Description

Technical Field

[0001] This invention relates to the field of ballast water treatment technology, and in particular to a composite ship ballast water treatment device and its treatment method. Background Technology

[0002] Ballast water refers to the water and suspended matter added to a ship to control its heel, trim, draft, stability, or stress. Ballast water contains a large amount of fixed debris, suspended particles, bacteria, and microorganisms. Untreated ballast water can cause biological invasion and endanger the safety of the water area and environment. Therefore, ballast water must be treated before being discharged.

[0003] Chinese Patent CN219635473U discloses a ship ballast water treatment device, including a treatment tank, a filter tank, a filter assembly, a stirring assembly, a disinfectant addition assembly, and a water guide valve. The filter tank is mounted on top of the treatment tank via a bracket. The filter assembly is located inside the filter tank. The stirring assembly is located inside the treatment tank. The disinfectant addition assembly is located on one side of the treatment tank. The water guide valve connects the treatment tank and the filter tank. The filter assembly includes a filter screen inclined plate, a sewage discharge chamber, a telescopic spring, a first filter plate, and a second filter plate. The filter screen inclined plate is slidably disposed inside the filter tank. The sewage discharge chamber is symmetrically disposed on both sides of the filter tank. A connecting groove is provided at the connection between the filter tank and the sewage discharge chamber.

[0004] However, in actual use, we have found that the ship ballast water treatment devices in the above-mentioned prior art still have some shortcomings. For example, if the first and second filter plates inside the treatment tank become clogged during the multi-stage filtration of ballast water, staff must go to the site immediately to maintain and treat them before drainage can continue. Therefore, this will affect the ballast water treatment efficiency to some extent. Summary of the Invention

[0015] A composite method for treating ship ballast water includes the following steps:

[0016] S1. When filtering ballast water, the ballast water is first introduced into the treatment tank through the inlet pipe. The water discharged into the treatment tank through the inlet pipe can filter out larger particles of impurities in the ballast water through the filter screen inclined plate in the filtration mechanism. At the same time, the impurities are collected in the collection box through the slag discharge hole along the inclined surface of the filter screen inclined plate under the action of vibration.

[0017] S2. Then, the ballast water after preliminary filtration is collected through the first water collection hopper in the treatment tank and discharged to the filter plate through the connecting pipe at the lower end of the first water collection hopper. Smaller impurity particles can be further filtered. After the filtered ballast water is collected through the second water collection hopper at the lower end, it is discharged through the second drain pipe at the lower end to the first drain pipe and then discharged to the next treatment stage.

[0018] S3. When the water flows through the second drain pipe below the corresponding filter plate, the flow velocity sensor in the second drain pipe can monitor the flow velocity of the ballast water discharged after filtration. When the corresponding filter plate is blocked and needs maintenance, the flow velocity of the water through the second drain pipe will also decrease, and then the flow velocity sensor will send a signal to the external control module.

[0019] S4. When the control module receives a signal from the flow rate sensor that reaches a certain set parameter index, the control module will control the operation of the conveying mechanism.

[0020] S5. When the conveying mechanism is running, the output end of the drive motor outside the treatment box drives the first screw to rotate inside the U-shaped frame, causing the moving rod connected to the thread on the outside of the first screw to slide. The moving rod moves from above the filter plate on one side of the partition in the treatment box to above the filter plate on the other side through the connecting pipe clamped by the external fixing mechanism. At this time, the ballast water can continue to be filtered through the unused filter plate.

[0021] S6. After the conveying mechanism transfers the connecting pipe to the corresponding filter plate, the control module outside the processing box will simultaneously issue an alarm signal and a signal indicator light, which can notify maintenance personnel to perform maintenance on the filter plate that needs maintenance.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] Firstly, in this invention, by installing a right-angle rod on the inside of the processing box, and the right-angle rod being connected to the filter screen inclined plate via a first spring, the impurities on the filter screen inclined plate can be collected along the inclined surface and through the slag discharge hole by the vibration motor at the lower end of the filter screen inclined plate under the vibration effect. The collection box is hung on the processing box, making it convenient to pour out the waste.

[0024] Secondly, in this invention, the lower end of the connecting pipe is inserted into the fixing hole of the fixing block, and then the second screw is rotated by the rotating block to extend and retract on the fixing block, so that the second screw rotates and pushes the clamping plate to slide. The clamping plate can clamp and fix the lower end of the connecting pipe through the clamping groove corresponding to the fixing hole. When adjusting the drainage position of the connecting pipe, the output end of the drive motor drives the second screw to rotate on the U-shaped frame inside the treatment box, so that the moving rod connected to the outer side of the second screw slides. At the same time, the front end of the moving rod can drive the connecting pipe through the fixing block to move from above the filter plate in one place of the treatment box to above the filter plate in another place. This makes it convenient to filter ballast water and avoid the situation where the staff cannot arrive on site in time to deal with the ballast water treatment, and the filtration efficiency of the ballast water is reduced due to blockage.

[0025] Thirdly, in this invention, the filter plate is inserted between the corresponding guide rails. During the insertion process, one side of the filter plate presses against the inserting end of the locking block extending from the inner side of the guide rail, causing the protrusion connected to the locking block to slide in the rectangular groove of the partition. At the same time, the protrusion compresses the second spring until the inserting end of the locking block corresponds to the slot on the outer side of the filter plate. Then, the second spring resets and pushes the locking block connected to the protrusion to lock and fix the filter plate in the guide rail. This can prevent the instability of the filter plate caused by the swaying of the hull. When disassembling, the protrusion of the protrusion is pushed towards the side of the second spring in the rectangular groove, which can separate the locking block on the protrusion from the slot of the filter plate, thus facilitating quick disassembly and maintenance of the filter plate.

The side of the clamping plate 184 away from the second screw 186 is rotatably connected to the opposite surface of the fixing hole 182. Each component is provided with a clamping groove 183. The fixing block 181 clamps the lower end of the connecting pipe 15 inside the fixing hole 182 via the clamping plate 184. When fixing the pipe head of the connecting pipe 15 at the lower end of the first water collecting hopper 14, the lower end of the connecting pipe 15 is inserted into the fixing hole 182 of the fixing block 181. Then, the second screw 186 is rotated by the rotating block 185 to extend and retract on the fixing block 181, causing the second screw 186 to rotate and push the clamping plate 184 to slide. The clamping plate 184, through the clamping groove 183 corresponding to the fixing hole 182, can... The lower end of the connecting pipe 15 is clamped and fixed. When adjusting the drainage position of the connecting pipe 15, the output end of the drive motor 162 drives the second screw 186 to rotate on the U-shaped frame 161 inside the treatment box 1, so that the moving rod 164 threaded on the outer side of the second screw 186 slides.

During insertion, the filter plate 19... The locking end of the locking block 241 extending from the inner side of the guide rail 20 is pressed, causing the protrusion 243 connected to the locking block 241 to slide in the rectangular groove 242 of the partition plate 21. At the same time, the protrusion 243 compresses the second spring 245 until the locking end of the locking block 241 corresponds to the position of the slot 26 on the outer side of the filter plate 19. Then, the second spring 245 resets and pushes the locking block 241 connected to the protrusion 243 to lock and fix the filter plate 19 in the guide rail 20. This can prevent the hull from shaking and causing instability of the filter plate 19. When disassembling, the protrusion of the protrusion 243 is pushed towards the side of the second spring 245 in the rectangular groove 242 to separate the locking block 241 on the protrusion 243 from the slot 26 of the filter plate 19, so that the filter plate 19 can be quickly disassembled and maintained.

The end of the protrusion 243 is slidably connected to the inner side of the second sliding groove 28. By sliding the protrusion 243 in the second sliding groove 28 of the rectangular groove 242, the stability of the protrusion 243 can be improved. The protrusion of the protrusion of the protrusion 243 extends out of the rectangular groove 242, which makes it convenient to operate and use the protrusion 243.

[0044] A composite method for treating ship ballast water includes the following steps:

[0045] S1. When filtering ballast water, the ballast water is first introduced into the treatment tank 1 through the inlet pipe 2. The water discharged into the treatment tank 1 through the inlet pipe 2 can filter out larger particles of impurities in the ballast water through the filter screen inclined plate 111 in the sieve mechanism 11. At the same time, the impurities are collected in the collection box 3 through the slag discharge hole 10 along the inclined surface of the filter screen inclined plate 111 under the action of vibration.

[0046] S2. Then, the ballast water after preliminary filtration is collected through the first water collection bucket 14 in the treatment tank 1 and discharged to the filter plate 19 through the connecting pipe 15 at the lower end of the first water collection bucket 14. Smaller impurity particles can be further filtered. The filtered ballast water is collected through the second water collection bucket 22 at the lower end and then discharged to the first drain pipe 4 through the second drain pipe 5 at the lower end and discharged to the next treatment stage.

[0047] S3. When the water flows through the second drain pipe 5 below the corresponding filter plate 19, the flow rate sensor 6 in the second drain pipe 5 can monitor the flow rate of the ballast water discharged after filtration. When the corresponding filter plate 19 is blocked and needs maintenance, the flow rate of the water through the second drain pipe 5 will also decrease, and then the flow rate sensor 6 will send a signal to the external control module 9.

[0048] S4. When the control module 9 receives a signal from the flow rate sensor 6 that reaches a certain set parameter index, the control module 9 will control the operation of the conveying mechanism 16.

[0049] S5. When the conveying mechanism 16 is running, the output end of the drive motor 162 outside the treatment box 1 drives the first screw 163 to rotate inside the U-shaped frame 161, causing the moving rod 164 threadedly connected to the outside of the first screw 163 to slide. The moving rod 164 moves from above the filter plate 19 on one side of the partition 21 in the treatment box 1 to above the filter plate 19 on the other side through the connecting pipe 15 clamped by the external fixing mechanism 18. At this time, the ballast water can continue to be filtered through the unused filter plate 19.

[0050] S6. After the conveying mechanism 16 transfers the connecting pipe 15 above the corresponding filter plate 19, at the same time, the control module 9 outside the processing box 1 will issue an alarm signal and a signal indicator light, which can notify the maintenance personnel to perform maintenance on the filter plate 19 that needs maintenance.

[0051] The working principle of this invention is as follows: During use, ballast water is first introduced into the treatment tank 1 through the inlet pipe 2. The water discharged into the treatment tank 1 through the inlet pipe 2 passes through the filter screen inclined plate 111 in the filtration mechanism 11, which can filter out larger particles of impurities in the ballast water. At the same time, under the action of vibration, the impurities enter the collection box 3 through the slag discharge hole 10 along the inclined surface of the filter screen inclined plate 111 for collection. Then, the ballast water after preliminary filtration is collected through the first water collection hopper 14 in the treatment tank 1 and discharged through the connecting pipe 15 at the lower end of the first water collection hopper 14 onto the filter plate 19, which can further filter smaller particles of impurities. The filtered ballast water is collected through the second water collection hopper 22 at the lower end and then discharged through the second drain pipe 5 at the lower end to the first drain pipe 4 and discharged to the next treatment stage. When the water flows through the second drain pipe 5 below the corresponding filter plate 19, the flow rate sensor in the second drain pipe 5... Device 6 can monitor the flow rate of the ballast water discharged after filtration. When the corresponding filter plate 19 is clogged and needs maintenance, the flow rate of water through the second drain pipe 5 will also decrease. Then, the flow rate sensor 6 sends a signal to the external control module 9. When the control module 9 receives the signal fed back by the flow rate sensor 6 and it reaches a certain set parameter index, the control module 9 will control the operation of the conveying mechanism 16. When the conveying mechanism 16 is running, the output end of the drive motor 162 outside the treatment box 1 drives the first screw 163 to rotate inside the U-shaped frame 161, so that the moving rod 164 threadedly connected to the outside of the first screw 163 slides. The moving rod 164 moves from above the filter plate 19 on one side of the partition 21 in the treatment box 1 to above the filter plate 19 on the other side through the connecting pipe 15 clamped by the external fixing mechanism 18. At this time, the ballast water can continue to be filtered through the unused filter plate 19.

[0052] When fixing the lower end of the connecting pipe 15 at the first water collection hopper 14, the lower end of the connecting pipe 15 is inserted into the fixing hole 182 of the fixing block 181. Then, the second screw 186 is rotated by the screw block 185 to extend and retract on the fixing block 181, so that the second screw 186 rotates and pushes the clamping plate 184 to slide. The clamping plate 184 can clamp and fix the lower end of the connecting pipe 15 through the clamping groove 183 corresponding to the fixing hole 182. When installing the filter plate 19, the filter plate 19 is inserted between the corresponding guide rails 20. During the insertion process, one side of the filter plate 19 presses against the insertion end of the locking block 241 extending from the inside of the guide rail 20, so that the locking block 241... The protrusion 243 connected to the partition 21 slides in the rectangular groove 242, while the protrusion 243 compresses the second spring 245 until the snap-in end of the locking block 241 corresponds to the position of the locking groove 26 on the outside of the filter plate 19. Then the second spring 245 resets and pushes the locking block 241 connected to the protrusion 243 to lock and fix the filter plate 19 in the guide rail 20. This can prevent the hull from shaking and causing instability of the filter plate 19. When disassembling, the protrusion of the protrusion 243 is pushed towards the side of the second spring 245 in the rectangular groove 242, so that the locking block 241 on the protrusion 243 can be separated from the locking groove 26 of the filter plate 19, and the filter plate 19 can be quickly disassembled and maintained.

When filtering ballast water, the ballast water is first introduced into the treatment tank (1) through the inlet pipe (2). The water discharged into the treatment tank (1) through the inlet pipe (2) can filter out larger particles of impurities in the ballast water through the filter screen inclined plate (111) in the sieve mechanism (11). At the same time, the impurities are collected in the collection box (3) through the slag discharge hole (10) along the inclined surface of the filter screen inclined plate (111) under the action of vibration. S2. Then the ballast water after preliminary filtration is collected through the first water collection bucket (14) in the treatment tank (1) and discharged to the filter plate (19) through the connecting pipe (15) at the lower end of the first water collection bucket (14). Smaller impurity particles can be further filtered.
