Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, specifically relating to a cleaning machine for cleaning the interior of a tank. Background Technology

[0002] Tanks include various types of containers such as reaction vessels, storage tanks, and fermentation tanks. Due to process requirements, many containers are equipped with coils, tube heat exchangers, and heat exchange tube bundles. The tubes in the tank are attached to the inner wall of the container, and the height of the tubes is generally two-thirds of the height of the straight cylindrical part of the container. After use, the tank and tubes need to be cleaned.

[0003] In existing technologies, tank cleaning machines typically use a cleaning hose that extends directly into the tank from the top opening. However, many existing tanks have an arc-shaped top structure, and the cleaning port is often located on this arc, resulting in an inclined position. This makes it difficult for existing cleaning machines to insert the cleaning hose into the port, affecting the cleaning effect or even preventing cleaning altogether, thus reducing their practicality.

The rotating structure 90 is disposed on the sliding seat 31 and connected to the mounting base 80, and is used to drive the mounting base 80 to rotate. The mounting base 80 has a through hole through which the cleaning pipe 70 passes. In this embodiment, the mounting base 80 is disposed on the sliding seat 31, and one end of the fixing rod 34 is slidably connected to the mounting base 80. The rotating structure 90 is disposed on the sliding seat 31 and connected to the mounting base 80, and is used to drive the mounting base 80 to rotate. The mounting base 80 drives the fixing rod 34 to rotate, thereby the fixing rod 34 drives the cleaning pipe 70 to rotate, and the cleaning pipe 70 drives the cleaning nozzle to rotate, achieving all-round cleaning of the tank.

[0037] In some embodiments, please refer to Figure 4 The rotating structure 90 includes a second drive motor 91, a drive gear, and an auxiliary gear 92.

In this embodiment, the drive gear is connected to the power output end of the second drive motor 91 and rotatably connected to the sliding seat 31, so the second drive motor 91 drives the drive gear to rotate, and the auxiliary gear 92 meshes with the drive gear for transmission, thus the drive gear drives the auxiliary gear 92 to rotate. The auxiliary gear 92 is connected to the mounting base 80, which in turn drives the mounting base 80 to rotate. The mounting base 80 drives the fixing rod 34 to rotate, which in turn drives the cleaning pipe 70 to rotate. The cleaning pipe 70 drives the cleaning nozzle to rotate, achieving all-round cleaning of the cleaning tank.

[0038] Specifically, the fixed rod 34 rotates at an angle of less than 60°, so it will not damage the cleaning tube 70 during rotation, nor will it affect the flow of cleaning fluid through the cleaning tube 70.

The connecting rod 332 is connected to the telescopic end of the drive cylinder 331. Two swing members 333 are provided, each hinged to one end of the connecting rod 332, and both swing members 333 are hinged to the fixed rod 34. The mounting base 80 has a sliding hole adapted to the connecting rod 332. In this embodiment, the connecting rod 332 is connected to the telescopic end of the drive cylinder 331, and its two ends are slidably connected to the mounting base 80, thereby driving the drive cylinder 331 to drive the connecting rod 332 to slide. There are two swing members 333. The two swing members 333 are respectively hinged to the two ends of the connecting rod 332, and both swing members 333 are hinged to the fixed rod 34. Thus, the connecting rod 332 drives the swing members 333 to rotate, the swing members 333 drive the fixed rod 34 to move, and then the fixed rod 34 drives the cleaning pipe 70 to move.

[0040] Furthermore, the fixing rod 34 can be a telescopic rod. By adjusting the length of the fixing rod 34, the position of the cleaning nozzle inside the tank can be adjusted to achieve cleaning of different parts of the tank and ensure the cleaning effect.
