Stone sieving machine for soil restoration as well as sieving method of stone sieving machine

Abstract

The invention discloses a stone sieving machine for soil restoration as well as a sieving method of the stone sieving machine. The stone sieving machine for soil restoration comprises a crushing device, a sieving device and a transfer belt, wherein a discharging opening of the crushing device is rotatably connected with a feeding opening of the sieving device; the head end and the tail end of thetransfer belt are connected with a discharging opening of the sieving device and a feeding opening of the crushing device respectively; the crushing device, the sieving device and the transfer belt form a closed chain; the sieving device comprises an outer roller, a first inner container and at least one layer of second inner container; the first inner container and the second inner container comprise an inner container wall and an outer container wall; the inner container wall and the outer container wall can rotate relative to each other. According to the stone sieving machine as well as thesieving method thereof, the sieving quality can be improved through sieving for many times.

Description

technical field [0001] The invention relates to the field of soil restoration, in particular to a stone screening machine for soil restoration and a screening method thereof. Background technique [0002] In recent years, with my country's continuous emphasis on the environmental protection industry, more and more scientific and technical personnel have begun to invest in the research and manufacture of environmental protection equipment, especially for soil remediation technology. This is because the situation of soil pollution is severe and the speed of national legislation has been significantly accelerated. In addition to adding soil remediation to the new "Environmental Protection Law", the Ministry of Environmental Protection also announced the new "Soil Environmental Quality Standards (Draft for Comment)", "Soil Pollution Prevention and Control Action Plan" (referred to as "Soil Ten Articles") The formulation and implementation of is also put on the agenda. The larg...

Problems solved by technology

Existing soil sieving machines are mostly planar, and the soil is separated layer by layer through the vibrating screen, but the energy consumption of the vibrating screen type soil separator is relatively large, and fatigue damage occurs

Moreover, when the diameter of the particles in the soil changes greatly, it can only be separated by adding the number of sieves, which requires a larger sieving machine, and the energy consumed will increase accordingly, and the cost will rise sharply. Satisfy the existing soil remediation market
