This utility model relates to a structure for improving oil leakage in a plate
filter press, comprising a plate
filter press, wherein oil collecting ring grooves are provided on the overlapping end faces of the upper and lower adjacent stacked blocks of the plate
filter press, and the oil collecting ring grooves are connected to a main
pipe via hoses, and a negative pressure suction device is provided on the main
pipe. This structure for improving oil leakage in a plate filter press, by providing oil collecting ring grooves on the overlapping end faces of the upper and lower adjacent stacked blocks, ensures that lubricating oil leaking outward along the joints between the stacked blocks first reaches the oil collecting ring grooves, and is then suctioned into a collection container by negative pressure via hoses and the main
pipe, preventing leakage to the outside.
