Anti-corrosion coarse water filter based on ship equipment

Abstract

The invention discloses an anti-corrosion coarse water filter based on ship equipment, and belongs to the field of coarse water filters. The anti-corrosion coarse water filter comprises a mounting barrel, a water inlet pipe fixedly communicates with the right side wall of the mounting barrel, a water drainage pipe fixedly communicates with the left side wall of the mounting barrel, and a filter screen is fixedly connected in the mounting barrel. By arranging a heating mechanism and a self-locking mechanism, after drainage work is finished, the self-locking mechanism is automatically opened, under the action of a first reset spring, a threaded plate moves downwards, a threaded rod rotates reversely, a water inlet pipe is sealed again through a sealing block, a first through hole and a second through hole are communicated again, heated seawater washes a filter screen, and the water inlet pipe is sealed again. When the seawater is in a heating state, the sea salt adhered to the filter screen can be dissolved, so that the sea salt is separated from the surface of the filter screen, the sea salt is prevented from blocking the filter screen, meanwhile, the sea salt is prevented from corroding the filter screen, the filtering effect of the filter screen is improved, and the service life of the filter screen is prolonged.

Description

technical field [0001] The invention discloses an anti-corrosion rough water filter based on ship equipment in the field of coarse water filters. Background technique [0002] The coarse water filter is used to be installed in the fuel room of the ship, and the inhaled sewage flows into the coarse water filter, and is filtered through the filter mechanism inside the main body to remove impurities in the sewage, so that it can filter out clean water, which is convenient use. [0003] In the prior art, the coarse water filter is used as an important machine for ships. When the ship is driving in seawater, due to the presence of a large amount of sea salt in the seawater, when the coarse water filter filters seawater for a long time, the sea salt in the seawater will accumulate on both sides of the filter plate , not only cause blockage, but also the corrosiveness of sea salt will corrode the filter plate, thereby reducing the filtering function of the filter plate, resulting ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of anti-corrosion type coarse water filter based on ship equipment, to solve the above-mentioned background technology. There is a large amount of sea salt in seawater. When the coarse water filter filters seawater for a long time, the sea salt in the seawater will accumulate on both sides of the filter plate, which will not only cause blockage, but also the corrosion of sea salt will corrode the filter plate, thereby reducing the filtration capacity of the filter plate. function, resulting in insufficient filtration of the coarse water filter
