[0022] Please refer to Figure 1 The utility model provides a vulcanization furnace, including a furnace body 10, and an explosion-proof furnace door 101 is arranged on one side of the furnace body 10. Since vulcanization generates high-temperature gas pressure inside, the explosion-proof furnace door 101 can improve the safety of use.

[0023] Please refer to Figure 2-4 The inner cavity of the furnace body 10 is provided with a heating circulation system, which includes an inner cover 201, a circulation fan 202, and an electric heater 203. The inner cover 201 is in an inverted U shape, with a number of side ventilation holes 2011 on both sides of the inner cover 201, and a top ventilation hole 2012 on the bottom of the inner cover 201. The two sides of the inner cover 201 with the side ventilation holes 2011 form a ventilation channel 204 with the inner wall of the furnace body 10. The circulation fan 202 is installed on the top of the inner side of the furnace body 10, and the electric heater 203 is installed on both sides of the top of the inner side of the furnace body 10 near the ventilation channel 204. Specifically, when the circulation fan 202 is running, the gas is blown out toward both sides, and the gas is heated when it passes through the electric heater 203. The furnace body 10 There are two trumpet-shaped air outlet ducts 205 on the top of the inner cavity, and the small-diameter ends of the air outlet ducts 205 face the circulation fan 202, and the small-diameter ends of the air outlet ducts 205 face the ventilation channel 204. The heated gas enters the ventilation channel 204 from the air outlet ducts 205 on both sides. The two trumpet-shaped air outlet ducts 205 enable the gas to enter the ventilation channel 204 in a concentrated manner, playing a guiding role; the gas entering the ventilation channel 204 enters the inner cavity of the furnace body 10 from the side ventilation holes 2011 on both sides of the inner cover 201, and is then blown out from the top ventilation holes 2012 on the top of the inner cover 201 to the position of the circulation fan 202. This cycle is repeated to ensure that the object is subjected to a uniform temperature and improve the quality of vulcanization.

[0024] Furthermore, two guide grooves are opened at the bottom of the inner cavity of the furnace body 10, and a slide 105 is slidably set in the guide groove. During operation, the explosion-proof furnace door 101 is opened to pull the slide 105 out along the guide groove. After placing the objects to be vulcanized, the slide 105 is pushed into the interior of the furnace body 10 along the guide groove, which is convenient for taking and placing objects.

[0025] Please refer to Figure 1-2 An air intake regulating valve 103 and an exhaust regulating valve are provided on the top of the outer side of the furnace body 10. Specifically, the air intake regulating valve 103 is used to take air into the furnace body 10, and the exhaust regulating valve is used to discharge the gas in the furnace body 10. The exhaust regulating valve is equipped with a filter. The air intake regulating valve 103 and the exhaust regulating valve play a role in maintaining a constant pressure inside the furnace body 10, while the filter plays a role in filtering the discharged gas.

[0026] Furthermore, an electric control box is installed on the outer side of the furnace body 10, and a temperature sensor is installed on the side wall of the inner cavity of the furnace body 10. The temperature sensor is electrically connected to the electric control box. During vulcanization, the temperature sensor can feedback the temperature conditions inside the furnace body 10 to the electric control box, so that the operator can grasp the internal conditions in real time, further improving the vulcanization qualification rate of the object.

[0027] In addition, hanging rings 102 are installed at the four corners of the upper end surface of the furnace body 10 for hanging the furnace body 10 to facilitate installation.
