Description

[Detailed Description of the Invention] The present invention relates to an odor-proof lid that is useful for environmental conservation and labor saving in sewage treatment plants.

Traditionally, sewage and rainwater generated in households, factories, etc. is collected individually as appropriate, then led to sewage pipes, and then passed through a pump station and sent to a sewage treatment plant in order to treat the sewage into clean water. The sewage sent to this treatment plant first enters the settling basin, and as it flows slowly through the settling basin, it settles to the bottom and removes this sediment. The sewage that has settled to the bottom of the settling basin is then sent to the original sewage treatment plant by a pump after bulky waste is removed.The sediment that has settled to the bottom of the settling basin is transferred to a bucket. It is designed to be removed to the surface by means of However, due to the nature of this settling basin, a strong odor is emitted from the liquid level, so in order to preserve the environment around the sewage treatment plant, it is necessary to install odor control equipment and a cover to cover the top of the settling basin. There is.

Conventional deodorizing covers of this type are often of the pontoon type, which are made up of multiple sheets, but not only are they not useful as complete odor-proofing covers, but they also have a negative impact on the settling basin. There is also the inconvenience that the lid must be manually removed or moved when carrying out work such as scraping up sediment that has accumulated on the bottom. In other words, in order to carry out this work, a large amount of manpower and a large amount of time are required, and since these works are currently being carried out through outsourcing, a large amount of expense is required. I needed it.

Therefore, the present invention aims to provide an odor-proof lid for sewage treatment plants that can eliminate these wasteful manpower and time consumption, completely prevent odor, and can open and close automatically. That is the purpose.

In the present invention, in order to achieve this objective, a pair of peripheral edge members are installed horizontally above the liquid level of the settling basin at a certain distance from the liquid level, and on top of these edge members are the edges of the settling basin. A plurality of panels each having a rectangular planar profile are supported by their respective edges and are arranged with opposite sides closely spaced so as to cover the entire surface, and each adjacent panel has opposite sides. These panels are pivotally connected to each other by hinges along the sides of the settling basin, and the panels at one end adjacent to the containment platform formed at the top of one end wall of the settling basin are When the panel is erected by a drive source such as hydraulic pressure so that its plane is perpendicular to the surrounding edging, each adjacent panel hinged to the panel will have its edges resting on the edging. It is characterized in that it can be folded up into a floppy shape on a storage platform by moving in sequence, and the liquid level of the settling basin can be released.

Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 8 of the accompanying drawings showing embodiments thereof.
