Embodiment 1

[0033] like figure 1 , the above-mentioned pair of guide wire rollers are respectively cylindrical or cylindrical equal-diameter rollers, and a pair of guide wire pair rollers are arranged in the extraction chamber, and the pair of guide wire pair rollers are the first roller 5 and the second roller 4, and the two rollers There is an included angle between the axes, and the included angle is an acute angle. In this way, the incoming wire will be automatically divided into multiple wire paths, so that the utilization rate of the godet rollers can be improved, and the amount of godet rollers can be reduced while achieving the same extraction effect. The volume of the extraction device reduces the cost, simplifies the structure, and increases the extraction bath ratio. Moreover, because the number of rollers is small, and the tension between the two can be automatically generated by the inclination angle, it is easy to control.

[0034] When in use, the extraction chamber 1 is fi...

Embodiment 2

[0044] In the above-mentioned embodiment 1, the second roller 4 can be disassembled to adjust the inclination angle, or in order to facilitate the adjustment of the angle between the two rollers, an angle adjustment device can be configured for the second roller 4, so that the second roller 4 can be adjusted without removing the second roller 4. angle.

Embodiment 3

[0046] Different from Example 1, it can be as figure 2 Let the first roll 5 be an equal-diameter roll as shown, and the second roll 4 be a truncated conical roll, so that the distance between the two roll surfaces will gradually decrease from the installation end to the end. In this embodiment, there is no need to set an included angle between the two rollers, that is, the axes of the first roller 5 and the second roller 4 are parallel to each other, and the installation process is simpler.

[0047] Alternatively, the second roll 4 is an equal-diameter roll, the first roll 5 is a truncated conical roll, and the axes of the first roll 5 and the second roll 4 are parallel to each other.

[0048] The present invention mainly utilizes the principle that the distance from the installation end 11 of the extraction chamber to the end 12 of the extraction chamber on the outer edge of the rotating surface gradually decreases between the two godet rollers so that the fiber filaments ar...

Abstract

The invention discloses a fiber extraction device and a fiber multi-stage extraction device, which comprises a motor and an extraction room (1), a small godet is arranged at a fiber inlet opening and a fiber outlet opening of the extraction room respectively, an extraction agent injection opening is formed in the side wall of the fiber outlet side of the extraction room, and an overflow opening is formed in the side wall of the fiber inlet side. The device provided by the invention is characterized in that one or more pairs of godets are arranged inside the extraction room, and the distance between each pair of godets is reduced from the mounting end (11) of the extraction room to the periphery of the rotation surface at the tail end (12) of the extraction room. According to the device, same extraction effect can be achieved while the number of the utilized godets is reduced, the volume of the extraction room is reduced, and the cost is lowered; the device is easy to control.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber manufacturing, and in particular relates to a fiber extraction device and a fiber multistage extraction device which need to use an extraction method to remove solvent contained in fibers during the production process. Background technique [0002] In the chemical fiber manufacturing industry, some fibers can only be produced by solution spinning, such as viscose fiber, polyacrylonitrile fiber, high-strength polyethylene fiber, seaweed fiber, etc. During the preparation of these fibers, some fibers need to be extracted to remove the solvent contained in the primary fibers, such as the above-mentioned high-strength polyethylene fibers and medical seaweed fibers. [0003] Generally speaking, extraction needs to comprehensively consider the extraction effect and extraction cost. Specifically, the residence time of the extracted substance in the extractant (ie, the extraction time) should be as...
