Description

Technical Field

[0001] The invention relates to the technical field of soil remediation experiments, and in particular to an experimental device for remediating contaminated soil. Background Art

[0002] Contaminated soil remediation refers to the technical measures that use physical, chemical, biological, and ecological principles and artificial control measures to reduce the concentration (activity) of soil pollutants, achieve harmlessness and stabilization of pollutants, and achieve the desired detoxification effect. By repairing contaminated soil, pollutants can be prevented from entering the human body through the food chain, thereby reducing harm to human health. Soil is an important part of the ecosystem. Repairing contaminated soil can restore the ecological function of the land, maintain biodiversity, and promote ecological balance. Soil remediation not only focuses on current environmental problems, but also focuses on future sustainable development. By repairing damaged land, it provides support for future ecological environmental protection and economic development. By improving soil and reducing pollution, the soil environment can be effectively improved. Improve environmental quality, fruit quality, and increase production. Excessive use of chemical fertilizers, pesticides, agricultural films, etc. will lead to soil pollution, affecting soil fertility and biological activity. Soil remediation can help improve these problems and restore the health of the soil. Before conducting contaminated soil remediation, it is usually necessary to use a test device to conduct simulation tests to test the contaminated soil remediation effect. However, the common test devices for contaminated soil remediation on the market have poor soil layer simulation effects during the test due to the structure of the test device itself. The soil permeability cannot be simulated realistically and flexibly. It is not convenient and cumbersome to turn the soil inside the test device, and the turning of the soil is not uniform. When adding soil remediation agents, it is usually added manually, which is not uniform, affecting the remediation effect and resulting in inaccurate data. Summary of the invention

When soil remediation agent needs to be added, the soil remediation agent can be added to the interior of a storage tank in advance, and then the force-bearing head component can be controlled to approach the storage structure through a driving motor.

If it is necessary to add soil remediation agent, first add the soil remediation agent into the storage tank 303, and then control the driving motor to operate again, so that the force-bearing head component 202 is close to the storage structure 3, control the connecting rod 203 to rise, and connect the connecting rod 203 and the fixed head 301 together for use, and control the driving motor to operate again to drive the storage structure 3 to move together. While moving, the force-bearing rod 308 is guided to move inside the control groove 102. Since the control groove 102 is a curved wavy structure, it controls the sliding rod 305, the linkage rod structure 306 and the blocking rod 307 to move back and forth together, and controls the cyclic opening and closing of the discharge hole, so that the soil remediation agent can be added conveniently and evenly, thereby improving the test effect and the uniformity of adding the soil remediation agent.
