[0001] The invention relates to the technical field of ship high-pressure air systems, in particular to a ship high-pressure air system filter. Background Art

[0002] At present, in the construction of ships, the compressed air system needs to filter the compressed air through a filter when in use. The filter screen in the existing compressed air filter is easily broken and broken by large particles after reaching the accuracy standard, affecting the operation of the entire system, and even destroying the starting air system of the equipment, affecting the service life of the filter structure, and with the continuous filtering of the compressed air, it is easy to cause too many impurities to block the filter structure, affecting the filtering effect of the filter structure, and the practicality is poor. Therefore, this application provides a ship high-pressure air system filter to meet the needs. Summary of the invention

[0003] The main purpose of the present invention is to provide a ship high-pressure air system filter, which can effectively solve the problems in the background technology.

[0005] Preferably, the auxiliary filter unit comprises a filter screen arranged inside the filter installation tube, and the filter screen is adapted to the inner diameter of the filter installation tube, a section of the filter installation tube is fixedly connected with a sealing flange, a rotating shaft is rotatably connected to the sealing flange, and the rotating shaft is plugged into the inside of the filter screen, a rotating blade is fixedly connected to the rotating shaft, and the rotating blade is plugged into the inside of the filter body, a spiral blade is arranged on one side of the rotating blade, the spiral blade is plugged into the inside of the filter screen, and the spiral blade is adapted to the filter screen;

[0006] Preferably, the rotating unit includes a driving gear fixedly connected to one end of the rotating shaft, a plurality of driven gears are rotatably connected to the sealing flange, and the driving gear is meshingly connected to the driven gears, an internal gear ring is fixedly connected to the filter screen, and a plurality of the driven gears are meshingly connected to the internal gear ring.

[0007] Preferably, the sealing flange is connected to the end of the filter mounting tube by bolts.

[0008] Preferably, the number of the driven gears is three.

[0009] Preferably, the rotating blade is an arc-shaped structure with one side bent.

[0010] Preferably, the filter screen is a cylindrical filter structure.

[0011] Preferably, both ends of the filter body are fixedly connected with flanges, and both flanges are provided with mounting holes.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. During the use of the ship's high-pressure air system filter, as the air flows, the air is filtered through the filter structure. As the air flows, the auxiliary filter unit is driven to rotate, and the filter structure is cleaned by the auxiliary filter unit to reduce blockage of the filter structure. The impurities trapped by the filter can be guided to the bottom end of the filter installation tube, which is convenient for later processing and improves practicality. As the auxiliary filter unit rotates, the rotating unit is driven to rotate, and the filter structure is driven to rotate in the opposite direction through the rotating unit, thereby using different parts of the filter structure to filter the air, thereby improving the service life of the filter structure and improving practicality.

[0014] 2. By setting rotating blades and spiral blades, when air passes through the filter, the air first enters the filter body, is guided by the rotating blades, and then is filtered through the filter. As the air flows in, the rotating blades are driven to rotate, and the spiral blades are driven to rotate with the cooperation of the rotating shaft. The inner wall of the filter is cleaned by the spiral blades to reduce residual impurities and improve the filtering effect of the filter. The rotation of the spiral blades pushes the impurities in the filter toward the filter mounting tube to collect the impurities and facilitate subsequent processing. The use of the auxiliary filter unit improves the filtering effect of the filter, and the filter is inclined to increase the filtering area of ​​the air and reduce the impact of the air flow on the filter, thereby increasing the service life of the filter and improving practicality.

[0015] 3. By setting a driving gear and an inner gear ring, as the rotating shaft rotates, the driving gear is driven to rotate, and the driving gear drives multiple driven gears to rotate in the opposite direction, and the driven gear drives the inner gear ring to rotate, and then the inner gear ring drives the filter to rotate, so that the filter rotates in the opposite direction relative to the spiral blade. The reverse rotation of the filter improves the cleaning effect of the spiral blade on the inner wall of the filter, which is convenient to use. At the same time, the rotation of the filter can prevent the air from continuously impacting one part of the filter when passing through the filter, thereby increasing the service life of the filter and having good practicality.

During the use of the ship high-pressure air system filter, as the airflow flows, the air is filtered through the filter structure, and as the airflow flows, the auxiliary filter unit 2 is driven to rotate, and the filter structure is cleaned by the auxiliary filter unit 2, thereby reducing the blockage of the filter structure, and the impurities trapped by the filtration can be guided to the bottom end of the filter mounting pipe 4, which is convenient for later processing and improves practicality. As the auxiliary filter unit 2 rotates, the rotating unit 3 is driven to rotate, and the filter structure is driven to rotate in the opposite direction through the rotating unit 3, thereby realizing the use of different parts of the filter structure to filter the air, improving the service life of the filter structure, and improving practicality.

[0025] like Figure 1 and Figure 4 As shown, the auxiliary filter unit 2 includes a filter screen 5 arranged inside the filter mounting tube 4, and the filter screen 5 is adapted to the inner diameter of the filter mounting tube 4, the filter screen 5 is a cylindrical filter structure, a section of the filter mounting tube 4 is fixedly connected with a sealing flange 6, the sealing flange 6 is connected to the end of the filter mounting tube 4 by bolts, a rotating shaft 7 is rotatably connected to the sealing flange 6, and the rotating shaft 7 is inserted into the inside of the filter screen 5, a rotating blade 8 is fixedly connected to the rotating shaft 7, and the rotating blade 8 is inserted into the inside of the filter body 1, the rotating blade 8 is an arc-shaped structure with one side bent, a spiral blade 9 is arranged on one side of the rotating blade 8, the spiral blade 9 is inserted into the inside of the filter screen 5, and the spiral blade 9 is adapted to the filter screen 5.
