AI Technical Summary
[0003]在大豆蛋白粉生产加工领域,混合机是关键设备之一,其搅拌桨结构直接影响大豆蛋白粉混合的均匀度和生产效率,现有的申请号为CN202321321224.3的一种搅拌桨,此案例通过在桨叶表面固定设置耐磨砖,作为桨叶直接对物料进行搅拌,耐磨砖耐磨性、抗氧化性相对较强,避免了搅拌桨内部的主体部分裸露直接与物料接触,导致容易被氧化和腐蚀,然而,该案例在使用过程中采用耐磨砖作为搅拌桨进行搅拌的方式,会增加转轴的负载,从而导致搅拌桨在长时间高速运转过程中与转轴之间的连接出现松动,导致搅拌不稳定,影响混合效果,同时由于耐磨砖属于脆性材料,抗冲击性能差,在搅拌过程中,若遇到硬质颗粒或设备启停时的瞬时冲击,搅拌桨边缘或薄弱部位会发生崩裂和掉块情况
本实用新型通过第一螺纹槽使固定盖能紧密安装,配合内部上下对称的密封环,可有效防止大豆蛋白粉等进入安装筒内,通过两组轴承能够保障转轴稳定且顺畅转动,搅拌桨本体采用316L不锈钢,耐腐蚀性强,能够延长该结构的使用寿命,四组交叉设计的搅拌叶,能增大与大豆蛋白粉接触面积,使混合更均匀高效,安装筒通过第二螺纹槽与混合机主体相连,使该结构的安装便捷且稳固。
