Description

Technical Field

[0001] This utility model relates to the field of electroplating tank technology, and in particular to an electroplating tank with bottom residue cleaning function. Background Technology

[0002] Electroplating tanks are the core equipment in the electroplating process, generating electroplating residues such as metal hydroxides and anolyte mud during operation. If these residues are not removed promptly and effectively, they will accumulate at the bottom of the tank, potentially affecting the purity and chemical stability of the electroplating solution, leading to defects and reduced adhesion in the plating layer. They can also clog pipes and filtration systems, increasing maintenance costs and impacting production continuity. Current technologies for cleaning residues at the bottom of electroplating tanks primarily employ intermittent manual cleaning during shutdowns or external independent filtration and circulation systems. Manual cleaning is labor-intensive, inefficient, and the downtime significantly impacts production efficiency; while external filtration systems have drawbacks such as large footprint, high initial investment and operating costs, and limited effectiveness in cleaning residues adhering to the complex internal structure of the tank. Especially for electroplating tanks with settling structures, the inner walls of the central transition area are prone to residue adhesion and accumulation, forming difficult-to-clean dead zones that conventional methods struggle to address. Utility Model Content

[0003] This utility model relates to an electroplating tank with bottom residue cleaning, which can realize automated and continuous internal cleaning, and is especially effective in removing residues attached to the settling area of ​​the electroplating tank.

[0004] In a first aspect, this utility model provides an electroplating tank with bottom residue cleaning capability, specifically comprising: a base frame; an electroplating tank mounted on the upper end of the base frame, the electroplating tank being vertically assembled from an electroplating float box, an electroplating check box, and an electroplating sink box, with the electroplating float box at the top, the electroplating check box in the middle, and the electroplating sink box at the bottom, the inner cavities of the electroplating float box, the electroplating check box, and the electroplating sink box being interconnected, and the upper end of the electroplating float box being an open end; a control box being fixedly mounted on the front side wall of the base frame; a cleaning shaft being laterally rotatably mounted in the middle of the electroplating check box; a conveying shaft being rotatably mounted in the middle of the lower end of the electroplating sink box; and a motor being fixedly mounted on one side wall of the electroplating sink box, the motor being used to drive the conveying shaft to rotate.

[0005] Optionally, a support frame with uniform longitudinal spacing is provided at the connection between the bottom of the inner cavity of the electroplating float box and the upper end of the inner cavity of the electroplating anti-reverse box.

[0006] Optionally, the electroplating check box is an hourglass-shaped structure that is wide at both ends and narrow in the middle.

[0007] Optionally, the lower end of the electroplating caisson has a semi-circular structure, and a discharge pipe is fixed vertically downward at one end of the bottom of the electroplating caisson.

[0008] Optionally, the conveying shaft is provided with a spiral conveying paddle, the edge of which is tangent to the inner wall of the electroplating caisson.

[0009] Optionally, the cleaning shaft is provided with a bidirectional spiral thread, and a cleaning disc is screwed onto the cleaning shaft. Cleaning scrapers are fixed on both sides of the cleaning disc. The two cleaning scrapers have a "V" shape structure. The cleaning scrapers are tangent to the inclined side wall at the upper end of the inner cavity of the electroplating check box. Both sides of the cleaning scrapers are cutting edges.

[0010] This utility model provides an electroplating tank with bottom residue cleaning function, which has the following beneficial effects: This invention achieves efficient and automated cleaning of electroplating residue by designing the electroplating tank with a unique structure consisting of a vertically connected electroplating float, an electroplating check valve, and an electroplating settling tank, and integrating an automatic cleaning and conveying mechanism. Its specific benefits are as follows: First, the device utilizes the principle of gravity settling combined with a specific structure to achieve natural separation and efficient collection of residue. The hourglass-shaped structure of the electroplating check valve not only effectively prevents liquid backflow caused by bottom turbulence, ensuring the stability of the process in the upper electroplating float, but also constructs an ideal residue settling channel; while the semi-circular structure at the bottom of the electroplating settling tank facilitates residue aggregation. Second, the device achieves simultaneous automated cleaning of residue from two different locations. On one hand, a motor drives the conveyor shaft to rotate, using its spiral conveyor paddle to stably and continuously transport the precipitated residue collected at the bottom of the electroplating settling tank to the discharge pipe for discharge, solving the problem of bottom residue accumulation. On the other hand, an innovative cleaning mechanism consisting of a cleaning shaft, a cleaning disc, and a V-shaped cleaning scraper is set up inside the electroplating check box. The bidirectional spiral thread on the cleaning shaft can drive the cleaning scraper to reciprocate along the axial direction when it rotates. In addition, the design of the cleaning scraper being tangent to the inner wall of the hourglass-shaped structure and having double-sided cutting edges enables it to efficiently scrape off the residue attached to the inclined inner wall like an "inner wall cleaning robot," effectively preventing the traditional problem of the hourglass neck being blocked. The scraped residue is then guided into the sedimentation path and finally discharged by the bottom conveying mechanism. Attached Figure Description

[0016] Among them, a longitudinally spaced support frame 201 is provided at the connection between the bottom of the inner cavity of the electroplating float box 2 and the upper end of the inner cavity of the electroplating anti-reverse box 3.

[0017] Among them, the electroplating check valve box 3 is an hourglass-shaped structure that is wide at both ends and narrow in the middle.

[0018] The lower end of the electroplating caisson 4 is a semi-circular structure, and a discharge pipe 401 is fixed vertically downward at one end of the bottom of the electroplating caisson 4.

[0019] The conveyor shaft 7 is equipped with a spiral conveyor paddle, the edge of which is tangent to the inner wall of the electroplating caisson 4.

[0020] In Example 2, based on Example 1, a bidirectional spiral thread is provided on the cleaning shaft 8, and a cleaning disc 801 is screwed onto the cleaning shaft 8. Cleaning scrapers 802 are fixed on both sides of the cleaning disc 801. The two cleaning scrapers 802 have a "V" shaped structure. The cleaning scrapers 802 are tangent to the inclined side wall at the upper end of the inner cavity of the electroplating check box 3. Both sides of the cleaning scrapers 802 are cutting surfaces.

[0021] The following further explains and clarifies the function and effect of each structure mentioned above, so that those skilled in the art can better understand the technical solution: The base frame 1 provides stable support to ensure the overall structure of the electroplating tank is solid; the electroplating tank is composed of an electroplating float box 2, an electroplating check box 3, and an electroplating settling box 4, which are vertically spliced ​​together in sequence, with interconnected inner cavities. The electroplating float box 2 is located at the top and has an open end, which facilitates electroplating operation and flotation of light materials. The electroplating check box 3 is located in the middle and is designed as an hourglass-shaped structure that is wide at both ends and narrow in the middle, which effectively prevents liquid backflow and promotes the settling of residues. The electroplating settling box 4 is located at the bottom and has a semi-circular structure at the bottom, which is conducive to collecting and storing the settled heavy residues; the bottom of the electroplating float box 2 and the upper end of the electroplating check box 3 are provided with longitudinally spaced support frames 201, which enhance structural stability and assist in the separation of materials; the bottom of the electroplating settling box 4... A discharge pipe 401 is fixed vertically downward at one end of the unit to facilitate centralized discharge of residues; a control box 5 is fixedly mounted on the front side wall of the base frame 1 for centralized control of the entire system operation; a motor 6 is fixedly mounted on the side wall of one end of the electroplating settling tank 4, and the motor 6 drives the conveyor shaft 7 to rotate. The conveyor shaft 7 is equipped with a spiral conveyor paddle, the edge of which is tangent to the inner wall of the electroplating settling tank 4 to achieve efficient conveying of sedimented residues to the discharge pipe 401; a cleaning shaft 8 is horizontally rotatably installed in the middle of the electroplating check box 3. The cleaning shaft 8 is equipped with a bidirectional spiral thread and a cleaning disc 801 is screwed on it. V-shaped cleaning scrapers 802 are fixed on both sides of the cleaning disc 801. The cleaning scrapers 802 are tangent to the inclined side wall of the upper end of the inner cavity of the electroplating check box 3 and both sides are cutting surfaces. The rotation of the cleaning shaft 8 drives the cleaning scrapers 802 to scrape off the residues attached to the inner wall, preventing accumulation and maintaining smooth flow.

[0022] Working Principle: During use, the electroplating solution and workpieces are primarily placed in the upper electroplating float tank 2 for electroplating operations. Residue generated during the process naturally separates due to differences in specific gravity: lighter slag floats on the surface of the liquid in the electroplating float tank 2, while heavier sediment settles downwards under gravity. The residue first passes through the support frame 201 at the bottom of the electroplating float tank 2, which provides support while allowing the residue to pass through. Subsequently, the residue enters the middle electroplating check tank 3, whose unique hourglass-shaped structure effectively slows down liquid turbulence, forming a relatively stable settling channel, thereby promoting further downward collection of the residue to the bottom electroplating settling tank 4. The semi-circular structure at the bottom of the electroplating settling tank 4 is highly conducive to collecting and converging these sediments. When cleaning is required, the motor 6 is activated via the control box 5. The motor 6 drives the conveyor shaft 7 to rotate. The spiral conveyor paddle on the shaft, designed to be tangential to the inner wall of the electroplating settling tank 4, continuously pushes the residue accumulated at the bottom towards the discharge pipe 401, achieving automated conveying and removal of the bottom residue. Simultaneously, the cleaning mechanism also begins operation. The cleaning shaft 8 rotates, driving the screw-connected cleaning disc 801 and its two V-shaped cleaning scrapers 802 along the cleaning shaft 8 axially via its bidirectional spiral thread. Because the cleaning scrapers 802 are designed to be tangential to the inclined sidewall at the upper end of the inner cavity of the electroplating check box 3 and have cutting edges on both sides, they efficiently scrape off the residue adhering to the inner wall of the hourglass-shaped structure during movement, preventing its accumulation and blockage, and peeling it into the settling path, ultimately falling into the electroplating settling tank 4 for unified processing by the conveyor shaft 7.
