description The invention discloses a multi-stage extraction detection device for total petroleum hydrocarbon in soil, which comprises a detection table, a fixed seat is arranged above the detection table, a first extraction device, a second extraction device and a separation device are arranged in the fixed seat, the second extraction device is arranged between the first extraction device and the separation device, and the separation device is arranged between the first extraction device and the separation device. Compared with an existing extraction detection device, the temperature adjusting mechanism is additionally arranged, the liquid level and viscosity changes of extraction liquid in the first extraction tank can be judged in real time through the temperature adjusting mechanism and the magnetic plate and the coil arranged at the lower end of the stirring rod, and then the temperature increasing amplitude of the heating plate is automatically adjusted; in addition, an isolator is arranged in the separation bottle
