Description

Technical Field

[0001] The utility model belongs to the technical field of tank truck inner wall cleaning equipment, in particular to a telescopic tank truck cleaning and suction device. Background Art

[0002] A tank truck is a container for storing and transporting oil products. Petroleum is a viscous emulsion with strong adhesion. After long-term storage, finished oil is prone to sedimentation. Sedimentation accumulation in the tank truck will affect the storage quality of the finished oil. In order to solve the problem of sedimentation in tank trucks after long-term use, the existing technology usually adopts manual cleaning methods to clean and discharge the sediment inside the tank truck, but this method has low cleaning efficiency, high labor intensity for workers, and low cost performance of overall cleaning; some also adopt direct water filling and drainage for cleaning. Although it reduces manual operation, the cleaning effect is not good, and the cost of filling the tank truck with water is high.

[0003] Announcement No. CN202779088U discloses a tank truck cleaning machine that can clean tank trucks and avoid workers directly entering the tank truck for cleaning. Because the current mainstream tank trucks do not have drainage outlets at low points, the cleaning waste liquid of the cleaning machine needs to use a separate cleaning suction pipe to suck away the bottom waste liquid. This suction pipe is a hard pipe that is directly inserted from the manhole to the bottom of the oil tank, and the suction pipe is longer than the cleaning pipe of the cleaning machine. The overall length of the cleaning machine is relatively large, which makes it inconvenient to enter and exit the tank truck.
