AI Technical Summary
[0023] This utility model provides a floor drain device for ships, which has the following advantages: The vortex mechanism of the floor drain device is distributed inside the filter basket, and the magnetic debris collector is connected to the bottom middle of the filter basket. When sewage is discharged from the ship through the drain pipe, mucus, hair, iron filings, and sand will be concentrated to the center of the vortex under the action of the vortex mechanism, and then fall into the magnetic debris collector. The magnetic debris collector can directly attract metal particles in the impurities, causing mucus, hair, and sand to clump together and settle, so as to concentrate in the magnetic debris collector. At this time, the water will be discharged through the filter holes around the filter basket, making it less likely to form water accumulation on the ship. The filter basket can be removed every once in a while to clean the clumps of sedimented impurities. At the same time, an anti-siphon mechanism is set at the core cylinder to reduce the backflow rate, thereby avoiding pitting corrosion on the ship, reducing ship maintenance costs, and improving the service life of the ship.

[0033] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0034] like Figure 1 As shown, this utility model provides a floor drain device for ships, which is installed at the location of the ship's drainage pipe. The floor drain device includes:
[0035] Core tube 1;
[0036] Filter basket 2, the top port of filter basket 2 is detachably connected to core cylinder 1;
[0037] A swirling mechanism is located inside the filter basket 1.
[0038] The magnetic debris collector 3 is connected to the bottom center of the filter basket 2.
[0039] Anti-siphon mechanism, which is connected to core cylinder 1.
[0040] Specifically, to address the current problems of ship drainage pipe filters being easily clogged by impurities and seawater backflow causing siphoning, leading to water accumulation and pitting corrosion, this invention provides a ship floor drain device. The components of this drain device can be injection molded from glass fiber reinforced polypropylene (GFPP) to improve corrosion resistance. The filter basket 2 of the drain device is inverted trapezoidal, and the swirling mechanism is distributed inside the filter basket 2. The magnetic debris collector 3 is connected to the bottom center of the filter basket 2. When sewage is discharged from the ship through the drainage pipe, mucus, hair, iron filings, and gravel are collected in the swirling flow. Under the action of the mechanism, the debris will be concentrated at the center of the vortex and then fall into the magnetic debris collector 3. The magnetic debris collector 3 can directly attract metal particles in the debris, causing mucus, hair, and sand to clump together and settle, thus concentrating them in the magnetic debris collector 3. At this time, the accumulated water will be discharged through the filter holes around the filter basket 2, making it less likely for water to accumulate on the ship. The filter basket 2 can be removed every once in a while to clean the clumps of sedimented debris. At the same time, an anti-siphon mechanism is set at the core cylinder 1 to reduce the backflow rate, thereby avoiding pitting corrosion on the ship, reducing ship maintenance costs, and increasing the service life of the ship.
[0041] like Figure 3 As shown, preferably, the swirling mechanism includes multiple spiral guide vanes 4, which are distributed on the inner side of the filter basket 2, and each spiral guide vane 4 is inclined.
[0042] Specifically, the spiral guide vane 4 is set at an angle, and the angle between the spiral guide vane 4 and the axis of the filter basket 2 is 60°. The spiral guide vane 4 can form a spiral vortex. Through the spiral guidance of multiple spiral guide vanes 4, mucus, hair, iron filings, and gravel can be concentrated to the center of the vortex and then fall into the magnetic debris collection position.
[0043] Preferably, the magnetic debris collector 3 is a strong magnetic neodymium iron boron debris collector, and the magnetic debris collector 3 is circular.
[0044] Specifically, the strong magnetic NdFeB debris collector has a very strong magnetic field strength. Any hair or fiber containing ferromagnetic particles will be attracted here. Mucus, hair, and sand particles will swirl around the strong magnetic NdFeB debris collector and eventually clump together and settle.
[0045] Preferably, the anti-siphon mechanism includes a floating ball valve and a duckbill check valve, which are respectively disposed inside the core cylinder 1 and at the bottom port of the core cylinder 1.
[0046] Specifically, the combination of floating ball valves and duckbill check valves reduces the backflow rate and can prevent pitting corrosion on ships.
[0047] like Figure 2 As shown, preferably, the floating ball valve includes:
[0048] At least four locking protrusions 6, the diameter of the middle part of the core cylinder 1 is smaller than the diameter of the rest of the core cylinder 1, at least four locking protrusions 6 are located below the middle part of the core cylinder 1, and at least four locking protrusions 6 are distributed on the inner side of the core cylinder 1.
[0049] The floating ball 7 is supported on the ends of at least four protrusions 6, and the diameter of the floating ball 7 is larger than the diameter of the middle part of the core cylinder 1.
[0050] The diameter of the floating ball 7 is equal to eighty percent of the diameter of the other part of the core cylinder 1.
[0051] Specifically, the density of floating ball 7 is 0.95 g / cm³. 3 When sewage from the ship is discharged through the sewer pipe, the sewage can flow out through the gap between the floating ball 7 and the inner side of the core cylinder 1. When backflow occurs, since the diameter of the floating ball 7 is larger than the diameter of the middle part of the core cylinder 1, the middle part of the core cylinder 1 will be able to prevent the floating ball 7 from floating up. At this time, the floating ball 7 will be sealed inside the core cylinder 1 to prevent seawater backflow and siphoning.
[0052] Preferably, the duckbill check valve includes:
[0053] Valve plate 8 is hinged to the bottom port of core cylinder 1, and valve plate 8 can cover the bottom port of core cylinder 1.
[0054] Tension spring 9, one end of which is connected to valve plate 8, and the other end of which is connected to the inside of core cylinder 1.
[0055] Specifically, valve plate 8 is a silicone valve plate, and the opening pressure of valve plate 8 is set to 0.02MPa. When sewage from the ship is discharged through the sewer pipe, the sewage can push open valve plate 8 and flow out. When backflow occurs, under the force of the water flow and the action of tension spring 9, valve plate 8 will seal the inside of core cylinder 1 to prevent seawater backflow and siphon phenomenon.
[0056] like Figure 4 As shown, preferably, the drain device for ships includes a filter plate 10, which has multiple honeycomb holes 11. The filter plate 9 is located below the filter basket 2, and the filter plate 10 is connected to the inner side of the core cylinder 1.
[0057] Specifically, the filter plate 10 is in the shape of an inverted trapezoid. The filter plate 10 is used to further filter mucus, hair, iron filings, and gravel. Under the action of the eddy current transmitted from above, the debris can also be clumped and settled on the filter plate 10 and concentrated at the magnetic debris collector 3 above.
[0058] like Figure 5 As shown, preferably, the drain device for ships also includes a panel 12, which is attached to the top port of the filter basket 2, and has a plurality of elongated holes 13 distributed on the panel 12.
[0059] Specifically, panel 12 is used to filter larger impurities to prevent filter basket 2 from becoming clogged.
[0060] Preferably, the drain device for ships also includes a seat plate 5, which has an installation hole. The top of the filter basket 2 is connected to the inside of the installation hole, and the seat plate 5 is used to fit against the top of the core tube 1.
[0061] Specifically, the seat plate is placed on top of the core tube 1, and can be lifted at any time to clean the impurities in the filter basket 2.
[0062] In summary, when the ship drain device of this application is implemented, during the sewage discharge process, mucus, hair, iron filings, and gravel will be concentrated to the center of the vortex under the action of the spiral guide plate 4, and then fall into the magnetic debris collector 3. The magnetic debris collector 3 can directly attract metal particles in the impurities, causing mucus, hair, and sand to clump together and settle, thus concentrating in the magnetic debris collector 3. At this time, the accumulated water will be discharged through the filter holes around the filter basket 2, making it less likely for water to accumulate on the ship. The filter basket 2 can be removed every once in a while to clean the clumps of settled impurities. At the same time, a floating ball valve and a duckbill check valve are installed at the core cylinder 1. With the combined action of the two anti-backflow valves, the backflow rate is reduced, thereby avoiding pitting corrosion on the ship, reducing ship maintenance costs, and improving the service life of the ship.
[0063] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
