Description

Technical Field

[0001] The invention relates to the technical field of ballast water treatment, in particular to an ultraviolet sterilization device for ballast water treatment. Background Art

[0002] The ultraviolet disinfection device for ballast water treatment is an important equipment specially used for treating ship ballast water. During the voyage, ships will inhale and discharge ballast water in order to maintain balance and stability. However, these ballast waters may carry various organisms, such as bacteria, viruses, algae, plankton, etc. If they are discharged directly without treatment, they may cause serious biological invasion and ecological damage to the local marine ecosystem. The ultraviolet disinfection device kills microorganisms in ballast water by emitting ultraviolet rays of a specific wavelength. Its working principle is to use ultraviolet rays to destroy the DNA and RNA of microorganisms, prevent their growth and reproduction, and thus achieve the purpose of sterilization and disinfection;

[0003] The Chinese patent with the announcement number "CN114716082A" discloses a low-energy consumption and fast-sterilizing ship ballast water treatment equipment, which includes a treatment device body, an ultraviolet lamp is fixedly connected to the inner side wall of the treatment device body, a support leg is fixedly connected to the bottom of the treatment device body, and a protective cover is movably connected to the inner wall of the treatment device body, a first fixed block is fixedly connected to one side of the protective cover, a second fixed block is fixedly connected to one side of the treatment device body, and a first fixing bolt is threadedly connected to the inside of the first fixing block through the second fixing block; the effect of filtering the ballast water is achieved by the mutual cooperation and connection of the fixing column, the filter barrel, the filter plate, the filter net, the connecting plate and the second fixing bolt, and the filter net and the filter plate inside the filter barrel are used to deeply filter the water, so as to avoid the blockage of the device caused by the mud in the water as much as possible;

[0004] During the application of the above-mentioned device, although the filter can be used for auxiliary filtering and screening to avoid the occurrence of clogging problems, the algae, plankton and impurities in the water filtered out by the filter will adhere to the outer surface of the filter. When the filter needs to be cleaned, it must be removed before proceeding. During the entire operation, the equipment needs to be stopped first, and then tedious dismantling steps need to be performed. The entire cleaning process is extremely cumbersome and inconvenient, and the operation is quite complicated.

The ozone quickly reacts with the microorganisms in the water to further enhance the disinfection ability, and synergizes with the ultraviolet lamp 633 to significantly improve the overall disinfection and sterilization effect, providing reliable disinfection guarantee for the treatment of ballast water.

[0036] The working principle of the present invention is as follows: by setting up the filtering mechanism 5, during the use of the device, ballast water can be added to the interior of the filter bucket 51 through the water inlet pipe 558, the transfer water cylinder and the drain pipe 5510. When the water flows to the filtering inclined plate 53, the filtering inclined plate 53 can be used to assist in filtering the water. At this time, the solid impurities in the water can be filtered out by the filtering inclined plate 53. Since the filtering inclined plate 53 is inclined, it can guide the solid dust impurities by its own inclined surface, so that the dust impurities enter the receiving box 543 in the collection frame 541 through the guide plate 542. When cleaning is required, When cleaning, it is only necessary to loosen the hand-tightened screw 7 and remove the receiving box 543 inside the collecting frame 541. At the same time, during the filtering and screening process, when water flows into the transfer water cylinder, the water flow can be used to push the water flow push plate 556 to drive the rotating shaft 555 to rotate. The rotation of the rotating shaft 555 then drives the half gear 557 to rotate. When the half gear 557 rotates, it can drive the rack 553 and the sliding frame 552 on its outer side to slide inside the external frame 551. Since half of the half gear 557 has teeth and the other half has no teeth, when the half gear 557 is engaged with the top rack 553 to drive the sliding frame 552 to one side, the bottom of the half gear 557 The teeth at the top are meshed with the rack 553 at the bottom, and the half gear 557 is transformed into meshing with the rack 553 at the bottom. At this time, the sliding direction of the slide frame 552 can be changed, causing the slide frame 552 to slide toward the other side. The intermittent meshing transmission mode of the half gear 557 and the two racks 553 is adopted, so as to drive the slide frame 552 to slide back and forth inside the external frame 551. At this time, the brush plate 559 can be driven to slide back and forth on the top of the filter inclined plate 53. In the process of reciprocating sliding displacement, the brush plate 559 can brush the dust, thereby cleaning the stubborn impurities attached to the filter inclined plate 53. It can be seen that the device can realize the function of automatically discharging impurities and cleaning the filter inclined plate 53 by using the inclined filter inclined plate 53 and the water flow to drive the brush plate 559 to reciprocate. During the overall application, solid impurities can be prevented from clogging the filter inclined plate 53, so that the device does not need to frequently remove the filter inclined plate 53 and can be repeatedly put into use continuously and uninterruptedly. Moreover, even if it needs to be removed for cleaning, it only needs to pull the bridge handrail 8 to drive the limiting base plate 511 to pull the filter inclined plate 53 out from the inside of the built-in movable frame 52, which is convenient for replacing the filter inclined plate 53 and can improve the overall convenience of use of the device.

[0037] By setting the disinfection mechanism 6 and the purification mechanism 3 to cooperate with each other, after the device filters out impurities through the filtering inclined plate 53, the water flow can be assisted by the guide bucket 310 to guide the water liquid to the purification frame 37 inside the purification box 31. At this time, the water liquid can be purified by the activated carbon purification core 39 inside the purification frame 37, which can remove harmful substances in the water to the greatest extent. After the water liquid is purified, the water pump 32 is started to run, and the water liquid inside the purification box 31 can be transported to the inside of the disinfection tank 61 through the hose. At this time, the ultraviolet lamp 633 is started to disinfect and sterilize the inside of the disinfection tank 61. Since the interior of the disinfection tank 61 is circular and the ultraviolet lamps 633 are arranged at equal intervals, each ultraviolet lamp 633 can be evenly radiated to each corner of the disinfection tank 61, so that the overall disinfection of the device has no dead angles, which can improve its overall disinfection and sterilization effect. In addition, during the disinfection process, the ultraviolet lamp 633 can be started. When the ozone generator 634 is running, the ozone generated by the ozone generator 634 can quickly react with microorganisms such as bacteria, viruses, fungi in the water, destroy their cell structure and genetic material, so as to achieve the purpose of disinfection. After the water treatment is completed, it is only necessary to open the solenoid valve to discharge the disinfected water. At the same time, when the equipment needs to be inspected and maintained, it is only necessary to loosen the hand-tightening screw 7 to pull the sealing machine door 36, so that the slide plate 35 slides inside the slide rail 34, and the purification frame 37 installed on the inner side of the slide plate 35 is removed, so that the device can easily remove and replace the purification frame 37 and the activated carbon purification core 39 inside it. At the same time, by removing the hand-tightening screw 7 on the top of the disinfection tank 61, the sealing cover 631 and the ultraviolet lamp 633 at the bottom thereof can be removed from the inside of the disinfection tank 61, so that the device has a strong disinfection function as a whole, and the subsequent inspection and maintenance are more convenient, and the overall use is more convenient.
