Vehicle mobile soil washing and repairing device

Abstract

The invention discloses a vehicle mobile soil washing and repairing device. The device comprises a vehicle mobile platform, and a soil collection system, a power conveying system, a soil crushing and washing system, a treated soil output system and an agent filling system which are arranged on the vehicle mobile platform. The device is small in floor space, has mobility, and is capable of flexibly and conveniently treating a plurality of polluted areas according to the difference of the polluted areas, so that the secondary pollution to the local soil can be avoided; and furthermore, after the device is used, the soil is continuously mixed with a treating fluid, and the contact area between the treating fluid and the polluted soil can be enlarged under the action of a mixing structure in a wash trough, so that the treatment efficiency is improved.

Description

technical field [0001] The invention is a vehicle-mounted mobile soil washing and repairing equipment, with a power transmission system, a soil crushing and washing system and a medicament filling system as the core, and mainly uses physical and chemical methods to repair polluted soil, which belongs to the harmless soil waste The field of processing and resource utilization. Background technique [0002] With the aggravation of industrial and urban pollution and the increase in the types and quantities of agricultural chemicals, soil heavy metal pollution is becoming more and more serious, the degree of pollution is intensified, and the area is expanding year by year. Because heavy metal pollutants have poor mobility in soil, long residence time, cannot be degraded by microorganisms, and can eventually affect human health through water, plants and other media. Therefore, soil heavy metal pollution has become an important content of environmental science research. [0003]...

Problems solved by technology

In the prior art, a new type of soil washing machine (201120112397.5) is patented in China. The soil washing machine uses a spray system to mix the soil with a remediation solvent, and can treat the polluted soil so as to eliminate pollution. However, this utility model has the following disadvantages: (1) the utility model adopts the spraying method and cannot fully ensure that the soil and the remediation solvent are fully mixed, and the heavy metal waste produced cannot be guaranteed to be effectively separated from the soil; (2) the utility model The utility model adopts a trailer-type mobile platform, which needs to be additionally towed when moving, so it is inconvenient to implement

This utility model has the following deficiencies: (1) the whole system occupies a large area and exists in the form of digging and building foundation pits on the ground, which is likely to cause secondary pollution to the surrounding environment; (2) this utility model does not have a mobile function and cannot Realize the continued treatment of other polluted plots; (3) The utility model is manually controlled and cannot be automated

This utility model has the following deficiencies: (1) the system adopts a multi-layer up and down structure, and its reactor is at a high position in the system. This utility model does not have polluted soil filling equipment, so it is difficult to realize its effective treatment; (2) it is often to be treated The polluted site has a large area and a large amount. This utility model does not have a mobile platform, so it is very difficult to realize the portable treatment of heavy metal polluted soil.

This invention patent has the following deficiencies: (1) The temporary civil construction sewage treatment tank for leaching cannot be called a mobile soil leaching equipment device, and its relatively simple civil construction foundation pit cannot be moved and re-used. It is easy to produce secondary pollution; (2) The filling mechanism of the equipment to be treated and how the wet-screened soil is transferred to the next process are not mentioned
