[0107] Among them, the initial position and the stop position of the lifting device 2 are both at the lowermost end of the chimney 13. Correspondingly, the initial position and the stop position of the spraying device 4 are also at the lowermost end of the chimney 13.

[0108] Step S32: Control the connection between the hose 5 and the cleaning liquid container 8 through the control box 7.

[0109] Step S33: Control the spraying device 4 to spray the cleaning liquid through the control box 7 to clean the surface of the chimney 13.

[0110] In an embodiment of the automatic spraying method of the anti-rust paint for the tall stainless steel chimney of the present invention, the step S33 may specifically include:

[0111] Step S331: Preset a cleaning time threshold through the control box 7.

[0112] Step S332: Control the opening of the valve corresponding to the cleaning liquid container 8 through the control box 7. The cleaning liquid in the cleaning liquid container 8 is sprayed onto the surface of the chimney 13 through the hose 5, the hollow pipeline of the lifting device 2, the annular hollow pipe 42 of the spraying device 4, and the nozzle 41.

[0113] Step S333: After reaching the cleaning time threshold, the control box 7 controls the closing of the valve corresponding to the cleaning liquid container 8 and controls the opening of the valve corresponding to the air pipe 6 to spray compressed air from the air pipe 6 to dry the surface of the chimney 13.

[0114] Step S34: During the process of the spraying device 4 spraying the cleaning liquid, control the lifting of the lifting device 2 through the control box 7 to drive the spraying device 4 to move up and down through the lifting device 2 to clean the entire surface of the chimney 13.

[0115] Among them, the lifting device 2 is connected to a driving device, and the driving device is connected to the control box 7. The control box 7 controls the driving device to work to realize the lifting of the lifting device. The driving device includes a hydraulic press or a motor. It should be noted that the present invention does not specifically limit the type of the driving device.

[0116] Step S35: After the cleaning is completed, switch the connection of the hose 5 to the rust-proof paint container 9 through the control box 7.

[0117] Step S36: Control the spraying device 4 to spray rust-proof paint through the control box 7 to perform spray painting maintenance on the surface of the chimney 13.

[0118] In an embodiment of the automatic spray painting method of the rust-proof paint for the tall stainless steel chimney of the present invention, step S36 may specifically include:

[0119] Step S361: Preset a maintenance time threshold through the control box 7.

[0120] Step S362: Control the valve corresponding to the cleaning liquid container 8 to close and control the valve corresponding to the rust-proof paint container 9 to open through the control box 7, so that the rust-proof paint in the rust-proof paint container 9 is sprayed onto the surface of the chimney 13 through the hose 5, the hollow pipeline of the lifting device 2, the annular hollow pipe 42 of the spraying device 4 and the nozzle 41.

[0121] Step S363: After reaching the maintenance time threshold, the control box 7 controls the valve corresponding to the rust-proof paint container 9 to close and controls the valve corresponding to the air pipe 6 to open to spray compressed air from the air pipe 6 to dry the surface of the chimney 13.

[0122] In summary, referring to step S333 and step S363, when the spraying device 4 sprays the cleaning liquid or the rust-proof paint, the spraying device 4 needs air to eject and atomize the cleaning liquid or the rust-proof paint. Therefore, after the spraying device 4 works, the air pipe 6 also works to spray compressed air from the air pipe 6. As long as the hose 5 finishes working, that is, after completing the transportation of the cleaning liquid or the rust-proof paint, the air pipe 6 then enters the working state and starts to transport compressed air to realize the function of atomizing the cleaning liquid or the rust-proof paint.

[0123] Step S37: During the process of the spraying device 4 spraying the rust-proof paint, control the lifting of the lifting device 2 through the control box 7 to drive the spraying device 4 to move up and down through the lifting device 2 to perform spray painting maintenance on the entire surface of the chimney 13.

[0124] Step S38: Determine whether the number of round trips of the lifting device 2 meets the end condition. If it meets, end the automatic spray painting work; if it does not meet, repeat the steps of spraying the cleaning liquid first and then the rust-proof paint.

[0125] During the operation of the spraying device 4, the up-and-down movement of the spraying device 4 is realized by the up-and-down movement of the lifting device 2, so as to realize the self-cleaning and painting maintenance of the entire chimney 13.

[0126] The automatic spraying method of the rust-proof paint for the tall stainless-steel chimney provided by the embodiment of the present invention controls the working states of the spraying device, the lifting device, the hose, the air pipe, the cleaning liquid container and the rust-proof paint container through the control box, so as to automatically clean the surface of the chimney and automatically spray the rust-proof paint on the surface of the chimney, so as to realize the automatic cleaning of the chimney and the automatic spraying of the rust-proof paint, and the automatic painting maintenance can be carried out during the production gap; it can efficiently and automatically complete the self-cleaning and painting maintenance of the tall chimney, ensuring personal safety and the safe operation of the equipment, so as to solve the problems of personal safety and the safe operation of the equipment faced by production enterprises.
