隔膜壓濾機(jī)與其他的壓濾設(shè)備是有一些差別的，主要的區(qū)別就是它的內(nèi)部有一個濾板膨脹系統(tǒng)，這個系統(tǒng)和其他設(shè)備的種類不同。它起著什么作用呢，下面讓小編幫大家解答一下隔膜壓濾機(jī)濾板膨脹系統(tǒng)的秘密。
當(dāng)隔膜壓濾機(jī)工作一定時間的時候，濾室中的濾餅已經(jīng)裝滿濾布的時候，這是設(shè)備將不能繼續(xù)進(jìn)行固液分離的工作了，所以當(dāng)濾餅填滿整個濾室的時候，過濾后的液體就很難從濾布中滲析出來，所以這個時候隔膜壓濾機(jī)的進(jìn)料系統(tǒng)就會停止供料，供料孔就會暫時的封閉起來。這時候隔膜壓濾機(jī)的濾板膨脹系統(tǒng)就會開始起作用了。
先是啟動液壓泵，然后將源源不斷的液壓油壓入濾板當(dāng)中，隨之而來的就是隔膜濾板的中空空間就會積累一定體積的液壓油，當(dāng)液壓油繼續(xù)增多的時候，濾板就會向外膨脹，這是濾餅就會受到擠壓，濾餅的體積就會減小，此時濾餅受到擠壓之后就能將多余的液體排出來，這樣就能夠大大降低濾餅的含水率。這就是隔膜壓濾機(jī)之所以能夠有效降低濾餅含水率的秘密。
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.
