The invention discloses a frame-type filter with a function of easily cleaning liquid leakage. The frame-type filter comprises a frame-type filter body and a collecting tank, wherein a first spray device and a second spray device are respectively arranged at two ends of the bottom of the frame-type filter; the collecting tank is arranged under the frame-type filter body; a first door body and a second door body are oppositely arranged above the collecting tank, and can be opened and closed; and the first door body and the second door body form a lambdoid shape and cover the collecting tank when being closed. The frame-type filter has the advantages that by using the filter, the pollution caused by liquid leakage in the filtering process can be greatly reduced, and staff cleaning workload after filtering is completed can be reduced.
