Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water and sewage treatment, and particularly relates to a multi-purpose aeration head capable of aeration and medicine adding. BACKGROUND

[0002] In a water treatment system, some processes use aeration equipment, such as an aerobic section in a biological tank, an ozone contact tank, ozone / hydrogen peroxide advanced oxidation, etc. In the water treatment process, medicine needs to be added while aeration is performed to improve the water treatment effect.

[0003] The existing medicine adding mode is to use a medicine pipe to add medicine separately. There are many types of medicine, and some types of medicine will react with the aeration gas, which reduces the water treatment effect. Therefore, the medicine injection position needs to be separated from the aeration position. However, this medicine adding mode cannot improve the diffusion rate and diffusion effect of the medicine, and the aeration and the medicine are relatively independent, which makes it difficult to promote each other. In addition, when the aeration disc is aerated, the gas is mainly aerated from the middle of the aeration film, and less gas is aerated from the periphery of the aeration film. The uneven aeration position reduces the fineness of the bubbles and makes it difficult to disperse in the water, so the gas is more likely to gather and react with the medicine.

[0004] Therefore, it is necessary to provide a multi-purpose aeration head capable of aeration and medicine adding, which can improve the diffusion rate and diffusion effect of the medicine and avoid the reaction between the aeration gas and the medicine. SUMMARY

[0005] The present application aims to solve the problems of low medicine diffusion rate, poor diffusion effect, and reaction between the aeration gas and the medicine in the existing medicine adding mode. The present application provides a multi-purpose aeration head capable of aeration and medicine adding.

[0006] The technical scheme of the present application is as follows:

[0007] A multi-purpose aeration head capable of aeration and medicine adding, comprising an upper cover and a base, the upper cover is a gas permeable structure and is covered with a film for aeration on the outer side, the upper cover is buckled on the top of the base, and a gas aeration cavity for gas passing through is left between the upper cover and the base;

[0008] The air pipe and the medicine adding pipe placed in the air pipe are further included, the air pipe is communicated with the gas aeration cavity, and the medicine adding pipe is dispersed into a plurality of branch pipes in the gas aeration cavity, passes through the upper cover, and extends to the outer side of the upper cover to form a high-position medicine pipe.

[0009] A low-position medicine pipe communicated with the medicine adding pipe is arranged in the gas aeration cavity, the upper cover is provided with a medicine outlet, and the upper cover can be lifted relative to the base. When the upper cover is lowered to a low position, the low-position medicine pipe discharges medicine through the medicine outlet. When the upper cover is raised to a high position, the low-position medicine pipe stops discharging medicine.

[0010] Further, the low-position medicine pipe comprises an inner pipe and an outer pipe sleeved on the inner pipe, the inner pipe is fixed on the base and communicated with the medicine adding pipe, and the outer pipe is fixed on the upper cover and communicated with the medicine outlet.

[0011] The extrusion opening and closing device is arranged between the inner tube and the outer tube, the extrusion opening and closing device is closed when the upper cover is lifted to the high position to stop the medicine outlet, the extrusion opening and closing device is opened when the upper cover is lowered to the low position to allow the medicine outlet, the extrusion opening and closing device has different medicine release rates when the upper cover is at the high position and the low position, the upper cover is lowered to the low position when the medicine does not react with the aeration gas, the high-position medicine tube and the low-position medicine tube simultaneously release the medicine, the medicine release rate is high, and the sewage treatment is convenient and efficient; the upper cover is lifted to the high position when the medicine reacts with the aeration gas, the high-position medicine tube releases the medicine, and the low-position medicine tube stops releasing the medicine, the medicine release rate is greatly ensured while the medicine does not react with the aeration gas, and the sewage treatment efficiency is ensured.

[0012] Further, the extrusion opening and closing device comprises a medicine adding hose, a medicine adding hard tube and pressure wheels arranged in opposition on both sides of the medicine adding hard tube, the pressure wheels are installed on the inner wall of the outer tube, one end of the medicine adding hard tube is connected with the inner tube, and the other end of the medicine adding hard tube is connected with the medicine adding hose, the outer tube moves relative to the inner tube to drive the pressure wheels to roll along the medicine adding hard tube, the pressure wheels deform the medicine adding hose from both sides to the middle when the pressure wheels roll to the medicine adding hose to stop the medicine outlet, the structure complexity between the inner tube and the outer tube and the mechanism operation stability can be greatly simplified, the medicine adding hose and the medicine adding hard tube are combined, the low-position medicine tube is stopped from releasing the medicine by deforming the medicine adding hose, the upper cover has different medicine release rates when the upper cover is at the high position and the low position, the medicine release rate is flexibly controlled, and the practicability is high.

[0013] Further, the pressure wheels are rotationally connected with the inner wall of the outer tube through rotating shafts, the rotating shafts are sleeved with springs, the springs drive the pressure wheels to extrude the pressure wheels in opposition, the pressure wheels in opposition can approach each other through the spring to form extrusion force on the medicine adding hose and the medicine adding hard tube between the two pressure wheels, and the medicine adding hose is deformed and the medicine in the medicine adding hose is blocked when the pressure wheels move to the medicine adding hose.

[0014] Further, one end of the medicine adding hard tube connected with the medicine adding hose is flat, the flat connection can ensure smooth transition between the two, facilitate the control and treatment of the sealing property of the connection, and the pressure wheels can also move smoothly when passing through the connection, and the connection will not be stuck, and the flat connection between the two is more conducive to the deformation of the medicine adding hose by the pressure wheels, and ensures the stability of the low-position medicine tube in controlling the medicine release.

[0015] Further, a one-way valve is arranged at the medicine outlet to avoid the backflow of the medicine.

[0016] Further, one end of the medicine adding hose is fixed in the outer tube and communicates with the outer tube.

[0017] Furthermore, a sealing ring is provided on the inner side of the outer pipe to seal the gap between the outer and inner pipes, ensuring the isolation of the space inside the pipe from external sewage and preventing the agent from overflowing from the gap.

[0018] Furthermore, the top cover is slidably connected to the base, and the top cover is connected to a telescopic device, which causes the top cover to slide relative to the base.

[0019] Furthermore, the telescopic device is a cylinder.

[0020] This invention relates to a multi-purpose aeration head that can perform both aeration and dosing. A newly designed dosing pipe is incorporated within the air pipe used for aeration, enabling simultaneous aeration and dosing. The agitation generated by the aeration effectively increases the mixing speed of the added medication in the wastewater, combining aeration and dosing functions. The added medication may react with the aeration gas or not. When there is no reaction, the top cover lowers to the low position, allowing both the low and high-level dosing pipes to dispense medication simultaneously, increasing the discharge rate and facilitating faster mixing with the wastewater due to the agitation of the aeration gas, thus improving mixing efficiency. When there is a reaction, the top cover rises to the high position. The high-level dosing pipe, being at a higher position, avoids immediate contact with the aeration gas, preventing reaction and allowing continued medication dispensing. The low-level dosing pipe closes, stopping medication dispensing and preventing reaction. Compared to traditional technologies, this design maximizes the diffusion rate of the medication while preventing reaction. Attached Figure Description

[0030] To make the technical means, technical features, inventive purpose and technical effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0031] Example 1:

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, a multi-purpose aerator head capable of both aeration and medication dispensing includes an upper cover 1 and a base 2. The upper cover 1 has a breathable structure and is covered with a membrane 3 for aeration on its outer side. The upper cover 1 is fastened to the top of the base 2, with an aeration chamber 4 between them for gas passage. It also includes an air pipe 5 and a medication dispensing pipe 6 placed inside the air pipe 5. The air pipe 5 communicates with the aeration chamber 4. The medication dispensing pipe 6 is distributed into multiple branch pipes 17 within the aeration chamber 4, passing through the upper cover 1 and extending to the outside of the upper cover 1, forming a high-level medication pipe 7. A low-level medication pipe 8 communicating with the medication dispensing pipe 6 is provided within the aeration chamber 4. The upper cover 1 has a medication outlet 9 and can be raised and lowered relative to the base 2. When the upper cover 1 is lowered to the low position, the low-level medication pipe 8 dispenses medication through the medication outlet 9; when the upper cover 1 is raised to the high position, the low-level medication pipe 8 stops dispensing medication. This is an optional configuration, such as... Figure 3 As shown, the branch pipe 17 extending from the dosing pipe 6 in the high-level dosing pipe 7 is spiral-shaped, so that the gas coming out of the air pipe 5 can generate a spiral, thereby making the gas contact with the membrane 3 very uniform and the generated bubbles are also very uniformly distributed, improving the aeration effect. As an alternative, the low-level dosing pipe 8 can also have a section of the pipe extending from the dosing pipe 6 designed as a spiral, specifically, the inner pipe 10 or a section of the inner pipe 10 is designed as a spiral, so as to generate a spiral together with the high-level dosing pipe 7.

[0033] Preferred, such as Figure 4As shown, the low-level dosing tube 8 includes an inner tube 10 and an outer tube 11 sleeved on the inner tube 10. The inner tube 10 is welded to the base 2 and connected to the dosing tube 6. The outer tube 11 is welded and fixed to the upper cover 1 and connected to the dosing outlet 9. A squeeze-opening device is provided between the inner tube 10 and the outer tube 11. When the upper cover 1 is raised to the high position, the squeeze-opening device closes to stop the dosing. When the upper cover 1 is lowered to the low position, the squeeze-opening device opens to dispensing the dosing. The squeeze-opening device can provide different dosing rates when the upper cover 1 is at two different heights, high and low. When the dosing does not react with the aeration gas, the upper cover 1 is lowered to the low position, and both the high-level dosing tube 7 and the low-level dosing tube 8 dispense the dosing simultaneously, resulting in a high dosing rate and convenient and efficient wastewater treatment. When the dosing reacts with the aeration gas, the upper cover 1 is raised to the high position, the high-level dosing tube 7 dispenses the dosing, and the low-level dosing tube 8 stops dispensing the dosing. This ensures that the dosing does not react with the aeration gas while maximizing the dosing rate and ensuring wastewater treatment efficiency.

[0034] Preferred, such as Figure 6 and Figure 7 As shown, the squeeze opening and closing device includes a dosing hose 12, a dosing rigid tube 13, and pressure rollers 14 arranged opposite each other on both sides of the dosing rigid tube 13. The pressure rollers 14 are installed on the inner wall of the outer tube 11. One end of the dosing rigid tube 13 is connected to the inner tube 10, and the other end of the dosing rigid tube 13 is connected to the dosing hose 12. When the outer tube 11 moves relative to the inner tube 10, it drives the pressure rollers 14 to roll along the dosing rigid tube 13. When the pressure rollers 14 roll onto the dosing hose 12, they squeeze from both sides of the dosing hose 12 toward the middle to deform it, thereby stopping the dispensing of medicine. This dispensing method can greatly simplify the structural complexity and operational stability between the inner tube 10 and the outer tube 11. By combining the dosing hose 12 and the dosing rigid tube 13, the dispensing of medicine from the low-position medicine tube 8 is stopped by squeezing the hose to deform it. This allows the upper cover 1 to have different drug release rates when it is in a high position and a low position. The drug release rate can be flexibly controlled, and the device is highly practical.

[0035] Preferred, such as Figure 7 and Figure 8 As shown, the pressure roller 14 is rotatably connected to the inner wall of the outer tube 11 via a rotating shaft 15. The rotating shaft 15 is fitted with a spring 16. The spring 16 drives the pressure roller 14 to squeeze the opposing pressure roller 14. The opposing pressure rollers 14 can move closer to each other through the spring 16, thereby forming a squeezing force on the dosing hose 12 and the dosing rigid tube 13 between them. When the pressure roller 14 moves to the dosing hose 12, it can squeeze the dosing hose 12 to deform and seal the agent in the dosing hose 12.

[0036] Preferred, such as Figure 7 and Figure 8As shown, the end where the dosing tube 13 connects to the dosing hose 12 is flat. The flat connection ensures a smooth transition between the two, making it easy to control and handle the sealing of the connection. At the same time, the pressure roller 14 can also move smoothly when passing through this point without getting stuck. Moreover, the flat design of the connection makes it easier for the pressure roller 14 to squeeze the dosing hose 12 and deform it, ensuring the stability of the drug release controlled by the lower dosing tube 8.

[0037] Specifically, the pressure rollers 14 can have various different shapes. For example, the contact surface between the pair of pressure rollers 14 can be arc-shaped, with one pressure roller 14 being a concave arc shape and the other pressure roller 14 being a matching convex arc shape. Of course, with this shape of pressure roller 14, the flat end connecting the dosing tube 13 and the dosing hose 12 also has a matching arc shape. The contact surface between the pair of pressure rollers 14 can also be bent, with one pressure roller 14 being a concave bent shape and the other pressure roller 14 being a matching convex bent shape. Similarly, the flat end connecting the dosing tube 13 and the dosing hose 12 also has a corresponding bent shape.

[0038] Preferably, a one-way valve is provided at the nine drug outlets to prevent drug backflow.

[0039] Preferably, one end of the dosing hose 12 is fixed inside the outer tube 11 and connected to the outer tube 11.

[0040] Preferably, a sealing ring is provided on the inner side of the outer pipe 11 to seal the gap between the outer pipe 11 and the inner pipe 10, ensuring the isolation of the space inside the pipe from the external sewage and preventing the agent from overflowing from the gap.

[0041] Preferred, such as Figure 3 As shown in the figure, the upper cover 1 and the base 2 are slidably connected by a guide rail. The upper cover 1 is connected to a telescopic device 18, which drives the upper cover 1 to slide relative to the base 2.

[0042] Preferably, the telescopic device 18 is a cylinder.

[0043] When using, such as Figure 6 and Figure 7As shown, the aeration head of this invention incorporates a newly designed dosing pipe 6 within the air pipe 5 used for aeration, enabling it to perform dosing simultaneously with aeration. The agitation caused by the aeration effectively increases the mixing speed of the added medication in the wastewater, combining aeration and dosing functions. Furthermore, since the added medication may react with or not react with the aeration gas, to maximize the release efficiency of the medication and ensure maximum diffusion of the medication by the aeration gas, when there is no reaction, the top cover 1 can be lowered to a low position. At this time, the pressure roller 14 is located at the dosing rigid pipe 13, the dosing hose 12 is unobstructed, and the medication can be smoothly released from the low-level dosing pipe 8. The low-level dosing pipe 8 and the high-level dosing pipe 7 can simultaneously dispense medication, increasing the discharge speed of the liquid. Under the agitation of the aeration gas, it can mix more quickly with the wastewater, improving mixing efficiency. When there is a reaction, such as... Figure 1 and Figure 8 As shown, when the upper cover 1 is raised to the high position, the pressure roller 14 in the low-position dosing tube 8 moves from the dosing rigid tube 13 to the dosing flexible tube 12. Under the elastic force of the spring 16, the pressure rollers 14 on both sides of the dosing flexible tube 12 begin to squeeze the dosing flexible tube 12, thereby deforming it and sealing the dosing flexible tube 12. The agent cannot be released from the low-position dosing tube 8, thus avoiding the phenomenon that the agent released from the low-position dosing tube 8 reacts with the aeration gas. Since the high-position dosing tube 7 is in a high position, it will not come into contact with the aeration gas immediately. When the gas rises to the height of the high-level drug pipe 7, its concentration is no longer high enough to react with the drug, thus avoiding the reaction. The drug can continue to be discharged, while the low-level drug pipe 8 is closed and the drug outlet 9 stops discharging the drug to prevent the two from reacting. Although the discharge rate of the drug is reduced to some extent, the diffusion effect of the aeration gas on the released drug is preserved to the maximum extent, which is beneficial to sewage treatment. At the same time, it improves the flexibility of the aeration head in dealing with the above two situations and improves the practicality of the aeration head.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. All equivalent changes and modifications made in accordance with the scope of the claims of this invention should fall within the technical scope of this invention.
