Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0033] See also Figure 1-11 , an embodiment of the present invention provides a graphene heating system for use in a paint baking room, comprising a main room body 1, a plurality of graphene heating components 7 are hung on the side walls of the main room body 1, and baseboard components 9 for facilitating air entry are fixedly connected to the four corners of the inner bottom of the main room body 1, a gas distribution plate 5 is fixedly connected to the inner top of the main room body 1, the top of the graphene heating component 7 is connected to the gas distribution plate 5 through an air inlet pipe 6, and the bottom end of the graphene heating component 7 is connected to the baseboard component 9 through an air outlet pipe 8, a dustproof shell 2 and an air intake hood 4 are fixedly connected to the top of the main room body 1 from bottom to top, the side of the air intake hood 4 is connected to the baseboard component 9 through an air return pipe 10, and the air return pipe 10 passes through the main room body 1, a filter top cotton 13 is provided inside the dustproof shell 2, an exhaust fan 12 is provided inside the air intake hood 4, the exhaust fan 12 is located on the upper side of the filter top cotton 13, and a through slot 11 for facilitating air entry is provided on the top of the main room body 1.

[0034] During the use of the present invention, when it is necessary to spray and paint the car that has entered the main body 1, the paint spraying equipment is first used to spray the surface of the car, and then the graphene heating coating 73 and the suction fan 12 are connected to the external power supply, and the graphene heating coating 73 and the suction fan 12 are respectively energized, and then the graphene heating coating 73 is energized to heat up, and respectively conducts heat to the microcrystalline glass heating plate 74 and the heat-conducting silicone layer 75, and then the microcrystalline glass heating plate 74 conducts heat and generates far-infrared rays, and then the far-infrared rays generated on the microcrystalline glass heating plate 74 are The infrared rays pass through the metal mesh 72 and enter the main room 1, and heat and dry the paint on the surface of the car, achieving the purpose of far-infrared heating of the paint on the surface of the car, and the paint baking uniformity is high. Moreover, the far-infrared rays entering the main room 1 also heat and increase the temperature inside the main room 1, and the heating speed is fast. The heat generated by the heat-conducting silicone layer 75 is transferred to the heat-conducting metal box 76, thereby heating the heat-conducting metal box 76, and then heating the air inside the heat-conducting metal box 76. The operation of the suction fan 12 drives the air flow, and then the air inside the main room 1 is heated. The air from the upper part passes through the circular hole 911, the U-shaped groove 1 913 and the U-shaped groove 2 921 into the air flow channel formed between the upper cover 91 and the bottom plate 92, and then enters the return air pipe 10, and enters the air inlet cover 4 and the dustproof shell 2 in sequence, and then filters the dust from the air through the filter top cotton 13, and then the air passes through the through groove 11 and enters the gas distribution plate 5, and then is discharged into the main room 1 through the multiple air outlet holes 51 on the gas distribution plate 5, thereby realizing the control of the flow direction of the air and the purpose of circulating the air. In addition, the gas The excess air in the distribution plate 5 enters the heat-conducting metal box 76 through the air inlet pipe 6 and is heated in the heat-conducting metal box 76. The heated air is then sent into the air flow channel through the air outlet pipe 8, where it is mixed with the air entering the air flow channel from the main room body 1, thereby achieving secondary heating of the air inside the main room body 1. The heated air then passes through the return air pipe 10 and flows back into the main room body 1 again, ensuring that the temperature inside the main room body 1 is constant. At the same time, the waste heat generated by the heating of graphene is recovered and reused, thereby achieving the purpose of energy saving and environmental protection.

[0035] As a real-time of the present invention: an air flow inlet is connected to the tail end of the return air pipe 10, and the air flow inlet is connected to a solenoid valve, and the solenoid valve is controlled by an external control device. When the interior of the paint booth needs to be exhausted, the air flow inlet is opened, and then the outside air enters the return air pipe 10, the air intake hood 4, the through groove 11 and the gas distribution plate 5 in sequence through the suction fan 12, and enters the interior of the paint booth, and then the interior of the paint booth is exhausted.

Then the microcrystalline glass heating plate 74 and the thermally conductive silicone layer 75 generate far-infrared rays. The far-infrared rays generated by the microcrystalline glass heating plate 74 pass through the metal mesh 72 and are emitted into the main room body 1, thereby quickly heating the temperature inside the main room body 1 and drying the paint on the surface of the car, thereby achieving the purpose of uniformly heating and drying the paint on the surface of the car. The far-infrared rays generated by the thermally conductive silicone layer 75 are emitted to the thermally conductive metal box 76 and heat the thermally conductive metal box 76, thereby achieving the purpose of recycling the waste heat generated on the back side of the graphene heating coating 73.

The far-infrared rays are then directed to the heat-conducting metal box 76, thereby heating the heat-conducting metal box 76. The air in the gas distribution plate 5 enters the heat-conducting metal box 76 through the air inlet pipe 6, thereby heating the air in the heat-conducting metal box 76. The heated air then enters the air outlet pipe 8 and enters the air flow channel inside the baseboard assembly 9, thereby mixing with the air entering the air flow channel from the main room body 1 and heating this part of the air, thereby achieving the purpose of waste heat utilization.

[0042] During use of the present invention, the wall-mounted plate 16 is fixed to the side wall of the main room body 1, and the connecting plate 77 is fixed in the groove of the main shell body 71. Then, the wall-mounted groove 771 on the connecting plate 77 is snapped into the wall-mounted protrusion 161 on the wall-mounted plate 16, so that the main shell body 71 can be quickly installed and removed conveniently. The disassembly is easy and convenient. The design of multiple wall-mounted protrusions 161 makes it possible to wall-mount the main shell body 71 at different heights. Based on the design of different heights, it is convenient to evenly heat and increase the temperature inside the main room body 1.
