[0002] After the production of metal products, the metal substrate needs to be painted for protection to prevent the metal substrate from being exposed to the air for a long time and being oxidized by the air, which will affect the strength of the metal products. Before painting the metal substrate, the metal surface will be pre-treated to improve the corrosion resistance of the metal substrate and the painting effect.

[0003] Existing metal substrate pretreatment devices generally perform processes such as degreasing, water washing, and film coating on metal substrates. The degreasing process generally involves spraying, brushing, or immersing the metal in the degreasing liquid on the metal surface. When the metal workpiece is transported to the water washing chamber, the bends and reinforcement ribs on the metal workpiece are prone to bring the degreasing liquid into the clean water tank, aggravating the pollution of the clean water tank and having a greater impact on the environment. Therefore, a metal surface atomization closed spray pretreatment device is proposed. Utility Model Content

[0025] like Figure 4 As shown, fog blocking brushes 16 are fixedly installed on both sides of the bottom of the slide rail 4, and the fog blocking brushes 16 are in contact with both sides of the top of the hook 6.

[0026] It should be noted that a water pump is provided at the bottom of the degreasing liquid tank 7, the cleaning liquid tank 8 and the clean water tank 9, the first atomizing nozzle 10, the cleaning nozzle 15 and the second atomizing nozzle 13 are respectively connected to the output ends of the water pumps in the degreasing liquid tank 7, the cleaning liquid tank 8 and the clean water tank 9, and the first mist curtain 11, the cleaning brush 12, the second mist curtain 14 and the mist brush 16 are all made of rubber.

[0027] Working steps: first, inject degreasing liquid into the degreasing liquid tank 7, inject clean water into the cleaning liquid tank 8 and the clean water tank 9, hang the metal substrate workpiece on the hook 6, start the pre-treatment device, start the water pump in the degreasing liquid tank 7, pump the degreasing liquid in the degreasing liquid tank 7 to the first atomizing nozzle 10 for spraying, spray the degreasing liquid on the surface of the metal substrate through the first atomizing nozzle 10, the slider 5 slides in the slide rail 4 to the side of the cleaning chamber 2, and the metal substrate completes the degreasing treatment after passing through the degreasing chamber 1. When the metal substrate passes through the first mist curtain 11, the first mist curtain 11 takes away the degreasing liquid remaining on the surface of the metal substrate and returns to the degreasing liquid tank 7, the slider 5 continues to move, driving the metal substrate to pass through the cleaning brush 12, and the water pump in the cleaning liquid tank 8 is started. The clean water in the cleaning liquid tank 8 is pumped into the cleaning nozzle 15 and sprayed out. The front cleaning brush 12 and the cleaning nozzle 15 flush and clean the surface of the metal substrate. After the metal substrate moves to the rear section of the cleaning brush 12, the rear section of the cleaning brush 12 cleans the surface of the metal substrate to remove the water stains. The clean water in the cleaning chamber 2 returns to the cleaning liquid tank 8, and the metal substrate enters the cleaning chamber 3. The water pump in the clean water tank 9 is started to pump the clean water in the clean water tank 9 into the second atomizing nozzle 13 and spray it out. The second atomizing nozzle 13 cleans the surface of the metal substrate. The clean water returns to the clean water tank 9. When the metal substrate passes through the second mist curtain 14, the second mist curtain 14 cleans the residual water on the metal substrate to complete the pre-treatment of the metal substrate.

[0028] Working principle: A first mist curtain 11 is provided at the connection between the degreasing chamber 1 and the cleaning chamber 2, which can remove a considerable portion of the degreasing liquid, so that the residual degreasing liquid on the metal substrate entering the cleaning chamber 2 and the cleaning chamber 3 is small. The cleaning chamber 2 and the cleaning chamber 3 are provided, which are essentially used to clean the metal substrate and remove the residual degreasing liquid on the surface of the metal substrate. After the metal substrate enters the cleaning chamber 2, the cleaning nozzle 15 cleans the metal substrate, and the cleaning brush 12 brushes it at the same time, which can remove a large amount of residual degreasing liquid. The cleaning brush 12 continues to clean the metal substrate at the rear end, so that the degreasing liquid removed by the cleaning is Most of the liquid remains in the cleaning liquid tank 8. When the metal substrate enters the cleaning chamber 3, the content of the degreasing liquid is very low. After cleaning by the second atomizing nozzle 13, there is basically no degreasing liquid remaining on the metal substrate. The clean water in the clean water tank 9 has a low degree of pollution. The cleaning liquid tank 8 and the clean water tank 9 are separately arranged. The cleaning liquid tank 8 and the clean water tank 9 have different degrees of pollution. The clean water in the clean water tank 9 can continue to be used in the cleaning liquid tank 8 after use to reduce water consumption and reduce pollution. A first atomizing nozzle 10 is arranged on the slide rail 4 to block the splashing degreasing liquid and prevent the degreasing liquid from flowing through the slide rail 4 to further reduce pollution.
