[0021] In order to make the purpose and advantages of this utility model clearer, the following will specifically describe this utility model with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of this utility model, and does not strictly limit the specific scope of protection requested by this utility model.

[0022] AsFigure 1 As shown in the figure, a chemical dosing device for sewage treatment includes a container 1. The interior of the container 1 stores chemicals, which can be liquid chemicals or granular solid chemicals, preferably solid chemicals.

[0023] A rotary feeding assembly is provided at the lower part of the container 1, which can feed the interior of the container 1 during rotation. A hydraulic wheel 9 connected to the rotary feeding assembly is assembled at the lower part of the container 1. During the flow of sewage, rotational kinetic energy will be transmitted to the hydraulic wheel 9. When the hydraulic wheel 9 rotates, it will input rotational kinetic energy to the rotary feeding assembly, enabling the rotary feeding assembly to automatically dispense the chemicals inside the container 1 when the sewage is flowing and automatically stop dispensing the chemicals when the sewage stops flowing.

[0024] Among them, as Figure 1-2 shown, the rotary feeding assembly includes a feeding pipe 2 fixedly connected to the lower side of the container 1. A rotating shaft 7 is rotatably connected inside the feeding pipe 2. One end of the rotating shaft 7 extends outside the feeding pipe 2 and is connected to the hydraulic wheel 9, enabling the hydraulic wheel 9 to drive the rotating shaft 7 to rotate. A feeding wheel 3 located inside the feeding pipe 2 is fixedly connected to the outer side of the rotating shaft 7. The feeding pipe 2 and the feeding wheel 3 are in clearance fit and can block the opening of the feeding pipe 2. A feeding groove 4 is formed on the outer circumferential surface of the feeding wheel 3. When the feeding groove 4 rotates to face the container 1, the chemicals inside the container 1 will enter the interior of the feeding groove 4. When the feeding groove 4 rotates to the lower side, the chemicals inside the feeding groove 4 can be discharged and dropped into the sewage below.

[0025] As Figure 2-3 shown, in order to control the dosage of the chemical, a screw 6 is rotatably connected inside the feeding groove 4. A top plate 5 that is in clearance fit with the feeding groove 4 is threadedly connected to the outer side of the screw 6, and the top plate 5 can slide inside the feeding groove 4. When the screw 6 rotates, adjusting the position of the top plate 5 can adjust the depth of the feeding groove 4 and control the amount of chemicals that can be stored inside the feeding groove 4.

[0026] As Figure 1 shown, the number of hydraulic wheels 9 is two. One hydraulic wheel 9 is installed below the front side of the container 1 through a support arm 8, and the other hydraulic wheel 9 is installed below the rear side of the container 1 through another support arm 8. Both hydraulic wheels 9 are connected to the rotating shaft 7 through a belt transmission assembly 10. When the sewage starts to be discharged, the sewage contacts the front hydraulic wheel 9, which will start the rotary feeding assembly in advance, enabling the container 1 to dispense chemicals in advance and reducing the amount of sewage that does not contact the chemicals. When the sewage discharge is completed, the container 1 will not stop dispensing chemicals until the rear hydraulic wheel 9 stops rotating, further reducing the amount of sewage that does not contact the chemicals.

[0027] Meanwhile, both of the two belt assemblies 10 are connected to the rotating shaft 7 through one-way bearings, enabling the hydraulic wheel 9 to drive the rotation of the rotating shaft 7, while the rotating shaft 7 cannot drive the rotation of the hydraulic wheel 9.

[0028] Please refer to Figure 1 As shown, in order to adjust the position of the hydraulic wheel 9, the support arm 8 is rotatably connected to the rotating shaft 7. A driving arm 11 is fixedly connected to one end of the support arm 8 away from the hydraulic wheel 9. When the driving arm 11 rotates, it will drive the support arm 8 to rotate together. A waist slot 12 is formed on the driving arm 11. A self-locking vertical moving member 15 is fixedly connected to the container 1. A sliding seat 14 is assembled on the self-locking vertical moving member 15. The self-locking vertical moving member 15 can drive the sliding seat 14 to move vertically. Two round rods 13 are fixedly connected to the sliding seat 14. The two round rods 13 are respectively slidably connected inside the two waist slots 12. When the sliding seat 14 moves, it will simultaneously pull the two driving arms 11 through the two round rods 13, adjusting the angles of the two support arms 8, thereby adjusting the position of the driving arm 11.

[0029] Please refer to Figure 1 and Figure 4 As shown, the self-locking vertical moving member 15 includes a vertical rail 16 fixedly connected to the container 1. A motor 19 is fixedly connected to the upper side of the vertical rail 16. The output end of the motor 19 is fixedly connected to a lead screw 18. A carriage 17 that is threadedly connected to the lead screw 18 and slidably connected to the vertical rail 16. By driving the lead screw 18 to rotate through the motor 19, the carriage 17 can slide on the vertical rail 16 to adjust the position of the carriage 17. The carriage 17 is fixedly connected to the sliding seat 14.

[0030] Meanwhile, the self-locking vertical moving member 15 can also be an electric push rod connected to the sliding seat 14, and the electric push rod can drive the sliding seat 14 to move.

[0031] The working principle of this utility model is as follows: During the flow of sewage, the flowing sewage will transmit rotational kinetic energy to the hydraulic wheel 9. When the hydraulic wheel 9 rotates, it will input rotational kinetic energy to the rotary feeding assembly, enabling the rotary feeding assembly to automatically dispense the medicament inside the container 1 when the sewage is flowing and automatically stop dispensing the medicament when the sewage stops flowing.

[0032] In summary, through the setting of the rotary feeding assembly and the hydraulic wheel 9, this technical solution can utilize the flow of sewage to automatically dispense the medicament inside the container 1, thereby being able to automatically dispense the medicament when the sewage is discharged and automatically stop dispensing the medicament when the sewage discharge stops.

[0033] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special description and limitation.
