Closed air collecting arch-shaped cover plate of sewage pond

Abstract

The invention provides a closed air collecting arch-shaped cover plate of a sewage pond. The closed air collecting arch-shaped cover plate comprises a cover body with an arc-shaped section; pond body connecting flanges are bent at two long sides of the cover body; cover plate connecting flanges are bent at two short sides of the cover body; concave reinforcing strips with trapezoidal sections are pressed at intervals on the cover body; the cover plate is of an arc-shaped structure and formed by a single stainless steel arch-shaped plate. Compared with the prior art, the closed air collecting arch-shaped cover plate is manufactured from stainless steel and is simple in structure. The closed air collecting arch-shaped cover plate has the advantages of being high in strength, resistant to corrosion, long in service life, high in safety, free of special corrosion preventing treatment, and convenient to manufacture and mount; different arch height can be set according to the width of a pond body; therefore, the problem that the corrosion resistance, the ageing resistance and the strength of the cover plate of the sewage pond are reduced as time goes on can be effectively solved; the manufacturing and mounting are convenient; the manufacturing cost is small; secondary pollution is avoided.

Description

technical field [0001] The invention belongs to the field of making an arched cover plate of a sewage pool, and in particular relates to a stainless steel cover plate. Background technique [0002] With the development of the economy and the aggravation of smog weather, more and more attention has been paid to environmental protection, and the state's efforts to govern the environment have also been strengthened year by year. During the treatment process of the sewage treatment plant, harmful gases are directly released into the air, which has an impact on the environment and human health. At present, the sewage treatment tank adopts the glass fiber reinforced plastic cover plate to collect the sewage pool secretly. Since the glass fiber reinforced plastic cover plate is easy to age under the sunlight, the strength of the cover plate decreases year by year with the prolongation of the service life, and the service life is short. And when the cover plate reaches After the se...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects and deficiencies of the existing glass fiber reinforced plastic cover plate of the sewage pool, which are easy to age, have poor corrosion resistance and troublesome waste treatment after scrapping, and provide a kind of anti-corrosion, high strength, long service life and no waste after scrapping. Sewage tank gas tight collection arched cover that will pollute the environment
