Description
Technical Field
The invention relates to an extraction method for fiber production.
Background
The extraction method of white oil in gel wires in the wet polyethylene fiber production process is generally a groove-type extraction process, and the gel wires are immersed in an extraction groove containing an extraction agent through a pneumatic or oil pressure system to perform extraction.
Disclosure of Invention
The invention aims to provide an extraction method for producing fibers, which can realize high-efficiency extraction and is beneficial to stable product quality.
The technical solution of the invention is as follows:
an extraction method for fiber production is characterized in that: comprises the following steps: the PE gel filaments from pre-drawing sequentially pass through a primary extraction box, a secondary extraction box, a tertiary extraction box and an … … N-level extraction box and then enter a drying box to be blown off and recover the carried extractant; each stage of extraction box is provided with a roller immersed in the extraction liquid; a turning transition roller is arranged between the adjacent two-stage extraction tanks, the transition roller is higher than the liquid level of the extraction tanks, and most of solution contained in the filaments is removed through drafting; the flow direction of the extracting agent is opposite to the advancing direction of the gel silk, the extracting agent sequentially flows through an N-stage extraction box, a (N-1) stage extraction box … … secondary extraction box and a primary extraction box, and finally is collected to an extracting solution collecting tank and is conveyed to a solvent treatment section by an extracting solution pump.
Each stage of extraction box is provided with a reinforced extraction liquid disturbance device (a stirring device and the like). The bottom of each stage of extraction tank is provided with a drain valve.
The roller immersed in the extraction liquid is movable up and down or fixed.
The invention can realize high-efficiency extraction and is beneficial to the stable product quality; its advantage still lies in:
1. each stage of extraction box can be provided with an extraction liquid disturbance strengthening device for stirring and the like, so that the extraction effect is improved.
2. The bottom of each stage of extraction box is provided with a drain valve to facilitate liquid drainage and maintenance in case of failure.
3. The fault of any single-stage extraction box can realize effective isolation without influencing the continuous and stable production of the PE fiber.
4. The PE jelly glue silk is drawn at intervals of dry and wet along the flow direction, which is equivalent to increase the extraction stage number and is beneficial to removing the white oil from the jelly glue silk.
5. The roller immersed in the extraction liquid in each stage can be movable (up-down movable) or fixed, and the immersion depth of the gel silk can be adjusted according to requirements (realized by adjusting the liquid level height in the tank of each stage, and if the roller immersed in the extraction liquid is movable, the immersion depth can also be realized by operating a transmission mechanism of the movable roller).
6. Compared with movable immersion extraction, the fixed rotary roller has better production stability for PE fibers.
7. The occupied area is small, and the investment is small.
8. The whole is broken into parts, so that the volatile gas is convenient to collect.
9. The portable movable and visible organic glass is used as the partition plate, so that the production monitoring and the inspection and maintenance are facilitated.
10. The concentration (white oil concentration) of the discharged liquid of each stage of extraction box can be monitored in real time, so that the liquid inlet amount of the extraction liquid and the drafting speed of the PE fibers can be reasonably adjusted, the optimal state is obtained, and the maximum benefit is ensured.
