Embodiment 1

[0079] Such as Figure 3-12 As shown, this embodiment provides a dual-row synthetic tow cooling system, which includes a spinning device and a dual-row synthetic tow cooling device. Among them, such as Figure 3-6 As shown, the spinneret includes a spinneret 500 and a closed channel that connects the spinneret 500 and the wire mesh cylinder 103 installed in the cooling box 100 in a sealed manner. The number of the above-mentioned closed channels is the same as the number of the spinneret 500 and the silk screen tube 103, and they are set independently; because the temperature of the spinneret 500 is relatively high when working, in order to reduce heat conduction, avoid passing through the above-mentioned closed channel and the spinneret The temperature of the cooling box 100 connected to the 500 increases to reduce its cooling effect. A heat shield is also provided between the spinneret 500 and the closed channel. The polymer melt trickle 501 ejected from the spinneret 500 ent...

Embodiment 2

[0098] This embodiment provides a dual-row synthetic tow cooling system, which is a modification on the basis of embodiment 1, such as Figure 13 with Figure 14 As shown, in this embodiment, the wall structure of the cooling box 100 is different from that of Embodiment 1. Specifically, the cooling box 100 is a shell, and the shell includes a horizontal inner wall 100c and a horizontal inner wall 100c. At least one inclined inner wall 100d connected to 100c, a plurality of rows of the wire mesh cylinders 103 are respectively arranged parallel to the horizontal inner wall 100c, the wire mesh cylinders 103 of adjacent rows are staggered, and the rows of different rows close to the inclined inner wall 100d A line connecting the centers of a plurality of adjacent wire mesh cylinders 103 forms a straight line, the inclined inner wall 100 d is arranged substantially parallel to the straight line, and the inclined inner wall 100 d and the porous plate 201 intersect at a hypotenuse 107. ...

Embodiment 3

[0101] This embodiment provides a dual-row synthetic tow cooling system, which is a modification on the basis of Embodiment 1. In this embodiment, as Figure 15 As shown, the means for reducing the amount of cold air entering the first circulation space A through the ventilation holes 111 per unit time is different from that of Embodiment 1. In this embodiment, by changing the perforated plate 201 The arrangement of the ventilation holes 111 changes the amount of cold air entering the first circulation space A, specifically, the density of the ventilation holes 111 on the porous plate 201 opposite to the first circulation space A Less than the density of the ventilation holes 111 on the perforated plate 201 opposite to the other circulation space B, so that the amount of cold air in the first circulation space A is equal to the amount of cold air in the other circulation space B Basically the same.

[0102] Here, "substantially the same" should be understood to mean that in a un...

Abstract

The invention provides a multi-row synthetic tow cooling system which comprises a spinneret device, a cooling box and an air supplying device used for supplying cold air into the cooling box. Multiple rows of air tube assemblies used for passing of tows are arranged on the cooling box, a multi-hole plate is arranged between the cooling box and the air supplying device, and a plurality of ventilation holes are formed in the multi-hole plate. The cold air from the air supplying device enters the outsides of silk screen tubes in the air tube assemblies through the ventilation holes and enters the insides of the silk screen tubes from the outer circumferences of the silk screen tubes, polymer melt trickles jetted by the spinneret device is cooled to be filaments, circulation spaces formed at the outer circumferences of the silk screen tubes are communicated with the same rows of adjacent silk screen tubes, the different rows of adjacent silk screen tubes and different inner walls of the cooling box, and differential values between air pressure of the cold air at different positions in the circulation space and air pressure of the insides of the silk screen tubes are basically accordant through control over the cold air amount at the different positions in the circulation space.

Description

Technical field [0001] The invention relates to a cooling system for multiple rows of synthetic tows, belonging to the technical field of synthetic tow cooling. Background technique [0002] In the production of synthetic tow, the thin stream of polymer melt sprayed from the micro holes of the spinneret is forced to cool by blowing cold air in the cooling device, and it is condensed and solidified into filaments in a short time. The wind pressure and wind speed of the cold air in the cooling device have a great influence on the uniformity of the filaments formed after the condensation and solidification of the polymer melt stream. The above-mentioned uniformity mainly refers to the diameter, strength, and elongation of the filament. Therefore, maintaining the uniformity and stability of the external cooling conditions (mainly controlling the uniformity and stability of the wind speed) is very important for spinning high-quality filaments.
