Description

Technical Field

[0001] This utility model relates to the field of aeration device technology, specifically to an aeration device. Background Technology

[0002] An aeration device is a device that supplies oxygen to the aeration tank in the activated sludge process of wastewater treatment. Essentially, it introduces air into the biological aeration tank through appropriate equipment to achieve the desired purpose. The aeration device not only allows the liquid in the tank to come into contact with air and be oxygenated, but also agitates the liquid, accelerating the transfer of oxygen from the air into the liquid, thereby completing the purpose of oxygenation. In the salt and quality separation project of water treatment, the high-concentration brine conditioning tank contains a large amount of suspended solids and a lot of sludge at the bottom of the tank, which affects the operation of the overall equipment.

[0003] A search revealed Chinese patent CN222293810U, which discloses an aeration device including an aeration shell, multiple sets of aeration holes evenly distributed on the bottom surface of the aeration shell, and a sealing mechanism disposed within the aeration shell. The aeration shell has air pipe connection holes on both sides, communicating with an external air supply pipe. The sealing mechanism is a telescopic mechanism; its fixed end is disposed within the aeration shell, and its telescopic end extends from within the aeration shell through the aeration holes to the outside of the aeration shell, where it is detachably connected to a guide cover. The guide cover has a diameter larger than the aeration holes. This invention provides an aeration device by setting a sealing mechanism within the main shell of the device and configuring it as a spring-compressed mechanism. This allows the guide cover to automatically seal the aeration holes on the aeration shell when no airflow enters, thus automatically keeping the device in a closed state and preventing suspended matter from entering and clogging the aeration holes.

[0004] The aforementioned patent has the following shortcomings: After the equipment completes aeration, the lifting rod is retracted by the spring, which seals the aeration holes with the guide cover. However, since the aeration holes stop blowing air outward, when the lifting rod retracts, the brine solution will enter the equipment through the aeration holes. The brine entering the equipment will corrode components such as the spring, affecting the service life of the equipment. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an aeration device to solve the technical problem that salt water entering the equipment corrodes components such as springs, affecting the service life of the equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an aeration device, comprising a main body and a protective mechanism, wherein the protective mechanism includes a connecting pipe, an air valve is provided on the connecting pipe, an inflation pipe is provided at one end of the connecting pipe, and an air bladder is provided at one end of the inflation pipe.

[0007] By adopting the above technical solution, the air valve can control the flow and on / off of gas, thereby regulating the inflation of the airbag.

[0008] Furthermore, there are two connecting pipes, which are symmetrically arranged along the central axis of the main body.

[0009] By adopting the above technical solution, the two connecting pipes are symmetrically arranged along the central axis of the main body, which helps to maintain the balance and stability of the overall structure.

[0010] Furthermore, the airbags are provided in a plurality of units, which are arranged in a linear array at equal intervals.

[0011] By adopting the above technical solution, since several airbags are arranged in a linear array at equal intervals, they can provide more comprehensive and uniform protection.

[0012] Furthermore, an air pipe is provided on one side of the main body, and a fixing block is provided inside the main body.

[0013] By adopting the above technical solution, the air pipe is located on one side of the main body, which facilitates connection with an external air source, thereby ensuring that the gas can smoothly enter the aeration device.

[0014] Furthermore, a limit rod is provided at the top of the fixed block, and a movable block is connected to the top of the fixed block by a spring.

[0015] By adopting the above technical solution, the setting of the limit rod provides a stable up-and-down movement track for the movable block, ensuring that the movable block will not deviate from the predetermined path during movement.

[0016] Furthermore, connecting rods are provided on both sides of the movable block, and a movable rod is provided at the bottom of the connecting rods.

[0017] By adopting the above technical solution, the connecting rod, as a transmission component, can efficiently convert the movement of the movable block into the movement of the movable rod.

[0018] Furthermore, an aeration hole is provided on the outer side of the movable rod, and a cap is provided at one end of the movable rod.

[0019] By adopting the above technical solution, the aeration holes opened on the outside of the movable rod allow gas to escape flexibly from these holes for aeration operation.

[0020] In summary, the present invention has the following main advantages:

[0021] 1. This utility model, by setting up a connecting pipe, an air valve, and an air bladder, can inflate the air bladder when the equipment stops aeration, filling and covering the aeration holes. This effectively prevents external liquid from seeping into the device through the aeration holes, improves the device's protective capability, avoids corrosion of internal components, and extends the service life of the equipment. The flexible control of the air valve allows the inflation and deflation of the air bladder to be completed quickly, ensuring the timeliness and effectiveness of the protective mechanism.

[0022] 2. This utility model, by setting up a spring, an aeration hole, and a cover, utilizes the elastic force of the spring. When the airbag inflates to protect the aeration hole, the spring can drive the cover to reset, so that the cover accurately seals the aeration hole, effectively preventing external impurities and liquids from entering the device, avoiding blockage of the aeration hole, protecting internal components, and increasing the service life of the equipment.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] An aeration device, such as Figures 1-4 As shown, it includes a main body 1 and a protective mechanism 3. The protective mechanism 3 includes a connecting pipe 301, an air valve 302 is provided on the connecting pipe 301, an inflation pipe 303 is provided at one end of the connecting pipe 301, and an airbag 304 is provided at one end of the inflation pipe 303. The air valve 302 can control the flow rate and on / off of the gas, thereby regulating the inflation of the airbag 304. The inflation pipe 303 plays a transition and connection role, guiding the gas from the connecting pipe 301 into the airbag 304.

[0030] See Figure 1 , Figure 2 , Figure 3 There are two connecting pipes 301, which are symmetrically arranged along the central axis of the main body 1. The symmetrical arrangement of the two connecting pipes 301 along the central axis of the main body 1 helps to maintain the balance and stability of the overall structure. The two symmetrically arranged connecting pipes 301 can ensure that the gas is more evenly distributed to the various components of the device.

[0031] See Figure 3 The airbags 304 are arranged in a linear array at equal intervals. Because the airbags 304 are arranged in a linear array at equal intervals, they can provide more comprehensive and uniform protection. The uniform distribution of multiple airbags 304 can effectively disperse external impact or pressure, reduce the situation of excessive force on a single point, and thus extend the service life of the device.

[0032] See Figure 1 An air pipe 2 is provided on one side of the main body 1, and a fixing block 4 is provided inside the main body 1. The air pipe 2 is located on one side of the main body 1, which facilitates connection with an external air source, thereby ensuring that the gas can smoothly enter the aeration device. The fixing block 4 plays a supporting and stabilizing role inside the main body 1, providing a stable installation base for other components.

[0033] See Figure 1 The top of the fixed block 4 is provided with a limit rod 5, and the top of the fixed block 4 is connected to the movable block 7 by a spring 6. The limit rod 5 provides a stable up and down moving track for the movable block 7, ensuring that the movable block 7 will not deviate from the predetermined path during movement. The movable block 7 and the fixed block 4 are connected by the spring 6, realizing the automatic reset function of the movable block 7.

[0034] See Figure 3 Connecting rods 8 are provided on both sides of the movable block 7, and a movable rod 9 is provided at the bottom of the connecting rods 8. As a transmission component, the connecting rods 8 can efficiently convert the movement of the movable block 7 into the movement of the movable rod 9. The connecting rods 8 enhance the overall stability of the device and ensure the smoothness and accuracy of the moving parts during the movement process.

[0035] See Figure 1 , Figure 2 The movable rod 9 has an aeration hole 11 on its outer side and a cover 10 at one end. The aeration hole 11 on the outer side of the movable rod 9 allows gas to escape flexibly from these holes for aeration. The cover 10 can effectively seal the aeration hole 11 when aeration is not needed to prevent gas leakage or external impurities from entering the device.

[0036] The implementation principle of this utility model is as follows: First, when aeration is to be stopped, the air valve 302 is opened by the external controller, allowing gas to enter the inflation pipe 303 through the connecting pipe 301 and fill the air bag 304, so that the air bag 304 fills the aeration hole 11. Then, the air valve 302 is closed, and the air pipe 2 gradually stops inflating. Then, the spring 6 drives the movable block 7 to contract, causing the connecting rod 8 to drive the movable rod 9 to move, so that the cover 10 closes the aeration hole 11. Then, the air valve 302 is opened again, and the gas in the air bag 304 gradually flows out through the connecting pipe 301, causing the air bag 304 to contract, so that the equipment can continue to be used.

[0037] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
