At present, many friends who do not know about filter press equipment think that the plate and frame filter press and the diaphragm filter press are the same machine. In fact, there are differences between the two. Here, Tianli Machinery will give you a detailed introduction. The difference between plate and frame filter press and diaphragm filter press:

The basic principle of the plate and frame filter press and the diaphragm filter press, the same structure, the difference is that the filter plate used in the diaphragm filter press is double and has a diaphragm cavity. The diaphragm filter plate and the filter plate with the same shape are arranged at intervals to form Each filter chamber with a certain volume, when the material is filtered, inject a certain pressure of gas (liquid) into the diaphragm cavity to make the diaphragm bulge and spin the filter cake in the opposite direction to achieve the purpose of reducing the moisture content of the filter cake.

Compared with the filter plate of the general box or frame filter press, the diaphragm filter plate has 2 filters and a diaphragm that can be moved back and forth. When the press medium (such as compressed air) is passed through the back of the diaphragm, these can be moved. The diaphragm will bulge in the direction of the filtration chamber, that is to say, after the filtration process is over, the filter cake will be squeezed again under high pressure. The moisture content of the filter cake can be 10-40% lower than that of the general filter plate. It can save you a lot of follow-up costs (see benefit analysis for details).

At the same time, when the filter cake is washed, it can be squeezed by the diaphragm to reduce the amount of washing water, and the effect is better.

The above is the difference between the plate and frame filter press and the diaphragm filter press. I hope it can help everyone. If you want to know more about the diaphragm filter press, you can pay more attention to this website.
