[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A plating solution circulation filtration device includes a support base 1, a filtration mechanism 2 welded to the right side of the top of the support base 1, and a circulation mechanism 3 installed on the left side of the top of the support base 1. The filtration mechanism 2 includes a filter tank 21, a connecting plate 22, a fixing plate 23, two electric telescopic rods 24, four auxiliary telescopic rods 25, a snap ring 26, a liquid inlet hopper 27, two filter rings 28, and a PLC controller 29. The filter tank 21 is welded to the right side of the top of the support base 1, the connecting plate 22 is welded to the top of the inner side of the filter tank 21, the fixing plate 23 is welded to the bottom of the inner side of the filter tank 21, the electric telescopic rods 24 are respectively installed on the left side of the top of the fixing plate 23 and the right side of the top of the fixing plate 23, and the auxiliary telescopic rods 25 are installed on the top of the fixing plate 23.

[0028] In this embodiment: A filter tank 21 provides a closed space for plating solution filtration, preventing splashing or contamination from external impurities during the filtration process. A connecting plate 22 provides a fixed support point for the drain pipe 31, ensuring a tight connection between the drain pipe 31 and the filter tank 21 to prevent leakage during plating solution transport. Simultaneously, it provides initial guidance for the plating solution entering the filter tank 21, directing it towards the liquid inlet hopper 27 to improve filtration efficiency. A fixing plate 23 provides a stable mounting base for the electric telescopic rod 24 and the auxiliary telescopic rod 25, ensuring the telescopic rods do not wobble during lifting and lowering. The electric telescopic rod 24 can be controlled by a PLC controller 29 to extend and retract, driving the locking ring 26 and the liquid inlet hopper 27 to rise and fall. During maintenance, the liquid inlet hopper 27 can be lowered to the pick-and-place port 4, facilitating the replacement of the filter ring 28 without disassembling numerous parts, significantly reducing maintenance time. The auxiliary telescopic rod 25 extends and retracts synchronously with the electric telescopic rod 24 during lifting and lowering, ensuring the liquid inlet hopper 27 remains horizontal at all times, preventing leakage of the plating solution due to tilting during filtration. The leak-proof, snap-fit ​​ring 26 fixes the liquid-priming funnel 27 through an inner snap-fit ​​structure, enabling quick assembly and disassembly of the liquid-priming funnel 27. Its tight snap-fit ​​with the liquid-priming funnel 27 prevents displacement of the liquid-priming funnel 27 during filtration. Maintenance is also simple; just lift the liquid-priming funnel 27 upwards, simplifying the operation and improving maintenance convenience. The funnel-shaped structure of the liquid-priming funnel 27 collects the plating solution delivered from the drain pipe 31, guiding it evenly to the filter ring 28, preventing localized accumulation of plating solution and insufficient filtration. It also provides installation space for the two filter rings 28, achieving an orderly multi-layer filtration layout and improving plating solution purification efficiency. The filter rings 28 are installed at the top and bottom of the inner side of the liquid-priming funnel 27, forming a double-layer filtration structure that can intercept impurities of different particle sizes in the plating solution, significantly improving the purity of the plating solution. Its movable connection method facilitates individual replacement, reducing unnecessary component wear and maintenance costs. The PLC controller 29 can automatically control the electric telescopic rod 24, adjusting the lifting position of the liquid-priming funnel 27 and reducing human error.

[0029] Specifically, such as Figure 2 , Figure 3 As shown, the snap ring 26 is welded to the top of the electric telescopic rod 24 and the top of the auxiliary telescopic rod 25 respectively. The liquid hopper 27 is snapped into the inner side of the snap ring 26. The filter ring 28 is movably connected to the bottom of the inner side of the liquid hopper 27 and the top of the inner side of the liquid hopper 27 respectively. The PLC controller 29 is installed on the surface of the circulation mechanism 3.

[0030] Specifically, such as Figure 4 As shown, the circulation mechanism 3 includes a drain pipe 31, a circulation pump 32, a suction pipe 33, and an outlet pipe 34. The drain pipe 31 is fixedly connected to the right side of the circulation pump 32.

[0031] Specifically, such as Figure 4As shown, the right side of the drain pipe 31 passes through the top of the filter tank 21 and is fixedly connected to the top of the connecting plate 22. The circulation pump 32 is installed on the left side of the top of the support base 1.

[0032] In this embodiment: by setting up a drain pipe 31, the plating solution drawn by the circulating pump 32 can be stably transported to the inside of the filter tank 21. The circulating pump 32 draws the plating solution from the inside of the electroplating tank through the extraction pipe 33, and transports it to the filter mechanism 2 through the drain pipe 31. After filtration, it is returned to the electroplating tank through the outlet pipe 34 connected to the external pipeline, forming a complete plating solution circulation loop. The extraction pipe 33 can draw the plating solution to be filtered from the external plating solution storage container. The outlet pipe 34, by connecting to the external pipeline, can transport the purified plating solution back to the inside of the electroplating tank.

[0033] Specifically, such as Figure 4 As shown, the liquid extraction pipe 33 is fixedly connected to the left side of the circulating pump 32, the liquid outlet pipe 34 is fixedly connected to the bottom of the filter tank 21, and the PLC controller 29 is installed on the surface of the liquid outlet pipe 31.

[0034] Specifically, such as Figure 5 As shown, a loading port 4 is provided on the right side of the filter tank 21, and a sealing door 5 is rotatably connected to the inside of the loading port 4.

[0035] In this embodiment: by setting up the pick-up and drop-out port 4, a channel is provided for picking up and dropping the liquid hopper 27 and the filter ring 28. The operator can directly contact the liquid hopper 27 after it has descended through the pick-up and drop-out port 4 without disassembling the overall structure of the filter tank 21, which greatly simplifies the maintenance operation. By setting up the sealing door 5, the pick-up and drop-out port 4 can be sealed when closed, preventing the plating solution from splashing or external dust and impurities from entering the filter tank 21 during the filtration process, ensuring the purity of the plating solution and the safety of operation. When opened, it does not occupy extra space, which is convenient for the operator to carry out maintenance work.

[0036] Specifically, such as Figure 5 As shown, a handle 6 is welded to the right rear side of the sealed door 5, and the surface of the handle 6 is engraved with anti-slip texture.

[0037] Specifically, such as Figure 5 As shown, a reinforcing base 7 is fixedly connected to the bottom of the circulating pump 32. The bottom of the reinforcing base 7 is welded to the top of the support base 1, and the surface of the reinforcing base 7 is coated with an anti-corrosion coating.

[0038] In this embodiment: by providing a handle 6, the operator can apply force to open or close the sealing door 5, making it convenient to open or close the sealing door 5 quickly. By providing anti-slip texture, the friction between the hand and the handle 6 is increased, preventing slippage when the hand is wet, thus improving the safety and convenience of operation. By providing a reinforcing base 7, the installation stability of the circulation pump 32 can be enhanced, and the vibration generated during the operation of the circulation pump 32 can be reduced. By providing anti-corrosion coating, the possible dripping erosion of plating solution can be resisted, extending the service life of the reinforcing base 7.

[0039] Specifically, such as Figure 2 As shown, both the telescopic end of the electric telescopic pole 24 and the telescopic end of the auxiliary telescopic pole 25 are welded with reinforcing rings 8. The side of the reinforcing ring 8 away from the electric telescopic pole 24 and the auxiliary telescopic pole 25 is welded to the bottom of the snap ring 26.

[0040] Specifically, such as Figure 5 As shown, a fixing ring 9 is welded to the bottom of the surface of the filter tank 21, and a stabilizing column 10 is welded to the bottom of the fixing ring 9.

[0041] In this embodiment: by setting the reinforcing ring 8, the connection strength between the telescopic rod and the snap ring 26 can be enhanced, avoiding the breakage of the weld point due to long-term stress. By setting the fixing ring 9, an installation carrier is provided for the stabilizing column 10. By cooperating with the stabilizing column 10, the stability of the filter tank 21 is further enhanced. By setting the stabilizing column 10, together with the support base 1, the filter tank 21 is supported, which can distribute the force on the bottom of the filter tank 21 and avoid the welding fatigue caused by the filter tank 21 relying solely on the bottom weld point to bear the weight.

[0042] Working principle: First, the operator sets the operating parameters through the PLC controller 29. At this time, the circulating pump 32 starts working, drawing the plating solution to be filtered from the external electroplating tank through the suction pipe 33 connected on the left. Then, the circulating pump 32 pressurizes the drawn plating solution and delivers it to the inside of the connecting plate 22 through the drain pipe 31 connected on the right. The connecting plate 22 plays a preliminary guiding role for the plating solution, guiding it into the liquid inlet 27 inside the filter tank 21, preventing the plating solution from splashing or accumulating randomly in the filter tank 21. Then, the liquid inlet 27 collects the plating solution through the funnel-shaped structure and guides it to the double-layer filter ring 28 installed on the inner side. The plating solution first passes through the filter ring 28 at the top of the liquid inlet 27 to intercept large-diameter impurities, and then flows through the filter ring 28 at the bottom for further filtration of fine suspended particles. The plating solution is purified through a double-layer staged filtration system, significantly improving its purity. The purified plating solution then flows out from the inlet hopper 27 into the bottom space of the filter tank 21, and is discharged through the outlet pipe 34 fixed to the bottom of the filter tank 21. The outlet pipe 34 connects to an external return pipe, transporting the purified plating solution back to the electroplating tank. Finally, when maintenance and replacement of the filter ring 28 are required, the operator controls the electric telescopic rod 24 and auxiliary telescopic rod 25 to retract synchronously via the PLC controller 29, causing the locking ring 26 and the inlet hopper 27 to descend to the pick-up / drop-off port 4. The operator holds the handle 6 to open the sealing door 5, directly removes the inlet hopper 27 from the pick-up / drop-off port 4, replaces the internal filter ring 28, re-locks the locking ring 26, and then raises it back to its original position via the telescopic rod and closes the sealing door 5.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
