Description

Technical Field

[0001] This utility model relates to the field of electrolysis technology, and more specifically, to a gas collection hood for an electrolytic cell. Background Technology

[0002] During the electroplating process, the cathode and anode in the electrolytic cell release a certain amount of gas, such as hydrogen and oxygen, when they react with electricity. As these gases escape from the electrolyte surface, they often carry some acid or alkali mist, forming a corrosive and potentially hazardous mixture. If these gases and mist pollutants are released directly into the workshop air without treatment, they may accumulate locally, creating a flammable and explosive environment and posing serious safety hazards. They will also corrode equipment within the workshop and cause long-term adverse effects on the respiratory system and health of operators, severely impacting the safety and hygiene of the working environment.

[0003] To address the aforementioned issues, existing technologies typically involve installing a gas collection hood above the electrolytic cell to collect gases, acid mist, and alkaline mist generated during electroplating. These gases are then guided through a piping system to a waste gas treatment device for purification, thus achieving effective control of pollutants. However, to ensure effective gas collection and prevent leakage, existing gas collection hoods are often fixed and sealed to the top of the electrolytic cell using bolts or other fasteners. While this structure offers advantages in terms of sealing, it has significant drawbacks in practical use: each time workpieces are loaded or unloaded, the bolts must be removed to move the gas collection hood, and then it must be reinstalled and tightened after processing. This frequent disassembly and reassembly not only consumes a significant amount of operating time and significantly reduces the overall efficiency of electroplating production but also causes considerable inconvenience to operators. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes an electrolytic cell gas collection hood to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] An electrolytic cell gas collection hood includes a positioning plate, a sealing plate rotatably connected to one side of the positioning plate via a hinge, a collection hood connected to the surface of the sealing plate, a connecting pipe installed on the top of the collection hood, an exhaust fan connected to the top of the connecting pipe passing through the collection hood, a discharge pipe installed at the output end of the exhaust fan, an electrolytic cell located below the positioning plate, a clamping and unloading mechanism located on the surface of the positioning plate, and a compression sealing mechanism located on the bottom surface of the sealing plate.

[0007] Furthermore, in order to stably clamp the entire gas collecting hood on one side onto the electrolytic cell, the clamping and unloading mechanism includes lifting rods slidably installed on both sides of the positioning plate, a clamping plate connected to the bottom end of the lifting rods, clamping bolts rotatably installed on both sides of the clamping plate, and threaded holes at both ends of the positioning plate, with the clamping bolts engaging with the threaded holes.

[0008] Furthermore, in order to improve the sealing performance between the sealing plate and the electrolytic cell during gas collection, the compression sealing mechanism includes a rubber sealing gasket connected to the bottom surface of the sealing plate. The surface of the rubber sealing gasket has a shrinkage groove, and a number of rubber suction cups are installed inside the shrinkage groove.

[0009] Furthermore, to facilitate the rotation of the collection cover to open and close, a lifting ring is connected to one side of the collection cover.

[0010] Furthermore, in order to increase the friction when the clamping plate and positioning plate are in contact with the top of the electrolytic cell, anti-slip textures are provided on one side of the surface of the positioning plate and clamping plate.

[0011] Furthermore, in order to control the on / off state of the exhaust fan, a control switch is installed on the top of the collection hood.

[0012] Furthermore, in order to observe the reaction within the collection hood and the electrolytic cell, a transparent observation window is installed on one side of the surface of the collection hood.

[0013] The beneficial effects of this utility model are as follows: Through the clamping and unloading mechanism, one end of the sealing plate and the collecting cover can be rotatably installed on one side of the electrolytic cell, realizing the rotational opening and closing of the collecting cover on the electrolytic cell. Through the squeezing sealing mechanism, when the sealing plate and the collecting cover are closed and covering the top of the electrolytic cell, the sealing effect between the sealing plate and the top of the electrolytic cell can be improved, ensuring the overall sealing of the gas collecting cover. At the same time, the collecting cover can be quickly opened and closed every time the electrolytic cell is loaded or unloaded, without the need for cumbersome disassembly and fastening operations using tools, significantly shortening the auxiliary operation time and improving the operating efficiency of the electroplating production line.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] According to an embodiment of the present invention, an electrolytic cell gas collection hood is provided.

[0024] like Figures 1-5As shown, an electrolytic cell gas collection hood according to an embodiment of the present invention includes a positioning plate 1. A sealing plate 2 is rotatably connected to one side of the positioning plate 1 via a hinge. A collection hood 3 is connected to the surface of the sealing plate 2, allowing the gas generated during electrolysis to gather upwards along the collection hood 3. A connecting pipe 4 is installed on the top of the collection hood 3, and an exhaust fan 5 is connected to the top of the connecting pipe 4 through the collection hood 3. An exhaust pipe 6 is installed at the output end of the exhaust fan 5, allowing the gas inside the collection hood 3 to be extracted by the exhaust fan 5 and discharged through the exhaust pipe 6 for unified collection and purification. An electrolytic cell 7 is provided below the positioning plate 1 for electroplating processing inside it. A clamping and unloading mechanism 8 is provided on the surface of the positioning plate 1 for rotatably mounting one end of the positioning plate 1 and the collection hood 3 to one side of the electrolytic cell 7. A compression sealing mechanism 9 is provided on the bottom surface of the sealing plate 2 to ensure a sealing effect between the bottom of the collection hood 3 and the top of the electrolytic cell 7 during gas collection, preventing gas leakage.

[0025] like Figures 1-5 As shown, the clamping and unloading mechanism 8 includes a pair of lifting rods 801 slidably mounted on both sides of the positioning plate 1. The bottom end of the lifting rods 801 is connected to a clamping plate 802. A pair of clamping bolts 803 are rotatably mounted on both sides of the clamping plate 802. A pair of threaded holes 804 are opened at both ends of the positioning plate 1. The clamping bolts 803 cooperate with the threaded holes 804. The top side of the electrolytic cell 7 is placed between the positioning plate 1 and the clamping plate 802. By tightening the clamping bolts 803, the clamping plate 802 moves to one side of the positioning plate 1 and firmly clamps the top side of the electrolytic cell 7, thereby fixing the gas collecting hood to one side of the electrolytic cell 7. After rotating the collecting hood 3, the top opening of the electrolytic cell 7 can be sealed and covered, facilitating gas collection. The compression sealing mechanism 9 includes a rubber sealing gasket 901 connected to the bottom surface of the sealing plate 2. The surface of the rubber sealing gasket 901 has a shrinkage groove 902. The shrinkage groove 902 is installed inside the shrinkage groove. Multiple rubber suction cups 903 cover the top of the electrolytic cell 7 with the gas collection hood. By pressing the sealing plate 2, the rubber sealing gasket 901 is compressed and contracted. The rubber suction cups 903 in the contraction groove 902 can stably adhere to the top edge of the electrolytic cell 7. The rubber sealing gasket 901 can achieve a sealing effect between the sealing plate 2 and the top of the electrolytic cell 7. A lifting ring 10 is connected to one side of the collection hood 3 for easy rotation to open and close the collection hood 3. Anti-slip textures 11 are provided on one side of the surface of the positioning plate 1 and the clamping plate 802 to increase the friction when the clamping plate 802 and the positioning plate 1 are in contact with the top of the electrolytic cell 7. A control switch 12 is installed on the top of the collection hood 3 to control the on / off of the exhaust fan 5. A transparent observation window 13 is installed on one side of the surface of the collection hood 3 to facilitate observation of the reaction inside the collection hood 3.

[0026] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0027] In practical use, one edge of the top of the electrolytic cell 7 is placed between the positioning plate 1 and the clamping plate 802. By manually rotating the clamping bolts 803 on both sides, they engage with the threaded holes 804 on the positioning plate 1, pushing the clamping plate 802 downward along the lifting rod 801, thereby applying clamping force to the top of the electrolytic cell 7 and achieving stable fixation of the gas collecting hood on the side wall of the electrolytic cell 7. Since the positioning plate 1 and the sealing plate 2 are connected by a hinge, the sealing plate 2 can drive the collecting hood 3 above it to rotate around the hinge axis. When it is necessary to load or unload workpieces, the operator can flip the collecting hood 3 upward through the lifting ring 10 to expose the top opening of the electrolytic cell 7 for easy operation; after the workpiece is placed and the electroplating operation is ready to begin, the collecting hood 3 is flipped downward to cover the top of the electrolytic cell 7. During the sealing process, the rubber sealing gasket 901 at the bottom of the sealing plate 2 first contacts the top edge of the electrolytic cell 7. With continued pressure, the rubber sealing gasket 901 undergoes elastic deformation under compression, compressing its internal shrinkage groove 902. Simultaneously, multiple embedded rubber suction cups 903 expel air under pressure, creating a negative pressure adsorption state, firmly adhering to the top surface of the electrolytic cell 7. This achieves an effective seal between the collection hood 3 and the electrolytic cell 7, preventing the leakage of gases generated during electrolysis. After sealing, the exhaust fan 5 is activated via the control switch 12, causing the hydrogen, oxygen, and harmful gases such as acid or alkali mists emitted from the cathode and anode during electrolysis to rapidly gather upwards along the inner cavity of the collection hood 3. These gases then enter the exhaust fan 5 through the connecting pipe 4 and are finally transported to the external waste gas treatment system for centralized purification through the discharge pipe 6, preventing harmful gases from being directly discharged into the workshop environment.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
