Description

Technical Field

[0001] The invention relates to the technical field of raw fiber degumming, and in particular to a supercritical carbon dioxide antibacterial fiber degumming reactor. Background Art

[0002] Supercritical carbon dioxide is a carbon dioxide fluid maintained above the critical temperature and critical pressure. When the temperature of carbon dioxide exceeds 31 degrees Celsius and the pressure exceeds 7.3 MPa, it will enter a supercritical state. Supercritical carbon dioxide has both gaseous properties, such as low viscosity and high diffusivity, and liquid properties, such as high density and strong solubility. Supercritical carbon dioxide is used in conjunction with a reactor and utilizes its high solubility, which makes it perform well in many textile industry applications. For example, the apocynum plant contains relatively rich natural fibers. After harvesting, apocynum ramie generally undergoes two main processing steps to become a spinnable fiber: peeling and degumming. The hemp skin obtained by peeling is not directly used for spinning. Because a large amount of non-cellulose substances will adhere to the hemp bark and surround the fibers, these impurities may mask the antibacterial properties of the fibers themselves, and therefore a degumming reactor is needed to degumming and antibacterial finishing the ramie bast fibers; currently, when degumming the hemp bark bast fibers, a stirring rod provided in the degumming reactor is required to stir the solution in the reactor with the hemp bark bast fibers to speed up the reaction, and most of the hemp bark bast fibers are piled up in the reactor for stacking and fermentation, so that the hemp bark bast fibers will contact each other in the reactor and cause cross-entanglement, resulting in uneven degumming at the cross-entangled parts of the hemp bark bast fibers during degumming, increasing the time required for degumming the hemp bark bast fibers, affecting the structural stability of the hemp bark bast fibers, and increasing the loss of the hemp bark bast fibers by the degumming reactor.

At this time, the flowing liquid contacts and collides with the blocking frame 61, so that the flow of the liquid near the blocking frame 61 changes, so that the liquid flows disorderly in the kettle body 1, and the reaction speed is accelerated, which can ensure the uniformity and stability of the degumming reaction; and the servo motor 37 is used to drive the adjusting column 31 to rotate in the opposite direction, and the rotation of the adjusting column 31 drives the first threaded column 32 to rotate synchronously, so that the moving ring 33 slides upward along the outside of the first threaded column 32, which is used to drive multiple contact frames 24 to shrink synchronously. At the same time, the servo motor 37 rotates to drive the first gear 71 to rotate, and the first gear 71 rotates to engage with the second gear 72 to drive the third gear 74 to rotate, and the second gear 72 rotates around the outside of the stabilizing seat 73, so that the third gear The rotation of 74 drives the second threaded rod 76 to rotate in the sealing cover 28 and the cylinder sleeve 75 in a centering manner. As the second threaded rod 76 rotates, it is screwed and transmitted with the inner screw ring 66, and the inner screw ring 66 slides up and down along the outside of the first threaded column 32, and the inner screw ring 66 moves downward to drive the sliding sleeve 67 to move synchronously, and the movement of the sliding sleeve 67 drives multiple second hinged seats 65 to move synchronously, and through the movement of multiple second hinged seats 65, multiple fourth swing arms 64 are pushed and the blocking frame 61 is lifted upward. As the blocking frame 61 moves upward, the third swing arm 63 is pushed to move synchronously, so that the third swing arm 63 rotates around the first hinged seat 62, so that the stretching operation is completed between the multiple blocking frames 61, thereby maintaining the synchronous adjustment of the contact frame 24 and the blocking frame 61, and then the blocking frame 61 can replace the contact frame 24 in time to support and tighten the fiber raw material 14, and then the contact part between the contact frame 24 and the fiber raw material 14 is replaced, and the liquid in the kettle body 1 can be fully in contact with the fiber raw material 14, thereby improving production efficiency and output.

[0057] The above only describes certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, a person skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
