Description

Technical Field

[0001] The invention belongs to the technical field of ship ballast water treatment, and in particular relates to a ship ballast water ultraviolet treatment device and a treatment method. Background Art

[0002] Ship ballast water is water that ships deliberately carry in order to control their own draft, heel and trim, and other navigation postures. When a ship is unloaded or lightly loaded, it is easy to become unstable, such as top-heavy, due to the light weight of the upper part of the hull. At this time, ballast water needs to be injected to increase the weight of the ship, so that the ship can maintain balance and appropriate draft, thereby ensuring the stability and safety of the ship during navigation. It is usually stored in the ship's ballast tanks, which are distributed at the bottom and sides of the ship. The source of ballast water is very wide, including ports, waterways and other waters. However, ship ballast water also brings some environmental problems, because organisms in different waters may be brought to other places with ballast water. These alien organisms may become invasive species in the new environment, causing damage to the local ecosystem;

[0003] At present, in the prior art, when the ship driver is preparing to enter the port from the deep sea, the ballast water is usually replaced. During the ballast water replacement process, the ballast water is usually required to be filtered. For example, the Chinese patent with the announcement number "CN216890478U" discloses a ship ballast water disinfection treatment device. During the application of the device, when the ballast water needs to be discharged, the ballast water is first filtered by the filter tank and then enters the disinfection tank. The ultraviolet lamp disinfects the ballast water entering the disinfection tank. At the same time, the stirring element stirs the ballast water, and stirs the ballast water at the bottom of the disinfection tank to the upper side of the disinfection tank, which helps to prevent the ballast water on the ship from causing adverse effects on the receiving port waters when it is discharged into another water area, and protects the ecosystem of the water area;

[0004] Although the above-mentioned ship ballast water treatment device has a certain water treatment capacity, it still exposes several defects and shortcomings during actual operation. In the overall disinfection link, since the disinfection lamp is located at the top of the device, it is difficult for the ultraviolet light to evenly cover the ballast water at the bottom of the disinfection tank. Although the device is equipped with a stirring structure, the stirring structure only performs simple stirring through the stirring plate. Its design is relatively simple and cannot achieve efficient mixing of the ballast water. This causes the ultraviolet light emitted by the disinfection lamp to be unable to fully contact the ballast water, making it difficult to achieve efficient and uniform disinfection of the ballast water at the bottom of the tank. In summary, the existing device has obvious shortcomings and urgently needs to be optimized and improved in design to improve its treatment efficiency and disinfection effect and ensure the treatment quality of ship ballast water. Summary of the invention

[0017] A method for treating ship ballast water with ultraviolet light comprises the following steps:

[0018] Step 1: Connect the pipes. Connect the water inlet pipe to the external ballast water pipe through the connecting flange so that the ballast water can flow into the device;

[0019] Step 2: Preliminary filtration: the ballast water enters the filter tank through the water inlet pipe and is initially filtered by the filter screen. Large particles of impurities are intercepted on the outer surface of the filter screen.

[0020] Step 3: Start the drive motor. After the filtration is completed, start the drive motor. The motor drives the gear to rotate. Because the gear is meshed with the gear ring, the gear ring rotates synchronously. The rotation of the gear ring prompts the propeller to start working. At the same time, the rotation of one gear drives the linkage of multiple gears. The shaft at the bottom of the gear also rotates, and the stirring plate on the shaft starts to rotate.

The propeller also drives the ballast water to roll up and down to achieve efficient and uniform ultraviolet disinfection of the ballast water.

[0022] Step 5: Cleaning impurities. During the operation of the drive motor, the motor drives the gears to rotate. Through the meshing transmission of the gear ring, all gears rotate synchronously, driving the rotating shaft and the cleaning frame connected to the outside of the rotating shaft to rotate. The telescopic spring inside the cleaning frame pushes the slide plate to move, so that the brush bristles fit tightly against the outer surface of the filter screen. As the drive motor continues to run, the shaft drives the brush plate to rub and clean the top of the filter screen, and the scratching frame scratches the bottom of the filter tank. The filtered impurities slide along the conical surface of the conical filter screen to the bottom of the filter tank, and are then pushed to the inlet of the discharge pipe by the scratching frame, and finally enter the collection tank;

[0023] Step 6: Clean the waste residue. After using the equipment, open the threaded cover at the bottom and clean the waste residue in the collection tank.

[0024] In summary, the present invention mainly has the following beneficial effects:

[0025] First, this device can improve the ballast water treatment efficiency during use through the coordinated operation of the driving and disinfection mechanisms. During treatment, the water is first filtered through the filtering mechanism, and the driving motor is started after completion. The motor drives the gears. Because the gears are meshed with the gear rings, the gear rings rotate accordingly, driving the propeller to operate. At the same time, the rotation of one gear drives the other gears to rotate, so that the shaft at the bottom of the gear rotates, thereby driving the stirring plate to rotate. The stirring plate stirs the ballast water between the second ultraviolet lamp and the propeller stirs the ballast water between the first ultraviolet lamp and the second ultraviolet lamp. They are in the gap between the two lamps and can stir efficiently, thereby improving the contact effect between ultraviolet rays and ballast water, allowing ultraviolet rays to evenly cover the ballast water in various parts of the treatment tank. The propeller can also drive the ballast water to roll up and down to avoid dead corners of disinfection, and achieve efficient and uniform ultraviolet disinfection;

[0026] Second, by setting up a filtering mechanism, it can be started by starting the drive motor during use, driving the gears to rotate, and all the gears to rotate synchronously through the gear ring transmission, driving the rotating shaft and the cleaning frame to rotate. When in use, the water inlet pipe is connected to the external pipe through the connecting flange, and the ballast water flows into the filter tank and is filtered by the filter mesh cover. Large particles of impurities are intercepted outside the mesh cover. The motor drives the cleaning frame, and its internal telescopic spring pushes the slide plate to make the brush plate bristles fit the surface of the mesh cover. The rotating shaft drives the brush plate to clean the top of the mesh cover, and the scratch frame cleans the bottom of the tank. Because the mesh cover is conical, impurities slide along the conical surface to the bottom of the tank, and are pushed to the discharge pipe by the scratch frame and enter the collection tank. After use, open the bottom threaded cover to clean the waste residue, realize automatic cleaning, and facilitate the use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The disinfection mechanism 6 includes a stirring assembly 61 and a fixed plate 62. The fixed plate 62 is fixedly installed in the middle of the bottom of the top cover 2. The bottom of the fixed plate 62 is evenly spaced and arranged in a ring shape with first ultraviolet lamps 63 installed at equal intervals. The stirring assembly 61 is fixedly installed at the bottom of the driving mechanism 5. The stirring assembly 61 is arranged on the outside of the first ultraviolet lamp 63. When treating ballast water, the water is first filtered by the filtering mechanism 7. After the filtration is completed, the driving motor 51 is started, and the motor drives the gear 52 to rotate. Since the gear 52 is engaged with the gear ring 53, the gear ring 53 rotates accordingly, thereby driving the propeller 613 to work. At the same time, the gear 52 is linked to rotate the shaft 611 to drive the stirring plate 612 to rotate. The stirring plate 612 and the propeller 613 stir the ballast water between the second ultraviolet lamp 64, the first ultraviolet lamp 63 and the second ultraviolet lamp 64 respectively. The two work efficiently in the gap between the lamps, so that the ultraviolet rays evenly cover the ballast water everywhere, avoid disinfecting corners in disinfection, and achieve efficient and uniform ultraviolet disinfection effect.

[0039] refer to Figure 1-Figure 6The disinfection mechanism 6 also includes a base plate 65, which is arranged in a ring shape at equal intervals and fixedly connected to the bottom of the top cover 2 and located on the outside of each first ultraviolet lamp 63. A second ultraviolet lamp 64 is fixedly installed at the bottom of the base plate 65, and the second ultraviolet lamp 64 is arranged in the gap of the stirring component 61. The base plate 65 is arranged in a ring shape at equal intervals at the bottom of the top cover 2 and on the outside of each first ultraviolet lamp 63, and the second ultraviolet lamp 64 installed at its bottom is located at the gap of the stirring component 61, and cooperates more closely with the stirring component 61. When the stirring plate 612 and the propeller 613 stir the ballast water between the first ultraviolet lamp 63 and the second ultraviolet lamp 64, the second ultraviolet lamp 64 can irradiate the water from more angles, greatly increasing the coverage of ultraviolet rays. Under the efficient stirring of the stirring component 61, the first ultraviolet lamp 63 and the second ultraviolet lamp 64 evenly irradiate the ballast water in an all-round and dead angle manner, further ensuring that there will be no dead angle for disinfection, thereby more efficiently and thoroughly realizing the ultraviolet disinfection of the ballast water, and ensuring the treatment quality of the ballast water.

[0040] refer to Figure 4-Figure 6The driving mechanism 5 includes a driving motor 51, a gear 52 and a gear ring 53. The gear ring 53 and the gear 52 are meshed and connected. The driving motor 51 is fixedly installed on the top of the top cover 2 on one side away from the disinfection mechanism 6. The gears 52 are arranged in a ring shape at equal intervals and are opened at the bottom of the top cover 2. The gear ring 53 is rotatably connected to the outer side of the base plate 65. The output end of the driving motor 51 passes through the top cover 2 and is fixedly connected to the top of a gear 52. The stirring assembly 61 is installed at the bottom of the gear 52 and the gear ring 53. The stirring assembly 61 includes a shaft 611. The shaft 611 is fixedly installed at the bottom of the gear 52. The outer surface of the shaft 611 is fixedly installed with stirring plates 612 at equal intervals.

The stirring assembly 61 also includes a propeller 613. The propeller 613 is fixedly connected to the bottom of the gear ring 53 at equal intervals. The propeller 613 is arranged on the inner side of the first ultraviolet lamp 63 and the second ultraviolet lamp 64 The bottom of the propeller 613 is conically arranged and extends into the conical discharge bucket 8. The driving motor 51 is installed on one side of the top of the top cover 2, and its output end is connected to the gear 52. Through the meshing of the gear 52 and the gear ring 53, efficient power transmission is achieved. The gear ring 53 is rotatably connected to the outside of the base plate 65 to drive the entire stirring assembly 61 to operate. The shaft 611 is fixed at the bottom of the gear 52. The stirring plate 612 on the outer surface is staggered with the second ultraviolet lamp 64, which can effectively disturb the water flow during operation, allowing the second ultraviolet lamp 64 to give full play to the advantage of multi-angle irradiation. The propeller 613 is equidistantly connected to the bottom of the gear ring 53, located between the first ultraviolet lamp 63 and the second ultraviolet lamp 64, and its bottom conical design extends into the discharge bucket 8. It can not only make the ballast water roll up and down during the stirring process, but also receive ultraviolet irradiation in all directions to avoid disinfecting corners of disinfection and achieve efficient and thorough ultraviolet disinfection. It can also assist in drainage after the treatment is completed, optimize the entire treatment process, and greatly improve the practicality and treatment efficiency of the device.

[0041] refer to Figure 3-Figure 8The filter mechanism 7 includes a filter tank 71, a drainage bucket 72 is fixedly installed at the bottom of the filter tank 71, and the drainage bucket 72 is fixedly installed on the top of the top cover 2 away from the driving motor 51. A filter assembly 73 is movably installed inside the filter tank 71. The bottom of the filter assembly 73 passes through the top cover 2 and is connected to a gear 52. A water inlet pipe 74 is fixedly installed on the top of the filter tank 71, and a connecting flange 75 is fixedly installed on the input end of the water inlet pipe 74. The filter assembly 73 includes a filter screen cover 731, which is set in a conical shape. The filter screen cover 731 is fixedly installed at the bottom of the filter tank 71, and the middle part of the filter screen cover 731 is rotatably connected with a rotating shaft 732 The bottom of the rotating shaft 732 passes through the filter screen cover 731 and is fixedly connected to the top of a gear 52. A cleaning frame 733 is fixedly connected to the top outer surface of the rotating shaft 732 at equal intervals. Telescopic springs 734 are fixedly connected to the inside of the cleaning frame 733 at equal intervals. A slide plate 735 is slidably connected to the inside of the cleaning frame 733. The outer side of the slide plate 735 is fixedly connected to the end of the telescopic spring 734. A brush plate 736 is fixedly installed at the bottom of the slide plate 735. The bottom of the brush plate 736 is fitted and connected to the outer surface of the filter screen cover 731. A scratch frame 737 is fixedly connected to the outer side of the brush plate 736. The outer side of the scratch frame 737 is fitted and connected to the bottom of the filter tank 71. The filter tank A discharge pipe 76 is fixedly installed at the lower end of the outer side of 71, and the input end of the discharge pipe 76 is arranged on one side of the upper end of the filter screen cover 731 in the filter tank 71. A collection tank 77 is fixedly installed at the output end of the discharge pipe 76. A threaded cover 78 is threadedly connected to the bottom output end of the collection tank 77. Through the connection flange 75 and the water inlet pipe 74, it can be conveniently connected to the external ballast water pipeline, so that the ballast water flows into the conical filter screen cover 731. The unique conical design is conducive to the sliding of impurities. The rotating shaft 732 rotatably connected in the middle of the filter screen cover 731 is connected to the gear 52, and can be operated with the help of the power of the driving mechanism 5. When the gear 52 rotates to drive the rotating shaft 732, the cleaning frame on the top thereof 733 rotates accordingly, and the telescopic spring 734 in the cleaning frame 733 pushes the slide plate 735, so that the brush plate 736 fits tightly against the outer surface of the filter screen cover 731 to efficiently clean the filter screen. At the same time, the scratching frame 737 on the outside of the brush plate 736 scratches the bottom of the filter tank 71, and guides the filtered impurities to the discharge pipe 76 and discharges them into the collection tank 77. After the treatment is completed, unscrew the threaded cover 78 at the bottom of the collection tank 77 to easily clean the waste residue. The entire filtering mechanism 7 not only realizes efficient filtration of ballast water, but also cleverly uses the power of the driving mechanism 5 to complete automatic cleaning, which greatly improves the overall operating efficiency and convenience of the device and ensures the smoothness and environmental protection of the treatment process.

[0042] A method for treating ship ballast water with ultraviolet light comprises the following steps:

[0043] Step 1: Connect the pipes, connect the water inlet pipe 74 to the external ballast water pipe through the connecting flange 75, so that the ballast water can flow into the device;

[0044] Step 2: Preliminary filtration: the ballast water enters the filter tank 71 through the water inlet pipe 74 and is preliminarily filtered by the filter screen 731. Large particles of impurities are intercepted on the outer surface of the filter screen 731.

[0045] Step 3: Start the driving motor 51. After the filtration is completed, start the driving motor 51. The motor operation drives the gear 52 to rotate. Since the gear 52 is meshed with the gear ring 53, the gear ring 53 rotates synchronously. The rotation of the gear ring 53 causes the propeller 613 to start working. At the same time, the rotation of one gear 52 drives the other multiple gears 52 to work in conjunction. The shaft 611 at the bottom of the gear 52 also rotates, and the stirring plate 612 on the shaft 611 starts to rotate.

[0046] Step 4: stirring and disinfection. The stirring plate 612 stirs between the second ultraviolet lamp 64, and the propeller 613 stirs the ballast water between the first ultraviolet lamp 63 and the second ultraviolet lamp 64 to ensure that the ballast water flows stably between the two lamps. The propeller 613 and the stirring plate 612 stir efficiently between the two lamps so that the ultraviolet light evenly covers the ballast water at various positions in the treatment tank 1. The propeller 613 also drives the ballast water to roll up and down, thereby achieving efficient and uniform ultraviolet disinfection of the ballast water.

[0047] Step 5: cleaning impurities. During the operation of the driving motor 51, the motor drives the gear 52 to rotate. Through the meshing transmission of the gear ring 53, all the gears 52 rotate synchronously, driving the rotating shaft 732 and the cleaning frame 733 connected to the outside of the rotating shaft 732 to rotate. The telescopic spring 734 inside the cleaning frame 733 pushes the slide plate 735 to move, so that the bristles of the brush plate 736 are closely attached to the outer surface of the filter screen cover 731. As the driving motor 51 continues to operate, the rotating shaft 732 drives the brush plate 736 to rub and clean the top of the filter screen cover 731, and the rubbing frame 737 rubs the bottom of the filter tank 71. The filtered impurities slide along the conical surface of the conical filter screen cover 731 to the bottom of the filter tank 71, and are then pushed to the entrance of the discharge pipe 76 by the rubbing frame 737, and finally enter the collection tank 77.

[0048] Step 6: Cleaning up the waste residue. After the equipment is used up, open the threaded cover 78 at the bottom and clean up the waste residue in the collection tank 77.

[0049] Principle and advantages of use: By designing the coordinated operation of the driving mechanism 5 and the disinfection mechanism 6, the efficiency of the device in treating ballast water can be significantly improved during use. In the process of ballast water treatment, the filtering mechanism 7 first performs preliminary filtration on the water. After the filtration is completed, the driving motor 51 is started. The operation of the motor drives the gear 52 to rotate. Since the gear 52 is meshed with the gear ring 53, the gear ring 53 is driven to rotate synchronously. The rotation of the gear ring 53 prompts the propeller 613 to start working. At the same time, the rotation of one gear 52 can drive the linkage of multiple other gears 52, thereby causing the shaft 611 at the bottom of the gear 52 to rotate accordingly, and the stirring plates 612 evenly distributed on the shaft 611 also start to rotate. 612 stirs the ballast water between the first and second ultraviolet lamps 64, while the propeller 613 stirs the ballast water between the first and second ultraviolet lamps 63, 64, to ensure that the ballast water flows stably between the two lamps. Since the propeller 613 and the stirring plate 612 are both located in the gap between the first and second ultraviolet lamps 63, 64, they can stir more efficiently, greatly improving the contact effect between the ultraviolet lamps and the ballast water, so that the ultraviolet rays can evenly cover the ballast water at various positions in the treatment tank 1. In addition, the propeller 613 can drive the ballast water to roll up and down, further enhancing the overall stirring effect, effectively avoiding dead corners during the ultraviolet disinfection process, and achieving efficient and uniform ultraviolet disinfection of the ballast water.

[0050] By setting the filtering mechanism 7, when the driving motor 51 is running, the motor drives the gear 52 to rotate, and through the meshing transmission of the gear ring 53, all the gears 52 rotate synchronously, and the rotation of the gear 52 drives the rotating shaft 732 to rotate, and then the cleaning frame 733 connected to the outside of the rotating shaft 732 rotates accordingly. In actual use, the water inlet pipe 74 is connected to the external ballast water pipeline through the connecting flange 75, and the ballast water enters the filter tank 71 through the water inlet pipe 74, and is filtered by the filter screen cover 731, and large particles of impurities are intercepted on the outer surface of the filter screen cover 731. At the same time, the driving motor 51 drives the gear 52 to rotate, and then drives the rotating shaft 732 and the cleaning frame 733 to rotate. The telescopic spring 734 inside the cleaning frame 733 pushes the slide plate 735 to move, so that the brush plate 7 The bristles of the brush 36 fit tightly to the outer surface of the filter screen cover 731. As the drive motor 51 continues to operate, the rotating shaft 732 drives the brush plate 736 to brush and clean the top of the filter screen cover 731, and the scratching frame 737 scratches the bottom of the filter tank 71. Since the filter screen cover 731 is conical, the filtered impurities can slide along the conical surface to the bottom of the filter tank 71, and then be pushed to the entrance of the discharge pipe 76 by the scratching frame 737, and finally enter the collection tank 77. After the equipment is used, it is only necessary to open the threaded cover 78 at the bottom to easily clean the waste residue in the collection tank 77. It can be seen that the filter mechanism 7 of the present equipment cleverly uses the power of the drive mechanism 5 to achieve automatic cleaning, which provides great convenience for the filtration, purification and disinfection of ballast water, and greatly enhances the practicality of the device.
