Description

Technical Field

[0001] The utility model relates to the technical field of soil pollution prevention and control, in particular to soil pollution prevention and control equipment. Background Art

[0002] For example, the patent number published on the China Patent Network is: 201711379951.4, and the patent name is: A high-efficiency soil pollution treatment device. The structure of the present invention is ingenious. The fan conveys airflow into the drum through the air duct. At the same time, the electric heating wire in the drum is energized to heat the air to form hot air. The hot air is sprayed to the soil through the vents on the side wall of the drum. The airflow loosens the soil so that the soil and the liquid medicine are fully in contact. In addition, the hot air increases the reaction temperature, which greatly improves the reaction efficiency between the soil and the liquid medicine. The excess liquid medicine is filtered through the filter and enters the liquid storage tank for recycling. The stirring motor drives the horizontal axis in the liquid storage tank to rotate. The stirring blades on the horizontal axis stir the liquid medicine in the liquid storage tank to prevent the liquid medicine from failing. After the reaction is completed, the drum rotates, and the stirring blades on the outside of the drum stir the soil to improve the reaction efficiency. After sufficient reaction, the soil enters the bottom of the right end of the shell and enters the discharge barrel. The discharge motor drives the spiral discharge shaft to push the soil out of the discharge port and into the conveyor belt.

[0003] However, the structure of the existing soil pollution treatment device is relatively simple, and the airflow can only be directly injected into the soil through a pipe. After the airflow is injected, it will float directly due to gravity, which affects the contact area between the airflow and the soil.

[0004] Therefore, it is necessary to redesign and transform soil pollution prevention and control equipment. Utility Model Content
