Filter press working video demonstration

What is a membrane filter press?

The appearance of the chamber diaphragm filter press is similar to that of ordinary chamber filter press or plate and frame filter press, and the function of its frame system is also similar. The main difference between the diaphragm filter press and the ordinary box filter press is that a layer of elastic membrane diaphragm plate is installed between the filter plate and the filter cloth. During the operation, when the feeding is finished, the high-pressure fluid medium can be injected between the filter plate and the diaphragm, and the entire diaphragm will bulge to press the filter cake, thereby achieving further dehydration of the filter cake, that is, press filtration. The diaphragm box filter press with automatic water washing filter cloth is based on the previous one, plus a set of automatic cleaning device, so that the whole machine can realize fully automatic operation. The filter cake filtered by this machine has low water content, and the automatic pulling trolley does not need to manually unload the cake. After the solid-liquid separation is completed, the filter cloth can be automatically washed with water through the PLC control cabinet. It is very suitable for factories that need to work 24 hours a day, saving labor and labor costs.

Advantages of membrane filter press：

1. Increase the degree of mud biscuit and reduce the content of mud cake. The diaphragm press performs a second press on the filter cake after static filtration, so that the structure of the filter cake is rearranged and the density is increased, thereby displacing part of the water and improving the dryness. Spend.
2. Save the consumption of operating power. In the later stage of filtration, the flow rate is small, the pressure is high, and the power consumed by the feed pump is also high. The diaphragm pressing function is used to complete this process in a very short time, saving power consumption.
3. Increase the operating flexibility of the filter press, especially the operation that requires mud cake cleaning.
4. Significantly shorten the filtration operation time. In the later stage of filtration, the filtration efficiency is extremely low, and the diaphragm pressing function is used to complete this process in a very short time, and the efficiency is greatly improved.
5. Improve the processing capacity of the filter press.
6. Acid-resistant and alkali-resistant, the use temperature is higher, generally can be used at a temperature of about 230, the application is more extensive, and it is basically suitable for all solid-liquid separation operations.
