Description

Soil screening device for soil remediation Technical Field The utility model relates to the technical field of soil remediation, in particular to a soil screening device for soil remediation. Background In soil remediation, soil screening is an important technology, and in order to ensure thorough mixing of contaminated soil and remediation stabilizer and protection of soil mixing equipment, the contaminated soil needs to be subjected to post-crushing screening treatment, and the contaminated soil and impurities are classified so as to improve the soil remediation effect. The utility model relates to the technical field of soil remediation, in particular to a soil screening device for soil remediation, which comprises a soil screening frame which is obliquely arranged, wherein a feed hopper is arranged at the feed end of the soil screening frame, vertical frames are arranged at four top corners of the bottom of the soil screening frame, and a vibrating motor is arranged on the outer wall of one side of the soil screening frame; the bottom surface of the soil screening frame is provided with a replaceable screen. According to the utility model, the installation side seat of the replaceable screen is connected to the side wall of the soil screening frame through the plurality of groups of locking bolts, so that the device is more flexible and convenient, the screen can be replaced at any time, the pore size can be adjusted according to the needs, the device is suitable for repairing different types of soil, the soil and impurities after screening can be respectively collected by the arrangement of the soil collecting hopper and the impurity collecting hopper, the subsequent treatment is convenient, and the vibration motor arranged on the outer wall of one side of the soil screening frame can generate vibration, so that the material is subjected to certain vibration on the screen, and the soil screening is facilitated. The screening device in the above patent still has certain defect, because current soil screening device adopts bed formula screening net screening mostly, and bed formula screening net in the in-service use's in-process, because often moisture, clay or humus in the soil, easily lead to the jam of bed formula screen cloth sieve mesh, the in-process that bed formula screen cloth was screened soil still can produce a large amount of raise dust and fly away in the air simultaneously, causes the pollution of environment to and harm workman's health.
