Embodiment 1

[0046] On the one hand, this embodiment discloses an extraction machine for high-strength and high-modulus polyethylene fibers, see figure 1 , which includes an extraction tank 110, an inlet roller 120, an outlet roller 130, a guide roller and a drive unit, wherein:

[0047] The extraction tank 110 is an open container that can hold the extractant inside the opening at one end;

[0048] The inlet roller 120 and the outlet roller 130 are rotatably installed on two opposite inner walls of the extraction tank 110 respectively. The as-spun fiber 500 enters the extraction tank 110 after being wound on the inlet roller 120, and is passed through after being wound on the outlet roller 130. The extraction tank 110 is exported;

[0049] The guide roller 140 is rotatably installed in the extraction tank 110, and the inlet roller 120, the outlet roller 130 and the guide roller 140 are arranged in parallel, so that a plurality of as-spun fibers 500 enter the extraction tank 110 through t...

Embodiment 2

[0053] On the basis of Embodiment 1, the extraction machine 100 further includes a rectangular frame 161 , the four corners of the frame 161 are adjustable in height from the ground, and the extraction tank 110 is fixed on the frame 161 . For the consideration of installation and use environment, the extraction tank 110 should not be placed directly on the ground, especially if the level accuracy of the ground is not enough or there are assembly errors between the inlet roller 120, the guide roller 140 and the outlet roller 130 and the extraction tank 110, It will cause the overall inclination of the inlet roller 120, the guide roller 140, and the outlet roller 130, thereby causing the entanglement of the nascent fiber 500. Therefore, the occurrence of the above phenomenon should be avoided. Therefore, the inventor installed the extraction tank 110 on the frame 161, by adjusting the height of the four corners of the frame 161 from the ground to ensure the horizontal accuracy of...

Embodiment 3

[0064] On the basis of Embodiment 1 or 2, the extraction machine 100 of this embodiment also includes a driven guide roller 150 that is rotatably installed in the extraction tank 110 and whose axis direction is parallel to the axis direction of the guide roller 140. The number is equal to the number of driven guide rollers 150 and is at least two. The guide rollers 140 and the driven guide rollers 150 are respectively arranged at two opposite ends of the extraction tank 110 so that the guide rollers 140 and the driven guide rollers are bypassed. The as-spun fibers 500 of the roller 150 can be turned back several times in the extraction tank 110, thereby ensuring the soaking length of the as-spun fibers 500, so that the height and width of the extracting tank 110 can be greatly reduced under the premise of ensuring the same soaking length, so that the extraction tank It is possible to design 110 as a horizontal tank, thereby reducing equipment manufacturing costs, reducing the s...

Abstract

The invention discloses an extraction machine and extraction device for a high-strength and high-modulus polyethylene fiber. The extraction machine comprises an extraction tank, a wire feeding roller,a wire discharging roller, a guiding roller and a driving unit, wherein the extraction tank is an opened container with an opening at one end and can accommodate an extracting agent; the wire feedingroller and the wire discharging roller are respectively and rotationally mounted on two opposite inner walls of the extraction tank; the guiding roller is rotationally mounted inside the extraction tank; the wire feeding roller, the wire discharging roller and the guiding roller are arranged in parallel; the height of the guiding roller is smaller than that of the wire feeding roller; the heightof the guiding roller is smaller than that of the wire discharging roller; the driving unit is mounted on a groove body; and a transmission unit drives the guiding roller to rotate through the transmission unit. The extraction machine and the extraction device have the benefits that the extracting agent is effectively recovered; the horizontal precision of the guiding roller is high, so that the entanglement of a primary fiber is avoided and the quality of a finished fiber is ensured; due to the use of sliding bearings, the replacement frequency of the bearings is reduced; the concentration and the temperature of the extracting agent can be automatically adjusted; and the concentration gradient of the extracting agent is arranged to improve the extraction effect.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to an extraction machine and an extraction device for high-strength and high-modulus polyethylene fibers. Background technique [0002] High-strength high-modulus polyethylene fiber Polyethylene fiber is the third-generation special fiber in the world today, with a strength of up to 30.8cN / dtex, the highest specific strength among chemical fibers, and good wear resistance, impact resistance, corrosion resistance, and light resistance. . It can be directly made into ropes, cables, fishing nets and various fabrics: bulletproof vests and clothes, cut-resistant gloves, etc., among which the bulletproof effect of bulletproof vests is better than aramid. Internationally, high-strength and high-modulus polyethylene fibers have been woven into ropes of different deniers, replacing traditional steel cables and synthetic fiber ropes. High-strength high-modulus polyethylene fiber ...
