Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, in particular to a waste cracking heating furnace. Background Art

[0002] Organic waste, such as waste rubber, medical infusion tubes, and civil plastic products, is extremely polluting and harmful to the environment. Incineration, landfilling, and other methods of treatment will cause serious secondary pollution to the environment. Therefore, most organic wastes are treated by cracking. Cracking is the process of heating organic solid wastes through a cracking furnace to convert them into liquid or gaseous hydrocarbon compounds and carbon black, thereby achieving comprehensive harmless treatment of organic solid wastes and secondary utilization of organic solid wastes.

[0003] The existing cracking heating furnace is heated by a local burner, which makes the heating furnace unevenly heated and affects the efficiency of cracking. At the same time, the organic waste is prone to coking due to long-term high temperature in a local area, which reduces the quality of the cracking product. In addition, the heating furnace needs to be blown into air for oxygenation. Blowing in cold air will reduce the heating efficiency of the heating furnace, and pre-heating the air through the heater requires additional resources, resulting in waste. Utility Model Content

The side of the shell 2 is fixed to the motor 9 by bolts, the output end of the motor 9 is welded and fixed to the worm 10, one end of the worm 10 is rotatably connected to the inner wall of the shell 2, the inner wall of the shell 2 is welded and fixed to a number of evenly distributed heaters 11, a number of exhaust holes 12 are opened on the top of the shell 2, the exhaust holes 12 are located on both sides of the bottom plate 1, the inside of the shell 2 is connected to the heat exchange box 13 through the exhaust holes 12, the top of the shell 2 is welded and fixed to the heat exchange box 13, the side of the heat exchange box 13 is welded and fixed to the intake pipe 14, one end of the intake pipe 14 is welded and fixed to the heat exchange pipe 15, the upper surface of the bottom plate 1 is welded and fixed to the pump body 16, and the top of the heat exchange box 13 is welded and fixed to the exhaust pipe 17.

[0022] The inside of the sleeve 4 is rotatably connected to the outside of the fixed rod 6 through a sealed bearing, one end of the fixed rod 6 extends to the inside of the heating furnace body 3 and is welded and fixed to the fixed plate 7, the other end of the fixed rod 6 is welded and fixed to the inner wall of the shell 2, one end of the worm 10 is rotatably connected to the inner wall of the shell 2, and the outside of the worm 10 is meshed and connected with the worm wheel 5. The worm 10 is rotated by the motor 9, thereby driving the worm wheel 5 to rotate, and further making the heating furnace body 3 and the sleeve 4 rotate synchronously. The rotation of the heating furnace body 3 makes the heating effect of the heater 11 more uniform, and improves the efficiency of cracking. At the same time as the heating furnace body 3 rotates, due to the fixation of the fixed plate 7 and the stirring plate 8, the stirring plate 8 blocks the material to achieve a stirring and mixing effect, thereby avoiding the situation where the material inside the heating furnace body 3 is locally heated for a long time and causes coking. The heaters 11 are evenly distributed in a linear array on the inner wall of the shell 2. The heater 11 can heat the outside of the heating furnace body 3.

The heat exchange box 13 is connected to the inside of the shell 2 through the exhaust hole 12. The shell 2 is rotatably connected to the outside of the heating furnace body 3. The heat exchange tube 15 is located inside the heat exchange box 13. The heat exchange tube 15 is serpentine. The hot air inside the shell 2 will enter the inside of the heat exchange box 13 from the exhaust hole 12, thereby exchanging heat with the air inside the heat exchange tube 15, realizing the heating of the air in the heat exchange tube 15, and preventing cold air from entering the inside of the shell 2 and reducing the heating efficiency of the heater 11;

[0023] Working principle: When in use, the waste is placed inside the heating furnace body 3, and the worm 10 is rotated by the motor 9, thereby driving the worm wheel 5 to rotate, and further making the heating furnace body 3 and the sleeve 4 rotate synchronously. The rotation of the heating furnace body 3 makes the heating effect of the heater 11 more uniform, and improves the efficiency of cracking. While the heating furnace body 3 rotates, due to the fixation of the fixed plate 7 and the stirring plate 8, the stirring plate 8 blocks the material to achieve a stirring and mixing effect, and avoids the situation where the material inside the heating furnace body 3 is locally heated for a long time and causes coking. The air enters the air inlet pipe 14 through the pump body 16 and is discharged into the shell 2, so that the air inside the shell 2 will enter the heat exchange box 13 through the exhaust hole 12, thereby exchanging heat with the air inside the heat exchange tube 15, and realizing the heating of the air in the heat exchange tube 15, and avoiding cold air from entering the shell 2 to reduce the heating efficiency of the heater 11, effectively enhancing the energy recovery rate of the overall device and reducing resource consumption.
