[0002] As is well known, wastewater treatment ponds are a core component of wastewater treatment systems, primarily used for collecting, storing, and treating industrial or domestic wastewater. The wastewater treatment process requires the use of treatment chemicals to accelerate treatment efficiency, which necessitates the use of dosing devices to input the chemicals.

[0003] A utility model patent with patent authorization announcement number CN214399863U discloses a dosing device for wastewater treatment, including a stirring tank and a grinding tank. The stirring tank is equipped with a stirring assembly, which includes a stirring support, a stirring motor, a stirring shaft, and a stirring paddle. The grinding tank is equipped with a grinding assembly, which includes a grinding support, a grinding motor, a grinding shaft, a grinding disc, and a grinding base. The grinding support is installed on the top of the grinding tank, the grinding motor is installed on the grinding support, the grinding shaft is rotatably connected to the grinding support and connected to the grinding motor, the lower part of the grinding shaft extends into the grinding tank and is connected to the grinding disc, and the grinding base is installed on the inner bottom wall of the grinding tank. The bottom surface of the grinding disc and the top surface of the grinding base are both conical, and the cone angle of the bottom surface of the grinding disc is smaller than the cone angle of the top surface of the grinding base. The grinding base is also provided with a discharge port that communicates with the discharge port.

[0004] However, existing wastewater treatment tank dosing devices also have certain shortcomings. Most existing wastewater treatment tank dosing devices use a fixed-position discharge port to input the treatment agent. Due to the fixed discharge angle and the limited flow of wastewater inside the tank, the dosing efficiency is easily poor. Utility Model Content

[0005] The purpose of this utility model is to provide a dosing device for wastewater treatment ponds, which solves the problem that existing dosing devices for wastewater treatment ponds mostly use a fixed-position discharge port to input the treatment agent. Due to the fixed discharge angle and the limited flow of wastewater inside the pond, the dosing efficiency is poor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment tank dosing device, comprising a wastewater tank, a drain pipe fixedly connected to the inner wall of the wastewater tank, a support plate fixedly connected to the upper end of the wastewater tank, a rotating pipe mounted on the inner wall of the support plate via a bearing, a spray pipe fixedly connected to the surface of the rotating pipe, a nozzle fixedly connected to the surface of the spray pipe, a support ear fixedly connected to the upper end of the support plate, an input pipe fixedly connected to the inner wall of the support ear, a vertical part of the input pipe rotatably connected to the rotating pipe, a large gear fixedly sleeved on the outer side of the rotating pipe, and an auxiliary mechanism provided on the support plate.

A limiting plate is fixedly connected to the end face of the support rod. The limiting plate contacts the rotating pipe. Through the cooperation of the waterproof motor, the large gear, and other structures, the rotating pipe can be driven to rotate, thereby driving the nozzle to rotate and rotating the treatment agent for use.

[0008] Preferably, two limiting plates are provided, and the two limiting plates are symmetrically distributed on the rotating tube. The limiting plates can guide the rotation of the rotating tube.

[0009] Preferably, the auxiliary mechanism includes a mounting frame, with the upper end of the support plate fixedly connected to the mounting frame. An oil reservoir is fixedly connected to the inner wall of the mounting frame, and an end rod is slidably connected to the inner wall of the oil reservoir. The end rod is slidably connected to the mounting frame, and a plug is fixedly connected to the lower side of the end rod. The plug is slidably connected to the oil reservoir. A connecting plate is fixedly sleeved on the outer side of the end rod, and a spring is provided on the outer side of the end rod. By pulling the end rod, the plug is moved, causing it to disengage from the flow hole on the surface of the oil reservoir, thereby allowing the lubricating oil to flow through.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the setting of a conveying pipe, a rotating pipe, a nozzle, and other structures, can add treatment agents into the wastewater pool. With the waterproof motor, large gear, and other structures, the rotating pipe can drive the nozzle to rotate, thereby improving the dosing effect of the agent. With the limiting plate, elastic block, and other structures, the rotating pipe can be auxiliaryly limited to ensure good stability of the rotating pipe rotation.

[0015] 2.

The vertical part of the input pipe 8 is rotatably connected to the rotating pipe 4. A large gear 9 is fixedly sleeved on the outer side of the rotating pipe 4.

[0023] Please see Figure 1 , Figure 2 , Figure 3 A waterproof motor 10 is fixedly installed at the lower end of the support plate 3. The output shaft of the waterproof motor 10 is rotatably connected to the support plate 3. A small gear 11 is fixedly sleeved on the outside of the output shaft of the waterproof motor 10. The small gear 11 meshes with the large gear 9. An elastic block 12 is bonded to the inner wall of the wastewater tank 1. A support rod 13 is bonded to the end face of the elastic block 12. A limiting piece 14 is fixedly connected to the end face of the support rod 13. The limiting piece 14 contacts the rotating tube 4. There are two limiting pieces 14, which are symmetrically distributed on the rotating tube 4. The limiting pieces 14 can guide the rotation of the rotating tube 4. Through the cooperation of the waterproof motor 10, the large gear 9 and other structures, the rotating tube 4 can be driven to rotate, thereby driving the nozzle 6 to rotate and input the treatment agent.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 An auxiliary mechanism 15 is provided on the support plate 3. The auxiliary mechanism 15 includes a mounting frame 151. The mounting frame 151 is fixedly connected to the upper end of the support plate 3. An oil storage box 152 is fixedly connected to the inner side wall of the mounting frame 151. An end rod 153 is slidably connected to the inner wall of the oil storage box 152. The end rod 153 is slidably connected to the mounting frame 151. A plug 154 is fixedly connected to the lower side of the end rod 153. The plug 154 is slidably connected to the oil storage box 152. A connecting plate 155 is fixedly sleeved on the outer side of the end rod 153. A spring 156 is provided on the outer side of the end rod 153. By pulling the end rod 153, the plug 154 is moved, so that the plug 154 is disengaged from the flow hole opened on the surface of the oil storage box 152, thereby allowing the lubricating oil to be used.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4One end of the spring 156 is welded to the mounting bracket 151, and the other end of the spring 156 is welded to the connecting plate 155.

With the cooperation of the spray pipe 5 and the nozzle 6, the treatment agent can be sprayed. The waterproof motor 10 is started to drive the output shaft to rotate, so as to drive the small gear 11 to rotate. Under the meshing relationship, the small gear 11 drives the large gear 9 to rotate, so as to drive the rotating pipe 4 to rotate, and then drive the spray pipe 5 and the nozzle 6 to rotate, so as to dynamically spray the treatment agent, improve the dosing efficiency of the treatment agent. When the rotating pipe 4 rotates, the limiting piece 14 can slide along the surface of the rotating pipe 4, and with the deformation of the elastic block 12, the rotating pipe 4 can be guided to rotate, so as to ensure the stable effect of the rotation of the rotating pipe 4.

[0027] By pulling end 157 to the right, end rod 153 is moved, which in turn moves connecting plate 155, causing spring 156 to deform. When end rod 153 moves, it can move plug 154, which eventually disengages from the flow hole of oil reservoir 152, allowing lubricating oil to flow through and come into contact with large gear 9 and small gear 11, thus lubricating the gears and reducing hard wear between them.
