(1) The damage of the filter plate of the box filter press is a common fault.
If the number of filter plate damage is large, the following factors should be analyzed:
(1) Manufacturing quality of filter plate;
(2) Matching the material selection of the filter plate with the head of the feed pump;
(3) In the way of diaphragm pressing, both the quantity of oil filter and the quality of inner steel lining should be considered.
Under normal conditions, the pressure on both sides of the filter plate is in equilibrium. When the two sides of the filter plate are in different filtering stages, that is, one side is filtering and the other side is hydraulic extrusion, the pressure difference between the two sides of the filter plate forms, which damages the filter plate. The reasons are:
During the unloading process, the residual mud amount on both sides of the filter plate is quite different.
(2) After the filter press starts to filter, the feeding pump stops for a long time in the middle of the way, and the cake in the semi-flowing state of the filter chamber sinks to varying degrees;
(3) The feed hole of the filter plate is blocked.
(2) In the filtration operation of the automatic vacuum oil filter with spraying material between the filter plates, spraying material occurs between the filter plates. The reasons are as follows:
The filter cloth folds on the compression surface of the filter plate frame.
(2) The filter cloth is damaged;
(3) The lateral bending (horizontal direction) of the cross beams on both sides appeared to varying degrees.
(4) The thrust plate is not pressed or the pressure of the hydraulic cylinder is too small.
