Description

Technical Field

[0001] This utility model relates to the field of ship hull coating technology, specifically to a dispensing device with a filtering mechanism for ship hull spraying. Background Technology

[0002] Hull painting is a crucial step in shipbuilding and repair, significantly impacting a ship's corrosion resistance, aesthetics, and navigation performance. It ensures effective protection of the hull in various complex marine environments, reducing maintenance costs and safety hazards caused by corrosion. The formulation of the coating determines its performance, lifespan, and the ship's operational safety and costs.

[0003] Existing ship hull coatings typically require the mixing of multiple raw materials. Some of these materials need to be manually mixed in quantitative steps. The paint has a certain viscosity, making it difficult to squeeze out the measured amount of raw materials, which limits work efficiency. After the paint is mixed, it is not easy to filter it, or a single filtration can only target a specific particle size range, making it difficult to effectively intercept solid impurities in the paint. At the same time, air bubbles are generated during the mixing process, which cannot be filtered or the single filtration has limited effect on removing air bubbles, thus affecting the hull coating effect.

[0024] Please see Figure 1-4As shown, a batching device with a filtering mechanism for ship hull spraying includes a batching tank 1 with a stirring rod inside for mixing. A tank cover 2 is located on top of the batching tank 1. A discharge pipe 3 is fixedly connected to the bottom of the batching tank 1, and the interior of the batching tank 1 communicates with the interior of the discharge pipe 3. When paint falls through the discharge pipe 3, the tank cover 2 can be opened to manually assist the paint in falling, reducing paint residue in the batching tank 1. A batching assembly 4 is located on top of the tank cover 2, including connecting pipes 41 on top of the tank cover 2. Three connecting pipes 41 are installed on the tank cover 2, and the interiors of all three connecting pipes 41 communicate with the interior of the batching tank 1.

An extrusion block 4 is located inside the metering cylinder 42. 3. A control rod 44 is fixedly connected to the top of the extrusion block 43. A positioning block 45 is fixedly connected to one end of the control rod 44. The positioning block 45 drives the control rod 44 to descend, thereby causing the extrusion block 43 to move downward along the inner wall of the metering cylinder 42, so as to facilitate the extrusion of the raw material in the metering cylinder 42 into the mixing tank 1 through the connecting pipe 41. A filter assembly 5 is set at the bottom of the discharge pipe 3. The filter assembly 5 includes a coarse filter cylinder 51 connected to the inside of the discharge pipe 3. A first processing tank 52 is fixedly connected to the outside of the discharge pipe 3. A middle filter cylinder 53 is fixedly connected to the bottom of the inner cavity of the first processing tank 52. The top of the middle filter cylinder 53 is connected and fixed to the part of the coarse filter cylinder 51 without filter holes. A second processing tank 54 is set on one side of the first processing tank 52. A fine filter cylinder 55 is fixedly connected to the bottom of the inner cavity of the second processing tank 54.

[0025] refer to Figure 1 and Figure 2 As shown, a support plate 6 is fixedly connected to the top of the can lid 2, a rack 7 is fixedly connected to the top of the positioning block 45, a connecting rod 8 is rotatably connected to the inner side of the support plate 6, and the connecting rod 8 is supported by the two support plates 6. A gear 9 is meshed with the outer side of the rack 7, and the outer side of the connecting rod 8 is fixedly connected to the inner ring of the gear 9. A motor 10 is provided at one end of the connecting rod 8, and the output end of the motor 10 is fixedly connected to one end of the connecting rod 8. A fixing plate 11 is fixedly connected to the bottom of the motor 10, and one end of the fixing plate 11 is fixedly connected to one side of the support plate 6. A scale window 12 is provided on the outer side of the metering cylinder 42, which facilitates quantitative dispensing and improves the accuracy of the dispensing ratio. The inside of the metering cylinder 42 is connected to a filling pipe 13, which facilitates the injection of three kinds of raw materials into the three metering cylinders 42 respectively through the three filling pipes 13, and can simultaneously perform quantitative dispensing of three kinds of raw materials, thereby improving the dispensing efficiency.

[0026] refer to Figure 1 , Figure 3 and Figure 4As shown, the first processing tank 52 is internally connected to a first conveying pipe 14, which is positioned between the first processing tank 52 and the intermediate filter cylinder 53 to facilitate the conveying of the paint that has undergone two filtrations. A pump body 15 is installed at one end of the first conveying pipe 14, and a second conveying pipe 16 is internally connected to the pump body 15. The interior of the second conveying pipe 16 is connected to the interior of the fine filter cylinder 55. The bottom of the pump body 15 is fixedly connected to the top of the second processing tank 54. A discharge pipe 17 is internally connected to the second processing tank 54, positioned between the second processing tank 52 and the fine filter cylinder 55. Valves are installed at the positions between the filter cartridges 55, connecting pipe 41, discharge pipe 3, and unloading pipe 17 to facilitate control of opening and closing as needed. Support legs 18 are fixedly connected to the outside of the mixing tank 1, and fixing rods 19 are fixedly connected to the outside of the support legs 18. One end of the fixing rods 19 is fixedly connected to the outside of the second processing tank 54. The mixing tank 1 is supported by the four support legs 18, and the first processing tank 52 and the second processing tank 54 are fixed by the four fixing rods 19. The first processing tank 52 and the second processing tank 54 can be opened and disassembled for cleaning.

[0027] Working Principle: During use, three raw materials are conveniently injected into three metering cylinders 42 through three injection pipes 13, and quantitative dispensing is easily achieved with the help of the scale window 12, improving the accuracy of the proportioning. Opening the valve at the connecting pipe 41, driven by the motor 10, causes the connecting rod 8, supported by two support plates 6, to drive the gear 9 to rotate. This causes the gear 9 to drive the rack 7 to descend. With the connection of the positioning block 45, the control rod 44 drives the extrusion block 43 to move downwards along the inner wall of the metering cylinder 42, facilitating the extrusion of the raw materials in the metering cylinder 42 into the mixing tank 1 through the connecting pipe 41. After all three raw materials have fallen into the mixing tank 1, they are stirred and mixed by the rotation of the stirring rod. After mixing, opening the valve at the discharge pipe 3 allows the coating to fall through the discharge pipe 3, opening the tank lid. 2. Artificial assistance is provided to facilitate the falling of the coating, reducing coating residue in the mixing tank 1. The coating falls into the coarse filter cartridge 51, where large impurity particles are intercepted. The coating then flows into the intermediate filter cartridge 53, where medium-sized impurity particles are removed, preparing for fine filtration. The pump body 15 is started, and the coating that has undergone secondary filtration is transported through the first conveying pipe 14 to the second conveying pipe 16, and then injected into the fine filter cartridge 55 through the second conveying pipe 16. This effectively intercepts small particles in the coating, ensuring its cleanliness. The coating is allowed to pass quickly through the coarse filter cartridge 51, which breaks large air bubbles in the coating. The medium and fine filters intercept and break small air bubbles, improving the defoaming effect. The valve at the discharge pipe 17 is opened to facilitate the discharge of the coating that has undergone three filtrations, further improving the mixing effect.
