TECHNICAL FIELD

[0002] At present, the most widely used steel material in the industry is corroded to varying degrees when used in the atmosphere, seawater, soil and building materials. In order to ensure the normal use of steel products and prolong their service life, the corrosion protection technology of steel has always been widely concerned by people. Hot-dip galvanizing is one of the most effective means to delay the environmental corrosion of steel materials. It is to immerse the steel product with cleaned and activated surface into molten zinc liquid, and through the reaction and diffusion between iron and zinc, a well-adhered zinc alloy coating is formed on the surface of the steel product. At present, hot-dip galvanizing products mainly include steel plates, steel strips, steel wires and steel pipes, among which hot-dip galvanized steel plates account for the largest proportion. For a long time, hot-dip galvanizing process has been favored by people because of its low plating cost, excellent protection characteristics and beautiful appearance.

[0003] When the amount of products to be galvanized is large, the products to be galvanized are usually placed in a lifting tool, and then the lifting tool is immersed into a galvanizing tank, so that the galvanizing of a large amount of products is completed. However, when using the solvent method for hot-dip galvanizing, a large amount of smoke will be generated, and the main component of the smoke is acidic gas volatilized by heating. Once the amount of these gases exceeds the limit and disperses into the air, the operators of the electroplating will be poisoned. SUMMARY

[0026] In summary, the beneficial technical effects of the present application are:

[0027] 1. When the galvanizing device is used, the workpiece to be electroplated is placed in the storage groove of the lifting basket, and then the lifting frame is rotated, so that the lifting frame is rotated from the first state located outside the galvanizing tank to the second state located in the galvanizing tank. During the rotation, the lifting basket continuously maintains a vertical state under the action of gravity, the lifting frame and the lifting basket pass through the feeding channel, and in the second state, the lower end of the lifting basket is immersed in the electroplating solution. When electroplating, the acidic gas generated will be collected by the gas collecting cover and discharged along the exhaust pipe, so that most of the acidic gas enters the exhaust pipe along the gas collecting cover, effectively reducing the amount of acidic gas discharged into the air.

[0028] 2. A first shield and a second shield are provided at the rotation axis of the spreader frame. Both the first shield and the second shield are perpendicular to the spreader frame and rotate with the spreader frame. When the spreader frame is in the first position, the second shield blocks the feed channel. When the Danfeng spreader frame is in the second position, the first shield blocks the feed channel. This allows the feed channel to be blocked during electroplating and when placing workpieces to be electroplated into the spreader basket, thereby further reducing the chance of acidic gases generated in the galvanizing bath mixing into the air.

[0029] 3. When the first baffle follows the spreader frame to rotate from the first state to the second state, the first baffle drives the flip slide to rotate 180 degrees, and the flip slide abuts the lower end surface of the blocking plate. When the second baffle rotates from the second state to the first state with the spreader frame, the first baffle drives the flip slide to rotate 180 degrees, and the flip slide abuts the upper end surface of the blocking plate, and the rotation axis of the flip slide is lower than the rotation axis of the spreader basket. When the first baffle follows the spreader frame to rotate from the second state to the first state, the first baffle drives the flip slide to rotate. During the rotation, the flip slide abuts the switch plate on one side of the bottom of the spreader basket, so that as the spreader frame continues to rotate, the spreader basket will gradually rotate to a horizontal state and abut the upper end of the flip slide, so that the spreader basket will be flipped during the rotation of the spreader frame, thereby making unloading more convenient.

The rotating shaft of the waste receiving plate 19 is located away from the hanger basket 13. The waste receiving plate 19 and the bottom wall of the galvanizing tank 1 are welded with a compression spring 20.

The galvanizing tank 1 is provided with a waste collecting bin 21 on the upper end of the waste receiving plate 19. The waste collecting bin 21 is located on the side of the rotating shaft of the waste receiving plate 19 and abuts against the inner side wall of the galvanizing tank 1. The waste collecting bin 21 is provided with a waste collecting opening 22 on the side end close to the hanger basket 13.

[0049] The implementation principle of the embodiment is as follows:

[0050] When the galvanizing device is used, the workpiece to be electroplated is placed in the receiving groove 17 of the hanger basket 13, and then the hanger frame 12 is rotated so that the hanger frame 12 is rotated from the first state located outside the galvanizing tank 1 to the second state located inside the galvanizing tank 1. During the rotation, the hanger basket 13 continuously maintains the vertical state under the action of gravity, and the first shutter 14 rotates the turnover slide 24 so that the turnover slide 24 is rotated to the lower end surface of the magnetic blocking plate 26, and the hanger frame 12 and the hanger basket 13 pass through the feeding passage 9 until the first shutter 14 abuts against the side end of the gas collecting cover 2. In the second state, the first shutter 14 seals and blocks the feeding passage 9 under the action of the sealing rubber sheet 16, and at this time, the second shutter 15 abuts against the waste receiving plate 19 and is rotated to the horizontal state, and the lower end of the hanger basket 13 is immersed in the electroplating solution. When electroplating, the generated acidic gas will be collected by the gas collecting cover 2 and discharged into the exhaust pipe 7 along the gas collecting cover 2 so that most of the acidic gas enters the exhaust pipe 7 along the gas collecting cover 2. When the electroplating is completed, the hanger frame 12 is rotated from the second state to the first state. During the rotation, the second shutter 15 and the waste receiving plate 19 are disengaged, the compression spring 20 drives the waste receiving plate 19 to the inclined state, and the residue will roll along the waste receiving plate 19 and enter the waste collecting bin 21 along the waste collecting opening 22. At this time, part of the acidic gas leaks from the feeding passage 9, and at this time, the air blowing exhaust 10 blows toward the residual gas collecting cover 11 so as to blow the overflowed acidic gas into the residual gas collecting cover 11 and then into the exhaust pipe 7. The first shutter 14 rotates the turnover slide 24 by 180 degrees at the outside of the galvanizing tank 1. During the rotation of the turnover slide 24, the turnover slide 24 abuts against the push plate 28 at one side of the bottom of the hanger basket 13, so that as the hanger frame 12 continues to rotate, the hanger basket 13 will gradually rotate to the horizontal state and abut against the upper end of the turnover slide 24, so that the hanger basket 13 is turned over during the rotation of the hanger frame 12. At this time, the electroplated workpiece can be pulled out of the hanger basket 13. During the process that the hanger frame 12 is rotated from the first state to the second state, the first shutter 14 rotates the turnover slide 24. During the rotation, the turnover slide 24 is in the inclined state and is connected to the conveying slide 25, and the electroplated workpiece can directly roll to the conveying slide 25 and be conveyed under the action of gravity.

Therefore, any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
