A cooling device and method for spinning polyester with ring blowing

Abstract

The invention discloses a circular blowing polyester spinning cooling device. The device is composed of two parts, namely a blowing device and air-conditioning systems; the blowing device comprises a frame, a lifting cylinder, a lifting rod, a first air inlet pipe, a second air inlet pipe, a first air duct, a second air duct and a guide duct; a first annular cavity is arranged outside the first air duct, while a second annular cavity is arranged outside the second air duct and a third annular cavity is arranged outside the third guide duct; a first annular air equalizing cover is arranged outside the first annular cavity, while a second annular air equalizing cover is arranged outside the third annular cavity; the inlet pipeline of the first annular air equalizing cover is communicated with the first air inlet pipe; the inlet pipeline of the second annular air equalizing cover is communicated with the second air inlet pipe; the first air-conditioning system provides the first air inlet pipe with cooling air, while the second air-conditioning system provides the second air inlet pipe with cooling air. According to the circular blowing polyester spinning cooling device, a circular blowing cooling manner is adopted, air can be fed in each direction so that nascent fibers can be evenly cooled in each direction, and meanwhile, the upper and lower layers of circular blowing are evener, and the fiber cooling effect is good.

Description

technical field

[0001] The invention relates to the field of polyester production, in particular to a cooling device and method for polyester spinning with air circulation. Background technique

[0002] Spinning cooling devices for polyester production are divided into side blowing cooling devices and ring blowing cooling devices. The present invention refers to ring blowing cooling devices. The closest prior art is ZL201220462989.4, a new type of ring blowing device. The ring blowing device adopts the method of uniform air in the vertical direction to make the ring air more uniform, but only in the vertical direction, and there is no air uniform measure in the horizontal direction, that is to say, the side of the wind speed close to the air inlet pipe is relatively far away from the side of the air inlet pipe One side is big, because there is above-mentioned technical problem in prior art, therefore must improve.
