Description

一种拨料式喂料机 技术领域
本发明涉及化学设备技术领域，尤其是涉及一种拨料式喂料机。
背景技术
流化床快速热裂解液化工艺要求对生物质进行干燥、粉碎和筛选处理，原料从料斗加入，经过进料器进入流化床反应器。以惰性气体(如氮气)充当的载气在压力作用下经过预热进入流化床反应器，气体在反应器内流化流化介质(如石英砂)，使生物质物料与高温流化介质充分混合至发生热裂解反应，生成的固体颗粒(炭)和热裂解气与载气一起流入旋风分离器进行气固分离。固体颗粒在离心力、器壁摩擦力及自身重力作用下落入集炭瓶，气体则进入冷凝器冷凝，可冷凝气体被冷凝成生物油，不可冷凝气体则被排出。
在生物质热裂解液化过程中，不但要求喂料的连续性和稳定性，还需要对生物质的喂料进行定量控制。螺旋喂料器是目前国内外最为常见的一种生物质输送机，具有结构简单、经济实用等特点，但因为生物质物料本身所具有的物性，在喂料过程中容易造成搭桥或挂壁现象，而且在连续喂料时反应器内的热载气会造成返料现象，导致均匀稳定输送物料不能顺利进行。另外，普通的螺旋喂料器无法满足定量喂料的要求，不能实现生物质的按需定量喂料。
发明内容
为克服上述问题，本发明采用如下技术方案：
一种拨料式喂料机，包括调速电机Ⅰ和调速电机Ⅱ，所述调速电机Ⅱ与拨料器连接，拨料器置于料斗内部，料斗下部与落料口相接，落料口置于机体上，机体内部设有螺旋蛟龙，所述机体左侧与调速电机Ⅰ相接。
所述落料口上方设有旋转杆。
所述落料口上方旋转杆的直径略大于落料口的直径。
本发明的优点是：结构简单，设计完善、合理，经济实用，密封性好，可以保持顺利喂料，且拨入物料量相对较少，避免了堵塞现象的发生。
附图说明
图1为本发明的结构示意图。
具体实施方式
如图1所示，一种拨料式喂料机，包括调速电机Ⅰ1和调速电机Ⅱ2，所述调速电机Ⅱ2与拨机体7上，机体7内部设有螺旋蛟龙6，所述机体7左侧与调速电机Ⅰ1相接。
所述落料口5上方设有旋转杆。
所述落料口5上方旋转杆的直径略大于落料口5的直径。
工作原理如下：
拨料式喂料器的料筒中安装了一个与调速电机Ⅱ2相连的翅片式拨料器4，可以保证物料在料斗3内由外向内被拨料器4拨入落料口5。为了避免物料自由落入落料口5，设计落料口5上方旋转杆的直径略大于落料5口的直径，使得物料只能由下面的拨料器4强制喂入。拨料器4的回转半径与料斗3的半径相近，它在旋转过程中会引起料斗3内的物料上下运动，防止物料堆积引起的搭桥或堵塞现象的发生。
在拨料器4的数量、宽度、回转半径和落料口5直径等参数确定的情况下，拨料式喂料器的喂料速率只取决于拨料器4的转速，且随拨料器4转速的增加而增大；通过调节调速电机Ⅰ1的转速，可以满足不同的喂料量要求。
料器4连接，拨料器4置于料斗3内部，料斗3下部与落料口5相接，落料口5置于
