Abstract
The present invention provides a high strength and high modulus polyethylene fiber double duct drawing hot box. A working channel with with one end provided with a fiber filament bundle inlet opening and an air inlet opening and the other end provided with a fiber filament bundle outlet opening and an air outlet opening is arranged in a box body, an upper air duct and a lower air duct with the both ends respectively provided with an air inlet opening and an air outlet opening are evenly arranged at the upper part and the lower part of the working channel, and the air inlet opening and the airoutlet opening of the upper air duct and the lower air duct are respectively and mutually connected with the air outlet opening and the air inlet opening of the working channel. A blower, an equalizer, and a heater are evenly arranged in the upper air duct and the lower air duct. A wind flow conditioning plate is arranged at the position of the air inlet opening of the working channel. A plurality of arc flow guide plates are arranged in an arc curved channel at the air outlet opening position of the upper air duct and the lower air duct. Staggered wind guide plates are arranged in the heater. Because the present invention additionally is provided with the upper air duct, and additionally provided with a wind direction adjusting plate and the flow guide plate, and the wind guide plates are arranged in the heater, the wind direction and the wind speed of hot air are improved, the heating uniformity is increased, the heating drawing effect of the fiber filament bundle is enhanced, and the product quality is guaranteed.
Description
Technical field
The present invention relates to a kind of drawing of fiber heater, particularly a kind of high-module high-strength polyethylene fibre drafting heat box.
Background technology
Drafting heat box is a kind of indispensable device of producing in the high-module high-strength polyethylene fibre process, and it can be with the heating of fibre bundle limit, limit drawing-off.Existing drafting heat box, be provided with one one end in its casing and be provided with the service aisle that tow import and air inlet, the other end are provided with tow outlet and air outlet, below service aisle, be provided with two ends and set up the air channel of air inlet and air outlet separately, be provided with blower fan, voltage balancer and heater in the air channel, the air inlet in air channel and air outlet interlink with the air outlet and the air inlet of service aisle respectively.Fibre bundle is walked from service aisle, and by the hot blast that heater and blower fan provided in the air channel to the tow heating that circulates.Because the length of drafting heat box is long and the heat radiation of heater, the temperature difference very easily occurs at the two ends of service aisle, wind speed, air quantity and wind direction also skewness in service aisle has so just influenced heating, drawing-off effect and the product quality of tow.
Summary of the invention
For overcoming the deficiencies in the prior art part, the invention provides a kind of high-module high-strength polyethylene fibre drafting heat box of rational in infrastructure, homogeneous heating.
The technical solution adopted for the present invention to solve the technical problems is: on existing drafting heat box basis, and the upper air duct of the identical configuration in air channel below being provided with above the service aisle with it.Specifically: be provided with an end in its casing and be provided with fibre bundle import and following air inlet, the other end and be provided with that fibre bundle exports and the service aisle of following air outlet, below service aisle, be provided with two ends and set up the lower air duct of air inlet and air outlet separately, the air inlet of lower air duct and air outlet interlink with the following air outlet of service aisle and following air inlet respectively, are provided with blower fan, voltage balancer and heater in lower air duct; It is characterized in that: above service aisle, be provided with the upper air duct that two ends are set up air inlet and air outlet separately, the air inlet of upper air duct and air outlet interlink with the last air outlet and the last air inlet of service aisle respectively, are provided with blower fan, voltage balancer and heater in being in the wind.
Upper and lower air inlet place at service aisle is equipped with wind direction adjusting plate, so that regulate the wind direction that enters the hot blast in the service aisle, and the refraction angle of hot blast in service aisle, make the heating of fibre bundle more even.
In the air outlet place arc bend in last, air channel, be provided with its corresponding arc deflector of several piece, with overcome hot blast directly hit wall produce refraction and make wind direction indefinite, cause the uneven problem of heating in the service aisle.
In above-mentioned heater, be provided with staggered wind deflector, make hot blast fully heating in heater, reduce the temperature difference of hot blast, improve the thermal efficiency, play all pressure effects simultaneously.
The invention has the beneficial effects as follows: owing to above service aisle, set up upper air duct, and be provided with wind direction adjusting plate at the place of air inlet up and down of service aisle, set up deflector at the arc bend place of last lower air duct, and in heater, set up wind deflector, thereby wind direction, the wind speed of hot blast have been improved, increased the uniformity of heating, improve the heating drawing-off effect of fibre bundle, guaranteed product quality.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Among the figure: 1 for casing, 2 for service aisle, 2-1 be fibre bundle import, 2-2 be fibre bundle outlet, 2-3 be last air inlet, 2-4 for air inlet, 2-5 down be last air outlet, 2-6 for air outlet down, 3 for upper air duct, 4 for lower air duct, 3-1 and 4-1 be air outlet, 3-2 and 4-2 be air inlet, 5 for wind direction adjusting plate, 6 for arc deflector, 7 for blower fan, 8 for voltage balancer, 9 for heater, 9-1 be wind deflector.
