What are the washing methods of the filter cloth of the plate frame filter press?
According to the introduction of the filter press manufacturer, the washing methods of the filter cloth of the plate frame filter press mainly include the following:
1. The one-way flow washing of dark tide is that the washing liquid enters the perforated plate from the washing liquid inlet hole of the thrust plate, passes through the filter cloth, and then passes through the filter cloth, and flows out from the non-perforated filter plate.
2. Dark tide two-way washing means that the washing liquid is washed twice from the two washing liquid inlet holes on both sides above the stop plate, that is, the washing liquid is washed from one side first, and then from the other side. The outlet of the washing liquid is in the diagonal direction, so it is also known as dark tide two-way interleaving washing.
3. Open flow one-way washing means that the washing liquid enters from the washing liquid inlet hole of the thrust plate in sequence, passes through the filter cloth and then passes through the filter cloth, and flows out from the non-porous filter plate. At this time, the liquid outlet nozzle of the perforated plate is closed, and the liquid outlet nozzle of the non-perforated plate is open.
4. Open flow two-way washing is that the washing liquid is washed twice from the washing liquid inlet holes on both sides above the thrust plate, that is, the washing liquid is washed from one side first and then from the other side. The outlet of the washing liquid and the inlet are diagonal directions, so it is also called two-way interleaved washing.
The above is the detailed explanation of the filter press manufacturers on the washing methods of the filter cloth of the plate and frame filter press.
