Plate and frame type automatic filter press

How is the plate and frame press filtered?

The main advantages of the plate-frame filter press are less loss when feeding, fast filtration speed, high temperature and high pressure resistance, good sealing performance, uniform filter cake washing, low moisture content, and uniform pressure of each filter chamber is not easy to break the plate, basically suitable for all solid-liquid separation industry.

Filtering part

1. Filter part is made in a certain order in the filter plate on the girder, between filter plate filter cloth, filter plate, filter plate, filter cloth and filter plate and arranged, has formed a number of separate filtering unit ─ ─ at the start of the filter chamber filter, slurry under the impetus of the feed pump, the thrust plate of inlet into the interior, and feed pump of pressure filter.Due to the effect of the press cloth, the solid is left in the filter chamber to form a filter cake, and the filtrate is discharged by the nozzle (open flow) or the outlet valve (undercurrent) (see attached table 1 for the specification of the nozzle).

If the filter cake needs to be washed, the filter cake can be washed by washing water through the washing port on the thrust plate.If you need a filter cake with lower moisture content, you can also pass compressed air through the washing port to filter the cake layer to take away some water from the filter cake (for Uk model).If the compressed air or high-pressure liquid is pumped into the air inlet, the filter cake is pressed by stirring the diaphragm to further reduce the moisture content of the filter cake

2. The press cloth plays a key role in the use of the plate and frame filter press. Its performance and the correct selection directly affect the filtering effect.Among the filter cloth used, the most common is made of synthetic fiber textile, according to its material can be divided into polyester, polypropylene, polypropylene, polyamide and so on.

3. In addition, the commonly used filter media also include cotton cloth, non-woven cloth, screen, filter paper and microporous film, etc., according to the actual filtration requirements.
