Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a gravity siphon type environmentally friendly dosing device. Background Technology

[0002] In the field of environmental dosing equipment technology, current dosing devices mostly use electric pumps and mechanical agitators to add chemicals. The performance of the dosing device plays a crucial role in the field of environmental protection equipment technology. While electric pumps and mechanical agitators can be used in some large-scale wastewater treatment plants, they are insufficient for the needs of smaller wastewater treatment scenarios.

[0003] Currently, small-scale wastewater treatment plants, such as small community wastewater treatment plants, typically have limited budgets. Traditional dosing systems often have complex components, leading to high costs. The operation of these dosing systems usually consumes a large amount of electricity, placing a financial burden on small community wastewater treatment plants beyond their means. The annual maintenance and repair costs for these dosing systems are also high, easily creating a significant economic burden. Furthermore, traditional dosing equipment does not conform to green environmental protection principles, as its continuous reliance on electrically powered dosing systems increases carbon emissions to some extent. Utility Model Content

[0010] A sealing ring is fitted to the inner wall of the through hole, and the sealing ring abuts against the side wall of the siphon tube.

[0011] A conical plate is fixedly connected to the bottom of the partition between the sewage pipe and the transfer pipe.

[0012] The siphon tube is fitted with a throttling valve on its side wall.

[0013] The medicine container has a medicine adding hole on its top surface, and a sealing cap is threaded into the medicine adding hole. A handle is fixedly connected to the top surface of the sealing cap.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-3As shown, the gravity siphon type environmental protection dosing device includes a pretreatment water tank 1 and a chemical tank 2. Two supports 3 are fixedly connected to the side wall of the chemical tank 2. The other end of the supports 3 is fixedly connected to the end face of the pretreatment water tank 1. A partition 4 is fixedly connected to the inner wall of the chemical tank 2. The upper side of the partition 4 is the chemical chamber, and the lower side of the partition 4 is the mixing chamber.

[0024] The side wall of the medicine tank 2 is fixedly connected to a sewage pipe 9 and a transfer pipe 8. Both the sewage pipe 9 and the transfer pipe 8 are connected to the mixing chamber. The top surface of the medicine tank 2 is provided with a through hole 6. A siphon pipe 5 is installed in the through hole 6. One end of the siphon pipe 5 is inserted into the transfer pipe 8, and the other end extends to the bottom of the medicine chamber.

[0025] The bottom of the medicine container 2 is conical, and a guide pipe 10 is fixedly connected to the bottom of the medicine container 2.

[0026] like Figure 2 As shown, a spiral baffle 11 is rotatably connected to the inner cavity of the guide pipe 10, and a scattering nozzle 12 is fixedly connected to the bottom of the guide pipe 10. The agent flows into the mixing chamber through the siphon pipe 5, and is quickly dispersed into the water body by the action of the scattering nozzle 12 and the spiral baffle 11, thereby achieving rapid and uniform mixing of the agent and the sewage.

[0027] The agent can be a flocculant, coagulant, oxidant, or defoamer, or other agents.

[0028] like Figure 3 As shown, a sealing ring 7 is fitted to the inner wall of the through hole 6, and the sealing ring 7 abuts against the side wall of the siphon tube 5. When the siphon tube 5 is inserted into the medicine container 2, the elasticity of the sealing ring 7 allows it to fit tightly against the siphon tube 5, keeping the medicine container 2 sealed and preventing leakage or evaporation of the medicine. In addition, the siphon tube 5 is made of transparent food-grade silicone tubing, and the increased friction between the two after abutting against the sealing ring 7 also provides support and fixation for the siphon tube 5.

[0029] like Figure 2 As shown, a conical plate 13 is fixedly connected to the bottom surface of the partition plate 4 between the sewage pipe 9 and the transfer pipe 8. The conical plate 13 facilitates the interaction between sewage and chemicals along the arc surface of the conical plate 13 for initial mixing. On the other hand, it prevents excessive impact force when sewage is discharged, which could easily cause backflow or stagnation of chemicals, thus buffering and shielding the impact of sewage.

[0030] like Figure 2 As shown, a throttle valve 14 is installed on the side wall of the siphon pipe 5. The throttle valve 14 is rotated according to the treatment requirements to adjust the chemical flow rate, meeting the dosing needs of wastewater with different flow rates and pollution levels.

[0031] like Figure 1 and Figure 2As shown, the top surface of the medicine container 2 has a medicine adding hole, and a sealing cap 15 is threaded into the medicine adding hole. A handle is fixedly connected to the top surface of the sealing cap 15. The medicine container 2 is made of transparent material, and scale lines 16 are provided on the side wall of the medicine container 2.

[0032] The medicine container 2 can be made of acrylic, glass or other materials, which makes it convenient for staff to observe the use of the medicine inside. The remaining amount of medicine can be accurately observed and recorded through the scale line 16. When medicine needs to be added, the staff can turn off the sealing cap 15 and add medicine directly through the filling hole. The structure is simple and the operation is convenient.

[0033] The working principle of this utility model is as follows: First, negative pressure is formed by pre-evacuation, and the liquid level difference is used to drive the flow of the agent. Then, one end of the siphon pipe 5 is inserted into the transfer pipe 8, so that the agent enters the mixing chamber through the transfer pipe 8. At the same time, the sewage is discharged from the sewage pipe 9 into the mixing chamber by external equipment. The agent and sewage impact the conical plate 13 for the first mixing.

[0034] When the agent and wastewater enter the guide pipe 10, they can be mixed a second time using the spiral baffle 11 to increase the mixing rate between the wastewater and the agent. The mixed wastewater is then discharged into the pretreatment tank 1 through the scattering nozzle 12, thus achieving the purpose of non-powered dosing.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
