Embodiment 1

[0015] Such as figure 1 The shown impregnation device for the preparation of heat-resistant and creep-resistant polyethylene fibers includes an impregnation container 1, a transfer roller 2 for transferring polyethylene fibers is arranged inside the impregnation container 1, and an impregnation container 1 is arranged on the impregnation container 1. The liquid inlet 3 and the immersion liquid outlet 4, wherein the immersion liquid outlet 3 is arranged on the side end surface of the immersion container 1; the inside of the immersion container 1 is provided with a stirring device, which includes a stirring shaft 5 and a stirring blade 6; Two immersion liquid storage containers 7 are provided outside the immersion container, which are connected to each other, wherein any one of the immersion liquid storage containers 7 is connected with an overflow pipe 16 extending into the inside of the immersion container 1; There is an auxiliary stirring device, which includes an auxiliary st...

Embodiment 2

[0020] As an improvement of the present invention, the height position of the immersion liquid outlet 4 is higher than the height position of the transfer roller 2, and the height distance between them is at most 10 cm.

[0021] The remaining features and advantages of this embodiment are the same as those of the first embodiment.

Embodiment 3

[0023] As an improvement of the present invention, in the impregnation vessel 1, the stirring shaft 5 extends in the vertical direction, and two guide shafts 12 extending in the horizontal direction are provided on the side end surface of the impregnation vessel 1. A plurality of guide vanes 13 are arranged on one guide shaft 12; two guide shafts 12 are respectively arranged on both sides of the polyethylene transmission position; the guide shaft 12 passes through a guide motor arranged outside the immersion container 1 14 is driven; the bottom end of the immersion container 1 is provided with a hydraulic pump 15. By adopting the above technical solution, it can form a radial liquid flow on both sides of the polyethylene transmission position, so that the impregnation effect of the polyethylene fiber can be improved.

[0024] The remaining features and advantages of this embodiment are the same as those of the second embodiment.

Abstract

The invention discloses an impregnation device for heat-resistant creep-resistant polyethylene fiber preparation. By means of the device, in a preparation and processing process of polyethylene fibers, impregnation processing treatment can be conducted on the polyethylene fibers though an impregnation container; in an actual work process of the impregnation device for heat-resistant creep-resistant polyethylene fiber preparation, conveying treatment can be conducted on the polyethylene fibers through conveying rollers, and by means of an impregnation liquid inlet and an impregnation liquid outlet in the upper portion of the impregnation container, adjustment of the liquid level of impregnation liquid in the impregnation container can be achieved, so that it is ensured that the impregnationliquid is always maintained to be over the polyethylene fibers. By means of a stirring container in the impregnation container and an auxiliary stirring container in an impregnation liquid storage container, stirring treatment can be conducted on the impregnation liquid in the impregnation container and impregnation liquid which is exported into the impregnation liquid storage container simultaneously, so that the whole impregnation effect is guaranteed.

Description

Technical field [0001] The invention relates to the field of textile engineering, in particular to an impregnation device for preparing heat-resistant creep-resistant polyethylene fibers. Background technique [0002] As a common fiber material, polyethylene fiber is widely used in fabrics in various fields. Among them, ultra-high molecular weight polyethylene fiber, as a fiber material with excellent specific strength and specific modulus, is used in military, aerospace, and other special Widely used in the field. At present, the preparation of ultra-high molecular weight polyethylene fibers mainly includes processes such as extrusion, spinning, spinning, extraction, drying, heating and drawing, and winding molding. However, the ultra-high molecular weight polyethylene fibers prepared by existing processes Due to its unsatisfactory mechanical or optical properties, it needs to be impregnated to make the impregnating medium enter the polyethylene fiber. However, the existing po...
