Novel gravity disc type thickener

The utility model relates to the technical field of concentrators, and discloses a novel gravity disc type concentrator which comprises a rack, a filter cartridge is arranged in the rack, one side surface of the filter cartridge is rotatably connected with a rotating shaft, one end of the rotating shaft is provided with a motor, and the other end of the rotating shaft is rotatably connected with a hollow shaft. A rotating disc is arranged on the outer surface of the hollow shaft, and a feeding hopper is arranged on the upper surface of the machine frame. The slurry feeding device has the following advantages and effects that when the slurry feeding device is used, feeding is conducted on the feeding pipe through the feeding hopper, slurry is discharged through the positioning hoppers through the transverse pipe, and due to the fact that the multiple positioning hoppers are evenly distributed on the lower surface of the transverse pipe, the slurry can evenly fall on the outer surface of the rotating disc; when
