Abstract
Description
Technical Field
[0001] This utility model belongs to the field of material surface treatment technology, specifically relating to a micro-arc oxidation electrolytic cell for metal surfaces. Background Technology
[0002] The micro-arc oxidation electrolytic cell is the core equipment in the micro-arc oxidation process of metal surfaces, playing a crucial role in the surface modification of metal materials. Micro-arc oxidation is a technology for in-situ growth of ceramic films on metal surfaces. This process involves complex electrochemical and physicochemical reactions. The electrolytic cell, as a relatively closed and controllable space, can accommodate the electrolyte and the metal workpiece to be treated, providing a stable environment for the micro-arc oxidation reaction. Inside the electrolytic cell, by applying appropriate voltage and current, a micro-arc discharge phenomenon occurs on the surface of the metal workpiece, causing the metal to react with ions in the electrolyte, thereby forming a ceramic film on the metal surface.
[0003] In some existing metal surface micro-arc oxidation electrolytic cells, threaded sealing caps are typically used to seal the drain outlet. After the wastewater is discharged through the sealing cap, it is often difficult to tighten the cap in time, resulting in leakage of some residual waste liquid. The waste liquid in the micro-arc oxidation electrolytic cell often contains heavy metal ions (such as compounds of metals such as aluminum and titanium), acidic and alkaline substances, and various additives. If the leaked waste liquid accidentally comes into contact with human skin, eyes, or other parts of the body, it may cause chemical burns, causing physical pain and harm to personnel. If operators inhale the harmful gases produced by the volatilization of the waste liquid, it may also cause respiratory diseases, poisoning, and other health problems. Utility Model Content

Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

[0027] Example
[0028] Reference Figures 1-5 This is an embodiment of the present invention, which provides a micro-arc oxidation electrolytic cell for metal surfaces, comprising,
[0029] The treatment unit 100 includes an electrolytic cell body 110, an inlet pipe 120 connected above the electrolytic cell body 110, and a drain pipe 130 disposed below the electrolytic cell body 110 for guiding waste liquid to a designated discharge area.
[0030] It should be noted that the electrolytic cell body 110 is the core area of the micro-arc oxidation reaction. It is used to contain the electrolyte and the metal workpiece to be treated, providing a stable spatial environment for micro-arc oxidation. During the micro-arc oxidation process, by applying appropriate voltage and current, a micro-arc discharge phenomenon will occur on the surface of the metal workpiece, which will cause the metal to react with the ions in the electrolyte, thereby forming a ceramic film on the metal surface. The water inlet pipe 120 is used to inject electrolyte into the electrolytic cell body to provide the required liquid medium for the micro-arc oxidation reaction and ensure the continuous progress of the reaction. The drain pipe 130 is used to guide the waste liquid after the reaction in the electrolytic cell to the designated discharge area to complete the discharge of waste liquid.
[0031] The leak prevention mechanism 200 includes a connecting component 210 that is located on the outside of the electrolytic cell body 110, which is capable of preventing waste liquid leakage while connecting the electrolytic cell body 110 and the drain pipe 130.
[0032] And a locking component 220, located outside the connecting component 210, for automatically fixing the position of the connecting component 210 during the discharge of waste liquid through the drain pipe 130.
[0033] Specifically, the connecting component 210 includes a fixed pipe 211 connected to the bottom of the electrolytic cell body 110 and a sleeve 212 disposed at the end of the fixed pipe 211 away from the electrolytic cell body 110 and used to connect the drain pipe 130.
[0034] Furthermore, the connecting component 210 also includes an integrally formed movable plug 213 and a post 214, a first spring 215 fixedly connected to the outer end face of the post 214, and a sealing ring 216 fixedly connected to the other end of the first spring 215.
[0035] It should be noted that the cooperation between the fixed pipe 211 and the sleeve 212 can connect the electrolytic cell body 110 and the drain pipe 130, ensuring that the waste liquid can smoothly enter the drain pipe 130 from the fixed pipe for discharge. During the process of putting the sleeve 212 on the outer surface of the fixed pipe 211, the two movable plugs 213 will squeeze each other and be deep into the inner cavity of the fixed pipe 211 and the sleeve 212 respectively, so as to release the blockage of the fixed pipe 211 and the sleeve 212, so that the waste liquid can flow into the drain pipe 130 through the orifice 214 via the fixed pipe 211 and the sleeve 212.
[0036] First spring 215 and sealing ring 216: The first spring is fixedly connected to the outer end face of the post, and the other end is connected to the sealing ring. When the fixed tube 211 and the sleeve 212 are pressed against each other, the first spring 215 is in a compressed state, which keeps the two movable plugs 213 in a reset tendency at the same time. Thus, after the sleeve 212 is removed, the two movable plugs 213 are automatically driven to seal the fixed tube 211 and the sleeve 212 again.
[0037] Preferably, the drain pipe 130 is fixedly connected to the inner surface of the sleeve 212, and the drain pipe 130 and the sleeve 212 are in communication.
[0038] Two sets of movable plugs 213, orifice pins 214, first springs 215, and sealing rings 216 are provided, and are respectively located in the inner cavities of fixed pipe 211 and sleeve 212. The two sealing rings 216 are respectively fixedly installed on the inner walls of fixed pipe 211 and sleeve 212. The outer surfaces of the two movable plugs 213 slide in contact with the inner walls of fixed pipe 211 and sleeve 212. The two movable plugs 213 are respectively used to seal the ends of fixed pipe 211 and sleeve 212 to prevent waste liquid leakage. The two orifice pins 214 are used to connect fixed pipe 211 and sleeve 212 when the movable plugs 213 release the seal on fixed pipe 211 and sleeve 212.
[0039] It should be noted that the locking component 220 includes a limiting groove 221 distributed in a circumferential array on the surface of the sleeve 212, a ball bearing 222 movably connected to the inner wall of the limiting groove 221, a movable sleeve 223 slidably sleeved on the outer surface of the sleeve 212, and a pressure block 224 integrally formed with the movable sleeve 223 and used to limit the range of motion of the ball bearing 222.
[0040] Furthermore, the locking assembly 220 also includes a second spring 225 sleeved on the outside of the sleeve 212 and used in conjunction with the movable sleeve 223, and a groove 226 formed on the surface of the fixed tube 211 and used in conjunction with the ball bearing 222 to lock the fixed tube 211 and the sleeve 212.
[0041] It should be noted that the ball bearing 222 can roll flexibly within the limiting groove 211. It is used to limit the position of the sleeve 212 and plays a role in positioning and auxiliary locking during connection. When the movable sleeve 223 moves, the pressure block 224 moves accordingly. By moving the movable sleeve 223, the pressure block 224 is driven to a position away from the ball bearing 222, so as to release the limiting of the ball bearing 222 and unlock the connection state of the fixed tube 211 and the sleeve 212. The second spring 225 is used to drive the pressure block to abut. The second spring provides a reset force to the movable sleeve 223 and the pressure block 224, ensuring that they return to their initial positions when no external force is applied. This continuously limits the movement of the ball 222, ensuring the stability of the locking assembly 220. By moving the movable sleeve 223, the pressure block 224 is moved away from the ball 222, and then the sleeve 212 is fitted onto the surface of the fixed tube 211. During this process, the ball 222 moves to the position corresponding to the groove 226. Then, the movable sleeve 223 is released, and the reaction force of the second spring 225 drives the movable sleeve 223 and the pressure block 224 to reset, so that the pressure block 224 squeezes the ball 222 into the groove 226 and restricts the range of motion of the groove 226, thereby locking the fixed tube 211 and the sleeve 212 to prevent them from separating during the waste liquid discharge process, ensuring the sealing and stability of the waste liquid discharge process.
[0042] Specifically, the second spring 225 is fixedly installed on the outer surface of the sleeve 212, and the second spring 225 abuts against the pressure block 224.
[0043] In use, an appropriate amount of electrolyte is injected into the electrolytic cell body 110 through the water inlet pipe 120 to provide the required liquid medium for the micro-arc oxidation reaction. Then, the metal workpiece to be treated is placed into the electrolyte in the electrolytic cell body 110 to ensure that the workpiece is completely submerged and enters the micro-arc oxidation reaction stage. The power is turned on and a suitable voltage and current are applied in the electrolytic cell body 110 to cause micro-arc discharge on the surface of the metal workpiece. The metal reacts with the ions in the electrolyte and gradually forms a ceramic film on the metal surface.
[0044] During this period, the movable plug 213, under the action of the first spring 215 and the sealing ring 216, tightly seals the ends of the fixed pipe 211 and the sleeve 212 to prevent waste liquid leakage.
[0045] Waste liquid discharge stage: First, manually move the movable sleeve 223 to move the pressure block 224 to a position away from the ball 222, release the restriction on the ball 222, so that the ball 222 can move freely in the limiting groove 211. Then, put the sleeve 212 on the outer surface of the fixed pipe 211, so that the two movable plugs 213 squeeze each other and are squeezed into the inner cavity of the fixed pipe 211 and the sleeve 212 respectively, so as to release the blockage of the fixed pipe 211 and the sleeve 212. The fixed pipe 211 and the sleeve 212 are connected through the orifice 214, so that the waste liquid flows into the drain pipe 130 through the fixed pipe 211 and the sleeve 212 and is guided to the designated discharge area.
[0046] Then, the movable sleeve 223 is released, and the reaction force of the second spring 225 drives the movable sleeve 223 and the pressure block 224 to reset, so that the pressure block 224 squeezes the ball 222 into the groove 226 on the surface of the fixed tube 211, locking the fixed tube 211 and the sleeve 212 to prevent them from separating due to the reaction force of the first spring 216 during the waste liquid discharge process;
[0047] After the waste liquid is discharged: Move the movable sleeve 223 again, drive the pressure block 224 to a position away from the ball 222, release the limit on the ball 222, remove the sleeve 212 from the fixed tube 211, and the two movable plugs 213 are simultaneously reset under the action of the first spring 215, re-seal the fixed tube 211 and the sleeve 212 to prevent the leakage of residual waste liquid, and complete the entire micro-arc oxidation process.
[0048] In summary, the leak-proof mechanism 200 not only prevents the leakage of waste liquid from the electrolytic cell body 110 during the micro-arc oxidation reaction, but also seals the electrolytic cell body 110 and the drain pipe 130 during the waste liquid discharge process. After the waste liquid discharge is completed, it quickly seals the electrolytic cell body 110 and the drain pipe 130 to prevent waste liquid leakage and avoid operators from coming into contact with waste liquid or inhaling volatile gases, thereby ensuring personnel safety and preventing pollution of the surrounding environment.
