How to Clean the Filter Cake?

The active ingredient in the filter cake can be further recovered by washing or the harmful components can be removed. Wash off the acidic or alkaline material above. When the washing solution is neutral, the filter cake is washed clean. Chamber Filter Press Factory believes that the filter press filter can be washed in the following ways:

1. The dark flow unidirectional flow 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 cake, and flows out from the non-porous filter plate.

2. The undercurrent two-way washing is that the washing liquid is washed twice from the two washing liquid inlet holes on both sides above the stopping plate, that is, the washing is first washed from one side and then washed from the other side, and the outlet of the washing liquid is diagonal. Direction, so it is also called undercurrent two-way cross washing.

3. The clear flow one-way washing is that the washing liquid enters sequentially from the washing liquid inlet hole of the thrust plate, passes through the filter cloth and then passes through the filter cake, and flows out from the non-porous filter plate, at which time the liquid discharging nozzle of the orifice plate is closed. In the state, the outlet nozzle of the non-porous plate is open.

4. The clear flow two-way washing is that the washing liquid is washed twice from the washing liquid inlet holes on both sides of the thrust plate, that is, the washing liquid is washed from one side and then from the other side, and the outlet of the washing liquid is the same as the inlet. The direction of the corner, so it is called two-way cross washing.
