Description
Technical field
The invention belongs to chemical fibre manufacturing technology field, particularly relate to and need in process of production to use extracting process to remove the solvent-laden fibre abstraction device of institute and fiber multitple extraction device in fiber.
Background technology
In chemical fiber preparation industry, there is few fibers can only be produced by solwution method spinning, such as viscose, polyacrylonitrile fibre, high-tenacity polyethylene fibre, alginate fibre etc.In these fiber producing process, few fibers is had to need to remove contained solvent in as-spun fibre, such as above-mentioned high-tenacity polyethylene fibre and medical alginate fibre by extracting process.
In general, extraction needs to consider effect of extracting and extraction cost, be specially extract time of staying (i.e. extraction time) in extractant as far as possible long, and the ratio of extract and extractant (i.e. extraction bath ratio) is high as far as possible.Volume based on the above-mentioned purpose extraction equipment designed traditionally is too large, and cost is high.Such as be fabricated to example with medical alginate fibre: in alginate fibre is produced, general spinning speed, at more than 10m/min, if consider effect of extracting and cost, is supposed to be divided into three grades of extractions, every grade of time of staying is only 1min, then required extraction tank total length will reach more than 30m; And the fibre weight of a branch of 10m length is only at about 20g, its cross-sectional area is less than 0.5cm
2, therefore extraction tank sectional area is designed to 5cm
2just more than sufficient.Obviously, not only thin but also long according to the equipment of such parameter designing, very inapplicable actual production.
Chinese patent CN201098564A, August 13 2008 publication date, disclose a kind of high-strength high-modulus polyethylene fibre multi-stage continuous extraction machine, in this extracter in each extraction cell, fiber is entered downwards bottom extraction cell by extraction cell upper end by godet roller, upwards derived from extraction cell opening by godet roller again, and then enter next extraction cell.This device increases the walking distance of fiber in each extraction cell by changing fiber orientation in each extraction cell, but because each godet roller all axially be arranged in parallel, therefore mass of fibers tow can only form a Ge Si road on godet roller, walking distance is still limited, so the effect of extracting in order to reach expection, extraction cell number can only be increased, but which adds cost, and the silk between each godet roller will be allowed to produce tension force, after must making, the rotating speed of a roller is a little faster than last roller, but need the speed difference between every two rollers to be fixing, if godet roller quantity is many, be difficult to realize the equal control of speed difference, also the cost of device is relatively added, and expection effect of extracting will be reached, extraction cell quantity will be increased according to the above analysis, namely increase godet roller quantity, also Solvent quantity can be increased, these also all can cause cost to raise.
In addition, Chinese patent CN201190199A, February 4 2009 publication date, disclose an extraction equipment for the production of polyethylene fiber and multitple extraction device, the spaced godet roller of design two row in an extraction tank in the apparatus, fiber, successively alternately through these godet rollers, makes fiber walk up and down in every one-level extraction tank "the" shape.This patent and above-mentioned patent have Similar Problems, namely can only form a Ge Si road between every two godet rollers, and can only increase the walking distance of silk by increasing godet roller quantity, cause godet roller quantity many, extraction cell volume is large, and wayward, cost is very high.
In view of this, special proposition the present invention.
