Description

Technical Field

[0001] The utility model relates to the technical field of bamboo fiber production, in particular to a high-temperature reaction kettle for bamboo fiber production. Background Art

[0002] Bamboo fiber is cellulose fiber extracted from naturally grown bamboo. It is the fifth largest natural fiber after cotton, linen, wool and silk. Bamboo fiber has good air permeability, instant water absorption, strong wear resistance and good dyeing properties. It has natural antibacterial, antibacterial, mite removal, deodorization and UV resistance functions. The main components are cellulose, hemicellulose and lignin. The three are all high polysaccharides, and the total amount accounts for more than 90% of the dry mass of the fiber. Bamboo fiber can be blended with vinylon to produce light clothing fabrics. Cotton, wool, linen, silk and chemical fibers can be blended for weaving or knitting to produce woven fabrics and knitted fabrics of various specifications.

[0003] In the production process of bamboo fiber, bamboo fiber and chemical reagents need to be placed in a reactor for mixing and stirring.

[0004] After searching, it is found that in a high-temperature reaction kettle for making bamboo fiber with patent publication number CN213674584U, it is proposed that "the utility model controls the lifting motor, stirring motor and heating electric tube by controlling the switch group, and facilitates the up and down movement of the kettle cover through the lifting unit, and can quickly open or close the internal space of the kettle body, and can make the kettle body and the kettle cover more tightly connected through the sealing rubber ring and the sealing groove";

[0005] However, the above scheme still has certain shortcomings in actual use. Since the bamboo fiber itself still contains a large amount of water, and the device does not pre-treat the water content of the bamboo fiber itself before putting the bamboo fiber into the reactor, the concentration of the chemical reagent will be diluted when the bamboo fiber containing a large amount of water is mixed with the chemical reagent, thereby greatly reducing the reaction effect of the chemical reagent on the bamboo fiber, thereby affecting the production quality of the bamboo fiber.
