Foam scraping equipment for horizontal flow type oil separation pool, and working method thereof

Abstract

The invention discloses foam scraping equipment for a horizontal flow type oil separation pool. The foam scraping equipment comprises a foam scraping mechanism, a filtering mechanism and a liner mechanism, wherein the foam scraping mechanism comprises a driving motor, a first belt wheel, an oil discharging plate, a foam scraping belt, a second belt wheel, a connecting rod, a foam scraping plate and a fixing bracket, the filtering mechanism comprises a filtering box shell, an oil inlet, a gas inlet pipe, an oil outlet, a supporting column, a fixing plate and a communicating pipe, and the linermechanism comprises a first conduction pipe, a second conduction pipe, a fixing disc, a moving sliding block and a filtering sieve. The invention further discloses a working method of the foam scraping equipment. According to the present invention, oil foams are respectively scraped by the oil discharging plate and the foam scraping plate so as to improve the foam scraping effect; and after the filtering is finished, the second conduction pipe is driven by the moving sliding block to move to the interior of the first conduction pipe, such that the oil foam remaining in the first conduction pipe can be discharged so as to prevent the oil foam residue.

Description

technical field [0001] The invention relates to a foam scraping device, in particular to a foam scraping device for an advection grease trap and a working method thereof. Background technique [0002] The grease trap is a treatment structure that uses the difference in specific gravity between oil and water to separate and remove suspended oil with large particles in sewage. Petroleum industry and petrochemical industry discharge waste water containing a large amount of oil in the production process; coal coking and gasification industry discharge waste water containing high concentration of tar; wool spinning industry and meat industry discharge waste water containing more oil. If these oily waste water is discharged into the water, it will cause pollution, and the irrigation of farmland will block the soil pores, which will harm the growth of crops. Essential in the grease trap is the oil scraper. [0003] Chinese invention patent CN107715515A discloses a new type of oil...
