The invention discloses a novel multi-functional cleaning agent processing device, which comprises a primary processing tank and a secondary processing tank. The secondary processing tank is arrangedon the bottom part of the primary processing tank; the primary processing tank is in sealed connection with the secondary processing tank; a fixed end cover is arranged on the top part of the primaryprocessing tank; a bearing base plate is arranged in the middle of the top part of the fixed end cover and the bearing base plate is fixedly connected with the fixed end cover; a linkage shaft rod isconnected to the top part of the bearing base plate; a rotary motor is rotatably connected to the top part of the linkage shaft rod; the linkage shaft rod extends into the primary processing tank; stiffener plates are fixedly connected to the upper side and the lower side of the linkage shaft rod; filter column rods are uniformly and equidistantly distributed on the inner sides of the stiffener plates; activated carbon bulged balls are uniformly and equidistantly distributed on the circumferential surfaces of the filter column rods. The device can be used for sufficiently mixing and stirring raw materials, can be used for filtering, sterilizing and disinfecting the raw materials, and has relatively high functionality.
