Description

Technical Field

[0001] This application relates to the field of wastewater treatment, and more specifically, to a high-efficiency, low-cost composite carbon source reagent mixing device for wastewater treatment. Background Technology

[0002] In the treatment of industrial wastewater and domestic sewage, the efficiency and effectiveness of nitrogen and phosphorus removal are often important factors considered by sewage treatment plants. However, in the biological treatment stage, insufficient carbon source can lead to a lack of heterotrophic bacteria to multiply rapidly, resulting in a significant reduction in nitrogen removal efficiency and a failure to effectively reduce total nitrogen content after biological treatment. To improve nitrogen removal efficiency and promote the proliferation of heterotrophic bacteria, sewage treatment plants often add carbon sources during the denitrification stage of biological treatment. Carbon sources are divided into two main categories: single carbon sources and composite carbon sources. Single carbon sources are often insufficient to achieve the desired effect, so sewage treatment plants often use composite carbon sources to supplement the carbon source in the denitrification stage. To effectively improve the mixing of composite carbon sources with wastewater, mixing devices are often used.

[0003] Patent document CN215388905U discloses a composite carbon source reagent mixing device for wastewater treatment. This utility model relates to the field of wastewater treatment technology, and particularly to a composite carbon source reagent mixing device for wastewater treatment. It includes a housing with two shafts rotatably connected inside. Multiple stirring rods are fixedly connected to the shafts. A driving mechanism is provided on the top surface of the housing. A transparent measuring cylinder with graduations is installed on the top surface of the housing. A connecting pipe is installed on the bottom surface of the transparent measuring cylinder, with its lower end penetrating the top surface of the housing and extending into the housing. A first valve is installed on the connecting pipe. An outlet pipe is installed on the bottom surface of the housing. The aforementioned application describes mixing by rotating the stirring rods on the two shafts inside the housing. However, when the two shafts rotate, the circular range of rotation of the stirring rods cannot completely cover the inner surface of the housing, like two small circles inside a large circle. There are areas that the stirring rods cannot reach during mixing, hindering efficient mixing. Utility Model Content

Detailed Implementation

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example 1

[0022] See Figure 1-Figure 4This embodiment provides a high-efficiency, low-cost composite carbon source reagent mixing device for wastewater treatment, including a tank 1. A stirring assembly 2 is disposed on the inner surface of the tank 1. The stirring assembly 2 includes a support base 201, which is fixedly connected to the top of the tank 1. A motor 202 is fixedly connected to the left side of the support base 201, with the output end of the motor 202 facing downwards. A rotating shaft 203 is fixedly connected to the output end of the motor 202 via a coupling. The rotating shaft 203 passes through and is rotatably connected to the top of the tank 1. A bearing is disposed between the rotating shaft 203 and the tank 1. A rotating rod 204 passes through and is rotatably connected to the left side of the rotating shaft 203. A bearing is disposed between the rotating rod 204 and the rotating shaft 203. 4. Four stirring plates 205 are fixedly connected to the upper and lower surfaces. A bevel gear 206 is fixedly connected to the outer surface of the rotating rod 204. A crown gear 207 meshes with the bevel gear 206 below. The crown gear 207 has a hole in the middle, and the rotating shaft 203 is set in the hole. A support rod 208 is fixedly connected to the lower part of the crown gear 207. The support rod 208 is fixedly connected to the bottom of the inner surface of the tank 1. The stirring assembly 2 also includes a stirring rod 209, which is fixedly connected to the outer surface of the rotating shaft 203. A first feed port 3 and a second feed port 4 are fixedly connected to the upper part of the tank 1. The first feed port 3 and the second feed port 4 are respectively used to transport wastewater and composite carbon source agent into the tank 1.

[0023] In practical use, the above-mentioned equipment first feeds wastewater and composite carbon source agent into tank 1 through the first feed port 3 and the second feed port 4, respectively. Then, the motor 202 is started, which drives the rotating shaft 203 to rotate, causing the stirring rod 209 to rotate, thereby stirring the wastewater and composite carbon source agent. When the rotating shaft 203 rotates, it also drives the rotating rod 204 to rotate around the rotating shaft 203. At this time, the bevel gear 206 on the rotating rod 204 will roll on the crown gear 207. The bevel gear 206 will be pushed by the crown gear 207, thereby driving the rotating rod 204 to rotate on its own axis while rotating around the rotating shaft 203. At this time, the rotation of the rotating rod 204 will drive the stirring plate 205 to rotate, thereby improving the mixing effect. Example 2

[0024] See Figure 1-Figure 4Based on Embodiment 1, a drainage assembly 5 is provided below the tank body 1. The drainage assembly 5 includes four support legs 501, which are fixedly connected to the bottom of the tank body 1. A drain valve 502 is fixedly connected to the bottom of the tank body 1. A protective assembly 6 is provided on the inner surface of the tank body 1. The protective assembly 6 includes a protective shell 601, which is hollow and fixedly connected to the outer surface of the rotating shaft 203. The rotation of the rotating shaft 203 can drive the protective shell 601 to rotate. The protective shell 601 and the rotating rod 20 4. The outer surface is slidably connected. The protective shell 601 is provided with a through hole for accommodating the rotating rod 204. The protective shell 601 is slidably connected to the bottom of the inner surface of the tank 1. The bottom of the inner surface of the tank 1 is provided with an annular groove for the sliding of the protective shell 601. The protective component 6 also includes a water supply pipe 602. The water supply pipe 602 is fixedly connected to the bottom of the tank 1 and fixedly connected to the right side of the drain valve 502. The water supply pipe 602 and the drain valve 502 are connected. The connection point between the water supply pipe 602 and the drain valve 502 is located below the valve core of the drain valve 502.

[0025] When the rotating shaft 203 rotates, it will also drive the protective shell 601 to rotate. The protective shell 601 will slide in the annular groove at the bottom of the inner surface of the tank 1. The protective shell 601 will protect the bevel gear 206 and crown gear 207 to prevent wastewater from entering and affecting the meshing effect. When wastewater leaks into the protective shell 601, the wastewater will accumulate at the bottom of the inner surface of the tank 1 inside the protective shell 601. At this time, the wastewater will be discharged to the drain valve 502 through the water supply pipe 602 to clean up the wastewater leaking into the protective shell 601.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
