[0003] Existing purification devices often suffer from low maintenance efficiency when treating water-based passivation solutions due to the inconvenience of disassembling and assembling the filter mechanism, which affects continuous purification operations. At the same time, single filtration is difficult to effectively remove impurities and pollutants of different particle sizes, resulting in low purification accuracy and efficiency. Furthermore, the lack of intuitive monitoring methods for the purification process makes it difficult to detect abnormalities in a timely manner, which can easily lead to unstable purification effects and make it difficult to meet the high-standard purification requirements of environmentally friendly water-based passivation solutions.

[0004] Therefore, an environmentally friendly water-based passivation liquid purification device with multi-stage filtration is proposed. Utility Model Content

Furthermore, the lack of intuitive monitoring methods for the purification process makes it difficult to detect abnormalities in a timely manner, which can easily lead to unstable purification effects and make it difficult to meet the high-standard purification requirements of environmentally friendly water-based passivation liquids.

[0024] 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.

[0025] Please see Figure 1-6 The present invention provides the following technical solution:

[0026] An environmentally friendly water-based passivation liquid purification device with multi-stage filtration includes a purification box 1. The top of the purification box 1 is fixedly connected to an inlet pipe 3, and the surface of the inlet pipe 3 is provided with a first observation component 4. The inner wall of the purification box 1 is provided with a first filter frame 5, and the inner wall of the first filter frame 5 is movably connected to a coarse filter mechanism 2. The inner wall of the purification box 1 is provided with activated carbon felt sheets 6 and a fine filter mechanism 7. The bottom of the purification box 1 is fixedly connected to an outlet pipe 8, and the surface of the outlet pipe 8 is provided with a second observation component 9. The coarse filter mechanism 2 includes a mounting frame 201, the top of the mounting frame 201 is fixedly connected to a pull rod 202, the inner wall of the mounting frame 201 is fixedly connected to a coarse filter screen 203, and the surface of the mounting frame 201 is movably connected to the inner wall of the first filter frame 5.

[0027] In this embodiment: By setting up a coarse filtration mechanism 2, which combines a mounting frame 201, a pull rod 202, and a coarse filter screen 203, the coarse filtration mechanism 2 can efficiently intercept large particulate impurities in the aqueous passivation solution, preventing them from entering subsequent filtration stages and causing blockage or wear. Simultaneously, the movable connection between the mounting frame 201 and the first filter frame 5 facilitates the subsequent use of the pull rod 202 to pull out the mounting frame 201, allowing for quick disassembly, cleaning, or replacement of the coarse filtration mechanism 2. This significantly reduces maintenance difficulty and time costs, ensuring the continuous and stable operation of the coarse filtration stage and providing a pretreatment solution with higher cleanliness for subsequent purification processes, thus improving overall purification efficiency. By setting up a first observation group... The system consists of component 4 and purification box 1. Purification box 1 serves as the main frame, providing stable installation space for each purification component. Inlet pipe 3 ensures stable input of passivation liquid. First observation component 4 and second observation component 9 can monitor the inlet and outlet liquid status in real time, facilitating timely understanding of the purification situation. Activated carbon felt sheet 6 can adsorb organic pollutants, odors, and some small molecule impurities in the passivation liquid. Fine filtration mechanism 7 further removes fine particles and colloidal substances, improving the purification accuracy of the passivation liquid. Outlet pipe 8 efficiently outputs the purified passivation liquid. All structures work together to form a complete purification process from input, multi-stage filtration to output, improving the purification quality and treatment efficiency of environmentally friendly water-based passivation liquid.

[0028] Specifically, such as Figure 2 , Figure 3 As shown, a second filter frame 10 is movably connected to the inner wall of the purification box 1, and activated carbon felt 6 is placed on the inner wall of the second filter frame 10.

[0029] Specifically, such as Figure 2 , Figure 3 As shown, a third filter frame 11 is movably connected to the inner wall of the purification box 1, and the surface of the fine filtration mechanism 7 is movably connected to the inner wall of the third filter frame 11.

[0030] Specifically, such as Figure 2 , Figure 4 As shown, a baffle 12 is fixedly connected to the front side of the first filter frame 5, and the surface of the baffle 12 is bolted to the inner wall of the purification box 1.

[0031] In this embodiment: by setting a second filter frame 10 and a third filter frame 11, the second filter frame 10 provides stable installation and support for the activated carbon felt 6, ensuring that it maintains structural stability when the passivation liquid flows through, and fully exerts its adsorption efficiency. At the same time, the movable connection design facilitates the quick replacement or maintenance of the activated carbon felt 6, avoiding the impact of felt displacement on the adsorption effect. The third filter frame 11 effectively fixes the fine filtration mechanism 7, ensuring the stability of the mechanism position during the fine filtration process, improving the filtration accuracy of fine particles and colloidal substances. The movable connection method facilitates the disassembly, cleaning or replacement of the fine filtration mechanism 7, maintaining the continuous high efficiency of the fine filtration process. The bolted cooperation between the baffle 12 and the purification box 1 not only limits and fixes the first filter frame 5 to prevent it from shifting under the impact of the passivation liquid, but also allows the first filter frame 5 and the internal coarse filtration mechanism 2 to be quickly removed by disassembling the baffle 12, providing convenient operating space for the maintenance of the coarse filtration mechanism 2, and improving the installation stability and maintenance convenience of each filter component.

[0032] Specifically, such as Figure 4 As shown, a metal block 13 is fixedly connected to the inner wall of the mounting bracket 201, and a magnetic block 14 is fixedly connected to the inner wall of the first filter bracket 5. The bottom of the metal block 13 is magnetically connected to the top of the magnetic block 14.

[0033] Specifically, such as Figure 3 As shown, a sealing ring 15 is bonded to the rear side of the baffle 12, and the surface of the sealing ring 15 is engaged with the inner wall of the purification box 1.

[0034] In this embodiment: by setting metal block 13 and magnetic block 14, the magnetic connection between metal block 13 and magnetic block 14 can achieve quick positioning and stable fit during the installation of coarse filtration mechanism 2, avoiding the impact force generated by the flow of passivation liquid causing the mounting bracket 201 to loosen or shift, ensuring the stable operation of the coarse filtration process. At the same time, the magnetic connection method simplifies the installation and disassembly steps, further improving the maintenance efficiency of coarse filtration mechanism 2. The snap-fit ​​between sealing ring 15 and inner wall of purification box 1 can enhance the sealing between baffle 12 and purification box 1, effectively preventing passivation liquid from leaking from the gap between baffle 12 and the wall of purification box 1, avoiding resource waste and pollution to the external environment of the device, and ensuring the sealing and environmental protection of the purification process.

[0035] Specifically, such as Figure 6 As shown, a support assembly 16 is fixedly connected to the top of the purification box 1, and the inner wall of the support assembly 16 is snapped into the surface of the liquid inlet pipe 3.

[0036] Specifically, such as Figure 6 As shown, a connecting block 17 is fixedly connected to the left side of the first observation component 4, and a supplementary lighting component 18 is fixedly connected to the front side of the connecting block 17.

[0037] In this embodiment: By setting up a support component 16, the support component 16 provides a firm support for the liquid inlet pipe 3, preventing the liquid inlet pipe 3 from bending or shifting due to its own weight or external forces, ensuring that the passivation liquid can flow into the purification tank 1 stably and smoothly, and avoiding poor liquid supply caused by pipe deformation. By setting up a connecting block 17 and a supplementary lighting component 18, sufficient illumination can be provided for the first observation component 4 in low-light environments, enhancing the clarity of observation of the liquid inlet status, facilitating timely detection of abnormalities in the liquid inlet process, and ensuring the stable start-up of the purification process.

[0038] Working Principle: During the use of the purification chamber 1, the coarse filtration mechanism 2, through its combination design of mounting bracket 201, pull rod 202, and coarse filter screen 203, can efficiently intercept large particulate impurities in the aqueous passivation solution, preventing them from entering subsequent filtration stages and causing blockage or wear. Simultaneously, the movable connection between mounting bracket 201 and the first filter frame 5 allows for easy removal of mounting bracket 201 using pull rod 202, enabling quick disassembly, cleaning, or replacement of the coarse filtration mechanism 2. This significantly reduces maintenance difficulty and time costs, ensuring the continuous and stable operation of the coarse filtration stage and providing a pre-treatment solution with higher cleanliness for subsequent purification processes, thus improving overall purification efficiency. The first observation component 4 and the purification box 1 serve as the main frame, providing a stable installation space for each purification component. The inlet pipe 3 ensures a stable input of the passivation liquid. The first observation component 4 and the second observation component 9 can monitor the inlet and outlet liquid status in real time, facilitating timely understanding of the purification situation. The activated carbon felt sheet 6 can adsorb organic pollutants, odors, and some small molecule impurities in the passivation liquid. The fine filtration mechanism 7 further removes fine particles and colloidal substances, improving the purification accuracy of the passivation liquid. The outlet pipe 8 efficiently outputs the purified passivation liquid. All structures work together to form a complete purification process from input, multi-stage filtration to output, improving the purification quality and treatment efficiency of the environmentally friendly water-based passivation liquid.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
