Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, and more specifically, to a disc aeration device. Background Technology

[0002] A disc aerator is a device used in wastewater treatment, primarily for introducing air into wastewater to promote the oxidative decomposition of organic matter. During operation, an air pump supplies air into the disc aerator, which then distributes the air evenly throughout the wastewater, forming tiny bubbles. This increases the contact area between the wastewater and air, thereby improving oxygen transfer efficiency.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] Reference Figures 1 to 5As shown, this utility model discloses a disc aeration device, which includes a disc body 100, a diaphragm 200, and a mounting plate 300. The outer peripheral wall of the disc body 100 is provided with an annular positioning groove 101, and a flange 110 is provided at the upper end of the annular positioning groove 101. At least one clearance groove 111 is provided on the flange 110; specifically, in this embodiment, six clearance grooves 111 are evenly arranged along the circumference of the flange 110. An installation groove 102 is provided on the inner peripheral wall of the disc body 100. The diaphragm 200 is placed in the installation groove 102. The fastening plate 300 is provided with a fastening part 310 and an installation part 320. The fastening part 310 abuts against the diaphragm 200, and the installation part 320 is sleeved on the disc body 100. A locking block 321 is provided on the inner peripheral wall of the installation part 320 corresponding to the clearance groove 111. The locking block 321 can enter the annular positioning groove 101 through the clearance groove 111. After the fastening plate 300 is rotated, the locking block 321 and the clearance groove 111 can be misaligned, and the locking block 321 can abut against the lower end face of the flange 110. Through the design of the fastening plate 300, the fastening plate 300 and the disc body 100 can be locked or unlocked by rotating the fastening plate 300, thereby facilitating the replacement of the diaphragm 200. The working principle of this disc aerator is based on compressed air being introduced from the bottom of the device, diffusing into the water through the micropores of the diaphragm 200, forming a large number of tiny bubbles, thereby increasing the dissolved oxygen content of the water. Compared with traditional aeration methods, the special design of the diaphragm 200 in this device ensures uniform gas distribution and improves oxygen transfer efficiency. The diaphragm 200 is easy to replace and clean, effectively reducing maintenance costs. The design of the retaining plate 300 ensures the stability of the diaphragm 200 position, reducing the risk of damage caused by water flow impact. It is suitable for application needs under various water quality conditions, and can efficiently treat both domestic sewage and industrial wastewater. At the same time, replacing the diaphragm 200 reduces the damage rate of the disc 100 or retaining plate 300, increasing the service life of the device and thus reducing the maintenance frequency.

[0032] In some embodiments of this utility model, a sealing ring 210 is provided at the lower end of the buckle plate 300. Since the sealing ring 210 is elastic, providing a sealing ring 210 at the lower end of the buckle plate 300 can prevent the buckle plate 300 from rotating during normal operation. Specifically, in this embodiment, the sum of the thicknesses of the sealing ring 210 and the snap-fit ​​block 321 is greater than the width of the annular positioning groove 101.

[0033] In some embodiments of this invention, a funnel portion 120 is provided at the lower end of the disc body 100. In this embodiment, compressed air is introduced from the bottom of the device and diffuses into the water through the micropores of the diaphragm 200, forming a large number of tiny bubbles. Through the design of the funnel portion 120, a natural diversion effect can be formed, evenly distributing the gas to each micropore on the diaphragm 200, avoiding the phenomenon of uneven bubble size, and at the same time improving the structural strength of the disc body 100.

[0034] In some embodiments of this invention, a plurality of reinforcing ribs 121 are provided on the outer peripheral wall of the funnel portion 120 along the generatrix direction of the funnel portion 120. In this embodiment, the disc body 100 is subjected to pressure from different directions during operation, such as water flow impact and air pressure fluctuations, which can easily cause the funnel portion 120 to bend or twist. By adding reinforcing ribs 121, the structure gains stronger support, effectively distributes the load, and ensures that the funnel portion 120 maintains its original shape and a stable working state.

[0035] In some embodiments of this utility model, an air inlet pipe 130 is provided at the lower end of the funnel portion 120, and a one-way valve 140 is provided on the air inlet pipe 130. Specifically, in this embodiment, the air inlet pipe 130 is connected to the funnel portion 120 for introducing high-pressure gas. By providing the one-way valve 140 on the air inlet pipe 130, the one-way valve 140 can automatically close in the event of system shutdown or abnormal pressure, effectively preventing water or other impurities from flowing back to the input end of the air inlet pipe 130, protecting the gas source from contamination. This maintains the cleanliness of the aeration system, extends the service life of the equipment, and thus reduces the frequency of equipment maintenance.

[0036] In some embodiments of this utility model, a hexagonal prism 131 is provided on the outer peripheral wall of the air inlet pipe 130. By providing the hexagonal prism 131 on the air inlet pipe 130, when the entire disc aeration device needs to be replaced, a hexagonal wrench can be used to replace the entire aeration device.

[0037] In some embodiments of this invention, a support plate 220 is provided at the upper end of the diaphragm 200, and the support plate 220 has honeycomb-shaped holes 221. One end of the support plate 220 abuts against the fastening part 310 of the buckle plate 300, and the other end of the support plate 220 abuts against the diaphragm 200. In this embodiment, the support plate 220 provides a temperature-controlled plane, preventing the diaphragm 200 from collapsing or deforming during operation, ensuring its shape integrity, and facilitating uniform gas diffusion. Adding a support plate 220 above the diaphragm 200 significantly improves the mechanical strength of the entire system, resisting external impacts and fatigue damage under long-term use. In addition, the support plate 220 helps maintain the stable operating temperature of the diaphragm 200 under high temperature or extreme climatic conditions, avoiding expansion and contraction problems caused by temperature changes. Furthermore, the hexagonal honeycomb-shaped holes 221 effectively disperse the resistance to gas flow, reduce eddy current generation, and make the gas flow more smoothly through the holes, reducing energy loss.

[0038] In some embodiments of this utility model, a plurality of anti-slip grooves 301 are provided on the outer peripheral wall of the buckle plate 300. By providing anti-slip grooves 301, it is convenient for maintenance personnel to rotate the buckle plate 300, thereby facilitating the installation or removal of the buckle plate 300.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
