specifically, the detector adopts a laser probe, and the position of the cleaning device is detected in real time through the laser probe; in this embodiment, when the laser probe detects the inner wall of dust removal rose box, it indicates that cleaning device moves to the tubular product end, and the controller sends out the stop work instruction this moment.
And when the cleaning step of the cleaning liquid is added and the laser probe detects that the cleaning device moves to the tail end of the pipe, the controller also controls the closing of the infusion valve.
Step S5, pulling the compressed air pipe, and bringing the purging device to the head end of the pipe; or turning the cleaning device 180 degrees;
specifically, when the pipe is obliquely placed, the compressed air pipe is pulled, so that the supporting seat drives the purging device to slide to the head end of the pipe; when the pipe is in a horizontal mode, the cover body of the dedusting filter box can be opened, the cleaning device is turned for 180 degrees after the compressed air pipe is detached, and then the compressed air pipe is connected with the cleaning air pipe;
step S6, starting compressed air, starting the advancing device and the rotating device, and performing secondary purging;
and step S7, after the secondary purging is finished, opening the dedusting filter box, taking out the cleaning device, and treating sundries generated by cleaning.
After the cleaning is finished, the cleaned pipe is lifted off the cleaning platform for subsequent processing or storage.
Compared with the prior art, the pipe inner wall cleaning system and the pipe inner wall cleaning method provided by the invention have the beneficial effects that:
according to the pipe inner wall cleaning system and the pipe inner wall cleaning method, the cleaning device is placed in the pipe, the advancing device drives the blowing device to advance, the rotating device drives the cleaning air pipe to rotate, compressed air is started, and the cleaning air pipe cleans the periphery of the inner wall of the pipe in the advancing process through the compressed air, so that the problem that the inner wall of a long pipe is difficult to clean is solved, the operation is simple, and the energy consumption is low.
The pipe inner wall cleaning system and the cleaning method provided by the invention have the advantages that the dust removal filter boxes are arranged at two ends of the pipe, waste generated by cleaning the inner wall of the pipe groove is swept into the dust removal filter boxes by compressed air and is collected by the dirt collecting box at the bottom of the dust removal filter boxes, and the cleaned objects are convenient to treat without waste gas and waste water treatment pressure; meanwhile, the dust removal filter boxes are arranged at the two ends of the pipe, so that the cleaning wastes can be prevented from flying out of the pipe during cleaning operation, and the operating environment is improved.
The cleaning system and the cleaning method for the inner wall of the pipe can be used for cleaning by combining compressed air and a cleaning agent, and the cleaning effect is better; the pipe is obliquely arranged, so that sundries on the inner wall of the pipe can be conveniently discharged.
