Description

A kind of Sheng silk device that is used to hold ultra-high molecular weight polyethylene gel fiber

Technical field

The utility model relates to a kind of Sheng silk device that is used to hold ultra-high molecular weight polyethylene gel fiber in superhigh molecular weight polyethylene fibers production.

Background technology

Superhigh molecular weight polyethylene fibers (UHMWPE) is a kind of high-performance fiber of succeeding in developing and entering the beginning of the eighties industrialization end of the seventies in last century, with carbon fiber, aramid fiber and be called the world today's three big tec fibers, mainly at present produce by the gel spinning method.In the prior art, the key step of gel spinning method is as follows: ultra-high molecular weight polyethylene is joined in the suitable solvent stirring and dissolving make solution, this solution is extruded by screw extruder, through the spinneret orifice moulding, cool off then, extraction, drying, behind ultra-drawing, obtain finished fiber.Wherein, described drying process carries out in the bottom has the casing of liquid outlet, in order to guarantee that gel fiber can dryly quickly reach balance time with the nascent gel spun fiber of shortening, the amount of holding of the gel fiber in each casing is restricted, and causes the consumption of casing big.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of improved Sheng silk device to reach balance time and improve the silk amount of containing to shorten nascent gel spun fiber.

For solving above technical problem, the utility model adopts following technical scheme:

A kind of Sheng silk device that in superhigh molecular weight polyethylene fibers production, is used to hold ultra-high molecular weight polyethylene gel fiber, it comprises the casing that is used to provide the required accommodation space of described ultra-high molecular weight polyethylene gel fiber, be arranged on the case lid of casing top, the bottom of described casing offers the liquid outlet that is used to discharge liquid, be provided with first valve at the liquid outlet place, described Sheng silk device comprises that also along continuous straight runs is arranged in the described casing and described casing is divided into the dividing plate of a plurality of Sheng cabinets, described dividing plate is more than two, and is evenly distributed with a plurality of through holes on dividing plate.

According to a preferred aspect of the present utility model, described case lid is tightly connected mutually with casing.On the top of casing or case lid, be provided with vacuum orifice, be provided with second valve, can connect vacuum extractor, so can make to be in vacuum state in the casing, quicken the rate of drying of gel fiber by this second valve at this vacuum orifice place.

According to a concrete aspect of the present utility model, described casing is a cuboid, dividing plate is a rectangle, two long limits of described dividing plate are connected with the inwall of casing respectively, thereby and the length on the long limit of casing make that less than the length of casing the formation space prevents that the gel fiber between two adjacent described Sheng cabinets is pressed down between the inwall of the minor face of described dividing plate and casing.

According to the utility model, can also roller be set in the bottom of casing so that contain moving of silk device.

Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:

By cavernous dividing plate is set in casing casing is divided into a plurality of Sheng cabinets, the silk amount that holds of then containing silk device grows proportionately, thereby can reduce the consumption of containing silk device in the production process, saves cost and space.In addition, the utilization of cellular dividing plate makes that also the contraction of gel fiber is more even, the back hot drawing-off in road is more stable, thereby can reduce the denier irregularity of finished fiber, improves the finished fiber quality.

Description of drawings

The utility model is described in more detail below in conjunction with accompanying drawing and concrete embodiment:

Fig. 1 looks cross-sectional schematic (casing does not cut open) for a master according to Sheng silk device of the present utility model;

Fig. 2 is for overlooking cross-sectional schematic (dividing plate does not cut open) according to of Sheng silk device of the present utility model;

Wherein: 1, casing; 2, case lid; 3, dividing plate; 4, first valve; 5, second valve; 6, roller; 7, space; 10, liquid outlet; 11, vacuum orifice; 12, contain cabinet; 30, through hole.

The specific embodiment

As depicted in figs. 1 and 2, according to the Sheng silk device of present embodiment mainly comprise cuboid casing 1, be arranged on dividing plate 3 in the casing 1, case lid 2 that sealing is arranged on casing 1 top, first valve 4 at liquid outlet 10 places of the bottom that is arranged on casing 1, be arranged on second valve 5 at vacuum orifice 11 places on the case lid 2 and the roller 6 that is arranged on casing 1 bottom.Dividing plate 3 every being divided into three Sheng cabinets 12 that are used to hold polyethylene eastern suburb silk, has a plurality of through holes 30 with the inner space of casing 1 on the dividing plate 3, and forms space 7 between the inwall of the both ends of dividing plate 3 and casing 1.Casing 1, case lid 2 and dividing plate 3 all adopt 304 stainless steels, realize sealing by silica gel or other encapsulant between case lid 2 and the casing 1.

It is as follows to utilize the utility model to hold the process of polyethylene gel fiber: close first valve 4, gel fiber drops on earlier on the dividing plate 3 of the bottom, fall after a period of time, gel fiber falls on second dividing plate 3, successively up, the silk that falls finishes, and covers case lid 2, second valve 5 is linked to each other with vacuum extractor, leave standstill.Between resting period, can open the liquid after first valve 4 is separated with release.

To sum up, be three times of common Sheng silk device according to the Sheng Siliang of the Sheng silk device of present embodiment, consumption that can significantly less Sheng silk device is saved cost and is saved the space.In addition, the Sheng silk device of employing present embodiment has also shortened nascent gel spun fiber greatly and has reached balance time, and the production cycle of superhigh molecular weight polyethylene fibers is shortened; And because the utilization of porous barrier plate, the contraction of gel spun fiber is more even, and the hot drawing-off in back road is more stable, thereby can reduce the quality of the irregularity and the raising product of finished product fibre number.

More than the utility model has been done detailed description; its purpose is to allow the personage that is familiar with this art can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to spiritual essence of the present utility model change or modify, and all should be encompassed in the protection domain of the present utility model.
