Description

Technical Field

[0001] The utility model relates to the technical field related to bamboo fiber softening, in particular to a bamboo fiber softening treatment device. Background Art

[0002] Softening treatment is an important process for bamboo fiber. The softening effect directly affects the quality of bamboo fiber, as well as production efficiency and production cost. At present, most softening projects on the market are carried out in open immersion tanks. Since they cannot be closed, the softening process cannot be carried out under high temperature and high pressure conditions, so the reaction process is very slow. In addition, a lot of softeners need to be added during the softening process. Because the softening time is very long, the softening reaction is not uniform. The patent document with patent application number CN202222066217.5 in my country discloses a bamboo chip softening device for producing bamboo fiber, including a softening mechanism, wherein the softening mechanism includes a spherical pressure-resistant autoclave, and a detachable sealing upper cover is installed on the top of the spherical pressure-resistant autoclave. The two ends of the outside of the spherical pressure-resistant autoclave are respectively fixedly connected with hollow shaft necks; one end of the outside of one of the hollow shaft necks is fixedly connected with an exhaust valve pipe, and the other end of the outside of the hollow shaft neck is fixedly connected with an intake valve pipe, and the intake valve pipe and the exhaust valve pipe are connected with the interior of the spherical pressure-resistant autoclave through the hollow shaft necks; the device realizes pressurization by introducing gas, which is more troublesome and requires the setting of additional structures. At the same time, the internal stirring effect is poor during the softening process, and the bamboo fibers cannot be fully contacted with the softener. In addition, due to the spherical structure, it is more inconvenient to export the bamboo fibers.

[0003] Therefore, a novel device is proposed to solve the above-mentioned problems. Utility Model Content
