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 [0001] The invention relates to a fiber drawing heating device, in particular to a high-modulus high-strength polyethylene fiber drawing heating box. Background technique [0002] The drawing hot box is an essential device in the process of producing high-modulus and high-strength polyethylene fibers. It can heat and draw the fiber tow. In the existing drafting hot box, there is a working channel with a tow inlet and an air inlet at one end and a tow outlet and an air outlet at the other end in the box, and an air inlet at both ends under the working channel. and the air duct of the air outlet, a fan, a pressure equalizer and a heater are arranged in the air duct, and the air inlet and the air outlet of the air duct communicate with the air outlet and the air inlet of the working channel respectively. The fiber tow passes through the working channel, and the tow is circulated and heated by the hot air provided by the heater and the fan in the air channel. D...
