隔膜压滤机与其他的压滤设备是有一些差别的，主要的区别就是它的内部有一个滤板膨胀系统，这个系统和其他设备的种类不同。它起着什么作用呢，下面让小编帮大家解答一下隔膜压滤机滤板膨胀系统的秘密。
当隔膜压滤机工作一定时间的时候，滤室中的滤饼已经装满滤布的时候，这是设备将不能继续进行固液分离的工作了，所以当滤饼填满整个滤室的时候，过滤后的液体就很难从滤布中渗析出来，所以这个时候隔膜压滤机的进料系统就会停止供料，供料孔就会暂时的封闭起来。这时候隔膜压滤机的滤板膨胀系统就会开始起作用了。
先是启动液压泵，然后将源源不断的液压油压入滤板当中，随之而来的就是隔膜滤板的中空空间就会积累一定体积的液压油，当液压油继续增多的时候，滤板就会向外膨胀，这是滤饼就会受到挤压，滤饼的体积就会减小，此时滤饼受到挤压之后就能将多余的液体排出来，这样就能够大大降低滤饼的含水率。这就是隔膜压滤机之所以能够有效降低滤饼含水率的秘密。
There are some differences between diaphragm filter presses and other filter presses. The main difference is that there is a filter plate expansion system inside, which is different from other types of equipment. What role does it play? Let Xiaobian help you answer the secrets of the membrane filter expansion system of the diaphragm filter press.
??When the diaphragm filter press works for a certain period of time, when the filter cake in the filter chamber is filled with the filter cloth, this is the work that the equipment will not be able to continue the solid-liquid separation, so when the filter cake fills the entire filter chamber The filtered liquid is difficult to seep out from the filter cloth, so at this time the feed system of the diaphragm filter press stops feeding and the supply hole is temporarily closed. At this point, the filter plate expansion system of the diaphragm filter will start to function.
??The first is to start the hydraulic pump, and then press the continuous hydraulic oil into the filter plate. Then, the hollow space of the diaphragm filter plate will accumulate a certain volume of hydraulic oil. When the hydraulic oil continues to increase, the filter plate It will expand outwards. This will cause the filter cake to be squeezed and the volume of the filter cake will be reduced. At this point, the filter cake will be squeezed and the excess liquid will be drained. This will greatly reduce the filter cake. Moisture content. This is the secret of the diaphragm filter press to effectively reduce the moisture content of the filter cake.
