[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-5 As shown, the portable pipeline pickling and passivation tool includes a supporting outer box 1 and a liquid storage inner box 3. The supporting outer box 1 is provided with a round hole 2. A drain pipe 4 is fixed on the liquid storage inner box 3, and a valve 5 is provided on the drain pipe 4. A vibrator 6 is provided on the outer wall of the end of the liquid storage inner box 3, and a support frame 7 is provided inside the liquid storage inner box 3. A placement structure 9 is installed inside the liquid storage inner box 3.

[0022] A heating tube 8 is installed at the bottom of the inner storage tank 3. The end of the placement structure 9 is mounted on the support frame 7, and a handle 12 is provided at the end of the outer support tank 1. A support spring 10 is provided at the bottom of the inner support tank 1, and the inner storage tank 3 is mounted on the support spring 10. A vibration spring 11 is provided on the inner wall of the outer support tank 1, and the end of the vibration spring 11 is connected to the outer wall of the inner storage tank 3. The drain pipe 4 is connected to the inner storage tank 3 and passes through the circular hole 2 on the outer support tank 1. The drain pipe 4 is located in the circular hole 2. When the inner storage tank 3 moves, the circular hole 2 does not affect the movement of the drain pipe 4, and the valve 5 facilitates the opening of the drain pipe 4 for draining. Through the outer support tank 1 and the inner storage tank 3, the inner storage tank 3 is installed inside the outer support tank 1 via the support spring 10 and the vibration spring 11. When used with the vibrator 6, the vibration of the inner storage tank 3 carries the pickling solution during pickling and passivation, which can improve the pickling and passivation effect and shorten the pickling and passivation cycle.

[0023] When using a portable pickling and passivation box for pipe pickling and passivation, the tool is carried to a suitable location via handle 12 and placed accordingly. The placement structure 9 is then installed as needed. When the placement structure 9 has multiple layers, the pipe is placed after each layer of placement structure 9 is installed, followed by the installation of subsequent placement structures 9. After the pipe is placed, pickling solution is added to the inner storage tank 3. After connecting the power supply, the heating tube 8 is energized to heat the pickling solution, while the vibrator 6 operates to generate vibration. Under the combined action of the support spring 10 and the vibration spring 11, the inner storage tank 3 moves inside the outer support tank 1, thus carrying the pickling solution and increasing the pickling and passivation effect.

[0024] After pickling and passivation are completed, open valve 5 and drain the liquid using drain pipe 4. Then, remove the pipes from the top layer placement structure 9 and disassemble the top layer placement structure 9. Continue disassembling the pipes and placement structure 9 in sequence until all pipes have been removed.

[0025] According to the above implementation scheme, the placement structure 9 includes a first placement frame 901, a second placement frame 902, a placement rod 903, a filling short rod 904, and a connecting rod 909. Multiple placement rods 903 are evenly arranged on the first placement frame 901 and the second placement frame 902. The filling short rods 904 are installed on two placement rods 903 that are close to each other on the first placement frame 901 and the second placement frame 902. The filling short rods 904 arranged on the two placement rods 903 are staggered. The connecting rod 909 is fixed on the first placement frame 901, and the end of the connecting rod 909 is movably connected to the second placement frame 902.

[0026] Preferably, the placement structure 9 further includes a first fixing block 905, a second fixing block 906, a movable rod 907, and a return spring 908. The first fixing block 905 and the second fixing block 906 are respectively fixed on the first placement frame 901 and the second placement frame 902. The movable rod 907 is fixed on the first fixing block 905 and passes through the second fixing block 906. A stop is provided at the end of the movable rod 907. The return spring 908 is sleeved on the movable rod 907.

[0027] A support frame 7 is installed on the inner wall of the liquid storage tank 3. The support frame 7 is used to install the placement structure 9. The first placement frame 901 and the second placement frame 902 can be moved and retracted to facilitate the installation of the placement structure 9. At the same time, the position and number of placement structures 9 can be adjusted, which is highly flexible and adaptable. A movable rod 907 is provided on the first fixing block 905 and passes through the second fixing block 906. A return spring 908 is sleeved on the movable rod 907. After the placement structure 9 is installed, the return spring 908 provides elastic force to ensure that the two placement frames have an outward expansion tendency, which ensures the stability of the placement structure 9 in use, and does not affect the retraction and disassembly.

[0028] During the installation of the placement structure 9, a force is applied to the first placement bracket 901 and the second placement bracket 902, causing the two placement brackets to move closer together. The distance between the second fixing block 906 and the first fixing block 905 decreases, compressing the return spring 908. The staggered filling short rods 904 do not affect the normal retraction process. Then, the placement structure 9 is positioned at the corresponding height in the liquid storage tank 3. After releasing the placement brackets, under the action of the return spring 908, the first fixing block 905 and the second fixing block 906 move away from each other. The movable rod 907 and the connecting rod 909 ensure that the two placement brackets are in a horizontal connection state until the ends of the two placement brackets are inserted into the support frame 7. After the placement structure 9 is installed, the pipeline is placed using the placement rod 903 and the filling short rod 904 for support. Then, the pickling and passivation work begins. During this process, due to the action of the return spring 908, the entire placement structure 9 has good stability and will not loosen or fall off.

[0029] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
