How does the filter press achieve filtration dehydration?

How does the filter press achieve filtration dehydration and drying? I think many people will ask this question. I will answer this question today.

For the working process of the filter press, we will briefly talk about it today, in one sentence:

1. The tight filter plate forms a closed filter space, and the filter cloth in the middle forms a filter cloth bag. Provide the necessary conditions and environment for filtering work.

2. The suspension is introduced into the filter chamber, and the pressure of the liquid is increased by the device, directly contacting the filter cloth, and the solid is intercepted by the filter plate.

3. After the filter residue of the filter chamber reaches a certain range, the feed is stopped, the device reverses the air, and the filter residue is squeezed again.

4. Pull the plate to remove the filter residue.

In order to achieve such a purpose. The filter press equipment must be improved as follows:

1. Improve the feeding mode. The design can repeat the feeding system, and each time it is single, it is also blown into the air filter to dry the filter cake.

2. Increase the pressure of the feed liquid by pulse feed method.

3. Improve the filter plate space design and increase the equipment's ability to store filter residue.

4. Improve the work message of the equipment, which can effectively filter the effective filtration area of ​​the filter and increase the area of ​​the filter cloth.

In general, the filter dewatering of the filter press equipment is a solid-liquid separation process, which is realized by the leakage interception of the filter cloth filter cloth. To achieve the filtration dewatering process, it is necessary to perfectly match the various parts of the equipment.
