Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically an activated carbon filtration device for nickel plating solution. Background Technology

[0002] In addition to the main salt, nickel plating solutions also contain key additives such as primary brighteners, secondary brighteners, and auxiliary brighteners. During the electroplating process, the plating solution is susceptible to contamination from various factors, such as metallic impurities from anodic dissolution, dust particles from the environment, and decomposition products of brighteners under high temperatures or strong currents. These impurities can lead to defects in the plating layer, such as roughness, pinholes, and blistering, reducing the current efficiency of the solution, increasing energy consumption, and seriously affecting product quality and production efficiency. Therefore, developing efficient plating solution purification technology has become an urgent need in the electroplating industry. Activated carbon filtration devices, due to their unique adsorption performance and economic efficiency, have gradually become the core equipment for plating solution purification.

[0003] A search revealed a utility model patent with Chinese patent publication number CN214937910U, which discloses an electroplating filtration device, including an electroplating device, a power control device, and a water pump. The power control device is fixedly installed at the top left end of the electroplating device. A cathode electrode rod is electrically connected to the bottom of the power control device. A crossbar is fixedly installed at the right end of the power control device, and an anode electrode rod is installed at the bottom of the right end of the crossbar. The anode electrode rod is electrically connected to the power control device through a wire.

[0004] The above-mentioned device filters the electroplating solution by setting up a filter cartridge. When too many impurities accumulate, it takes a long time to replace the filter cartridge. If impurities are generated during this time, it may affect the electroplating quality, so the device must be stopped, which affects work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an activated carbon filtration device for nickel plating solutions to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an activated carbon filtration device for nickel plating solution, comprising a support frame and an electroplating tank. The support frame is fixedly connected to the outer wall of one side of the electroplating tank. A water supply assembly is installed between the support frame and the electroplating tank. The water supply assembly includes an electric telescopic rod fixedly connected to the top outer wall of the support frame. A support ring is fixedly connected to the output end of the electric telescopic rod. A stepper motor is fixedly installed on the bottom inner wall of the support ring. A horizontally set cover is fixedly connected to the output end of the stepper motor. A pump body is fixedly installed at the bottom of the other outer wall of the electroplating tank. The water inlet of the pump body is connected to the internal space of the electroplating tank. The same water inlet pipe is fixedly inserted between the water outlet of the pump body and the cover. Two vertically set installation chambers are installed inside the support frame, and the cover faces one of the installation chambers.

[0007] This allows the two activated carbon filter chambers to be used alternately, with a very short alternation time. This avoids the problem of excessive impurities caused by long replacement times, which helps ensure electroplating quality. When the pump starts, the electroplating solution inside the electroplating tank is pumped into the inlet pipe, and then enters the filter chamber through the cover for filtration. When the activated carbon packing in one of the filter chambers is insufficient, the electric telescopic rod at the top of the support frame is activated, and the support ring and cover are moved upward. After the cover is removed from the installation chamber, the stepper motor inside the support ring is activated, and the stepper motor drives the cover to rotate counterclockwise half a turn. The cover then moves to the top of the other installation chamber, and the electric telescopic rod drives the support ring and cover to merge with the installation chamber, so the activated carbon in the other filter chamber can continue to be used.

[0008] As a further preferred embodiment of this technical solution, a limiting plate is fixedly connected to the inner walls of both sides of the support frame. A vertically arranged groove is provided in the middle of the limiting plate. A horizontally arranged fixing tube is fixedly connected to the outer wall of one side of the cover. A positioning post is slidably inserted into the fixing tube. The same spring is fixedly connected between the fixing tube and the positioning post. The positioning post is inserted into the groove in the middle of the limiting plate.

[0009] As a further preferred embodiment of this technical solution, each of the two installation chambers is equipped with a filter assembly. The filter assembly includes a retaining ring fixedly connected to the inner circumference of the installation chamber. A filter chamber is slidably inserted inside the retaining ring. The filter chamber is completely located within the interior space of the installation chamber. A receiving mesh is provided on the bottom outer wall of the filter chamber, and activated carbon filler is filled inside the filter chamber. A water guide pipe is provided at one end of the bottom of the installation chamber, and one end of the water guide pipe extends into the electroplating tank.

[0010] As a further preferred embodiment of this technical solution, a handle is provided on the top outer wall of the filter chamber, and an avoidance hole is provided in the middle of the handle.

[0011] As a further preferred embodiment of this technical solution, a sealing ring is provided on the top of the outer circumferential wall of the filter chamber.

[0012] As a further preferred embodiment of this technical solution, the two installation chambers are fixedly fitted with the same collection hopper. The bottom wall of the collection hopper is inclined. An inclined drain pipe is installed on the outside of the collection hopper. A drain outlet is provided at the lowest point of the bottom of the collection hopper. An inclined drain pipe is fixedly connected to the drain outlet. The other end of the drain pipe extends into the electroplating tank.

[0013] As a further preferred embodiment of this technical solution, the water inlet pipe is made of steel wire flexible hose.

[0014] As a further preferred embodiment of this technical solution, two vertically arranged stabilizing rods are fixedly connected to the top outer wall of the support ring, and both stabilizing rods are slidably inserted into the support frame.

[0015] This invention provides an activated carbon filtration device for nickel plating solutions, which has the following advantages:

[0016] This invention, by setting up a water supply component and two installation chambers, allows the two activated carbon filter chambers to be used alternately. The alternation process is extremely time-efficient, avoiding the problem of excessive impurities caused by prolonged replacement time, which helps ensure electroplating quality. When the pump is started, the electroplating solution inside the electroplating tank is pumped into the inlet pipe, and then enters the filter chamber through the cover for filtration. When the activated carbon packing in one of the filter chambers is insufficient, the electric telescopic rod at the top of the support frame is activated, and the support ring and the cover are moved upward. After the cover leaves the installation chamber, the stepper motor inside the support ring is activated, and the stepper motor drives the cover to rotate counterclockwise half a turn. The cover then moves to the top of the other installation chamber, and the electric telescopic rod drives the support ring and the cover to merge with the installation chamber, so the activated carbon in the other filter chamber can continue to be used.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 4 As shown in this embodiment, an activated carbon filtration device for nickel plating solution includes a support frame 1 and an electroplating tank 2. The support frame 1 is fixedly connected to the outer wall of one side of the electroplating tank 2. A water supply component 5 is installed between the support frame 1 and the electroplating tank 2. The water supply component 5 includes an electric telescopic rod 501 fixedly connected to the top outer wall of the support frame 1. A support ring 502 is fixedly connected to the output end of the electric telescopic rod 501. A stepper motor 503 is fixedly installed on the bottom inner wall of the support ring 502. A horizontally set cover 504 is fixedly connected to the output end of the stepper motor 503. A pump body 506 is fixedly installed at the bottom of the outer wall of the other side of the electroplating tank 2. The water inlet of the pump body 506 is connected to the internal space of the electroplating tank 2. The water outlet of the pump body 506 and the cover 504 are fixedly connected by the same water inlet pipe 505. Two vertically set installation chambers 601 are installed inside the support frame 1. The cover 504 is directly opposite one of the installation chambers 601.

[0024] A limiting plate 510 is fixedly connected to the inner walls of both sides of the support frame 1. A vertically arranged groove is opened in the middle of the limiting plate 510. A horizontally arranged fixing tube 507 is fixedly connected to the outer wall of one side of the cover 504. A positioning post 508 is slidably inserted into the fixing tube 507. The same spring 509 is fixedly connected between the fixing tube 507 and the positioning post 508. The positioning post 508 is inserted into the groove in the middle of the limiting plate 510.

[0025] When pump body 506 starts, the electroplating solution inside electroplating tank 2 is pumped into inlet pipe 505, and then enters filter chamber 603 through cover 504 for filtration. When the activated carbon packing in one of the filter chambers 603 is insufficient, the electric telescopic rod 501 at the top of support frame 1 is activated, and support ring 502 and cover 504 are moved upward. After cover 504 is disengaged from installation chamber 601, stepper motor 503 inside support ring 502 is activated. Stepper motor 503 drives cover 504 to rotate counterclockwise half a turn, and cover 504 will move to the top of the other installation chamber 601. The electric telescopic rod 501 drives the support ring 1 to rotate counterclockwise half a turn. The support ring 502 and the cover 504 are combined with the installation chamber 601, and the activated carbon inside the other filter chamber 603 can continue to be used. During the replacement of the cover 504, the cover 504 drives the positioning post 508 to contact the side of the limiting plate 510 through the fixing tube 507. The positioning post 508 is squeezed back to the fixing tube 507, and the spring 509 is also compressed. After the position of the cover 504 is adjusted, the spring 509 will push the positioning post 508 into the groove in the middle of the limiting plate 510, which can achieve the positioning effect, so that the subsequent docking process between the cover 504 and the installation chamber 601 can be carried out smoothly.

[0026] like Figure 2 and Figure 3 As shown, each of the two installation chambers 601 has a filter assembly 6 installed inside. The filter assembly 6 includes a retaining ring 604 fixedly connected to the inner circumference of the installation chamber 601. A filter chamber 603 is slidably inserted inside the retaining ring 604. The filter chamber 603 is completely inside the installation chamber 601. A receiving mesh is provided on the bottom outer wall of the filter chamber 603, and the filter chamber 603 is filled with activated carbon filler. A water guide pipe 602 is provided at one bottom end of the installation chamber 601, and one bottom end of the water guide pipe 602 extends into the electroplating tank 2.

[0027] During filtration, the space formed by the cover 504 and the installation chamber 601 is a closed space. Under the action of water pressure, the flow rate of the electroplating solution can be accelerated. Then, it is introduced into the electroplating tank 2 through the water pipe 602 from the bottom opening. When replacing the activated carbon packing inside the filter chamber 603, the handle can be grabbed and pulled upwards, and the filter chamber 603 can be quickly removed.

[0028] like Figure 2 and Figure 3 As shown, a handle is provided on the top outer wall of the filter chamber 603, and an avoidance hole 605 is provided in the middle of the handle. This makes it convenient to take the filter chamber 603, while allowing the electroplating solution to pass through the avoidance hole 605, thus preventing the electroplating solution from falling onto the handle.

[0029] like Figure 3As shown, a sealing ring 606 is provided on the top of the outer circumference of the filter chamber 603, which helps to improve the airtightness between the filter chamber 603 and the installation chamber 601 and prevents the electroplating solution from passing directly through the gap.

[0030] like Figure 1 and Figure 2 As shown, the two installation chambers 601 are fixedly fitted with the same collection hopper 3. The bottom wall of the collection hopper 3 is inclined. An inclined drain pipe 4 is installed on the outside of the collection hopper 3. A drain outlet is provided at the lowest point of the bottom of the collection hopper 3. An inclined drain pipe 4 is fixedly connected to the drain outlet. The other end of the drain pipe 4 extends into the electroplating tank 2. When the cover 504 is rotated, the electroplating solution will enter the inside of the collection hopper 3 and then enter the electroplating tank along the collection hopper 4, which can prevent leakage of the electroplating solution when changing the work.

[0031] like Figure 1 As shown, the water inlet pipe 505 is made of steel wire hose, which allows the electroplating solution to flow normally while preventing it from affecting the rotation of the cap 504.

[0032] like Figure 1 and Figure 2 As shown, two vertically arranged stabilizing rods are fixedly connected to the top outer wall of the support ring 502, and both stabilizing rods are slidably inserted into the support frame 1, which helps to improve the stability of the support ring 502.

[0033] This utility model provides an activated carbon filtration device for nickel plating solutions, the specific working principle of which is as follows:

[0034] When the device is working, the pump body 506 starts, and the electroplating solution inside the electroplating tank 2 is pumped into the inlet pipe 505. It then passes through the cover 504 into the filter chamber 603 for filtration. When the activated carbon packing in one of the filter chambers 603 becomes insufficient, the electric telescopic rod 501 at the top of the support frame 1 is activated. The support ring 502 and the cover 504 are moved upwards. After the cover 504 detaches from the mounting chamber 601, the stepper motor 503 inside the support ring 502 is activated. The stepper motor 503 drives the cover 504 to rotate counterclockwise half a turn, causing the cover 504 to move directly above the other mounting chamber 601. The electric telescopic rod 501... The support ring 502 and the cover 504 are driven to merge with the installation chamber 601, so that the activated carbon in the other filter chamber 603 can continue to be used. During the replacement of the cover 504, the cover 504 drives the positioning post 508 to contact the side of the limiting plate 510 through the fixing tube 507. The positioning post 508 is squeezed back to the fixing tube 507, and the spring 509 is also compressed. When the position of the cover 504 is adjusted, the spring 509 will push the positioning post 508 into the groove in the middle of the limiting plate 510, which can achieve the positioning effect, so that the subsequent docking process between the cover 504 and the installation chamber 601 can be carried out smoothly. During filtration, the space formed by the cover 504 and the installation chamber 601 is a closed space. Under the action of water pressure, the flow rate of the electroplating solution can be accelerated. Then, it is introduced into the electroplating tank 2 through the water pipe 602 from the bottom opening. When replacing the activated carbon packing inside the filter chamber 603, the handle can be grabbed and pulled upwards, and the filter chamber 603 can be quickly removed.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
