Problems solved by technology

[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 large, due to the above-mentioned technical problems in the prior art, it must be improved

Embodiment 1

[0028] Such as figure 1 , 2 , 3, and 4, the ring air blowing polyester spinning cooling device described in this embodiment is composed of two parts: a blowing device 1 and an air conditioning system 20, and it is characterized in that the described blowing device 1 includes a frame 2, a lifting cylinder 3. The lifting rod 4, the first air inlet pipe 5, the second air inlet pipe 6, the first air cylinder 7, the second air cylinder 8 and the guide cylinder 9, the first air cylinder 7 and the second air cylinder 8 can be ventilated, The guide cylinder 9 is airtight; the lift cylinder 3 is arranged on the frame 2, the bottom of the lift rod 4 is connected to the lift cylinder 3, the top is connected to the outer wall of the guide cylinder 9, the first air inlet pipe 5 and the second air inlet pipe 6 Also located on the frame 2, the first air inlet pipe 5 and the second air inlet pipe 6 are provided with a deformation section 10 and an air inlet valve 19, and the first air cylind...

Embodiment 2

[0033] Such as Figure 5 As shown, the ring-air blown polyester spinning cooling device described in this embodiment is different from Embodiment 1 in that: the first air conditioning system 21 and the second air conditioning system 22 have the same structural composition, and they are all composed of sequentially connected Air duct 23, air intake fan 24, air intake valve 25, coarse filter 26, preheater 27, front surface cooler 28, spray chamber 29, rear surface cooler 30, rear heater 31, blower 32 , fine filter 33 and air outlet 34 are formed.

Embodiment 3

[0035] Such as Figure 6 As shown, the difference between the circulating blowing polyester spinning cooling device described in this embodiment and the embodiment 1 is that the cooling air blown out by the first air cylinder 7 blows obliquely upwards. The cylinder body of the first air cylinder 7 is covered with through holes 35 inclined inwardly and upwardly, and the angle of inclination of the through holes 35 is 30 degrees (the angle of inclination of the through holes 35 can be selected from 30 degrees to 60 degrees. ), the first air inlet 17 is a horizontal air intake, of course, the first air inlet 17 is also inclined inwardly and upwardly, so that before entering the first air cylinder 7, the cooling air experiences an oblique upward direction, and blows obliquely upward The effect is better. The surrounding air blown out by the first air duct 7 is blown upward obliquely. When the primary fiber is ejected, it goes down at a high speed. In the prior art, the cooling ai...

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. Contents of the invention [0003] The object of the p...
