Anti-scaling suction coarse water filter for ship

Abstract

The invention discloses a ship anti-scaling suction coarse water filter, and relates to the technical field of ships, the ship anti-scaling suction coarse water filter comprises a filter cartridge, a water inlet pipe and a water outlet pipe, a sliding pipe is arranged in the water inlet pipe, the sliding pipe is provided with a first filter layer, an inner filter chamber is provided with a second filter layer, an outer filter chamber is fixedly provided with a connecting pipe, the connecting pipe is provided with a third filter layer, and the first filter layer is connected with a rotating rod; the rotating rod is provided with a first brush plate and a retracting column, a retracting groove is formed in the retracting column, an elastic pad is arranged in the retracting groove, a second brush plate is slidably arranged in the retracting groove, the second brush plate is connected with a rotating shaft, the rotating shaft is provided with a first scraper, the rotating shaft is provided with a second scraper, the rotating rod is provided with a propeller, and the rotating rod is provided with a third brush plate. And the third brush plate is provided with a third scraping plate. A plurality of filtering layers are arranged, so that coarse water is more thoroughly filtered in a layered manner, a brush plate is driven to rotate to clean the inner walls of the filtering layers while water flows, cleaned dirt is scraped off and accumulated to a designated position, and the device is convenient to clean and suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of ships, and in particular relates to an anti-scaling and suction coarse water filter for ships. Background technique [0002] Recently, with the rapid development of modern industry, the use of coarse suction water filters has become more and more widespread. The suction coarse water filter is mainly used in the water balance system of the ship's ballast tank. The traditional coarse water filter is designed and manufactured according to the marine industry standard, and the adaptable medium is seawater or freshwater. The common problem is that impurities are easy to accumulate in the filter and it is difficult to clean, and the existing suction coarse water filter has poor filtering effect during use, and the filter element or filter screen is prone to scaling phenomenon, resulting in low filtering effect. Therefore, the present invention proposes a kind of anti-scaling suction for ships that is provided ...

Problems solved by technology

The common problem is that impurities are easy to accumulate in the filter and it is difficult to clean, and the existing suction coarse water filter has poor filtering effect during use, and the filter element or filter screen is prone to fouling, resulting in low filtering effect. Therefore, the present invention proposes an anti-scaling suction for ships with multiple filter layers, and drives the brush plate to rotate to clean the inner wall of the filter layer while the water is flowing, and scrapes and accumulates the cleaned dirt to a designated position. coarse water filter
