Fine filtration type seawater filter structure

Abstract

The invention discloses a fine filtration type seawater filter structure. A butterfly check valve is arranged in a seawater outlet, a sealing cover is arranged at the bottom of a box body, a through hole is formed in the sealing cover, the bottom of the through hole is connected with a seawater inlet pipe, a cylindrical filter screen is arranged at the top of the through hole, a top plate is arranged at the top of the cylindrical filter screen, and two glands are arranged at the top of the top plate. One gland is connected with the top plate through a fixing mechanism, an anti-corrosion zinc block is arranged at the bottom of the box body, a base is arranged at the bottom of the anti-corrosion zinc block, the base and the inner wall of the box body are fixed through a quick insertion mechanism, and a vertical polar polymer resin adsorption layer, a non-polar polymer resin adsorption layer and a porous medium filter plate are sequentially arranged close to the inside of the box body. A stirring shaft is arranged at the end, close to the seawater outlet, of the box body, the bottom of the stirring shaft is connected with a driving motor, and a feeding mechanism is arranged on the other gland. According to the invention, shaking of the filter screen can be reduced while the filter screen is convenient to disassemble and assemble, the anti-corrosion zinc block can be quickly disassembled and assembled, the oxygen content in the box body is reduced, the structure is simple, and use is convenient.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a fine filter type seawater filter structure. Background technique [0002] With the continuous development of society and the rapid innovation of science and technology, the field of mechanical technology is also widely used in many manufacturing fields; and in the field of shipbuilding, when manufacturing high-speed diesel engines for high-speed boats, seawater will enter the diesel engines and Seawater is doped with many impurities (such as sediment, algae floating matter, etc.), when these impurities enter the diesel engine, they will damage the impeller of the water pump or block the cooler core, and even corrode the cylinder block, pump body and impeller of the engine. Thus affecting the service life of the engine; in order to solve the above problems in the existing technology, people often install filters at the water inlet of the engine to filter the seawater.

Problems solved by technology

[0002] With the continuous development of society and the rapid innovation of science and technology, the field of mechanical technology is also widely used in many manufacturing fields; and in the field of shipbuilding, when manufacturing high-speed diesel engines for high-speed boats, seawater will enter the diesel engines and Seawater is doped with many impurities (such as sediment, algae floating matter, etc.), when these impurities enter the diesel engine, they will damage the impeller of the water pump or block the cooler core, and even corrode the cylinder block, pump body and impeller of the engine. Thus affecting the service life of the engine; in order to solve the above problems in the existing technology, people often install filters at the water inlet of the engine to filter the seawater. However, the seawater will always impact the filter screen during work, which may cause the filter screen to fall off, thereby affecting normal use. In addition, since the anti-corrosion zinc block is a consumable, it needs to be replaced frequently. The existing anti-corrosion zinc Blocks are not easy to disassemble, thereby increasing the man-hours for replacement and maintenance. Moreover, after the existing seawater fine filtration device is used for a long time, due to the microorganisms in the seawater, the water quality will be corrupted and deteriorated, which will seriously affect the quality of the seawater. The final filtration effect. In addition, the quality of seawater in some areas is poor, and it is difficult to achieve effective purification only by the filter. Therefore, an additional filter reagent addition device is required, which will increase the cost of filtration.
