Description

Technical Field

[0001] This utility model belongs to the technical field of sewage treatment equipment, specifically relating to a disc-type microporous aeration device for sewage treatment. Background Technology

[0002] Disc-type microporous aerators are wastewater treatment equipment. These devices feature small aeration bubble diameters, small gas-liquid interface diameters, large gas-liquid interface areas, uniform bubble diffusion, and strong corrosion resistance. In current wastewater treatment practices, aeration devices, as core oxygen supply facilities, play a crucial role in increasing dissolved oxygen levels in wastewater, promoting microbial reproduction, and decomposing organic matter. However, due to prolonged continuous operation, the aeration disc pores of the aeration device may become clogged, leading to a decrease in oxygenation efficiency and adversely affecting the effectiveness and efficiency of wastewater treatment. Therefore, regular maintenance is essential. Maintenance work mainly includes removing scale, checking the integrity of the aeration discs, and ensuring their normal operation. However, current disc-type microporous aerators typically require emptying the aeration tank during maintenance, which not only increases operational complexity and cost but also impacts the continuous operation of the wastewater treatment plant. In view of this, this utility model proposes an innovative disc-type microporous aeration device for sewage treatment, which can be installed and maintained directly above the aeration tank without emptying the aeration tank, effectively reducing the difficulty and cost of maintenance.

[0003] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

The guide is symmetrically fixed to both sides of the aeration tank wall by anchors. The fixing component is symmetrically fixed to both sides of the top of the aeration tank by anchors. A flotation component is provided at the bottom of the aeration assembly. The aeration assembly includes an air supply pipe. One end of the air supply pipe is connected to an air distribution pipe. The end of the air supply pipe is connected to the center of the air distribution pipe. Air outlet pipes are evenly connected to both ends of the air distribution pipe. Aeration discs are evenly installed on the air outlet pipe. A safety net is fixed between the air supply pipe, the air distribution pipe, and the air outlet pipe. Limiting rods are fixedly connected to both ends of the air outlet pipe. The limiting rods are fixed to the aeration tank body by the guide and the fixing component.

[0005] As a preferred technical solution of this utility model, the buoyancy component includes an electric three-way reversing air valve, which is installed at the connection between the air supply pipe and the air distribution pipe. The air inlet of the electric three-way reversing air valve is connected to the air supply pipe, one of the air outlets of the electric three-way reversing air valve is connected to the body of the air distribution pipe, and the other air outlet of the electric three-way reversing air valve is connected to a buoyancy airbag.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example

[0018] Please see Figure 1-3 This utility model provides the following technical solution: a disc-type microporous aeration device for sewage treatment, comprising a guide 1, a fixing 2, and an aeration assembly. The guide 1 is firmly fixed to both sides of the aeration tank wall in a symmetrical manner using anchors to ensure the stable rising and falling of the aeration assembly. Similarly, the fixing 2 is symmetrically fixed to both sides of the top of the aeration tank body using anchors to ensure the aeration assembly is firmly fixed to the bottom of the aeration tank. A floating assembly is provided at the bottom of the aeration assembly to facilitate automatic lifting of the aeration assembly to the water surface of the aeration tank during maintenance. The aeration assembly mainly includes an air supply pipe 3, one end of which is connected to an air distribution pipe 4. The end of the air supply pipe 3 and the center of the air distribution pipe 4 are tightly connected. Air outlet pipes 5 are evenly connected to both ends of the air distribution pipe 4 to ensure uniform gas transmission. Aeration discs 6 are evenly installed on the air outlet pipes 5 to ensure uniform aeration, improve oxygen utilization, and increase sewage treatment efficiency. In addition, safety nets 7 are fixed between the air supply pipe 3, the air distribution pipe 4, and the air outlet pipe 5 to facilitate stepping on the aeration disc 6 during later maintenance. Limiting rods 8 are fixedly connected to both ends of the air outlet pipe 5, and the limiting rods 8 are fixed to the aeration tank body through guide parts 1 and fixing parts 2.

[0019] To facilitate automatic floating during maintenance and reduce maintenance difficulty, in this embodiment, as a preferred technical solution of the present invention, the floating component includes an electric three-way reversing air valve 9. The electric three-way reversing air valve 9 is installed at the connection between the air supply pipe 3 and the air distribution pipe 4. The air inlet of the electric three-way reversing air valve 9 is connected to the air supply pipe 3, one of the air outlets of the electric three-way reversing air valve 9 is connected to the body of the air distribution pipe 4, and the other air outlet of the electric three-way reversing air valve 9 is connected to a floating airbag.

[0020] In order to ensure uniform buoyancy, in this embodiment, as a preferred technical solution of the present invention, the buoyancy airbag includes an air supply pipe 11, and airbag bodies 12 are evenly connected to both sides of the air supply pipe 11. The airbag bodies 12 are fixed to the bottom of the safety net 7.

[0021] In order to ensure the service life of the electric three-way reversing air valve 9, in this embodiment, as a preferred technical solution of the present invention, a sealing shell is provided on the outside of the electric three-way reversing air valve 9, and the sealing shell is fixed to the air supply pipe 3.

[0022] In order to ensure the structural and fixing strength of the guide 1 and the fixing 2, in this embodiment, as a preferred technical solution of the present invention, both the guide 1 and the fixing 2 include a fixing base 14, an upper pressure plate 13 and a lower pressure plate 10. The lower pressure plate 10 and the fixing base 14 are fixedly connected, and the upper pressure plate 13 and the lower pressure plate 10 are fastened together by bolts on both sides.

[0023] In summary, the implementation of this utility model requires that, during installation, the fixing base 14 of the fixing component 2 and the guide component 1 be fixed to the top and wall of the aeration tank respectively using anchors. Subsequently, the frame structure formed by the assembled air supply pipe 3, air distribution pipe 4, air outlet pipe 5, aeration disc 6, safety net 7, and limiting rod 8 is placed into the aeration tank, ensuring that the limiting rod 8 is positioned between the upper pressure plate 13 and the lower pressure plate 10 of the guide component 1 on both sides of the tank wall. Since the centers of the upper pressure plate 13 and the lower pressure plate 10 are designed to be arc-shaped, the frame structure can slide down to the bottom of the tank using the limiting rod 8 along the groove between the upper pressure plate 13 and the lower pressure plate 10. Finally, the installation and fixing are completed by tightening the bolts on both sides of the fixing component 2 and the upper and lower pressure plates 13 and 10 of the guide component 1.

[0024] During operation, the air pump delivers air into the air supply pipe 3, and the air is sprayed out from the micro-holes of the aeration disc 6 through the air distribution pipe 4 and the air outlet pipe 5 to achieve aeration treatment of sewage.

[0025] When maintenance is required, first remove the upper pressure plate 13 of the top fixing component 2 of the aeration tank, release the end of the limit rod 8, and then loosen the bolts on both sides of the guide plate 1. Activate the working switch of the externally operated electric three-way reversing valve 9 to change the air outlet direction, connecting the air supply pipe 3 to the air delivery pipe 11. Simultaneously, the air pump inflates the air supply pipe 3, which in turn inflates the air delivery pipe 11 into the bladder 12. After the bladder 12 inflates, its buoyancy lifts the entire frame structure above the sewage surface. Then, retighten the bolts on both sides of the upper pressure plate 13 and lower pressure plate 10 of the guide plate 1, and lock the limit rod 8 to ensure stability. At this time, maintenance personnel can safely step on the safety net 7 to perform necessary maintenance on the aeration disc 6.
