Description

Technical Field

[0001] This utility model relates to the field of marine engineering technology, and more specifically, it relates to a filtration assembly for ships. Background Technology

[0002] During ship operation, filtration of various liquids is a crucial aspect of the stable operation of ship systems. These liquids include fuel oil, fresh water, and seawater, all of which require filtration components to remove impurities and protect the ship's engines, cooling systems, and other vital equipment from damage.

[0003] For example, the patent announcement number CN219506216U discloses a filtration device for ship water circulation, which includes a sewage pipe, an outlet pipe, and a filter component. The filter component is movably connected to the sewage pipe and the outlet pipe, and includes a filter screen and a housing. When cleaning the filter screen, force is applied to the annular component to rotate it, causing the threaded ring and the internal thread to rotate and separate, so that the sewage pipe and the housing are separable. Force is applied to the pressing component and the tank body to separate the pressing component from the tank body. Then, force is applied to the fastener to pull it out of the groove, so that the fastener and the plate component are separable, so that the filter screen can be replaced and the filtered debris can be effectively cleaned.

[0004] In the above-mentioned case, the filter screen is installed and removed using only a single clip. During the ship's voyage, a huge water flow impact force is generated. This impact force can cause the clip to loosen, making the filter screen prone to falling off due to the loose clip. This results in the inability to filter water and also affects the normal operation of the ship. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a filter component for ships that improves the stability of the filter screen.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A filtration assembly for a ship includes a sewage pipe and a filter element. The filter element is positioned below and detachably connected to the sewage pipe.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] like Figures 1 to 3 As shown, the filtration assembly for a ship includes a sewage pipe 1 and a filter element 2. The filter element 2 is located below the sewage pipe 1. The filter element 2 includes a filter screen 3 and mounting plates 4 located on both sides of the filter screen 3. Both mounting plates 4 are connected to the filter screen 3.

[0027] A surrounding plate 10 is provided on the mounting plate 4, and the surrounding plate 10 is positioned above the mounting plate 4 and perpendicular to the mounting plate 4. A rotating shaft is mounted on the mounting plate 4, and one side of the surrounding plate 10 is on the rotating shaft. When the surrounding plate 10 rotates, the surrounding plate 10 can rotate around the rotating shaft.

[0028] Both sides of the sewage pipe 1 are equipped with support plates 5. The support plates 5 have grooves 6 and holes 7. Springs 8 and fixing blocks 9 are installed in the grooves 6. There are two springs 8. The fixing blocks 9 are placed between the two springs 8. One end of the spring 8 and one side of the fixing plate are connected to the inner wall of the groove 6. The fixing blocks 9 have connection holes 18.

[0029] A positioning plate 11 is installed on the enclosure 10. Two pressing blocks 19 are installed on the positioning plate 11. The two pressing blocks 19 extend into the groove 6 and abut against the two springs 8 respectively. When the two pressing blocks 19 abut against the two springs 8 respectively, the positioning plate 11 also engages and is fixed with the connecting hole 18.

[0030] A locking tube 12 is also installed on the enclosure plate 10. A movable through hole 13 is provided on the enclosure plate 10. Internal threads are installed on the inner wall of the movable through hole 13 and the inner wall of the hole position 7. External threads are installed on the outer wall of the locking tube 12. When the locking tube 12 is rotated, it passes through the movable through hole 13 into the hole position 7. The internal threads and external threads rotate to fix the locking tube 12 in the movable through hole 13 and the hole position 7.

[0031] When the locking tube 12 is removed from the movable through hole 13 and the hole 7, the locking tube 12 is rotated, and the internal thread and the external thread rotate. The locking tube 12 first rotates out of the hole 7 and finally rotates out of the movable through hole 13. The locking tube 12 can fix the enclosure plate 10 and the support plate 5, thereby fixing the filter element 2 and the sewage pipe 1.

[0032] A rotating rod 14 is installed on the locking tube 12. One end of the rotating rod 14 is fixedly connected to the locking tube 12. Five blind holes 15 are opened on the rotating rod 14. An annular hole 16 is opened on the surrounding plate 10. The movable through hole 13 is placed in the annular hole 16. Five protrusions 17 are provided on the annular hole 16, which are distributed around the center of the annular hole 16 as a reference plane. When the locking tube 12 is fixed in the movable through hole 13 and the hole 7, the protrusions 17 are also engaged and fixed with the groove, which increases the stability between the surrounding plate 10 and the support plate 5, and further increases the stability between the filter element 2 and the sewage pipe 1.

[0033] Working principle: The two pressing blocks 19 on the positioning plate 11 press the corresponding springs 8 respectively. During the pressing process, the positioning plate 11 engages and is fixed with the connecting hole 18, thereby fixing the sewage pipe 1 and the filter element 2. The first fixing of the filter screen 3 is achieved through the snap-fit.

[0034] Rotate the rotating rod 14 so that it first passes through the movable through hole 13 and then is placed in the hole 7. The external thread and internal thread are screwed together to fix the ring plate 10 and the support plate 5, thereby achieving the second fixation of the filter screen 3.

[0035] When the rotating rod 14 is fixed in the movable through hole 13 and the hole 7, the protrusion 17 in the annular hole 16 engages with the blind hole 15 on the rotating rod 14, thus fixing the rotating rod 14 to the enclosure plate 10 and achieving the third fixing of the filter screen 3. Through these three fixings, the stability of the filter screen 3 is improved, preventing loosening caused by water flow impact, ensuring the stable operation of the ship, and reducing the safety risks caused by the filter screen 3 falling off.

[0036] When disassembling the filter screen 3, first rotate the rotating rod 14, and the protrusion 17 in the annular hole 16 will be dislodged from the blind hole 15 on the rotating rod 14. Then the rotating rod 14 will rotate out of the hole 7 and the movable through hole 13 in sequence. Finally, the surrounding plate 10 will be pried outward, and the surrounding plate 10 will rotate around the mounting plate 4, so that the filter element 2 can be removed from the sewage pipe 1.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
