[0001] The utility model relates to the technical field of degreasing tanks for electroplating, and more specifically, to a dynamic degreasing mechanism for electroplating solution tanks. Background Art

[0002] During the electroplating production process, parts need to be immersed in different solution tanks. Due to the diverse initial surface conditions of the parts, there are often excess substances such as oil stains, cutting fluids, dust, or debris attached.

Detailed implementation manners

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0023] During the electroplating production process, parts need to be immersed in different solution tanks. Due to the diverse initial surface conditions of the parts, there are often redundant substances such as oil stains, cutting fluids, dust or debris attached. Therefore, multiple and various types of cleaning are required to ensure surface cleanliness. However, the solution in the solution tank will also be contaminated after multiple cleanings. Currently, in the industry, the cold water tank and hot water tank generally ensure water quality by continuously updating the flowing water. For the degreasing tank and acid-base tank, due to cost considerations, only the new tank solution can be replaced regularly. During the replacement cycle, oil stains will float on the surface of the tank solution and impurities will precipitate at the bottom, which may adhere to the surface of the parts when the parts enter and exit the solution tank, affecting the electroplating quality.

[0024] Therefore, the present utility model provides a dynamic degreasing mechanism for an electroplating solution tank. Figure 1 is a perspective view of a dynamic degreasing mechanism for an electroplating solution tank provided by an embodiment of the present utility model; Figure 2 is a cross-sectional view of a dynamic degreasing mechanism for an electroplating solution tank provided by an embodiment of the present utility model;

[0025] Figure 3 is a top view of a dynamic degreasing mechanism for an electroplating solution tank provided by an embodiment of the present utility model; Figure 4 is a side view of a dynamic degreasing mechanism for an electroplating solution tank provided by an embodiment of the present utility model; As Figures 1 to 4 shown, the dynamic degreasing mechanism for the electroplating solution tank includes:

[0026] An electroplating tank 1, and the electroplating tank 1 includes: an electroplating area 2 filled with electroplating solution, an adsorption area 3 for adsorbing oil stains and impurities on the surface of the electroplating solution, and a cavity area 4 for receiving pure electroplating solution;

[0027] Specifically, a circulation pump 8 is provided in the electroplating area 2 for pushing the electroplating solution in the electroplating area 2 towards the adsorption area 3. A filter cotton 10 is provided in the adsorption area 3 for adsorbing oil stains and impurities; the adsorption area 3 is isolated from the cavity area 4 by a filter cotton partition 11; the electroplating area 2 and the adsorption area 3 are separated by an overflow partition 17.

[0028] Recovery tank 5, the recovery tank 5 is connected to the cavity area 4; the recovery tank 5 includes: an oil film secondary recovery area 6 and a plating solution recovery area 7; the adsorption area 3 is connected to the oil film secondary recovery area 6 for secondarily adsorbing the oil stains that flow into the recovery tank 5 and are not adsorbed cleanly; the plating area 2 is connected to the plating solution recovery area 7 for absorbing the plating solution in the plating solution recovery area 7.

[0029] Specifically, the recovery tank 5 is connected to the cavity area 4 through a connecting pipe 9; for receiving the pure plating solution in the cavity area 4; the recovery tank 5 includes: an oil film secondary recovery area 6 and a plating solution recovery area 7, which are separated by a recovery tank partition 18. The oil film secondary recovery area 6 is provided with a secondary recovery pump 12; the secondary recovery pump 12 is connected to the adsorption area 3 through a secondary recovery pipeline 13; the plating solution recovery area 7 is provided with a main circulation pump 14 and a rectangular recovery pipeline 15 for absorbing the plating solution; the main circulation pump 14 is connected to the plating area 2 through a main recovery pipeline 16; through holes are provided on the rectangular recovery pipeline 15 and the secondary recovery pipeline 13.

[0030] In this application, the plating tank 1 and the recovery tank 5 form a circulating flow of the plating solution through the connecting pipe 9 and the main recovery pipeline 16.

[0031] The specific circulation process is as follows:

[0032] First, power on each water pump (i.e., the circulation pump 8, the secondary recovery pump 12, and the main circulation pump 14) to make it in a working state. At this time, after the circulation pump 8 starts, a surge is formed to push the surface plating solution in the plating area 2, that is, from the position of the circulation pump 8 towards the overflow partition 17. At this time, the oil stains and impurities floating on the surface of the plating solution are pushed over the overflow partition 17 (that is, over the top of the overflow partition 17) and enter the adsorption area 3 for adsorption and filtration; the adsorption area 3 is filled with multiple layers of filter cotton 10, and the filter cotton 10 has the ability to adsorb oil stains and impurities; through multiple layers of filtration and adsorption, the relatively pure plating solution will pass through the filter cotton partition 11 and enter the lower cavity area 4, and then enter the recovery tank 5 through the connecting pipe 9.

[0033] Because after the oil stains and impurities accumulate to a certain extent, they may pass through the filter cotton 10 and the filter cotton partition 11 and enter the cavity area 4, and then enter the recovery tank 5. At this time, the heavier impurities will settle at the bottom of the recovery tank 5, and the lighter oil stains will float on the top of the recovery tank 5. In order to avoid secondary pumping back of the impurities settled at the lower part of the recovery tank 5 and the oil stains floating on the surface, the rectangular recovery pipeline 15 (i.e., the water inlet of the main circulation pump 14) is placed in the upper middle part in the recovery tank 5 (i.e., in the electroplating solution recovery area 7); the oil stains overflow to the oil film secondary recovery area 6 through the recovery tank partition 18 (i.e., over the top of the recovery tank partition 18), and are re-transported to the adsorption area 3 for adsorption through the secondary recovery pump 12 and the secondary recovery pipeline 13 (through holes are provided on the secondary recovery pipeline 13 for the oil stains to flow in); the electroplating solution (the impurities are at the bottom and the oil stains are at the upper part, so impurities and oil stains will not be sucked in) sucked by the main circulation pump 14 through the rectangular recovery pipeline 15 (through holes are provided on the rectangular recovery pipeline 15) is re-discharged into the electroplating area 2 of the electroplating tank 1 through the main recovery pipeline 16.

[0034] Through the above cycle, the electroplating solution in the electroplating area 2 is replenished, and then is pushed into the adsorption area 3 by the circulation pump 8 again for adsorption, so as to form a dynamic filtering effect, and the pre-plating treatment and electroplating work of parts can be carried out simultaneously during the filtering process.

[0035] This application makes full use of various types of water pumps to carry out large circulation of the electroplating solution, combines the characteristics of pollutants, and treats them by physical methods such as filtering, adsorption and precipitation, which greatly prolongs the service life of the electroplating solution. It only needs to replace the filter cotton 10 regularly and clean the impurities settled at the bottom of the recovery tank 5, reduces the frequency of bath solution replacement and material cost, and avoids the problems of resource waste and high chemical treatment cost caused by the discharge of a large amount of solution and impurity mixture simply using the overflow plate in the traditional electroplating tank 1.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
