Abstract
Description
Technical Field
[0001] This utility model relates to the field of electroplating tank technology, specifically to an electroplating tank that is not prone to the adhesion of impurities. Background Technology
[0002] Electroplating tanks operate on the principle of electrolysis. During electroplating, the workpiece to be plated serves as the cathode, and the metal to be plated serves as the anode, both immersed in an electroplating solution containing ions of the desired metal. When a DC power supply is applied, an oxidation reaction occurs at the anode, causing metal atoms to lose electrons and become ions that enter the electroplating solution. Simultaneously, the metal ions in the electroplating solution gain electrons at the cathode surface, are reduced to metal atoms, and deposited on the workpiece surface, thus forming a uniform and dense metal coating.
[0003] In existing electroplating tanks, impurities inevitably accumulate during the electroplating process. These impurities deposit on the tank walls, forming a thick scale layer. This scale layer typically has poor thermal conductivity, hindering heat exchange between the electroplating tank and the outside environment. For example, the thermal conductivity of scale is much lower than that of metal materials. When scale forms on the electroplating tank walls, it is equivalent to forming a heat insulation layer between the tank walls and the electroplating solution, making heat transfer difficult during heating or cooling. Therefore, to address these issues, an electroplating tank that is less prone to impurity adhesion is proposed. Utility Model Content
[0004] The purpose of this invention is to provide an electroplating tank that is less prone to the adhesion of impurities, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An electroplating tank that is not prone to impurity adhesion includes a shell, support legs, and an electroplating tank. Four symmetrically arranged support legs are fixedly connected to the bottom of the shell. The electroplating tank is fixedly connected inside the shell, and its inner side is coated with a PTFE layer. A motor is fixedly connected to the left side of the shell. A rotating shaft penetrating the shell, the electroplating tank, and the PTFE coating is fixedly connected to the output end of the motor. Symmetrically arranged connecting rods are fixedly connected to the bottom of the rotating shaft. A first fixing plate is fixedly connected to the bottom of one set of connecting rods. A symmetrically arranged first cleaning brush is fixedly connected to the bottom of the first fixing plate. A first cleaning plate, which is fixedly connected to a first fixing plate, is fixedly connected to the cleaning brushes. A fixing rod is fixedly connected to one side of the connecting rod. A second fixing plate is fixedly connected to the end of the fixing rod away from the connecting rod. A second cleaning brush, which is symmetrically arranged, is fixedly connected to the side of the second fixing plate away from the fixing rod. A second cleaning plate, which is fixedly connected to a second fixing plate, is fixedly connected to a group of second cleaning brushes. A filter screen is provided inside the PTFE coating. A magnetic ring is magnetically connected to the bottom end of the filter screen. A drain pipe, which is fixedly connected to the magnetic ring, is fixedly connected to the inside of the electroplating tank and the outer shell. A plug is provided inside the drain pipe.
[0007] Preferably, the second fixing plate, the second cleaning plate, and the two second cleaning brushes are a set, and there are two sets of the second fixing plate, the second cleaning plate, and the two second cleaning brushes, which are symmetrically arranged on the inner side of the PTFE coating.
[0008] Preferably, the inner shape of the electroplating tank is U-shaped, and the inner shape of the electroplating tank matches the shape of the PTFE coating.
[0009] Preferably, the outer diameter of the magnet ring matches the outer diameter of the drain pipe, and the inner diameters of the magnet ring and the drain pipe are smaller than the outer diameter of the filter screen.
[0010] Preferably, the filter screen, magnetic ring, drain pipe and plug are a group, and are arranged in a relatively central position inside the housing.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In this utility model, the electroplating tank, PTFE coating, motor, rotating shaft, connecting rod, first fixing plate, first cleaning brush, first cleaning plate, fixing rod, second fixing plate, second cleaning brush, and second cleaning plate are all included. The PTFE coating prevents almost no substances from adhering to the inside of the electroplating tank, thus preventing scale buildup. It also possesses good chemical stability, corrosion resistance, and high-temperature resistance. The first cleaning brush and first cleaning plate scrape off and clean any remaining scale on the inner wall of the electroplating tank. The second cleaning brush and second cleaning plate further clean the scale. The cleaning plate scrapes off and cleans the small amount of scale at both ends of the electroplating tank, effectively preventing scale buildup. This solves the problem that impurities inevitably accumulate in existing electroplating tanks during the electroplating process. These impurities deposit on the walls of the electroplating tank to form a thick scale layer. This scale layer usually has poor thermal conductivity, which hinders heat exchange between the electroplating tank and the outside world. Taking common scale as an example, the thermal conductivity of scale is much lower than that of metal materials. When scale forms on the walls of the electroplating tank, it is equivalent to forming a heat insulation layer between the tank wall and the electroplating solution, causing the heat transfer to be poor during the heating or cooling process of the electroplating tank.
[0013] 2. In this utility model, the water discharged from the electroplating tank can be filtered by setting a filter screen to avoid pipe blockage. The filter screen can be attracted by the magnetic ring below it. When the filter screen needs to be cleaned, it can be quickly removed by simply lifting it upwards. Attached Figure Description

[0021] Please see Figure 1-3 This utility model provides a technical solution:
[0022] An electroplating tank that is not prone to impurity adhesion includes a shell 1, support legs 2, and an electroplating tank 3. Four symmetrically arranged support legs 2 are fixedly connected to the bottom of the shell 1. The electroplating tank 3 is fixedly connected inside the shell 1, and a PTFE coating 4 is provided on the inner side of the electroplating tank 3. A motor 5 is fixedly connected to the left side of the shell 1. A rotating shaft 6, penetrating the shell 1, the electroplating tank 3, and the PTFE coating 4, is fixedly connected to the output end of the motor 5. Symmetrically arranged connecting rods 7 are fixedly connected to the bottom of the rotating shaft 6. A first fixing plate 8 is fixedly connected to the bottom of a set of connecting rods 7. Symmetrically arranged first cleaning brushes 9 are fixedly connected to the bottom of the first fixing plate 8. A series of first cleaning brushes 9 are fixedly connected to each other. A first cleaning plate 10 is fixedly connected to a first fixing plate 8. A fixing rod 11 is fixedly connected to one side of a connecting rod 7. A second fixing plate 12 is fixedly connected to the end of the fixing rod 11 away from the connecting rod 7. A second cleaning brush 13 arranged symmetrically is fixedly connected to the side of the second fixing plate 12 away from the fixing rod 11. A second cleaning plate 14 fixedly connected to the second fixing plate 12 is fixedly connected between a group of second cleaning brushes 13. A filter screen 15 is provided inside the PTFE coating 4. A magnetic ring 16 is magnetically connected to the bottom end of the filter screen 15. A drain pipe 17 fixedly connected to the magnetic ring 16 is fixedly connected to the inside of the electroplating tank 3 and the outer shell 1. A plug 18 is provided inside the drain pipe 17.
[0023] The second fixing plate 12, the second cleaning plate 14, and the two second cleaning brushes 13 form a group. There are two groups of the second fixing plate 12, the second cleaning plate 14, and the two second cleaning brushes 13, which are symmetrically arranged inside the PTFE coating 4. The two groups of the second fixing plate 12, the second cleaning plate 14, and the two second cleaning brushes 13 can simultaneously prevent impurities from adhering to both ends of the electroplating tank 3. The inner shape of the electroplating tank 3 is U-shaped, and the inner shape of the electroplating tank 3 matches the shape of the PTFE coating 4, which is conducive to the complete coverage of the electroplating tank 3 by the PTFE coating 4. The outer diameter of the magnetic ring 16 matches the outer diameter of the drain pipe 17. The inner diameter of the magnetic ring 16 and the drain pipe 17 is smaller than the outer diameter of the filter screen 15 to prevent the filter screen 15 from falling into the drain pipe 17. The filter screen 15, the magnetic ring 16, the drain pipe 17, and the plug 18 form a group and are arranged in a relatively central position inside the outer casing 1.
[0024] Workflow: When an electroplating tank that is not prone to impurity adhesion is required, the entire device is powered externally. First, the PTFE coating 4 ensures that almost no substances adhere to the inside of the electroplating tank 3, making it difficult for scale to adhere to its surface. It also possesses good chemical stability, corrosion resistance, and high-temperature resistance. The output of the motor 5 drives the rotating shaft 6 to rotate. The rotating shaft 6, through the connecting rod 7 and the fixing rod 11, drives the first fixing plate 8, the first cleaning brush 9, and the first cleaning plate 10, as well as the second fixing plate 12, the second cleaning brush 13, and the second cleaning plate 14 to rotate. The first cleaning brush 9, the first cleaning plate 10, and the first cleaning plate 10, along with the second fixing plate 12, the second cleaning brush 13, and the second cleaning plate 14, rotate through the first cleaning brush 9. The cleaning brush 9 and the first cleaning plate 10 scrape off and clean the small amount of scale remaining on the inner wall of the electroplating tank 3. The second cleaning brush 13 and the second cleaning plate 14 scrape off and clean the small amount of scale at both ends of the electroplating tank 3, effectively preventing the accumulation of scale. The filter screen 15 can filter the water discharged from the electroplating tank 3 to prevent the pipe from getting blocked. The filter screen 15 can be attracted by the magnetic ring 16 below it. When the filter screen 15 needs to be cleaned, it can be quickly removed by simply pulling it upwards. The wastewater in the electroplating tank 3 can be discharged through the drain pipe 17 by removing the plug 18.
