Description

Technical Field

[0001] This utility model relates to an immersion device, specifically an immersion device for passivating copper products, belonging to the technical field of passivation immersion devices. Background Technology

[0002] In the copper products processing industry, copper metal pipes are widely used in building pipelines, electrical equipment, and mechanical parts due to their excellent electrical and thermal conductivity and ductility. However, under natural environmental conditions or during use, the surface of copper metal pipes is prone to chemical reactions with air and moisture, forming an oxide layer. This not only affects the appearance but also reduces their corrosion resistance and shortens their service life. Therefore, passivation treatment is necessary to form a dense passivation film on the surface of copper metal pipes, isolating them from external corrosive media and improving product durability.

[0003] However, existing equipment often uses a single mesh structure or a fixed-interval grid structure for the basket. Copper metal pipes need to be laid horizontally or vertically inside the basket. After the copper pipes are laid, there is no clear separation gap between them. Workers need to reach into the basket and pull them out layer by layer, which is inefficient. At the same time, when the copper pipes are laid, the contact parts of adjacent copper pipes (such as the pipe wall joints) will form a closed space, which the passivation liquid cannot penetrate into the area, resulting in the inability to form a passivation film at the contact parts and poor passivation effect. Utility Model Content

The adjustment components can be flexibly adjusted according to the diameter of the copper tubes, and the isolation rods are horizontally and parallelly distributed, dividing the space inside the basket into multiple layers of placement space.

[0017] Please see Figures 1-6 As shown, an immersion device for passivating copper products includes an immersion tank 1. Walking components 2 are provided on both sides of the immersion tank 1. A lifting component 3 is provided on the walking components 2. Two suspension rods 5 are suspended from the lifting component 3. A basket 6 is fixedly connected to the bottom end of the two suspension rods 5. An adjusting component 4 is provided on the basket 6. The adjusting component 4 includes a sliding groove 401. The basket 6 has two parallel sliding grooves 401. Multiple sliders 402 are provided in each sliding groove 401. Two opposing sliders 402 form a group. An isolation rod 406 for isolating copper metal tubes is rotatably connected between two sliders 402 in the same group. A push block 403 is slidably connected to one of the sliders 402 in each group. A locking post 404 is fixedly connected to the push block 403. The suspended basket 6 has multiple slots 405 arranged linearly, with locking posts 404 engaging with the slots 405. A spring 409 is fixedly connected between the push block 403 and the slider 402. A guide shaft 408 passes through the inside of the spring 409 and is fixedly connected to the inside of the slider 402. The push block 403 is slidably connected to the guide shaft 408. Two guide rods 407 are fixedly connected to the suspended basket 6, and the slider 402 is slidably connected to the guide rods 407. The adjustment component 4 can flexibly adjust the spacing according to the diameter of the copper tube, and the isolation rods are horizontally parallel, dividing the space inside the suspended basket into multiple layers of placement space. Multiple layers of copper tubes can be pulled out at the same time, improving the retrieval efficiency, while reducing the contact between copper tubes, completely avoiding stacking, and improving the passivation effect.

[0018] As a technical optimization of this utility model, the soaking tank 1 includes a cleaning tank 101, an acid pickling tank 102, a passivation tank 103, and a rinsing tank 104. The cleaning tank 101, acid pickling tank 102, passivation tank 103, and rinsing tank 104 are arranged in sequence according to the moving direction of the walking component 2. The tanks are arranged in sequence according to the moving direction of the walking component 2 to form an assembly line operation, eliminating the need for manual handling of metal pipes, greatly reducing the labor intensity of workers, and ensuring smooth connection between each process, thereby improving the efficiency of passivation operation.

[0019] As a technical optimization of this utility model, the walking component 2 includes supporting angle steel 201. Multiple supporting angle steels 201 are linearly arrayed on both sides of the soaking pool 1. Mounting plates 202 are fixedly connected to the multiple supporting angle steels 201. Two side plates 203 are fixedly connected to each mounting plate 202. A first screw 204 is rotatably connected between two opposing side plates 203. A gantry frame 205 is threaded onto the two first screws 204. A lifting component 3 is provided on the gantry frame 205. A first driving member 206 is fixedly connected to each of the two side plates 203 at the same end. The output end of the first driving member 206 is fixedly connected to the first screw 204. Two bases 207 are fixedly connected to the bottom end of the gantry frame 205. Four sliding sleeves 208 are fixedly connected to the bottom end of the bases 207. Two slide rails 209 are fixedly connected to each mounting plate 202. The sliding sleeves 208 and slide rails 209 are slidably connected. Next, after placing the copper metal pipe inside the suspended basket 6 and isolating it with the isolation rod 406, the walking assembly 2 and the lifting assembly 3 are started to perform passivation work. When the walking assembly 2 is working, the mounting plates 202 on the supporting angle steel 201 on both sides of the soaking pool 1 provide stable support for the overall structure. The first drive component 206 (preferably a motor) on the two side plates 203 at the same end starts synchronously, driving the first screw 204 between the opposite side plates 203 to rotate. Since the gantry frame 205 is threadedly connected to the first screw 204, and the sliding sleeve 208 on the bottom base 207 of the gantry frame 205 is slidably connected to the slide rail 209 on the mounting plate 202, the cooperation between the slide rail 209 and the sliding sleeve 208 can limit the rotation of the gantry frame 205, so that the rotational motion of the first screw 204 is converted into the linear motion of the gantry frame 205 along the slide rail 209, ensuring the stability of the gantry frame 205 during movement and preventing the metal pipe inside the suspended basket 6 from shaking.

[0020] As a technical optimization of this utility model, the lifting assembly 3 includes a second screw 301. Two second screws 301 are rotatably connected to the gantry frame 205. A lifting seat 302 is threaded onto the second screw 301. Two suspension bars 304 are fixedly connected between the two lifting seats 302. A suspension rod 5 is suspended on the suspension bars 304. The lifting seat 302 is slidably connected to the gantry frame 205. Two second driving members 303 are fixedly connected to the gantry frame 205. The output end of the second driving member 303 is fixedly connected to the second screw 301. Two guide columns 305 are fixedly connected to the gantry frame 205. The lifting seat 302 is slidably connected to the guide columns 305. The basket 6 is lifted and lowered by the suspension bars 304 and suspension rod 5 between the lifting seats 302, realizing the immersion and removal of the metal tube.

[0021] In use, this utility model first adjusts the adjusting component 4 according to the specifications of the copper metal tube to be passivated. Specifically, the operator pulls the push block 403 away from the slider 402. The push block 403 slides along the slider 402 and compresses the spring 409. At this time, the locking pin 404 on the push block 403 disengages from the locking groove 405 on the basket 6, releasing the limitation on the slider 402. Since two parallel guide rods 407 are fixedly connected to the basket 6, the slider 402 is slidably connected to the guide rods 407. The guide rods 407 provide stable guidance for the movement of the slider 402, preventing the slider 402 from deviating during movement. The operator can slide the slider 402 along the groove 401 and the guide rods 407 to adjust the distance between the relative sliders 402 in the same group, thereby changing the distance between the isolation rod 4. Position 06 allows the spacing between adjacent isolation rods 406 to adapt to different styles of copper metal tubes. After adjustment, release the push block 403, and the spring 409 pushes the push block 403 back to its original position under its own elastic force. The locking post 404 re-engages into the corresponding slot 405 to fix the slider 402. At the same time, the guide shaft 408 that runs through the inside of the spring 409 can prevent the spring 409 from bending and deforming during the extension and retraction process, ensuring the stability of the sliding of the push block 403. This adjustment component 4 can flexibly adjust the spacing between the isolation rods 406, which can effectively isolate copper metal tubes of different diameters, prevent the metal tubes from colliding with each other during the immersion process and causing surface damage, and ensure that there is sufficient gap between the metal tubes, so that the passivation liquid and other liquids can fully contact the surface of the metal tubes and improve the passivation effect. After placing the copper metal pipe inside the suspended basket 6 and isolating it with the isolation rod 406, the walking assembly 2 and the lifting assembly 3 are started to perform passivation work. When the walking assembly 2 is working, the mounting plates 202 on the supporting angle steel 201 on both sides of the soaking pool 1 provide stable support for the overall structure. The first drive component 206 (preferably a motor) on the two side plates 203 at the same end starts synchronously, driving the first screw 204 between the opposite side plates 203 to rotate. Since the gantry frame 205 is threadedly connected to the first screw 204, and the sliding sleeve 208 on the bottom base 207 of the gantry frame 205 is slidably connected to the slide rail 209 on the mounting plate 202, the cooperation between the slide rail 209 and the sliding sleeve 208 can limit the rotation of the gantry frame 205, so that the rotation of the first screw 204 can be turned. The gantry 205 moves linearly along the slide rail 209, ensuring the stability of the gantry 205 during movement and preventing the metal tubes inside the basket 6 from shaking. When the lifting assembly 3 is working, the second drive component 303 (preferably a motor) on the gantry 205 is activated, driving the second screw 301 to rotate. The lifting seat 302 is threadedly connected to the second screw 301 and slidably connected to the guide column 305 on the gantry 205. The guide column 305 can provide vertical guidance for the lifting seat 302, preventing the lifting seat 302 from deviating during lifting. The rotation of the second screw 301 drives the lifting seat 302 to move up and down along the guide column 305, thereby driving the basket 6 to lift and lower through the suspension bar 304 and suspension rod 5 between the lifting seats 302, realizing the soaking and removal of the metal tubes. The immersion operation proceeds in the sequence of cleaning tank 101, pickling tank 102, passivation tank 103, and rinsing tank 104. The traveling assembly 2 moves the gantry frame 205 sequentially above each tank, and the lifting assembly 3 lowers the basket 6, immersing the metal pipes into each tank to complete the cleaning, pickling, passivation, and rinsing processes. The tanks are arranged sequentially according to the direction of travel assembly 2, forming a streamlined operation. This eliminates the need for manual handling of the metal pipes, significantly reducing the labor intensity of workers while ensuring smooth transitions between processes and improving efficiency. The passivation process is efficient; the cleaning tank 101 can remove oil and impurities from the surface of the metal pipe, preventing impurities from affecting the subsequent pickling and passivation effects; the pickling tank 102 can remove the oxide layer on the surface of the metal pipe, laying a good foundation for the passivation treatment; the passivation liquid in the passivation tank 103 can form a passivation film on the surface of the metal pipe, improving the corrosion resistance of the metal pipe; the rinsing tank 104 can remove the residual passivation liquid on the surface of the metal pipe, preventing the passivation liquid from causing secondary corrosion to the metal pipe. Each tank has a clear division of labor, further ensuring the passivation quality of the copper metal pipe.
