Comprising a box body; the upper end of the box body is detachable; openings are formed in the two ends of the box body; a joint; the connectors are fixedly connected to openings in the two ends of the box body. Wherein olive oil to be filtered is connected into one connector; the other connector is used for discharging the filtered olive oil; a filter plate; the filter plate is fixedly connected to the interior of the box body; the filter plate comprises a square frame; the square frame is fixedly connected to the inner wall of the box body; a chute; the sliding grooves are formed in the two inner walls of the box body. The sliding grooves in the inner walls of the two sliding grooves are in one-to-one correspondence. The filter membrane is lapped on the buffer rod to form a corrugated shape; according to the invention, the impact force on the filter membrane is unloaded through the buffer rod and the spring, so that the impact of liquid on the filter membrane is reduced, the service life of the filter membrane is prolonged, and meanwhile, the self-cleaning purpose can be realized in the movement process of the filter membrane.
