Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 , figure 2 Shown, the present invention comprises a feeding area 1, and feeding area 1 connects a mechanical kneading area 2, and mechanical kneading area 2 connects a beat impurity removal area 3, beats the impurity removal area 3 and connects a discharge area 4, and is arranged on The impurity removal devices 5 on the upper and lower parts of the above-mentioned regions.

[0019] The feeding zone 1 of the present invention includes a feeding platform 11, and the bast fibers sorted out in the early stage are spread out on the feeding platform 11 and sent into the mechanical kneading zone 2.

[0020] The mechanical kneading zone 2 of the present invention includes two rows of upper and lower grooved rollers 21, 22 arranged in pairs. The tops of the two ends of the upper grooved roller 21 are respectively provided with pressu...

Abstract

The invention relates to a mechanical degluing method and a device of phloem fiber. The method of the invention comprises the following steps: 1) spreading and flatly paving phloem fiber in bundles, manually or mechanically feeding the phloem fiber between two rows of upper rollers and lower rollers in arrangement in pairs; 2) driving the upper rollers and the lower rollers to do alternating movement in the positive direction and the reverse direction through a motor, in addition, ensuring that the movement time in the positive direction is longer than the movement time in the reverse direction, and repeatedly extruding, kneading and forwards conveying the phloem fiber; 3) carrying out manual or mechanical oscillation and impurity removal through flapping on colloidal particles and dust on the phloem fiber at the same time of conveying the processed phloem fiber in the second step by a conveying belt; and 4) carrying out manual and mechanical shaking for further impurity removal on the processed phloem fiber in the third step, and then, packing the phloem fiber into bundles. The invention has the advantages of reasonable structural design, ideal degluing effect, small degluing pollution and safe and reliable operation, and can be widely used in the degluing process of phloem fiber, leaf fiber and gramineae fiber raw materials and the like.

Description

technical field [0001] The invention relates to a degumming method and device, in particular to a bast fiber mechanical degumming method and device. Background technique [0002] At present, in the industrial degumming process of bast fiber, chemical degumming is mainly used. Because chemical degumming requires long-term scouring of raw hemp under high temperature, high pressure, and high-concentration caustic soda, there are disadvantages such as large energy consumption, large alkali consumption, long time consumption, and serious environmental pollution. With the increase of environmental protection requirements and the shortage of water resources, chemical degumming requires the use of high-concentration lye and the COD value of wastewater is increasingly restricting the development of the hemp spinning industry, and has become an urgent problem for the hemp spinning industry to solve . If degumming can be carried out in an appropriate physical and mechanical manner be...
