Description

Technical Field

[0001] This utility model belongs to the field of waste gas circulation and purification technology, and in particular relates to a sealing cover for electroplating tanks for waste gas circulation and purification. Background Technology

[0002] The basic equipment in electroplating systems primarily functions to hold the plating solution. Plating tanks can be arranged in a linear fashion in a manually operated production line, or they can be arranged according to the available space for different plating types. In automated mechanical production lines, they are generally arranged according to the process flow.

[0003] Publication (Announcement) No.: CN222274756U discloses a tank cover structure for an electroplating tank, including two tank covers disposed on the upper end of the tank body, with the two tank covers facing each other. One end of each tank cover is fixedly connected to the output end of an actuator, which is fixedly installed on the tank body. The actuator can drive the tank cover to rotate on the upper end of the tank body, and the two opposing rotating tank covers form an open-close structure with an open upper end of the tank body. The tank cover structure of this utility model, with the tank cover arranged above the tank edge and between the two ventilation hoods, not only ensures sealing, but also ensures that when the tank cover is open, it does not exceed the ventilation hoods on both sides of the tank, thus not increasing the lifting height of the crane. Because it enters the inner side of the ventilation hood, it will be in the position of auxiliary equipment such as the tank width heating pipe, without increasing the tank width. When the tank cover is closed, it can completely seal the tank. This tank cover structure is simple, reliable, and has a fast response speed.

[0004] The problem with the above technology is that when purifying the exhaust gas generated by the electroplating tank, the exhaust pipe is fixed in one place, resulting in a limited absorption range. It cannot evenly absorb and filter the exhaust gas in the sealed cover. Furthermore, the sealed cover cannot be automatically opened and closed, and manual opening and closing can easily waste time. Therefore, we propose an electroplating tank sealed cover for exhaust gas circulation and purification. Utility Model Content

[0016] 1. In this utility model, a rotating rod is rotatably installed on the inner wall of a fixed frame. A hollow plate is installed on the rotating rod and connected to an exhaust pipe. One end of the rotating rod is connected to a motor on the side wall of the fixed frame, and the exhaust pipe is connected to a filter tank through a flexible hose. When the motor rotates, the exhaust pipe on the hollow plate rotates through the rotating rod. Thus, when exhaust gas is sucked from the sealed cover, the motor drives the exhaust pipe to move up and down, thereby adjusting the angle at which the exhaust pipe sucks in exhaust gas. This allows for the suction of exhaust gas from different areas, increasing the suction range. Furthermore, during suction, the electric slide table drives the exhaust gas to be recovered more evenly. A transmission seat is installed on the side wall of the electroplating tank. Threaded rods are rotatably installed at both ends of the square groove inner wall of the transmission seat. One end of the threaded rod is installed on the output shaft of a forward and reverse motor. The threads on the threaded rods are arranged in opposite directions. When the forward and reverse motors rotate, the two sets of threaded sleeves sliding on the threaded rods drive the two sets of sealed covers on the electroplating tank to move simultaneously in opposite directions through the mounting block. This allows the two sets of sealed covers to open and close automatically, saving time. Attached Figure Description

[0023] Please see Figures 1-4This utility model provides a sealing cover for an electroplating tank for waste gas circulation and purification, including a base plate 1. An electroplating tank 3 is movably mounted on the upper surface of the base plate 1. Two sets of sealing cover shells 4 are slidably mounted on the upper surface of the electroplating tank 3. The two sets of sealing cover shells 4 are symmetrically arranged. A transmission assembly 9 is fixedly mounted on the side wall of the electroplating tank 3.

A filter tank 8 is fixedly installed on the fixing plate 6. A flexible hose 11 is fixedly installed on the filter tank 8. One end of the flexible hose 11 is fixedly installed on the side wall of the hollow plate 15. An exhaust fan 7 is fixedly installed on the fixing plate 6. The air inlet of the exhaust fan 7 is connected to the side wall of the filter tank 8, and the air outlet of the exhaust fan 7 is connected to the side wall of the sealing cover 4. An electric slide 12 is fixedly installed on the inner wall of the sealing cover 4. A fixing frame 13 is fixedly installed on the working slide of the electric slide 12. A rotating device is installed on the inner wall of the fixing frame 13. Rotating rod 14, hollow plate 15 is fixedly mounted on the side wall of rotating rod 14, motor 16 is fixedly mounted on the side wall of fixed bracket 13, output shaft of motor 16 is fixedly mounted on one end of rotating rod 14, transmission assembly 9 includes transmission seat 901, threaded rod 902, forward and reverse motor 903, threaded sleeve 904, and mounting block 905. Transmission seat 901 is fixedly mounted on the side wall of electroplating tank 3, and a square groove is opened on transmission seat 901. Threaded rod 902 is rotatably mounted on both ends of the inner wall of square groove. The threads on threaded rod 902 are arranged in opposite directions. The reverse motor 903 is fixedly installed on the side wall of the transmission base 901. The output shaft of the forward and reverse motor 903 is inserted and connected to the transmission base 901. One end of the threaded rod 902 is fixedly installed on the output shaft of the forward and reverse motor 903. The output shaft of the forward and reverse motor 903 and the threaded rod 902 are coaxially connected. Both sets of threaded sleeves 904 are slidably installed at both ends of the threaded rod 902. Both sets of mounting blocks 905 are fixedly installed on the two sets of threaded sleeves 904. The side walls of both sets of sealing covers 4 are fixedly installed on one end of the two sets of mounting blocks 905.

[0024] A rotating rod 14 is rotatably mounted on the inner wall of the fixed frame 13. A hollow plate 15 is mounted on the rotating rod 14 and connected to an exhaust pipe 17. One end of the rotating rod 14 is connected to a motor 16 on the side wall of the fixed frame 13. The exhaust pipe 17 is connected to the filter tank 8 via a flexible hose 11. When the motor 16 rotates, it drives the exhaust pipe 17 on the hollow plate 15 to rotate. Thus, when exhaust gas is drawn from the sealed cover 4, the motor 16 drives the exhaust pipe 17 to move up and down, thereby adjusting the angle at which the exhaust pipe 17 draws in exhaust gas. This allows for the drawing in of exhaust gas from different areas, increasing the absorption range. Furthermore, during the absorption process, the exhaust gas can be recovered more evenly by the drive of the electric slide table 12. The transmission seat 901 is installed on the side wall of the electroplating tank 3. Threaded rods 902 are rotatably installed at both ends of the inner wall of the square groove on the transmission seat 901. One end of the threaded rod 902 is installed on the output shaft of the forward and reverse motor 903. The threads on the threaded rod 902 are arranged in opposite directions. When the forward and reverse motor 903 rotates, the two sets of threaded sleeves 904 sliding on the threaded rod 902 drive the two sets of sealing covers 4 on the electroplating tank 3 to move in opposite directions simultaneously through the mounting block 905. This allows the two sets of sealing covers 4 to open and close automatically, saving time.

[0025] Please see Figure 1 and Figure 4 A filter plate 18 is fixedly installed on the inner wall of the filter tank 8. A condenser 10 is fixedly installed on the inner wall of the filter tank 8. An activated carbon layer 5 is fixedly installed on the inner wall of the filter tank 8. Two sets of guide plates 19 are fixedly installed on the inner wall of the filter tank 8.

A hydraulic rod 2 is fixedly installed on the upper surface of the substrate 1. The lower surface of the electroplating tank 3 is fixedly installed on one end of the hydraulic rod 2.

[0026] The filter plate 18 installed on the inner wall of the filter tank 8 can initially filter large particles in the exhaust gas. Then, the condenser 10 installed on the side wall of the filter tank 8 cools the high-temperature exhaust gas, which can condense acid mist and organic solvents in the exhaust gas. Finally, the activated carbon layer 5 adsorbs the filtered exhaust gas. The filtered exhaust gas is then transported back into the sealed cover 4 for circulation by the exhaust fan 7. The guide plate 19 can divide the interior of the filter tank 8 into layers to prevent the exhaust gas from flowing back.

[0027] The working principle of this utility model:

[0028] In use, a rotating rod 14 is rotatably mounted on the inner wall of the fixed frame 13. A hollow plate 15 is mounted on the rotating rod 14 and connected to the exhaust pipe 17. One end of the rotating rod 14 is connected to a motor 16 on the side wall of the fixed frame 13, and the exhaust pipe 17 is connected to the filter tank 8 through a flexible hose 11. When the motor 16 rotates, the rotating rod 14 drives the exhaust pipe 17 on the hollow plate 15 to rotate. Thus, when exhaust gas is sucked from the sealed cover 4, the motor 16 drives the exhaust pipe 17 to move up and down, thereby adjusting the angle at which the exhaust pipe 17 sucks in exhaust gas. This allows for the suction of exhaust gas from different areas, increasing the suction range. Furthermore, during the absorption process, the exhaust gas can be recovered more evenly by the drive of the electric slide table 12. The transmission seat 901 is installed on the side wall of the electroplating tank 3. Threaded rods 902 are rotatably installed at both ends of the inner wall of the square groove on the transmission seat 901. One end of the threaded rod 902 is installed on the output shaft of the forward and reverse motor 903. The threads on the threaded rod 902 are arranged in opposite directions. When the forward and reverse motor 903 rotates, the two sets of threaded sleeves 904 sliding on the threaded rod 902 drive the two sets of sealing covers 4 on the electroplating tank 3 to move in opposite directions simultaneously through the mounting block 905. This allows the two sets of sealing covers 4 to open and close automatically, saving time.
