Description

Soil remediation sieving mechanism

Technical Field

The invention relates to the technical field of soil remediation, in particular to a soil remediation screening device.

Background

Soil remediation refers to the physical, chemical and biological processes used to transfer, absorb, degrade and transform pollutants in soil to reduce their concentration to acceptable levels, or to transform toxic and harmful pollutants into harmless materials. Fundamentally, the technical principle of contaminated soil remediation can include (1) changing the existing form of the contaminants in the soil or the combination mode of the contaminants and the soil, and reducing the mobility and bioavailability of the contaminants in the environment; (2) the concentration of harmful substances in the soil is reduced, the soil is originally a natural accommodation place and a purification treatment place of various wastes, the soil accepts pollutants and does not indicate that the soil is polluted, and the soil is only indicated to be polluted if the various pollutants accommodated in the soil are excessive and influence and exceed the self-cleaning capacity of the soil, so that the soil is harmfully influenced hygienically and epidemiologically. Causes of soil pollution, such as industrial sludge, garbage agriculture, sewage irrigation, pollutant sedimentation in the atmosphere, and the use of heavy metal-containing mineral fertilizers and pesticides in large quantities.

Chinese patent publication No. CN 208662112U discloses a soil remediation sieving mechanism, this soil remediation sieving mechanism, through the motor, initiative runner, the connecting band, the rotary drum, mutually supporting of a sieve section of thick bamboo and loose bearing etc. is used, thereby make this sieve section of thick bamboo rotate the screening, again because the grog device stretches into the inside of a transition section of thick bamboo, and a transition section of thick bamboo links to each other with a sieve section of thick bamboo, so the raw materials that get into the device carry out the screening for the first time, and the waste residue after the screening goes out from the second slag notch, and remaining fall into on the vibration sieve board of below, carry out the screening once more, and at this moment the waste residue goes out from first slag notch again, and soil remediation case at this moment passes through sprinkler blowout medicament, thereby the effect of the soil remediation screening that makes the device is better. But the device can not dry soil, and moist soil agglomerates easily, not only influences the efficiency of screening, still can cause a large amount of soil to get rid of along with debris, causes the waste.
