Description
技术领域
本发明涉及一种用于医药生产的原料混合装置,属于生物医药技术领域。
背景技术
医药行业是我国国民经济的重要组成部分,是传统产业和现代产业相结合,一、二、三产业为一体的产业。其主要门类包括:化学原料药及制剂、中药材、中药饮片、中成药、抗生素、生物制品、生化药品、放射性药品、医疗器械、卫生材料、制药机械、药用包装材料及医药商业。医药行业对于保护和增进人民健康、提高生活质量,具有十分重要的作用。
随着医药领域新药化学结构的日趋复杂,常常会需要特殊的有机药物中间体,再加上环保要求日趋严格,很多公司感到依靠自己的力量和资源难以完成所需的全部原料药、中间体的开发和生产。因此,为了制备得到所需的特殊中间体,对医药中间体的研究开发机构和生产企业提出了新的要求,而在生产环节,也对传统的医药中间体生产设备提出了新的要求。例如对于化工医药领域的原料搅拌装置来说,传统装置在原料混合阶段,例如对于大多数粘稠度较大的原料来说,混合过程中搅拌桨剪切阻力大,混合效率较低,生产效率难以提升。
发明内容
为解决现有技术中存在的问题,本发明提供了一种用于医药生产的原料混合装置,该混合装置具有搅拌效率高、清洁性好的优点。具体技术方案如下:
一种用于医药生产的原料混合装置,包括壳体,所述壳体上方开设有进料口,所述壳体下方开设有出料口,所述壳体内壁设置的固定边齿和横向增强杆,所述固定边齿的数目为偶数个、且对称设置于壳体内壁两侧,所述出料口下方设置有驱动电机,所述驱动电机上方转轴连接有贯穿横向增强杆的搅拌轴,所述搅拌轴与横向增强杆之间设置有轴套,所述搅拌轴侧面对称设置有条形转动齿,所述壳体上设置有伸入固定边齿和横向增强杆内的热交换管路,所述热交换管路包括流体进口、内部管道和流体出口,所述固定边齿下方设置有形状记忆合金。
作为上述技术方案的改进,所述形状记忆合金包括多组间隔设置的第一记忆金属和第二记忆金属。
作为上述技术方案的改进,所述固定边齿的数目为六个、且壳体内壁每一侧各有三个。
作为上述技术方案的改进,所述热交换管路在固定边齿和横向增强杆内呈“M”形折弯分布。
作为上述技术方案的改进,所述搅拌轴上位于横向增强杆和出料口之间的位置设置有“V”形搅拌桨。
作为上述技术方案的改进,所述条形转动齿和搅拌桨的截面呈三角形。
上述技术方案具有以下两个方面的优点:(1)热交换管路采用贯穿固定边齿和横向增强杆的设计,能够在原料混合过程中提高壳体内部的温度,提高混合效率;
(2)通过热交换管路的加热,使得位于固定边齿下方的形状记忆合金发生结构变化,避免原料粘附在该区域,提高了壳体内部的清洁性,有益效果显著。
附图说明
图1为本发明一种用于医药生产的原料混合装置的主视图;
图2为本发明一种用于医药生产的原料混合装置的仰视图(隐藏了驱动电机和壳体下方靠近出料口的部分区域)。
具体实施方式
如图1、图2所示,本发明提供了一种用于医药生产的原料混合装置,包括壳体10,壳体10上方开设有进料口11,壳体10下方开设有出料口12,壳体10内壁设置的固定边齿13和横向增强杆14,固定边齿13的数目为偶数个、且对称设置于壳体10内壁两侧,出料口12下方设置有驱动电机20,驱动电机20上方转轴连接有贯穿横向增强杆14的搅拌轴21,搅拌轴21与横向增强杆14之间设置有轴套15,搅拌轴21侧面对称设置有条形转动齿22,壳体10上设置有伸入固定边齿13和横向增强杆14内的热交换管路,热交换管路包括流体进口30、内部管道31和流体出口32,所述固定边齿13下方设置有形状记忆合金。
上述方案中,待混合原料首先通过进料口11进入到壳体10内部,然后驱动电机20带动搅拌轴21转动,进而带动条形转动齿22转动,由于壳体10内壁上设置有固定边齿13,当条形转动齿22转动时,其与固定边齿13进行交叉剪切,进而实现对原料的高效混合,混合完成后,开启出料口12,即可将混合后的原料排出。
上述方案中,横向增强杆14的作用有两个:第一,是对壳体10两侧进行支撑;第二,是对搅拌轴21进行约束。热交换管路贯穿固定边齿13和横向增强杆14,能够在原料混合过程中提高壳体10内部的温度,进而提高混合效率。
上述方案中,形状记忆合金包括多组间隔设置的第一记忆金属40和第二记忆金属41,其中形状记忆合金是利用在特定温度下合金会发生收缩或膨胀,从而使自身形态发生变化,之所以在方案中设计有形状记忆合金,是因为在大多数较为粘稠的原料混合过程中,位于固定边齿13下方的位置通常属于原料残留的死角,该部分受限于固定边齿13自身的固定状态,而难以清理,为此,通过热交换管路的加热,使得位于固定边齿13下方的形状记忆合金发生结构变化,避免原料粘附在该区域。其中,形状记忆合金可以是多组间隔设置的第一记忆金属40和第二记忆金属41,其中第一记忆金属40和第二记忆金属41可以从Au-Cd、Ag-Cd、Cu-Zn、Cu-Zn-Al、Cu-Zn-Sn、Cu-Zn-Si、Cu-Sn、Cu-Zn-Ga、In-Ti、Au-Cu-Zn、NiAl、Fe-Pt、Ti-Ni、Ti-Ni-Pd、Ti-Nb、U-Nb和Fe-Mn-Si中进行选取,需要注意的是,第一记忆金属40和第二记忆金属41应当选取热膨胀系数差异较大的两组。
更进一步的,固定边齿13的数目为六个、且壳体10内壁每一侧各有三个;为了提高热交换管路的换热效率,热交换管路在固定边齿13和横向增强杆14内呈“M”形折弯分布。
进一步的,搅拌轴21上位于横向增强杆14和出料口12之间的位置设置有“V”形搅拌桨23,条形转动齿22和搅拌桨23的截面呈三角形。该优选方案中,之所以采用三角形界面的条形转动齿22和搅拌桨23,是为了提高原料混合时的剪切效率。
