Contaminated soil grinding treatment device

Abstract

The invention relates to the technical field of soil grinding equipment, and discloses a contaminated soil grinding treatment device. The contaminated soil grinding treatment device comprises a grinding chamber, wherein grinding rollers are rotatably connected with the interior of the grinding chamber, driving wheels are fixedly connected with rotating shafts of the grinding rollers, first belts are movably connected with the outer side walls of the driving wheels, and transmission wheels are movably connected with the outer side walls of the first belts. Convex surfaces of cams are made to be in continuous contact with movable wheels on connection rods, the movable wheels are driven by the cams to move inwards, thus the connection rods on the movable wheels continuously turn over to and fro under the action of reset springs, then sliding rods on transverse rods are driven by the connection rods to move to and fro, thus soil is continuously squeezed and shaken by a corresponding movable board on a corresponding supporting board at one end of each sliding rod, the soil is made to be in contact with grinding blades on the grinding rollers more frequently, thus the efficiency of grinding the soil is improved, and meanwhile, the soil is continuously driven by the movable boards to shake, so that the phenomenon of dead angles during soil grinding is prevented.

Description

technical field [0001] The invention relates to the technical field of soil crushing equipment, in particular to a contaminated soil crushing treatment device. Background technique [0002] At present, with the development of industry, more and more pollution sources enter the soil. When the self-purification ability of the soil is insufficient, the soil needs to be repaired. Soil restoration is a technical measure to restore the normal function of the polluted soil. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Among them, soil crushing is an important environment for soil remediation. Soil crushing can increase the contact area between soil and chemicals, and improve the efficiency of soil restoration. [0003] In the prior art, in the process of crushing the soil, the crushi...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a polluted soil crushing treatment device, which has the advantages of automatically squeezing and shaking the soil, avoiding crushing dead angles and improving crushing efficiency, and solves the problem of crushing the soil by crushing rollers. In the process, in order to prevent the soil from clogging the outlet, a gap is usually reserved. However, the reserved gap will cause a dead angle between the soil and the crushing roller. The existing device cannot shake and squeeze the soil, resulting in a dead angle and a crushing of the soil. The problem of low crushing efficiency
