[0022] Please refer to Figures 1-4 As shown in the figure, a heavy metal soil thermal desorption and remediation device includes a bottom plate 1. Above the bottom plate 1, a heating box 2 is fixedly connected. Inside the heating box 2, a drum 5 is rotatably installed. On the surface of the drum 5, a snap ring 4 is fixedly connected. Near one side of the surface of the drum 5, a gear ring 7 is fixedly connected. On the surface of the gear ring 7, a gear 8 is meshed. The output end of a motor 9 is fixedly connected to the outside of the gear 8. Near the position of the drum 5 on the surface of the bottom plate 1, a feed hopper 10 is fixedly connected. At the rear of the heating box 2 and below the drum 5, a discharge plate 11 is fixedly connected. On the surface of the bottom plate 1, a water tank 17 is fixedly connected. One end of a water pump 16 is fixedly connected to the surface of the water tank 17. The other end of the water pump 16 is fixedly connected to the bottom end of a connecting pipe 15;

[0023] Furthermore, a partition plate 6 is fixedly connected to the inner wall of the drum 5, and the partition plate 6 is arranged in a spiral pattern on the inner wall of the drum 5;

[0024] During operation, due to the structural design that a partition plate 6 is fixedly connected to the inner wall of the drum 5 and the partition plate 6 is arranged in a spiral pattern on the inner wall of the drum 5, it is convenient for the soil to move towards the discharge plate 11 while being processed and baked, facilitating the continuous operation of the device.

[0025] Furthermore, support pulleys 3 are fixedly connected to the inner wall of the bottom plate 1, and the surface of the support pulleys 3 is slidably connected to the inner wall of the snap ring 4;

[0026] During operation, due to the structural design that support pulleys 3 are fixedly connected to the inner wall of the bottom plate 1 and the surface of the support pulleys 3 is slidably connected to the inner wall of the snap ring 4, the drum 5 is limited, improving the stability of the drum 5 during rotation.

[0027] Furthermore, a support plate 12 is fixedly connected to the surface of the bottom plate 1. Inside the support plate 12, a through pipe 13 is rotatably connected. On the surface of the through pipe 13, a support frame 14 is rotatably connected, and the support frame 14 is fixedly connected to the inner wall of the drum 5;

[0028] During operation, due to the structural design that a support frame 14 is rotatably connected to the surface of the through pipe 13 and the support frame 14 is fixedly connected to the inner wall of the drum 5, the through pipe 13 is located near the center inside the drum 5.

[0029] Furthermore, a baffle 51 is fixedly connected to one side inside the drum 5 near the feed hopper 10, and the bottom of the motor 9 is connected to the bottom plate 1;

[0030] During operation, due to the structural design of the baffle 51 fixedly connected inside the drum 5, the possibility of soil spilling out when feeding materials into the drum 5 is reduced.

[0031] Furthermore, a number of nozzles 131 are equidistantly distributed on the surface of the through pipe 13, and the nozzles 131 are arranged directly below the through pipe 13.

[0032] During operation, due to the structural design of a number of nozzles 131 being equidistantly distributed on the surface of the through pipe 13, it is convenient to evenly wash and clean the inner wall of the device. Due to the structural design of the nozzles 131 being arranged directly below the through pipe 13, the impact of soil on the nozzles 131 is reduced, and the service life of the device is prolonged.

[0033] Working principle: Start the motor 9 through an external power supply. The motor 9 drives the gear 8 and the gear ring 7 to make the drum 5 rotate. The snap ring 4 on the surface of the drum 5 is slidably connected with the support pulley 3 to position the drum 5. Add the soil raw materials to be processed through the feed hopper 10. At the same time, start the heating box 2 through an external power supply. The baffle 51 reduces the possibility of raw material leakage. The partition plates 6 arranged in a spiral shape inside the drum 5 facilitate the movement of the soil towards the discharge plate 11 while being processed and baked, facilitating the continuous operation of the device. The processed raw materials are discharged from the discharge plate 11.

[0034] After the device has been working for a long time, dry soil may accumulate inside the drum 5, affecting the thermal desorption efficiency of the device. At this time, start the water pump 16 through an external power supply. The water pump 16 extracts the cleaning solution from the water tank 17. Since the top end of the connecting pipe 15 is fixedly connected to the outside of the connecting pipe 15, the connecting pipe 15 sends the cleaning solution into the through pipe 13 and finally sprays out from the nozzles 131. The drum 5 is in a rotating state, facilitating the cleaning of the inside of the drum 5.
