Description

Sewage treatment oil scraping device with adjustable scraper angle

technical field

The utility model belongs to the field of sewage treatment devices, in particular to an oil scraping device for sewage treatment with an adjustable scraper angle.

Background technique

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 processing capacity of 2.05 million tons as an example, it can recover 3,000-5,000 tons of waste oil and 1,000-2,000 tons of sludge a year. Oil separation and mud removal have basically been mechanized in my country. Commonly used oil scraping and mud scraping machines are chain type, winch traction type, endless rope traction type; driving type, single scraper type, etc. There are new types of oil scraping and mud scraping machines abroad, including driving type and linkage type.

Most of these methods have the disadvantages of complex transmission parts, large steel consumption, short service life of working parts, incomplete collection of oil pollution, and strict construction requirements.
