Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chemical dosing technology, and specifically relates to a chemical dosing mechanism for sewage treatment operation and maintenance. Background Technology
[0002] Chemical dosing plays a crucial role in wastewater treatment. It involves adding chemicals to wastewater to improve treatment efficiency and remove suspended solids, organic matter, pathogens, and other pollutants. Proper chemical dosing ensures that wastewater meets discharge standards, protecting water resources and public health. Therefore, chemical dosing systems are used in the operation and maintenance of wastewater treatment facilities.
[0003] The existing utility model with authorization announcement number CN210825473U discloses a sewage treatment agent dosing device, including a sewage tank, a transparent glass plate on one side of the sewage tank, a scale groove on one side of the transparent glass plate, a water inlet mechanism fixedly connected to the upper side of the sewage tank and located above the scale groove, and a dosing mechanism fixedly connected to the upper end of the sewage tank at an oblique angle opposite to the water inlet mechanism.
[0004] The above technical solution involves adding chemicals to the wastewater tank via a dispensing mechanism, followed by thorough mixing of the chemicals and wastewater by a stirring mechanism to dilute the chemicals before discharge. This effectively reduces the energy consumption of the wastewater treatment device, promotes energy conservation, and ensures that the treated wastewater meets the secondary wastewater discharge standard, significantly reducing potential environmental hazards. The amount of wastewater treatment chemicals added can also be controlled, and the added chemicals can be fully dissolved. However, when using this technical solution, the chemicals can only be dispensed at one location, which is too limited and may result in a low chemical dissolution rate.
[0005] Therefore, it is necessary to design a chemical dosing mechanism for wastewater treatment operation and maintenance to solve the problems mentioned in the background technology. Summary of the Invention
[0006] The technical problem to be solved by this utility model is to provide a chemical dosing mechanism for sewage treatment operation and maintenance, which effectively avoids the problem that the chemical dosing point is too singular when the device is in use, which may result in a slow chemical dissolution rate.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0008] A wastewater treatment operation and maintenance agent dosing mechanism, comprising:
[0009] It includes a processing cylinder, and a multi-point dispensing mechanism is installed on top of the processing cylinder;
[0010] The multi-point dispensing mechanism includes a stepper motor and a connecting pipe. The outer surface of the connecting pipe is fixedly connected to the inner wall of the processing cylinder. A rotating shaft is fixedly connected to the output end of the stepper motor. The outer surface of the rotating shaft is rotatably connected to the inner wall of the processing cylinder. A first gear is fixedly connected to the outer surface of the rotating shaft. A second gear meshes with the outer surface of the first gear. A rotating shaft is fixedly connected to the inner wall of the second gear. The outer surface of the rotating shaft is rotatably connected to the inner wall of the processing cylinder. A rotating ring is rotatably connected to the inner wall of the processing cylinder. A toothed ring is fixedly connected to the bottom surface of the rotating ring. The outer surface of the toothed ring meshes with the outer surface of the second gear. A first connecting plate is fixedly connected to the bottom end of the toothed ring. A circular cylinder is fixedly connected to the outer surface of the first connecting plate. The top end of the circular cylinder contacts the bottom end of the processing cylinder. A second connecting plate is fixedly connected to the outer surface of the circular cylinder. The inner wall of the second connecting plate is rotatably connected to the outer surface of the rotating shaft. A discharge pipe is fixedly connected to the bottom end of the circular cylinder. A first solenoid valve is fixedly connected to the outer surface of the discharge pipe.
[0011] Preferably, a connecting block is fixedly connected to the outer surface of the processing cylinder, and a storage tank is fixedly connected to the outer surface of the connecting block.
[0012] Preferably, the top of the storage tank is fixedly connected to an injection pipe, and the outer surface of the injection pipe is threadedly connected to a threaded cap.
[0013] Preferably, a metering pump is fixedly connected to the top of the processing cylinder, the upper surface of the connecting block, and the top of the storage tank. The input end of the metering pump is fixedly connected to a drug extraction pipe, the bottom end of which penetrates into the interior of the storage tank. The output end of the metering pump is fixedly connected to a drug dispensing pipe, the bottom end of which penetrates into the interior of the connecting pipe.
[0014] Preferably, a fixed base is fixedly connected to the outer surface of the stepper motor, the bottom surface of the fixed base is fixedly connected to the top of the processing cylinder, and six sets of stirring rollers are fixedly connected to the outer surface of the rotating shaft.
[0015] Preferably, an inlet pipe and a outlet pipe are fixedly connected to the outer surface of the treatment cylinder, and a second solenoid valve is fixedly connected to the outer surface of both the inlet pipe and the outlet pipe.
[0016] The present invention can achieve the following beneficial effects:
[0017] This invention incorporates a stepper motor that drives a fixed shaft at its output end to rotate. A first gear is fixed to the outer surface of the shaft. The meshing relationship between the first and second gears drives the second gear to rotate. A gear ring meshes with the outer surface of the second gear. Therefore, the rotational power generated by the stepper motor is transmitted to the gear ring through a series of force transmissions. Since the gear ring and the first gear are connected via the second gear, the rotation direction of the gear ring is completely opposite to that of the first gear. This causes a circular cylinder fixed to the outer surface of the first connecting plate to rotate around the shaft, evenly dispensing the agent inside the treatment cylinder. This effectively avoids the problem of slow agent dissolution rates caused by a single agent dispensing point during use. Attached Figure Description

A rotating ring 207 is rotatably connected to the inner wall of the processing cylinder 1. A metering pump 12 is fixedly connected to the top of the processing cylinder 1, the upper surface of the connecting block 6, and the top of the storage tank 9.

By setting up the metering pump 12, the drug stored inside the storage tank 9 can be extracted using the metering pump 12 and the drug extraction pipe 8, and discharged into the interior of the connecting pipe 203 through the drug outlet pipe 7.
[0027] A gear ring 206 is fixedly connected to the bottom surface of the rotating ring 207. The outer surface of the gear ring 206 meshes with the outer surface of the second gear 205. A first connecting plate 211 is fixedly connected to the bottom end of the gear ring 206. A cylindrical cylinder 210 is fixedly connected to the outer surface of the first connecting plate 211.

[0029] The working principle of this utility model is as follows: In use, the metering pump 12 first extracts the medicine stored inside the storage tank 9, drawing a specified amount of medicine into the cylindrical cylinder 210. Then, the stepper motor 201 is controlled to run. The stepper motor 201 drives the fixed output shaft 202 to rotate. A first gear 208 is fixed to the outer surface of the shaft 202. Utilizing the meshing relationship between the first gear 208 and the second gear 205, the second gear 205 can be driven to rotate. Furthermore, a gear ring 206 meshes with the outer surface of the second gear 205. Therefore, the rotational power generated by the stepper motor 201 is transmitted to the gear ring 206 through a series of force transmissions. Since the gear ring 206 and the first gear 208 are connected via the second gear 205, the gear ring 206 rotates. The direction of rotation is completely opposite to that of the first gear 208, which drives the circular cylinder 210 fixed on the outer surface of the first connecting plate 211 to rotate around the rotating shaft 202. Then, the first solenoid valve 213 is opened to allow the medicine inside the circular cylinder 210 to flow into the processing cylinder 1. This allows the medicine to be evenly sprinkled inside the processing cylinder 1. The outer surface of the circular cylinder 210 is also fixed with a second connecting plate 209. The rotational relationship between the second connecting plate 209 and the rotating shaft 202 can also provide a certain support force for the circular cylinder 210. Since the second connecting plate 209 and the rotating shaft 202 are rotatably connected, their operating states do not conflict. This effectively avoids the problem of slow medicine dissolution rate when the medicine is dispensed at too few points during use.
