What is the specific operating process of the plate and frame filter press for filtrate filtration?

1. The filtrate is first pumped into the feed pipe through the feed pump, and the feed pump gradually increases the filtrate in the feed pipe, allowing the filtrate to enter the two distribution pipes under high pressure conditions.

2. Connect the water distribution pipe to the two intake valve stems above the plate and frame filter press, allowing the filtrate to enter the two distribution pipes above the filter plate of the plate and frame filter press.

3. The material distribution pipe is formed by squeezing and splicing the filter plates one by one on the uniform direction side of each filter plate and leading to the concave channel or groove in the middle of the filter plate.

4. The filtrate in the filter plate and filter tube is divided into filter chambers composed of each filter plate and plate frame according to the above method, and is in contact with the filter cloth to achieve the filtration purpose. Filter out such a large amount of pressure.

5. At the end of filtration, collect the separated filtrate through the water pipe below the filter plate, and then discharge it from the drainage valve of a single filter plate to discharge the device.

The above steps cover the entire process from the filter press to the discharged filtrate. Although the discharged filtrate is transparent, it may not necessarily be clear water and needs to be solidified with liquid molecules.

Adopting the structural design of a plate and frame filter press, an effective pressure difference environment is formed on both sides of the medium. The medium can only allow liquid infiltration and intercept solids to be trapped in the medium, thereby achieving frame pressure. The basic principle of filter separation filter. In summary, they all use the isolation layer of plate and frame filter media to achieve the essence of solid-liquid separation.

The reason for different categories is that they handle filtering details in different ways. To illustrate this point, we explained the differences in filtering structures between them. Each flat plate filter press has the same opportunity, and the top of the filter plate is recessed to form a space for storing filter cakes, with both sides placed on filter cloths and connected in the middle. The combination of filter plates and filter cloths is compressed and connected to multiple filter plates and filter cloths of the same structure to form the same filter cloth space as the lifting rope, which is the filter chamber of the chamber filter press.
