By using the cleaning mechanism 17 and the cleaning mechanism 6 in coordination, cleaning is performed first and then cleaning, which can improve the efficiency of cleaning the inner wall of the tubular pyrolysis furnace 1.

[0033] In this embodiment, the power mechanism 19 is composed of a transmission 8 and a motor 7. The transmission 8 is installed on the upper side of the insulation mechanism 18, and the motor 7 is installed on the upper side of the transmission 8. When the power mechanism 19 is in use, the motor 7 is turned on by a switch, and the motor 7 will drive the shaft 16 to rotate through the transmission 8 to provide power to the shaft 16.

[0039] In this embodiment, the upper, middle and lower sides of the scraper 11 are installed on the upper side of the one-way bearing 14, and the one-way bearing 14 is installed on the upper side of the shaft 16. The one-way bearing 14 is set to be in an active state when the shaft 16 rotates forward, and in a locked state when the shaft 16 rotates reversely. When the shaft 16 drives the stirring blade 13 to rotate forward, the scraper 11 does not move. When cleaning, the shaft 16 rotates reversely, which will drive the scraper 11 to move.
