Blocking-prevention seawater filter

Abstract

The invention discloses a blocking-prevention seawater filter, which comprises a barrel (1) with a water inlet (2) and a water outlet (4); a filter drum (3) is arranged in the barrel (1); the upper end of the barrel (1) is provided with a cover plate (9); the cover plate (9) is provided with a high-pressure water inlet (6) and a compressed air inlet (8); and the bottom parts of the high-pressure water inlet (6) and the compressed air inlet (8) extend into the barrel (1) and are connected into a whole through an annular injection pipe (5). According to the blocking-prevention seawater filter disclosed by the invention, the filter drum in the filter is washed by utilizing compressed air and high-pressure water, so that blockages fall off from a filter screen and are discharged out of the filter through a drain outlet to achieve the goal of preventing blocking.

Description

technical field [0001] The invention relates to an anti-clogging seawater filter. Background technique [0002] Natural phenomena such as tides and storms can easily cause seawater to be turbid, especially in the Bohai Sea area, where the Yellow River carries a large amount of sediment when it enters the sea. Ships sailing here or oil platforms operating nearby are extremely vulnerable to seawater in the process of pumping seawater. It is easy to cause the blockage of the seawater system; in addition, seawater is rich in shellfish and algae, which are easy to accumulate and grow on the inner wall of the seawater pipeline, which also gradually blocks the seawater system. Once the seawater system is blocked, the water equipment cannot work normally, and even If the equipment is damaged, the most serious consequence is that in the event of a fire, the supply of fire-fighting water cannot be guaranteed, and the shipwreck and death are imminent. Therefore, a filter is needed, in...
