Description

Technical Field

[0001] The utility model belongs to the field of ship ballast water drainage, and particularly relates to a drainage pipeline structure of a ballast water tank. Background Art

[0002] The ballast water tank is an essential liquid tank in a ship, which is filled with seawater to adjust the ship's stability when the ship is running and operating. Usually, a large area of ​​the hull is exposed above the water, which is easily attacked by wind and waves. If the center of gravity is too high, the ship will shake violently, and may even capsize in serious cases. In order to maintain the balance of the hull, the draft of the ship must be increased to lower its center of gravity. At present, the purpose of lowering the center of gravity of the ship is usually achieved by directly sucking seawater into the ballast tank of the hull through a pumping head as the main carrier of the ship's ballast, and ballast water comes from this.

[0003] The filters on the market cannot clean the stains on the filter in time when cleaning the ballast water. Some automatic filter cleaning devices use a brush head. When cleaning the stains on the filter, the stains will still remain in the filter. As the next ballast water flows over, the stains will still be adsorbed on the filter. Long-term accumulation will cause the filter to be blocked and the stains will flow into the water tank, causing the dirt in the water tank to settle and affect the environment inside the water tank.

[0009] As a preferred technical solution, two dust collector heads are fixedly connected to one end of the rotating column, and the length of the dust collector heads is consistent with the filter screen.

[0010] As a preferred technical solution, the filter is cylindrical, the rotating column and the dust collector head are both arranged inside the filter, and the dust collector head is closely connected to the inside of the filter.

[0025] The filter 4 includes a motor 13, an exhaust fan 10 housing 41, a storage box 14, a filter 11, a rotating column 15, a dust head 12 and an exhaust pipe 5. The motor 13 is fixedly installed at the bottom of the filter 4 housing 41, and the exhaust pipe 5 is fixedly installed at one end of the housing 41 away from the motor 13. The exhaust pipe 5 is fixedly connected with a solenoid valve 20, and an exhaust channel 19 is opened inside the exhaust pipe 5. One end of the exhaust pipe 5 is fixedly connected with the storage box 14, and one side of the storage box 14 is fixedly connected with the exhaust fan 10 through the exhaust pipe 5. The filter 11, the rotating column 15 and the dust head 12 are fixedly installed inside the housing 41. The same exhaust channel 19 as the exhaust pipe 5 is opened in the rotating column 15 and the dust head 12, and a blocking net 22 is slidably connected inside the storage box 14.

[0026] refer to Figures 2 to 3 The output shaft of the motor 13 passes through the bottom of the shell and is welded to the internal rotating column 15, so that the output shaft of the motor 13 can drive the rotating column 15 to rotate, so that the dust removal head can fully clean the filter screen 11. One end of the rotating column 15 is fixedly connected with two dust suction heads 12. The dust suction head 12 is set to be rectangular and the height is consistent with the filter screen 11. It can fully clean the stains on the filter screen 11 and will not leave stains on the filter screen 11 to cause the ballast water to stagnate. The filter screen 11 is cylindrical. The rotating column 15 and the dust suction head 12 are both arranged inside the filter screen 11. The vacuum head 12 is tightly connected to the inside of the filter 11. The filter 11 is set to be barrel-shaped for convenience in cleaning. The vacuum head 12 can be rotated inside the cylinder to clean the filter 11 for a long time, and the stains can also be cleaned without dead ends. A blocking net 22 is slidably installed inside the side of the storage box 14. A handle 23 is provided at one end of the blocking net 22 to prevent the sucked stains from running into the exhaust fan 10, which can maintain the normal operation of the exhaust fan 10. The blocking net 22 can be replaced by pulling out the handle 23, which can increase the speed of replacing the blocking net 22 and improve convenience.

[0027] refer to Figures 1 to 3 A bearing 17 is fixedly installed inside one end of the exhaust pipe 5, and the upper end of the rotating column 15 is rotatably connected to the exhaust pipe 5 through the bearing 17, so that the rotating column 15 can be connected to the exhaust pipe 5, and the stains can be removed to the blocking net 22 for easy removal of the stains. The connection between the first drainage pipe 2 and the rectangular tube 18 forms a "T" shape, and the connection between the second drainage pipe 8 and the rectangular tube 18 also forms a "T" shape, which can make the first drainage pipe 2 and the second drainage pipe 8 communicate with each other, so that the ballast water is counted from the first drainage pipe 2 into the rectangular tube 18 to filter out the stains and then discharged from the second drainage pipe 8 to the hull.

[0028] Principle and advantages of use: When the water pump 3 is turned on, the ballast water will flow into the first drainage pipe 2 along the water pumping port, and the ballast water will flow into the rectangular tube 18 along the first drainage pipe 2. The ballast water will enter the filter 4 through the rectangular tube 18 to filter the ballast water. The filtered ballast water will flow into the second drainage pipe 8 and be discharged from the hull. The filter 11 inside the filter 4 intercepts the stains in the ballast water. Since the stains remain on the filter 11 for a long time, the filter 11 will be blocked. If it is not cleaned in time, when the next ballast water flows over, the filter 11 will be blocked. If the ballast water cannot be discharged in time, it is easy to cause the failure of the filter 4. For this reason, a structure that can clean the residual stains on the filter 11 is installed. The structure for cleaning the filter 11 consists of a motor 13, a rotating column 15, a dust collector head 12, an exhaust pipe 5 and an exhaust fan 10. The motor 13 is installed at the bottom of the shell, but the output shaft runs through the inside. If the ballast water is filtered inside the shell, the water may flow into the inside of the motor 13 along the output shaft of the motor 13, which will cause great danger. Therefore, a rotary seal is installed at the position where the output shaft and the shell pass through. The motor 13 is circled so that water will not flow into the motor 13. The output shaft of the motor 13 is fixed at the bottom of the rotating column 15. When the output shaft rotates, the rotating column 15 will rotate along the output shaft. A dust collector 12 is fixedly installed at one end of the rotating column 15. The rotating column 15 drives the dust collector 12 to be fully cleaned. The upper end of the rotating column 15 passes through the shell and is rotatably connected to the exhaust pipe 5. A solenoid valve 20 is fixedly installed on a section of the exhaust pipe 5. When the ballast water enters the filter 4, the water pressure will flow upward along the exhaust pipe. 5 entering the exhaust fan 10 will also bring danger, so the solenoid valve 20 can effectively prevent water from entering the exhaust fan 10. A storage box 14 is fixedly installed at one end of the exhaust pipe 5. The storage box 14 is slidably connected to the inside of the storage box 14. The blocking net 22 will block the dirt sucked in by the exhaust fan 10. The blocking net 22 can be moved by the handle 23 to replace the blocking net 22, which improves the cleanliness of the filter 11 and is convenient for cleaning the dirt reasonably, thereby improving the utilization rate of the filter 11 and meeting the discharge standard when discharging ballast water.
