技术领域
本申请涉及甘蔗除杂技术领域，例如涉及一种除杂系统及除杂方法。
背景技术
相关技术中，甘蔗生产早已经实现全程的机械化，部门生产环节机械化正向自动化和智能化方向发展。随着我国劳动力的短缺和甘蔗采集成本的提高，部分糖厂也逐步开始了使用甘蔗机械化收割联合人工劳动力一起收获甘蔗，但不管是人工劳动收获还是机械化收获，对甘蔗进行杂质和蔗叶去除的含杂率高，尤其是机械化的收割含杂率高达15％-20％之多，人力收割的收割含杂率也多达7％。
甘蔗夹杂物主要包括随甘蔗带来的蔗叶、蔗梢、须根和泥土等。夹杂物可分为纤维类和泥土类。夹杂物不含糖分，或者是含不可回收的糖分使淀粉和还原糖含量增多，影响甘蔗制糖生产线的产糖率；另外夹杂物在压榨和清净过程中还会从蔗茎及混合汁中吸取蔗糖分，减少糖分的回收，过多的夹杂物进入到制糖生产，会对制糖生产的设备、工艺及回收等产生很大影响。

本实施例中，第一振动分筛机22与第二振动分筛机23的结构相同。以第一振动分筛机22为例，如图3和图4所示，第一振动分筛机22包括振动网格筛221、安装振动网格筛221的连接槽钢222、驱动连接于连接槽钢222两端的主动曲轴组223及从动曲轴组224，所述主动曲轴组223驱动连接有驱动减速电机226。实际应用中，通过驱动减速电机226驱动，主动曲轴组223带动从动曲轴组224，使得连接槽钢222振动，通过将振动网格筛221作为甘蔗的支撑面，从而使得甘蔗带有的泥沙和甘蔗叶等杂物从网格中脱落；通过采用电机带动曲轴组的方式，从而使得放置于振动网格筛221的原料蔗以弧形的运动轨迹运动，即原料蔗从第一振动分筛机22弧形抛落入第二振动分筛机23。
本实施例中，所述第一振动分筛机22还设有调节升降油泵225，所述调节升降油泵225连接于从动曲轴组224，实际应用中可通过调节升降油泵225调节从动曲轴组224的高度，使得振动网格筛221处于最佳振动除杂位置。
本实施例还提出了一种能够应用于上述除杂系统中的除杂方法，以去除甘蔗中的泥沙和甘蔗叶等杂质。如图6所示，所述除杂方法包括如下步骤：
S10：在分切预处理工位上，进行分切预处理。
其中，所述分切预处理包括：通过链板机11将原料蔗向上运输至甘蔗分切机13；驱动所述甘蔗分切机13将原料蔗切割成段并送至所述均料装置14；及通 过所述均料装置14将原料蔗分配于分料槽15的多个分料通道151。
S20：在除杂分选工位上，通过除杂分选装置2进行除杂分选处理。
其中，所述除杂分选处理包括：将S10处理后的原料蔗经过除杂分选装置2进行呈阶梯式的多级除杂，使得掺杂在原料蔗内的泥沙杂质脱落。
当原料蔗由除杂分选装置2中的上一级除杂设备下落至下一级除杂设备时，设于上一级除杂设备出料口的热风鼓风机送出热风吹原料蔗，使原料蔗和蔗叶在气流作用下因密度大小不一样分离，实现分选泥沙杂质与蔗叶。
S30：在废料回收工位上，进行循环回收处理。
其中，所述循环回收处理包括：通过皮带机构4将S20分离出的蔗叶依次送入蔗叶破碎机33和蔗渣锅炉34；及将废弃的蔗叶燃烧后产生的热能作为第一热风鼓风机24、第二热风鼓风机25及第三热风鼓风机26的发电动力。
本实施例中的所有技术特征均可根据实际需要而进行自由组合。
