Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, and in particular to an aeration and dosing component and a wastewater treatment device. Background Technology

[0002] In wastewater treatment, it is often necessary to add chemicals to the reaction tank. Chemical addition requires a dosing pump to pump the chemical solution into the reaction tank. At the same time, in order to make the chemicals more thoroughly mixed, a stirring device is added to the reaction tank. The stirring device can be mechanical stirring or aeration stirring. Aeration stirring often requires aeration devices such as blowers and aeration pipelines. It can be seen that when doing chemical addition, multiple devices need to work together, resulting in many devices and high investment costs. Utility Model Content

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figure 2 As shown, the present invention provides a first embodiment, which provides an aeration and dosing component 2, including a first pipe, a second pipe connected to the first pipe, and a nozzle structure disposed between the first pipe and the second pipe;

[0027] Among them, such as Figure 2 As shown, the first pipe includes an input pipe 21 and an output pipe 22 disposed on the input pipe 21. The input pipe 21 is vertical and forms an inlet chamber 24 inside. Both ends are open, and the opening at the bottom is the inlet 23.

[0028] In this embodiment, there are two output pipes 22, located on both sides of the upper part of the input pipe 21. The two output pipes 22 are inclined towards the outside of the input pipe 21 and are fixedly connected to the input pipe 21. An output cavity 26 is formed inside the output pipe 22. The two output pipes 22 and the input pipe 21 are combined to form a Y shape. The output cavity 26 of the output pipe 22 is connected to the water inlet cavity 24 of the input pipe 21. Sewage flows into the input pipe 21 and flows out from the output pipe 22. Furthermore, the number of output pipes 22 can be increased or decreased according to the actual situation, and no limitation is made here.

[0029] The second pipe includes an air inlet pipe 27 and a drug inlet pipe 210 installed on the air inlet pipe 27. Air enters into the air inlet pipe 27 and mixes thoroughly with water in the channel through which it flows before being sprayed out from the output pipe 22 together with the water to achieve the aeration effect.

[0030] The air inlet pipe 27 is vertical with open ends. The lower end is fixedly connected to the first pipe, and the upper opening forms an air inlet 28, which connects to the air inlet pipe 27 to introduce air into the aeration and dosing assembly 2. An air inlet chamber 29 is formed inside the air inlet pipe 27. The air inlet chamber 29 of the air inlet pipe 27, the output chamber 26 of the output pipe 22, and the water inlet chamber 24 of the input pipe 21 are interconnected. A confluence chamber 25 is formed at the intersection of the air inlet chamber 29 of the air inlet pipe 27, the output chamber 26 of the output pipe 22, and the water inlet chamber 24 of the input pipe 21. A nozzle structure is located in the confluence chamber 25.

[0031] The inlet pipe 210 is fixedly connected to the side wall of the air inlet pipe 27. The inlet pipe 210 forms an inlet chamber 212 inside and is open at both ends. The inlet end of the inlet pipe 210 away from the air inlet pipe 27 forms an inlet port 211, which is connected to the inlet connecting pipe 6. The liquid medicine is introduced into the aeration and dosing assembly 2 through this connection. The inlet chamber 212 of the inlet pipe 210 is connected to the air inlet chamber 29 of the air inlet pipe 27. The liquid medicine flows from the inlet pipe 210 into the air inlet pipe 27 and flows out from the outlet pipe 22. Furthermore, the inlet pipe 21, the outlet pipe 22, the air inlet pipe 27 and the inlet pipe 210 are integrally formed.

[0032] The nozzle structure includes a top wall 213 and a side wall 214. The top wall 213 has a V-shaped longitudinal section, and the side wall 214 has a trumpet-shaped longitudinal section. The top wall 213 and the side wall 214 are integrally formed. The bottom end of the side wall 214 is sealed and fixedly connected to the upper part of the input pipe 21. The nozzle structure is located at the confluence chamber 25. The center of the input pipe 21 and the nozzle structure are on the same straight line. Two injection chambers 218 with gradually decreasing cross-sectional areas are formed between the top wall 213 and the side wall 214. That is, the injection chambers 218 are trumpet-shaped. The ends of the injection chambers 218 form nozzles 215. The injection chambers 218 are connected to the output chamber 26 of the output pipe 22 through the nozzles 215, and the injection direction of the nozzles 215 is... Parallel to the centerline of the output pipe 22, since the diameter of the nozzle 215 is much smaller than that of the input pipe 21, according to Bernoulli's equation, the rapid reduction of the flow cross-section will create a high-speed water flow that is sprayed into the output pipe 21 at the nozzle 215, thereby creating a negative pressure zone around the high-speed water flow. Furthermore, the nozzle structure is also provided with two extension pipes 217, which are located at the two nozzles 215. The two extension pipes 217 are integrally formed with the nozzle structure, and the inner cavity of the extension pipe 217 is on the same axis as the nozzle 215. By setting the extension pipes 217, the water flow can be sprayed more concentratedly into the output pipe 22 from the nozzle 215 through the inner cavity of the extension pipe 217.

[0033] In summary, wastewater is pumped into the input pipe 21 by the inlet pump 4, and then enters the output pipe 22 through the nozzle 215. Due to the design of the nozzle 215, the flow velocity of the wastewater entering the output pipe 22 can reach 10m / s-20m / s. The high-speed spraying of wastewater from the nozzle 215 creates a low-pressure zone in the area connected to the nozzle 215, causing the chemical solution and air to be drawn into the aeration and dosing component 2. Furthermore, due to the high kinetic energy of the high-speed jet of wastewater from the nozzle 215, a turbulent effect is created, which can fully mix the drawn-in air and the chemical before entering the reaction tank 1 through the output pipe 22. The water sprayed from the nozzle 215 contains a large number of air bubbles, which fully agitate the water in the reaction tank 1 as they rise.

[0034] like Figure 2 As shown, the present invention also provides a second embodiment, which further includes a drug mixer 216 disposed in the air intake pipe 27 based on the first embodiment.

[0035] Among them, the chemical mixer 216 is a commercially available static mixer. The highest end of the chemical mixer 216 is located below the inlet pipe 210. The chemical mixer 216 is used to mix the chemical air in the aeration dosing assembly 2 with the sewage.

[0036] like Figure 1As shown, this utility model also provides a third embodiment, which provides a sewage treatment device. The sewage treatment device includes a reaction tank 1, an aeration and dosing component 2 of embodiment one or embodiment two is installed in the reaction tank 1, and the aeration and dosing component 2 is immersed in the liquid of the reaction tank 1; the inlet 23 of the input pipe 21 is connected to the output end of the water pump 4 through the water inlet connecting pipe 3, the input end of the water pump 4 is connected to the sewage storage container through the sewage connecting pipe 5, the air inlet 28 of the air inlet pipe 27 is connected to one end of the air inlet connecting pipe 8, and the other end of the air inlet connecting pipe 8 extends out of the liquid in the reaction tank 1 and is exposed to the air, and the inlet 211 of the dosing pipe 210 is connected to the dosing tank through the dosing connecting pipe 6.

[0037] It is understood that when water pump 4 is started, it pumps the sewage from the sewage storage container into the aeration and dosing assembly 2. As the sewage is pumped into the aeration and dosing assembly 2, suction is generated at the nozzle 215, drawing air into the assembly 2 through the air inlet connection pipe 8, achieving natural aeration. Alternatively, in other embodiments, the end of the air inlet connection pipe 8 exposed to air can be connected to an air guide, which guides air into the aeration and dosing assembly 2. The air guide can be a blower or air compressor. The suction generated at the nozzle 215 allows the chemical solution in the chemical tank to be drawn into the aeration and dosing assembly 2 through the dosing connection pipe 6. Thus, the sewage, chemical solution, and air are mixed in the aeration and dosing assembly 2 before being sprayed into the reaction tank 1.

[0038] Furthermore, a first control component 7 is provided on the drug inlet connecting pipe 6, and a second control component 9 is provided on the air inlet connecting pipe 8. The first control component 7 is used to control the flow rate of the drug inlet, and the second control component 9 is used to control the flow rate of the air inlet.

[0039] The first control component 7 includes a flow control valve, a check valve, and a flow meter. The flow control valve can be used to close or open the dosing channel. The flow meter can be used to view the current dosing amount. The flow control valve and flow meter can be used to control the dosing amount. The check valve can be used to prevent liquid from flowing back into the chemical tank.

[0040] The second control component 9 includes a valve and a flow meter. The valve can be used to close or open the air intake passage, and the flow meter can be used to view the current air intake flow rate. The valve and flow meter can be used to control the air flow rate.

[0041] In summary, the negative pressure suction generated by the sewage jet draws the agent into the aeration dosing component 2 through the inlet pipe 210, eliminating the need for a dosing pump. Furthermore, the negative pressure suction generated by the sewage jet can also draw a certain amount of air into the aeration dosing component 2, which requires less air pressure than conventional blower aeration devices, thus reducing energy consumption and equipment costs. This eliminates the need for dosing pumps, mixing devices, and aeration devices in traditional dosing equipment, saving costs.
