Description

Technical Field

[0001] This utility model relates to the technical field of plating solution circulation control devices, and in particular to a plating solution circulation control device for a sodium-aluminum metallized thin film. Background Technology

[0002] Metallization is a coating process that deposits a thin metal film on the surface of a non-metallic material using physical or chemical methods. This process is widely used in electronics, optics, aerospace, and other fields, significantly improving the material's electrical conductivity, thermal conductivity, wear resistance, corrosion resistance, and optical properties. Sodium-aluminate diffusion coating is an important process in the production of metallized films. By depositing a metallized film containing sodium and aluminum on the film surface, sodium-aluminate diffusion coating can further optimize the film's performance, such as improving its stability under specific environments and enhancing its adhesion to subsequent coatings.

[0003] Existing coating systems suffer from unstable coating quality due to the deposition of elements such as sodium and aluminum on the film surface during continuous coating. As these elements are consumed, the concentration of the coating solution decreases. To maintain the concentration within a suitable range, it is necessary to continuously replenish sodium and aluminum compounds. However, current replenishment methods cannot monitor the concentration in real time and replenish materials promptly, leading to replenishment only when the concentration is too low, affecting coating quality. Existing methods involve pouring a large amount of material into the coating solution at once, causing oversaturation and excessively high concentration, affecting coating uniformity. Furthermore, once the solution is saturated, the remaining material cannot dissolve, forming precipitates or suspended particles. These precipitates or suspended particles not only interfere with the coating process but also cause surface defects or unevenness. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sodium-aluminum metallized film plating solution circulation control device includes a plating tank, an outlet at the bottom of the plating tank and an inlet on the side wall of the plating tank, an outlet pipe installed at the bottom of the outlet, the other end of the outlet pipe connected to a preparation tank, the preparation tank also connected to an inlet pipe, the other end of the inlet pipe connected to the inlet of the plating tank. The top of the configuration tank is provided with a storage hopper, the bottom of the storage hopper is provided with a feed inlet, and one end of the bottom of the feed inlet is connected to the configuration tank. A discharge valve is rotatably connected inside the feed inlet, and a drive shaft coaxial with the configuration tank is rotatably connected inside the configuration tank. The top end of the drive shaft passes through the top wall of the configuration tank and is driven to connect to the discharge valve.

[0006] Preferably, a first on / off valve is installed between the liquid outlet and the connection end of the liquid outlet pipe, and a first pump body is also installed on the liquid outlet pipe.

Therefore, they should not be construed as limitations on this utility model.

[0018] Example, refer to Figures 1-6 A sodium-aluminum metallized film plating solution circulation control device includes a plating tank 1, a liquid outlet 11 at the bottom of the plating tank 1, and a liquid inlet 12 on the side wall of the plating tank 1. A liquid outlet pipe 2 is installed at the bottom of the liquid outlet 11, and the other end of the liquid outlet pipe 2 is connected to a preparation tank 3. The preparation tank 3 is also connected to a liquid inlet pipe 4, and the other end of the liquid inlet pipe 4 is connected to the liquid inlet 12 of the plating tank 1. The top of the preparation tank 3 is equipped with a storage hopper 5, and the bottom of the storage hopper 5 is equipped with a feed inlet. One end of the feed inlet is connected to the bottom of the preparation tank 3. A discharge valve 7 is rotatably connected inside the feed inlet. A drive shaft 6 coaxial with the preparation tank 3 is rotatably connected inside the preparation tank 3. The top of the drive shaft 6 passes through the top wall of the preparation tank 3 and is driven to connect with the discharge valve 7. In use, the plating solution in the coating tank 1 flows out through the bottom outlet 11, flows into the preparation tank 3 through the outlet pipe 2, and then returns to the inlet 12 of the coating tank 1 through the inlet pipe 4 of the preparation tank 3, forming a plating solution circulation. The storage hopper 5 is used to load compound raw materials such as sodium and aluminum. The raw materials enter the preparation tank 3 through the feed inlet. The drive shaft 6 is linked with the discharge valve 7 to control the discharge amount of the raw materials. During the circulation of the plating solution, the concentration of the plating solution is always maintained within the range required for processing by adding raw materials to the plating solution.

[0019] Furthermore, a first on / off valve 21 is installed between the outlet 11 and the connection end of the outlet pipe 2, and a first pump body 22 is installed on the outlet pipe 2. In use, the first on / off valve 21 between the outlet 11 and the connection end of the outlet pipe 2 is used to control the opening and closing of the outlet 11 to prevent the plating solution from leaking. The first pump body 22 on the outlet pipe 2 is used to provide power to extract the plating solution in the plating tank 1 and transport it to the preparation tank 3.

[0020] Furthermore, a second on / off valve 41 and a second pump body 42 are installed on the inlet pipe 4. In use, the second on / off valve 41 on the inlet pipe 4 is used to control the opening and closing of the inlet pipe 4, and the second pump body 42 is used to provide power to transport the plating solution in the preparation tank 3 back to the coating tank 1 to prevent the plating solution from flowing back.

[0021] Specifically, the first pump body 22 and the second pump body 42 are preferably 50ZXPB20-30 type stainless steel self-priming pumps. The main body of this type of self-priming pump is made of stainless steel, which has strong corrosion resistance and is suitable for conveying electroplating solutions.

[0022] Furthermore, a drive motor 61 is connected to one end of the bottom of the drive shaft 6 through the bottom wall of the configuration tank 3. Several sets of stirring paddles 64 are connected to the shaft of the drive shaft 6 inside the configuration tank 3. In use, the drive motor 61 drives the drive shaft 6 to rotate, and the drive shaft 6 drives the stirring paddles 64 to rotate, stirring the plating solution in the configuration tank 3 and the raw materials that enter the configuration tank 3 through the bottom feed channel 51 of the hopper, so that the raw materials and plating solution are fully mixed.

[0023] Specifically, the preferred model of the drive motor 61 is MXM542-1501E-H. This type of drive motor 61 is suitable for conveying various chemical media, including strong acids, strong alkalis and organic solvents. It is very suitable for driving the transmission shaft 6 to rotate the stirring paddle 64, stirring the plating solution and promoting the mixing between the plating solution and the raw materials.

[0024] Furthermore, several sets of stirring paddles 64 are equidistantly arranged around the shaft of the drive shaft 6. In use, when the drive shaft 6 rotates, the stirring paddles 64 can uniformly stir the plating solution in the preparation tank 3, ensuring that the stirring paddles 64 can uniformly stir the plating solution, so that the components in the plating solution are fully mixed, and avoiding local concentrations that are too high or too low.

[0025] Furthermore, a drive bevel gear 62 is fixedly connected to the top of the drive shaft 6 through the configuration tank 3, and a driven shaft 63 coaxially connected to it is fixedly connected inside the feed valve 7. One end of the driven shaft 63 is fixedly connected to a driven bevel gear 631 through the side wall of the feed channel 51. The driven bevel gear 631 meshes with the drive bevel gear 62. In use, the drive bevel gear 62 at the top of the drive shaft 6 meshes with the driven bevel gear 631 on the driven shaft 63 inside the feed valve 7. When the drive shaft 6 rotates, the drive bevel gear 62 drives the driven bevel gear 631 to rotate, thereby driving the feed valve 7 to rotate, and thus controlling the opening and closing of the feed channel 51, so that the raw material enters the configuration tank 3 through the feed channel 51 and mixes with the plating solution, thereby keeping the plating solution within a certain concentration range.

[0026] Furthermore, the feeding valve 7 has several recessed connecting grooves 71 around its outer periphery. In use, when the feeding valve 7 rotates, a certain amount of raw material is contained in the connecting grooves 71 and rotates to the bottom end of the feeding channel, so that the raw material enters the preparation tank 3 under the action of gravity and mixes with the plating solution. The feeding valve 7 has several connecting grooves 71 around its outer periphery, which can control and slow down the amount of raw material fed at one time, and avoid excessive raw material entering the preparation tank 3, which would cause the plating solution to become oversaturated.

[0027] Working principle: Prepare compound raw materials such as sodium and aluminum, load the raw materials into storage hopper 5, ensuring sufficient raw materials in storage hopper 5, open the first shut-off valve 21 and the second shut-off valve 41, start the first pump body 22 and the second pump body 42, so that the plating solution in the coating tank 1 flows into the preparation tank 3 through the outlet 11 and the outlet pipe 2, and then returns to the inlet 12 of the coating tank 1 through the inlet pipe 4, forming a plating solution circulation. Start the drive motor 61, drive the transmission shaft 6 to rotate, and through the meshing of the driving bevel gear 62 and the driven bevel gear 631, drive the discharge valve 7 to rotate. The connecting groove 71 on the discharge valve 7 quantitatively carries the raw materials and sends them into the preparation tank 3 to mix with the plating solution. The drive motor 61 drives the transmission shaft 6 to rotate, and the transmission shaft 6 drives the stirring paddle 64 to rotate, stirring the plating solution and raw materials in the preparation tank 3. The paddle 64 is equidistantly arranged around the shaft of the drive shaft 6, which can uniformly stir the plating solution and ensure that the components in the plating solution are fully mixed. During the circulation of the plating solution and the addition of raw materials, the concentration of the plating solution is monitored regularly. If the concentration of the plating solution is too low, the rotation speed of the feeding valve 7 can be appropriately increased to increase the amount of raw materials fed; if the concentration of the plating solution is too high, the rotation speed of the feeding valve 7 can be appropriately slowed down to reduce the amount of raw materials fed. After the concentration of the plating solution reaches the processing requirements, the circulation of the plating solution is maintained, and the plating solution in the coating tank 1 is used for the coating operation of sodium aluminum diffusing metallization film. During the coating process, by controlling the reciprocating circulation of the plating solution between the coating tank 1 and the preparation tank 3, and by continuously adding raw materials to the preparation tank 3 and stirring and mixing the plating solution and raw materials, the concentration of the plating solution is ensured to be within the range most suitable for coating production.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
