[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0029] Example 1, such as Figures 1-11 As shown, the specific structure of this embodiment is as follows: a linear cleaning system, which includes a lifting device for hoisting the pipe rack 1. The lifting device can be a crane or the like in the prior art, or a track can be set. A load-bearing vehicle driven by a traction rope or the like is set on the track. A vertical drive mechanism is set on the load-bearing vehicle. A hook is set on the piston rod of the vertical drive mechanism. The hook is used to hook the pipe rack 1. The pipe rack 1 moves laterally under the action of the lifting device, and the pipe rack can be lifted and lowered.

[0030] Below the lateral movement path of the pipe rack 1, a loading area 2, a pickling area, a cleaning area, a drying area, and a unloading area 6 are sequentially arranged. The pipe rack 1 includes a crossbeam 101. In this embodiment, the crossbeam 101 is arranged in the same direction as the pipe rack 1, and the length direction of the pipe rack 1 is the lateral movement direction of the pipe rack 1. Columns 102 are spaced apart along the length direction at the lower end of the crossbeam 101. Placement beams 103 are arranged on the side walls of the column 102. The placement beams 103 extend along the width direction of the crossbeam 101. To ensure balance, placement beams 103 are symmetrically arranged on both sides of the column. To increase the processing capacity of pipes 7, multiple placement beams 103 are spaced apart along the height of the column. Pipes 7 are placed on the upper end of placement beams 103. To ensure that pipes 7 do not fall during the movement of the pipe rack, a baffle 105 is provided at the end of placement beam 103. The baffle 105 is higher than the upper surface of placement beam 103. During the loading process, the pipe rack 1 is placed on the ground of loading area 2. For this purpose, a base 106 is provided at the lower end of column 102. The base 106 can be a planar frame structure welded from multiple pipes. The outer diameter of the base 106 is larger than that of column 102 to increase the grounding area. Support beams 104 are spaced apart along the length of the upper end of the crossbeam 101. Both ends of the support beams 104 extend along the width of the crossbeam 101. To improve balance, two support beams 104 are provided in this embodiment. Therefore, four hooks are also provided on the lifting equipment. The end face of the support beam 104 exceeds the end face of the placement beam 103, that is, the length of the support beam 104 exceeds the distance between the end faces of the placement beams 103 at the same height.

[0031] The pickling zone is equipped with an open-top pickling tank 3. The bottom of the pickling tank 3 has an acid outlet with a valve connected to an acid treatment mechanism. The top of the pickling tank 3 is connected to an acid storage area. The entire linear cleaning system can be used as follows: Figures 2-3 As shown, all components are uniformly installed in a sealed chamber. An observation window is installed on the side wall of the sealed chamber, and doors are located at both ends. An exhaust mechanism 12 is installed within the sealed chamber. The exhaust mechanism 12 includes a duct connected to an exhaust fan and an air inlet connected to the duct and facing the pickling tank 3 to remove acid mist generated during the pickling process. Alternatively, a hood 13 can be installed on one side of the pickling tank, connected to an exhaust fan, to remove acid mist. An ultrasonic generator or similar device can be installed on the side wall of the pickling tank 3 to agitate the liquid inside. A temperature control mechanism is installed inside the pickling tank 3, which can be a combination of an electric heating element and a cooler. In this embodiment, the temperature control mechanism includes a temperature regulating pipe 308, with its two ends serving as an inlet and outlet. The inlet and outlet extend from the pickling tank 3 and are connected to a temperature control device, which can be an oil temperature controller, a water temperature controller, or a water tank or pool for storing liquids such as water. The temperature control tube 308 is coiled on the inner wall of the pickling tank 3.

[0032] At least one cleaning tank 4 is provided in the cleaning area. The cleaning tank 4 is open at the top. A liquid inlet pipe 401 is provided at the top of the cleaning tank 4. A liquid outlet pipe 402 is provided at the bottom of the cleaning tank 4. An air pipe 403 is provided inside the cleaning tank 4. The air pipe 403 is arranged along the length of the cleaning tank 4. Nozzles 404 are arranged at intervals on the air pipe 403. One end of the air pipe 403 extends out of the cleaning tank 4 and is connected to a bubbling air source. The cleaning tank 4 contains water or other cleaning liquid.

[0033] A neutralization tank 8 with an open top is provided between the cleaning tank 4 and the pickling tank 3 in the cleaning area. The structure of the neutralization tank 8 can be the same as that of the cleaning tank 4 or the pickling tank 3, except that the neutralization tank 8 contains alkaline solution to neutralize the acid solution adhering to the pipe 7. The neutralization tank 8 is provided with a liquid vibration mechanism, which can be an ultrasonic vibration mechanism or a bubbling mechanism.

[0034] The drying zone is equipped with an open-top drying chamber 5, which contains a drying mechanism. The side walls of the pickling chamber 3 and the drying chamber 5 can be double-layered with hollow interiors to achieve heat insulation and other effects, further ensuring production safety.

[0035] The drying chamber 5 has a cover plate 501 at its upper open end, which can be opened or closed to allow the drying chamber 5 to be opened and closed. The drying mechanism includes a heating mechanism 502 and an air inlet 503 and an air outlet 504 spaced apart on the side wall of the drying chamber 5. The heating mechanism 502 can be an existing electric heating tube, infrared drying equipment, etc., and a protective net is provided on the outside of the heating mechanism 502. The air inlet 503 is connected to a hot air blower, a blower, or other air supply mechanism, and the air inlet 503 and the air outlet 504 allow the gas inside the drying chamber 5 to circulate, improving the drying efficiency. A drain outlet with a valve can also be provided at the bottom of the drying chamber 5.

[0036] Pickling tank 3, cleaning tank 4 and neutralizing tank 8 are provided with corresponding card seats 9 on the upper side wall and the inner side wall of drying tank 5. The upper end of the card seat 9 is provided with a card groove 10 that cooperates with the support beam 104.

[0037] The specific working process is as follows: Workers place multiple pipes 7 on different support beams 103 of the pipe rack 1 in the loading area. Then, using lifting equipment, the loaded pipe rack 1 is lifted and sequentially fed into the pickling tank 3, neutralization tank 8, cleaning tank 4, and drying tank 5, thus completing multiple cleaning processes including pickling, acid removal, and drying. During the cleaning process, the support beams 104 of the pipe rack 1 are engaged in the slots 10. During pickling in the pickling tank 3, the acid mist is extracted. When the drying tank 5 is in operation, the drying tank 5 is closed.

[0038] Example 2, as Figures 6-8As shown, the other structures and working processes of this embodiment are the same as those of Embodiment 1. However, in this embodiment, lifting parts 301 are symmetrically arranged inside the pickling tank 3. When the pipe rack 1 is immersed in the pickling tank 3, the lifting parts 301 are located at both ends of the length direction of the pipe 7. The lifting parts 301 move vertically under the action of linear drive mechanisms such as oil cylinders and linear modules. In this embodiment, a sliding groove is provided on the inner side wall of the pickling tank 3. The lifting parts 301 and the sliding groove are keyway-fitted. A lead screw and a guide post are provided in the sliding groove. The lead screw is threadedly connected to the lifting parts 301. The guide post is slidably fitted to the lifting parts 301. One end of the lead screw is drivenly connected to the lifting motor 11. The lifting motor 11 is installed on the outside of the pickling tank 3.

[0039] A support 302 is provided on the lifting part 301. The upper end of the lifting part 301 and the lower end of the support 302 are keyway-fitted. A pushing mechanism 309 is provided on the outer side of the side wall of the pickling tank 3. The pushing mechanism 309 can be a hydraulic cylinder, an electric push rod, etc. The piston rod of the pushing mechanism 309 passes through the shaft seal on the side wall of the pickling tank 3 and extends into the pickling tank 3 to connect with the pushing part 310. The position of the pushing part 310 is adapted to the support 302. Under the drive of the pushing part 310, the support 302 moves back and forth along the width direction of the crossbeam 101.

[0040] A sealing shell 303 is provided on the support 302. A transverse drive mechanism is provided inside the sealing shell 303. The transverse drive mechanism can be an electric push rod, a cylinder, etc. The piston rod of the transverse drive mechanism extends out of the sealing shell 303 through the shaft seal on the side wall of the sealing shell 303. The transverse drive mechanism pushes the mounting plate 304 to move along the length of the pipe 7. The mounting plate 304 and the side wall of the support 302 are keyway fitted. A connecting part 305 is provided on the mounting plate 304.

[0041] During and after pickling, the heights of the two lifting parts 301 are inconsistent. Therefore, the connecting part 305 is provided on the rotating part 306. The rotating part 306 is rotatably disposed in the mounting hole on the mounting plate 304. When the rotating part 306 is horizontal, its lower end face is in contact with the lower end face of the mounting hole. The height of the mounting hole is greater than the height of the rotating part 306 so that the rotating part 306 can swing in the mounting hole. One end of the rotating part 306 is set as an arc surface, wherein the arc surface of the higher side rotating part 306 faces the inside of the pickling tank 3, and the arc surface of the lower side rotating part faces the outside of the pickling tank 3. The center of the arc surface is collinear with the rotation axis of the rotating part 306. A limiting part 307 is provided on the outer side of the connecting part 305 on the lower side. An extension part extending into the pickling tank 3 is provided below the mounting plate 304 on the lower side and the bottom wall of the mounting hole. The extension part prevents the rotating part 306 on the lower side from swinging downward at one end inside the pickling tank 3. A counterweight is provided inside the rotating part 306 on the higher side.

[0042] Specific working process: Before the pipe 7 on the pipe rack 1 is immersed in the acid in the pickling tank 3, the height of the lifting parts 301 on both sides is kept uniform and raised synchronously until the lifting parts 301 are higher than the acid and the connecting parts 305 are aligned with the pipe 7. To ensure that the connecting parts 305 and the pipe 7 are aligned, a mark can be set on the upper end of the placement beam 103. When placing the pipe 7, the staff will align the pipe 7 with the mark.

[0043] Subsequently, the mounting plate 304 moves towards the pipe 7 under the push of the lateral drive mechanism until the connecting part 305 extends into the pipe 7. Then, the pipe 7, along with the lifting part 301, is immersed in the acid solution of the pickling tank 3 for pickling. During the pickling process, the pushing part 310 moves along the width of the pickling tank 3, i.e., the width of the crossbeam 101, under the action of the pushing mechanism 309, thereby pushing the support 302 to move along the width of the pickling tank 3. As the support 302 moves, the connecting part 305 causes the pipe 7 to move laterally, thereby improving the pickling efficiency.

[0044] During or after pickling, the lifting part 301 on one side rises to a certain height, thereby causing the pipe 7 to change from a horizontal state to an inclined state, and the limiting part 307 abuts against the lower end face of the pipe 7.

[0045] Under the influence of gravity, rust and other impurities in pipe 7 move towards the lower side of pipe 7 until they are discharged. After pickling, the lifting units 301 on both sides rise synchronously. Since pipe 7 is tilted at this time, when pipe 7 floats out of the acid solution, the acid solution inside pipe 7 will flow out from the lower side of pipe 7, reducing the amount of acid solution remaining in pipe 7. After pipe 7 and the material rack float out of the acid solution, the higher side lifting unit 301 stops moving, while the lower side lifting unit 301 continues to move upward until the lifting units 301 on both sides are level again, at which point pipe 7 returns to a horizontal state. After pipe 7 returns to a horizontal state, the lifting equipment lifts pipe rack 1 again and moves it to the next process, while the lifting unit 301 resets.
