Abstract

The invention discloses an oil scraping device for wastewater treatment. The device comprises a device shell, a motor, a driving roll, a driven roll, a driving belt, an oil scraping belt, an oil scraper and a bracket, wherein the motor, the driving roll and the driving belt are arranged on the device shell; the motor is connected with the driving roll through the driving belt; the driving roll is connected with the driven roll through the oil scraping belt; the device shell is mounted at the upper part of the bracket; the driven roll is fixed at the lower part of the bracket; the oil scraper comprises two scraping blades positioned on the two sides of the oil scraping belt; a knife rest is correspondingly fixed at the bottom of each scraping blade; a distance regulating mechanism is arranged between the two knife rests. The device overcomes the defects that the oil scraping belt and the scraping blades need replacing frequently, and oil contamination is collected not thoroughly.

Description

technical field [0001] The invention belongs to the field of sewage treatment devices, and in particular relates to an oil scraping device for sewage treatment. Background technique [0002] At present, most of the sewage treatment of new refineries in my country adopts grease traps, flotation tanks and aeration tanks. The key equipment of this sewage treatment process is: oil scraper and mud scraper, foam scraper and aeration machinery. There are two methods of oil separation, one is inclined plate oil separation, and the other is advection oil separation, which mainly removes oil droplets with a particle size of 100-105 microns or more and removes sludge. The operation of the advection type grease trap is relatively stable and reliable. Domestic transportation has mature experience. Timely oil collection and regular mud discharge are powerful measures to ensure the normal operation of the advection type grease trap. Taking an oil refinery with an annual crude oil process...
