[0002] In existing technologies, physical, chemical, or biological methods are commonly used to remediate contaminated soil during the soil remediation process.

[0003] In existing technologies, during the application of soil remediation: Traditional equipment often uses external heating or static heating methods, which leads to uneven heating of the soil and affects the efficiency of pollutant volatilization or degradation. Often there is no structure for simultaneous steam input and output, and the other treatment devices have a single steam input method, which can easily limit the effectiveness of soil remediation. Lacking intelligent control and relying on manual operation, the remediation process is difficult to precisely regulate; therefore, we have made improvements and proposed an ecological remediation and treatment device for contaminated soil.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of this utility model can be combined with each other.

[0017] like Figures 1-6 As shown, this embodiment proposes a soil ecological remediation and treatment device, including a soil mixing drum 1 and a mixing rod 2. The surface of the mixing rod 2 is embedded with a heating wire 3. The outer end of the heating wire 3 is connected to a control panel 4 and a thermal sensor. The top of the soil mixing drum 1 is provided with multiple sets of steam ports 5. Each set of steam ports 5 is provided with a movable cylinder 6 and a linkage spring 7. The lower end of the soil mixing drum 1 is provided with a discharge port 8. The inner end of the discharge port 8 is provided with a blocking block 9. Two sets of telescopic rods 10 are provided between the blocking block 9 and the discharge port 8. The lower end of the discharge port 8 is provided with a feeding port 11.

[0018] Each steam inlet 5 extends through the top of the soil mixing drum 1. The steam inlet 5 is slidably connected to the movable drum 6, and the movable drum 6 and the steam inlet 5 are movably connected by a linkage spring 7.

[0019] Multiple air outlets are provided horizontally through the inner end of the movable cylinder 6, and the material outlet 8 is located at the lower end of the soil mixing cylinder 1.

[0020] The discharge port 8 and the blocking block 9 are slidably connected, and the blocking block 9 and the discharge port 8 are movably connected by the telescopic rod 10.

[0021] The telescopic rod 10 is connected to the control panel 4 via a signal connection, and the feed port 11 is connected to the discharge port 8 via a through connection.

[0022] The control panel 4 can be a panel with multiple signal inputs and outputs, PID temperature control function, and support for human-machine interaction, facilitating the setting of heating parameters and material discharge control, such as a Siemens S7-1200 PLC + HMI touch screen; the heating wiring 3 can be a high-temperature resistant, flexible heating wire harness that can be embedded inside the stirring rod 2, providing uniform heating and with a maximum temperature resistance of over 200°C, such as the SRX series silicone rubber heating belt; the thermal sensor can be a high-precision, stable temperature sensor suitable for high-temperature and high-humidity soil environments, capable of working with the PLC to achieve real-time temperature feedback and control, such as the PT100 platinum resistance temperature sensor. When this application is used: After the equipment is started, the operator sets the heating temperature through the control panel 4; the heating wires 3 built into the stirring rod 2 start working, and the temperature is monitored in real time with the heat sensor to ensure that the soil is heated evenly; steam enters or exits the soil mixing drum 1 through the steam port 5. The movable drum 6 can be adjusted to be connected to the external steam inlet or to the steam exhaust pipe as needed under the action of the linkage spring 7, which can enhance the contact area between the steam and the soil, or discharge excess steam and improve the repair efficiency; after the repair is completed, the control panel 4 controls the extension rod 10 to extend, which drives the blockage block 9 to open the discharge port 8, and the soil is discharged through the discharge port 11 under the stirring of the stirring rod 2. When treating highly viscous contaminated soil, the movable cylinder 6 moves outward under the action of steam pressure, overcoming the resistance of the linkage spring 7, so that the vent is pushed upward to discharge excess steam and prevent steam from accumulating on the surface. The stirring rod 2 continuously stirs and heats, promoting the volatilization and decomposition of pollutants. During discharge, the telescopic rod 10 controls the opening of the blockage block 9 in stages to achieve controllable discharge and avoid blockage and dust.
