隔膜滤板应用上的优点

Advantages of diaphragm filter plate application

•A=隔膜滤板过滤结束点 •B=厢式滤板过滤结束点 •C=隔膜滤板挤压后的湿度

•A=End point of diaphragm plate filtration •B=End point of box filter •C=Humidity of diaphragm filter plate after extrusion

1、过滤时间短，过滤板框以及厢式压滤机需要较长的过滤时间和过高的过滤压力才能达到较低的滤饼残余湿度， 隔膜滤板系统只需要很低的过滤压力就可以填满腔室。 

2、残余湿度低，过滤过程中所需要的高压过滤被高弹性膜片对滤饼挤压过程代替，在很短的时间内显著降低滤饼残余湿度，缩短整个过滤时间，提高过滤能力。 

3、膜片可更换，膜片可在压滤机内或压滤机外方便的更换，不需要更换整片滤板，只需要更换单片膜片。 

4、膜片弹性高，膜片由于弹性好，对于在过滤时形成的不均匀滤饼表面和不同堆积密度的滤饼，膜片能自身调节而不会产生变形，滤饼均匀，密度一致。

5、膜片材质选择，例如三元乙丙橡胶 EPDM,丁腈橡胶NBR，丁苯橡胶SBR，氟橡胶VITON，在膜片关键的受弯曲范围内采用特别的结构，以保证膜片*长的使用寿命。

6、橡胶膜片可定制，我公司也可根据贵公司需求定制橡胶膜片，或替代其他进口压滤机橡胶膜片。

1. The filtration time is short, the filter plate frame and the box type filter press need a long filtering time and a high filtering pressure to reach a low residual humidity of filter cake. The diaphragm filter plate system only needs a very low filtering pressure to fill the chamber.

2. The high pressure filtration is replaced by the extrusion process of filter cake by high elastic membrane, which can significantly reduce the residual humidity of filter cake, shorten the whole filtration time and improve the filtration capacity.

3. The diaphragm can be replaced, and the diaphragm can be easily replaced inside or outside the filter press. It is not necessary to replace the whole filter plate, but only a single diaphragm.

4. The membrane has high elasticity. Due to its good elasticity, the membrane can adjust itself without permanent deformation for the uneven surface of filter cake formed during filtration and filter cake with different packing density. The filter cake is uniform and dense.

5. Diaphragm material selection, such as EPDM, j-nitrile rubber, NBR, SBR, Viton, adopts special structure in the critical bending range of diaphragm to ensure the longest service life of diaphragm.

6. The rubber diaphragm can be customized. Our company can also customize the rubber diaphragm according to your company's demand, or replace the rubber diaphragm of other imported filter press.
