A flow-controllable ship ballast water quality treatment device and system

Abstract

This invention relates to the field of ballast water treatment technology, specifically disclosing a controllable flow rate treatment device and system for ship ballast water. The device includes a base with support legs fixedly installed in a ring at equal intervals on its top. The invention utilizes a drive mechanism and transmission components to activate a drive motor. Through a series of transmissions, the first and second augers rotate within the filter screen and cylinder. Due to the characteristics of gear, gear ring, and synchronous wheel transmissions, the agitation and rotation of the filter components are opposite, achieving scraping and cleaning of the filter screen's interior. The rotating shaft also drives the scraping frame to clean and transport impurities. During treatment, the drive component adjusts the rotation of the filter screen, driving related components to agitate the water. This, combined with ultraviolet germicidal lamps or disinfectant, enhances the disinfection effect. After drainage, the first and second regulating valves control the drainage and impurity discharge, enabling the device to automatically clean the filter screen for convenient and rapid deployment, further improving the efficiency of ballast water treatment.

Description

Technical Field

[0001] This invention relates to the field of ballast water treatment technology, and in particular to a device and system for treating ship ballast water with controllable flow rate. Background Technology

[0002] During ship operation, the treatment of ship ballast water is of paramount importance. In order to comply with international conventions and environmental protection requirements, a series of treatments must be carried out on ship ballast water to remove or kill any harmful organisms and pathogens that may be carried in it, prevent ecological damage and biological invasion between different sea areas, and remove suspended solids, oil and other impurities 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] Chinese patent with announcement number "CN220412964U" discloses a UV disinfection device for LED lamps in ship ballast water. The device utilizes a structure including an anti-reflective outer shell, an inner shell, a current regulating component, a light-transmitting sleeve, and an LED lamp assembly. It uses LED UV lamps for disinfection, overcoming the problems of fragility and environmental pollution associated with traditional UV lamps. It also controls the floor space occupied and reduces hydraulic loss and energy consumption.

[0004] However, this device has obvious defects in practical applications. Although it has disinfection and sterilization functions, it lacks effective cleaning measures for the filter screen. When treating ballast water, as impurities are continuously filtered out, the filter screen is easily clogged. The device can only be cleaned by removing the filter screen, which means that the equipment needs to be stopped for a long time until the cleaning is completed and the filter screen is reinstalled before it can be put back into use. The whole process is time-consuming and seriously affects the efficiency of the equipment. It is urgent to improve the treatment efficiency of ship ballast water. Summary of the Invention

[0005] The purpose of this invention is to provide a treatment device for ship ballast water with controllable flow rate, so as to solve the problem mentioned in the background art that the prior art cannot be quickly cleaned and put back into use.

[0006] To achieve the above objectives, the present invention provides a controllable flow rate treatment device for ship ballast water, comprising a base, supporting legs fixedly installed in a ring at equal intervals on the top of the base, a top ring fixedly installed on the top of the supporting legs, a treatment tank fixedly installed on the inner side of the top ring, a filter mechanism provided on the top of the top ring, the bottom of the filter mechanism extending into the interior of the treatment tank, a first regulating valve fixedly installed in the middle of the bottom of the treatment tank, a second regulating valve fixedly installed on one side of the bottom of the treatment tank, and ultraviolet germicidal lamps fixedly installed in a ring at equal intervals inside the treatment tank, the input end of the second regulating valve being connected to the bottom of the treatment tank.

[0010] Furthermore, the drive assembly includes a gear ring and a first motor. The gear ring is fixedly installed on the outside of the filter screen, and the first motor is fixedly installed on the bottom side of the top ring. A gear is fixedly installed through the top output end of the first motor and the gear is meshed with the gear ring. A transmission group is provided on the top of the gear, and the transmission group is connected to the internal agitation assembly.

[0011] Furthermore, the transmission assembly includes a connecting shaft and a support frame. The support frame is fixedly installed in the middle of the inner side of the annular water-blocking enclosure. The connecting shaft is fixedly installed on the top of the gear. Both the top of the gear and the top of the support frame are rotatably connected to synchronous pulleys. The synchronous pulleys are connected to each other by a synchronous belt drive. The bottom of the synchronous pulley located on the support frame is connected to the top of the internal agitation assembly.

[0012] Furthermore, the internal agitation assembly includes a rotating shaft, which is rotatably connected to the bottom center of the support frame. The top of the rotating shaft is connected to the bottom of the synchronous wheel located on the support frame. A first auger is fixedly installed on the upper part of the outer surface of the rotating shaft, and a second auger is fixedly connected to the lower part of the outer surface of the rotating shaft. The first auger is also conical and rotatably connected to the inside of the filter screen cover, and the second auger is rotatably connected to the inside of the filter screen cylinder.

[0013] Furthermore, the upper part of the outer surface of the rotating shaft is also fixedly connected with scraper frames arranged in a ring at equal intervals. The scraper frames are located on the outside of the first auger, and the outer surface of the scraper frames is in close contact with the inner wall of the filter screen.

[0014] Furthermore, the external agitation assembly includes a spiral agitator blade and a connecting arm. The spiral agitator blade is arranged in a ring at equal intervals and fixedly installed on the bottom outer side of the filter screen. The connecting arm is arranged in a ring at equal intervals and fixedly installed on the bottom of the filter screen and located on the inner side of the spiral agitator blade.

[0015] Furthermore, a support ring is fixedly connected to the bottom of the stirring plate located on the inner side of the connecting arm, and the support ring is rotatably connected to the outer side of the filter screen cylinder.

[0016] A controllable flow rate ballast water treatment system for ships includes a filtration module, a sterilization and disinfection module, a separation module, a monitoring and control module, and a ballast pump pipeline module. The filtration module is connected to the sterilization and disinfection module through the ballast pump pipeline module, and the sterilization and disinfection module is connected to the separation module through the ballast pump pipeline module. The monitoring and control module is electrically connected to the filtration module, the sterilization and disinfection module, the separation module, and the ballast pump pipeline module.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] Firstly, in this invention, the ballast water treatment process is optimized by setting up a filtration mechanism. In use, the ballast water is connected to the ballast water pipeline via the connecting flange on the outside of the connecting pipe, and the ballast water is transported through the connecting pipe and the conveying pipe. The flow rate is controlled by the flow regulating valve to prevent water from overflowing the annular water-blocking enclosure. The filter screen and filter cylinder of the filtration mechanism filter the ballast water. At the same time, the ultraviolet germicidal lamp is activated to irradiate and sterilize the inside of the treatment tank. During the sterilization process, the drive motor drives the gear to rotate, causing the gear ring to rotate, which in turn drives the filter screen and the filter cylinder at the bottom to rotate on the top of the treatment tank. This effectively prevents the filtered impurities from covering the outer surface of the filter cylinder, improves the filtration efficiency, prevents clogging, and improves the ballast water treatment efficiency.

[0019] Secondly, in this invention, the device function is enhanced by setting the drive mechanism and transmission components to work closely together. When the drive motor is started, the gear drive ring rotates, causing the connecting shaft and the top synchronous pulley to rotate. Through the synchronous belt drive, the top synchronous pulley and the bottom rotating shaft of the support frame rotate, thereby driving the first and second augers to rotate inside the filter screen cover and filter screen cylinder, and to perform scraping and cleaning inside. Since the gear and the gear ring drive in opposite directions, and the gear drives the synchronous pulley in the same direction, the stirring component and the filter component rotate in opposite directions, which helps to squeeze and discharge the filter material, achieving 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 convey impurities downward.

[0020] Thirdly, in this invention, during the processing, the rotation of the filter screen is adjusted by the drive component, which drives the bottom spiral agitator, connecting arm, and agitator plate to rotate, thus stirring the water in the treatment tank and promoting efficient water flow. Combined with the ultraviolet germicidal lamp, it can quickly and evenly disinfect. When disinfectant is needed, stirring can make the disinfectant and water evenly mixed, improving the disinfection effect. When draining, the first regulating valve is closed and the second regulating valve is opened. After the drainage is completed, the first regulating valve is opened, and the first and second screw conveyors drive the impurities to be discharged from the first discharge valve. After the ballast water is treated, the device can automatically clean the filter screen and filter cylinder. Opening the first solenoid valve can discharge the impurities, improving the cleaning effect and allowing the device to be put into use quickly, further improving the overall ballast water treatment efficiency.

[0030] Example

[0031] Please see Figures 1-8 In this embodiment of the invention, a controllable flow rate treatment device for ship ballast water includes a base 1, with support legs 2 fixedly installed in a ring at equal intervals on the top of the base 1, a top ring 3 fixedly installed on the top of the support legs 2, a treatment tank 4 fixedly installed on the inner side of the top ring 3, a filter mechanism 6 provided on the top of the top ring 3, the bottom of the filter mechanism 6 extending into the interior of the treatment tank 4, a first regulating valve 7 fixedly installed in the middle of the bottom of the treatment tank 4, a second regulating valve 8 fixedly installed on one side of the bottom of the treatment tank 4, and ultraviolet germicidal lamps 5 fixedly installed in a ring at equal intervals inside the treatment tank 4. The input end of the second regulating valve 8 is connected to the bottom of the interior of the treatment tank 4.

[0032] The filtration mechanism 6 includes a filter screen 61 and a flow regulating component 62. The filter screen 61 is conical in shape and rotatably connected to the top of the treatment tank 4. A drive component 63 is provided on the outside of the filter screen 61, and an internal agitator 64 is provided inside the filter screen 61. The internal agitator 64 and the drive component 63 are connected in a transmission manner. An external agitator 65 is fixedly installed on the bottom outside of the filter screen 61, and a filter cylinder 66 is fixedly installed on the bottom of the filter screen 61. The bottom of the filter cylinder 66 is rotatably connected to and communicates with the top of the first regulating valve 7. The flow regulating component 62 is installed on the top of the top ring 3 and is located outside the drive component 63. When the device is working, the ballast water to be treated enters from the top of the filtration mechanism 6. In the filtration mechanism 6, the conical filter screen 61 can... The top of the treatment tank 4 rotates, driven by the outer drive component 63. The drive component 63 is also connected to the inner agitator component 64, allowing the inner agitator component 64 to operate inside the filter screen 61. When the ballast water passes through the filter screen 61 and the filter cylinder 66 connected to the bottom, larger particles are intercepted and filtered. The flow regulating component 62 at the top of the top ring 3 can control the flow rate of the ballast water. During the filtration process, the ultraviolet germicidal lamps 5 arranged in a ring at equal intervals inside the treatment tank 4 sterilize and disinfect the ballast water. The outer agitator component 65 on the outside of the bottom of the filter screen 61 and the inner agitator component 64 can agitate the ballast water during filtration, improving the filtration effect. When drainage is required, different drainage operations can be achieved by controlling the first regulating valve 7 and the second regulating valve 8.

[0033] Please see Figures 1-8The flow regulating component 62 includes an annular water-blocking enclosure 621, which is fixedly installed on the outer top of the top ring 3. An inner frame 622 is fixedly installed on one side of the upper inner end of the annular water-blocking enclosure 621. A conveying pipe 623 is fixedly installed on the inner side of the inner frame 622. A flow regulating valve 624 is fixedly installed on the outer end of the conveying pipe 623. A connecting pipe 625 is fixedly connected to the top of the flow regulating valve 624. A connecting flange 626 is fixedly installed on the outer side of the connecting pipe 625. Mounting holes 627 are evenly spaced and arranged in a ring on the outer side of the connecting flange 626. The mounting holes 627 are countersunk holes. The annular water-blocking enclosure 621, fixed on the outer top of the top ring 3, serves to prevent ballast water from overflowing, ensuring that the water flows within a specified area. The inner frame 622 is installed on the annular water-blocking enclosure. The upper side of the inner part of the baffle 621 provides a stable support for the delivery pipe 623, which is responsible for introducing ballast water into the treatment device. The flow regulating valve 624 is installed at the outer end of the delivery pipe 623. By adjusting its opening, the delivery flow of ballast water can be precisely controlled. The connecting pipe 625 is connected to the top of the flow regulating valve 624 and is the channel for ballast water to enter the delivery pipe 623. The connecting flange 626 on the outer side of the connecting pipe 625 is used to connect with the external ballast water pipeline. The countersunk holes arranged in a ring at equal intervals on its outer side allow the heads of the mounting bolts to be sunk into them, ensuring a flat connection surface. This facilitates the use of bolts to firmly fasten the connecting flange 626 to the external pipeline flange, thereby achieving a stable connection between the entire device and the external ballast water system, laying the foundation for subsequent ballast water flow regulation and treatment processes.

[0034] Please see Figures 3-6The drive assembly 63 includes a gear ring 631 and a first motor 632. The gear ring 631 is fixedly installed on the outside of the filter screen 61, and the first motor 632 is fixedly installed on one side of the bottom of the top ring 3. A gear 633 is fixedly installed through the top ring 3 at the top output end of the first motor 632. The gear 633 and the gear ring 631 are meshed together. A transmission assembly 634 is provided on the top of the gear 633. The transmission assembly 634 is connected to the internal agitation assembly 64. The transmission assembly 634 includes a connecting shaft 6341 and a support frame 6342. The support frame 6342 is fixedly installed in the middle of the inner side of the annular water-blocking enclosure 621. The connecting shaft 6341 is fixedly installed on the top of the gear 633. Both the top of the gear 633 and the top of the support frame 6342 are rotatably connected to synchronous pulleys 6343, which are connected by a synchronous belt drive. The bottom of the synchronous pulley 6343 on the support frame 6342 is connected to the top of the internal agitator 64. When the device starts working, the first motor 632 starts, and its top output end drives the gear 633 to rotate. The gear 633 meshes with the gear ring 631 fixed to the outside of the filter screen 61. The rotation of the gear 633 drives the gear ring 631 to rotate, thereby causing the filter screen 61 to rotate. This prevents impurities from accumulating locally on the filter screen 61 and the filter cylinder 66, improving filtration efficiency. Simultaneously, the transmission assembly 634 at the top of the gear 633 participates in the operation. The connecting shaft 6341 is fixed to the top of the gear 633. The gear 633 and the synchronous pulley 6343 at the top of the support frame 6342 are connected by a synchronous belt. 6342 is fixed in the middle of the inner side of the annular water-blocking enclosure 621. When the gear 633 rotates, it drives the synchronous pulley 6343 on the support frame 6342 to rotate through the synchronous belt drive, thereby transmitting power to the internal stirring component 64, so that the internal stirring component 64 performs corresponding actions inside the filter screen cover 61, realizing that the internal stirring component 64 and the filter screen cover 61 rotate in opposite directions, thereby assisting in cleaning the inside of the filter screen cover 61 and the filter screen cylinder 66, and promoting water flow stirring to enhance the filtration and treatment effect.

[0035] Please see Figures 5-8The internal agitator 64 includes a rotating shaft 641, which is rotatably connected to the bottom center of the support frame 6342. The top of the rotating shaft 641 is connected to the bottom of the synchronous pulley 6343 located on the support frame 6342. A first auger 642 is fixedly installed on the upper part of the outer surface of the rotating shaft 641, and a second auger 643 is fixedly connected to the lower part of the outer surface of the rotating shaft 641. The first auger 642 is also conical and rotatably connected to the inner side of the filter screen cover 61. The second auger 643 is rotatably connected to the inside of the filter screen cylinder 66. Scraping frames 68 are also fixedly connected in a ring at equal intervals on the upper part of the outer surface of the rotating shaft 641. The scraping frames 68 are located outside the first auger 642, and their outer surfaces are in close contact with the inner wall of the filter screen cover 61. When the drive assembly 63 is working, the rotating shaft 641 located in the center of the bottom of the support frame 6342 receives energy from the synchronous pulley 6343 on the support frame 6342. Powered by the 43, the shaft 641 begins to rotate. The first auger 642, fixed at the upper end, and the second auger 643, fixed at the lower end, also rotate. The first auger 642 is conical and rotatably connected to the inside of the filter screen 61, while the second auger 643 rotates inside the filter cylinder 66. Their rotation agitates and cleans the impurities inside the filter screen 61 and filter cylinder 66. Simultaneously, the scraping frames 68, arranged in a ring at equal intervals on the upper end of the outer surface of the shaft 641, are in close contact with the inner wall of the filter screen 61. As the shaft 641 rotates, the scraping frames 68 scrape and clean the inner wall of the filter screen 61, helping to prevent impurities from adhering to the inner wall of the filter screen 61 and further enhancing the cleaning effect. This ensures that the filter screen 61 and filter cylinder 66 will not be affected by the accumulation of impurities during the filtration process, thus guaranteeing the efficient operation of the entire ship's ballast water treatment device.

[0036] Please see Figures 5-6The external agitator 65 includes spiral agitator blades 651 and connecting arms 652. The spiral agitator blades 651 are arranged in a ring at equal intervals and fixedly installed on the bottom outer side of the filter screen cover 61. The connecting arms 652 are arranged in a ring at equal intervals and fixedly installed on the bottom of the filter screen cover 61 and located inside the spiral agitator blades 651. Agitator plates 653 are fixedly installed at equal intervals on the bottom of the connecting arms 652. A support ring 67 is fixedly connected to the bottom of the agitator plates 653 located inside the bottom of the connecting arms 652. The support ring 67 is rotatably connected to the outside of the filter screen cylinder 66. As the filter screen cover 61 rotates, the spiral agitator blades 651, which are arranged in a ring at equal intervals on the bottom outer side of its bottom, rotate together. During the rotation of the spiral agitator blades 651, the agitator blades 651 agitate the bottom of the processing tank 4 near the bottom of the filter screen cover 61. The water in the outer region is agitated, promoting its flow. Simultaneously, the connecting arms 652, which are evenly spaced at the bottom of the filter screen 61 and located inside the spiral agitator 651, also rotate with the filter screen 61. The agitator plates 653, which are evenly spaced at the bottom of the connecting arms 652, further agitate the water during rotation, enhancing the flow and mixing effect. In addition, the agitator plates 653 on the inner bottom of the connecting arms 652 are rotatably connected to the outer side of the filter screen cylinder 66 through the support ring 67. This provides a certain stability to the entire external agitation assembly 65 and helps guide the water to the filter screen cylinder 66 during rotation, allowing the ballast water to pass through the filter screen cylinder 66 more smoothly for filtration. Overall, this improves the agitation and filtration efficiency of the water in the treatment tank 4.

[0037] A controllable flow rate ballast water treatment system for ships includes a filtration module, a sterilization and disinfection module, a separation module, a monitoring and control module, and a ballast pump pipeline module. The filtration module is connected to the sterilization and disinfection module via the ballast pump pipeline module, and the sterilization and disinfection module is connected to the separation module via the ballast pump pipeline module. The monitoring and control module is electrically connected to the filtration module, sterilization and disinfection module, separation module, and ballast pump pipeline module. In operation, the ballast water is first transported to the filtration module via the ballast pump pipeline module. The filtration module removes impurities such as suspended particles from the water, initially purifying the water quality. Subsequently, the water is further purified... The treated water flows through the ballast pump pipeline module to the sterilization and disinfection module, which uses chemical or physical methods to kill harmful organisms and pathogens in the water, ensuring water quality safety. Then, the sterilized and disinfected water enters the separation module through the ballast pump pipeline module to further separate residual oil, water, and solid-liquid components, improving water purity. Throughout 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. Based on the monitoring data, it adjusts the operating status of each module in a timely manner to ensure stable and efficient system operation, achieving comprehensive and precise treatment of ship ballast water.

[0038] The working principle of this invention is as follows: By setting up a filtration mechanism 6, when this device is put into use, it can be connected to the ballast water pipeline via the connecting flange 626 on the outside of the connecting pipe 625. Then, ballast water is transported through the connecting pipe 625 and the conveying pipe 623. During this process, the flow rate of the ballast water can be adjusted using the flow regulating valve 624 to prevent the ballast water from overflowing the annular water-blocking enclosure 621. In the ballast water filtration stage, the filter screen 61 and the filter cylinder 66 of the filtration mechanism 6 are used to perform filtration. At the same time, the ultraviolet germicidal lamp 5 is turned on to irradiate the inside of the treatment tank 4 to achieve a better sterilization effect. During the sterilization process, the drive motor is started, driving the gear 633 to rotate, which in turn drives the gear ring 631 to rotate, causing the filter screen 61 to rotate at the top of the treatment tank 4. With the rotation of the filter screen 61 and the filter cylinder 66 at its bottom, the filtered impurities can be prevented from covering the outer surface of the filter cylinder 66, effectively improving the overall filtration efficiency, preventing clogging, and thus improving the ballast water treatment efficiency.

[0039] By setting up a drive mechanism and transmission assembly 634 components that work together, in use, starting the drive motor drives 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 pulley 6343 to rotate. When the synchronous pulley 6343 rotates, it drives the synchronous pulley 6343 at the top of the support frame 6342 to rotate via a synchronous belt drive, which in turn 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 move in the filter screen 61 and through the filter screen 62. The filter screen cylinder 66 rotates internally, scraping and cleaning its interior. It's worth noting that during the cleaning process, gear 633 and gear ring 631 drive in opposite directions, causing the filter screen cover 61 to rotate clockwise. Meanwhile, gear 633 drives two synchronous pulleys 6343 in the same direction, which in turn drives the bottom connecting shaft 6341 to drive the first auger 642 and the second auger 643 to rotate in opposite directions. This opposite rotation of the agitator and filter components helps to squeeze and discharge the filtered material, achieving a better cleaning effect. Simultaneously, the rotation of the drive shaft 641 also drives the scraping frame 68 on its outer surface to rotate. The scraping frame 68 rotates against the inner wall of the filter screen cover 61, cleaning the filter screen. The inner wall of the cover 61 is cleaned by scraping, and the impurities filtered out inside the filter cylinder 66 are conveyed downwards to prevent the filter cover 61 and the filter cylinder 66 from clogging. During the process, the rotation of the filter cover 61 drives the bottom spiral agitator 651 to rotate. While the spiral agitator 651 rotates, it also drives the bottom connecting arm 652 and agitator plate 653 to rotate and agitate, stirring the water in the treatment tank 4 and promoting efficient flow of the water. This stirring function, combined with the ultraviolet germicidal lamp 5, helps to quickly and evenly disinfect. When disinfectant is needed, the disinfectant can be evenly mixed with the water in the treatment tank 4, improving the disinfection effect. In effect, during drainage, the first regulating valve 7 is closed and the second regulating valve 8 is opened for drainage; after drainage is completed, the first regulating valve 7 is opened, and the impurities inside the filter screen 61 and filter cylinder 66 are driven downward by the first auger 642 and the second auger 643, so that the filtered impurities can be discharged from the first discharge valve. It can be seen that after completing the ballast water treatment, this device can automatically scrape and remove the impurities inside the filter screen 61 and filter cylinder 66. Only the first solenoid valve needs to be opened to discharge the filtered impurities, which improves the cleaning effect during the use of this device, allows the device to be put into use quickly, and further enhances the overall treatment efficiency of the equipment for ballast water.
