The inner diameter of the circular tube is the same as that of the storage tank 1. The top of the outer wall of the semi-circular tube is symmetrically provided with inner grooves 14. The included angle between the two inner grooves 14 is 90 degrees. A second mounting hole 15 is provided in the middle of one end of the inner wall of the inner groove 14. The outer protrusion 12 and the inner groove 14 are compatible with each other and can be used to position and limit the installation of the receiving platform 4. A fixing screw 16 is installed inside the second mounting hole 15. One end of the fixing screw 16 is located inside the first mounting hole 13 and can be used to fix the installation of the receiving platform 4, which facilitates the installation and use of the receiving platform 4. The orientation of the receiving platform 4 can be adjusted according to actual use requirements.

[0022] A transmission rod 5 is installed between the bottom middle of the inner wall of the receiving platform 4 and the top middle of the inner wall of the storage tank 1. A spiral blade 6 is welded to the middle of the outer wall of the transmission rod 5. The cross-sectional diameter of the spiral blade 6 is smaller than the inner diameter of the bottom opening of the storage tank 1. By using the spiral blade 6, the bottom opening of the storage tank 1 can be sealed. A first locking hole 9 is opened at the bottom of the outer wall of the transmission rod 5. A feeding plate 7 is installed at the bottom of the outer wall of the transmission rod 5 near the first locking hole 9. A sleeve hole is provided on one side of the top of the feeding plate 7. The inner diameter of the sleeve hole is matched with the diameter of the transmission rod 5. A second locking hole 10 is opened in the middle of the sleeve hole. The inner diameter of the second locking hole 10 is matched with the inner diameter of the first locking hole 9.

[0023] The working principle and usage process of this utility model are as follows: The operator fixes the device inside the sewage treatment equipment. During the use of this utility model, the operator feeds activated carbon granules into the storage tank 1 through the feeding hopper 2. Then, the operator starts the reduction motor 8, which drives the transmission rod 5 to rotate. The spiral blade 6 and the feeding plate 7 rotate synchronously with the transmission rod 5. During the rotation of the spiral blade 6, the activated carbon granules inside the storage tank 1 can be discharged. The discharged activated carbon granules fall onto the receiving platform 4 under the action of gravity. When the activated carbon granules come into contact with the rotating feeding plate 7, the feeding plate 7 will throw the activated carbon granules into the sewage treatment equipment, thereby avoiding the activated carbon granules from accumulating in one place. This method can also reduce the difficulty for the operator to add activated carbon.
