Description

Technical Field

[0001] This utility model relates to the technical field of diamond wire production equipment, and in particular to an activated carbon powder pressure filter device for diamond wire electroplating solution. Background Technology

[0002] Diamond wire is short for diamond cutting wire, also known as diamond cutting wire or diamond wire. Many hard materials in industry are cut using cutting steel wire or even higher-quality diamond wire, such as polycrystalline silicon wafers, monocrystalline silicon, and crystal rods in the photovoltaic field. In diamond wire production lines, whether it's electroless nickel plating of diamond micron powder or electroplating of diamond micron powder onto the diamond wire busbar, an electroplating solution is required.

[0003] The electroplating solution is a nickel sulfamate solution. After a period of use, organic impurities are introduced into the solution through the busbar and the diamond micropowder used for plating. When these organic impurities accumulate to a certain level, they weaken the adhesion of the diamond wire coating. Therefore, it is necessary to periodically transfer the electroplating solution from the electroplating tank to a stirring tank and add activated carbon powder to adsorb and treat the residual organic impurities. Utility model patent CN218280852U discloses a filter press, which uses a filter press to separate activated carbon from the liquid. However, this utility model's technical solution is the same as existing solutions, both using a large filter press tank for centralized treatment of the electroplating solution. In actual production, there are often two or more production lines operating in parallel, with multiple electroplating tanks far apart. Centralized treatment would require laying long pipelines and increase the pump load, making it uneconomical.

[0004] Therefore, it is necessary to develop an activated carbon powder pressure filter for diamond wire electroplating solution to address the above-mentioned defects. Utility Model Content

[0005] The purpose of this invention is to provide an activated carbon powder pressure filter for diamond wire electroplating solution, which can be flexibly positioned next to the electroplating tank for local pressure filtration, without the need for laying pipelines for centralized collection, and has good economic operation.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0017] Furthermore, an annular sealing groove is provided on the top wall of the lower tank top flange and a second sealing ring is installed thereon. The second sealing ring seals the gap between the lower tank top flange and the upper tank bottom flange.

[0018] Furthermore, the filter membrane assembly includes a support plate and a filter membrane. The inner side wall of the lower tank is provided with an inwardly protruding inner support platform. The support plate is disposed on the inner support platform, and the filter membrane is stacked on the top surface of the support plate.

[0019] Furthermore, the filter membrane is specifically made of 100-mesh nylon material, and the diameter of the filter pores is smaller than the diameter of the activated carbon powder.

[0020] The key innovation of this application lies in selecting a suitable filter membrane, which can effectively filter activated carbon powder and can also be reused after rinsing, thus reducing the cost of use.

[0021] Furthermore, the filter membrane assembly also includes a handle, the threaded rod segment at the base of the handle being threadedly connected to the central threaded hole of the frustum in the middle of the bearing plate.

[0030] The core of this utility model is to provide an activated carbon powder pressure filter device for diamond wire electroplating solution, which can be flexibly positioned next to the electroplating tank for local pressure filtration, without the need for laying pipelines for centralized collection, and has good economic operation.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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.

[0032] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] In one specific implementation, such as Figure 1 and Figure 2 As shown, the activated carbon powder pressure filter device of this utility model is used to remove activated carbon powder from diamond wire electroplating solution, and includes:

[0034] The mobile trolley 1, in the form of a flatbed cart, is used to carry the transfer pump 2 and the filter press assembly. The transfer pump 2 is mounted to the top surface of the main plate of the mobile trolley 1 via bolts to the bottom seat plate, and the filter press assembly is also fixed to the top surface of the main plate of the mobile trolley 1. The bottom of the main plate of the mobile trolley 1 is equipped with wheels 101, which can flexibly position it in the working position.

[0035] The infusion pipeline 3, made of 1 / 4-inch plastic tubing, connects the output port of the delivery pump 2 and the inlet of the filter press assembly. A third valve 4, specifically a sanitary stainless steel ball valve, is connected in series at the inlet of the filter press assembly, offering excellent corrosion resistance. A suction hose for drawing the electroplating solution from the mixing tank is connected to the inlet of the delivery pump 2; an output hose for discharging the filtered electroplating solution is connected to the bottom of the filter press assembly; both the suction hose and the output hose are made of PVC steel wire spiral reinforced tubing, providing strong compressive strength.

[0036] An air intake assembly is disposed at the top of the filter press assembly and is capable of filling the liquid storage chamber of the filter press assembly with compressed air, which pressurizes the electroplating solution in the liquid storage chamber to pass through the filter unit in the filter press assembly.

[0037] By integrating the delivery pump 2, the liquid delivery pipeline 3, and the filter press assembly onto the mobile trolley 1, the working location can be easily switched between different diamond wire production lines. A single device can treat all locations on all diamond wire production lines for the removal of activated carbon powder from the electroplating solution. By adding a third valve 4 to the inlet of the filter press assembly, the inlet can be sealed during the aeration process, preventing compressed air from flowing back into the delivery pump 2. This invention provides an activated carbon powder filter press for diamond wire electroplating solutions. It can be flexibly positioned next to the electroplating tank for on-site filter press treatment, eliminating the need for centralized collection pipelines, resulting in economical operation.

[0038] In one specific embodiment of this utility model, such as Figure 1 As shown, there are four bottom wheels 101, which are respectively located at the four corners of the bottom surface of the main plate of the mobile trolley 1. Two bottom wheels 101 at one end are set as omnidirectional wheels, and two bottom wheels 101 at the other end are set as directional wheels. The two directional wheels have a parking brake function.

[0039] Specifically, such as Figure 1 As shown, the activated carbon powder pressure filter device for diamond wire electroplating solution of this utility model also includes a handrail 102, which is set on the top surface of the main plate of the mobile trolley 1 and located at one end near the pressure filter tank assembly.

[0040] By reasonably setting four bottom wheels 101 at the four corners of the bottom surface of the main plate of the mobile trolley 1, including two omnidirectional wheels, it can turn flexibly. With the addition of the handrail 102, it is convenient for operators to push and pull to any working position to carry out filter pressing operations.

[0041] In one specific embodiment of this utility model, such as Figure 1 As shown, the air intake assembly includes an air pipe connector 601, an air intake valve 10, and an exhaust valve 11. The base of the air pipe connector 601 is connected to the top of the filter press assembly. The air pipe connector 601 is connected to the air intake valve 10 and the exhaust valve 11, respectively. The other end of the air intake valve 10 is provided with a quick connector for connecting an air pipe, which is connected to a compressed air supply unit. The compressed air supply unit can be an air pump or a spare interface air line for production line equipment.

[0042] Specifically, as shown in the figure, the air intake assembly also includes a pressure gauge 12 and a muffler. The pressure gauge 12 for displaying air pressure is installed at the top of the air pipe connector 601, and the air intake valve 10 and the exhaust valve 11 are respectively installed on the side wall of the air pipe connector 601. The muffler is installed at the other end of the exhaust valve 11.

[0043] By adding an intake valve 10 and an exhaust valve 11 to the air pipe connector 601, controllable air intake and exhaust can be achieved. A quick-connect fitting for the air pipe at the other end of the intake valve 10 allows for convenient connection to a compressed air supply unit. Adding a pressure gauge 12 enables real-time monitoring of the liquid storage chamber of the filter press assembly, preventing overpressure and underpressure. Adding a silencer reduces exhaust noise.

[0044] In one specific embodiment of this utility model, such as Figure 1 As shown, a first valve 201 is connected in series at the inlet end of the transfer pump 2, and a second valve 301 is connected in series on the infusion pipeline 3. An output pipe connector 704 is provided at the bottom output port of the filter press assembly, and a fourth valve 8 is connected in series on the output pipe connector 704. The first valve 201, the second valve 301, and the fourth valve 8 are all ball valves.

[0045] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the filter press assembly includes an upper tank 6, a lower tank 7, and a filter membrane assembly. The upper tank 6 and the lower tank 7 are vertically coaxial and interlocked, connected by quick-connect bolts 9 on the end flanges, with four sets of quick-connect bolts 9 evenly distributed around the circumference. The bottom wall of the lower tank 7 is mounted to the main plate of the mobile trolley 1 via multiple support legs 703. The filter membrane assembly is located at the top of the lower tank 7 and is capable of filtering the electroplating solution; the filter membrane assembly is also known as the filtration unit.

[0046] Specifically, such as Figure 1 and Figure 2 As shown, a lug 702 is provided on the outer wall of the top flange of the lower tank body 7. The shaft 901 at the root of the quick-connect bolt 9 is rotatably connected to the end hole of the lug 702. The root of the threaded rod of the quick-connect bolt 9 is vertically welded to the middle position of the shaft 901. A claw 603 is provided on the outer wall of the bottom flange of the upper tank body 6. A lock nut is threaded onto the quick-connect bolt 9, and the lock nut can be pressed onto the claw 603.

[0047] Specifically, such as Figure 1 and Figure 2 As shown, the groove in the middle of the chuck 603 can accommodate the threaded rod of the quick-connect bolt 9.

[0048] Specifically, such as Figure 1 and Figure 2 As shown, a handle 602 is also provided on the outer side wall of the upper tank 6, and two handles 602 are symmetrically arranged on the outer side wall of the upper tank 6. The top of the third valve 4 is connected to the end of the infusion pipeline 3 through a quick-connect clamp 5.

[0049] Specifically, such as Figure 2As shown, a circular sealing groove is coaxially provided on the top wall of the top flange of the lower tank body 7 and a second sealing ring 17 is installed thereon. The second sealing ring 17 seals the gap between the top flange of the lower tank body 7 and the bottom flange of the upper tank body 6.

[0050] The upper tank 6 and lower tank 7 are connected by four sets of quick-connect bolts 9, and can be quickly disassembled and installed using a handle 602 and quick-release clamps 5. The filter membrane assembly is located on the top of the lower tank 7 for easy disassembly and replacement. A second sealing ring 17 is added to prevent leakage at the joints.

[0051] In one specific embodiment of this utility model, such as Figure 2 As shown, the filter membrane assembly includes a support plate 14 and a filter membrane 16, with micropores evenly distributed on the support plate 14. An inwardly protruding inner support platform 701 is provided on the top of the inner wall of the lower tank 7, and the support plate 14 is disposed on the inner support platform 701, with the filter membrane 16 stacked on the top surface of the support plate 14.

[0052] Specifically, such as Figure 2 As shown, a sealing ring groove is provided on the top surface of the inner support 701 and a first sealing ring 13 is installed thereon. The edge of the bearing plate 14 is pressed onto the first sealing ring 13, which reduces the leakage of electroplating liquid in this gap.

[0053] It should be noted that very low-mesh activated carbon powder is used to remove organic impurities from the electroplating solution. A certain amount of activated carbon powder is added according to the volume of the electroplating solution in the stirring tank and stirred for two hours. After the activated carbon powder has fully adsorbed the organic impurities, it needs to be filtered out. Because the activated carbon powder has a very low mesh size, that is, a small particle size, it is not cleaned properly by traditional filters. Moreover, when using low-mesh filter cartridges, filters are very prone to clogging, resulting in incomplete filtration, frequent filter cartridge replacements, high costs, and extremely low filtration efficiency, making it unsuitable for batch operations. Therefore, in this utility model, if... Figure 2 As shown, the filter membrane 16 is specifically made of 100-mesh nylon material, and the diameter of the filter pores of the filter membrane 16 is smaller than the diameter of the activated carbon powder.

[0054] By using a suitable filter membrane 16 to filter the electroplating solution under pressure, activated carbon powder can be effectively removed, and the solution can be rinsed and reused.

[0055] Specifically, such as Figure 2 As shown, the filter membrane assembly also includes a handle 15, which is specifically T-shaped. A threaded section is provided at the base of the handle 15, and this threaded section is threaded into the central threaded hole of the frustum-shaped section in the bearing plate 14. The filter membrane 16 has a through-hole at the base of the handle 15.

[0056] Specifically, such as Figure 2As shown, the handle 15 is made of stainless steel or plastic and is usually immersed in electroplating solution.

[0057] By adding a handle 15, it is easy to remove the carrier plate 14, and then remove the entire filter membrane 16 and activated carbon powder filter cake, making the replacement of the filter membrane 16 very convenient.

[0058] The working process of this utility model for the activated carbon powder pressure filter in diamond wire electroplating solution is as follows: First, close the inlet valve 10 and open the exhaust valve 11 to allow residual compressed air between the upper tank 6 and the filter membrane assembly to be smoothly discharged through the air pipe joint 601, exhaust valve 11, and the silencer, making the air pressure inside the tank the same as atmospheric pressure. Open the first valve 201, the second valve 301, and the third valve 4, and connect the liquid extraction hose at the inlet end of the delivery pump 2 to the bottom of the stirring tank. Start the delivery pump 2 to deliver the plating solution containing activated carbon powder into the pressure filter assembly. When bubbles are felt at the exhaust valve 11, it indicates that the liquid level in the pressure filter assembly has reached the specified height. Stop the delivery pump 2 and close the exhaust valve 11 and the third valve 4. Open the fourth valve 8 and the inlet valve 10 to supply compressed air from the compressed air supply unit. Reduce the pressure to about 4 kg using the pressure reducing valve, and deliver the compressed air into the pressure filter assembly through the air pipe. Under air pressure, the electroplating solution passes through the filter membrane 16 at the top of the upper tank 6 and is discharged into a temporary storage container via the output connector 704 at the bottom of the device. When the flow rate of the electroplating solution at the output connector 704 slowly decreases and bubbles appear, it indicates that the electroplating liquid pressure filtration in the pressure filter assembly is complete. Then, the inlet valve 10 and the fourth valve 8 are closed again, and the exhaust valve 11 is slowly opened to exhaust the air. The same process is repeated for the next cycle until all the electroplating solution in the mixing tank has been processed.

[0059] In summary, this utility model, an activated carbon powder pressure filter for diamond wire electroplating solution, integrates the delivery pump 2, the liquid delivery pipeline 3, and the pressure filter tank assembly onto a mobile trolley 1. This allows for convenient switching of work locations between different diamond wire production lines, enabling the removal of activated carbon powder from electroplating solutions in all locations across all diamond wire production lines using a single device. By adding a third valve 4 to the inlet of the pressure filter tank assembly, the inlet can be sealed during the air filling process, preventing compressed air from flowing back into the delivery pump 2. This activated carbon powder pressure filter for diamond wire electroplating solution can be flexibly positioned next to the electroplating tank for on-site pressure filtration, eliminating the need for centralized collection pipelines and resulting in economical operation. Furthermore, the four bottom wheels 101 strategically placed at the four corners of the main platform of the mobile trolley 1, including two omnidirectional wheels, allow for flexible steering. Combined with the added handrail 102, this facilitates easy movement by operators to any work position for pressure filtration. By adding an inlet valve 10 and an exhaust valve 11 to the air pipe connector 601, controllable air intake and exhaust can be achieved. A quick-connect fitting for the air pipe at the other end of the inlet valve 10 allows for convenient connection to a compressed air supply unit. Adding a pressure gauge 12 enables real-time monitoring of the liquid storage chamber of the filter press assembly, preventing overpressure and underpressure. Adding a silencer reduces exhaust noise. Four sets of quick-connect bolts 9 connect the upper tank 6 and lower tank 7, which are interlocked, and the handle 602 and quick-release clamps 5 allow for quick disassembly and installation. The filter membrane assembly is located on the top of the lower tank 7 for easy disassembly and replacement. Adding a second sealing ring 17 prevents leakage at the joints. Using a suitable filter membrane 16 for pressurized filtration of the electroplating solution effectively removes activated carbon powder and allows for rinsing and reuse. By adding a handle 15, it is easy to remove the carrier plate 14, and then remove the entire filter membrane 16 and activated carbon powder filter cake, making the replacement of the filter membrane 16 very convenient.
