DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The aluminum nitride sintering furnace is a device used for high-temperature sintering of raw materials required for nitriding furnace processing, so as to change its processing state by high temperature so as to meet the production and processing requirements. It has been widely used in the field of nitriding furnace processing, so the aluminum nitride powder sintering furnace is needed. When using this equipment, the heating temperature of the furnace body 301 needs to be strictly controlled to avoid exceeding the limit temperature that the material can withstand to prevent equipment damage or safety accidents. At least one staff member is required to operate it during use. The staff must abide by the operating procedures, ensure their own safety, avoid direct contact with high-temperature components or heat sources, and use heat-resistant gloves, goggles and other personal protective equipment.

[0020] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: an aluminum nitride powder sintering furnace, comprising a base plate 1, a feeding mechanism 2 is arranged on the top of the base plate 1, the feeding mechanism 2 comprises a feeding box 201, a feeding funnel 202 is fixedly connected to the top of the feeding box 201, a heat exchange mechanism 3 is arranged at the bottom of the feeding mechanism 2, the heat exchange mechanism 3 comprises a furnace body 301, the bottom of the furnace body 301 is connected to the base plate 1, a heat conducting plate 302 is slidably connected to the inner wall of one side of the furnace body 301, one side of the furnace body 301 is electrically connected to a controller 4, and the side of the furnace body 301 away from the controller 4 is electrically connected to a temperature alarm 5.

[0021] It should be noted that during use, the powder material first enters the loading box 201 through the feeding funnel 202, and then the loading mechanism 2 controls the time for the material to enter. At the same time, the temperature inside the furnace body 301 is controlled by the controller 4. When the temperature is too high, the temperature alarm 5 sends an alarm and the heat exchange mechanism 3 cools down the furnace body 301. The controller 4 can monitor and adjust the temperature of the furnace body 301 in real time to ensure the temperature control accuracy during the powder sintering process and improve product quality.

[0022] like Figure 2 As shown, a servo motor 203 is installed at the bottom of the loading box 201, and the bottom of the servo motor 203 is connected to the furnace body 301. A connecting rod 204 is fixedly connected to the output end of the servo motor 203, and a spiral plate 205 is fixedly connected to the outer wall of the connecting rod 204. A through hole is opened on one side of the loading box 201, and a discharge pipe 206 is fixedly connected in the through hole.

[0023] It should be noted that during use, the powder material first enters the loading box 201 through the feed funnel 202, and then the servo motor 203 drives the connecting rod 204 to rotate while driving the spiral plate 205 to rotate, and pushes the material into the furnace body 301 through the discharge pipe 206. The loading mechanism 2 adopts the design of the servo motor 203 and the spiral plate 205, which can realize continuous and stable pushing of powder into the furnace body 301, ensuring the continuity and efficiency of the production process.

[0024] like Figure 3 As shown, heating tubes 303 are installed on the inner walls of both sides of the furnace body 301, a plurality of through holes are opened on one side of the top of the furnace body 301, ventilation tubes 304 are fixedly connected in the through holes, a fan 305 is installed on the inner wall of the ventilation tube 304, a cold water tank 306 is arranged on one side of the furnace body 301, the cold water tank 306 is connected to the bottom plate 1, a water pump 307 is installed at one end of the cold water tank 306, a heat exchange tube 308 is fixedly connected to the output end of the water pump 307, a drain pipe 309 is fixedly connected to one end of the heat exchange tube 308, and a valve 310 is installed on the top of the drain pipe 309.

[0025] It should be noted that during use, the heating tube 303 first heats the inside of the furnace body 301 through the heat conduction plate 302, and at the same time the water pump 307 starts to input the cold water in the cold water tank 306 into the heat exchange tube 308. When the temperature inside the furnace body 301 is too high, the fan 305 starts to cool the inside of the furnace body 301 through the ventilation tube 304. When the water temperature in the heat exchange tube 308 is high, the valve 310 controls the drain pipe 309 to discharge it. The heat exchange mechanism 3 can recycle the heat absorbed in the cooling water to avoid energy waste.

[0026] During use, the powder material first enters the loading box 201 through the feeding funnel 202, and the material is pushed into the furnace body 301 through the discharge pipe 206. When the material enters the furnace body 301, the heating tube 303 heats the inside of the furnace body 301 through the heat conduction plate 302. When the temperature inside the furnace body 301 is too high, the fan 305 starts to cool the inside of the furnace body 301 through the ventilation pipe 304. When the water temperature in the heat exchange tube 308 is high, the valve 310 controls the discharge through the drain pipe 309, so that the heat absorbed in the cooling water can be recycled to avoid energy waste.
