Description

Technical Field

[0001] The utility model relates to a fluorination treatment device, in particular to a fluorination treatment device for improving the corrosion resistance of hydrogen storage alloys. Background Technique

[0002] Hydrogen storage alloy is an alloy material that can absorb and release hydrogen under certain conditions. Hydrogen storage alloy can reversibly absorb and release a large amount of hydrogen. Along with the hydrogen absorption (release) process, there is a heat release (absorption) effect. It selectively absorbs hydrogen energy, and the equilibrium pressure of hydrogen absorption and release changes sharply with temperature. After the hydrogen storage alloy undergoes corrosion resistance treatment, a protective film can be formed on the alloy surface to isolate the alloy from the contact with the corrosive medium, thereby significantly improving the service life of the alloy and being suitable for wide application in industry.

[0003] The common corrosion resistance treatment of hydrogen storage alloy is fluorination treatment. By placing the hydrogen storage alloy in a fluorination solution, chemical reaction occurs between fluorine element and the alloy surface to form a fluoride protective film, thereby improving the corrosion resistance of the alloy. However, this method requires strict control of the concentration of the fluorination solution and the treatment time to avoid over-corrosion of the alloy. In the prior art, a large number of hydrogen storage alloy workpieces are immersed in a fluorination pool by workers for fluorination treatment, and it is inevitable that the workpieces come into contact with each other, resulting in insufficient contact between the workpieces and the fluorination solution and affecting the uniformity and integrity of the fluorination treatment of the workpieces.

[0004] Based on this, it is necessary to design a high-efficiency fluorination treatment device for improving the corrosion resistance of hydrogen storage alloys. Content of the Utility Model

[0005] In order to overcome the shortcoming of low efficiency of fluorination treatment in the prior art, the technical problem of the utility model is: to provide a fluorination treatment device for improving the corrosion resistance of hydrogen storage alloys.

[0006] The technical solution is as follows: A fluorination treatment device for improving the corrosion resistance of hydrogen storage alloys includes a cylinder body, a first frame, a wire mesh, a second frame, a plugging component, a motor, and a gear component. A first frame with an arc-shaped opening is rotatably arranged in the cylinder body. A second frame for blocking the arc-shaped opening is connected to the first frame through a rotating shaft. A wire mesh is arranged on the first frame and the second frame. A plugging component is arranged between the first frame and the second frame, and the plugging component is used to fix the second frame on the first frame. A motor is arranged outside the cylinder body, and a gear component is arranged between the output shaft of the motor extending into the cylinder body and the end of the first frame. The output shaft of the motor drives the cylinder body to rotate through the gear component.

[0010] Further explanation: A water tank is fixedly connected to the side of the cylinder body opposite to the motor. A spray head fixedly connected to the cylinder body is provided above the water tank, and the water tank is communicated with the spray head through a connecting pipe.

[0011] Further explanation: A door panel is rotatably connected to the top of the cylinder body. Under normal conditions, the door panel blocks the through hole opened at the top of the cylinder body.

[0013] Further explanation: The first frame and the second frame are arc-shaped structures, and the first frame and the second frame are connected to form a cylinder with an internal space.

[0023] Embodiment: A fluorination treatment device for improving the corrosion resistance of hydrogen storage alloys, as Figures 2 - 4 shown, comprising a cylinder body 1, a first frame 6, a wire mesh 601, a second frame 602, a plugging assembly, a motor 7 and a gear assembly 8. A first frame 6 with an arc-shaped opening is rotatably arranged in the cylinder body 1. A second frame 602 for blocking the arc-shaped opening is connected to the first frame 6 through a rotating shaft. A wire mesh 601 is arranged on the first frame 6 and the second frame 602. A plugging assembly is arranged between the first frame 6 and the second frame 602, and the plugging assembly is used to fix the second frame 602 on the first frame 6. A motor 7 is arranged outside the cylinder body 1. A gear assembly 8 is arranged between the output shaft of the motor 7 extending into the cylinder body 1 and the end of the first frame 6. The output shaft of the motor 7 drives the cylinder body 1 to rotate through the gear assembly 8. Here, the output shaft of the motor 7 drives the gear assembly 8 to rotate, and the gear assembly 8 drives the first frame 6 to rotate, so that the workpiece in the first frame 6 rotates and rolls with the first frame 6, promoting the full contact between the workpiece and the fluorination liquid.

[0024] As Figure 5As shown, the plug-in component includes a fixing block 603, a bolt 604, and a guide rod 605. A fixing block 603 is fixedly connected to one side of the first frame 6. A guide rod 605 is fixedly connected to one side of the second frame 602. A bolt 604 is slidably connected to the guide rod 605. The bolt 604 is in plug-in fit with the fixing block 603. Here, a spring 606 is wound around the guide rod 605. Two ends of the spring 606 are respectively connected to the end of the guide rod 605 and the bolt 604. When the bolt 604 is slid upward, the spring 606 is compressed, and the bolt 604 disengages from the fixing block 603. At this time, the second frame 602 can be rotated. When the bolt 604 is slid downward and the bolt 604 is inserted into the fixing block 603, the second frame 602 is fixed and closes the first frame 6, and the spring 606 returns to its initial state. The spring 606 positions the bolt 604.

[0025] As Figure 1 shown, support feet 2 are fixedly connected to the length direction of the cylinder body 1. Here, the design of the support feet 2 can fix the device when the motor 7 is working, preventing the risk of component detachment when the device shakes.

[0026] As Figure 1 shown, a heating device 3 is arranged at the bottom of the cylinder body 1. The heating device 3 is used to increase the temperature inside the cylinder body 1. Here, to improve work efficiency, the heating device 3 can be used to raise the temperature inside the cylinder body 1 through the heating device 3, thereby increasing the activity of the fluorination liquid and the reaction rate between the fluorination liquid and the workpiece, achieving an improvement in work efficiency.

[0027] As Figure 1 shown, a water tank 4 is fixedly connected to the side of the cylinder body 1 opposite to the motor 7. A spray head 401 fixedly connected to the cylinder body 1 is arranged above the water tank 4. The water tank 4 is communicated with the spray head 401 through a connecting pipe 402. The cleaning liquid in the water tank 4 is conveyed to the spray head 401 by a water pump arranged in the water tank 4. The cleaning liquid is sprayed out from the spray head 401 and can clean the workpiece.

[0028] As Figure 1 shown, a door plate 5 is rotatably connected to the top of the cylinder body 1. Under normal conditions, the door plate 5 blocks the through hole opened at the top of the cylinder body 1. Here, the design of the door plate can prevent the fluorination liquid inside the device from splashing out during the fluorination treatment work, avoiding polluting the working environment.

[0029] As Figures 2 - 4 shown, the first frame 6 and the second frame 602 are arc-shaped structures, and the first frame 6 and the second frame 602 are connected to form a cylinder with an internal space. The arc-shaped structural characteristics of the first frame 6 and the second frame 602 can ensure the smooth rolling of the workpiece inside.

[0030] To improve the corrosion resistance of the hydrogen storage alloy, the hydrogen storage alloy needs to be fluorinated, and this device is used at this time. First, rotate the door panel 5 to open the device. Then, rotate the second frame 602, place the workpiece to be fluorinated on the first frame 6. Rotate the second frame 602 again to make it close to the first frame 6. Finally, pour a sufficient amount of fluorination liquid into the device and rotate the door panel 5 to close the device, thus completing the preparation work. Subsequently, start the motor 7. The output shaft of the motor 7 drives the gear assembly 8 to rotate. The gear assembly 8 drives the first frame 6 to rotate, so that the workpiece in the first frame 6 rotates and rolls with the rotation of the first frame 6, promoting the full contact between the workpiece and the fluorination liquid. After the fluorination treatment is completed, turn off the motor 7, rotate the door panel 5 to open the device, then use the robotic arm to pull up the first frame 6. After that, adjust the angle of the nozzle 401, and then use the water pump installed in the water tank 4 to convey the cleaning liquid in the water tank 4 to the nozzle 401. The cleaning liquid is sprayed out from the nozzle 401 to perform a preliminary cleaning on the fluorinated workpiece. After the cleaning work is completed, the workpiece can be taken out.

[0031] The above are only examples of the implementation of the present utility model and are not used to limit the present utility model. All equivalent replacements made within the principle of the present utility model shall be included within the protection scope of the present utility model. The content not elaborated in detail in the present utility model belongs to the well-known prior art in the technical field of this specialty.
