Structure of a ship ballast water filter

Abstract

This invention discloses the structure of a ship ballast water filter, including a housing. A main filter barrel and a secondary filter barrel are disposed within the housing. An inlet pipe and an outlet pipe are also provided on the housing. The main and secondary filter barrels are arranged side-by-side, have identical structures, and their positions are interchangeable. The inlet pipe, the main filter barrel, and the outlet pipe form a ballast water flow channel. During use, ballast water enters the housing through the inlet pipe, is filtered by the main filter barrel, and is then discharged through the outlet pipe. Larger impurities in the ballast water are filtered out by the filter plates, accumulating on them. When a certain amount of impurities accumulates, the main and secondary filter barrels can rotate, causing the main filter barrel to rotate to one side. Then, personnel can clean the impurities from the filter plates inside the main filter barrel for user convenience. This process eliminates the need for additional disassembly work by personnel.

Description

Technical Field

[0001] This invention belongs to the field of ballast water treatment technology, specifically the structure of a ship ballast water filter. Background Technology

[0002] Ballast water systems play a crucial role in shipbuilding, industry, and other related fields, serving purposes such as regulating ship stability, balancing cargo weight, and acting as cooling water. However, during ballast water filtration, especially after prolonged use, larger impurities gradually accumulate on the filters or screens, forming stubborn deposits. These larger impurities can originate from various sources, such as sediments, suspended particles, and biological debris from rivers and oceans. When ballast water passes through these areas, these impurities are drawn in and carried into the ballast water system. In the initial filtration stage, most impurities are captured by the screens or filters, but over time, these impurities gradually accumulate, forming a thick layer of deposits.

[0003] This buildup not only reduces the filtration efficiency of filters but can also obstruct water flow, thus affecting the normal operation of the entire ballast water system. More seriously, if left uncleaned for a long time, these impurities can breed bacteria, algae, or other microorganisms, polluting the water and threatening the normal operation of ships or industrial equipment.

[0004] Traditional cleaning methods for this problem require manual disassembly of the filter or screen for thorough cleaning and replacement. This not only consumes a significant amount of manpower and time but can also damage the equipment due to improper operation. Furthermore, frequent disassembly and replacement of filters increases the system's maintenance costs. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a structure for a ship ballast water filter, which effectively solves the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a structure for a ship ballast water filter, comprising a housing, within which a main filter barrel and a secondary filter barrel are disposed, and an inlet pipe and an outlet pipe are also disposed on the housing. The main filter barrel and the secondary filter barrel are arranged side by side, have the same structure, and their positions can be interchanged. The inlet pipe, the main filter barrel, and the outlet pipe form a ballast water flow channel.

[0007] An inclined ring plate is installed inside the outer casing. The upper surface of the inclined ring plate is a smooth curved surface, and the inclined ring plate has a highest point and a lowest point. The main filter barrel corresponds to the highest point, and the secondary filter barrel corresponds to the lowest point of the inclined ring plate.

The sliding groove is vertically oriented and the lower end of the sliding groove is open. The bracket passes through the sliding groove and can slide inside the sliding groove. The bracket rests on an inclined ring plate.

[0009] Preferably, a motor is installed on the housing, the output shaft of the motor extends into the housing, and a fixing frame is fixedly connected to the end of the output shaft. The fixing frame is fixedly connected to the main filter barrel and the auxiliary filter barrel respectively, and the main filter barrel and the auxiliary filter barrel are arranged symmetrically about the output shaft, so that the main filter barrel and the auxiliary filter barrel can rotate around the output shaft when the motor is running.

The first groove is connected to the water outlet pipe, and the side wall of the second groove is provided with an outlet that is connected to the outside of the outer casing. The filter plate can enter the second groove along the outlet. A notch is provided on the inclined ring plate, and the filter plate can pass through the inclined ring plate along the notch and move to the top of the inclined ring plate.

[0011] Preferably, a top plate is provided in the second groove, a spring is installed at the lower end of the top plate, and a telescopic component is also installed in the outer shell. One end of a connecting rope is fixed to the telescopic end of the telescopic component, and the other end of the connecting rope is connected to the top plate, so that when the telescopic component is shortened, the connecting rope can pull the top plate downward and compress the spring.

[0012] Preferably, a rotating wheel is provided inside the top plate, and a torsion spring is provided outside the rotating wheel. The end of the connecting rope away from the telescopic member is wrapped around the rotating wheel, so that the telescopic member can continue to move after the top plate is pulled into the limit position.

[0013] Preferably, an end block is fixed to the free end of the telescopic member, a first rotatable gear is provided on the inner wall of the outer shell, and a second gear is provided inside the top plate. The first gear meshes with the second gear, and a rack is provided on the end block. The rack meshes with the first gear, and the upper end of the second gear extends beyond the upper surface of the top plate. When the top plate is pulled to its limit position, the rack on the end block can engage with the first gear.

[0014] Preferably, it also includes a first control module and a second control module. The first control module is used to control the start and stop of the motor, and the second control module is used to control the extension and retraction of the telescopic component. A pressure sensing module is provided at the highest point of the inclined ring plate. A threshold is set in the pressure sensing module.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] Depend on Figure 1-5 This invention discloses a structure for a ship ballast water filter, comprising a housing 1, within which a main filter barrel 3 and a secondary filter barrel 7 are disposed. An inlet pipe 2 and an outlet pipe 4 are also provided on the housing 1. The main filter barrel 3 and the secondary filter barrel 7 are arranged side-by-side, have identical structures, and their positions are interchangeable. The inlet pipe 2, the main filter barrel 3, and the outlet pipe 4 form a ballast water flow channel.

[0026] An inclined ring plate 6 is provided inside the outer casing 1. The upper surface of the inclined ring plate 6 is a smooth curved surface, and the inclined ring plate 6 has a highest point and a lowest point. The main filter barrel 3 corresponds to the highest point, and the secondary filter barrel 7 corresponds to the lowest point of the inclined ring plate 6.

[0027] A filter plate 5 is installed inside the main filter barrel 3. A bracket 15 is fixed to the side wall of the filter plate 5. A sliding groove 14 is opened on the inner wall of the main filter barrel 3. The sliding groove 14 is arranged vertically and the lower end of the sliding groove 14 is open. The bracket 15 passes through the sliding groove 14 and can slide inside the sliding groove 14. The bracket 15 rests on the inclined ring plate 6.

[0028] During the use of this device, ballast water enters the outer casing 1 through the inlet pipe 2, is filtered by the main filter barrel 3, and is discharged through the outlet pipe 4. Larger impurities in the ballast water are filtered out by the filter plate 5, and these larger impurities accumulate on the filter plate 5. When a certain amount accumulates, the main filter barrel 3 and the auxiliary filter barrel 7 can rotate, causing the main filter barrel 3 to rotate to one side. Then, the staff can clean the impurities on the filter plate 5 inside the main filter barrel 3 for the user's use. Moreover, during this process, no additional disassembly work is required from the staff.

[0029] To enable the main filter barrel 3 and the auxiliary filter barrel 7 to rotate, the following technical solution is provided: a motor 8 is installed on the outer casing 1, the output shaft 9 of the motor 8 extends into the outer casing 1, and a fixing frame 10 is fixedly connected to the end of the output shaft 9. The fixing frame 10 is fixedly connected to the main filter barrel 3 and the auxiliary filter barrel 7 respectively, and the main filter barrel 3 and the auxiliary filter barrel 7 are arranged symmetrically about the output shaft 9 as the axis, so that when the motor 8 is running, the main filter barrel 3 and the auxiliary filter barrel 7 can rotate around the output shaft 9, thereby changing their positions and achieving the purpose of alternating use.

[0030] The lower inner wall of the outer casing 1 is provided with a first groove and a second groove. The first groove is connected to the water outlet pipe 4. The side wall of the second groove is provided with an outlet 13, which is connected to the outside of the outer casing 1. The filter plate 5 can enter the second groove along the outlet 13. In order to make the filter plate 5 easy to disassemble and replace, a notch is provided on the inclined ring plate 6. The filter plate 5 can pass through the inclined ring plate 6 along the notch and move to the top of the inclined ring plate 6.

[0031] A top plate 11 is provided in the second groove. A spring 12 is installed at the lower end of the top plate 11. A telescopic member 16 is also installed in the outer casing 1. One end of a connecting rope 20 is fixed to the telescopic end of the telescopic member 16. The other end of the connecting rope 20 is connected to the top plate 11 so that when the telescopic member 16 is shortened, the connecting rope 20 can pull the top plate 11 downward and compress the spring 12.

[0032] A rotating wheel 19 is provided inside the top plate 11, and a torsion spring 22 is provided outside the rotating wheel 19. The end of the connecting rope 20 away from the telescopic member 16 is wrapped around the rotating wheel 19 so that the telescopic member 16 can continue to move after pulling the top plate 11 to the limit position.

[0033] An end block 17 is fixed to the free end of the telescopic member 16. A first gear 21 that can rotate is also provided on the inner wall of the outer shell 1. A second gear 23 is also provided inside the top plate 11. The first gear 21 and the second gear 23 mesh. A rack is provided on the end block 17. The rack meshes with the first gear 21. The upper end of the second gear 23 extends beyond the upper end face of the top plate 11. When the top plate 11 is pulled to the limit position, the rack on the end block 17 can engage with the first gear 21.

[0034] It also includes a first control module and a second control module. The first control module is used to control the start and stop of the motor 8, and the second control module is used to control the extension and retraction of the telescopic component 16. A pressure sensing module is set at the highest point of the inclined ring plate 6. A threshold is set in the pressure sensing module. When the pressure value sensed by the pressure sensing module is greater than the threshold, the first control module can control the motor 8 to make the main filter barrel 3 and the auxiliary filter barrel 7 rotate. And when the output shaft 9 of the motor 8 rotates 180 degrees, the second control module can control the telescopic component 16 to shorten.

[0035] During the use of this device, when the filter plate 5 inside the main filter barrel 3 needs to be disassembled, the motor 8 can run, so that the positions of the main filter barrel 3 and the auxiliary filter barrel 7 are swapped. When the main filter barrel 3 moves from the highest point to the lowest point of the inclined ring plate 6, the filter plate 5 inside the main filter barrel 3 can fall along the notch (at this time it has not yet fallen). Then the telescopic member 16 shortens, and the telescopic member 16 pulls the top plate 11 downward. The filter plate 5 inside the main filter barrel 3 moves downward under its own weight. When the top plate 11 falls to the lowest point, the telescopic member 16 can continue to shorten. At this time, the first gear 21 and the second gear 23 rotate. The rotation of the second gear 23 can push the filter plate 5 inside the main filter barrel 3 outward, so that the filter plate 5 inside the main filter barrel 3 extends outside the outer shell 1. At this time, the user can take it out for cleaning.

[0036] When installing the filter plate 5, the user only needs to push the filter plate 5 into the housing 1 along the outlet 13. Then the telescopic member 16 extends, so that the filter plate 5 is first pushed inward, and then the spring 12 pushes it upward. When the motor 8 is running, the bracket 15 on the outside of the filter plate 5 can slide on the inclined ring plate 6, so that the filter plate 5 can be installed in the main filter barrel 3 or the auxiliary filter barrel 7.
