  • the present invention relates to a defoaming device for a high-viscosity spinning solution, and more particularly to a high-viscosity pure chitosan spinning solution defoaming device.
  • Pure chitosan fibers refer to fibers made from extracts from shrimp and crab shells, which have many special advantages over conventional terrestrial natural fibers and synthetic fibers. The first is that it does not rely on oil, nor does it compete with food for land, and opens up a third source of chemical fiber. Second, waste utilization is in line with the sustainable development trend of green and environmental protection. Further, the pure chitosan fiber has broad-spectrum bacteriostasis, mildew resistance, excellent biocompatibility and non-immunogenicity, and also has the functions of adsorption chelation, hemostasis, and scar reduction. Based on its function, it can be widely used in aerospace, medical and health, military civil textiles, filtration protection and other fields. It has great market potential and plays a positive role in promoting human health.

These gases are bound to the inside of the chitosan solution during the dissolution of chitosan, and cannot escape; at the same time, the chitosan spinning solution is dissolved, filtered, and transported. A large amount of air bubbles are also generated during the process until it is delivered to the defoaming kettle.

Description

一种高黏度纯壳聚糖纺丝液的脱泡装置 技术领域
[0001] 本发明涉及一种高黏度纺丝液的脱泡装置,尤其涉及一种高黏度纯壳聚糖纺丝 液脱泡装置。
背景技术
[0002] 纯壳聚糖纤维是指利用虾蟹壳中的提取物制成的纤维, 与传统的陆地天然纤维 与合成纤维相比具有许多特殊优点。 首先是既不依赖石油, 又不与粮食争夺土 地, 开辟了化学纤维的第三原料来源; 二是废物利用, 符合绿色、 环保的可持 续发展趋势。 进一步讲, 纯壳聚糖纤维具有广谱抑菌性、 防霉性、 优异的生物 相容性和无免疫原性, 还具有吸附螯合, 止血促愈、 减少疤痕的作用。 基于其 功能作用, 可广泛应用于航天、 医疗卫生、 军用民用纺织品、 过滤防护等领域 , 市场潜力巨大, 同时对人类的健康事业的起到积极地推动作用。
[0003] 脱乙酰度和黏度是壳聚糖的两个重要质量指标。 众所周知, 壳聚糖分子量越大 , 其黏度越大, 黏度与分子量的关系 Mark-Houwink表明, SP : [ ] = k M °,
( : 黏度, mpa · s, K: 常数, Μ: 相对分子质量, α: 是一个与分子量有关 的数值) 由此就可以看出纯壳聚糖纺丝液的黏度越高, 其分子量越大, 所纺制 的纯壳聚糖纤维的干断裂强度越高, 断裂伸长率越大, 可纺性越好。 因此, 只 有髙黏度的纯壳聚糖纺丝液才更符合高性能纯壳聚糖纤维的纺丝要求。 现在纺 制出高品质的纯壳聚糖纤维所需的纺丝液的黏度以大于 450000mpa * s为宜, 该 黏度的纺丝液是通常黏胶纺丝液黏度的近十倍, 采用常规工艺脱泡, 生产效率 极低, 无法实现工业化生产。
[0004] 片状壳聚糖本身在脱钙、 脱蛋白质后, 其组织中会产生大量的间隙, 这些间隙 会有空气充盈; 另外, 片状壳聚糖原料是 2片或多片的叠合而成, 其间隙间也存 有大量气体, 这些气体在壳聚糖溶解过程中, 粘结在壳聚糖溶液内部, 无法逸 出; 同时, 壳聚糖纺丝液在搅拌溶解、 过滤、 输送的过程中也会产生大量气泡 , 直至输送到脱泡釜内。 [0005] 湿法纺丝时, 纺丝液必须无气泡从喷丝板喷出进入凝固浴, 若纺丝液带有气泡 喷丝至凝固浴, 气泡逸出会导致断丝。 因此纺丝前必须进行脱泡处理。 由于纯 壳聚糖纺丝液的黏度大于 450000mpa · s, 是黏胶纤维纺丝液黏度的近十倍, 按 现有的常规脱泡方式生产效率极低, 难以实现工业化生产。
技术问题
[0006] 本发明所要解决的技术问题是克服现有技术的不足, 提供一种脱泡效率高、 脱 泡效果好的脱泡装置, 所述脱泡装置可一次性将气泡脱离干净, 且适用纺丝液 的黏度范围广。
问题的解决方案
技术解决方案
[0007] 本发明所采用的技术方案是 :
[0008] 一种高黏度纯壳聚糖纺丝液脱泡装置, 包括反应釜 1、 搅拌装置 2, 所述反应釜 1上部设有进料口 3, 底部中心位置设有出料口 4, 其特征在于: 所述反应釜 1上 部还设有真空口 5; 所述反应釜 1中心位置固定设有内筒体 9, 所述内筒体 9的上 端部筒体口封闭, 下端部筒体口开放; 内筒体 9上半部的外周上固定设有伞状散 流板 10, 所述伞状散流板 10的外边缘与反应釜 1的内壁之间有间隙; 所述内筒体 9在伞状散流板 10上面部分的筒体壁上布满出液小孔 11 ; 所述搅拌装置 2包括带 有螺旋浆 14的搅拌轴 12和搅拌动力装置 13, 所述搅拌轴 12的上端安装在搅拌动 力装置 13上; 搅拌轴 12穿过机械密封装置 16, 伸入反应釜 1内, 下端固定在带座 轴承 6上; 所述搅拌轴 12与内筒体 9的轴心线重合, 所述内筒体 9的内壁与螺旋浆 14之间有间隙。
[0009] 所述反应釜 1内上方固定设有环状进料管道 7, 所述环状进料管道 7与进料口 3连 通, 所述环状进料管道 7水平中心面以下部分布满出料小孔 8。
[0010] 所述伞状散流板 10与内筒体 9的轴线夹角 a = 65 ° 〜 80 ° 。
[0011] 所述内筒体 9的上端部筒体口用布满出液小孔 11的圆板封闭。
[0012] 所述搅拌轴 12与所述出料口 4在一条直线上。
[0013] 所述反应釜 1 的下部设有取样孔 18。
[0014] 所述环状进料管道 7是通过固定在反应釜 1内壁伞状散流板 10上方的托 杆 20而固定, 所述反应釜 1的内筒体 9是通过上、 下支撑杆 22固定在反应釜 1的中 心位置。

发明的有益效果
有益效果
[0017] 本发明的有益效果是 :
[0018] 1、 从本发明的结构上看:
[0019] a、 由于釜体内上方设有环状进料管道, 所述环状进料管道与进料口连通且 底部设有多个出料小孔, 带有压力的高黏度纯壳聚糖纺丝液通过进料口进入环 状进料管道再由出料小孔挤出时, 由于出料小孔直径仅有 0. 5mm-5mm, 且脱泡釜 内压力小于 3000pa, 纺丝液在重力的作用下自由下落至伞状散流板上, 纺丝液 内的气泡从出料小孔分离时受到剪切, 纺丝液界面层发生变化, 气泡快速脱出 , 完成高压分离剪切的第一次脱泡过程。
[0020] b、 实现第一次脱泡的纯壳聚糖纺丝液均匀的滴流在伞状散流板上, 由于重力 的作用和伞状散流板的倾斜角度, 纺丝液从伞状散流板内边缘向伞状散流板外 边缘流动, 形成的纺丝液薄膜, 增大了脱泡面积, 在脱泡釜内压力小于 3000pa 条件下, 部分气泡自由逸出; 纺丝液流到伞状散流板外边缘时, 纺丝液在重力 的作用下自由下流至反应釜底部, 下流时, 伞状散流板外边缘对纺丝液产生剪 切作用, 纺丝液界面层发生变化, 气泡快速脱出, 完成刮膜剪切的第二次脱泡 过程。
[0021] c、 本发明所述的脱泡釜具有内筒体和带有螺旋浆的搅拌轴, 以及所述伞状散 流板上部的内筒体壁和上端部密封盖上布满出液小孔的特殊结构的, 实现第二 次脱泡过程的纯壳聚糖纺丝液经过螺旋浆搅拌, 从釜体底部提升至内筒体的上 部, 那么, 这些纯壳聚糖纺丝液只能通过出液小孔挤出, 实现 (a) 过程的脱泡 效果; 当纺丝液滴流到伞状散流板上面至釜体底部的过程中, 实现 (b ) 过程的 脱泡效果, 完成这一搅拌提升装置的一个流程就实现了 (a) 和 (b ) 两个脱泡 过程的脱泡效果。 特别是避免了常规脱泡法在脱泡釜底部的纺丝液难以脱泡的 弊病。 此装置连续运行, 实现高效率、 高质量脱泡。
[0022] 2、 从脱泡的实际效果来看: 在同容积、 同截面积的反应釜内用本发明, 6吨黏 度为 500000 mpa · s的纯壳聚糖纺丝液 8小时内能完全脱泡, 用常规真空脱泡技 术, 6吨黏度为 500000 mpa · s的纯壳聚糖纺丝液 40—55小时能完全脱泡, 可见 , 本发明能提高脱泡效率 5-7倍。

实施该发明的最佳实施例
本发明的最佳实施方式
[0027] 为了把本专利说明清楚, 现结合附图 1、 图 2, 具体说明如下。
[0028] 一种高黏度纯壳聚糖纺丝液脱泡装置, 包括反应釜 1、 搅拌装置 2, 所述的反应 釜 1由上封头、 下封头和筒体焊接组成, 所述上、 下封头都为椭圆形, 可根据承 压的大小及承压的压差来决定上封头、 下封头和筒体不锈钢材料的厚度和材质
[0029] 所述反应釜 1上部设有进料口 3, 所述的进料口 3的位置设置在反应釜 1的上部 的侧面, 所述的进料口 3设置在反应釜 1上半部侧面并和反应釜 1内的环状进料 管道 7在同一平面内时最好。
[0030] 反应釜 1底部设有出料口 4, 所述的出料口 4最好在反应釜 1底部的中心位置, 便于脱完泡的纺丝液排出; 底部还可以设有取样口 18, 便于了解纺丝液脱泡的 情况。
[0031] 所述反应釜 1上部设有真空口 5, 最好在反应釜 1的上封头上, 便于反应釜 1内气 体逸出。
[0032] 反应釜 1的上部还可以设有破坏真空进气口 15, 使得脱泡完成后, 反应釜 1内变 成常压, 便于开启反应釜 1, 也便于输出纺丝液。
[0033] 所述反应釜 1内还可以设限位器 19, 便于了解反应釜 1内纺丝液的容量情况。
[0034] 所述反应釜 1上部设有观察窗 21、 安全阀 28、 电接点压力表 29、 真空表 17、 人 孔 23、 压缩空气放气口 24, 视镜灯 26, 视镜 27。
[0035] 所述环状进料管道 7是通过固定在反应釜 1内壁伞状散流板 10上方 150mm处的托 杆 20而固定, 所述环状进料管道 7与进料口 3连通且水平中心面以下部分的管壁 上均匀布满直径为 0. 5mm-5mm出料小孔 8。
[0036] 内筒体 9固定在反应釜 1的中心位置, 所述的固定是指通过上、 下支撑杆 22, 把 内筒体 9固定在反应釜 1内。 所述的内筒体 9的上端部筒体口封闭仅仅是相对下端 部筒体口开放而言, 实际上, 内筒体 9的上端部筒体口用布满出液小孔 11的圆板 封闭, 其目的是既阻止螺旋浆 14提升上来的纺丝液从上端部筒体口直接流出, 又能让纺丝液从上端部筒体口圆板上的出液小孔 11挤出, 液体下流, 气泡逸出 , 起到脱泡作用; 另外, 由于纺丝液的快速提升及内筒体上端部筒体口的阻力 , 对上部筒体的侧壁产生一个较大的压力, 纺丝液也会从上部筒体侧壁出液小 孔 11挤出, 液体下流, 气泡逸出, 从而达到脱泡的效果。
[0037]
所述伞状散流板 10固定在内筒体 9上半部的外周上, 应保证伞状散流板 10下边缘 在有效容积液面之上, 所述伞状散流板 10的顶部最好固定在距内筒体 9上端部筒 体口 300mm处, 这样, 内筒体 9就被伞状散流板 10分成上部与下部两部分; 所述 环状散流板 10 与内筒体 9的轴线夹角 a = 65 ° 〜 80 ° ; 所述环状散流板 10的 外缘周与反应釜 1的釜内壁之间有 100mm-200mm的间隙; 所述伞状散流板 10经过 抛光处理。
[0038] 所述搅拌动力装置 13包括电机、 减速机、 动力支架 25, 动力支架 25安装在反 应釜 1的顶部外壁上, 在动力支架 25上安装着减速机和电机; 搅拌轴 12的上端安 装在搅拌动力装置 13上, 具体是搅拌轴 12和减速机的输出轴联动; 所述搅拌轴 1 2从上端向下穿过动力支架 25内设有的带座轴承, 穿过用来密封反应釜 1与述搅 拌轴 12之间装配间隙的机械密封装置 16, 进入溶解釜 1中, 下端固定在底部带座 轴承 6上 , 通过上下两端固定后, 搅拌轴 12运行更稳定。
[0039] 所述带座轴承 6固定在反应釜 1的内壁底部轴心位置上;
[0040] 所述搅拌轴 12与内筒体 9的轴心线重合并与所述出料口 4在一条直线上;
[0041] 所述螺旋浆 14与内筒体 9的内筒壁之间有 3mm-5mm的间隙。
工业实用性
[0042] 众所周知, 纯壳聚糖纺丝液的黏度越高, 由其制备成的壳聚糖纤维干断裂强度 越高, 断裂伸长率越高, 可纺性越好。 在常温下, 纯壳聚糖纺丝液会随着时间 的延长发生降解, 黏度降低, 这就导致制备成的纯壳聚糖纤维质量下降。
[0043] 本发明大大减少了纺丝液的降解, 实现了纯壳聚糖纺丝液高效率、 高质量脱泡 , 保证了高质量纯壳聚糖纤维的工业化生产。
[0044] 本发明脱泡效率高、 脱泡效果好、 避免纺丝出现断丝的高黏度纺丝液脱泡装置 , 所述该装置可一次性将气泡脱离干净, 且适用料液的黏度范围广。
