Problems solved by technology

Although biological degumming and chemical degumming have been researched and practiced for a long time, under normal production efficiency, the final degumming rate of ramie is not high. If you want to increase the degumming rate, you have to repeat the degumming, but this will seriously affect the production. Efficiency and the quality of cellulose in ramie, the gain outweighs the gain

Embodiment 1

[0043] Below in conjunction with specific embodiment the degumming device of ramie of the present invention is further described, as attached figure 1 - attached Figure 8 Shown, the degumming device of the ramie in the present embodiment comprises the box body 10 of upper end opening of many pieces, is located at the guide rail above box body 10, and a plurality of grasping devices 20 that is located at box body 10 tops; The body 10 is evenly distributed along the transport direction of the guide rail; the guide rail is used to transport the grabbing device 20; the inside of the box body 10 is provided with a spraying device, a suspension device and a plurality of suspension rods 40; the suspension device is used to support the suspension rod 40; the grabbing device 20 is used for grabbing suspension bar 40; Suspension bar 40 is used for hanging ramie strip. Specifically, hang the ramie strips on the suspension rod 40, and use the grabbing device 20 to automatically grab the...

Embodiment 2

[0051] Use the degumming device in embodiment 1 to carry out degumming to ramie strip. The main operation steps are:

[0052] (1) pretreatment, stripping fresh ramie to obtain ramie strips with a large amount of fibers therein; using an extrusion device to fully compress the ramie strips, and hanging the ramie strips evenly on the suspension rod; using multiple grabbing devices At the same time, grab the suspension rod, wherein the liquids sprayed by the spray devices in the multiple boxes along the transport direction of the guide rail are biological degumming liquid, flushing liquid, chemical degumming liquid and flushing liquid in sequence, and repeat the arrangement in sequence;

[0053] (2) Biological degumming, the grabbing device grabs the suspension rod on which the ramie strips are suspended, and places it in the suspension device in the box, so that the ramie strips are fully washed by the biological degumming liquid in the box, wherein the biological degumming The ...

Embodiment 3

[0060] Use the degumming device among the embodiment 1 and the degumming method among the embodiment 2 to process 100kg through the ramie after stripping the hemp.

Abstract

The invention provides a ramie degumming device. The ramie degumming device comprises a plurality of box bodies with openings in the upper ends, guide rails arranged above the box bodies, and a plurality of grabbing devices arranged above the box bodies; the multiple box bodies are evenly distributed in the conveying direction of the guide rails; the guide rails are used for conveying the grabbing devices; a spraying device, a suspension device and a plurality of suspension rods are arranged in each box body; the suspension devices are used for supporting suspension rods; the grabbing devices are used for grabbing the suspension rods; and the suspension rods are used for suspending ramie strips. The ramie degumming device can efficiently and automatically complete degumming operation. The invention further provides a degumming method used in cooperation with the degumming device. By alternately using biological degumming and chemical degumming, degumming can be more efficient.

Description

technical field [0001] The invention relates to the technical field of ramie degumming, in particular to a ramie degumming device and a degumming method. Background technique [0002] Ramie fiber is composed of cellulose, hemicellulose, lignin and pectin, and its cellulose accounts for as high as 65-75%, which is the hemp fiber with the highest cellulose content. Ramie fiber is light in weight, strong, wear-resistant, breathable, anti-mildew and antibacterial, moisture-wicking and quick-drying, etc. It can be widely used in high-grade fabrics, clothing, shoes and hats, bedding, home decoration, and medical packaging. And ramie, as a unique hemp fiber variety in my country, has a wide planting area and rich resources. Therefore, the development of functional textiles based on ramie fibers has important research value and broad application prospects. [0003] Degumming is a very important link in the production process of ramie. By degumming, the colloid in ramie can be remo...
