Description

Technical Field

[0001] This utility model relates to the field of electroplating production line and waste gas treatment technology, and in particular to an electroplating production line with air purification. Background Technology

[0002] Electroplating is an important surface treatment process in manufacturing, widely used in industries such as automotive, electronics, and aerospace. However, the electroplating production process inevitably generates a large amount of waste gas pollutants containing various chemical components. These pollutants mainly originate from acid mist, alkaline mist, chromic acid mist, hydrogen cyanide gas, and volatile organic compounds (VOCs) generated in electroplating tanks, stripping tanks, and activation tanks during electrolysis, pickling, and activation processes. These pollutants not only corrode equipment and steel structures in the workshop but also pose a serious threat to the health of operators. Long-term exposure can lead to respiratory diseases, occupational asthma, and other health problems. Furthermore, direct emission without treatment violates increasingly stringent environmental regulations.

[0003] Currently, the most common solution for air pollution in electroplating workshops is overall replacement ventilation. This involves installing a large-scale air supply system at the top of the workshop and a large-scale exhaust system on the side walls or roof, diluting and expelling pollutants through large-scale air replacement throughout the workshop space. While this "large-scale ventilation" model can reduce the concentration of pollutants in the workshop to some extent, its drawbacks are extremely prominent: First, the energy consumption is enormous: electroplating workshops are typically large spaces, requiring a huge volume of fresh air and exhaust air to maintain a certain number of air exchanges. The electrical energy consumed to drive the fans constitutes a significant operating cost. In summer and winter, the energy consumption required to cool or heat the large volume of incoming fresh air is even more staggering, resulting in enormous energy waste.

[0004] Low treatment efficiency and high cost: This method follows the principle of "dilution first, treatment later," diffusing high concentrations of pollutants into the atmosphere throughout the workshop before unified collection and treatment. This results in a huge volume of air that subsequent exhaust gas treatment devices (such as spray towers and purifiers) need to handle, but the initial concentration of pollutants is diluted to a very low level. The investment cost and operating efficiency of the treatment devices (the treatment efficiency for low-concentration, high-volume gases is often not high) are both uneconomical.

[0005] Dead airflow areas exist: The overall ventilation system cannot cover all pollution sources, and dead airflow areas are easily formed near the tank or in the corner of the workshop, causing local accumulation of pollutants, which still endangers the health of employees at the operating station.

[0006] Poor targeting: It is unable to accurately control the source of pollutant emission, which is an "extensive" governance strategy with obvious shortcomings. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide an electroplating production line with air purification that has low energy consumption, high treatment efficiency and significantly reduced airflow dead angle.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an electroplating production line with air purification, including a workshop, a continuous electroplating production line installed in the workshop, and an air purification device. The continuous electroplating production line includes multiple electroplating tanks arranged in a continuous row and an electroplating device installed in each electroplating tank. A suction port with a gradually increasing opening is provided directly above each electroplating tank. The rear end of the suction port is connected to the air purification device through a pipe. The width of the suction port is greater than or equal to the length of the electroplating tank.

[0009] Preferably, the air intake is generally funnel-shaped, and the opening of the air intake is rectangular, with the length of the opening of the rectangle aligned with the midpoint of the length of the opening of the electroplating tank.

[0010] Preferably, a maintenance walkway for workers is provided on the side of the continuous electroplating production line. The maintenance walkway is located on one side of the electroplating tank, and the air intake is located on the other side of the electroplating tank.

[0011] Preferably, a mounting bracket is provided above the air intake, and the air intake and the pipe are fixed to the mounting bracket.

[0012] Preferably, the closer the air intake is to the air purification device, the smaller the inner diameter of the pipe used to connect the air intake.

[0013] The beneficial effects of this utility model are as follows: This utility model provides an electroplating production line with air purification. In actual production applications, the continuous electroplating production line is used to electroplat the coiled electrical terminals. The exhaust gas generated from the electroplating tank is directly sucked in by the air intake and extracted to the air purification device for purification. Since the width of the air intake is greater than or equal to the length of the electroplating tank, it is equivalent to fully covering the opening of the entire electroplating tank, effectively avoiding dead air zones. Because the air intake is designed specifically for the electroplating tank, there is no need to perform overall air exchange for the entire workshop, which reduces the energy consumption of the ventilation equipment and the purification pressure of the air purification device. The air treatment efficiency is high, the energy consumption is low, the cost performance is high, and the practicality is strong. It efficiently and accurately captures and collects pollution from its source, achieving "capture first, then treat," thereby significantly reducing the total air volume that needs to be treated and fundamentally solving the key problems of high energy consumption, high cost, and low efficiency in existing technologies.

[0016] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments. The content mentioned in the embodiments is not intended to limit the present invention.

[0017] like Figures 1 to 2 As shown, an electroplating production line with air purification includes a workshop, a continuous electroplating production line installed in the workshop, and an air purification device 1. The continuous electroplating production line includes multiple electroplating tanks 2 arranged in a continuous row and an electroplating device installed in each electroplating tank 2. A suction port 3 with a gradually increasing opening is provided directly above each electroplating tank 2. The rear end of the suction port 3 is connected to the air purification device 1 through a pipe 4. The width of the suction port 3 is greater than or equal to the length of the electroplating tank 2.

[0018] In practical production applications, continuous electroplating production lines are used to electroplat coiled electrical terminals. Waste gas generated from the electroplating tank 2 is directly drawn into the suction port 3 and extracted to the air purification device 1 for purification. Since the width of the suction port 3 is greater than or equal to the length of the electroplating tank 2, it effectively covers the entire opening of the electroplating tank 2, avoiding dead air zones. Because the suction port 3 is designed specifically for the electroplating tank 2, there is no need for overall air exchange throughout the workshop, reducing both the energy consumption of the ventilation equipment and the purification pressure of the air purification device 1. This results in high air treatment efficiency, low energy consumption, high cost-effectiveness, and strong practicality. By efficiently and accurately capturing and collecting pollution at its source, achieving "capture first, then treat," the total air volume requiring treatment is significantly reduced, fundamentally solving the key problems of high energy consumption, high cost, and low efficiency inherent in existing technologies.

[0019] In this embodiment, the air intake 3 is generally funnel-shaped, and the opening of the air intake 3 is rectangular. The length direction of the opening of the rectangle is aligned with the midpoint of the length direction of the opening of the electroplating tank 2. While ensuring that the air intake 3 is aligned with the opening of the electroplating tank 2, the absorption efficiency and reliability of the exhaust gas can be improved more effectively, making it more practical.

[0020] In this embodiment, a maintenance walkway 5 for workers is provided on the side of the continuous electroplating production line. The maintenance walkway 5 is located on one side of the electroplating tank 2, and the air intake vent 3 is located on the other side of the electroplating tank 2. The maintenance walkway 5 is designed to allow workers to easily observe the production status of the production line at any time.

[0021] In this embodiment, a mounting bracket 6 is provided above the air intake 3, and the air intake 3 and the pipe 4 are fixed to the mounting bracket 6, which facilitates the installation and fixation of the air intake 3 and ensures high reliability.

[0022] In this embodiment, the closer the air intake 3 is to the air purification device 1, the smaller the inner diameter of the pipe 4 used to connect the air intake 3. With this structural design, the air intake 3 that is far away from the air purification device 1 also has a high negative pressure suction force, which effectively balances the air flow and adsorption force of the air intake 3 at different positions, resulting in high reliability and strong practicality.
