[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A ceramic composite nitrogen heating device includes a heating box 1, a support frame 15 installed at the bottom of the heating box 1, and a heat insulation plate installed on the inner wall of the heating box 1 to reduce the heat loss from the heating box 1. An opening 2 is provided on one side of the heating box 1, and an S-shaped heat conduction pipe 3 is provided inside the heating box 1 to allow the heat conduction pipe 3 to have a larger area inside the heating box 1 so that the nitrogen gas can flow through the heat conduction pipe 3 for a longer time, thereby increasing the contact between the nitrogen gas and the hot air. The heat conduction pipe 3 is a vent pipe of ceramic composite material, which improves the heat absorption and pressure resistance of the heat conduction pipe 3.

[0023] Both ends of the heat pipe 3 are installed through the heating box 1 and are fixedly connected to the heating box 1. The inlet pipe 4 and the outlet pipe 5 are connected to the two ends of the heat pipe 3 respectively. A pressure gauge 13 and a one-way valve 14 are installed on the inlet pipe 4 and the outlet pipe 5 respectively. When in use, nitrogen gas is added into the heat pipe 3 from the inlet pipe 4, heated by the heat pipe 3, and then discharged from the outlet pipe 5.

[0024] like Figure 1 and Figure 3 As shown, a sealing plate 6 is provided at the opening 2. The sealing plate 6 is detachably connected to the heating box 1. A connecting seat 10 is provided at the corner of the opening 2. The connecting seat 10 corresponds to the corner of the sealing plate 6. The sealing plate 6 is connected to the connecting seat 10 by bolts, so that the sealing plate 6 can be detachably installed on the opening 2, making it easy to remove the sealing plate 6 from the heating box 1.

[0025] Multiple spaced connecting rods 7 are installed on the side of the sealing plate 6 near the heating box 1, and the connecting rods 7 correspond to the outer side of the heat conduction pipe 3. A heating wire 8 is wound around the connecting rod 7 to heat the air in the heating box 1 and transfer the heat to the heat conduction pipe 3, thereby heating the nitrogen flowing in the heat conduction pipe 3. The wound heating wire 8 can provide a larger heat source for the heat conduction pipe 3 within a certain space, allowing the heat conduction pipe 3 to be heated better and more fully. In actual use, as the sealing plate 6 is disassembled, the connecting rods 7 can be removed together with the sealing plate 6, so as to facilitate the maintenance and replacement of the heating wire 8 wound on the connecting rod 7.

[0026] In order to allow heat pipe 3 to receive heat more effectively, such as Figure 3 and Figure 4As shown, multiple first heat-conducting plates 11 are also provided inside the heating box 1. The cross-section of the first heat-conducting plate 11 is arc-shaped, and the first heat-conducting plate 11 is in close contact with the outer wall of the heat-conducting pipe 3. Multiple second heat-conducting plates 12 are arranged between two adjacent first heat-conducting plates 11. The side of the second heat-conducting plate 12 is fixed to the adjacent first heat-conducting plate 11. The frontal projection of the connecting rod 7 is located between the adjacent second heat-conducting plates 12. The heat-conducting plates can absorb heat and transfer the heat directly to the heat-conducting pipe 3, thereby better heating the nitrogen gas inside the heat-conducting pipe 3.

[0027] Furthermore, multiple guide sleeves 9 are provided inside the heating box 1. One end of the guide sleeve 9 is fixed to the inner wall of the heating box 1, and the other end of the guide sleeve 9 corresponds to the end of the connecting rod 7. After the sealing plate 6 is fixed on the heating box 1, the connecting rod 7 can be placed in the guide sleeve 9, thereby improving the stability of the connecting rod 7 inside the heating box 1.

[0028] Specifically, a control cabinet 16 is installed on the outer wall of the heating chamber 1. The control cabinet 16 contains a controller, which is connected to the heating wire 8, pressure gauge 13, and one-way valve 14 via wires to control the entire heating process. A temperature sensor is installed on the inner wall of the heating chamber 1. The temperature sensor is connected to the controller via wires to monitor the temperature inside the heating chamber 1 in order to control the heating of nitrogen.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
