Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment for spraying, and in particular to waste gas treatment equipment for a coating production line. Background Art

[0002] The ultra-large structural parts intelligent double-spray environmentally friendly coating line is an industry-leading industrial coating solution, designed to meet the complex coating needs of ultra-large structural parts in the mining machinery industry. It not only meets the co-operation needs of the painting and powder spraying processes of ultra-large structural parts, adapts to workpieces of different shapes and sizes, ensures the flexibility and adaptability of the production process, but also realizes the full automation and intelligence of the production process. At the same time, the application of digital technology realizes real-time monitoring and analysis of production data and improves the efficiency of production management. Green construction is reflected in the selection of spraying solutions and efficient exhaust gas treatment systems, which greatly reduces the impact of the production process on the environment and reflects the commitment to sustainable development and green manufacturing.

[0003] In the current spraying process, the VOCs waste gas treatment process is used to treat the waste gas generated during the spraying process. In the treatment process, generally in the terminal treatment link, a high iodine value activated carbon adsorption and catalytic combustion regeneration process are used to effectively filter and treat the harmful gases in the waste gas. However, in the current treatment process, when the activated carbon adsorption is saturated, it is necessary to stop the machine for activated carbon replacement, followed by desorption, purification and regeneration. As a result, in the waste gas treatment process, when the waste gas treatment equipment is shut down for treatment, the spraying also needs to be shut down. At the same time, some harmful gases will evaporate into the air and affect the environment. It is impossible to replace the activated carbon plate and desorb and regenerate the activated carbon plate without stopping the treatment equipment, resulting in poor waste gas treatment efficiency and treatment effect. At the same time, in the activated carbon filtration process, due to the rapid flow of waste gas, some harmful gases will flow rapidly with the waste gas and cannot be adsorbed and captured by the activated carbon plate, resulting in poor adsorption of harmful substances in the waste gas.

[0042] The air inlet and outlet mechanism comprises: an air inlet ring tube 21 and an air outlet ring tube 22. Both ends of the transmission tube 13 are rotatably connected with a second connecting tube 23 fixedly connected to the filter box 12. A sealing ring block 24 is fixedly connected inside the second connecting tube 23. A sealing rubber ring pad 25 is fixedly connected to one side of the sealing ring block 24. Two air inlet pipes 26 are fixedly connected to the outer surface of the air inlet ring tube 21. One end of the air inlet pipe 26 is slidably connected to the second connecting tube 23. A buffer tube 27 is fixedly connected to the outer surface of the air inlet pipe 26. An electromagnetically controlled flow valve is arranged on the buffer tube 27. A buffer rubber airbag 28 is fixedly connected to one end of the buffer tube 27. An electromagnetically controlled flow valve is arranged on the air inlet pipe 26.

[0043] The first transmission motor 31 drives the bidirectional threaded rod 32 to rotate, the bidirectional threaded rod 32 drives the connecting plate 33 to move, and the connecting plate 33 drives the air intake pipe 21 and the air outlet pipe 22 to move, so that the air intake pipe 26 on the air intake pipe 21 and the air outlet pipe 29 on the air outlet pipe 22 are inserted into the second connecting pipe 23 at both ends of the transmission pipe 13, and the sealing rubber ring gasket 25 on the sealing ring block 24 is squeezed and sealed, and then the air intake pipe 21 is connected with the exhaust gas, and then the exhaust gas enters the filter box 12, and then the activated carbon plate 16 in the filter box 12 is used to adsorb harmful substances in the exhaust gas. At the same time, the second transmission motor 51 drives The transmission shaft 52 rotates, and the transmission shaft 52 drives the third transmission gear 55 to rotate through the first transmission gear 53 and the second transmission gear 54. The third transmission gear 55 drives the transmission pipe 13 to rotate, and the transmission pipe 13 drives the mounting plate 14 and the activated carbon plate 16 on the mounting plate 14 to rotate, and at the same time drives the electric heating disturbance plate 19 to rotate, disturbing the exhaust gas entering the filter box 12, and driving the activated carbon plate 16 to rotate, so that the exhaust gas entering the filter box 12 can better contact with the activated carbon plate 16 for contact adsorption, which greatly improves the adsorption and purification of harmful substances in the exhaust gas, and then enters the outlet through the outlet pipe 29.

At the same time, when the activated carbon plate 16 in the filter box 12 is saturated with adsorption, the electromagnetic valve on the air inlet pipe 26 on the air inlet tube 21 is closed, and then the exhaust gas begins to enter the buffer rubber airbag 28 through the buffer pipe 27.
