Embodiment 1

[0033] refer to Figure 1-5 , a kind of degreasing and skimming device used in sewage treatment plants, comprising a sewage pool 14, a first screw 11 is arranged in the sewage pool 14, two moving plates 1 are threaded on the first screw 11, and the two moving plates 1 are respectively provided with internal threads in opposite directions, and both ends of the moving plate 1 are offset against the inner side wall of the sewage pool 14. The two moving plates 1 can be driven by the first screw 11 to approach each other, and then the upper surface of the sewage The oil stains are gathered together. After the oil stains are picked up, the two moving plates 1 are far away from each other and offset against the side wall of the sewage tank 14, which is convenient for picking up the oil stains next time. The bottom end of the moving plate 1 is fixed with a shock absorbing device. Increase the shock resistance of the moving plate 1 to avoid hard foreign objects at the bottom of the sew...

Abstract

The invention discloses an oil removing and slag skimming device for a sewage treatment plant. The device comprises a sewage tank; a first screw rod is arranged in the sewage tank; two moving plates sleeve the first screw rod in a threaded manner; internal threads with opposite directions are respectively arranged in the two moving plates; two ends of each moving plate are abutted against inner side walls of the sewage tank; a damping device is fixed at the bottom end of one moving plate; a moving device is arranged between the damping device and the inner bottom end of the sewage tank; a conveying belt is arranged between the two moving plates; scrapers are arranged on the conveying belt; a second rotating shaft is fixedly sleeved by one side, far away from the first screw rod, of the conveying belt; and the second rotating shaft is rotationally provided with an object table. The oil removing and skimming device for the sewage treatment plant has a novel structure, and can conveniently scoop up oil stains when in use. Meanwhile, efficiency is high, and a large amount of manpower can be saved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to an oil removal and scum removal device used in sewage treatment plants. Background technique [0002] The sewage mainly includes domestic sewage and industrial wastewater. The main pollutants in the sewage include pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. At the same time, after the sewage flows into the sewage treatment plant, a large amount of oil stains accumulate on the upper surface of the sewage. It is difficult to remove and degrade, so it needs to be fished out. At present, the oil stains are mostly scraped up manually. [0003] The current method of manually scraping up oil stains is not easy to clean and collect the oil stains in the sewage, which requires a lot of manpower and is inefficient. At the same time, the effect of collecting oil stains is not obvious, and the oil stains cannot be completely remo...
