Uniwin - Model BMY -Plate and Frame Filter Press

• Type: plate and frame/recessed filter press
• Capacity: 1-100 tons/hour
• Weight: 1-20 tons
• Size: 10*1.6*1.8 m
• Applications: coal washing, inorganic salt-mining, alcohol, petroleum chemical, dyestuff, metallurgy medicine, foodstuff, textile printing and dyeing, paper making, wastewater treatment, sewage treatment industries, etc.

The plate and frame filter press is mainly composed of a thrust plate, a compression plate, a filter plate and a filter frame, a beam, a filter medium (filter cloth), a compression device, a liquid collection tank, etc. The plates and frames are arranged alternately, and the two sides of the filter plates are covered with filter cloth. The plates and frames are pressed tightly by the hydraulic cylinder, and a filter press chamber is formed between the plates and frames. There are holes on the corners of the filter frame and filter plate, which form a complete channel after assembly, which can pass into the suspension, wash water, and lead out the filtrate.

The plate and frame press filter is batch operation, which means that the operation must be stopped to discharge the filter cake before the next batch can be started. The filtering cycle usually takes from 20 minutes to 3 hours, depending on the different characteristics of the filtering material. In contrast, the vacuum belt filter can work continuously. If your processing volume is too large, you can also consider the vacuum belt filter.

Filter Plate and Frame Sizes:

The sizes of our filter plates size are 320, 450, 630,800,1000,1250,1500 and 2000 mm. We can also customize the size of the plates depending on clients’ requirements.

Available Materials of  filter plates:

• Polypropylene/PP
• Stainless steel 304 or 316L
• Cast Iron

The process of one batch filtration is as follows:

1. Closing of the filter plates and frames: when starting the press button on the PLC control cabinet, the moving head plates will be activated by the hydraulic calmps the plates.
2. Filling: The sludge (or slurry) will be pumped into the chamber one by one. When all chambers are full of filter cakes, the filtration is finished.
3. Filter plates and frames opening: The moving head is drawn back to disengage the first filtration chamber. The cake falls will drop from the plates/frames because of gravity. The auto-pulling system pulls out the plates one by one.
4. Filter cloth Washing: Usually, washing of clothes should be carried out every 15-100 batches. A filter press with a filter cloth washing system can greatly improve efficiency.

The automatic plate pulling system and filter cloth washing system mentioned above are additional functions of the fully automatic plate and frame filter press. Compared with ordinary filter presses, the fully automatic filter press can greatly improve efficiency. The automatic pulling plate can pull one or more filter plates at a time to unload the filter cakes, and the filter cloth washing system can automatically clean the filter cloth, significantly reducing time and labor costs.
