Description

Technical Field

[0001] The utility model relates to the technical field of thickness detection, in particular to a heavy metal polluted soil screening device. Background Art

[0002] The soil screening device for heavy metal pollution treatment is an indispensable device in the treatment of heavy metal contaminated soil. When treating heavy metal contaminated soil, due to the complexity of the soil, it is often mixed with stones or other debris, so they need to be screened out and treated separately before treatment.

[0003] The existing Chinese utility model patent with reference announcement number CN213854869U discloses a heavy metal contaminated soil screening device, including a box body; a pressurizing mechanism, the pressurizing mechanism includes a hot air blower and a conveying pipe, a hot air blower is fixedly welded to an outer wall of one side of the box body, and a conveying pipe is fixedly installed at the air outlet end of the hot air blower; a feeding pipe, a feeding pipe is rotatably plugged into the bottom of the box body; a filter cartridge, a filter cartridge is fixedly welded to the top of the feeding pipe; a driving mechanism, a driving mechanism is fixedly installed on the surface of the feeding pipe and located outside the box body; a crushing mechanism, the crushing mechanism includes a rotating shaft and a stirring rod, and a rotating shaft is fixedly plugged in the center of the top of the box body. The utility model effectively solves the problem that in the screening process of the existing heavy metal contaminated soil screening device, some soil forms larger soil blocks, which is not conducive to the vibration screening of the soil, and the moist soil is easy to form agglomerates, which block the filter holes and reduce the screening efficiency.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it was found that the screening of heavy metal contaminated soil requires the use of a screening device to screen the debris inside the soil before treatment. When the traditional screening device is screening the soil, the soil is manually poured into the screening device, which causes the upper end of the filter to be blocked when the soil is agglomerated, making it impossible to use it subsequently. When screening the soil, the upper screening structure is easily blocked, resulting in low subsequent screening efficiency, affecting subsequent use. The existence of these problems affects the use of the device. Utility Model Content
