The principle is to install a group of heaters inside the furnace body. After power is turned on, the heaters emit heat, and the material is heated and kept warm by controlling the heat.

[0003] In the prior art, during the production and processing of heat pipes, an annealing furnace is required to process the heat pipes. However, during the annealing process, the oil will vaporize due to the high temperature and adhere to the inner wall of the pot cover. After the annealing is completed, the pot cover is cooled, and the oil mist condenses and drips, which can easily cause oxidation corrosion to the heat pipe, reduce the quality of the finished product of the heat pipe, and is not conducive to the production and processing of the heat pipe.

[0004] Therefore, how to achieve this is a technical problem that needs to be solved urgently in the industry. Utility Model Content

[0006] The utility model provides an anti-drip oil structure of a heat pipe annealing furnace, comprising a furnace cover, an inner connecting ring and an outer connecting ring arranged at the top of the annealing furnace body, wherein a connecting ring plate is fixedly connected to the bottom of the outer surface of the furnace cover, and the lower surface of the connecting ring plate is detachably connected to the inner connecting ring;

[0007] The outer connecting ring cover is arranged outside the inner connecting ring, and a plurality of support rods are fixedly connected between the outer side surface of the inner connecting ring and the inner wall surface of the outer connecting ring, and the plurality of support rods are evenly distributed and arranged in a circular shape along the surface of the inner connecting ring;

[0008] A grille net is fixedly connected to the upper surface of the support rod, and a high-temperature resistant barrier layer is fixedly connected to the upper surface of the grille net.

[0009] Preferably, a sealing member is fixedly connected to the top of the annealing furnace body, and a sealing groove adapted to the sealing member is formed on the lower surface of the inner connecting ring.

[0010] Preferably, a placement frame for placing heat pipes is fixedly connected to the bottom of the inner wall of the annealing furnace body.

[0011] Preferably, a connecting shaft is fixedly connected to the top of the furnace cover, and a plurality of hanging ears are fixedly connected to the surface of the connecting shaft.

[0013] Preferably, a plurality of bolts are arranged on the surface of the connecting ring plate, a plurality of mounting blocks are fixedly connected to the side wall of the inner connecting ring, and threaded holes matching the bolts are opened on the surface of the mounting blocks.

[0014] According to the utility model, after the oil temperature is increased and vaporized, the oil mist rises through the inside of the inner connecting ring and adheres to the inner wall surface of the furnace cover. After the annealing process is completed, the temperature of the furnace cover surface is reduced, the adhered oil mist condenses and flows along the curvature of the furnace cover surface to the outer ring edge of the furnace cover and drips under the influence of gravity. The dripping liquid is blocked by the high-temperature resistant barrier layer to avoid dripping and contacting the surface of the heat pipe after annealing, thereby avoiding oxidation corrosion on the surface of the heat pipe, improving the quality of the finished product after the heat pipe is annealed, and facilitating the production, processing and use of the heat pipe.

[0023] The outer connecting ring 2 is covered on the outside of the inner connecting ring 1 , and a plurality of support rods 3 are fixedly connected between the outer side surface of the inner connecting ring 1 and the inner wall surface of the outer connecting ring 2 . The plurality of support rods 3 are evenly distributed and arranged in a circular shape along the surface of the inner connecting ring 1 .

[0024] A grille mesh 5 is fixedly connected to the upper surface of the support rod 3 , and a high temperature resistant barrier layer 4 is fixedly connected to the upper surface of the grille mesh 5 .

[0025] After the oil temperature rises and vaporizes, the oil mist rises through the inside of the inner connecting ring 1 and adheres to the inner wall surface of the furnace cover 9. When the annealing process is completed, the temperature of the surface of the furnace cover 9 decreases, and the attached oil mist condenses and flows along the curvature of the surface of the furnace cover 9 to the outer ring edge of the furnace cover 9 and drips under the influence of gravity.

[0026] The dripping liquid is blocked by the high temperature resistant barrier layer 4 to prevent it from dripping and contacting the annealed surface of the heat pipe, thereby preventing oxidation corrosion on the surface of the heat pipe, improving the quality of the finished product after annealing, and facilitating the production, processing and use of the heat pipe.

[0027] The support rods 3 and the grid mesh 5 support the high temperature resistant barrier layer 4, thereby improving the supporting effect of the high temperature resistant barrier layer 4 and further improving the stability during the barrier process.

[0028] Furthermore, a sealing member 7 is fixedly connected to the top of the annealing furnace body 6 , and a sealing groove 18 adapted to the sealing member 7 is formed on the lower surface of the inner connecting ring 1 .

[0029] After the inner connecting ring 1 is placed on the top of the annealing furnace body 6 , the sealing member 7 is embedded in the sealing groove 18 to improve the sealing performance of the furnace cover 9 to the top of the annealing furnace body 6 .

[0035] Furthermore, a plurality of bolts 17 are disposed on the surface of the connecting ring plate 14 , a plurality of mounting blocks 15 are fixedly connected to the side wall of the inner connecting ring 1 , and threaded holes 16 adapted to the bolts 17 are opened on the surface of the mounting blocks 15 .

[0036] After the bolts 17 are threadedly connected with the threaded holes 16 , the inner connecting ring 1 can be installed on the lower surface of the connecting ring plate 14 through the connection of the threaded holes 16 for use.

[0037] During operation, after the oil temperature rises and vaporizes, the oil mist rises through the inside of the inner connecting ring 1 and adheres to the inner wall surface of the furnace cover 9. When the annealing process is completed, the temperature of the surface of the furnace cover 9 decreases, and the attached oil mist condenses and flows along the curvature of the surface of the furnace cover 9 to the outer ring edge of the furnace cover 9 and drips under the influence of gravity. The dripping liquid is blocked by the high-temperature resistant barrier layer 4 to avoid dripping and contacting the annealed heat pipe surface, thereby avoiding oxidation corrosion on the heat pipe surface, improving the quality of the finished product after the heat pipe is annealed, and facilitating the production, processing and use of the heat pipe.
