Technical Field
[0001] The utility model belongs to the technical field of electroplating automatic line cleaning production, in particular to an electroplating automatic line wind curtain type wind cover. Background Art
[0002] Nowadays, the original ventilation hood of the electroplating automatic line is extremely inefficient, and the exhaust gas is mixed with most of the harmless gases in the workshop. As the country's requirements for electroplating emission standards become increasingly stringent, the requirements for exhaust volume and concentration are getting higher and higher. We have conducted in-depth exploration and research on this issue.
[0003] In the previous wind hoods, the more conventional technology is to set up double-sided exhaust hoods on the sides of the electroplating tank. The internal structure adopts a variable cross-section method to ensure uniform air volume, and several air suction slits are opened in the length direction of the exhaust hood. This method cannot ensure that most of the exhaust gas is discharged because the air suction port of the wind hood is still a certain distance away from the liquid surface of the solution; and as the width of the electroplating tank increases, the exhaust gas in the middle of the tank cannot be discharged in time. The hardware configuration of this method is relatively complex, and the power consumption caused by it will be relatively much larger, but the effect is not obvious. There are certain defects, which will cause the exhaust gas to escape into the working environment and harm the environment.
[0004] In order to solve the current situation that the above-mentioned deficiencies of exhaust hoods affect the quality of workshop environment, our company has specially launched the latest developed air curtain hood. The hood can form negative pressure in the air in the tank and positive pressure in the air above the tank, ensuring that most of the waste gas can be discharged through the air curtain hood during the process of placing, lifting and transporting electroplated parts. This can not only effectively prevent the waste gas from polluting the workshop space, but also ensure the air supply or exhaust efficiency of the workshop and reduce the emission of waste gas.

The guide plate 115 is arranged on one side of the cover body 111. The guide plate 115 and the cover body 111 are an integrated structure, and the guide plate 115 extends into the electroplating tank 3. The air inlet 112 is arranged on the outer wall of the cover body 111, and the plurality of air inlets 112 are evenly arranged along the length direction of the cover body 111, and the air inlet 112 is located on the inner side of the guide plate 115, and the air outlet 113 is arranged on the outer wall of the cover body 111, and the air outlet 113 is communicated with the suction fan 12, and the groove 114 is arranged on the outer wall of the cover body 111, and the air supply pipe 13 is located in the groove, and one end of the air supply pipe 13 is fixedly connected to the outer wall of the groove 114, and the other end is connected to the first blower 14, and the guide plate 115 is used to guide the airflow to help the exhaust gas enter the cover body 111 from the air inlet 112.
[0029] The suction fan 12 includes a vacuum generator 121 and a second blower. The vacuum generator 121 is located in the cover body 111.

At this time, the first blower 14 sends out air through the air supply pipe 13, and the second blower sucks air into the hood body 111 through the vacuum generator 121. In this process, the air flow flows from the air supply pipe 13 to one side of the electroplating part suspension plate 4, and then flows through the side of the electroplating part suspension plate 4, and then flows through the solution surface in the electroplating tank 4 to take away the generated waste gas. Then it flows into the air inlet 112 through the guide plate 115 to reach the cover body 111, and then passes through the vacuum generator 121 and flows out of the air outlet 113. At this time, the air outlet 113 is connected to the exhaust gas collection and treatment device. In this process, due to the influence of the airflow, the exhaust gas generated in the electroplating tank 3 will not be directly dispersed into the air, but will be all brought into the cover body 111 by the airflow. When the electroplating tank 3 is too wide, adjust the frequency converter to increase the power of air supply and suction of the utility model to achieve the ideal operating effect of the utility model.
