Technical Field
[0001] The utility model relates to the technical field of ships, in particular to a marine sewage well and a ship. Background Art
[0002] A sewage well is a small container for temporarily placing ship sewage, and is used for treating oily sewage, impurity-containing sewage, etc. generated in areas such as engine rooms and cargo holds. Specifically, the sewage well can perform preliminary gravity separation of oil, water, and impurities in the sewage, and then convey the sewage to a sewage treatment device for further treatment through equipment such as sewage pumps, and is a component of the ship bilge water system.
[0003] Existing marine sewage wells are usually a well trap, and a sewage well cover covers the entire sewage well area, and only treats sewage through physical sedimentation, and the treatment effect on sewage is not good. Moreover, when overhauling, it is necessary to completely open a relatively large manhole cover, which is very inconvenient. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a marine sewage well and a ship, so as to solve the technical problems in the prior art that the treatment effect on sewage is not good and it is very inconvenient to completely open a relatively large manhole cover during overhaul, and to achieve the technical effects of improving the sewage treatment effect and facilitating overhaul.
[0005] As conceived above, the technical solution adopted by the utility model is as follows:
[0006] A marine sewage well, comprising:
[0007] A well body, in which a receiving cavity is arranged, and the upper end of the receiving cavity has an opening;
[0008] At least one partition plate, which is arranged in the receiving cavity to at least divide the receiving cavity into a first chamber and a second chamber. A first through hole is formed in the partition plate, and a first filtering structure is arranged in the first through hole. The lowest point of the first through hole is higher than the bottom plate of the receiving cavity, and the first chamber and the second chamber are communicated through the first filtering structure;
[0009] A first cover plate, which is detachably arranged at the opening of the first chamber;
[0010] A second cover plate, which is detachably arranged at the opening of the second chamber.
[0011] Further, the first filtering structure is a filter screen.
[0012] Further, a second through hole is formed in the first cover plate, so that sewage enters the first chamber from the first cover plate through the second through hole.
[0013] Further, the number of the second through holes is multiple so that a second filtering structure is formed on the first cover plate.
[0014] Further, a plurality of first through holes are provided in the partition plate.
[0015] Further, a water suction pump is further included, and the water suction end of the water suction pump is located in the second chamber.
[0016] Further, a third filtering structure is further included, and the third filtering structure is arranged at the water suction end of the water suction pump and can filter the sewage entering the water suction pump.
[0017] Further, a water suction pump mounting seat is arranged in the second chamber. The water suction pump mounting seat is a hollow structure with an opening. The water suction pump is arranged on the water suction pump mounting seat, and the water suction end of the water suction pump extends into the water suction pump mounting seat. The third filtering structure is arranged at the opening.
[0018] Further, handles are arranged on both the first cover plate and the second cover plate.
[0019] As described above, the technical solution adopted by the present utility model is as follows:
[0020] A ship includes the above-mentioned marine sewage well, and the sewage of the ship can enter the first chamber.
[0021] The beneficial effects of the present utility model: By providing at least one partition plate, the accommodating cavity of the well body is at least divided into a first chamber and a second chamber. A first filtering structure is arranged in the first through hole of the partition plate, and the lowest point of the first through hole is higher than the bottom plate of the accommodating cavity. The partition plate can block a part of the impurities deposited at the bottom of the first chamber, so that the sewage can precipitate in the first chamber; a first filtering structure is arranged at the first through hole. When the sewage that has undergone preliminary physical precipitation enters the second chamber from the first chamber, the first filtering structure filters the impurities floating in the water, which can improve the sewage treatment effect and greatly reduce the impurities in the sewage entering the second chamber; moreover, each chamber corresponds to a cover plate. Compared with the existing sewage well where the entire accommodating cavity shares a cover plate, when overhauling, only the cover plate of the corresponding chamber needs to be opened, which greatly reduces the inconvenience of overhauling.

For example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0034] As Figure 1 shown, a marine sewage well disclosed by the present utility model includes a well body, a partition plate 2, a first cover plate 31, and a second cover plate 32.
[0035] Among them, a receiving cavity 1 is provided in the well body, and the upper end of the receiving cavity 1 has an opening. At least one partition plate 2 is disposed in the receiving cavity 1 to at least partition the receiving cavity 1 into a first chamber 11 and a second chamber 12. A first through hole 21 is formed in the partition plate 2, and a first filtering structure 211 is disposed in the first through hole 21. The lowest point of the first through hole 21 is higher than the bottom plate of the receiving cavity 1, and the first chamber 11 and the second chamber 12 are communicated through the first filtering structure 211.
[0036] The first cover plate 31 is detachably disposed at the opening of the first chamber 11.
[0037] The second cover plate 32 is detachably disposed at the opening of the second chamber 12.
[0038] Specifically, as Figure 1 shown, in this embodiment, the partition plate 2 is one and is disposed in the receiving cavity 1 in the vertical direction. In other embodiments, the partition plate 2 can also be disposed obliquely.
[0039] Of course, in other embodiments, a plurality of partition plates 2 can be provided to partition the receiving cavity into more chambers, further improving the filtering effect.
[0040] It can be understood that by arranging a partition plate 2 in the accommodating cavity 1, the accommodating cavity 1 in the traditional sewage well is divided into two chambers by the partition plate 2, and the sewage passes through the first chamber 11 and the second chamber 12 in sequence. A first through hole 21 is arranged on the partition plate 2, and the sewage can enter the second chamber 12 from the first chamber 11 through the first through hole 21. A first filtering structure 211 is arranged in the first through hole 21 of the partition plate 2, and the lowest point of the first through hole 21 is higher than the bottom plate of the accommodating cavity 1, so that after the sewage enters the first chamber 11, it first gathers in the first chamber 11 and can precipitate in the first chamber 11. When the sewage in the first chamber 11 is higher than the lowest point of the first through hole 21 on the partition plate 2, it enters the second chamber 12 through the first through hole 21. The first filtering structure 211 arranged in the first through hole 21 can filter the sewage. By arranging the partition plate 2 to functionally partition the accommodating cavity 1 of the sewage well, the sewage entering the sewage well is precipitated in the first chamber 11 and then collected again in the second chamber 12, and a primary filtration is also carried out through the first filtering structure 211 during the process of re - collection, making the treatment of sewage more orderly and efficient. Moreover, the first chamber 11 and the second chamber 12 are respectively provided with cover plates. Compared with the existing sewage well where the entire accommodating cavity 1 shares a single cover plate, during maintenance, only the cover plate corresponding to the chamber needs to be opened for maintenance, greatly reducing the inconvenience during maintenance.
[0041] For example, when maintaining the first chamber 11, only the first cover plate 31 needs to be opened to maintain the inside of the first chamber 11; when maintaining the second chamber 12, only the second cover plate 32 needs to be opened to maintain the inside of the second chamber 12.
[0042] Furthermore, in this embodiment, the first filtering structure 211 is a filter screen. A filter screen is arranged in the first through hole 21. When the sewage in the first chamber 11 is higher than the lowest point of the first through hole 21 on the partition plate 2, it passes through the filter screen in the first through hole 21, undergoes a primary filtration, and then enters the second chamber 12.
[0043] Further optionally, the first filtering structure 211 is a multi - layer filter screen. Along the sewage flow direction, the mesh number of the filter screen gradually increases.
[0044] Further optionally, the first filtering structure 211 is detachably arranged at the first through hole 21 for cleaning or replacing the first filtering structure 211. Exemplarily, the first filtering structure 211 includes a surrounding frame and a filter screen fixed inside the surrounding frame, and the surrounding frame is detachably arranged on the partition plate 2 by screws.
[0045] Furthermore, a second through hole 311 is opened on the first cover plate 31 to enable the sewage to enter the first chamber 11 from the first cover plate 31 through the second through hole 311.
[0046] Specifically, as Figure 1As shown, in this embodiment, the well body is arranged on the lower surface of the cabin bottom. A second through hole 311 is formed on the first cover plate 31. When the sewage in the cabin bottom flows to the position of the first cover plate 31, it can pass through the second through hole 311 on the first cover plate 31 and enter the first chamber 11, and precipitate in the first chamber 11.
[0047] Of course, in other embodiments, the sewage can also directly enter the first chamber through other pipelines or the like.
[0048] Furthermore, the number of the second through holes 311 is multiple so as to form a second filtering structure on the first cover plate 31.
[0049] Specifically, as Figure 1 and Figure 3 shown, in this embodiment, a plurality of second through holes 311 are arranged on the first cover plate 31, and the plurality of second through holes 311 are arranged in an array. The plurality of second through holes 311 arranged in an array can form a second filtering structure. The size of the second through hole 311 is larger than the mesh size of the filter screen. When the sewage passes through the first cover plate 31 and enters the first chamber 11, the sewage can be preliminarily filtered by the second filtering structure, and larger impurities are filtered out to prevent larger impurities from entering the first chamber 11. This can not only reduce the filtering pressure of the first filtering structure 211 and extend the working cycle of the sewage well, but also enable the staff to handle larger impurities without opening the first cover plate 31 by only entering the cabin, which is convenient for the staff to recycle and handle larger impurities.
[0050] Furthermore, a plurality of first through holes 21 are arranged on the partition plate 2.
[0051] Specifically, in this embodiment (not shown), a plurality of first through holes 21 with sizes much larger than the mesh size of the filter screen are arranged on the partition plate 2, and filter screens are arranged in the plurality of first through holes 21. The plurality of filter screens form a first filtering structure 211. When the sewage enters the first chamber 11, it first precipitates in the first chamber 11, and then passes through the filter screens in the plurality of first through holes 21 and then enters the second chamber 12.
[0052] In other embodiments, the partition plate 2 can also adopt a structure similar to that of the first cover plate 31, and a plurality of first through holes 21 with sizes similar to the mesh size of the filter screen form a first filtering structure 211.
[0053] Furthermore, the marine sewage well further includes a water suction pump 4. The water suction end of the water suction pump 4 is located in the second chamber 12.
[0054] Specifically, as Figure 1As shown, in this embodiment, a water suction pump 4 is further disposed in the second chamber 12. After the sewage filtered by the second filtering structure and the first filtering structure 211 enters the second chamber 12, sedimentation continues in the second chamber 12. When the sewage in the second chamber 12 reaches a certain height, the sewage is discharged from the second chamber 12 through the water suction pump 4.
[0055] Further, the water suction end of the water suction pump 4 is located at the lower part of the second chamber 12.
[0056] Specifically, as Figure 1 shown, in this embodiment, the water suction end of the water suction pump 4 is disposed at the lower part of the second chamber 12. With this arrangement, even if the height of the sewage in the second chamber 12 is relatively low, the water suction pump 4 can still discharge the sewage.
[0057] To further improve the sewage treatment effect and prevent the water suction pump 4 from sucking away the impurities that have not settled in the second chamber 12, the marine sewage well further includes a third filtering structure 51, and the third filtering structure can filter the sewage entering the water suction pump 4.
[0058] Further, a water suction pump mounting seat 5 is disposed in the second chamber 12. The water suction pump mounting seat 5 is a hollow structure with a side opening on the side. The water suction pump 4 is disposed on the water suction pump mounting seat 5 and the water suction end of the water suction pump 4 extends into the water suction pump mounting seat 5.
[0059] Specifically, as Figure 1 shown, in this embodiment, a water suction pump mounting seat 5 is further disposed in the second chamber 12. It can be understood that the water suction pump mounting seat 5 is a cube structure. The bottom surface of the water suction pump mounting seat 5 is fixedly disposed on the bottom plate of the corresponding accommodation cavity 1 of the second chamber 12, and openings are provided on the other several surfaces. The water suction pump 4 is fixedly disposed on the water suction pump mounting seat 5, and the water suction end of the water suction pump 4 can extend into the water suction pump mounting seat 5 from any surface other than the bottom surface. The third filtering structure 51 is disposed at the remaining side openings of the water suction pump mounting seat 5. By disposing the third filtering structure 51 on the side of the water suction pump mounting seat 5, the area of the third filtering structure 51 can be increased, which can further improve the sewage treatment efficiency and prevent the impurities in the sewage from damaging the water suction pump 4.
[0060] Of course, in other embodiments, the third filtering structure 51 can also be directly disposed at the water suction end of the water suction pump 4.
[0061] Specifically, in this embodiment, the third filtering structure 51 is a filter screen.
[0062] Optionally, a monitoring component 6 is arranged in the second chamber 12, and the monitoring component 6 can detect the water level in the second chamber 12. It can be understood that arranging the monitoring component 6 in the second chamber 12 to monitor the water level in the second chamber 12. When the sewage in the second chamber 12 reaches a certain height, the water suction pump 4 is started to discharge the sewage in the second chamber 12.
[0063] Optionally, the monitoring component 6 is a liquid level sensor. A liquid level sensor is a pressure sensor for measuring the liquid level. Specifically, in this embodiment, the liquid level sensor is a static pressure input type liquid level transmitter. The static pressure input type liquid level transmitter is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It uses an isolated diffused silicon sensitive element or a ceramic capacitive pressure sensitive sensor to convert the static pressure into an electrical signal, and then through temperature compensation and linear correction, it is converted into a standard electrical signal.
[0064] Furthermore, as Figures 3 to 6 shown, handles 7 are arranged on both the first cover plate 31 and the second cover plate 32.
[0065] Specifically, as Figure 3 and Figure 4 shown, taking the first cover plate 31 as an example, two U-shaped grooves are arranged on the first cover plate 31, and each U-shaped groove is provided with a handle 7. As Figures 3 to 6 shown, the second cover plate 32 is similar in structure to the first cover plate 31, and the only difference between the two is that a second through hole 311 is provided on the first cover plate 31.
[0066] When the first chamber 11 or the second chamber 12 needs to be detected and maintained, the cover plate can be easily opened by pulling up the handle 7 arranged on the corresponding cover plate, which is convenient for the staff to conduct inspections.
[0067] The present utility model also discloses a ship, including the above-mentioned marine sewage well, and the sewage of the ship can enter the first chamber 11.
[0068] Specifically, as Figure 1 shown, the working process of the marine sewage well in this embodiment is as follows:
[0069] First of all, sewage enters the first chamber 11 through a plurality of second through holes 311 on the first cover plate 31. The plurality of second through holes 311 form a second filtering structure that can preliminarily filter the sewage.
[0070] Secondly, after the sewage enters the first chamber 11, it is collected and precipitated in the first chamber 11. When the height of the sewage in the first chamber 11 is higher than the lowest point of the first through hole 21 on the partition plate 2, the sewage in the first chamber 11 can enter the second chamber 12 through the first through hole 21, and the first filtering structure 211 arranged in the first through hole 21 can reprocess the sewage.
[0071] Next, the sewage enters the second chamber 12, where it accumulates and precipitates. When the monitoring component 6 detects that the water level in the second chamber 12 is too high, the water pump 4 installed at the bottom of the second chamber 12 is activated to discharge the sewage in the second chamber 12. Before the sewage in the second chamber 12 enters the water pump 4, it also has to pass through the third filtering structure 51 provided on the water pump mounting base 5, and the third filtering structure 51 processes the sewage once again.
[0072] The above embodiments only illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, there are various changes and modifications to the present invention, and these changes and modifications all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
