Description

Technical Field

[0001] The utility model generally relates to the technical field of shipping, and more particularly to a filter and a ship. Background Art

[0002] The global shipping industry is actively promoting the use of green alternative fuels. Compared to traditional fuels, methanol fuel can significantly reduce greenhouse gas emissions by up to 95% in Life Cycle Assessments (LCA). Furthermore, as a room-temperature liquid fuel, methanol offers significantly higher safety compared to other options such as liquefied natural gas (LNG), ammonia, and hydrogen. Therefore, it has become one of the key new green fuels for the future development of the shipping industry. When refueling new methanol-fueled vessels, a conical filter is required at the filling station manifold to temporarily filter and flush out liquid or gas entrained equipment and residual solid particles in the pipes. This ensures the proper functioning of fluid handling equipment such as pumps and heat exchangers, as well as instrumentation, ensuring a stable process and safe production. Currently, conical filters are often connected to pipelines using a compression seal, which is prone to leakage. If the conical filter becomes clogged, it is difficult to clean or replace the filter in a timely and safe manner.

[0003] Therefore, it is necessary to provide a filter and a vessel to at least partially solve the above problems. Utility Model Content

[0060] The utility model provides a filter.

[0061] See also Figure 1 The filter 110 includes a filter body 120 and a filter screen 130. Specifically, the filter body 120 has a raised surface and a first mounting hole 120c. The number of the first mounting holes 120c is at least two, and the first mounting holes 120c pass through the filter body 120 along the axial direction of the filter 110. The filter screen 130 is constructed in a conical shape, and the filter screen 130 has a tip 130a and a bottom end 130b. The bottom end 130b is connected to the filter body 120, and along the axial direction of the filter 110, the bottom end 130b is closer to the filter body 120 than the tip 130a. It should be noted that the raised surface is arranged around the outside of the filter screen 130, and along the axial direction of the filter 110, the raised surface protrudes from the outer edge of the first mounting hole 120c.

[0062] According to the filter 110 of the present invention, by setting the first mounting hole 120c to cooperate with the raised surface, when the filter 110 is connected to other components, the installation accuracy of the filter 110 and the sealing performance of the connection between the filter 110 and other components can be improved, thereby ensuring the working effect of the filter 110.

[0063] See also Figure 1 and Figure 2 The raised surface includes a first raised surface 120a and a second raised surface 120b. The first raised surface 120a and the second raised surface 120b are spaced apart along the axis of the filter 110. Along the axis of the filter 110, the first raised surface 120a is closer to the tip 130a than the second raised surface 120b. It will be understood that the filter body 120 has a central hole that communicates with the filter screen 130. Preferably, the filter screen 130 partially extends into the interior of the filter body 120. For example, the edge of the bottom end 130b of the filter screen 130 is welded to the inner circumferential surface of the filter body 120. Figure 1 and Figure 2 In the embodiment of the present invention, the raised surface extends radially along the filter 110 to the outer edge of the aforementioned central hole; in other words, the raised surface is located outside the filter screen 130, and radially along the filter 110, the outer edge of the bottom end 130b of the filter screen 130, the inner edge of the raised surface, and the inner edge of the aforementioned central hole can be configured to be flush, with the three being spaced apart along the axis of the filter 110. Furthermore, the filter screen 130 includes a sieve plate 131 and a screen mesh 132. The sieve plate 131 has a plurality of mesh holes 131a, and the screen mesh 132 is adapted to and connected to the sieve plate 131. Preferably, the mesh holes 132a of the screen mesh 132 correspond one-to-one with the mesh holes 131a, and the screen mesh 132 is located inside the sieve plate 131.

[0064] See also Figure 3 and Figure 4 The cross section of the filter body 120 is annular, and at least two first mounting holes 120c are evenly distributed around the axis of the filter 110. Figure 3 and Figure 4 In the embodiment, there are eight first mounting holes 120c, distributed in a circular array around the axis of the filter 110. Furthermore, the first mounting holes 120c are located on the periphery of the first raised surface 120a and the second raised surface 120b. In other words, along the radial direction of the filter 110, the outer edges of the first raised surface 120a and / or the second raised surface 120b are closer to the center of the filter body 120 than the outer edges of the first mounting holes 120c.

[0065] The present invention also provides a ship. Figure 5 and Figure 6The vessel includes a pipeline 140 and the aforementioned filter 110. The pipeline 140 is detachably connected to the filter 110. It is understood that the pipeline 140 is used to transport fuel such as methanol. Preferably, when the pipeline 140 is connected to the filter 110, the fuel is moved in the direction of flow (see FIG. Figure 5 as well as Figure 6 ), the tip 130a is located in front of the bottom end 130b. In an embodiment not shown, along the flow direction of the fuel, the bottom end 130b may be located in front of the tip 130a.

[0066] Furthermore, the vessel also includes fixing members 150, which are arranged in pairs, with adjacent fixing members 150 spaced apart along the axis of the filter 110. When the pipeline 140 is connected to the filter 110, the filter body 120 is located between the fixing members 150 adjacent to each other along the axis of the filter 110. In an embodiment not shown, a single filter 110 may be connected to only one fixing member 150, which is connected to the filter body 120. It will be understood that the first mounting hole 120c is used to connect to the fixing member 150, and the fixing member 150 has a second mounting hole 150a. When the pipeline 140 is connected to the filter 110, the second mounting hole 150a corresponds to the first mounting hole 120c along the axis of the filter 110. The fixing member 150 is configured, for example, as a flange adapted to fit the filter 110. The vessel further includes a fastener 160 connected to the first mounting hole 120c and the second mounting hole 150a corresponding to the position along the axis direction of the filter 110, so that the filter 110 is connected to the fixing member 150. The fastener 160 can be constructed as a combination of a stud 161 (or bolt) and a nut 162. For example Figure 5 and Figure 6 In the embodiment, the stud 161 is arranged along the axial direction of the filter 110 , and a single stud 161 is connected to two nuts 162 . The fixing member 150 and the filter body 120 are sandwiched between the adjacent nuts 162 along the axial direction of the filter 110 .

[0067] In order to improve the sealing performance of the connection between the filter 110 and the pipeline 140, the ship further includes a gasket 163, which is located between the fixing member 150 and the filter body 120 adjacent to each other along the axis of the filter 110. Figure 5 and Figure 6In the embodiment, gaskets 163 are arranged in pairs, with adjacent gaskets 163 spaced apart along the axis of filter 110. When pipe 140 is connected to filter 110, gaskets 163 are located between adjacent fixing members 150 and filter body 120 along the axis of filter 110. Furthermore, gaskets 163 do not protrude outward from filter body 120 in the radial direction of filter 110. Gaskets 163 have third mounting holes 163a. ​​When pipe 140 is connected to filter 110, third mounting holes 163a correspond to first mounting holes 120c along the axis of filter 110.

[0068] According to the filter of the present invention, when liquid fuel enters the filter, its solid impurities are blocked, while the clean filtrate can pass through the filter screen and enter the next process. When the filter needs to be cleaned, it can be easily disassembled and cleaned relative to the pipeline, making it easy to maintain. Furthermore, the interaction between the sealing surface, mounting holes, and gasket ensures a tight seal between the pipeline and the filter, preventing leakage during use and disassembly, and improving the safety of other components within the ship.
