DETAILED DESCRIPTION

There are two locking members 6, and the drawers A power assist member is installed on the front side of the drawer 5, an exhaust port 7 is installed on the left side of the mounting frame 1, a heating pipe 8 is connected to the inside of the mounting frame 1, a soil crushing mechanism 9 is provided on the mounting frame 1, and the soil crushing mechanism 9 includes a connecting plate 95, a connecting plate 95 is connected to the inside of the mounting frame 1, a soil crushing plate 91 is slidably connected to the connecting plate 95, two handles 92 are connected to the soil crushing plate 91, and guide members 93 are connected to the four corners of the connecting plate 95, and the guide members 93 are all slidably connected to the soil crushing plate 91, and a first spring 94 is connected between the soil crushing plate 91 and the guide member 93.

[0020] like Figures 1-4 As shown, it also includes a shock absorbing mechanism 10, which includes a damper 101. The lower sides of the left and right parts of the installation frame 1 are connected to the front and rear symmetrical dampers 101, the inside of the damper 101 is connected to the second spring 102, and the lower part of the damper 101 is connected to the installation base 103.

[0021] It should be noted that the thermal desorption technology of heavy metal pollution in soil is an effective physical and chemical remediation method, which uses heating to cause volatile organic pollutants in the soil to evaporate, thereby repairing and improving the soil. First, turn the cover door 3 to the right so that the clamping parts on the cover door 3 are out of the clamping state with the feed hopper 2, and then pour the soil raw materials into the feed hopper 2. The soil raw materials gather on the right side of the leak plate 11, and then turn on the vibration component 4. The vibration component 4 drives the soil raw materials to disperse. At the same time, the leak plate 11 is an inclined structure with the right higher and the left lower, which is more convenient for the soil raw materials to move to the left. The heating tube 8 performs pyrolysis treatment on the dispersed soil, and the flying dust and the gas generated after pyrolysis can be discharged through the exhaust port 7 to avoid harm to the operator. When encountering large-volume soil blocks, put the soil blocks into the feed hopper 2, and the soil blocks move to the leak plate 11. The operator The operator can use the handle 92 to squeeze the soil crushing plate 91 downward, so that the soil crushing plate 91 slides downward on the guide member 93, the first spring 94 is compressed, the soil crushing plate 91 contacts the soil block and crushes it, and the heating tube 8 pyrolysis treatment is performed on the crushed soil block. This method can make the heavy metal substances in the soil more fully pyrolyzed, improve the pyrolysis effect, and at the same time improve the pyrolysis efficiency of heavy metal pollution in the soil. After the soil is pyrolyzed, the operator uses the power assist member on the drawer 5 to pull the drawer 5 outward to discharge the soil. During the pyrolysis process, the vibration component 4 drives the installation frame 1 to vibrate. In order to avoid hard contact between the base of the installation frame 1 and the ground due to vibration, a damper 101 and a second spring 102 are provided to reduce the direct impact between the base of the installation frame 1 and the ground, disperse the vibration force of the installation frame 1, thereby protecting the installation frame 1.
