Heavy metal contaminated soil washing equipment

Abstract

The invention discloses heavy metal contaminated soil washing equipment. Two stages of crushing devices are arranged; collected soil is preliminarily crushed through the first-stage crushing device; the second-stage crushing device is used for finally crushing the soil; through the two-stage crushing devices, the soil is thoroughly crushed and thus the soil and the detergent can be conveniently mixed, so that the washing efficiency is greatly improved; a nozzle arranged on a washing and mixing mechanism atomizes the detergent, so that resources are saved, the resource consumption is reduced, and the purification washing cost is lowered; the contact area of the detergent and the crushed soil is increased, so that, the washing efficiency is improved; a batch loading mechanism guides soil into the equipment in batches, so that the equipment is prevented from being blocked and damaged; meanwhile, soil is easier to smash and purify, the purification time is shortened, and the soil washing efficiency is improved; water stains and chemical agents left by washing in the soil are separated from the soil when the soil is guided out of the equipment through a solid-liquid separation conveyingdevice, so that secondary pollution of the soil is avoided.

Description

technical field [0001] The invention belongs to the technical field of soil purification equipment; in particular, it relates to heavy metal polluted soil washing equipment. Background technique [0002] Soil is an important resource for human survival. At present, the soil environment problem in the world is serious. Due to the advancement of science and technology and the development of industry, the soil problem is becoming more and more serious, especially the acidification of soil, soil acidification and other trace metal elements in the soil The content far exceeds the normal value, and then soil heavy metallization occurs. At the same time, the industrial products used by human beings cause the soil to be seriously polluted by organic matter. Due to the long-term development of industry and human dependence on industrial products, trace metal elements in the soil and The high content of organic matter due to excessive deposition has made the problem of soil pollution ...

Problems solved by technology

[0002] Soil is an important resource for human survival. At present, the soil environment problem in the world is serious. Due to the advancement of science and technology and the development of industry, the soil problem is becoming more and more serious, especially the acidification of soil, soil acidification and other trace metal elements in the soil The content far exceeds the normal value, and then soil heavy metallization occurs. At the same time, the industrial products used by human beings cause the soil to be seriously polluted by organic matter. Due to the long-term development of industry and human dependence on industrial products, trace metal elements in the soil and The high content of organic matter due to excessive deposition has made the problem of soil pollution increasingly prominent. Of course, for heavy metal pollution in the soil, people can repair it through soil leaching technology, specifically by cleaning the polluted soil with water or chemical solutions An operation method to separate pollutants from the soil, but there is no effective low-cost heavy metal-contaminated soil washing equipment, so a kind of washing effect, low-cost, and easy-to-operate heavy metal-contaminated soil washing equipment appears imminent
