A filter device for aviation fuel oil production

Abstract

A filter device for aviation fuel oil production. The invention belongs to the field of fuel oil filter devices. Connected through the inner holes of the annular partition, several series of filter holes are evenly opened on the outer periphery of the filter cartridge, and the scraper is installed movable in the filter cartridge, and several through-holes of the sinker are evenly opened on the scraper, and the through-holes of the sinker are hinged and installed by torsion springs The filter screen plate and the tank body are provided with an oil inlet and an oil outlet, and the corresponding rolling gears on the periphery of the filter cartridge are respectively fixedly installed with bar-shaped racks, and the rolling gears mesh with the corresponding bar-shaped racks respectively. The invention can use the ejector rod to block the filter hole when scraping the filter cartridge, so that the inner wall of the filter cartridge can be scraped and cleaned during the filtering process, and at the same time, the scraped filtrate can be gathered in the filter cartridge Top, reduce secondary pollution of unfiltered fuel oil by filtrate.

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 ...
