A dual-shaft motor 25 is installed at the end of the heating chamber shell 3 away from the mixer 17. When the dual-shaft motor 25 is working, it drives the sliding frame 22 to move back and forth through the transmission mechanism.

[0026] When the heat transfer oil heating device is working, the heat transfer oil in the heat transfer oil tank 7 is transported to the first connecting frame 4 through the conveying mechanism, and then enters the second connecting frame 5 through the heat exchange tube 6, and is discharged through the oil outlet pipe 12. At the same time, the fan 14 draws air into the preheating box 13. The combustion exhaust gas in the heating chamber shell 3 enters the preheating box 13 through the exhaust pipe 16 to preheat the cold air. The preheated air and exhaust gas are mixed and enter the mixer 17. At the same time, fuel enters the mixer 17, so that the air, exhaust gas and fuel are mixed and then enter the heating chamber shell 3 for combustion. When there are many impurities on the outer surface of the heat exchange tube 6, the dual-shaft motor 25 drives the sliding frame 22 to move back and forth through the transmission mechanism.

The external dimensions of the slider 28 are matched, the tooth pitch of the worm wheel 30 and the worm 31 is equal, and the worm wheel 30 and the worm 31 mesh. When the dual-axis motor 25 is working, it drives the worms 31 at both ends to rotate. The worms 31 drive the worm wheel 30 to rotate through meshing. The worm wheel 30 drives the reciprocating screw 29 to rotate. The reciprocating screw 29 drives the slider 28 to move back and forth in the slide groove 27 through the threaded connection. In turn, it drives the sliding frame 22 to clean the outer surface of the heat exchange tube 6 through reciprocating movement. Through this transmission mechanism, the upper and lower ends of the sliding frame 22 can be driven at the same time, which can drive the sliding frame 22 to move back and forth smoothly and avoid the sliding frame 22 from shaking when sliding.

[0029] Working Principle: This high-efficiency thermal oil heating device works by conveying thermal oil from the thermal oil tank 7 to the first connecting frame 4 via a conveying mechanism. The oil then passes through the heat exchange tube 6 into the second connecting frame 5, and is discharged through the oil outlet pipe 12. Simultaneously, the fan 14 draws air into the preheating box 13. Combustion exhaust gas from the heating chamber shell 3 enters the preheating box 13 through the exhaust pipe 16 to preheat the cold air. The preheated air mixed with the exhaust gas enters the mixer 17, along with fuel. This mixture of air, exhaust gas, and fuel then enters the heating chamber shell 3 for combustion. When there are many impurities on the outer surface of the heat exchange tube 6, the dual-shaft motor 25 drives the sliding frame 22 to reciprocate via a transmission mechanism. When in operation, the annular scraper 24 scrapes off the impurities attached to the outside of the heat exchange tube 6, cleaning the outer surface of the heat exchange tube 6 and thus improving the heat exchange efficiency of the heat exchange tube 6. This effectively improves the heating efficiency of the heat transfer oil. When the dual-shaft motor 25 is working, it drives the worm gears 31 at both ends to rotate. The worm gears 31 drive the worm wheel 30 to rotate through meshing. The worm wheel 30 drives the reciprocating screw 29 to rotate. The reciprocating screw 29 drives the slider 28 to move back and forth in the slide groove 27 through the threaded connection. This in turn drives the sliding frame 22 to clean the outer surface of the heat exchange tube 6 through reciprocating movement. Through this transmission mechanism, the upper and lower ends of the sliding frame 22 can be driven simultaneously, enabling the sliding frame 22 to move back and forth smoothly and avoiding shaking when the sliding frame 22 slides.
