal resistance 7 are connected with steam control valve 5, and thermal resistance detects to the temperature in drying box, when temperature is with setting
When constant temperature degree has error, adjust the aperture of steam electromagnetic valve, control into the steam of heating coil flow, so as to realize
Temperature in drying box it is constant.
The outlet of described heating coil 4 is provided with drain valve 8, and the water of condensation is discharged from drain valve, avoids heating coil
In condensation dilutional hyponatremia the problem of causing heating effect difference.
Described hot-rolling unit includes the support base 22 being arranged in drying box, and the side of support base 22 is provided with multiple heat
Roller 21, described hot-rolling are the hollow roll body of one end open, and heater is provided with inside roll body, and conventional heater is electricity
Magnetic response heater or steam heater.
The utility model has the advantages that：
The utility model sets heating coil in drying box, and the environment temperature in drying box is adjusted, made
Carbon fiber precursors are dried under conditions of relatively constant temperature, overcome environment temperature and heat in the prior art in drying box
There is the problem of fiber quality stability difference that the temperature difference is brought in roll temperature, so as to reach good drying effect, reduce fibroid
Can discreteness, reduce lousiness, improve the long-range stability of fibre property, for the later stage aoxidize carbonisation stable operation and
Stable performance lays the foundation.
