Description

TECHNICAL FIELD

[0001] The utility model relates to sewage treatment technology technical field especially relates to a sewage well stinkproof air -tight seal cover. BACKGROUND

[0002] Sewage treatment is the process that sewage is purified before being discharged into other water areas or being used again, and the polluted water is purified by physical and chemical methods, so that the purified water can achieve the effect of repeated use. Sewage treatment is widely used in construction, agriculture, transportation, environmental protection, urban landscape, medical treatment, catering and other fields, and is a technology that people cannot do without in their daily life. When sewage is treated, a deodorizing cover needs to be installed on the top of the sewage tank to prevent the stench and marsh gas contained in the sewage from being discharged to pollute the surrounding air. However, the traditional seal cover still has some defects, such as the inability to adjust the height and size.

[0003] A seal cover for a new type of sewage tank is disclosed in Chinese Patent No. CN 209891371 U, which comprises a glass steel cover. The glass steel covers are butted to form a seal cover for the sewage tank. The end panels of the seal cover are provided with end panels for butting the glass steel covers. The glass steel covers are of the same size. The cross section of the glass steel cover is arc-shaped. The two end faces of the glass steel cover are provided with protrusions and grooves. The protrusions on one end face of the glass steel cover correspond to the grooves on the other end face. The grooves on one end face of the glass steel cover correspond to the protrusions on the other end face. The design of this patent is innovative, simple in structure, beautiful in appearance, convenient to assemble and disassemble, has high structural strength, can be produced on a large scale in a modular manner, is convenient to install on the surface of the sewage tank, and has good market prospects.

[0004] However, the above-mentioned patent does not have the function of adjusting the height. The height of the seal cover needs to be adjusted according to the height of the wellhead of some sewage wells, so that the height of the seal cover can adapt to the height of the wellhead, thereby achieving full coverage of the wellhead and preventing stench from being directly discharged. The adjustability is reduced. Long-term sealing can cause excessive air pressure in the seal cover, and easily cause marsh gas to accumulate. When the air pressure is too high, the seal cover will be squeezed, causing damage to the seal cover, and thus causing stench and marsh gas to flow out through the damaged hole into the air, thereby polluting the air and causing pollution to the surrounding environment. A large amount of marsh gas accumulation can easily cause safety hazards, thereby reducing safety. UTILITY MODEL CONTENTS
