Description

Technical Field

[0001] This utility model belongs to the technical field of soil environmental monitoring, specifically relating to a rapid soil drying device for detecting heavy metals in soil. Background Technology

[0002] When detecting heavy metals in soil, soil samples need to be dried to remove moisture, facilitating subsequent analysis and detection. Traditional natural air drying methods are slow and highly susceptible to weather conditions, failing to meet the demands for rapid detection. Therefore, developing rapid soil drying devices is of great significance for improving soil testing efficiency.

[0003] Early soil drying relied mainly on natural air drying and simple heating equipment such as ovens. With technological advancements, more efficient and precise rapid soil drying devices have been developed to meet the soil testing needs in various scenarios.

[0004] Rapid soil drying devices typically employ technologies such as heating and ventilation to accelerate the evaporation of moisture from the soil, thereby achieving the goal of rapid drying.

[0005] However, the internal temperature of the rapid soil drying device used for heavy metal detection in soil will drop when it discharges the material after heating and air drying. It usually needs to be reheated during the next air drying, which can easily lead to waste of heat source and is not conducive to improving resource utilization.

[0006] This invention addresses the aforementioned problems by providing a rapid soil drying device for detecting heavy metals in soil, which can retain some temperature for preheating. Utility Model Content

[0007] The purpose of this invention is to provide a rapid soil drying device for detecting heavy metals in soil, in order to solve the problem mentioned in the background art that the internal temperature of the rapid soil drying device for detecting heavy metals in soil decreases when it is discharged after heating and air drying, and it usually needs to be reheated during the next air drying, which easily leads to waste of heat source and is not conducive to improving resource utilization.

The driving connecting cylinder pulls and pulls the piston to evacuate air from the inside of the soil rapid drying device through the air inlet. When the device is full, the piston pulls and squeezes the compression connecting block, allowing the air inside the telescopic connecting body one to enter the telescopic connecting body two and drive the lifting and closing door to close the air inlet.
