Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, and in particular to a device for uniformly filtering and heating electroplating solutions. Background Technology

[0002] Electroplating is a process that uses the principle of electrolysis to deposit a thin layer of other metals or alloys onto the surface of certain metals. It is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (such as copper sulfate), and enhancing aesthetics.

[0003] In the electroplating process, the temperature uniformity and purity of the electroplating solution have a significant impact on the electroplating quality. Existing electroplating devices often suffer from uneven heating, poor solution circulation, and incomplete filtration, leading to uneven electroplated layer thickness, poor surface quality, and affecting product quality. For example, patent application number CN216445493U describes a device for uniformly filtering and heating an electroplating solution. Its working principle involves filtering impurities from the material through the lateral movement of a filter screen. However, gaps exist at the bottom and sides of this filter, preventing it from achieving a good filtration effect. Furthermore, the electroplating solution cannot operate during the filtration process.

[0004] In addition, the existing equipment has an unreasonable structural design, is inconvenient to operate, and is difficult to maintain. In particular, interference is likely to occur between the electroplating mesh frame and the heating components, affecting the heating effect and operational safety. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned problems in the prior art and provide a uniform filtration and heating device for electroplating solutions. This device can achieve uniform heating, effective filtration and circulation stirring of the electroplating solution, improve the quality and efficiency of electroplating, and avoid interference between the electroplating mesh frame and the heating components.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A uniform filtration and heating device for electroplating solution includes a housing with an electroplating tank. A mounting plate is installed on one side of the top of the housing, and a turbine assembly and a filter assembly extending into the electroplating tank are provided on the mounting plate. A heating assembly is provided at the bottom of the housing, and a detachable electroplating mesh frame is provided inside the housing above the heating assembly. A liquid inlet is provided on the outer wall of the housing and connected to a liquid inlet pipe. A liquid outlet is provided at the bottom of the housing and connected to a liquid outlet pipe.

[0008] Preferably, the mounting plate has a motor port, a detection port, a negative port and a filter port. The turbine assembly includes a rotary motor mounted on the mounting plate. The shaft of the rotary motor rotatably passes through the motor port and is fitted with two turbine disks. Several arc-shaped blades are distributed in a circular and equidistant manner between the two turbine disks.

[0009] Preferably, a sealed bearing is provided between the rotating shaft of the rotary motor and the motor port.

[0010] Preferably, the filter assembly includes a liftable filter cylinder, which is slidably connected to the filter port. A limit ring is fixedly connected to the top of the filter cylinder, and a handle is provided on the limit ring. Replaceable block activated carbon is provided inside the filter cylinder.

[0011] Preferably, the mounting plate is also provided with a temperature display screen, which is electrically connected to a temperature detection rod, and the temperature detection rod extends through the detection port into the electroplating tank.

[0015] Preferably, the bottom of the box is also provided with four support feet.

[0016] Compared with the prior art, the electroplating solution uniform filtration and heating device provided by this utility model has the following beneficial effects: This invention utilizes a rotating motor in a turbine assembly to drive two turbine disks to rotate synchronously. These two turbine disks, in turn, drive several arc-shaped blades to rotate, thereby achieving the circulation and stirring of the electroplating solution.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] like Figure 1 and Figure 6As shown, this utility model discloses a uniform filtration and heating device for electroplating solution, including a housing 1. The bottom of the housing 1 is provided with four support feet 14. The housing 1 has an electroplating tank 13. An mounting plate 3 is installed on one side of the top of the housing 1. A turbine assembly 4 and a filter assembly 5 extending into the electroplating tank 13 are provided on the mounting plate 3. A heating assembly 6 is provided at the bottom of the housing 1. A detachable electroplating mesh frame 2 is provided inside the housing 1 above the heating assembly 6. An inlet is provided on the outer wall of the housing 1, and an inlet pipe 11 is connected to the inlet. An outlet is provided at the bottom of the housing 1, and an outlet pipe 12 is connected to the outlet. The support feet 14 are used to support the entire device and improve the stability of the device. The inlet pipe 11 is connected to an external electroplating solution and is used to inject the electroplating solution into the electroplating tank 13 of the housing 1. The outlet pipe 12 is connected to an external waste liquid treatment device (e.g., a waste treatment pool, not shown in the figure) and is used to discharge the waste electroplating solution in the electroplating tank 13.

[0022] like Figure 2 and Figure 3 As shown, the heating component 6 includes a coiled S-shaped heating copper tube 61. Both ends of the heating copper tube 61 extend to one side of the outer wall of the housing 1. An external heat source provides heat to the heating copper tube 61 to heat the electroplating solution. The S-shaped design of the heating copper tube 61 increases the contact area with the electroplating solution, making the heating more uniform.

[0023] like Figures 1 to 5 As shown, the mounting plate 3 has a motor port 31, a detection port 32, a negative electrode port 33, and a filter port 34. The turbine assembly 4 includes a rotary motor 41 mounted on the mounting plate 3. The rotating shaft 42 of the rotary motor 41 rotatably passes through the motor port 31 and is fitted with two turbine disks 43. An arc-shaped blade 44 is fixedly connected between the two turbine disks 43. The rotary motor 41 drives the rotating shaft 42 to rotate, and the rotation of the rotating shaft 42 drives the two turbine disks 43 to rotate synchronously, thereby causing the arc-shaped blade 44 to rotate, realizing the stirring and circulation of the solution. Specifically, a sealed bearing 45 is installed between the rotating shaft 42 of the rotary motor 41 and the motor port 31. The sealed bearing 45 plays a sealing role, which can effectively prevent the leakage of lubricating oil from the sealed bearing 45 and prevent the electroplating solution from leaking from the motor port 31, thus preventing corrosion of the rotary motor 41 and the rotating shaft 42 and extending the service life of the device.

[0024] like Figures 1 to 4 and Figure 7As shown, the filter assembly 5 includes a liftable filter cylinder 51, which is slidably connected to the filter port 34. A limiting ring 52 is fixedly connected to the top of the filter cylinder 51, and a handle 53 is provided on the limiting ring 52. Replaceable block activated carbon is provided inside the filter cylinder 51. The handle 53, the limiting ring 52, and the filter cylinder 51 are all made of non-conductive and non-corrosive materials to prevent electric shock when manually lifting the handle 53 and to ensure the safety of the installation work. The aperture of the filter cylinder 51 is smaller than the size of the workpiece to be electroplated, which can prevent the workpiece from falling out of the filter cylinder 51. The filter cylinder 51 can be lifted out of the filter port 34 by the handle 53, which is convenient for replacing the block activated carbon. The limiting ring 52 plays a limiting role to prevent the filter cylinder 51 from falling completely into the electroplating tank 13.

[0025] like Figures 1 to 4 As shown, a temperature display screen 7 is also provided on the mounting plate 3. The temperature display screen 7 is electrically connected to a temperature detection rod 71. The temperature detection rod extends through the detection port 32 into the electroplating tank 13 to detect the solution temperature in real time and display it on the temperature display screen 7. The mounting plate 3 is also equipped with a negative electrode metal rod 8, which extends through the negative electrode port 33 into the electroplating tank 13. The negative electrode metal rod 8 is also liftable and is slidably connected to the negative electrode port 33. The negative electrode metal rod 8 is made of metal such as copper or nickel. The negative electrode port 33 serves as the negative electrode in the electroplating process. During electroplating, it can provide metal ions to the electroplated workpiece. When the negative electrode port 33 is exhausted, it can be replaced by lifting and lowering.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, the four corners of the electroplating tank 13 in the box 1 are arc-shaped. The arc shape can improve the flow of the circulating electroplating solution, making the circulation smoother and preventing solution stagnation. It also effectively promotes the filtration of the electroplating solution. The electroplating tank 13 is symmetrically provided with guide grooves 131. The outer wall of the electroplating mesh frame 2 is fixedly connected with a guide plate 21 that cooperates with the guide groove 131. The top of the electroplating mesh frame 2 is fixedly connected with a limiting ring plate 22. The limiting ring plate 22 abuts against the top of the box 1, so that the electroplating mesh frame 2 can be stably installed in the electroplating tank 13 and is easy to put in and take out. Specifically, there is a certain distance between the lowest point of the guide groove 131 and the heating copper tube 61. This distance is a specific value of 3-8cm. This can prevent the electroplating frame 2 from contacting the heating copper tube 61, ensure the normal circulation of the solution around the heating component 6, and effectively prevent the electroplating workpiece from being too close to the heating copper tube 61, which would cause uneven electroplating effect due to local high temperature.

[0027] The working process of this utility model is as follows: The workpiece to be electroplated is placed in the electroplating frame 2. The electroplating frame 2 is placed into the electroplating tank 13 by the cooperation of the guide plate 21 and the guide groove 131. The gap between the guide groove 131 and the heating copper tube 61 ensures that the electroplating frame 2 will not come into contact with the heating component 6. Electroplating solution is injected into electroplating tank 13 through liquid inlet, and rotary motor 41 is started to drive arc blade 44 to rotate, so that the solution circulates. Simultaneously, the solution is heated by the heating copper tube 61, and the temperature detection rod 71 monitors the solution temperature in real time and displays it on the temperature display screen 7. The operator can adjust the heating parameters according to the displayed temperature. During the circulation process, the solution passes through the filter screen 51, where block activated carbon adsorbs and filters impurities in the solution to ensure its purity. During the electroplating process, the negative electrode metal rod 8 serves as the negative electrode, and the workpiece serves as the positive electrode to realize the electroplating operation.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
