A polluted soil pulverization treatment device

Abstract

The present invention relates to the technical field of soil crushing equipment, and discloses a polluted soil crushing treatment device, which includes a crushing chamber, and a crushing roller is rotatably connected to the interior of the crushing chamber, and a driving wheel is fixedly connected to the rotating shaft of the crushing roller. The outer wall of the driving wheel is movably connected with a belt one, and the outer wall of the belt one is movably connected with a transmission wheel. The convex surface of the cam is constantly in contact with the movable wheel on the connecting rod, and drives the movable wheel to move inward, so that the connecting rod on the movable wheel is continuously turned back and forth under the action of the return spring, so that the connecting rod drives the slide on the cross bar The rod reciprocates, and then the movable plate on the support plate at one end of the sliding rod continuously squeezes and shakes the soil, so that the contact between the soil and the crushing blade on the crushing roller is more frequent, thereby improving the crushing efficiency of the soil, and at the same time, the soil is also It is constantly driven by the movable plate to shake, so that the crushing of the soil will not cause dead ends.

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
