Embodiment 1

[0033] attached figure 1 and 2 Provided a specific embodiment of the present invention, as can be seen by accompanying drawing, the present invention relates to a kind of three-stage long bamboo fiber drying and dust separation device, comprises a plurality of drying separation cylinders 2,5 similar in internal structure and size and 7, hot air 13 and racks 4, 8 and 9; and three drying and separating cylinders are arranged in series to form a multi-stage drying and separating cylinder, and the outlet of the upper stage drying and separating cylinder is connected to the next stage of drying The inlet 6 of the separation cylinder; a plurality of dry separation cylinders are placed on the frame 4, 8 and 9, and the hot blast stove 13 is placed next to the dry separation cylinder, and the hot blast from the outlet of the hot blast stove is separated from the last stage of the dry separation cylinder. The cylinder is connected, and the hot air from the outlet of the hot blast stove...

Embodiment 2

[0040] Embodiment two is basically the same as embodiment one, except that the number of stages adopted is four, but the shape and structure of the cylindrical rotor drying and separation device of each stage are the same, but the rotating speed is different; The rotor rotation speed of the separation device is controlled at 50-70 rpm, the rotor rotation speed of the second-stage drum rotor drying and separation device is controlled at 70-90 rpm, and the rotor rotation speed of the third-stage drum rotor drying and separation device is controlled at 90 -120 rpm, the rotor rotation speed of the four-stage drum rotor drying and separation device is controlled at 120-150 rpm. The working principle of the second embodiment is the same as that of the first embodiment.

[0041] As can be seen from the above examples, the present invention relates to a method for drying and dust separation of long bamboo fibers, using a multi-stage long bamboo fiber drying and dust separation method ...

Abstract

The invention provides a method for drying long bamboo fiber and separating dust and a drying and dust separating device. The multistage method is used for drying the long bamboo fiber and separating dust. The long bamboo fiber is arranged in two or more drum type rotor drying and separating device bodies to be dried and separated from dust, wherein the rotating speed of each level of drum type rotor drying and separating device bodies is higher than that of the former level of drum type rotor drying and separating device bodies, flowing of the long bamboo fiber in a drying device is accelerated by means of a progressive increase of the rotating speed, and the phenomenon that materials are blocked after the fiber accumulates is avoided.

Description

technical field [0001] The invention belongs to a material processing method and processing device, in particular to a drying and separation method and device for forming a wet mixture of long bamboo fibers and dust through mechanical fiber opening of bamboo after chemical or biological fermentation treatment; mainly used for Production of long bamboo fibers. Background technique [0002] Long bamboo fiber is a kind of green ecological environment-friendly fiber extracted from bamboo by high-tech means. Long bamboo fiber refers to the main organization of bamboo - vascular fiber, which is mainly used in the manufacture of bamboo fiber composite materials (such as automobile interior Decorative materials) and high-grade fabrics are the most promising natural fibers in the 21st century. Long bamboo fiber is made of bamboo, which is mechanically opened after chemical or biological fermentation to form a wet mixture of long bamboo fiber and dust; in the process of making long b...
