Description

螺旋式发酵翻拌机 技术领域
本发明属于发酵设备领域， 应用于各种肥料、 饲料和食品等有机物料进行好氧发 酵工艺中， 具体涉及一种对发酵物料进行翻拌的同时， 实现对物料强制通风增氧作业 的装置。 背景技术
目前对肥料、 词料和食品等有机物料进行好氧发酵时， 经常需要采用槽式发酵方 式，而与之相配套，在发酵过程中则采用螺旋式翻拌机适时对发酵有机物料进行翻拌、 通风和增氧。 但现有的螺旋式翻拌机受其结构和工作原理的影响和制约， 物料只是在 原地上下翻动， 只能达到翻拌的目的。 由于翻拌过程中新鲜空气无法进入物料内部， 只有被翻到料堆表面的物料有机会接触到新鲜空气， 而内部的物料根本无法接触到新 鲜空气， 所以对发酵物料的通风降温和增氧效果很不理想。 由于参与发酵的好氧微生 物得不到充足的氧气供应， 以及发酵物料内部热量无法与外部空气进行充分交换， 其 内部由于高温形成的湿热水蒸汽得不到及时充分蒸发， 物料内部温度不能快速有效调 节， 使物料不能经常处于最佳发酵状态， 导致物料发酵周期过长， 降低了发酵车间的 周转率和利用率， 加大了企业对发酵车间设施和发酵设备的投资， 同时还增加了发酵 生产过程中的能耗， 影响企业的经济效益。
为了改进上述不足， 有的企业在此方面进行了技术创新， 在翻堆机上加装了强制 通风装置， gp : 通过设置在螺旋式翻拌机机架上的空心螺旋轴， 在空心螺旋轴上幵孔, 供气设备通过空气管道与空心螺旋轴连接， 在进行翻拌作业时， 空心螺旋轴在翻拌机 传动机构的驱动下转动， 对物料进行翻拌， 同时供气装置启动， 气流通过空气管道进 入空心螺旋轴， 穿过空心螺旋轴轴壁上的出气孔进入发酵物料中。 上述创新在理论上 是可行的， 但在实际生产应用中基本没有实际效果。 因为受螺旋轴轴径的限制， 为了 保证螺旋轴的机械强度，穿过螺旋轴的气孔孔径只能开得很小，大概在 10 15 mm之间， 因此供气设备通过此气孔供入空心螺旋轴的空气压力很小、 流量也很小， 根本就无法 渗透和穿透物料， 给发酵物料强制通风增氧的目的还是没有达到。 因此， 增加此装置 后翻拌机的效果几乎没有得到实质性的改善。
文献介绍中国专利申请号： 200620030783. 9 , 公丌一种螺旋式翻拌机通风装置， 公开（公告）号： 应用在各种肥料、 词料、 食品进行发酵的工艺中的一种对发酵物料进 行翻拌的同时实现对物料的强制通风作业的螺旋式翻拌机通风装置， 包括设在螺旋式 翻拌机机架上的空心螺旋轴， 在空心螺旋轴上开有孔， 供气设备通过空气管道与空心 螺旋轴连接， 具有对发酵物料强制通风， 改善物料的发酵条件， 增强发酵效果， 缩短 发酵周期的优点。
本专利申请人于 2008 年也现有翻拌机的技术进行了改进， 并申请了专利 （申请 号 200810073792. X) , 即在螺旋轴的两侧加装了通风管， 可使螺旋翻拌机在对发酵物 料进行翻拌的同时， 能够保证有与物料种类、 发酵时期和物料厚度相适应的压力和流 量的空气从物料层中穿过， 真正实现对物料的强制通风和增氧， 有效改善物料的发酵 条件， 显著提高发酵效果。 但在实际运用过程也还存在一些问题， 即在螺旋轴两侧加 装通风管后， 翻拌机在物料中行进时阻力增大， 使发酵物料的厚度较大时会出现翻拌 机无法正常前进， 发生倾覆现象， 因此一方面发酵物料的堆积厚度受到限制， 另一方 面翻拌机行进的平稳性和安全性受到影响。 发明内容
本发明的目的在于克服现有设备中存在的不足， 提供一种能根据发酵物料种类、 发酵时期及发酵物料厚度的不同， 都有与之相适应的压力和流量的空气穿透发酵物 料， 真正改善物料的发酵条件， 增强发酵效果， 大大缩短发酵周期的带强制通风增氧 系统的螺旋式翻拌机。

本发明的有益效果是， 由于支通风管安装在翻拌装置的内侧或后面， 达到提高翻 拌、 行走的稳定性， 不容易发生倾覆现象， 发酵物料的厚度可以增加。 本发明能够应 用于各种肥料、 饲料和食品等有机物料进行好氧发酵工艺， 实现对物料强制通风增氧 作业的带强制通风增氧系统， 在螺旋翻拌机在对发酵物料进行翻拌的同时， 能够保证 有与物料种类、 发酵时期和物料厚度相适应的压力和流量的空气从物料层中穿过， 真 正实现对物料的强制通风和增氧， 有效改善物料的发酵条件， 而且可明显增加发酵物 料堆积的厚度， 增加翻拌机行走的平稳性和安全性， 显著提高发酵效果， 可缩短发酵 周期， 提高发酵车间的周转率， 显著提高企业的经济效益。 附图说明 图 1为本发明的结构示意图。
