物料进入烘干机进行干燥的过程,是物料充满烘干机在烘干筒内部不断反转的过程。反转之后的物料在与热量的充分交换之下得到干燥的效果。在这个过程之中,我们可能会忽略到一个问题,那就是烘干之后的物料由于其颗粒太过细小,所以有很有可能会有部分的物料残留在烘干机的内部,难以清洁排除。这种情况的出现很容易对烘干机再次进行物料烘干时造成质量的影响。因此要想从根本上解决这种问题,我们需要对烘干机的内部构造进行重新设计和研究。
  The process of material entering the dryer for drying is the process that the material filling dryer continuously reverses inside the drying drum. The material after reversal can be dried by fully exchanging heat. In this process, we may overlook a problem, that is, the material after drying is too small particles, so there is a high probability that some of the material will remain in the inside of the dryer, which is difficult to clean and eliminate. The emergence of this situation can easily affect the quality of the dryer when the material is dried again. Therefore, in order to solve this problem fundamentally, we need to redesign and study the internal structure of the dryer.
  平常我们看到的转筒烘干机的制造工艺都是较为简单的,其内部的筛板几乎都是水平环状布局的,解决上述问题我们需要进行重新的考核与测定,将多层水平环状筛板设计为螺旋面的径角为1.5°,从而能够较好地消除了本烘干设备干燥后残留在机体内部的物料问题。这种解决方案是从烘干机设备本身进行的彻底的改造,生产出的烘干机我们不必考虑会有什么后顾之忧,通过各种案例的分析,这种方案已经得到了很有效的实施,通过这种案例的实施,对于烘干机的日常的管理与清洁的工作,也具有很大的便利效果。内壁残留对于烘干机的本身的启动问题也会造成一定的影响,增大构件之间的摩擦,对于烘干机的整体的运转效果是一个很大的挑战。科技的进步使得烘干机的各项具有漏洞的方案措施都在得到有效的改进,各种问题在得到进一步的完善与改进。
  Usually we can see that the manufacturing process of rotary dryer is relatively simple, and the inner sieve plate is almost horizontal annular layout. To solve the above problems, we need to re-examine and test. The multi-layer horizontal annular sieve plate is designed as a helical surface with a diameter angle of 1.5 degrees, which can better eliminate the material problem left in the body after drying of this drying equipment. 。 This solution is a thorough transformation of the dryer equipment itself. We don't need to consider the worries behind the production of the dryer. Through the analysis of various cases, this solution has been effectively implemented. Through the implementation of this case, it is also very convenient for the daily management and cleaning of the dryer. Residual inner wall will also have a certain impact on the start-up of the dryer itself. Increasing friction between components is a great challenge to the overall operation effect of the dryer. With the progress of science and technology, all kinds of schemes and measures with loopholes in dryer have been effectively improved, and all kinds of problems have been further improved.
  褐煤烘干机的外部筒体是由钢材焊接而成的,在经过长时间的使用之后,钢材的焊接处很容易出现缝隙,也就是我们说的脱焊现象。对于褐煤烘干机这样的大型设备来说,也许小的缝隙并不会造成太大的影响,但时间久了就可能会出现我们意想不到的故障的发生。所以对于褐煤烘干机来说,焊接的小缝隙是不容忽视的。我们需要在褐煤烘干机的使用过程中,经常性的对褐煤烘干机进行检测,只有这样才能保证万无一失。   脱焊现象的发生,我们自然要想办法进行解决,根据一些有经验的烘干机用户我们收集到许多关于脱焊现象问题解决的办法,具体的方法且听我们一一进行介绍。

  The outer cylinder of lignite dryer is welded by steel. After a long period of use, cracks are easy to appear in the welds of steel, which is what we call de-welding phenomenon. For large equipment such as lignite dryer, small cracks may not cause too much impact, but over time, there may be unexpected faults. So for lignite dryer, the small gap in welding can not be ignored. We need to test the lignite dryer regularly in the process of using the lignite dryer. Only in this way can we ensure that there is no mistake. According to some experienced dryer users, we have collected a lot of solutions to the problem of de-welding. The specific methods and listen to our introduction.
  首先我们应该选择小直径的堆焊条和小电流焊接规范,进行分层堆焊。这样做的目的是减少热应力,避免发生严重的变形和裂纹。对烘干机其它的部位进行的保护措施。另外在进行正式的电焊时电焊机的搭铁要直接搭在辊筒上,切不可搭在轴上,以免电流流过褐煤烘干机的滚动轴承,产生火花,致使轴承的滚动体和滚道的表面烧损。安全的焊接措施必须要提前做好防范的工作。此外,还可以采用拆卸后修复法,就是将滚筒连轴一起全部拆卸下来,经车削修复后在安装到机器上使用。这样做比较麻烦,但是可以对烘干机进行一次比较全面的大检查,对于一些还未出现故障,但已经有精要破坏的趋势的部位做好提前防范措施。在进行焊接的过程中,我们要边焊接边用直尺样板对堆焊部位进行检查,以保证外形尺寸的合格。对于褐煤烘干机是这样,对于其他的烘干机类型亦是如此。焊接缝隙看是很小,但却隐藏着大问题,所以对于任何的小问题我们都不能轻易的放过,解决好小问题,才能避免大问题的出现。
  First of all, we should select small diameter surfacing rods and small current welding specifications for layered surfacing. The aim is to reduce thermal stress and avoid serious deformation and cracks. Protection measures for other parts of the dryer. In addition, during the formal welding, the lap iron of the welding machine should be directly laid on the roller, but not on the axle, so as to avoid the current flowing through the rolling bearing of the lignite dryer and sparks, resulting in the burning of the rolling body of the bearing and the surface of the raceway. Safe welding measures must be prevented in advance. In addition, the method of repairing after disassembly can also be used, that is, all the connecting axles of the drum can be disassembled together. After turning and repairing, the drum can be installed on the machine for use. It's more troublesome to do so, but we can make a comprehensive inspection of the dryer, and take precautions in advance for some parts that have not yet failed but have the tendency to destroy. In the process of welding, we need to inspect the surfacing position with a ruler sample while welding to ensure the conformity of the shape and size. This is true for lignite dryers and for other types of dryers. Welding gap is very small, but it hides big problems, so we can not easily let go of any small problems, solve small problems, in order to avoid the emergence of big problems.
