Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a carbon source dosing device for wastewater treatment. Background Technology

[0002] Adding carbon sources during wastewater treatment can provide essential nutrients and energy for microorganisms in the wastewater, supporting reactions such as denitrification and phosphorus removal during the microbial treatment process.

[0003] Chinese utility model patent CN217732784U discloses a carbon source addition device for wastewater treatment, comprising a main unit and a feeding unit. The main unit includes a storage hopper with a connecting pipe fixedly connected to its bottom. A first sleeve is rotatably connected to the bottom of the connecting pipe, and a second sleeve is rotatably connected to the bottom of the first sleeve. The feeding unit includes a rotating shaft with multiple partitions fixedly connected to it. The first sleeve has multiple openings, and the second sleeve houses a dual-shaft motor. A worm gear is fixedly connected to the top output end of the dual-shaft motor. A rotating rod rotatably passes through the second sleeve, and a worm wheel is fixedly connected to the rotating rod, meshing with the worm gear. A transmission assembly connects the rotating rod to the rotating shaft.

[0004] The aforementioned utility model patent utilizes a dual-shaft motor to rotate a worm gear, which in turn rotates the first sleeve. Under centrifugal force, the material is thrown outwards through the opening, dispersing it into the wastewater and increasing the reaction rate. However, this utility model's technical solution is only applicable to wastewater tanks. When the wastewater tank is large, the carbon source addition and mixing rate is slow, reducing wastewater treatment efficiency. If the carbon source dosing device could be applied to wastewater treatment pipelines, carbon source dosing in wastewater treatment would be more convenient and efficient, and unaffected by the size of the wastewater treatment tank.

[0005] Based on this, the present invention provides a novel carbon source dosing device for wastewater treatment. Summary of the Invention

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a carbon source dosing device for sewage treatment, characterized in that it includes a pipe 1 for connecting to a sewage pipe, a fixed box 2 fixedly installed on the outer side of the middle position of the pipe 1, and a storage box 3 for storing carbon source installed on the top of the pipe 1 via a support rod 4. The fixed box 2 has an inner cavity 7. A rotating wheel 10 is rotatably installed inside the inner cavity 7, positioned above the pipe 1. A circular through hole 11 is opened on the inner wall of the pipe 1 corresponding to the inside of the inner cavity 7, and a diverter 12 is fixedly installed inside the pipe 1 at the position corresponding to the through hole 11. A delivery pump 8 is fixedly connected to the bottom end of the storage box 3, and a one-way valve 9 is fixedly connected to the bottom end of the delivery pump 8, with the one-way valve 9 fixedly connected to the inner cavity 7. By installing the pipe 1 between the sewage delivery pipeline, it is convenient to fully mix the liquid carbon source in the storage box 3 with the sewage, improving the mixing efficiency of the liquid carbon source and sewage, and demonstrating high practicality.

[0022] In this embodiment, flanges 6 are symmetrically fixed at both ends of the pipe 1, and support rods 4 are symmetrically fixed at the top of both ends of the pipe 1. The top of the support rods 4 is fixedly connected to the bottom sides of the storage tank 3, and the top of the storage tank 3 has an inlet 5. The flanges 6 facilitate fixing the two sides of the pipe 1, thus making it easy to connect the pipe 1 to the sewage pipe. The transfer pump 8 can draw liquid carbon source from inside the storage tank 3 and input it into the inner cavity 7, facilitating subsequent mixing of the liquid carbon source with sewage. The one-way valve 9 prevents sewage from flowing back into the storage tank 3.

[0023] In this embodiment, the rotating wheel 10 includes a rotating rod and blades. The blades are circular and fixedly mounted on the outer wall of the rotating rod. The rotating rod is rotatably mounted inside the inner cavity 7. A rubber pad is fixedly mounted at one end of the blade away from the rotating rod, and the rubber pad is in close contact with the inner wall of the inner cavity 7. A servo motor is fixedly mounted at the front end of the fixed box 2. The output shaft of the servo motor is fixedly connected to the front end of the rotating rod, and the servo motor can adjust the rotation of the rotating wheel 10. Under the action of the rotating wheel 10 and the inner cavity 7, the liquid carbon source inside the storage box 3 is drawn into the sewage. The rubber pad can improve the sealing between the blade and the inner wall of the inner cavity 7.

[0024] In this embodiment, the inside of the diversion frame 12 is provided with six diversion slots, such as... Figure 4As shown, there are six through holes 11, each connected to one of six diversion channels. A baffle 13 is fixedly installed on the inner wall of the pipe 1 on one side of the diversion frame 12, corresponding to the downstream direction of the water flow. The diversion channels of the diversion frame 12 facilitate the diversion of sewage in the pipe 1. After diversion, the six streams of sewage are simultaneously mixed with the liquid carbon source discharged into the six through holes 11 on the side of the pipe 1. Diversion can improve the mixing efficiency of liquid carbon source and sewage, and the baffle 13 can also block and divert sewage, facilitating the mixing of sewage.

[0025] The method of using the carbon source dosing device for sewage treatment provided by this utility model is as follows: Pipeline 1 is fixedly installed in the sewage conveying pipeline via flange 6. During the conveying process, sewage can enter the interior of pipe 1. Simultaneously, the conveying pump 8 is started, drawing liquid carbon source from the storage tank 3 and discharging it into the inner cavity 7 inside the fixed box 2 through one-way valve 9. At the same time, the servo motor is started, driving the blades to rotate inside the inner cavity 7 via a rotating rod to convey the liquid carbon source to pipe 1. The liquid carbon source mixes with the sewage in pipe 1 through the through hole 11. After the sewage flows into the diversion groove of the diversion frame 12, it is diverted, resulting in a more thorough mixing of the diverted sewage and liquid carbon source. A baffle 13 is installed to block and separate the mixture of sewage and carbon source, thereby improving the mixing efficiency of the liquid carbon source and sewage. The mixed liquid carbon source and sewage are then discharged into a sewage tank through the sewage pipeline for further treatment. The carbon source dosing device for sewage treatment provided by this utility model, when applied to sewage treatment pipelines, makes carbon source dosing in sewage treatment more convenient and efficient, and is not affected by the size of the sewage treatment tank. Compared to existing carbon source dosing devices, its efficiency has been greatly improved.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
