Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a structure for a chemical nickel filter. Background Technology

[0002] During the electroless nickel plating (EN) process, the plating solution continuously generates byproducts such as phosphites and sodium sulfate. At the same time, due to fluctuations in the stability of the plating solution, fine nickel particles are also generated. If these solid impurities are not removed in time, they will become autocatalytic nuclei, causing the plating solution to decompose in areas other than the surface of the workpiece. This will not only cause the plating solution to be scrapped and the plating quality to decline significantly, but also cause production costs to soar. As a key piece of equipment in the electroless nickel plating system, the filter's core function is to continuously intercept and remove solid impurities in the plating solution, thereby stabilizing the performance of the plating solution, extending the service life of the plating solution, and ensuring the quality of the plating coating.

[0003] Currently, filters used in electroless nickel plating processes require vertical pumps for plating solution delivery. However, vertical pumps lack self-priming capability, and their normal operation depends on the liquid level submerging the impeller. Due to the existing filter frame structure design and pump height parameters, there is a fixed minimum liquid level threshold during operation. However, in actual industrial applications, some users have installation and usage requirements at even lower liquid levels. The existing filter structure design cannot meet the requirements of such scenarios, resulting in limited equipment applicability and difficulty in matching diverse on-site installation conditions. Therefore, we need to propose an electroless nickel plating filter structure. Utility Model Content

[0004] The purpose of this utility model is to provide a structure for a chemical nickel filter. By setting a pipeline modification mechanism at the bottom of the pump mechanism and cooperating with the design of the bend joint and connecting pipe, the traditional pipeline structure is changed, which achieves the effects of reducing the minimum operating liquid level of the equipment, adapting to low liquid level scenarios, breaking the limitations of the existing structure, and improving the adaptability to industrial sites, so as to solve the problems mentioned in the background art.

[0016] 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.

[0017] Please see Figure 1-4 This utility model provides a technical solution: A chemical nickel filter structure includes a frame 1, on the top of which a filter mechanism 2 for filtering out fine nickel particles is fixedly connected. By setting the filter mechanism 2 and fixing it to the top of the frame 1, a stable filtration space can be provided for the plating solution, achieving the effect of efficiently intercepting solid impurities and ensuring the purity of the plating solution. The fixing method uses bolt fastening, which can effectively avoid the connection loosening caused by equipment vibration during the filtration process and ensure that the filtration operation is continuous and stable.

[0018] The top end of the connecting pipe 3 is connected to the inlet end of the filter mechanism 2 through the elbow joint 4. By setting the elbow joint 4, the connecting pipe 3 and the filter mechanism 2 can be flexibly connected, which can adapt to the pipeline route, reduce installation interference, and improve the connection sealing performance. The elbow joint 4 is made of corrosion-resistant engineering plastic material, and the inner wall is smooth and not easy to adhere to impurities, which can reduce the flow resistance of the plating solution. At the same time, its sealing surface adopts a stepped design to further enhance the anti-leakage performance.

[0019] The pump mechanism 5 is mounted on the frame 1, and the bottom of the pump mechanism 5 is equipped with a pipeline modification mechanism 6 for lowering the liquid level to meet the user's installation needs. The bottom of the elbow joint 4 is connected to the outlet of the pipeline modification mechanism 6 through the same elbow joint 4. By setting the pipeline modification mechanism 6 and cooperating with the connection method of the double elbow joint 4, the traditional pipeline layout is changed, so as to lower the minimum operating liquid level of the equipment and adapt to low liquid level installation scenarios. The combination angle of the double elbow joint 4 can be finely adjusted according to the site space, making the pipeline layout more flexible and adaptable to different installation environments.

[0020] In this embodiment, the pumping mechanism 5 includes a motor 501, a pump 502, and a pump inlet 503. The motor 501 is fixedly connected to the top of the frame 1 via a mounting bracket 504, and the bottom of the motor 501 is connected to the pump 502. The pump inlet 503 is located at the bottom of the pump 502. By setting the mounting bracket 504, a stable connection between the motor 501 and the frame 1 is achieved. At the same time, setting the pump inlet 503 at the bottom of the pump 502 ensures the stability of power transmission and optimizes the pipeline connection position. The bottom of the mounting bracket 504 is provided with shock-absorbing pads, which can absorb the vibration generated by the motor 501 during operation, reduce the impact on the frame 1 and other components, and extend the overall service life of the equipment.

[0021] Furthermore, it also includes a mounting plate 505, which is fixedly connected to the top of the motor 501. A pump waterproof cover 506 is fixedly bolted to the top of the mounting plate 505. By setting the mounting plate 505 as the mounting carrier for the pump waterproof cover 506 and using a bolted fixing method, the waterproof cover can be easily disassembled and installed, effectively protecting the core components of the motor 501 and the pump 502 and preventing chemical corrosion. The pump waterproof cover 506 is made of transparent material, which allows operators to directly observe the operating status of the motor 501 and the pump 502. Its edges are equipped with sealing strips to prevent plating solution vapor and splashed chemicals from entering the interior.

[0022] It is worth noting that a plug is provided on the outer wall of pump 502. By using the plug to seal the reserved interface on the outer wall of pump 502, the effects of preventing plating solution leakage, ensuring the internal sealing environment of pump 502, and maintaining normal working pressure are achieved. The connection between the plug and pump 502 adopts a threaded sealing structure. When used with sealing tape, a reliable seal can be achieved. At the same time, the plug is made of the same corrosion-resistant metal material as pump 502 to avoid electrochemical corrosion caused by material differences.

[0023] In this embodiment, the pipeline modification mechanism 6 includes a longitudinally arranged stainless steel elbow 601, an interface flange 602, and an inlet flange 603. The top of the stainless steel elbow 601 is connected to the pump inlet 503 through the interface flange 602. The inlet flange 603 is located on the raw liquid inlet of the stainless steel elbow 601. By setting the longitudinally arranged stainless steel elbow 601 in conjunction with the connection structure of the interface flange 602 and the inlet flange 603, the pipeline routing is optimized, the liquid level is reduced, and the connection strength and sealing performance are improved. The stainless steel elbow 601 is made of 304 stainless steel, which can withstand the corrosion of chemical nickel plating solution. The flange connection surface is provided with a sealing gasket, and the bolts are tightened evenly to ensure that there is no leakage at the connection.

[0024] Furthermore, a chemical addition tank 8 is fixedly connected to the outer wall of the stainless steel elbow 601. By setting up the chemical addition tank 8 and connecting it to the stainless steel elbow 601, the effects of conveniently adding chemicals to the plating solution, adjusting the composition of the plating solution in real time, and improving the stability of the plating solution can be achieved. The bottom of the chemical addition tank 8 is equipped with a flow control valve, which can accurately control the amount of chemicals added according to the plating solution detection results, so as to avoid the impact of excessive or insufficient chemicals on the performance of the plating solution.

[0025] In this embodiment, the filtration mechanism 2 includes a filter barrel 201, which is fixedly installed on the top of the frame 1. A top cover 202 is provided on the top of the filter barrel 201. A filtrate outlet 203 is fixedly connected to the outer wall of the filter barrel 201, and an inlet pipe 204 is also fixedly connected to the upper part of the outer wall of the filter barrel 201. A pressure gauge 205 is installed on the top of the top cover 202. By setting the filter barrel 201 as the core filtration chamber and using the top cover 202 to achieve sealing protection, the pressure gauge 205 monitors the internal pressure in real time, thereby ensuring the stability of the filtration process, facilitating the observation of the equipment's operating status, and timely troubleshooting of abnormalities. The top cover 202 and the filter barrel 201 are connected by a quick-opening structure, which facilitates quick opening for filter media replacement or internal cleaning. The pressure gauge 205 has a range adapted to the working pressure range of the filter barrel 201, and the reading is clear and accurate.

[0026] It is worth noting that the end of the elbow joint 4 is connected to the end of the inlet pipe 204 via the quick-connect clamp 7. By setting the quick-connect clamp 7 to connect the elbow joint 4 and the inlet pipe 204, the assembly process is simplified, the connection efficiency is improved, the sealing reliability of the pipeline connection is ensured, and the disassembly and maintenance are facilitated. The quick-connect clamp 7 is made of stainless steel, and its clamping force can be adjusted by bolts to adapt to pipeline connections of different diameters. At the same time, the inner wall of the clamp is provided with anti-slip texture to prevent the pipeline from shifting during operation.

[0027] Working Principle: The electroless nickel plating solution first enters the longitudinally arranged stainless steel elbow 601 through the inlet flange 603 of the pipeline changing mechanism 6. During this process, if the composition of the plating solution needs to be adjusted, the required reagent can be precisely added to the pipeline through the flow control valve at the bottom of the chemical addition tank 8. After the reagent and plating solution are initially mixed in the stainless steel elbow 601, they are transported to the pump inlet 503 through the interface flange 602. The operator starts the motor 501, which drives the pump 502 to run at high speed through the power transmission structure, providing stable power for the plating solution transportation. The pump waterproof cover 506 effectively protects the core components of the motor 501 and the pump 502, preventing chemical corrosion. Under the action of the pump 502, the plating solution passes sequentially through the lower elbow joint 4, the connecting pipe 3, and the upper elbow joint 4, and enters the filter tank 201 through the inlet pipe 204 connected by the quick-connect clamp 7. The plating solution entering the filter tank 201 flows through the filter media under the internal pressure. The filter media filters out the fine nickel particles in the plating solution. Solid impurities such as particles and phosphites are efficiently intercepted and filtered. The filtered clean plating solution is discharged through the filtrate outlet 203 on the outer wall of the filter tank 201 and directly transported to the electroless nickel plating process tank for subsequent processing. During the entire operation, the operator can observe the pressure changes inside the filter tank 201 in real time through the pressure gauge 205 on the top of the cover 202. When the pressure rises abnormally, it can be determined that the filter material may be blocked, and the quick-opening cover 202 can be opened in time for treatment. The plug on the outer wall of the pump 502 ensures a good sealing environment inside the pump and maintains the normal working pressure. The sealing structure at each pipeline connection effectively prevents plating solution leakage. The overall structure optimizes the traditional pipeline route through the pipeline modification mechanism 6, reducing the effective liquid suction height of the pump inlet 503, so that the equipment can still operate normally under lower liquid level conditions. This not only ensures the filtration and impurity removal effect, but also meets the special needs of users for low liquid level installation and use, achieving a dual improvement in equipment applicability and process stability.
