Description

Technical Field

[0001] The utility model relates to the technical field of water-based paint processing, in particular to a mixing device used for water-based paint auxiliary agent batching. Background Art

[0002] Water-based paint is harmless to the human body and does not pollute the environment. The paint film is plump, crystal clear, flexible, water-resistant, wear-resistant and easy to use. Water-based paint additives are usually used for mixing during the production process of water-based paint.

[0003] After water-based paint additives are added to water-based paint, they usually need to be stirred and mixed. During the stirring process, air may be introduced into the surface of the water-based paint due to the high-speed movement of the stirrer, causing bubbles to form on the surface of the water-based paint. When bubbles are mixed on the surface of the paint film, holes will be formed after brushing or spraying, affecting the smoothness and appearance of the water-based paint surface. At the same time, bubbles will generate stress in the paint film, resulting in poor mixing effect, causing surface defects in the subsequent drying and curing process, and causing the product quality of the paint to decline.

An exhaust valve 9 is provided between the discharge port 7 and the bubble discharge pipe 8.

[0029] A sealing cover 6 is provided on the top of the mixing tank body 2, and a feed port 10 is provided in the middle of the mixing tank body 2. The feed port 10 passes through the sealing cover 6 and is connected to the interior of the mixing tank body 2. The top of the feed port 10 is connected to a discharge pipe 11;

[0030] A support plate 12 is fixedly connected to the sealing cover 6, and an electric push rod 13 is provided on the side of the support plate 12 close to the feed port 10. The output end of the electric push rod 13 is connected to a weighing plate 14. A rectangular hole is provided on the side wall of the discharge pipe 11. One side of the weighing plate 14 passes through the rectangular hole and extends to the interior of the discharge pipe 11. A pressure sensor is provided at the bottom of the weighing plate 14.

[0031] A driving motor 15 is provided at the bottom of the workbench 1, and an output end of the driving motor 15 is connected to a stirring shaft 16. The end of the stirring shaft 16 passes through the workbench 1 and extends to the interior of the mixing tank 2, and a plurality of stirring blades 17 are fixedly connected to the outer surface.

[0032] A discharge pipe 18 is symmetrically provided at the bottom of the mixing tank body 2 . The discharge pipe 18 is communicated with the interior of the mixing tank body 2 . A solenoid valve is provided at one end of the discharge pipe 18 close to the mixing tank body 2 .

[0033] The side walls of the mixing tank 2 are electrically connected to a vacuum gauge 19 and a pressure safety valve 20 via connecting lines.

[0034] A filter plate 501 is provided inside the air collecting box 5 , and a plurality of ejector pins 502 are fixedly connected to the filter plate 501 .

[0035] In this embodiment, when it is necessary to mix and stir the water-based paint additive ingredients with the water-based paint, the water-based paint additive is first added to the weighing plate 14 of the discharge pipe 11, and the pressure sensor at the bottom weighs the water-based paint additive on the weighing plate 14. After it reaches a certain weight, the electric push rod 13 is started, and the operation of the electric push rod 13 drives the weighing plate 14 to move to the left, so that the discharge pipe 11 and the feed port 10 are in a connected state. At this time, the water-based paint additive on the weighing plate 14 naturally falls from the feed port 10 into the mixing tank body 2 by gravity.

[0036] Specifically, when the water-based paint additive enters the mixing tank body 2 and contacts and mixes with the water-based paint, before starting to stir, first start the vacuum pump 4. When the vacuum pump 4 is running, the gas inside the mixing tank body 2 is extracted, and then the gas enters the gas collecting box 5 through the vacuum pipe 3 and is collected. At the same time, the vacuum state inside the mixing tank body 2 is monitored by the vacuum gauge 19 on one side to ensure that the interior of the mixing tank body 2 can reach the required vacuum degree in advance, promote the interaction between water-based paints, reduce the separation phenomenon between components, and improve the uniformity and stability of the water-based paint mixing.

[0037] When the interior of the mixing tank body 2 reaches a certain vacuum state, the electric push rod 13 is started again to drive the weighing plate 14 to move to the right, closing the feed port 10, and then the drive motor 15 is started. The operation of the drive motor 15 drives the stirring shaft 16 to rotate, and the stirring shaft 16 rotates and drives the stirring blade 17 to rotate, so that when the stirring blade 17 rotates, it can drive the water-based paint additive and the water-based paint solution in the mixing tank body 2 to mix and stir. When bubbles are generated on the surface of the water-based paint during the stirring process, the exhaust valve 9 is started when the bubbles rise. At this time, the bubbles pass through the discharge port 7 and then enter the air collecting box 5 through the bubble discharge pipe 8. When the bubbles enter When it reaches the interior of the air collecting box 5 and passes through the filter plate 501, the ejector pin 502 on its surface punctures the bubbles, so that the solid particles mixed in the bubbles are separated from the bubbles, and the solid particles and impurities are intercepted and precipitated by the filter plate 501, ensuring the uniformity of the water-based paint during the mixing process, reducing the impact of bubbles on the surface of the water-based paint, and ensuring the quality of the product. When the water-based paint is mixed, the solenoid valve is opened, and then the water-based paint inside the mixing tank body 2 can be discharged through the discharge pipe 18. At this time, the pressure safety valve 20 can be used to release the pressure inside the mixing tank body 2, so that the internal state of the mixing tank body 2 returns to normal, so that it can be used normally next time.
