A degreasing and skimming device for sewage treatment plants

Abstract

The invention discloses a degreasing and skimming device for a sewage treatment plant. The device comprises a slag collecting floating cover, a floating net, a driving contact ring, an oil removing rotating ring, a machine frame, an oil slag storage bin, a smart waterproof walking seat and an internal oil slag treatment device, the slag collecting floating cover is arranged at the upper end of themachine frame, the machine frame is located at the center of the upper end of the slag collecting floating cover, the floating net is embedded in the upper end of the machine frame, an soil scrapingstructure frame is stored in a machine frame internal bin when not used, the damage rate of the oil scraping structure frame is greatly reduced through isolation, the oil scraping structure frame canscrape a large area of sludge at a time, transmission is achieved by utilizing the device to touch a pool internal wall, the sludge on the pool internal wall is cleaned, during the transmission process, an auxiliary hook rod is swung under the action of the rotation of an auxiliary transmission gear, the intermittent blocking of the auxiliary transmission gear is achieved, so that the rotation ofa circular tooth plate becomes slower, the oil removing rotating ring is driven to rotate slowly, oil slag removal actions are light and slow, and the cleaning is more thorough.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an oil removal and scum removal device used in sewage treatment plants. Background technique [0002] At present, oil slicks in the steel cutting process, animal and vegetable oils in catering and domestic sewage, and grease scum in petroleum enterprise sewage are all organic pollutants that are difficult to remove and degrade, requiring special hydrolysis acidification tanks, BAF filters, demulsification devices, Large-scale professional equipment such as air flotation pools are used for processing, but each of the above-mentioned facilities covers a large area, high engineering cost, and requires a large amount of labor. If it involves standard upgrading and renovation, the entire treatment system will be required for the renovation process. Long-term outage is quite difficult for the established sewage treatment facilities. At present, there is no land-saving nested equipment t...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the deficiencies of the prior art and provide an oil removal and scum removal device for sewage treatment plants to solve the problem of incomplete cleaning of oil residues, inability to effectively collect oil residues, and untargetable dirt on the inner wall of the pool Cleaning. Efficient cleaning cannot be achieved for sewage tanks with large sludge production, and the cleaning effect for thicker inner walls of the tanks is poor, resulting in difficulties in subsequent sludge accumulation, serious wear and tear in the tanks, and failure of normal operation of sewage treatment equipment.
