Technical field
The utility model belongs to chemical fibre preparing technical field, is applied more particularly to one kind in chemical fibre drawing process
Air-cooled shaped device.
Background technology
Chemical fibre is as a kind of staple fibre, and it has extremely wide purposes, and the material for preparing chemical fibre is by various raw materials
Mix what is formed by certain proportioning.The form of raw material has powdery or graininess, and the material of these forms needs to add by high temperature
Heat is melted into liquid.Material is formed thread, it is necessary to be prepared by the air-cooled shaped device of wire drawing.Existing shaped device
Including die head above and underlying air cooled box, some open-works are provided with die head, the material after liquefaction is via die head
Interior open-work outflow.Reel is provided with below air cooled box, reel is while play the winding effect to shaping silk, on one side
Traction drawing is carried out to silk.To carry out watching treatment, the front openings of air cooled box to the silk in die head out, administrative staff pass through
Opening can be monitored and make some necessary operations to silk just out, in order to avoid be bonded between silk.
The air cooled box of this shaped device takes the mode that natural wind cools down to silk progress natural cooling, and prepared by chemical fibre
Actual environment is interior, and environment is relatively closed, and with the progress of production, indoor temperature can change rise, therefore the one of silk
The uniformity of a little physical characteristics is relatively poor.Moreover, when temperature is too high indoors, just silk out is not easy quickly to cool down, and this is just
So that between solidifying halfway silk easily bonding, it is necessary to administrative staff be frequently utilized that instrument carry out silk between separate, administrative staff's
Workload is big.It is of course also possible to set air-conditioning system indoors to realize the cooling of interior, but this can increase the construction of factory building into
This, and the energy consumption of air-conditioning system is also high, and air-conditioning system is provided with its limitation.
