[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 3A wastewater treatment dosing device in this embodiment includes a base 1, a wastewater tank 2 fixedly installed on the top of the base 1, a dosing component 3 fixedly installed on the top of the wastewater tank 2, a discharging component 4 provided on the top of the wastewater tank 2, a stirring device 5 provided inside the wastewater tank 2, and a protective box 9 fixedly installed at the bottom of the wastewater tank 2.

[0024] The medicine discharge assembly 4 includes a housing 401 fixed to the top of the sewage tank 2. An electric telescopic rod 402 is fixedly installed on the bottom wall of the housing 401. A lifting plate 404 is fixedly installed at the telescopic end of the electric telescopic rod 402. A second motor 405 is fixedly installed at the top of the lifting plate 404. A rotating shaft 406 is fixedly installed at the output end of the second motor 405. A magnetic suction head 407 is fixedly installed at the top of the rotating shaft 406.

[0025] Specifically, when the staff activates the electric telescopic rod 402, the electric telescopic rod 402 drives the lifting plate 404 to move up and down, adjusting the height of the magnetic suction head 407. The magnetic suction head 407 rises and is attracted and fixed to the magnetic cap 6 of the medicine container sealing plug 307 (electromagnetic attraction), or falls and disengages (power off release). The second motor 405 drives the rotating shaft 406 to rotate forward or backward, driving the magnetic suction head 407 to rotate, thereby unscrewing or tightening the magnetic cap 6 to realize the dispensing or sealing of the medicine.

[0026] Specifically, the top of the sewage tank 2 is fixedly equipped with two high baffles 16 and two low baffles 17. The front and rear of the housing 401 are equipped with high baffles 16, and the left and right sides are equipped with low baffles 17. The distance between the high baffles 16 and the housing 401 on both sides is equal. The high baffles 16 and low baffles 17 surround the top of the sewage tank 2 to prevent the chemicals from splashing out of the tank during the dosing process.

[0027] Please see Figure 1 and Figure 2 In this embodiment, the dosing assembly 3 includes a first support leg 301 fixed to the top of the sewage tank 2, a third motor 302 fixedly installed on the top of the first support leg 301, a first rotating rod 303 fixedly installed at the output end of the third motor 302, a second support leg 304 fixedly installed on the top of the sewage tank 2, a sleeve 305 fixedly installed on the top of the second support leg 304, the first rotating rod 303 is rotatably connected to the sleeve 305, and a turntable 306 is fixedly installed on the side of the first rotating rod 303 away from the third motor 302. Four medicine tank sealing plugs 307 are threadedly connected to the turntable 306. The staff starts motor 302, which drives the first rotating rod 303 to rotate, causing the turntable 306 to rotate synchronously. Four threaded detachable medicine bottle sealing plugs 307 are evenly distributed on the turntable 306. By rotating, the target medicine bottle sealing plug 307 is aligned with the position directly above the medicine dispensing component 4, so as to achieve precise switching of different medicines. The second support leg 304 and the sleeve 305 provide rotational support for the first rotating rod 303, while ensuring the smooth operation of the turntable 306.

[0028] Specifically, a magnetic cap 6 is threadedly connected to the end of the medicine container sealing plug 307 away from the turntable 306. The magnetic cap 6 has two slots 7 inside. The magnetic cap 6 is connected to the medicine container sealing plug 307 by threads to ensure the medicine is stored in a sealed manner. When adding medicine, the magnetic cap 6 is attracted and fixed to the magnetic head 407 through the slots 7.

[0029] It should be noted that the four medicine bottle sealing plugs 307 inside the turntable 306 are spaced at the same interval.

[0030] It should be noted that the turntable 306 is divided into four equidistant cavity areas. Each area is connected to a medicine bottle sealing plug 307 by threads. When a specific medicine needs to be added, the operator rotates and removes the medicine bottle sealing plug 307 of the corresponding area, injects the medicine into the cavity through an external pump, and then reseals it after completion.

[0031] Please see Figure 1 and Figure 2 In this embodiment, the stirring device 5 includes a No. 4 motor 8 fixedly connected to the bottom wall of the protective box 9. The output end of the No. 4 motor 8 extends into the interior of the sewage tank 2 and is fixedly connected to a No. 2 rotating rod 10. A fixed rod 11 is rotatably connected to the end of the No. 2 rotating rod 10 away from the No. 4 motor 8. The fixed rod 11 is fixedly connected to the inner wall of the sewage tank 2. A stirring paddle 12 is fixedly connected to the surface of the No. 2 rotating rod 10. When the operator starts the No. 4 motor 8, the No. 2 rotating rod 10 rotates at high speed, thereby causing the stirring paddle 12 to rotate synchronously. The fixed rod 11 is connected to the inner wall of the sewage tank 2, which enhances the support strength of the No. 2 rotating rod 10 and prevents swaying or vibration during high-speed rotation.

[0032] Specifically, a support block 13 is fixedly installed on the bottom wall of the sewage tank 2. The support block 13 is ring-shaped, and its inner wall is rotatably connected to the outer wall of the second rotating rod 10. The support block 13 and the second rotating rod 10 form a rotatable connection, providing an additional bottom support point to prevent the second rotating rod 10 from shifting or bending due to stirring resistance.

[0033] It should be noted that the wastewater tank 2 has an inlet pipe 14 connected to its left side and an outlet pipe 15 connected to its right side. Both the inlet pipe 14 and the outlet pipe 15 extend from the outside of the wastewater tank 2 to its inside. The wastewater to be treated is introduced into the tank through the inlet pipe 14, and the treated water after mixing is discharged through the outlet pipe 15.

[0034] The working principle of the above embodiments is as follows:

[0035] Workers removed the corresponding medicine container sealing plug 307 from the turntable 306, added medicine to the corresponding area using a pump, resealed it after addition, and then started the third motor 302 in the dosing assembly 3, driving the first rotating rod 303 to rotate the turntable 306, switching the target medicine container sealing plug to directly above the discharging assembly 4. At the same time, the electric telescopic rod 402 in the discharging assembly 4 was activated, pushing the lifting plate 404 upward, so that the magnetic suction head 407 was aligned with the medicine container sealing plug 307. The magnetic cap 6 is attached and fixed. Then, the second motor 405 drives the rotating shaft 406 to rotate in the forward direction. At the same time, the electric telescopic rod 402 drives the lifting plate 404 to descend to the designated height, so that the medicine flows into the sewage tank 2 through the preset channel. After the medicine is added, the electric telescopic rod 402 pushes the lifting plate 404 to rise to the designated height. The second motor 405 drives the rotating shaft 406 to rotate in the reverse direction, returning the medicine tank sealing plug 307 to its position. Then, the magnetic head 407 is disconnected from the magnetic cap 6 and descends to the original height.

[0036] Wastewater is injected into wastewater tank 2 through inlet pipe 14. After the dosing is completed, the staff starts the stirring device 5. Motor 8 drives rotating rod 10 and stirring paddle 12 to rotate at high speed, so that the agent and wastewater are fully mixed. The treated wastewater is discharged through outlet pipe 15.
