Abstract

The application discloses an anti-heeling pump with a blockage prevention function, and relates to the application field of the anti-heeling pump of a ship. The anti-heeling pump comprises a bidirectional axial flow pump, and a blockage prevention purification system is arranged on the side of the bidirectional axial flow pump. The blockage prevention purification system comprises a water inlet filter screen, a filtering mechanism, a flocculent filtering assembly and a coarse filter cylinder. The blockage prevention purification system is arranged at both ends of the bidirectional axial flow pump, and impurities in ballast water are filtered. When water in a right ballast water tank is transported to a left ballast water tank, the ballast water enters the water inlet pipe of the right blockage prevention purification system, is filtered by the water inlet filter screen, enters the axial flow pump, then enters the left blockage prevention purification system, and reversely flushes the water inlet filter screen of the left blockage prevention purification system. Subsequently, the ballast water is discharged from the water outlet pipe of the left blockage prevention purification system and enters the left ballast water tank. In the whole operation process of the pump set, the ballast water flowing through the axial flow pump is filtered by the water inlet filter screen, and damage of impurities to the pump body is reduced.

Description

Technical Field

[0001] This invention relates to the field of anti-roll pumps for ships, specifically an anti-roll pump with anti-clogging function. Background Technology

[0002] Ship anti-heel devices are specialized equipment used to reduce or correct heeling (panning) that occurs during navigation, loading / unloading, and berthing, ensuring ship stability, navigation safety, and operational efficiency. Their core function is to actively or passively adjust the ship's center of gravity or buoyancy distribution to balance lateral moments and prevent dangerous situations (such as capsizing) or disruptions to normal operations caused by excessive heeling.

[0003] The main anti-heeling device for ships is the ballast water regulation system, which is the most basic and widely used anti-heeling device. It involves installing pipelines and pump sets between the ballast tanks on both sides of the ship. Ballast water is pumped from one side to the other according to the heeling condition, using the weight of the water to change the ship's lateral center of gravity distribution, thereby counteracting the heeling moment. Its characteristics include simple structure, low cost, and applicability to various types of ships (such as cargo ships and oil tankers). However, its regulation speed is relatively slow, making it suitable for dealing with slowly changing heeling conditions (such as weight imbalances during loading and unloading). The pump sets in the ballast water regulation system typically use centrifugal pumps or axial flow pumps to transport ballast water. Bidirectional axial flow pumps can directly change the impeller rotation direction by reversing the motor, achieving bidirectional ballast water transport (left tank → right tank or right tank → left tank) without relying on external valve switching. Its design goal is to provide stable output flow and head in both directions, meeting the "bidirectional regulation" requirement of the anti-heeling system.

[0004] When a ship is on a long voyage, its ballast water is drawn from external water bodies (mainly seawater, with some freshwater). Therefore, impurities in the aquatic environment will be directly introduced during the water intake process. Over a long period of time, these impurities will accumulate in the ballast water tank and form sediment. When such ballast water flows in the axial flow pump, the impurities in the ballast water will also cause the pump impeller to become entangled and damage the pump body. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide an anti-tilting pump with anti-clogging function to solve the technical problems mentioned in the background above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-clogging tilting pump with anti-clogging function, comprising a bidirectional axial flow pump, wherein an anti-clogging purification system is provided on the side of the bidirectional axial flow pump, the anti-clogging purification system comprising a movable pipe, an inlet water filter screen installed inside the movable pipe, and a three-way pipe connected to the bottom of the movable pipe, wherein a first one-way valve for connecting to the inlet water pipe is provided on the side of the three-way pipe, and a filter mechanism is connected to the bottom of the three-way pipe, the filter mechanism comprising a water inlet pan, and multiple sets of butterfly valves provided at the bottom of the water inlet pan, each of the multiple sets of butterfly valves having a flocculent material filter assembly at its bottom, ... The flocculent filter assembly has a drain pan at its bottom, and a second connecting pipe is connected to the bottom of the drain pan. A coarse filter cylinder is installed inside the second connecting pipe, and a third connecting pipe is connected to the side of the second connecting pipe. A second one-way valve for connecting to the outlet pipe is connected to the side of the third connecting pipe. Worm gears are connected to the sides of the multiple butterfly valves. Multiple worm gears are rotatably connected to the side of the upper water pan. The multiple worm gears mesh with the multiple worm gears respectively. A first friction disc is provided at both ends of the multiple worm gears. Multiple adjustment mechanisms for adjusting the rotation of the first friction discs are provided on the side of the upper water pan.

[0007] By adopting the above technical solution and installing anti-clogging purification systems at both ends of the bidirectional axial flow pump, impurities in the ballast water can be filtered, reducing the amount of impurities entering the axial flow pump and thus extending its service life. The anti-clogging purification system replaces the traditional inlet and outlet pipes (one pipe for inlet and outlet) with two sets of pipes, one for inlet and one for outlet. An inlet filter screen is installed at the connection point of the two sets of pipes, and electromagnetic check valves are installed in both sets of pipes for control. When water from the right ballast water tank is transferred to the left ballast water tank, the ballast water flows from the inlet of the right anti-clogging purification system. Water enters through the inlet pipe, is filtered by the inlet filter screen, and then enters the axial flow pump. Ballast water then enters the left-side anti-clogging purification system, which backwashes the inlet filter screen of the left-side anti-clogging purification system. Subsequently, it is discharged from the drain pipe of the left-side anti-clogging purification system into the left-side ballast water tank. In this way, during the overall operation of the pump unit, the ballast water flowing through the axial flow pump is filtered by the inlet filter screen, reducing the damage of impurities to the pump body. Furthermore, the ballast water backwashes the inlet filter screen during reciprocating transport, ensuring that the inlet filter screen always maintains a high-efficiency filtration effect.

[0008] The invention is further configured such that the bidirectional axial flow pump includes a pump tube, and a pump body impeller is rotatably connected inside the pump tube, and a drive device for driving the pump body impeller to rotate is installed on the top of the pump tube. The anti-clogging purification system also includes a first connecting pipe for connecting the pump tube and the movable pipe.

[0009] Preferably, by setting up a bidirectional axial flow pump, bidirectional adjustment of the ship's anti-roll system can be achieved. Compared with a unidirectional axial flow pump, it is not only easier to adjust, but also reduces the space occupied by the equipment.

[0010] The present invention is further configured such that both ends of the bidirectional axial flow pump are equipped with anti-clogging and purification systems. One set of anti-clogging and purification systems is connected to a second inlet pipe, a first outlet pipe and a set of ship ballast water tanks, and the other set of anti-clogging and purification systems is connected to a first inlet pipe, a second outlet pipe and another set of ship ballast water tanks. When the bidirectional axial flow pump operates in the forward direction, ballast water enters through the second inlet pipe and exits through the second outlet pipe. When the bidirectional axial flow pump operates in the reverse direction, ballast water enters through the first inlet pipe and exits through the first outlet pipe.

[0011] Preferably, by setting up an anti-clogging purification system, impurities in the ballast water can be filtered and collected, thereby purifying the ballast water and reducing the damage of impurities to the pump unit equipment.

[0012] The present invention is further configured such that a conical cylinder is installed inside the second connecting pipe, the conical cylinder extends into the interior of the coarse filter cylinder, and a plug is threaded to the bottom of the second connecting pipe for sealing the coarse filter cylinder.

[0013] Preferably, by setting a conical tube, ballast water can be discharged into the coarse filter tube. The coarse filter tube has a certain length, so that some larger impurities accumulate in the coarse filter tube.

[0014] The present invention is further configured such that the flocculent filtration assembly includes a sleeve, and multiple sets of drive impellers are rotatably connected inside the sleeve. The multiple sets of drive impellers are arranged in three layers from top to bottom. A set of drive impellers is arranged in the middle position of the first layer, and long nylon packing is arranged at the bottom of the set of drive impellers. The second and third layers each have four sets of drive impellers, and the drive impellers of the second and third layers are staggered. The bottom of the drive impellers of the second and third layers is arranged with short nylon packing. The length of the long nylon packing covers the length of the space where the drive impellers of the second and third layers are located.

[0015] Preferably, a flocculent filter assembly is used to filter and remove flocculent precipitates in the ballast water. The flocculent filter assembly is mainly composed of short nylon packing and long nylon packing. The long nylon packing is located in the middle, and two layers of short nylon packing are evenly distributed around the long nylon packing. The two layers of short nylon packing are staggered. This ensures the flow of ballast water and allows the packing to be evenly distributed to filter and adsorb flocculent impurities in the ballast water.

[0016] The invention is further configured such that the adjusting mechanism includes a housing, inside which are arranged two sets of first supports, which are vertically distributed and each set of first supports is rotatably connected to a first bevel gear on its side. Inside the housing, two sets of second supports are also movably installed via a limiting component, which are also vertically distributed and correspond to the two sets of first supports respectively. Each set of second supports is rotatably connected to a first square transmission shaft on its side, and the two sets of first square transmission shafts are movably connected through the two sets of first bevel gears respectively. Each set of first square transmission shafts has a second friction disc at its end, and a first spring is provided between the second friction disc and the corresponding first bevel gear.

[0017] Preferably, the opening and closing states of two sets of butterfly valves can be adjusted simultaneously by setting an adjustment mechanism. When one set of butterfly valves goes from open to closed, the adjacent butterfly valve will go from closed to open. In this way, the switching of the flocculent filter components can be carried out without stopping the equipment. The second friction disc is set to move and actively fit against the first friction disc, so that the adjustment mechanism can drive the two sets of butterfly valves to open / close at the same time.

[0018] The invention is further configured such that two sets of first spur gears are rotatably connected inside the housing, and a second bevel gear is provided at the bottom of each of the two sets of first spur gears. The two sets of second bevel gears mesh with the two sets of first bevel gears respectively. A second square transmission shaft is also provided inside the housing. A second spring is sleeved on the outside of the second square transmission shaft, and a linkage block for pressing the second bracket is movably installed on the outside of the second square transmission shaft. A guide rod is provided inside the housing. A third spring is sleeved on the outside of the guide rod, and a pressing block for pressing the linkage block is movably installed on the outside of the guide rod.

[0019] Preferably, by setting a linkage block and a pressing block, the pressing block can be adjusted to push the linkage block to move, and the movement of the linkage block can push the two sets of second supports to move, thereby realizing that the second supports drive the second friction disc to actively fit against the first friction disc.

[0020] The invention is further configured such that a second spur gear is rotatably connected inside the housing between two sets of first spur gears, the second spur gear meshes with the two sets of first spur gears, and a limiting groove is formed inside the second spur gear. A sleeve is rotatably connected to the top of the second spur gear, and two sets of fitting grooves are symmetrically formed on the side of the sleeve.

[0021] Preferably, by setting a second spur gear and a sleeve to drive the second friction disc to rotate and drive the first friction disc to rotate, the sleeve and the second spur gear are rotatably connected. Thus, when the operator installs the handle, the sleeve can be rotated so that its side fitting groove actively aligns with the spring pin of the handle, making the installation of the handle more convenient. The installation of the handle can be achieved by using the handle to push the extrusion block down.

[0022] The invention is further configured such that a throttle is movably mounted inside the second spur gear, the throttle is used to compress the extrusion block, the throttle matches the limiting groove, and two sets of spring pins mounted by springs are symmetrically arranged on the side of the throttle, and the spring pins match the fitting grooves on the side of the sleeve.

[0023] Preferably, by setting a throttle, the second friction disc of the adjustment mechanism can be actively engaged with the first friction disc by the squeezing insertion of the throttle, and the rotation of the throttle can make the second friction disc rotate and drive the first friction disc to rotate.

[0024] In summary, the present invention has the following main beneficial effects:

[0025] This invention utilizes anti-clogging and purification systems at both ends of a bidirectional axial flow pump to filter impurities in the ballast water, reducing the amount of impurities entering the pump and thus extending its service life. The anti-clogging and purification system replaces the traditional single inlet and outlet pipes with two sets of pipes, one inlet and one outlet. An inlet filter screen is installed at the junction of the two sets of pipes, and electromagnetic check valves control the flow. When water is transferred from the right ballast water tank to the left ballast water tank, the ballast water enters through the inlet pipe of the right-side anti-clogging and purification system. The ballast water is filtered by the inlet filter screen before entering the axial flow pump. Then, the ballast water enters the left anti-clogging purification system, which backwashes the inlet filter screen of the left anti-clogging purification system. Subsequently, it is discharged from the drain pipe of the left anti-clogging purification system into the left ballast water tank. In this way, during the overall operation of the pump set, the ballast water flowing through the axial flow pump is filtered by the inlet filter screen, reducing the damage of impurities to the pump body. Moreover, the ballast water backwashes the inlet filter screen during reciprocating transport, ensuring that the inlet filter screen always maintains a high-efficiency filtration effect.

[0026] This invention, through the installation of a filtration mechanism, a flocculent filtration component, and a coarse filter cylinder, can filter / collect impurities from the backwash inlet filter screen of ballast water discharge. This prevents accumulated impurities from re-entering the ballast water tank. The flocculent filtration component mainly consists of short nylon packing and long nylon packing. The long nylon packing is located in the middle, and two layers of short nylon packing are evenly distributed around the long nylon packing, with the two layers of short nylon packing being staggered. This ensures both the flowability of ballast water and the even distribution of packing to filter and adsorb flocculent impurities in the ballast water. Furthermore, the flocculent filtration component does not affect larger impurities, such as leaves, which can pass through. The relatively small amount of larger impurities is mainly collected by the coarse filter cylinder. Attached Figure Description

[0046] The embodiments of the present invention will now be described.

[0047] Please see Figure 1 - Figure 16An anti-clogging anti-tilt pump includes a bidirectional axial flow pump 1. An anti-clogging purification system is installed on the side of the bidirectional axial flow pump 1. The anti-clogging purification system includes a movable pipe 7, an inlet filter screen 8 installed inside the movable pipe 7, and a three-way pipe 9 connected to the bottom of the movable pipe 7. A first check valve 10 for connecting to the inlet pipe is installed on the side of the three-way pipe 9, and a filter mechanism 11 is connected to the bottom of the three-way pipe 9. The filter mechanism 11 includes an upper water tray 1101. The bottom of component 1 is equipped with multiple butterfly valves 1102, and each butterfly valve 1102 has a flocculent filter assembly 13 at its bottom. The flocculent filter assembly 13 is mainly used to filter and adsorb flocculent sediments in the ballast water. The bottom of the multiple flocculent filter assemblies 13 is equipped with a drain pan 1106. The upper water pan 1101 and the lower water pan 1106 are hollow inside for concentrating / dispersing ballast water. The bottom of the lower water pan 1106 is connected to a second connecting pipe 15. The second connecting pipe 15 is internally equipped with... Equipped with a coarse filter cartridge 17, which is mainly used to filter larger impurities in ballast water, and a third connecting pipe 19 is connected to the side of the second connecting pipe 15. A second check valve 20 for connecting to the outlet pipe is connected to the side of the third connecting pipe 19. The first check valve 10 and the second check valve 20 can be set as electromagnetic check valves. Worm gears 1103 are connected to the sides of multiple butterfly valves 1102. Multiple worm gears 1104 are rotatably connected to the side of the upper water plate 1101. Adjusting the worm gears The rotation of 1104 drives the worm gear 1103 to rotate, thereby adjusting the opening / closing of the butterfly valve 1102. Multiple sets of worm gears 1104 mesh with multiple sets of worm gears 1103 respectively, and each end of the multiple sets of worm gears 1104 is provided with a first friction disc 1105. The side of the water plate 1101 is provided with multiple sets of adjustment mechanisms 12 for adjusting the rotation of the first friction disc 1105. The adjustment mechanism 12 can simultaneously adjust the state of two adjacent butterfly valves 1102.

[0048] Please refer to the above embodiments for further details. Figure 2 The bidirectional axial flow pump 1 includes a pump pipe 101, and a pump body impeller 102 is rotatably connected inside the pump pipe 101. A drive device 103 for driving the pump body impeller 102 to rotate is installed on the top of the pump pipe 101. The anti-clogging and purification system also includes a first connecting pipe 6, which is used to connect the pump pipe 101 and the movable pipe 7. By setting the bidirectional axial flow pump 1, bidirectional adjustment of the ship's anti-roll system can be realized. Compared with the unidirectional axial flow pump, it is not only easier to adjust, but also reduces the space occupied by the equipment.

[0049] In the above embodiments, please refer to the specific examples. Figure 1Both ends of the bidirectional axial flow pump 1 are equipped with anti-clogging and purification systems. One set of anti-clogging and purification systems is connected to a set of ship ballast water tanks via a second inlet pipe 4, a first outlet pipe 3, and the other set of anti-clogging and purification systems is connected to another set of ship ballast water tanks via a first inlet pipe 2, a second outlet pipe 5, and the same system. When the bidirectional axial flow pump 1 operates in the forward direction, ballast water enters through the second inlet pipe 4 and exits through the second outlet pipe 5. When the bidirectional axial flow pump 1 operates in the reverse direction, ballast water enters through the first inlet pipe 2 and exits through the first outlet pipe 3. By setting up the anti-clogging and purification system, impurities in the ballast water can be filtered and collected, thereby purifying the ballast water and reducing the damage of impurities to the pump equipment.

[0050] Please refer to the above embodiments for further details. Figure 16 The second connecting pipe 15 has a conical cylinder 16 installed inside, which extends into the coarse filter cylinder 17. The bottom of the second connecting pipe 15 is threaded with a plug 18, which is used to seal the coarse filter cylinder 17. By setting the conical cylinder 16, ballast water can be discharged into the coarse filter cylinder 17. The coarse filter cylinder 17 has a certain length, which allows some larger impurities to accumulate inside the coarse filter cylinder 17.

[0051] Please refer to the above embodiments for further details. Figure 12 - Figure 14 The flocculent filter assembly 13 includes a sleeve 1301, and multiple sets of drive impellers 1302 are rotatably connected inside the sleeve 1301. The multiple sets of drive impellers 1302 are arranged in three layers from top to bottom. The first layer has a set of drive impellers 1302 in the middle position, and the bottom of the first set of drive impellers 1302 is provided with long nylon packing 1304. The second and third layers each have four sets of drive impellers 1302, and the drive impellers 1302 in the second and third layers are staggered. The bottom of the drive impellers 1302 in the second and third layers is provided with short nylon packing 1303 and long nylon packing 1304. The length of 1304 covers the length of the space where the second and third layer drive impellers 1302 are located. A flocculent filter assembly 13 is set up to filter and remove flocculent sediments in the ballast water. The flocculent filter assembly 13 is mainly composed of short nylon packing 1303 and long nylon packing 1304. The long nylon packing 1304 is located in the middle, and two layers of short nylon packing 1303 are evenly distributed around the long nylon packing 1304. The two layers of short nylon packing 1303 are staggered. This can ensure the flow of ballast water and make the packing evenly distributed to filter and adsorb flocculent impurities in the ballast water.

[0052] In the above embodiments, please refer to the specific examples. Figures 6-11The adjusting mechanism 12 includes a housing 1201. Inside the housing 1201 are two sets of first supports 1202, which are vertically distributed. Each set of first supports 1202 has a first bevel gear 1203 rotatably connected to its side. Inside the housing 1201, two sets of second supports 1205 are also movably mounted via a limiting component 1204. These second supports 1205 are also vertically distributed and correspond to the two sets of first supports 1202. Each set of second supports 1205 has a first square drive shaft 1206 rotatably connected to its side, and the two sets of first square drive shafts 1206 movably pass through the two sets of first bevel gears 1203. Furthermore, each of the two sets of first square drive shafts 1206 is provided with a second friction disc 1207 at its end. A first spring 1208 is provided between the second friction disc 1207 and the corresponding first bevel gear 1203. By setting the adjustment mechanism 12, the opening and closing states of the two sets of butterfly valves 1102 can be adjusted simultaneously. When one set of butterfly valves 1102 goes from open to closed, the adjacent butterfly valve 1102 will go from closed to open. In this way, the switching of the flocculent filter assembly 13 can be carried out without stopping the equipment. The second friction disc 1207 is set to move and actively fit against the first friction disc 1105, thereby realizing that the adjustment mechanism 12 simultaneously drives the two sets of butterfly valves 1102 to open / close.

[0053] Please refer to the above embodiments for further details. Figures 6-11 The housing 1201 has two sets of first spur gears 1209 rotatably connected inside. Each set of first spur gears 1209 has a second bevel gear 1210 at its bottom. The two sets of second bevel gears 1210 mesh with the two sets of first bevel gears 1203 respectively. The housing 1201 also has a second square drive shaft 1215 inside. A second spring 1216 is sleeved on the outside of the second square drive shaft 1215, and a linkage block 1217 for pressing the second support 1205 is movably mounted on the outside of the second square drive shaft 1215. The internal part is provided with a guide rod 1218, and a third spring 1219 is sleeved on the outside of the guide rod 1218. A pressing block 1220 for pressing the linkage block 1217 is movably installed on the outside of the guide rod 1218. By setting the linkage block 1217 and the pressing block 1220, the pressing block 1220 can push the linkage block 1217 to move when the height of the pressing block 1220 is adjusted. In turn, the movement of the linkage block 1217 can push the two sets of second brackets 1205 to move, thereby realizing that the second bracket 1205 drives the second friction disc 1207 to actively conform to the first friction disc 1105.

[0054] Please refer to the above embodiments for further details. Figures 6-11Inside the housing 1201, a second spur gear 1211 is rotatably connected between two sets of first spur gears 1209. The second spur gear 1211 meshes with the two sets of first spur gears 1209, and a limiting groove 1212 is provided inside the second spur gear 1211. A sleeve 1213 is rotatably connected to the top of the second spur gear 1211. Two sets of fitting grooves 1214 are symmetrically provided on the side of the sleeve 1213. By setting the second spur gear 1211 and the sleeve 1213, the second friction disc 1207 is driven to rotate, thereby driving the first friction disc 1105 to rotate. The sleeve 1213 and the second spur gear 1211 are rotatably connected. Thus, when the operator installs the throttle 14, the sleeve 1213 can be rotated so that the fitting groove 1214 on its side actively aligns with the spring pin 21 of the throttle 14, making the installation of the throttle 14 more convenient. The installation of the throttle 14 can be achieved by using the throttle 14 to push the extrusion block 1220 down.

[0055] Please refer to the above embodiments for further details. Figures 6-11 The second spur gear 1211 has a rotating handle 14 installed inside. The rotating handle 14 is used to press the pressing block 1220. The rotating handle 14 matches the limiting groove 1212. Two sets of spring pins 21 are symmetrically arranged on the side of the rotating handle 14 and are installed by springs. The spring pins 21 match the fitting groove 1214 on the side of the sleeve 1213. By setting the rotating handle 14, the second friction disk 1207 of the adjusting mechanism 12 can actively engage the first friction disk 1105 by the pressing insertion of the rotating handle 14. Then, the rotation of the rotating handle 14 can make the second friction disk 1207 rotate and drive the first friction disk 1105 to rotate.

[0056] In practical operation, from the perspective of the continuous operation of the ship's anti-heeling system, for example, when ballast water from the right-side ballast tank is input into the left-side ballast tank, the ship's control system activates the drive device 103 to rotate the pump impeller 102. The rotation of the pump impeller 102 generates negative pressure to draw in the ballast water. At this time, due to the restriction of the second one-way valve 20, the ballast water cannot enter the third connecting pipe 19 of the right-side anti-clogging purification system. Therefore, the ballast water in the right-side ballast tank enters the first one-way valve 10 of the right-side anti-clogging purification system through the second inlet pipe 4. The ballast water in the first one-way valve 10 enters the movable pipe 7 through the three-way pipe 9, and then the ballast water passes through... The filtration of the inlet filter screen 8 enters the pump pipe 101 through the first connecting pipe 6 of the right anti-clogging purification system. Then, the ballast water flowing in the pump pipe 101 enters the first connecting pipe 6 of the left anti-clogging purification system. The ballast water can backwash the inlet filter screen 8 of the left anti-clogging purification system. Similarly, the two anti-clogging purification systems will flush each other during continuous operation, so that the ballast water flows through the bidirectional axial flow pump 1 after being filtered by the inlet filter screen 8. This reduces the damage of impurities in the ballast water to the bidirectional axial flow pump 1. Moreover, the repeated backwashing of the inlet filter screen 8 during continuous operation can maintain the filtration effect of the inlet filter screen 8.

[0057] When the ballast water drawn from the pump pipe 101 enters the left-side anti-clogging purification system, it first backwashes the inlet filter screen 8. Then, due to the restriction of the first one-way valve 10, the ballast water enters the upper water pan 1101 through the three-way pipe 9. The ballast water then enters the flocculent filter assembly 13 through the open butterfly valve 1102. The flowing ballast water drives multiple sets of drive impellers 1302 to rotate slowly, thereby driving multiple sets of short nylon packing 1303 and long nylon packing 1304 to rotate. The multiple sets of short nylon packing 1303 and long nylon packing 1304 are evenly and alternately distributed, ensuring the flow of ballast water while allowing larger impurities to pass through, thus allowing the short nylon packing 1303 to pass through. The 303 and long nylon packing 1304 can actively wrap around and adsorb flocculent impurities in the ballast water. The ballast water that has passed through the flocculent impurities then enters the second connecting pipe 15 through the drain pan 1106. The ballast water then enters the coarse filter cylinder 17 through the conical cylinder 16. The coarse filter cylinder 17 has a certain height and can filter and collect larger impurities in the ballast water. Since the content of larger impurities in the ballast water is relatively small, the staff can periodically loosen the plug 18 to remove the coarse filter cylinder 17 for cleaning. Subsequently, the ballast water enters the third connecting pipe 19 of the left anti-clogging purification system and is then discharged from the second one-way valve 20 to the second outlet pipe 5, allowing the ballast water to enter the left ballast water tank.

[0058] Due to the long-term use of ballast water, there is usually a large amount of flocculent sediment. Therefore, multiple sets of flocculent filter components 13 are installed and used alternately. One set of butterfly valves 1102 is in the open state. When the flocculent filter component 13 below the butterfly valve 1102 needs to be removed and replaced, the operator uses the handle 14 to insert it into the sleeve 1213 and into the limiting groove 1212 of the second spur gear 1211. The angle of the sleeve 1213 is manually adjusted so that the fitting groove 1214 on its side and the side of the handle 14 are aligned. Align the spring pins 21, then press the two sets of spring pins 21 to retract them into the inside of the throttle 14. Finally, continue to press the throttle 14 to lower the height of the throttle 14 and squeeze the compression block 1220. The compression block 1220 will slide along the guide rod 1218 and compress the third spring 1219. When the compression block 1220 drops to the specified height, the spring pins 21 on the side of the throttle 14 are just fitted into the fitting groove 1214 on the side of the sleeve 1213. The fitting groove 1214 limits the spring pins 21, thereby preventing the throttle 14 from being pulled out.

[0059] When the pressing block 1220 descends, it presses the linkage block 1217, causing the linkage block 1217 to slide along the second square drive shaft 1215 and compress the second spring 1216. The sliding of the linkage block 1217 along the second square drive shaft 1215 will press the two sets of second brackets 1205, causing the two sets of second brackets 1205 to slide along the limiting components 1204 at their respective bottoms. In turn, the second brackets 1205 push the first square drive shaft 1206 to slide within the first bevel gear 1203, and the first square drive shaft 1206 drives the second friction disc 1207 connected to it to move, so that the second friction disc 1207 fits against the first friction disc 1105. When the second friction disc 1207 moves, it will stretch the first spring 1208. That is to say, when the operator presses down the installation throttle 14, the two sets of second friction discs 1207 of the adjustment mechanism 12 can fit against the adjacent first friction disc 1105.

[0060] Next, the operator turns the handle 14, which drives the second spur gear 1211 to rotate through the limit groove 1212. The second spur gear 1211 drives the two sets of first spur gears 1209 to rotate. The first spur gears 1209 drive the connected second bevel gear 1210 to rotate. Then, the second bevel gear 1210 drives the meshing first bevel gear 1203 to rotate. The first bevel gear 1203 drives the first square drive shaft 1206 to rotate. Then, the first square drive shaft 1206 drives the first friction disc 1105 to rotate through the second friction disc 1207 at its end. The first friction disc 1105 drives the worm gear 1104 to rotate. The worm gear 1104 drives the worm wheel 1103 to rotate. As a result, the butterfly valve 1102 in the open state and the butterfly valve 1102 in the adjacent closed state will close / open simultaneously, so that the equipment can switch the flocculent filter component 13 without stopping the machine.

[0061] After all three sets of flocculent filter components 13 have been used, they can be removed and replaced together, which can reduce the workload of staff.
