Description

Technical Field

[0001] The invention relates to the field of ship equipment, and in particular to ship ballast water purification treatment equipment and system for automatically detecting sewage. Background Art

[0002] Ship ballast water refers to the water and suspended matter added to the ship to control the ship's heel, trim, draft, stability or stress, also known as ballast water. This water can be fresh water, seawater or suspended matter outside the ship. It is mainly used to maintain a certain depth of draft when the ship is unloaded to prevent capsizing, and to adjust the draft difference when the ship is loaded, to ensure the smooth and safe navigation of the ship in a specific water area. Ship ballast water contains a large number of organisms, including plankton, microorganisms, bacteria and even small fish and eggs, larvae or spores of various species. Some of these organisms die in the process of following the ship's voyage because they cannot adapt to the new environment, while others survive and are discharged into the new geographical environment with the ballast water, which may lead to the invasion of foreign marine organisms and damage the local ecosystem. Therefore, it is necessary to treat the ship's ballast water to achieve the purpose of environmental protection.

[0003] After searching, a Chinese patent with announcement number CN220335013U discloses ship ballast water treatment equipment, including: a primary sinking mechanism and a filtering and disinfecting mechanism, characterized in that a water storage tank is arranged on the primary sinking mechanism, and a water injection port, an inclined sieve plate, a mixing device, and a partition plate are arranged in sequence from top to bottom in the water storage tank, the mixing device is rotatably connected to the water storage tank, the bottom of the mixing device is connected to a driving motor, the driving motor is arranged on the lower side of the water storage tank, and a material storage mechanism and a drug injection port are arranged on the axial outer side of the water storage tank; a purification box, an activated carbon adsorption tower, and a disinfection box are connected to the filtering and disinfecting mechanism in sequence, the upper end of the purification box is connected to the bottom of the water storage tank through a drain pipe, and the bottom of the disinfection box is connected with a discharge port.

[0004] The ship ballast water treatment equipment in the above-mentioned prior art is used by adding a flocculant into the water storage tank and stirring it to form a separated precipitate, and then extracting the supernatant through a drain pipe at a fixed position for further purification. First, the position of the drain pipe is fixed, while the position of the supernatant is not fixed. When the position of the supernatant is lower than the discharge page of the drain pipe, the ballast water at the lower end of the drainage page of the drain pipe cannot be purified. When the flocculant separation impurities are flush with or higher than the drainage page of the drain pipe, the drain pipe will easily transport the ballast water with a large amount of dirt to the subsequent purification box, which will undoubtedly accelerate the reduction of the service life of the filter element. Secondly, in the subsequent purification process, when the purification box, activated carbon adsorption tower and ozone disinfection box are performing purification treatment, once an equipment failure occurs and the treatment is not perfect, the staff will not be able to perform maintenance in time, which will affect the ballast water treatment efficiency.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] First, in the present invention, the ballast water with flocculent separation can be conveniently discharged into the pretreatment tank through the guide pipe on the guide cover. At the same time, the ballast water is dispersedly discharged to the inclined filter screen through the guide pipe through the diverter for filtration. Therefore, it is no longer necessary to consider the height of the separation page between the supernatant and the flocculent dirt, and the treatment of the ballast water is greatly facilitated.

[0017] Secondly, in the present invention, the second driving motor is pneumatically driven, so that the output end of the second driving motor drives the second screw to rotate on the pretreatment box, so that the second moving rod threadedly connected to the outer side of the second screw slides, and the second moving rod drives the push shovel along the inclined surface of the inclined filter plate, and discharges the dirt filtered on the filter surface along the sewage discharge hole to the collection box for collection. At the same time, when the push shovel moves from the lower end of the inclined filter to the higher end, the output end of the micro electric push rod retracts and drives the push shovel to slide on the second moving rod, so that the lower end of the push shovel is no longer close to the inclined filter, until the inclined filter moves from the high position to the low position again, the output end of the electric push rod pushes the push shovel down again to get close to its filter surface for cleaning, thereby facilitating the cleaning of the inclined filter.

[0018] Thirdly, in the present invention, the first drive motor is started to run, so that the output end of the first drive motor drives the first screw to rotate in the pretreatment box, and at the same time, the first moving rod threadedly connected to the outer side of the first screw slides, and a flushing nozzle is installed at the bevel groove of the first moving rod, and the flushing nozzle is connected to the external joint through a hose, so that the first moving rod drives the flushing nozzle to move in an inclined state to reversely flush and dredge the inclined filter, thereby facilitating the reuse of the inclined filter;

[0019] Fourthly, in the present invention, one end of the collection box is inserted along the slot, and during the insertion process, the insertion end of the collection box presses the inclined surface of the card block extending from the slot, so that the movable plate connected to the card block slides on the guide rod in the installation slot, and the movable plate compresses the spring at the same time. When the collection box is inserted, and the card slot on one side of the collection box corresponds to the position of the card-inserted end of the card block, the spring in the installation slot elastically resets and pushes the movable plate to slide, and the card block on the movable plate is carded into the card slot. Conversely, when removing the collection box, it is only necessary to pull the movable plate by the hook part of the pull hook block to drive the movable plate to slide, so that the card block on the movable plate is separated from the card slot of the collection box, and the collection box can be pulled out of the slot at this time, so that the collection box can be quickly disassembled and used;

[0020] Fifth, in the present invention, by equipping two groups of purification devices on the mounting frame, if the equipment fails and the disinfection index does not meet the standard, the main control system first controls the delivery pump on the current purification device to run, and the delivery pump delivers the ballast water in the current purification device to another purification device on the mounting frame through the delivery pipeline at the output end for re-processing. After the water quality detection sensor detects that it meets the standard, the main control system controls the drain pipe battery valve of the other purification device to open, and discharges the purified ballast water. At the same time, the main control system will switch the battery valve at the three-way head connected to the pipeline of the current purification device to a closed state, and at the same time, the corresponding battery valve at the three-way head of another purification device is switched to an open state, thereby avoiding the problem of affecting the ballast water purification efficiency due to untimely maintenance.

After the water quality detection sensor 13 detects that it meets the standard, the main control system controls the drain pipe 12 battery valve of another purification device 8 to open to drain the purified ballast water. At the same time, the main control system will open the three-way head connected to the pipeline of the current purification device 8. The battery valve at the position is switched to the closed state, and the corresponding battery valve at the three-way head of another purification device 8 is switched to the open state, thereby avoiding the problem of affecting the ballast water purification efficiency due to untimely maintenance; in addition, after the current purification device 8 is maintained, the main control system activates the switching valve control unit and the switching pump control unit again, so that when the equipment fails again, the main control system can make timely adjustments. In the process of switching the purification device 8, the main control system triggers the sound and light alarm on the on-site electric control box, and at the same time, the early warning signal pops up on the control interface of the ship control room, so that the staff can understand the situation in time for machine maintenance. In the machine maintenance module part of the main control system, it will cooperate with the detection equipment and the power distribution system to determine whether the corresponding electrical or equipment has a fault and needs maintenance. ;

[0040] The working principle of the present invention is as follows: during use, the ballast water after flocculant separation is completely discharged into the pretreatment tank 2, and the ballast water enters the inclined filter screen 15 through the guide cover 5 for filtration. After filtration, the ballast water enters the pretreatment tank 2, and the impurities in the ballast water remain on the filter surface of the inclined filter screen 15. Then, the second drive motor 707 is pneumatically driven, so that the output end of the second drive motor 707 drives the second screw 702 to rotate on the pretreatment tank 2, so that the second moving rod 705 threadedly connected to the outer side of the second screw 702 slides, and the second moving rod 705 drives the push shovel 706 along the inclined surface of the inclined filter plate, and pushes the dirt filtered on the filter surface along the drainage hole 1 4 is discharged to the collection box 3 for collection. At the same time, when the push shovel 706 moves from the lower end to the higher end of the inclined filter screen 15, the output end of the micro electric push rod 703 retracts to drive the push shovel 706 to slide on the second moving rod 705, so that the lower end of the push shovel 706 is no longer close to the inclined filter screen 15, until the inclined filter screen 15 moves from the high position to the low position again, the output end of the electric push rod 703 pushes the push shovel 706 down again to be close to its filter surface for cleaning. By connecting the external connector 608 to the output end of the booster pump in the external boat room, the booster pump is connected to the clean water tank through the input end. When cleaning, the first drive motor 607 starts to run, so that the output end of the first drive motor 607 drives the first screw 602 rotates in the pretreatment box 2, and at the same time, the first moving rod 603 threadedly connected to the outer side of the first screw rod 602 slides, and the bevel groove 605 of the first moving rod 603 is installed with a flushing nozzle 604, and the flushing nozzle 604 is connected to the external joint 608 through a hose 606, so that the first moving rod 603 drives the flushing nozzle 604 to move in an inclined state to reversely flush and dredge the inclined filter 15. Subsequently, the output end of the water pump 9 transports the pretreated ballast water through the connecting pipe 11 to one of the purification devices 8 on the mounting frame 1 for purification treatment. After the purification is completed, the water quality is automatically detected by the water quality detection sensor 13 on the purification device 8. If When the equipment fails to meet the disinfection index, the main control system first controls the delivery pump on the current purification device 8 to run, and the delivery pump delivers the ballast water in the current purification device 8 to another purification device 8 on the mounting frame 1 through the delivery pipeline at the output end for further treatment. After the water quality detection sensor 13 detects that it meets the standard, the main control system controls the battery valve of the drain pipe 12 of another purification device 8 to open, and discharges the purified ballast water. At the same time, the main control system switches the battery valve at the three-way head of the pipeline of the current purification device 8 to a closed state, and at the same time, the corresponding battery valve at the three-way head of another purification device 8 is switched to an open state to ensure the ballast water treatment efficiency;

[0041] When installing the collecting box 3 on the pretreatment box 2, one end of the collecting box 3 is inserted along the slot 407. During the insertion process, the inserted end of the collecting box 3 squeezes the inclined surface of the block 403 extending from the slot 407, so that the movable plate 402 connected to the block 403 slides on the guide rod 404 in the mounting slot 401, and the movable plate 402 compresses the spring 405. When the collecting box 3 is inserted, and the slot 20 on one side of the collecting box 3 corresponds to the position of the snap-in end of the block 403, the spring 405 in the mounting slot 401 elastically resets and pushes the movable plate 402 to slide, and makes the block 403 on the movable plate 402 snap into the slot 20. Conversely, when removing the collecting box 3, it is only necessary to pull the movable plate 402 to slide by the hook block 406, so that the block 403 on the movable plate 402 is separated from the slot 20 of the collecting box 3, and then the collecting box 3 can be pulled out from the slot 407.
