Description

Technical Field

[0002] During the operation of ships, the treatment of ship ballast water quality is extremely important. In order to comply with international conventions and environmental protection requirements, a series of treatments are required for ship ballast water to remove or kill harmful organisms and pathogens that may be carried in it, prevent ecological damage and biological invasion between different sea areas, and remove impurities such as suspended solids and oil to improve water quality. Common treatment methods include filtration, sterilization and disinfection, separation, and the use of monitoring and control modules to ensure that the treated ballast water meets the standards for discharge or reuse, thereby ensuring the safe operation of ships and the balance of marine ecology;

[0003] The Chinese patent with the announcement number "CN220412964U" discloses a ship ballast water LED lamp ultraviolet disinfection treatment device, which uses an anti-reflection outer shell, an inner shell, a current adjustment member, a light-transmitting sleeve and an LED lamp group, and uses an LED ultraviolet lamp for disinfection, which overcomes the fragility and environmental pollution problems of traditional ultraviolet lamps, controls the floor space, and reduces hydraulic loss and energy consumption;

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] First, in the present invention, by setting up a filtering mechanism, the ballast water treatment process is optimized. When in use, the outer connecting flange of the connecting pipe is connected to the ballast water pipeline, and the ballast water is transported through the connecting pipe and the delivery pipe. The flow rate is controlled by means of a flow regulating valve to prevent water from overflowing the annular water retaining enclosure. The filter screen cover and the filter screen cylinder of the filtering mechanism filter the ballast water, and at the same time, the ultraviolet sterilization lamp is started to irradiate and sterilize the inside of the treatment tank. During the sterilization process, the driving motor drives the gear to rotate, so that the gear ring rotates, and then drives the filter screen cover and the filter screen cylinder at the bottom thereof to rotate on the top of the treatment tank, effectively avoiding the filtered impurities from covering the outer surface of the filter screen cylinder, improving the filtering efficiency, preventing clogging, and improving the ballast water treatment efficiency.

Since the transmission directions of the gear and the gear ring are opposite, and the gear drives the synchronous wheel to drive in the same direction, the stirring component and the filtering component rotate in the opposite direction, which assists in extruding and discharging the filtered material and achieves a good cleaning effect. In addition, the rotation of the rotating shaft drives the scraping frame to clean the inner wall of the filter screen cover and transmit impurities downward;

[0020] Thirdly, in the present invention, during the treatment process, the filter screen cover is adjusted to rotate by the driving component to drive the bottom spiral stirring blade, the connecting arm and the stirring plate to rotate, so as to stir the water in the treatment tank body, promote the efficient flow of the water, and cooperate with the ultraviolet sterilization lamp to quickly and evenly sterilize; when disinfectant solution is needed, stirring can make the solution and the water evenly mixed, thereby improving the sterilization effect. When draining water, the first regulating valve is closed and the second regulating valve is opened. After draining, the first regulating valve is opened, and the first auger and the second auger drive impurities to be discharged from the first discharge valve. After treating the ballast water, the device can automatically clean the filter screen cover and the filter screen cylinder. The impurities can be discharged by opening the first solenoid valve, thereby improving the cleaning effect, allowing the device to be quickly put into use, and further improving the overall ballast water treatment efficiency.

[0037] A flow-controllable ship ballast water quality treatment system comprises a filtering module, a sterilization and disinfection module, a separation module, a monitoring and control module, and a ballast pump pipeline module.

When the flow-controllable ship ballast water quality treatment system is working, the ballast water is first transported to the filtering module through the ballast pump pipeline module, the filtering module removes impurities such as suspended particles in the water, preliminarily purifies the water quality, and then, The treated water flows to the sterilization and disinfection module through the ballast pump pipeline module. This module uses chemical or physical methods to kill harmful organisms and pathogens in the water to ensure water quality safety. Then, the sterilized and disinfected water enters the separation module with the help of the ballast pump pipeline module to further separate the residual oil and water and solid-liquid components to improve the water purity. During the entire treatment process, the monitoring and control module monitors the key parameters of each module in real time, and is electrically connected to the filtration module, sterilization and disinfection module, separation module and ballast pump pipeline module. The operating status of each module is adjusted in time according to the monitoring data to ensure stable and efficient operation of the system and realize comprehensive and accurate treatment of ship ballast water.

[0038] The working principle of the present invention is as follows: by setting the filtering mechanism 6, when the device is put into use, the connecting flange 626 on the outer side of the connecting pipe 625 can be used to connect to the ballast water pipeline, and then the ballast water can be transported through the connecting pipe 625 and the delivery pipe 623. In this process, the flow regulating valve 624 can be used to adjust the delivery flow of the ballast water to prevent the ballast water from overflowing the annular water retaining enclosure 621. In the filtration link of the ballast water, the filter screen cover 61 and the filter screen cylinder 66 of the filtering mechanism 6 are used to filter the ballast water. At the same time, the ultraviolet disinfection lamp 5 is started to irradiate the inside of the treatment tank body 4 to achieve a better sterilization effect. In the sterilization process, the driving motor is started, the driving gear 633 rotates, and then the gear ring 631 is driven to rotate, so that the filter screen cover 61 rotates at the top of the treatment tank body 4. With the rotation of the filter screen cover 61 and the filter screen cylinder 66 at the bottom thereof, it can prevent the filtered impurities from covering the outer surface of the filter screen cylinder 66, effectively improve the overall filtering efficiency, prevent the occurrence of clogging, and thus improve the ballast water treatment efficiency;

[0039] By setting the driving mechanism and the transmission group 634 to cooperate with each other, when in use, the driving motor is started to drive the gear 633 to rotate, the rotation of the gear 633 drives the gear ring 631 to rotate, the rotation of the gear ring 631 drives the top connecting shaft 6341 to rotate, the rotation of the connecting shaft 6341 drives the top synchronous wheel 6343 to rotate, when the synchronous wheel 6343 rotates, it drives the synchronous wheel 6343 on the top of the supporting frame 6342 to rotate through the synchronous belt transmission, and then drives the bottom rotating shaft 641 to rotate, when the rotating shaft 641 rotates, it synchronously drives the first auger 642 and the second auger 643 to rotate, the first auger 642 and the second auger 643 rotate between the filter screen cover 61 and the filter screen cover 61. The filter cylinder 66 rotates internally to scrape and clean its interior. It is worth noting that during the cleaning process, the transmission directions of the gear 633 and the gear ring 631 are opposite, causing the filter screen cover 61 to rotate in the forward direction, and the gear 633 drives the two synchronous wheels 6343 to transmit in the same direction, driving the connecting shaft 6341 at the bottom to drive the first auger 642 and the second auger 643 to rotate in the opposite direction. In this way, the rotation directions of the stirring component and the filter component are opposite, which helps to squeeze and discharge the filtered substances, so as to achieve a better cleaning effect. At the same time, the rotation of the driving shaft 641 will also drive the scratch frame 68 on its outer surface to rotate, and the scratch frame 68 rotates in contact with the inner wall of the filter screen cover 61 to scratch the filter screen. The inner wall of the cover 61 is scratched and cleaned, and the impurities filtered out from the inside of the filter cylinder 66 are assisted to be transmitted downward to prevent the filter cover 61 and the filter cylinder 66 from being blocked. During the treatment process, the rotation of the filter cover 61 will drive the spiral stirring blade 651 at the bottom to rotate. While the spiral stirring blade 651 rotates, it drives the connecting arm 652 and the stirring plate 653 at the bottom to rotate and stir, thereby stirring the water in the treatment tank body 4 and promoting the efficient flow of the water in the treatment tank body 4. This stirring function cooperates with the ultraviolet sterilization lamp 5 to help quickly and evenly sterilize. When disinfectant solution is needed for disinfection, the disinfectant solution can be evenly mixed with the water in the treatment tank body 4 to improve the disinfection efficiency. When draining water, close the first regulating valve 7 and open the second regulating valve 8 to drain water; after draining water, open the first regulating valve 7, and drive the impurities in the filter screen cover 61 and the filter screen cylinder 66 to move downward through the first auger 642 and the second auger 643, so that the filtered impurities can be better discharged from the first discharge valve. It can be seen that after completing the ballast water treatment, the device can automatically scrape and remove the impurities inside the filter screen cover 61 and the filter screen cylinder 66. Only the first solenoid valve needs to be opened to discharge the filtered impurities, thereby improving the cleaning effect of the device during use, allowing the device to be quickly put into use, and further enhancing the overall ballast water treatment efficiency of the equipment.
