Problems solved by technology

[0002] Rice and wheat are the main food crops in my country, and the output of rice straw and wheat straw is also quite high. The current comprehensive utilization rate is less than 10%, and more than 90% of rice straw and wheat straw are burned as waste. The burning process pollutes the environment
On the other hand, my country's forest resources are scarce, and raw material wood is in short supply. For example, the supply of fiber raw materials urgently needed by the paper industry is insufficient.

Embodiment 1

[0037] Example 1. The method of extracting rice or wheat straw fiber is an example, and is illustrated in conjunction with accompanying drawing 1:

[0038] Remove the dust and sundries from the raw material stalks and segment them; the extraction steps are:

[0039] 1) rough extraction of stalks, the threshed crop stalks are shredded into small pieces on the spot with the rough extraction device 10, and

[0040] Rough extraction to get rough straw; return impurities, dust and soil directly to the field;

[0041] 2) steam treatment, heating and moistening the crude straw through a steam treatment device for 6 minutes;

[0042] Stripping and combing are carried out in time to make the fiber in the straw rich in toughness and elasticity, and to make the attached tissue in the straw swell and soft and easy to separate;

[0043] 3) Straw fine extraction, the steam-treated crude straw is further stripped and combed with a fine extraction device to remove the attachment tissue in ...

Embodiment 2

[0047] Embodiment 2, equipment.

[0048] The equipment used is shown in FIG. 1 , including a rough extraction device 10 , a steam treatment device 20 , a fine extraction device 30 and a cleaning device 40 .

[0049] The stalk rough extracting device 10 comprises 1 pair of coarse feed rollers 12, the thick steel wire wheel 13 and the coarse screen wheel 17 that successively connect, thick steel wire wheel cover 14 and coarse screen wheel cover 19; On the coarse steel wire wheel 13 There is a wire tip 16 and a tip 15 on the coarse wire wheel cover 14; a pair of coarse feed rollers 12 are located at the feed end of the coarse wire wheel 13. Referring to FIG. 2, the thick wire wheel 13 is hollow and has a wire tip 16 on its outer surface. Referring to Fig. 3, the coarse screen wheel 17 is hollow, and its outer surface is covered with a wire mesh 17B of sieve holes, and there are 2 support gears 17A below the coarse screen wheel 17, which are driven by the support gear 17A. There...

Description

technical field [0001] The invention relates to a technology for extracting plant fibers, in particular to a method and equipment for extracting straw fibers. Background technique [0002] Rice and wheat are the main food crops in my country, and the output of rice straw and wheat straw is quite high. The current comprehensive utilization rate is less than 10%, and more than 90% of rice straw and wheat straw are burned as waste. The burning process pollutes the environment. On the other hand, my country's forest resources are scarce, and raw material wood is in short supply. For example, the supply of fiber raw materials urgently needed by the paper industry is insufficient. The applicant of this patent once provided a method and equipment for extracting straw fibers in Chinese patent application 200610076784.1 A method and equipment for extracting straw fibers. The extraction device is used to shred and peel it to extract fibers, and finally filter and separate to make str...
