[0002] Shanghai waterworks has vigorously promoted the transformation of advanced treatment processes to improve the urban water treatment effect and significantly improve the drinking water quality. Among them, the advanced treatment process of ozone-activated carbon combination is the most widely used. Adding ozone can achieve disinfection and sterilization. When ozone combines with granular activated carbon, various organic matters can be effectively removed after the conventional water purification process.

[0003] In order to quickly and evenly distribute the ozone gas flow in water and fully contact with water to dissolve ozone in water to the maximum extent, a gas-liquid contact reaction device (dispersed gas) is required. The microporous aeration disk is one of the most widely used in China at present.

[0004] Traditional ozone aeration disks are usually fixed to the aeration pipeline with metal bolts. To maintain good aeration effect, the aeration disks need to be disassembled and cleaned regularly. However, traditional ozone aeration disks are prone to rust and difficult disassembly after long-term use. This not only affects the service life and working efficiency of the aeration disks, but also increases the maintenance cost. Therefore, in view of the above problems, it is necessary to improve the structure of the existing ozone aeration disk. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an improved ozone aeration disk to solve at least one of the above problems, so as to solve the problems that the ozone aeration disk is prone to rust and difficult disassembly after long-term use in the prior art. This solution realizes the characteristics of easy disassembly and maintenance, and at the same time extends the service life.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0015] Preferably, the length of the extended bolt is 70 - 120 mm, and a part of the head with a length of 20 mm - 1 / 3 of the length is a smooth surface without threads.

[0016] Preferably, through holes are symmetrically arranged on the smooth surface without threads.

[0017] Preferably, the structure of the connecting piece is a convex shape, and the large-diameter side faces the chassis.

[0018] Preferably, the large internal thread is arranged on the large-diameter part of the connecting piece for threaded connection with the chassis, and the small internal thread is arranged on the small-diameter part of the connecting piece for threaded connection with the extended bolt.

[0019] Preferably, the inner diameter of the large internal thread is larger than the inner diameter of the small internal thread.

[0020] Preferably, the connecting piece is threadedly connected to the air distribution pipe through the external connecting thread on the outside.

Specific implementation mode

[0031] The present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] As Figure 1 shown, it is an existing traditional aeration disc, which is composed of a disc body 1', a chassis 2', and a bolt 3'. The bolt 3' passes through the disc body 1', and its external thread is fixed to the internal thread of the chassis 2'. The external thread of the chassis 2' is fitted and fixed with the internal thread of the air distribution pipeline interface. Among them, the material of the aeration disc bolt 3' is 316 stainless steel, and the material of the chassis 2' is also 316 stainless steel. Under the impact and immersion of ozone gas for a long time, the same material stainless steel threads are prone to jamming. When it is necessary to disassemble the ozone aeration disc for cleaning and maintenance, due to the use of the bolt 3' and the chassis 2' made of the same 316 stainless steel material, it is difficult to disassemble the above-mentioned internal and external thread fitting parts. The aeration effect of the ozone aeration disc without disassembly and cleaning decreases, the ozone dosing efficiency decreases, and the treatment effect of the advanced treatment process is affected. If it is disassembled violently, it is easy to damage the aeration disc, reduce the service life of the aeration disc, and increase the maintenance cost.

[0033] Embodiment 1

[0034] An improved ozone aeration disc, as Figure 2-6 shown, includes a disc body 1 and a chassis 2, and also includes a lengthened bolt 3 and a connecting piece 4;

[0035] The lengthened bolt 3 penetrates through the disc body 1 and is arranged with the chassis 2, and the external thread 31 at the tail of the lengthened bolt 3 is threadedly connected with the small internal thread 41 of the connecting piece 4;

[0036] The described chassis 2 is threadedly connected to the large internal thread 42 of the connecting member 4 through the external thread 21 of the chassis;

[0037] The described extended bolt 3 and the described connecting member 4 are made of different materials;

[0038] The described improved ozone aeration disk is assembled on the air distribution pipeline through the connecting member 4.

[0039] Furthermore, in this embodiment:

[0040] An improved ozone aeration disk is composed of a disk body 1, a chassis 2, an extended bolt 3, and a connecting member 4:

[0041] The described improved ozone aeration disk is installed on the air distribution pipeline through the connecting member 4;

[0042] The disk body 1 and the chassis 2 are connected by an extended bolt 3;

[0043] The described extended bolt 3 passes through the chassis 2 and is engaged with the small internal thread 41 inside the connecting member 4 through the external thread 31 of the bolt;

[0044] The described chassis 2 is engaged with the large internal thread 42 inside the connecting member 4 through the external thread 21 of the chassis;

[0045] The connecting external thread 43 of the described connecting member 4 is engaged with the internal thread of the interface of the air distribution pipeline, thereby fixing the ozone aeration disk on the air distribution pipeline.

[0046] For this improved ozone aeration disk, first, bolts made of more corrosion-resistant 316L stainless steel are selected. At the same time, the traditional bolts are lengthened to form the extended bolt 3. The internal thread of the chassis 2 is polished smoothly to form the inner hole 5 of the chassis 2, avoiding the engagement of the extended bolt 3 with it. A new connecting member 4 made of 316 stainless steel is added. The disk body 1, the chassis 2, and the extended bolt 3 are combined through the connecting member 4, and the ozone aeration disk is fixed on the air distribution pipeline; when disassembling the ozone aeration disk for cleaning and maintenance, since the extended bolt 3 and the connecting member 4 are made of different stainless steel materials, the situation where it is difficult to disassemble at the inner and outer thread engagement part will not occur, which is more convenient and fast, extends the service life of the accessories, and reduces the maintenance cost.

[0047] Preferably, the material of the described extended bolt 3 is changed from 316 stainless steel to 316L stainless steel. The Mo content in 316L stainless steel enables this steel type to have excellent corrosion resistance. Therefore, this type of stainless steel is widely used in industrial fields with strong corrosion environments; the change of the material also effectively avoids the situation where it is difficult to disassemble at the engagement part of the extended bolt 3 and the connecting member 4, resulting in the inability to effectively clean the ozone aeration disk;

[0048] Preferably, the diameter of the extended bolt 3 is 10 mm and its length is increased to 74 mm. Among them, 25 mm of the bolt head is a smooth surface without threads. This design enables the bolt head to directly pass through the inner hole 5 of the chassis 2, and the smooth surface of the bolt head contacts the smooth inner hole 5 of the chassis 2, eliminating the original jamming phenomenon inside the chassis 2; the length of the extended bolt 3 is increased compared with the traditional bolt to meet different installation depth requirements;

[0049] Preferably, on the smooth surface of the extended bolt 3, symmetrically arranged openings are provided. These openings are used for the outlet of ozone gas.

[0050] Preferably, the inner hole 5 of the chassis 2 is formed by polishing the internal threads of the chassis 2 smooth. The elimination of the internal threads reduces the friction between the chassis 2 and the extended bolt 3 during the disassembly process, making the disassembly of the aeration disc smoother;

[0051] Preferably, a new connector 4 is added at the connection between the aeration disc and the pipeline. The connector 4 is made of 316 stainless steel and is convex. The upper and lower parts respectively include a small internal thread 41 and a large internal thread 42; the cooperation of two different materials reduces the resistance and friction between the same materials;

[0052] Preferably, the small internal thread 41 of the connector 4 is connected to the external thread 31 at the bottom of the extended bolt 3, and the large internal thread 42 of the connector 4 is connected to the external thread 21 of the chassis, effectively serially fixing the disc body 1 and the chassis 2, enhancing the sealing performance, preventing gas leakage, and ensuring good airtightness, stability and corrosion resistance;

[0053] Preferably, the connecting external thread 43 of the connector 4 is fitted with the internal thread of the air distribution pipeline interface, making the installation between the aeration disc and the pipeline more stable, and the disassembly through the connector 4 is also easier to operate.

[0054] In summary, the improved ozone aeration disc proposed in this solution has the characteristics of being easy to disassemble, assemble and maintain; at the same time, it also reduces the rusting phenomenon caused by material problems, extends the service life, has the characteristic of strong durability, and significantly improves the efficiency and reliability of the water treatment process.

[0055] The above description of the embodiments is for the convenience of those of ordinary skill in the art to understand and use the utility model. Those skilled in the art can obviously make various modifications to these embodiments easily and apply the general principles described herein to other embodiments without creative labor.
