How Filter Plate Broken1. When the sludge is too thick or leaves dry lumps, the feeding port will be blocked. At this time, there is no medium between the recessed filter plates, and only the pressure of the hydraulic system itself remains. At this point, the board itself is easily damaged due to prolonged stress. 2. When the feed is insufficient or the feed contains inappropriate solid particles, it will also cause the board and the frame itself to be overstressed and thus damaged. 3. If the outlet is blocked by solids, or the inlet valve or outlet valve is closed at startup, there will be no pressure leakage, resulting in damage. 4. When the chamber filter plate is not cleaned, sometimes the medium will leak. In the event of a leak, the edges of the board racks will be flushed into small trenches one by one. A large amount of medium leakage will result in no pressure rise and no mud cake formation.

Which kind of filter cloth is better?During the filtration process, the solid particles (fine particles) of the amorphousbb of the filter press and reduces the leakage of porous water between the filter plates of the filter press. The surface high temperature curing technology has a good effect on solving the practical problems of the filter press. Only the monofilament filter cloth can maintain a stable structure without deformation, but the impact resistance and compressive strength of the monofilament filter cloth are not higher than that of the multifilament filter cloth, which is easy to be damaged. At present, there are many typesv filter cloths on the market. According to different materials, there are many chemical fibers; in terms of structure, they are mainly textile and chemical fiber felt, cardboard and filter paper.The filter cloth used in the diaphragm filter press is "high temperature setting (calendering) filter cloth". After the high temperature setting (calendering) filter cloth, the shape of the pores between the cotton yarns changes from a positive bell mouth shape to a reverse bell mouth shape.Therefore, filter cloth manufacturers have produced monofilament and multifilament filter cloths to overcome the shortcomings of monofilament filter cloths. The monofilament filter cloth is used as the sealing layer, and the multifilament filter cloth is used as the support point layer. 

Why Filtered Cakes UnevenThere are two main reasons for the uneven mud cake pressed by the Chamber filter press.One is that the feed channel is blocked, that is, the feed hole in the center of the recessed filter plate is blocked by mud.Therefore, we must first check whether there is residual mud in the feeding channel, and rinse the channel to ensure smooth feeding.Second, the filter cloth is blocked (this could be judged by fast rising feeding pressure. The solution is that we wash PP filter cloth with a high-pressure water gun to ensure that the pores of the filter cloth are not blocked. Therefore, during the use of the filter press, we should regularly clean the filter cloth and feed holes to avoid such problems.
