Abstract
Description
Technical Field
[0001] This utility model belongs to the field of passivation tank technology, specifically relating to a passivation tank device with bottom mud isolation function. Background Technology
[0002] A passivation tank is a device used for metal surface treatment, primarily to form a passivation film on the metal surface through a chemical reaction, thereby achieving rust prevention and metal protection. Passivation tanks typically use spraying or immersion methods to react the metal with a passivating agent, forming a protective film on the metal surface. Alternatively, the passivation tank may use strong oxidizing agents or electrochemical methods to oxidize the metal, making its surface inactive, i.e., passivated. This process transforms the metal surface into a state that is not easily oxidized, thus slowing down the corrosion rate of the metal.
[0003] When metal reacts with passivating agent, a certain amount of bottom mud is generated, and the bottom mud will settle at the bottom of the passivation tank. When there is too much bottom mud, it will affect the passivation efficiency of the metal, resulting in incomplete passivation of the metal surface. The problem that this device addresses is how to easily isolate the bottom mud and passivating agent. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides the following technical solution: a passivation tank device with bottom sediment isolation function, including a working box 1, a collection box 8 fixedly installed at the bottom of the working box 1, and mounting boxes 2 fixedly installed on both the left and right sides of the working box 1. A drive motor 12 is fixedly installed on the surface of the mounting box 2, and an eccentric vibrator 23 is fixedly installed on the drive motor 12 through the rotating shaft at the output end. A connecting plate 13 is fixedly installed at the bottom of the mounting box 2, and the connecting plate 13 is fixedly connected to the left and right sides of the collection box 8. An isolation plate is fixedly installed between the working box 1 and the collection box 8. The work box 1 has fixed plates 19 on both the left and right sides inside, and the fixed plates 19 are inclined. A movable knob 10 is movably installed in the middle of the back of the work box 1. A movable rod 20 is fixedly installed on one side of the movable knob 10. A movable plate 21 is fixedly installed on the surface of the movable rod 20, and the movable rod 20 is movably connected to the work box 1. A servo motor 11 is fixedly installed on both the left and right sides of the back of the work box 1. A stirring blade 22 is fixedly installed on the servo motor 11 through the rotating shaft of the output end, and the stirring blade 22 is located below the fixed plate 19.
[0022] When the device is in use, the fixed plate 19 and the movable plate 21 facilitate the isolation of the upper and lower passivating agents. The movable knob 10 allows the movable rod 20 and the movable plate 21 to rotate, facilitating the exchange and mixing of the upper and lower passivating agents. Then, the servo motor 11, through its output shaft, drives the stirring blades 22 to rotate, making the passivating agent inside the working chamber 1 more active and improving the passivation efficiency of the metal. After the passivation reaction is complete, the drive motor 12 is activated, through its output shaft... The rotating shaft can drive the eccentric oscillator 23 to rotate, which can cause the collection box 8 to vibrate slightly. This allows the bottom sludge produced by the passivation reaction to enter the interior of the collection box 8, completely isolating the bottom sludge and passivating agent, preventing the bottom sludge from settling inside the working box 1 and affecting the reaction rate of the metal inside the working box 1. The mounting plate 15 facilitates the installation of the switch button 16 and the adjustment knob 17. The motor controller 5 is electrically connected to the drive motor 12, and since the switch button and adjustment knob are also electrically connected to the motor controller 5, the... The switch button allows users to easily control the start and stop of the drive motor 12, and the adjustment knob allows users to easily adjust the rotation speed of the drive motor 12, increasing the versatility of the device. The hinge 3 facilitates the installation and fixation of the movable cover 4. During the passivation reaction, fastening the movable cover 14 prevents the passivating agent from spilling out of the working chamber 1. The observation window 6 and observation plate 7, being transparent, allow observation of the metal passivation status inside the working chamber 1. Observation helps improve the ease of use of the device. As for the setting of the support pad 14, since there are multiple support pads 14 and they are arranged linearly at the bottom of the collection box 8, the friction between the bottom of the collection box 8 and the ground can be increased, making the device less likely to slide on the ground. By unscrewing the movable cap 9, it is easy to clean the bottom mud inside the collection box 8. The anti-slip texture makes it easier to unscrew the movable cap 9. All electrical equipment in this device is powered by an external power source.
[0023] In one aspect of this embodiment, the hinge 3 facilitates the installation and fixation of the movable cover 4. During the passivation reaction, the passivating agent can be prevented from spilling out of the working chamber 1 by fastening the movable cover 14. As for the observation window 6 and the observation plate 7, since the observation plate 7 is transparent, the passivation of the metal inside the working chamber 1 can be observed through the observation plate 7, which helps to improve the ease of use of the device.
[0024] In one aspect of this embodiment, the mounting plate 15 facilitates the installation of the switch button 16 and the adjustment knob 17. The motor controller 5 is electrically connected to the drive motor 12, and since both the switch button and the adjustment knob are electrically connected to the motor controller 5, the user can easily control the start and stop of the drive motor 12 through the switch button, and can easily adjust the rotation speed of the drive motor 12 through the adjustment knob, thus increasing the versatility of the device.
[0025] In one aspect of this embodiment, the arrangement of the support pads 14, and the fact that there are multiple support pads 14 arranged linearly at the bottom of the collection box 8, increases the friction between the bottom of the collection box 8 and the ground, making the device less prone to sliding on the ground. By unscrewing the movable cap 9, it is easy to clean the bottom mud inside the collection box 8. The anti-slip texture makes it easier to unscrew the movable cap 9.
[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
