Filtering device for aviation fuel oil production

Abstract

The invention discloses a filtering device for aviation fuel oil production and belongs to the field of fuel oil filtering devices. The filtering device comprises a tank body; an annular partition plate is fixedly mounted in the tank body, a filtering cylinder is fixedly mounted below the annular partition plate, the top of the tank body is communicated with the interior of the filtering cylinder through an inner hole of the annular partition plate, and a plurality of rows of filtering holes are uniformly formed in the periphery of the filtering cylinder. A scraping plate is movably installed in the filter cartridge, a plurality of sinking groove through holes are evenly formed in the scraping plate, a filter screen plate is installed in the sinking groove through holes through torsion springs in a hinged mode, an oil inlet and an oil outlet are formed in the tank body, strip-shaped racks are fixedly installed on the periphery of the filter cartridge corresponding to the rolling gears respectively, and the rolling gears are meshed and matched with the corresponding strip-shaped racks respectively. According to the invention, when the filter cartridge is scraped, the ejector rod is used for blocking the filter hole, so the inner wall of the filter cartridge can be conveniently scraped and cleaned in the filtering process, and meanwhile, scraped filtered substances can be gathered at the top of the filter cartridge, so secondary pollution of the filtered substances to unfiltered fuel oil is reduced.

Description

technical field [0001] The invention belongs to the field of fuel oil filtering devices, in particular to a filtering device for aviation fuel oil production. Background technique [0002] During fuel oil production, there will be a lot of scum, sediment or other impurities inside, which need to be filtered. During the fuel oil filtration process, the filter cartridge needs to be cleaned continuously to avoid clogging of the filter holes. Generally, scrapers are used to scrape them off. However, when the filter plate is scraped during use, a part of the filtrate that is difficult to pass through the filter hole will be squeezed out of the filter hole, and the filtered fuel oil will be polluted again. , can not meet the actual needs, so we invented a filter device for aviation fuel oil production. Contents of the invention [0003] The invention provides a filter device for aviation fuel oil production to solve the defects in the prior art. [0004] The present invention ...
