Description

Technical Field

[0001] This utility model relates to the field of electroplating production line and waste gas treatment technology, and in particular to a dual-path air purification electroplating production line. 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 a dual-path air purification electroplating production line with low energy consumption, high waste gas treatment efficiency, and the ability to utilize one maintenance walkway to simultaneously serve two production lines.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a dual-path air-purified electroplating production line, comprising a workshop, two continuous electroplating production lines 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 gradually increasing air intake is provided directly above each electroplating tank. The rear end of the air intake is connected to the air purification device through a pipe. The width of the air intake is greater than or equal to the length of the electroplating tank. A maintenance walkway for workers is provided at the interval between the two continuous electroplating production lines. The two continuous electroplating production lines are symmetrically arranged with respect to the maintenance walkway. The air intake is located on the side of the electroplating tank facing away from the maintenance walkway.

[0009] Preferably, an air quality detector is installed on the side of the continuous electroplating production line. When the air quality is lower than the set value, the air purification device increases the air intake flow of the air inlet. When the air quality is higher than the set value, the air purification device decreases the air intake flow of the air inlet.

[0010] 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.

[0011] 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.

[0012] Preferably, a mounting bracket is provided above the air intake, and the air intake and the pipe are fixed to the mounting bracket.

[0013] The beneficial effects of this utility model are as follows: This utility model provides a dual-path air-purified electroplating production line. In actual production applications, the continuous electroplating production line is used to electroplat the wound 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 airflow dead 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. The structure of the maintenance walkway allows for simultaneous monitoring and maintenance of two electroplating production lines through a single walkway, greatly improving the space utilization rate within the workshop and significantly enhancing cost-effectiveness.

[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, a dual-path air-purified electroplating production line includes a workshop, two continuous electroplating production lines 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. The characteristic feature is that: an air intake vent 3 with a gradually increasing opening is provided directly above each electroplating tank 2, and the rear end of the air intake vent 3 is connected to the air purification device 1 through a pipe 4. The width of the air intake vent 3 is greater than or equal to the length of the electroplating tank 2. A maintenance walkway 5 for workers to pass through is provided at the interval between the two continuous electroplating production lines. The two continuous electroplating production lines are symmetrically arranged with respect to the maintenance walkway 5, and the air intake vent 3 is located on the side of the electroplating tank 2 facing away from the maintenance walkway 5.

[0018] In practical production applications, the continuous electroplating production line is used to electroplat the wound 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 in the entire 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. Efficient and precise capture and collection of pollution at its source achieves "capture first, then treat," significantly reducing the total air volume required for treatment and fundamentally solving the key problems of high energy consumption, high cost, and low efficiency in existing technologies. The structure of the maintenance walkway 5 allows for simultaneous monitoring and maintenance of two electroplating production lines through a single walkway, greatly improving the space utilization rate within the workshop and significantly enhancing cost-effectiveness.

[0019] In this embodiment, an air quality detector is installed beside the continuous electroplating production line, mounted on the inner wall of the air intake 3. When the air quality is lower than a set value, the air purification device 1 increases the airflow rate at the air intake 3; when the air quality is higher than the set value, the air purification device decreases the airflow rate at the air intake 3. While ensuring air quality within the workshop, this further reduces the power consumption of ventilation and air purification equipment, resulting in more significant energy savings and greater practicality.

[0020] 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.

[0021] 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.

[0022] In this embodiment, a mounting bracket is provided above the air intake 3, and the air intake 3 and the pipe 4 are fixed to the mounting bracket, which facilitates the installation and fixation of the air intake 3 and ensures high reliability.
