Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a dosing device for wastewater treatment. Background Technology
[0002] Chemical dosing equipment in wastewater treatment is mainly used to add chemical agents to wastewater to promote the sedimentation of suspended solids, inactivation of pathogens, and removal of phosphorus and nitrogen.
[0003] Existing dosing equipment can only concentrate dosing at specific points, which results in uneven distribution of the reagents and incomplete mixing with the wastewater. This not only affects the reaction efficiency and purification effect, but also indirectly slows down the overall wastewater treatment rate and limits the maximization of reagent efficiency.
[0004] Therefore, it is necessary to provide a dosing device for wastewater treatment. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, the present invention provides a dosing device for sewage treatment.
[0006] Technical solution: A dosing device for sewage treatment includes a hull, a propeller, a dosing tank, an inlet pipe, an outlet pipe, a worm gear, and a motor I. The propeller is installed on the left side of the hull, and the dosing tank is connected to the hull. The inlet pipe passes through the upper side of the dosing tank, and the outlet pipe passes through the bottom of the dosing tank. The worm gear is rotatably connected inside the outlet pipe. The motor I is installed on the hull, and the worm gear is connected to the output shaft of the motor I. A mixing mechanism is provided on the hull.
[0007] Furthermore, it is particularly preferred that the bottom center of the medicine box is funnel-shaped.
[0008] Furthermore, it is particularly preferred that the mixing mechanism includes a mixing frame, a water pump I, an inlet pipe, a water pump II, and an outlet pipe. The mixing frame is connected to the hull, and the outlet pipe is connected to the mixing frame. Water pump I is installed on the left side of the mixing frame, and an inlet pipe is connected to the inlet of water pump I. Water pump II is installed on the right side of the mixing frame, and an outlet pipe is connected to the outlet of water pump II. Both the outlet of water pump I and the inlet of water pump II are connected to the mixing frame.
[0009] Furthermore, it is particularly preferred that the mixing mechanism further includes a motor II and a mixing rod, with the motor II connected to the mixing frame and the mixing rod connected to the output shaft of the motor II.

[0011] In addition, it is particularly preferred that a ruler is also included, which is connected to the medicine box and is made of transparent acrylic material.
[0012] Beneficial effects:
[0013] This invention uses a pusher to start the water pump II11, which discharges the mixed medicine solution in the mixing frame 8 into the sewage through the outlet pipe 12, thereby purifying the sewage. During this process, the pusher 2 is started, which moves the hull 1 on the surface of the water, thereby changing the dosing position of the device, ensuring that the medicine solution can be fully mixed with the sewage, effectively improving the overall sewage treatment rate, and maximizing the utilization of the agent's efficacy.

[0019] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.
[0020] Example: A dosing device for wastewater treatment, such as... Figure 1 and Figure 2As shown, the device includes a hull 1, a thruster 2, a medicine box 3, a medicine inlet pipe 4, a medicine outlet pipe 5, a worm gear 6, and a motor I 7. The thruster 2 is mounted on the left side of the hull 1 via a fastener. The medicine box 3 is connected to the rear of the hull 1. The bottom of the medicine box 3 is funnel-shaped in the middle to facilitate the discharge of medicine. The medicine inlet pipe 4 for adding medicine powder is inserted through the upper side of the medicine box 3. The medicine outlet pipe 5 is inserted through the bottom of the medicine box 3. The worm gear 6 for transmitting medicine powder is rotatably connected inside the medicine outlet pipe 5. The motor I 7 is mounted on the rear of the hull 1 via bolts. The worm gear 6 is connected to the output shaft of the motor I 7 via a coupling. The hull 1 is equipped with a medicine mixing mechanism.
[0021] like Figure 2 and Figure 3 As shown, the mixing mechanism includes a mixing frame 8, a water pump I 9, an inlet pipe 10, a water pump II 11, and an outlet pipe 12. The mixing frame 8 is connected to the front of the hull 1, and the outlet pipe 5 is connected to the mixing frame 8. The water pump I 9 is installed on the left side of the mixing frame 8, and the inlet pipe 10 is connected to the inlet of the water pump I 9. The water pump II 11 is installed on the right side of the mixing frame 8, and the outlet pipe 12 is connected to the outlet of the water pump II 11. The outlet of the water pump I 9 and the inlet of the water pump II 11 are both connected to the mixing frame 8.
[0022] like Figure 2 and Figure 3 As shown, the mixing mechanism also includes a motor II 13 and a mixing rod 14. The motor II 13 is mounted on the mixing frame 8 by a fixing component, and the mixing rod 14 is connected to the output shaft of the motor II 13 by a coupling.
[0023] like Figure 4 As shown, it also includes a stirring roller 15, a rotating shaft 151 and a transmission assembly 16. The rotating shaft 151 is rotatably connected to the medicine box 3, and the stirring roller 15 is connected to the rotating shaft 151. The end of the rotating shaft 151 near the motor I7 is connected to the transmission assembly 16. The lower part of the transmission assembly 16 is connected to the output shaft of the motor I7. The transmission assembly 16 includes a belt and a pulley.
[0024] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a ruler 17. The medicine box 3 is connected to a ruler 17, which is made of transparent acrylic material. The amount of medicine powder inside the medicine box 3 can be clearly observed through the ruler 17.
[0025] When this device is needed, it should first be placed in the designated water area using a hoisting device. Then, add powder to the medicine tank 3 through the inlet pipe 4, and observe the amount of powder in the medicine tank 3 according to the scale 17. When the amount of powder in the medicine tank 3 reaches the required amount, stop adding the powder. At this time, the powder will enter the outlet pipe 5. Start motor I7. The output shaft of motor I7 will drive the worm gear 6 to rotate, thus pushing the powder forward into the mixing frame 8. Next, start water pump I9 to pump water into the mixing frame 8 through the inlet pipe 10. Then, start motor II13. The output shaft of motor II13 will drive the mixing rod 14 to rotate, causing the powder and water in the mixing frame 8 to mix thoroughly. After mixing is complete, start water pump II11 to discharge the mixed powder. The mixed medicine solution in frame 8 is discharged into the sewage through the outlet pipe 12 to purify the sewage. During this process, the pusher 2 is activated, which will move the hull 1 on the surface of the water, thereby changing the dosing position of the device to ensure that the medicine solution can be fully mixed with the sewage, effectively improving the overall sewage treatment rate and maximizing the utilization of the agent. When the output shaft of motor I7 rotates, the transmission component 16 will also drive the rotating shaft 151 to rotate, which in turn drives the stirring roller 15 to rotate, thereby speeding up the feeding speed and preventing the powder from clogging the channel between the medicine box 3 and the outlet pipe 5. After the dosing operation is completed, the device is turned off and the residual powder or medicine solution inside the device is cleaned. If the operation is required again, the above steps can be repeated.
[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
