Closed environment-friendly type soil remediation equipment

Abstract

The invention discloses closed environment-friendly type soil remediation equipment. The closed environment-friendly type soil remediation equipment comprises an equipment body, a feeding port, a drugliquid mixing cavity and a mounting seat, the upper part of the left side of the equipment body is provided with the feeding port, the lower part of the feeding port is connected with a smashing cavity, a drug liquid spraying cavity is formed in the lower part of the smashing cavity, a worm located on the right side of the feeding port is fixedly mounted in the middle of the upper surface of thesmashing cavity, a worm gear is arranged on the right side of the worm, and the mounting seat is arranged in the smashing cavity; the right side of the smashing cavity is provided with the drug liquidmixing cavity, the left side of the drug liquid mixing cavity is welded to the middle of the right side wall of the smashing cavity, and the drug liquid spraying cavity is symmetrically and obliquelyprovided with the drug liquid temporary storage cavities; and a second rotary shaft is arranged in each drug liquid spraying cavity. The closed environment-friendly type soil remediation equipment can achieve repeated smashing and crushing treatment on the soil, the phenomenon that the soil cannot sufficiently absorb the drug liquid because the soil is agglomerated is avoided, and remediation ofsoil is effectively achieved.

Description

technical field [0001] The invention relates to the technical field of soil restoration equipment, in particular to a closed environment-friendly soil restoration equipment. Background technique [0002] As we all know, soil pollution, as a problem that restricts the sustainable development of human society, is attracting more and more attention from all over the world. The main causes of soil pollution are excessive use of chemical fertilizers and chemical pesticides, improper disposal of various sewage, sludge and organic waste, accidental discharge of harmful substances, and long-term accumulation of various pollutants in the soil. Soil pollution causes secondary pollution to groundwater and surface water, and enters the human body through the food chain through drinking water or soil-plant systems, endangering human health. Soil remediation is a technical measure to restore polluted soil to normal functions. It refers to the use of physical, chemical and biological meth...

Problems solved by technology

However, in the process of soil remediation, the degree of soil fragmentation often has a greater impact on the remediation effect of the soil. The smaller the particles of the soil after crushing, the more fully it reacts with the reactants, and the better the remediation effect; Existing soil remediation generally sprays chemicals directly into the soil to improve soil properties. This repair method is simple, but the repair effect is not good. The liquid is sprayed on the soil surface and cannot fully repair the soil, resulting in a waste of resources. At the same time, the atomized agent is easy to spread with the air, causing environmental pollution, so it is necessary to design a closed environment-friendly soil remediation equipment
