Self-adjusted scraper plate type backwash filter for ocean nuclear power platform

Abstract

The invention relates to a self-adjusted scraper plate type backwash filter for an ocean nuclear power platform. The filter comprises a cylinder body, an output hole, an input hole and a blow-down hole are respectively formed in the upper part, the lower part and the bottom of the cylinder body. The self-adjusted scraper plate type backwash filter is characterized in that a repairing door is formed in the cylinder body; a rotating filtering net rack is arranged inside the cylinder body; detachable filtering net plates are connected with the periphery of the filtering net rack; the filtering net plates and the filtering net rack form a prism-shape filtering net; the cylinder body is internally provided with a threaded rod which is arranged in a same axis with the cylinder body; more than one self-adjusted scraper plates of which the shapes correspond to that of the filtering net are in spiral cooperation with the threaded rod; scraping strips on the self-adjusted scraper plates are matched with the inner wall of the filtering net plates; a driving device is arranged on an upper sealing cover; the upper end of the threaded rod penetrates through the upper sealing cover and is linked with the driving device. The filter is small in top space, low in operation noise, good in conformity, free of excessive abrasion, long in service life, convenient to repair, simple and rapid and time and material saving.

Description

technical field [0001] The invention relates to a filter, in particular to a self-adjusting scraper type backwash filter for an ocean nuclear power platform. Background technique [0002] The marine nuclear power platform is a combination of marine engineering and civil nuclear power technology. It adopts the mooring ship type and is responsible for offshore power supply and water supply. The marine nuclear power platform includes lubricating oil system, regulating oil system, circulating water system and sewage system, etc. The wear and tear of the lubricating oil system will produce dust, and the lubricating oil working at high temperature will cause part of the oil to crack and deteriorate to precipitate colloidal substances. Impurities in the lubricating oil affect the lubrication effect, reduce the flow performance, and have adverse effects on the oil pump and the operating equipment. During the water circulation process of the circulating water system, suspended matt...

Problems solved by technology

Impurities in the lubricating oil affect the lubrication effect, reduce the flow performance, and have adverse effects on the oil pump and the operating equipment

During the water circulation process of the circulating water system, suspended matter will be produced, which will be brought into the marine organisms, causing problems such as corrosion, blockage and marine organisms adhesion to the circulating water system equipment.

The suspended solids carried by the sewage will have an adverse effect on the purification efficiency and equipment life of the subsequent purification treatment device

The above problems are often solved by arranging self-cleaning filters in the corresponding systems. The existing self-cleaning filters mainly include suction type, brush type, arm type, and scraper type. Among them, the scraper type self-cleaning filter Compared with other types, the cleaning is thorough, but its lifting rod structure requires a lot of space on the top of the filter

In addition, the noise generated is large; the fixed size scraper, scraper and scraper are easy to wear the filter screen; when maintaining and replacing the filter screen, the entire filter needs to be disassembled
