Description

TECHNICAL FIELD

[0001] The utility model relates to electroplating technical field especially is related to a mobile electroplating solution filtering device. BACKGROUND

[0002] In the electroplating industry, some auxiliary additives such as brightener, leveling agent, wetting agent, stress reliever, complexing agent, dispersant, stabilizer and buffer are often added in the electroplating bath according to specific product requirements. However, the additives may decompose during electrolysis, thereby generating small-molecule organic compounds, which can reduce the stability of the electroplating solution and cause pinholes, pitting or brittleness in the plating layer. Therefore, the concentration of small-molecule organic compounds in the electroplating bath needs to be monitored, and the electroplating solution needs to be filtered to reduce the concentration of small-molecule organic compounds when the concentration of small-molecule organic compounds is too high. For example, the electroplating bath is regularly subjected to small-molecule organic compound filtration treatment.

[0003] For small-molecule organic compound filtration treatment of the electroplating bath, the conventional method is to embed a liquid pump and a carbon rod in the electroplating bath, form a circulating liquid flow by the liquid pump, and make the liquid flow through the carbon rod continuously to adsorb small-molecule organic compounds on the surface of the carbon rod. However, this conventional method has the following disadvantages:

[0004] 1. The adsorption area of the carbon rod is small, and the removal efficiency of small-molecule organic compounds is low.

[0005] 2. The manufacturer usually has multiple electroplating production lines, and each electroplating production line is provided with multiple electroplating baths. Each electroplating bath needs to be provided with a small-molecule organic compound removal device composed of a liquid pump and a carbon rod, which results in high equipment cost.

[0043] like Figures 1 to 7 As shown, it is a mobile electroplating solution filtration device 100 according to one embodiment of the present invention.

[0044] like Figure 1 and Figure 2As shown, the mobile electroplating solution filtering device 100 comprises a movable platform 10, a liquid pump 20 installed on the movable platform 10, an organic matter filter 30 installed on the movable platform 10, an activated carbon filter 40 installed on the movable platform 10, a liquid inlet hose 50 connected to the liquid pump 20, and a liquid outlet hose 60 connected to the activated carbon filter 40. The movable platform 10 is movable and used as a mobile platform. The liquid pump 20 is used to provide driving force for the electroplating solution flow. The organic matter filter 30 is used to adsorb small-molecule organic matters in the electroplating solution by activated carbon. The activated carbon filter 40 is used to intercept activated carbon escaping from the organic matter filter 30 to avoid the activated carbon flowing into the electroplating solution tank. The liquid inlet hose 50 is used to connect to the electroplating solution tank to introduce the electroplating solution. The liquid outlet hose 60 is used to connect to the electroplating solution tank to return the filtered electroplating solution to the electroplating solution tank.

[0045] Hereinafter, the mobile electroplating solution filtering device 100 will be further described in combination with Figures 1 to 7 As shown, the mobile electroplating solution filtering device 100 comprises a movable platform 10, a liquid pump 20 installed on the movable platform 10, an organic matter filter 30 installed on the movable platform 10, an activated carbon filter 40 installed on the movable platform 10, a liquid inlet hose 50 connected to the liquid pump 20, and a liquid outlet hose 60 connected to the activated carbon filter 40. The movable platform 10 is movable and used as a mobile platform. The liquid pump 20 is used to provide driving force for the electroplating solution flow. The organic matter filter 30 is used to adsorb small-molecule organic matters in the electroplating solution by activated carbon. The activated carbon filter 40 is used to intercept activated carbon escaping from the organic matter filter 30 to avoid the activated carbon flowing into the electroplating solution tank. The liquid inlet hose 50 is used to connect to the electroplating solution tank to introduce the electroplating solution. The liquid outlet hose 60 is used to connect to the electroplating solution tank to return the filtered electroplating solution to the electroplating solution tank.

[0046] As shown in Figure 1 and Figure 2 The bottom of the movable platform 10 is provided with a roller 11. For example, in the embodiment, the movable platform 10 comprises a flat car 12 and a storage rack 13 installed on the flat car 12. The roller 11 is located at the bottom of the flat car 12, and the roller 11 can also be provided with brake pads. The liquid pump 20, the organic matter filter 30, and the activated carbon filter 40 are all installed on the storage rack 13. The combination of the flat car 12 and the storage rack 13 can constitute a simple and low-cost movable platform 10.

[0047] Further, in order to play a role of preventing mistakes, as shown in Figure 1 In the embodiment, the storage rack 13 is provided with a liquid flow direction mark 131. The liquid flow direction mark 131 facilitates the operator to quickly identify the liquid flow direction and reduces the risk of incorrect installation of the filter element when assembling the equipment. For example, in the embodiment, arrow marks are provided on the top of the storage rack 13 to indicate the flow direction of the liquid.

[0048] As shown in Figure 1 and Figure 2 In the embodiment, the liquid pump 20 is fixed on the lower layer of the storage rack 13, while the organic matter filter 30 and the activated carbon filter 40 are fixed on the upper layer of the storage rack 13. The staggered arrangement provides layout space for the pipelines between the liquid pump 20, the organic matter filter 30, and the activated carbon filter 40, and improves the installation compactness of the equipment.

[0049] In combination with Figure 1 and Figure 4The organic filter 30 includes: a first filter body 31 located on the stage 10, a filter bag 32 housed within the first filter body 31, and activated carbon blocks (not shown) loaded in the filter bag 32. The inlet of the first filter body 31 is connected to the outlet of the liquid pump 20. Multiple activated carbon blocks are stacked within the filter bag 32.

[0050] Furthermore, in this embodiment, the activated carbon block is in the form of fragments, resulting in high adsorption efficiency and low cost. In other embodiments, the activated carbon block can also be in powder form, offering even higher adsorption efficiency, but at a higher cost compared to fragments. Both fragmented and powdered activated carbon have a large adsorption area, effectively improving the removal efficiency of small molecule organic matter.

[0051] Combination Figure 1 and Figure 6 As shown, the activated carbon filter 40 includes: a second filter body 41 located on the stage 10, an inner support 42 housed within the second filter body 41, and filter paper 43 passing through the inner support 42. The inlet of the second filter body 41 is connected to the outlet of the first filter body 31. Multiple sheets of filter paper 43 are sequentially passed through the inner support 42 along the axial direction of the second filter body 41. Figure 6 (To facilitate clear demonstration, the thickness of filter paper 43 has been increased).

[0052] Furthermore, in this embodiment, such as Figure 3 As shown, both the organic filter 30 and the activated carbon filter 40 are bag filters. Bag filters have a simple structure, low cost, and easy filter element replacement, making operation simple. For example, in this embodiment, the filter bag 32 is detachably snapped onto the inner wall of the first filter body 31, while the inner support 42 is detachably placed in the second filter body 41. After opening the top flap of the first filter body 31, the filter bag 32 can be pulled upwards. Similarly, after opening the top flap of the second filter body 41, the inner support 42 can be pulled upwards.

[0053] Furthermore, improvements can be made based on the bag filter design.

[0054] For example, such as Figure 5 As shown, in this embodiment, the filter bag 32 is provided with a handle 321 at the top. The handle 321 facilitates the loading or replacement of activated carbon by the operator.

[0055] For example, such as Figure 6 and Figure 7As shown, the inner support 42 comprises a tray 421 and a middle shaft 422 connecting the tray 421. The tray 421 is used to support the filter paper 43. The middle shaft 422 is used to pass through the filter paper 43. The filter paper 43 is stacked in a puncture manner. The assembly is simple and the filtering efficiency is high.

[0056] Further, in other embodiments, the inner support 42 can further comprise a pull ring detachably connected to the top of the middle shaft 422. When the filter paper 43 needs to be loaded or replaced, the pull ring can be installed to easily move the inner support 42. In addition, when the filter paper 43 needs to be passed through the middle shaft 422, the pull ring can be detached to avoid hindering the passing of the filter paper 43.

[0057] As shown in Figure 1 and Figure 2 , one end of the liquid inlet hose 50 is connected to the liquid inlet of the liquid pump 20, and the other end of the liquid inlet hose 50 is a liquid suction port for being placed into the electroplating tank.

[0058] As shown in Figure 1 and Figure 2 , one end of the liquid outlet hose 60 is connected to the liquid outlet of the second filter body 41, and the other end of the liquid outlet hose 60 is a liquid discharge port for being placed into the electroplating tank.

[0059] Working principle:

[0060] As shown in Figure 1 and Figure 2 , when the electroplating tank needs to be filtered, the mobile stage 10 is moved to the electroplating tank. Then, one end of the liquid inlet hose 50 is placed into the electroplating tank, and the other end of the liquid outlet hose 60 is placed into the electroplating tank. Next, the liquid pump 20 is started, so that the electroplating liquid in the electroplating tank is sucked into the liquid inlet hose 50, the electroplating liquid is first adsorbed by the activated carbon block in the organic matter filter 30 (see Figure 4 , the electroplating liquid flows from top to bottom through the activated carbon), then the filter paper 43 of the activated carbon filter 40 intercepts the activated carbon debris escaping from the organic matter filter 30 (see Figure 6 , the electroplating liquid flows from top to bottom through the filter paper 43), and finally the electroplating liquid is returned to the electroplating tank through the liquid outlet hose 60. When the organic matter adsorption treatment of one electroplating tank is completed, the mobile electroplating liquid filtering device 100 can be transferred to the next electroplating tank to be filtered. One device can complete the filtering treatment of the electroplating tanks of a production line or even multiple production lines.

[0061] In use, the mobile electroplating solution filtering device 100 only needs to be moved to the electroplating solution tank that needs to be filtered, so the length of the liquid inlet hose 50 and the liquid outlet hose 60 needs to be short, in work, the electroplating solution flows out of the electroplating solution tank along a short path, the flow rate of the electroplating solution is fast, and the work efficiency is high. Moreover, since the electroplating solution flows out of the electroplating solution tank along a short path, the influence of the liquid level drop in the electroplating solution tank is small, and in some cases, the electroplating operation can be used without stopping.

[0062] The mobile electroplating solution filtering device 100 described above adopts a mobile platform design, when the electroplating solution tank needs to be filtered for small molecules of organic matter, the filtering device is moved to the electroplating solution tank, and then activated carbon blocks are used to adsorb small molecules of organic matter, the surface area of the activated carbon blocks is larger than that of carbon rods, the adsorption area is larger, the removal efficiency of small molecules of organic matter is effectively improved, and the mobile design can realize that one filtering device meets the needs of small molecules of organic matter filtering of multiple electroplating solution tanks, and greatly reduces the equipment cost.

[0063] The technical features of the above embodiments can be combined in any manner, in order to make the description concise, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the description.

[0064] The above embodiments only express the preferred implementation of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
