[0031] Working principle: During operation, when the oxygen sensor 3 detects a low oxygen content, the PCL controller 13 activates the blower 8. The blower 8 delivers air filtered by the filter screen 91 into the furnace body 1, increasing the oxygen content within the furnace body 1. When the carbon sensor 4 detects a low carbon content in the furnace, the PCL controller 13 activates the solenoid valve to control the oxygen and carbon content within the furnace body 1. Simultaneously, the PCL controller 13 activates the second motor 61, which drives the rotating shaft 93 to rotate. The rotating shaft 93 then drives the eccentric wheel 94 to rotate, under the influence of the spring 96. When the eccentric wheel 94 drives the filter screen 91 to move back and forth, it prevents the filter screen 91 from becoming clogged. When it is necessary to disassemble the oxygen sensor 3 and the carbon sensor 4, the second motor 61 is turned on. The second motor 61 drives the threaded rod 62 to rotate. At this time, the threaded rod 62 drives the adjacent threaded block 63 to move in the opposite direction. As a result, the threaded block 63 drives the connecting rod 64 to move in the opposite direction. The connecting rod 64 drives the clamping plate 65 to move in the opposite direction. At this time, the oxygen sensor 3 and the carbon sensor 4 are moved upward, and the probes of the oxygen sensor 3 and the carbon sensor 4 are removed from the exhaust pipe 2 to complete the disassembly.
