Description

Technical Field

[0001] This utility model belongs to the field of nickel plating solution production technology, and particularly relates to a circulating filtration device for electroplating nickel plating solution. Background Technology

[0002] Nickel plating solution mainly consists of nickel sulfate, nickel chloride (or sodium chloride), and boric acid as its base components, with the addition of brighteners, wetting agents, etc., forming a chemical solution. Through electrochemical action, it can deposit a nickel layer on the metal surface, providing protection, decoration, and functionality.

[0003] Currently, filtration devices are typically used in the electroplating of nickel plating solutions to enable their circulation, filtration, and reuse. The function of this device is to remove impurities from the plating solution, prevent plating defects, ensure stable plating solution performance, and thus extend the service life of the plating solution and reduce production costs. However, existing filtration devices have some significant shortcomings: For example, poor filter element sealing performance. Poor filter element sealing is a common problem in nickel plating solution circulating filtration devices. This may be caused by loose screws on the top cover and pressure plate, or improper installation of the filter bag. Poor filter element sealing can lead to plating solution leakage, affecting not only the filtration effect but also potentially damaging the equipment. Furthermore, filter elements are inconvenient to install and remove.

[0004] In summary, existing electroplating nickel plating solution filtration devices suffer from problems such as poor filter element sealing and difficulty in disassembly and assembly. Utility Model Content

[0005] This utility model provides a circulating filtration device for electroplating nickel plating solution, which can solve the problems of poor filter element sealing and difficulty in disassembly and assembly in existing electroplating nickel plating solution filtration devices.

[0006] To achieve the above objectives, an electroplating nickel plating solution circulation filtration device is provided according to an embodiment of the first aspect of the present invention, comprising a filter tank and a tank cover disposed in the port on the top surface of the filter tank; The filter assembly includes a frame fixedly installed inside a filter canister, a filter shell disposed inside the frame, a filter element structure disposed inside the filter shell, and a corrugated pipe disposed inside the filter canister and connected at one end to the filter shell interface. Also includes: The pressing and fixing assembly includes a pair of electric cylinders symmetrically fixedly installed inside the filter tank and located on the side of the frame, a pressure ring fixedly sleeved on the bellows and connected to the rod of the electric cylinder, a sealing convex ring provided on the bottom surface of the pressure ring, and a ring of magnetic plates fixedly installed at the edge of the bottom surface of the pressure ring. The top surface of the frame is provided with a trapezoidal pressing notch, and a main magnet is provided inside the trapezoidal pressing notch to connect with the magnetic plate. A rubber ring is fixedly installed inside the filter shell interface.

[0007] A further improvement is that a connecting block is fixedly installed at the top of the rod of each electric cylinder, and the connecting block is fixedly connected to the side of the pressure ring by fixing bolts.

[0008] A further improvement is that several compression springs are fixedly installed on the inner wall array of the trapezoidal compression notch, and the main magnet is fixedly installed on the compression springs.

[0009] A further improvement is that the sealing ring is divided into a pressure ring section and a compression ring section; when the pressure ring is inside the filter housing interface, the outer wall of the compression ring section of the sealing ring contacts the inner wall of the rubber ring, and the bottom surface of the pressure ring section contacts the top surface of the rubber ring.

[0010] A further improvement is that the filter canister has an inlet at the upper side and an outlet at the lower side.

[0011] A further improvement is that the other end of the bellows is connected to the liquid inlet.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a pair of electric cylinders to retract their rods. As the rods retract, the sealing ring on the bottom surface of the pressure ring engages with the interface on the top surface of the filter housing, while simultaneously, the magnetic plate on the bottom surface of the pressure ring engages with the trapezoidal compression notch. When power is applied to the main magnet, it generates a magnetic field, attracting and adhering to the magnetic plate. During the continuous retraction of the electric cylinder rods, the main magnet compresses the spring within the trapezoidal compression notch. This structural design ensures a tight fit between the outer wall of the sealing ring's compression section and the inner wall of the rubber ring, while the bottom surface of the compression section is in close contact with the top surface of the rubber ring. This design significantly improves the sealing effect and effectively prevents leakage. Furthermore, this design facilitates quick assembly and disassembly of the filter element structure within the filter housing, greatly improving the overall filtration efficiency.

[0015] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] like Figure 1 As shown, the nickel plating solution circulation filtration device includes: The filter canister 1 and the canister cover 12 are provided in the port on the top surface of the filter canister 1. The upper side of the filter canister 1 is provided with a liquid inlet 13 and the lower side is provided with a liquid outlet 11. Filter assembly 2 includes a frame 21 fixedly installed in the filter tank 1, a filter shell 22 set in the frame 21, a filter element structure set in the filter shell 22 and a corrugated pipe 23 set in the filter tank 1 with one end connected to the interface of the filter shell 22, and the other end of the corrugated pipe 23 connected to the liquid inlet 13. It should be noted that the filter element structure can be one of the following: activated carbon filter element, ion exchange filter element, and membrane filter, or a combination of two of them, which are installed during filtration. The pressing and fixing assembly 3 includes a pair of electric cylinders 31 symmetrically fixedly installed inside the filter tank 1 and located on the side of the frame 21, a pressure ring 32 fixedly sleeved on the bellows 23 and connected to the rod of the electric cylinder 31, a sealing ring 33 provided on the bottom surface of the pressure ring 32 and a ring of magnetic plates 34 fixedly installed at the edge of the bottom surface of the pressure ring 32. A connecting block 311 is fixedly installed at the top of the rod of each electric cylinder 31. The connecting block 311 is fixedly connected to the side of the pressure ring 32 by fixing bolts. The top port of the frame 21 has a trapezoidal compression notch 201. A main magnet 35 is installed in the upper half of the trapezoidal compression notch 201, which, in conjunction with the magnetic plate 34, connects to the filter housing 22. A rubber ring 36 is fixedly installed inside the filter housing 22 interface. As the rod contracts, the sealing protrusion 33 on the bottom surface of the pressure ring 32 embeds into the interface on the top surface of the filter housing 22. Simultaneously, the magnetic plate 34 on the bottom surface of the pressure ring 32 also engages with the trapezoidal compression notch 201. When power is applied to the main magnet 35, it generates a magnetic field, which attracts and adheres to the magnetic plate 34. This structural design ensures that the outer wall of the compression ring section 302 of the sealing protrusion 33 is tightly fitted to the inner wall of the rubber ring 36, while the bottom surface of the compression ring section 301 is in close contact with the top surface of the rubber ring 36. This design significantly improves the sealing effect and effectively prevents leakage. In addition, this design facilitates the quick disassembly and assembly of the filter element structure inside the filter housing 22, greatly improving the overall filtration efficiency. In this embodiment, there is also a preferred implementation: several compression springs 37 are fixedly installed on the inner wall of the upper half of the trapezoidal pressing notch 201. The main magnet 35 is fixedly installed on the compression springs 37. The compression springs 37 are used for buffering to prevent the main magnet 35, magnetic plate 34 and sealing ring 33 from being damaged due to excessive pressure caused by the retraction of the rod of the electric cylinder 31. In this embodiment, there is also a preferred implementation scheme, wherein the sealing ring 33 is divided into a pressure ring section 301 and a compression ring section 302; when the pressure ring 32 is in the interface on the top surface of the filter shell 22, the outer wall of the compression ring section 302 of the sealing ring 33 contacts the inner wall of the rubber ring 36, and the bottom surface of the pressure ring section 301 contacts the top surface of the rubber ring 36, so as to improve the sealing performance.

[0017] In this embodiment, it should also be noted that the filtration device in the application document is actually a filter. The filter encloses a housing, and the housing contains the filtration structure, namely the filter housing 22 and the filter element structure. Furthermore, it should be noted that this application document only addresses the shortcomings of existing electroplating nickel plating solution filtration devices, such as poor filter element sealing and difficulty in disassembly and assembly, and does not involve other aspects. The improvement is achieved by using an electric pressing method to solve the problems in the background technology. The working principle of this electroplating nickel plating solution circulating filtration device is described below: In actual use, the on-site operator first installs the selected filter element structure into the filter housing 22, and then inserts the filter housing 22 with the filter element installed into the lower half of the trapezoidal pressing notch 201 on the top surface of the frame 21 and locks it in place.

[0018] Subsequently, a pair of electric cylinders 31 are activated, causing their rods to retract. As the rods retract, the sealing ring 33 on the bottom surface of the pressure ring 32 embeds into the interface on the top surface of the filter housing 22. Simultaneously, the magnetic plate 34 on the bottom surface of the pressure ring 32 also engages with the trapezoidal pressing notch 201. When the main magnet 35 is powered on, it generates a magnetic field, which attracts and adheres to the magnetic plate 34. During the continuous retraction of the electric cylinders 31, the main magnet 35 compresses the spring 37 in the trapezoidal pressing notch 201. This structural design ensures that the outer wall of the compression ring section 302 of the sealing ring 33 fits tightly against the inner wall of the rubber ring 36, while the bottom surface of the compression ring section 301 is in close contact with the top surface of the rubber ring 36. This design significantly improves the sealing effect and effectively prevents leakage. Furthermore, this design facilitates quick assembly and disassembly of the filter element structure within the filter housing 22, greatly improving the overall filtration efficiency.

[0019] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
