[0026] See also Figure 1-7 As shown, an embodiment of the utility model provides a furnace body structure of an environmentally friendly incinerator, including a furnace barrel 1, a top surface of the furnace barrel 1 is provided with a feeding port 11 and a smoke exhaust port 12, a bottom surface of the furnace barrel 1 is provided with a discharge port 13, materials are fed into the furnace barrel 1 from the feeding port 11 for incineration, waste gas generated by incineration is discharged from the smoke exhaust port 12 for treatment, and waste residue generated by incineration is discharged from the discharge port 13.

[0027] See also Figure 2As shown, a stirring and cleaning structure 2 is provided in the furnace barrel 1. The stirring and cleaning structure 2 can stir the materials during the material incineration process, and can clean the inner wall of the furnace barrel 1 after the incineration is completed. The cleaning range includes the bottom wall and side wall of the furnace barrel 1. The stirring and cleaning structure 2 includes a motor 28, a rotating shaft 21, a connecting rod 22, a scraper 23 and a telescopic mechanism. Among them, the motor 28 is fixedly arranged at the center of the top surface of the furnace barrel 1, and the rotating shaft of the motor 28 is fixedly connected to the top of the rotating shaft 21 located in the furnace barrel 1. The rotating shaft of the motor 28 drives the rotating shaft 21 to rotate in the furnace barrel 1, and the stirring rod on the rotating shaft 21 stirs the material. The telescopic mechanism is arranged inside the rotating shaft 21, one end of the connecting rod 22 is movably inserted in the rotating shaft 21 and connected to the telescopic mechanism, and the other end of the connecting rod 22 is fixedly connected to the scraper 23. The telescopic mechanism is used to drive the scraper 23 to leave or adhere to the inner wall of the furnace barrel 1. When materials are burned in the furnace barrel 1, the scraper 23 is in a state of leaving the inner wall of the furnace barrel 1, reducing the wear of the scraper 23 and the inner wall of the furnace barrel 1; when there is no material burning in the furnace barrel 1, the telescopic mechanism drives the scraper 23 to adhere to the inner wall of the furnace barrel 1, and the scraper 23 can clean up the garbage attached to the inner wall of the furnace barrel 1 as the rotating shaft 21 rotates.

[0028] See also Figure 4 As shown, the telescopic mechanism includes a double-headed electric push rod 25, a movable block 26, a guide cylinder 29 and a spring 24. The double-headed electric push rod 25 is fixedly arranged at the center of the cavity opened inside the rotating shaft 21, and the two telescopic ends of the double-headed electric push rod 25 are respectively fixedly connected to a movable block 26, as shown in FIG. Figure 5 As shown, two opposite sides of the movable block 26 are provided with an inclined groove 27 respectively. The width of the inclined groove 27 is preferably matched with the diameter of the end of the connecting rod 22, so as to ensure that the end of the connecting rod 22 can slide in the inclined groove 27 without shaking or deviating. At least two groups of guide cylinders 29 inclined downward are symmetrically arranged on the side wall of the rotating shaft 21. The guide cylinders 29 are connected to the cavity inside the rotating shaft 21. Springs 24 are fixedly arranged in the guide cylinders 29. The springs 24 are all sleeved on one end of a connecting rod 22. The end of the connecting rod 22 sleeved with the spring 24 is always slidably fitted in the corresponding inclined groove 27.

[0029] When the spring 24 is in a natural state, the scraper 23 is away from the inner wall of the furnace drum 1, that is, the scraper 23 does not fit the inner bottom wall and side wall of the furnace drum 1, which is suitable for the case where there is material burning in the furnace drum 1. After the material is burned, the double-headed electric push rod 25 pushes the movable blocks 26 at both ends to move, and the movable blocks 26 push the connecting rod 22, so that the connecting rod 22 extends downward from the surface of the rotating shaft 21 along the guide cylinder 29, which can drive the scraper 23 to fit the inner wall of the furnace drum 1. Then, when the rotating shaft 21 rotates, the scraper 23 moves relative to the furnace drum 1, and the inner wall of the furnace drum 1 can be cleaned through the scraper 23, with better cleaning effect and stronger practicality.

[0030] For further information, see Figure 5 As shown, a vertical guide rod 211 is provided on the inner wall of the cavity inside the rotating shaft 21, and a vertical groove 261 adapted to the vertical guide rod 211 is provided on the outer circumference of the movable block 26.

[0032] When in use, air can enter the air outlet ring 33 through the air inlet ring 31 and be ejected through the air outlet hole 34, so as to transport oxygen into the furnace tube 1 to ensure more complete combustion of the material. When the rotating shaft 21 rotates, it can drive the air outlet ring 33 to rotate, and the rotation of the air outlet ring 33 can continuously adjust the air outlet position.

[0033] It can be understood that the structure of the scraper 23 is designed to be in an "L" shape, which can take into account the cleaning of the bottom wall and the side wall in the furnace drum 1, with better cleaning effect and stronger practicality.

[0034] The furnace drum 1, the feeding port 11, the smoke exhaust port 12, the discharging port 13, the double-headed electric push rod 25 and the motor 28 used in the present application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here.

[0035] Working principle: Before use, materials can be added into the furnace drum 1 through the feeding port 11, and the motor 28 can be started to drive the rotating shaft 21 to rotate. The rotation of the rotating shaft 21 can stir the materials in the furnace drum 1, so that the materials are turned up and scattered, so that they are fully burned, and the incineration effect can be guaranteed;

[0036] The upper end of the air inlet ring 31 is connected to the air source, and the air can enter the air outlet ring 33 through the air inlet ring 31 and be ejected through the air outlet hole 34, so that oxygen can be transported into the furnace tube 1 to ensure that the material is burned more fully. When the rotating shaft 21 rotates, it can drive the air outlet ring 33 to rotate, and the rotation of the air outlet ring 33 can continuously adjust the air outlet position;

[0037] When the rotating shaft 21 stirs the material, the scraper 23 is separated from the inner wall of the furnace drum 1, which can avoid the scraper 23 from rubbing against the inner wall of the furnace drum 1 for a long time and causing wear. When the inner wall of the furnace drum 1 needs to be cleaned, the double-headed electric push rod 25 is started, and the double-headed electric push rod 25 drives the upper and lower groups of movable blocks 26 to move upward, and the end of the connecting rod 22 contacts the inner wall of the inclined groove 27. As the movable block 26 moves upward, the connecting rod 22 can be pushed, so that the connecting rod 22 extends downward from the surface of the rotating shaft 21 along the guide cylinder 29, which can drive the scraper 23 to fit the inner wall of the furnace drum 1. When the rotating shaft 21 rotates, it drives the scraper 23 to move relative to the furnace drum 1, and the inner wall of the furnace drum 1 can be cleaned by the scraper 23. The scraper 23 has an "L" shape, which can take into account the cleaning of the inner bottom wall of the furnace drum 1, so that the cleaning effect is better and the practicability is stronger.
