Screening device for soil remediation

Abstract

The invention discloses a screening device for soil remediation. A screening box is included. A feeding groove is arranged in an upper end of the screening box. An upper cover abuts against an inner wall of the feeding groove. A partition plate is fixed to the inner wall of the screening box. A plurality of dividing grooves are arranged in an upper end of the partition plate in a penetrating manner. The inner wall of each dividing groove is rotatably connected with a dividing pipe in a penetrating mode, a plurality of scraping plates are fixed to a circumferential side wall of each dividing pipe, a bearing plate is fixed to an outer wall of the screening box, a power mechanism is arranged at an upper end of the bearing plate, and an air outlet groove is arranged in the side wall of the screening box in the penetrating mode. The device has advantages that a motor drives rotating pipes to rotate so that the rotating pipes drive stirring plates on the rotating pipes to rotate, the stirring plates effectively stir soil at an upper end of the partition plate, the soil is stirred and smashed, and subsequent screening is facilitated; and rotating directions of the two rotating pipes are opposite, then the soil between the two rotating pipes is subjected to a larger shearing force, and a stirring and smashing effect of the soil is enhanced.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a screening device for soil restoration. Background technique [0002] Soil remediation is a technical measure to restore contaminated soil to normal functions; 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 types: physical, chemical and biological. method. [0003] Most of the soil remediation process needs to screen the soil to clean out the sand and debris mixed in the soil, which is convenient for repairing the soil by repairing the liquid, and at the same time avoiding damage to the machine caused by larger particles of sand and gravel. Most of the existing screening methods realize the separation of soil and debris by shaking the screen, but this method can easily lead to blockage of the screen, and frequent cle...
