The discharge of foul-smelling gases from sewage and the discharge of sewage usually require separate motor drives, i.e., the blower is driven by one motor and the sewage transfer pump is driven by another motor, which does not meet the design requirements of compact and low-energy consumption for ship equipment.

The top middle of the sewage tank 1 is fixedly connected to the exhaust pipe 35. One end of the exhaust pipe 35 is fixedly connected to the air purifier 36. The gas discharged from the exhaust port is transmitted to the air purifier 36 through the exhaust pipe 35 for purification and then discharged.

[0022] Working principle: Shipboard sewage enters the sewage tank 1 through the inlet pipe 8. Simultaneously, the second motor 23 drives the first connecting column 24, which in turn rotates the third bevel gear 25. This rotation is transmitted via the fourth bevel gear 37 to the second connecting column 26, causing the second connecting column 26 to rotate on the second support plate 30. The first gear 27 on the outer ring of the second connecting column 26 meshes with the first gear 27 at the bottom of the blade rod 31, driving the blade rod 31 to rotate and generating an upward airflow. This airflow draws out unpleasant gases such as hydrogen sulfide and ammonia from the sewage tank 1 through the top exhaust vent, and then sends them through the exhaust pipe 35 to the air purifier 36 for purification before being discharged, preventing the spread of odors. At the same time, the second gear 28 at the bottom of the second connecting column 26... Engaging with the third gear 32 at the top of the spiral blade rod 33, the spiral blade rod 33 rotates on the first support plate 29, pushing the impurities settled at the bottom of the sewage tank 1 to prevent the sewage pipe from being blocked, and transporting them to the filter box 3. After entering the filter box 3, the sewage flows through three layers of filter plates 9 under its own gravity: the top layer of coarse screen intercepts large impurities such as food scraps and hair clumps; the middle layer uses media such as quartz sand, activated carbon, and fiber filter cloth to adsorb organic matter, pigments, and some dissolved impurities; the bottom layer of high-precision filter screen further intercepts fine particles such as micron-sized silt, completing physical purification. The filter plate 9 is magnetically fixed to the stainless steel filter box 3 by the end magnet 17 to resist the swaying of the hull and prevent accidental slippage. It can also be manually pulled out for replacement. When impurities accumulate on the surface of the filter plate 9 and affect the filtration efficiency, the sewage entering the sewage tank 1 is stopped. Then, the first motor 22 is started to drive the transmission assembly: the first motor 22 drives the worm gear 14 to rotate, the worm gear 14 meshes with all the worm wheels 13, and synchronously drives the second bevel gear 15 to rotate; the second bevel gear 15 meshes with the first bevel gear 12, driving the lead screw 10 to rotate, so that the threaded slider 18 moves smoothly along the guide post 11; the brush 20 at the bottom of the slider 18 sweeps the surface of the filter plate 9, and the scraper 19 pushes the impurities to the sewage outlet at the other end of the filter box 3. After sliding upward through the sealing plate 21, the impurities fall into the pre-placed collection container, thus cleaning the filter plate 9. The water filtered through multiple layers is transported to the water tank 6 through the drain pipe 4, sewage pump 5, and connecting pipe 7. The ultraviolet lamp in the water tank 6 performs deep sterilization on the water, destroying the DNA structure of microorganisms and ensuring water quality safety.
