Description

Technical Field

[0001] The invention relates to the technical field of nickel plating tank heating, in particular to an energy-saving nickel plating tank heating device. Background Art

[0002] In nickel plating production, the temperature control accuracy and energy efficiency of the nickel plating tank heating device directly affect the coating quality and production costs. Traditional heating devices generally have key problems such as poor heating uniformity, rapid heat loss and insufficient circulation capacity:

[0003] Most of them use fixed heating components that act directly on the electrolyte, lacking active stirring or liquid circulation structures. This leads to significant temperature differences between the upper and lower layers of the electrolyte in the tank. In particular, the upper layer of the liquid surface is prone to rapid temperature drops due to its large contact area with the air and rapid heat dissipation. This results in uneven plating deposition rates and varying surface quality. At the same time, traditional devices lack an effective heat recycling mechanism. The electrolyte relies solely on natural convection or simple piping for limited flow, and is unable to continuously and evenly diffuse the heat from the heated area throughout the tank. This not only leads to low heating efficiency and increased energy consumption, but also affects the stability of the nickel plating process due to temperature fluctuations.

[0004] In addition, the single heating and driving method makes it difficult for the equipment to dynamically adjust liquid flow and heat distribution according to production needs, further exacerbating problems such as uneven heating, energy waste and high maintenance costs, and it is difficult to meet the needs of modern industrial nickel plating for efficient, stable and energy-saving equipment.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0035] See also Figures 1-8 As shown, the purpose of this embodiment is to provide an energy-saving nickel plating tank heating device, including a tank body 1, which is divided into two parts. A sealing plate 2 is provided at the connection between the two parts of the tank body 1. The sealing plate 2 is fixed by screws 3 to fix the two parts of the tank body 1 into a complete nickel plating tank;

[0036] It also includes: a heating chamber 7, which is opened inside the tank body 1, and a heating tube 36 is fixedly connected to the inner wall of the heating chamber 7. The inner cavity of the heating chamber 7 is provided with a stirring assembly for stirring the liquid in the heating chamber 7; a leakage tube 6, the top of the leakage tube 6 is connected to the inner cavity of the tank body 1, and the bottom end of the leakage tube 6 passes through the interior of the heating chamber 7. The inner cavity of the heating chamber 7 is provided with a control assembly adapted to the leakage tube 6, and the control assembly is used to control the communication and closing of the leakage tube 6; a driving chamber 18 is opened in the inner cavity of the tank body 1 and located at the bottom of the heating chamber 7, and a driving assembly is provided inside the driving chamber 18. The driving assembly is used to drive the stirring assembly and the control assembly, and the stirring assembly includes a rotating rod 9, which is located inside the heating chamber 7, and the bottom end of the rotating rod 9 passes through the driving chamber 18 and extends to the interior of the driving chamber 18. The top of the heating chamber 7 is fixedly connected to a rotating plate 10, one side of the rotating plate 10 is fixedly connected to a stirring plate 11, and one side of the stirring plate 11 is fixedly connected to a slide plate 12.

[0037] Furthermore, the tank body 1 is constructed as a split upper and lower structure, secured together by a sealing plate 2 and screws 3. The edge of the sealing plate 2 is embedded with an acid- and alkali-resistant sealing ring, forming a tight seal with the contact surface of the tank body 1. The heating chamber 7 is completely separated from the bottom drive chamber 18 by an insulating partition, and the inner wall of the drive chamber 18 is treated with corrosion protection.

[0038] The split design allows for quick disassembly of the tank body 1, allowing direct access to easily maintained components such as the leakage pipe 6 and filter screen 5 in the heating chamber 7, greatly simplifying the daily maintenance process and avoiding the disadvantage of the traditional integrated tank body 1 requiring the entire machine to be drained of electrolyte for maintenance.

[0039] The double protection of the sealing plate 2 and the insulating partition not only prevents the leakage of electrolyte from affecting the driving components, but also prevents the motor 19, gears and other power components from being corroded by liquid, ensuring the long-term stable operation of the equipment.

[0040] It solves the problems of inconvenient maintenance and insufficient sealing of traditional devices, makes equipment disassembly and assembly faster, significantly reduces the risk of liquid leakage, and ensures production safety and continuity.

[0041] Furthermore, the stirring assembly consists of a rotating rod 9, a rotating plate 10, a stirring plate 11, and a sliding plate 12. The rotating rod 9 passes through the heating chamber 7 and the drive chamber 18. The rotating plate 10 is fixed at an inclined angle to the middle of the rotating rod 9. The stirring plate 11 at the end is a curved blade with a spoiler structure on the outer edge. The sliding plate 12 rotates with the stirring plate 11, and the end thereof slides in a groove inside the rotating disk 15 of the control assembly.

[0042] When the stirring plate 11 rotates, its inclination angle and turbulent structure force the electrolyte to form a spiral flow, breaking the static layer of the liquid, increasing the contact area with the heating tube 36, promoting uniform heat diffusion, and realizing the transition from local heating to overall convection. The sliding of the slide plate 12 in the slide groove of the rotating disk 15 provides regular triggering power for the control component, so that the stirring action and liquid circulation are naturally coordinated without the need for an additional control system.

[0043] The flow efficiency of the electrolyte in the heating chamber 7 is significantly improved, the temperature stratification phenomenon is effectively eliminated, the temperature of the nickel plating working area is ensured to be uniform, and the plating quality defects caused by local overheating or overcooling are avoided, thereby providing a stable temperature environment for the nickel plating process.

[0044] See also Figure 2-Figure 6As shown, the control component includes a rotating disk 15, which is located in the inner cavity of the heating chamber 7. The bottom of the rotating disk 15 is fixedly connected to a support rod 14, one end of the support rod 14 is fixedly connected to a circular plate 13, and the bottom of the circular plate 13 is fixedly connected to a sleeve rod 8, which is located on the outside of the rotating rod 9 and is rotatably connected to the rotating rod 9. The sleeve rod 8 passes through the driving cavity 18 and extends to the inside of the driving cavity 18. The inner side of the rotating disk 15 is slidably connected to the slide plate 12. A circular groove 16 is provided on the top of the rotating disk 15, and the bottom end of the leakage tube 6 is in contact with the circular groove 16. A leakage hole 17 adapted to the leakage tube 6 is provided on the circular groove 16.

[0045] Furthermore, the control assembly includes a sleeve rod 8, a circular plate 13, a support rod 14, and a rotating disk 15. The sleeve rod 8 is sleeved onto the outside of the rotating rod 9 and connected to the drive assembly via a gear train. The rotating disk 15 is fixed to the top of the sleeve rod 8 and has a leakage hole 17 formed on the disk surface that matches the leakage tube 6. A dynamic sealing structure is provided around the leakage hole 17.

[0046] Intermittent circulation: The driving component rotates the rotating disk 15 at a low speed through gear transmission, and the leakage hole 17 is periodically aligned with the outlet of the leakage pipe 6 to achieve controllable release of electrolyte between the working area and the heating chamber 7, avoiding the risk of overheating caused by uncontrolled flow. The distribution and number of leakage holes 17 are designed to flexibly adjust the liquid circulation frequency according to process requirements, adapt to different heating rates and insulation requirements, and realize intelligent control of the heating process. By releasing electrolyte on demand and coordinating the circulation backflow after heating, the liquid is prevented from overheating or heat waste, ensuring that the temperature of the nickel plating working area is stable within the process requirements, and improving the accuracy of the heating process and energy utilization efficiency.

[0047] See also Figure 7 As shown, the drive assembly includes a motor 19, which is fixedly connected to the bottom of the drive chamber 18. The output end of the motor 19 is fixedly connected to a rotating rod 20 through a coupling. The surface of the rotating rod 20 is fixedly connected to a first bevel gear 21. The rotating rod 9 extends to one end inside the drive chamber 18 and is fixedly connected to a second bevel gear 22. The second bevel gear 22 meshes with the first bevel gear 21. The surface of the rotating rod 20 and one side of the first bevel gear 21 is fixedly connected to a third bevel gear 23. One side of the inner wall of the drive chamber 18 is fixedly connected to a telescopic rod 24. The telescopic end of the telescopic rod 24 is fixedly connected to a ring 25. The inner side of the ring 25 is rotatably connected to a connecting rod 26. The bottom of the connecting rod 26 is fixedly connected to a fourth bevel gear 29, which meshes with the third bevel gear 23. The top of the connecting rod 26 is fixedly connected to a large gear 27. The end of the sleeve rod 8 extending to the inside of the drive chamber 18 is fixedly connected to a small gear 28, which meshes with the small gear 28.

[0048] The drive assembly is powered by a single motor 19, which transmits power to the stirring and control components synchronously via the bevel gears and gear train on the rotating rod 20. The tensioning mechanism, consisting of a telescopic rod 24 and a ring 25, automatically adjusts the gear meshing clearance.

[0049] The single motor 19 drives the stirring component at high speed and the control component at low speed at different speeds through multi-stage gear transmission, thereby achieving efficient power distribution of "high-speed stirring and low-speed circulation" and avoiding energy waste and synchronous control difficulties caused by multiple motors 19 driving.

[0050] Stable transmission: The tensioning mechanism compensates for gear wear, ensuring the stability and accuracy of power transmission, reducing the risk of transmission failure due to component tolerances or long-term operation, simplifying the power system structure, improving energy efficiency, and reducing equipment energy consumption and maintenance costs. At the same time, stable transmission performance ensures the synergy of stirring and circulation control, making the liquid flow and heating process more compatible.

[0051] See also Figure 8 As shown, a placement cavity 30 is provided inside the trough body 1 and on both sides of the heating chamber 7. A power pump 31 is fixedly connected to the inside of the placement cavity 30. One side of the power pump 31 is connected to a water suction pipe 32. One end of the water suction pipe 32 extends to the inside of the heating chamber 7. The top of the power pump 31 is connected to a drainage pipe 33. The top of the drainage pipe 33 is fixedly connected to a horizontal pipe 34. The surface of the horizontal pipe 34 is connected to a nozzle 35. The nozzle 35 extends to the surface of the trough body 1. A collecting trough 4 is provided at the bottom of the inner cavity of the trough body 1 and at the top of the leakage pipe 6. The bottom of the collecting trough 4 is engaged with a filter screen 5.

[0052] The placement chambers 30 on either side of the heating chamber 7 house acid- and alkali-resistant power pumps 31, which circulate the heated electrolyte to the nickel plating work area via a suction pipe 32, a drain pipe 33, and nozzles 35 on a transverse pipe 34. The nozzles 35 are arranged at an angle, and the spray flow disturbs the liquid surface, promoting uniform temperature distribution. During downtime, the pumps can be activated independently to flush the interior of the tank 1.

[0053] The circulation system creates a dynamic flow of electrolyte between the heating chamber 7 and the working area, and cooperates with the stirring assembly to ensure uniform temperature throughout the tank 1. This particularly addresses temperature differences caused by heat dissipation at the liquid surface, preventing defects at the edges of the plating layer due to temperature variations. The flushing function automatically removes nickel salt crystals from the side walls of the tank 1, reducing manual intervention, lowering maintenance efforts, and improving equipment cleaning efficiency. The concentrating trough 4 at the bottom of the nickel plating work area, covered by a filter 5, guides the electrolyte toward the leakage pipe 6 while intercepting solid particles in the liquid, such as nickel slag and plating debris. The filter 5 adopts a quick-release design, facilitating regular cleaning.

[0054] It effectively reduces the entry of impurities into the heating chamber 7, prevents the leakage hole 17 and the heating tube 36 from being blocked, ensures the long-term stable operation of the circulation system and the heating components, extends the service life of the core components of the equipment, and reduces the maintenance frequency.

[0055] The stirring component enhances heat exchange through mechanical disturbance, the control component realizes on-demand circulation of electrolyte, and the auxiliary system eliminates the temperature difference of the liquid surface. The synergistic effect of the three significantly improves the temperature uniformity of the electrolyte, fundamentally solving the coating quality problem caused by uneven heating of traditional devices. The single motor 19 power integrated design avoids redundant drive, and intermittent circulation heating reduces invalid heat loss. It is more energy-efficient than traditional solutions and meets the green energy-saving needs of industrial production.

[0056] Tank body 1 is constructed of two halves, upper and lower, secured with a sealing plate 2 and screws for easy disassembly and cleaning without leaking. A stirring element is incorporated into the heating chamber 7, and a rotating rod 9 rotates the stirring plate 11, ensuring full contact between the electrolyte and the heating tube 36 for a more uniform temperature. A motor 19 simultaneously drives stirring and controls liquid circulation, while a leak hole 17 on the rotating disk 15 can be opened and closed as needed, achieving intermittent heating without wasting energy. A filtration and flushing system traps impurities and prevents clogging, while a nozzle 35 also rinses the tank body 1. Overall, this device addresses the issues of uneven heating, power consumption, and difficult maintenance associated with conventional devices.

[0057] Working principle: When the device is turned on, the bottom motor 19 starts to rotate, and through the transmission system composed of gears and bevel gears, it drives two parts to move at the same time:

[0058] Stirring assembly: The motor 19 drives the rotating rod 9 to rotate at high speed, and the stirring plate 11 on the rotating rod 9 rotates accordingly, stirring the electrolyte in the heating chamber 7, allowing the liquid to fully contact the heating tube 36 on the inner wall and heat quickly and evenly.

[0059] Control component: The motor 19 reduces speed through another set of gears, driving the sleeve rod 8 to rotate at a low speed, and the rotating disk 15 on the top of the sleeve rod 8 rotates slowly, and the leakage holes 17 on the disk are periodically aligned with the leakage pipe 6 above.

[0060] When the leakage hole 17 of the rotating disk 15 is rotated to align with the leakage pipe 6, the electrolyte at the bottom of the nickel plating working area will flow into the heating chamber 7 through the leakage pipe 6, be heated by the heating pipe 36, and be stirred by the stirring plate 11, and heat up rapidly.

[0061] The heated liquid is pumped away by the power pumps 31 on both sides and sprayed back to the nickel plating working area through the nozzle 35 on the top, forming a cycle of "heating in the heating chamber 7 → use in the working area → reflux and reheating", so that the electrolyte temperature of the entire tank body 1 remains consistent.

[0062] Before the electrolyte flows back to the heating chamber 7 , it first passes through the filter 5 at the bottom of the working area to intercept impurities such as nickel slag and debris to prevent clogging of the leakage pipe 6 and the heating pipe 36 .

[0063] When the machine is stopped, the power pump 31 is started alone, and the nozzle 35 sprays water to flush the inside of the tank body 1, washing away the crystals and residual impurities on the side wall to keep it clean.

[0064] According to the process requirements, by changing the number of different leak holes 17 of the rotating disk 15 or adjusting the speed of the motor 19, the circulation frequency of the electrolyte can be changed and the heating speed and temperature can be flexibly controlled.

[0065] When the machine is turned off, the rotating disk 15 is rotated to the position where the leakage hole 17 is misplaced, and the leakage pipe 6 is automatically closed to cut off the flow of liquid and avoid heat loss and liquid leakage.

[0066] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
