By providing the adjusting member 14 on the exhaust duct 13 to adjust the air volume discharged from the exhaust duct 13, the vacuum degree in the fuel tank 20 is adjusted, preventing the increase in the air intake of the exhaust oil fume fan 12, avoiding the entry of pollutants such as dust in the air into the fuel tank 20, ensuring the quality of the lubricating oil in the fuel tank 20, and further avoiding accidents. In addition, it can also prevent the sulfur-containing air in the induced draft fan from entering the fuel tank 20 to corrode the fuel tank 20 and extend the service life of the fuel tank 20.

[0038] In some embodiments of the present disclosure, the adjusting member 14 is an adjusting baffle. The adjusting baffle is provided in the exhaust duct 13. By adjusting the gap between the adjusting baffle and the exhaust duct 13, the exhaust volume of the exhaust air duct is adjusted, thereby realizing the adjustment of the vacuum degree in the fuel tank 20.

[0039] In some embodiments of the present disclosure, the adjusting baffle is provided in the exhaust duct 13 in a rotatable manner. By rotating the adjusting baffle, the gap between the adjusting baffle and the exhaust duct 13 can be adjusted, thereby adjusting the exhaust volume of the exhaust pipe.

Specifically, each pressing plate 1122 is provided with a plurality of through holes to ensure that gas can enter the filter net 1121 from the baffle on one side of the filter net 1121 and be discharged from the baffle on the other side of the filter net 1121. By providing the two baffles, the firmness of the filter element 112 can be improved.

[0047] In some embodiments of the present disclosure, the filter net 1121 is a metal filter net 1121, and the metal filter net 1121 can be used to filter the oil mist in the gas and reduce the loss of oil. In some embodiments of the present disclosure, the thickness range of the filter net 1121 in the direction from the air inlet 102 to the exhaust port 103 is 80 mm to 120 mm.
