The outer frame plays a role in protection and facilitating transportation. In actual use, after the raw materials in the tank are used up, the tank needs to be cleaned to facilitate the subsequent cleaning of the container. For the cleaning of the inner wall of the tank, there are currently some automated devices. For example, the utility model patent with the authorization announcement number CN220697733U discloses a cleaning device for the inner wall of a ton barrel based on high-pressure water. It uses the method of inserting the cleaning head deep into the ton barrel to clean the inner wall of the ton barrel. However, in actual operation, since the cleaning head cannot rotate, it can only move up and down inside the tank. There are situations where the liquid or powder attached to the inner wall of the tank cannot be sprayed by the cleaning head, resulting in poor cleaning effect for the inner wall of the tank. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a cleaning device for the inner wall of a large tank to solve the above problems existing in the current cleaning of the inner wall of a large tank.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A cleaning device for the inner wall of a large tank includes a frame, a tank transportation mechanism, an inner wall cleaning mechanism of the tank, and a docking sewage discharge mechanism. The tank transportation mechanism is arranged at the bottom of the frame and is used for transporting the tank to be cleaned. The inner wall cleaning mechanism of the tank is arranged at the top of the frame. The docking sewage discharge mechanism is arranged on the side of the frame and is used for docking with the drain pipe at the bottom of the tank. The inner wall cleaning mechanism of the tank includes an up-and-down moving component, a cleaning pipe, and a cleaning pipe rotating component.

The inner wall cleaning mechanism of the tank body 30 is arranged at the top of the frame 10 and is responsible for efficiently cleaning the inner wall of the tank body. The docking sewage discharge mechanism 40 is arranged on the side of the frame 10 and is used to dock with the drain pipe at the bottom of the tank body to discharge the sewage after cleaning.

[0023] As Figure 3As shown, the tank transport mechanism 20 includes a first drive motor 21, a drive chain 22 and two support beams 23. The two support beams 23 are arranged in parallel and spaced apart at the bottom of the frame 10, and the drive chain 22 is wound around the two support beams 23 to form a closed loop. The first drive motor 21 is connected to one end of the drive chain 22 through a transmission device such as a gear or a sprocket, and the drive chain 22 moves cyclically along the support beams 23. The tank is placed on the drive chain 22 and is transported forward or backward as the chain moves.

[0024] In order to guide the tank body to move smoothly on the driving chain 22, a guide plate 24 is also provided on the support beam 23. The end of the guide plate 24 is tilted outward to form a certain angle, which helps the tank body to keep moving straight and avoid deviation during the movement.

[0025] like Figure 4 As shown, the tank inner wall cleaning mechanism 30 includes an up and down moving component 31, a cleaning pipe 32 and a cleaning pipe rotating component 33.

[0026] The up-and-down moving assembly 31 includes a vertical support plate 311, a slide rail 312, a second drive motor 313 and a slider 314. The vertical support plate 311 is fixed on the frame 10 in the up-and-down direction, and the slide rail 312 is arranged on both sides of the vertical support plate 311. A first synchronous pulley is respectively arranged on the top and bottom of the vertical support plate 311, and a first synchronous belt is wound between the two first synchronous pulleys. The second drive motor 313 is fixed on one side of the vertical support plate 311 and is connected to one of the first synchronous pulleys in a transmission manner. The slider 314 is slidably arranged on the slide rail 312 and is connected to the first synchronous belt through a connecting piece. When the second drive motor 313 is started, the slider 314 is driven to move up and down on the slide rail 312 through the first synchronous belt.

[0027] The cleaning pipe rotating assembly 33 is arranged on the slider 314, and includes a third driving motor 331, a second synchronous pulley, a second synchronous belt 332 and a bracket 333. The bracket 333 is fixedly connected to the slider 314, and the third driving motor 331 is arranged on the bracket 333. The cleaning pipe 32 is arranged in the up and down direction, and is rotatably arranged on the bracket 333 through bearings, one of which is transmission-connected to the third driving motor 331, and the other is sleeved on the cleaning pipe 32. When the third driving motor 331 is started, the cleaning pipe 32 is driven to rotate through the second synchronous belt 332.

[0028] The lower end of the cleaning pipe 32 is provided with a cleaning head 321 for spraying high-pressure water or other cleaning liquid to clean the inner wall of the tank body. In addition, the cleaning pipe 32 is also provided with a cover 322 for shielding the entrance of the tank body during the cleaning process to prevent the cleaning liquid from splashing out.

[0029] like Figure 5As shown in the figure, the docking sewage discharge mechanism 40 includes a mounting frame 41, a first cylinder 42, a second cylinder 43, and a mounting plate 44. The mounting frame 41 is fixed to one side of the frame 10, and the first cylinder 42 is arranged on the mounting frame 41. The second cylinder 43 is connected to the piston rod of the first cylinder 42, and the mounting plate 44 is connected to the piston rod of the second cylinder 43. A sewage discharge port 441 is provided on the mounting plate 44. The shape and size of the sewage discharge port 441 match the liquid outlet at the bottom of the tank, and it is used to dock with the drain pipe at the bottom of the tank during the cleaning process to discharge the sewage after cleaning.

[0030] Working principle:

[0031] Place the tank to be cleaned on the driving chain 22 of the tank transportation mechanism 20, and ensure that the tank is stable and does not shake. Start the first driving motor 21, and the driving chain 22 starts to move, transporting the tank to directly below the inner wall cleaning mechanism 30 of the tank. Through the second driving motor 313 of the up and down moving assembly 31, lower the cleaning pipe 32 into the tank until the cleaning head 321 approaches the inner wall of the tank. At the same time, the first cylinder 42 and the second cylinder 43 of the docking sewage discharge mechanism 40 act to dock the sewage discharge port 441 with the liquid outlet at the bottom of the tank. Start the third driving motor 331 of the cleaning pipe rotation assembly 33 to make the cleaning pipe 32 start to rotate, and spray high-pressure water or other cleaning liquid through the cleaning head 321 to comprehensively clean the inner wall of the tank. During the cleaning process, the sewage is discharged through the liquid outlet at the bottom of the tank and the sewage discharge port 441 of the docking sewage discharge mechanism 40. After the cleaning is completed, turn off the third driving motor 331 of the cleaning pipe rotation assembly 33 to stop spraying the cleaning liquid. Then, through the second driving motor 313 of the up and down moving assembly 31, lift the cleaning pipe 32 to the initial position. At the same time, the first cylinder 42 and the second cylinder 43 of the docking sewage discharge mechanism 40 act to separate the sewage discharge port 441 from the liquid outlet at the bottom of the tank. Restart the first driving motor 21 to continue transporting the cleaned tank forward to the next station for subsequent processing or storage.

[0032] The large tank inner wall cleaning device of this embodiment realizes the all-round cleaning of the tank inner wall through the rotation and up and down movement of the cleaning pipe, effectively solving the problem of poor cleaning effect caused by the inability of the cleaning head to rotate in the traditional cleaning method. The entire cleaning process has a high degree of automation and only requires simple operation to complete the cleaning task, reducing the manual labor intensity. The design of the docking sewage discharge mechanism enables the sewage generated during the cleaning process to be discharged in a timely manner, avoiding environmental pollution caused by the sewage. The large tank inner wall cleaning device provided in this embodiment has the advantages of high cleaning efficiency, simple operation, compact structure, and environmental protection and energy saving, and can be widely applied to the tank cleaning operations in fields such as chemical industry and pharmacy.
