Description

Technical Field

[0001] The utility model relates to the technical field of pipeline degassing, in particular to a ballast water degassing device. Background Art

[0002] In ships, a ballast water system is used to adjust the buoyancy of the ship. The function of the ballast water system is to inject ballast water into the ballast tank or discharge ballast water from the ballast tank, so as to achieve the following purposes: the ship maintains appropriate displacement, draft, longitudinal and transverse balance of the hull under different working conditions such as navigation, entering and leaving the port, loading and unloading, and anchoring, so as to maintain an appropriate metacentric height, reduce excessive bending moment and shear force of the hull, and alleviate the vibration of the hull.

[0003] When injecting ballast water, if gas appears at a high point in the pipeline transporting ballast water, it is easy to restrict the flow of liquid, slow down the injection rate of ballast water, and reduce the ballast water injection efficiency. In addition, the air in the pipeline will also cause hydraulic instability in the system, thereby affecting the operation of the ship. Summary of the invention

[0004] In view of this, the purpose of the utility model is to provide a ballast water degassing device to solve the problem that pipeline gas affects the operation of the ship.

[0005] Based on the above-mentioned purpose, the utility model provides a ballast water degassing device, including a box body arranged on the top of a pipeline equipped with ballast water, a heating jacket arranged on one side of the box body and sleeved on the pipeline, a accommodating cavity arranged in the box body, an exhaust port arranged on the upper side wall of the box body, an exhaust pipe connected with the exhaust port and even connected with the outside air arranged in the box body, a movable pipe slidably connected in the exhaust pipe, the movable pipe moves axially along the exhaust pipe, a plurality of exhaust holes are arranged on the upper part of the movable pipe, a rubber pad located on one side of the exhaust port is arranged at the end of the movable pipe away from the exhaust port, a float is arranged in the box body, and the float is connected to the end of the movable pipe away from the exhaust port through a traction elastic member.

[0006] Optionally, an inclined rail is provided in the box, the upper end of the inclined rail is closer to the side of the box where the exhaust port is provided than the lower end of the inclined rail, and a slider fixedly connected to the float is slidably connected to the inclined rail.

[0007] Optionally, an annular scraper is provided at one end of the exhaust pipe away from the exhaust port, and the annular scraper is provided in contact with the outer side wall of the movable pipe.

[0008] Optionally, the traction elastic member is an elastic spring or an elastic rubber rod.

[0009] Optionally, the exhaust pipe is arranged obliquely, and the height of one end of the exhaust pipe connected to the exhaust port is higher than the other end of the exhaust pipe.

[0010] Optionally, at least one sliding groove is formed on the inner side wall of the exhaust pipe, and a sliding block fixedly connected to the outer side wall of the movable pipe is slidably connected in the sliding groove.

[0011] The beneficial effects of the utility model are as follows: the utility model provides a ballast water degassing device. When ballast water is transported in a pipeline, the heating jacket heats the water in the pipeline. The water in the pipeline expands after heating, and water vapor moves upward. The expanded water vapor drives the gas in the pipeline to be discharged into the accommodating cavity in the box body, and then enters the moving pipe through the exhaust hole, and then is discharged from the box body through the exhaust port, thereby realizing the discharge of gas in the pipeline. In this way, the flow of liquid is no longer restricted, and the pipeline can discharge water normally, thereby improving the use efficiency of the pipeline and reducing energy consumption, increasing the circulation rate of ballast water, removing the air in the pipeline, and improving the stability of the pipeline hydraulic pressure, thereby ensuring the operation of the ship.

[0019] like Figure 1 , Figure 2 As shown, a ballast water degassing device comprises a box body 2 arranged on the top of a pipe 1 equipped with ballast water, a heating jacket 3 arranged on one side of the box body 2 and sleeved on the pipe 1, a accommodating cavity is arranged in the box body 2, an exhaust port is opened on the upper side wall of the box body 2, an exhaust pipe 4 connected with the exhaust port and even connected with the outside air is arranged in the box body 2, a movable pipe 5 is slidably connected in the exhaust pipe 4, the movable pipe 5 moves axially along the exhaust pipe 4, a plurality of exhaust holes 6 are opened on the upper part of the movable pipe 5, a rubber pad 8 located on one side of the exhaust port is arranged at one end of the movable pipe 5 away from the exhaust port, a float 9 is arranged in the box body 2, and the float 9 is connected to the end of the movable pipe 5 away from the exhaust port through a traction elastic member 7.

[0020] When ballast water is transported in the pipeline 1, the heating jacket 3 heats the water in the pipeline 1. The water in the pipeline 1 expands after heating up, and the water expands into water vapor and moves upward. The expanded water vapor and the gas in the pipeline 1 are discharged into the accommodating cavity in the box 2, and then discharged from the box 2 through the exhaust hole 6 on the mobile pipe 5, the mobile pipe 5 and the exhaust port in turn, so that the gas in the pipeline 1 is discharged from the pipeline 1. In this way, the flow of liquid is no longer restricted, the pipeline 1 can discharge water normally, and the circulation rate of ballast water is increased. In addition, the air in the pipeline 1 is removed cleanly, and the hydraulic stability of the pipeline 1 is improved, thereby ensuring the operation of the ship, improving the use efficiency of the pipeline 1 and reducing energy consumption.

[0021] An inclined rail 10 is arranged in the box body 2, and the upper end of the inclined rail 10 is closer to the side of the box body 2 where the exhaust port is arranged than the lower end of the inclined rail 10. A slider fixedly connected to the float 9 is slidably connected to the inclined rail 10. The arrangement of the inclined rail 10 facilitates the float 9 to move closer to the exhaust pipe 4 after water rises in the box body 2, thereby accelerating the efficiency of the moving pipe 5 entering the exhaust pipe 4 and preventing water from being discharged to the outside of the box body 2 through the exhaust hole 6 on the moving pipe 5.

[0022] An annular scraper 11 is provided at one end of the exhaust pipe 4 away from the exhaust port. The annular scraper 11 is provided in contact with the outer wall of the movable pipe 5 . When the movable pipe 5 moves along the axis of the exhaust pipe 4 , the annular scraper 11 scrapes impurities on the outer wall of the movable pipe 5 .

[0023] The traction elastic member 7 can be an elastic spring or an elastic rubber rod, and the traction elastic member 7 is used for elastic connection between the float 9 and the moving tube 5 for quality inspection.

[0024] A heating pad is provided in the heating jacket 3, and the heating pad is connected to a power source provided on the box 2. In order to heat the pipe 1, the water in the pipe 1 expands, and the water vapor flies upward to drive the air in the pipe 1 to flow into the box 2 and then be discharged.

[0025] In order to facilitate the movable tube 5 to move smoothly into the exhaust pipe 4 after the float 9 floats up, thereby accelerating the exhaust hole 6 to be blocked by the exhaust pipe 4 and reducing the risk of water flowing out of the pipeline 1, the exhaust pipe 4 is tilted, and the height of one end of the exhaust pipe 4 connected to the exhaust port is higher than that of the other end of the exhaust pipe 4. The exhaust pipe 4 is tilted to accelerate the collection of the movable tube 5 into the exhaust pipe 4.

[0026] At least one sliding groove is formed on the inner wall of the exhaust pipe 4 , and a sliding block fixedly connected to the outer wall of the movable pipe 5 is slidably connected in the sliding groove. The exhaust pipe 4 is slidably connected to the movable pipe 5 , which reduces the probability of the movable pipe 5 detaching from the exhaust pipe 4 .

[0027] A person skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
