DETAILED DESCRIPTION

[0019] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0020] A preferred embodiment of the oil mist box that is easy to clean of the present invention is as follows: Figure 1 and Figure 2 As shown, the oil mist box that is easy to clean includes a box body 1 and a fumigation chamber pipe 2. The box body 1 is the main structure of the oil mist box, and the fumigation chamber pipe 2 is assembled in the box body 1.

[0021] The housing 1 comprises a top plate 11, a bottom plate, and a surrounding plate 13. The top plate 11 is located above and spaced apart from the bottom plate. The surrounding plate 13 is connected between the top and bottom plates. These three plates form an oil mist chamber 14, which temporarily stores the oil mist discharged from the vent pipe 9. The surrounding plate 13 is also provided with a louver 3, which connects the oil mist chamber 14 with the space outside the housing 1. The oil mist in the oil mist chamber 14 can be discharged to the outside through the louver 3, facilitating the free flow of air and promoting the ventilation of oil and water.

[0022] The fumigation tank pipe 2 is fixedly connected to the coaming 13 and communicates with the oil mist chamber 14. The fumigation tank pipe 2 is used to communicate with the steam equipment of the hull to transport steam into the oil mist chamber 14. After the high-temperature steam enters the oil mist chamber 14 through the fumigation tank pipe 2, it can fumigate the grease in the oil mist box, clean the grease in the oil mist box, and improve the cleaning efficiency of the oil mist chamber 14. The fumigation tank pipe 2 has a straight pipe structure and is installed near the top plate 11. The fumigation tank pipe 2 takes up little space. Since it is installed on the coaming 13, the grease is mainly concentrated on the bottom plate under the action of gravity. While facilitating the cleaning of the oil mist box, the presence of the fumigation tank pipe 2 does not affect the cleaning of the oil mist box.

[0023] The top plate 11 is also provided with a plurality of assembly openings 111, each of which is spaced apart. The assembly openings 111 are used to connect to the ventilation pipe 9. There are multiple ventilation pipes 9, and the assembly openings 111 correspond one to one with the ventilation pipes 9. Each ventilation pipe 9 can be connected to the main engine, generator set, fuel tank, lubricating oil tank, etc. Because the ventilation pipe 9 is connected to the top plate 11 of the oil mist box, the ventilation pipe 9 does not need to be inserted into the oil mist chamber 14. This allows the main engine, generator set, fuel tank, and lubricating oil tank to ventilate smoothly, avoids the need to arrange pipes in the oil mist box, and facilitates cleaning. In this embodiment, a backing plate 15 is welded and fixed to the location where the assembly openings 111 are opened on the top plate 11. The assembly openings 111 pass through the backing plate 15, and the backing plate 15 increases the strength of the top plate 11 at the assembly openings 111. The ventilation pipe 9 is welded and fixed to the backing plate 15.

[0024] The oil mist box, which is easy to clean, is provided with an assembly port 111 on the top plate 11 for connecting the air vent pipe 9, that is, connecting the air vent pipe 9 to the top plate 11 of the oil mist box, and the oil mist can enter the oil mist chamber 14 from the top of the oil mist box through the air vent pipe 9. At this time, the air vent pipe 9 does not need to extend into the oil mist chamber 14. The space inside the oil mist chamber is spacious and free of debris, which is convenient for cleaning; at the same time, the enclosure 13 is fixedly connected to the fumigation chamber pipe 2, and the fumigation chamber pipe 2 can transport high-temperature steam into the oil mist chamber 14. The high-temperature steam can fumigate the oil stains in the oil mist box, and the oil stains in the oil mist box can be rinsed clean, which is convenient for the operator to clean the oil mist box.

[0025] Preferably, a flange seat 4 is provided on the side of the enclosure 13 away from the oil mist chamber 14 , one end of the fumigation pipe 2 is fixedly connected to the flange seat 4 , and the other end extends into the oil mist chamber 14 , and a spray hole 21 is provided on the pipe wall of the fumigation pipe 2 .

[0026] A flange seat 4 is provided on the coaming 13 to increase the structural strength of the connection between the coaming 13 and the fumigation chamber pipe 2. The fumigation chamber pipe 2 is welded to the flange seat 4. The fumigation chamber pipe 2 has a spray hole 21 on its wall to limit the direction of the high-temperature steam and improve the fumigation effect.

[0027] Preferably, a plurality of injection holes 21 are provided at intervals along the axial direction of the fumigation chamber pipe 2 , and the injection holes 21 are evenly distributed along the circumference of the fumigation chamber pipe 2 .

[0028] The injection holes 21 are distributed in an array along the fumigation chamber pipe 2 , and high-temperature steam can be ejected from each injection hole 21 in multiple directions, thereby reducing fumigation dead angles and improving fumigation efficiency.

[0029] Preferably, the interval between two adjacent injection holes 21 along the axial direction of the fumigation chamber pipe 2 is 150-250 mm.

[0030] High-temperature steam is affected by temperature and pressure, and the effective flushing area is limited. Setting the interval between two adjacent injection holes 21 to 150-250 mm can increase the number of injection holes 21 and reduce flushing dead angles. In this embodiment, the axial interval between two adjacent injection holes 21 is 200 mm.

[0031] Preferably, a discharge pipe 5 is further included, which is fixedly connected to the bottom plate and communicates with the oil mist chamber 14 .

[0032] The bottom plate is fixedly connected to a drain pipe 5, which is used to discharge the oil and water in the oil mist chamber 14, so as to facilitate emptying the oil mist box in advance during cleaning.

[0033] Preferably, the bottom plate includes a horizontal section and an inclined section 122 connected to the horizontal section. The height of the inclined section 122 close to the horizontal section is lower than the height of the end away from the horizontal section. The discharge pipe 5 is assembled in the horizontal section.

[0034] The bottom plate is formed by an inclined section 122 and a horizontal section. The discharge pipe 5 is arranged in the horizontal section, and the side of the inclined section 122 away from the horizontal section is higher. Under the action of gravity, the oil mist will flow along the inclined section 122 to the horizontal section and gather on the upper side of the discharge pipe 5, making it easier to drain the oil and water in the oil mist box.

[0035] Preferably, a float switch 6 is further included. The float switch 6 is mounted on the enclosure 13 , and the height of the float switch 6 is lower than the height of the blinds 3 .

[0036] When the drain pipe 5 becomes clogged, causing the oil and water levels in the oil mist tank to rise, the level triggers the float switch 6, which provides a timely alarm and facilitates cleaning of the oil mist tank. The float switch 6 is positioned lower than the louver 3. This triggers the alarm before the oil and water levels reach the louver 3. This prevents oil and water from overflowing through the louver 3 and contaminating the hull, facilitating timely cleaning of the oil mist tank. In this embodiment, the coaming 13 is provided with a base plate flange 7, to which the float switch 6 is mounted using stud bolts for easy assembly and disassembly.

[0037] Preferably, the height difference between the float switch 6 and the shutter 3 is in the range of 50-100 mm.

[0038] After the oil and water trigger the float switch 6, the personnel clean the oil mist box and dredge the discharge pipe 5. The height difference range of 50-100 mm can provide sufficient cleaning time for the personnel, and the volume of the oil mist box will not be increased due to excessive height difference.

[0039] Preferably, the coaming 13 includes a hull outer plate 131 and a side plate 132 , the fumigation chamber pipe 2 is connected to the side plate 132 , the shutter 3 is provided on the hull outer plate 131 , and a manhole cover 8 is also mounted on the side plate 132 .

[0040] Using the hull plating 131 as part of the oil mist box's coaming 13 simplifies the box's structure, facilitating ease of manufacture and avoiding unnecessary piping modifications. Louvers 3 are installed on the hull plating 131 to allow oil vapor to be discharged directly outside the vessel, while manhole covers 8 on the side panels 132 facilitate access to the oil mist box for cleaning.

[0041] In summary, the embodiment of the present invention provides an oil mist box that is easy to clean, and an assembly port is provided on the top plate of the oil mist box for connecting a breather pipe, that is, the breather pipe is connected to the top plate of the oil mist box, and the oil mist can enter the oil mist chamber from the top of the oil mist box through the breather pipe. At this time, the breather pipe does not need to extend into the oil mist chamber, and the space inside the oil mist chamber is spacious and free of debris, which is convenient for cleaning; at the same time, the enclosure is fixedly connected to the fumigation chamber pipe, and the fumigation chamber pipe can transport high-temperature steam into the oil mist chamber. The high-temperature steam can fumigate the oil stains in the oil mist box, and the oil stains in the oil mist box can be rinsed clean, which is convenient for the operator to clean the oil mist box.

[0042] The above is only a preferred embodiment of the present invention.
