Description

Technical Field

[0001] This invention relates to the field of rust and paint removal technology for ship bottoms, specifically, to a separation and collection device for rust and paint removal from ship bottoms. Background Technology

[0002] When a ship sails in the ocean, the hull provides a relatively stable environment, free from the disturbance of the marine benthic environment. This makes it easy for barnacles to attach to the hull. The sticky substances secreted by the barnacles can penetrate the paint film and continuously erode the hull coating. Over time, this can cause corrosion of the hull structure, affecting the safety of navigation. Furthermore, it can cause eddies and turbulence when the water flows over the barnacles, increasing the drag and affecting the speed of navigation.

[0003] To remove these barnacles, high-pressure water guns are usually used. However, using high-pressure water guns to remove barnacles from the bottom of the hull can damage the hull's paint, causing rust to grow. Since the rust and rust blocks cannot fall into the water (as this would pollute the environment), the removed rust blocks need to be cleaned up.

[0004] When removing rust from the bottom of a ship, it is usually necessary to first sail the ship to a dry dock. When the ship enters the dry dock for repair, water is first filled into the dock using flood control facilities. Once the water level inside and outside the dock is equal, the dock gate is opened, and the ship is slowly pulled into the dock using towing equipment. After that, the water in the dock is pumped out, allowing the ship to sit on the keel pier. When removing rust from the bottom of the ship, shot blasting or shot peening (or sandblasting) is generally used. During the rust removal process, a large amount of dust is usually generated, which affects the health of the workers. Therefore, the dust is usually treated. First, the dust is separated by a cyclone dust collector. The separated waste comes to the bottom of the dust collector, where the collected dust is concentrated at one end by an auger, and then continuously discharged through a star-shaped ash discharge valve.

[0005] However, the waste entering the bottom of the cyclone dust collector generally includes fibrous old paint, flocculent material or large flaky rust blocks, as well as abrasives. These materials are very easy to get tangled and blocked at the inlet of the auger, the spiral body or the star-shaped ash discharge valve, causing the auger or ash discharge valve to jam and requiring the machine to be stopped for cleaning, thus affecting the collection of waste. Summary of the Invention

[0006] To overcome the above-mentioned defects, embodiments of the present invention provide a separation and collection device for rust and paint removal from ship bottoms, which solves the technical problem in the prior art that waste generated during the rust and paint removal process from ship bottoms is prone to entanglement and blockage at the inlet of the auger, the spiral body, or the star-shaped ash discharge valve, causing the auger or star-shaped ash discharge valve to jam.

The driven helical gear is located inside the support frame. A plurality of driving helical gears are fixedly installed at equal intervals on the transmission shaft. The plurality of driving helical gears correspond one-to-one with the plurality of driven helical gears and mesh with them.

[0011] For example, in a separation and collection device for rust and paint removal from the bottom of a ship provided in at least one embodiment of this disclosure, the unblocking component includes: The unblocking frame is provided inside each of the several crushing tanks. Several connecting frames are fixedly installed on the unblocking frame at equal angles. The connecting frames are fixedly connected to the inner wall of the crushing tank. The dredging frame is located on the upper part of the conical mesh plate; A rotating ring is rotatably installed inside each of the aforementioned unblocking frames; The unblocking section is installed at the bottom of each of the unblocking frames, and is used to apply impact to the conical mesh plate; The transmission unit is installed inside each of the unblocking frames to drive the unblocking unit to move.

[0012] For example, in a separation and collection device for rust and paint removal from the bottom of a ship provided in at least one embodiment of this disclosure, the unblocking section includes: Positioning cylinders: Several positioning cylinders are fixedly installed at equal angles in a circumferential shape at the bottom of each of the aforementioned unblocking frames; The drain cleaning frame is slidably installed inside each of the positioning cylinders, and a spring is fixedly installed between the drain cleaning frame and the positioning cylinder; A buffer block is fixedly installed at the bottom of each of the aforementioned unblocking racks; Also includes: The rotating ring has a through groove. The top of each of the rotating rings is spiral-shaped; An extension rod is fixedly installed on the top of each of the unclogging racks, and the extension rod is slidably engaged with the top of the rotating ring.

[0013] For example, in a separation and collection device for rust and paint removal from the bottom of a ship provided in at least one embodiment of this disclosure, the transmission unit includes: An internal gear ring is coaxially fixedly installed inside each of the rotating rings, and the internal gear ring is rotatably connected to the unblocking frame; The drive gear is rotatably installed inside each of the aforementioned unblocking frames; A connecting rod is rotatably installed at the bottom of each of the unblocking frames.

[0014] For example, in a separation and collection device for rust and paint removal from the bottom of a ship provided in at least one embodiment of this disclosure, the conveying assembly includes: An output cylinder, which is fixedly mounted on the base; A primary auger and a secondary auger, wherein the primary auger is rotatably installed inside the conveying cylinder and the secondary auger is rotatably installed inside the output cylinder; A rotary valve is installed between the output end of the conveying cylinder and the input end of the output cylinder.

[0015] The beneficial effects of this invention are as follows: 1. In this invention, the waste entering the crushing tank falls onto the conical mesh plate. As the crushing blades rotate, the waste that is prone to clogging, such as fibrous old paint, flocculent material, or large flaky rust blocks, can be crushed, thereby reducing the risk of the primary auger, secondary auger, and rotary valve getting stuck.

[0016] 2. In this invention, as the crushing blade rotates, it drives the connecting rod to rotate, which in turn drives the drive gear to rotate. The drive gear drives the internal gear ring to rotate through the intermediate gear, which in turn drives the rotating ring to rotate. Through the spiral end face at the top of the rotating ring, the corresponding extension rod is pushed to move upward along the axis of the rotating ring. At this time, the spring is compressed. As the rotating ring rotates, when the through groove on the rotating ring moves to the lower part of the extension rod, the extension rod disengages from the rotating ring. Under the elastic force of the spring, the unblocking frame is driven to move quickly toward the conical mesh plate. The buffer block at the bottom of the unblocking frame impacts the conical mesh plate, thereby assisting the waste to pass through the conical mesh plate.

[0017] 3. In this invention, by setting up the crushing component, the fibrous old paint, flocculent matter or large flaky rust blocks and other easily clogged waste in the separated waste are crushed, thereby ensuring the continuous and stable operation of the entire device and reducing downtime for maintenance. By setting up the unblocking component, the waste is prevented from clogging the mesh of the conical screen plate, so that the waste can fall quickly. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0022] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product.

[0027] like Figures 1 to 12The diagram illustrates a separation and collection device for rust and paint removal from ship hulls according to an embodiment of the present invention. It includes a base 1, a conveying support 2 fixedly mounted on the base 1, a conveying cylinder 3 fixedly mounted on the conveying support 2, a cyclone separator 5, a crushing tank 6, a crushing assembly, a conical mesh plate 7, a dredging assembly, and a conveying assembly. Several input connectors 4 are fixedly mounted at equal intervals on the upper part of the conveying cylinder 3. Each input connector 4 is equipped with a cyclone separator 5. A crushing tank 6 is fixedly mounted between each input connector 4 and the output end of each cyclone separator 5. Each crushing tank 6 contains a crushing assembly for separating the rust and paint from the cyclone separator 5. Large pieces of waste are crushed. Each crushing tank 6 has a conical mesh plate 7 fixedly installed inside. Crushing blades 8 are rotatably installed on the conical mesh plate 7. The crushing assembly includes a mounting frame 9, a drive shaft 10, a crushing part, and a drive part. Several conical mesh plates 7 are fixedly installed inside several crushing tanks 6. Each crushing tank 6 has a mounting frame 9 fixedly installed inside. The mounting frame 9 is fixedly connected to the bottom of the conical mesh plate 7. Several drive shafts 10 are rotatably installed inside each mounting frame 9. Each mounting frame 9 is equipped with a crushing part for crushing large particles of waste entering the conical mesh plate 7. The drive part is installed on the base 1 to drive the crushing part.

[0028] Specifically, after using a high-pressure water gun to remove barnacles from the bottom of the ship, the paint on the hull is damaged, leading to rust. When treating the rust and damaged paint on the bottom of the ship, shot blasting (or sandblasting) is generally used for cleaning. This cleaning process generates a large amount of dust, which not only pollutes the environment but also harms the health of the operators. Therefore, a separation and collection device is needed to treat the dust and reduce its harmful effects during the operation.

[0029] Before operation, the input end of the negative pressure equipment (usually a negative pressure fan) is connected to the output ends of several cyclone separators 5. Then, the input pipelines are connected to the input ends of the cyclone separators 5. When the rust and paint layers on the bottom of the ship are cleaned by shot blasting, the input pipelines are placed in the corresponding positions to collect the waste (including fibrous old paint, flocculent material, or larger flaky rust blocks and abrasives, etc.). At this time, the negative pressure equipment is turned on, and the waste from the bottom of the ship cleaned by shot blasting is collected into the cyclone separators 5 through the input pipelines at the input ends of the cyclone separators 5. These wastes are separated and recycled. The separated wastes fall to the bottom of the cyclone separators 5. These wastes enter the input connector 4 through the crushing tank 6 until they enter the inside of the conveying cylinder 3.

[0030] Furthermore, when a higher purification efficiency is required, and it is difficult to meet the requirements using general purification methods, several cyclone separators 5 (usually three to four in series) can be used in series. That is, connect the input pipeline to the input end of the first cyclone separator 5, then connect the output end of the first cyclone separator 5 to the input end of the second cyclone separator 5, and so on, until the output end of the penultimate cyclone separator 5 is connected to the input end of the last cyclone separator 5. At this point, connect the input end of the negative pressure equipment to the output end of the last cyclone separator 5, and you can start operation.

[0031] To prevent fibrous old paint, flocculent material, or large flaky rust from getting tangled in the conveying components, thus avoiding frequent shutdowns for cleaning and reduced efficiency, the drive unit is activated. This drive unit rotates several drive shafts 10, which, through the crushing unit, drives the crushing blades 8 to rotate. Waste entering the crushing tank 6 falls onto the conical mesh plate 7. As the crushing blades 8 rotate, they crush easily clogging materials such as fibrous old paint, flocculent material, or large flaky rust. Simultaneously, the rotation of the crushing blades 8 also activates the unblocking component, ensuring the waste can smoothly pass through the conical mesh plate 7 and enter the conveying cylinder 3 through the input connector 4. The conveying component then continuously feeds the waste into the collection stage for collection.

[0032] like Figures 4 to 7 As shown, in some embodiments and examples, the crushing assembly further includes a crushing section, including a first helical gear 11, a second helical gear 12, and a connecting shaft 13. Each mounting bracket 9 has a first helical gear 11 rotatably mounted inside it. The first helical gear 11 is coaxially arranged with the crushing tank 6. One end of each drive shaft 10 is fixedly mounted with a second helical gear 12. Several second helical gears 12 correspond one-to-one with several first helical gears 11 and mesh with each first helical gear 11. A connecting shaft 13 is fixedly mounted on each first helical gear 11. The connecting shaft 13 is rotatably connected to the mounting bracket 9, and the top of the connecting shaft 13 is fixedly connected to the crushing blade 8.

[0033] Specifically, as the drive shaft 10 rotates, the drive shaft 10 drives the second helical gear 12 to rotate, which in turn drives the first helical gear 11 to rotate. As the first helical gear 11 rotates, it drives the corresponding connecting shaft 13 to rotate, which in turn drives the corresponding crusher 8 to rotate.

[0034] like Figure 4As shown, in some embodiments and examples, the crushing assembly further includes a drive unit, including a support frame 14, a first motor 16, a driven helical gear 17, and a driving helical gear 18. The support frame 14 is fixedly mounted on the base 1, and a transmission shaft 15 is rotatably mounted inside the support frame 14. Several drive shafts 10 are rotatably connected to the support frame 14. The first motor 16 is fixedly mounted on the support frame 14, and the output end of the first motor 16 is fixedly connected to the transmission shaft 15. A driven helical gear 17 is fixedly mounted at the end of several drive shafts 10 away from the second helical gear 12. The driven helical gear 17 is located inside the support frame 14. Several driving helical gears 18 are fixedly mounted at equal intervals on the transmission shaft 15. The several driving helical gears 18 correspond one-to-one with the several driven helical gears 17 and mesh with each other.

[0035] Specifically, when it is necessary to crush the waste entering the crushing tank 6, the first motor 16 is turned on. The first motor 16 synchronously drives multiple active helical gears 18 to rotate, thereby driving several driven helical gears 17 to rotate. Through the rotation of the driven helical gears 17, the corresponding drive shaft 10 can be driven to rotate.

[0036] In some examples, such as Figures 8 to 11 As shown, the unblocking component is installed inside the crushing component to assist in the discharge of small and large particles of waste after crushing. The unblocking component includes an unblocking frame 19, a rotating ring 21, an unblocking part, and a transmission part. Several crushing tanks 6 are equipped with unblocking frames 19. Several connecting frames 20 are fixedly installed at equal angles on the unblocking frame 19. The connecting frames 20 are fixedly connected to the inner wall of the crushing tank 6. The unblocking frame 19 is located on the upper part of the conical mesh plate 7. A rotating ring 21 is rotatably installed inside each unblocking frame 19. An unblocking part is installed at the bottom of each unblocking frame 19 to apply impact to the conical mesh plate 7. A transmission part is installed inside each unblocking frame 19 to drive the unblocking part to move.

[0037] Specifically, as waste continuously enters the crushing tank 6, to prevent small particles and large crushed particles from clogging the conical screen plate 7, a transmission unit is installed. As the crushing blade 8 rotates, the transmission unit drives the rotating ring 21 to rotate. Through the cooperation of the rotating ring 21 and the unblocking unit, the unblocking unit can be pushed to move along the axis of the rotating ring 21, thus moving away from the conical screen plate 7. When the rotating ring 21 rotates to the designated position, the conveying unit will fall rapidly, thereby causing a certain impact on the conical screen plate 7, thus assisting the waste to pass through the conical screen plate 7 and enter the next stage.

[0038] like Figure 8As shown, the top of the dredging frame 19 is set in a cone shape to facilitate the falling of waste. The waste will enter the cone-shaped mesh plate 7 at the side of the dredging frame 19 and between the two adjacent connecting frames 20, without affecting the falling of the waste.

[0039] like Figure 10 , Figure 11 As shown, in some embodiments and examples, the unblocking assembly further includes an unblocking section, including a positioning cylinder 22, an unblocking frame 23, and a buffer block 25. Each unblocking frame 19 has several positioning cylinders 22 fixedly installed at equal angles in a circumferential shape at its bottom. An unblocking frame 23 is slidably installed inside each positioning cylinder 22. A spring 24 is fixedly installed between the unblocking frame 23 and the positioning cylinder 22. A buffer block 25 is fixedly installed at the bottom of each unblocking frame 23. Each buffer block 25 is preferably made of an elastic material. It also includes a through groove 26 and an extension rod 27. A through groove 26 is opened on each rotating ring 21. The top of each rotating ring 21 is set in a spiral shape. An extension rod 27 is fixedly installed on the top of each unblocking frame 23. The extension rod 27 slides with the top of the rotating ring 21.

[0040] Specifically, rotating ring 21, as Figure 9 Rotating in the direction indicated by the arrow, as the rotating ring 21 rotates, the corresponding extension rod 27 is pushed upward along the axis of the rotating ring 21 through the spiral end face at the top of the rotating ring 21. At this time, the extension rod 27 slides relative to the rotating ring 21, and the spring 24 is compressed. As the rotating ring 21 rotates, until the position of the through groove 26 on the rotating ring 21 moves to the lower part of the extension rod 27, the extension rod 27 disengages from the rotating ring 21, and the spring 24 releases pressure. Thus, under the elastic force of the spring 24, the unblocking frame 23 is driven to move quickly toward the conical mesh plate 7. The buffer block 25 at the bottom of the unblocking frame 23 impacts the conical mesh plate 7, thereby assisting the waste to pass through the conical mesh plate 7.

[0041] like Figure 8 , Figure 10 As shown, in some embodiments and examples, the unblocking assembly further includes a transmission unit, including an internal gear ring 28, a drive gear 29, a connecting rod 30, and an intermediate gear 31. An internal gear ring 28 is coaxially fixedly installed inside each rotating ring 21. The internal gear ring 28 is rotatably connected to the unblocking frame 19. A drive gear 29 is rotatably installed inside each unblocking frame 19. A connecting rod 30 is rotatably installed at the bottom of each unblocking frame 19. The top end of the connecting rod 30 is fixedly connected to the drive gear 29, and the bottom end of the connecting rod 30 is fixedly connected to the breaker blade 8. An intermediate gear 31 is rotatably installed inside each unblocking frame 19. The intermediate gear 31 meshes with the internal gear ring 28 and the drive gear 29 respectively.

[0042] Specifically, as the crusher 8 rotates, the crusher 8 drives the connecting rod 30 to rotate, which in turn drives the drive gear 29 to rotate. The drive gear 29 drives the internal gear ring 28 to rotate through the intermediate gear 31, which in turn drives the rotating ring 21 to rotate.

[0043] In some examples, such as Figure 12 As shown, the conveying assembly is installed inside the conveying cylinder 3 to transport waste to the next stage. The conveying assembly includes an output cylinder 32, a primary auger 33, a secondary auger 34, and a rotary valve 35. The output cylinder 32 is fixedly installed on the base 1. The primary auger 33 is rotatably installed inside the conveying cylinder 3. The secondary auger 34 is rotatably installed inside the output cylinder 32. A rotary valve 35 is installed between the output end of the conveying cylinder 3 and the input end of the output cylinder 32. The assembly also includes a second motor 36 and a transmission component 37. The second motor 36 is fixedly installed on the output cylinder 32 and on the conveying support 2. The output end of one second motor 36 is connected to the primary auger 33 via the transmission component 37, and the output end of the other second motor 36 is connected to the secondary auger 34.

[0044] Specifically, after the separated waste passes through the conical mesh plate 7 and finally enters the input connector 4, the waste enters the conveying cylinder 3. At this time, the corresponding second motor 36 is turned on, and through the setting of the transmission component 37, the first-stage auger 33 is driven to rotate, thereby concentrating the collected dust at one end. Then, the star-shaped ash discharge valve 35 is opened to achieve continuous dust discharge while ensuring the internal pressure of the cyclone separator 5, until the waste enters the output cylinder 32. Then, another second motor 36 is turned on, and through the setting of the corresponding transmission component 37, the second-stage auger 34 is driven to rotate, thereby conveying the waste out.

[0045] The working principle or usage process of this application is as follows: When treating the rust and damaged paint on the bottom of a ship, shot blasting is generally used for cleaning. This process generates a large amount of dust, which needs to be treated. Before operation, the input end of the negative pressure equipment (usually a negative pressure fan) is connected to the output end of several cyclone separators 5. Then, the input pipeline is connected to the input end of each cyclone separator 5. When cleaning the rust and paint on the bottom of the ship by shot blasting, the input pipeline is placed in the appropriate position to collect the waste (including fibrous old paint, flocculent material, or larger flaky rust pieces and abrasives).

[0046] When collecting these dust particles, the negative pressure equipment is turned on, and the waste from the bottom of the ship that was shot-blasted is collected into the cyclone separator 5 through the input pipeline at the input end of the cyclone separator 5. The waste particles are separated and recycled. The separated waste particles fall into the bottom of the cyclone separator 5. The waste particles enter the input connector 4 through the crushing tank 6 until they enter the inside of the conveying cylinder 3.

[0047] To prevent fibrous old paint, flocculent material, or large flaky rust from getting tangled in the conveying components, which would require frequent shutdowns for cleaning and reduce efficiency, the first motor 16 is activated. The first motor 16 simultaneously drives multiple active helical gears 18, which in turn drive several driven helical gears 17. The rotation of the driven helical gears 17 drives the corresponding drive shaft 10, which in turn drives the second helical gear 12, which in turn drives the first helical gear 11. The rotation of the first helical gear 11 drives the corresponding connecting shaft 13, which in turn drives the corresponding crushing blade 8. Thus, the waste entering the crushing tank 6 falls onto the conical mesh plate 7. With the rotation of the crushing blade 8, easily clogging waste such as fibrous old paint, flocculent material, or large flaky rust is crushed.

[0048] To prevent small and large particles of waste from clogging the conical mesh plate 7, the rotating blade 8 drives the connecting rod 30 to rotate, which in turn drives the drive gear 29 to rotate. The drive gear 29 drives the internal gear ring 28 to rotate via the intermediate gear 31, which in turn drives the rotating ring 21 to rotate. The spiral end face at the top of the rotating ring 21 pushes the corresponding extension rod 27 to move upward along the axis of the rotating ring 21. At this time, the extension rod 27 slides relative to the rotating ring 21, and the spring 24 is compressed. As the rotating ring 21 rotates, when the slot 26 on the rotating ring 21 moves to the lower part of the extension rod 27, the extension rod 27 disengages from the rotating ring 21, and the spring 24 releases its pressure. Under the elastic force of the spring 24, the unblocking frame 23 is driven to move quickly toward the conical mesh plate 7. The buffer block 25 at the bottom of the unblocking frame 23 impacts the conical mesh plate 7, thereby assisting the waste to pass through the conical mesh plate 7.

[0049] After the separated waste passes through the conical mesh plate 7 and finally enters the input connector 4, it enters the conveying cylinder 3. At this time, the corresponding second motor 36 is turned on, and through the transmission component 37, the first-stage auger 33 is driven to rotate, thereby concentrating the collected dust at one end. Then, the star-shaped ash discharge valve 35 is opened to continuously discharge dust while maintaining the internal pressure of the cyclone separator 5, until the waste enters the output cylinder 32. Then, another second motor 36 is turned on, and through the corresponding transmission component 37, the second-stage auger 34 is driven to rotate, thereby conveying the waste out and collecting it.
