Description

Technical Field

[0002] The traditional name for coatings in China is paint. The so-called coating is applied to the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the coated object. It is usually a viscous liquid based on resin, oil, or emulsion, with or without pigments, fillers, and corresponding additives, prepared with organic solvents or water. Coatings are organic chemical polymer materials, and the coating film formed belongs to the type of polymer compounds. According to the classification of modern chemical products, coatings are fine chemical products. During transportation, coatings need to be stored in storage tanks.

[0003] However, when the existing paint transport storage tank is in use, the pouring port of the storage tank is usually sealed with a sealing plug. After long-term use, the sealing plug is prone to wear and oxidation, which affects its sealing effect. At the same time, impurities are easily adhered to the surface of the sealing plug, which also affects its sealing performance, increases the contact between the paint and moisture or oxygen in the air, and accelerates the volatilization of solvents and water, causing the paint to easily solidify.

After the airbag is inflated, the sealing plate abuts against the first inclined surface and slides downward along its surface, thereby pushing the second sealing block to move in the direction close to the connecting plate. At the same time, the first spring is compressed, and the connecting rod is rotated, thereby pushing the first sealing block to move upward along the guide rail, so that the first sealing block seals the first inflation hole. At the same time, the second sealing block is staggered from the second inflation hole.

[0032] Working principle: When the paint needs to be transported, the paint is injected into the storage tank body 1 through the pouring port 101 for storage. After the injection is completed, the rocker 1005 is rotated. The rotation of the rocker 1005 drives the rotation of the threaded rod 1004, thereby driving the movable plate 11 to move downward, and driving the sealing plug 102 to move downward through the telescopic mechanism 7. In addition, the gas storage cylinder 1702 and the piston 1703 are driven to move downward synchronously through the movable plate 11 and the sealing plug 102, so that the sealing plug 102 is inserted into the pouring port 101, and when the sealing plug 102 is aligned with the top of the sealing ring 18, When the movable plate 11 continues to move downward, the distance between the movable plate 11 and the sealing plug 102 gradually decreases.

After the airbag 14 is inflated, the sealing plate 404 abuts against the first inclined surface 401 and slides downward along the surface thereof, thereby pushing the second sealing block 303 to move toward the connecting plate 502. At the same time, the first spring 503 is compressed, and the connecting rod 603 is rotated, thereby pushing the first sealing block 302 to move upward along the guide rail 301, so that the first sealing block 302 blocks and seals the first inflation hole 15. At the same time, the second sealing block 303 is staggered from the second inflation hole 16. At this time, the second sealing block 303 no longer blocks and seals the first inflation hole 16. The second air filling hole 16 is sealed, so that the inert gas can be filled into the pouring port 101 through the second air filling hole 16, and the pressurization operation is performed, which effectively isolates the direct contact between the external air and the coating, prevents high-oxygen and high-dew point air from entering the interior, and reduces the contact between the coating and oxygen, moisture, etc. in the air, thereby delaying the curing process of the coating. At the same time, it can inhibit the volatilization of the solvent and moisture in the coating and prevent the curing of the coating. After the pressurization is completed, the sealing plate 404 abuts against the top of the second air filling hole 16, and the second air filling hole 16 can be blocked and sealed; Furthermore, when the second sealing block 303 moves, the vertical plate 901 is driven to move synchronously. When the vertical plate 901 abuts against the second inclined surface 906, the triangular block 905 and the sliding plate 904 can be pushed to move upward. At the same time, the second spring 910 is compressed. When the vertical plate 901 passes over the triangular block 905, the second inflation hole 16 is opened. At the same time, the sliding plate 904 and the triangular block 905 can move downward under the action of the second spring 910, and the limiting surface 907 abuts against the side wall of the vertical plate 901, so that the vertical plate 901 and the second sealing block 303 can be limited. When it is necessary to inject paint into the storage tank body 1 again, the movable plate 11 is moved upward by the lifting mechanism 10, and the connecting column 403 and the sealing plate 404 can be driven to move upward by the moving rod 402. At the same time, the third spring 703 is gradually reset, and the piston 1703 moves upward and resets along the gas cylinder 1702. At this time, the inert gas in the pouring port 101 can be absorbed through the second inflation hole 16 and returned to the gas cylinder 1702 for storage through the inflation tube 1705. When the connecting column 403 abuts against the pushing block 909, the sliding plate 904 and the triangular block 905 can be pushed to move upward, and the triangular block 905 can be separated from the vertical plate 901. At this time, the second sealing block 303 and the vertical plate 901 can be moved and reset under the action of the first spring 503, and the second inflation hole 16 can be filled with water. 16 is sealed, and at the same time, the first sealing block 302 is driven to move downward by the connecting rod 603. At this time, the first inflation hole 15 is opened. When the piston 1703 continues to move upward along the gas storage cylinder 1702, the inert gas in the installation groove 13 can enter the installation cavity 12 and return to the gas storage cylinder 1702 for storage through the inflation tube 1705, so that the airbag 14 shrinks and resets. At this time, the third spring 703 is completely reset. When the moving plate 11 continues to move upward, it can drive the sealing plug 102 to move upward and open, so as to facilitate the recovery of the inert gas in the storage tank body 1 and the pouring port 101 for reuse. In addition, before the sealing plug 102 is pulled out, the airbag 14 shrinks and resets, so as to avoid the wear of the airbag 14 and ensure its sealing effect and service life; At the same time, when the movable plate 11 drives the sealing plug 102 to move upward, the connecting rod 802 can drive the push rod 803 to slide upward in the sliding groove 801, so as to drive the rotating tube 203 to rotate in the fixing ring 202, thereby driving the bristles 204 to rotate, so as to clean the surface of the sealing plug 102 and the airbag 14. After the cleaning is completed, the pouring port 101 can be sealed and protected by the rotating tube 203; Furthermore, when the sealing plug 102 moves downward, the pushing rod 803 can be driven to move downward in the sliding groove 801 through the connecting rod 802. At this time, the rotating tube 203 and the bristles 204 can also be pushed to rotate, so that the surface of the pouring port 101 and the airbag 14 can be cleaned again, thereby ensuring the sealing effect and service life of the sealing plug 102 and the airbag 14, and effectively preventing the paint from solidifying.
