Description

Technical Field

[0001] This utility model relates to the field of copper melting technology, and in particular to a copper melting solution tank for preventing copper formation. Background Technology

[0002] In the electroless copper plating process for printed circuit boards (PCBs), copper plating solution serves as a key chemical medium used to deposit a conductive copper layer on the surface of a non-conductive substrate. Copper plating solution typically contains copper ions, complexing agents, reducing agents, and stabilizers, and its performance directly affects the plating quality and process stability. In actual production, copper plating solution needs to be recycled to reduce costs and waste discharge. However, during the recycling, storage, and transportation of the solution, copper ions are prone to reduction and precipitation, forming copper crystal particles that deposit on the inner walls of pipes and containers—a phenomenon known as "copper deposition."

[0003] Existing copper smelting solution tanks mostly adopt a simple vertical or horizontal tank structure. The inlet and outlet pipes are usually straight or simply bent, and the pipe openings are mostly horizontal or upward-facing. This structure has the following drawbacks: Copper deposits in pipelines: During intermittent chemical transfer, residual droplets accumulate at the bottom or blind ends of the pipeline due to gravity, and copper particles gradually deposit and adhere, forming crystalline residues. This type of copper deposit can clog pipelines, increase flow resistance, and even detach and contaminate the chemical solution, affecting the uniformity of copper plating.

[0004] Laminar boundary layer buildup: During low-flow-rate inlet or outlet stages, a laminar boundary layer forms near the inner wall of the pipe, where copper particles easily settle and adhere. Conventional pipe structures lack effective disturbance mechanisms. Therefore, a copper-dissolving chemical tank designed to prevent copper buildup is proposed to address this issue. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to provide a copper-free chemical tank that prevents copper formation, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, one embodiment of this utility model provides a copper-free chemical tank for preventing copper formation, comprising a tank body, a main shaft, a tank cover, and an observation window. The top of the tank body is movably connected to the tank cover via the main shaft, and a handle is fixedly connected to the top of the tank cover. An observation window is fixedly connected to the top of the box, an inlet pipe is fixedly connected to the side of the box, and an outlet pipe is fixedly connected to the side of the box. Both the inlet and outlet pipes are bent, and the ends of both the inlet and outlet pipes face downwards. The inlet pipe and outlet pipe are fixedly connected to flanges at their ends, and the inlet pipe and outlet pipe are detachably connected to pipe plugs through the flanges. The plug portion of the pipe plug is inserted into the vertical portion of the inlet pipe and outlet pipe. A spiral guide plate is fixedly connected to the inner wall of the transverse part of the inlet pipe and the outlet pipe, and the direction of the spiral guide plate is in the same direction as the flow of liquid. The end of the spindle is threaded with fasteners.

[0008] Preferably, of any of the above solutions, the housing is made of stainless steel and the observation window is made of tempered glass.

[0009] The above technical solution is adopted: This chemical tank is specifically used to store the copper-melting chemical solution after circulation.

[0010] The lid is always closed on the top of the tank, and the state of the liquid inside the tank can be seen through the observation window.

[0011] The circulated and filtered medicine solution is passed through pipes and inlet pipes into the tank for storage.

[0012] When reusing, the medicine is pumped away through pipes and outlet pipes for reuse.

[0013] Preferably, in any of the above embodiments, the inlet pipe is located above the outlet pipe, and the inlet pipe, outlet pipe and the housing are all welded together.

[0014] The above technical solution is adopted. The core structure of this device consists of an inlet pipe, an outlet pipe, and a spiral guide plate. The inlet and outlet pipes are designed with 90-degree bends, and their ports are set downwards. This prevents the liquid from being deposited inside the inlet and outlet pipes due to gravity, thus preventing copper crystals from forming and remaining. Spiral guide vanes are fixedly connected to the inner walls of the transverse sections of the inlet and outlet pipes. The direction of the spiral guide vanes is aligned with the flow direction of the liquid, not obstructing the flow but agitating the liquid. During inlet operation: the liquid enters through the inlet pipe, and the spiral guide vanes create a slight vortex, reducing stagnation at the pipe opening and preventing sedimentation. The liquid flows directly into the tank, avoiding accumulation at the port. During outlet operation: the liquid is drawn out of the tank, and the fluid generates a slight vortex under the action of the spiral guide vanes, resulting in rapid output.

[0015] Preferably, in any of the above embodiments, the flange and the pipe plug are assembled by a number of bolts and nuts, and the spiral guide plate is welded to the inner wall of the inlet pipe and the outlet pipe.

[0016] Device Structure: Body: The main container is made of stainless steel and has an open top. Main Shaft: Mounted on the top side edge of the body, locked at both ends by washer-nut type fasteners. Cover: Movably connected to the body via the main shaft, with a fixed handle on top, normally kept closed. Observation Window: Made of tempered glass, embedded in the top side wall of the body, for visual monitoring of liquid level and status.

[0017] Inlet and outlet pipes: Both are 90° bent structures, made of stainless steel pipes welded to the side of the tank; the inlet pipe is located above the outlet pipe, and the ends of both pipes are vertically downward; the inner wall of the horizontal section is welded with 5-6mm thick stainless steel spiral guide plates; the end flange is connected to the pipe plug by bolts and nuts, and the pipe plug is inserted into the vertical pipe section.

[0018] Liquid inlet stage: The liquid enters through the inlet pipe, and the spiral guide vanes guide the fluid to form an axial vortex. This vortex disrupts the laminar boundary layer, increases the shear force on the pipe wall, and makes it difficult for copper particles to adhere.

[0019] Discharge stage: During the pumping process, the spiral guide vanes accelerate the fluid rotation and flow, reduce the velocity gradient at the outlet section, and prevent particle deposition.

[0020] Preferably, the spiral guide plate has a thickness of 5-6 mm and is made of stainless steel.

[0021] Preferably, of any of the above solutions, the fastener is a washer nut, which is tightened to lock the angle of the cover.

[0022] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This anti-copper-forming copper-melting solution tank is designed with an inlet pipe, an outlet pipe, and a spiral guide plate. The inlet and outlet pipes are bent at 90 degrees, and their ends face downwards. This prevents the solution from settling inside the inlet and outlet pipes due to gravity, thus preventing copper crystals from forming and remaining. Helical guide vanes are fixedly connected to the inner walls of the transverse sections of the inlet and outlet pipes. The direction of the helical guide vanes is in the same direction as the liquid flow, which does not obstruct the flow but can disturb the liquid. During liquid inlet: the liquid enters through the inlet pipe, and the helical guide vanes create a slight vortex in the liquid, reducing stagnation at the pipe opening and preventing deposition. The liquid flows directly into the tank, avoiding accumulation at the port. During liquid outlet: the liquid is drawn out of the tank, and the fluid generates a slight vortex under the action of the helical guide vanes, resulting in rapid output. In the liquid inlet stage: the liquid enters through the inlet pipe, and the helical guide vanes guide the fluid to form an axial vortex. This vortex disrupts the laminar boundary layer, increases the shear force on the pipe wall, and makes it difficult for copper particles to adhere.

[0023] Discharge stage: During the pumping process, the spiral guide vanes accelerate the fluid rotation and flow, reduce the velocity gradient at the outlet section, and prevent particle deposition.
