DETAILED DESCRIPTION

[0013] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0014] In conjunction with the accompanying drawings, a steam-cleaning device for a distillation kettle includes a shell 1, a quick-release blind plate 2 is arranged on the top of the shell 1, a connecting flange 3 is fixedly arranged on the top of the quick-release blind plate 2, a spray pipe 4 is fixedly arranged on the inner wall of the connecting flange 3, the spray pipe 4 is externally connected to a steam generator, a first connecting pipe 5 is fixedly arranged on the outer ring of the spray pipe 4 near the top, a second connecting pipe 6 is fixedly arranged on the bottom of the spray pipe 4, the ends of the first connecting pipe 5 and the second connecting pipe 6 are both rotatably connected to a spray head 7, and a drain valve 9 is provided at the bottom of the shell 1.

[0015] The spray pipe 4 is close to the inner wall of the shell 1, the first connecting pipe 5 is tilted downward, and the second connecting pipe 6 is tilted upward. The central axes of the first connecting pipe 5 and the second connecting pipe 6 are located on the same horizontal plane as the central axis of the shell 1. This structural design is conducive to increasing the spraying area.

[0016] The nozzles 701 are arranged in an array on the outer circle of the nozzle 7, and the installation direction of the nozzles 701 deviates from the axis of the nozzle 7, so that the nozzle 7 can be driven to rotate when the steam is sprayed out.

[0017] The inner ring of the nozzle 7 abuts against the corresponding outer rings of the first connecting tube 5 and the second connecting tube 6. The outer rings of the first connecting tube 5 and the second connecting tube 6 are fixedly provided with mounting grooves 601. The nozzle 7 is provided with slide grooves 702.
