These pipes may be responsible for discharging mixed sewage containing soda and water, such as bilge water and flushing wastewater, overboard to prevent sewage accumulation within the vessel and ensure the cleanliness and hygiene of the vessel. Mixed soda and water pipes typically involve more advanced sewage treatment technologies, which can more effectively remove harmful substances in the sewage, such as COD, BOD, nitrogen oxides, and sulfur oxides, significantly reducing pollution to the environment.
[0003] Sewage drain pipes are generally located at the bottom of the ship, below the water level. When sewage is not being discharged, the sewage drain pipes are in an open state, which can easily cause water backflow and bring in some non-degradable marine debris or some marine organisms, causing blockage in the sewage drain pipes and affecting sewage discharge. Utility Model Content

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.
[0020] like Figures 1 to 5As shown, an embodiment of the present invention proposes a soda-water mixed sewage pipe, which includes a pipe body 1, an air inlet 102 formed at one end, a sewage outlet 104 formed at the other end, and a water inlet 101 is provided on the peripheral side of one end of the pipe body 1 close to the air inlet 102; a protective device includes a protective plate 2 rotatably arranged in the pipe body 1 and a vent member fixedly arranged in the pipe body 1, the vent member includes a mounting plate 3 fixedly arranged in the pipe body 1 and having multiple groups of through grooves 301 thereon, and a baffle 302 hingedly connected with a number corresponding to the through grooves 301, each baffle 302 covering a corresponding through groove 301, wherein the protective plate 2 is located between the sewage outlet 104 and the water inlet 101, and is used to prevent sewage from backflowing, and the vent member is used to prevent sewage from entering the air inlet 102.
[0021] The detailed working process of this embodiment is as follows: the air inlet 102 is connected to the air outlet device in the ship, the water inlet 101 is connected to the drainage device in the ship, and the sewage and gas are mixed in the pipe body 1 and discharged from the sewage outlet 104.
[0022] By setting the protective plate 2 and the vent in the protective device, the backflow of seawater is blocked to prevent the backflow of seawater from carrying various objects into the pipeline and causing blockage of the water inlet 101 and the air inlet 102. During the drainage process, the impact force of the mixture of steam and water will open the protective plate 2 and the baffles 302, and the sewage will be discharged. When there is no need to discharge sewage, the protective plate 2 and the baffles 302 return to their initial positions under their own gravity, closing the pipeline. When the water flows back, it is blocked by the protective plate 2 and the baffles 302, which can prevent external water from entering the water inlet 101 and the air inlet 102 and causing blockage.
[0023] like Figure 3 As shown, the protective plate 2 is elliptical and tilted and is rotatably arranged in the tube body 1. The angle between the protective plate 2 and the axis of the tube body 1 is 55° to 65°.
[0024] The detailed working process of this embodiment is as follows: the protective plate 2 is tilted in an elliptical shape and is rotatably arranged in the pipe body 1. Within a certain range, the larger the tilt angle, the smaller the resistance when discharging sewage. In this embodiment, the tilt angle of the protective plate 2 is 55 degrees. In actual situations, a suitable tilt angle can be selected according to the pipe diameter.
[0025] like Figure 2 As shown, a guide groove 201 is provided on one side of the protection plate 2 away from the sewage outlet 104 .
[0026] The detailed working process of this embodiment is as follows: the protective plate 2 is in a closed state with the pipeline in its original state. When sewage is discharged, when the sewage contacts the protective plate 2, under the action of the guide groove 201, the sewage flows through the guide groove 201 to one end of the protective plate 2 and pushes it open, making it open to facilitate sewage discharge. After the sewage is discharged, the protective plate 2 is in a stationary state. When water flows back, the backflowing water flow impacts the stationary protective plate 2, and the protective plate 2 is forced to rotate, separating the pipeline, completing the blocking task, and preventing continuous backflow of water.
[0027] like Figure 3 As shown, two limit blocks 202 are mirror-imaged on the inner wall of the tube body 1 , and both limit blocks 202 are located between the protective plate 2 and the water inlet 101 . The protective plate 2 can abut against the two limit blocks 202 when rotating.
[0028] The detailed working process of this embodiment is as follows: the function of the two limit blocks 202 is to limit the protective plate 2 to prevent the protective plate 2 from rotating to an inverted state, so that the protective plate 2 blocks in the reverse direction, resulting in the sewage inside the ship being blocked by the protective plate 2 when being discharged, and the backflowing water flows into the inside of the pipe.
[0029] like Figure 4 and Figure 5 As shown, a first partition plate 3011 and a second partition plate 3012 are respectively provided at the upper and lower ends of the side of each through groove 301 close to the air inlet 102, and a first notch 3021 and a second notch 3022 are respectively opened at the upper and lower ends of the side of each baffle plate 302 close to the mounting plate 3. When the corresponding baffle plate 302 is in the original state, the first partition plate 3011 abuts against the first notch 3021, and the second partition plate 3012 abuts against the second notch 3022.
[0030] The detailed working process of this embodiment is as follows: in the initial state, the baffle 302 is located in the through groove 301. Under the setting of the first partition 3011 and the second partition 3012, the baffle 302 is limited to prevent the baffle 302 from rotating in the opposite direction and causing reverse obstruction, resulting in gas discharge being blocked. In the original state, the baffle 302 is located in the through groove 301. When sewage flows back, the baffle 302 blocks it, thereby preventing the water source from passing through the mounting plate 3 and entering the air inlet 102. When jetting, the baffle 302 is lifted by the airflow to open the through groove 301, and the gas passes through the through groove 301 into the tube body 1 and mixes with the sewage.
[0031] like Figure 5 As shown, in the open state, each baffle 302 forms an angle of 80° with the mounting plate 3 .
[0032] The detailed working process of this embodiment is as follows: the angle between the lower part of the baffle 302 and the mounting plate 3 when in the open state needs to be less than 90 degrees. Since the pipe body 1 is located below the water level line, the pipe body 1 is filled with water. When water backflow occurs, the backflowing water flows into the through groove 301 and at the same time flushes the mounting plate 3 back into the through groove 301, blocking the through groove 301 and completing the barrier.
[0033] In this embodiment, the included angle between the baffle 302 and the mounting plate 3 in the open state is 80°. In other embodiments, the baffle 302 can be rotated to a suitable angle according to actual conditions.
[0034] like Figure 1 As shown, a plurality of spiral rails 1041 are provided at the end of the sewage outlet 104 of the pipe body 1 .
[0035] The detailed working process of this embodiment is as follows: the function of the multiple sets of spiral rails 1041 is to reduce the noise when sewage is discharged from the pipe body 1, reduce the direct impact between the water flow and the pipe wall, and thus reduce the generation of noise.
[0036] The working principle of the embodiment of the present application is as follows: the air inlet 102 is connected to the air outlet device in the ship, the water inlet 101 is connected to the drainage device in the ship, the sewage and gas are mixed in the pipe body 1 and discharged from the sewage outlet 104;
[0037] When water backflow occurs, the protection plate 2 and the baffle 302 are forced to rotate, the protection plate 2 separates the pipes, and the baffles 302 close the through grooves 301, thereby preventing water backflow from causing blockage.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
