They are widely used in waste treatment, energy recovery, and resource regeneration, providing support for material reduction, harmlessness, and resource utilization. Pyrolysis furnaces are required for pyrolysis in the recycling of photovoltaic modules.

[0003] In existing technologies, pyrolysis furnaces typically have stirring components inside to ensure uniform heating of the materials. However, when traditional stirring components are placed inside the pyrolysis furnace, the high internal temperature can easily damage them. Furthermore, significant heat loss occurs during operation, requiring more energy for continuous heating, which is neither energy-efficient nor environmentally friendly. Therefore, improvements are needed. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes the action of permanent magnets, which drive the movement of magnetic media inside the furnace through a magnetic field, replacing traditional mechanical stirring (which is easily damaged at high temperatures).

An exhaust mechanism 8 and a purification mechanism 9 are provided on the exhaust pipe 13.

[0022] Please see Figure 1 , Figure 2 , Figure 3 The exhaust mechanism 8 includes a fixing strip 81. The fixing strip 81 is fixedly connected inside the exhaust pipe 13. A connecting rod 82 is slidably sleeved inside the fixing strip 81. A first spring 83 is provided on the outside of the connecting rod 82. One end of the first spring 83 is fixedly connected to a fixing block 84, and the other end of the first spring 83 is fixedly connected to the fixing strip 81. By designing the first spring 83, the force of the first spring 83 can act on the fixing block 84. The bottom of the connecting rod 82 is fixedly connected to the fixing block 84, and the top of the connecting rod 82 is fixedly connected to a baffle 85. The baffle 85 contacts the fixing strip 81. A sealing sleeve 86 is fixedly sleeved on the outside of the baffle 85. The sealing sleeve 86 contacts the fixing strip 81 and is slidably connected to the exhaust pipe 13. By designing the sealing sleeve 86, the connection between the baffle 85 and the exhaust pipe 13 can be sealed. By designing the exhaust mechanism 8, the furnace body 1 can be automatically vented.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The purification mechanism 9 includes a connecting frame 91. The connecting frame 91 is slidably fitted inside the exhaust pipe 13. A purification filter element 92 is placed inside the connecting frame 91. A magnetic cover 93 is slidably fitted inside the connecting frame 91, attracting the connecting frame 91 and contacting the purification filter element 92. Multiple through holes 94 are provided inside the magnetic cover 93. A fixing rod 95 is fixedly connected inside the exhaust pipe 13. A second spring 96 is provided on the outside of the fixing rod 95. One end of the second spring 96 is fixedly connected to the exhaust pipe 13. The other end of the spring 96 is fixedly connected to the arc-shaped block 97. By designing the second spring 96, the force of the second spring 96 can be applied to the arc-shaped block 97. The arc-shaped block 97 is slidably sleeved on the outside of the fixing rod 95. The arc-shaped block 97 is slidably connected to the exhaust pipe 13 and the connecting frame 91 respectively.

By designing the arc-shaped groove 98, the arc-shaped block 97 can slide along the arc-shaped groove 98. By designing the purification mechanism 9, the gas can be filtered and purified.

[0024] The specific implementation process of this utility model is as follows: The material to be pyrolyzed and the iron-based magnetic particles are first added into the interior of the furnace body 1 through the feed inlet 5. Then, the hydraulic cylinder 6 drives the sealing cover 7 to move down and close the feed inlet 5. Then, the heating plate 12 works to heat the interior of the furnace body 1. Through the action of the permanent magnet 10, the permanent magnet 10 can drive the movement of the magnetic medium in the furnace through the magnetic field, replacing the traditional mechanical stirring (which is easily damaged at high temperatures). In the pyrolysis furnace, iron-based magnetic particles (such as Fe2O3, nickel powder, which can withstand temperatures above 1000℃) are added as bed material. The array of permanent magnets 10 outside the furnace generates an alternating or rotating magnetic field, which drives the magnetic particles to move up and down / circularly, forming a fluidized state. At the same time, collision heat transfer allows the material to fully contact the heat carrier, improving the pyrolysis efficiency. In addition, the furnace body 1 adopts a closed structure, which can reduce the heat loss inside the furnace body 1 and achieve the purpose of energy saving.

[0025] When the internal pressure of the furnace body 1 is high during pyrolysis, gas will enter the exhaust pipe 13. The gas will push the baffle 85 and the sealing sleeve 86 to move upward. The baffle 85 will drive the connecting rod 82 to move upward. The connecting rod 82 will drive the fixing block 84 to move upward. The fixing block 84 will squeeze the first spring 83, eventually causing the right end of the sealing sleeve 86 to separate from the inner wall of the exhaust pipe 13. At this time, the gas will be discharged through the right end of the exhaust pipe 13, achieving the purpose of depressurizing and venting the inside of the furnace body 1, and improving safety.

[0026] When gas flows inside the exhaust pipe 13, it is filtered and purified by the purification filter element 92, preventing pollution of the external environment when the gas is discharged. When it is necessary to disassemble the connecting frame 91, simply pull the connecting frame 91 upwards. The connecting frame 91 and the arc-shaped block 97 slide relative to each other. The arc surface of the arc groove 98 inside the connecting frame 91 will squeeze and push the arc block 97. The arc block 97 will slide along the fixing rod 95 and squeeze the second spring 96, which can separate the arc block 97 from the arc groove 98. Then the connecting frame 91 can be pulled out from inside the exhaust pipe 13, making it convenient to replace the purification filter element 92 inside the connecting frame 91.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
