[0001] The present application relates to the technical field of impurity removal of passivation solution, and more specifically, to an impurity removal device for zinc-plated trivalent chromium colored passivation solution. Background Art

[0002] Passivation refers to the process of metal being oxidized by strong oxidants or electrochemical methods to make the surface inactive, which is a method of transforming the metal surface into a state that is not easily oxidized and slowing down the corrosion rate of the metal. In addition, the phenomenon of an active metal or alloy, in which the chemical activity is greatly reduced and becomes a precious metal state, is also called passivation. Trivalent chromium color is a commonly used passivation solution for zinc plating.

[0003] The search publication number: CN219772258U discloses a device for removing impurities from galvanized trivalent chromium color passivation liquid, including a bottom plate, the upper end surface of the bottom plate is fixedly connected with a liquid storage cylinder, the upper end surface of the bottom plate is symmetrically fixedly connected with four fixed rods, and the upper ends of the plurality of fixed rods are commonly fixedly connected with a top plate. The utility model can drive the stirring rod to rotate through the reduction motor, the turntable and the vertical rod, and the stirring rod can stir the galvanized trivalent chromium color passivation liquid, so that the metal casting and the galvanized trivalent chromium color passivation liquid fully undergo a passivation reaction; the disk is driven to move upward by the hydraulic telescopic rod, the fixed block, the baffle and the push rod, so that the metal casting is conveniently taken out of the galvanized trivalent chromium color passivation liquid, and the impurities generated during the passivation process can be filtered and processed through the screen, and there is no need to discharge the passivation liquid for cleaning later, which saves time and effort, and thus facilitates the cleaning of impurities in the passivation liquid.

[0004] In the above patent, impurities in the passivation liquid are filtered by setting a screen. The screen holes may be clogged after long-term use. Since the screen is fixed on the disc by bolts, the staff cannot quickly install or disassemble the screen, which is not convenient for subsequent cleaning or replacement operations.

[0005] In order to solve the above problems, the present application provides a device for removing impurities from zinc-plated trivalent chromium colored passivation liquid. Utility Model Content

[0035] See also Figure 5 and Figure 6 The connecting assembly 8 includes a mounting plate 81 mounted on the top of the mounting frame 16, two symmetrical through slots 82 are provided inside the mounting plate 81, two symmetrical slide slots 83 are provided on the top of the mounting plate 81, a telescopic rod 84 and a first spring 85 are respectively provided on one side of the inner side of the through slot 82, the first spring 85 is located outside the telescopic rod 84, a card plate 86 is provided on one end of the telescopic rod 84 and the first spring 85, a push plate 87 is provided on one end of the top of the card plate 86, a connecting slot 88 is provided at the inner center of the mounting plate 81, a connecting plate 89 is connected to the inner side of the connecting slot 88, the connecting plate 89 is connected to the connecting rod 7, card slots 810 are provided on both sides of the outer side of the connecting plate 89, and the card slots 810 and the card plate 86 are in a card-fitting structure;

[0036] When the connecting plate 89 is separated from the connecting groove 88 provided in the mounting plate 81, the mounting frame 16 and the stirring device 9 installed at the bottom can be disassembled. The stirring device 9 can be quickly installed or disassembled through the setting of the connecting assembly 8, and different types of stirrers can be replaced and the subsequent maintenance work of the staff can be facilitated. The push plate 87 is located at the position of the slide groove 83 and slides. The push plate 87 can drive the card plate 86 to move, and the card plate 86 penetrates and extends to the position of the connecting groove 88;

[0037] See also Figure 7 The disassembly assembly 13 includes a fixing plate 131 arranged on the top of the screen 12, a second spring 137 and two symmetrical connecting frames 132 are respectively installed on the top of the fixing plate 131, a connecting shaft 133 is commonly connected to the inside of the two connecting frames 132, a connecting seat 134 is connected to the outside of the connecting shaft 133, a fixing frame 135 is installed on the top of the connecting seat 134, a pressing plate 136 is installed at one end of the fixing frame 135, and a limiting rod 138 is installed at one end of the bottom of the fixing frame 135;

[0038] The limiting rod 138 is located inside the sealing ring 15, which can increase the tightness of the connection between the screen 12 and the disc 11. The setting of the pressing plate 136 makes it convenient for the user to press down one end of the fixing frame 135.

[0039] The implementation principle of this embodiment is: when the screen 12 and the stirring device 9 need to be replaced or cleaned, the user only needs to start the hydraulic telescopic rod 2 to separate the stirring device 9 from the inside of the liquid storage cylinder 5 to carry out the disassembly and assembly work;

[0040] When the screen 12 needs to be disassembled and cleaned, the user only needs to hold the pressing plate 136 to press the fixing frame 135 downward, and one end of the bottom of the fixing frame 135 squeezes the second spring 137. The connecting seat 134 installed at the bottom of the fixing frame 135 is located inside the two connecting frames 132 through the connecting shaft 133 and rotates. When pressing the pressing plate 136, one end of the fixing frame 135 is lifted upward, so that the limiting rod 138 is separated from the inside of the sealing ring 15, and the screen 12 can be taken out from the inside of the disc 11. When installing the screen 12 later, it is only necessary to locate the limiting rod 138 inside the sealing ring 15.

[0041] When the stirring device 9 is disassembled, the user holds the two push plates 87 and moves them to both ends. The push plates 87 drive the card plate 86 to move into the through slot 82. At this time, the card plate 86 squeezes the telescopic rod 84 and the first spring 85 until the card plate 86 is completely located in the through slot 82, and the connecting plate 89 can be separated from the connecting slot 88 opened in the mounting plate 81. At this time, the stirring device 9 is disassembled; when the stirring device 9 is subsequently installed, the two push plates 87 are also held and moved to both ends until the card plate 86 is completely located in the through slot 82, and the connecting plate 89 is located in the connecting slot 88, and then the push plates 87 are released, and the connecting plate 89 is fixed to the mounting plate 81 by the setting of the telescopic rod 84 and the first spring 85. At this time, the stirring device 9 is successfully installed.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
