[0002] At present, hot air furnaces are used in the recycling process of waste tires. The application of hot air furnaces is mainly reflected in the heating method of waste tire refining equipment. The traditional heating method is to use a burner, but with modern technological improvements, the heating method has been changed to a hot air furnace. Hot air furnaces can be divided into solid, liquid and gas fuel hot air furnaces according to the fuel. Among them, carbon black hot air furnaces are the more common type of solid fuel hot air furnaces. The carbon black hot air furnace is a device that uses carbon black exhaust as fuel and heats the air through the heat generated by combustion to generate hot air.

[0003] During the operation of the existing carbon black hot blast furnace, carbon black dust is generated. If the dust is not handled, it will cause damage to the equipment and the environment. Therefore, in order to protect the equipment and improve environmental protection standards, a filter is used inside the carbon black hot blast furnace to capture and filter the dust. However, after the filter in the existing carbon black hot blast furnace has been used for a period of time, a large amount of debris is easily attached to the filter surface, affecting the ventilation effect of the filter. When cleaning the debris attached to the filter surface of the filter, it needs to be disassembled and cleaned, which not only causes trouble to the staff, but also requires shutdown for cleaning, thereby reducing the convenience of maintenance of the carbon black hot blast furnace.

[0038] After using for a period of time, when it is necessary to clean the debris attached to the left side of the filter 409, the drive motor 503 can be started to rotate the worm 504, and then the worm 504 drives the worm wheel 506, the vertical shaft 505 and the drive disc 507 to rotate, and then the drive disc 507 drives the toggle column 509 to rotate, and the rotating toggle column 509 drives the driving block 508 and the cleaning brush 502 to move back and forth, thereby cleaning the debris attached to the left side of the filter 409; the cleaned debris falls into the collection box 403.

[0039] When cleaning the debris attached to the left side of the filter 409, the manual turntable 5011 can also be directly rotated by the rotating handle on the front end of the manual turntable 5011, which can also drive the worm 504 to rotate, and finally drive the cleaning brush 502 to move back and forth to achieve the cleaning effect, so that the automatic cleaning mechanism 5 can be operated manually and automatically, thereby improving the flexibility of the automatic cleaning mechanism 5.

[0040] When it is necessary to clean the debris collected in the collection box 403, the two fasteners 406 can be squeezed in opposite directions at the same time to separate the two fasteners 406 from the fastening notches 408, and then the box door 401 is rotated open to remove the collection box 403 from the filter box 4 for cleaning.
