The invention relates to a multi-stage flow-cleaning device for a water inlet of a ship water circulation system. The multi-stage flow-cleaning device for the water inlet of the ship water circulationsystem structurally includes a cabin, a hull and a propulsion. the lower surface of the cabin is embedded in the upper surface of the hull, the propulsion is installed in the lower left corner of thehull, when the ship proceeds, by using the impact force of the water flow on a drainage ring during advancing, the drainage ring rotates to suck the water flow to a flow cleaner, an annular pipe inside the flow cleaner is used to divert the water flow, to make the water flow to produce centrifugal inertial force, and impact on a flow-cleaning plate to separate the sediment under the interceptionof the multi-stage flow-cleaning plate, thereby reducing the sediment concentration of the water flow, preventing the sediment from entering a water circulation pipeline to affect the heat exchange effect of the water flow, thereby accelerating the reduction of the temperature of an engine, keeping the engine at an appropriate temperature for operation and effectively prolonging the service life.
Description
technical field [0001] The invention relates to a multi-stage clearing device for a water inlet of a water circulation system of a ship, and relates to the field of ships. Background technique [0002] In the ship water circulation system, there is usually a water circulation inlet at the bottom of the ship to suck the water in the water area into the engine to circulate and cool down, so as to ensure the normal operation of the engine. [0003] However, because the water inlet needs to be close to the engine, it is installed at the stern. When the ship passes through the shallows, the stern propeller will roll up the sand and be sucked by the water inlet, so that the sand will accumulate in the water circulation pipe. Due to the low specific heat capacity of the sand, the heat dissipation effect will be reduced. Poor, the sediment attached to the inner wall of the pipe will cause the heat transfer efficiency of the water circulation system to decrease, which will cause the ...
