The first embodiment is as follows: as shown in fig. 1 and 2, which are only one embodiment of the present invention, a dual-circulation soil remediation device includes a stirring portion 1, a chemical adding portion 2, and a conveyor belt 3 disposed below the stirring portion 1 and the chemical adding portion 2, wherein a soil inlet pipe 11 is disposed above the stirring portion 1, a first discharge pipe 12 for facilitating soil in the stirring portion 1 to fall onto the conveyor belt 3 is disposed below the stirring portion 1, a first circulation port 31 connected to an upper end of the stirring portion 1 through a first circulation pipe 311 is disposed at a tail end of the conveyor belt 3 in a running direction, a second circulation port 32 connected to an upper end of the chemical adding portion 2 through a second circulation pipe 321 is disposed between the first discharge pipe 12 and the first circulation port 31, a second discharge pipe 22 for facilitating soil in the chemical adding portion 2 to fall onto the conveyor belt 3 is disposed at a lower end of the chemical adding portion 2, one end of the second discharge pipe 22, which is far away from the chemical adding portion 2, is located at a side of the first discharge pipe 12, which is close to the front end of the conveyor belt 3 in the running direction, and a soil discharge port 33 is disposed between the second discharge pipe 22 and the first discharge pipe 12.
In this embodiment, the stirring part 1 includes a rotating bin 13 and a fixed bin 14 disposed at a lower side of the rotating bin 13, and the first discharging pipe 12 is disposed at a lower side of a center of the fixed bin 14
Further, the first circulation pipe 311 is provided with a first negative pressure machine 312 for sucking up the soil transferred to the tail end of the conveyor belt 3 and spraying it under pressure on the upper side of the rotary bin 13.
Similarly, the second circulation pipe 321 is provided with a second negative pressure machine 322, and the soil discharge pipe 331 is provided with a third negative pressure machine 332.
In the present invention, remediation is performed during soil transport with two cycles:
a first circulation, which takes the stirring part 1 as a core, the soil to be repaired falls into the stirring part 1 from the soil inlet pipe 11 for stirring, the stirred soil falls onto the conveyor belt 3, and when the soil passes through the second circulation port 32, soil particles with the particle mass less than a first preset value are sucked up by the negative pressure of the second negative pressure machine 322 and enter the second circulation pipe 321; the soil with the particle mass larger than the first predetermined value moves to the end of the conveyor belt 3, is sucked into the first circulation pipe 311 under the negative pressure of the first negative pressure machine 312, and falls into the stirring part 1 again for stirring;
a second circulation, taking the dosing part 2 as a core, allowing the small-particle soil entering the second circulation pipe 321 to enter the dosing part 2 to chemically react with the liquid medicine added in the dosing part 2, neutralizing the toxic substances, allowing the reacted soil to fall onto the conveyor belt 3 from the second discharge pipe 22 at the bottom of the dosing part 2 and be located in front of the first discharge pipe 12, and allowing the soil to pass below the soil discharge port 33 under the transmission of the conveyor belt 3, wherein if the soil particles to be detoxified are small enough, the soil particles with the particle mass smaller than a second predetermined value enter the soil discharge pipe 331 under the negative pressure of the third negative pressure machine 332 to be discharged; on the contrary, the liquid is moved to the end of the conveyor 3, sucked into the first circulation pipe 311 under the negative pressure of the first negative pressure machine 312, and dropped into the stirring section 1 again to be stirred and subjected to chemical addition treatment.
In the above, the first negative pressure machine 312 controls the first circulation pipe 311 to be indifferently adsorbing, and all the soil reaching the tail end of the conveyor belt 3 enters the first circulation pipe 311; however, the magnitude of the pressurization of the first negative pressure machine 312 affects the initial speed of the soil entering the stirring section 1, thereby controlling the uniformity of the soil stirring.
In addition, the second circulation pipe 321 and the soil discharge port 33 are selectively adsorbed, that is, the soil particles adsorbed at the second circulation port 32 and the soil discharge port 33 are adjustable, that is, the first predetermined value and the second predetermined value are controllable.
In short, the power of the first negative pressure machine 312, the second negative pressure machine 322 and the third negative pressure machine 332 only needs to be controlled to achieve different degrees of soil remediation rates.
The double-circulation soil remediation device is simple in structure, high in soil remediation degree by performing multiple circulation treatment on soil, high in intelligence degree and good in automatic operation, and harmful substance residues in the soil are reduced as much as possible.
