The outer wall of the sliding ring 10 is slidably sleeved with a first sliding groove, and the first sliding groove is opened on the inner wall of the medicine barrel 6. A plurality of connecting rods 11 are fixedly installed at the connection between the outer wall of the barrel shaft 8 and the inner wall of the inner ring 9, and a plurality of second rotating rods 12 are vertically fixedly installed on the outer wall of the barrel shaft 8, and the plurality of second rotating rods 12 are located inside the medicine barrel 6. A sealing ring is sleeved on the outer wall of the lower side of the barrel shaft 8, and the sealing ring is fixedly installed at the connection between the inner cavity at the bottom end of the medicine barrel 6 and the inner cavity at the side end of the U-shaped frame 1;

[0032] The driving assembly includes a motor 13 fixedly mounted on the top of the U-shaped frame 1, and the driving end at the bottom of the motor 13 is vertically connected to two first gears 14 through a rotating shaft, and the rotating shaft is slidably sleeved in the inner cavity of the U-shaped frame 1, and the two first gears 14 are both located below the top of the U-shaped frame 1, and the side end of the lower first gear 14 is meshed with a second gear 15, and the second gear 15 is fixedly sleeved on the outer wall of the vertical rod 2. The driving assembly also includes a third gear 16 fixedly mounted on the bottom of the barrel shaft 8, and a toothed belt 17 is meshed at the connection between the outer wall of the upper first gear 14 and the outer wall of the third gear 16.

[0034] See also Figure 1 and Figure 3 A pump body 19 is provided in the middle of the conduit 7, and an electronic valve 20 is provided at one end of the conduit 7 close to the medicine barrel 6. The pump body 19 is fixedly installed on the outer wall of the medicine barrel 6 through a connecting plate. Bottom plates are fixedly installed on both sides of the bottom of the U-shaped frame 1, and bolts are threaded through both sides of each bottom plate. A controller 21 is fixedly installed on one side wall of the U-shaped frame 1 close to the medicine barrel 6.

[0035] The implementation principle of this embodiment is: when in use, the whole is placed on the top of the sewage pool, and the bottom plate and bolts arranged on both sides of the bottom of the U-shaped frame 1 are used to realize the fixed assembly work on the top of the sewage pool, and at this time the whole presents as follows Figure 4 In the state shown, the controller 21 is electrically connected to the motor 13, the pump body 19, and the electronic valve 20 through wires (which can be realized by programming, which is a prior art and will not be described in detail here);

[0036] When the medicine used for sewage treatment in the sewage pool is added into the medicine barrel 6, a proper amount of water source is added into it, and then the motor 13 is started to make the two first gears 14 run synchronously.

[0037] Afterwards, the electronic valve 20 and the pump body 19 are controlled to be opened, and the liquid medicine in the medicine barrel 6 is slowly input into the flow channel 3 of the vertical rod 2 by the conduit 7. Due to the centrifugal force of the rotation of the vertical rod 2, the liquid medicine in the flow channel 3 is mixed into the sewage in the sewage pool through the multiple through holes 5, and the multiple first rotating rods 4 are used to achieve a full and uniform mixing of the sewage and the liquid medicine, thereby achieving the treatment of the sewage;

[0038] When treating the sewage in the sewage pool, it is necessary to control the sewage level in the sewage pool, that is, to ensure that at least the uppermost through hole 5 is exposed above the sewage level.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
