Description

Technical Field

[0001] This utility model belongs to the field of ship ballast water technology, and specifically relates to an installation structure for a ship ballast water system. Background Technology

[0002] In ship ballast water management systems, filters are key components that ensure the normal operation of the system. Their main function is to intercept impurities in the water and prevent pipe blockage and equipment damage. However, the existing installation structure of ship ballast water systems has obvious shortcomings. Currently, filter installation is mostly done by bolting or welding. Maintenance requires the use of various professional tools, and the operation process is cumbersome, involving the disassembly and installation of a large number of parts. This complicated disassembly and assembly process not only consumes a lot of time and manpower, but also the frequent operation can easily lead to wear of seals, increase the risk of system leakage, and pose a hidden danger to the safe operation of the ship.

[0003] Furthermore, existing technologies generally lack effective filter screen cleaning functions. During ship navigation, impurities such as silt, algae, and plankton in ballast water easily adhere to the filter screen surface, gradually accumulating and clogging the mesh over time. When the filter screen is clogged, the system pressure loss increases and the flow rate decreases significantly, seriously affecting the working efficiency of the ballast water system. Although some systems are equipped with backwashing pipes, the cleaning power is insufficient and it is difficult to completely remove stubborn deposits. Due to the lack of efficient cleaning methods, the filter screen needs to be replaced frequently, increasing maintenance costs and ship downtime, which is seriously inconsistent with the high-efficiency and low-maintenance operation requirements of modern ships. It is evident that existing technologies have certain defects and shortcomings, and therefore, they need to be improved and redesigned. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a ship ballast water system installation structure to solve the problem that the overall inspection and maintenance is relatively cumbersome and inconvenient during the application of the existing technology.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A ship ballast water system installation structure includes a treatment tank, an installation mechanism fixedly installed on one side of the treatment tank, a filter mechanism fixedly installed on the top of the installation mechanism, the filter end of the filter mechanism being inserted into the top of the treatment tank, a drain hopper fixedly installed at the bottom of the treatment tank, and a drain valve fixedly installed at the output end of the drain hopper.

[0007] The installation mechanism includes a rail frame, which is fixedly installed in the middle of the back of the processing box. A drive motor is fixedly installed at the bottom of the rail frame. A lead screw is fixedly installed through the output end of the drive motor through the rail frame. The lead screw is rotatably connected to the inside of the rail frame. A slider is threadedly connected to the outer surface of the lead screw. A connecting arm is fixedly connected to the top of the slider. The top of the connecting arm is connected to the filter mechanism.

[0008] Furthermore, the filtration mechanism includes a sealing cover covering the top of the treatment tank. A water inlet is fixedly connected to the top of the sealing cover, and a filter frame is fixedly installed at the bottom of the sealing cover. A filter assembly is movably installed inside the filter frame, and a cleaning assembly is rotatably connected to the top of the filter frame. The cleaning end of the cleaning assembly covers the outside of the filter assembly.

[0009] Furthermore, the slider has a convex shape when viewed from above, and the overall cross-sectional shape of the internal cavity of the rail frame is also convex.

[0010] Furthermore, a connecting hose is fixedly installed on the top of the water inlet hopper, and a water inlet flange is fixedly connected to the outer end of the connecting hose.

[0011] Furthermore, the filter assembly includes a guide rail, which is fixedly installed on the lower ends of both sides inside the filter frame. A slide bar is slidably connected inside the guide rail, and a collection drawer is fixedly connected to the inner side of the slide bar. A filter screen is fixedly installed in the middle of the collection drawer, and the bottom of the filter screen extends through the collection drawer.

[0012] Furthermore, a sealing side plate is fixedly installed on the outside of the collection drawer, and the sealing side plate covers the outside of the filter frame.

[0013] Furthermore, the cleaning assembly includes a mounting frame, which is fixedly installed at the top of the water inlet hopper. A spiral drive blade is rotatably connected to the bottom of the mounting frame. Elastic brush plates are fixedly installed at equal intervals in a ring at the bottom of the spiral drive blade. The filter screen is generally conical in shape, and the elastic brush plates are generally inclined. The inclination direction of the elastic brush plates is parallel to the conical surface of the filter screen. The cleaning brushes on the inner side of the elastic brush plates are in contact with the outer surface of the filter screen.

[0014] In summary, the present invention has the following main advantages:

[0015] Firstly, this device is easy to assemble and disassemble. The installation mechanism allows for convenient installation and removal of the filter mechanism. The drive motor rotates the lead screw, and the U-shaped slider matches the rail cavity, allowing for stable up and down sliding. The connecting arm drives the filter mechanism to lift and lower as a whole. During maintenance, the motor drives the slider to rise and pull out components such as the sealing cover and filter frame. Then, by pulling the slide bar of the collection drawer, the filter screen can be quickly removed. The elastic brush plate is made of elastic material and adapts to deformation when pulled out, making it easy to pull out quickly. This structure requires no additional tools. Through motor drive and slide rail sliding, the filter screen can be disassembled and assembled in a short time, improving maintenance efficiency and reducing manual difficulty and the risk of damage to seals.

[0016] Secondly, in terms of automatic flushing using water flow, the cleaning components of the filtration mechanism achieve automatic cleaning with the help of water flow. Ballast water enters the inlet hopper, impacting the rotating spiral drive blades, which in turn rotate the bottom elastic brush plate. Because the inclined direction of the elastic brush plate is parallel to the conical surface of the conical filter screen, and the inner brush is in contact with the surface of the filter screen, the filter screen can be cleaned in all directions. The brushed-off impurities enter the collection drawer with the water flow. This mechanism does not require an additional power source, continuously cleans the filter screen, reduces the accumulation of impurities, extends the life of the filter screen, reduces the replacement frequency, ensures the stable operation of the ballast water system, and avoids the decrease in efficiency caused by clogging.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please refer to Figure 1-4 The embodiment of the ship ballast water system installation structure includes a treatment tank 1, an installation mechanism 2 is fixedly installed on one side of the treatment tank 1, a filter mechanism 3 is fixedly installed on the top of the installation mechanism 2, the filter end of the filter mechanism 3 is inserted into the top of the treatment tank 1, a drain bucket 4 is fixedly installed on the bottom of the treatment tank 1, and a drain valve 5 is fixedly installed on the output end of the drain bucket 4.

[0025] The mounting mechanism 2 includes a rail frame 21, which is fixedly installed in the middle of the back of the processing box 1. A drive motor 22 is fixedly installed at the bottom of the rail frame 21. A lead screw 23 is fixedly installed through the rail frame 21 at the output end of the drive motor 22. The lead screw 23 is rotatably connected to the inside of the rail frame 21. A slider 24 is threadedly connected to the outer surface of the lead screw 23. A connecting arm 25 is fixedly connected to the top of the slider 24. The top of the connecting arm 25 is connected to the filter mechanism 3. During use, when it is necessary to install or disassemble the filter mechanism 3, the drive motor 22 at the bottom of the rail frame 21 is started, and the motor output end drives the lead screw 23 to move along the rail. The filter mechanism 3 rotates within the frame 21. Due to the threaded connection between the lead screw 23 and the slider 24, and the fact that the slider 24 is convex and matches the convex cavity of the frame 21, the slider 24 slides stably up and down within the frame 21. The connecting arm 25 at the top of the slider 24 moves synchronously, thereby driving the filter mechanism 3 to rise or fall as a whole. When the filter mechanism 3 rises, its filter end is pulled out from the top of the treatment box 1 for easy maintenance or replacement of parts. When the filter mechanism 3 falls, its filter end is inserted into the top of the treatment box 1 to achieve ballast water filtration. The treated water is discharged from the system through the drain hopper 4 at the bottom of the treatment box 1 and the drain valve 5.

[0026] Please refer to Figures 1-4The filtration mechanism 3 includes a sealing cover 31, which covers the top of the treatment tank 1. A water inlet hopper 32 is fixedly connected to the top of the sealing cover 31, and a filter frame 33 is fixedly installed at the bottom of the sealing cover 31. A filter assembly 34 is movably installed inside the filter frame 33. A cleaning assembly 35 is rotatably connected to the top of the filter frame 33, and the cleaning end of the cleaning assembly 35 covers the outside of the filter assembly 34. The slider 24 has a U-shaped top view, and the overall cross-sectional shape of the internal cavity of the rail frame 21 is also U-shaped. A connecting hose 36 is fixedly installed on the top of the water inlet hopper 32, and a water inlet flange 37 is fixedly connected to the outer end of the connecting hose 36. During the operation of this device, its ballast water enters the connecting hose 36 through the water inlet flange 37, and then flows into the filter frame 33 below the sealing cover 31 through the water inlet hopper 32. The filter assembly 34 inside the filter frame 33... Impurities are intercepted in the water flow, and the purified water is discharged through the drain hopper 4 and drain valve 5. During this process, the water flow impacts the spiral drive blade 352 of the cleaning component 35, causing the bottom elastic brush plate 353 to rotate. Because its tilt direction is parallel to the cone surface of the conical filter screen 344 and the brush is in contact with the surface of the filter screen, it can automatically brush the impurities on the filter screen. The brushed-off impurities enter the collection drawer 343 with the water flow. When maintenance is required, the drive motor 22 of the mounting mechanism 2 drives the lead screw 23 to rotate, causing the U-shaped slider 24 to slide in the U-shaped cavity of the rail frame 21. The filter mechanism 3 is displaced from the top of the treatment box 1 through the connecting arm 25. Then, the slide bars 342 on both sides of the collection drawer 343 can be pulled to quickly remove the filter screen 344 for cleaning or replacement. The whole process does not require additional tools, realizing a high-efficiency combination of convenient disassembly and automatic cleaning.

[0027] Please refer to Figures 2-3The filter assembly 34 includes a guide rail 341, which is fixedly installed on the lower ends of both sides inside the filter frame 33. A slide bar 342 is slidably connected inside the guide rail 341. A collection drawer 343 is fixedly connected to the inner side of the slide bar 342. A filter screen cover 344 is fixedly installed in the middle of the collection drawer 343, with the bottom of the filter screen cover 344 penetrating through the collection drawer 343. A sealing side plate 345 is fixedly installed on the outer side of the collection drawer 343, covering the outer side of the filter frame 33. The cleaning assembly 35 includes a mounting bracket 351. 1. Fixedly installed at the top of the inlet hopper 32, the bottom of the mounting bracket 351 is rotatably connected to a spiral drive blade 352. Elastic brush plates 353 are fixedly installed at equal intervals in a ring at the bottom of the spiral drive blade 352. The filter screen 344 is generally conical in shape, and the elastic brush plates 353 are generally inclined. The inclination direction of the elastic brush plates 353 is parallel to the conical surface of the filter screen 344. The cleaning brushes on the inner side of the elastic brush plates 353 are in close contact with the outer surface of the filter screen 344. During the application of this device, when ship ballast water passes through the connection... The hose 36 and the inlet hopper 32 flow into the filter frame 33, first contacting the conical filter screen 344. The filter screen 344 intercepts impurities such as silt and algae in the water. The purified water enters the treatment tank 1 through the bottom of the filter screen 344 and is finally discharged through the drain hopper 4 and drain valve 5. Under the impact of the water flow, the spiral drive blade 352 installed at the top of the inlet hopper 32 begins to rotate, driving the elastic brush plates 353 arranged in a ring at equal intervals at the bottom to rotate. Since the inclined direction of the elastic brush plates 353 is parallel to the conical surface of the filter screen 344, and the inner side... The cleaning brush fits tightly against the filter screen surface and can thoroughly clean the curved surface of the filter screen during rotation, removing impurities attached to the filter screen surface. The removed impurities fall into the collection drawer 343 below with the water flow, preventing impurities from clogging the filter screen holes. When it is necessary to clean or replace the filter screen cover 344, simply pull the sealing side plate 345 on the outside of the collection drawer 343, so that the slide bar 342 slides along the guide rails 341 at the lower ends of both sides inside the filter frame 33, and the collection drawer 343 and the filter screen cover 344 can be pulled out together, which is convenient for quick maintenance and replacement.

[0028] Operating principle and advantages: During application, this device facilitates easy assembly and disassembly. The ballast water system installation structure allows for convenient installation and removal of the filter mechanism 3 via the installation mechanism 2. After the drive motor 22 starts, it drives the lead screw 23 to rotate. Since the lead screw 23 is threadedly connected to the slider 24, and the slider 24 is U-shaped and matches the U-shaped cavity of the rail frame 21, the slider 24 can slide stably up and down within the rail frame 21. The connecting arm 25 at the top of the slider 24 is connected to the filter mechanism 3. By controlling the forward and reverse rotation of the drive motor 22, the filter mechanism 3 can be driven to rise or fall as a whole. When maintenance or replacement of the filter assembly 34 is required, the drive motor 22 drives the slider 24 to rise, thus removing the sealing cover. 31. The filter frame 33 and its internal components are pulled out of the processing box 1. Then, the slide bars 342 on both sides of the collection drawer 343 are pulled to slide the filter frame 33 out along the guide rail 341, and the filter screen cover 344 can be quickly removed. During disassembly and assembly, due to the setting of the elastic brush plate 353, which is made of elastic material, it can adapt to deformation when the filter screen cover 344 is pulled out, making it easy to quickly pull out the filter screen cover 344. The whole structure is easy to clean and maintain quickly. It can be seen that this installation structure does not require additional tools. It can complete the disassembly and installation of the filter screen in a short time by simply driving the motor and sliding the slide rail, which greatly improves maintenance efficiency and reduces the difficulty of manual operation and the risk of damage to the seals.

[0029] During its application, this device utilizes water flow for automatic flushing. The cleaning component 35 in the filter mechanism 3 can achieve automatic cleaning with the help of water flow. Ballast water enters the inlet hopper 32 through the connecting hose 36 and the inlet flange 37. During the fall, it impacts the spiral drive blade 352, causing it to rotate. The elastic brush plates 353, which are evenly spaced at the bottom of the spiral drive blade 352, rotate accordingly. Because the tilt direction of the elastic brush plates 353 is parallel to the conical surface of the conical filter screen 344, and the inner cleaning brush is in contact with the filter screen surface, the brush plates can perform all-round brushing along the curved surface of the filter screen 344 when rotating, brushing off the attached mud, algae and other impurities. The impurities are carried by the water flow through the filter screen 344 into the collection drawer 343, avoiding clogging of the filter screen holes. This water flow-driven automatic flushing mechanism does not require an additional power source, continuously cleans the filter screen, reduces the accumulation of impurities, extends the service life of the filter screen 344, reduces the replacement frequency, and at the same time ensures the stable operation of the ballast water system, avoiding the problem of reduced system efficiency due to filter screen clogging.
