0引言传统烘干机进料装置多采用下料溜子,安装在沸腾炉出风口上部,由于沸腾炉出风口烟气温度较高,下料管即便采用耐热钢铸造,其见火部位也很容易被烧坏,更换频繁,严重影响了烘干机的正常运转。对于流动性特别差的物料,如煤泥、粉煤灰和石膏等,下料溜子还易发生堵料现象。少数厂家为避免堵料现象,采用螺旋输送机向炉内送料,该工艺弊病更多,如进
0 Introduction The traditional dryer feed device to use more material, installed in the upper part of the outlet of the boiling furnace, the boiling furnace outlet flue gas temperature is higher, even if the lower tube cast heat-resistant steel, the fire site can easily be seen Burn out, replace frequently, seriously affecting the normal operation of the dryer. For particularly poor liquidity of materials, such as slime, fly ash and gypsum, etc., cutting material is also prone to blocking phenomenon. A small number of manufacturers in order to avoid the blocking material phenomenon, the use of screw conveyor to feed the furnace, the process more ills, such as into
