Description

Technical Field

[0001] This invention relates to the field of electrolytic stripping technology, specifically to an electrolytic apparatus and its operating method for removing plating layers from alloy surfaces. Background Technology

[0002] In the recycling and repair of electroplated metal panels for building curtain walls, panels with substandard electroplating layers must first have the original plating removed through electrolysis before re-electroplating. Electrolytic stripping tanks are typically used for this process. Electrolytic stripping relies on electrochemical oxidation-reduction reactions, dissolving and peeling the metal plating layer from the workpiece surface under a direct current electric field. Simultaneously, metal ions are deposited at the cathode, thus achieving complete removal of the plating. However, current electrolytic stripping tanks are usually monolithic, lacking flexibility. Different sizes of panels cannot be processed with varying current parameters for multi-station, differentiated electrolysis. Furthermore, it's difficult to seal and separate the electrolyte according to panel specifications, affecting the quality of the stripping. Traditional electrolytic stripping tanks also generate large amounts of waste gas during electrolysis, and bubbles form on the workpiece surface, hindering electrolyte penetration and reducing stripping efficiency. Negative pressure electrolytic stripping is also unsuitable, resulting in significant overall pollution and low efficiency.

[0003] Therefore, we propose an electrolytic device and its working method for removing coatings from alloy surfaces. Summary of the Invention

[0014] An electrolytic method for removing plating from alloy surfaces includes the following steps:

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention employs adjustable separators in conjunction with electrolytic mounting components to separate the electrolyte within the mounting components according to different sheet metal specifications and dimensions. This allows for independent electrolytic stripping of the sheet metal, facilitating targeted adjustments to parameters such as current. Furthermore, the multi-station electrolytic stripping method is more efficient. The detachable adjustable separators allow for easy handling of sheets with irregular shapes such as bends, further ensuring the flexibility of the structure. This avoids the problem of insufficient spacing between adjacent adjustable separators, preventing the placement of the workpiece to be stripped. The protective components ensure smooth insertion of the adjustable separators into the sealed slots, preventing excessive accumulation of impurities in the sealed slots as the stripping cycle increases, which could prevent the bottom of the insulating separator from being fully inserted into the sealed slots.

[0020] Using a negative pressure suction device can maintain a negative pressure state inside the electrolytic cell. Maintaining negative pressure suction in real time can help eliminate air bubbles on the surface of the workpiece, making it easier for the electrolyte to penetrate between the workpiece plating layer and the substrate, thus improving the stripping speed. The negative pressure suction method can also promote the emission of harmful gases generated by electrolysis, improving environmental control quality, especially for indoor electrolytic stripping.

[0021] By using a closed solenoid valve in conjunction with a shut-off switch, the closed solenoid valve can be automatically shut off when the operator opens the negative pressure suction cover to take out the workpiece after the electroplating has been removed. Even if the operator manually shuts off the closed solenoid valve and connects to the external negative pressure pump after the electrolytic deplating is completed, it will not cause backflow of electrolytic waste gas.

[0036] The electrolysis mounting component 1 further includes: a sealing slot 103, an electrode plate 104, and a terminal 1041. A row of sealing slots 103 is fixedly installed inside the electrolytic cell 101, and each row of sealing slots 103 has a U-shaped structure.

Terminals 1041 are fixedly installed on each row of electrode plates 104, and the terminals 1041 are sealed and insulated through the side wall of the electrolytic cell 101. The adjustable separators 2 include: an insulating separator 201, a pressing rod 202, and a fastening bolt 203. The insulating separator 201 is slidably inserted into the inside of the sealing slot 103. A rubber pad is attached to the inside of the sealing slot 103; a pressure rod 202 is fixedly installed on the top of the insulating partition plate 201; two fastening bolts 203 are inserted into the pressure rod 202, and the two fastening bolts 203 are threaded onto the electrolytic cell 101 respectively; the insulating partition plate 201 and the sealing slots 103 on both sides are sealed and insulated; the protective component 3 includes: an anti-jamming slide plate 301 and a guide ramp 302, the anti-jamming slide plate 301 is slidably inserted into the sealing slot 103; rubber pads are attached to the inside of the sealing slot 103 on both sides of the anti-jamming slide plate 301; guide ramps 302 are provided on both sides of the top of the anti-jamming slide plate 301; the top of the anti-jamming slide plate 301 and the guide ramp 302 are arc-shaped; the insulating partition plate 201 is used to press down the anti-jamming slide plate 301; protection Component 3 also includes: a compression spring 303; a row of compression springs 303 is fixedly installed at the bottom of the anti-jamming slide plate 301, and the bottom ends of the row of compression springs 303 are respectively fixedly connected to the sealing slot 103; the compression springs 303 are used to push the anti-jamming slide plate 301 upward; the use of adjustable separator 2 in conjunction with electrolytic mounting component 1 can realize the separation of electrolyte in electrolytic mounting component 1 according to different plate specifications and sizes, realize independent electrolytic stripping of plates, facilitate targeted adjustment of parameters such as current, and the multi-station electrolytic stripping method is more efficient. The use of detachable adjustable separator 2 makes it convenient for workers to perform electrolytic stripping of plates with bent or other irregular structures, further ensuring the flexibility of this structure and avoiding the need for adjacent adjustable separators. The problem of insufficient spacing between components 2, making it impossible to insert the workpiece to be deplated, is addressed by the protective component 3. This structure ensures that the adjustable separator 2 can be smoothly inserted into the sealing slot 103, preventing excessive accumulation of impurities in the sealing slot 103 as the deplating cycle increases, thus preventing the bottom of the insulating separator 201 from being fully inserted into the sealing slot 103. This ensures that the insulating separator 201 can be effectively inserted into the sealing slot 103 and can be sealed and fitted by the rubber pad on the inside of the sealing slot 103. The anti-jamming sliding plate 301 can shield the electrolytic deplating deposits, and with the guidance of the guide slope 302, impurities can be prevented from being directly deposited at the bottom of the sealing slot 103. At the same time, it can also achieve automatic downward retraction without affecting the quick disassembly and adjustment of the insulating separator 201.

[0037] The electrolytic suspension component 4 includes: a suspension rod 401, a clamping plate 402, and positioning bolts 403. The two ends of the suspension rod 401 are slidably inserted into two sliding grooves 102. The clamping plate 402 is fixedly installed at the bottom of the suspension rod 401 by bolts. The bottom of the clamping plate 402 has a groove. Three positioning bolts 403 are threaded onto the clamping plate 402, with the ends of the three positioning bolts 403 located in the grooves at the bottom of the clamping plate 402.

Fixedly installed on the electrolytic cell 101; the connecting seat 501 has a threaded hole; a sealing switch 502 is fixedly installed on the connecting seat 501, and the pressing end of the sealing switch 502 protrudes from the top of the connecting seat 501; the negative pressure suction component 6 includes: a negative pressure suction cover 601 and a pressure switch 602, the negative pressure suction cover 601 has a wire hole for sealing the wire connecting the suspension rod 401; the negative pressure suction cover 601 is rotatably installed on the electrolytic cell 101 via a hinge; a rubber ring is provided on the top of the electrolytic cell 101; the negative pressure suction cover 601... A pressure switch 602 is fixedly installed, with its detection end located inside the negative pressure suction cover 601; a row of terminals 1041 and a suspension rod 401 are connected in series with the output of an adjustable DC regulated power supply; the pressure switch 602 is electrically connected to the input of the adjustable DC regulated power supply; the negative pressure suction cover 601 is used to press and seal the switch 502; the use of the negative pressure suction component 6 can maintain the electrolytic cell 101 in a negative pressure state, and the real-time negative pressure suction method can help assist in the elimination of... In addition to removing air bubbles from the workpiece surface, it facilitates the penetration of electrolyte into the workpiece plating layer and substrate, increasing the stripping speed. On the other hand, the negative pressure suction device 6 promotes the emission of harmful gases generated during electrolysis, improving environmental control quality, especially for indoor electrolytic stripping. The pressure switch 602 ensures that the adjustable DC voltage and current regulated power supply connected in series with the terminal 1041 and the suspension rod 401 can be powered on normally to adjust parameters such as electrolysis current after the negative pressure value of the electrolytic cell 101 meets the standard. The structure and control are simple.

[0038] The negative pressure suction component 6 also includes: a connecting bolt 603 and a gas-closing solenoid valve 604. The connecting bolt 603 is inserted into the connecting seat 501; the end of the connecting bolt 603 is threaded into the threaded hole on the connecting seat 501; the gas-closing solenoid valve 604 is fixedly installed on the negative pressure suction cover 601; the sealing switch 502 is electrically connected to the gas-closing solenoid valve 604; the gas-closing solenoid valve 604 is connected to an external negative pressure pump; by using the gas-closing solenoid valve 604 in conjunction with the sealing switch 502, the gas-closing solenoid valve 604 can be automatically closed when the operator opens the negative pressure suction cover 601 to take out the workpiece after electrolytic deplating. Even if the operator directly closes the gas-closing solenoid valve 604 and the external negative pressure pump after completing the electrolytic deplating, it will not cause backflow of electrolytic waste gas.

[0039] An electrolytic method for removing plating from alloy surfaces includes the following steps:

[0040] 1) Place the plate to be deplated by electrolysis in the groove at the bottom of the clamping plate 402, tighten the three positioning bolts 403 to position and clamp the plate to be deplated by electrolysis, and insert the suspension rod 401 into the slide groove 102;

[0041] 2) Close the negative pressure suction cover 601 and thread the connecting bolt 603 onto the connecting seat 501;

[0042] 3) Open the negative pressure pump connected to the air-closing solenoid valve 604. At this time, the adjustable DC voltage and current regulated power supply connected to terminal 1041 and suspension rod 401 is normally connected to the power supply to perform electrolytic stripping.

[0043] The working principle of this embodiment is as follows: When electrolytic stripping is actually performed, the adjustable DC voltage and current regulated power supply connected to each electrode plate 104 can be adjusted independently, a row of insulating partition plates 201 can insulate and separate the electrolyte, and the plates suspended on each suspension rod 401 can be electrolytic stripping independently.

[0044] Place the plate to be electrolytically deplated in the groove at the bottom of the clamping plate 402, then tighten each positioning bolt 403 to press the positioning plate. Then, insert the suspension rod 401 into the slide groove 102 for installation. At this time, keep the workpiece submerged in electrolyte. The suspension rod 401 is connected to the positive terminal, and the suspension rod 401 and the workpiece are electrically connected through the clamping plate 402. The electrode plate 104 is connected to the negative terminal. Then, close the negative pressure suction cover 601, thread the connecting bolt 603 onto the connecting seat 501, and tighten the connecting bolt 603. At this time, the closing switch 502 will be pressed, and the air-closing solenoid valve 604 will open. At this time, the operator can open the negative pressure pump connected to the air-closing solenoid valve 604 to perform negative pressure suction. After the pressure switch 602 detects that the negative pressure value reaches the standard, the terminal 1041 and the suspension rod 401 will be closed. The adjustable DC regulated power supply connected to the hanging rod 401 can be connected to the power supply normally. The staff can adjust parameters such as current. At this time, the electrolytic cell 101 is in a negative pressure state, which is convenient for defoaming. It can also be used to suck up the gas generated by electrolysis. After the electrolytic deplating is completed, when it is necessary to remove the deplated workpiece, the connecting bolt 603 can be rotated to remove it and the negative pressure suction cover 601 can be opened. At this time, the negative pressure in the electrolytic cell 101 disappears, and the adjustable DC regulated power supply connected to the terminal 1041 and the hanging rod 401 is automatically de-energized. At the same time, when the sealing switch 502 is not pressed by the negative pressure suction cover 601, it will also control the gas-closing solenoid valve 604 to automatically close, so as to prevent the backflow of residual electrolytic waste gas in the negative pressure pump connected to the gas-closing solenoid valve 604, and further reduce environmental pollution.

[0045] When the workpiece is large, it is necessary to remove part of the insulating partition plate 201. The fastening bolts 203 on the corresponding pressure rod 202 can be directly rotated and removed. At this time, the insulating partition plate 201 can be pulled out to expand the placement space of the workpiece. After the insulating partition plate 201 is pulled out, the anti-jamming slide plate 301 is no longer pressed down. Under the elastic compression of the compression spring 303, the anti-jamming slide plate 301 can be pushed up and protrude from the bottom edge of the sealing slot 103. With the help of the guide slope 302 and the arc structure on the outside of the guide slope 302 and the anti-jamming slide plate 301, the amount of plating deposits accumulated on the top of the anti-jamming slide plate 301 can be effectively reduced. If the insulating partition plate 201 needs to be reinstalled later, it can be inserted into the sealing slot 103 again. At this time, the insulating partition plate 201 can squeeze the two guide slopes 302 and press down the anti-jamming slide plate 301. The anti-jamming slide plate 301 can retract without affecting the sealing of the rubber pad inside the sealing slot 103.
