[0023] See also Figure 1-5The utility model provides a waste lithium battery pyrolysis device, including a furnace body 1, a water storage cylinder 2 is fixed on the top of one side of the outer peripheral surface of the furnace body 1, a filter cylinder 3 is fixed on the bottom of one side of the outer peripheral surface of the furnace body 1, an air pump 4 is fixed on one side of the top surface of the water storage cylinder 2, an air duct 5 is connected and fixed to one side of the air pump 4, one end of the air duct 5 is connected and fixed to the inside of the furnace body 1, and an air guide pipe 6 is connected and fixed to the other side of the air pump 4, a bent pipe 7 is passed through and fixed at the middle position of the water storage cylinder 2, one end of the bent pipe 7 is connected and fixed to the air guide pipe 6, and the other end of the bent pipe 7 extends to the inner cavity position of the filter cylinder 3, a gear ring 9 is fitted on the top of the inner peripheral surface of the furnace body 1, and four circular gears 12 arranged equidistantly and circumferentially are meshed and arranged inside the gear ring 9, and the inside of the circular gear 12 passes through A rotating rod 11 is fixed, and a first motor 8 is fixed on the other side of the top surface of the water storage cylinder 2. The top of the four rotating rods 11 is rotatably connected to the top of the inner cavity surface of the water storage cylinder 2, wherein the top of the rotating rod 11 should pass through the water storage cylinder 2 and be fixed to the output end of the first motor 8, and stirring rods 13 are evenly fixed on both sides of the outer circumference of the rotating rod 11. By adding cold water to the inside of the water storage cylinder 2 and during the transportation of the exhaust gas inside the elbow 7, the heat contained in the exhaust gas in the pipeline can be transferred to the cold water inside the water storage cylinder 2, and by starting the first motor 8, the four rotating rods 11 can drive the stirring rod 13 to rotate, thereby stirring the water in the inner cavity of the water storage cylinder 2, so that the heat transfer to the water inside the water storage cylinder 2 is more uniform.

[0024] Further Figure 2 and Figure 5 As shown, it is worth explaining in detail that a support groove 10 is opened at the position of the inner circumference of the water storage cylinder 2 near the gear ring 9, and a limit ring 22 is slidably inserted inside the support groove 10. The inner circumference of the limit ring 22 is fixed to the outer circumference of the gear ring 9. Due to the interference and support effect between the inner cavity of the support groove 10 and the limit ring 22, the gear ring 9 can be positioned and its movement trajectory during rotation can be limited.

[0025] Further Figure 3 As shown, it is worth explaining in detail that two embedded rings 14 are fixed at the upper and lower ends of the inner cavity surface of the gear ring 9, a cross 16 arranged in a cross shape is fixed at the middle position of the embedded ring 14, and a filter layer 18 is fixed at the middle position between the cross 16 and the inner circumferential surface of the embedded ring 14 at the adjacent position. The two groups of filter layers 18 arranged on the embedded rings 14 at adjacent positions can play a graded filtering role for the exhaust gas entering the inner cavity of the filter cartridge 3, thereby improving the filtering effect.

[0026] Further Figure 2 and Figure 5As shown, it is worth specifically explaining that a movable rod 17 is rotatably connected through the middle position of the two crosses 16, and brush plates 19 are fixedly sleeved at both ends of the outer circumference of the movable rod 17. The surface of the bottom of the brush plate 19 fits with the surface of the filter layer 18 at the adjacent position. A second motor 15 is fixed to one side of the outer circumference of the filter cartridge 3, and a connecting shaft 23 is fixed to the output end of the second motor 15. One side of the connecting shaft 23 extends to a position close to the movable rod 17, and a first bevel gear 20 is fixedly sleeved on the outer circumference of the connecting shaft 23. A second bevel gear 21 is fixedly sleeved at a position close to the first bevel gear 20 on the outer circumference of the movable rod 17. The first bevel gear 20 and the second bevel gear 21 are meshingly connected. By starting the second motor 15, the connecting shaft 23 is rotated, so that the movable rod 17 can be rotated under the meshing action between the second bevel gear 21 and the first bevel gear 20, thereby driving the two brush plates 19 to perform friction and cleaning between the filter layers 18 at adjacent positions, thereby avoiding clogging of the filter layer 18.

[0027] This solution has the following working process: in actual use, when the user needs to process the exhaust gas generated inside the furnace body 1, firstly, the two pipes on one side of the outer peripheral surface of the water storage cylinder 2 are connected to the water delivery pipe and the drainage pipe, and the exhaust gas is allowed to enter the inside of the curved pipe 7 through the air inlet pipe 5 and the air guide pipe 6 by starting the air pump 4, so that the exhaust gas can flow through the curved pipe 7. Due to the structural setting of the curved pipe 7, the time for the exhaust gas to be transmitted inside the curved pipe 7 is prolonged, so that the heat in the exhaust gas can be transmitted to the cold water inside the inner cavity of the water storage cylinder 2, and the first motor 8 is started. , so that one of the rotating rods 11 can rotate, so that one of the circular gears 12 can rotate, so that under the meshing action between the circular gear 12 and the gear ring 9 and the supporting and limiting action of the support groove 10 and the limiting ring 22, the gear ring 9 can rotate, so that under the meshing action between the gear ring 9 and the remaining circular gears 12, the remaining rotating rods 11 can rotate, thereby driving the stirring rods 13 at adjacent positions to rotate, so as to stir the water in the inner cavity of the water storage cylinder 2, thereby The heat can be fully transferred to the water inside the inner cavity of the water storage cylinder 2, so that the heat in the exhaust gas can be fully recovered and utilized. Before the exhaust gas is transported to the inner cavity of the filter cylinder 3 through the elbow 7, the two pipes of the filter cylinder 3 are first sealed. The exhaust gas can be graded and filtered through the two groups of filter layers 18 in the inner cavity of the embedded ring 14 at the adjacent position, thereby improving the filtering effect. By starting the second motor 15 to rotate the connecting shaft 23, the movable rod 17 can be moved under the meshing action between the second bevel gear 21 and the first bevel gear 20. The filter cartridge 3 is rotated to drive the two brush plates 19 to perform a friction cleaning function on the filter layers 18 at adjacent positions, thereby avoiding clogging of the filter layer 18, and connecting the exhaust pipe at the bottom of the filter cartridge 3 to the pump body so that the exhaust gas can be discharged from the exhaust pipe at the bottom of the filter cartridge 3 after filtration. When the dust on the top of the filter layer 18 surface needs to be cleared out of the outside of the filter cartridge 3, the dust is pushed to rotate by the rotation of the brush plate 19, and the pipe on one side of the outer peripheral surface of the filter cartridge 3 is connected to the pump body, so that the dust can be discharged from the outside of the filter cartridge 3 under the suction of the pump body.

[0028] According to the above working process, it can be known that by adding cold water to the inside of the water storage cylinder 2 and during the transportation of the exhaust gas inside the bent pipe 7, the heat contained in the exhaust gas in the pipeline can be transferred to the cold water inside the water storage cylinder 2, and by starting the first motor 8, the four rotating rods 11 can drive the stirring rod 13 to rotate, thereby stirring the water in the inner cavity of the water storage cylinder 2, so that the heat transfer of the water inside the water storage cylinder 2 is more uniform, so that the heat in the exhaust gas can be fully utilized, thereby avoiding the occurrence of heat waste, thereby improving the practicality of the device, and the two groups of filter layers 18 in the inner cavity of the water storage cylinder 2 can be used to grade the exhaust gas. When the second motor 15 is started, the two brush plates 19 are pressed against the surface of the filter layer 18 and rotate to rub and clean it, thereby avoiding the occurrence of blockage in the filter layer 18, thereby ensuring the probability treatment effect of the device on the exhaust gas, thereby further improving the practicality of the device.

[0029] Further as Figure 4 As shown, it is worth explaining in detail that the bottom of the inner cavity surface of the filter cartridge 3 is arc-shaped, and the surface of the bottom of the brush plate 19 is arc-shaped. Due to the shape of the filter cartridge 3, it is possible to prevent the filtered exhaust gas inside the filter cartridge 3 from being discharged from the bottom of the filter cartridge 3. Due to the shape of the brush plate 19, the friction between the filter layer 18 at the adjacent position can be reduced.

[0030] In summary: by adding cold water to the inside of the water storage cylinder 2 and during the process of exhaust gas being transported inside the bent pipe 7, the heat contained in the exhaust gas in the pipeline can be transferred to the cold water inside the water storage cylinder 2, and by starting the first motor 8, the four rotating rods 11 can drive the stirring rod 13 to rotate, thereby stirring the water in the inner cavity of the water storage cylinder 2, so that the heat transfer to the water inside the water storage cylinder 2 is more uniform, so that the heat in the exhaust gas can be fully utilized, thereby avoiding the occurrence of heat waste, thereby improving the practicality of the device, and through the water storage cylinder 2 The two groups of filter layers 18 in the inner cavity can perform graded filtering on the exhaust gas, and when the second motor 15 is started, the two brush plates 19 are pressed against the surface of the filter layer 18 and rotate to clean it by friction, thereby avoiding the filter layer 18 from being blocked, thereby ensuring the probability treatment effect of the device on the exhaust gas, thereby further improving the practicality of the device. The shape setting of the filter cartridge 3 can prevent the filtered exhaust gas inside the filter cartridge 3 from being discharged from the bottom of the filter cartridge 3, and the shape setting of the brush plate 19 can reduce the friction between the filter layer 18 at the adjacent position.

[0031] The air pump 4, the first motor 8 and the second motor 15 can be purchased on the market. The air pump 4, the first motor 8 and the second motor 15 are equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so they are not repeated in the specification.
