Abstract
Description
Technical Field
[0001] This utility model relates to the field of chromium-free passivating agent processing technology, and in particular to a chromium-free passivating agent impurity removal machine. Background Technology
[0002] Passivation refers to the process of oxidizing a metal with a strong oxidizing agent or using electrochemical methods to make the surface of the metal in an inactive state, thus slowing down the corrosion rate of the metal. In addition, the phenomenon that an active metal or alloy becomes a precious metal state with greatly reduced chemical activity is also called passivation. Chromium-free passivating agents are chromium-free passivating agents. In order to reduce the use and emissions of chromium-free passivating agents, they are usually collected, purified, and reused. Currently, oxidizing agents are usually reacted with chromium-free passivating agents to turn impurities into solids for filtration and purification.
[0003] Chinese patent document CN219702586U discloses a chromium-free passivating agent impurity removal machine, including a top shell, a diverter, a bottom shell, an impurity removal component, and a fixing component. The diverter is fitted onto the top shell, which is fixedly connected to the top of the bottom shell. The impurity removal component is slidably inserted into the bottom shell. This chromium-free passivating agent impurity removal machine has shortcomings. Although it achieves impurity removal from chromium-free passivating agents, it has limitations. This setup only performs a single impurity removal on the passivating agent, resulting in poor impurity removal efficiency. Furthermore, after a period of use, a large amount of impurities adhere to the surface of the filter screen, deteriorating the filtration effect. Failure to replace the filter plate in time can easily allow impurities to pass directly through the filter screen, leading to filtration failure. Replacing the filter plate too early can waste the filter screen. It also makes it difficult to accurately determine when to replace the filter screen, making its use cumbersome.
[0004] Therefore, in order to solve such problems, we propose a chromium-free passivating agent removal machine. Utility Model Content
[0005] The purpose of this utility model is to provide a chromium-free passivating agent impurity removal machine, which aims to solve the problems in the above-mentioned background technology, where the existing chromium-free passivating agent impurity removal machines only remove impurities from the passivating agent once, resulting in poor impurity removal effect and difficulty in accurately determining when to replace the filter screen, making them cumbersome to use.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a chromium-free passivating agent impurity removal machine, comprising a top shell, a diversion shell sealed and fixedly connected to the lower end of the top shell, two filter shells sealed and fixedly connected to the two output ends of the diversion shell, a bottom shell sealed and fixedly connected to the end of the filter shell away from the diversion shell, two sliding grooves opened on the side wall of the filter shell, a first mounting groove opened on the side wall of the filter shell, the first mounting groove being located between the two sliding grooves, a mounting frame movably connected to the side wall of the filter shell, two mounting plates fixedly connected to the side wall of the mounting frame near the filter shell, the mounting plates slidingly connected to the sliding grooves, a second mounting groove opened at the upper end of the mounting plate, a filter plate engagingly connected inside the mounting plate, the filter plate being located in the second mounting groove, a limiting component provided on the side wall of the filter shell, the limiting component including a limiting plate, the limiting plate slidingly connected to the first mounting groove, a locking block fixedly connected to the lower end of the limiting plate, a spring fixedly connected to the lower end of the limiting plate, the end of the spring away from the limiting plate being fixedly connected to the bottom wall inside the first mounting groove, and a pulling block fixedly connected to the side wall of the limiting plate away from the filter shell.

The rotating shaft passes through the flow divider housing, and a baffle plate is fixedly connected to the side wall inside the flow divider housing. A first rubber plate is fixedly connected to both ends of the baffle plate, and the distance between the two first rubber plates and the rotating shaft is equal.
[0008] Preferably, a limiting post is fixedly connected to the inner sidewall of the filter shell, the upper surface of the limiting post is slidably connected to the lower end of the mounting plate, the limiting post is L-shaped, and a stop block is fixedly connected to the lower end of the mounting plate, the stop block is slidably connected to the sidewall of the limiting post.
[0009] Preferably, a second rubber plate is fixedly connected to the side wall of the mounting plate away from the mounting frame, and an inclined surface is provided at the end of the locking block away from the limiting plate.

[0012] This utility model has the following beneficial effects:
[0013] This invention features two sets of filter plates, enabling secondary filtration and impurity removal of the passivating agent. This results in more thorough filtration and improved filtration efficiency. Furthermore, it eliminates the need for precise timing of filter replacement, reducing the complexity of the process. Users can easily determine when to replace the upper filter plate by observing the adhesion of impurities on the lower plate, enhancing ease of use. The elasticity of the second rubber plate, combined with a locking block, secures the mounting plate, preventing wobbling and increasing the stability of the filter plate engagement. Finally, a single operation allows both filter plates to slide out of the groove simultaneously, reducing workload. Attached Figure Description

[0023] Reference Figure 1-5 This utility model provides an embodiment of a chromium-free passivating agent impurity removal machine, comprising a top shell 1, a diversion shell 11 sealed and fixedly connected to the lower end of the top shell 1, two filter shells 12 sealed and fixedly connected to the two output ends of the diversion shell 11, a bottom shell 13 sealed and fixedly connected to the end of the filter shell 12 away from the diversion shell 11, two sliding grooves 121 formed on the side wall of the filter shell 12, a first mounting groove 122 formed on the side wall of the filter shell 12, the first mounting groove 122 being located between the two sliding grooves 121, a mounting bracket 3 movably connected to the side wall of the filter shell 12, two mounting plates 31 fixedly connected to the side wall of the mounting bracket 3 near the filter shell 12, the mounting plates 31 and the... The slide groove 121 is slidably connected, and the upper end of the mounting plate 31 is provided with a second mounting groove 32. The mounting plate 31 is fitted with a filter plate 33, which is located in the second mounting groove 32. The side wall of the filter shell 12 is provided with a limiting component 14, which includes a limiting plate 141. The limiting plate 141 is slidably connected to the first mounting groove 122. The lower end of the limiting plate 141 is fixedly connected with a locking block 142 and a spring 143. The end of the spring 143 away from the limiting plate 141 is fixedly connected to the bottom wall of the first mounting groove 122. The side wall of the limiting plate 141 away from the filter shell 12 is fixedly connected with a pull block 144.
[0024] This setup involves pulling the pull block 144 vertically upwards, causing the pull block 144 to slide the limiting plate 141 vertically upwards within the first mounting groove 122. This causes the limiting plate 141 to pull the spring 143 and the locking block 142 vertically upwards, releasing the locking block 142 from its limiting position on the mounting frame 3. Then, the mounting frame 3 is pulled horizontally, moving it away from the side wall of the filter housing 12. Finally, the pull block 144 is released, allowing the mounting frame 3 to simultaneously pull the filter plates 33 from the two mounting plates 31 out of the filter housing 12. The two filter plates 33 can then be cleaned or replaced, achieving secondary filtration and increasing the impurity removal effect.
[0025] A stepper motor 2 is fixedly connected to the side wall of the flow divider shell 11. A rotating shaft 21 is fixedly connected to the output end of the stepper motor 2. The rotating shaft 21 passes through the flow divider shell 11. A flow baffle 22 is fixedly connected to the side wall of the rotating shaft 21 inside the flow divider shell 11. A first rubber plate 23 is fixedly connected to both ends of the flow baffle 22. The distance between the two first rubber plates 23 and the rotating shaft 21 is equal. The flow baffle 22 can block or guide the flow of the two filter shells 12 respectively by the forward and reverse rotation of the stepper motor 2. At the same time, the first rubber plates 23 are used to increase the flow blocking effect and prevent material leakage.
[0026] A limiting post 123 is fixedly connected to the inner wall of the filter housing 12. The upper surface of the limiting post 123 is slidably connected to the lower end of the mounting plate 31. The limiting post 123 is L-shaped. A stop block 35 is fixedly connected to the lower end of the mounting plate 31. The stop block 35 is slidably connected to the side wall of the limiting post 123. The limiting post 123 is used to increase the stability of the filter plate 33 in the filter housing 12. At the same time, the stop block 35 is used to limit the mounting plate 31 and prevent the mounting plate 31 from sliding directly out of the filter housing 12.
[0027] The mounting plate 31 is fixedly connected to the side wall away from the mounting frame 3 with a second rubber plate 34. The end of the locking block 142 away from the limiting plate 141 is provided with an inclined surface. By pressing the mounting frame 3 with the locking block 142, the mounting frame 3 presses the mounting plate 31 into the filter shell 12, which in turn causes the mounting plate 31 to press the second rubber plate 34. The elastic properties of the second rubber plate 34 make the locking block 142 more firmly fixed to the mounting frame 3, preventing the mounting frame 3 from shaking.
[0028] The first mounting groove 122 is T-shaped, and a limiting block 145 is fixedly connected to the side wall of the limiting plate 141 to limit the limiting plate 141 and increase the movement stability of the limiting plate 141.
[0029] A rubber scraper 124 is fixedly connected to the inner wall of the filter housing 12. The rubber scraper 124 is slidably connected to the lower surface of the filter plate 33 and is used to scrape off the passivating agent adhering to the lower surface of the filter plate 33 to prevent the passivating agent from dripping onto the outside of the filter housing 12.
[0030] Working principle: The passivating agent is filtered using two filter plates 33 to achieve secondary filtration. When it is necessary to replace the filter plate 33 in one of the filter shells 12, the stepper motor 2 is started first. The flow-blocking plate 22 obstructs and guides the flow in the two filter shells 12 respectively. At the same time, the first rubber plate 23 is used to increase the flow-blocking effect and prevent material leakage. Then, the pull block 144 on the side wall of the filter shell 12 after the flow is blocked is pulled vertically upward. The pull block 144 drives the limiting plate 141 to slide vertically upward in the first mounting groove 122. The limiting plate 141 pulls the spring 143 and the locking block 142 vertically upward. The locking block 142 releases the limiting of the mounting frame 3. Then, the mounting frame 3 is pulled horizontally away from the side wall of the filter shell 12. Then, the pull block 144 is released. The mounting frame 3 is used to pull the filter plates 33 in the two mounting plates 31 out of the filter shell 12 at the same time. Then, the two filter plates 33 are cleaned or replaced.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
