The utility model discloses a vibrating screen filtering device, and relates to the technical field of oil drilling devices. The vibrating screen filtering device comprises a liquid inlet groove assembly, a screening box, a backward-turning plate device and a middle diversion plate, wherein the middle diversion plate is arranged between an upper screen inside the screening box and a lower screen inside the screening box, the backward-turning plate device is hinged to a screening box lifting device, the liquid inlet groove assembly comprises a first liquid inlet groove, a second liquid inlet groove and a third liquid inlet groove which are formed in parallel, each liquid inlet groove is provided with a movable insertion plate, the liquid inlet of the second liquid inlet groove is formed above the upper screen, the liquid inlet of the first liquid inlet groove and the liquid inlet of the third liquid inlet groove are formed between the middle diversion plate and the lower screen, and the backward-turning plate device is arranged on one side of the lower end of the middle diversion plate. By opening a movable valve plate, opening and closing the movable insertion plate and adjusting the inclination degree of the backward-turning plate device, mud is guided to the upper screen or simultaneously guided to the upper screen and the lower screen, classified filtering and parallel filtering are achieved for mud, the screen area or the number of layers of the screens is increased for mud, and the filtering effect is enhanced. The vibrating screen filtering device has the advantages of being simple in structure and good in filtering effect.
