[0002] At present, some rural areas adopt centralized water supply, which is centralized from water sources and delivered to users through water distribution pipes. 3 Small water supply projects with a population of less than 10,000 or less than 10,000 need to use a clear water tank. The source water is treated by flocculation, oxidation, adsorption, ultrafiltration and other water purification processes and stored in the clear water tank for use as domestic drinking water, and no disinfectant is added to the factory water. Usually, a manhole is set in the clear water tank for inspection and maintenance of the clear water tank, and a ventilation device is set on the manhole to balance the air pressure inside the clear water tank with the outside. Such manholes and ventilation devices are numerous and widely used in rural China. However, they are limited by the level of grassroots technical management. Usually, only simple ventilation holes are used, and no filter is set. Such a structure cannot effectively prevent dust, microorganisms, small insects, particulate matter in the air, etc. from entering the clear water tank, and many bacteria are attached to fine dust, which can easily cause secondary pollution to the water in the clear water tank. Such manholes and ventilation devices usually do not take any measures to prevent and control secondary pollution, resulting in the risk of excessive microorganisms in the water delivered to users.

Changes or adjustments to their relative relationships should be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0029] like Figure 1-7 As shown, this embodiment provides a vent disinfection device, including a vent pipe 1, a first bottom plate 2, a first ring plate 3, a top plate 4, a second ring plate 5, a second bottom plate 6 and a third ring plate 7; wherein the ring plate refers to a cylinder with open upper and lower ends, and the bottom plate is a flat plate. The lumen of the vent pipe 1 is a lower airway 18, a screen 8 is provided in the upper end of the vent pipe 1, the first bottom plate 2 is arranged on the upper peripheral side of the vent pipe 1, the first ring plate 3 is arranged on the edge of the upper surface of the first bottom plate 2, the top plate 4 is arranged on the top of the first ring plate 3, the second ring plate 5 is arranged on the upper surface of the first bottom plate 2, a spacing is provided between the top of the second ring plate 5 and the top plate 4, and a spacing is provided between the second ring plate 5 and the first ring plate 3 to form an external airway 15, and the first bottom plate 2 is at the bottom of the external airway 15. A densely distributed first ventilation hole 9 is arranged, a second bottom plate 6 is arranged on the peripheral side of the ventilation pipe 1 and is located above the first bottom plate 2, the second bottom plate 6 is provided with a densely distributed second ventilation hole 10, a third ring plate 7 is arranged on the edge of the upper surface of the second bottom plate 6, a spacing is provided between the third ring plate 7 and the second ring plate 5, and a spacing is provided between the second bottom plate 6 and the first bottom plate 2 to form a medicine cavity 16 for containing calcium hypochlorite tablets, the top of the third ring plate 7 is sealed with the lower side of the top plate 4, and the space inside the third ring plate 7 is an upper air duct 17.

[0030] When the water level in the clean water tank drops, the internal air pressure decreases, and the external air enters the clean water tank through the vent disinfection device of the utility model to balance the air pressure. The air first enters the external air duct 15, and the entrance of the external air duct 15 (multiple first air vents 9) is downward, which can effectively prevent small animals, fallen leaves, etc. from entering. The upper end of the external air duct is connected to the upper end of the medicine cavity 16, and the medicine cavity 16 is filled with calcium hypochlorite tablets. The tablets will generate calcium carbonate and hypochlorous acid when they come into contact with carbon dioxide and water in the air. Hypochlorous acid is oxidizing and can destroy protein structure, kill microorganisms, small insects, etc.; in addition, the tablets can also block some dust in the air. The air passes through the medicine cavity 16 from top to bottom, and enters the upper air duct 17 from the bottom of the medicine cavity 16 after being disinfected by the tablets. There is a layer of fine screen 8 between the upper air duct 17 and the lower air duct 18, which further blocks fine dust from entering the clean water tank. After further filtering through the screen 8, the air from the upper air duct 17 enters the lower air duct 18 and then enters the clean water tank. In addition to being applied to the manhole cover 19, the vent disinfection device of the utility model can also be used for ventilation disinfection of water tanks, etc., and the lower end of the vent pipe 1 can be directly connected to the vent of the equipment.

Specifically, a second flange 12 is provided on the outer periphery of the lower edge of the first ring plate 3, and the second flange 12 is provided with a plurality of second bolt through holes, and a plurality of third bolt through holes are provided on the edge of the first bottom plate 2, and the plurality of third bolt through holes are arranged one by one with the plurality of second bolt through holes, and a second sealing structure such as a sealing ring, a sealing gasket, etc. is provided between the second flange 12 and the first bottom plate 2, and the second flange 12 is connected to the first bottom plate 2 by bolts.

[0033] In this embodiment, the top plate 4 and the first ring plate 3 are formed as an integral structure, such as integrally stamped, which can not only ensure the sealing of the two, but also improve production efficiency and reduce production costs.

[0034] In this embodiment, a third sealing structure 14 , such as a sealing ring, a sealing gasket, etc., is provided on the top of the third ring plate 7 . The third sealing structure 14 seals the gap between the top of the third ring plate 7 and the top plate 4 .

[0035] In this embodiment, the third ring plate 7 and the second bottom plate 6 are formed as an integral structure (meaning they cannot be disassembled), such as by welding, which ensures the sealing effect while eliminating the need for flanges and other structures.

[0036] In this embodiment, the second bottom plate 6 is detachable and sealed and fixed to the top of the vent pipe 1. On the one hand, the detachable connection form enables the second bottom plate 6 and the vent pipe 1 to be processed separately as two parts, reducing the processing difficulty; on the other hand, the sealing and fixing can prevent dust that is not filtered from entering the lower vent 18 with the air from here. Specifically, a third flange 13 is provided at the inner edge of the top of the vent pipe 1, and the third flange 13 is provided with a plurality of second threaded holes. A second through hole is provided in the middle of the second bottom plate 6, and a plurality of fourth bolt through holes are provided at the edge of the second through hole. The plurality of fourth bolt through holes are arranged one-to-one with the plurality of second threaded holes. A fourth sealing structure, such as a sealing ring, a sealing gasket, etc., is provided between the second bottom plate 6 and the third flange 13. The second bottom plate 6 and the third flange 13 are connected by bolts.

[0037] In this embodiment, the screen 8 is made of unmodified material to prevent rust from being affected by water vapor for a long time.

[0038] In this embodiment, the cover body formed by the first ring plate 3 and the top plate 4 is a stainless steel cover body to avoid aging and cracking caused by long-term sunlight exposure, and the surface of the cover body is coated with anti-corrosion paint.

[0039] In this embodiment, the second ring plate 5, the third ring plate 7 and the second bottom plate 6 are made of stainless steel, polytetrafluoroethylene and other corrosion-resistant plastics. When they are made of stainless steel, anti-corrosion paint is coated on the surface.
