[0031] The working principle of the pyrolysis furnace capable of uniformly heating is as follows: when the present application is used, the material fly ash enters the inner furnace 2 from the feed port 14, the pyrolysis electric heater 13 is powered on to heat up, and the heat spreader 11 can uniformly transfer the heat generated by the pyrolysis electric heater 13 to the inner furnace 2, thereby uniformly heating the inner furnace 2 and heating the material fly ash inside; at the same time, the rotating motor drives the first rotating rod 30 and the spiral blade 31 to rotate, and the rotating spiral blade 31 can stir the material fly ash in the inner furnace 2, thereby further uniformly heating the material fly ash; at the same time, nitrogen is transported to the inner furnace 2 through the air inlet pipe 17 to maintain an anaerobic environment during the pyrolysis of the fly ash, and at the same time, the fly ash at the bottom is blown up to prevent the material from accumulating at the bottom and affecting the thermal cracking of the fly ash in the furnace.

[0032] A plurality of lifting ears 28 are fixedly provided on the top of the housing 1, which cooperate with the crane to facilitate the flexible transfer of the present application.

[0033] When the present application is transported, the driving motor 29 drives the second gear 9 to rotate, and the rotating second gear 9 drives the first gear 8 and the first screw 7 to rotate. The rotating first screw 7 causes the slider 6 to move upward in the slide groove 5 until the slider 6 moves to the top of the slide groove 5. The moving slider 6 drives the support leg 3 to slide upward along the outer shell 1. When the slider 6 is located at the top of the slide groove 5, the support leg 3 is completely stored in the outer shell 1. At this time, the size of the present application is greatly reduced, and the space occupied by transportation becomes smaller, which is convenient for transporting the present application.

[0034] When the present application is launched, the driving motor 29 drives the second gear 9 in reverse to rotate, and the rotating second gear 9 drives the first gear 8 and the first screw 7 to rotate. The rotating first screw 7 causes the slider 6 to move downward in the slide groove 5 until the slider 6 moves to the bottom end of the slide groove 5. The moving slider 6 drives the support leg 3 to slide downward along the outer shell 1. When the slider 6 is located at the bottom end of the slide groove 5, the support leg 3 is completely extended from the outer shell 1.

[0035] At the same time, in order to make the present application in a horizontal state when in use, the knob 34 can be rotated to drive the connecting rod 33 and the second bevel gear 27 to rotate, and the rotating second bevel gear 27 causes the third gear 23 and the second screw rod 21 to rotate. The rotating third gear 23 causes the fourth gear 24 and the third screw rod 22 to rotate in the same direction at the same time under the transmission action of the fifth gear 25, so that the height position of the leveling leg 20 in the leveling groove 19 is adjusted by the rotating second screw rod 21 and the third screw rod 22; by individually adjusting the leveling mechanism 18 on each supporting leg 3, the present application can be put in a horizontal state, thereby facilitating the use of the present application.

[0036] In the above embodiment, the present application provides a pyrolysis furnace that can be heated evenly. When the pyrolysis furnace that can be heated evenly is in use, the support legs are moved to the bottom of the shell to facilitate supporting the shell; when transporting the present application, the support legs can be stored on the shell, thereby reducing the space occupied by the present application and facilitating transportation; the second gear can drive all the first gears and the first screw rod to rotate at the same time, and the rotating first screw rod can make the slider move in the slide groove, and the moving slider can drive the support legs to move, so that all the support legs can be driven to move on the shell at the same time through the second gear, thereby facilitating the adjustment of the position of the support legs on the shell; the second bevel gear can drive the first bevel gear and the third gear to rotate; the third gear and the fourth gear are connected by the fifth gear, so that the rotating third gear can drive the fourth gear to rotate in the same direction at the same time, so that the second screw rod and the third screw rod rotate in the same direction at the same time, thereby achieving the purpose of conveniently adjusting the position of the leveling legs.
