Ceramic filter in vacuum pressure enough, the ceramic plate does not suck pulp, what is the reason for analysis?
The filtrate is not discharged smoothly.The filtrate can not be discharged in a timely and smooth manner, the new filtrate can not be sucked out, and the filtrate can not be continuously sucked out, so that the filter cake can not be adsorbed on the ceramic plate.
The spindle speed is too fast.The speed is too high to absorb the filter cake.There are other possible reasons.
The incoming mud content, fine particle size, pulp itself is not suitable for the use of ceramic filter dehydration, if the use of ceramic filter dehydration in this case, will accelerate the blockage of ceramic filter plate, blocking the situation after the second reference description.
Ceramic filter plate.The ceramic filter plate does not match the blockage or selection of new plate porosity is generally around 40%, such as ceramic filter plate has hole blocking, the opening rate will become less, when the suction effect into 30% relatively new plate may be slightly worse, when the ceramic filter plate is used for a long time after the opening rate is 10% or less, then the ceramic filter plate suction effect will become very poor even suction. At this time, even if the vacuum suction is good, also do not suck sizing, you need to replace the new ceramic filter board.
Generally, the vacuum degree of ceramic filter is about -0.08MPa. Sufficient vacuum pressure is only a prerequisite for a good ceramic suction effect. Besides vacuum, the other factors may affect the suction effect:Vacuum display table fault, the difference between the display value and the actual data is great.
