[0002] Smart rural environmental governance is an important component of rural digital transformation and the rural revitalization strategy. It utilizes modern information technologies, such as the internet, big data, cloud computing, and the Internet of Things, to intelligently manage and serve all aspects of rural production, life, and ecology, thereby improving the efficiency and quality of rural governance and achieving sustainable development of the rural economy, society, and environment. Smart rural environmental governance mainly includes intelligent agriculture, intelligent logistics and agricultural product sales, rural life services and community building, environmental protection, and sustainable agricultural development models.

[0003] Environmental protection is a crucial component of wastewater treatment in rural areas. This involves regularly adding appropriate amounts of chemicals to the wastewater treatment pipelines. The chemicals react with pollutants in the wastewater to purify it. However, existing wastewater treatment pipelines often use a buried dosing pipe connected to the main wastewater treatment pipeline. The chemicals are then added to the wastewater through this pipe. However, once the chemicals enter the main pipeline, they only mix with the wastewater near the dosing pipe, resulting in the wastewater in other areas only mixing with a small amount of chemicals or not mixing at all. This prevents a large amount of wastewater from reacting with the chemicals, reducing the effectiveness of wastewater treatment. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater harmless treatment device that allows the reagents to be mixed more evenly with the wastewater, thereby improving the wastewater treatment effect.

[0005] The aforementioned wastewater harmless treatment device includes a horizontally arranged outer pipe, inside which a vertically arranged arc-shaped guide plate is installed, with the arc surface of the guide plate facing the water inlet end of the outer pipe. An installation groove is formed at the center of the arc surface of the guide plate, and a truncated cone with its tip facing the water inlet end of the outer pipe is fixed in the installation groove. A water delivery pipe is installed on the outer pipe, with one end of the water delivery pipe aligned with the truncated cone. A drug delivery component for delivering the drug to the water delivery pipe is installed on the outer pipe. Several guide grooves communicating with the installation groove are formed on the arc surface of the guide plate. A stirring component for stirring and mixing the wastewater containing the drug is installed inside the outer pipe.

[0006] Furthermore, the drug delivery assembly includes a drug storage tank, which is installed on the outer wall of the outer tube. A water pump is installed on the outer wall of the outer tube. The inlet of the water pump is connected to the inside of the drug storage tank, and the outlet of the water pump is connected to the end of the water delivery pipe located outside the outer tube. A check valve is installed on the water delivery pipe.

[0007] Furthermore, the stirring assembly includes a circular tube, which is horizontally located inside the outer tube. Support rings are fixed between the two ends of the circular tube and the inner wall of the outer tube. Several spiral guide plates for guiding sewage to flow in a spiral pattern are fixed on the inner wall of the circular tube.

[0008] Furthermore, the support ring is funnel-shaped.

[0009] Furthermore, the circular tube is connected to the drug guide plate by several connecting rods.

[0010] Furthermore, the drug guiding channel includes several long drug guiding channels and several short drug guiding channels. All the long drug guiding channels are evenly distributed along the circumference of the drug guiding plate and are used to guide the drug to the surrounding areas. All the short drug guiding channels are evenly distributed along the circumference of the drug guiding plate, and each short drug guiding channel has a passing hole on its bottom for the drug to pass through. Furthermore, both ends of the outer tube are provided with flanges, and several through holes are provided on the flanges.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The agent is delivered to the water supply pipe via the delivery unit, then to the outer pipe, and discharged towards the truncated cone. The truncated cone divides the agent from the center, allowing it to flow and disperse evenly outwards along its conical surface and into the installation tank. As the wastewater flows, it carries the agent along the nearest guide channel, dispersing it to various areas within the outer pipe and improving the mixing effect between the agent and wastewater.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0019] Example

[0020] The wastewater harmless treatment device described in this embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, it includes a horizontally arranged outer pipe 7, with flanges at both ends of the outer pipe 7. Several through holes are provided on the flanges, and the through holes on the flanges are used to install bolts. The outer pipe 7 is connected to the sewage treatment pipe by bolts, so that the sewage in the sewage treatment pipe can flow through the outer pipe 7.

[0021] The outer pipe 7 is vertically provided with a guide plate 9 in the shape of an arc, with the arc surface of the guide plate 9 facing the water inlet end of the outer pipe 7. In use, after the sewage enters the outer pipe 7, the guide plate 9 changes the flow direction of the sewage through the characteristics of its arc structure, so that the sewage flows into the rear half of the outer pipe 7 through the gaps around the guide plate 9 along the outer circular surface of the guide plate 9.

[0022] A mounting groove is provided at the center of the arc surface of the guide plate 9. A truncated cone 11 with its tip facing the water inlet end of the outer pipe 7 is fixed in the mounting groove. A water delivery pipe 1 is threaded through the outer pipe 7, with one end of the water delivery pipe 1 aligned with the truncated cone 11. In this embodiment, the water delivery pipe 1 is a rigid pipe made of metal or rigid plastic, making it less prone to deformation or swaying during use. The water delivery pipe 1 is used to transport liquid agents in sewage, such as... Figure 1 As shown, when the medicine flows out of the water pipe 1, the truncated cone 11 can divide the medicine from the center, allowing the medicine to flow and disperse evenly in all directions along the conical surface of the truncated cone 11 and enter the installation groove.

[0023] To elaborate further, such as Figure 1 and Figure 3As shown, this embodiment preferably includes a medicine storage tank 3, which is installed on the outer wall of the outer pipe 7. During use, medicine can be added from the opening of the storage tank 3 and sealed with a lid. A water pump 2 is installed on the outer wall of the outer pipe 7. The inlet of the water pump 2 is connected to the inside of the storage tank 3, and the outlet of the water pump 2 is connected to the end of the water delivery pipe 1 located outside the outer pipe 7. The water pump 2 can be electrically connected to a control terminal, which controls the opening and closing of the water pump 2 to remotely control the amount of medicine added. When the water pump 2 is turned on, it draws the medicine from the storage tank 3, pressurizes it, and delivers it to the water delivery pipe 1, which then delivers it to the outer pipe 7. A check valve is installed on the water delivery pipe 1. A check valve is a type of valve whose opening and closing element is a circular valve disc that relies on its own weight and the pressure of the medium to prevent backflow of the medium. This is an existing product. Figure 1 As shown, a check valve is connected to the middle section of the water supply pipe 1 to prevent the medicine or sewage in the outer pipe 7 from flowing back into the storage tank 3; the whole solution constitutes a medicine delivery assembly for delivering medicine to the water supply pipe 1.

[0024] The guide plate 9 has several guide grooves communicating with the installation groove on its arc surface. These guide grooves include several long guide grooves 12 and several short guide grooves 13. All long guide grooves 12 are evenly distributed along the circumference of the guide plate 9 and are used to guide the medicine to the surrounding area. All short guide grooves 13 are evenly distributed along the circumference of the guide plate 9, and each short guide groove 13 has a passage hole 10 on its bottom for the medicine to pass through. When the medicine flows into the installation groove, it will flow along the nearest guide groove under the influence of the sewage flow, such as... Figure 2 and Figure 4 As shown, the agent in the long guide channel 12 is guided to the outside of the guide plate 9. Through all the long guide channels 12, part of the agent is guided to the periphery of the guide plate 9, where it mixes with the surrounding sewage and continues to flow into the rear half of the outer pipe 7. When the agent in the short guide channel 13 flows to the end, it passes through the end through the medicine hole 10 and mixes with the sewage in the center area of ​​the inner side of the outer pipe 7. Through the above process, the agent is guided to each area in the outer pipe 7, thereby improving the mixing effect of the agent and the sewage.

[0025] To elaborate further, such as Figure 1 and Figure 3 As shown, this embodiment preferably includes a circular tube 5, which is horizontally located inside the outer tube 7. Support rings 4 are fixed between both ends of the circular tube 5 and the inner wall of the outer tube 7. The support rings 4 are funnel-shaped, guiding water from the outer tube 7 into the circular tube 5. The support rings 4 support the circular tube 5, positioning it at the center of the outer tube 7. In this embodiment, the support rings 4 are fixed inside the outer tube 7 with screws. Several connecting rods 8 connect the circular tube 5 to the guide plate 9, such as... Figure 1As shown, the support ring 4 is connected to the guide plate 9 by several connecting rods 8. The guide plate 9 is supported and positioned by the connecting rods 8. When the support ring 4 is disassembled, the guide plate 9 can be disassembled at the same time. Several spiral guide plates 6 are fixed on the inner wall of the circular pipe 5 to guide the sewage to flow in a spiral pattern. Figure 1 and Figure 4 As shown, in this embodiment, four sets of spiral guide plates 6 are used, and the four sets of spiral guide plates 6 are evenly distributed along the circumference. When the sewage mixed with the agent enters the circular pipe 5, the four sets of spiral guide plates 6 will guide the sewage flow in a spiral shape. When the sewage flows in a spiral shape, it can increase the eddies and turbulence in the fluid, thereby increasing the collision and mixing opportunities between the agent and water molecules, improving the mixing effect between the agent and the sewage, and allowing the agent and sewage to be mixed evenly, so that the pollutants and agents can react fully. This solution constitutes a stirring assembly for stirring and mixing sewage containing the agent. Of course, the stirring assembly can also be a propeller. A mounting rod is vertically installed inside the circular pipe 5, and the propeller is rotatably fixed on the mounting rod. When the sewage passes through the propeller, it will push the propeller to rotate. During the rotation, the sewage flow will be disturbed, thereby making the agent and sewage mix more evenly. In actual use, the outer pipe 7 is connected to the sewage treatment pipeline. When chemicals need to be added, the water pump 2 is turned on. The water pump 2 draws the chemicals from the storage tank 3. After being pressurized by the water pump 2, the chemicals are transported to the water supply pipe 1 and then to the outer pipe 7. The chemicals are then discharged towards the truncated cone 11. The truncated cone 11 divides the chemicals from the center, allowing them to flow and disperse relatively evenly around the cone surface of the truncated cone 11 and enter the installation groove. During the flow of sewage, the chemicals will be carried along the guide groove in the nearest direction, thereby dispersing the chemicals to various areas within the outer pipe 7 and improving the mixing effect between the chemicals and sewage. Afterward, the sewage mixed with chemicals will flow into the circular pipe 5. The spiral guide plate 6 guides the sewage flow in a spiral shape, allowing the chemicals and sewage to mix evenly and improving the mixing effect between the chemicals and sewage, so that the pollutants and chemicals can react fully.
