改选烘干机的方法1、加设中心X形扬料板，减少热空洞，延长物料停留时间，提高热交换效率，减少高温气体的流失。安装部位可从烘干机中部开始依次向机头端安装35组扬料板，间隔距离0.5~1m，每组6块X形扬料板。但靠近机头端3m内不能安装(因刚投入的物料水分高、黏度大、温度低，容易产生黏附)，否则会影响整体烘干效率。2、将进料端螺旋输送叶片去掉，改为三角形筋板，可用厚6mm钢板制作，短直角边高度与进料端挡圈同高度，并焊牢，长直角边长度为800mm，与烘干内筒焊牢，间隔50mm焊一圈，自然形成1个锥形进料器。其作用是减缓物料在高温带流速，并充分吸收热量，提高热交换率，并能够降低烘干机前端温度，避免烧坏筒体及挡料圈。3、改造进料管角度，只要不影响进料，尽可能将下料筒提高，以上端不与烘干机挡料圈接触为宜，但伸入筒体内部不可过长，控制落料点离挡料圈200mm以内。以防前端无料温度过高烧坏挡料圈与筒体，下料溜管提高后，既有利于高温气体的流通又防止烧坏溜管，物料自然下落形成料幕，与高温气体直接接触，热交换率提高。 4、改造机尾低温烘干带约筒体长度1/3处的L形扬料板，一般L形扬料板都是垂直90固定，周圈可依次按30;、90、120的角度焊接。这样通过烘干机旋转，扬料板在不同的空间高度，扬料分布面积大，热交换率高。注意烘干机改造是要综合考虑的，若通风好，废气温度高于100℃，可多设几组X形中心扬料板，反之，通风差，废气温度低于70℃，要减少几组X形中心扬料板。废气温度控制很重要，过高，一方面造成能耗高，另一方面会烧坏除尘袋；过低，会造成糊袋，影响通风，产量下降，除尘内部构件腐蚀严重，维修费高。5、烘干物料流速快，质量不好控制，可多设几组X形中心扬料板，但必须考虑通风及废气温度。若条件不允许，挡料圈设置多少及位置要根据具体情况，其缺点是挡料圈前部内筒体易磨损，可采用耐磨材料或加厚这一区域的钢板厚板来解决。For energy-saving dryer Re-election dryers method 1, adding center X to feed plate, reduce the hot hole, extend the stay time material, improve the efficiency of heat exchange, and reduce the loss of high temperature gas. Installation site can begin from the dryer in central head end set in turn 3 & ndash; 5 groups of feed plate, distance 0.5 ~ 1 m, 6 X feed board in each group. But near the nose end cannot be installed within 3 m (for has just gone into material moisture content, high viscosity, low temperature, easy to produce adhesion), otherwise it will affect the whole efficiency of drying. 2, will feed the spiral conveyor leaf, stiffened plates instead of the triangle, available 6 mm thick steel plate production, short square edge height with feed end collar height, and welded square edge length is 800 mm long, and in the drying cylinder welded, interval welding lap 50 mm, naturally formed a tapered feeder. Its action is slow materials in high-temperature belt velocity, and fully absorb heat, increase the rate of heat exchange, and can decrease the temperature of the dryer front-end, avoid damage cylinder and block
