A detection device for soil pollution remediation with multi-stage screening function

Abstract

The invention discloses a detection device for soil pollution remediation with multi-stage screening function, and relates to the technical field of soil detection. The upper and lower sides are fixedly connected with blocking plates. Through the mutual cooperation between the provided thread, the inner thread ring, the T-shaped slider, the linkage rod and the crushing blade, the inner thread ring can be moved downward through the threaded connection with the thread by rotating the inner thread ring, and at the same time the four The T-shaped slider slides in the T-shaped ring groove, and the four T-shaped sliders then drive the linkage rod to move down, and the four linkage rods then drive the four hinged arc plates to turn to the outside, so that the four arc-shaped The plate is in an unclosed state, which is convenient for grasping and collecting the soil, and the cylinder, the square cylinder and the upper part of the connecting plate are connected to each other, which realizes the integration of soil crushing and screening, and improves the work efficiency.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a detection device for soil pollution restoration with a multi-stage screening function. Background technique [0002] In a broad sense, soil bioremediation technology refers to all soil pollution control technologies that use organisms as the main body, including the use of plants, animals and microorganisms to absorb, degrade, and transform pollutants in the soil, so that the concentration of pollutants can be reduced to an acceptable level. Or convert toxic and harmful pollutants into non-toxic and harmless substances, and also include fixing or stabilizing pollutants to reduce their spread to the surrounding environment. The narrow soil bioremediation technology refers to the use of yeast, fungi, bacteria It is the process of removing pollutants in the soil by the action of microorganisms, or making the pollutants harmless. As the soil pollution becomes more and more s...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a detection device for soil pollution remediation with a multi-stage screening function, which solves the problem of using tools such as shovels to dig out the soil to be detected, and then bring it back to the laboratory for crushing and remediation. The solution is mixed, and doing so often takes a lot of time, and the crushing effect on hard soil is often not good, which is easy to cause deviations in the test results, and the crushed soil needs to be sieved by particle diameter when necessary , which is convenient for differential detection, but the existing screening method only relies on the filter screen for screening, the effect of screening is limited, and there are limitations
