Description

Technical Field

[0001] This invention relates to the field of water treatment, and more specifically to a telescopic structure for a deep-water aeration device. Background Technology

[0002] Deep-water aeration and reoxygenation technology is gradually becoming the preferred technology in the field of water body remediation and treatment. Its principle utilizes the characteristics of high water pressure, low dissolved oxygen, and high mass transfer efficiency in deep water areas. By organically combining oxygenation and water lifting through an aeration chamber, it achieves a unified function. The principle of deep-water aeration devices is to inject air into the bottom of the water body. As the reoxygenated water rises to the surface, it drives the exchange of water between the upper and lower layers of the deep-water reservoir. Existing reoxygenation systems suffer from unreasonable flow field settings. This is mainly because the deep-water aeration device changes with water depth, making it impossible to ensure that the inlet is always located at the bottom, resulting in insufficient disturbance of bottom sediments. Furthermore, the deep-water aeration device cannot guarantee verticality due to water fluctuations, affecting the upward flow path and reducing gas utilization. Utility Model Content

[0003] To address the problems of existing deep-water aeration devices failing to ensure that the inlet is always at the bottom of the water body and failing to guarantee verticality, this utility model proposes a telescopic structure for deep-water aeration devices.

[0004] This utility model discloses a telescopic structure for a deep-water aeration device, characterized in that the structure includes a pulse air chamber and a riser pipe. The pulse air chamber is a hollow cylinder, comprising an inner air chamber and an outer air chamber. Both the inner and outer air chambers have conical openings at their bottoms that communicate with the water body. A return outlet is also provided in the middle of the outer air chamber's outer wall, and a baffle plate is installed at the return outlet. The outer and inner air chambers are connected through a U-shaped air outlet slit. The inner air chamber is connected to the riser pipe. A first watertight chamber is arranged around the outer air chamber. An anchor chain is provided at the bottom of the pulse air chamber, and the anchor chain is connected to a sinker. The riser pipe adopts a three-section structure, with the lower section connecting to the pulse air chamber. The air chamber is connected via a flange; the middle pipe section is fitted inside the lower pipe section, and a rubber ring is fixedly installed at the bottom of the middle pipe section, which fits the inner diameter of the lower pipe section; the inner air chamber has the same diameter as the lower pipe section, and an annular boss is fixedly installed below the air outlet slit of the inner air chamber, allowing the middle pipe section to slide down along the lower pipe section into the inner air chamber; a second watertight chamber is arranged around the middle pipe section to maintain neutral buoyancy; the upper pipe section is fitted inside the middle pipe section, and a third watertight chamber is arranged around the upper pipe section to maintain positive buoyancy, allowing the upper pipe section to automatically adjust the outlet height as the liquid level changes.

[0005] During use, since the second watertight chamber adopts neutral buoyancy, the size of the air outlet slit can be adjusted by adjusting the height of the middle pipe section to obtain the optimal aeration rate, pulse air volume and water lifting volume for a single aeration; when the middle pipe section moves to the lowest point, the rubber ring on the middle pipe section contacts the annular boss, thus sealing the air outlet slit.

[0006] The rubber ring serves two purposes: firstly, it acts as a sealing layer to prevent gas escape due to gaps between the middle and lower pipe sections; secondly, it acts as a buffer layer to prevent damage to the annular boss, especially when the water level is too low, as excessive compression of the riser pipe can increase the stress on the annular boss. Additionally, the annular boss reduces the inner diameter of the air chamber, forming a throat, while increasing the inner diameter of the riser pipe section, forming a diffuser section. This allows for thorough mixing of compressed air and bottom water flow, creating an air-water mixture and enhancing the aeration effect.

[0007] Furthermore, a positioning clamp is installed on the middle pipe section below the second watertight chamber, which is used to lock the relative position of the middle pipe section and the lower pipe section when the middle pipe section falls, so as to maintain the size of the air outlet slit.

[0008] Furthermore, an H-shaped grooved wheel is provided radially on the outer side of the middle section of the riser pipe; linear guide rails are provided along the length direction on the inner walls of the upper and lower sections of the riser pipe, and the H-shaped grooved wheel slides along the linear guide rails to maintain the smoothness and stability of the movement of each part of the riser pipe.

[0009] The telescopic structure of the deep-water aeration device of the present invention has the following characteristics:

[0010] The riser pipe is always suspended on the surface of the water body or at a fixed position at the bottom of the water body, which has strong stability. Combined with the conical design of the outer and inner air chambers and the baffle design of the return port, the bottom water is fully replaced, which enables the reoxygenation system to operate efficiently.

[0011] The riser pipe adopts a three-section design, with independent buoyancy control for each section, resulting in strong stability and helping to maintain the sag of the entire system. The middle section can also be used to adjust the aeration rate, while the height of the upper section above the water surface is adjustable, facilitating the control of the water lifting capacity of the reoxygenation device.
